PROVISIONAL SPECIFICATION.
Improvements in Brake Blocks or Skids for Carriages and other
Vehicles.
I, FREDERICK RICHARD CHURCH JOYCE, of Farnborough, in the County of
Hampshire Coach Builder do hereby declare the nature of this invention to be as
follows:
My invention relates to improvements in brake blocks for vehicles generally, and
has for its objects the better fixing and adjusting of the wearing surface of said
blocks.
In carrying my invention into effect I may employ brake blocks of India rubber,
metal, wood or other suitable material, forming a dove-tail or other kind of slot in
the back thereof, extending from the bottom nearly to the top. Suitable headed
bolts, or studs and nuts made to fit said slots are fitted therein and pass through the
brake shoes, holding the block tightly thereto by means of nuts, pins or keys, and
thus rendering said blocks or skids easy in adjustment or removal.

COMPLETE SPECIFICATION.
Improvements in Brake Blooks or Skids for Carriages and other
Vehicles.
I FREDERICK RICHARD CHURCH JOYCE of Park View, Farnborough, in tho
County of Hampshire Coach Builder do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to improvements in brake blocks or skids for use upon
vehicles generally, the novelty and object of which is the simplicity of its attachment
to the brake iron or arm upon the vehicle, which permits of the block being worn
almost entirely away before needing renewal.
In order that my invention may be more easily understood I have appended the
accompanying sheet of drawings in which Fig. 1 is a general view of the block
according to my invention with one bolt only shewn in position within the slot or
groove. Fig. 2 is a cross section of the same, Fig. 3 is a detached view of one of the
bolts adapted for use upon a block with such a groove as shown in Figs. 1 and 2.
Fig. 4 is also a cross section of a block similar to Fig. 2 the difference lying in
the formation of the groove or slot, and Fig. 5 is a bolt suitable for use with
Fig. 4.
In carrying out my invention I construct a block A of india rubber, vulcanite, or
vulcanite and india rubber, wood, metal or other suitable material, preferably rect
angular in cross section, and form therein a slot or groove B for nearly the entire
length thereof, into which I slide bolts, nuts, or studs Figs. 3 and 5 in the manner
shewn at Fig. 1, the heads of which are shaped to fit the groove or slot into which
they are caused to slide or I may as an alternative method for the nuts in such a
manner as to correspond to said slots or grooves, the said bolts or nuts are pushed
along the groove until their position coincides with holes in the brake iron or arm
made to receive said bolt and through which they pass, suitable nuts C made to fit
the bolts are then screwed thereon until the block is drawn close up and firmly
attached to the brake iron or arm upon the brake lever of the cart carriage or other
vehicle upon which the brake block is to be fixed, or I may fit the bolts into the
D

page_text: brako iron or arm and slide the block thereon. Fig. 1 illustrates one of said bolts in
position within the groove of the block, but I may use in practice any number of
bolts according to the length of the block, or the number of holes in the brake iron or
arm that is to receive said bolts.
For the purpose of illustration I have chosen to show in the accompanying
drawings sections of blocks with a dovetail and T shaped groove respectively Figs. 2
and 4 and bolts or studs with heads shaped to fit therein Figs. 3 and 5, but I may
form the said groove of any suitable, shape or design in cross section, and provide
bolts nuts or studs to fit therein without departing from the principle of my invention,
and I wish it understood that I do not use or claim the intervention of any substance
between my improved brake block and the brake iron of arin of the vehicle to which
it may, be attached, but fix said block directly upon the brake iron or arm in the
manner shewn and described, thus providing means for removal and renewal in a few
minutes, the same bolts, nuts, or studs serving for the fixing of a new block when
necessary.
Having now particularly described and ascertained the nature of my said, inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
.
First The combination of a brake block for vehicles, of suitable material, with
a groove or slot formed therein, with bolts, nuts or studs corresponding thereto
substantially as and for the purposes. herein described with reference to tho
drawings.
Second The method of and means for attaching the brake blocks of vehicles to
the irons or arms therefor, substantially as described.
