UNITED STATES PATENT OFF-ICE PETER M. WEGE, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO METAL OFFICE FURNI- TURE COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION OF MICHIGAN METAL-TABLE CON STBUCTION Application filed December '27, 1920. Serial No. 157,075.

This invention relates to a table made of sheet metal and equipped with a linoleum upper surface or top. It is an object and purpose of the present invention to construct a table which is made wholly of sheet metal,

except for the linoleum upper wearing surface, and in which the linoleum is attached to a sheet metal support by means of sheet metal border bands serving to retain it in place. A further object and purpose of the invention and one which is of primary significance is to construct the table of parts which may be very quickly and easily assembled or disassembled, this making it possible to ship the construction in its knock-down form wherein it occupies relatively little space, and which may be assembled when its destination is reached in a very simple manner, the only tools required being a screw driver, and there being no particular skill required of the one making the assembly. Many other objects and purposes than those stated will be apparent as understanding of the invention is had from-the following description taken in connection with the accompanying drawings,

in which, a

looking-in a forward dir'je'c- In the construction of the table a rectangu lar supportingframe over which the top is placed, is provided, including a rear side member and end members which are of the same formation, each being made from a single plate of sheet metal, formed with a vertical lip l at its upper edge which is then bent inwardly for a short distance to make a horizontal ledge 2, thence again extended downwardly, as indicated at 3, in a plane parallel with the lip 1. F romthe lower edge of the section 3 a flange 4 is turned horizontally. If the table is not to have drawers the front side of the frame will be a duplicateofthe rear side. It is many times desirable however, to construct the table so that drawers may be mounted under the top and drawn outwardly at the front side. 'In such case, instead of using a front side similar to the rear side including the sections 1, 2, 3 and 4, as described, a front is provided including a. lower channel having a vertical web 6 and upper and lower flanges 7 which lie horizontally and extend rearwardly, the flange 8 being considerably wider than the flange 7 and lying in the samehorizontal plane with the flanges 4 of the rear side and end members, previously described. Above the channel an angle is located having a vertical leg 9 in the same plane with the vertical web 6 of the channel and a'horizontal' leg 10 turned rearwardly from the lower edge of the leg 9. At the ends of the angle and channel, spacing members of sheet metal are provided in the form of short angles having two' legs 11 and 12 atright angles to each ather, fromone of which theleg 11 as shownv finthe"drawing," horizontal ends 13 are bent. '{The upper end '13 lies underneath the leg 10 :whilefthe lower end- 13 lies above the upper flange/Z. Aperlnanent structure isv made by spot-welding or otherwise suitably securing egendsl3xto said le and flange. These sides and ends of the. table frame are connected .at their. :cjorner s by metal brackets, each com- ;.,prising" twofar'ms [5- located at a; right angle to E-eachotherm; The arms lie ;.-against 1 the inner fi'eidesjIof-the lips li'andover' the ledges 2 and j against the' vertical-leg 90f the upper angle r at the front of the table frame, as best shown in Fig. 1. A. permanent connection is made 1 in any suitable manner preferably by spot welding. In addition when the table is assembled the corners are strengthened and reinforced by gusset plates 14 which are disposed to lie over the horizontal flanges 4 and 8 and are permanently secured in place when the legs of the table, as will appear later, are connected in place.

It is evident that drawers may be slidably placed in this frame entering between the orizontal leg 10 and the upper horizontal flange 7 of the two members at the front of the table frame. used but in practice the space in the length of the frame is divided into any desired number of compartments by means of vertical partitions 16 (see Fig. 3). Apartition 16 at its upper edge is welded to the vertical leg 17 of a horizontal angle member which is completed by an upper horizontal leg 18 and ends 19 bent from oneof the legs so as to lie against the inner side of the leg 9, previously described, and also at its rear and against the inner side of the lip 1 of the rear side of the frame. The manner of attaching this horizontal angle member will be later described. At its lower d e the partition 16 is bent at' right angles, as in icated at 16, to rest upon the flange 8 and at either side two angles are permanently attached, having upper horizontal legs 20 and 2O while the vertical legs 21 and 21 lie against'the partition 16 and are permanently secured thereto by spot welding. Near the ends of the table horizontal channels 22 secured to the plates 14, are disposed and on the up r flanges thereof and on the flanges 20 an 20 drawers may be slidably mounted. The legs are formed of sheet metal preferabl in one piece, bent into rectangular form and having four sides 23, 24, 25 and 26. Two of the sides, 25 and 26 as shown, extend above the adjacent sides 23 and 24 of the leg as indicated at 27 and 28. Angle connections, each comprising a vertical leg 29 and a horizontal leg 30, are disposed, one at the upper edge of each of the sides 23 and 24. The vertical legs 29 are permanently attached to their respective sides 23 and 24 and the horizontal legs extend laterally beyond said sides 23 and 24.

When the table legs are attached to the frame the legs 30 of the angle connections come underneath the flanges 4-and 8, previously described, and suitable connecting bolts 31 are used the same passing through the legs 30, said the sset plates 14, this being fully shown lgs. 3, 4, 5 and 6. In addition the extensions 27 and 28 to the sides 25 and 26 of the table supporting legs, at their upper ends come inside of the arms -5 of the corner connecting brackets of the table frame. Screws 32 are usedwhich pass through said extensions 27 and 28 and through openings in the arms of said brackets. In the same way One long drawer could be flanges 4 and 8 and through screws 33 pass through the ends 19 provided on the horizontal angle bar having legs 17 and 18 through the part 9 andthe lip l on the rear side of the table frame.

The screws 32 and 33 thread through suitable openings made in the webs of horizontal channels which lie at each side and end of the table frame near the upper edges thereof, as shown in Figs. 3, 4 and 5. These channels include a vertical web 34 and upper and lower outwardly extending spaced apart flanges 35 and 36. Said channels extend entirely around the frame of the table and are connected at the time said legs are bolted and otherwise attached in place by means of the bolts 31 and screws 32 and 33.

Over the frame thus connected together and supported by vertical legs at each corner, the top is placed. In practice the channels having the webs 34 and flanges 35 and 36 are laid in the sides and ends of the top structure before application is made to the frame of the table so t at the attachment of the channels at the same time secures the top in lace.

The top structure includes a at upper plate 37 of sheet metal which at its side and end edges is turned back on itself making the bend indicated at 38. After being turned inward a short distance a reverse bend or U- shaped loop, indicated at 39, is made in an outward direction and the metal is then extended downwardly making a vertical sect-ion 40, terminating in an inturned flan e 41. The distance between the flange 41 and th e under side of the second bend or loop 39 is suflicient that the flanges 35 and 36 of the side and end channels previously described may pass free- 1y therein yet make a fairly snug fit. The loop at 39 which is of U-shape receives a horizontal section 42 of a metal border strip which is completed by an upwardly and inwardly inclined inte ral section 43, making securing flanges whic bear a ainst the edges of a sheet of linoleum 44 p aced upon the metal plate 37. This particudar structure of to for a desk or table is not new in this application, being fully shown, described and claimed in my prior'application, Serial Number 121,769, filed Jul 12, 1926.

The construction escribed is very practical and is easily formed and assembled so far as the parts need assembly at a factory, by means of suitable tools and dies. The ship ment of the table ma be made in knock-down form with the table supporting legs, the gusset plates 14 and the top structure detached. When the destination is reached and assembly is to be made it is necessary merely to fit the parts together and use the securing bolts 31 and screws 32 and 33, it being evident that the assembly of the table is with it turned upside down on a floor so that the bolts and screws may be readily put in place and tightened' The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure comin within their scope.
