AUTOMATIC WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 627,645, dated June 27, 1899. Application filed January 23, 1899. Serial No. 703,150. (No model.)

T to whom it mag concern:

Be it known that I, LOUIS J. KLEIN, a citi- 'zen of the United States, and a resident of Bairdstown, Sullivan county, State of Missouri, have invented certain new and useful Improvements in Automatic Wagon-Brakes;

and my preferred manner of carrying out the invention is set forth in the following full,

' clear, and exact description, terminating with tongue or pole by which the vehicle is drawn. I

claims particularly specifying the novelty.

This invention relates to brakes for carriages and Wagons, and more especially to that class thereof known as automatic brakes; and the object of the invention is to produce means for holding such a brake off the wheels when desired, as in backing.

To this end the invention consists in the specific details of construction hereinafter more fully set forth and as illustrated in the accompanying drawings, wherein-- Figure 1 is a bottom plan view of a wagon constructed in accordance with my invention. Fig. 2 is a central longitudinal section of the same, showing the hook in use in the act of locking the brake against application to the wheels.

Referring to the said drawings, the letter B designates the body of the carriage or wagon, (here the latter, having the usual runninggear, with wheels W and axles A, and P is the It is obvious that the same might easily be a pairof thills, so that the whole could be drawn by a single animal without departing from f the spirit of my invention, and for this rea- 1 son the same is'not herein illustrated.

Coming now moreparticularly to the present invention, 1 is the brake-beam, having shoes 2, as usual, adjacent therear wheels, and this beam is supported in any approved manner, asby chains or 1inks3. 4 is a pulley on the rear axle, over which passes a cord, rope, chain, or strap 6, leading from the center of said brake-beam. Thence it preferably passes along between the hounds 7, under a pulley Son the front axle, along beneath the tongue P, branches at 9, leads under pulleys 10 on said tongue, and finally extends upward,-as at 1 1, and isv attached to the polestrap of the team of horses in a manner which will be clearly understood. By this construction in descending a hill or when the horses are pulled forcibly to v,the rear by the driver the strap 6 is drawn upon, and by its arrangement with respect to the several pulleys shown it draws the brake-beam to the rear and applies the shoes against the rear wheels, the force of application being more powerful as the team is more forcibly reined in or backed. For this reason a lady or timid" person can well drive a team attached to a vehicle provided with this improved brake, as there is little danger of accident in descend 'ing' hills; but there are numerous devices in use for the automatic application of the brakes under similar conditions, and the chief merit of my present invention consists in the means I employ for preventing the application of the brakes when their use would destroy the object to be attained-as, for instance, when it is intended to back the team. To this end, 20 is a beam pivotally supported at its forward end, as at 21, beneath the wagonbody and sustained in its normal or elevated position by a spring 22, preferably also connected with said body. At its rear end depend rods, bars, or prongs, (two in number,)

which constitute hooks 23, so located as to pass down in rear of the brake-beam when the beam 20 isdepressed at its rear end, while said brake-beam stands forward. For this purpose any suitable mechanism may be employed, although'in the present instance I have shown a rod 25, passing downward through the bottom of the body, resting at its lower end on the'pivoted beam 20 and provided at its upper end with a foot-piece 26.

- The driver when it is desired to back the team or for other reasons it is undesirable that the brake shall be applied has but to place his foot on the foot-piece 26 and press the same, so as to engage the hooks 23 in front of the brake-beam 1, and the object is attained.

I have not illustrated herein the modifications necessary to adapt the present-invention to a one-horse vehicle-because such modifications are obvious, as also are those changes which will readily appear to the skilled manufacturer and all of which come within the spirit of my invention. For instance,a spring 30 may be employed to normally throw the construction will be apparent.

\Vhat is claimed as new is 1. In an automatic brake, the combination with the runninggear, brake beam, and shoes; of a strap connected with the horses collar and led over pulleys to said beam so as to apply the brake when the horse is drawn in, upright hooks depending in position to pass in rear of the brake-beam when the lat-- ter stands off the wheels, and means for depressing said hooks at will, as and for the purpose set forth.

2. In an automatic brake, the combination with the running-gear, brake-beam, shoes thereon, and a spring for holding the latter normally oil the wheels; of means for applying the brake when the horse is drawn in, a
