SPECIFICATION forming part of Letters Patent No. 542,39S dated July 9, 1895. Application filed J ly 7, 1894:. serial No. 5l6|808- (No model.)

To all whom it may c0n0ern.-' I

Be it known that we, WILLIAM P. S'IYMUS, Jr., and AUGUST; F. KREUTZBERG,citizens of the United States, residing in the city, county, and State of New-York, have invented'certain new and useful Improvements in Car-Seats and Similar Constructions, fully described and represented in the following specification 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 is supported by arms lyingin parallel planes and so arranged as to'reverse the back in shifting it for facing in opposite directions, the especial object of the inven tion beingto provide an improved construction by which danger of catching the fingers between the arms in reversing shall be avoided, and,further, to provide such a construction in which the two arms shall lie side by side in either normal position of the'seat, so as to have the appearance of but asingle arm. The first result is attained by the use of pairs of reversingarms so constructed that they are not separated at their inner edges between the seat and back in reversing, thus affording no space for the fingers to enter,

-and these arms preferably are of the same width and lie one upon the other above the seat in either normal position of the back, so as to have practically the appearance of one These arms are preferably so combined with the seat as to shift the latter in reversing the back, as usual in such constructions, and they are also preferably used in combination with a foot-rest shifted by the arms in reversing the seat, so as to bring the restin toposition for use at either side of the seat, according to the direction in .which the back is faced.

The invention includes also improved looking devices by which the back is automatically secured in either normal position when similar section showing the back reversed from the position shown in Fig. 1. Figs. 5 and 6 are, respectively, side and edge views on an enlarged scale, showing the locking devices. Figs. 7 and 8 are, respectively, side and edge views of oneof the arms.

Referring to said'drawings, A represents the frame of an ordinary car-seat provided with seat-sills B, on which the seat 0 rests,

the sills and'seats being inclined, as usual in such constructions, so as to change the incline of the seat as it is shifted. Pivoted to the side frames A'by pivots 10, at each end of the seat, are a pair of arms D D, the upper ends of which are pivoted to the seat-back E, the back being shown as provided with a plate 11, having projecting studs 1, forming pivots for the arms. It will be understood, however, that the back may be pivotally mounted on the arms in any other suitable manner. The arms are pivoted to the seat frame and back on opposite sides of the vertical center, as shown clearly in Fig. 3, lines joining the pivots of the two arms thus crossing each other.

As will be seen from the drawings, the arms D. D in the preferred construction shown are duplicates, being reversed. in assembling, and their. construction is as follows, referring particularly to Fig. 7 and 8: 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 position of the arms, so that, be-

- ing of equal'width, there appears from the side to be but a single arm in either normal position of the back, the bent pivoting portions at the lower ends lying opposite the seat. These intersecting straight portions of the arms are of such width, and the arms pivoted at such points, that in reversing the seat the arms are not separated at their inner edges, and all danger of catching the fingers between them is avoided. Each of the arms is provided with two stops for the other arm, so that each arm provides a support at one end for the other arm in the two normal positions. In order that the two arms may lie one upon the other in the normal positionsof the back, 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 integral therewith by bending or reducing the thickness of the arm; but the construction shown is preferred, in which, as shown clearly in Figs. 7 and 8, the arm is reduced in thickness throughout the greater portion of its length, so as to form shoulders at its upper and lower ends, these shoulders extending parallel and in line with theopposite edges of the arm, so that they form extended bearing-surfaces for the inner edges of the other arm. The arm D has shoulders a b, and upon one edge, just below the shoulder (1, is provided with a notch c, for a purpose presently explained, and on. opposite sides, at the end, with locking-notchesd e. The arm D is provided with corresponding shoulders 0/ b and notches c d e. i

.If the seat is not to be shifted or no footrest is to be used, it will be understood that the arms D D may terminate at the pivots 10, but in the construction shown, which includes the features of a shifting-seat andfootrest, these arms D D are provided with extensions ff below the pivots 10, and these extensions carry pins 2, which enter slots 3 in the ends of the seat, so as to shift the latter as the back is reversed, and these extensions ff also actuate the foot-rest, as presently 'to be described. 1

The function of the notches c o is to permit the arms D D to come into the same plane and lie exactly one upon the other throughout their width when the seat-back is in either of its normal positions, these notches receiving the portion of the pivot-pin 1 of the other arm that lies outside the shoulder a. It will be understood that these notches are not absolutely essential, as the same results maybe secured otherwise, but the construc-i tion shown is simple and efficient.

The locking devices eoacting with the notches d e and d e consist of a pair of catchlevers 13, spring-pressed by spring 14, so as to hold the hook-catches at the ends of the levers normally in the notches e d or d e on opposite sides of the two arms D D. These two levers move together.

sition, as shown in Fig. 4.

1, the upper ends of the arms D D and the locking-levers are covered by a cap 12, provided with a keyhole, through which the key is passed to the arbor 4. It will be understood that any other suitable locking device may housed, and that it a locking device not requiring the notches d e and d c be used the construction of the arms D D may be further simplified. The locking device shown, however, is simple and etiicient and in itself forms a feature of the present invention.

'lhe'footrest F is provided at its opposite ends with bowls 15, which pass through camslots 16, inclined downward from both sides to the center of the frame, the foot-rest thus being mounted in the slots. These bowls 15 carry projecting studs 7, which enter slots 8 in levers l7, pivoted to the frame and provided at their upper ends with heads lying between and engaged by the extensions ff, so that the levers 17 are rocked in opposite directions by these extensions as the arms D D are shifted to reverse the back. I

The operation of the construction will be understood from a brief description in connection with the drawings. Then the seat is to be reversed from the position shown in Fig. 1, the levers 13 must be rocked to the right in Fig. 1 by a key on arbor 4, sd as to remove the hooks from the notches 6 cl in the ends of arms D D, and as the back is swung over the arms D D slide on each other as the seat is moved, but even in the central position shown in Fig. 3 are not separated above the seat, so as to permit of the catching ot' the fingers. In the position shown in Fig. 1 the arm D is supported by resting against shoulder to on the arm D and the arm D by resting against the shoulder 12 on the arm D; but as the reversal of the back is completed from the position shown in Fig. 3 and brought into the position shown in Fig.4 the arm 1.) comes to rest against the shoulder a of the arm D and the arm D against the shoulder 11 of the arm D, and as the back reaches its fully re versed position the spring-pressed levers 13 spring into the notches de in the ends of the arms and lock the latter in this reversed po- The shifting of the seatO and of the foot-rest F in reversing the back will be clear from the drawings, the seat 0 being moved to one side or the other on the inclined sills B, so as to cause it to project at what is the front. of the seat in each position and at the same time change the angle of theseat, this result being accomplished by the pins 2, working in the slots 3 in the seat, and the rocking of the lever 17 carries bodying the invention without departingfrom the latter, and the invention is not'to be limited to this exact construction; I

and describedgas applied to car-seats, ,it,will

be understood that itis applicable alsoto other seats and similar constructions employing areversiblc member.
