CAR-CHAIR.

SPECIFICATION forming part of Letters Patent No. 770,161, dated September 13, 1904.

Application filed January 2, 1904;.

T ml] whom it may concern:

Be it known that I, GEORGE W. OHAuBuRs,a citizen of the United States, residing at Newark, in the countyof Licking and State of Ohio, have invented certain new and useful Improvements in Oar-Chairs, of which the following is a specification.

This invention relates to new and novel improvements in car-chairs of the reversibleback type, and aims more especially to provide an improved form of operating means whereby the back of the chair is adapted to be reversed.

Further, the invention provides a peculiar manner of mounting the chair-seat and actuating means for simultaneously operating the seat and back, so that the position of the seat is adjusted relative to the position of the back when the latter is moved into either of its reversed positions.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and drawings hereto attached.

Vhile the essential and characteristic featu res of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side view showing the back disposed in one of its reversed positions. Fig. 2 is a view similar to Fig. 1, the position of the back being opposite that shown in Fig. 1. Fig. 3 is a rear elevation. Fig. 4 is a detail perspective view of the upper part of the end plate and the back-lever. Fig. 5 is a detail view of the end plate and seat, showing particularly the form of the shifting-lever.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by same reference characters.

In the drawings, 1 designates the back of the chair; 2, the seat, the back and seat being of any suitable cushion type found desirable, the exact form of same being non-essential to the practical embodiment of the invention. The chair is supported on legs 3, which are Serial No. 187,552. (No model.)

connected together by cross-bars 1, the lowermost of said cross-bars having their ends received in sockets 5, formed upon the inner sides of the legs 3, the uppermost of the crossbars resting in angular seats 6, disposed at the upper portion of the legs 3. The legs are cast of integral formation in the usual manner. Secured to the end portions of the upper cross-bars 4:, carried by the legs 3 of the chair, are end plates 7, said end plates being provided with corresponding sockets 8, which receive the end portions of the cross-bars 4; in

a manner readily apparent. The seat 2 is supported upon the end plates 7, the said end plates having cam enlargements 9 upon the upper front and rear portions, on which enlargements seat 2 directly rests. Upon the under side of the seat 2 are secured plates 10,

provided with segments 11 at the end portions thereof, which segments rest upon the cam enlargements 9 of the end plates 7, and intermediate the segments 11 are located bosses 12, which are integrally formed with the plates and utilized in a manner which will more fully appear hereinafter. The means for mounting the back 1 of the chair upon the seat consists, essentially, of a plurality of lazy-tong levers arranged in seats which for purposes of the description will be designated a a and b 7). The levers a a and b b are connected together at corresponding end portions, the opposite ends of the levers Z) 7) being secured upon the outer side of the end plates 7. One of the levers b 7) is secured to the adjacent end plate by a pivoted fastening 13, the other lever having its end secured to the end plate by a pin-and-slot connection 14.

The back 1 of the chair is secured to back-levers 15, which levers are carried by the lazytong levers a a and b 6. Either of the backlevers 15 is connected to corresponding ends of the lazy-tong levers a a, said back-levers being pivoted at their lower ends to one of the levers a a, as shown at 16, the other of the levers a a being provided with a pin 17,

which is received by a curved slot 18, provided in the back-levers. The seat 2 is operated by means of shifting-levers 19, pivotedintermediate their ends to the plates-7, the points of pivotal connection being designated 20. The lower ends of the levers 19 are provided with longitudinal slots 21, and said slots receive a pin 22, extended from the lazy-tong levers. The pin 22, if desirable, may constitute the pivotal connection of the lazy-tong levers a a, as shown. The shifting-levers are disposed upon the inner side of the end plates 7 and are provided at their upper ends with laterally-extendinglugs 23,which are received by the recessed bosses 12, establishing the connection between the seat and the back-operating means.

It will be noted that movement of the back 1 causes actuation of the lazy-tong levers a a and 7) b and that movement of the levers a a imparts a shifting movement to the levers 19. The shifting-levers 19 when moved as above described throw the seat either forwardly or rearwardly, as the case may be, and through the medium of the cam enlargements 9 the seat is disposed in a somewhat inclined positions of service.

tion, which position constitutes its normal disposal relative to the back 1 under all condi- The movement of the backlevers 15 is limited by lugs 24, projected from the outer side of the end plates 7, said lugs 24 forming stop means, bracing the back, as will be readily understood.

The weight of the seat 2 to a certain extent cooperates with the shifting-levers 19 to hold the back 1 firmly in either of its reversed positions, its function being performed because of the pressure of the seat upon the upper ends of the levers. To dispose the lazytong levers and other adjacent mechanism out of view, an end plate 25 is used, which is of any ornamental appearance and which is secured to the lugs 24, before mentioned, and other lugs, 26, projected from the end plates 7 by suitable fastening devices. The lower portions of the back-levers 15 are curved, as shown at 27, and the lower ends operated in rear of the plates 25.

Having thus described the invention, What is claimed as new is- 1. In a car-chair, the combination with supports, end plates carried by said supports, lazy-tong levers mounted upon the end plates, back-levers carried by the said lazy-tong levers, a seat, and connecting means between the lazy-tong levers and the seat.

2. In a car-chair, the combination with supports, end plates carried by said supports,lazy tong levers disposed upon the end plates, a

back, back-levers pivoted to the lazy-tonglevers aforesaid, a movable seat, and connecting means between the laZy-tonglevers and the seat for simultaneous operation of the same.

3. In a car-seat, the combination with a support, a pair of lazy-tong levers carried by said support, a back-lever pivoted at its lower end to one of the lazy-tong levers, and a connection between the other of the lazy-tong levers and the said baclolever.

4:. In a car-chair,the combination with a sup' port, a plurality of lazy-tong levers carried by said support, aback-lever pivoted at its lower end to one of the lazy-tong levers, and a loose connection between the back-lever and other of the lazy-tong levers.

5. In a car-chair, the combination with supports, end plates mounted upon the supports, lazy-tong levers disposed upon the end plates, back-levers pivotally supported relative to the lazy-tong levers, a seat resting upon the end plates, and shifting-levers pivoted intermediate their ends and connected at opposite ends to the seat and lazy-tong levers respectively.

6. In a car-chair, the combination with supports, end plates disposed upon said supports, lazy-tong levers mounted upon the end plates, back-levers pivoted at their lower ends to corresponding lazy-tong levers and having a pinand-slot connection intermediate their ends with other corresponding lazy-tong levers, the end plate being provided with cam enlargements, a seat resting on the cam enlargements of the end plates, shifting-levers pivoted intermediate their ends to the end plates and connected at their upper ends to the seat, the said shifting-levers having a pin-and-slot connection at their lower ends with the lazytong levers, whereby actuation of the backlevers causes simultaneous movement of the seat upon the end plates.

7. In a car-chair, the combination of a support, a plurality of lazy-tong levers carried by said support, a back-lever pivoted at its lower end to one of the lazy-tong levers, and a pin-and-slot connection connecting the backlever at a point between its ends with another of the lazy-tong levers.

In testimony whereof I afiix my signature in presence of two witnesses.
