CHAIR.

Specification of Letters Patent.

Application filed January 2, 1912. Serial No. 669,053.

To all whom it may concern:

Be it known that I, ROBERT S. CALnF, a citizen of the United States, and a resident of Keene, in the county of Cheshire and State of New Hampshire, have invented an Improvement in Chairs, of which the following description, in connection with the accompanying drawings, is a specification,

like characters on the drawings representing like parts.

This invention relates to chairs, either of the set up or knock down type, and to the method of forming the seat thereof.

In order that the principle of the inve1rtion may be readily understood, I have disclosed a single type thereof in the accompanying drawing and the best manner known to me for carrying out the method.

In the drawing-Figure 1 is a plan view of the upper surface of a chair seat constructed in accordance with my invention,

the corner uprights being represented in section; Fig. 2 represents the side and cross stretchers of a chair in their relation to the u ri hts and my method of a plying the P e; P

filling thereto; Fig. 3 is a-view similar to Fig. 2, but represents also the warp as applied to the side stret-chers and interwoven with the filling; Fig. 4 is a detail representing the preferred manner of uniting the adjacent ends of the filling into one continuous length; and Fig. 5 is a detail view in perspective representing one manner of securing an end of the warp.

In the weaving by hand of chair seats of the general type to which this invention more particularly relates, it has been customary heretofore first to apply the warp (that is to saythe material passing from side to side of the seat) and usually in a continuous piece. Thereafter the weft (the material extending from front to rear of the seat) has been inserted in short lengths. Chair seats to which this invention more particularly relates are generally formed of rat-an strips, which are received at the place of manufacture of the chair in varying lengths. Heretofore in applying the short lengths of the filling, it has been customary to wrap one end of a filling strand upon the under side of the seat about a convenient portion of the warp strands, and then interweave the filling with the already positioned warp strands passing the same from front to rear or vice versa a number oftimes deweft strand. Inasmuch as in such former method of weaving the only way of securing the final end of each filling strand has been to wrap the same about a convenient portion of the warp, and inasmuch as such Patented Sept. 10, 1912.

method of operation resulted in an unsightly 1 joint, it has been the practice always to have the final end of each filling strand terminate upon the under side of the chair seat and to secure it upon the under side of the warp. To do this, it is usually necessary to sacrifice more or less of the natural length of the strand. This has resulted in. a very substantial waste of material, thus increasing the cost of the chair. Moreover, in the type of chair to which my invention more par ticularly relates, it has been customary to make the filling lengths (that is to sayt-hat length of a filling strand that is embraced between the front and rear stretchers) twice as numerous as the warp lengths. Since therefore the filling lengths were put in singly, it will be apparent that the application of the filling to the chair seat consumed much more time than did the application of the warp.

In applying the seating to the chair in the method heretofore practised, the chair frame was suitably clamped in such manner that it might readily be inverted from time to time. The operative stood at the side of the chair so that the warp extended from him. In this position, he was greatly hampered in his work if the chair were provided with arms.

It will be apparent that in the method In the practice of my invention, I connect separate strands of material, preferably ratan, into one continuous length by suitablysplicing the ends. I connect one end of such continuous strand in any suitable manner, as, for example, to either the front or the rear stretcher and then wrap such continuous strand about the frame of manner as not to be interfered with by the arms if such be provided. The final end of the continuous strand may be secured in any suitable manner. It willthus be apthe seat from frontto rear,the operative standing at the front of the chair in such "j to receive the lower side rungs or stretchers, sockets to recelve the arms, and other sock- 3 parent that the ratan so applied to the seat frame is self-sustaining. It will furthermore be apparent that there is no waste material. Further than this, since the amount of filling is substantially twice that of the warp, and inasmuch as the filling is applied in a continuous length by Wrapping the same in the manner described, much time is saved in this step of the operation. The filling is wrapped from front to rear with 'sufficient looseness to permit the interweaving or the warp. I11 those chairs, the seat whereof tapers from front to rear, the main portion only of the filling is thus wrapped in one continuous length, the edge portions of the filling being interwoven with the warp after the latter has been positioned. In the further practice of my invention and after the application of the main portion of the filling to the chair frame in the manner described, I then interweave the warp with the filling, and doing so preferably splice the ends of the natural lengths V of material to each other to constitute a .ings, the body of the chair may be of any rear uprights 2 preferably connected by alower cross stretcher (not shown) The said knock-down chair.

single continuous warp strand. Thereafter,

if the chair has a seat tapering from front to rear, I interweave short lengthsof filling at the edges of the main portion thereof to complete the chair seat.

Referring more particularly to the drawsuitable type, being either a set-up or a knock-down type, the same is composed preferably of front and rear sections, the

not herein necessary to disclose.

The rear section of the chair includes the uprights 2 may be provided with sockets 'ets to receive the side stretchers 4 of the seat ing of the warp therewith.

In the figures, I have represented my invention as applied to a knock-down chair having front uprights 1- and rear uprights 2. If the chair be of the.

sembled at the point of destination by applying the stretchers and the arms to the sockets provided therefor in the rear uprights 2. Herein I have termed the front and rear stretchers the cross stretchers.

The filling 6 (see particularly Fig. 2) is first passed about the front and rear stretchers of the chair seat as a continuous piece, the natural lengths of the material being fastened together in any suitable manner, as by wrapping the adjacent ends 7 and 8 of two pieces with a piece of wire 9 as shown most clearly in F ig. 4-. The first end of the continuous length may be secured in any suitable manner, as to the rear stretcher 5, and then is passed back and forth with adjacent portions of the material substantially in contact, the material being wrapped with sufficient slackness to permit the interweav- If the chair seat taper from front to rear, the continuous length of filling does not occupy the entire width of the chair seat at the front thereof. If desired, and preferably, the continuous length of filling begins at a point closely adjacent one of the rear uprights 2, as shown most clearly in Fig. 2. By applying the filling in the manner described I save much time and materially reduce the cost of the chair.

Referring more particularly to Figs. 1 and 3, the warp is applied to the chair seat and interwoven with the filling by first securing one end 10 of the warp 11 in any suitable manner, as by extending the same along one of the side stretchers 4, and then wrapping it about the adjacent front or rear stretcher, such, for example, as the rear stretcher 5 (see Fig. 5). Thereafter the warp is passed from one side stretcher to the opposite side stretcher, being interwoven with the filling, which in any suitable manner may be shedded to permit such The frame of the chair seat may be com-1 posed of a front stretcher 3 permanently: secured to the front uprights 1 and sideoperation. It is apparent that the end of the warp may be interwoven by hand with the filling, and if desired a needle may be attached thereto, or if preferred any suitable mechanism may be employed to elevate and depress in two series the portions of the filling. ,Preferably, the warp is composed of one continuous length consisting of the natural lengths of the material with the adjacent ends spliced together in the manner indicated in Fig. 4. The warp having been interwoven in the manner described, the final end thereof is secured in any suitable manner. If the chair seat be tapered as indicated in Figs. 1, 2 and 3, the lateral edge portions of the filling are in serted in

short lengths

12, 13, 14 and 15, the number of such lengths and their extent depending upon the shape of the chair.

It is apparent that in a chair thus constructed,the filling is self-sustained, and inasmuch as it is of substantially twice the extent of the warp, the chair is substantially twice as strong as in the old method of weaving. A great portion of the strain upon the strands in use may thus be borne by the filling.

In the application of the warp, it is passed from one side stretcher to the opposite side stretcher, and then it is preferably wrapped completely about such second side stretcher one or more times, as indicated at 16 in- Fig. 1. Thereafter it is returned to the first side stretcher and wrapped completely about the same one or more times, as indicated at 17 By thus wrapping the warp about the side stretchers, portions thereof are spaced apart, as clearly indicated in Figs. 1 and 3, to permit the proper interweaving of the warp with the filling.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.

1. As a new article of manufacture, a chair, the seat whereof is composed of front, rear and side stretchers suitably secured and filling and warp strands extending from front to rear and from side to side respectively and interwoven with each other, the main portion of the filling strands extending about the front and rear stretchers and constituting one continuous length composed of a series of strands having adjacent ends fastened together, the said warp strands passing about the side stretchers.

2. As a new article of manufacture, a chair, the seat whereof is composed of front, rear and side stretchers suitably secured, and filling and warp strands extending from front to rear and from side to side respectively and interwoven with each other, the main portion of the filling strands extending about the front and rear stretchers and constituting one continuous length composed of a series of strands having adjacent ends fastened together, said warp strands constituting one continuous length composed of a series of strands having their adjacent ends fastened together, the said warp strands passing about the side stretchers.

3. That method of forming a chair seat which consists in uniting together a number of strands to form a continuous filling, then wrapping said continuous filling about the front and rear cross stretchers, and then wrapping a warp strand about the side stretchers and interweaving said warp strand with the filling strand.

4. That method of forming a chair seat which consists in uniting together a number of strands to form a continuous filling, then securing one end of said strand directly to a part of the chair or seat frame, then wrapping said continuous fillingabout the front and rear stretchers, and then wrapping a warp strand about the side stretchers and interweaving said warp strand with the fill-' ing strand.

5. That method of forming a chair seat tapering from front to rear, which consists in uniting together a number of strands to form a continuous filling, then securing one end of said strand directly to a part of the chair or seat frame, then wrapping said continuous filling about the front and rear stretchers, then wrapping a warp strand about the side stretchers, and interweaving said warp strand with the filling strand, and finally in interweaving short filling sections with the warp between the edges of the applied continuous filling and the side stretchers.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
