CHARLES LANE, JOHN BURR LANE and ERNEST LANE, all of 45 New
Church Street Bermondsey, London S.E. Surrey, Engineers and Lead Novelty
Manufacturers do hereby declare the nature of this invention to be as follows:-
DESCRIPTION OF INVENTION.
Our invention consists of a projection (made of metal or any other substance)
fixed on an air gun, and shaped in such a way that by placing the hollowed back of a
bullet against it with the hand, at the same time pressing and twisting, it expands
the bullet so as to make it perfectly air tight when placed in the barrel, thereby
giving greater force.
The advantage gained can be easily imagined as the bores of air gun barrels vary
to such an extent that it is impossible to get a bullet made to fit without our
invention.

COMPLETE SPECIFICATION.
An Improvement in Air Guns to Make the Bullets or Slugs Shoot
with Greater Force.
We, CHARLES LANE, JOHN BURR LANE, and ERNEST LANE, of 45* New
Church Street, Bermondsey, London, Manufacturers, 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 our invention is to provide a perfectly air tight fitting bullet for
air guns.
The bores of air gun barrels vary to such an extent that it is impossible to
supply bullets to fit accurately the barrels of the guns unless some means are
adopted for expanding the bullets so as to make them to perfectly fit the gun
barrel.
·
In order to do this we provide a projection or stud made of metal, or any other
suitable material which may be screwed into the stock of the gun or in any
other convenient position. The end of this stud is cone-shaped or preferably
chamfered down to a point, with five or more flat sides. By placing the hollowed
back of a bullet or slug against the conical end of the stud, and at the same time
pressing and twisting the bullet, the hollowed part is rimered out and caused to
expand so as to make it perfectly air tight when placed in the barrel, thereby
giving it greater projectile force.
In order that our invention may be better understood, we will proceed to describe
the same by reference to the accompanying drawings in which
Fig. 1, represents an enlarged side view of the projection or stud, with the bullet
shown in section placed against the point of the stud,
Fig. 2, an end elevation of the same, and
Fig. 3. a perspective view of the stud.

page_text: In these views A is the screw for fixing the stud into the stock of the gun, B is
the flange or shoulder, and C the conical end of the stud, D the bullet with its end
expanded after twisting on the conical face of the stud, E being a section of the
said bullet before it has been expanded.
Fig. 4 shews the stud screwed into its position on the stock of the air gun.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The provision of a projection or stud having a conical end, the said stud being
screwed into the stock or other suitable part of an air gun for the purpose of
expanding the bullets by placing their hollow ends against the stud and rimering
the same so as to make them fit perfectly air tight in the barrel substantially as
described, set forth, and illustrated in the accompanying drawings.
