WAGON-BRAKE.
SPECIFIGATION forming part of Letters Patent No. 464,404, dated December 1, 1891.
Application filed April 15, 1891. Serial 110. 389,115- (No model.)
To all whom it may concern.-
-Be it known that I, HENRY M. WELTY, a citizen of the United States, residing at Farmington, in the county of St. Frangois and State of- .Missouri, have invented a new and useful Brake, of which the following is a specification.
The invention relates to improvements in automatic brakes.
The object of the'present invention is to provide a simple and inexpensive brake adapted to be automatically operated by the body of the vehicle to apply the brake when the vehiicle is descending a hill or incline.
The invention consists of the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure 1 is a perspective View of a running-gear provided with a brake constructed in accordance with this invention, the body of the vehicle being removed. Fig. 2 is a reverse plan view, the body being in position. Fig. 3 is a central vertical longitudinal sectional view. Fig. 4. is avertical sectional view on line w x of Fig. 3. Fig. 5 is a similar view on line y 'y of Fig. 3.
Referring to the accompanying drawings, 1 designates a runningear having its reach 2 provided with a longitudinal slot 3 and adapted to slide between the rear hounds 4. and in the opening of the rear axle and bolster, and adapted to engage the lower end of a lever 5, which is mounted on the front ends of the rear hounds and is pivoted between angle-plates 6. The upper end of the lever is attached to the front end of a V-shaped connecting-rod 7, which has its rear end attached to the upper ends of levers 8, fulcrumed on the front face of the rear axle 9 and having their lower ends connected by rods 10 to the brake-bar 11, whereby when the rear hounds move forward on the reach the lower end of the lever 5 is carried rearward and the upper end is thrown forward, carrying with it the upper ends of the levers 8, which draw the brake-bar rearward and carry the brake shoes or blocks into engagement with the wheels. The brake-bar 11 is suspended by a link 12 from the end of a beam 13, secured to the upper faces of the rear hounds and extending beyond the same, and the rear vertical levers 8 are fulcrumed intermediate of their ends between eyes 14, projecting forward from the rear axle.
The body 15 of the vehicle is secured by cross bars or cleats 16 to the rear bolster and it rests loosely on the front bolster between the standards thereof, and when the vehicle is descending a hill or incline the body is thrown forward by its own weight,-and it carries with it the rear axle and hounds, thereby applying the brake, and the steeper the hill or incline the greater is the force with which the brakes are applied. The front bolster is provided near its ends with rollers 17, which' are journaled between upturned ends of plates 18, and the rollers facilitate the movement of the wagon-body and enable the same to readily apply the brake. The body 15 is provided on its bottom near its front end with wear-plates 19, which are adapted to be engaged by the roller 17. The body is held back and the brake kept from the Wheels by a rock-shaft 20, which is journaled on the bottom of the body near the front end thereof, and is provided with an arm 21, arranged to engage the front'bolster 22. The outer end of the rock-shaft is provided with a handle, which is arranged in a keeper and which operates the rock-shaft.
It will be seen that the brake is simple and inexpensive in construction and is capable of being automatically operated by the vehicle, and that the steeper the hill or incline themore effectually the brake is applied.
The connecting-plate 26 of the rear hounds is provided with an opening 27 to receive the lever 5, and the latter has its lower end pivoted in the opening of the reach. The reach is capable of a limited longitudinal move ment sufficient to operate the brake.
That I claim is 1. The combination, with a running-gear having its rear axle and hounds sliding on the reach provided with an opening, of the vertically-disposed lever 5, pivotally'mounted on the hounds and having its'lower end engaged by the opening of the reach, the brake-bar, and the vertical levers 8, fulcrumed intermediate their ends on the rear axle and connected with the brake-bar and with the lever 5, substantially as described.
2. The combination, with a running-gear having a sliding reach provided with an opening, of' the vertically-disposed lever 5, pivotally mounted on the rear hounds and having its lower end engaged by the opening of the reach, the brake bar suspended from the hounds, the vertical levers 8, pivoted intermediate their ends and connected with the rear axle, the rods 10, connecting the lower ends of the levers with the brake-bars, and the V-shaped connecting-rod having its front end attached to the lever 5 and its rear end secured to the upper ends of the levers 8, substantially as described.
3. The combination, with a running-gear having its rear axle and hounds sliding on the reach and the latter being provided with an opening, of the angle-plates secured to the body secured to the rear bolster and loosely mounted on the front bolster, substantially as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in 30 presence 0t two witnesses.
