CAR-SEAT.

Patented Nov. 18, 1913.

Application filed June 18, 1909, Serial No. 502,904; Renewed April 7, 1913. Serial No. 759,572.

To all whom, t may concern: Y

Be it known that I, FREDERICK BENNETT, ofRavenswood, Long Island, New York, and v,whose post-office address is 517 West Twenty-ninth street, borough'of Manhattan, city'and State of New York, have 1nvented certain new and useful Improvements in Car-Seats, of which the following is a full, clear, and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates particularly to proved devices for mounting and shifting the foot rest of a car vseat simultaneously with the shifting of the back and cushion thereof, and it has for its object to provide mechanism for this purpose which will be positive and certain in its operation and entirely free from rattling and uncertain action and by which the foot rest will be securely locked in both of its eXtreme positions, making it possible to shift the foot rest or seat by pressure against the former. I attain this and other objects by certain novel features of construction and combinations o-f parts which will be fully set forth hereinafter and particularly pointed out in the claims.

Reference is now had to the accompanying drawings which illustrate as an eXample the preferred manner in which the principle of my invention may be embodied.

In these drawings-Figure 1 is an inner side elevation of the mechanism at one end of the seat, the view omitting the cushion and back. Fig. 2 is an enlarged section on the line 2-2 of Fig. 1. Fig. 3 is a sectional elevation on thelineB-S o-f Fig. 2, and Figs. 4 and 5 are views illustrating the cam surfaces of the inner section of the actuator.

While my invention relates primarily to the devices for mounting and shifting the foot rest and is applicable to any car seat, it is especially designed for use in connection with the cushion and backV actuating devices forming the subject of my cof-pending application Serial #454,599, filed September 24, 1908, and in Fig. 1 it is shown in connection with such devices. In said view 10 indicates one of the two frames for pedestals at the sides of the cushion. To

.a guide 20 in the lower end of the arm 12. By these devices the arms of the back and hence the back itself is mounted and held securely in either adjustment and allowed to swing freely from one position to another, all of which is fully set forth in the co-pending application referred to.

The shaft 15, to which the swinging arm 14 is attached, has an enlargement 21 adjacent to the arm. This enlargement may be formed in any desired manner; it is here shown as a sleeve keyed to the shaft. Loose on shaft 15, and abutting against the enlargement 21, is a tubular shaft 22, which carries rigidly at its inner end (the righthand in Fig. 2) the outwardly projecting arm 23 of the foot rest 24. Outward of said tubular shaft 22 the end of the shaft 15 carries a collar 25 keyed to the shaft.

f The actuator 26 is here shown in the form of a sleeve which loosely embraces the enlargement 21 of the shaft 15 and the sleeve 22, and which is adapted to slide on these parts, but is prevented from rotating by means ofledges 27 at the sides of the actuato-r which bear on track bars 28 fastened to a projection extending inwardly fro-m the pedestal 10 and braced at their inner ends by a yoke 29 which passes under the tubular shaft 22.

As shown best in Fig. 4, the actuator 26V is constructed of two sections keyed to each other. This is a matter of convenience only and if this construction is followed the inner section 26a is provided with a spiral groove 30, in which is received a pin 31 projecting from the enlargement 21 of the shaft 15. The actuator 26*l is also provided with. a spiral L roove 32, the ends of which run into straigglit or longitudinally disposed portions 32a; and in this groove 32 is loosely received a pin 33 fastened to the tubular shaft 22. By this arrangement upon the rocking of the shaft 15 and its enlargement 21, due to the swinging of the arm 14, the pin 31 will act upon the side walls of the groove 30, and since the actuator 26 is incapable of rotation, it will be forced to move longitudinally on the shafts 15 and 22.V This longitudinal motion of the actuator 26 causes the walls of the groove 32 to act on the pin 33 and impart a partial rotation to the shaft 22, owing to the fact that this shaft is incapable of axial motion by reason of the collar 25. This partial rotation of the shaft 22 brings about a swinging motion of the foot rest, and in this manner the foot rest is shifted.

The organized operation of the mechanism may be traced, as follows: Upon shifting the back of the seat from one position to another it is necessary to shift the foot rest but in a reverse direction. Consequently, as the back is thrown over, its motion brings about a swinging of the arm 14C and a rocking of thek shaft 15 but in a direction reverse` to that in which it is necessary to swing the foot rest. This rocking of the shaft 15 brings about the before-described sliding motion of the actuator, and owing to the reverse disposition of the cam grooves 30 and 32 the shaft 22, arm 23 and its attached foot rest are caused to move reversely. Therefore, as the back is thrown in one direction the foot rest is caused to move oppositely toA shifted position. As the actuator reaches the ends of its motion the straight portions 32a of the groove 32 engage the pin 33 and form a positive locl for the foot rest, so that a person pressing against the same will be unable to change its position.

It will be seen therefore that by means of my invention a positive connection is established between the back and the foot rest and that the foot rest is shifted with a positive motion reversely to the motion of the back. It will also be seen that the actuator andl the parts concerned therewith involve a certain amount of friction which prevents idle motion of the parts and hence eliminates any rattling or loss of motion. It also eliminates any liability of the back to play idly from one position to another.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
