Complete Specification Left, 15th Oct., 1898-Accepted, 19th Nov., 1898
I, ERNEST HENRY HILL, of 43, Victoria Road, Broomhall Park, Sheffield, in the
County of York, Brass Founder,. do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to prevent the lid or guiding sleeve of a cycle
inflator, made of celluloid or similar material being driven out of its place by the
working of the piston.
To accomplish this I form a groove or recess beneath the projecting flange of
the lid, or sleeve in such a manner that when the lid or sleeve is screwed into the
outer tube or barrel of the inflator, the edges of the barrel are forced into the
groove, which is so formed as to cause a contraction of the end of the barrel.
Dated this 15th day of July 1898.
I, ERNEST HENRY HILL, of 43, Victoria Road, Broomhall Park, Sheffield, in the
County of York, Brass Founder, 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:-
The object of my invention is to prevent the lid, cap, or ferrule which is secured
upon the end of the barrel of a cycle inflator when made of celluloid or other like
material, becoming loose, or being driven from its position by repeated blows from
the piston.
The annexed drawings illustrate how I accomplish this object.
Fig. 1, is a half sectional elevation of a cap or ferrule made according to my
present invention.
Fig. 2, is a sectional view of the cap when in position, with part of the barrel
and plunger or piston rod.
To accomplish the desired object which is stated above, I form a groove or
annular recess R, beneath and within the projecting flange F, of the cap C, to
receive the end of the celluloid barrel B.
This annular groove R,. is gradually reduced in diameter or contracted towards
its inner end as shown in both figures, consequently when the end of the celluloid
barrel is forced into the said groove by the action of the screw threads S, in con-
necting the two together, it becomes correspondingly contracted upon the cap, as
will be understood.

page_text: This permanent contraction of the end of the barrel B, upon the reduced portion
of the cap C, in addition to the grip of the screw threads, connects the two parts
very firmly together, and enables the cap to resist the repetition of blows arising
from the impact of the piston when the piston rod P, is drawn out to its full extent
during the process of inflation.
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 The improvement in cycle inflators of celluloid or like material, as herein-
before described and set forth.
2-Constructing the metallic cap C, of cycle inflators (made of celluloid or like
material) with an annular groove R contracted in its diameter at its inner end, to
receive and contract the end of the barrel B, and thereby provide a stronger
junction between the two parts, as herein before described and shown.
Dated the 14th day of October 1898.
