REPORTS OF COMPANIES.

A BELATED ATTACHMENT OF FORT WAYNE ELECTRIC FOR $500,000.

ACTION BY THE GENERAL ELECTRIC COMPANY.-MR. R. T. MCDONALD NOT CAUGHT NAPPING.

JUDGE ANDREWS, of the Supreme Court, New York city, has granted an attachment for $500,000 against the Fort Wayne Electric Company of Indiana in favor of the General Electric Company of this city for money lent between May 1, 1892, and May 1, 1894. The attachment was granted on the ground that the company is a foreign corporation.

A deputy sheriff served copies of the attachment on the National Broadway Bank and H. C. Adams, jr. It was reported that the Fort Wayne Electric Company had transferred all its property in this city to the Fort Wayne Electric Corporation.

The immediate cause of the attachment was the appointment in the Indiana courts of a receiver for the Fort Wayne Company on Wednesday of last week. The General Electric Company is a stockholder of the concern attached.

An officer of the Fort Wayne Electric Company said that so far as he could see the attachment would not hold, as it was placed on chattels which were the property of another corporation. The opinion was expressed that the validity of the General Electric claim would depend entirely upon the legality or illegality of the transfer of the electric company's assets to the electric corporation.

Our Chicago correspondent, under date of June 7, sends us the following special despatch received in Chicago that day:

Fort Wayne, Ind.. June 6.-This afternoon R. T. McDonald, general manager and a heavy stockholder of the Fort Wayne Electric company, asked for a receiver for the plant, valued at $500.000. Superior Court Judge Dawson appointed H. J. Miller of Fort Wayne and E. W. Hawthorne of Boston receivers.

Immediately articles of incorporation of the Fort Wayne Electric corporation, with a capital of $1.000,000, were filed. Messrs. McDonald, Lumbard, Gross, Knight and Miller were named as five directors of the new company.

It is a sensational court matter, and it is supposed the General Electric Trust company was to gobble up the Fort Wayne concern with its branches at Chicago and New Orleans and put the plant undeniably in the hands of the Electric Trust. McDonald has made this gigantic deal to save the plant and carry on the business with increased capital if necessary. The deal will create some uneasiness in electric-light circles. The Fort Wayne plant is running a full force of hands as usual.

The subjoined remarkable manifestation of local feeling on the subject, we quote from the Fort Wayne Journal, of June 7, in extenso:

THE TRUST THWARTED.

FORT WAYNE ELECTRIC COMPANY IN COURT.-RECEIVERS APPOINTED AT THE INSTANCE OF MR. R. T. McDONALD.

IT IS TO PREVENT THE GENERAL ELECTRIC COMPANY FROM CLOSING THE LOCAL WORKS.-A GREAT LEGAL BATTLE ON.

The greatest disaster that has threatened Fort Wayne since its inception, one hundred years ago, is averted. A movement was on foot to close the Fort Wayne Electric Works and shut 1,200 men out of employment.

A pay roll of $20.000 a month was to be stopped.

Between us and this calamity stands Mr. Ronald T. McDonald.

Arrayed against him is the powerful General Electric Company and the wealth of Wall Street.

In the face of these stupendous odds-odds that would phase any other man than Mr. McDonald-we predict he will win.

This card, published in The Journal for a week past, will explain Mr. McDonald's attitude.

The electric light interests of the country are controlled mainly by the General Electric Company. and that corporation is owned by eastern capitalists. They have absorbed the Brush, the Edison, the St. Paul, the Thomson-Houston and various smaller electric corporations.

The plan pursued by this gigantic Wall Street combine is to close up the shops of competing companies and concentrate them under the direct control of the General Electric Company on their railroad lines, so as to profit by the shipping business.

Some time ago they practically wiped out the works of the ThomsonHouston Company at Lynn, Mass. and removed them to Schenectady, N. Y. on the line of the New York Central road.

Holding a controlling stock interest in the Fort Wayne Electric Company the scheme of the eastern fellows was to assume control of the local plant at the annual meeting Saturday next, close it up shut the men out and transfer the manufacturing business to Schenectady, N. Y. as they have done with other corporations.

Anticipating this movement, Mr. McDonald applied to the Supreme Court, yesterday, for the appointment of receivers for the Fort Wayne Works.

Mr. Henry J. Miller and Mr. E. J. Hawthorne were selected by the court to take charge of and operate the Fort Wavre plant They qualified and gave bond in the sum of $60,000 for the faithful discharge of their trust with D. N. Foster. George W. Pixlev, R. L. Romy and J. F. William Meyer as sureties.

Simultaneous with the filing of his application for receivers Mr. McDonald organized and incorporated the Fort Wayne Electric Corporation. capital stock $1,500,000 the first holders being R. T. McDonald, Charles C. Miller, S. C. Lumbard Charles S. Knight and M. C. Gross.

The Corporation has contracted with the receivers to continue the business of the Fort Wayne Electric Company and the compact has been sanctioned by the court.

The assets of the Fort Wayne Electric Company are sufficient to pay all of its debts and leave a considerable surplus for distribution to its stockholders, so that no man will lose a dollar.

The capital of the new company is ample for its purposes, and the arrangements they have made are such that no sacrifice in respect to the assets in the hands of the liquidators will be necessary.

Thus, Phoenix-like, rises out of the wreck contemplated by the combine a new company, with a business as broad as the land and branch offices at 44 Broad street, New York; 185 Dearborn street, Chicago; Philadelphia; Pittsburgh: San Francisco; New Orleans; Dallas, Tex.; Syracuse, N. Y.; Portland, Ore. ; Columbus, Ohio; City of Mexico, Mexico; Havana, Cuba, and various smaller points, to compete with the General Electric octopus and defy its power.

Mr. McDonald is doing this for Fort Wayne, for the men who subscribed $25,000 when the integrity of the company was threatened some years ago; he is doing it for the 1,200 employés of the works and their families; he is doing it for his fellow citizens, for his friends and his home, at a time when he could dispose of h's interests at his own price and continue with the General Electric Company at his own salary, with headquarters in New York.

A great legal battle is on and in the struggle for the life of the Fort Wayne Company, Mr. McDonald can rest assured of the sympathy, support and good will of the citizens of Fort Wayne, who are sure to appreciate his loyalty to the metropolis of northern Indiana.

The latest developments are given in the following dispatch, of Sunday last:

FORT WAYNE, Ind., June 10.-Judge Dawson of the Superior Court, on petition of receivers of the Fort Wayne Electric Company, yesterday issued a temporary injunction and restraining order to prevent the stockholders of the company from holding an annual election yesterday, and also to enjoin them from attaching property in other States which now legally belongs to the receivers. This is to hold off the half million attachment in New York.

NEW HEADQUARTERS OF THE CENTRAL ELECTRIC COMPANY, CHICAGO.

WHEN a little over seven years ago a new firm engaged in the electrical supply business in Chicago, with rather modest quarters at 38 La Salle street, a good many wiseacres dubiously shook their

NEW HEADQUARTERS OF THE CENTRAL ELECTRIC COMPANY, CHICAGO.

heads, wondered where the new comers would get their business and predicted that the concern would not last long. In spite of these predictions, however, the business of the new firm grew and prospered so that but a year had passed when larger premises had to be secured, the company moving a few doors south to No. 42, where, with a three-story and basement building, they were better able to meet the demands of their constantly growing trade. Less than two years sufficed to demonstrate that still more room and better facilities were needed, and on Jan. 1, 1890, the Central Electric Co., by this time recognized and acknowledged as one of the leading supply houses of the West, took possession of the building at Nos. 116 and 118 Franklin street, where for over four years the well-known "Okonite" sign was a familiar feature to the electrical people of Chicago and other cities. That in spite of the universal business depression of last year the Central Electric Company should once more find it necessary to seek larger quarters and better facilities for handling goods, speaks volumes for the business sagacity, enterprise and management of the two gen

tlemen at the head of this popular concern. Mr. Geo. A. McKinlock, the president, has been connected with the company since its inception and is so well known to the entire electrical frater

ally for this company. The company has its own factory (at Columbus, Ind.) for making white oak cross arms, pins and brackets. It is also agent for the Washington Carbon Company, and of course handles a most complete line of electrical and kindred supplies from a push button to a submarine cable.

A complete description and illustration of their new quarters is entirely beyond the scope of a newspaper article, and we therefore confine ourselves to a brief mention of the principal features. In a former issue of THE ELECTRICAL ENGINEER, we mentioned their new location at 173-175 Adams St. Our illustration gives an excellent view of the exterior of the main store. This is the large and commodious building formerly occupied by the General Electric Company. It fronts 50 ft. on Adams St. and runs back to the alley, a distance of 175 feet. The large and commodious salesroom is on the ground floor, our illustration giving a view of the retail department on one side and the conveniently arranged general and private offices on the other. The basement and second floors contain the stock in bulk, a complete list of which fills a quite formidable volume, which might be more aptly termed a cyclopædia than a catalogue. In the rear of the main floor the shipping and receiving rooms are located, both opening on the alley north of Adams street and connected with the upper and lower floors by large elevators. Throughout the entire establishment everything is arranged and classified in a systematic manner, and all needed facilities are provided for the quick handling and shipping of orders. As may be imagined, the several departments are in charge of able and efficient lieutenants, among whom may be mentioned Mr. Chas. G. Burton, in charge of con

nity that a repetition of his personal history seems superfluous. In his endeavors to make the Central Electric Company the leading electrical supply house of the country he has been ably seconded by Mr. Chas. E. Brown, who, beginning as salesman six years ago, has by energy, perseverance and unqualified business ability become the secretary of the company.

One of the most potent factors in the steady growth of the company's business is the fact that besides carrying at all times a complete line of first-class staple goods, they have always handled only standard specialties of the highest grade, nothing of doubtful merit being ever allowed a place in their stores. The Company since their start, have been the Western Agent for the Okonite products, and so well has that part of their business been handled that to-day the word Okonite has almost become a synonym for high quality where insulated wires or cables are concerned. The company is also general western agent for the Interior Conduit &

duits and electric lighting, W. R. Pinckard, house goods, and Geo. W. Vernor, cashier. As our readers no doubt know, the company have branch houses at St. Louis and Kansas City, Mo.

CANADIAN NOTES.

THE ALLGEMEINE ELEKTRICITAETS-GESELLSCHAFT, of Berlin, Germany, has appointed the firm of Munderloh & Co., of Montreal, sole agents for its manufactures in Canada. This German company enjoys a universal reputation for the excellence of design and construction of its electrical apparatus and machinery, of which it is one of the largest manufacturers in the world. All kinds of electrical machinery and supplies are made by the company, including dynamos, motors, complete electric railway equipments, insulated wires, arc lamps and the A. E. G. incandescent lamps. Over 10,000 of these high grade incandescent lamps are turned out daily, and even this large output is to be doubled to meet the demand. The company also make a specialty of alternate current machinery for long distance power transmisson, in which branch it was a pioneer, having undertaken and carried out in connection with the Oerlikon Works, the transmission from

Insulation Company's goods, including the well-known Lundell motors and dynamos. It also makes a specialty of the celebrated Helios arc lamps for direct and alternating currents and the new Pharos incandescent lamp, the latter being manufactured especi

first demonstrated practically the possibilities of electricity in this direction. Messrs. Munderloh & Co., though new to the electrical trade, have been long established and are favorably known to the commercial world. They have secured the services of Mr. John A. Burns, as manager of the electrical and mechanical de partment of their business.

THE GEARY & MOSSOP DOOR SPRING.

THE door spring shown in the accompanying illustration is one of the latest products of Messrs. Geary & Mossop, of Chester, Pa., of which Mr. Craig R. Arnold is the selling agent. This spring is constructed on new principles, avoiding the use of such metals as will rust and corrode, affecting the efficiency of the device. The principal deviation is the use of a long phosphor bronze spring, one end of which is fastened in the brass head plate which secures it to the door; the other end of the spring has a small brass washer fastened to it, and located between these ends is a German silver contact strip which is bent in the form of a loop, thus giving great flexibility to the contacts. The binding screws have conical heads and the German silver tongue makes or breaks the circuit as desired between these screws. The wires are fastened under the heads of the latter.

The Geary & Mossop Door Spring.

Should these heads become worn in time by use they are readily changed to a new position, presenting a fresh surface for contact. The use of the phosphor bronze spring in this shape, secures noticeable advantages. Instead of the pin being rigid, it is very flexible and the German silver tongue is readily changed from one turn to another, which tightens or loosens the contacts as desired. Another advantage that will be appreciated by artisans is the fact that a single bit bored into the frame will admit all of the apparatus, no chisels or other tools being required. The hole which admits the insulating head leaves ample room for the wires to be connected.

HILLHOUSE PRIMARY BATTERY FAN MOTOR.

A CORRECTION.

Through some regrettable inadvertence, not clearly traceable, the notice of the Hillhouse Fan Motor printed in THE ELECTRICAL ENGINEER of June 6, contained an illustration of the Lundell Fan

MOORE ELECTRICAL ADVERTISING SYSTEM.

A striking amplification of the electrical display system of D. McFarlan Moore which we described on May 10, 1893, is that embodied in the show wagon of the manufacturers of "Soapine." Miniature incandescent lamps are arranged at about 2 inch centres over the entire surface to be used as a sign and placed in the centre of the truck.

The curtains surrounding the driver's seat also enclose the batteries. a small operating board, which consists of as many circuit closers, arranged in push-button form, as there are lamps, and the operator.

The operation of the device consists in utilizing only such lamps, by means of the push-buttons, as are required to produce a specific effect, all of the other lamps remaining dark. When it is desired to change the design the lever on the operating board is thrown, which returns all of the push-buttons to their normal positions and all of the lamps are out, but ready to be lighted again so as to produce any design desired.

It is evident that the driving of a vehicle of this nature through the principal thoroughfares at night with its brilliant and constantly changing illumination and advertisements, will attract marked attention.

THE INGERSOLL "PEERLESS" TELEPHONE

OUTFIT.

A very neat little telephone outfit for private lines is being introduced by Messrs. Robert H. Ingersoll & Brother, of 65 Cortlandt street, New York. It consists of two receivers, which serve also as transmitters, two call bells, two cells of dry battery, 50 feet of annunciator wire, 150 feet of galvanized iron line wire and six insulators.

One of the station sets is shown in the accompanying illustra

tion. The call bell is of a special type and made solely for this outfit. That ordinarily furnished with this outfit is constructed to ring for a distance of one mile and under, but bells of greater capability are furnished with outfits for long distances. The bell is mounted on a polished hardwood backboard, and the whole is handsomely finished. Though the outfit is very cheap, it is also neat and attractive in appearance. From the board the re

The error was entirely the fault of THE ELECTRICAL ENGINEER and was in nowise due to the Armature Bell Co., makers of the Hillhouse Fan Motor. This correction is especially called for in view of the remarkable claim that the Hillhouse 8" Fan Motor runs at a high rate of speed by the application of less than one watt.

SALE OF THE SHAVER TELEPHONE PATENTS. Notice is given that the Receiver of the Shaver Corporation, will sell at public auction, at No. 7 Broadway, on the 19th of June, at 2 P. M., all the patents, patent rights, and other property of the Shaver Corporation, including all the right, title and interest of said corporation in territorial leases and other contracts, as well as its entire stock of telephonic and other equipment.

ceiver and transmitter is suspended by telephone cord and at the back of the board, concealed from view, are the switches and connections, which are automatically operated by two push buttons at the side, one to ring up and the other to connect the telephone with the line wire and battery. The batteries are made especially for the "Peerless" outfit with a view to long life and strength.

The makers guarantee the outfit to work perfectly over 1,500 feet of No. 18 copper, or No. 10 iron, wire. By adding an extra battery to each end they extend this guarantee to 1⁄2 mile, and with another battery added to each end, to one mile. The set is simple, well adapted to short lines, and should find a ready sale. ¡¡

ALBERT LEA, MINN., has started a Strowger telephone, exchange, with an initial list of 50 subscribers. The plant is due to the energy of Mr. Frank B. Forbes, lately the treasurer of Freeborn county.
