Be it known that I, FRANK D., GRANGER, a citizen 'ofthe United States, residing in the. city,'county, and State of New York,-havej inyented certainnew and useful Improvements in Locks for .Firearms, otwhich' the followin g is atoll, clear, and e'iact description.-

My; invention relates to improvements in trigger mechanism for guns, and'espec'ially tomechanism by which a doublebarrel gun may be operated by means of a single-trigger; 7 The object ofimyinventioli i's to', produce a simple, safe, andreliable mechanism by which guns having more than one barrel may be op erated by asingle trigger, to produce-a'saiety catchby means of which thetrig'ger -me'c ha'nism may be lockedso'thattthe gun cannot be accidentally fired, toprovide anindicatin g deyice which will alwaysindfc'ate which barrel i is tobe exploded, and to firing the desired barrel.

To this end provide'means .for

bracket and the other end to the 'pin. The pin B extends downward-through thehollow brackeigand on the iower end of the pin is 1 mounted looselythe firing-disk 0, which has on its end surface as distinguished from its 1 eripheryandheanthe edge a series of reguy,inventiongconsists in"1 c ertain novel features and combinations of parts,

otwhich are all in the same direction, and the teeth are adapted toaiiternately raise'the' sears Dand. release the hammers as the disk rotates horizontally. It wili e seen byref: erence toFj'g, 3, that the sens-s are/placed in relation to, vthese teeth thatthesears will teeth on the disk, cheer the 'ther'of e se s will be raised every time the disk is'moved a 'tenth' of a revolution. The numberoE-tee'th desired number may be used,

To illustrate the construction or the mechlnected witha simple -form of hammer and tumbler, but it is obvioris that they maybe connected with any of the common forms in the us'ualc ay. As-.shown,rthe hammers 'D? on which are shoulders d-audfdflwhich are f,which are connectedlthe'rewith, and which re secured-1 in the lock-case, the front ends ot thesearsgbeing held in engagement with the tumblers by springsdfi "It will thus be seen thatthe ends of "the sears will engage 1 .fthe' shoulders on the tumblers and hold the sears are raised at their-rearends by the teeth C their'forward-endswill be lowered side-of the disk 0 are aIser-ies of ratchetteeth 0; which radiate from the central portion of the hub, there beingtwiceas many of these teeth as there are of the cam-teeth on the' upper surface of the disk, and the object .of these teeth isito engage the trigger-pawl so that when the pawl is pushed forward it will reVolvethedisk.

The upper whichis pivoted thereto, and which extends forward and upward through a slot h in the guide 'H,.which is, supported on the inner onthe disk, however, is not materiahas any .anism I have shown the searsf-D and D con lady-spaced ch n-teeth 0, the inclined sides be alternately raised,'snd,'as therearejfive I engaged by the'forward ends of the scars, and the hammers are pressed forward by springs.

. 7 are formed into t unblers at their lower ends, I

portion of.the breech, and the forward end of the paw-l G'is held in engagement with'the ratchet-teeth of the disk by means of a curved spring h',-thc free end of which presses against the under side of the pawl-and the lower portion of which is secured to the guide II. It

will thus 'be seen that when the trigger is pulled to tire the gun the upper end of the trigger will be thrown forward,thus pushing the .pawl- G forward and causing it to turn the disk 0, and when the diskis turned one of the inclined cam-teeth will engage a sear 1) or-D, raise the scar, and fire the gun.

In Fig. 3, one of the scars Dis shown just aftervit has passed a tooth O, and the opposite scar D is in position to ascend the incline of anothertooth C, but if, for'any reason, it is desired to fire the'barrel, which will not normally be fired by a sear D,-D', the pin 13 may be pressed downward, thus carrying down the disk 0 with it, and this movement will cause the pawl G to swing on' its pivot or fulcrum, thus pushing the disk around one notch, so that by manipulating the pin the disk may be brought into a desired safetycatch secu red in the breech behind the pin B, which catch comprises a slide-block J, held to slide in the slot a of the breech and provided with a finger-piece j, to facilitate its adjtistment and a'depending arm J', secured to the block and terminating at its lower end in a'forward bend j, the bent end being adapted to enter one of the notches-c ofthe. disk 0, and it will be seenthat when the bent.

end of the arm is in engagement with the disk,

I the disk cannot be turned; When the gun v spring-pressed pins 7;, which project upward 1 is to be used, the safety catch may be pushed rearward,thus freeing the catch. An indicator isused in connection with the invention to show which barrel isabont to be exploded, and the indicator comprises two through thebreech of the gun. Supporting arms- K are provided onboth sifdes of the hollow bracket a, each'termin'atirig in a box K,

containing a spring pressed-pin 7c. The pins It, will thus be held onopposite sides of the center, pin B, and the length s of the armsK .pins will align vertically with the teeth 07 on thefiring disk.. 3. The upper. cndsof the pins rest normally in sockets a in the top of e breech. The length of thepins issuch hat they will extend downward into the.path.of the teeth 0' on the disk, and the pinsare placed so that they will alternately engagelthe teeth, so" that when the disk is revolved firstwone pin will strike a tooth and then another, and the pins will movc up the inclined surfaces of the teeth ,scribed,

and be alternately projected above the top surface of'the breech, and those will thus indicate which barrel is about to he fired. If the right hand pin projects upward, it will show that the right-hand barrel is to be fired, and if the gunner wishes to fire theleft-hand barrel he pushes the pin B downward, thus causing the disk Otorevolve the dist-anceof one tooth in the manner described above, and

the firing-disk will thus be brought into positionto fire the left-hand barrel.

Having thus fully'described my invention,

I claim as new and desire tosecure by Letters,

the revolution of the disk, and a trigger connectedwith said disk for turning the same, substantially as described.
