WALTER E. CAMERON, OF TUNTON, MASSACHUSETTS.

Lenen Patent No. 105,903, dated August 2. 1 870.

The Schedule -refeixed to in these Letters Patent and making part ,ol the lame VBe it known that I, WALTER E. CAMERON, of Taunton, in `the county of Bristol and in the State of Massachusetts, have Yinventedv certain new and useful Improvements in Folding Chairs; and I' do hereby vdeclaretbat the following is `a full, clear, and exact description thereof', reference being-hadto'the acl companying drawing, and to the lettersof reference marked thereon, in-which'drawing- VFigure 1 represents a side elevation ofthe chair, as

arranged for use;

Figure 2, a side elevation as folded up;

Figure 3, a plan view of 'the bottom; and

Figure 4, avertical section on the' line :c x of fig. 3. Letters'of like kinds denote similar parts in each figure.-

` The objectot' my invention is a chair `which shall be elegantinfornn'strong and durable in construc-.

tion, and 'convenient in use, and yet'capable of being folded into asmall and eompactcompnss, for purposes of packing and storage; and

v'lhe naturepfthe invention consists in-the peculiar y devices employedtoeiiect the above named object,

and'in the arrangement of such devices..

f In the drawing- Arepresents the .chair` having a back, B, tothe lower part of the front of which is hinged the seat C, which, in turn, is provided with the arms D, pivoted at their rear ends to the side pieces of the back ,13, and at their fr ont endsjto the standards E, the upper' ends of which enter the respective arms, and the lower ends are pivoted upon the side pieces ot the seatC. i

, The rear legs `F of the chairare connected together by a rail, Cr, which is hingeduponthe top to the lower side of thebottom rail of the back B. The-iront legs H areconnected together in like manner, by'a rail, J,.which is hinged upoun its rear to the rear side of the front rail of the seat C.

vThe center of the front of the rail Gr is provided with a stationary hook, K, and the rail J is provided y .inthe vsame way with a similar hook, K.

A lock-bar, L, extends 'longitudinally across the lunder side of the seat C, passing in suitable grooves in the lfront and rear rails of the same, and has at the front end a rectangular hook, M, and at the rear end a similar hook, M', so arranged that, when tumed down, these hooks lock under"- the hooksK and K'.

A plate, N, secured to the under side of the front rail of the' seat C, over the lock-bar, andl near the hook M,'and a plate, O, secured in like manner tothe -under sideof the rear rail of the seat C,.over the bar and near its hook, prevent said bar from longitudinaly movement.

A strap, P,secured to the under side of the rear rail of the seat C, and thence passingl through the upper part of the bottomV rail -of the backB, and down into the rail G, is there fastened firmly'.

These parte thus namedconstitute the materialportions of the complete chair, and have no novelty in construction, except as hereinafter mentioned.

The. standards'E, of the form shown in figs. 1,2, and 4, have a shoulder, a, which, when thechaii'is in position for use, rests against the under sideof the..

arm D, and serves to brace andsnpport saidarm.

The hooks M, to the lock-bar L, extend outward and forward in similar corresponding plaues,`as do also the hooks K ,and K. The hinges used are the ordinary door-bolts.

When the chair is in position for use, it is unlocked and folded up in the following manner:

The front hook M is turned by hand one-quarter turn to the left, which unlocks the lock-bar L from the hooks K and K'. The front of the seat C is then` raised, and Aturned up against the back B. This movement of the seat also turns the rear legs F up against the rear side of the back B, by means of the draft upon the strap P, and pushes the arms D up in line with said back. 'At the same time the frontlegs H fallby their own weight against the under side of the seat C, and the whole chair is thus-folded up at 'once into a portable and secure form, as shown in iig. 2.

Having thus set outA the nature, description, and method of operation of my device,

What I claim as my invention therein, is-

1. The lock-bar L, provided with the hooks M and M', in combination with the hooks K and K', when constructed and arranged substantially as described and shown, and as andfor the purposes set forth.

2. The strap P, in combination with the seat C and the legs F, when constructed and arranged substantially-as described and shown, and as and for the purposes set forth.

3. The arrangement of the standard E, provided with the shoulders af, the arms D, the seat C, folding legs F-H, and the-back B, when constructed substantially as described and shown, and as and for the purposes setjorth. `4. The arrangement of the back B, the seat C, the legs F and TI, thev rails G and J, andv the strap P, when constructed substantially as described and shown, and as and for the purposes set forth.

, In" testimony that I claim th e foregoing, I have hereunto set my hand this day of July, 1870.
