THOMAS E. ELLIOTT, OF MEDORA, ILLINOIS.
AUTOMATIC WAGON-BRAKE.
QPECIPICATION forming part of Letters Patent No. 374,950, dated December 20, 1887.
Application filed June 9, 1887.
To all whom it may concern:
Be it known that I, THOMAS B. ELLIOTT, of Medora, in the county of Macoupin and State of Illinois, have invented a new and Improved Automatic \Vagon-Brake; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention relates to an improvement in automatic wagon-brakes, my object being to provide mechanism more simple in construction and more reliable in action than that heretofore employed for the same purpose.
In the drawings, Figure 1 is a side sectional view, taken in the line :0 m, Fig. 2, of an ordinary farm-wagon provided with my brake. Fig. 2 is a plan view of the same without the wagon-bed. Fig. 3 is a front elevation of spring mechanism attached to the hounds for supporting the tongue.
In the drawings, A represents the wagon-.
bed supported upon small anti-friction rollers a, which are journaled in the bolsters b, the latter being of the ordinary form.
C is a coupling-pole, also of the ordinary form, provided at its sides with guide-plates 0, between which and upon the upper face of the couplingpole slides longitudinally a flat bar, 0, to which is secured a cross-bar, (2, adapted to travel in guides h. Upon the ends of said cross-bar are secured the brake-blocks 9. To the inner side of the rear bolster, at f, is fulcrumed a short lever, z, the lower end of which is connected by a rod, J, with the sliding bar 0, the upper end being connected with the bottom of the wagon-bed by a rod, k.
' To the forward part of the front bolster is journaled a sheave, Z, over which passes a cord or chain, a, one end of which is secured by a hook or otherwise to the bolt that passes through the doubletree, the strap plate and also the tongue being provided with a slot, m, as shown in Fig. 2.
The several parts of my device being constructed andcombined as above described, it follows that when the wagon is going downhill the bed and its contents will run forward upon the rollers a, as indicated by the arrowin Fig. 1, and in so doing throw the upper end of the short leverz' forward, and consequently the lower end, which is connected with the cross-bar l1, backward, and thus apply the brake-blocks to the periphery of each of the wheels with the requisite force-namel y, a force depending upon the inclination of the road and the weight of the load. I
It will be noticed that by the advance of the wagon-bed upon the bolsters the bolt in the doubletree is drawn back in the slot m. Consequently when the wagon regains level ground the application of the draft, which first acts upon the cord or chain it, returns the wagon bed to its former position, and in so doing removes the brakes from the wheels.
Having fully described rnyinvention; what I claim, and desire to secure by Letters Patent,
is I
In a wagon the bed of which is adapted to move forward by the gravitation of the load and thus apply the brakes to the wheels, as herein described, the combination of the sheave Z, slots min the tongue and strap-plate, and the cord or chain it, having one end secured to the front part of the wagon-bed and the other to the bolt or pin by which the doubletree is socured to the tongue, all of said parts constructed and adapted to operate substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 1st day of March, 1887.
THOMAS B. ELLIOTT.
