To all whom it 'may concern:

Be it known that I,`FRANH E. BARNioKLE, a citizen of the' United States', residing `at Rochester, county of Stratford, and State of New Hampshire, have inventedv an Improvement in Reclining Attachments for Chairs, of which the following description, iii-cona specitication, like letters onV the drawing V a` novel .attachment4 for chairs which will firmly support an ordinary chair iii-a reclinf4 ing position. The device is arranged to `be attached to any chair, and whenV so attached a person sitting in the cliairmay v tilt thechair back and the chair ,will` be firmly snp ported in its tilted position. 1 5

I will first describe one embodiment of my invention and then point out`the novel fea-` tures thereof in the appended claims.

In the drawings, Figurefl is a perspective view of a chair havingmy-attachment apf plied thereto, said view showing` the chair in tilted position; Fig. 2 shows the `position of the attachment when it isfnot in use;` Figs.

.3 and v4 are detail views of thehinge by which the attachment is secured to the chair. Fig. 5 isa plan view of the `rest, 17 showing a portion of the `frame fto `which the rest, is secured.

My improved `attachment ycomprises the brace 3 which is arranged to be hinged to the back of the chair. This bracey carries two separate rests which are adapted torest "on Y the floor when the attachment is in use. In

the preferred embodimentof my invention this brace is formed Vfrom a piece ofwire bent to constitute the two side arms 4 which are connected by the` cross portion 5.

Attached `to the `upper end on each Aside arm 4 is a hinge member 6 which is hinged to a coinplemental hinge member `7. The

hinge member 7 is provided with the body 8 that is adapted to be Screwed to the back of the chair, as shown in Figs. 1 and 2. This' hinge member 7 has the two ears 9 between which is received the ear 10 on the hinge member 6, said ears being connected by the usual pintle pin 11. v To stiienand strengthen the hinge `member 7 I form it4 with the two stitfening flanges 12 one on either side thereof between which one of the screws 13 may be received. Said hinge member 7 is also provided with the shoulder or flange 14 .Y which coperates with the shoulders 15 `on the member 6 to limit the swinging move nient of the brace 3. I have shown the arms 4 of the brace as screw-threaded into the hinge member 6, although said arms might .beconnected to said hinge members in any Vsuitable way without departing from the invention.

. The brace sustains two rests 17 which are preferably made of rubber Or some other materialA which will have good frictional engagement with the floor. The advantage of as each having the open slot 18 in which the rod or wire formingA the brace is received,

vsaid shoes being retained in place by one or more proj ections or buttons 19 formed on the `rest or shoe above the wire. I prefer to place these shoes at the corners of the brace., that is, at the ends of the cross piece `5, as shown in the drawings, because when said shoes are thus located they embrace both the lower portiono'f the upright arms and the end portions vof the cross piece 5, and thus they are firmly held` on the brace and prevented y from turning thereon. invention, however, 'is.notlimited to placing them in this particular position.

. Inapplying the device to a chair the attachment will be placed with the rests' on `the `looradjacent to the rear legs of the chair and the two hinge members will then be screwed to the chair at the proper point. Whenever it is desired to tilt back in the chair the brace maybe swung backwardly as faras the stop 14 will permit and held in this position while the chair is tilted until the rests or shoes` are brought against the floor. The brace will then firmly maintain the chair in such position so long as the chair is occupied.

'By using a brace of the shape shown,

which has two rests thereon separated from each other avery tirm bearing is provided for the chair and all danger of the chair tipping sidewise is prevented.

It is sometimes desirable to provide for tilting the chair to a greater or less extent, and to permit this, I have provided my device with adjustable stops which limit the swingingmovement of the brace. For this purpose, I have herein shown set screws 20 threaded into the stop or flange 14 so that l adapted to engage the shoulder or abutment by setting up these screws more or less the distance through which the brace may be swung can be varied and thus the angle to which the chair can be tilted.

I have also shown a cord in the form of a chain 22 which is attached at one end to the center of the cross piece 5as at 23, and the other end of which may be secured to the bottom of the chair beneath the seat 24. This chain prevents the rear legs of the chair from slipping forwardly on the floor. It is not essential to my invention that this chain be employed, however.

My attachment is so constructed that when the chair stands upright it will drop by its own weight into the position shown in Fig. 2, and in such position is entirely out of the way and does notinterfere with any ordinary use to which the chair may be put.

In the preferred embodiment of the invention the brace is so shaped that when it is folded, the rests 17 lie against the chair legs, but the outer edges of said rests do not project beyond the outer faces of the chair legs. Said rests, therefore, serve to prevent the brace from injuring or marring the chair when the brace is folded.

I have illustrated herein one embodiment only of my invention and have not attempted to show all forms in which it may be made.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

1. An attachment for chairs comprising a brace made from a rod bent into U-shape and having at the end of each arm a hinge member provided with an abutment face or shoulder 15, a complemental hinge member pivoted to each of the lirst-named hinge members, means to secure each complemental hinge member to the back of a chair, and an adjustable stop screw carried by each complemental hinge member and face of the other hinge member thereby to limit backward swinging movement of the brace.

2. The combination with a chair, of a brace hinged to the back side of the chair, said brace comprising two connected side arms, a hinge member G at the upper end of each arm, a complemental hinge member pivoted to each hinge member 6, each hinge member T having a body portion for attachment to the chair and strengthening ribs connected by the transverse flange 14 and a stop screw carried by said flange and adapted to engage the hinge member to limit the backward swinging movement of the brace.

The combination with a chair, of a brace hinged to the back side of the chair, said brace comprising two parallel side arms 4L connected at their lower extremities by a cross piece 5, a rest at each end of the cross piece, each rest having an open slot to receive the angle of the brace, and projections to overlie the brace at the angle and retain the rest in position.

Ll. The combination with a chair, of a brace hinged to the back side of the chair, said brace comprising two connected side arms, a hinge member 6 at the upper end of each arm, each hinge member having the shoulder 15, a complemental hinge member 7 pivoted to each hinge member 6, each complemental hinge member having a body portion for attachment to the chair and a transverse flange, and stop screws :uljustably mounted in said flange and adapted to engage said shoulder 15 for limiting the back ward swinging movement of the brace.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
