Improvements in the Distribution and Controlling the Distribution
of Power on Vehicles.
I ROBERT COOKE SAYER of 11 Clyde Road, Redland Bristol, Civil Engineer
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 :-
The object of this invention is to distribute power on cars or trains of them so
that electric power, by magnets, regulates pneumatic or other power to actuate
their brakes, and that their action may not depend on the weight of the cars and
be equally effective when traversing small and large rails, their main wheels are
toothed, made in two parts to run on light toothed rails and open telescopically,
laterally, when introduced to larger rails by a short tapering length of rails, or
closed together when returned: so that when drivers, guards, and passengers, when
desired, actuate switches in the electric circuit, the brakes are put on or taken off,
and the motors converted into brakes. A tube conveying the pneumatic power
carries screw nuts and when it is rotated they are traversed and give motion to
levers to put on the power of the motors and actuate jaws to fix the half wheels.
This is attained as set out in the following detail description and four drawings.

Power is supplied to the tube D through a friction joint 1 Figs. 1 to 4, pipe 2
insulating joint 3 and axle joint 4 of the wheel H it passes to the tap K by
pipes 94, 5 and 6 to a regulating cylinder L, Fig. 5. by pipe 7 to the wheel brake
cylinder G and from motor cars Fig. 10. to trailers Fig. 11 by the joints B, Qand
couplings F of Patent No. 10539 A.D. 1896 and by joints R supply the
reservoirs T, taps K and cylinders G round which the car J rotates.

cranks 10 centering on G at 11: the slot 12 of the lever 13 by its pin 14 actuates
the radials 24 of Patent No. 21523 A.D. 1895 or arm 15. Fig. 12 to pick up or not
the electric circuit the lever 13 centers at 16 is actuated by the trunnions 17 of the
nut 18 meeting the vertical part of the cam slot 19 when it is traversed on threads
of the tube D or fixed at rest as the trunnions 17 pass on in the diagonal part of
the slots 19 when horizontal: the lever 13 moves its fellows 13 by the rods 20:
a lever 21 similarly supported formed and worked by the tube D actuates by the
pin 22 the lever 23 centering at 24 to put on the motors not shown: and other
similar levers actuate scissor jaws 25 and 26. Fig. 15, to centre on journals 27
at 28 and thrust one up and the other down by the slot 12 actuating the pin 29
rod 30 hinging on 26 and the links 31 hinging on both at 32 on the lever 33 that

at 38 and release the parts 39 and 40 of the wheel H. that with flangeless wheels
Figs. 9 and 10 support the car, the tyre of the part 39 is divided at 41 to admit the
teeth 42 of the part 40 to the rail teeth 43. 39 have teeth 48 and each spokes 44
and 45 that support and are keyed to their axles 46, journals 47 and 27 spaced
apart to allow, by the jaws 25 and 26, Fig. 15, for the difference in width of the
the small rails A Fig. 12 and large ones Fig. 13.
The taps K. Fig. 8. carry a lever 49 Fig. 5 on its spindle 51 which is actuated.
by the armature levers 50 of the electro magnet N against the spring 52, it has
passages 53 that exhaust one side of the piston 54 of the cylinder L by the tapered
aperture 55 regulated in size by its screw 56 while it supplies power to the other
side to thrust out the rod 57 and by the lever 58 and links 59 actuate the valve V
to close the exhaust pipe 60 in which is fixed the non-return valve W connecting
by pipe 61 with the motor supply 62 which supplies by pipe 63 the passage 64
Figs. 6 and 7 of the valve V, that before the exhaust pipe 60 is closed supplies by
pipes 65 and 66 the two ends of the motor cylinder through non-return valves not
shown.
When the tap K sends power to project the piston 54 it also goes by pipe 7.
Figs. 1 to 5. to the cylinder G.
The working is as follows.
A current of electricity goes by wire 68 to the drivers switch 67. Fig. 10.

magnet N of the second bogic truck to the joint 4 and by the arın 15 and
contact 80 completes its circuit to a station as per Patent No. 15192 A.D. 1894,
when the trailing car Fig. 11, or any number are coupled it passes by the
coupling F to its fellow F and by the wire 81 from 77 and F contact 82 guards

one bogie truck to N of the other, conductors 89 and 90 the two couplings F
through the motor car, Fig. 10. joint 4 or arm 15. Fig. 12. as before.
The tube D runs the whole length of the train, gives motion to the nuts 18.
Figs. 1 to 3. whose trunnions 17, traversing the cam slot 19 of the levers 13 and 21,
thrust them over by the vertical parts of the slots 19 in the case of lever 13 to
lower or raise the radial conductors of cars as per Patent No. 21523 A.D. 1895 or
the arins 15 to pick up the current: the lever 21 by its slot 19 pin 22 and lever 23
puts on or off the power to the motors: when the diagonal parts of the slots 19
become horizontal continued travel of the nuts 18 to operate the jaws 2) and 26
holds the levers 13 and 21 in position.
Before the wheels H leave a light rail Fig. 12. for a heavy one, Fig. 13, the
shaft D is rotated, actuates the levers 25 and 26, and admits their passing over a
short length of rail whose centre part 91 tapers as well as the teeth 43. Their
width is regulated to that of the teeth 43. Fig. 12. and its groove 92, to return to a
light rail Fig. 12. the taper rail has outer bevelled teeth 93 dotted to thrust the
parts 39 and 40 of the wheel H together and when in place the jaws 25 and 26 are
returned by reversing the tube D to keep them so.
When the electric circuit is severed by a switch the levers 50 of the magnets N
are drawn away by the spring 52. reverses the tap K by its lever 49 from position
Fig. 8. opens the passage 95 to supply power through pipe 94 to the back of
piston 54 by pipe 5. Fig. 5. while passages 53 and 55 exhaust its front and the
rod 57 closes the valve V: before V is closed the passage 64, Figs. 6 and 7 send
power by pipes 65. 66 and 63 and non-return valves to each end of the motor
cylinders: excessive pressure is prevented by the motor piston thrusting it back
through the non-return valve W to its reservoir: vacuum is prevented by the
supplies of pipes 65 and 66. When the tap K sends power to the pipe 5 it also
goes by pipe 7 to the cylinders G. Figs. 1 to 4. raises its piston 8 puts on the
levers by the link 9 and cranks 10 against the sides of the part 39 of the
wheel H. Figs. 12 and 13. the width of O spans its projections 96. thus O act

page_text: against each other through 39: the cylinders G and L are also exhausted by the
tap K. on trailing cars Fig. 11. they actuate the brakes O only, which are taken
off by the springs 97. Fig. 4. and the motors resume their normal use.
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
1st. Actuating taps K to keep power from cylinders G and L by completing an
electric circuit through car couplings F as per Patent No. 10539 A.D. 1896 the
coils of electro maguets N and switches 67 and 83 under the control of drivers and
guards, returning it to the drivers motor car Fig. 10: severing the circuit by
actuating a switch enabling springs 52 to withdraw their levers 50 from the
magnets N convert the car motors into brakes by closing their exhaust pipe 60
with a valve V formed with a passage 64 to supply power before it is closed to
both ends of the motor cylinders, or their equivalent, through non-return valves,.
actuating the valve V with power acting in a cylinder L by its piston 54 rod 57
and lever 58 regulated by the tap K and its exhaust port 55, and thereby the
levers that act against the sides of central or side toothed double or single
wheels H and one another by actuating the piston 8 of cylinder G to put them
on by links 9 and cranks 10 substantially as described and shown on the drawings.
2nd. Giving motion to screwed nuts 18 on a tube D, conveying power by the
couplings F Figs. 10 and 11 of Patent No. 10539 A.D. 1896 throughout a train of
cars, and by their trunnions 17 acting against vertical parts of cam slots 19 of
levers 13 and 21 to thrust them over until diagonal parts of the slots 19 become
horizontal and allow the trunnions 17 to pass on and hold the levers in position
while the trunnions of other nuts similarly act against the vertical parts of the cam
slots 19 of other levers and give them motion substantially as described and shown
on the drawings.
3rd. Toothed wheels H for supporting the cars formed in two parts 39 and 40-
acting telescopically, the parts being separated and drawn together by an
introductory tapering rail and fixed by scissor jaws 25 and 26 to traverse small.
or large rails substantially as described and shown on the drawings.
Dated this 1st day of June 1896.
