` Y UNrrnn STATES Y PATENT @Erica DANIEL S. LANE, OF HOOVERSVILLE, PENNSYLVANIA.

`WAGON-emma.

SPECIFICATION forming part of Letters Patent No. 288,456, dated November 13,1883.

Application filed March 29,18%. (No model.)

ToaZZ whom it may concern:

Beit known that I, DANIEL S. LANE, a citizen of the United States of America, residing at Hooversville, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Wagon- Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appcrtainsto make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

rIhis invention relates to automatic wagonbrakes, such as are set by the forward lurchving of the rear portion of the running-gear,

its object being to furnish a brake which will be automatically set on descending` grades, to prevent the wagon from running forward upon the animals, and relieved as soon as the level is reached or an ascending grade commenced, and which may be also readily locked off to permit the wagon to be back-ed.

The invention consists in certain novel constructions and combinations of parts, which will be hereinafter particularly described, and

" pointed out inthe appended claims.

In theaccompanying drawings, Figure 1 is a plan View of the running-gear of a wagon axle and the sand-board S, in the usual manner, and has an elongated slot,b, through which passes the king-bolt E, so that said front end of the coupling-pole may play forward and rearward between the sand-board and the axle. At about the middle of the coupling-pole, or at the junction therewith of the hind hounds, is mounted a transverse shaft, F, secured in suitable bearings, f, and having the lever-arm G projecting upward from its opposite ends l and rmly secured thereto. From the upper ends of these leverar1ns two pivoted rods, h, extend forward and are connected to a slotted plate, t', which is connected to the rear end of a bar, k, by means of a bolt which passes through said bar and the slot of the plate t'. The forward end of the bar k enters between the sandboard and the front axle, and is provided with a hole for the passage of the `king-bolt.

To intermediate portions of the lever-arms G are pivoted rods m, which extend rearward, and have their rear ends pivoted to eyes n, which proj ect from the front edge of the brakebar A.

To the front edge of the sand-board S is attached a rocking rod, It, supported in staples i', and bent outward from the center ofthe sandboard to form a loop or yoke, R.. i

To the outer end of the rod R is secured a vertically-projecting handle, t, which may be normally held in position by a spring-clip, t, attached to one of the front standards.

To thefront end of the coupling-pole is secured a hook, o, and by operating the redt the yoke or loop R may be thrown down to engage with this hook or raised out of the path of the coupling-pole.

The operation of my improved brake as now described is as follows: Zhen a wagon is travcling on a level or ascending grade, 'the coup-V ling-,pole slips rearwardly until the front wall of its slot bears on the king-bolt. The bar r, however, is not slotted, and therefore does not slip rearwardly, and thus, as the coupling-pole carries the shaft F and the lower ends of the lever-arms G rearwardly, the upper ends of said arms will be drawn forward bythe rods h and bar la, and, as a consequence, the rods m are caused to draw the brake-bar forward and remove the brake-shoes from the wheels, so that they are allowed to ru-n fre-ely. When, now, the wagon begins to travel on a descending grade,the coupling-pole and its connectgravity, and the rear wall of the slot in the coupling-pole will bear against the king-bolt. As, now, the shaft F and the lower ends of the lever-arms G are carried forward, the upper ward by the rods h to the position shown in dotted lines, Fig. 2, and the rods m are caused to drive the brake-bar rearwardly and press ends of said leven-arms will be thrown reared rear running-gear are thrown forward by i IOS) l 2SA56 the brake-shoes against the wheels, as' also shown in dotted lines. Of course, as soon as the level is reached or an ascending grade commenced and the rear running-gear lags, the wheels will be relieved of the brakes by the operation of' the parts, as hereinbefore described.

It will be observed that by adjusting the plate t' forwardly or rearwardly upon the bar k the throw of the brake-bar niay be varied7 to cause the brakes to press either heavily or lightly upon the wheels, as desired.

Vhen it is desired to back the wagon, the yoke or loop R must be thrown downward to engage the hook on the front end of the coupy ling-pole, so as to prevent said pole from sliding forward and operating the parts to set the brakes. Vhen the wagon has been backed sufficiently, the horses may be caused to move forward slightly, land the yoke may then be dis-v engaged from thehook, so th at the king-bolt will receive the draft of the coupling-pole.

Having now fully described my invention, and explained the operation thereof, I claiml. In combination with an automatic wagonbrake, a coupling-pole provided at its forward end with a hook adapted to engage with a pivoted loop attached to the sand-board, and provided with an operating-lever, and a catch for 3. In combination with the slotted coupling- 4o vbar B, provided at its forward end with a hook,

o, the brake-bar A. supported within bails upon the coupling-pole and rear hounds, pivoted connecting-rods m, transverse rocking bar F, with end arms, G, bars 7L h, united at their forward ends and provided with a slot, i, and rod ls, attached to the sand board S, said sandboard being provided with a pivoted loop, R, with operating-lever t, and means for holding said lever attached to the wagon-body, the parts being organized and arranged substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses. v DANIEL S. LAINE.v
