VEHICLE BRAKE.
UNITED STATES PATENT OFFICE.
ARCHIBALD B. MCNEIL, OF SIOUX CITY, ICI/VA.
VEHICLEQBRAKE.
SEECIFICATION forming part of Letters Patent No. 505,903, dated October 3, 1893.
Application filed April 29,1893. Serial No. 472,345. (No model.)
To all whom it may concern.-
Be it known that I, ARCHIBALD B. MCNEIL, a citizen of the United States, residing at Sioux City, in the county of Woodbury and State of Iowa, have invented a new and useful Vehicle-Brake, of which the following is a specification.
The invention relates to improvements in vehicle brakes.
The object of the present invention is to simplify and improve the construction of automatic vehicle brakes, and to enable the same to be readily arranged for backing.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated l in the accompanying drawings and pointed out in the claims hereto appended.
In the drawings-Figure 1 is a plan view of a running gear embodying the invention. Fig. 2 is a central vertical longitudinal sectional view. Fig. 3 is a detail perspective View of the depending lever. Fig. 4 is a detail sectional View illustrating the manner of fulcruming the brake levers.
Like numerals of reference indicate corresponding parts in all the figures of the drawings.
1 designates a transverse bar secured to the rear hounds of a running gear and having fulcrumed on its ends brake levers 2 extending longitudinally of the transverse bar and carrying brake shoes 3 at their outer ends, and provided at their inner ends with forwardly extending clevises 4 which are connected with a draft cable 5. The draft cable 5 extends forward from the brake levers to the front end of the tongue 6, and passes around the pulley 7 and is secured by a bolt 8 to a neck yoke 9, whereby when the running gear moves forward on the draft animals, the cable will be drawn around the pulley, thereby moving the inner ends of the brake levers forward and applying the brakes. As soon as the draft animals move forward, the wheels are relieved of the brake. The pulley 7 is arranged in a keeper 10, and the cable passes through a guide eye 11 and through perforations 12 and 13 of a depending lever 14. The depending lever 14 is Y-shaped, and receives between its arms, the tongue 6 to which it is pivoted; and the cable in advance of the lever 14, is provided with an eye 15, and a hook 16 which form when in engagement with each other a slack loop 17 adapted to be let out to lengthen the cable, to permit the running gear to be backed without an application of the brake. The cable 5 is lengthened sufficiently by this means to prevent the draft-animals from drawing ou it in backing the vehicle and thereby prevent an application of the brake. The loop and hook of the cable should be arranged sufliciently near the keeper 10 to cause the hook, when disengaged from the loop, to form a stop to prevent the cable from being drawn through the keeper sufficiently to apply the brake and to enable the vehicle to be backed, as the neck yoke will then be positively connected to the tongue r pole, and no strain on the cable Will apply the brake.
Wear plates 18 are interposed between the brake levers and the transverse bar, and the parts are supported by yokes 19. The brake levers are held out of engagement with the Wheelsby a spiral spring 20 having its front end connected to the clevises, and its'rear end secured to the hind bolster.
It will be seen that a simple and inexpensive automatic brake is provided, and that it may be readily arranged to permit backing without an application of the brake. v Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
1. The combination with a running gear, a transverse bar secured to the rear hounds, brake levers fulcrumed on the transverse bar and provided at their outer ends with brake shoes, a pulley arranged at the front of the tongue, and a cable passing around the pulley and connecting with the brake levers and provided with a hook and au eye arranged apart whereby a slack loop may be provided to increase the length of the cable for back ing, substantially as described.
2. The combination with a running gear, of a transverse bar secured to the rear hounds, brake levers fulcrumed on the transverse bar and provided at their outer ends with brake IOO shoesand having elevises at their inner ends, a depending Y-shaped lever fulerunied on the tongue and provided with perforations, a pulley arranged at the front of the tongue, a cable connected to said clevses and passed through the perforations of the lever of the tongue and extending around'said pulley to be connected with the neck yoke and provided with a hook and an eye forming a slack 1o loop, and a spring connected with the brake levers to hold the shoes 0E the wheels, substantially `as described.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of tWo witnesses.
ARCHIBALD B. MCNEIL.
