SPECIFICATION forming part of Letters Patent No. 542,411, dated July 9, 1895.

Application ined october 13,1394.

.To til whom it may concern:

Be it known that I, JOHN S. JOHNSTON, a citizen of the United States, residing at Chi cago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Car-Seats and Similar Constructions, fully described and represented in the following specitication and the accompanying drawings, forming a part of the same.

The object of the present invention is to provide an improved car-seat of that class in which the back may be shifted for facing in opposite directions, the invention relating especially to an improved construction of arms, by which the back is reversed or changed from one facing direction to another, and to an improved foot-rest of general application in this class of constructions, which is automatically shifted with the back and thus brought into position for use on the rear side of the seat to which it is applied, while on the front side it is carried out of the way of the feet of the occupant of the seat. l

The invention also includes improved constructions for shifting the seat proper when the back is reversed and devices for locking the back-reversing arms.

For a full understanding of the invention a detailed description'of a construction einbodying all the features of the same in their preferred form will now be given in connection with the accompanyingr drawings, forming a part of this specification, and the features forming the invention then specifically pointed out in the claims.

In the drawings, Figure 1 is a vertical section of thc seat, taken inside the frame on the line 1 of Fig. 2. Fig.. 2 is a vertical section on the line 2 of Fig. l. Fig. 3 is a view similar to Fig. l, showing the seat in its central position during reversal. Fig. 4 is a similar section showing the seat reversed from the position shown in Fig. l. Fig. 5 is an enlarged detail of the upper ends of the reversing-arms and locking devices. l Fig. 6 is an edge view of thesame. Figs. 7 and 8 are sections on respectively the lines 7 and 8 of Fig. 5. Figs. 9 and 10 are respectively side and edge views of the arms. Fig. 1l is a detail section onthe line l1 of Fig. 1.

Referring to said d rawings, A represents the Serial No. 525,799. (No model.)

side frames of the seat, provided with sills B, on which the seat O rests, the sills and seat beinginclined, as usual in such constructions, so as to change the incline of the seat as the latter is shifted.

Each of the sills B preferably consists of an iron plate extending the length of the seat and secured at opposite ends by being bolted to lips 10,"formed on the side frames A, the sills being preferably provided with flanges 11 on their inner edges, for a purpose to be described hereinafter.

Pivoted to the side frames A by pivots 12, and preferably at each end of the seat, are a pair of reversing-arms D D', the upper ends of which are pivoted to the seat-back, as follows: At each end the back E has secured thereto a plate 13, on which is the pivot l for the arm D, and over thisV plate extends the cap 14, having a supporting-liange and ears 16, by which it is secured to the plate 13 and back. This cap 14 is provided with an inwardly-extending pivot 2 for the arm D', the upper ends of the two arms D D' thus being mounted within the space between the capA 14 and back covered by the former, while by the pivoting of the arms, one on the back plate and the other onthe cap, each of the arms is permitted to overlie the pivot of the other arm, so that the arms maylie side by side throughout their entire length without reducing the width of the arms or cutting away the pivots.

As will be seen from the drawings, the arms D D in the preferred construction shown are duplicates, being reversed in assembling, Aso as to be pivoted to the side frames and back on opposite sides of the vertical center and cross each other, as shown in the general views, and their construction is as follows, referring particularly to the detail views, Figs. 9 and 10:

The arms have straight portions extending from the seat to the back, these straight portions intersecting and lying one upon the other in the normal positions of the arms, so that, being of equal Width, there appears from the side to be but a single arm in either normal position of the back, as shown in Figs. l and 4, the bent pivoting portions at the lower ends lying opposite the seat O. These intersecting straight portions of the arms are of such width and the arms pivoted at such points IOO that in reversing the seat the arms are not separated at their inner edges and all danger of catching the lingers between them is thus avoided, as shown clearly in Fig. 3.

Each of the armsis provided with two stops for the other arm, so that each arm provides a support for the other arm in the two normal positions, and the arms and back are thus supported Without any support on the seatframe other than the pivots 12. In order that the two arms may lie one upon the other with their edges in the same plane in the normal' position of theback these stops are in line with the opposite edges of the arms. These stops may be formed in any suitable manner, either by securing stop pieces or pins to the arms or by forming the stops integraltherewith, as by bending or reducing the thickness of the arms; but the construction shown is preferred, in which the arms are reduced in thickness throughout the greater portion of their length, so as to ferm shoulders at the upper and lower ends, these shoulders extending parallel with and in line with theopposite edges of each arm, so that they form extended bearing-surfaces for the edges of the other arm.

The arm D has shoulders ot b, and the arm D is provided with corresponding shoulders a b', These shoulders a, a' not only form stops, but also ll the spaces at the front of the cap 14 above the other arms in the normal position of the back, as shown in Figs. 1, 2, and 4, thus improvingr the appearance of the construction. With these arms any suitable locking device may be used or no locking devices provided. In the preferred construction shown the arms D D are also provided, respectively, -with locking-notches c c', and at its outer edge each arm is preferably constructed to form notches d d on the respective arms D D for holding the backin central position during reversal.

The locking devices coacting with the notches c c and d d' `preferably consist of a bar 17 carried by a hollow stem 18 mounted to slide in the flange 15 and normally springpressed inward by aspring 3. The bar 17 thus lies inside the cap 14 opposite the ends of kthe arms D D', and it is held in position and guided by a pin 4 on the inner side, run.- ning in a slot 5 in the plate 13. This bar 17 is provided at opposite ends with projections 6,one of which engages in one of the lockingnotches c c of the arms D D' in either normal position of the back and locks the latter against movement, this locking being automatic in shifting the back, the spring 1S forcing the bar 17 against the arms D D, so that the catch 6 passes into the notch'in one of the arms when the latter is brought opposite the catch by thefull reversal ofsthe back.

adapted to enter the hollow stem and is slotted 'to form a bayonet-joint, so that, when turned slightly after insertion, the pin is held and the stem may be drawn outward with the bar 17, releasing the catch and unlocking the arms. When the arms are in their central position, the catches 6 at opposite ends of the bars 17 engage the notches d el', as shown in Fig. 3, and hold the back and seat in central position; but the catches do not lock the back in this position, but permit it to be fully reversed by pressure upon the back. The notches CZ cl may be omitted in case it is not desired to provide means for holding the seat in central position.

The straight portions of the arms, which lie upon each other in the normal positions ofthe back, may be plain flat bars of metal; but in order to avoid friction and wear ofthe arms, as well as to lighten the construction, it is preferable to use bars of the form shown reduced in thickness, so as to engage only at their edges by shoulders 8, suliicient strength of construction thus being secured, while at the same time reducing the friction and wear to a minimum. v

The construction thus far described forlns in itself a part of the invention independently of the foot-rest, now to be described,.or the ,shifting of the seat; but the invention includes also a shiftable foot-rest and an improved device for shifting the seat proper, which will now be explained.

If the seat were not to be shifted and no foot-rest were to be used it will be understood that the arms D D' might terminate at the pivots 12.; but in the construction shown these arms are provided with extensions ff below the pivots 12, and these extensions engage the upper ends of the levers 19, one of these at each end of the frame preferably being employed, these levers being pivoted to the frame at 20 and carrying at their upper ends pins 9, which engage slots in the end frames of the seat C, so as to shift the latter with the levers 19. These levers 19` also actuate the shiftable foot-rest, which will now be described.

The foot-rest may be of any suitable construction, but preferably is formed of a metal frame consisting of side bars 21,0n the opposite ends of which are mounted wooden bars 22, which form the foot-rest bars, and this lframe is shifted transversely to the seat in accordance with the facing direction of the seat and preferably has a sliding connection with some convenient portion of the seatframe and is arranged to be actuated by the back-levers, so as to shift the foot-restas the back is reversed. The sliding `connection between the foot-rest and frame is preferably some form of pin-and-slot connection, the slot beingso formed as to secure the desired movement of the foot-rest as it is moved backward and forward.

It is desirable that the foot-rest should not only be projected at the rear of the seat and withdrawn from the front of the seat when the back is reversed, but that'the foot-rest should also be carried out of the way of the feet of the occupant of the-seat and lowered into convenient position at Athe rear of the seat for use. In the construction shown this-result is secured by tilting the foot-rest at the same time that it is shifted transversely to the seat, so as to raise the side of the foot-rest at the front of the seat and lower the side of the foot-rest at the rear of the seat. This end. is attained by providing the side frame A of the seat with slots 23, which may be cut through the side frames, but preferably are formed, as shown, upon theinner sides of the frame, so as not to show upon the outside of the seat, these slots receiving lugs 24,'secured to each of the side bars 2l of the foot-rest, these lugs beingof such form as to hold the foot-rest steady in the position to which it is shifted, while passing readily the central part of the slots 23. The slots 23 are of sufficient length to permit the rest to be shifted back and forth, so as to project the requisite distance beyond either side of the seat, these slots being inclined downward in opposite directions from the center of their length, each of the inclined portions of the slot being of suicient length to receive the lug 24:, this double-inclined slot securing the'tilting of the foot-rest in shifting, as previously described. The portions of the double-inclined slot are shown in the drawings as straight, and this form is preferred to a curved slot, but it will be understood that the form of the slot is immaterial, so long as it is so constructed as to tilt the foot-rest as desired.

Stops 25 on the side frames Aare preferably provided,which support the sides of the footrest, .so as to prevent the strain of the footpressure being brought upon the lugs 24. The side of-the foot-rest not in use is brought up against the sill l0, as shown in Figs. l and 4, and to secure a level bearingsurface for the foot-rest against the sills, independently of the wear of the wooden rest-barsfthe flanges ll, previously described, are used, which engage the metal bars 2l.

The foot-rest may be shifted automatically on the rev'ersal of the back by any suitable means, and these means will vary with the construction of the seat to which itis applied. With baclrreversing arms of the class shown the levers 19 are preferably employed,these levers being provided with slots 26, which en# gage studs 27 projecting inwardly from the bars 2l of the foot-rest, so that as these levers 19 are oscillated bythe projections ff of the arms D D in reversing the back the footrest is shifted, as shown.

The operation lof the construction will be clear from Figs. l, 3, and 4, showing all parts of the seat in the two normal positions and in the central position in reversing.

It will be seen from Fig. 3 that in reversing as the studs 24 pass the central portion of the slots 23 both sides of the foot-rest are raised some distance from lthe Iioor, so as to give t'ree access beneath the seat Afor sweeping, dre., and the seat is held in this position, as previously described, by the catches 6 on the bar 17V engaging the notches d d' of the arms D D with sufficient firmness for this purpose, although not preventing the seat being entirely thrown over by the exertion of slight force by the operator. A car may be cleaned very conveniently, therefore, by simply throwing the backsinto the central position, (shown in Fig. 3,) thus raising the foot-rests.

It will be understood that the foot-rest described herein may be used with other backshifting constructions and in itself forms a part of the invention5as. claimed. The two features of the improved back-reversing con'- struction and the shiftable foot-rest, however, are preferably used together, forming a complete car-seat of improved construction.

It will be understood also that modilications may be made in the construction shown as embodying the invention without departing therefrom, and the invention is not limitedto the exact construction shown. Vthile the invention has been illustrated and described as applied to car-seats and is of especial value as applied thereto, it is applicable also to other seats and similar constructions employing a reversible member or shiftable foot-rest.
