WAGON-BRAKE.

Specification of Letters Patent.

Patented. Jan. 29, 1907.

Original application filed May 2, 1905, Serial No. 258,449. Divided and this application filed April 18, 1906. Serial No. 312,445.

To all whom it may concern.-

Be it known that I, ENocH SMITH, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Wagon- Brakes, of which the following is a specification.

My invention relates to certain new and useful improvements in wagon-brakes which are particularly adapted for use in connection with dumping-wagons and the like, such as disclosed in my copending application, Serial No. 258,449, of May 2, 1905, and of which this application forms a divisional art.

Generically, my invention comprises a wagon-body to which a U-shaped member is fulcrumed, which member carries brakeshoes at each end for engaging the rear wheels of the wagon and a turn-post cooperatively connected with the U-shaped member through the medium of connecting-ropes, whereby the brake can be applied or loosened at the will of the operator.

WVith other objects in view than have been heretofore enumerated the invention also comprises certain novel construction and detailed arrangement of parts, all of which will be first described in detail and then be speci'lically pointed out in the appended claim, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a wagonbody of the type shown in my copending application hereinbefore referred to with my invention applied. Fig. 2 is an inverted plan view thereof. Fig. 3 is a detailed top planview of thefront end of the wagon. Fig. 4 is a cross-section on the line 4 4 of Fig. 1 looking in the direction of the arrow. Fig. 5 is a view of a slightly-modified construction hereinafter specifically referred to. 8

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the ligures, it will be seen that the wagon comprises a body 1, including the sides 2 2, the rear gate 3, and front wall or end 4.

5 5 designate cross-beams arranged to cross the wagon-body beneath the same, to which the wagon-body is secured by brace or stay rods or bars 5 5 as shown.

6 designates another cross-beam secured to the wagon-body by stay-bars and braces 6 '6 6 which beam 6 is secured to the rear axle 7 by any suitable means desired, braces 8 being provided to strengthen such connection.

A connection of this character is necessary to allow for the strains imposed when the brake is applied. Any suitable fifth-wheel connection can be made with the front axle beams, and any suitable front truck can be used with my wagon, as the same per se forms no part of my present invention.

In carrying out my invention a U-shaped rod 26 is pivotally mounted in bearings 26 26" on the wagon-body, and the rod 26 carries the brake-shoes 27 27 at its free ends, which brake-shoes 27 27 are adapted to engage the rear wheels W W of the wagon. Secured to rod 26 at a suitable point adjacent one of the brake-shoes is a cable 28, which passes over idler-pulleys 29 and 30 on one side of the wagon-body and connects with the brake-lever 22 at a point to one side of its pivot, as shown. A similar cable 28' is connected to the lever 22 at a point on the other side of the pivot and passes over idler-pulleys 29 30 on the other side of the wagonbody and connects with the rod 26 near the other brake-shoe. A brake-chain 23 connects with the lever 22, and the short chainrod 23' mounted on the wagon-body, as shown, which rod 23 carries a pinion 23', which meshes with a gear-wheel 24 on the brake-rod 24, as shown, and the brake-rod 24 carries a ratchet 24, that cooperates with a pawl 24 to hold the brake in its applied position, as shown, a suitable hand-wheel 25 being'attached to the upper end of the rod 24 to permit its manipulation.

Instead of using a cable 28 I may use rod and chain devices 28 28 28, as shown, although the latter devices are the equivalent of the cable devices shown. (See Fig. 5.)

From the foregoing description, taken in connection with the accompanying drawings, it is though the complete construction, operation, and numerous advantages of my invention'will be readily understood by those skilled in the art to which it appertains.

What I claim is In an apparatus of the class described, th combination with a wagon-body, of a U- shaped member pivotally supported in brackets beneath the wagon-bottom, brakeshoes secured to each end of said U-shaped member for engaging the wagon-wheels,
