IMPROVEMENT IN AUTOMATIC WAGON-BRAKES.
Specification forming part of Letters Patent No. 203,093, dated April 30, 1878 application filed November 30, 1877.
To all whom it may concern:
Be it known that I, LOREN L. TRAVIS, of'
Lemon, in the county of Wyoming and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Wagon-Brakes; and I do hereby declare that the following is afull, clear, and exact description of my invention, that will enable others skilled n the neck-yoke against the lever on the under side of the tongue, to whose rear end is attached a lever passing through a slot in the tongue. Pivoted'therein and to the upper end of said lever there is a plurality of levers, connected with an evener, the ends of which are each connected with the pivoted levers, to which the brake-blocks are attached.
The object of my invention is to furnish a brake which shall press evenly on both wheels, although the brake-block of one mayhave become much thinner by wearing than that of the other.
In the drawings, Figure l is a plan view of the lower part of a wagon, showing my invention. Fig. 2 is a detailed sectional view of my invention, showing the lever beneath the tongue, and the manner in which it is connectedwith a lever passing through a slot in the tongue, and thus connecting with the plurality of levers extending over the fore axle and reach. Fig. 3 is a side view of the brake-blocks or friction-shoes.
A is the tongue. B is the lever beneath the tongue. 0 is the lever which passes through a slot in the tongue. D is the series of levers which are connected with the evener E. F is a cross-bar, connecting the front end of the rear hounds, to. the ends of which are pivoted the levers G G, and to the extremities of these two levers are connected the friction-shoes H H. II are elastic springs, fastened at one end to the rear bolster K, and at the other end to the levers H H.
The whiffletree a operates on the pivot 11, which is rigidly attached to the lever B. The evener E is connected with the levers G G by the short levers c c.
It is now evident that, when either of the friction-shoes H or H becomes more worn than the other, the pressure upon the wheels is made uniform and equal, in consequence of the elastic springs I 1 operating with the evener E upon the levers G G.
Having now fully described my invention, Iclaim and desire to secure by Letters Pat'- ent- The elastic springs I I, fastened at one end to the rear bolster K, and at the other end, each respectively, to the levers G G, in combination with the short connecting-levers c c, the evener E, the series of levers I), and the levers G and B, substantially as shown and described, and for the purposes herein setforth.
In testimony that I claim the foregoing I have hereunto set my hand this 6th day of November, 1877.
LOREN L. TRAVIS.
