HENRY S. HALE, OF PHILADELPHIA, PENNSYLVANIA.

CAR OR OTHER SEAT.

SPECIFICATION forming part of Letters Patent No. 417,823, dated December 24, 1889.

Application filed September 12, 1888. Serial No. 285,187. (No model.)

To all whom it may concern.-

Be it known that l, HENRY S. HALE, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Car or other Seats, (Case 13,) of which the following is a specification.

My invention has reference to car or other seats; and it consists in certain improvem ents, all of which are fully setforth in the following specification and shown in the accompanying drawings, which form part thereof.

The object of my invention is to provide a more suitable construction, whereby there are no projections or other objectionable obstructions upon the seat-arms upon which to catch and tear the clothes.

My object is also to provide amore perfect means of guiding and supporting the hingearms upon which the back is pivoted, and to give them a provision for variable throw to vary the adjustment of the seat-back.

My object is also to provide a durable connection between the two hinge-arms, whereby they move as a rigid structure.

In carrying out my invention I prefer to adapt it to car-seats having not only reversible backs, but also provided with shifting and tilting seat-cushions. However, this latter is not necessary to-my present invention. The main frame, at one or both ends, is provided with an arm-rest, furnished, preferably,

upon its under side with a continuous guide,

into which a projection from the hinge-arm extends, and by which it is guided throughout the entire throw and prevented from rubbing against the woodwork of the seat-arm. The ends of this guide maybe provided with one or more stops, on which suitable springcatches carried by the hinge-arm may catch to hold the hinge-arms in different adjustments, andbysuit-ablemechanism said catches at both ends of the seat maybe simultaneously operated from either end. These spring-catches may be locked by suitable locks carried by the hingearms, so as to prevent the seat-back being reversed without first operating the lock. I also connect the two pivothinged clearly shown in the drawings and fully described hereinafter.

In the drawings, Figure 1 is a side elevation of my improved seat. Fig. 2 is asectional elevation of same on line pg of Fig. Fig. 3 is a front elevation of my improved seat, with one-half in section on line so a: of Fig. 2. Fig.

hinge-arms, their connections, and catch-operating device. Fig. 5 is a sectional elevation of the lower part of the seat on line x m of Fig. 2, but with the hinge-arm raised to a vertical position. Fig. 6 is a sectional view through the hinge-arm, arm-rest, and guide, showinga suitable lock for securing the catch against movement. Fig. 7 is a perspective view of the locking-bolt removed; and Fig.8 is a perspective view of the lower end of one of the hinge-arms, showing the means for clamping the connecting-bar.

A is the main frame, having the legs D extending down to the fioor and formed at the upper part into the frames D, to which the hinge-arms are pivoted at c. The said frames D are also provided with the guides Gr, upon which the seat-supporting frames II rest and are shifted. The under or cam surfaces I of the frames l-l insure the tilting of the seat during the act of shifting.

F is the seat-cushion, which rests upon the frames H.

(l are the hingearms, pivoted, as before stated, to the frames D at c, and connected at their lower parts below the said fulcrum points 0 with the frames H by pins h. The upper ends of these hinge-arms are'pivoted to the seat-back B at b in any suitable manner. The lower ends of the hinge-arms are rigidly connected by a bar P, made rectangular in cross-section and received in sockets P, and clamped on its ends by caps P and clamping screws or bolts 1), as clearly shown in Figs. l and 8. By this construction both hinge-arms are required to move together, and much binding and jarring are obviated.

The frame A is provided with fixed armrests E, which are preferably curved upon their under side and provided with a metallic continuous guide 6 set therein, as shown in Figs. 2 and (5, into which the projections 4 is a skeleton perspective view showing the c from the hinge-arms extend and guide the said hinge-arms, preventing lateral movement and wear upon the arm-rests. By this construction it is evident that there are no projections or other obstructions upon the arm-rest upon which to catch the clothes or strike the arms. It is preferable that this guide 6 be made curved, as shown in Fig. 2, using c as the center, and I prefer to provide each end of the guide with stops 2-, against which or between which a suitable springcatch J, carried by the hinge-arms, may work, to control the adjustment of the seat-back. The catch J is clearly shown in Figs. 2, 4, and 6, and extends down so as to be guided upon the fulcrum c of the hinge-arm, its lower extremity being provided with a lug J. This lug is received in a curved slot L of the leverframe K, which is held up toward the fulcrum c by a lever M, having a cross-head at the top m, resting under said lever-frame K, and a spring N, arranged in the frame A and adapted to press upon the under side of the cross-head, to move the lever H upward. The action of these parts is to thrust the catch J upward, causing its end j to catch upon the stops 6. The curved groove Lallows the hinge arms to be shifted in reversing the seat-back without displacing the connection between the catch J and the lever-frame K. The lever frame K is held up against the upper flange of the frame D, through which it has two projections 716, one upon either side of the fulcrum c. The function of these projections is to provide means for the occupant to depress the lever-frame K against the action of the spring N and withdraw the catch J from the projection e, and it is evident that one of such projections at each end of the seat will be in easy reach of the occupant for each reversed position of the seat-back. There is a similar spring-catch device upon each end of the seat, and such spring-catches may be operated from either end of the seat by simply connecting the levers M by means of a bar 0, extending thelength of the seat.

Referring to Fi 6,1 have shown a form of lock which may be employed to prevent the reversal of the seat, if desired. In this construction R represents the .lockin g device car'- ried by the hinge-arms G. S is the lockingbolt, which is adapted to snap into a recess 3 in the catch J, and is operated through the mediation of a spring Q. In the socket of the lock are two parallel ribs 1, upon which the bolt S is guided. The bolt S is provided with a flange having notches T, for receiving the guide-ribs t, and said bolt maybe drawn back by the insertion of the key until it leaves the guide-ribs, and then by turning its flanges will rest against the said ribs and the bolt will be thrown out of action. Any other form of locking device may be employed, if desired.

I do not limit myself to the mere details of construction, as it is evident that they may be modified and varied to suit the ideas of the designer; but the principles of construction would remain the same. While I have shown a complete seat with both ends exactly alike, it is evident that one end may be constructed against the car-wall, as is customary, and in that case the guide 6 may be bolted to the said walls in place of the arm-rests.

Car-seats of this nature can readily be made in pairs, each having independentlyoperated backs and seat-cushions, so as to be separately adj usted and with capacity to form what are known as tete-a-tte chairs, which are simply two such seats as here shown arranged side by side.

In this application I do not claim, broadly, the hinge-arm and locking-bolt carried wholly thereby to engage a groove in the seat-arm, nor the hinge-arm having a lug thereon to engage a continuous groove in the seat-arm to prevent lateral play of the back, as these features are the subject-matter of my application, Serial No. 286,395, wherein they are broadly claimed.

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

1. In a car or other seat, the combination of the rigid main frame, a reversible seatback independent of the seat-cushion, two

hinge-arms pivoted to the main frame and permanently connected at their upper ends to the seat-back, stationary or fixed arms secured to the main frame and provided with a continuous guide having stops to limit the throw of the hinge-arms, catches to secure said hinge-arms to said stops, a lock to prevent said catches being operated, and a sliding connection between the hinge-arms and guides.

2. In a car or other seat, the combination of the rigid main frame having an arm formed with a continuous curved guide for the hingearm connected to the main frame below the guide, a pivoted hinge-arm for supporting the seat-back at its middle by a permanent 1 pivotal connection and, guided in said armguide, and a hand-operated locking device extending to the pivot of the hinge-arm with the main frame to secure said hinge-arm rigidly at each end of the guide.
