llnirdv gister @met Mire.
FRANCIS M. HOLMES, OF BOSTON, MASSACHUSETTS.
Letters Potent No. 105,079, dated July 5, 1870.
The Schedule referred to in these Lettere Patent and mlaking part of the same To all persons to whom. these presents may come:`
Be it known that LFRANoIs M. HoLMEs, of Bos,- ton, in the county of Suffolk end'Steteof Massachusetts, have invented e new and useful Improvement in Folding Chairs; and do herebydeclare the sameto be fully described in the following specification, reference being hed to the accompanying drawing, ot ,which- Figure 1 is o. front elevation 'Figure 2, a. side view; und
Figure 3, a. vertical section of u folding chair provided with my invention. In carrying ont my present improvement the sent of' the .chair is to be hinged ton rung or bur firmly fastened to the upper arms 'of the shorter pair of the curved levers, the said' he1',with the two shorter levers :ind another hor or rung connecting them, composing a. rigid frame.
Then the seat is piroted to shorter levers, they are apt to become split or broken bythe strain ou the.
points, induced by a, person while sitting upon the seat. It is lvery objectionable, also, to hinge the sent to the tops of' the shorter levers. f
In this chair thelegs and the side bars of the buck are formedby four levers, A AB B. lEach of the Vshorter levers B B crosses one of the buck or longer .levers- A A', the two at the crossing being pivoted together or connected by tfulcrum or joint-pin-Ta, going through one and into the other, orth'rou'gh both,
, if preferable.
The shorter levers are arranged outside of the longer' levers, and are connected by two rungs or crossbars, b e.
The sent, shown et G,rests on and is hinged es represented at h', directly to the upper' rung or bor c such sent, whenihe chair is unfolded as exhibited in the drawing, also rests on` aroundV sul'iport-her or rung, e, whose lends are sustained hyprojec'tions ffextended from thelongcr levers, in manner us represented.
Furthermore, the two longer levers are connected, near their lower ends, hy means of e rung, g, and also at or nea-r their upper ends and middles hy two other rungs or hars, It t', fastened to projections k l k l extended` from suoli levers, the /who'le being :t1-ranged in manner as represented in the, drawing.
The two rungs, h t, compose part oi' the heck ijzunc, and muy be connected by bers or lframe-pieces m m.
The seat is furnished with one or more hooks, n, to extend from its reatr part, and hook upward around the middle rung e of the longer levers.
From thezihove it will be seen that, when the sent is horizonte-l, it will be supported Vby three rungs, und that. it has no direct pivotal Yconnection with either of of the levers, it being hinged to the frontonc ofthe said three rungs.
I claim- A foldiu, :,r-ch:iir, as mede with its sont C hinged to a. rung, c, rigidly fastened to the two shorter levers B B', :ind es having two` other seat-supportingrungs, et, arranged and applied to the longer levers, as described.
