Improvements in Brakes for Vehicles.
1, CHARLES CARRIE. of East Castle Street, Broughty Ferry, in the County of
Forfar, Scotland, Cart, Lorry, Van and Waggon Bailler, de hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in brakes for vehicles, the object being
to brake" vehicles in an improved manner an I by means of impraved apparatus.
The type of brake usually applied to those vehicles which are drawn by horses
along ordinary roads is one in which the shoes" are appliel on one side of each
wheel. Sometimes, when say a lorry is heavily loaded, such type of brake cannot
be properly or sufficiently applied, the result is, that if such Irry be coming down
a steep incline, it is apt to overpower the horse and seriously injure or even kill it.
In order to overcome this defect I have designed a brake whose shoes are applied
on opposite sides of each wheel, thus effectually retarding their rotation.
In carrying out my invention I employ the ordinary hand wheel with screw and
nut to actuate the coupling rod, such hand wheel being placed in any convenient
position. The coupling rod is attached to a lever whose fulcrum is at its centre,
such fulcrum being supported by the axle block. The shoes are hung by ro ls
from the frame of the vehicle, one on each side of each wheel. The rear pair of
shoes are coupled to the upper extremity of the aforesaid lever, the front pair
being similarly coupled to the lower extremity of the lever, or conversely.
In another modification I couple the two suspension rods in such a way that
both shoes may be drawn together or separated, that is to say one suspension rod
may have its fulcrum between the point of application of the power and the
shoe, while the other rod may have the power applied between tho she and the
fulcrum.

1, CHARLES CARRIE, of East Castle Street, Broughty Ferry, in the County of
Forfar, Scotland, Cart, Lorry, Van and Waggon 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:-
This invention relates to improvements in brakes for vehicles, the object being
to "brake" vehicles in an improved manner and by means of improved
apparatus.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto

page_text: appended an explanatory sheet of drawings in which the same reference numerals
are used to indicate corresponding parts in all the figures where shown.
Figure 1. is a sectional elevation at A. A. (Figure 2).
Figure 2. is an under plan with the wheels removed for clearness of illustration.
Figure 3. is a section at B. B. (Figure 4) of a heavy lorry.
Figure 1. is a part under plan of same, the wheels being removed for the reason
previously stated.
The type of brake usually applied to those vehicles which are drawn by horses
along ordinary roads is one in which the "shoes" are applied on one side of
cach wheel. Sometimes, when say a lorry is heavily loaded, such type of brake
cannot be properly or sufficiently applied, the result being that if such lorry be
coming down a steep incline, it is apt to overpower the horse and seriously injure
or even kill it. In order to overcome this defect I have designed a brake whose
shoes are applied on opposite sides of each wheel, thus effectually retarding their
rotation.
In carrying out my invention I employ the ordinary hand wheel 10. with
screw 11. and nut 12. to actuate the coupling rod 13, such hand wheel being placed
in any convenient position. The coupling rod 13. is attached to a lever or
levers 14. whose fulcrum 15. is at or near their centre, such fulcrum being
supported by the axle block 16. or by the frame 19. of the vehicle. The shoes 17.
are hung by rods 18. from the frame 19. of the vehicle, one on each side of the
wheel. The rear pair of shoes are coupled by the rod or rods 20. to the upper
extremity of the aforesaid lever 14, the front pair being similarly coupled by the
rods 21. to the lower extremity of the lever, or conversely, as in Figures 3. and 4.
In another modification I couple the two suspension rods 18. in such a way that
both shoes may be drawn together or separated, that is to say one suspension rod
may have its fulcrum between the point of application of the power and the shoe,
while the other rad may have the power applied between the shoe and the fulcrum
as illustrated by Figures 1. and 2.
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 I
claim is :-
(1) In brakes for vehicles, the combination and arrangement of parts, sub-
stantially as herein described and illustrated with reference to Figures 1. und 2.
of the annexed drawings.
(2) In brakes for vehicles, the combination and arrangement of parts, sub-
stantially as herein described aud illustrated with reference to Figures 3. and 4.
of the annexed drawings.
