BRAKE-LEATHER HOLDER FOR ROAD-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 769,836, dated September 13, 1904.

Application filed September 8, 1903. Serial No. 172,334. (No model.)

To all whom, it nuty concern:

Be it known that I, JOHN JOSEPH RUSSELL,

assistant postmaster, a subject of the King of Great Britain, residing at Milton, in the State of New South Wales and Commonwealth of Australia, have invented a new and useful Improved Brake-Leather Holder for Road-Vehicles, of which the following is a specification.

This invention relates to an improved brakeleather holder for road-vehicles; and it has been specially devised in order to dispense with the ordinary unsatisfactory brake-block holder, brake block and leather or like filling or lining, and to replace these by an easily-adjustable contrivance for presenting an easilyprepared leather packing or filling to the wheel from the end of the brake arm or lever.

Thisimproved brake-leather holder for roadvehicles consists of a skeleton metal frame adjustably attached to the brake arm or lever and having a metal jamb-plate adapted to form a backing for the leather packing and to press and hold said leather in place, whether in a continuous run or composed of short pieces; but in order that this invention may be clearly understood reference will now be made to the drawing.

The accompanying drawing illustrates in perspective as operating on a wheel an improved brake-block holder for abuggy or the like constructed according to this invention.

In a back plate 1 are slots 2, through which pass bolts 3 for attaching thereto the bracket 4 and allowing for adjustment of such bracket sidewardly that the brake-face may be fixed centrally of the peripheral face of the wheel. This bracket intakes on the diminished end 5 of brake-arm O and is kept in place by nut 6. It is somewhat loose, but has its range of movement governed by pintle 7, so that the brake-face cannot present itself otherwise than properly to the face of the wheel and will adjust itself to the curvature thereof. Instead of the connection shown the bracket 4 may be hinge-jointed to the brake-arm or be attached by any other mechanical device allowing of the before'mentioned functions. From this back plate 1 project side plates or cheeks 8, each having therein a Slot 9, the forward periphery of which is serrated. Traveling backwardly and forwardly of this slot 9 is the brake-plate 10, curved to the circle of the wheel and having rabbets 11 at top and bottom,forming guides on the ends of slots 9 for itself. Preferably on the top of said plate 10 is a backwardly-bent flange 12 as a protection only against mud or the like falling between said plate 10 and the back plate 1. Screws 14 pass through the back-plate 1 and preferably through bosses 13 thereon and have jam-nuts, as 15, if desired. These screws 14: abut against the back of curved brake-plate 10 and are adapted to force said plate forwardly and hold it against pressure backward.

The plate 10, extending as it does flush on each side with the outer face of the cheeks 8,

is adapted when forced forwardly to grip and hold upon anything between its inner face edges (which also may be serrated, if desired) and the serrated periphery of the slot 9. This gripping characteristic'is utilized to hold the brake-leather (meaning the leather filling, packing, or lining usually nailed to brakeblocks) in proper position. These leathers 16 in strips or in pieces (it does not matter, so

long as they are wide enough to stretch from side to side of the holder) are packed between the serrated periphery of the slot 9 and the curved brake-plate 10 and said plate forced forwardly by means of set-screws 141, thus gripping and holding the leather in place.

In use the brake-arm O is actuated in any ordinary manner to apply the brake, which in tion with a back plate 1 having set-screws 14: therethrough of a curved brake plate 10 guided by ends of a slot 9 in cheeks 8 and a serrated edge on the periphery of said slot on which said brake-plate 10 may jam or grip material substantially as herein described and explained and as illustrated in the drawing.

2. In a brake-leather holder, the combination of a rabbeted brake-leather, a rabbeted brake-block, and a frame in which said leather and block slide, said rabbets fitting on the corners of said frame.

3. In a brake-leather holder, the combination of a brake-leather, a brake-block, a frame for said leather and block provided with a serrated portion upon which the leather rests, and set-screws for forcing the block against the leather to cause it to be gripped by the teeth of the serrated portion of the frame.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

JOHN JOSEPH RUSSELL. Witnesses:

M. GENTRY, S. BAILEY.
