IMPROVED WAGON-BRAKE. --4.

The Schedule referred to in these Letters Patent and making part of the lame.

T 0 all whom it may concern Be it known that we, GEORGE WESLEY WELsH and GEORGE WYLHJ, of Arlington, in the county of Oolumbia, and State of Wisconsin, have invented a new and improved Wagon-Brake; and we do hereby declare that the following is a full, clear, and exact descrip-- tion thereof, which will enable others skilled in the art to malge and use the same, reference being had to the accompanying drawings, forminga part of this specifi-' cation. 1 Y v This invention relates to a new and improved automatic brake for wheel-vehicles and It consists in the arrangement of the parts of the brake with relation to the wheels, the hounds, and the bolt for attaching the pole to the hounds, as will be hereinafter more fully described.

In the accompanying sheet of drawings- Figure 1 is anoinverted plan of our invention;

Fi'gure 2, a side sectional view of the same, taken in the line as w, fig. 1.

Similar letters of reference indicate correspondingparts.

A represents an axle, having awheel, B, fitted loosely on each end.

I C G are hounds, between the front ,ends of which the draught-pole D is secured by a bolt, E, as usual. These parts being of ordinary construction, donot require an extended description.

The bolt E, of the draught-pole, has secured upon it a rod, G, which is bent in such a form as to have V a central pendent projection, a, extending below the draught-pole, the rod G being fitted on the bolt E in such a manner that it may turn freely thereon.

To, the lower end of the projection to, a rod, H, is attached, which extends along, underneath the draughtpole, to nearly the front end of the same, where it is formed or provided with a loop or ring, I), which is fitted and allowed to move freelyback and forth on the draught-pole.

Tothe ends of the rod G there are attached arms,

I' I, which extend back through suitable guides, c, to a.

shaft, J, the latter having a shoe, K, at; each end of it, said shoes being at the rear of thewheels B B, and in line with the same:

' The shaft J has spiral springs, d d, upon-it, which springs have a tendency to keep the shoes pressed towards'the wheels, the shaft J'being allowed to turn in the rearcnds of the arms I I.

; The'lioldback straps of the team are attached to the front end of the rod H; and it will be seen from the above description, that when the vehicle is descending an eminence, and the team checked, forward movement of the vehicle will apply the brakes, and the shoes K are below the centres of the wheels, so that the latter will have a tendency, as they rotate, to bind the shoes against them.

In case of backing, however, the shoes'will not press against the wheels, the retrograde movement of the latter having a tendency to throw the shoes out from the wheels, as indicated in red.

This very simple arrangement of parts, constituting a self-acting brake, may be applied to almost any of the known forms of wheel-vehicles in use, and at a very moderate expense.

Having thus described our invention,

What we claim as new, and desire to secure by Let- .ters Patent, is-

The arrangement of the bent rod G, having the pendent portion a,'the arms I I, shaft J, shoes K, spiral springs (land rod D, with relation to the bolt E, the
