page_text: I, WILLIAM PEARSON, of 120 Camberwell Grove, Camberwell, in the County of
Surrey, Wheelwright, do hereby declare the nature of my said invention to be as
follows:-
The object of my invention is to manufacture an improved form of brake and
brake block, suitable to wagons, vans and other vehicles.
In carrying out my invention I form the brake block with a moveable shoe
fitted thereto. The working face of the shoe is grooved or fluted, transversely.
The brake block is supported by an adjustable bearing, fitted with an india
rubber, or other elastic washer, whereby the shoe adjusts itself to the wheel, and
its whole surface thereby becomes effective, when in contact with the tire of the
wheel.
The brake is applied to the wheel by any of the known means, and is varied
according to the character of the vehicle; thus, in vans and omnibuses, it may be
actuated by the driver's foot, applied through the ordinary levers; in the case of
railway rolling stock the brake would be applied as usual; and in tramcar traffic,
with the usual screw-gear and levers.
The shoe can be removed, when worn, and a new one fitted, without disturbing
any of the gear in connection with the brake. -
I prefer to form the shoe of malleable iron.

I, WILLIAM PEARSON, of 120 Camberwell Grove, Camberwell, in the County of
Surrey Wheelwright, do hereby declare the nature of my said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my invention is to manufacture an improved form of brake and
brake block, suitable to wagons, vans and other vehicles.
In carrying out my invention I form the brake block with a moveable shoe
fitted thereto The working face of the shoe is grooved or fluted, transversley.
The brake block is supported by an adjustable bearing, fitted with an india
rubber, or other elastic washer, whereby the shoe adjusts itself to the wheel, and
its whole surface thereby becomes effective, when in contact with the tyer of the
wheel.
The brake is applied to the wheel by any of the known means and is varied
according to the character of the vehicle; thus, in vans and omnibuses, it may be
actuated by the drivers foot, applied through the ordinary levers; in the case of
railway rolling stock the brake would be applied as usual; and in tramcar traffic,
with the usual screw gear and levers.
The shoe can be removed, when worn, and a new one fitted without disturbing
any of the gear in connection with the brake.
I prefer to form the shoe of malleable iron.
It is obvious that the form and direction of the grooves may be varied, and
arranged diagonally and otherwise.
And in order that my said invention may be particularly described and ascer
tained, reference hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a side view of my improved brake, the brake block and shoe being
formed in one piece. Fig. 2 is a side view of the brake block and moveable shoe.
Fig. 3 is a face view of Fig. 2, and Fig. 4 is a plan view of a lever, with the brake
block and shoe attached.
a is the brake block, b is the shoe, c c are grooves or serrations, formed trans-
versely to the face, d is the bolt on which the block is capable of pivotting and
adjusting itself to the wheel, e is a nut to secure the block. Between this nut and
the block, a metallic washer f and rubber or other elastic washer 9 are placed.
is the brake lever, which moves upon a pivot at i. The rubber washer g affords
sufficient elasticity to enable the block to adjust itself to the periphery.
The form of brake block shewn in Fig. 1 may be used for very light work, but
for heavy work the form of brake block and shoe shewn in Figa. 2. 3 and 4 are
preferred the brake block a is formed with a tongue k, which enters a groove in
the shoe, as shewn in Fig. 2. are two bolts, passing through the shoe, and
secured to the brake block by nuts m m. The shoe is thus securely fastened to the
block; and, when worn down the shoe can be readily removed, and a new one
fixed without disturbing any other part of the apparatus.]

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The manufacture and use of brake blocks having grooves, serrations, or corru-
gated surfaces, c c substantially as and for the purposes hereinbefore described and
shewn in Fig. 1 of the drawings.
2. The method of mounting brake blocks by means of adjustable bearings,
substantially as and for the purposes hereinbefore described and shewn on the
drawings.
3. The manufacture and use of the moveable brake block shoes, constructed,
arranged and operating substantially as hereinbefore described and shewn in
Figs. 2. 3 and 4 of the drawings.
4. The general construction, combination and arrangement of the several and
respective parts, together forming my improvements in brakes, substantially as
hereinbefore described and shewn on the drawings.'
