Description
Patented Dec. 7, 1937 UNITED STATES PATENT OFFICE MACHINE PROJECTOR Charles J. Manville, Indianapolis, Ind.
Application March 11, 1935, Serial No. 10,347
13 Claims.
This invention relates to a machine projector adapted principally for the projection or firing of tear gas shells, although applicable to firing other types of shells, such as shells embodying shot, slugs and the like.
It is the purpose of the invention to provide a projector which will discharge a plurality of shells containing gas, shot or slugs in rapid succession, and is principally adapted for use in handlng mobs, strikes, jail deliveries and other similar unlawful gatherings involving violence and destruction.
Briefly, the invention consists in providing a circular rotatable magazine containing up to twenty-four or more shells which, through the means of cams and springs, is caused to rotate to automatically and successively bring the shell chambers into firing position upon each firing operation.
One feature of the invention resides in the provision of an individual firing pin for each chamber or shell, as distinguished from the usual structures embodying only a single firing pin for all chambers or shells. By reason of this arrangement, in event a pin jambs or breaks. or a shell fails to fire, all other shells will continue to be fired by their respective operative pins, since the automatic recocking and firing mechanism will be unaffected thereby. This s to overcome the danger of rendering the' entire firing operation ineffective at a cruc al moment by damage to the pin. Thus, by reason of this invention, in a projector having twenty-four chambers and twentyfour pins, should one pin' or shell become ineffective, there would still be twenty-three shells fired. On the other hand, a projector employing a single pin or recoil for recocking and rejection of a shell would become ineffective as to all the twenty- 40 four shells, none of which would fire.
Other features of the invention reside in the arrangement of the cocking cam and the chamber registering cam which makes the projector automatic and positive in its action. Thus. the operation of the trigger to fire a cartridge automatically and rapidly recocks the firing pin plunger upon completion of its firing operation, preparatory to the next firing operation. The register cam is also operated thereby to lock the rotatable magazine in position with a chamber in registry with the muzzle at the instant of firing, and releasing the chamber to permit partial rotation to register the next chamber with the muzzle immediately upon completion of the firing oporation. Thus the projector is automatic in its operation and operates as the trigger is pulled.
as positively and rapidly Still a further feature of the invention resides in the locking device to prevent manual rotation or winding of the magazine until the firing mechanism is on safety, thus eliminating any danger of premature or accidental firing during the setting of the magazine.
In addition to the above, the trigger and hammer are so associated as to permit the firing of only one shell for each trigger operation. This permits accurate and positive determination and control of the firing operation.
The above and other features of the invention will be set forth in the specification and claims.
The full nature of the invention will be understood from the accompanying drawing and the following description and claims:

showing the magazine in its cocked or initial firing position.
Fig. 6 is the same as Figs. 3 and 4 showing a modified form.
In the drawing there is illustrated a machine projector comprising a containing a plurality spaced about the periphery thereof.
drum-like magazine 10 of shell chambers ll Removably associated with the magazine on one side thereof there is a cam housing or drum l2.
The magazine is rotatably supported upon a centrally disposed stud I; mounted upon a bracket l5 which carries a forward handle l6 and a muzzle l1.
Removably associated therewith, in addition to the drum, there is a cover plate l8 integral with the drum and a housing I9 containing the fire mechanism. Depending from the housing through suitable openin rear face of the magazine.
vided with a plurality gs 'or perforations in the Said cam disc is proof peripherally formed ratchet teeth 23 which act as registering cams, one
for each chamber II.
On the rear face of the disc there are provided a plurality of tooth-like cam members 24 extending laterally from the sur face and housed by the drum l2. The cam members 24 are slightly spaced apart to permit a firing pin 25 to be positioned therebetween, there being provided one firing pin for each chamber II. tatably mounted upon the stud l4 in which there is anchored one end of a winding spring 2'7. The other end of said spring is anchored to a block 28 secured to the drum [2.
The control mechanism comprises principally a firing hammer 29 which is in the form of a cylindrical plunger slidably mounted in the housing I9. The rear end of said plunger is connected to a rod 33 terminating in the safety device head 3|. The rod 30 is slidable in a closure plug 32 which is provided with a diametrically positioned groove 33 in which the ends of the pins 34 are adapted to engage when the mechanism is on safety. In firing position, the head 3| is turned so that the pins 34 are diametrically opposed to the grooves 33 and the slots in the plug 32 permit the pins 34 to slide therethrough when the head 3| is turned from the safety position illustrated in Fig. 4 to the firing position illustrated in Figs. 2 and 3. Surrounding the rod 30 there is a firing spring 35 which is compressed under'spring tension in the safety or cocked position shown in Figs. 2 and 4. Thus, upon the hammer 29 being released, the spring 35 forces it forwardly under spring tension to a position where a head 36 in the form of aroller strikes the firing pin 25 and causes it to fire a shell in the chamber H in the usual manner, the firing position thereof being illustrated in Fig. 3. 1
To release the hammer 29 there is pivotally mounted therein a spring pressed latch 31 normally held in latched position by springs 38 against a latching finger 38, said finger being pivoted to the housing l9 and pressed into engagement with the latch under tension of a spring 40. A finger trigger 4| is pivoted to the housing and normally held in forward position by a spring 42. Said trigger carries a plunger '43 pivoted thereon in position to engage the end of the latch 31 when latched through operation of the trigger to release said latch against the tension of the spring 38 from the finger 39. Upon release of said latch, the spring 35 becomes effective to operate the hammer 29 for firing a shell.
For periodically registering a new chamber II with the muzzle I I after each successive shot, there is fulcrumed within the housing l9 at 44 a locking arm 45 having its lower edge provided with oppositely disposed cam surfaces 46 and 41. The surface 4'! is in the path of a pin 48 on the hammer 29. while the cam surface 46 is in the path of the end of the hammer. Adjacent the cam 46 there is a projection which extends into the path of movement of the registering cams or ratchet teeth as illustrated in Fig. 5. The cam is normally maintained in locking position with respect to the registering cams by a spring 49.
When the hammer is retracted, as shown in Figs. 2 and 4, the pin 48 engages the cam surface 4! and, coupled with the pressure exerted by the spring 49, maintains the projection in engagementwith the face of one of the registering cams to hold its corresponding chamber H in registry with the muzzle. Said chamber is thus held locked in registering position until the hammer 013i ates the firing pin as shown in Fig. 3. Such forward movement of the hammer engages the Said cam disc is provided with a hub 26 rocam surface 46 while the pin 48 on the hammer releases the cam surface 41, thus forcing the forward end of the lever 45 upwardly so that the projection is lifted out of engagement with the registered cam to permit rotation of the magazine immediately upon firing to bring the next succeeding chamber into firing position.
In operation, it may first be noted that the projector comprises two removable sections, one section including the magazine muzzle, bracket I5 and handle I6, while the other section includes the cam disc, spring housing l2, firing mechanism housing l9, handle 20 and plate l8. Said parts are removably connected in operation by the thumb screws 50. To load the magazine,
the thumb screws 50 are loosened and the two sections are slipped apart, the pins 22 disengaging the openings in the rear face of the magazine, whereupon the shells may be inserted in the usual manner within their respective chambers I I from the rear. Upon the magazine being thus loaded, the sections are again connected as illustrated in Fig. 2 and the screws 50 tightened in place.
The projector is normally on safety as illustrated in Fig. 4, wherein the hammer is retracted with the spring 35 compressed and the pins'34 engaging the groove 33 in the plug 32. To fire the projector, the head 3| is rotated a quarter revolution to free the pins 34 from the grooves 33 to allow them to register with the slots or openings provided therefor in the plug 32.
The projector is fired by pulling the trigger 4| which releases the latch 31 permitting the hammer to be forced forwardly by the spring 35. The head 36 of the hammer is caused to'impact upon the firing pin 25 which will fire the shell in the usual manner. Simultaneously therewith, the forward end of the hammer will engage the cam surface 46 of the lever 45 to throw the projecting end thereof upwardly against the tension of the spring 49 to disengage the registry cam 23. This allows the spring 31 to take effect to rotate the cam disc 2| as illustrated in Fig. 5 in the clockwise direction. Such movement of the cam disc causes one of the cocking cams 25 to engage the roller 36 of the hammer and force it rearwardly to cocking position thereby permitting the latch 31 to engage the latch finger 39 by reason of the tension of the springs 38. Thus the hammer is again cocked under tension of the spring 35.
Upon the cocking action of the hammer, the cam surface 46 of the lever 45 is released to permit the spring 49 to cause the projecting end to follow down the inclined surface of the next fol lowing registry cam 23. The pin.48 is at the same time brought into engagement with the cam surface 41 of said lever to more positively force its projecting end downwardly so as to arrest further clockwise movement of the cam disc when the face of the next following cam 23 engages thereagainst. In this position, the next succeeding chamber is brought into registry with the muzzle. Thereupon the projector is ready for the next firing operation. Thus, it will be noted that the firing action of the hammer simultaneously fires and releases the registry cam while the spring 21 immediately and automatically partially rotates the magazine to bring the next chamber into position, which rotation recocks the hammer.
If one of the firing pins becomes broken or obstructed or the corresponding shell fails to fire, the automatic magazine action and recocking will be unaffected so that the following shell will be fired by its individual firing pin irrespective of the ineffectiveness of the preceding one.
After all the chambers have been emptied, the spring 21 will have been unwound, whereupon the sections of the projector are separated, the magazine reloaded and the spring wound by manually rotating the magazine in counterclockwise direction.
In order'to prevent manual rotation of the magazine for winding the springll, when the firing mechanism is in firing position, the pin 48 is so positioned on the hammer 29 as to remain in engagement with the cam surface 41 to hold the projection 33 in looking engagement with the registry cams 23. Upon the firing mechanism being moved to safety position, as illustrated in Fig. 4, wherein the pins 34 engage in the grooves 33, the pin 48 is moved rearwardly and free of the cam surface 41, as illustrated in Fig. 4,,so as to release the lever 45 and permit it to ratchet over the registry cams 23 and to wind the spring.
In the modified form illustrated in Fig. 6, the finger 39 is eliminated and in place thereof there is provided a pin I39 for latching engagement by the trigger latch 31. In addition thereto, there is provided a plunger I40 having a head HI and pressed by the spring I42 to normally retain it in retracted position wth the head bearing against the trigger. The cam disc is provided with a plurality of perforations I43 spaced thereabout so that there will be one perforation for each firing chamber. This arrangement is' particularly adapted for use in firing a shotgun shell where it is desirous that there be no movement of the magazine until after completion of the discharge through the muzzle. Thus, upon pulling the trigger, the plunger I40 is forced into one of the perforations I43 which locks the magazine against movement until the trigger is released.
