SIMPSON SHEPPARD, Sculptor, 7 St Joseph's Avenue, in the County of the City
of Dublin HERBERT GRAHAM BARNES Sculptor 4 Clare Terrace Harold's Cross in
the County of the City of Dublin and JOHN ALOYSIUS O'CONNELL Sculptor
8 Coal Quay in the City of the County of Cork do hereby declare the nature of
our invention for A MECHANICAL CONTRIVANCE FOR STOPPING AND STARTING
TRAM CARS AND ALL ORDINARY ROAD CONVEYANCES to be as follows:-
A combination of brake and propeller to be worked by coil, push, or pull springs
applicable to Tram Cars Carts Carriages and such like vehicles said combination
being capable of retaining the force expended in stopping such vehicles and utilizing
it for propelling and starting same, thus relieving horses from the strain necessary
for starting such vehicles it consists of two grooved bevel cog wheels on one axle of
car, movable to right or left by lever, said wheels working alternately―(as direc-
tion of car may require) into a similar wheel fixed on shaft (this last may be placed
vertically or horizontally, also a brake wheel on same shaft into which a pin is run
by lever thus preventing slacking or escape of tension on spring and consequently
retaining the power gained by application of brake Thus the driver by action of
lever brings either wheel on axle into contact with vertical or horizontal fixed
wheel, the movement of car working those wheels causes tension or drawing out of
spring, which gradually stops the wheels attached to axle, when stopping the driver
forces the pin into brake wheel attached to fixed shaft, by action of second lever.
This completely stops car and prevents reaction of spring If force to start car is
not required the driver places lever handle so as to move the movable wheels on
axle at equal distance from fixed wheel, neither touching. This sets free the action
of wheels while the power is still retained. When it is required to start Train or
Car by action of brake the driver has simply to move into contact with fixed (hori-
zontal or vertical) wheel--the opposite wheel on axle from that used for the purpose
of braking the vehicle. The pin is then withdrawn from brake wheel on fixed
shaft, the reaction or drawing together of spring works cog wheels the force acting
reversely to force for braking, pushes on the vehicle.
Ouly two lever handles required at front or back of car. Action of lever handles
on front and back being simultaneous & controlled by driver.

the County of the City of Dublin & JOHN ALOYSIUS O'CONNELL, Sculptor, 8 Coal
Quay in the City of the County of Cork. We do hereby declare the nature of our
invention for A MECHANICAL CONTRIVANCE FOR STOPPING & STARTING TRAM CARS
AND ALL ORDINARY ROAD CONVEYANCES to be as follows:-
A combination of brake & propellor to be worked by coil, push or pull springs
applicable to tram cars, carts, carriages & such like vehicles, said combination being
capable of retaining the force expended in stopping such vehicles and utilizing it
for propelling & starting same, thus relieving horses from the strain necessary for
starting such vehicles, it consists of two grooved bevel cog wheels on one axle of car
moveable to right or left by lever, said wheels working alternately (as direction of
car may require) into a similar wheel fixed on shaft this last may be placed vertical or
horizontally also a brake wheel on same shaft into which a pin is run by lover thus
preventing slacking or escape of tension on spring and consequently retaining the
power gained by application of brake. Thus the driver by action of lever brings
either wheel on axle into contact with vertical or horizontal fixed wheel the move-
ment of car working those wheels causes tension or drawing out of spring which
gradually stops the wheels attached to axle when stopping the driver forces the pin
into brake wheel attached to fixed shaft by action of second lever this completely
stops car and prevents reaction of spring-If force to stop car is not required the
driver places lever handle so as to move the moveable wheels on axle at equal
distance from fixed wheels neither touching, this sets free the action of wheels while
the power is still retained when it is required to start tram by action of brake the
driver has simply to move into contact with fixed (horizontal or vertical) wheel the
opposite wheel from that used for the purpose of braking the vehicle, the pin is
then withdrawn from brake wheel on fixed shaft the reaction or drawing together
of spring works cog wheels the force acting reversely to force for braking pushes
on the vehicle only two lever handles required at front & back of car action of
levers on front or back being simultaneous and controlled by driver.
Consists of stationary & revolving perpendicular & cogwheel A on axle H. A bevel
cogwheel A a. also on axle H. Two bevel cogwheels B B. on axle I spring F either
coil, pull or push to which is attached G G which may be wire rope hemp rope or
chain, the other extremity of which is attached to axle H between A and A a round
which it winds. A pin E. which can be inserted between cap of A and is worked by
lever E the handle of which J is worked by driver. See section lever D. which moves
cogwheel B B into cogwheel A a. or places them equidistant from it-worked by
lever handle K. When the tram is in motion the driver places handle of lever K.
so as to bring either wheels B. B. in contact with A a, the rope or chain G. G. is by
this means wound round axle H between A and A a. thus drawing out the spring F
thus braking the car. When stopping the driver moves lever handle J. and inserts
the pin E. in cogwheel A which prevents contraction of spring F. This brakes the

page_text: wheels either way. To go forward, if starting force is not required driver moves
lever handle so as to place cogwheels B. B. equidistant from cogwheel A a. thus
setting free the wheels while power is retained for future use, when the power is
required for starting tram or car, driver moves lever handle K. so as to place in
contact with cogwheel A a.-the opposite cogwheel B. to that put in contact with
it in braking car-the pin E. is then withdrawn by moving lever handle J. the
spring F. contracts so forcing on the car. Should the car have finished its journey
& the start being required to force car in reverse direction to that in which it came,
it is only necessary to keep or put in contact with cogwheel A a. the same cog-
wheel B. used in braking car which by contraction of spring will force car to run
reverse Wav
