CAFt-SEAT.

SPECIFICATION forming part of Letters Patent No. 789,248, dated May 9, 1905. Application filed January 20, 1905. Serial No. 241,926.

T 0 all whom, it may concern/.-

Be it known thatI, HIRAM E. AYCKERLY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Oar-Seats, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to car-seats, and more particularly to that class of car-seats which comprise a back that is reversible with respect to the frame, whereby the facing direction of the seat may be reversed at Will.

The object of my invention is to provide a superior construction of supporting and reversing mechanism for the back and also refers to the parts effecting the reversal in the position of the bottom and of the foot-rest.

I will first describe a car-seat embodying my invention and then point out the novel features in the claims.

Figure 1 is a side elevation looking from the interior toward the end frame-plate of a step-over car-seat embodying my invention and showing so much of the mechanism thereof as affects and regulates reversal of the back. Fig. 2 is a central cross-section elevation of the parts shown in Fig. 1. Fig.

' 3 is a side elevation similar to Fig. 1, but of a modified form of my invention, showing its application to a so-called turn-over carseat namely, onein which the back is inverted during the movement of reversal. Figs. 4 and 5 are detailed views of parts shown in Fig. 1.

Similar letters of reference are employed to designate corresponding parts in the several figures.

A represents what may be termed an end plate and is a part of the stationary frame.

B is the back, which may be upholstered in any well-known manner.

0 represents a plate having fixed relation with the back B by being secured thereto. The partO is preferably of an inverted-T form and has pivoted to it the two long supporting-links D E, which, together with the plates O and a short lower link F, form a quadrilateral of links. This quadrilateral in Fig. 1 takes the form of a parallelogram; but in Fig.

3 the supporting-links are crossed. The upper member O is arranged at about right angles, by which 1 mean at any angle substantially ninety degrees to the plane of the back. In the modification of Fig. 1 afixed pivot for the linkage is provided at 0 intermediate the ends of link E. When the back is reversed, the extension of arm E below its fixed pivot oscillates, and thereby effects a forward and backward movement of short link F, which I therefore term a floating link, it having no stationary point or pivot.

To prevent loose play of the parts and afford a positive controlling means for regulating the tilt of the back in its various positions, I have provided a guiding means which connects with the floating link F at some point f removed from the pivot connecting the links E and F. Instead of a cam or a guide I- prefer to employ a short swinging arm G, having a fixed pivot g in the frame and connected at f with the link F, whereby the arm G positively determines the path of movement of the link F, and thereby affords a positive control of the position or slant of the link or member of the quadrilateral which is opposite the link F-namely, the plate O which bears a fixed relation to the back. By the above-described mechanism the position of the back is predetermined for all stages of its movement of reversal.

In the construction Fig. 1 the supportinglinks D E are substantially parallel, and the back remains substantially vertical While being stepped over, but assumes a slight backward inclination from other extreme position. In Fig. 3, however, the supporting-links K L being crossed, the back will be inverted or revolved as it is reversed, and therefore somewhat different proportions of the links are necessary, as illustrated.

It is usual in this class of car-seats to provide a forwardly and backwardly moving bottom, which is shown in the present illustration as a cushion H, supported upon a rockerplate H, to which a forward and backward movement is communicated through a slot engaging a pin on the floating link F. The rockers H may for convenience rest directly upon lugs J, which serve also as supports for ICO the cross-bars J. Of course the mechanism above described or its equivalent should be duplicated at each end of the car-seat.

It is often desirable to have a reversible foot-rest, an example of which I have shown in Fig. 3 as consisting in arms M M, revolving about ashaft and carryingthe bars m, upon which the foot may rest. Another arm, N, on the same shaft as M is provided with a cam n, which may be actuated from the floating link F in a manner similar to the shifting of the rocker-plate H, as already described.

What I claim as my invention is 1. In a car-seatthe combination of a frame, a bottom, a back reversible relatively to the frame and bottom to change the facing direction of the seat, and at each end of the carseat the following: a four-sided linkage for supporting the back and controlling its reversing movements, the upper member of the linkage being in fixed relation with the back, the lower member being a short floatinglink, one of the two long connecting-links having a stationary pivot, and a pivoted arm for controlling the movements of the floating link, and thereby regulating the tilt of the back.

2. In a car-seat the combination of a frame, a bottom, a back reversible relatively to the frame and bottom to change the facing direction of the seat, and at each end of the carseat the following: two supporting-links pivoted at separated points to the back, and at their other ends to a short floatinglink, a pivot upon one of said supporting-arms fixed relatively to the frame, and means connected with the floating link for positively controlling the movements of the links and the back while the latter is being reversed.

3. In a car-seatthe combination of a frame, a bottom, a back reversible relatively to the frame and bottom to change the facing direc tion of the seat, and at each end of the carseat the following: two supporting-links pivoted at separated points to the back, one of said supporting-links having a fixed pivot intermediate its ends, a short floating link connecting said supporting-links below said fixed pivot, and a positive guiding means acting upon said floating link at a point removed from the latters connection with the supporting-link which has a fixed pivot, whereby the tilt of the back is automatically controlled throughout its reversing movements.

4. In a car-seat the combination of a frame, a bottom, a back reversible relatively to the frame and bottom to change the facing direction of the seat, and at each end of the carseat the following: two supporting-links pivoted at separated points to the back, the first thereof having a fixed pivot and a downward extension therefrom, a short backward and forward moving link pivoted to said extension and to the second supporting-link, and a swinging arm pivoted to said short link for positively controlling its path of movement, substantially as and for the purposes set forth.
