THOMAS J. NASH, OF LINCOLN, NEBRASKA.

TOY GUN.

T 0 all whom it may concern Be it known that I, THOMAS J. NASH, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented a new and useful Toy Gun, of which the following is a specifieation.

This invention relates to that class of toy cannons or guns adapted to produce sounds by compression of air and the subsequent breaking of a paper head or cover of an air chamber and primarily my invention seeks to provide a pneumatic gun of the character stated of a simple and economical nature that may .be conveniently and safely operated by a child and which is adapted for being used like an ordinary gun or rifle and for producing sounds resembling the report of explosive firearms.

With further objects in view that will hereinafter appear, my invention consists of a toy gun in which are embodied the peculiar and novel features of construction all of which will be fully described and specifically pointed out in the appended claims and illustrated in the accompanying drawings in which Figure 1 is a perspective view of my toy gun, the same being shown as in use. Fig. 2 is a longitudinal section thereof parts being in perspective and the manner of tearing off the ruptured paper ribbon portion being also illustrated, and the firing plunger at its back or loaded position. Fig. 3 is a perspective view of the slotted plunger or piston. Fig. 4: is a longitudinal section of my gun, the plunger or piston being at the firing position. Fig. 5 is a side elevation of the gun the parts being in the position shown in Fig. 2. Fig. 6 is an inverted plan view of the forward end of the gun. Fig. 7 is a detail view of the clamp. Fig. 8 is a detail perspective view of the muzzle end of the gun.

In the practical application of my invention I form the stock or butt portion either of cast or sheet metal, and while I have shown the same as formed of a solid piece it may be made in two halves and secured together in any well known manner.

The front end of the stock is tubular to receive the tubular extension or barrel 2,'preferably a thin tubing as shown. If desired the extension 2 may be cast integral with the stock or butt portion 1 and then bored out to the desired size.

Serial No. 755,834.

15 designates a piston or plunger. It has a longitudinal slot 16 that extends from a solid front end 21 to the solid rear end 20 a pin 13 that takes through the bifurcated pendent lugs on the front end of the tubular or barrel member 2.

Trigger 29 includes a forwardly extending arm the front end of which terminates in a catch that is in the nature of a beveled pawl 28, with which the beveled edge 27 of the rear end of the piston engages in the manner hereinafter made clear.

The spring 31 at all times forces and holds the catch or pawl 28 to a piston engaging position and it is forced down only when the piston or plunger is pulled to its loaded position, by reason of the beveled edge 27 of the piston riding against and forcing the beveled catch or pawl 28 to allow the rear solid end of the piston to pass over the said pawl 28 which latter when released, springs up into the slot 16 of the piston and engages the front face of the solid post 20 and thereby holds the piston and its firing spring 31 back to the loaded position, as best shown in Fig. 2.

Lever let has the usual hand-hold 14 and its forward end has the usual pull finger 17 that projects up through the bottom of the slot 16 to engage with the rear end 20 of the piston, and by reason thereof, when the lever 1-l is swung down to the dotted position, see Fig. 4, the piston or plunger is forced back until the catch pawl 28 interlocks with the end 20 of the piston, as is clearly shown in Fig. 2.

After the piston is adjusted by the lever 14, to the position shown in Fig. 2, the said lever 14: is returned to its locked or shooting positio-n,see full lines Fig. 4.

The lever 14 in my construction of gun besides performing its function of adjusting the piston to its loaded position serves as the means for adjusting the clamping means which holds the paper riblow its fulcrum pin 13.

bon that is ruptured when the gun is fired. The said means, in my construction of gun, comprises a forked wire member consisting of two parallel side rods 99, and a cross rod 90 which latter is formed by bending the wire strand of which the said forked member is constructed, into a loop and bending the said loop at right angles to the side rods 9, to bring the cross rod 90 in a plane below the gun barrel and low enough to fit through an aperture 91 in the lever 14, at a point to the rear of and slightly be The side rods 9 extend forwardly one at each side of the gun barrel, and their front ends extend beyond the muzzle end of the barrel.

7 designates a clamping washer provided with diametrically opposite'apertured ears 10 that receive the ends of the rods 99, the said rod ends being threaded to receive the clamping nuts 9292. At the rear side, the washer is formed with an inwardly projected annular flange 8 that receives a gasket 6 of rubber, leather or other suitable material, and which is held in place by the rods 99. The washer 6, as is best seen in Figs. 2 and 4, is of a slightly greater thickness "than that of the annular flange 8, such rela tive sizes of the flange and the washer being provided that ample compression surface of the washer is provided to efiect the desired air-tight clamping of the ribbon before it is possible to draw up the flange 8 against the end of the gun barrel.

The outer end of the gun barrel is formed with an annular abutment flange 5 having radial cars 50 and they are grooved as at 51 to form seats for the rods 99.

37 designates a roll of paper and it is rotatably supported on a wire bail or hanger 38 attached to and pendently supported from the muzzle end of the gun barrel 2 and it is so disposed, relatively to the abutment 5 of the barrel that the ribbon can be conveniently passed up over the abutment 5 and over the muzzle of the gun when the clamp device 7 is moved to its forward position.

By reason of the peculiar construction and cooperative arrangement of the parts so far described and shown in the drawings, when the lever 14 is thrown forward the clamping washer and its gasket are forced forwardly and away from the end of the barrel 2 to allow for freely drawing out the end of the roll of paper to pull the punctured portion away from the gun barrel and a new section of the paper over the said barrel as is' clearly shown in Fig. 2, it being also clear that as the lever 14 is swung back to the shooting position, as in Fig. 4, the rods 9-9 pull the washer 7 and the gasket 6 toward the abutment face 5 of the barrel and thereby firmly clamp the paper, air-tight, over the muzzle of the barrel, as

in Fig. 4. It is understood that the action of returning the lever 14 to its back or shooting position takes place at the same time, the spring and the plunger are forced back requiring as it were, but one operation to load the gun. Pulling the trigger 29 releases the plunger or piston, which in my construction is fitted on its forward end with a cupped leather washer 23 held in place by a screw and washer 29.. The piston or plunger when released by the action of the trigger 29 is shot forward by the spring 31 and in doing so compresses the air in the barrel between the plunger and the paper, which forms a diaphragm over the end of the barrel, and which, by the air compression, is caused to burst, allowing the air to suddenly escape with a loud report similar to that of the ordinary firearm.

41 designates a supplemental or shoulder gun stock and it is formed of a stout wire strand bent up to the desired shape and formed with an upper hook 42, which is first hooked through a hole 43 in the butt 1 and with a lower hook 44 that is sprung into a locked engagement with a hole 45 in the bottom of the butt, as is clearly illustrated in Fig. 2.

From the foregoing taken in connection with the drawings, the complete construction, the manner in which my invention is used and its advantages will be readily understood.
