page_text: I GEORGE FREDERICK LÜTTICKE of N° 50, Cromwell Road, Hove, in the county
of Sussex, Merchant, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the construction of an improved toy cannon to be
operated by compressed air.
In carrying out my invention I use a suitable air chamber provided with a
spring piston and plunger the latter having a suitable knob or handle for operating
the same; the said chamber is in communication with the rear end of the cannon
by means of a flexible tube; a removeable stopper is fixed in the breech of the
cannon the said stopper having a pin projecting past the opening with which the
said flexible tube communicates. The cannon is mounted on gudgeons in a stand
in the usual manner so that it can be directed or pointed, the herein before described
flexible tube allowing of this being done. A suitable trigger or catch is provided
for securing the plunger when drawn out and allowing of its being easily released
to project a dart or the like.
To project the dart or the like from the cannon the spring piston is drawn out
by means of its knob or handle and is secured in this position by its trigger or
catch the stopper is then removed from the breech and the dart or the like inserted
therein and the stopper replaced; the catch being now released the piston will be
caused by means of its spring to compress the air in the chamber and force it
through the flexible tube into the cannon behind the dart or the like which will
be projected from the cannon with considerable force, the diameter and consequent
capacity of the air chamber being so much larger than that of the cannon.
It will be obvious that the breech need not be made removeable in which case
the dart or the like can be inserted from the muzzle.

page_text: I GEORGE FREDERICK LÜTTICKE, of N° 50 Cromwell Road, Hove, in the county
of Sussex, Merchant, 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 invention relates to the construction of an improved toy cannon to be
operated by compressed air.
In carrying out my invention I use a suitable air chamber provided with a
spring piston and plunger, the latter having a suitable knob or handle for operating
the same; the said chamber is in communication with the rear end of the cannon
by means of a flexible tube; a removeable stopper is placed in the breech of the
cannon the said stopper having a pin projecting past the opening with which the
said flexible tube communicates. The cannon is mounted on gudgeons in a stand
in the usual manner so that it can be directed or pointed, the herein before described
flexible tube allowing of this being done. A suitable trigger or catch is provided
for securing the plunger when drawn out and allowing of its being easily released
to project a dart or the like.
In order to enable my invention to be fully understood I will proceed to
describe the same by reference to the accompanying drawing in which figure 1 is a
longitudinal section and figure 2 an end view of a toy cannon with the plunger in
section constructed according to my invention. Similar letters in both the figures
represent similar parts.
a, represents the air chamber and b, is the piston and c, the plunger with which
the air chamber a, is provided; d, is the spring on the plunger c, for forcing in the
piston b, when released as hereinafter described and e, is the knob or handle for
drawing out the piston; f, is the flexible tube connected to the hollow plugs g
and h, by means of which the chamber a, communicates with the rear end of the
bore of the cannon j; k, is the removeable stopper which is placed in the breech
of the cannon, and, is the pin of the stopper k, which pin projects past the
opening leading to the bore with which the flexible tube f, communicates by
means of the hollow plug h; m, m, are the gudgeons on which the cannon j, is
mounted in its stand n, n, in the usual manner; o, is the trigger or catch for
securing the plunger c, when drawn out as shewn in figure 1, the said trigger or
catch pivotting at p, on the rear end of the chamber a, and being for this purpose
placed in a groove q, in the plunger as shewn so that it can be easily released to
project the dart r, figure 1.
To project the dart r, (or the like) from the cannon the spring piston b, is drawn
out by means of its knob or, handle e, and is secured in this position by its trigger
or catch o,. (as shewn in figure 1) in the manner bereinbefore described; the
stopper k, is then removed from the breech of the cannon j, and the dart r (or
the like) inserted therein and the stopper k, replaced; the catch o, being now
released the piston b, will be caused by means of its spring d, to compress the air
in the chamber a, and force it through the flexible tube f, into the cannon behind

page_text: the dart r, (or the like) which will be projected from the cannon j, with considerable
force, the diameter and consequent capacity of the air chamber a, being so much
larger than that of the cannon j.
It will be obvious that the breech need not be made removeable in which case
the dart or the like can be inserted from the muzzle.
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 combination with a toy cannon of an air chamber in communication
therewith and means for forcing the air compressed in the chamber into the said
cannon substantially as and for the purpose hereinbefore described.
2. The combination with a toy cannon mounted on gudgeons in a stand of an
air chamber communicating with the bore of the cannon by a flexible tube the air
chamber being provided with a spring piston and trigger or catch substantially as
and for the purpose hereinbefore described and represented in the accompanying
drawing.
3. The improved toy cannon herein before described and represented in the
accompanying drawing.
