Improved Means for Stopping_or Controlling Runaway or Restive
Horses.
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 is to prevent vehicles starting unexpectedly, and to keep control of
them when on the move, see drawing, where
Fig. 1 gives a general view
Fig. 2 part elevation and part section
Figs. 3, 4 and 5 cross sections
of the arrangement applicable to vehicles, of which one pair of wheels work
laterally, for turning; and where there is not room upon the main axle.
A represents a vehicle, having its front wheels A A, and shafts A C arranged to
work round a centre A B; one of the wheels A D has a flange or cog-wheel A E
attached, that by a pitch chain or strap A F drives a pinion B D which gives
motion to, and is carried by the spindle B: B works on ball or other bearings BA
Fig. 3 that are carried by the supports BC.
The spindle B carries keyed to, or forming part of it, the boss B E into which are
screwed any number, four illustrated at Figs. 1 to 7, and three by Figs 8 and 9, of
tubes BF: each tube B F carries a peripherally coned pallet B G, Fig. 4, able
to slide upon it, but normally rests upon the boss B E and is prevented from
turning laterally by the sides B K that are carried by the supports B C.
The pallets B G are pierced, screwed, and carry nuts B H.
BH carry one
end of a spring B J, the other end being secured by and at the base of the
tube B F.
The sides B K carry, by the wheels or balls B L, the cone recessed ring B M,
concentrically with the pallets B G. B M has attached a horizontal bolt BQ.
One of the supports BC is produced and carries the lever B N, which centres
at B N A, and carries one end of the rod or chain or strap, or partly each B P.
has a segment B N B, attached concentrically to its centre B NA, and a
spring BN C, or a second lever, similar to B N, having a similar segment
to B N B, and also a bolt B N D fixed rigidly to B N, and passing through the
spring B N C.
Between the said two segments B N B and B N C, but normally clear of
both, a disc B O is passed which is fixed upon, and rotates with, the spindle B:
and the bolt BQ of the ring B M is placed close to the lever B N.
The rod, chain or strap BP is passed between the two wheels C, it then branches
into two, and is attached to the stirrup lever D at D B: the lever D centres
at D A, and carries auxiliary, or the main reins E, through the loop DC: so that
the rod or chain B P radiates from C and centre A B, with the wheels A A and
shafts A C.
The working is as follows:-
By the wheel A E, Fig. 1, and pinion B D the spindle B, Fig. 3, is rotated,
and with it the pallets B G: when the speed exceeds that regulated by the
nut B H, Fig. 4, which puts greater or less tension on the spring B J, the
centrifugal force causes the pallets B G to overcome the springs B J, and B G
enters the recess of, and meets the ring B M, and causes it to rotate upon the
wheels or balls L, carrying the bolt BQ with it, which thrusts the lever B N
over to its dotted position, and thus draws back the rod, chain or strap B P,
lever D, and reins E, and checks the speed of the horse or other power: when the

page_text: speed falls, the pallets B G are withdrawn by springs B J, and a spring or
springs F, withdraw the levers D, and B N which also returns the bolt BQ and
ring B M, ready to repeat the motion.
When it is desired to leave, and prevent a vehicle from starting the second lever, at
the side of B N, centering upon BN A, or the spring arm B N°C of the lever B N,
as the case may be, and the lever B N are made to approach one another, by the
driver screwing up the nut of the bolt B N D, thus the two segments BN B
and BNC clip the disc B O, and when the spindle B is rotated as before, by the
vehicle moving, the disc BO rotates within the segments BN B and B NC, and
causes them and the lever B N, to draw back the rod or chain B P and reins E as
before, and stop the vehicle.
When there is not room to adjust the nut B H, Fig. 4, of the pallets B G by
removal of a side B K, ring B M and other parts, three pallets B G, Figs. 8 and 9,
carried by the face plate B R are used: B R is slotted and lugs on B G enter the
slots, and carry bolts BS whose heads keep them in place thus, room is obtained
for outside springs B J, between the pallets B G, that are adjusted by the
bolts BH: the pallets B G work the same as above described.
.
When there is room for the arrangement upon the main axle of the vehicle, it is
fixed there as shown at
Fig. 6 in a general view and
Fig. 7 in a detail cross section.
The wheel A D of the vehicle carries a wheel A E, that gives notion to the
pinion B D, that through the wheel B DA and pinion B D B gives motion to its
attached bossed spindle B E which rotates, through balls B E A, upon the
axle B E B of the vehicle: the spindle B E, as before, carries the tubes and
pallets B F and B G, and disc B O, and other parts are similarly lettered to
the above explained, and the working is the same.
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
one
1st. Attaching to the main axle of a vehicle, such gearing and so fixed,
that one of the wheels fixed upon one of the wheels of the vehicle, shall be
able to actuate a spindle, carried on the main axle by friction balls or other-
wise, at any desired speed: for so fixing upon, or forming said spindle with two
or more bosses, that a tube may be screwed into each boss and secure
end of a spring, placed within it, so that the spring passes up the tube, and is
attached by means of an adjusting screwed nut, to a peripherally coned pallet, able
to slide up and down outside the said tube: for so fixing side plates clear of, but
able to prevent said pallets from turning laterally, and also support friction wheels
or balls, which carry concentrically with said spindle and pallets, an intradosal cone
recessed ring for so fixing upon the said recessed ring a bolt at right angles to its
vertical plane, that when the pallets receive a rotary motion, their centrifugal force
shall cause them to travel outward upon said tubes, against the tension of said
springs, and their coned peripheries to enter the recess of the concentric ring, and
cause it to rotate upon said wheels or balls, and bring the right-angle bolt against
a lever and give it motion: so that a rod or chain or strap or partly each, attached
to the lever, and conducted between friction wheels, that confine it to above the
centre pin, upon which the front, turning wheels of the vehicle, and the shafts,
centre or turn and on to a stirrup lever, to which auxiliary or the main reins are
attached so that when the lever is moved by said pin or bolt the stirrup lever
and reins are drawn back, and stop the horse or other power substantially as
described.
2nd. For so attaching to said bossed spindle, a disc placed between two
segments one being fixed upon said lever which is actuated by said pin or bolt,
and a second forming part of a second lever similar to the last, and working upon
the same centre: or the second is a spring segment and attached to the lever, as

page_text: the case may be for fixing a bolt to the lever carrying the first segment and
passing it through the second segment lever, or segment spring, so that upon
screwing up the nut of the bolt, the two segments are drawn together and pinch
upon said disc, so that when the disc rotates by the unexpected starting of the
vehicle, it causes the segments, and the lever or levers, to be passed to their second
position, and draw back the reins, and stop the animal or other power, which so
remain until the said nut and spring be released by the driver, then a spring returns
the rein and other levers substantially as described.
3rd. For three or more pallets arranged to give space between them for springs
and their adjusting bolts, and supporting them upon a disc, capable of rotation, so
that the pallets receive its motion through lugs which enter radial slots in the disc
being secured by bolts the springs and their bolts are also carried by the disc: so
that when the speed exceeds that for which the springs are adjusted, the lugs
traverse the slots, and the pallets fly outwards centrifugally substantially as
described.
4th. When there is not room upon the main axle of the vehicle for the arrange-
ment claimed, the geared wheel fixed upon the vehicle wheel gives motion, through
teeth, a belt, or pitch chain, to a pinion attached to an independent shaft, and the
pinion gives the other parts motion as above substantially as described.
