Application filed Kay 31, 1916.

y v To all whom it may concern:

a use the same.

Be it known that I, D}; Varr lnrrnn, a citizen of the United States, residing at the town of New Milford, county of Litchfield, State of Connecticut, have invented certain new and useful Improvements in Adjustable Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and My invention relates to adjustable chairs, but more particularly has reference to a chair of this description especially adapted andv constructed for the purpose of utilizing what is known as a bustle back,

In Letters Patent No. 1,125,167, issued to me- Jan. 19,1915, I showed and described an adjustable chair equipped with the usual upholstery, and in which the lower edge of the chair back always swung above the rear edge of. the chair seat, but .I found that the,

construction of this chair was not at all adaptedfor the use of a bustle back, because the upholstery would become crushed and worn by reason of the fact that the lower portion of the back always swung above the rear portion of the seat.

The object of the present improvement is to provide a chair whose adjustmentsmay be made not only without crushing, or, in fact, contacting adjacent upholstered portions, but also without leaving any gap between theback and seat such as would permit of, the insertion or pinching of the clothing of'theoccupant of the chair.

f aFurtherobjects ofmy invention will appear from the description hereinafter given,

' and from theaccompanying drawings which illustrate a preferred embodin'lent of my in-' vention and In which- Figure 1 isa side elevation partly in section ofmy improved chairwith the parts in their normal position with the chair back in its comparatively vertical adjustment, Fig. 2 is a similar view showing the position that the parts assume" when the chair back is lowered so as to adapt the chair for the reclining of the occupant, and Fig. 3 isa front elevation of the chair, .1

Similar numerals of r ference denote like parts in theseveral figures of the drawing.

,lie the stationary frame of the-chair and 2 the seat having in its forward lower edge a jog 3 which rests loosely on a cross bar 4 of the chair frame, so that said seat is capa Specification of Letters Patent.

level of the seat, and 11 are links whose ex tren'lities are pivoted respectively to the ends of the extension and to the opposite side walls of the seat frame. It will, of course, be understood that these links connect the back with the seat at opposite sides, although 1' have only shown one of these links in the drawings. I

12 is a coil spring whose extremities are connected res )ectively with the back of the frame and with the lower part ofthe seat, the function of this spring being to assist in returning the parts to normal position,

and while this spring is not a feature that is essential to my invention, I ]')refe1.' to use it. 1

13 is the upholstery at the u Jper part of the back and ll is the upholstery at the lower portion of the back which protrudes very much after the fashion of a bustle, and chairs having this sort of upholstery are, therefore, known as bustle back chairs.

This upholstery l4 gradually decreases. in

thickness and is the thinnest at or about the point where the rear edge of the chair seat upholstery meets the lower edge of the bus tle portion 14:, and when the back of the chair is swung rearwardly the rear edge of the seat will be swung upwardly while at the same time the lower portion of the back will be swung both upwardly and rearwardly, the upward swing of this portion of the-back enabling the swinging moveniients 1 of the seat and back to be effected without any gap therebetweei'rwhile the rearward swinging movement of the back constantly removes the bustle, upholstery 1i from contact with the upholstery of the seat, so that the ad an tages of a bustle back are obtained and the adjustments made without the forn'lation of any gap between the rear edge of the seat and the back and also without any crushing or friction between the upholstery.

Secured to the underside of the seat frame a UNITED far- E OFFICE;

are cross bars 15 which project laterally from said frame and abut against cleats 16 that are secured to the frame of the chair when said seat has reached a horizontal position, these cleats being secured to the inside of the chair frame at opposite sides.

Any suitable means may be employed for locking the seat and back in their adjusted positions, a very simple embodiment of which consists of a bracket 17 having an elongated slot 18, which bracket is secured to the side of the seat, a short bolt 19 with a head 20 being so located with respect to this bracket that the bolt extends through the slot 18 while the head is in the immediate rear of the bracket, the bolt furthermore extending through an opening in the side of the frame 1 and terminating in a threaded portion, so that by driving a thumb nut 21 on this threaded portion and against the face of any suitable striker plate 22 secured to the side of the frame 1, the parts may be drawn together so as to lock the seat and consequently the chair back in any suitable adjusted position. Whenever the back is in its normal or upright position the lower outer edge of the extension 10 will abut against a cross piece 23 which forms a part of the chair frame and thereby prevent any further inward swing of the chair back.

For the further comfort of the user of the chair I have provided an adjustable foot rest, which consists of the usual footboard 24 that is hinged at 29 to the end of a platform 25 the rear portion of which latter extends within the frame of the seat and rests upon a cross piece 26 forming a part of said seat frame, any suitable pin 27 extending through this platform 25 in the immediate rear ofthe cross piece 26 to prevent the withdrawal of the platform. The platform extends through an elongated opening 28 in the front part of the frame 1 so as to be capable of vertical movements within certain limits.

A leg support 30 is pivotally connected to the part 24 by means of a link 31, one of these links being at each side of said support and'when in use this leg support at its free end rests upon the seat as shown at Fig. 2.

By swinging the leg support 30 forward the parts will assume the position shown in dotted lines so that theunderside of the leg support may serve as a support for the soles of the feet, and in this connection it will be noted that one face of the support 30 can serve as a support for the feet while the other face can serve as a support for the legs of the occupant of the chair, thus pre- Gopies oi this patent may be obtained for five cents each. by addressing the Washington, D. 0.

venting any dirt from the soles of the shoes soiling the legs of the trousers.

From the foregoing it will be readily understood that the pivotal point of the back of the chair is below the horizontal level of the chair seat, and since the extension 10 of the chair back is below this seat and is connected thereto by means of the link 11, it will be readily understood that the operation of my new improved chair in its adjustments can be effected without leaving any gap between the seat and the back and without injury to the upholstery in the slightest degree. Also, when the foot rest is not desired the part 24 may be swung to horizontal position and the part 30 allowed to lie flat against the platform 25, whereupon the entire foot rest structure may be pushed within the chair frame so that no part of the same except the rest 24 can be seen, this rest then appearing flat up against the seat frame as shown at Fig. 1.' Y

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

'1. In a chair, the'combination of a stationary frame, a seat pivotally connected at its front edge to the front of said frame and capable of swinging movements from said pivotal point, integral cross bars carried by said seat and having their; ends extending beyond the respective seat sides,

and integral cleats common to the cross bars I seat, a. bar pivoted at one end to the seat and having its other end slotted, a bolt con-' nected to the frame and extending through the slot of said-bar and having a head engaging the bar, and a'nut on the bolt for engaging the frame whereby to bind the bar against the frame.

3. In a chair, a frame, a seat pivoted at its front to the frame, a back pivoted to the frame, links pivoted to the back and seat, a bar pivoted at one end to the seat, and means to clamp the bar against the frame to lock same.

In testimony whereof I aifix my signature in presence of witnesses.
