'I'Clams` It is the object of this invention to. provide. a toy machine gun pistolwith the handlezpermanently attached for operating the gun, but so arranged that it can be moved from an operative position, where it can be easily moved by hand I It is a further object of theinventionto provide av toypistol with timed feeding.. and. firing mechanism, preferablyutilizinga. perforated strip of ammunitiontwithout a 'trigger but with an. operating handle so that it may be fired rapidly or 'continuouslyas v`in a. machine gun.

Theseand otherffeatures will.l appear fromv the following descriptionf takenl in connectioni with I thedrawings.

The pistol. has anouter casing formed of two 25 .sides,. a lefthand side. I and a righthandv side 2,

joined. together by means of bolts or screws 3. The. numera-l-4 represents the butt or grip end ofthe pistol, While the numeralv 5 represents the barrel. I'Ihe-part or side 2 has therein one-half 6 of A an ammunition chamber, While the other half is formed in. aremovable and pivoted part 'I.. This part. 'If is pivoted to the. two sidesby means of a lug. 8, which. has ay hole thereinv through which one of. the bolts or screws 3 passes. This part 'I .hasextending laterally therefrom a projection la,

which is engaged by the nger of the operator so that thepartisheld inclosedposition but may be readily-removed for opening the chamber when 40 thenger is-removed from. the opening provided therefor between the. ammunition chamber and thegripor buttof the pistol.

In. theammunition chamber is a pin or projectionllfadapted to support aroll I0-of ammuni- 45 tion. formed of a stripII. On theinside-of the casing and. on the. side. I is a boss I2, which has extending therethrough. ahole I3 for receiving a plunger I4. This plunger has on its outer end a limiting shoulder I5.' and. on its innerv end a 50 head. I6 adapted to. be. engaged by oneend of a coilspring IIY. which surrounds the plunger and hasitsother end in engagement with the boss I2l for causingn the plunger to move inwardly. Within. the casing andY between the boss I2 and.v 55

ed to receive a crank member 23 for rotating the Y anvil. This crank has on one end a handle 23a, f

while its otherr end is slightly bent at 24to form a neck part which projects through the hole in the hub into the cone-shaped cavity. v

This neck part has on its end a ball 25 which is sufficiently large to prevent the handle becoming displaced by the ball passing `through the hole vin the'hub. This ball has von one side thereof a cam member 26.,y This ball and cam member are in engagement with the head on the inner end of the plunger I4, andthe spring I'I tends to hold the headv in engagement with the ball 25 and the cam member 26. The handle'has thereon a lugZI adapted to t in eitherv one of the notches 22 so that the anvil may be rotated by v a rotation of the crank. f,

' vFigures v17 and 18'show the crank in a; position with the lug in one of the notches 22 so that a rotation of the crank Will rotate the anvilfand 'feed the ammunition strip. When the crankv is in this position the handle 23a is in the position v shown in Figure 4. The crank may be swung so that the lug 21 is withdrawn'from the notch 22,

and wheny so withdrawn ythe crank may assume a position substantially parallel with the sideof f the pistol, as shown in Figures 1, 2, and 3. When the crank is infthis position the pistol maybe carried in the pocket, or it may be placed in'y a carton or casev provided therefor. v

The spring I'I forcing the head I6 against the cam member 26 tends to hold the crank in in' operative position. Whenthe crank is in `operative positionA the head I6, acted upon by the spring I'I engaging Vthe ball, tends to hold the crank in operative position for rotating the anvil.

The anvil is in the formof a hollow drum and has on its periphery a plurality of radially extending projections 28 adapted to extend through holes 29 in the strip of ammunition II. These holes 29 for receiving the feeding projections alternate with ammunition charges 30. The rotation of the anvil will cause the ammunition strip to advance, due to the projections extending through the holes 29. As the strip of ammunition advances and is red the used end will pass out through an outlet 3| provided therefor in the top of the pistol.

For the purpose of iiring the ammunition a hammer 32 is provided which is Vpivotally mounted upon a pivot member 33 in the-form of a pin extending from the inside of the righthand side of the pistol casing., For the purpose of urging the head of the hammer toward the anvil a spring 34 is provided. This spring intermediate its ends is coiled and ts over the pivot of the hammer while one end is engaged by a postA 35 and its other end ts into a pocket 36 provided therefor in the hammer. This spring and its relation to the hammer are shown in Figure 12.

The end of the hammer remote from its pivot is provided with a head 31 adapted to engage'the ammunition for ring. Adjacent the head and between the head and the pivot of the hammer is a lifter arm 38A adaptedA to be engaged by the projections 28 on the rotatable anvil for the purpose of withdrawing the'hammer so that under y 'the inuence of the spring 34 it may again engage the anvil to re the ammunition after the pro'r jectcn has passed beyond the lifter arm in the course rof rotation. f f

For the purpose of stripping the used end of the'strip of vammunition from the rotatable anvil a spring 3 9 -is provided, which is supported at one end in the barrel of the pistol by means of sup,- porting projections or lugs 40, and has on its other end astripper 4I closely engaging the periphery of the anvil and provided With a notch 42 through which the projections pass during the rotation vof theV anvil. The pistol is provided with av finger guard 43 located between the ammunition chamber and the butt or grip of the pistol.

The present pistol is a machine gun type of pistol, in which the ammunition is fed from a yroll by meansvof a rotating anvil having projections thereon adapted toy pass through openings vin the v strip of ammunition for feeding purposes. rThe projections on the vrotatable anvil serve not only as instrumentalities for feeding the strip vof ammunition but they serve to operate the hammer vby engaging the lifter armv38.

rWhen this arm is engaged by any one'of they projections 28` the hammer heady is withdrawn f from the anvil and at the same time the strip of ammunition is fed forwardly s0 one of the charges 30 is brought forward to be engaged by the head of the hammer after the projection passes beyond the lifter arm so that the hammer will be brought into impact with the ammunitionr strip, due to the actio'noithe spring 34.v

Thefammunition chamber, as will be observed from an examination of Figures 9 and 12, is located on thev side of the anvil opposite that part on which the ammunition is tired.v This prof tects the ammunition and also makes it possible to provide an ammunition chamber that is accessible and readily closed by means of the member I pivotally connected to the barrel end of the pistol. This member 'I also has a projection adapted tobe engaged by the finger of the operator so that the member I will be held in a position to close the ammunition chamber and protect'the ammunition located therein.
