Application led August 18, 1923.. Serial No'..8`57,068

My invention relates. to improvements in metal tables in general-,'a' nd has particular reference to'a means of reinforcing a relatively thin metallic face sheet to c same 'from buckling While substantial y elim'- inating the metallic sound.

The principal objects of the invention are v to provide an improved reinforcing .means of the character-described; to provide an 1mm proved deadening means for substantially .eliminating the 'metallic cla'ng which is `ordinaril associated with thin metal sheets;

to provi e an improved construction of the` character described which may be adapted 5 to sheets or surfaces of any area within the desired requirements ;'to provide a reinforcinv and deadening means which, when applied to the sheet will not impair the original level surface thereof but which Will, on the A -1.0 contrary, tend to .eliminate waves or buckles present therein; tojprovide anl improved combined frame work and reinforcing means for a metal face sheet which, when applied to the sheet renders the latter capa leof z being handled as a rigid self-sustaining table member; to provide.` a construction particularly adapted to be made of metallic tubing throughout, thereby securing maximum lightness and also economy of metal; H0 to provide a construction which shall be simple and 'inexpensive in 'design and to manufacture and in general to provide, a neat, rigid, rugged and eiiicient construction of the character referred to.

Referring to thev drawings accompanying this application which show my invention as applied to a table suitable for use as a top for a bedroom dresser or other article of furniture,

Fig. 1 is an under side perspective view o the table. Fig. 2 is a section taken on the line 2-2 of Fig. 1.

Fig. 3 1s a section taken on the line 3--3 Fig. 4 is a section taken on the line 4 4 of Fig. 1, and

Fig. 5 is an enlargement of a portion of Fig. 2.

table is used in its broadest sense as including any sheet or supporting surface with or without legs or other sustaining means of support. eferring to the drawings, 10 represents revent Throughout l the speciiication, the word.v

ythe face sheet which is constructediof vrelatively thin metal, preferably reviouslyflat tened or 4leveled in any suitable device such as what is known in the' trade as a patent .A leveling machine. "Said sheet, as `to its 00 uter margins, is supported upon an underlying rectangular frame constructed throughout of rectangular tubing preferably steel, of comparatively light gauge, so as to provide the maximumv yrigidity with minimum 05 of metal. Said rectangular frame-comprises a pair of side bars 11 and 12 which extend.

.the full length of the face sheet, and a pair of end bars or cross pieces 13 and 14 which are respectively interposed between the adja- `cent ends of the pair of longitudinals 1l and 12. The cross pieces and side pieces 11 and 12 are secured together in any suitable' manner, although in the present'instance I-have shown the corner joints formed by acetylene welding, as indicated at 15 and 16` Said rectangular border frame mayv be made up in advance if desired, and slid into position. under the top orface sheet 10, the side and ,end margins of which ylatter are, S0 flanged over as indicated at 17 and 18 in order to hold said sheet margin and border frame securely together. 'The edge of said flange 18 is permanently secured in position bymeans o-fusible bonds as at 19 of soft or 85 hard solder, but before doing so themarginal deadenin strips are inserted. Said deadening strips 20, both as to those at the margns and the intermediate ones, which will later be described, may be made `of some suitable fibrous porous and more or less ilexible material such as cardboard and are interposed between the under side of the face vdeadening strips 20 and in order still further to secure suchy strips in position against sliding inwardly, I prefer to connect the upper inner edge of the border frame 21 to the adjacent under surface of the face sheet 10 by means of drops or localized applications of solder as indicated at 22. Said bonds 22 not only prevent dis lacement of the deadening strips 20,-butl a so hold downl the mar- 4 ginal portions of the top sheet 10 securely in contact with said deadening stri s 20.

. Hence rattlin or vibration of the si e portionsof the acesheet v1() is prevented and 110 the ordinary case it is found desirable to apply intermediate reinforcing members spaced to suit the requirements ofthe particular top. In this instance I have indicated a series of three similarly constructed and similarly s aced reinforcing or stiiening members. ach of said reinforcing members 23 comprises a length of rectangular light weight tubing preferably running from end to end of the table parallel with the side pieces 1 1 and 12 and underlying they face sheet l() in the same manner as the members of the rectangular border frame.

Each of said members 23 is secured at its ends to the 'cross pieces 13 and v- 14 respectively by any suitable means such as brazing or welding, and, like the members of the rectangular border frame, is suitably spaced below the plane of the sheet in order to permit the insertion of a deadening strip 24 similar in character to the 'deadening strip 20. Said intermediate reinforcing bars 23 also have their edges fusibly united or bonded to the under surface of the sheet 10V by meansof drops or localized applications of soft solder as at 25 and 26, which bonds also serve to hold the deadening strip in position. I prefer to use soft solder for uniting the edges of the face reinforcing members to the under side of the sheet 10 for the reason that when using soft solder, there is less danger of burning the deadening material and, furthermore, which is more important, on account of the much lower temperature, there is no danger of injuring the level surface of the face sheet by overheating.

The described details of construction and operation are merely illustrative of a single application of my invention. the scope of which should be determined by reference to the appended claims, said claims being construed as broadly as possible consistent with the state of the art,

I claim as my invention:

1. In a table, the combination of a metallic face sheet, a reinforcing frame member underlying said sheet, a deadening member interposed between said Sheet and frame member, and means on the under side of said face l' sheet forunltlng ltogether said sheet and frame member beyond the edge of said dead- Leagues ening member to prevent separation of the 'l sheet and frame member, and also to prevent sidewis'e displacement of said` deadening member. l

2. In a table, the'combination of a metallic I face sheet, a substantially rigid reinforcing bar underlying said sheet, a deadening strip of substantially the saine width as that of said reinforcing bar interposed between said sheet and bar, andmeans for uniting togethsaid sheet and bar, and means for unitingl together said sheet and bar beyond the edge of said strip to prevent separation thereof,

and also to prevent sidewise displacement of said deadening strip.

4. In a metallic table, the combination of a thin imperforate metallic face sheet, a hollow metal reinforcing bar underlying said sheet, a stripof deadening material interposed between said4 sheet and bar, and means for'uniting vtogether said sheet and bar comprising fused metal bonds at opposite edges of said bar, said bonds being effective to prevent separation thereof.

5. In a table, the combination of an imperforate metallic face sheet, a hollow' metal reinforcing bar underlying said sheet and having a pair of coplanar spaced edges adjacent said sheet, a strip of deadening ma' terial interposed between said sheet and said bar, and means for uniting together said sheeet and bar to prevent separation thereof and to clamp said deadening strip therebetween comprising spaced localized fused metal bonds connectingy the under side of the sheet to points along an edge of the bar.

6. In a table, the combination of a metal lic face sheet and a metallic frame, said frame comprising peripheral members and a reinforcing bar extending from one of the peripheral members to another, said face sheet being disposed over said frame, and deadening strips interposed between the frame members and the face sheet, said face sheet being held in place over said frame members by means of fusible metal bonds said deadening strips in place.
