TOY MACHINE GUN
John W. K. Heppner, New York, N. Y., assignor
to Louis Marx & Company, New York, N. Y., a
corporation of New York
Application April 17, 1934, Serial No. 720,952
17 Claims. (Cl. 46-175)
This invention relates to toys, and more par
ticularly to toy guns, especially simulated ma—
breech portion l2, the barrel portion M, and the
chine guns.
muzzle portion l6 of a machine gun.
The primary object of my invention is to gen
5 erally improve toy guns. A more particular ob
ject of my invention resides in the provision of a
toy gun having spark producing mechanism for
causing a shower of sparks at the muzzle, sound
producing mechanism, and motor means for con
10 tinuously operating the sparking mechanism and
the sound producing mechanism. The motor
may be controlled by a trigger, and the continu
ous shower of sparks in response to pulling the
trigger makes the toy realistic in operation.
Further objects and features of my invention
15
center about the construction of the machine gun
mechanism, and include the location of the motor
near the muzzle of the gun; the provision of a
compact and appropriately shaped motor adapted
20 to be there mounted; simpli?ed sparking mech
anism including a holder adapted to support a
pyrophoric or like element against an abrasive
wheel with light gravitational pressure; complete
removability and replaceability of the sparking
25 element through the top of the gun muzzle; a
simulated sight on the gun muzzle normally con
cealing the sparking element but movable to pro
vide access to the ‘sparking element; the pro
vision of an improved noise making hammer
30 which is large yet disposed longitudinally of the
gun barrel and which is adapted to produce a
loud sound and realistic vibration of the gun, yet
operable by a motor of ‘only moderate torque;
, and the provision of an improved tripod which
35 is inexpensive to manufacture, and collapsible
to small dimension.
To the accomplishment of the foregoing and
such other objects as will hereinafter appear, my
‘invention consists in the toy machine gun ele
40 ments and their relation one to another, as here
inafter are more particularly described in the
speci?cation and sought to be de?ned in the
claims. The speci?cation is accompanied by a
drawing, in which:

-
The body B is shaped to simulate the
The machine gun includes spark producing
mechanism S, noise making mechanism N, and a 5
motor M for operating both the sound and spark
producing mechanisms. The motor M is dis
posed at the muzzle portion iii of the gun, thereby
simplifying the drive of the spark producing
mechanism S. The motor frame is shaped with 10
converging top and bottom sides 20 and 22 (Fig.
2) so as to ?t compactly and accurately within
the generally triangular part 24 (Fig. 1) of the
machine gun body. Referring to Fig. 2, the
spring winding shaft 26, the spiral spring 28, 15
and the large-diameter gear 30 actuated there
by, are all located at the large part of the motor
frame. Gear 30 is then connected, through a
step-up gear train of progressively smaller gears,
to the abrasive wheel 32. Speci?cally, gear 30 20
meshes with a pinion 34 fast with a gear 36 mesh
ing with a pinion 38 fast with a gear 410 meshing
with a pinion 42 ?xed on the shaft 44 of the
abrasive ,wheel 32. The abrasive wheel 32 is
preferably disposed with the top of its periphery 25
substantially at the longitudinal center line of
the gun barrel and muzzle IS.
A pyrophoric or like element 50 is secured to
a holder 52 consisting of a bent strip of sheet
metal, as is best shown in Fig. 5, the opposite end
of the holder being formed into an inverted T
54 which is received in a bayonet type slot 55 in
the top of muzzle IS. The muzzle is cut away at
58 to receive the holder 52, and the latter is 35
freely movable so as to rest lightly and gravita
tionally upon the abrasive wheel 32. This light
contact prolongs the operating life of the pyro
phoric element. The sparking mechanism is con
cealed by a simulated sight 60 which is supported 40
on the muzzle by front tongue and slot connec
tions 62 and back tongue and slot connections 64-.
The front tongues'slip into the mating slots with
a snap engagement, while the rear tongues are so

-
Referring to the drawing and more particularly
to Fig. 1 thereof, the toy machine gun comprises
55 a machine gun body B detachably mounted on
shaped as to provide pivoting of the sight 60 on 45
the gun. The sight 60 may thus be elevated, as
shown in Fig. 4, thereby providing access to the
spark producing mechanism.
The pyrophoric element 50 is readily changed
when worn out, by elevating the sight 60, elevat- 50
ing the holder 52 until the element 50 is above
the muzzle, and thereupon swinging the holder
52 approximately at right angles to the gun bar
rel, whereupon the inverted T end 54 is readily
elevated out of the bayonet slot 56. Substitute 65
2

elements 50 are preferably supplied already
mounted on the holders 52.
Because of the proximity of the spark producing
mechanism to the muzzle of the gun, a shower
of sparks is emitted from the gun. However, if
it is desired to _further expose the shower of
sparks. the side walls of the muzzle may be cut
away to form elongated windows 66.
The sound producing mechanism includes a
10 hammer or sound producing element 10 of sub
stantial length. This element is preferably bent
from stiff, heavy gauge strap metal. In its pres
ent form it is pivoted in the motor frame on a
spindle ‘I2. The main gear 30 of the motor
meshes with a pinion 14 which rotates an appro
prlate cam 16.
A cam follower ‘I8 is connected
rigidly with the hammer ‘l0, and this cam follower
preferably is bent to form the ears 80 through
which the spindle ‘I2 passes. It will be evident
20 that as the cam ‘l5 rotates in a clockwise direc
tion, the hammer ‘I0 is elevated and abruptly
released, whereupon its free end 82-strikes against
bent arcuately to form the barrel I4 and corru
gated to form simulated cooling ?ns I20. The
ends of the single piece of sheet metal are then
directed downwardly to form the sides I22. The
muzzle portion I6 is also formed of a single piece
of sheet metal bent downwardly to form the side
walls I24 which enclose the forward part of the
motor frame. At the end of muzzle portion I6
the sheet metal sides are bent inwardly to form a
closed cylindrical barrel, as is indicated at I26 10
in Fig. 1, the meeting edges being secured to-'
gether by appropriate tongue and slot connec
tions. The open bottom edge of the barrel and
muzzle portions I4 and I6 are closed by a single
piece of sheet metal I28 which extends forwardly 15
from the breech portion, then slopingly upwardly
beneath the muzzle portion, as at I30, and ?nally
extends upwardly to the muzzle, as at I32. This
piece of metal is appropriately ?anged and se
cured to the side walls by suitable tongue and 20
slot connections.

If desired, the impact or" the hammer may be
30 sharpened by the provision of a light leaf spring
88 mounted in cantilever fashion at the end 90
in the motor frame and extending over the ham
mer. An intermediate portion 92 of the hammer
ls bent upwardly so as to bear against the spring
when elevated by the cam ‘I6. The spring is dis
placed only slightly and adds but little to the
motor load, yet greatly accelerates the fall of the
hammer.
_
The motor is controlled by a trigger 94 prefer
ably located at the breech end of the gun and
within a handle 96. The trigger is U-shaped
and is normally held inwardly or forwardly by a
compression spring 98. One arm of the trigger
is extended forwardly, as shown at I00, and runs
45 through the body of the gun to the motor. At
the motor a simple brake I02 (Figs. 2 and 3) is
provided, pivoted at IE4 and connected to the
control wire I00 at I06. The brake encompasses
the sparking wheel shaft 44 with an arcuate slot
I08 which is eccentric with respect to pivot I04.

of sheet metal and are channel shaped except for
feet I48 at the lower ends and cylindrical parts, 30

is provided with a wire loop I52 having ends I54
sprung sidewardly into the machine gun body, and
2. depending pin I56 adapted to be received in
the central opening I42 of block I40. It will be 35
understood that for shipment the machine gun
body is readily elevated from the tripod, where
upon the member I52 is adapted to fold with
pin I56 parallel to and lying against the bottom
of the machine gun body.
The machine gun .40
may thus be packed in an'elongated rectangular
carton closely ?tting the machine gun body. The
tripod is readily disassembled by pulling the legs
from the block. The legs may then be nested to
gether and placed in the carton receiving the ma 45
chine gun body.
Ample room is also provided ’
within the box for the block I40 as well as the
winding stem or key I60, at the muzzle portion of
the gun, because the rectangular breech portion of
the gun is wider than the muzzle portion thereof. 50
The parts are so disposed that when the trigger .
