KLASNIOK, a

' Roundup, in the countyot liliisselshell and State of lli/lontana, haveinvented new and useful linprovernents in Gar-Brakes, of

which the following is a specification.

The general object of the invention'is vto simplify the construction of car brakes and to admit of the application' of these devices in a minimum of timeand with a minimum of eiiort on the part of the operator.

@ther objects will appear and be better understood from theA following description taken in connection with the accompanying drawings, in which,

Figure' 1 is a side elevationof a per'l equipped with my improved brakel Fig. 2 is a vertical cross section of the said car. 'a is a car body, and b are csr Wheels all of which may be of any conventional construction and connected together manner. i i f5 is a rock shaft extending transversely and journaled in suitable 7' is an arm ltiied'on the rock shaft 5 and pivoted to one end of a connecting rod S, which latter extends longitudinally of the car and has its opposite end portion slightly curved and'suitably connected to an operetin'g lever 9 fulcruined on a pin 10 on the' body a of the car. When the lever is moved outwardly from the end of tl'ie car which also serves as an abutment or-stop for limiting movement of the lever in one direction and into s substantially horizontal position, the point of connection between the connect ing rod and lever, owing to the curvature in the latte-r, will be below the ul'crulned point of the lever and the pin'lO will be received. by a notch 11 in the rod `E3. rihus, .the lever will not' yield under a horizontal pull on the rod 8. v'

' 12-12 are vertically movable bralreshoes.

on opposite sides of the body a and between the wheels 6; The shoes areprovlded with guide rods 13 and 14 which pass loosely through brackets l155-15 on the body e.

residing at l in any preferred Springs 16-16 surround the guide rods'lll and have bearings on the brackets 15, and the tension ci' these springs is adjusted by means of nuts 'lil-1'( screwed onto the guide rods 14. The springs serve to maintain the shoes 12--12 in spaced relation to thev peripheries of the wheels o, but when the operating lever 9 is moved outwardly and downwardly as previously described, the-'brake shoes are brought' into contact with 'the wheels through suitable connections between the rock shaft and brake shoes. nections between the rock shaft and brake shoes may be'=elected in snypreferred man ner such as by arranging cranks. 18-18 on and passing the pins 19MB) .inthe ends of these cranks through the lower end portions 2G-20 of the guide rods projecting helew the .brake shoes, Thus, it will be that when the operationf lever isinoved outwardly and downwardly. scompound leverage will be exerted on the brake shoes 1*'2-12 'This will enable the operator to tighten thebral'es with a minimum of effort and, since the slightest movement. ot' the operating lever outwardly and downwardly will cause the brake'shoes to descend, it is evident that since there will be no lost motion, the brakes may be applied in ay minimum of time.

The device is particularly adapted for dump cars or mining cars, but it will, of course, be understood that it may be' used equally aswell with other types of cars.

What 'l claim as new is:

in a 'ar brake, the combination with a car body and wheels supportingthe same and arranged at opposite sides thereof; of brackets extending laterally from the car body, vertically movable'brake shoes erianged between the wheels on'each side of the car oody and having guide. rods extending through the brackets, springs surrounding certain oi"- the guide rods and serving to yieldingly hold the ,brake shoesin spaced relation tol the peripheriesof the wheels, :i rock shaft extending transversely of the body and connected thereto, connections between the rock shaft and brakel shoes, smn1 ggg am; mmmste tu 4itm-iofs: shaft, a llevara @mme @n one 65nd ci the @armadi aeapte Le@ @buit ich@ emi Wa 0f the car Whenm Vma f; pos-Mm? and a rod connected at @ne an l carini-@fated the levezm' the pxpms@ saai; .v n f :www l
