Application August 5, 1947, Serial No. 766,189

This invention relates to cap pistols, and, has

for an object to provide a repeating cap pistol employing a strip of ammunition in roll form having spaced caps which will, by pulling on a trigger, repeat firing as a machine gun until the roll has been consumed, and, which can also be used to fire, or detonate a single cap, or any other number of caps less than that contained in a full length strip, by merely actuating the trigger with a finger.

A" further object of the invention resides in providing means for guiding the ammunition cap strip from the roll to a feeder element for feeding the cap strip to and between a stationary anvil and a resiliently supported reciprocable hammer head, which feeder element is actuated by means of a suitable train of gears driven by means of a sprin motor and controlled by trigger actuated means controlling reciprocation of the reciprocable hammer head.

The above and other objects and features of novelty of this invention, such as construction, combinations and relations of parts by which the objects are attained, will become apparent when referring to, for a :better understandin of the invention, the following specification, taken in conjunction with the accompanying drawings, wherein:

Fig. 1 is a top plan view of the cap pistol.

Fig. 4 is a viewpartly in section, looking in the direction of the arrow in Fig. 2, and showingthe train of gears, the spring motor and the capstrip feeder element.

Fig. 5 is a rear elevation of the cap pistol.

In carrying my improved cap pistol of the repeater type, into practice, I employ a casing consisting of two casing members designated, generally, as I and 2. Each casing member includes and forms a handle, or butt portion 3 and a barrel, or muzzle portion 4. The casing also includes a trigger guard 5 which may be integral with one of the casingymembers, or, it may be separable by being a part of, or suitably connected with one or both of the casing members. The lower end of the guard 5 joins with the butt portion 3 of the casing, -as illustrated. The casing members I and 2 may be connected by suitable fastening devices such, for instance, as screws 5.

1 Claim. (01. 42.-57)

The casing is designed to house and conceal the operating mechanism and to contain the operating mechanisms such, as clearly shown in one embodiment thereof in Figs. 2 and 3. Part of the mechanism is mounted or carried by a strip likeplate I, which constitutes a support suitably carried by the casing member 2.

The operating mechanism supported by the plate 1 includes a suitable clock-spring 8, the inner end of which is secured to a winding shaft 9 mounted at one end in an opening in the plate 1 and passing therethrough, and mounted near its opposite end in an opening in a strip plate l0 supported at opposite ends by and suitably secured to suitable pins II and I2. The outer end of the coiled spring 8 is connected, or anchored to the pin H between the plates I and Ill. The end of winding shaft 9 is provided ad- Jacent the plate ID with a square end portion l3 receivable in an opening M in the butt 3 of the casing member I and is adapted to receive a winding key l5 for winding the sprin 8. The lower wall of the butt 3 is provided with an opening l6 through which the stem portion ll of the key 15 may pass to be frictionally' held, when not in use, by means of a suitable supporting member l8.

A suitable ratchet wheel I9 is secured to the winding shaft 9 adjacent the casing member 2 and is controlled when winding the spring by a pawl 20 pivoted, as at 2|, to a gear 22 of suitable pitch diameter and rotatably mounted on the winding shaft 9 between the pawl 20 and the plate 1. The pawl 20 is normally held between two teeth of the gear H! by means of the free -end of a suitable spring 23 secured at its opposite end to the gear 22 mounted on the shaft 9. The gear 22 meshes with a gear 2d of suitable pitch diameter which is fixed to a suitable sleeve l2 mounted on a pin l2 supported by the plates 1 and ID. A gear 26 of suitable pitch diameter is fixed to the sleeve 12' mounted on pin I2 to rotate with gear 24 and meshes with- A cap strip feeder element, such as a wheel 32 having a single peripheral tooth 33- having a pointed end 34, is mounted on the shaft 3| to'be rotated by the gear 80, and the feeder wheel 32,

is provided with a laterally projecting crank-pin 35 located near the edge thereof, as clearly shown in Figs. 2 and 4.

Projecting into the path of travel of the crankpin 35 is a suitable finger 35 supported on the free end of a suitable leaf spring 31 anchored at its opposite end to a suitable support 38 carried b the barrel, or muzzle portion 4 of the casing member 2. The crank-pin 35 rides counterclockwise upon the upper face of the finger 36 until? it rides off of the finger below the shaft 3:. The crank-pin 35 rides on the finger 36 fOr approxi mately ninety degrees of its path of travel, thereby causing the finger 35 to be lowered, moving:

therewith a hammer head 33 carried by the finger 36 due to the resiliency of thespring' 3 h.

This arrangement retracts the. hammer head 39. from contact with a stationary anvil 40 which may be the inner face of the top wall of the.

casing member 2, or an insert carried thereby in front of thefeeder wheel 32; When. the crankpin- 35: rides off of the finger 35; the spring :3?! causes the hammer head 39 tossuddenly' strike the anvil 40. and to detonate ammunition caps 4-! spaced along a cap strip 42 with; or-wi-thout per forations 43 between each ammunition cap.- along. the cap strip=42-..

The: cap strip 42 is in' roll form, and it. is 11otatabl y mounted on a suitable supporting; pin 44 secured at one endto thecasingmember 2. The cap strip 4Zfis threaded between: two spaced 4.5: and 416- and the top:- wall of. the casing adjacentth-e upper edge of: the feeder; wheel: 3-2,. and is under thewtension: of a suitable leaf; spring 41? to cause the strip 42 to ride under. pressure,. or: tension onsthepin- 45. Thetooth-33011 the feeder: wheel 32 engages inhth'e spaced holes; orpe'rforations 4-3; inthe cap; stripv 42-, and" as the feeder wheel: 32 rotates. it moves the cap strip: 42 for ward one station, or thedistance betweenspacedi ammunition caps each: time the:- crank-pin. conrpletes one revolution, due to the unwindingaction: of the clock spring 8'. For ea'ch revolut'ion ofthe: feeder wheel 3-2, the cap strip: 42: is. moved: forward". one station. to. bring the succeeding: ammuzn-ition captothe stationaryanvil; 40: tobe detonated by the sudden release of the hammerhead- 39: as. the spring supported finger see is released from: riding action onthe crank-pin: 35; Where the: ammunition strip 42 isv not provided with: perforations, the pointed end 34 of" the feederv wheel tooth 33 will perforate thestrip l'fi betweeni the ammunition caps carried? thereon to' advancetheammunition caps onthestrip 43. to detonat i'ng position under the stationary: anvil 4E7;

Tocontrol? the action of the feeder Wheel and the hammer head 39-, I employ a trigger 487i pivoted; as at 49 to the casihg-member-Z. A pin:- 50 1s suitably hinged; asat 51-; to the trigger-4%- and the free end thereof ismount'ed to ride inanopening 52 in the gear-supportin shaft '28; The pin is provided with a shoulder 53 and-there is a suitable coiled spring 54 encircling-the pin: 50 disposed between-the shoulder 53=and-thegear shaft 28. The upper end.- of thetrigger48 ispro-- v-id'ed with a head 55 which is adapted'toengagethe-underface of the springsupported finger- 36: directly under" the hammer head 39 to' preventthe rotation of the feeder wheel32 and-crank pin 35-until-pu1ling finger pressureis appliedtothe trigger 48 to release the head 55 from contact with the spring supported finger 36. When the trigger '48 has been pulled to release the trigger head from contact with the spring supported finger 36 supporting the hammer head 39, the hammer head 39 will be free to reciprocate and strike the anvil due to the action of spring 3'1, thereby detonating the ammunition caps along the cap strip as they are fed or advanced to the stationary anvil 40. One ammunition cap can be detonated at a time by quickly releasing the trigger 4.8, or by holding the trigger 48 in, the entire roll of caps can be detonated in rapid machine gun fashion, or two, three, four or any other number of caps can be detonated by finger control of the-trigger 48.

The top wall of the casing is provided with an opening 5%? through which the fired end of the ammunition cap. strip can be fed through as fast as the caps are detonated. The opening 56 is adjacent. and beyond the stationary anvil, as shown in Fig. 1.
