IMPROVEMENTS. IN BRAKE BLOCKS FOR CARRIAGE WHEELS
Year: 1885

page_text: JAMES WESTAWAY Coryton, Lewdown N. Devon Commercial Traveller do hereby
declare the nature of my invention for IMPROVEMENTS. IN BRAKE BLOCKS FOR
CARRIAGE WHEELS to be as follows:-
A number of pieces of leather are firmly fastened together and fitted to a dove-
tailed pan so that, when the brake is applied, the ends of the leather are brought
to bear on the wheel and in this way a firm grip is secured.
To support the leathers a piece of wood, iron or other rigid substance is shaped
and fitted to the bottom of the dovetailed pan; and the whole is held firmly
together by means of a square bolt, or the bolt itself may be dovetailed to fit the
pan. Instead of using a bolt, the leathers themselves may be tightly fitted into
the dovetailed pan, in that case, the support at the bottom may be either fixed or
made to slide backwards by means of a thumbscrew for the purpose of adjustment
when the leathers are word, A short screw, passed through the top of the dove-
tailed pan would screw down upon the leathers and hold them tight.
The pieces of leather may be screwed together and held firmly in the dovetailed
pan as described, or they may be fastened to wood or other rigid substances and
the latter fitted into the dovetailed pan.

I do hereby declare the nature of my invention for IMPROVEMENTS IN BRAKE
BLOCKS FOR CARRIAGE WHEELS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
The blocks are composed of a number of pieces of leather (A) firmly fastened
together, and fitted to a dovetailed pan, so that when the Brake is applied the ends
of the leather are brought to bear on the wheel (B) and in this way a firm grip is
secured.
To support the leathers a piece of wood (C) iron, or other rigid substance is
shaped and fitted to the bottom of the dove-tailed pan, and the whole is held
firmly together by means of a square bolt (D) or the bolt may be dove-tailed (E) to
fit the pan.
Instead of using a bolt the leathers (F) may be fitted into the dovetailed pan, in
this case the support at the bottom may be fixed, or made to slide backwards by
means of a thumb screw (G) for use when the leathers are worn. A short screw (H)
passed through the top of the dove-tailed pan will hold the leathers (I) tight, or
they may be fastened to wood or other hard substance, and fitted into the pan.
The pieces of leather are bolted together horizontally, or long pieces of leather (K)
are laced (L) on the bolt, and screwed tightly together, so that the ends may grip
the wheel (M).
Cocoa-nut or other fibre (N) may be placed between the leathers to deaden the
noise, the fibre is passed around the bolt, and the end grain grips the wheel, a few
pieces of leather (0) are fastened together, and placed at each end of the bolt to
prevent expansion, the space between being filled with pieces of leather, fibre or
leather pulp P. which is moulded to take the bolt (D).
