WALLED SHEET-METAL STRUCTURE.

Specification of Letters Patent.

Patented Feb. 13, 1912.

Application filed December 9, 1909. Serial No. 532,204.

To all whom it may concern:

Be it known that I, Pn'rnn M. \Vaon, a citizen of the United States, residing at Miarietta, in the county of \Vashington and State of Ohio, have invented a certain new and useful lm 'irovcment in \l'alled SheetvMetal Structures, of which the: following is a specification.

The object of this invention is to pro-- vide a Walled structure of sheet metal of simple, economical and durable construc' tion the parts of which are adapted to be readily assembled.

v he invention is embodied in the construction herein shown and described the features of novelty the appended claims.

In the accompanying drau'irig-Figure 1 is a section of the line ir n- Fig. 2. Fig. 2 is a section on the line ;r-:r Fig. I, with interior end pieces omitted. Fig. 3 is a section on the line 3 1 Fig. Ft. Fig. l is section on the line 2--2 Fig. t. Fig. 5 is a perspective view of an interlockin; corner member and Fig. 5 is a plan View showing how a straight intermediate interlocking corner member can be added to two corner members. Fig. 6 is a perspective view of a portion of a structure containing the invention SliOiillljI a side about to he added and with portions broken out to show details.

The structure is shown in plain box form of five walls and without a cover or door.

The outer end walls 7 and 7 and the bottom 7 are all formed of a single piece of sheet metal. The vertical margins of the ends 7 and 7* are each bent inward as indicated at 8 and then outward as seen at 9 to form rentrant vertical corners and the horizontal or upper edges of the ends 7 and 7 are each bent mwardly'as seen at 10 then downward as seen at 11 and then inward as seen at 12. The two side margins ofthe bottom 7" are bent upward as seen at 13 and then outward as seen at 14 to form reentrant horizontal corners. Portions of the metal 8 at the top and bottomrorners are cut out as indicated at 8 to permit the insertion of the angular interlocking pieces. The side pieces 15 and 15'- each have their top and bottom or horizontal margins bent inward as indicated at 16 and then toward each other as seen at 17't0 form channels, and their vertical mar ins each bent inward as indicated at 18' and then toward each being pointed out in other as seen at 19. The corners of the side pieces where the inwardly bent margins meet are preferably welded to make a neat linish as seen at 23.

The channels formed by the top and b0ttom marginal portions 16 and 17 receive the plain pieces. The other arms 21 of these interlocking pieces are formed at their ends to engage each other in the channels formed by the marginal portions 10,- 11 and 12. 'lhesc arms 21 are provided for example with recesses 21 and tongues 21" reversely arranged on the two arms 21 so that when hooked into each other and held while lying in the same plane they resist separation when drawn on in that plane in a direction coinciding with the center line of the coin net-ted arms. The two side pieces 15 and 15' of the structure are therefore connected with the member conun'ising the ends and.

hottonn (T. and 7") by properly placing tho plain armsof" the corner interlocking pie es in the channels oi" the side pieces 15 and l5 and then pressing the sides inward toward each other :u'ititthc interlocking arms Ell oi the corner pita-cs are in osition to have their hoolts intei cngag'c. Care should be taken that interlocking arms oi the corner pieces aromatic of such length that they will inter-mon age when the sides are fitted up against their seats on the incur her compri ed of the ends and bottom (7, 7, and i It the corner interlocking pieces are made of metal of ample gage the sides. will he sutticicntly locked in place by simply pressing the interlocking arms into their intended engagement. But to mal =1: sure that they shall remain so locked, and to make a neat finish, and provide also a double Wall at the ends, if desired, it is proposed to employ pieces of sheet metal 22 and 22* cut to proper size and bent outward and upward at its upper edge as shown at 24 and doubled and bent outward at its lower edge as seen at 25 so as to closely fit in the spaces to be occupied and to fit against the inter engaged arms 21 at the top and bottom at each end of the structure to hold said arms engaged with each other. Thus constructed the parts are tightly held together.

The arms 20 or 21 or both can be riveted or spot welded in place, and if this he done the interior end pieces 22 and 22 can be dispensed with.

It will he observed that by this construcarms 20 of the corner interlockingtion the use of rivets or bolts can be avoided at least in the manufacturing of the body and that the structure presents a neat and chaste appearance. The construction is useful in the manufacture of cabinets, chests, boxes, cases and many other forms of walled structure. If the structure be of extraordinary width it may be advanta eons or import ant to interpose an interme iate locking piece 26 between the hook arms 21.

The terms top bottom side and ends are used herein in a special sense because the device conventionally is so shown. In practice for example what is herein termed the bottom might become the back and what is called a side or end might be the bottom.

What I claim is- 1. In a sheet metal structure of thekind described, two parallel walls and :1 connecting wall, said parallel walls provided with bent. over concealing margins, combined with walls joining said parallel walls, and arms connected with said joining walls and extending under the concealing margins of the first named walls, the arms at each side of the structure provided with means for interlocking them at their ends whereby the joining walls are held in position with reference to the first mentioned walls.

2. In a sheet metal structure of the kind described, two parallel walls and a walll permanently connecting them at their cor responding edges, the free margins of said a parallel walls being inwardly bent to form grooves, combined with closing walls to connect the aforesaid parallel walls, said closing walls also provided with inwardly i standing marginal grooves, and angular ieces, each having an arm secured in said ast named marginal grooves and a second arm extending into one of the first men- 5 tioned mar inal grooves, the corresponding i last name arms being interlocked with each other, substantially as described. x

3. In a sheet metal structure of the kind l described two parallel walls and a wall permanently connecting them at corresponding i edges, combined with separate walls to coni grooves of the .marginal groove of one nect the aforesaid parallel walls, said separate walls provided with marginal grooves and angular nieces engaging the marginal said separate walls and having arms interlocked with corresponding arms adjacent the first named parallel Walls.

4. In a sheet metal structure of the kind described two parallel walls and a wall permanently connecting them at correspond ing edges. combined with separate walls to connect the aforesaid parallel walls, said sc 'iarate walls provided With marginal grooves, angular pieces engaging the marginal grooves of the said separate walls and interlocked with each other adjacent the first named parallel walls, and means for holding said angular pieces interlocked with each other.

5. In a sheet metal structure of the kind described, in combination, two parallel walls and a wall permanently connectin them at corresponding edges, separate end walls to connect the aforesaid parallel walls, said end walls having marginal grooves, angular pieces each having an arm engaging one of the said marginal grooves and an arm interlocked with the corresponding arm of an opposite angular piece, and separate inserted walls to hold said angular pieces in' tel-locked.

(1. In a sheet metal structure of the kind described, two parallel walls and a wall permanently connecting them at corrdsponding edges, the end edges of said parallel walls provided with inwardly and outwardly bent flanges forming corners, separate connecting end walls provided with flanges forming marginal grooves, the flanges of the end walls fitting in the at'orcsaid corners, angular pieces each having one arm located in a o1" the end walls and a second arm iincrlochcd with the corresponding arm of an angular piece in the opposite end wall.
