TOY PISTOL.

Application filed June 30, 1921. Serial No. 481,722.

T 0 all whom it may concern:

Be it known that I, SILAS l3. Bnowrna citizen of the United States, and residing at Qincinnati. in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Toy Pistols, of which the following specification is a full disclosure.

My invention relates to a toy pistol of a type adapted to explode caps of a roll of conventional ammunition tape. An object of the invention is to provide a toy which will faithfully simulate a modern I automatic firearmthe caps being exploded internally of the pistol casin combustion products escaping through the barrel. to very materially improve the tape feed and controlling mechanism, but more particularly the mechanism is devised to accurately and invariably feed the cap to a predetermined position on the anvil. A portion of the hammer acts to protect the nextadjacent cap to be fired from the back-fire of the exploding cap. The hammer also acts against an anvil strip to prevent back-- lash of the tape, when the tape feed pawl recedes. The feed mechanism is so organized as to lnsure the-feed pawl always operably engaging with the tape just in rear of the caps. Another OlJJGCl) of the invention is to eliminate from the combinationthe ordinary guide and backlash spring heretofore employed. Another object of the invention is to provide an improved frame construction adapted for convenient assembly of the operating mechanism. Another object of the invention is to very greatly simplify the construction and arrangement of the parts.

The detail escapement forthe han1mertrigger mechanism is also a feature of the improvement. .Another object of" the improvement is to provide means whe-reby'the engaging end of the feed pawl'is normally supported upon a frame member out of contact with the ammunition tape and only moved into feed contact'therewith when the trigger is operated. Other features and ob.- iects of the invention will appear in connection with the description ofcombination drawings forming a part of this specification, wherein Fig. l is an elevation of my improved pistohthe side to which the mechanism is at- Another object of the invention is tached, being broken away to more clearly show said mechanism..

Figs. 9, 10, 11 and 12, are diagrammatic views showing successive tape-feed operations.

Fig. 13 is a view of the skeleton frame.

The pistol shell or casing is composed of two sheet metal members forming a housing, hinged at the top or upper barrel margin'GO, the margins 70, at the bottom edges of the butt are detachably snapped together to close the pistol casing. It is only necessary to show one of these shell members, and accordingly I have shown in Fig. 1 the shell member 1,providing a supporting pin 2, for the ammunition roll 3, and it also is formed with apertures designed to register with certain of the frame project-ions tosupport and secure the frame, the hammer, and trigger fulcrum posts providing two of said projections.

The assembly frame is of skeleton form (see Fig. 18) having the upper anvil memher 4, and side frame section integral therewith, comprising section 5, extending rearwardly from theanvil and upon which, in rear of the anvil section 4%, and spaced vertically and horizontally therefrom, is a horizontally extended shoulder 6, (see Fig. 9). The side portion ofthe frame is completed by the two downwardly extended members 7 and and bottom horizontal member 9, connecting members '7 and 8, and providing a frame having only one side member upon whichthe pistol parts are to be assembled, the other or open side of which is to be closed, and supported by .the shell member.

Later-ally projecting from the lower side frame portion are two horizontal spacing and spring tension sustaining posts 10, 11,

which rest against the shell casing 1 when the pistol is assembled. There are also formed on said side portion of the frame, trigger and hammer fulcrum posts 12, 13, respectively, the free ends being riveted to and supported by said casing member.

An important structural and functional characteristic of the improvement lies in the formation of the interior under surface of the anvil member 4 of the frame, wherein there is an anvil formation 14-, in registration with the hammer, the member in rear thereof having a cut out portion 15, at the rear end of which is formed a depending abutment lug 16. The member 5 in rear of lug 16 is also formed with a cut away portion 17 providing a tape-entering throat in spaced relation with abutment shoulder 6.

T o the front end of member 5 is secured a resilient anvil strip 18, rearwardly extended beyond member 5, and occupying a position between the hammer and anvil and between the rear end of the anvil member 5, and shoulder 65, the rear end of this strip being upturned for a finger grasp. This is really an anvil covering strip whose functions are determined by its relationship to the anvil, hammer, lug 16 and shoulder 6, and cut away formations 15, 17, and it is actuated to perform these functions by the pressure of the feed pawl 19.

It will be seen that the space between the adjacent margins of the member 5 and shoulder 6, form a throat for introducing the ammunition tape. In normal. position the end of the anvil strip 18 is above and out of contact with the shoulder 65, enabling the tape to be threaded under the spring 18 through the clearance provided by cutout portion 17, and into position for operative control by the tape feed mechanism, i. e. the feed pawl 19 and anvil strip 18. The upper surface of shoulder 6 forms a rigid. support for the tape, furthering its accurate delivery into the next position wit-h respect to the pawl feed and anvil spring.

Upon the hammer fulcrum post 13 of this frame is placed the hammer 20, held normally against the anvil by spring 21. In rear of the exploding head of the hammer there is a V-like notch providing an upwardly projecting detent 22, which when the tape is in firing position impinges against the tape and anvil spring 18 just in rear of the anvil upon that yielding portion of spring 18, which bridges the lug l6 and the anvil formation 14 of member 5. This detent acting against the spring resilience at this point, and impinging the tape, prevents backlash and also constitutes a barrier between the forward cap 23 upon the anvil, and the next cap 2 1- at the rear, preventing any back-fire, and as stated, serving to prevent any backlash of the tape when the feed pawl 19 is returned to normal position. This hammer is provided with an extension 25 below the fulcrum for cooperation with the trigger.

Further, it is quite important that the hammer head, directly in front of the detent 22, be formed with a downwardly extending vent 410, (see Fig. 1) opening into the interior of the frame, for the escape of gases, preventing the escaping gases when exploding from reacting upon the hammer, or upon the sensitive anvil spring 18 adjacent the anvil.

Trigger 26 is mounted on fulcrum post 12, and is held in normal initial position. by coil spring 27, having a rearwardly extending terminal end 28 for engagii'ig and influencing the feed pawl 19.

Said trigger 26 has'an extension member 29 rearwardly of the fulcrum. having a notch 30, upon which is pivotally mounted a ratchet feed pawl 19, formed with an aperture 31. through which passes the said terminal end 28, of the trigger spring, the feed engaging end of the pawl resting normally on the under forward surface of the shoulder 6, free from any impingement engagement with the tape, but in position to move forward with the trigger and engage the tape.

The normal position of the mechanism is indicated in Fig. 1, wherein the tape has been loosely inserted through the threat 1'? and lies against the spring 18. The initial movement of the trigger moves the feed pawl to a position shown in Fig. 9, wherein the hammer is slightly raised from the anvil, and the pawl slightly engages the tape.

As shown in Fi 10, further movement deflects the spring 18 and the pawl takes firm hold upon the tape. As the pawl moves forwardly from its position, shown in Fig. 10, and passes beyond the lug 16, and as the angle between the pawl and tape becomes more acute, and because of the rounded engaging edge 19 of the pawl, the same slips along the tape, as shown in Fig. 11, to engage the cap 2a, the spring 18 having been deflected to swing its rear end toward the shoulder 6, thus imposing a slight tension upon the tape by pressing it towards and against said shoulder, to form a brake upon the tape while the pawl slips to cap-engage ment. Further movement of the pawl. to its limit of movement positions the cap 23 in firing position upon the anvil 1 1 and im mediately thereafter the same is fired.

Inasmuch as the pawl, after having passed the lug 16, is capable of being disengaged from the strip to slide forwardly to engage the cap, and inasmuch as the passage of the pawl beyond said lug deflects the spring to form a brake for the tape, the accurate positioning of the forward cap 23 upon the anvil is assured. This structure has overcome all difficulties heretofore experienced in an attempt to accurately and consecutively position said caps.

At the instant ofexplosion, (see Fig. 12), the hammer detent 22 acts as a barrier between the two forward caps, and at the same time, as explained, it impinges the tape against a yielding portion of the spring 18, throwing its outer end against the tape and so holds it in this position during the return of the pawl to initial position.

The hammer and trigger extensions 25, 29 respectively, provide cams which operate in intersecting arcs, the camming formations constituting an escapement, enabling the trigger to cock the hammer and release it for fire, the hammer and trigger returning to initial position independently. In this initial position, the member 29 has a shoulder or cam surface 32, enga'gingwith the cam surface 33,0f the extension 25, so that as the triggermoves, its surface 32 rides downwardly of the hammer cam surface 33 until the hammer is fully cocked, at which time the lower end of the cam 33 is opposite the release formation 3 of member 29*, which allows the arm 25 to pass forwardly over the said member 29 thus allowing the hammer to snap to firing'position.

It will be seen that the anvil spring, the hammer and its spring, the trigger, its spring, and pawl feed, can be readily assembled in relation to this skeleton frame,

and the assembly securance is completed by attaching this frame to the shell casing, the pawl feed being the key of the assembly formation. 7 I

It will readily be seen how extremely simple and reduced in number are these parts, namely, the support frame comprising the anvil and shoulder for entering the tape, the anvil spring, hammer and hammer spring, trigger and trigger spring and pawl, simply seven pieces.

Moreover, the frame and these parts can be made of very small dimensions and of light metal or alloy admirably adapted for die casting the parts' The tape control, due to the unique movement of the spring 18 under the pressure influence of the feed pawl, in relation to the abutments and cutout sections provided by anvil member 4, is fully diagrammed in Figs. 9 to 12.

The great difficulty with previous devices of this kind has been the irregularity of fire, due to the fact that no means were provided for giving the pawl a definite feed position in relation to the'caps of the tape, and that the feed pawl isconstantly impinging upon the tape.

As explained, the caps which are on the under side of the tape, virtually constitute ratchet teeth for the definite cooperation with the pawl, r

It is obvious that a greatmany changes could be made; from the exact 'detafilsof the preferred embodiment illustrated, without a substantial departure from theteachings the spring 21 is wound so as to be capable of compression bearing intermediately between the frames 1 and the hammer and about the hub extension of the latter. This prevents the hammer from being shifted transversely upon its axis when its extension 25 engages the inclined surface 34: ,ofth'e trigger for cocking release. This coil portion of the spring forces the hammer automatically into its normal position for a subsequent trigger cooperation. 1
