COLLIGNON V. HATES. 913 �"This invention relates to chairs which fold up into a small space, whereby they are rendered much more convenient for transportation and storage than chairs of ordinary construction, and consista in the peculiar arrangement and combination of parts, as hereinaf ter more fully described. In the accompany- ing sheet of drawing, figure 1 represents a sida elevation of the chair, as when ready for use. Figure 2 shows the chair as folded up. Figure 3 is a backside elevation. Similar letters of reference indicate corresponding parts. A is the back, the sides of which extend to the floor and form the front legs, B B. C C are the back legs. D represents the seat, and A represents a brace in each side, which is pivoted to the front and back legs, as seen in the drawing. The seat is pivoted or jointed to the side pieces which form the back and front legs, as seen at /, and to the back or rear legs, as seen at g. These joints may be formed by short pivots or bolts, or by rods extendirig across from leg to leg of the chair, as may be deemed best. A suitable number of rounds, h, may connect the back legs, C, and also the front legs, B, together.
- * * it will be seen that when the seat is raised the upper ends of the
back legs (against which the back of the chair bears in supporting a weight on the chair) are thrown down, and the lower ends are thrown up, and the chair will fold together, as seen in figure 2, thus rendering the chair much more useful than ordinary chairs, as it may be laid away when not in use, and may be packed in boxes or in bundles, for transportation. * * * The ends of the back legs may be provided with pins, which shall enter holes in the back, where the bearing cornes, as at r, should it be considered best to do so." �His claims are : �" (1) The seat, D, pivoted to the front leg, B, and at its rear, and to the back legs, C, whereby the several parts are adapted to be folded together as herein shown and described, for the purpose specifled. (2) In combination with the above, the brace, E, arranged to operate substantially as described." �The defendant constructs and sells folding ehairs made in accord- anee with the letters patent No. 221,062, granted to him October 28, 1879. It is alleged that chairs so made infringe claim 1 of the plain- tiff's patent. It is plain that that claim relates to the pivoting together, in the manner shown, of the parts named in the claim, in such manner that the parts can fold together, and the chair become a folded chair. The parts named are the seat, D, the front legs, B, and the back legs, C. The side rail of the seat on each side is pivoted to the front leg at a point in such side rail intermediate between the front end and the rear end of such side rail, and at a point in such front leg intermediate between the top and the bottom of such front leg; and such side rail on each side is pivoted at its rear end to a point in the back leg near the upper end thereof. By raising such side rails towards the back of the chair, the upper ends of the back legs are v.8,no.l2— 58 ��� �
