GENERAL DESCRIPTION.
A bossed tube carrying a disc and a pinion, is so placed upon the axle of a
vehicle actuated by any power, that it may receive rotation, through gearing,
from a wheel of the vehicle:
Tubes are screwed into the bosses, upon which weights, or pallets, are able to
rise and fall against the action of springs, and act centrifugally, proportionate
to the speed: so that they meet an angle ring, that is carried by a tube on the
axle of the vehicle, and give it rotation. The angle ring has a hook for horse
traction, and a joint for inechanical powers, by which when the vehicle advances
too rapidly, rods, links and levers, draw up the power, and by one end of a radial
slot in the angle ring, and other rods, puts the brakes against the wheels.
Should a horse back the brakes are put on by the other end of the radial
slot similarly; but the rods or straps that draw up the horse, are left at rest on
a stop, by the hook, the horse not being affected.
The arms of the angle ring carry other rings upon which a lever worked by
hand or foot is carried which by slotted links is connected to the brake rods :
so that the brakes may be put on alone, by hand.
The tube on the axle of the vehicle carrying the angle ring has a disc, and
outside it, one or more screw bolts with two heads, that embrace the disc upon
the first named tube, and the bolts are so connected by gearing to a handle, that
when rotated by it, the two discs are clamped and work synchronously: thus
when it is desired the vehicle shall not move; should the power start, the angle
ring is rotated either backwards or forwards through the discs, and the several
effects above explained obtain.
When the reins are drawn back, the horses heads is affected as usual: and
in the case of a steam engine a throttle valve in the steam pipe, or its substitute
for other mechanical powers is more or less closed.

page_text: carries upon its nave, or spokes, the cog wheel C that gives motion to a pinion D
whose spindle DA drives the cog wheel E: the wheel E drives the pinion F which
gives motion to the tube G, that is carried by the axle B upon balls or otherwise :
the tube G has two or more bosses GB, four shown: each boss G B carries
screwed into it, a tube H and each tube H carries a pallet J, having wedge
shaped peripheries, sectionally, concentric with the axle B and able to slide up and
down upon it: the tubes H hold down a spring HA, the other ends of which are
adjustable, by the nut H B that is screwed upon the pallet J, so that the tension of
the spring HA regulates the centrifugal action of the pallets J.
An angle ring K is supported concentrically to the axle B, by arins KA, that
are united by rings K B one of which is produced and carried upon the axle B.
The tube G carries a disc or face plate L that rotates with it, and the arms KA
at M are formed as a second disc two screw bolts M A carry double heads MD
and pinions MB: and a toothed wheel MC is able to rotate the screws MA by
means of the bevelled pinions ME and MF, when the handle M G is rotated,
and so force the two discs L and M against, and lock one another, and work
synchronously.
A looped lever N is carried by the rings K B and KBA which are formed upon
the arms KA the upper part of the lever N at NA is hinged at NB, has a
handle and carries the end of a rod NC: the rod NC has projections N D by
which it may be actuated with the foot the rod NC also carries the end of slotted
links NDA, the other ends of which are connected by a bolt NE, that passes
through a slot KC formed on the periphery of the ring K.
The bolt NE also connects with the diagonal rods or straps M K, the other ends
of which are attached to the cross rod N F: the rod NF passes through radial
slots N G in the support NJ, and carries one end of each brake block N H, the
other ends of which are also carried and hinge upon the support NJ.
The angle ring K carries a hook KD for horse, and a joint KD takes the place
of the hook KD for mechanical traction, which are connected to the lever or
levers KZ by the bolts KE and K F, links KG, and diagonal rods, straps, or
cords KH the levers K Z actuate the reins, or auxiliary reins K J.
The working is as follows:-
:-
When it is desired the power shall stand, the handle M G is rotated, this by the
bevelled pinions M E and MF, wheel MC, and pinion M B, draws up the screw
bolts MA, and their heads M 1) clamp the discs L and M together, thus
Should the power start forward, the wheel A A gives motion to the ring K by
the pinions C, D, E and F, and the bolt K E with the rods KH, lever KZ and
reins KJ are drawn back: the power is drawn up: and the brakes are put on
simultaneously by the rotation of the ring K causing the end of the slot KC to
meet the bolt NE, which draws the rods MK and NF back, and the brakes
against the wheels.
Should the power back, the ring K is reversed, and the hook K D in the case of
horse power leaves the bolt KE and the links KG resting against the stop KL,
being drawn back by the spring K M, and the brakes are put on as before, but by
the other end of the slot KC acting against the bolt NE, which also draws
down the links NDA and lever N to their dotted positions: but for mechanical
traction the power is drawn up as in going forward, by the joint KD carrying
back the rods in the opposite direction.
When the power is desired to advance, the speed is regulated by the wheel A A
rotating the pallets J by the pinions C, D, E and F, and when their centrifugal
force exceeds that of the springs II A, they fly outward, take against the ring K
and rotate it, which by the hook, or hinge, K D draws down the bolt K E,
rods K H, lever K Z and reins K J against the spring K M, and checks the
power, more or less proportionate to its speed. Simultaneously the end of the
slot KC meets the bolt N E and puts on the brake, by drawing back the rods M K
and N F.
When descending inclines the brakes are put on by the foot acting against the

page_text: projections ND, which thrust over the lever N, and draws
back the rous IVL
and NF by the links NDA and this may also be done by the handle NA:
but should the speed unduly increase, the above actions of reins, and brakes again
obtain.
When the brakes are drawn against the wheels A A, their thrust is taken at
the top, by the bolts N L, upon which they hinge and also by the bolt N F, by
its sliding blocks taking against the radial slots N G.
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. Attaching to an axle of a vehicle driven by any power such gearing and
so fixed, that one of its wheels fixed upon a wheel of the vehicle, shall be able to
rotate a tube or hollow spindle, carried on the axle of the vehicle by balls or
otherwise, at any desired speed: for so fixing upon, or forming said tube with two
or more bosses, that a tube may be screwed into each boss, at right angles to it,
and secure one end of a spring, placed within or outside it: so that the spring
passes up the tube, and is attached, by means of an adjusting screwed nut, to a
peripherally wedge sectioned pallet, able to slide up and down, outside the said
tube, against the power of the spring, when acting centrifugally for fixing an
angle ring concentrically with the pallets and carried upon arms, connected at one
end by a ring, and the other by a tube able to rotate upon the axle of the
vehicle forming upon the angle ring a hook for horse, and a hinge for mechanical
traction, that by links and diagonal rods or cords, works a lever, or levers,
centering upon the shafts of the vehicle, and affects the horses head, when the
angle ring is rotated by the pallets acting upon it, by their centrifugal energy
obtained through the vehicle wheels, when it is advancing: but should a horse go
backward, the reverse action of the angle ring allows its hook, to leave the links,
and rods, working the reins, resting against a stop but the hinge for other powers,
draws back the rods in either direction, similarly, and checks or stops them, through
a throttle valve, or its substitute for forming upon the angle ring, a radial slot in
which the bolt, connecting with the brakes of the vehicle wheels passes, so that
when the angle ring is rotated and checks the power, the end of the slot meets
the bolt and puts on the brakes and that when the vehicle goes backward,
and the angle ring is reversed, the brakes are put on by the other end of the slot
meeting the bolt: for connecting the bolt that passes through the angle ring slot
with a hand and foot lever, by a pair of slotted links, so that the brakes may be
put on by foot or hand while the power is free to act, substantially as described.
2nd. For fixing upon the said tube or hollow spindle carrying the pallets a disc,
that rotates with it: and fixing a second disc, upon the tube that supports the
angle ring upon the vehicle axle, and forming a boss on one or more of the arms
attaching the disc to the angle ring, and screwing a bolt into it or them, which has
two heads placed above, one on each side of the first named disc: the bolts also carry
a pinion, geared into another, carried by the vehicle axle, and which has a bevelled
pinion attached, that through its fellow connects with a handle within reach of the
driver so that when turned by him, the handle by means of the pinions rotates
the screw bolts, and screws up the two discs against one another: so that should the
vehicle move in either direction the power is acted upon as claimed above substan-
tially as described.
3rd. For fixing rings upon the arms of the angle ring, and supporting thereon
a looped hand lever that carries a pair of links, through the slots of which, the
bolt that connects with the brakes, and passes through the radial slot in the angle
ring, also passes; the hand lever also carries a rod with projections so as to be
available for the foot of the driver: thus when the lever is thrust over by the
foot or hand, the brakes alone are put on substantially as described.
4th. For so arranging the brakes, in connection with the foregoing apparatus,
that one end of each is a hinged fixture, and the other ends are connected by a

page_text: transverse rod, which passes through radial slots, and the brakes are thrust
against the wheels by the diagonal rods that are connected to the transverse rod
close to the brakes, so that when acting against the wheels, the reaction is taken at
both ends of the brakes substantially as described.
