COMPLETE SPECIFICATION.
An Improved Combined Fire-arm and Walking Stick.
I, ADOLPH LINDNER, of No. 11, Charlotten Strasse, Berlin, Germany, Gentleman,
do hereby declare the nature of my said 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 improvements in firearms of the small arm class; said
improvements consisting of a readily separable small arm, the stock with the lock
mechanism only being attached to the barrel by means of a bayonet catch.
I have represented my small arm in the accompanying drawings as constructed in
the form of a pistol and a walking stick, the handle forming the stock carrying the
lock, whilst the stick proper forms the barrel. The sights can be readily removed
and a screw or other plug be inserted into or over the muzzle of the barrel so that the
arm can be employed as an ordinary walking stick. The lock is cocked in a perfectly
novel manner by means of an arm acting on the cocking slide when the handle or stock
is connected to the barrel or stick, the parts being so arranged that the firing pin is
propelled forwards by the spiral spring, whereas the spiral spring remains inactive
after firing, as the forward end of the same abutts against the rear end of the barrel
and can only be moved forward by its pressure spring when the handle or stock is
freed from the barrel.
Fig. 1, shows the handle containing the lock and connected to a pistol barrel.
Fig. 2, is a view of the barrel as walking stick.

part of the stock.

The cylinder Z, inserted in the handle or stock, is provided with two cavities or
borings; the rear or larger one for the reception of the cocking slide, trigger, springs
and other parts of the lock and the smaller one to receive the needle
which said
needle a is interchangeably connected with the bolthead b by means of a small screw
connection. The hammer or bolt c around which the spring e is coiled, is guided in
the ring d, (Fig. 3), which also serves as resistance to the springe and is fastened
into the cylinder by means of the screw (Fig. 5). The rectangularly bent portion f
of the cocking slide f, passes through the longitudinal slot v of the cylinder z situated
behind the fixed rings d. The other end of this cocking slide projects so far, that on
connecting the handle and shaft, i.e., stock and barrel, the said piece forests against the
butt end of the barrel and can be pushed towards the trigger knob l. The cocking slide
itself remains in its rearward position, even after the discharge, until the barrel is
separated from the stock, whereupon the said cocking slide is liberated and is propelled
forward into the position shown by dotted lines in Fig. 5, by means of the spring
which abutts against the screw plug i. Repeated cocking of the firearm can, therefore,
only be effected by the separating of the handle from the barrel, which separation is
naturally necessary for the loading operation. A spring f2 is situated under the
cocking slide f, the nose f³ of which spring abutts on the rear end of the head b of the
hammer or bolt. Near the end of this spring f there is a lug fª (Figs. 5 & 8),
projecting into the longitudinal slot f¹; said lug₤4 serves also to release the nose,
from the hammer or bolt, when the trigger knob or button is operated to discharge
the arm.
The trigger mechanism consists of a two armed lever op, having its fulcrum on a
suitable pin or peg and carrying the trigger button; the end o of the said lever
being provided with a spring at the bottom to keep it in a raised position (Fig. 6).
The other end P of the lever is provided with the fork o², which is in close contact
with the cylinder When the arm is cocked, the fork o' of the trigger mechanism o
receives the lug 4 of the spring f'; as soon as the trigger knob or button is depressed,
the nose 3 is liberated from the head of the firing piece. Said head band the
needle a attached to the same is then propelled forwards by means of the spring e.and
explodes the cartridge situated in front of it in the barrel. The safety device consists
of a small slide n¹, whose peg or pin n, in like manner as the stem of the button 1,
passes through the slot m of the handle or butt x. Should it be desired to safely lock
the trigger mechanism the safety plate is pushed under the trigger spring o,
thereby preventing the possibility of its being depressed and the gun being fired.
The hammer or bolt is guided by the plates s attached to the cylinder s.
The screws k¹ serve to attach the cylinder z to the handle, whereas the studs or
noses u¹² on the front end of the cylinder, enter into corresponding grooves in the
barrel and effect a tight connection of the cylinder and the handle or stock containing
the lock.
Having particularly described and ascertained the nature of my invention and the
manner in which the same is to be performed, I declare that what I claim is :-
1. In an improved firearm and walking stick combined, the cocking device
consisting of a cocking slide f, which is pushed back when the barrel or shaft is
connected with the stock or handle and having a spring / whose nose f³ hooks on
behind the head of the hammer or bolt and holds the spring e in such manner. that
the projecting end ƒ abutts on the butt end of the barrel, substantially as shown and
described.
2. In an improved firearm and walking stick combined, the discharging device,
consisting of the trigger mechanism op, whose fork o' receives the lug f* of the springf
which spring, on pressing the trigger button l, is released from the head of the
hammer or bolt and allows said hammer or bolt and the attached needle a to be
propelled forward, whereas the cocking device can only be propelled forwards by means
of the spring h, which only comes into operation when the stock is separated from the
barrel, substantially as shown and described.

page_text: 3. In an improved firearm and walking stick combined, the safety device con-
sisting of socuring the trigger mechanism by means of the slide n¹ being moved under
the trigger spring, substantially as shown and described.
4. My improved lock mechanism or any mere modification of the same, substantially
5 as shown and described.
