TOY FANNER PHSTGL John W, Ryan, Los Angeles, (Jalif.

Application March 11, 1957, Serial No, liitltl 9 Claims. (Cl. 425fi) This invention relates to a cap firing mechanism, particularly to a safe, conveniently loaded, cap-firing gun adapted to realistic simulation of the six-gun of the Wiid West.

The six-gun closely associated with the Wild West is so called because it is a revolver, employing a rotatably mounted cylinder provided with six cartridge chambers set in the cylinder. The cylinder turns so as to bring each cartridge one after the other in line with the barrel of the revolver, in which position it is discharged by the action of the hammer.

In normal operation, the hammer of such a pistol is cocked as a separate operation by the thumb of the gripping hand before firing the gun by squeezing the trigger; this sequence is repeated separately to fire each individual shot. Some Western gun fighters, however, developed a method of firing wherein the hammer was operated to fire shots rapidly by pushing the hammer back with the free hand and releasing it with the same free hand, permitting it to strike and fire the cartridge, while the gun was held in the other hand. By this method of firing the gun, known as fanning, it was possible to fire the gun more rapidly than by manipulating the hammer and trigger separately and sequentially for each shot individually and using only the hand holding the gun. This offered a marked advantage in gun duels and gun fights where firing speed was of prime importance.

The six-guns associated with the Wild West, and the various modes of operation employed with them have been so dramatized and made familiar to children that they have become conscious of hitherto neglected differences in appearance and operation between toy cap guns and actual cartridge-firing revolvers. Thus, a cap pistol designed to simulate the six-gun and the method of firing employed by some of the gun fighters of the West should employ a rotatably mounted cylinder that rotates in proper relation to the firing of the gun; this gun should be capable of being fired by fanning the hammer in a manner resembling the actual fanning operation of an authentic six-gun. Accurate and reliable indexing of the caps with the associated anvil and revolver cylinder when thus operated rapidly is necessary to avoid misfiring. A practical toy gun using caps should be convenient and easy to load, and should be designed to be loaded with rolled strips of caps, or else directly loaded with standard large single caps.

In the interest of safety, it is desirable that the structure and mechanism of a cap-firing toy be so designed as to provide for enclosure of the cap explosion within the toy, and to eliminate short, unrestricted paths between the cap explosion and the outside of the toy through which injury could come to the user by the cap explosion. While this can be accomplished through complete enclosure of the hammer and anvil, another solution must be sought where it is desirable to employ an exposed hammer for the other reasons. Tedious, time-consuming and dilficult loading operations are characteristic of some 23%,28? Patented Dec. 36, 1958 of the safer but less typical toy gun prior art. Some such prior art approaches the combination of exposed hammer operation and enclosure and control of cap explosions by employing individual specially trimmed caps placed in individual cups serving as secondary hammer surfaces together with individual anvils, each of which must be individually prepared and loaded in the gun, and subsequently removed, disassembled and cleaned to reload at'ter firing. Toy guns more typical of the prior art of more practical and easily loaded types, employing exposed hammers such as would be necessary for realistic simulation of many actual cartridge-firing guns, are characterized by exposure during the instant a cap is fired by the edges of the anvil and hammer surfaces which meet to explode a cap. Such guns permit direct escape at these edges of the flash, blast and smoke of the cap explosion in a manner that is both unsafe and unrealistic.

In the interest of realism, it is desirable that a toy gun project smoke from its barrel when fired. In toy guns typical of the prior art, the positional relationships between hammer, anvil and barrel, as well as the direct escape of cap explosion products and lack of controlling confinement, militate against efiective conduction and projection of the smoke from the cap explosion out through the muzzle of the barrel; this is a problem par ticularly in guns employing exposed hammers. In like manner, the direction of the serrations, where they are used, on the hammer and/ or anvil of prior art toy gun mechanisms, is transverse rather than longitudinal with respect to an axis parallel to the sides of the gun, and is not as conducive to longitudinal smoke conduction and projection in the direction of the barrel axis as is the use of longitudinal serrations.

Accordingly, it is an important object of my invention to provide a cap firing mechanism wherein the firing ac tion of the cap is the cylinder of the gun so that the feed ing and the firing of caps in a strip is related to the rotation of the cylinder very much as the firing of cartridges is related to the rotation of the cylinder in a genuine revolver.

Another object is to provide a cap-firing revolver employing a mechanism with which the hammer of the revolver can be actuated for firing the caps rapidly by fanning the hammer independently of actuation of the hammer by the use of the trigger in a manner very closely resembling the fanning operation employed for rapid firing of six-guns by the Western gun-fighters.

A further object is to provide a cap-firing revolver employing a cap firing mechanism in which the effects of manufacturing tolerances are minimized, thus permitting caps to be fed, positioned and fired in rapid succession with a high degree of precision for improved reliability of firing operation, minimizing the number of misfires.

It is also an important object of my invention to provide a cap firing mechanism wherein the cap explosions are safely enclosed to avoid injury to the user, adapted to the employment of an exposed hammer, and suitable for facile loading and firing of strips of paper caps.

A further object is to provide a cap firing mechanism wherein the cap explosions are safely enclosed to avoid injury to the user, adapted to the employment of an exposed hammer, and suitable for direct loading and tiring of standard large caps supplied in sheets.

Another object is to provide a cap-firing gun wherein effective conduction and projection of the smoke from the cap explosion out through the gun barrel is achieved through controlled confinement, suitable positional relationships between the hammer, anvil, gun body, barrel and other parts, and by the use of hammer and/or anvil serrations parallel with the sides of the gun.

An additional object is to provide a cap-firing gun pivotal axis. of the hammer means. 7 places the axis of rotation of the anvil preferably approxiwherein the feed mechanism transports a strip of paper caps transversely from one side of the gun toward the other in a direction perpendicular to the axis of the gun barrel and/ or the plane of movement of the hammer, and in plan s parallel to the gun barrelaxis.

Additional objects will become apparent from the following description:

In general, my invention comprehends the provision of a cap firing mechanism comprising a pivotally mounted hammer means and a rotatably mounted anvil means operatively associated with the hammer means, and oriented with its axis of rotation substantially perpendicular to the This arrangement mately parallel with the axis of the gun barrel. in the case of the six-gun, the rotational axis of the cylinder of the revolver also is approximately parallel to the axis of the barrel of the revolver and the cylinder preferably is connected for rotationwith the anvil to simulate the rotating cylinder of a six-gun.

Indexing means preferably are associated with the hammer means for, rotating the anvil and cylindercooperatively with the cocking action of the hammer means whether by actuation with a trigger or by fanning the hammer without the use of the trigger. Pawl means also preferably are employed for rotation and indexing of the cylinder and anvil in operative association with the hammer means for actuation thereby independent of the 'trigger means. Braking and indexing means providing positive braking action in coniunction with rotational indexing, designed to minirnize the effect of manufacturing tolerances on location of caps for firing are preferably emploved to enable fanning and indexing to be carried out rapidly and precisely with a minimuni'of misfiring,

Synchronizing means preferably are employed for accomplish ng the feeding and firing of caps in strips in such relationship with the rotation and indexing of a revolver cylinder that as the strip of caps is fed to advance and stop to present successive caps in the strip at the firing position on the anvil, where they are fired while stationary by the action of the hammer, the cylinder is cooperatively advanced to and stopped at successive cylinder chamber positions.

Feed means are provided for the cross feed of caps in strips to carry them away from one side of the gun toward the other, feeding them in a direction perpendicular to the gun barrel axis and in planes parallel to the gun barrel axis.

Enclosing means are provided by the gun body and hammer means to enclose effectively and control the explosion of caps between anvil means and partially externally exposedhammer means, restricting to a minimum the transmission out of the top and/ or rear of the gun of flash, blast and smoke accompanying the cap explosion.

Hammer means partially'exposed externally of the as sociated gun body are employed to meet anvil means within the gun body to fire cans in a plane approximately perpendicular to those sides of the hammer means having edges then exposed externally of the gun body, so as to permit efiective enclosure of cap explosion within the gun body to be completedv by the hammer means closing its own entry aperture in the gun body and avoiding exposure external of the gun body of all edges of the meeting faces of hammer means and anvil means. The face of the anvil means met by the hammer means has all of its edges recessed deeply within the gun body and is preferably oriented horizontally with respect to the gun body, in a plane oriented to the direction of the desired enclosed conduction of smoke from the cap explosion out to the gun barrel muzzle, with each such faces edge farthest from the ham- ,rner pivot so oriented as to be nearest the direction in which smoke is to be so conducted. The aforesaid plane 4 of contact preferably is horizontal and parallel to the axis of the gun barrel.

Cap explosion face serrations in the hammer means and/or anvil means are oriented in the direction of the aforesaid desired smoke conduction, preferably parallel to the sides of the gun and aligned with a substantially clear desired path of enclosed smoke conduction to the muzzle of the gun barrel.

Longitudinal apertures corresponding to the cartridge chambers of an actual revolver are provided in the cylinder, the uppermost of which apertures at each of the cylinders successive stopping positions is aligned between the gun barrel at the front and the cap firing position on the anvil behind the cylinder proper, to conduct smoke from the cap explosion through to the barrel.

Al'errratively, anvil means operating cooperatively with hammer means to explode caps employ one or more apertures in a stationary anvil face fixed to the gun frame which are smaller in at least one dimension than the width of the cap explosive charge, conducting the flash, blast and smoke of the cap explosion out through the other side of the anvil, which is preferably aligned with a substantially clear desired path of enclosed smoke conduction out to the muzzle of the gun barrel.

A. more detailed description of a specific embodiment of my invention is given with reference to the drawings, wherein:

Figure 2 is an enlarged partial view showing details of the cap firing mechanism of my invention;

Figure 3 is a vertical sectional view taken as along the line 3-3 of Figure 2;

Figure 4 is an enlarged fragmentary View showing the hammer and anvil means in a firing position;

Figure 5 is an enlarged fragmentary view as viewed from the reverse side of Figure 2; and

Figure 6 is a fragmentary view ofa perforated strip of caps.

In the drawings, the body M is made to simulate that of an actual six-gun revolver, including a handle llll, hollow barrel l2, sightlS and trigger guard E4. The mechanism of my invention is mounted in the gun body 10 which is preferably composed of two halves joined together along a longitudinal axis, as shown.

An anvil drum 16 is mounted for rotation within the body 10 and is provided with a forwardly extending stub axle 1'7 and a'rearwa'rdly extending tub axle 17. The axle 1'7 is supported for rotation in a split bearing 18 of the body 19. The a'xle 17 is supported by a bushing 19 of a cylinder 22, said bushing having a bearing surface 19 .for support and rotation in a split bearing 1 of the body 10. The axle 17 is preferably formed with a noncircular configuration to transmit rotation of the drum 16 to the bushing 19 which is preferably formed with a noncircular'outer surface forward of the surface 19 to transmit rotation of the bushing to the cylinder 22. The forward end of the cylinder 22. is provided with a spring urged stub axle 20 of reduced diameter for support and rotation in a split bearing 21 of the body it).

The cylinder 22 is made to resemble the cartridge cylinder of an actual six-gun and is provided with six longitudinal openings 4-5, the purpose of which will hereinafter be described.

The anvil drum to is preferably approximately cylindrical in shape. The face of the striking hammer is made to mate approximately with the anvil face 23 as shown or may be approximately fiat. Six tapered spikes 24 are positioned in equally spaced relation around the circumference of the anvil drum 16 at distances tomatch and permit engagement of a row of apertures 25 in a perforated strip 26 of caps 26 being fed onto the anvil drum l6 from'a magazine or mounting chamber'lS during operation of the gun. The spikes 24 engage the apertures 25 in the perforated strip 26, and comprise a feeding means for feeding caps 26' to a position onto the anvil face 23 to be percussively exploded t-y the hammer.

Six equally spaced indexing pins 27 are attached to the outer end 28 of the anvil drum 16. The indexing pins 27 are positioned to cooperate with a pawl 29 so that explosive charges of the perforated strip of caps 26 are precisely positioned for firing by the hammer 31. This operation is additionally described below.

The hammer 31 is provided with a head 32 having a striking face 39 thereon dimensioned to fit between two adjacent spikes 24 and to substantially cover and approximately mate with this surface area 23 of the anvil drum 16. The face 3%) is preferably provided with longitudinal grooves of serrations 38 to provide passageways to direct smoke and flash resulting from an explosion alongrthe longitudinal axis of the body Til. Integral with the head 32 of the hammer is arcuate portion 33 having a spur portion 34 formed thereon. The spur portion 34 is shaped for gripping by a thumb of the hand holding the revolver for the purpose of cocking the hammer. The spur portion 34 also is shaped to resemble the corresponding portion of the hammer of an actual revolver and is adapted for fanning with the palm of the free hand which is not employed in gripping the handle 11 of the gun.

The hammer 31 is pivotaily mounted at the lower end of the arcuate portion 33, preferably in bearings formed in the side of the gun body it (not shown). An axle 37 is preferably integral with the hammer 31 and has mounted in it a torsion spring 38 maintained in a loaded state by having one end 39 thereof bearing against a pin 41 fixed on one side of the gun body and the other end 42 hearing against a projection 43 formed on the hammer 31. The torsion in loaded spring 38 is such that after the hammer 31 is pulled or pushed back into cocked position, when released it will snap sharply forward and strike the head 32 thereof against an explosive cap charge positioned centrally between spikes 2 on the anvil drum 16.

Referring to Figure 4, it will be noted that because of the relationship between the anvil face 23 and the hammer striking face 30, an angular, wedge-shaped gap 40 will be formed between said face at the instant of contact with an explosive charge of the cap strip. As the face 3d approaches the face 23 during the completion of the travel of the hammer 331, the gap lli is closed to squeeze the smoke and flash resulting from the explosion from the gap into an opening 45 of the cylinder 22. The grooves 3 3' additionally direct the smoke and flash into the opening 45 which is then conducted through the hollow barrel 12 and discharged from the forward end thereof for added realism and safety.

The anvil drum to may optionally be provided with longitudinal grooves or serrations indicated in broken lines 16 in Figure 4, parallel, or inclined, relative to the hammer surface Bil to further facilitate conduction of smoke and flash in the direction of the barrel via the openings 45.

A lower arcuate portion 4-4 also is integral with the hammer 31. it extends downward and then curves around upward to an end portion shown at 46. The end portion 46 of the arcuate portion 44 of the hammer also is provided with a solid pin 48. Mounted loosely with elongated apertures 47 on pins 48 is the pawl 29 provided with a clevis portion This clevis portion straddles the hammer portion 46, as best shown in Figure 2. A trigger pawl 72 pivots on pin 73 which is integral with hammer 31 and located on the lower area of arcuate portion 33. A torsion spring 51 is loosely mounted on a projection 53 which is an integral part of hammer 31. Torsion spring 51 is maintained in a loaded condition by having one of its ends 52 hearing against a projection 74 integral with trigger pawl 72, and having the other end 54 positioned in a notch 56 formed in the pawl 29.

The lower end 54 of the spring 51 provides rotational force of the pawl 29 against the anvil face 2 3 and a pre- 6 load bias for the slot 47 against the pin 48. The upper end 52 of the spring 51 provides a restoring force for the trigger pawl 72 as will be further described.

When the hammer 31 is moved into a cocked position. the lower arcuate portion 44 thereof and pin 48 will be turned in a clockwise direction about axle 37, as seen in Figure 2. This will cause the pawl 29 to move upwardly relative to the rearward side 28 of the anvil drum 16, as shown in phantom at 29 in Figure 3. The torsion spring 51 causes the pawl 29 to engage the rearward end 28 of the anvil drum 16. Thus, the pawl 29 is caused to slide upward and downward reciprocally against the rearward end 28 of the anvil drum as the hammer 31 is cocked and fired, respectively.

The pawl 29 is provided with an actuation engagement portion 57 and a stop engagement portion 53. The shape and dimensions of the portions 57 and 58 are made such in respect to the positioning and spacing of pins 27, so that when the pawl 29 is urged upwardly by cocking the hammer 31, actuation portion 57 of the pawl 29 strikes a pin 27 immediately thereabove, and imparts a turning or spinning movement about axle 17 to the anvil drum i6. Shortly thereafter the stop portion 58 is struck by a diametrically opposite pin 27 descending from immediately thereabove, and the turning or spinning of the anvil drum 16 is stopped, as shown in Fig. 3. The orientation of the pins 27 and the portion 58 is such that the stopping of the drum 16 occurs with a portion 23 between spikes 24- at the highest point across the top of the anvil drum 16, and in position for being struck by the downwardly descending face 30 of hammer head 32.

It will be observed that by the use of this arrangement of pawl 29 and pins 27, indexing can be made very accurate even with generous manufacturing tolerances. The anvil pins 27 are integral or attached to the anvil drum 16. The tolerances here do not add up because the pins and the anvil drum are in one piece. Similarly, the portions 57 and 53 of the pawl 29 are on one piece. Here again the tolerances do not add up and can be made generous without sacrificing precision. These portions can, of course, be located quite accurately in a one-piece pawl construction of this type.

In prior art gun mechanism, on the other hand, indexing parts often are made in many separate pieces and manufacturing tolerances add up to the extent that precision and accuracy of the gun mechanism are sacrificed. A good deal of mis-firing results in prior art mechanism as a consequence of this disadvantage inherein therein. About 40 percent of mis-fires is not uncommon. In the gun mechanism of my invention, on the other hand, misfiring is reduced to a minimum because the design and construction thereof prevents the tolerances from adding up, as described above.

It will be seen that because of the design for prevention of accumulating tolerances built into the gun mechanism of my invention, the hammer 31 can be rapidly fanned in the manner employed by the gun fighters of the old West. Mis-firing is reduced to a minimum because of the positive and precise actuation and stopping ofthe anvil drum 16 by the portions 57 and 53, respectively, of the pawl 29. The hammer 31 can be fanned as rapidly as is humanly possible and the anvil drum is repetitively actuated and stopped by portions 57 and 58 respectively, with a cap charge precisely positioned in a horizontal plane and centrally of the uppermost portion 23 of anvil drum 16.

The gun can be fired in normal operation by use of a trigger 59. The trigger 59 is pivotally mounted on a pin 61 which is an integral part of trigger 59. Also mounted on pin 61 is a torsion spring 62 maintained in a loaded condition by having one of its ends 63 held against a pin 64 fixed to the side of the gun body 10, and the other end 66 positioned against a projection 67 formed on the trigger 59. The trigger 59 contains a lower finger portion 68 shaped for convenient operation with the index finger of the hand gripping the handle 11, and projecting into the trigger guard 14 in conventional manner.

An upper portion 69 of the trigger 59 extends upwardly and has its upper end in engagement with portion '71 of the trigger pawl '72. It Will be seen that when the trigger is pulled backward at finger portion 68, the trigger will pivot around axle 61 and cause the upper portion 69 of the trigger to pivot in a counter-clockwise direction resulting in-drawing the hammer backward into a cocked position. This will cause the upper end of the trigger 59 to urge the pawl 72 at portion 71, and consequently the pin 73 integral with the hammer 31 in a clockwise direction, resulting in drawing the vupper portion of the hammer 31 including hammer head 32, backward into a cocked position. As the trigger is drawn backward progressively at finger portion 68 and the upper portion 69 is urged forward progressively, the upper portion of hammer 31 will be urged backward progressively until the upper end of the trigger 59 slips off the end 71 of trigger pawl The resulting increased torsion produced in torsion spring 38 by cocking the hammer 31 will cause the hammer to snap forward sharply when released and fire the positioned cap charge on anvil drum 16, as described above. After the actuating backward pressure on finger portion 68 of trigger 59 is released, the increased torsion in spring as will then cause the upper end of the upper trigger portion 69 to press backwardly against the trigger pawl 72 mounted on pin 73 of hammer 31 and cause the trigger pawl 72 to move upwardly against the end of torsion spring 51. As the hammer 31 returns to its original position, trigger pawl 71 passes upward over the upper end of trigger portion 69, allowing the trigger to move back into the position shown in Figure 2, below the trigger pawl 72 ready for another actuation by the backward urging of finger portion 68, as just described above.

The cap firing mechanism of my invention has been described above as applied to a cap firing revolver resembling a six-gun. It will be understood however, that the mechanism of my invention can be embodied in other types of revolvers, pistols or guns aswell as various cap firing mechanisms adapted for various purposes.
