To all whom it may concern."

Be it known that 1, WILLIAM H. PARRY, a citizen of the United States, residing in the city of Kenosha, county of Kenosha, and State of Wisconsin, have invented oer tain new and useful Improvements in Folding Chairs, of which the following is a specification.

This invention relates to improvements in folding chairs and has among its salient objects to provide a construction which can be easily opened or closed, and which while relatively light is characterized by its ability to stand excessive weight or strains; to provide a construction of the character referred to which has a relatively wide base, 2'. e., the distance between the front and rear legs in extended position, whereby it is nontipping even though all the weight is ap plied to the front edge or the seat and none on the back edge; to provide a construction which may be tilted back by the user as are ordinary chairs without causing the chair to fold up and without straining the weaker connecting parts; to provide a construction in which the strain and weight is borne by the seat and legs instead oi 'by the back and pivotal connections; to rovide a construction which will open an close without any danger of binding, which canbe fielded that into a relatively smells ace and which'is not afiected in its operation by warping; to

rovide a construction which while embody mg the features and advantages above mentioned may nevertheless be built from short light scrap pieces of lumber which is an important commercial advantage in a device of this character; and in general to revide an improved construction of the c aracter referred to.

The invention consists in the matters hereinafter described and more particularly pointed out in the ap ended claims.

In the drawings i re 1 isa front elevation of the chair in olded position; Fig. 2 is an end elevation of the view in Fig. 1, with parts broken away, and other parts shown in dotted lines; Fig. 3 shows the chair in open position in full lines and in partly closed position in dotted lines; Fig. 4 is a fragmentary detail showing the manner of connecting the seat to-the side rails of the back frame.

Referring to the drawings-1 designates the back comprlsing side rails, the lower.

ends of which serve as braces for the back, transversely extending bars 1 and 1 and vertically extending slats 9' connected at their upper end lower ends to the trans verse bars 1' and 1".

2 designates the front legs and 3 the rear legs which are ivotally connected intermediate their en s by a main rung or dowel pin d. The lower ends of these legs are preferably beveled as shown in Fig. 3 so that the chair will be more efiectively braced against slipping and at the same time rest more firmly on the floor. purposes of added strength the front legs 2 are provided. with upper and lower rungs or dowels fi and 6 respectively.

The seat i comprises side bars 7' cross bars 7 and central slats 20. The side bars 7' or the seat have rearwardly extending extensions or lugs 10 which are pivotally secured to the side rails 9 in such a way that the seat is slightl spaced away at either side from the si e rails 9 to permit the seat to be opened and folded without binding. To this end brackets 11 are tastened as shown at it to the outer edges of the extensions 10. Each of these brackets is provided with an upstanding oflset ear 12 which is pivoted by a pin 13 to the inner face of the adjacent rail, 9.

The inneredges of the lugs 10 of the seat are pivotally connected by bolts 14: to the upper ends oi the front legs 2. In order that'the rear legs 3 may swing to folded position with the seat, short metal. links or straps 16 are pivoted as shownat 17 to the u tile side bars 7 of the seat, as shown at 18. These links 16 are merel connections for Sw nging the rear legs to c osed poslt on and are not intended to assist in support-111g the weight on the seat of the chair.

It will be noted that the side ra1ls 9 pro: ject some distance below the main body ot the back and at their lower ends are p1vot-' ally secured to ofiset link 21 by pins 19.

to the rear legs 3 so that they will swing the back member into alinement with the seat when the latter is folded. To prevent the link 21-from swinging too far when the chair is folded, ll provide short pins 21' secured to the rear legs. 3.

As will be seen in Figs. 1 and 2 the legs and seat lie between the side rails 9 of the The other end of the links 21 are pivoted- For per ends of the rear legs 3 and also to p
