Description

abated @man f @liw CARL DIETERICILOF ROSLINDALE, (WEST ROXBURY,) MASSACIIU- .SETTS Letters PatentNo. 88,776, dated April 13, 1869.

The Schedule referred to in these Letters Patent and making part of the sama.

To all persons to 'whom these presents may come:

Be it known that I, CARL DIETERICH, of Roslindale, of the townof W'est Roxbury, of the county 'of Norfolk, and State of Massachusetts, have invented a new and useful Improvement in Folding-Chairs; and do hereby declarethe saine to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is a side elevation,

Figure 2, a front View,` and Y y Figure 3, a vertical section of one of my chairs as unfolded, or with its parts in positions for a person to sit upon the seat.

Figure 4 denotes a front elevation, and

Figure 5, an edge View of the chair in a folded state.

In this chair, the legs and the side-bars of the back are formed by four levers, or bars, A A', B B'.

Each of the shorter levers, B or B', covers one of the back levers, A or A', and the two are connected, near the crossing, by a joint-pin, or screw, et, going through an ear, or short arm, b, projecting forward from the longer or back-bar lever, or from a platec, fastened to the outer side of the same.

The pair of back-bars, or levers A A', is connected by a series of bars, :l e fg, extending between and from one to the other of them, and being arranged in manner as represented.

The back, h, is secured to the upper two of such bars, and also to the levers A A.

Furthermore, the pair of shorter levers, B B', is connected by two bars, i k, going from one to the other' of them. p

There is an arm-rest, or iexile band, E, fastened to the upper part of each shorter lever, and extended and secured to the longer lever, in manner as represented.v

`The seat, shown at F, is connected with each of the back-bars, or levers by means of one of two short bars,

G G, and by screws going through the said bar at its v is screwed into the seat. The other screw goes through the bar, and is screwed into lthe back-lever. In other words, each link-bar G is to be pivoted both to the seat and to the back-bar.

Theseat is also provided with two hooks, or stops, Z I, to hook, or bear against studs m m, (projecting inward from the shorter levers B B,) when the chair is in an unfolded state, or its parts in the positions as' indicated in figs. 1, 2, and 3.

Vhen 4the chair is folded, the seat will be turned down into, .or about into, parallelism with the two sets y of levers, A A', B B', and the connections G G will overlap the studs m m. The ears, or arms b b will cause the shorter levers, when folded, to be in advance of and parallel, or nearly so, with the longer ones, in manner as shown in figs. 4 and 5. They also bring the pivots of the legs nearer the middle of the seat than would be the ease were 4they to go through the four levers,as in various other folding-chairs.

The peculiar advantage of the ears b b and the eonnection-bars G G, applied to and arranged with the seat and the two sets of levers, A A', B B', in manner as explained, is, that they enable such parts to be folded together in a better manner than they can be in various other chairs, and, besides, the connections G G allow the seat to rise upward, while being folded, from a horizontal to a vertical position.

IVhat I claim, in the above-described folding-chair, 1s-

rIhe arrt ngement and combination of the ears b b, and the connection-bars G G, with the seat and the two sets of levers, the said bars and ears being connected with the said seat and levers in manner substantially as described.

CARL DIETERICH. Witnesses:
