SHEET-METAL CABINET.

To all whom it may concern:

Be it known that I, FRANK P. VVILLTAMS, a citizen of the United States, residing at Detroit. in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Sheet-Metal labinets, of which the following is a specification.

This invention relates to sheet metal cabinets, and has for its object a sheet metal cabinet that may be constructed almost wholly of folded sheet metal and which may be used for various uses, such as a chiffonier, buffet bureau, or the like. Its advantages will be better appreciated after the detail construction is understood.

The front plate (Z looks into the right angular front lock-seam folds of the side plates in precisely the same manner that the rear plate does. This front plate (Z, however, is provided'with drawer openings 6 which have turned-back strips 7 (Fig. l) which fold over the upwardly-extending reinforcing strips f/ of heavier gauge metal so as to reinforce the front, which would other; wise beweak by reason ofthe large amount of drawer opening therein.

The top of the cabinet is formed by a sheet of metal h which has right-angularly turned-down lock-seam folds i which can be slid from front to rear over the box-like folds turned over from the top of the side plates. The front plate is provided with a 3 is a section on the line 33 of Specification of Letters Patent. Patgntgd J 13 1922 Application filed May 2, 1921, Serial No. 466,004.

forwardly-projecting fold 7c at the top against which engages the turned-down flange Z of the top sheet 72/. The rear plate a has a forwardly-projecting fold perpendicular thereto designated a. This serves as a ledge to support the top sheet 72, at the back, the top sheet being provided with a reversely located lock-seam fold 10 to look over this ledge. The top sheet 7a is prevented from buckling 0r dropping down at the center by the strengthening channels 15 (see Fig. 8). These are simply sheet metal channels with fiat end extensions 16 which at the front engage in between the top sheet and the fold 7a and at the rear engage in between the lock-seam fold 10 and the main body of the top sheet. These reinforcng strips 15 also serve as assistants in guidlng the drawers as they engage the turned over flanges 17 of the drawers (see Fig. 3)

and hence prevent the drawers tipping up and guide the drawers at the top.

The rear plate a extends up above the top of the cabinet body for the purpose of affording a mirror support. It is provided with an opening 0 which has the portions around the opening turned back as at p to make a finished edge for the metal at the opening. The sides of the rearplate a above the body are turned back to form folds (1 (F 2) which receive the edges of the shallow channel sheet 7 to lock the same in place.

This channel sheet 1* has a flange '8 turned into the rear plate at the bottom to support the glass at the bottom. The glass simply slips into this channel sheet between the channel sheet and the rear plate, as is plainly shown in Fig.

The upper drawer support is a four-timesribbed sheet t. the ribs a being formed simply by doubling the metal at the required place. These ribs are arranged in spaced pairs to guide the sheet. metal drawers 1) which will not be described here in detail as they are made the subject of a separate application. This drawer support is provided at the front with a reversed lock-seam fold 20 which can be hooked into the rearwardlyextending flange x at the bottom of the drawer opening. At the rear the drawer support is provided with a downwardlydepending flange y that can be dropped into the fold .2 made in the body of the rear plate and which is turned over parallel with the main plane of the plate and opens upwardly.

This securely locks the drawer support in place without the aid of any separate fastening device.

The lower drawer support comprises simply a plate 1 with turned-down flanges 2 on all four edges that simply drop into turnedup folds 3 of the sides, front and rear plates. At the center the plate is bossed or raised to form the drawer guide 4t. Where this guide joins the remaining part of the sup porting plate a step is formed over whlch the depending flanges 5 of the drawer rest. These two steps act as a guide for the drawer against lateral displacement while the main body of the drawer support acts as a rest for the drawer.

The legs 6 are simply continuations of the side plates but folded double as is shown in Fig. 7 to reinforce them and give them suflicient stability.

From the above description it will be apparent that this cabinet is made solely of sheet metal (outside of the mirror and knobs) and that this sheet metal can all be fashioned on a large production scale by dies and presses. This, therefore, affords an article of furniture that lends itself to production at a very small cost and at the same time, by reason of the way the parts are joined together, it affords a knock-down piece of furniture which, if need be for economy, may be shipped in knock-down condition to its destination. The use of the cabinet is not alone confined to bedroom furniture or to a buffet but manifestly there are a great many other uses, such as kitchen cabinets that could be included within the possibilities of the article.

What I claim is:

1. In a sheet metal cabinet, front and rear plates having turned-over or folded edges, side plates having turned-over edges that are adapted to engage the folds of the front and rear plates to lock the said plates together, some of said plates being provided each with continuations folded longitudinally and medianly into an angular cross section to form supporting legs.

2. In a sheet metal cabinet, the combination. of front and rear plates having turnedback edge portions forming lock-seam folds at the sides, and side plates having perpendicularly-formed folds forming folds adapted to lock into the folds of the front and rear plates to complete the lock seams at the corners, said folds of some of said plates continuing down below the main body of the cabinet with folded continuatious forming legs at the corners of the cabinet.
