In the previous chapter we considered in detail the machine tool equipment necessary in the various departments of the machine shop, and the location of the machines in each group or department, all arranged for convenient supervision and for the ready handling of the stock and the finished parts.
In that article the machines in which the work was to be done were considered. In this article it is proposed to consider the tools for use in these machines, including a department for making them and proper arrangements for their care, such as providing a place for their safe keeping and regular issue to the shop. It is also proposed to consider, in connection with the storeroom for tools, the arrangement of the storerooms for the smaller kinds of rough stock, and such purchased parts as are received complete from outside dealers or manufacturers. This plan leads us into the office portion of the building, and consequently a brief explanation of this part of the establishment does not seem out of place, inasmuch as it is, in a purely manufacturing plant, so intimately connected with all the machine shop operations, rather than partaking of the commercial side of the marketing of the product.
The large engraving cut, Fig. 81, accompanying this chapter, is a plan of the front portion of the machine shop building, showing the relative location of the offices, tool-making department, storerooms, etc., and the essential parts of their internal arrangements.

The main entrance to the office part of the buildings is through wide double doors from a large porch and opening into a public space in the portion devoted to office arrangements. The divisions of this portion of the building are clearly shown in the drawings. Upon the outer side are located the superintendent's public and private offices, between which is the stairway leading to the drawing room above, and the necessary toilet conveniences. The public space is separated from the large central space of the general office by a railing, doors opening from both these into the superintendent's public office.
The bookkeepers’ desks are so arranged that a cashier's window opens into the public space. The timekeeper's desk is surrounded by wire netting, secluding his work from the general work of the office. A door leads into the gateway space, across the large platform scales and into the tool room portion of the building opposite. At one side of this door and as far away from the general work as may be is the telephone booth. A wide hall leads from the central space to the machine shop proper, and divides the private office from the purchased parts storeroom. This latter is so placed because the purchase, receipt, and issue of such stock is more intimately connected with the office work than that of the rooms in the opposite side of the building.
The tool-making department is purposely placed away from the general machine shop, as a too intimate connection with it does not seem desirable in practice, while it should be convenient to the drawing room and the pattern shop, which may be reached by the stairs next to the rough stock room, as shown. It occupies the entire front of this square, front structure and is provided with a variety of machines rendered necessary for the making of modern tools and fixtures for properly machining small or medium sized parts. The character of each of these machines is indicated on the drawing. It is also provided with the grinding machines for grinding such tools as lathe tools, planer tools, twist drills, etc.
It will be noticed that in providing the machine tools for making jigs and fixtures particular attention is paid to grinding facilities, since these are in many cases the best adapted to such accurate work, both as to producing good work and to doing it economically. Large pieces of heavy fixtures may, of course, have to be planed in the planing department, but these cases will seldom occur. The tempering of tools will best be done in the forge shop, the tools being sent there in quantities when possible, rather than to attempt such work in the tool-making room with hand forges.
A foreman's office is provided so that he may have a proper place for keeping the records of the work of the department as well as a private room for convenience in making such sketches, plain drawings, or details as he may find necessary in carrying out the plans for tool making (these are not always
worked out in sufficient detail by the drawing room force), or such as he may wish to devise himself for special work and develop as the necessities for them
To avoid confusion in the tool-making department, a tool storeroom is provided, where the usual supply of lathe and planer tools, twist drills, taps, reamers, arbors, etc., is kept and issued to the tool-distributing points such as the general room near the engine room and the foremen's offices. In this room are also kept, when they are not in use, the jigs and fixtures necessary for machining small parts, as they can be better cared for here than in the machine shop. The entrance to this room for the workmen is so arranged that he enters a space in front of a counter and has no access to the main space of the room. This will prevent confusion and enable the tool keeper to do his work quickly and properly.
To save unnecessary distance in reaching all tools and fixtures the alcoves of shelves are so placed that the alleys all terminate near the issuing counter. At the right is a convenient bench arranged with arbor racks as shown in Fig. 82. These racks will accommodate arbors from 4 to 7 feet in length. The same form of racks
may be arranged for any length too long for conveniently placing on the shelves. Beneath this bench are strong
be placed heavy jigs and fixtures.
Fig. 83 shows cases of inclined shelves arranged with strips for holding such tools as drills, reamers, short arbors, and similar tools, and at the far
Fig. 82. -- Bench, with Rack for Long Arbors,
Boring Bars, etc. end another form of arbor rack. This may, if preferred, be arranged similar to the arbor rack shown in Fig. 82. The series of inclined shelves is continued as high as is within convenient reach, and above this point horizontal shelves are provided which will be found convenient for holding jigs, fixtures, and similar articles that are seldom used, and not too heavy to be stored at that height. At the base of these cases a series of large drawers is located. They will be found very useful in storing small tools not needed on the shelves, and a variety of such
articles as are best kept in such a receptacle until wanted for adding to the regular issuing assortment on the inclined shelves.
In Fig. 84 is shown a form of case of inclined shelves for longer tools than can be accommodated in the cases shown in Fig. 83. Otherwise the arrangement is the same. The ends of these cases may be conveniently used for the posting of blueprint lists of regular or standard sizes of tools in stock, from which it will be easy to ascertain if a certain tool wanted is kept on the shelves. They may be used as tool check boards, being convenient to the desk and counter.

Fig. 85 shows a file case in which a regular system of arrangement of the files of different lengths, cuts, and shapes are provided for, so as to make the memorizing of their location easy and convenient. It will be noticed that the smaller files, as the 3-inch, 4-inch and 5-inch files, have each one shelf provided for them, while all of the larger sizes have two shelves to each length, as more different shapes and cuts of these are required. Also, that the coarsest cut is placed at the left and the triangular, square, and round shapes follow them toward the right, and that the files of each length are arranged in the same regular order. This arrangement will save much time in issuing files, as well as in distributing stock when it is received. The labels showing the shape, cut, and length are placed on the edge of the horizontal dividing shelves, the shape being shown as in the drawing. At the base, and below convenient
