WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No.' 278,948, dated June 5, 18B3,

Application filed April 5, 1883. (Model.)

To all whom it may concern: y

Be it known that I, FRANoIsHARTnR, a citi zen ofthe United States, residing *at Wvilkes- Barr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Tagen-Brakes, and I do declare the following to' be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let-ters and figures of reference markedA thereon, which form a part of this specification.

My invention has relation to improvements in wagon-brakes, and it consists in the construction, combination, and arrangement of the several parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a front view, and Fig. 2 is a vertical longitudinal section, of a section of a wagon having my brake mechanism applied thereto.

The wheels a a. are spindled on the ends of axle A, which is preferably secured or connected to the wagon-platform by springs, Sac., substantially as shown. Bars b b are pivoted to the axle near the inner ends of the hubs of the wheels, and are carried forward to a point somewhat in advance of the wheels, and are hinged to the lower ends of bars c c, the upper ends of which bars are pivoted or hinged on the platform-bar d.

The brake-shoes c are secured on the opposite end of a rod, e', and rest against the'wheels, as shown. Then so desired, these shoes may have a slight turning or rocking movement on the rod, so that they will readily adapt themy selves to the periphery of thewheel. Connecting-rodsff are fixed to the rod e', and extend forward, and are coupled or hinged to the bars,` b c at the hinge-joint of the latter, as shown, .thus forming a connection lbetween the rods b c and the brake-rod, and furnishing a support for the latter. It will be seen that the brake-rod e extends across from wheel to wheel, and that I employ two each of the bars b c and connecting-rods f, arranged on opposite sides, as shown. In order to hold the brake-shoes against or away from the wheels and to regulate the force of bearing thereof, I employ the lever y, which is pivoted in a suitable bracket or other support connected to the framing, and its lower end is connected with the brake-rode, at about the middle thereof, 55

by the pitnian h, so that as thelever r/ is operated the brakeslfoes will be held against the wheels, as shown in full lines, or away y therefrom, as indicated in dotted lines, Figi).

This lever may be operated by means of the 6o rod i, connected to its upper end, and extended forward and provided with the handle t", or other operating means may be employedsuch, for instance, as a chain might be secured to the upper end of the lever g, and car- 65 ried forward and iliade fast to a foot or hand lever arranged in reach and under .the control ofthe driver. In the ordinary brakes used on spring-wagons the brakes are usually supported from the 7o the same position when the wagon is loaded as So when it is not, and arranged to bear at alll times on about the same portion of the wheels. The brake-shoes, it will -be seen, are held at a point above the'bnlge of the wheels, so that as the latter are revolved there isa kind of S5 wedging action which aids in the braking operation, lenabling the brake to be strongly applied with but little exertion on the part of the driver. The brake being also connected with or mainly supported by the axle, the springs 9o are relievedfrom all strain.

It will be understood that in the drawings I haveonly illustrated onethe rear half of a wagon, that being the portion to which the brakes are ordinarily attached.

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

l. In a wagon-brake, the combination, substanti ally as described, with axle and the brake 1 oo By the connections and 7 5 y their opposite endshinged, respectively7 to Ithe axle and to the platform-bar, the Connectingrodsff7 having one end'seeured to `the brakeshoes and their other ends pivotallyv secured on the hinge-joint between the rods b c, the lever y, the piti'nan 71, and means for operating the said lever, snbstantiall)V as specified.

2. ln a wagon-brake, the combination ofthe brake-shoe arranged to bear on the wheel at a point above a horizontal line drawn through the axis thereofA` and a bar pivoted to and eX- tended from the axle forward beyond the wheel, and providing a pivotal support for the brake` shoe at a point in advance of and below the bearing-point thereof, whereby a wedging action of the brake-shoe is obtained7 and the rod wenn@ 7U, having one end pivoted to the rod e and eX 'tended rearward7 with its otherend secured to the operating mechanism7 all arranged to operate substantially as specified.

3. In a wagon-brake7 the combination ofthe rods b e, hinged together and supported sub stantially as described, the brake-shoes snpported on a suitable rod7 and the connectingrodsj'7 and means for opera-ting the brake7 all arranged and operating substantiallyv as and for the purposes set forth.

In testiinon)Y whereotl I aix my signature in presenee ot' two witnesses.

FRANCIS HARTER.
