RATCH ET-BRAKE FoR CARS.
SPECIFICATION forming' part of Letters Patent No. 485,548, dated November 1, 1.892.
Application filed July 6, 1892. Serial No. 439,157. (No model.)
.To all whom t may concern:
Be it known thatI, PETER M. KLING, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Ratchet-Brakes, 0f which the following is a full, clear, and exact description,ref erence being had to the accompanying drawings, forming part of this specification.
My invention relates to a ratchet-brake for street-cars; and it consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a View, part inelevation and part in vertical section, taken on line I I, Fig. II. Fig. II is a transverse section taken on line Il II, Fig. I, looking in the direction of the arrows. Fig. III is a similar View taken on line III III, Fig. I.
Referring to the drawings, 2 represents the usual vertical brake-rod of a street-car.
3 represents the handle of the brake, which is socketed to fit over the upper end of the brake-rod. The rod is provided with a groove 4 to receive the inner end of a pin 5, which passes through the socket end of the handle. The pin permits the handle to turn on the rod, but prevents its vertical movement. The
upper end of the rod is provided with a number of elongated teeth 6. v
7 represents a block fitting in an enlargement of the handle, the heel 8 of the block having a bearing at 12 in the socket of the handle. The forward end bears against the -ratchet-teeth, as shown clearly in Fig. II.
` the brake-rod having elongated ratchet-teeth,
a handle having a socket end with an enlarged recess, a block fitting in the recess of the handle and having abearing at l2, a hollow plug fitting in the handle, and a spring in said plug for forcing the block into engagement with the ratchet-teeth, substantially as set forth.
2. In a ratchet-brake, the combination of the brake-rod having elongated ratchet-teeth, a socketed handle having a recess, a block in said recess having a bearing l2, a hollow plug fitting in the handle, a spring fitting in said plug, land a cap tting over the spring, substantially as and for the purpose set forth.
