I, ROBERT PRICE, of No. 85, Hagley Road, Birmingham, in the County of
Warwick, Ironfounder, do hereby declare the nature of this invention to be as
follows:-
My invention consists of the improvements in or additions hereinafter
described to brakes for wheel carriages of the kind described, represented and
claimed in the Specification of Letters Patent granted to me No. 19,594 of 1890.
By the said patented invention the brake plate in its normal or out of action
position is eccentric to the wheel and on operating the brake lever the said brake
plate is brought gradually into action.
In order that the present invention may be the more readily understood L
remark that with the patented invention referred to when the vehicle is heavily
loaded the brake is sometimes so lowered or depressed with respect to the wheel
that the eccentricity of the brake plate is destroyed and its action impaired the
action of the brake commencing at the upper end of the brake plate instead of at
the lower end and failing to come fully into action.
The present invention has for its object to remedy the defect referred to and
this I effect by the following construction and arrangement of parts. The brake
plate is jointed to a forked arm on the end of the brake lever as in the patented
invention referred to but the set screw for determining the position of the brake
plate with respect to the wheel when the brake is out of action is dispensed with.
To the forked arm carrying the brake plate a short slotted lug is fixed by means
of a set screw passing through the slot in the said lug the said lug terminating
in hooks with which the ends of coiled springs are engaged. The other ends of
the said springs are connected respectively to the brake plate near its ends. By
the construction and arrangement of parts described the brake plate is permitted
to turn in either direction on the pin or axis of the forked arm and hence which
ever end of the brake comes first into action on the application of the brake the
brake plate turns on its axis until it bears fully on the tyre of the wheel.

I, ROBERT PRICE, of No. 85, Hagley Road, Birmingham, in the County of
Warwick, Ironfounder, do hereby declare the nature of my invention and in what
Price 8d1

page_text: manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
My invention consists of the improvements in or additions hereinafter
described to brakes for wheel carriages of the kind described represented and
claimed in the Specification of Letters Patent granted to me No. 19,594 of 1896.
By the said patented invention the brake plate in its normal or out of action
position is eccentric to the wheel and on operating the brake lover the said brake
plate is brought gradually into action.
In order that the present invention may be the more readily understood I
remark that with the patented invention referred to when the vehicle is heavily
loaded the brake is sometimes so lowered or depressed with respect to the wheel
that the eccentricity of the brake plate is destroyed and its action impaired, the
action of the brake commencing at the upper end of the brake plate instead of at
the lower end and failing to come fully into action.
The present invention has for its object to remedy the defect referred to and
this I effect by the following construction and arrangement of parts. The brake
plate is jointed to a forked arm on the end of the brake lever as in the patented
invention referred to but the set screw for determining the position of the brake
plate with respect to the wheel when the brake is out of action is dispensed with.
To the forked arm carrying the brake plate a short slotted lug is fixed by means
of a set screw passing through the slot in the said lug the said lug terminating
in hooks with which the ends of coiled springs are engaged. The other ends of
the said springs are connected respectively to the brake plate near its ends. By
the construction and arrangement of parts described the brake plate is permitted
to turn in either direction on the pin or axis of the forked arm should one or
other end of the brake come first into action on the application of the brake the
brake plate turns on its axis until it bears fully on the tyre of the wheel.
Figure 1 of the accompanying drawings represents in side elevation, a brake
constructed according to my present invention showing the position of the brake
with respect to a carriage wheel in the normal or out of action position of the said
brake.
Figure 2 represents the said brake in vertical section in action and Figure 3 is
a hack elevation of the same.
Figure 4 is a cross section (drawn to a larger scale than Figures 1, 2 and 3)
taken through the forked end of the brake lever and through the joint of the
brake plate.
Figures 5, 6, 7 and 8 are nearly similar views to Figures 1, 2, 3 and 4 of a
modified brake hereinafter described.
The same letters of reference indicate the same parts in the several figures of
the drawings.
I will first describe the arrangement Figures 1, 2, 3 and 4
is the brake plate jointed by means of the pin to the forked end of the
brake levere which is jointed at to the brake axis of the carriage as usual. To
the forked end 2 of the brake lever the slotted plate e is fixed by the screw
pin f the ends of the slotted plate terminating in hooks e², e². To the hooks e²e
springs g, are connected the other ends of which springs are hooked to
hooks a', a at or near the ends of the brake plate a.
b
By the construction and arrangement or combination of parts described the
brake plate a is permitted to turn to a limited extent in either direction on its
joint pin consequently should through over-loading of the vehicle or otherwise,
the body of the vehicle be so lowered or changed with respect to the wheels that
on the application of the brake one or other of the ends only of the brake plate
come in contact with the wheel the said end of the brake plate will yield until
the brake plate bears wholly on the wheel. On the removal of the brake from
the wheel, the springs g, g ensure the return of the brake plate a to its normal
position.
In the modification Figures 5, 6, 7 and 8, the forked end of the brake lever

page_text: is dispensed with, the brake plate being pivoted to the end c¹ of the brake lever c
directly. The part of the brake lever between the side lugs a², a² of the brake
plate à (see Figures 7 and 8) has a flat on its outer side against which the slotted
plate e is fixed by the screw pin f which in this case engages in a screwed hole
in the axial end c¹ of the brake lever c. In other respects the modified brake
Figures 5, 6, 7 and 8 is the same as that first described.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as
my invention :--
;-
First The construction and arrangement or combination of parts herein-
before described and illustrated in Figures 1, 2, 3 and 4 of the accompanying
drawings constituting an improved brake for wheel carriages, the said construc-
tion and arrangement of parts consisting essentially of a brake plate or brake
proper pivotted to and capable of turning in either direction on the forked ter-
mination of the brake lever the brake plate being brought into or maintained in
its normal position when not in use by two coiled springs respectively engaging
with the brake plate at or near its two ends and a plate on the back of the
forked end of the brake lever substantially as and for the purpose herein before
described and illustrated.
Secondly: The modification
herein before described and illustrated in
Figures 5, 6, 7 and 8 of the accompanying drawings in which modification the
brake plate or brake proper is pivotted directly on the end of the brake lever the
slotted plate for the inner ends of the restraining springs to engage with being
fixed directly to the end of the brake lever constituting the axis of the brake
plate substantially as hereinbefore described and. illustrated.
