PROVISIONAL SPECIFICATION.
Improvements in Terminals for Shafts of Vehicles.
I FRANK SALES PERKINS of 220 Penton Place, Walworth in the County of
Surrey, Coach Builder do hereby declare the nature of this invention to be as
follows:-
This invention relates to terminals for shafts of vehicles usually called caps or
points. These caps or points as usually employed form ornamental terminals for
the shaft and avoid splintering the wood at that point which frequently comes in
contact with the ground.
In cases of horses falling the shafts of vehicles are frequently broken by coming
in contact with the uneven ground before the vehicles come to rest and such
accidents happen especially with shafts which are curved downwards towards the
points. Moreover shaft points are a source of danger in cases of collision with
other vehicles or horses.
The object of my invention is to provide means by which the shaft point may run
freely upon any surface with which it may come in contact and to minimise the
shock in case of collision with the shaft point.
For this purpose I make the shaft point or terminal with a socket at one end to
receive the shaft and bifurcated at the forward end to receive between. its two
prongs a rotatable buffer preferably of vulcanized india rubber. Such a terminal
causes the extremity of the shaft to travel freely over uneven ground when driven
in contact therewith by the vehicle to which it is attached. In cases of collision
with the shaft terminal the shaft will be driven downwards or upwards according
to the contour of the surface with which it comes in contact and so the shock of
the collision will be minimised and in case of a direct blow upon a flat surface the
yielding quantity of the rubber provides a buffer at the point of contact.
I make an ornamental opening at each side of the socket end of the terminal in
order to provide for opening or closing the socket sufficiently to admit shafts
varying in size within certain limits.

Improvements in Terminals for Shafts of Vehicles.
I FRANK SALES PERKINS of 220 Penton Place, Walworth in the County of
Surrey, 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 :-
This invention relates to terminals for shafts of vehicles usually called caps or

These caps or points as usually employed form ornamental terminals for shafts

In cases of horses falling the shafts of vehicles are frequently broken by coming.
in contact with the uneven ground before the vehicle comes to a standstill and
such accidents happen especially with shafts which are curved downwardly towards
the points: Moreover shaft points are a source of danger in cases of collision with
other vehicles or horses.

run freely upon any surface with which it may come in contact and to minimise
the shock in case of collision with the shaft point.
For this purpose I make the shaft, point of terminal as shown by the accom-
panying drawings in which
Figure 1 is a side view of a shaft point fitted to a shaft.

rotatable buffer preferably of vulcanized india rubber.
rotatable buffer is fitted with a bush C and rotates upon the screw D.
Such a terminal causes the extremity of the shaft to travel freely over uneven
ground when driven in contact therewith by the vehicle to which it is attached.
In cases of collision with the shaft-terminal A the shaft will be driven downwards.
or upwards according to the contour of the surface with which it comes in contact
and so the shock of the collision will be minimised and in case. of a direct blow upon
a flat surface the yielding quality of the india rubber provides a buffer at the point
of contact.
I make the ornamental opening Fat each side of the socket-end of the terminal
in order to provide for opening or closing the socket sufficiently to admit shafts
varying in size within certain limits.

J
A shaft-point or terminal provided with a rotatable wheel made preferably of
material which will yield to a blow and so perform the function-of-a-buffer sub-
stantially as and for the purpose described.
