trailing over the floor as is necessary when the connection is made to one of the lamp sockets over the bench.

Turn Tables, Lifting and Moving Appliances.-In many repair shops where the floor area is limited or where the floor space is broken up by a number of posts it is often difficult to move cars about even under their own power and it takes considerable manoeuvering to head the car around in the other direction. The ideal solution of this problem is the turntable in its various forms. The simplest and cheapest is in the form of a small wheel truck as shown at Fig. 13, having the wheels mounted on a swivel carriage so they

can run in any direction. To use this useful accessory the first step is to jack up the car as shown at A, and then run the truck under the wheels letting the wheels down when the truck is in place. The car may be run onto the trucks under its own power at one end while it is necessary to raise the other two wheels in order to use the small truck. When four of these are used, one under each wheel, it will be possible to swing the heaviest car around without much exertion.

An objection offered to the large turntable is that a pit is necessary in order to have these flush with the floor level, and most of the structures offered are costly. A very simple arrangement that will work very well without requiring alterations to the floor is

shown at Fig. 14. This rests directly on the floor and consists of a circular iron track having a number of ribs or spokes radiating to a central hub which serves as a pivotal point for the load carrying carriage. The carriage is made up of two channel iron beams fastened together by a spacer casting, having at its center a suitable. bearing to engage the pivot pin. This serves merely to locate the load carriage and is not called upon to support any of the weight, which is carried by a series of wheels resting on the track and Securely attached to the side flanges of the channel section beams. As the height of the beams from the floor is but two inches, it is

ssible to use a pair of wedge shape planks as an approach to the turntable. The side of the channel irons also serves a useful purpose sides offering a means of securing the supporting wheels and spacer frame, inasmuch as they offer a guide so the wheels of the rar cannot run out of their correct path. These turntables may be ecured in sizes, capable of handling any weight of car and will De found an effective substitute for the more expensive built-in turntable.

Two forms of built-in turntable are shown at Fig. 15. It will e observed that with these it is necessary to make a pit in which a portion of the mechanism is concealed. The form shown at A is uilt up of angle irons and steel plates and the load is carried at

the centre by a pivot or step journal mounted on a substantial concrete base and at the outer periphery by a series of rollers carried in supporting castings securely anchored to the concrete foundation. The form shown at B, carries the weight on a large ball bearing and has an added feature of having a catch basin for water and other drippings from the car at its centre, so this material will be conducted to a drain instead of filling the pit as is the result when no precautions are taken for drawing the liquid off. The design shown in section at C, is a modification of the type illustrated at B.

One of the most useful of the accessories comprising the assembling floor equipment is the load-raising and supporting jack, various forms of which are shown at Fig. 16. The type at A, is a ratchet form having a single trip lever which can be set so that the same movement of the actuating bar will either raise or lower the lifting ram as desired. The jack at B, is similar to that at A, except that the lifting ram is provided with a double head, making it possible to use the jack on those low axles where it is difficult to get the jack directly under the member to be raised. The jack at C, is a double geared arrangement in which the nut serving to raise the lifting screw is turned by bevel gears worked by the customary lever. The tire saving jack which is shown at D, is used for keeping the wheels of cars that are to be stored for some time off the door and thus relieve the tires of the car weight. These jacks have the advantage of being very quickly handled and are used one under Fach hub cap of the car to be raised. The lifting ram may be adjusted to suit different wheel heights by means of a series of ratchet teeth which enable the lifting link to secure either a long or a short hold on the ram member. In addition to the types of jacks shown, a number of other forms have been marketed which do not give the quick lifting necessary for use in making repairs, but which ire much stronger and better adapted for weight carrying purposes Then the car is to be supported for any length of time. The form hown at E, is composed of three substantial wooden legs, forming - tripod and jointed together at their apex by angle pieces of steel. The lifting ram or screw may be raised or lowered by imparting moion to the nut resting on top of the wooden tripod. The form at F,
