UNITED STATES PATENT OFFICE.
R. B. MORE, OF CINCINNATI, OHIO.
EMPROVEMENT IN CAR-SEAT LOCKS.
Specification forming part of Letters Patent N0. 39,303, dated July 21, 1863.
ings, making a part of this specification, in
which- Figure l is a side view of my invention, partly in section; Fig. 2, a plan or top view of the same; Fig. 3, adetached view ofthe key.
Similar letters of reference indicate corresponding parts in the several figures.
The object of this invention is to obtain a simple means for locking the backs of the seats of cars so that the backs cannot be turned over from one side of the seat to the other by the passengers.
The invention consists in attaching to the outer arm ofthe seat a spring-latch arranged so as to be thrown back by a key, and having a nosing on a bracket attached to the side of the seat, all being arranged in such a manner that as the back is turned and adjusted in proper position at either side of the seat the back will be locked, the latch engaging itself with the nosing of the bracket.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents a portion of the side or end piece of a car-seat, and B represents one of the arms to which the back of the scat is attached, said arm being secured as usual to the side A by a pivotboit, a, on which itis allowed to swing or work freely. The other arm ofthe back is attached in the same way to the other side or end piece of the seat.
To the end piece, A, which is the outer one of the seat, or the one by the side of the passa ge-way in the car, there is attached a case, C, (shown in section in Fig. 1,) in which a slide-latch, D, is fitted. This latch has its outer end rounded, as shown at b, and it has a spring, c, of spiral or other form, acting against it, which spring has a tendency to keep the outer end ofthe latch D thrown out from the case C, as will be fully understood by referring to Fig. 1.
To the end piece, A, of the seat there is attached a bracket, E, having a nosing, F, secured to or cast with it. (Shown 'in section in Fig. 1, or having a portion broken away.) This nosing projects out from the bracket and forms a rest for the arm B. The inner surface of the nosing F has a recess, d, made in it to receive the end of the latch D when the arm B rests in the nosing. This will be linderstood by referring to Fig. 1. The upper end of the nosing F is beveled, as shown at e, to form what is technically termed a strike to admit of the latch D being forced into the case C when the arm B passes into the nosing, the spring c forcing the outer end of the latch D into the recess d when the former cones in line with the latter. It will be understood, of course, that there are two brackets and nosings on the end piece, A, the arm B being attached to the end piece midway between the two, so as to admit of the back of the seat being turned and locked at either side of thc seat.
In order to unlock thel back of the seat, a key, G, is introduced into the case C through a key-hole in case C, the bit g of the key acting upon the 'slide-latch D and throwing it back, so that it will be free from the recess d in the nosing. Thus itwill be seen that the seat-back is rendered self-locking, a key being only required to open it. The arrangement at the same time is exceedingly simple, containing no parts liable to get out of repair or become deranged by use.
I do not claim, broadly, the application of a lock to a car-seat back; but
I do claim as new and desire to secure by Letters Patent- The spring latch D, applied to the arm B of the car-seat back, in combination with the nosing F on the bracket E, the former being provided with a recess,ld, and strike or beveled surface e, and all arranged substantially as and for the purpose specified.
