To all whom it Hwy] concern:

Be it known that IVINFIELD S. LIvnNeoon, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful lmprovements in egon-Brakes, of which the following is a specilication.

My invention relates to improvements in wagon-brakes; and one of my objects is to mount the brake-shoes in such a manner that when swungl to an inoperative position they will be carried free of the rear wheels and the mnd which usually accumulates thereon, and thus avoid needless wear by contact therewith. 1 attain this result by mounting the brakeshoes in such a way thatthey will swing' at an angle from the face of the wheels instead of in a direct line therefrom when thrown to an inoperative position.

A further object is to render the brake especially adaptable for bottom-dumping wagons. This object is accomplished by dispensing with the transverse shaft usually employed to carry the brake-shoes and mounting' the latter upon arms extending in an almost perpendicular position and pivotally mounted in brackets secured to the side-boards of the wagon-body.

1n order that the invention may be readily understood, reference will now be made to the accompanying drawings, in which-e Figure 1 represents a wagon provided with my improved brake. Fig. 2 is a broken plan view of the same. Fig. 3 is an enlarged transverse section taken on line 111 111 of Fig. Q. Fig. 1 is a modified form showing how the foot-lever is locked in an operative position. Fig. 5 is a plan view of the same.

-1n the drawings, 1 designates a wagon of the bottom-dumping pattern, consisting of side-boards Q, hinged doors 3, and carryingwheels i.

5 designates a pair of V-shaped brackets provided with integral ianges 6, whereby they are rigidly secured to the side-boards adjacent to the rear wheels. The central curved portion T of the brackets incline outwardly from their lower to their upper ends, and their upper edges S extend at right angles thereto a short distance to provide a bearingsurface for l washers 9, interposed between edges 8 and a shoulder 10 on the upper ends of a pair of arms 11, pivotally secured in the curved portions of the brackets by segmental bolts 12, which pass transversely through the brackets just in rear of said curved portions and with the latter complete the bearings for the arms 11. These bearings are inclined outward for two purposes, viz: Their upper outer ends stand su tlicientl y remote from the wagon-body to permit the operating-crank (described bclow) to have a movement above the bracket itself, whereby the crank is prevented from injury and cannot be struck by an adjacent object which would bend or break it. Also the inclined position of the bearing causes the brake-shoe (described below) to have a forward and upward movement away from the wheel when the brake is thrown ofi', as well as a move-ment inward toward the wagon-body, all combining' to draw the shoe out of a position where it might be struck and injured by an adjacent object. The lower ends 13 of arms 11 are turned outwardly in a horizontal plane for the reception of brake-shoes 11, pivotally mounted thereon and secured from lateral movement by Cotter-pins 15, extending through the outturned ends.

16 designates a pair of cranks rigidly secured at their outer ends upon the upper terminals of arms llv and pivotally secured at their inner' endsl to the bifurcated ends 1T ot' connecting-mals 1S, which latter are made in two parts :nljustably secured by turnhuckles 19, so the brake-shoes may be properly adjusted with relation to the rear wheels. The forward ends of the connectingrods are turned inwardly and pivotally secured to the free ends of a pair of cranks Q0, formed integral upon the opposite ends of a rock-shaft Q1, mounted in bearings Q2, secured to the forward ends of the side-boards. Rock-shaft Q1 is provided about midway between its crank ends with a. rigidly-secured foot-lever Q3, the downward movement of which latter is limited by a chain 24, secured at its opposite ends to the foot-lever, and a link 25, loosely embracing the winding-shaft 26 of the door-operating mechanism, in order that the rotation of said shaft will not alfect the foot- IOO lever. By providing chain 24 the foot-lever is prevented from being depressed suiiciently to carry the upper` forward ends of cranks 20 down below a horizontal plane, and thus render the brake inoperative, it of course being understood, however, that the several parts are so adjusted that the brake-shoes will be held in contact with the rear wheels with sufiicient pressure to lock the same before cranks 20 are depressed to a horizontal position.

In operation the brake-shoes are thrown out of contact with the wheels by drawing the foot-lever to its rearmost position, which movement rotates arms ll almost a quarter of a revolution, swinging the brake-shoes forward and to one side of the rear wheels, as shown by dotted lines, Fig. 2, so that when the latter are covered with mud it will not contact with or be deposited upon the brakeshoes, and thus interfere with their proper operation. The brake-shoes are reliably held in an inoperative position without the use of springs or notched segments by arms 11,which are drawn into suflicient frictional contact with the brackets by segmental bolts l2 to hold them in any position placed.

In the modified form (shown in Figs. 4L and 5) seat 27 islowered and moved forward, so the driver may place his feet upon a foot-rest Q8 instead of the front bolster 29.' The forward upper end of the foot-rest is provided with a transverse bar 30, arranged slightly below the horizontal plane of shaft 2l, s'o that when the foot-lever is depressed into contact with said transverse bar it will be held in contact with the latter by the downward and backward pull of the connecting-rods 18 until relevated by the driver. Consequently the brake-shoes may be held against the rear wheels without the driver constantly holding his feet upon the foot-lever.

From the above description it is apparent that I have produced a brake simple, strong, durable, and constructed and arranged in such a manner that it will not interfere with the movement of doors 3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a wheeled vehicle provided with a wagonbody,`upwardly and outwardly inclined brackets secured to the sides of the wagon-body adjacent to the rear pair of wheels,

arms swiveled in the brackets and having lower outturned ends, brake-shoes mounted upon said outturned ends, and suitable means for operating the arms so the brake-shoes may be thrown in or out of engagement with the wheels.

2. In a wheeled vehicle provided with a wagon -body, upwardly and outwardly inclined brackets secured to the sides of the wagon-body adjacent to the rear pair of wheels,

upwardly-extending arms swiveled in the brackets andhaving lower outturned horizontal ends, brake-shoes mounted upon said outturned ends, cranks rigidlyv secured to the upper ends of the arms and at right angles thereto, and suitable means for operating the cranks so the brake-shoes may be thrown in or out of engagement with the wheels.

3. In a wheeled vehicle provided with a wagon-body brackets secured to the sides of the wagon-body, adjacent to the rear pair of wheels and having upwardly and outwardly inclined bearings, upwardly-extending arms swiveled in the bearings and having lower outturned ends, segmental bolts holding the arms in place, brake-shoes suitably lmounted on said outturned ends, cranks rigidly secured to the upper ends of the arms, collars interposed between the cranks and the upper portion of the bearings, and suitable means for operating the crank-arms.

Llc. In a wheeled vehicle provided with :a wagon-body, brackets secured to the sidesof the wagon-body adjacent to the rear pair of wheels and inclined upward and outward, upwardly-extending arms swiveled in the brackets and having lower outturned ends,.brake shoes on the latter, cranks rigidly secured to the upper ends of the arms and projecting toward the wagonbody, adjustable connecting-rods pivotally secured at their rear ends to the inner ends of the cranks, a rock-shaft journaled at the forward portion of the wagonbody, cranks formed integral with. the opposite ends of said rock-shaft to which'the forward ends of the connecting-rods are swiveled, and a lever for operating said rock-shaft.

In testimony whereof I affix my signature in the presence of two witnesses.
