To all whom it may concern:
Be it known that I, VVILLIAM F. SCHMIDT, citizen. of the United"Sta tes, residing at IVyandotte, cbunty of IVayne, State of Michigan, have invented a certain new and useful Improvement in Toy Guns, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use 'the same, refer ence being had to the accompanying drawings, which form a part of this specification. I I
My invention relates to toy guns and objects of my improvements are to provide an apparatus that is efficient, cheap to construct, and assemble, and that affords accessibility, as more specifically pointed out hereinafter. I
I secured this object in the device illustrated in the accompanying drawing in which Figure l is a side View of a toy gun embodying my invention.
Fig. 2 is a vertical section through the axis of part of the barrel of the gun.
Fig. 3 is the inverted plan view ofFig. 2.
Fig. it is a section on the line IV, IV, Fig. 2. j I
Fig. 5 is a perspective view of the thimble forming a partition and the connecting means between the main and auxiliary barrel.
Fig. 6 is a plan view of a gun embodying my invention, taken apart to economlze room in transportation and packing.
Fig. 7 is a section similar to Fig. 2, to an enlargedscale showing a modified construction.
Fig; 8 is-a section on theline VIII, VIII, Fig. 7*.
Fig.9 is a view of the formed sheet from which the shell of the thimble, Fig. 7, is rolled.
Fig. 10," is a plan View o-f' the thimble of Fig. I
a is the main barrel and is the stock. I), is a piston which, in the kind of gun contemplated, is thrown forward by a spring 6 to compress the air in front of 1t, and there by to. give the im ,ulse to theprogectrle.
In the so call po-pgun, the projectile is of cork lightly inserted in the muzzle of the barrel a. which cork is thrown forward,
as theprojectile, when the piston acornpresses the air between it and said cork.
My invention enables one to cheaply and readily transform such popgun toan eife'ctive air'rifle, which is readily accessible for the purposes hereinafter pointed out. i
(Z is a thimble stamped outof sheet-metal open at one end and closed-at the other end,
except for the inwardly,projecting,axial,
tubular portion (Z 45* is a lug 'exten'd'i'ngradially outward from the peripheral wall of the thimble. Thethilnble b is placed in the muzzle of the barrel a with its, closed inner endrinward and forming a partition d at the muzzle of the barrel c, and a second partition, f extending across the, interior of the false barrel, or outer casing, 0 at a distance from the partition, f 7 0 (Fig. 3), i
.is an L-shaped slot cutinto the wall of the false barrel 0 extending inward from its in ner end and then'at right angles. The false barrel, 0 is shoved overthe protruding end of the thimble d, the lug d passing into the slot 0 and is then turned about its axis, so that the lug 03* shall be engaged in the lateral extension, ofs'aid' slot, as shown in Fig. 3, thus forming a bayonet auxiliary barrel in place.
e is a felt washer fitting within the bore of the thimble 03, cut away at its center to-pass around, and 'fit closely against the outer wall of the projection d, and lying against the inner wall of theclosed inneifend; or partition d of said thimble." e isan annular washer fittingwithin the barrela, and lying against the closed end of partition d ofthe thimble d.-
When. the. auxiliary barrel a is adjnsted to position as above described, the inner barrel i is caused to pass over the-tubularro;- jection d with a close; lit, and engage against the washer e, toforma tight .jpi nt,
Now if a shot; m of thedi-ameter of the bore of. the barrel.- f isplaced in said; barrel and allowed to fall to-the inner endthereof, when it gets to the slight contraction of the joint holding the (Z it will be stopped and held in. this position by friction. If new the piston b is thrown forward by the spring 6 it will compress the air in front of it, and thereby propel the shot 112. through the barrel 7 and project the same from the muzzle of the bar rel.
In toy air rifles of this kind, the shot m sometimes becomes lodged in the position shown, so that it cannot be thrown out by the action of the air in front of the piston. By the above construction, the auxiliary barrel 0 may be readily removed and a small rod or ramrod used to dislodge the shot m. I r
' The piston Z) requires occasional oiling to keep it tight and in good working order. In the above construction it is easily accessible for this purpose by removing the auxiliary barrel, as above described, and'oiling the piston through the tubular projection (Z I By the above construction, economy of space in packing for transportation is also secured. The auxiliary barrel 0 may be removed or placed in the box or receptacle 00 beside the rest of thegun, as illustrated in Figure 6, so that a shorter receptacle may be employed.
Instead of forming the thimble d by pressing the same out of a single sheet, it may be constructed as illustrated in Figures 7 to 10 inclusive, in which the shell ha is rolled from a blank (Z00, (Fig. 9), into one edge of which is cut the slot elm, and the opposite edge being cut away, as indicated at aim This sheet is then rolled to a cylindrical form, bringing the two edges, (Z50 and clos together, as shown in'Figure 10. The cutaway portion, doe then forms an entrance passage to the L-shaped slot, and the cutaway portion, d00 forming the laterally extending portion of said slot.
The inner end of the cylinder (la is closed by the cut portion, d Q'fitting and secured in itsend. i
The engaging lug is formed by cutting out a portion of the metal of the cylinder 0 and turning the same radially inward to form the lug This lug enters and en gages in the L slot above described in the usual way.
What I claimisr r 1. The combination of a barrel, a thimble fixed in said barrel so that its end shall form a stationary abutment, said thimble having one end closed with an aperture in said closure having its walls extended to form a tubular extension therefrom for the-purpose described. I 1 v 2. The combination of a barrel, a thimble fixed in said barrel so that its end shall form a stationary abutment, said thimble having one end closed "with an aperture insaid 01.0
sure having its 'walls extended to form a tubular inwardly projecting extension therefrom for the purpose described.
8. In an apparatus of the kind described, a main barrel, a fixed partition in said barrel provided with an axially extending tubular portion and an auxiliary barrel adapt ed to be removably secured to said main barrel and form an extension thereof, saidaux iliary barrel having a bore with walls engaging the walls of said tubular portion with a tight joint.
4; In an apparatus of the kind described, a main barrel, a fixed partition in said bar- -re1 provided with an axially extending tubular portion and an auxiliary barrel adapted to be removably secured to said main barrel and form an extension thereof, said aux iliary barrel having a bore with walls engaging the walls of said tubular portion with a tight joint, said tubular portion projecting into said bore.
5. In an apparatus of the kind described, the combination of a main barrel and an auxiliary barrel, a thimble extending into said main barrel and fixedly secured therein so as to have a part projecting therefrom, said auxiliary barrel fitting over and engaging the protruding portion of said thimble to form an extension of said main barrel and to secure said auxiliary barrel in position, said thimble being closed at its inner end except for an aperture therein for the purpose described, said aperture having walls forming a tubular extension, engaging the walls of the bore of said auxiliary barrel.
6. In an apparatus of the kind described, the combination of a main barrel and an auxiliary barrel, a thimble extending into said main barrel and secured therein so as 'to have a part projecting therefrom, said auxiliary barrel fitting over said thimble to form an extension of said main barrel, said thimble being closed at its inner end except for an aperture therein for the purpose described, said aperture having walls forming a tubular extension, engaging the walls of the bore of said auxiliary barrel and extending into the same. I
7. In apparatus of the kind described, a thimble formed of a circular sheet having the slot (500 in one edge, and the cut-away portion daf in the other edge, the same being shaped to form the L slot and rolled into a cylindrical form. r
