BRAKE MECHANISM FOR VEHICLES.
SPECIFICATION forming part of Letters Patent No. 693,731, dated February 18, 1902. Application filed May 31, 1901. Serial No. 62,532. (No model.)
To all whom, it may concern:
Be it known that I, GEORGE F. MOORE, a citizen of the United States, residing at \Vest WVilkinsburg, in the county of Allegheny and State of Bennsylvania, have invented or discovered certain new and useful Improvements in Brake Mechanism for-Vehicles, of which improvements the following is a specification.
The invention described herein relates to certain improvements in brake mechanism for vehicles, and has for its object a construction of connections between the brake-lever and the shoes whereby the latter may be caused to exert any desired pressure upon the wheel regardless of the length of movement of the brake-lever.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure l is a side elevation of a wagon having my improved brake mechanism applied thereto. Fig. 2 is a sectional elevation, on an enlarged scale, showing the connection between the brakelever and the brake-rod; and Fig. 3 is an end elevation of said mechanism.
In the practice of my invention the brakeshaft 1 is secured to the body of the vehicle in any suitable manner and is provided with arms 2, having the shoes 3 secured to their outer ends. An arm 4 is also secured to the brake-shaft and is connected to one end of the rod 5. On the front end of this rod are formed a series of rearwardly-inclined teeth 6, and said portion is supported and guided in a box or frame 7, secured in any suitable manner to the wagon-box. It is preferred to pivot the lower end of the operating-lever 8 to a projection from the guide box or case 7. To this lever is pivotally connected a hook 9, extending back from the lever in such mannor that the hook will engage the teeth 6 on the brake-rod. The hook is held in engagement with the teeth 6 by means of a spring 10 or any other suitable means. As the lever 8 is pushed forward it will exert a pull on the rod 5 in the direction to cause the shoes 3 to press against the wheels. In order to hold the brake-rod in the position to which it has been shifted by the forward movement of the lever 8, while the latter is moved back to engage another tooth, a retaining-hook 11 is pivotally mounted within the guide case or frame 7 in such manner as to engage the teeth 6 in the rear of the point of engagement of the hook 9 with such teeth. The hook 11 is normally held in engagement with the teeth by means of a spring 12, as clearly shown in Fig. 2. It will be readily understood from the foregoing that by a repeated back-andforth movement of the lever S the shoes 3 can be caused to bear upon the periphery of the wheel with any desired pressure.
In order to release the shoes, the end of the hook 9 is extended and is so shaped that when the lever is drawn completely back the hook will be raised by means of a pin or abutment 14: so located that the hook 9 when moved back will strike against the pin or abutment and be raised up out of engagement with the teeth and caused to push the hook 11 out of engagement with the teeth 6, thereby releasing the pull-rod 5 and permitting the shoes to be shifted away from the wheels by means of a suitably-arranged spring 17. The teeth 6 and the hook 11 should be so arranged that the latter can be forced backward and upward by the rearward movement to full stroke of the lever S. In other words, the teeth and hook should be so constructed that even with an excessive pull on the rod 5 the hook will not be held except by friction as against release by the movement of the lever B.
It will be observed that the hooks 11 and 9 are so pivoted with relation to the direction of pull on the brake-rod 5 when the brakes are applied that a pull in contradistinction to a thrust is exerted on the hooks and their pivot-pins. In other words, the hooks extend from their pivot-pins rearwardly or in the direction of pull on the brakerod, so that when the hooks swing on their pivots they will move in planes parallel with the under faces of the teeth 6, which also project rearwardly. This movement can only be effected by so arranging the mechanism that the hooks when in operation are in tension, as stated.
I claim herein as my invention 1. A brake mechanism for vehicles having in combination, a rod connected at one end to the brake-shaft, a series of rearwardly-projecting teeth connected to said rod, an operating-lever, a hook mounted on the lever and adapted to engage said teeth, and a retaining-hook adapted to engage said teeth, said hooks extendingrearwardly or in the direc tion of pull on the brake-rod from their pivotal supports, substantially as set forth.
2; a A brake mechanism for vehicles having in combination a rod having one end connected to the brake-shaft, a series of rearwardlyprojecting, teeth connected to said 7 rod, a brake-lever, a hook pivotaliy mounted on the lover, a pivotally-mounted retaininghook, and 'a pin or abutment for forcing the lever-hook against the retaining hook and forcing the latter out of engagement with the teeth on the pull movement of the lever, substantially as set forth.
In testimony whereof I have hereunto set my hand.
GEORGE F. MOORE.
