GEORGE E. BOLTON, OF ST. LOUIS, MISSOURI.

PORTABLE ADJUSTABLE H EAD -REST.

CLZFCIFICATKQN forming part of Letters Patent No. Se l-{726, dated June 29, 1886 (.\'0 model.)

To aZZ whom it may concern:

1 Be it known that 1, Gnoncn E. DOLTON, of the city of St. Louis, State of Missouri, have made a certain new, useful, and valuable Iniprovementin Portable Adjustable Head-Rests, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, in which Figure 1v is a perspective view of front of head-rest raised; Fig. 2, rear view of same, Fig. 3, side elevation of head-rest, showing headrest as attached to the back of a car-seat ready for use; Fig. 4, side elevation of head rest, showing the head-rest turned back in another position from that shown in Fig. 3; and Fig. t shows in dotted lines the headrest dropped down in another position. Fig. 5 is a view showing the arms I) and E pivoted by a pin instead of a set-screw.

The object of my invention is to provide a portable device, which can be attached to the back of a chairor car-seat and adjusted in any position of rest for the head which the desires of comfort may dictate; and it consists, essentially, of a device for gripping the back of a chair or car-seat, a cushion or pad for the head i to rest upon, adjustably-connected arms piv oted to each other, so as to form three pivotal joints, by means of which the cushion and gripping device are connected together, and by means of which the cushion is adjusted to any desirable position of comfort and rest for the head. I have discovered that two pivotal joints or connections for adjustable arms connecting said cushion and gripping device together will not suffice to allow the adjustment of the cushion to varied positions of comfort and rest for the head, but with the addition of a third joint, providing a means of adjustment, the desired amount of play and opportunities for placing the cushion at varied and desired positions are obtained.

The construction of my invention is as follows: The device for gripping the back of the chair or car-seat is preferably in the shape of a gripping-spring made by bending a piece of suitable metal into a bow or U shape, and in practice I preferably make one of the ends of this U-shaped gripping device longer than the other, and provide this longer end with a thnmbscrcw and block, asshown in the drawings, but this is only my preferable construe tion, for I have found that a simple bow or U-shaped gripping device will hold the headrest mechanism in place on the back of a carseat by virtue. of the elasticity and grip of such U or bowshaped piece of metal when forced over the back of acar seat. This gripping device I have lettered Ain the drawings. Preferably I provide the grip A with a socket, a, into which a pin, B, with a rounded shank, is dropped. This pin Bis controlled in its position in socket a by means of a thumbscrew, 2). The head of the pin 13 is preferably broad and flat, and is provided with a hole, the object of which is to provide a means of connecting one end of a pivoted adjustable arm, 0, with the pin B and the gripping device A; and I preferably have the surface of the head of the pin B cogged, so that such surface maycome into play with a correspond ing surface in the end of arm Qenablingthesc two pieces to be held firmly in a desirable position, as hereinafter stated.

Thefirst of the pivoted arms I designate as O. This arm O, Iprefcrablyform oftwo pieces, as shown particularly by Fig. 2 of the drawings. The object of forming this arm, as there shown, in two pieces is to afford the op-- portunity for making a good pivotal connection with pin B, the lower ends of the pieces of arm G being preferably flat, and preferably having a coggcd face corresponding to the cogged surface at the head of pin I3, and provided with a hole corresponding to the hole in the head of pin B, by means of which the shank of the same tlinnibscrew passes through the lower ends of the pieces that form arm 0, and through the head of pin 13, thus forming a connection or joint between the head of the pin B and the lower part of arm G, which is a connection which may be regulated so as to be either a loose or pivotal conncction between pin B and arm 0, or a rigid connection between these two parts. The upper ends of the pieces forming arm 0 are pref erably broad and flat, and preferably provided with a cogged surface, for the purposes stated, and are also provided with holes, and between these upper ends of arms O a like end of arm I), which is also provided with a hole, and preferably cogged for the purposes stated, is placed, and an adjustable and plvotal connection orjoint, Y, is there formed between the arms and D by passing the shank of a'thumb screw through these openjustable connection or joint, Z, is formed between arms D and Eloy inserting the shank of a thumb-screw through the holes in the ends of pieces forming arm E, and through said end of arm D. I say this connection between arms D and E may be made by means of the shank of a tl'inmb'screw, but a thumbscrew to form this joint is hardly necessary, for it is advisable, generally speaking, to have this connection between the arms D and E a loose pivotal connection, it having been found in practice that it is almost never desirable to have that connection rigid.

It will readily be seen that my third pivotal ad nstable connection or j ointZ may be formed by dispensing with the rigid pieces forming arm E, and by pivoting the end of arm D directly to frame of cushion F; but the cmstruc- .tion shown is my preferable one.

My pivoted adjustable arms 0, D, and E, as also the rest of my device, excepting the cushlon-pad, are preferably made of metal.

My cushion F consists, essentially, of a back piece or frame-work to which the end of arm E not connected with arm D is rigidly attached, or into which arm D may be pivoted, as before stated. The face of cushion F is covered with some soft material for the head to'rest upon.

As a preferable addition to my device, by means of a thumb-screw'I attach a pivoted arm, G, to my cushion F. This arm G is bent at its end 9 to form a side piece for cushion F, and the end 9 of arm G is padded.

The operation of my invention is as follows: The thumb-screws connecting arms 0, D, and E, and the cushion F and the grip A together being loosened, as is readily seen, my headrest can be dropped forward and down into the back of the seat and there adjusted in any position desirable. It can be dropped back into the positions shown in Fig. 4 of the drawings, to form arest in any suitable position for a person on a back seat, and with its peculiar facilities for adjustment my device can be used to rest the head of a child or of a tall grown person. When any desirable position has been reached, my device can be arrested in that position by tightening thumb-screws,- but, as previously stated, the thumb-screws connecting arm 0 to grip being tightened and the thumb-screws connecting arms 0 and D together being tightened, it is desirable not to tighten the thumbscrew connecting arm D and E together; but it is desirable to let this connection or joint between arms D and E, or between arm D and frame of cushion F, remain a loose connection. The attachment formed by the pivoted arm G and its padded end is of advantage in preventing the head from slipping from the cushion.

I am aware that a single arm pivoted to a head-rest and to an adjustable rod or fastening device,which is secured to the back of a chair is not new, and I do not desire to claim the same.

I amalso aware that portablehead-rests are described in Letters Patent No. 242,380, dated May 31, 1881, and I not desire to claim the same.

I claim- 1. In a portable adjustable head-rest, the combination of the arms 0 D, pivotally connected with each other, a head-rest, F, having a detachable arm, G, said rest being pivoted to the arm D, and a gripper, A, to which the arm 0 is adjustably pivoted, substantially as and for the purposes specified.

2. In a portable adjustable head-rest, the combination of the double bar 0, single bar D, and adjustable pin 13, pivotally connected by thumb-screws, and a head-rest, F, to which the bar D is pivotally connected, substantially as and for the purposes specified.

In testimony whereof I have affixed my signature, in presence of two witnesses, this 13th day of August, 1885.

GEORGE E. Dom-on.
