PHILIP H. YAWMAN, OF ROCHESTER, 'NEW YORK, ASSIG-NOR TO YA'WMAN & ERBE MANUFACTURING COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

UNIT METAL TRANSFER-CABINET.

Specification of Letters Patent.

Patented Jan. 28, 1919.

To all whom it may concern:

Be it known that I, PHILIP H. YAWMAN,

' a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Unit Metal Transfer-Cabinets, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to metal transfer cabinets, and particularly to the structural improvements therein which cooperate to produce a cabinet which is inexpensive to manufacture, pleasing in appearance,-rigid in structure, and durable in service.

The foregoing advantageous results arise in part from the use of pressed metal style strips which extend vertically along each of the four corners of each cabinet unit and which extend a slight distance below the main frame of the unit thus forming legs for the bottomunit and at the same time formin supporting pillars for each of the units p aced above the bottom unit. These style strips, or columns also serve to aline the unit cabinets one above the other and provide means for locking the cabinets together laterally. 1

Certain of the advantageous'results heretofore mentioned also arise in part from the use of a pressed steel locking-member carried at the rear of each cabinet unit and arranged to engage under a portion of the frame of the nether cabinet unit when the units are stacked one upon another, this arrangement providing a sturdy structure which effectually prevents the tipping of one unit upon another when heavily weighted drawers are pulled out sufiiciently that the weight in the drawer overbalances the weight of the cabinet frame.

A feature of this invention results from securing-the side and top plates of the cabinet unit to the front and rear channeled frames so that the front channel extends below the top plate, thus serving as a stop for the rear end of the drawer to prevent the drawer from being entirely withdrawn inits ordinary use, while the rear channel extends above the top plate thus permitting the drawer to be pushed back flush with the rear end of the cabinet. The extension of the rear channel iron above the top plate also aids in securing a rigid structure and in the interlocking feature between vertically -adj acent cabinets.

Another feature of advantage results from the paneling of the top plate of the cabinet units resulting in a stiffening of the structure and providing narrow friction surfaces for-the top of the back end of the drawer, the utility of this being particularly noticeable when a heavily weighted drawer is withdrawn sufliciently that its center of gravity is brought in front of the rollers upon which'it' rests during movement Another feature of the invention resides in the dustproof finishing panels for closing the ends of sections or groups of cabinets stacked one upon another, and particularly the feature of attaching these panels to the cabinets.

Still another feature of the invention resides in the method and apparatus provided for attaching cabinets laterally so that units may be readily added either to the right or to the left of the section which has been already started; and

Still further features reside in the details of construction, welding and shaping of parts, all of which cooperate in the production of the novel structure hereinafter more fully described.

My invention is illustrated in the accompanying drawings in which like figures designate similar parts throughout the several views, and in which Figure 1 is a perspective of a cabinet unit" with the drawer partially withdrawn.

Fig. 2 is a section taken on the line 2--2 of Fig. 1.

steel plates in a'm'anner to be more fully described hereinafter. The channel steel constituting the rectangle 18 is so formed that the open channel portion thereof extends along the outside of the entire rectangle. The receiver 15 for the drawer 16 is likewise provided with a rearframe member 19 made from channel steel and bent so that the channeled portion forms the outside of the frame. The forward frame 18 is a complete rectangle formed of one strip of channel steel, while the rear frame 19 has three sides formed of similar bent channel steel, two constituting right and left vertical corner support and the third constituting the'top connection between these supports. The lower horizontal limb 26 of this rear frame isformed of pressed steel for a purpose hereinafter described.

-A paneled top plate 20 is electrically welded to the inner side of the top part of the rear frame 19 and is formed and'welded naoaoae inner faces of each are the sheet metal angles .22 which form the lower corners of the of the roller 23, the roller and this boss constituting the sole supports for the drawer as it is reciprocated in the receiver.

The horizontal portions of the right and left angle plates 22 are attached together at the rear by means of the pressed steel locking member 26 which is electrically welded, as shown in Fig. 5, to each of the members 22. The lockin member 26 is formed with a .rear wall 2 slightly greater in height than the depth of the channel member forming the upper horizontal portion of th rear frame." The lower edge, of the wall 27 is bent forward at right angles to the perpendicular and constitutes a short hook 28 which extends under the horizontal portion of the rear channel of the nether unit thus. formin a. lock which effectually prevents the units being separated at the rear until they have been separated at the forward end and until the upper one of the two adjacent units has been moved to the "igear sufliciently that the forward edge of the hook 28 may pass the under edge of the channel 19.

As shown most clearly in Figs. 1 and 6, four style strips or finishing strips 29 are welded to the vertical portions of the front and rear channel frames. These style strips are formed ofpressed steel and have de- -ment' one upon another forming supporting legs for each of the cabinet units stacked one upon another. These style strips also serve to hold the cabinet units in perfect alinement one above another by reason of the manner in which the portion thereof which constitutes the legs of the cabinet units registers with the channeled frame portion of the nether cabinet both at the front and at the rear.

In Fig. 4 the method by which the ends of the channel iron 18, which constitutes the forward frame, are welded between the depending portion of the top plate 20 and the depressed portion of the style strip 29 is clearly illustrated. By the process of electrical spot welding the base of the channel member is welded tothe two adjacent steel members, thus providing a structure almost as rigid as though the forward frame were forengagement with the rollers 23, and also providing a depressed portion 39 for the reception of the. retaining rod for index cards and follower block, in case such are desired. A handle 41 and. a card holder 42 are spot welded to the front plate 34 of the drawer thus securing a strong structure and eliminating the usual unsightly rivets. The upper edges of the front, rear, and side plates of the drawer are folded back upon themselves, as illustratedat 43, 44, and 45,

.thus stiffening and strengthening the upper drawer edges and presenting at the same time a more sightly appearance than could be secured withoutthis expedient.

In Fig. 10 is illustrated the preferred method of horizontal attachment for adjacent cabinet units. In accordance with this method -of attachment a cotter pin 46 is slightly spread and pressed over adjacent walls of registering style strips 29, a sufficient space for these cotter pins being provided immediately back of the front channel frame members and immediately in front of the back channel frame members. This method of horizontal attachment permits a cabinet section to be enlarged either to the right or to the left and has an im ortant advantage in the fact that no specia apparatus is required, the size of cotter pin used being immaterial excepting that pins of sufficient strength to answer the purpose must be selected.

In Fig. 11 a modification of the horizontal attachment is illustrated. In accordance with this modification the upper ends of the right hand style strips are provided with an offset and upwardly, projecting ear 48 which will be engaged by the bottom of the diagonally opposite cabinet unit when the latter is brought .into position. In this manner fou-r cabinet units are united at their common corners. This method of horizontal attachment, however, provides only for increases to the right of a built up section, and while this is usually sufficient it is sometimes found desirable to build to the left in which case the cotter pin method of adjustment is preferable. v

In Fig. 7 is illustrated eight cabinet units stacked in two piles, four high. Althou 'h these cabinets are primarily intended f dr transfer cabinets and as such are usually stogged closets or warehouses, they are height for a section of four vertically stacked cabinet units.

In Fig. 3 is illustrated the method of attaching the dust plate 50 to the upper cabinet un1t, while in Fig. 9 is illustrated the de-- vice for holding the base of the plate 50 in place.

Referring to Fig. 3, the plate 50 is provided with a vertically extending flange 51,

an ear 52 being cut from this flange and bent so as to project over the upper edge of the style strip 29. The base of the member 50 is provided with a flange 53 which extends clear across the plate from side to side, thus stiffening it and also by its projection back of the portion of the style strips 29, which form the le s for the lower cabinet unit, preventing t e plate 50 from springing out at the bottom.

In Fig. 12 I have illustrated a pressed metal buffer 54 which is adapted to fit onto the bottom of the style strip 29 to prevent scratchin the floor and to provide means for readiIy moving a section of cabinets on the floor or carpet. This buffer has side walls 55 and a slightly curved base 56. The walls are very slightly tapered so that they will clamp on to the bottom of the style strip when once firmly pressed'into position.

Although I have described my invention with reference to the details illustrated in the accompanying drawings it is obv1ous dental withdrawal of the drawer from the receiver.
