WALTER THOMAS TOMS Albion House Newbury Dentist do hereby declare the
nature of this invention to be as follows:-
:-
An invention for depressing the pole-spring whilst withdrawing the pole from the
pole-irons of a Fire Engine or any carriage using a pole fitted with a pole spring; and
automatically readjusting itself, when the pole is placed in its position
And thereby preventing the risk of injury to the hand of the person removing the
pole.
To be made entirely of metal.
To be fixed on centre of the "Splinter bar" by clipping or hanging on, and
secured firmly in its position by 3 screws in front and 2 at back.
It consists of a metal clip with a lever handle, worked on a pivot bolt and supplied
with a small wheel at the bottom of the lever handle, to prevent wear to the pole
spring and to reduce friction.
By pushing back the handle the small wheel presses down the pole-spring flush, so
as to allow the pole to be "unshipped” or withdrawn from the pole-irons.

pole-irons of a Fire-engine or any carriage using a pole fitted with a pole-spring
and automatically readjusting itself when the pole is placed in its position and
thereby preventing the risk of injury to the hand of the person removing the pole.
To be composed of the following parts, vizt.
The "Metal Clip," marked F on drawings, made to be fixed on the centre of the
"Splinter bar" by clipping, or hanging on, and secured in its position by three
screws in front and two at back, marked b. b. see figures 1, and 2., sheet 1.
The "Lever Handle" D., fitted with a small wheel A to prevent wear to the pole-
spring and to reduce friction, and having a "stop-pin " H, in front for regulating the
lever action. The "Lever handle" to be made of metal.
A "pivot bolt" e, upon which the lever-handle works with "lock-pins” d. d. to
each nut-head for security.
A small metal wheel A, at the end of the lever-handle D, also working on a pivot-
bolt with lock pins to each nut-head.
By pushing back the lever-handle D, the small wheel A presses down the pole-

page_text: 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,
First. A simple and easy method of depressing the pole-spring whilst withdrawing
the pole from the pole-irons of a fire-engine or any carriage using a pole fitted with a
pole spring.
Second. Prevention of injury to the hand whilst withdrawing the pole from the
pole-irons.
Third. A great saving of time whilst withdrawing the pole from the pole-irons.
Fourth. That the fitting is inexpensive and easily adjusted by any ordinary
mechanic in a few minutes.
