The present invention relates to cap magazine means for a toy gun. One of the principal objects of the present invention is to provide a gun into which a rolled strip of percussion caps may be inserted with reasonable assurance that accidental discharge of a cap while the fingers are closethereto may not occur.

A further object of the present invention is to provide a cap-holding magazine which may be automatically raised to a loading position upon release of a magazine-holding latch.

A further object of the present invention is to provide an improved, rugged mechanism of the character described made of a relatively few, sturdy, easily assembled parts.

The foregoing and other objects and advantages of the present invention may be more readily ascertained by inspection of the following specification taken in connection with the accompanying drawing wherein like numerals refer to like parts throughout, while the features of novelty will be more clearly pointed out in the appended claims.

In the drawing,

Fig. 1 is a view in elevation of the frame of the gun with the cover removed to expose the working mechanism, the view showing the relationship of the operating parts when a cap has been discharged and the trigger has returned to its normal position;

Fig. 2 is an enlarged, partial view similar to Fig. 1 but showingthe magazine in opened position and the trigger retained at half-cock for safety;

Fig. 3 is a partial view of the rear of the frame simulate the cylinder and breech portion of a revolver, a handle portion [2- and a barrel portion l3. The gun is completed by meansof a complementary cover 2'0 which isretained in place by rivets or screws passing through suitable openings in the cover (not shown) and in the frame, such as indicated at M, I 5, I6 and I1.

The trigger guard I8 is mounted upon the frame l0 and the front sight (not shown) is mounted upon the muzzle portion of the cover 20, the arrangement being such that the trigger guard through a notch in the frame I!) so that the finger portion 23 thereof lies within the trigger guard. The trigger part extends inwardly beyond the pivot and the inner end thereof is provided with a pair of vertically spaced projections, the lower one of which constitutes a lock Spur indicated at 24 and the upper one of which constitutes a sear indicated at 25. The trigger is provided with a generally fore-and-aft slot 26 into which the pivot 2| projects, the slot lying within a transverse, cylindical boss 21 on the trigger piece. A cap feeding pawl 28 is pivotally mounted at 29 on the trigger piece immediately below the lock spur 24, the feed pawl extending forwardly at an inclination above the boss 21. A projection 30 on the lower surface of the feed pawl engages the surface of the boss 21 so as to hold the feed pawl in a normal, inclined position illustrated in Fig. l. A spiral spring 3| is attached at one end to the projection 30 and its opposite end is attached to the forward edge of a hammer 32 pivoted on the frame at 33. The spring is under tension and passes about the boss 27 in contact with the lower and forward surfaces thereof, then passes diagonally upward behind the pawl 28 to its point of attachment to the hammer 32. The arrangement is such that when the hammer is in its released position the spring exerts a rearward pull on the boss 21 of the trigger piece so as to hold the inner end of the trigger piece rearwardly with the forward end of the slot 25 engaging the pin Zl. The spring also urges the trigger forward about pivot 2| and returns the trigger when released. The trigger is retained in its normal position by a portion of the trigger engaging the forward end of the notch in the frame through which it projects. The spring 3! also holds the projection 3i! against the lug 27 so that the feed pawl is poised to engage a paper strip 3d having caps thereon, and caused to slide the strip upwardly across the surface of an anvil 35 when the trigger is actuated. The hammer 32 is also forced forwardly about its pivot 33 by spring 3| so that the striker portion 36 of the hammer may explode a cap positioned in alignment therewith by the feed pawl. A hammer limitinglug 31 projects from the frame in position to engage an abutment on the hammer and prevent further forward movement of the hammer if the trigger should be pulled while the anvil is raised as illustrated in Fig. 2.

The hammer is provided with a lock toe 38 extending radially forward from the pivot 33 to a point above the lock spur 26 when in normal released position as shown in Fig. 1. When the trigger is rotated by pulling the finger piece 23 rearwardly the spur 24 engages the toe 38 to raise the hammer. As soon as the hammer has been raised to a considerable extent beyond the position illustrated in Fig. 2 the spring 3|, which has been increasingly tensioned, snaps the hammer forwardly to cause the striker portion thereof to discharge a cap positioned on the anvil, the hammer thereupon coming to rest in the position illustrated in Fig. 1. The lock spur is now above and overhanging the lock toe, but the trigger may return to its normal position under the infiuence of the spring 31 because of the lateral displacement thereof permitted by the slot 26.

As the trigger is released and begins to rotate forwardly about the pivot 2| the inner end thereof will be moved forwardly by the toe 38 so that the trigger pivot 2| becomes relatively positioned in the rear end of the slot 26 until the lock spur clears the lock toe, whereupon the spring 3! will return the trigger to its normal position illustrated in Fig. 1 in readiness for the next firing action.

The upper tip of the feed pawl 28 is normally spaced slightly from the lower surface of the anvil so as to permit manual shifting of the strip 34 if the hammer should be slightly raised. However, when the trigger is pulled rearwardly, the tip of the pawl engages the strip of caps and presses the same against the anvil. Continued movement of the trigger toward the rear causes the pawl to push the strip upwardly across the face of the anvil, the extent of feeding movement thereby accomplished being such as to position a fresh cap in alignment with the striker face. The striker face is preferably transversely ridged so as frictionally to hold the strip in position during the first portion of the returning movement of the feed pawl.

The strip 34 is supplied in a roll which may be mounted in a magazine comprising a tapered pin projecting inwardly from a roll mounting flange 4| afiixed to the anvil 35 and to a magazine plate 62 pivotally mounted in the frame and normally closing the magazine opening, the mounting thereof comprising a triangular lug 53 depending from the front end of plate 52 and a pivot pin 44 mounted in suitable bearing bosses on the frame If] and cover 20 and passing through the lug. A magazine latch bar 45 projects through the side of the frame and normally engages a latch notch 66 in the forward edge of flange 4|, the outer end of the latch bar being accessible and so arranged that it may be manually shifted forward to release the magazine. The latch bar 35 is biased toward holding position by a coil spring 61 tensioned between the inner end of the latch bar and a point on the lug 43 beneath the pivot M. When the latch bar is released the spring 4'! contracts to swing the magazine upwardly about pivot 64 to its open position as illustrated in Fig. 2 so that a fresh roll of caps may be mounted thereon and trained across the anvil.

In order to increase the simulation of a real revolver and. to eliminate the danger of an accidental discharge while loading a fresh strip of caps, the striker face 36 may be held rearwardly from the anvil 35 by moving the hammer to half cock position. For this purpose the hammer is provided with a cocking spur 50 projecting rearwardly in position to be engaged by the thumb. Upon pulling the hammer rearwardly by means of the cooking spur the lock toe 38 engages the rear face of the sear 25 on the inner end of the trigger and moves the trigger forwardly as permitted by the slot 26 until the toe clears the sear, whereupon the spring 3| will snap the trigger rearwardly to position the sear beneath the toe. Upon releasing the hammer the toe will engage the upper surface of the sear to hold the hammer at half-cock as illustrated in Fig. 2. The hammer may be released from the half-cock position by pulling the trigger, whereupon the lock toe will first drop onto the lock spur 24 and thereafter will be fully raised and released in the usual manner, or the hammer may be held back by means of the cocking spur and lowered gently to its released position when the trigger has been pulled rearwardly to its limit position, thereby removing the scar and lock spur from the path of the lock toe.

The latch bar 55 comprises a narrow bar having a forwardly hooked inner end 10 with which the spring 4? is engaged. The intermediate portion of the latch bar rests in a rearwardly facing groove H in a lug 12 projecting laterally from the frame Ill and providing a fulcrum against which the angular inner end of the latch is held by the spring 41. The outer end of the latch bar 55 projects through a latch opening #3 in alignment with the groove H, the opening being of sufiicient length in the longitudinal direction as to permit the outer end of the latch bar to be swung rearwardly by the spring 41 to cause the latch bar to engage notch 46 in the flange 4!. The outer tip of the latch bar 45 comprises a grooved finger portion 14 of such size that it may not be drawn through the opening I3. In assembling the mechanism the spring 41 is hooked to the lug 43 and the latch bar 45 inserted through the opening 13 and properly positioned in the groove H. The free end of spring 47 may now be hooked to the tip I0 of the latch bar while the magazine is raised so that the spring is relatively untensioned. Thereafter the rear end of the magazine plate 42 may be depressed so that it enters the space provided be tween the frame It and the cover 20. The forward edge of the flange 4| engages the rear edge of the latch bar 45 and cams it forwardly into the groove ll until the latch bar snaps into the locking notch 46, as illustrated in Fig. 4. The magazine will remain in closed position until the tip 14 of the latch bar is pushed forwardly to clear the latch bar from the notch 46, whereupon the spring 41 will contract and swing the magazine upwardly about pivot 44.
