CABINET-DRAWER.

Specification of Letters Patent.

Patented Apr. '7, 1914.

To all whom it may concern:

Be it known that I, DANIEL E. KURTZ, a citizen of the United States, residing at "Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cabinet-Drawers, of which the following is a specification.

This invention relates to certain novel improvements in cabinet drawers and its object is primarily to provide a drawer which can be readily opened in either direction and which will be adequately supported when in its opened or extended position. It is essential that sliding drawers have some means of support when they are open and this is particularly true in large drawers such as are employed in filing cabinets and other places where considerable weight is carrie by the drawer.

In order that the drawer in my invention, which is adapted to be opened or extended outwardly in either direction beyond the frame of the cabinet, may be suitably and sufficiently rigidly supported when in extended position, I have provided a drawer support slidably mounted in the main frame of the cabinet and upon which the drawer itself is slidably mounted. The support is adapted to be extended longitudinally beond the frame in either direction and it is provided with latches which are adapted to maintain it in extended position when the drawer is open. The drawer itself, however, is provided with releasing devices which are adapted to release the latches upon closure of the drawer to permit the support to be slidden into the frame simultaneously with and by the drawer. During the inward movement of the drawer after the support has been released from its locked position, the drawer is automatically connected to the support, whereby the support is moved inwardly by the drawer. There IS also provided on the frame of the cabinet a device which breaks the connection between the drawer and support upon closure of the drawer, thereby permitting relative move ment of the drawer on the support to permit the drawer to be extended beyond the outer extremity of the support when in extended position.

This invention will be best understood by reference to the following description when taken in connection with the accompanying drawings illustrating a preferred embodiment thereof, while its scope will be more particularly pointed out in the appended clalms.

Referring to the drawings-Figure 1 is an end elevation of a drawer embodying my invention. Fig. 2 is a bottom view of the drawer itself. Fig. 3 is a transverse sectional v1ew of the frame support and drawer taken near one end thereof looking toward the center, Fig. 4 is a section on the line I 1 of Fig. 1. Fig. 5 is a section on the line 5-5 of Fig. 4, showing the drawer and support extended to the left, and, Fig. 6 is a section on the line 6-6 of Fig. 4:, showing the drawer as partially extended tothe right.

My invention is capable of use in any construction where it is desirable to provide a drawer or drawers which will open in both directions, but it is particularly adapted for employment in sectional filing cabinets. Whereas any number of drawers may be embodied in one section, I have shown for the purpose of illustration merely, a single drawer which will be sufiicient for a disclosure of this invention.

On the drawings, 7 designates the top, 8 the sides, and 9 the bottom of a drawer supporting frame. The top and sides of the frame may be open as shown, or closed if desired, or the frame may be extended to accommodate any desired number of drawers similar in construction to the one hereinafter to be described.

The side members 8 of the frame are grooved at 10 near their lower sides to provide guideways or sliding tracks in which is adapted to slide longitudinally a drawer support 11. The drawer support comprises end members, side members, and a pair of longitudinally extending members 12 disposed between the side members, and grooved at their adjacent upper edges 13 to provide a sliding track for a block 14: which is of substantially the same height as the depth of the groove and is screwed to a grooved block 15 which extends beneath the members 12. The block 15 is adapted to slide in the grooves 13 and serves as a stop to limit the outward movement of the drawer support in both directions, by being engaged between the end member of the support and the end ofthe frame, as clearly shown in Fig. 5. It will be evident from the above description that the drawer support is slidable in the'grooves 10 in both directions beyond the end of the frame, and is limited in its sliding movement in both directions by the stop block 15.

A drawer which is designated generally as 16, is slidably mounted upon the drawer support and is adapted to slide longitudinally within the main frame. The bottom 17 of the drawer is elevated as shown in Figs. 3 and 5, and a pair of blocks 18 are secured upon the side pieces of the drawer support to be engaged bythe ends of the drawer project-ing beneath thebottom to limit the outward movementof the drawer on the support, as shown in Fig. -5. The blocks 18 are of the required length to permit the drawer to be openedto its fullest extent in both directions without being entirely withdrawn from the frame.

In order that the drawer support may be maintained in its extended position while the drawer is open to act as a support for the drawer, I have .provided a pair of latches 19 pivotally mounted upon the pins20 between the side pieces and the longitudinal members 12 of the support. These latches are substantially identical in construction and a detailed description of one will suffice for a disclosureof this invention. It will be evident from inspection of Figs. 4, 5 and 6, that the latches are pivoted nearer one end than the other so that the long and heavier end will drop downwardly under the influence of gravity into position to engage with the outer end of the main frame and maintain the drawer support in extend ed position, as shown in Fig. 5, when the support has been drawn out to its limit. It is desirable that the drawer support be maintained in its extended position until, during the closing movement of the drawer, the outer ends of the drawer and of the support are brought into substantial alinement, whereupon during the remainder of the closing movement of the drawer the support should be carried inwardly into closed position with the drawer.

In order to release the latch 19 from looking engagement with the end of the main frame upon inward movement of the drawer to ermit inward movement of the support, I lihve provided upon the bottom of the drawer and near the outer ends thereof, and in alinement with the latches, a pair of blocks 21 having a camface 22 which will engage the shorter end of the latch as the drawer is moved inwardly and elevate the long end above the bottom of the frame into the position shown in Fig. 6. The blocks 21 are also provided with shoulders or abut ments 23 adapted to engage with the outer end of the latch after the latch has been re,- leased. It will be evident from Fig. 6 that engagement of the shoulder 23 with the outer end of the latch will connect the drawer support and drawer together so that and since the support can not be extended beyond the frame as far as the drawer, it is necessary that the connection between the drawer and support be broken to permit the drawer to be extended beyond the support. In order to release the outer end of the latch from engagement with the shoulder 23 on the block 21, there is provided upon the bot-' tom ofthe frame a pair of strips or blocks 24- provided at their inner ends with cam surfaces25. When the drawer and support are brought into substantially closed position, the inner rounded end 26 of the latch will ride up the inclined surface 25 of the block or strip, thereby swinging the latch 19 about its from engagementwith the shoulder 23.?

It will be evident that when the drawer and support are closed the long ends of both of the latches will be supported upon the strips 24: to maintain their outer ends free from the path of the shoulders 23 so that the drawer may be movable longitudinally in either direction upon the support until one of its outer ends engages with the stop blocks 18. Continued outward movement of the drawer in either direction after the end has engaged with the blocks 18, will withdraw the support from the frame until further outward movement of the support, and consequently the drawer, is prevented by the stop block 15. Then the support has been withdrawn to this po'sition, the latch 19 will, engage with the frame to maintain the support in its extended position. Upon closing movement of the drawer, first be released from its locked position relatively to the frame and will then be connected with the drawer to be carried inwardly thereby, as has been previously explained. Suitable handles 26 are preferably provided upon either end of the drawer.

My invention as above described, provides a substantial support for the drawer when opened in either direction, automatically maintaining the support in extended position until the drawer is partially closed, and automatically carrying the support into closed position in the frame upon further closing movement of the drawer. While a preferred embodiment of this invention has been shown and described, it will be evident that various minor mechanical details may be changed without departing from the spirit of the invention the material advantages thereof.
