WAGON-BRAKE SPECIFICATION forming part of Letters Patent No. 309,125, dated December 9, 1884.
Application filed August- 528, 1854.
To @ZZ whom it may concern:
Be it known that I, CHARLES F. BEsr, a subject of the Queen of Great Britain, residing at Queens, in the county of Queens and State of New York, have invented new and useful Improvements in W'agon- Brakes, of which the following is a specification.
' My invention relates to improvements in devices for operating the brakelheads of wagons and other vehicles; and it consists in the combination, with a brake-head and its connection with the' brake-rod, of a hand or foot lever, a socket formed on said lever, a brakerod lever, and a knuckle formed on said lever and iitting the socket in the hand or foot lever.
This invention is illustrated in the accompanying drawings, in which Figure l is aside elevation of my improved brake mechanism. Fig. 2 is a front elevation of the same. Fig. 3 is a perspective view of a wagon provided with the same.
Similar letters indi cate co rrespondi ng parts.
The letter A indicates the frame to which part of the brake mechanism is attached, said frame being secured to the dash-board of the wagon. B is the hand or foot lever, pivoted to the frame A by the bolt or pin a. c is a socket formed in the lower end of the hand or foot lever B. C is the brake-rod lever,pivoted to the frame A by a bolt or pin, ci, and formed with a knuckle, e, on its upper end, which enters the socket c in lever B. The lower end of the brake-rod lever C is connected with the brake-rod D by the pin or bolt j'.
As shown in the drawings. the brake-rod D is extended to and connected with two levers, f/ g', suspended from the wagon-body by bars 7L h', and connected directly with the brakeheads t' i', both levers g g being moved at the same time by motion, as of the brakerod D. Instead of this arrangement, the brake-rod D may connect with an intermediate lever which is connected with a single brake -head by means used in the ordinary construction and arrangement of such connections.
In the accompanying drawings the full lines represent the relative positions of the levers B C and the brake-rod D when the brake-heads t' t" are applied to the wheels, and the broken lines show the saine when the brake-heads z' i are drawn off the wheels.
(No model.)
In the operation of the brakes, when the hand or foot lever B is moved forward, the front wall of the socket c engages the knuckle f on the brake-rod lever C, causing the said lever C to be moved to an extent required for throwing the brake-head t' z" upon the wheel.
Then the hand or foot lever B is moved backward, the back wall of the socket c engages the knuckle E, and the brakefrod lever D is moved to an extent required to remove the brake-heads z' i from the wheels.
If desired, the effect of the relative backward and forward motions ofthe hand or foot lever B may be reversed--that is to say, by moving thelever B backward the brake-heads t t" may be applied,and by moving the same forward they may be removed from the wheelssuch an arrangement being more convenient when the lever B is operated by hand.
VThe object of this invent-ion is to secure brake mechanism which is exceedingly sim ple in its construction and at the same time safe and durable.
Heretofore a brake mechanism has been composed of a plate to which is pivoted a footlever having at its lower end a pin engaging a longitudinal slotin the upper end of a brakerod lever, also pivoted to said plate and connected at its lower end to the brake-rod. My invention differs from such prior construction, in that I form a solid knuckle on the upper end of the brake-rod lever, which knuckle is received into a socket formed within the lower end of the foot or hand lever, whereby a stronger connection of the parts is provided.
XVhat I claim as new, and desire to secure by Letters Patent, ism
The combination of the brake-rod D and the pivoted brake-rod lever C, having the solid knuckle e formed on itsuppier eXtremity,with the pivoted lever B,having the socket c within its lower end, which receives the knuckle on the upper end of the brake-rod lever, substantially as described.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
i CHARLES F. BEST.
