TO ALL WIHOM 1T MAIY CONCERN:

Be -it known thst. I, GEORGE B. S'rnvENs, of Pluckeiniginthe' county of Somerset, andI State or New Jersey, have invented eertain 'new'ond useful Improvements in Sled-Brakes, of which the followingis a, full,-

cleer, and exact 'deseription, reference: beiughadto the' acconipanying' drawings, which make part of this speci-.

fication, and in' 'which-- I p I "Figure l represents a. plan or. top view ofa sled'hsvjing-my improvenientsattached.

1 First, in a nevel method of constructing and attaching the hearings in which'the brake turns,,as herei'n after set forth. v

Second, in a novel rnethod of-combining the hearings in which the brak-rod'tur'ns with plates on'the" under side of the side-pieces of the sled, as hereinafter set forth.

In the accompanying drawings, ILA represent two p'ieesof iron fitting over'the cross-brace B, one endof each piece being bent down behind the brace, to which they are secured by screws from,above',,.or from the rezir, and their other ends bent down and curved to form sockets, O, in which the rod Dturns. 'lo the underside of the side-piecesE E, and to the upper front sides of the uprights F, are secured metal plates, G, against which the bar 1) hears when. the brake is in operation. These plates prevent the rod from leaving its, open bearings, andprotect' the woodwork of the sled from injury. y

To oneend of the bar D is welded asgrape'r. or drag-bar, E. If preferred, this scraper may he formed by bending the rod D, or it may be keyed on to the rod. To the other end of the her D is'w'elded or keyed a lever,

When the operator slackens the rope, the weight of the'lev'er-I i et nrns 1t to'a horizontal posi-' ti'on. "Theserapers are thus automatically lifted from the ground, zind this is caused by thetlengthoftlie lever being greater thauthatof the scraper. The upper end'ofthe lever maybe made thicker and heavier thanthe scrapers, if preferred. An arm may also beottache'd'sbove the scraper H, it deerne'd necessary to ensure perfeet operation.

I I I side-pieces, as described.

Having thus :fully described the construction and operation of my impz oved brake, what I claim therein as my invention, and desire to secure by Letters Patent,ris

1. The cdmbination with the turning rod D of the open bearings constructed and applied. to the cross-brace B, as and for the purpose set forth.

2. The arrangement of the epen bearings, the flanged turning brake-rod, and the plates G beneaththe' In testimony whereof; I have hereunto subscribed. my name; j
