A New or Improved Air Toy Gun.
We, WILLIAM HENRY CALKINS, Salesman, CHARLES AUGUST LINDBERG,
Machinist, WILLIAM MATHEWS BUTTS, and AUSTIN KENT WHEELER, Wholesale
Merchants, all residents of the City of Grand Rapids, in the County of Kent and
the State of Michigan, United States of America, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:—
This invention relates to a toy air gun and is represented in the accompanying
drawing where:
Figure 1 is a longitudinal section of the gun showing the relative position of
its several parts; Figure 2 is an enlarged sectional view of a portion of the barrel
and stock showing the point of contact between the sear and the piston; Figure 3
is a sectional elevation of the breech-piece; and Figure 4 is an end view of the
same.
Similar letters refer to similar parts throughout the several views.
The barrel A of the gun is constructed of a large tube a having a small tube a¹
supported within by plugs d, said smaller tube being designed as the channel or
bore of the barrel through which the shot is forced; and the air chamber a to
which the tube a is securely attached. Back of the air chamber is a cap A¹
which is formed to slip over the end of the tube a and bears against the end of
the stock B. This cap is provided with a slot b¹ for the passage of the rod E,
and has a sight 6 struck from its upper surface.
The piston is constructed with a metallic head c to which is secured a leather,
or other suitable packing e, fitted to confine the air and force it through the air
chamber and the tube a; a second head c¹¹, and the two heads are connected by
the bars cl
The front surface of the head c" is made slightly concave or inclined backwards
so that the hook g on the end of the sear G will engage it as a slightly inclined
hook, and thus avert the danger of its becoming accidentally disconnected there-
from and prematurely discharging the gun. In Figure 2 we have shown the lower
portion of the head c¹¹ in section, to illustrate this feature of our invention, see g¹.
The sear is composed of the continuous lever G G¹ pivoted to the stock B, as
at gl, and held to normal position by a spring, as I, at the front end, which
forces the hook g in contact with the catch g₁ on the piston, and is actuated to
free the piston from this hook by the trigger or lever H, in the usual manner,
as indicated by the dotted lines in Figure 1.
In Figure 1 we have shown the air piston as drawn back and secured by the
sear, in position to fill the air chamber preparatory to discharging the projectile
from the gun, and the actuating lever F thrown back to position to allow of the
forward throw of the piston, which is actuated by the rebound of the spring D,
as indicated by its dotted lines in Fig. 1.
The angle lever F has an upwardly projecting arm F¹ passing through the
stock, and is pivoted to the end of the trigger guard, as at f, and the upper end
of the arm F is provided with a hook f¹ designed to receive the end of the rod E,
[Price 1

page_text: the opposite end of which passes through the head cll of the piston and is arranged
to slide freely through the head, and to draw the piston back, which is accom-
plished by throwing the lever F down to the position indicated by the dotted
lines in Figure 1; and when the piston has engaged the sear the lever is thrown
back to place and the rod E is carried forward through the piston, see Fig. 1,
so that the entire forward throw of the piston is independent of, and without effect
upon the rod.
The catch on the head c¹¹ of the piston is formed entirely around the head
so that it makes no difference what portion of it is engaged by the sear; and the
action of the coiled spring D upon the head is such as to, invariably, cause it to
turn slightly with each stroke of the piston, so that the sear can never engage
it twice, consecutively, in the same place, thus averting the danger of serious
wear upon this bearing.
To secure the barrel to the stock we attach a lug J to the lower side of the
barrel, which passes into a corresponding aperture in the stock, and secure it by
means of a broad headed screw J¹, as shown, so that to disconnect the two' and
take the gun to pieces it is only necessary to remove this one screw, which con-
stitutes, by far, the most simple means yet devised for assembling the parts in
guns of this class.
B' represents a mortise through the stock for the free action of the arm F¹ of
the actuating lever.
To prevent the shot from passing back through the tube a into the large
chamber back of it we simply compress, or lessen the size of the tube at the
extreme back end, in the usual manner of arranging these guns.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. In a spring actuated air gun, a stock, barrel, piston and lever, an actuating
rod slidingly attached to the piston and flexibly attached to the lever, and a
single screw and stux for assembling the parts, an actuating spring arranged to
give a longitudinal and a slightly rotary motion to the piston, a cap upon the
breech of the barrel having a slot for the passage of the piston rod and a strip
cut and turned from the side to form a sight, substantially as set forth.
2. In combination with the barrel, stock and actuating mechanism of a spring
air gun, a detachable cap upon the breech end of the barrel having a slot for
the actuating rod, and a sight cut and formed from the side of the cap sub-
stantially as and for the purpose set forth.
Dated this 22nd day of November 1898.
