UNITED STATES PATENT SAMUEL lV. HYATT, OF GREERSVILLE, OHIO, ASSIGNOR OFu ONE-HALF TO' JOI-I N W. MONINGER, OF SAME-PLAGE.
BRAKE-LEVER.
SPECIFICATION forming part of Letters Patent No. 651,997, dated J' une 19, 1900. Application filed December 6, 1899. Serial No. 739.377. (No model.)
To all whom, t may concern:
Be it known that I, SAMUEL WV. HYATT, a citizen of the United States,residing at Greersville, county of Knox, and State of Ohio, have invented certain new and useful Improvements in Brake-Levers; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.
This invention relates to improvements in brake-levers; and the object is to provide a strong and durable lever which may be quickly and easily moved to release the brake and to so construct the same that the parts may be readily adjusted as they wear from use.
The invention consists in the details of construction which are fully described in the following specication,particularly pointed out in the annexed claims, and clearly illustrated by the accompanying drawings, in which- Figure l is a perspective View of myinvention, showing the lever'locked. Fig. 2 is a vertical sectional view on`the`line2 2 of Fig. 1. Fig. 3 is a side elevation showing the lever released.
Referring now more particularly to the accompanying drawings, A is the ratchet-bar, which is bolted at its respective ends to the angle-iron B, which bolts pass through the sides of the wagon. The teeth of this ratchetbar are formed in the under edge thereof, as illustrated. Pivoted at its lower end to the angle-iron B is a short leverO, the securingbolt of which also passes through the wagonbed and secures said iron thereto'. The rod D, which is connected with the brake mechanism, is pivotally attached to said short lever intermediate the ends thereof. Lever O is bifurcated at its upper. end, the bifurcations eXtending on the respective sides of the ratchet-bar.
Pivoted between the bifurcations of lever O at a point below the ratchet-bar is a gravity-dog E, which engages the teeth of said ratchet-bar.
Pivoted adjacent to its lower end between the bifurcations of lever C at a point above the ratchet-bar is the operating-lever F, the lower portion G of said lever extending along .the brake.
the front side of the bifurcated portion of lever C and bearing flatly against the same when the lever is moved forwardly to apply This portion G of said operatinglever is bifurcated to receive the dog E, which extends therethrough and is formed with lugs H on its lower end to prevent said lever slipping therefrom when the former is moved rearwardly to release the brake. The lower end of lever F is formed' with a guiding-'lug l, which extends between the bifurcations of lever C and guides lever F in its movement and prevents the same from binding the dog E and preventing the easy working thereof. The lower end of operating-lever F is formed with a threaded aperture receiving the dogoperating bolt J, which is thus adjustable in said lever and which engages the bottom side of the dog. By making this dog-operating portion of the lever adjustable the same may be quickly and readily adjusted when the lever is attached to the wagon and thereafter as may be necessary as the parts wear.
The operation of myimproved brake-lever is as follows: When it is desired to apply the brake, the operating lever is moved forwardly, the lower portion G of the same engaging lever C, so that both levers move together, the gravity-dog engaging and riding over the teeth of the ratchet-bar. By having the-lower portion of lever F engage lever C for quite a considerable distance a large bearing-surface is provided and the construction thus rendered very strong. To release the brake,.the operatinglever is moved rearwardly, the same moving on its pivot and separating from lever C. As the lower end of the operating-lever moves forwardly and upwardly, as illustrated in Fig. 3, the adjustable bolt .I raises the lower end of the dog and disengages its engaging end from the teeth of the ratchet-bar. The lever C is then free to move to release the brake, and when this is accomplished the dog by gravity again engages the teeth of the ratchet-bar.
From the above description it will be seen that I have provided a very simple brake-lever which is effective in operation and strong and durable in construction and also means for adjusting the operating parts as they wear.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the'UnitedStates, is-' l. In a brake-lever, the combination with a ratchet-bar, of a lever pivotally supported'at its lower end and carrying a dog intermediate 1ts ends engaging said ratchet-bar, and an op and disengage the dog from the 'teeth of the ratchet-bar when moved in the reverse direction, substantially as described. l
2. AIn a brake-lever, the combination With a ratchet-bar, ofl a lever pivotally supported at one end and carrying a dog intermediate its ends engaging the teeth of said ratchet-bar,
, and an operating-lever pivoted intermediate its ends to said dog-carrying lever at a point above said dog, said operating-lever when moved in one direction adapted to disengage said dog from the teeth of the ratchet-bar and limited in its reverse movement by the abut- I ting of that portion thereof below its pivotal point against the front edge of the dog-carrying lever, substantially as described.
3. The combination WithV a ratchet-bar, of a levei` pivotally supported and carryinga dog engaging the ratchet-bar, an operating-lever pivoted to the first-mentioned lever,l and an adjustable engaging portion carried by said operating-lever and adapted to eect the disengagement of thedog from the teethof the ratchet-bar When the operating-lever is moved in one direction, substantallyas described.
4. The combination with a ratchet-bar, of a lever pivotally supported and carrying a dog engaging the ratchet-bar, an operating-lever pivoted to the irstmentioned4 lever, and an adjustable bolt carried by said operating-lever and engaging said dog, substantially as described.
5.. The combination with a ratchet-bar, of a lever bifurcated to receive said ,ratchet-bar and having a dog pivoted in said bifurcated portion engaging said ratchet-bar, an operating-.lever pivoted to said first-mentioned lever and bifurcated to receive said ratchetbar, said dog extending through the bifurcated portion of said operating-lever, and an adjustable bolt carried by said operating-lever and engaging the dog, substantially as described.
In testimony whereofV I aflix my signature in presence of two witnesses.
