IMPROVED WAGON -BRAKIL TO ALL WHOM IT MAY CONGERN:

Be it known that I, HUGH DAVIDSON, of New Salem, in the county of Pike, and State of Illinois, have invented a new and useful Improvement in Wagon-Brakes and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of thisispecication, in which- Figure 1 is a vertical longitudinal section of a wagon, to which my improved brake has been attached.

Figure 2 is a top or plan view of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved automatic brake, which shall be so constructed as to adjust itself properly to all positions of the wagon, which can be easily and cheaply made by any blacka smith, which shall be more durable than other brakes now in general use, and which shall be capable of being 'applied to any wagon.

And it consists in the construction ot the various parts of the brake, and in their combination with each other and with the running parts of the wagon, the whole being constructed and arranged as hereinafter more fully described.

A is a cap or tube, fitting upon the forward part of the tongue B, and the longitudinal movement of which may be limited by stop-pins attached'to the said tongue.

In the upper side of the rear end of the cap A is formed a hole, into which hooks a hook formed upon the forward end of the bar C.

The bar Gis formed of half-round iron, is secured to the upper side of the tongue B by two or more sta@ ples, one being placed near each end. p

Upon the rear end of the bar G is formed a hook, which hooks into a hole formed in the `forward end of the sliding'plate D.

The plate D has a hole formed in its central part, into which fits the doubletree-bolt or hammer-handle, and upon its rear end are formed two hooks that hook into holes in the forward ends of the two bars or plates E.

The bars E should be sufliciently far apart to receive the hammer-strap F between them, and to be unimpeded in their movements by said hammer-strap.

The hammer-strap F and the rear partof the tongue B must be slotted to receive the doubletree-bolt or hammer-handle, so that the said bolt or hammer may move forward and backward with the movement of the plate D.

The rear ends of the bars E should have eyes formed-in them to receive the bolt G, by which they are secured to the upper ends of they or devis-shaped lever H, the arms of which pass up upon each side of the rea-r end of the tongue B, and are secured in place by the'bolt I, by which the tongue B is secured to the hounds J.

The lower or horizontal part of vthe lever H is rounded off to receive the hook formed upon the forward end of the rod or bar K.

The part of the lever H above the bolt I, in an ordinary wagon, should be about six inches long, and the part below said bolt should be about three inches long.

The rod or bar K passes back beneath the forward axle L, and has a slot or loop formed in its rear end, through which the king-bolt M passes, and the said rod is held up or supported by a washer and key attached to the lower end or point of said king-bolt.

N is a rod, which has a hook formed upon its forward end, which hooks upon the rear or slotted end of the bar or rod K, and which has a hook formed upon itsV rear end, which hoetks upon the lower or horizontal part of the U or clevis-shaped lever O..

The lever O is similar in construction to the lever H, and is pivoted with its long end downward, in the :Position shown in iig. 1, to the forward end of the'plate P, which is adjustably secured to the reach Q by a bolt passing through said reach and through a slot' formed in said plate, so that the brake may be adjusted nearer to or farther from the wheels, as may be desired.

The arms of the lever O pass up upon each side of the reach Q, and have eyesor holes formed in them for the reception of the bolt R, by which the said lever is connected to the brake-bar S.

The brake-bar S vrests upon the reach Q, and upon the rear hounds T, which should be made as long 'as possible, so as `tcp/better support the said brake-bar.

U are eye-bolts, passing throughl the brake-bans in such positions as to fit upon the outer sideofthe upper ends of the lever O, to which they-are connected by the bolt R, thus forming a hinge for the brake-bar S to work upon.v l

V are the'bralie-shoes, which are madeand attached to the brake-bar S in theordinary manner, except that they should not descend below the said bar so as to allow the bar to turn up when backing the Wagon, and thus reiievelthewheels from the pressure of theb'rake.

In using this brake, as soon as the wagon presses forward against'the horses, the action of the neck-yoke upon the vcap A causes the brake to be applied to the wheels with a force proportioned to the forward pressure of the wagon.

In backing the wagon, the pressure of the neck-yoke forces the brake back, but the reverse movement 'of the wheels lifts the brake-bar, so that no pressure is applied to said wheels. f

I claim as new,.and desire to secure by VLetters Patentp i 'The arrangement, herein shown and described, of the brake-bar S, slotted plate P, U-shaped levers O H,

connection N, rod K formed: with an eye, at its rear end, bolt G, arms E, slottedplate D formed with hooks,

slottedstrap F, rod C having a hook at each end, and sliding sleeveA, all constructed asl described, and

arranged with relation to the reach Q, king-bolt M, and pole B, to operatefas set forth.

HUGH DAVIDSON.
