CAR-S EAT.

SPECIFICATION formingpart of Letters Patent N 0. $7,034, dated November 29, 1892.

*of theUnited States, residing at akefield, in

the county of Middlesex and State of Massachusetts, have invented certain new and usewill enable othersskille fied arrangement of parts.

ful Improvements in Car-Seats; andI do hereby declare the following to be a full, clear, and

invention, 'such as inthe art to which it appertains to make and use the same. My invention is an improvement in carseats; and it consists in the novel features of construction and combination of parts hereinafter fully described.

In the accompanyingdrawings I haveshown severalforms in which I have contemplated exact-description of H3 embodying my invention, and said invention is fully disclosed in the and claims:

Referring to the said drawings, Figure 1 is a view of one of the sides of a car-seat embodying my invention from the inner side, showing the position'of the seat and back cushions in dotted lines. Fig. 2 is a longitudinal sectional view of the seat portion. Fig. 3 is a detail View of the rocker of the seat, with its operating-arm connected thereto. Fig. 4 is a similar view of a slightly-modi- Fig. 5 is a similar view showing still another slight modification of the arrangement of said parts.

In the drawings, A represents the side frame of a car-seat constructed in the usual or ordinary manner, having the supporting or foot portion a and the seat-arm a, provided with brackets a to receive the pivoted strikerarm, and said brackets maybe provided with the usual latch, if desired. The side frame A is also provided with a support for the seat portion, which consists of a track or way A, having its ends curved or bent upwardly, as at a following description B is the seat proper, which consists of the' end pieces or rockers b and suitable connectlug-framework, the said rockers having their ends curved or beveled. The rockers b are adapted to engage the ways or supports A of the side frames of the car-seat, and when the forward or rear ends of the rockers are made to engage the upwardly curved or bent portions of the ways or tracks of the sides the Application filed February 10, 1892. Serial No, 420,991- (No model.)

seat is held in an inclined, position, as will be seen in Fig. 1..

The back 0 is formed in the usual manner and provided with the end irons 'c, which are connected to the side frames by the strikerarms D, pivotally attached to the sidelframes at d and pivoted to the end irons c at d, and by the seat-operating arms E, which are pivoted to the side frames ate and to the end irons cat e. I prefer that the striker-arms should be pivoted to the end irons cat points slightly above the center of the back and that the seat-operating arms should engage the back arrangement of parts. The. seat-operating arm or lever E is nearly parallel to the striker arm D when the latter is in engagement with one of the brackets a and is of such length that when the seat is shifted it will pass beneath the point (1, where. the

striker-arm is pivoted to the side frame, as clearly shown in Fig. 1 in dotted lines.

The seat-operating arm is connected with the seat in such a manner that when the back is raised and swung over to the other side of the side frames the said arm E-will thrustthe seat in the opposite directioincausing the rockers b to slide along the supports or guideways A and engage the upwardly-extending portions of the same, thereby elevating the edge of the seat which is opposite the back, as will be readily'understood. I may eifect the connection between the arm Eand the seat in various ways. shown the arm E provided with an extension e which is provided with 2. lug

or pine, en-" s In Figs. 1 and 3 I have gaging an elongated slot or recess b in the I rocker b, thus causing the seat to move in the required manner when the back is moved from one side to the other. In Fig. 5 I have shown this arrangement reversed and the rocker Z) provided with a pin or lug b to on gage an elongated slot or recess e in the arm E. In Fig. ing the extension e rocker b, which will efiect the same results in imparting the desired movements .to the seat, the said link being pivoted to the rocker at e", as shown. In this form the arin E will be pivoted to the seat-frame by the pin e.

too

The operation of myimproved ear-seat will be apparent from thedrawings. When it is desired to reverse the seat,the back is raised and moved to the other side of the side frames, the striker-arms and seat-operating arms moving in the arcsindieated by dotted lines in Fig. 1. The seat will be moved'by the arms E and caused to travel along the guideways A until the rockers b engage up Wardly'extending portions of the said guide- Ways, when the seat will be raised on,the edge: opposite the back and given the desired inclination.

It will be noticed that in the constructions herein shown and described the seat-operating parts are so formed that when the seatis in normal condition with the back in either position the seat-will be locked, so that pressure exerted upon itin a horizontaldirection will have no tendency to change the positions of the said operatingpartathe seat-operating arms E and the part or parts connecting, them with the seat prop rbeing at's'uch times in almost a'horizontal line. Y1 '1' do no tdesire to limited to the exact details of construction herein shown and described, as variations uay be made in the same without departing from the spirit of my invention. "I
