PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Releasing
Run-away Horses from Vehicles.
I, JOSEPH JACKMAN, of 13, Horton Green, Bradford, in the County of York,
Coachsmith, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvements in the means employed for releasing
run-away horses from the vehicles to which they are attached.
I accomplish my object in the following manner :-
To the ironwork forming what is known as the "Under Carriage," I mount two
levers, and couple the same together with a rod which passes upwards through the
"perch bolt," and through the body of the carriage to within easy reach of the
driver. The ends of the before mentioned lovers, I form with jaws, which grip two
rods connected to the shaft couplings.
When it is desired to release the horse from the carriage, the driver pushes down
the rod extending through the body of the carriage, and thus causes the before
mentioned levers to move on their centres in such a manner as to release their grip
from the rods connected to the shaft couplings, and allow the same to be withdrawn
from their respective positions, and to disengage with the shaft couplings, and thús
release the horse from the vehicle. .
Seeing that the rod which actuates the levers and causes the release of the horses,
passes through the "perch bolt," it is very desirable to relieve the "perch bolt" from
the usual strain to which it has hitherto been subject when in the act of turning the
carriage; this I accomplish by making the bearing plate of the "under carriage"
with an outer rin, and the upper carriage" I prepare to fit within this outer rim,
thus the "perch bolt" is relieved of any strain in the act of turning, as the strain of
the "upper carriage" is thrown upon the entire circle of the rim.
.f
I form on the rim projections at the required position, and a stop on the "upper
carriage" to prevent the vehicles overturning.

Improvements in the Method of and Apparatus for Releasing
Run-away Horses from Vehicles.
I, JOSEPH JACKMAN, of 13 Horton Green, Bradford, in the County of York,
Coach Smith, 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 relates to certain improvements in the means employed for releasing
run-away horses from the vehicles to which they are attached, and consists in mounting
to what is known as the "under carriage" two levers and coupling the same together
with a rod which passes up through the body of the carriage to within easy reach of
the driver.
The ends of the before mentioned levers I form with jaws which grip two rods
connected to the shaft couplings.
When it is desired to release the horse from the carriage the driver operates in a
downward direction the before mentioned rod which causes the levers attached thereto
to move on their centres in such a manner as to release their hold of the rods connected
to the shaft couplings, allowing the same to be withdrawn from their respective

page_text: positions and disengage with the shaft couplings and thus release the horse from the
vehicle.
In order that my invention may be more fully understood 1 will further describe
the same by making reference to the accompanying sheet of drawings in which Fig. 1
represents a plan view of an "under carriage" having my improvement attached
thereto.
Fig. 2. is a similar view shewing the shaft-couplings released.
Fig. 3. is an end view looking in the direction of the arrow.
Fig. 4 is a similar view showing the jaws of the levers disengaged, and
Figs. 5. 6 and 7 are details to a larger scale.
To the framework A. forming what is known as the "under carriage," I mount the
levers B. and C. on the centres B and C coupling the same together on a centre
pin D. passing through rod D' which extends upwards through the "perch bolt" E.
and through the body of the carriage to within easy reach of the driver. The ends
of the before mentioned levers B. and C. are formed with jaws F. which securely grip
the connecting rods G. G. secured to the shaft couplings H. H. by ordinary scarf
joints J. the levers B. and C. being kept in the position as shown by Fig. 3. by the
spring S. hinged on the pin D. at the bottom of rod D¹.
When it is desired to release the horse from the carriage, the driver by pushing
down the rod D' causes the levers B. and C. to move in the direction of the curved
arrows such a distance, as to be clear of the collars K. K. secured to the connecting
rods G. G. and thus allow the latter along with the couplings H. H. to be withdrawn
from their respective positions shewn by Fig. 1 to that of Fig. 2. and thereby to
immediately disengage the shafts, thus releasing the horse from the vehicle.
By the rod D which actuates the levers B. and C. for releasing the horse, passing
through the "perch bolt," it is desirable to relieve the latter from the usual strain to
which it has hitherto been subject on the carriage being turned; this is accomplished
by making the bearing plato M. of the under carriage with an outer rim at M¹ thus
forming a recess into which the "upper carriage" is placed, the circumference of the
same fitting within the outer rim M¹ which by this arrangement receives the strain
hitherto thrown on the "perch bolt " on turning the carriage.
In order to prevent the front wheels turning too far to endanger the safety of the
vehicle, I form within the before mentioned recess of the under carriage plate M.
two pieces N. N. projecting from the outer rim M¹ and on the "
upper carriage"
between the said projecting pieces N. N. is formed a stop by which the front wheels
are only allowed to turn a predetermined distance.
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. The levers B. and C. combined with the rods G. G. and scarfed shaft
couplings H. H. substantially in the manner and for the purpose described.
2. The levers B. and C. combined with the rods G. G. spring S. and operating
rod D substantially in the manner and for the purpose described.
3. The method of attaching the shafts K. by scarfed couplings H. H. to the
rods G. G. and combining therewith the levers B. and C. and operating rod D
all arranged substantially in the manner shown and for the purpose hereinbefore
described.
