MARSENA BENEDICT, OF NEW YORK, N. Y.

SEAT.

SPECIFICATION forming part ofLetters Patent No. 337,364, dated March 9, 1886. Application filed June 21, 1885. Serial No. 110,051. (No model.)

To aZZ whom it may concern.-

- Be it known that I, MARsENA BENEDICT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Seats, of which the following is a specification, reference being had therein to the accompanying drawings.

My present invention relates to certain improvements on that for which Letters Patent No. 291,487 were granted to me under date of January 8, 1884 and it consists in a novel construction of the frame and webbing or'cloth which forms the seat, and a novel means for attaching them to each other for tightening the cloth or webbing when necessary, and for attaching the apparatus to seat-frames of different descriptions, as hereinafter more particularly described.

The accompanying drawings illustrate the construction,operatiomand application of my invention. 3

Figure 1 is a perspective view of the frame and the cloth or webbing which forms the seat proper, and which may be applied to the seatframe of a wagon, chair, piano-stool, or other suitable article. Fig. 2 is a plan view of the cloth or webbing when ready to be attached to the frame. Fig. 3 isa perspective view of the frame without the cloth or webbing,showing the manner ofattaching it to the seatframe of a chair or wagon. Fig. 4 is a top view of the same with the cloth or webbing in place and the seat in position flat down on the seat-frame. Fig. 5 is an edge View of Fig.3, with the frame resting flat down on the seat-frame. Fig. 61s a longitudinal vertical section taken in the line at :0 of Fig. 4. Fig. 7 is a transverse section taken in the line 3 y of Fig. 4.

The frame of theseat-proper is composed of two side bars, a rear bar, two strap-pieces,and a front rod. The side bars, A A, are made of metal, each bar having on its outer side a groove, a, running its entire length, and provided with a slot, 1), somewhat shorter than the groove. Near the rear endof each bar,on the inner side, is a lug, c, and on the extreme end of the bar is a semi-cylindrical notch, d. The rear bar, B, is made of wood, and theside bars are attached thereto by screws passed through the lugs c. The frontends of the bars 'A are attached by hinged joints to strap-pieces D, which are provided with eyes e, through I which pass the round ends of the front rod, E. On this rod E area number of cylindrical enlargements,from which extend teeth f, which serve the same purpose as buckles, which are used in connection with straps. The rod E may be placed under the seat-frame, if found necessary. The side bars, A A, being longer from the hinge than the strap-pieces D D, the

sidebars,A A.become,asit were,long arms of a lever, the strip pieces DD become short arms of a lever, and the pivots of the hinge forming the fulcrum. Thelarger portion of the frame being thrown upward, as shown in Fig. 3,the

power is applied at the point B, while the weight or resistance is distributed over the surfaceof the webin the form of tension, thereby alfording the required leverage to keep the web properly stretched.

. .The cloth or webbing G, to form the seat, is first cut in somewhat the form of a cross. The two side arms of this cross are turned in ward and securely stitched, so as to form side pockets, 9 g, and the top arm or rear end is turned inward about one-fourth of its length and stitched so as to form an end pocket, h, (all of said pockets being larger than the rods.)

The cloth or webbing thus arranged is attached to the frame, as follows: The sidepockets are passed through the slots 1), and rods 42 are-passed through them, said rods being larger than the width of the slots, and lying in the grooves a,'so as not to extend beyond the outer surface of the side bars. .EBy thus attaching the side-, edges ofthe cloth'or web and engaged by the buckles f, and the seat is complete.

The seat thus formed may be attached to a seat-frame of any suitable description by means of screws or bolts passed through the strappieces D. In Figs. 3, 5, and 6 it is shown as attached to a square frame, such as might be used for a chair or a wagonseat.

IOO

In my former patent it is necessary to have hooks or other means to hold the rear portion of the hinged seat in place when down. In the present invention when the seat is down flat, so that the side bars rest on the rear portions of the strap-pieces, the hinge-pivots are higher than the points of attachment of the front and rear lower edges, so that the strain is from two points below the level of said pivots and the seat is automatically held down in place thereby. When the web or cloth be comes loose from wear and use, the rear portion of the frame is raised to the position shown in Figs. 1 and 3, the cloth is stretched to the proper distance and re'engaged by the buckles, and the frame lowered again to the proper position. The bottom of the rear rod is on the same level with the web on the front, and the top of the rear. rod occupies a higher position than the level of the front, so that the portion of the web which reaches from the top of the rear rod forward to the seam at the foot of the inclined plane formed by the pocket becomes a cant-lever.

In sitting, the point of the hips (or more correctly speaking the point of the ischium) is farther forward and on a lower level than the base of the spine, so that a flat cnshionor a stuffed one that is highest in the middle affords no support for that portion of the trunk lying between these two points. This portion of the trunk includes the spinal column, which, not being supported by such cushions, the normal relative position of the vertebra is maintained by muscular effort, occasioning muscular weariness and nervous exhaustion.

By this construction of my invention theinclined plane formed by the upper surface of the pocket, extending from the rearrod to the line of stitching Q, constitutes a comfortable support for the portion of the body containing the base ofthe spinal column, and this incline of the plane being pliable it also adapts and adjusts itself to the particular form and size of each separate individual.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In a seat, the combination of side bars provided with longitudinal slots and grooves, a rear bar attached to said side bars, and a seat-frame supporting the side bars by means of hinge-joints, substantially as and for the purpose described.

2. In a seat, the combination of side bars provided-with longitudinal slots and grooves,

Y a rear bar attached to said side bars, a seat 3. In a seat, the combination of side bars provided with longitudinal slots and grooves, a rear bar attached to said side bars, and a .front rod or bar provided with buckles and joints, substantially as and for the purpose herein described.

4. A cloth or webbing provided with side pockets and a rear end pocket, in combination with a frame constructed as described, with longitudinal slots and grooves and with side rods, 2', rear end rod', J, front rod, E, and buckles f, carried by the front rod, substantially as and for the purpose herein described.-

5. A seat consisting of a hinged frame and a cloth or webbing carried thereby, said hinged frame having its front and rear edges below the level of the hinge-pivots when the cloth or webbing is in place'and the seat in position, whereby the parts are automatically held in place by the strain or line of draft being below the level of the hinge-pivots, substantially as herein described.

6. A seat consisting of a hinged frame and a cloth or webbing carried thereby. said cloth or webbing having a rear pocket forming an inclined plane for the support of the base of the spinal column, substantially as herein described.

7. A seat embodying in its structure a hinged frame, a cloth or webbing having a pocket formed in its rear edge, and a rod passing through the pocket for securing the cloth or webbing to the frame at that point, the whole being so arranged that the portion of the cloth or webbing which extends from said rod to the base of the pocket is an inclined plane, there by operating'to support the center of the span of the webbing and preventing the latter from sagging, substantially as shown and described.

8. In a seat, a frame divided into two parts, one longer than the. other, hinged together at such point that the distance from the point of division of the frame to the attachment of one edge of the web is greater than the distance from the point of division to the attachment of the opposite edge, for-the purpose of providing leverage forstraining the cloth, substantially as herein described.

In testimony whereof I afiix my signature in presence of two witnesses.
