PROVISIONAL SPECIFICATION.
Improved Means for Securing the Shafts of Carriages.
I PESTONJEE BYRAMJEE PRESS of Frere Road, Fort, Bombay, India, Coach
Builder do hereby declare the nature of this invention to be as follows:-
My said invention relates to improvements in the method of securing the shafts
or poles of carriages and other vehicles.
Hitherto the shafts of carriages have frequently been connected by a bolt passing
through suitable jaws and through the posterior end of the shaft so as to form a
hinge on which the shaft may turn.
The head of the said bolt is so formed as to serve as a point of attachment for
the leather trace and the bolt is held in position by a nut.
In the event of the horse falling or of its leg getting over the shaft it is often
extremely difficult to take off the nut for the purpose of withdrawing the bolt in
order to detach the shaft and release the horse.
According to my said invention I dispense altogether with the nut and provide a
curved spring one end of which is hinged to the head end of the bolt at one side of
the shaft.
The spring is carried underneath the shaft and the other or free end of the spring
is provided with an aperture through which the point of the bolt passes.
The free end of the spring thus bears against the side of the shaft opposite to
the head of the bolt and the spring forms a clip which holds the bolt securely in its
place.
In order to remove the bolt it is only necessary to pull the free end of the spring
outwards and downwards from the bolt.
The latter can then be readily taken out and the shaft may be at once detached
from the carriage.

COMPLETE SPECIFICATION.
Improved Means for Securing the Shafts of Carriages.
I PESTONJEE BYRAMJEE PRESS of Frere Road, Fort, Bombay, India, Coach
Builder, 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 :-
My said invention relates to improvements in the method of securing the shafts
or poles of carriages and other vehicles.
Hitherto the shafts of carriages have frequently been connected to the carriage
by a bolt passing through suitable jaws and through the posterior end of the shaft
so as to form a hinge on which the shaft may turn. The head of the said bolt is
so formed as to serve as a point of attachment for the leather trace and the bolt is
held in position by a nut.
In the event of the horse falling or of its leg getting over the shaft it is often
extremely difficult to take off the nut for the purpose of withdrawing the bolt in
order to detach the shaft and release the horse.
In order that my invention may be more fully understood I will describe the
same with reference to the accompanying drawings.

page_text: Figure I of the said drawings illustrates the ordinary method of securing the
shaft B. A A are the jaws or futchels. C is the hinge.bolt herein before referred
to and which is secured by the nut d.
Figures II to IV illustrate my said invention.
C
According to my said invention I dispense altogether with the nut d and provide
a curved springs one end of which is hinged to the head end of the bolt c at one
side of the shaft by a pin p. The spring is carried underneath the shaft and the
other end o of the springs is provided with an aperture s¹ through which the
point of the bolt passes. The end o of the springs thus bears against the side
of the jaw opposite to the head of the bolt and the spring forms a clip which holds
the bolt securely in its place.
In order to remove the bolt it is only necessary to pull the free end of the
spring outwards and downwards from the bolt as indicated in dotted lines in
Figure II which is an end elevation of Figure II. The bolt can then be readily
taken out and the shaft may be at once detached from the carriage.
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―
I. As a means for attaching the shafts of carriages and the like vehicles the
combination of a bolt and a curved spring substantially as hereinbefore described
and shown.
II. In an articulated connecting joint for the shafts of carriages the use of a
curved spring for retaining the hinge bolt in position substantially as herein before
set forth and shown.
Dated this 5th day of April 1892.
