Fig. ,7 is a' longitudinal vertical section through oneofthe arms. 1 i I Y Referring to, the accompanying drawings, wherein similar reference characters des ig-, nate similar parts throughout, the improved chair comprises a seat frame made up ofsides 10 and ll, a front side 12, and a back side 13. These sides may be formed of any material and .are preferably formedof wood. The ends of the sides are disposed in spaced rela tion to each other, thus forming recesses'la, 15, 16 and 17 at the corners of the seat frame. Diagonal connecting members 18 connect the sides across the corners and these are prefer? ably provided with mortises 19 extending into tenons 20 which are arranged perpen dicular to the lengths of' their respective sides. The connecting members 18' thus having a mortise and tenon joint with the sides, firmly lock the sides ofthe seat frame against separation. These may be assisted by driving suitable'fastening elements 21, such as nails, through them into the sides as shown. ,Any suitable springs or seat may be mounted in the se'atframe and covered by any suitable upholstery. 1 o v I A'back leg structure is provided comprising a pair of back legs 22 and23. These are connected across the topbya cross member 24 which may have applied thereto suitable forming pieces 25 which will shape the top of the backleg structure to give it a pleasing and attractive appearance. A cross. member 26 connectsthe back legs 22 and 23 at about the level of the arms and a suitable back, which may be upholstered, may be mounted between the back legs and between the cross members 24 and 26. A third cross bar 27 connects the back legs 22 and 23 at a lower point and this cross bar is adapted to have the back side 13 of the seat frame positioned thereon. On the forward sides of the legs 22 and 23 there are secured upwardly directed wedges 28 and 29 formed of metal and having their sides bent upwardly, Complementarysockets, which are somewhat channel shaped in cross section, are secured to the rearends of sides and 11. These sockets are indicated at 30 and 31 respectively. r

In assembling the seat frame with the back leg structure, the seat frame is so positioned that the back legs 22 and 23 fit within the recesses and 16. The sockets and 31'are positioned above their respective wedges 28 and 29 and the seat frame is then lowered, causing the wedges to enter the socketsand the back 13 of the seat frame to rest on the cross bar 27. Screws or other fastening elements 32 may be driven upwardly through the cross bar 27 into the back 13 of the seat frame, thus firmly fastening the back of the seat frame to the back leg structure. 3

A pair of forward orfront legs is provided, these legs being indicated at 33 and 34. They may have any desired configuration to produce a pleasing and ornamental appearance but are shown as having squared portions 35 which will fit snugly in the recesses 17 and 14 respectively at the forward end of the seat frame. Screws 36 are driven diagonally into the squared portions 35 of the front legs. These screws on assembling the front legs with the seat frame are adapted to be extended through apertures 37 in the for ward connecting members 18. Wing nuts 38 may be then applied tightening the forward legs in the forward recesses 17 and 14.

The upper ends ofthe forward legs are slotted as indicated at 39 and are provided with' small wedges 40 which originally are positioned in the tops of the slots. A pair of arms 41 is then applied to the chair, the forward ends of the arms being provided with recesses 42 on their undersides which will receive the upper ends of the front legs. In applying the arms each arm has its recess 42 posltloned over the upper end of its forward leg. It is then forced downwardly onto the upper end" of the forward leg and during its downwardmovement it drives the wedge 40 home in the slot, expanding the upper end of the forward leg against the sides of the recess, thus forming a rigid permanent connection between the tops of the front legs and the aims without requiring the application of g ue. V

A In the rear end of each arm there is formed a squared slot 43 adapted to receive a nut 44. By virtue of the fact that the slot is squared on receiving the nut the slot will hold the nut against rotation therein, as clearly shown in Figure 6. Bolts 45, having pointed ends 46, are then driven through the back legs into the rear ends of the arms. The point 46 facilitates the bolt entering the nut and on tightening the bolt the arms will be firmly fastened to the back legs. I

A feature of the improved construction is as follows. While the arms employed may be counter-parts I prefer to have them duplicates of each other so that either arm may be used on" either side of the chair. In so doing the rear end of each arm is arranged at exactly right angles to its length and in adoptingv such a construction the forward faces of the back legs 22 and 23' are soformed as to provide surfaces at right angles to the line joining the center ofv the back leg with the center of its respective front leg. The back legs may be formed throughout their. entire lengths with the surface so arranged, or small recesses may be formed in. the forward faces of the back legs which will pre-. sent such surfaces. In this way either arm may be applied to either back. leg and serve to connect the back leg with its respective front leg.

. It will be readily appreciated, however,

that featu res of-the invention are. not re stricted to the use of'duplicatearms but CfJHItGd-Pfllt arms may be employed if desire It will be readily appreciated that the im proved chair enables a manufacturer to make up a stock of seat frames, all of which can be alike. He can keep in stock also various forms ofv back leg structures. He can also keep instock various'forms of front legs andvarious forms of arms On receiving an order he selects the required number of seat frames, the desired shape of back leg structure, the desired shape of front leg, and the desired arm, and easily and quickly assembles these parts. By leaving the various parts in un-assembled condition a large number of parts can be stored in a small amount of space. The improved chair also lends itself to shipping, wherein the various parts can be shipped -in-a knocked down conditionrequiring a minimum amount of space and on reaching the destination the various parts can be set up without requiring the application of glue. i

Various changes maybe made. in the details of construction without departing from the spirit or scope of the invention as-defined by the appended claim.

I claimz' An assembliable chair construction comprising a seat frame having connected sides, front and back, the. ends of the sides, front and back being spaced to provide recesses in the corners of the seat frame, a pair of back legs receivable in the recesses in the rear corners of the seat frame, upwardly directed wedges on the forward sides of the back legs,

the rear ends of the sldes having comp1e-' mentary sockets adapted to receive the a cross member connecting the back arranged to assist in supporting the the wedges and wedges, legs and back of the seat frame when sockets are in engagement, a pair of front at the front legs receivable in the recesses corners of the seat frame, means for fastening the front legs to the seat frame, arms carried by the front legs, and means for detachably connecting the rear ends of the arms to the back legs.

In testimony whereof I have signed my name to this specification.

. HARRY SISKIN.
