COMPLETE SPECIFICATION.
An Improved Device for Preventing Horses Bolting.
I, GEORG FRIEDRICH HEINRICH, CREUTZFELDT,. of 19, Sandstrasse; Lübeck,
in the Empire of Germany, Jeweller, 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 :-
This invention has for its object an improved device for carriages, which comes
into action on the horses attached to the carriage bolting and thereby too sharply.
and suddenly jerking the device, and which whilst acting on the bit also applies a
brake to the carriage.
In the accompanying drawings-.
Figure 1 is a side elevation of the device attached to the front part of the
carriage;:.
Figure. 2 is a front view of the said device;
Figures 3 and 4 are isometrical views of the parts from which the throwing in
and out of gear of the device takes place, and
Figure 5 is a bottom plan of the arrangement for one horse vehicles.
At both sides of the front axle a of the carriage, cog wheels c are mounted on
the inner part of the wheel nave, and engage with two cog wheels f on a higher
shaft e supported at d. A cog wheel g is mounted on the centre of the shaft e,
which shaft like the axle runs transversely across the carriage, and with this cog
wheel g a rack i, adjustably arranged under the pole h of the carriage, engages.
The rack i is prevented from disengaging from the cog wheel g by means of an
annular sheath or holder i', whilst the bar i is attached to the pole. At the front
a spring m acts on this rack, and the latter is provided with a loop n embracing
the pole and provided with an opening. A chain o runs from the ring n to the bit
of the horse.
When the rack i by the pressure of the spring and the action of the cog wheel is
moved entirely into the rearmost position, it encounters a lever pivoted on a bolt k
on the carriage frame, and carrying brake shoes l.
Immediately behind the slide piece n, a link p is arranged on the centre of the
pole (Figures 1 and 4). This link is hinged to the pole and is held in its upright
position by a loop through which run the reins from the coachman's box to the
horse. The hinge for the link p lies in a recess on the top of the pole in such a
way that the lever on being laid down lodges in the pole and the slide piece n can
be pushed backwards as soon as the link p passes through the opening in the ring n.
The centre part of the hinge is attached to the pole and the two revoluble side
pieces are so bevelled off, that, as soon as the link p lies on the pole, the slide
piece n, as already mentioned, may easily be pushed over the hinge. The said
link p ends above in a ring or loop which must be of sufficient size to give room
for the shifting of the reins. The upper part of the whole link p is movable
vertically.
If the arrangement herein before described is to be employed for one horse
carriages, the spring m is mounted on the inside of the rear part of the shafts (see
Figure 5). The hinged rod or link p which in a pair horse carriage lies on the pole
between the two horses, is here arranged on one of the shafts.
Should the horse or horses bolt, the reins rare slackened until the bar p makes &
very acute angle with the pole and can slide through the opening in the part n.
The rack i is then pushed in the direction indicated by the arrow, owing to the

page_text: pressure exerted by the spring m, and the rack engages with the cog wheel g. As
however by the forward movement of the vehicle the cog wheels and c also
engage one another, the rack i is pushed further backwards so that it operates the
lever pivoted on the bolt k and thus presses the brake shoes onto the rim of
the wheel b. The slide piece n simultaneously slips along the pole backwards
over the bar p and pulls up the horse by means of the chain o leading to
the bit.
As appears from the foregoing the bolting of the horse or horses is prevented
by means of the device herein before described, which acts by braking the vehicle
and also by direct action on the horse or horses.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. An improved device for preventing horses bolting, characterised by a rack (i)
arranged under the pole of the vehicle, and adapted on the releasing of a catch-
device (p and n) to engage with a cog wheel (9) set in rotation by the movement
forward of the vehicle, whereby a brake (1) actuated by the rack is applied
substantially as hereinbefore described.
dog
2. In a device such as described for preventing horses bolting, the connecting
of the rack (i) with the bit of the horse or horses, for instance by means of a chain
or cord (o), in such a way that a direct checking of the horse is effected simul-
taneously with the braking of the vehicle, substantially as described.
