This invention relates to improvements in toy machine guns and more particularly to toy machine guns of the spring actuated type which are adapted to fire a plurality of toy bullets in succession and to thus simulate burst firing of actual machine guns.

Toy guns as heretofore proposed, have been of a type adapted for relatively slow firing and other toy spring guns have been proposed in which one spring effected the firing and another more powerful motor spring cocked or stressed the firing spring and then released it. Such latter proposed toy guns did not attain success or commercial use because the more powerful motor or cocking spring acted to re-stress the firing spring before the firing pin or plunger had completed its traverse of firing movement. Other disadvantageous features of former guns included the provisions of a firing pin structure or assembly of such construction that the firing pin had a relatively short stroke of movement. This feature was disadvantageous in that the range was thereby considerably restricted.

The present invention relates to and has for one of its objects the provision of a toy machine gun of the spring operated type employing a firing spring and a motor spring for cocking or stressing it with novel means for correlating and controlling the interrelation of spring actions and firing pin actions whereby with retained depression of the trigger, bullets or projectiles may be discharged automatically in rapid succession to simulate burst firing.

A further object of the present invention resides in the provision of an improved and simple safety device and trigger arrangement for a toy machine gun.

A further object of the present invention resides in the provision of a toy machine gun which will be simple and inexpensive to manufacture and assemble and one which is not likely to get out of order when in use.

A further object of the present invention resides in the provision of a firing pin assembly for a toy machine gun and means for operating it whereby long traverse of firing pin movement may be obtained thereby increasing the range of the gun.

Generally my improved toy machine gun comprises a tripod or stand, which permits variable elevation and variable traverse of the gun. The gun includes the usual stock, grip, and trigger with the main barrel carried by the stock and 25 surrounded by a false barrel simulating the water jacket of an actual machine gun. The trigger is provided with a safety device to prevent accidental firing. The projectiles or bullets are fed automatically in succession into the main barrel 30 from a replaceable clip or magazine. Within the barrel is a firing pin assembly which is normally maintained in advanced position by a coiled tension spring. A hand wound motor spring is disposed upon the stock which is adapted to ro- 35 tate a spider-shaped actuating means or dog. When the trigger is operated the actuating means or dog is released and it is then spring driven by the more powerful motor spring to retract the firing pin assembly and stress its firing spring, 40

whereupon a bullet drops in front of the firing pin. Further movement of the actuating means releases the firing pin, allowing it to move under its ownspring action and eject the bullet from the barrel. Before the firing pin assembly is 45 released for firing movement, latching means is displaced into the path of the actuating means to block movement of the actuating means until the firing pin substantially reaches its forward position. such forward position or just before it reaches such position, the actuating means is again released and the operations repeat until the trigger is released. The details of the gun will now be Upon the firing pin reaching 50 described.

Tripod transverse slot is provided in the tube l3 to limit,

the extent of traverse. If desired, the shoulder plate I5 and the underlying plate l2- 1rnay be graduated to show the extent of traverse of the gun. The foregoing described construction permits traverse of the gun about the tripod support. The tripod legs may be folded up when desired or may be removed from the post when desired.

Quadrant To provide for variable elevation, the post I4 is bored to receive a transverse bolt and wing nut generally designated 16 (see also Fig. '7). This wing nut assembly I6 is adapted to clamp a quadrant frame IT in any desired angular position with respect to the post. The nut may be loosened to permit moving of the gun during firing. 7

Gun

The gun proper is secured in any desired manner to the quadrant frame as by screws extending through the top. of the quadrant frame I'I into wooden stock .19. In Fig. 1, l8 designates the main barrel which is disposed in the stock 19. The barrel 18 at its forward end may, if desired, be surrounded by a cylindrical part 20 adapted to, resemble the cooling jacket of an aci tual machine gun The cooling jacket 20 may be provided with a forward sight 2| which sight may be struck up from the sheet metal of the cooling jacket or otherwise formed. The cooling jacket and stock are suitably apertured to secure a replaceable clip or magazine designated 22. preferably has a stop lug 23 thereon to stop the clip in proper position. The ,clip may have an open slot at one side as shown at 24 (Fig. 1) to show the number of bullets therein. The bullets or projectiles 25 may be of Wood or rubber or of any other suitable material. If desired, a sliding gravity weight 26 may be employed to aid the descent of the bullets in the clip. Such weight may be guided in suitable slots in the front and rear edges of the clip. Such slots limit the descent of the weight in the clip and permit withdrawal of the weight with the clip. The bottom of the clip or magazine is opened to permit the :descent of the bullets through a slot 26a in the 7 upper half of the main barrel [8. Disposed within the main barrel I8 is a firing pin 28 which in forward position (stop position) assumes the position of Fig. 1. This firing pin is. drawn to this position by a firing spring 29 which may be hooked at its forward end to the stock as shown in Fig. 1. The firing pin may be slidably guided to the rear or to the right of the magazine by extending the stock material into pro-x imity with the pin. The rear end of the firing pin has secured to it a firing butt 30 preferably having the configuration shown in Fig. 4 and secured between shoulders 3| on the firing pin and a nut 32 which also affords a rear anchorage This clip may be made of sheet metal and for the firing spring 29. The firing pin and firing butt assembly may be termed a firing pin assembly.

Secured to the stock by suitable fastenings, such as by screws, is a main spring housing 33. Such housing preferably is a sheet metal structure comprising side plates 3301., a cross plate 33b, tab or ear portions 330 and a bottom closing strip or band 33d. The side plates 33a. form a pivotal support for a winding spring arbor 34, preferably having a squared end to receive the usual winding key not shown. The arbor 34 has a ratchet 35 and a main motor spring 36 secured thereto. The opposite-end of the motor spring 36. is secured to a spring post 31. Cooperating with the ratchet 35 is a combined winding and driving pawl 38 which is pivoted upon an actuating member or dog 39. The actuating dog is preferably of the three-arm type to provide compactness of construction. The three arms of the actuating dog are respectively designated 39a, 39b and 390 and preferably have the end con-. figuration shown in Fig. 4.

Q ci atQ Q x r ment Pivoted on a bracket 40 fixedto one of the side plates is an oscillator or escapement member 4|. This: oscillator has the configuraton shown in plan' in Fig. 6 and includes a rear camming edge 4 la, a front camming edge 4 lb and a latching portion He provided with a shoulder Md, which servesv as a limit stop for the firing pin butt'30.

Trigger, grip and safety device The grip or handle 42 depends from the rear of the main stock. The trigger 43 is preferably a strip of flexible metal shaped as shownin Fig. 4. Pivoted tothe stock is an automatic safety device 44 having a tail 44a overlying a resilient extension 43a from the trigger and having another extension 44bunderlying the trigger. The resilience of part 430. normally keeps part 44 in the position shown in Fig. 4. The relations and proportions of the safety device and trigger are such that in order to obtain access to the trigger to operate the same, the safety device must first be manipulated by depressing part 44b from the position shown in Fig. 4 to the position shown in Fig. 5. This will afford space infront of the trigger for the insertion of the trigger finger between the safety device 44 and trigger, thereafter the trigger may-be operated. It will be understood that with the parts in the position shown in Fig. 4 there is insufficient space for the insertion of the finger to operate the trigger. (Note dotted line finger outline on this view.) After firing upon removal of the finger, the safety device automatically resumes the safety position shown in Fig. 4. Restoration of the safety device to this position is effected by the resilient member 43a.

Rear'sight Any suitable rear sight may be provided. Such sight may comprise a bracket 50 (see Fig. 2) having a plurality of sight openings 50a affording different sight elevations.

Operation ulates the safety latch and inserts the trigger 7d finger ready to pull the trigger. The various parts are now in the relation as shown in Fig. 4, except that in this figure the safety latch 44 is shown in safety position. The trigger extension 432) prevents clockwise motion of the actuating dog, such extension 3317 intercepting arm 3%. On pulling the trigger to the Fig. 5 position the actuating means or dog is released and moves clockwise under the power of the main motor spring as indicated by the arrow. The dog 3% moves from the Fig. 4 position through the dotted line position (see Fig. 5) to the full line position (Fig. 5) This motion of the actuating means or dog stretches the firing spring 29, retracts the firing pin assembly, including the firing pin and allows a bullet to drop from the clip in front of the firing pin when the firing pin is fully retracted. It will be appreciated that the hand wound motor spring 36 is more powerful than the firing spring 29. While the firing pin assembly is moving rearwardly under the power of the main motor spring the firing pin butt 30 will engage the rear camming edge 4 la of the oscillator or escapement and cam it from the full line position (Fig. 6) to the dotted line position. Clockwise rotation of the actuating dog continues until a dog arm such as 39a assumes the relation shown in Fig. 5. A slight further movement will permit the dog arm to clear the firing butt whereupon the firing pin assembly may be drawn forward by the now stretched firing pin 29. It will be noted that before the firing pin assembly moves forward that the latching nose 4|c of the oscillator 4! will be in the path of a following arm of the actuating dog and prevent further clockwise movement of such actuating dog (note the dotted line position of the oscillator in Fig. 6). However, upon forward movement of the firing pin butt under the action of the firing spring, such butt will ultimately engage the forward camming edge llb of the oscillator and rock it out from the dotted line position (Fig. 6) to the full line position so that the latching nose of the oscillator will again be 'displaced out of the path of the next arm of the actuating dog. The foregoing operations will then repeat provided the trigger is maintained tripped.

Burst firing obviously may be secured with the above described mechanism so that actual machine gun rapid fire may be simulated. Firing may be terminated at any time by release of the trigger which will allow the extension 43b to block motion of the actuating dog. The arrangement described provides comparatively long movement for the firing pin, thus affording good range. The inter-control between the firing pin assemblage and; actuating dog which is provided for by the oscillator or escapement member 4! provides for proper succession of operations and in particular, provides means to prevent the actuating dog acting to re-stress the firing spring pin or to return the firing spring assemblage to cocked position prematurely. With this inter-control, the firing pin always makes its complete traverse to the right to eject a bullet before the actuating dog is released to again recock the firing pin assembly.

By properly proportioning the parts, increased movement and increased range may be attained.
