)Patented july 5, E932 UNITED STATES PATENT oFFic BAYARD E. RICHARDSON, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR F THREE-FOURTHS TO JOSEPH R. MCCARGAR, OF GRAND RAPIDS, MICHIGAN DESK CONSTRUCTION Application led December 27, 1926.' Serial No. 157,181.

This invention relates to a desk structure and is particularly concerned with the construction of a desk using sheet metal and wood in combination, and so constructing the desk that the metal parts are lpractically all covered and disguised when the desk is complete with the drawers therein, there appearing only edge portions of the metal used which are capable of being finished to simulate the appearance of wood. If desired, the metal .portions which appear in the front of the desk and also in the back (though this is not of any importance) may be given a distinctive finish which will add to the ap- A further object of the invention is to construct a desk so that its parts may be very quickly and readily assembled, by use of suitable connecting devices such as screws and tie bolts whereby the desk may be iinished as to the parts going to make up the same and these kept in stock from which desks may very quicklyand readily be assembled, after being shipped in knockdown form to a desired designation.

A still further object of the invention is to construct the interior drawer and slide carrying portions wholly of sheet metal making a very strong and durable construction and one which may be. housed within the sides and the rear panels of the desk construction and which is simply and easily assembled therewith.

Many other objects and purposes than those stated will be apparent as an understanding of the invention is had from the following description taken in connection with the accompanying drawings, in which,

Figure l is a front elevation of a desk made in accordance with my invention.

F ig.` 2is a fragmentary enlarged transverse vertical section through the upper portion of the desk, substantially midway between its sides.

Fig. Sis a fragmentary perspective detail of the construction at a front corner of the` metal drawer carrying construction.

Fig. 4 is a similar perspective detail of theA structure at and adjacent a rearv Corner thereof.

Fig. 5 illustrates, in perspective and partly in section, the parts which are used to make up a desk pedestal assembly and the adjacent intermediate drawer carrying unit disposed between the upper ends of the desk pedestals, the parts being shown in disassembled form.

Fig. 6 is an enlarged vertical longitudinal section through the desk at one end thereof Fig. 7 is an enlarged vertical transverse sect1on through one end of the desk.

- Fig. 8 1s an enlarged horizontal sectlonk through the desk at one end thereof, and

Fig. 9 is a fragmentary plan view of the lower metal frame one of which is used with each desk pedestal.

Like reference characters refer to like parts what widened so as to make wider parts 3 (see Fig. 9) making in effect circles, at the centers of which, vertical openings are made.

The sides4 of the desk pedestals are of Woodand at each vertical front and rear edge are curved ,laterally as indicated at 5. These sides may be placed above the frame previously described with their lower portions bearing against the side moldings 2 and with their lower edges resting upon the side iianges l. They areheld in such position by a rectangular frame 6 of wood which is of a size that fits readily into the lower sheet metal frame and lies between the lower edge portions of the pedestal sides as shown in Fig. 6 separating them apart and holding them against the molding anges 2.

Above the frame 6 and resting thereon is the drawer and slide construction which, as' previously stated, is made wholly of sheet metal. This is best shown in Fig. 5 and the details of construction thereof in Figs.`3 and p 4. At the front, spaced a art vertical posts of sheet metal are locate each comprising a web 7, and an outwardly extending flange 8 at the rear ed e of the web and a curved flange 9 at the ont thereof. These posts, which are of substantially channel form, are used at the rear of the drawer carrying frame, being reversed in position so that the flange-8 is in front and the curved flange 9 is tothe rear. Between the posts horizontal bars of sheet metal for-slidably carrying the drawers and the usual slides are disposed each of said bars having vertical upper and lower flanges 10, extending from an intermediate horizontal U-shaped drawer guide 11, the anges 10 and the drawer guides 11 belng made from a single length of sheet metal. At their front ends the flanges 10 are turned outwardly at right angles making ears 12 bearing against the flanges 8 of the front `posts to which they are permanently connected by spot welding. The guides 11 adjacent the front ends are partly cut away, as shown in Fig. 3, so that the bend is removed, whereby gusset plates 13 of fiat metal may be located at one ed e between the upper `lower legs of said U- aped draw guides 11. The sset plates are permanently se- (lrllired in p ace by spot welding to the guides Between the front posts cross bars 14 also formed of 4sheet metal of U-shape are located and spot welded to the front edge portions of the gussets 13. --Within the channel made by anges 8 and 9 of the front-posts an angle bar havlng legs 15 and 16 is located and screw headed bolts 17 pass through the web 7 and the leg`15, the nuts thereof being at the outer vms sides of said leg 15.. It is apparent that by engaging the heads of the bolts 17 with a screw driver this angle bar described ma be drawn tightly s that the leg 15 will ear snuglly against the outer, side ofthe web 7.

T e rear corner posts, insofar as the channel formation including the web 7, flanges 8 and 9, and the angle member having the legs 15 and 16 are concerned is the same as that at the front. The web 7, however, lies against thevertical flanges 10 of the drawer guides and bolts 17a pass through the flanges 10, the web 7 and the leg 15. These bolts 17a are the same as the bolts 17 except that at the rear the bolts 17a do not need to have flat countersunk heads but may be of a round head formation. On the inner side of each of the vwebs 7 of the rear channel posts a second smaller channel of sheet metal is se-` cured b spot welding, it having a web 418, a Afront ange 19 inwardly turned at right angles to the web and a rearwardly turned flange 20 which curves opposite to the curved flange 9 on its adjacent post.

Adjacent the rear ends of and lying between each (pair of spaced apart horizontal drawer gui es is a cross bar of sheet metal 1,sse,174

having substantially like formation, namel a wide vertical flan e 21 and a rearward y extending intermedlate horizontal U-bend 22. The ends ofthe flanges 21 are bent rearwardly at ri ht angles to make ears 23 which are spot wel ed to the anges 10. vThe struclture is further reinforced by gusset plates 24 (see Fig. 4) which are connected to the U-portions 22 and the drawer supporting guides 11, the bends of the U-shaped guides 11 being cut away to receive the gusset plates which are likewise spot welded in place.

This construction of drawer and a' slide support, as a unit, may be placed on the frame 6, the same being let down from above between the opposed edges of the curved portions 5 of the pedestal sides, the edges of said parts 5 passing between flanges 9 and the legs 16. Then by tightening the bolts 17 and 17a said flanges 16 are brou ht tightly against the inner .sides of the eges of said curved portions 5 which bear with their. outer sides snugly against the edges of the curved flanges 9 both at the front and at the rear. Then to finish this part of the assembling a back panel 25 of wood is slid vertically downward in the guides formed between the flanges 19 and 20 of the channels which are located, one at the inner side of each rear post of the sheet metal drawer suppprting frame. As many pairs of drawer guides may be disposed between the upper and lower ends of the vertical corner postI as may be repanel' 25 of the pedestal. Said upper frame of'sheet metal is rectangular in sha with rounded outer corners having para el sides and ends, as indicated at 26, with a central rectangular openingv at which the metal is turned u wardly at right angles, as indicated at 2 this servin to reinforce and strengthen the frame. t the outer edges 'of the frame 26 it Vis formed into a continuous inverted groove 28 from which, at spaced intervals, horizontal ears 29 extend outward. The frame, when placed at the upper end of the pedestal, engages the upper edges of sides 4 with their curved end portions 5 and the upper edge 'of the panel`25 the same extending into the inverted groove 28 as-is evident.

Inorder Ito securely bind all the parts together and at the same time attach support-l ing legs or a base tothe pedestals, long tie rods 30 are used which pass' 'upwardl lquired or desired, this being a matter of delll Esi

ianges of the Vvertical angle clamps and finally through theopenings at the corners of the upper frame 26. The upper ends of the rods are threaded to receive n uts 33 (see. Fig. ti) while the lower ends of thel rodsare provided with heads 32 which are of rounded form and make suitable parts to engage the floor, equivalent in substantially all respects to the well known sheet metal domes now largelyused at the lower ends of the legs of various articles of furniture. Over the upper ends of the legs or feet 3l a cap 31a of sheet metal is placed. rlhe drawers'34 the slide 35 used are of conventional construction.

rihis completes a desk pedestal. In a desk two of the pedestals are used located a distance apart to make what is known as the well of the desk and, usually, between the pedestals, at the upper portion of the well, a center drawer is mounted. The construcwhieli l have devised for mounting the center di wer and separating the desk pedestais is also et sheet metal and is a unit of the desk ronstruction.

The vertical legs of these angle bars are4 spot welded to vertically disposed plates 38 which at the upper and lower edges are turned inwardly to make the. in eifect, corner gussets 39. The upper gussets 39 are attached at their ends to horizontal Z-bars 40, it being understood that said Z-'bars eX- tend between the ends of `said unit. In addition the plate 38 at the front is turned back upon itself in a U-shaped bend making an inner side 4l, which lies against the inner sides of the vertical legs ofthe angle bars 36 and 37 and is permanently secured thereto. Between the ends'of the lower angle bars 37 are sheet metal plates i2 and 43,-the former being at the rear lower side of the drawer and belowv the bottom etat thereof, while the front plate 43 lies over the upper edge portion of the bottom t4 and is curved downwardly around its front edge. An angle bar 45, see Fig. 5, extends around the rear upper edge of the bottom t4 and its endsabut against the vertical plates 38. A wooden back d6 bears against the rear face of the angle bar 45, being held thereagainstby the member 42. See Fig. 2. The upper edge of the back is screwed between the rear Z-bar l0 and an additional horizontal angle plate et? as shown in Fig. 5. The bottom all is permanently secured to the inturned gussets 39 at the lower ends of the plates 38 by screws. rThis unit is disposed between the two desk pedestals near their upper ends and is held by means of securing bolts which pass through suitable openings made in the front and rear plates 38 and through the adjacent inner sides 4 of the desk pedestals. Being open at the front this unit is adapted to slidably receive a drawer, such as indicated at 49 in Fig. 1.

The desk is completed by any conventional top 48 which is laid over the upper frames 26 of the pedestals and bears against the edges of the rim 27, the upper sides of the inverted groove 28 and against the upper flanges of the Z-bars 40. The top is connected by means of screws 50 which pass upwardly through the tongues or ears 29 into said top, while additional screws pass upwardly through suitable openings made in the horizontal upper. flanges of Z-bars 40. The construction of the desk described is one which effectively' combines sheet metal and wood, all of the advantages of strength and durability of metal being obtained and all of the attractiveness and desirable appearance of wood being retained. Furthermore, as is evident from the foregoing description, the various parts of the desk are readily manufactured as separate and complete elements or units and may be kept in stock and quickly and easily assembled into complete desk form. This permits shipment in disassembled form with the consequence of reduced transportation cost, while the assembling when the destination is reachedis accomplished with the use of no other tools than a. screw driver and wrench. The invention is capable of wide variation in detail of construction. Accordingly I do not wish to be limited in any respect to the specific detailed construction described but consider the invention as com prehensive of all forms of structiire coming within the scope of the appended claims detining thc invention.
