10 Claims. (01.46-178) The invention relates to toy guns of the character of pop guns which make a report without discharging a projectile. It is the object of thev invention to obtain a simplified construction which can be manufactured at low cost and which when fired produces an exceptionally loud report. To this end the invention consists in the construction as hereinafter set forth.

My improved gun is of a form which simulates a fictitious structure assumed to have extraordinary powers. This form is one in which the muzzle end of the gun is flared and is provided 39 with an upwardly extending fin forming a sight.

It is further provided with a flaring guard between the barrel and the frame of the gun and the frame portion is of peculiar shape. To produce a gun of such form together with a. pop mechanism at low cost I have designed a structure having the following elements.

The barrel A is formed from a single sheet metal blank fashioned to form as an integral portion thereof a flaring muzzle end B and the 40 upwardly extending forward sight C. The edges of the blank are brought together at the top of the barrel and the sight portion C is formed by correspondingly shaped flanges which arespot welded to each other to retain the barrel in closed position. Within the barrel inserted through the muzzle end thereof is a seamless air cylinder D which is held from displacement either forwardly or rearwardly by detents A and A struck inwardly from the barrel. The forward end of this air cylinder has an inwardly extending flange D terminating in a forwardly extending flange D surrounding an aperture of smaller diameter than the cylinder. In front of the flange D is a metal disc E and in front of this disc is a tapering helical spring F, its small end being at the rear and bearing against the disc and its large end engaging the flaring portion of the barrel. This spring can be inserted through the muzzle end and is then held from displacement by ears G on. the

end of the barrel blank turned over the outer 5 end coil on the spring. The rear end of the barrel blank has a cut away portion A which in the formed barrel forms an opening in the lower side thereof. Through this opening is inserted the plunger H for engaging the cylinder D being 1Q preferably formed of two metal discs H and H with an intermediate felt disc H The plunger shank I extends rearwardly and also has a portion I extending forwardly through the opening surrounded by the flange D and adapted in the 15 normal position of the plunger to displace the disc E from seating on said flange. The rear end of the shankis formed with a return bent portion I which bears against the upper surface of the barrel to form a guide and which has a down- 2Q wardly extending portion I for engagement with the. trigger sear. Surrounding the plunger I bearing at its forward end against the disc H is a helical spring J which can be inserted with the plunger I-I through the opening A in the barrel 5 and which after insertion is engaged with a downwardly extending tongue J struck inward from the barrel. This forms a spring abutment so positioned with respect to the length of the spring as to place the latter under the desired tension. 3Q

Pivoted in the rear end of the barrel on a cross pin K is a combined trigger and sear K. This has the downwardly extending portion K and the horizontally extending portion K which latter bears against the lower end of the portion 5 I of the plunger shank. The sear is formed by a notch K at the rear end of the portion K adapted to engage with the portion I The frame of the gun is formed by two complementarystampings L having the desired form 4 and having integral therewith the trigger guard L. These stampings are fashioned to embrace the barrel and to form a closure L for the rear end thereof, the barrel being secured to this portion by rearwardly extending tongues A A on 45, the barrel blank extending through apertures in the portion L At their forward ends the frame stampings are held to the barrel by portions L thereof which closely fit the barrel. These portions fit in an annular recess formed by the hub 5 from displacement by outwardly struck detents 55 A. Thus the frame can be quickly assembled with the barrel by first engaging the portions L with the member M and then the tongues A with the apertures in the end portions L and finally turning said tongues to lock the parts in this position. The frame may be further locked by one or more lugs L at the periphery soldered, welded or clinched to each other.

Pivotally connected to the frame is a handle portion N which also forms the means for cooking the gun. This handle portion is formed of two complementary sheet metal stampings having segmental portions N embracing the trigger and the downwardly extending portion I of the plunger shank I. At the end of these segmental portions is a cross pin N adapted to engage with the portion I The handle is pivoted upon a pin secured to the lower portion of the frame and so positioned that when the handle is pulled forward into the dotted position the pin N will engage the portion I drawing it rearward until it registers with the notch K forming the sear. The sear will snap into engagement with the portion I by the resilient tension of a spring P which is arranged between a portion A at the rear of the barrel and a lug on the downwardly extending portion K of the trigger. A boss Q on the frame engaging a corresponding recess on the handle N holds said handle in normal position.

With the construction as described, to cock the gun the handle N is pressed forward, turning on the pivot O and causing the pin N to draw the plunger shank I rearwardly, compressing the spring J and finally engaging the portion I on said shank with the sear K The handle is then returned to normal position in which it locks by the engagement of the boss Q with the recess Q. In this position the plunger H is at the rear end of the barrel D but when the trigger is pulled to disengage the sear the plunger will be moved for- Ward by the tension of the spring J. Just before reaching the forward end of the cylinder D the projecting end I of the plunger shank will strike against the disc E forcing the latter away from its seat on the flange D and by releasing the compressed air in the cylinder making a loud report.

One important feature of my construction is that the enclosure disc E is formed of metal and I have discovered that with such material or with material of a like hardness the report produced is much sharper than where a soft gasket of leather or similar material is between the disc and its seat.

Another important feature of the invention is the construction of the barrel frame and handle which facilitates quick assembly. As has been described, the barrel extends completely through the frame and the complementary sections of the latter are secured to the barrel by sliding their forward end portions L into the annular recess M while the rear ends are held by the tongues A extending through the apertures in the portion L The frame members are further connected to each other by the lugs or ears L and these as preferably formed and as shown in Fig. 5 have a clamping engagement with each other. Thus specifically one of the complementary frame members L has formed thereon notched ears L adapted to receive a down-turned ear L on the other member which is subsequently clinched as shown in Fig. 8. Inasmuch however, as the forward ends L are clamped to the barrel when they are entered into the recess M this would interfere with the engagement of the down-turned ears L with the notched ears L I therefore form the tongues A of greater length than the tongue A so that the former may be engaged with the aperture in the end portion L and one of the frame members before the forward portion L is engaged with the recess M This will temporarily hold the frame member in position while the handle N is placed thereon and engaged with the portion 1 of the plunger shank. The second frame member is then placed over the barrel engaging the ears L with the notched ears L after which both frame members may be slid upon the barrel to engage the portions L with the recess M This will hold the parts together, and finally the ears L are clinched as shown at L Fig. 8, and the tongues A and A are bent downward to permanently hold the parts together. Thus the frame members are secured by their engagement with the barrel and the handle is secured by its engagement with the frame members. The bifurcated portions N of the handle also form a guide for the downturned portion I of the plunger shank, holding it from turning and guiding it into engagement with the sear notch.

What I claim as my invention is:
