CONSTRUCTION UNIT Fi1ed Nov. 9, 1928 /L E 1 I I I I Patented Aug. 23, 1932 UNITED STATES PATENT OFFICE ARTHUR E. JONES, TONAWNDA, NEW YORK, ASSIGNOR TO HENRY WEIS MANU- FACIUBING COMIANY, INC., A CORPORATION OIE INDINA CONSTRUCTION UNIT Application flled November 9, 1928. Serial No. 318,141.

This invention relates to fabricated sheet metal construction units, and aims to provide a partition or panel construction in which the elements thereof may be easily and readily assembled and the resulting units Will be rigid and will have a neat .ppearance.

The nature of the invention may be readily understood by reference to one illustrative construction embodying the invention and shoWn in the accompanying drawing.

In said drawing:

. Fig. 1 is an elevation of a construction unit, a portion of which has been broken away to reveal details on the interior of the unit.

Fig. 2 is a cross section of the unit (on an enlarged scale relative to that of F1g. l) taken on a plane perpendicular to the face of the unit and parallel to one of its edges.

Fig. 3 is a perspective view (also enlarged as compared to the scale of Fig. 1) of a corner of the unit with the edge strip removed.

Fig. 4 is an elevation of a pair of adjoining edge strips, separated slightly so as to show the mitered ends.

Fig. 5 is a development or pattern of the corner of one of the panel sheets as it is out or blanked out and before the metal has been bent into the form shown in Fig. 3.

Fig. 6 is aperspective view of a door made from one of the illustrative units.

The illustrative unit comprises a pair of marginally fianged panels 10 and 11, advantageously made of sheet metal, connected together at their edges by connecting means which provide a r1gid, doublewalled unit. In the present case the marginal flanges 12 of the panels are provided with means in the form of inwardly turned extremities 13 which cooperate with the connecting elements 14 to h old the sheet metal panels in assembled relat1on.

, The connecting element 14 is in this instance in the form of an edge strip whose head 15 lies over the joint between the panels and whose shank 16 extends between the marginal fianges 12 and is provided with means, in the form of books 17 having inclined cam faces 1.8, for engagin g the fiange extremities 13. In the present case the head 15 of the connecting element is arched and made resilient so as to be capable of drawing the hooks 17 tightly against the flange extremities 13, thereby holding the panels together under a resilient tension and removing all looseness and play between the various elements of the unit. T0 secure this result,.the parts must be proportioned so that the arched head is slightly fiatt'ened when applied to set up the necessary tension. In this instance the inclined surfaces 18 on the hooks 17 exert a cam action on the extremities 13 by means of which the panels are drawn tightly together and thus held under the resilient pressure provided by the arched head 15.'

The connecting element may advantageOusly be made of sheet metal folded into the form indicated in Fig. 2. The ends of the connecting element are beveled (in this case at angles of so as to form mitered joints at the corners of the unit.

The flanges on panels 10 and 11 are advantageously made integral therewith by formin g the panels of sheet metal which is blanked out in fiat condition and later bent at the margins to provide the flanges 12 and their e2itremities 13. Fig. 5 shows a development or pattern of a portion of a panel blank showing the outline of the blank at the corner of the panel and (in dot and dash lines) the limes along which the metal is bent to form the marginal fianges 12 and their extremities 13. The cut-away portions at the corner of the blank provide the open spaces 19 at each corner of the unit desirable for the insertion or application of the edge or connecting strip. In assembling a unit, a pair of panels is arranged as indicated in Fig. 3 and marginal strip it is desirable either to cut away or slot' an adjacent edge strip to provide a space for inserting the fourth strip. This is most conedge strip may. be out away orsevered at the point of application of the hinge fittings, therebyagain providing means for inserting the fourth or last ,edge strip. Where the unit is used as a partition member, the side edges of the unit.are usually inserted in recesses in a post or the .like which would serve to conceal a cut-away portion of an edge strip.

Even if all four edges of.the panel were exposed, it would be.possible to cut away a bottom edge strip because that wguld not be visible.- It is apparent from the foregoing that all visible portions of the unit Will present a smooth surface and that the edge strips will abut in.a neatly mitered joint. This joint.is advantageously ,welded, thereby renioving all possibility of such slight relative movement between, the.edge strips as might breakenamel or paint at the mitered corner of the edge strips.

In the present case the unit is advantageously provided with a self-supporting filler in the form of a plurality of thick fiber sheets 22 which are cemented together and cemented on buter faces 23 to the panels, Thus the ,unit is given a solid or substantial quality not possessed by a unit with. a hollow or empty interior. The fiber sheets 23 may advantageouslybe faced corrugated board of commorr construction;

. Obviously the invention is not limited to the details of the illustrative construction since these may be variously 'modified. Moreover, it is not indispensable that all featurcs of the invention be used conjointly since various features may be employed in difierent combinations and sub-combinations.
