An Improved Device for Checking Runaway Horses.
I, JOHN MCKENZIE, Engineer, of Abbotsford, Thetis Road, Cowes, Isle of Wight,
do hereby declare the nature of this invention to be as follows:-
_
This invention relates to a device to be employed for stopping runaway horses,
and its object is to provide an arrangement which can be easily applied and which
will bring the horse to a standstill.
In carrying out my invention I propose to fit to the inside of the wheel hub
a grooved pulley or wheel over which a chain or rope passes. This connection
also passes over a second grooved pulley carried by a spindle to which it is fitted
by means of a feather. This wheel is free to move to one side so as to engage with
or disengage from the spindle, and a forked lever is employed to bring it into
or out of position, this lever being worked by the hand or foot of the driver. On
the spindle a worm or screw is formed, and on this a sleeve or clutch is placed,
screwthreaded internally so as to fit the worm. One end of this clutch is formed
with a tooth adapted to engage with the end of a pulley, formed in a corresponding
manner and carried loosely on the spindle. The ends of the clutch or pulley are
of screw form the thread being right handed and that of the worm left handed.
The spindle is provided with a stop preventing the clutch or sleeve being drawn
too far back, and a second stop or pin is placed between the clutch or pulley,
preventing the former being forced against the latter. The clutch is formed with
longitudinal grooves and above it a pin is fitted in a small cylinder or socket within
which a spring is placed. This spring causes the pin to project into the groove
for the purpose hereinafter described.
On the loose pulley first described being caused to engage with the spindle by
the lever, the spindle will be turned and will screw the clutch forward until it
engages with the pulley. The latter is then turned with the clutch winding up a
strap or connection passing to the reins until the vehicle is stopped. On the horse
backing the arrangement will at once be disconnected, the spring pin above.
described preventing the clutch from turning and so allowing it to be screwed back
releasing the clutch pulley and letting the horse have his head.

I, JOHN MCKENZIE, Engineer, of Abbotsford, Thetis Road, Cowes, Isle of Wight,
do hereby declare the nature of this invention and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the follow-
ing statement:
This invention relates to a device to be employed for stopping runaway horses,
and its object is to provide an arrangement which can be easily applied and which
will bring the horse to a standstill.
In carrying out my invention a small shaft is fitted in bearings supported on
the axle tree of the vehicle and toothed wheels are employed to transmit motion
from the wheel hub to this second shaft. This second shaft is formed in two
portions and the coupling which connects the two portions can be moved by
means of a forked lever to one side or the other so as to connect or disconnect the
two portions, this forked lever being worked by the hand or foot of the driver. On
the spindle, a worm or screw thread is formed, and on this a sleeve or clutch is
placed, screw threaded internally so as to fit the worm. One end of this clutch is
formed with a tooth adapted to engage with the end of a pulley or reel formed in
a corresponding manner and carried loosely on the spindle.
The spindle is provided with a stop preventing the pulley wheel being drawn too
far back. The clutch is formed with ratchet shaped teeth and a pin is fitted in
a small cylindrical hole or socket within which a spring is placed. This spring
causes the pin to project against the teeth for the purpose hereinafter described.
On the loose pulley first described being caused to engage with the spindle by
the lever, the spindle will be turned and will screw the clutch forward until it
engages with the pulley. The latter is then turned with the clutch winding up
a strap or connection passing to the reins until the vehicle is stopped. On the
horse backing the arrangement will at once be disconnected, the spring pin above
described preventing the clutch from turning and so allowing it to be screwed back
releasing the clutch pulley, and letting the horse have his head.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings,, in which Fig. 1 is a view showing the device
applied to a vehicle, Fig. 2 is an elevation of the device, Fig. 3 is an elevation at
right angles to Fig. 2 and Fig. 4 is a detail view.
Upon the axle tree A of the vehicle two brackets B, B₁ are fitted within which
the shaft C, C is supported. The shaft C, C¹ is in gear by means. of the toothed
wheels a al with the wheel axle. The two portions. C, C of this second shaft are
connected by means of the coupling box C having feather ways c which will in
one position gear with the feather keys c¹. The coupling box C slides on the
feather keys so that it will turn with the shaft C and can also move lengthwise
thereof. To effect this lengthwise movement a grooved portion is fitted to the
coupling box C2 with which a forked lever D engages. The shaft. C¹ is thus, thrown
in or out of gear.
The rod D is actuated by cranks and levers in any well known manner and can
be operated either by hand or foot as desired.
The spindle C is mounted in the double bracket B₁ and kept from lengthwise
movement by means of the pin e and other portions of the mechanism as will
readily be seen.
Between the arms of the. bearing, bracket and loosely mounted on the spindle
is a pulley or reel F on which winds a cord strap or other connection G connected
to the reins H and which will when wound on the said reel cause the reins to
tighten and so stop the horse.
To throw this reel F into gear with the said spindle C, the projection or nose f
is provided engaging with a similar projection; on a clutch J which is fitted on a
worm or screw threaded portion of the spindle, and which will when the spindle
is revolved cause the clutch to engage with and revolve the reel.
In order to prevent the clutch revolving with the spindle before being properly
engaged with the reel, the pin K is provided fitting into a recess formed in a pro-
jection 61 on one arm of the bearing bracket which is caused to. press against the
clutch by the spring k placed at the bottom of the recess.
The clutch is formed with the ratchet shaped teeth j¹ which depress the pin

page_text: when the spindle is revolved thereby preventing the latter being revolved in the
wrong direction.
In the arrangement illustrated, in addition to the teeth j¹ formed on the clutch J
a second set of teeth are also provided with which the portion K¹ of the tooth K
engages. According to the position of the clutch J on the worm so either the
teeth will engage with the tooth K or the teeth will engage
with the tooth K and whether the device is in or out of action
the spindle C is prevented from being revolved in the wrong direction. In Fig. 4
only one of these sets of teeth is illustrated but the other acts similarly but for the.
opposite direction.
On the horse backing the clutch is immediately drawn out of gear with the reel
and the connection and reins are released but on the horse advancing again the
reins are tightened and the horse stopped.
The reel may be provided with ball bearings if desired to reduce the friction
against the bracket.
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) An improved device for checking runaway horses, consisting of a spindle
supported adjacent to the vehicle wheel and geared with the vehicle axle, detach-
able connections between said spindle and vehicle axle, a clutch on the spindle
carried by a worm or screw and a loose reel on the spindle engaging with the
clutch, and connections to the reins, substantially as described and for the purposes
specified.
(2) In an improved device for checking runaway horses, the combination with
a spindle and detachable connections between the spindle and vehicle wheel of a
worm or screw on the spindle, a clutch on the worm, a loose reel on the spindle
adapted to engage with the clutch and connections from the reel to the reins sub-
stantially as described and for the purposes specified.
(3) In an improved device for checking runaway horses, the combination with
a spindle supported adjacent to the vehicle wheel and geared with the vehicle axle
and detachable connections between said spindle and vehicle axle, of a worm or
screw on the spindle, a clutch on the worm, a spring pin engaging with the said
clutch, a loose reel on the spindle adapted to engage with the clutch, a stop for the
clutch and connections from the reel to the reins substantially as described and for
the purposes specified.
(4) In an improved device for checking runaway horses, the combination of the
double spindle C, C¹ mounted in brackets B, B¹ on the axle tree A of the vehicle,
the toothed wheels a, a' connecting the spindle C and the wheel axle, the coupling
box C3 connecting the two portions of the spindle C, C by means of feather ways c,
and feathers c¹ and grooved portion with which forked lever D engages
clutch J upon worm and reel F engaging with the clutch J and connections from
the reel to the reins substantially as described and shown in the accompanying
drawings and for the purposes specified.
