HENRY S. HALE, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE HALE & KILBURN MANUFACTURING COMPANY, OF PENNSYLVANIA.

CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 475,109, dated May 17,1892.

Application filed June 5, 1891. Serial No. 395,224- (No model.)

September 9, 1890, granted to W. M. Norcross for an improvement in car-seats, and particularly to the means of supporting the reversible back to the main frame, and also to certain improvements in the foot-rests and v the locking devices for locking the seat-back in its reversed positions.

Referring to the drawings, Figure 1 is a sectional elevation on line 1 2 of Fig. 2 of a car-seat embodying my invention. Fig. 2 is a front sectional elevation of same on line 3 4 of Fig. 1. Fig. 3 is a sectional plan view through the seat-back on line 5 6. Fig. 4 is a side elevation of the hinge-arms removed from the seat-back. Fig. 5 is a front elevation of same. Fig. 6 is a sectional plan of the locking device on line 7 8 of Fig. 4; and Fig. 7 is a cross-section of the hinge-arms on line 9 10.

A is the main frame, and B B are the supporting guide-rails for the seat-support O, which is formed of metal having the lower cam-face 0 running upon the upper surfaces of the guide-rails B.

D is the seat-cushion, which rests upon the supports 0. By shifting the support 0 over its guides the seat is tilted at the same time that it is shifted in the well-known manner.

E is-the seat-back, and is hinged to the mainframe by hinge-arms F, each composed of parallel bars F and F which bars are hinged at the upper ends to the metal plate I on the ends of the seat-back, respectively, at t" and 2' and at the bottom to the main frame at f and f respectively. It will be observed that the bars cross each other, which has the effect of reversing the seat-back or turning it upside down, as is clearly set out in the aforesaid Letters Patent referred to.

In the said Letters Patent the bars F and F the bars F and F are formed with Webs or widened parts H, which lie flat against each other and never separate, and at this point form no opening through which the hand could be placed. The lower part of one of the arms-F, for instance-is extended and provided with a pin or projectionG, working in a slot g in the seat-supports C, by which the said seat and its supports are shifted upon the rails B in exact accordance with the manipulation of the seat-back. The upper ends of the bars F F are provided with holes f, and one 05 the other of these holes is brought into line with a bolt J on the plates I at the respective ends of the seat-back, so that the bolt may be passed into the said holes to lock the back and hinge-arm rigidly in position. In this construction it is notnecessary to lock the back to the main frame, since the locking of the hinge-arms to the seat-back prevents any movement of the seat-back with respect to'the main frame, owing to the peculiar cross connection of the two bars making up the hinge arms with the seat-back and main frame. The bolt J upon the outside of the seat is operated by a key-cylinder K, which may be drawn outward by the insertion and operation of the key. The bolt may be springactuated, if desired. The inner boltL is con- .nected through the seat-back with the keycylinder K, so that upon operating the keycylinder the one act simultaneously operates.

the bolt J and the bolt L,.liberating orlocking the seat-back to the hingearms at both ends of the seat.

M are the foot-rests, which, in place of being rigidly secured to the main frame A, as'

has been customary, are pivoted at N to said main frame and are free to be swung upward or downward, assuming either the position indicated in solid lines or the position indicated in dotted lines. Stops or projections m and m on the main frame act as supports for the free edge of the foot-rest when raised or lowered.

It will be observed that the foot-rest is formed of wood and the journals are upon the ends of the wood and formed integral with the body of the foot-rest. These journals are received in sockets cast upon the inner faces of the main frame. By this means the footrest can be turned out of the way when not desired for use, and the construction is particularly advantageous when it is desired to clean the car. As heretofore constructed, there was seldom room sufficient between the foot-rest and the floor of the car to permit the passage of a brush or broom for sweeping the car-floor under the seats. By my improvement the foot-rests may be turned up out of the way and give a large clearance for the passage of the broom or brush.

While I prefer the construction shown it is evident that the details may be modified in various ways, Without departing from the principles of my invention.

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

1. In a car-seat, the combination of a main frame, a reversible seat-back, hinge-arms for securing the seat-back to the main frame, a locking-bolt for locking one end of the seatback extending through to the opposite end of the seat-back so as to be'operated from said opposite end, a locking-bolt for said opposite end-of the seat-back, and aconnection between this bolt and the first-mentioned bolt, whereby the seat-back may be locked at both of its ends, and the locking-bolts may be simultaneously operated from one end of the seat-back.

2. In a car-seat, the combination of the main frame, a reversible seat-back, hinge-arms at each end of the seat-back, each composed of two bars hinged to the seat-back and to the main frame, but in which the hinge-points of the said bars at one end are reversed with respect to the hinge-points at the other end, each of said bars being provided with a locking-recess and a common locking device for simultaneously locking and unlocking the seat-back with respect to the locking recesses upon the corresponding bars of the hingearms at each end of the said seat-back. 4

3. In acar seat, the combination of the main frame, a reversible seat-back, and a hingearm between the main frame and seat-back, consisting of two bars hinged at one end to the seat-back and having their other ends'bent at an angle and crossed below the surface of the seat-cushion and hinged to themain frame and arranged at a distance apart throughout the distance above the seat-cushion, so that the said bars have a clearance between them at their upper portions, the hinge connections of the said bars with the main frame being reversed with respect to their hinge connections with the seat-back.

4. In a car-seat, the combination of the main frame and the reversible seat-back with hingearms F, consisting of two bars F and F respectively, hinged to the seat-back by hinges t" t and to the main frame by hingesff respectively, the said bars having their upper portions above the seat-cushion at all times separated by a space F and having their lower portions adjacent to the main frame bent at an angle to cross each other below the surface of the seat-cushion, so as to bring the hinges f f in the reversed order with respect to the hinges z" 2' 5. In a car-seat, the combination of the main frame, the reversible seat-back, and the hingearms connecting the seat-back to the main frame, said hinge-arms consisting of two crossbars hinged to the seat-back and also to the main frame and in which the said bars are provided with webs or flattened portions which lap over each other, so as to prevent apertures being formed between the said bars in reversing the seat-back.

In testimony of which invention I have hereunto set my hand.
