REVOLVER.

Specification of Letters Patent.

Patented July 16, 1907.

Application filed February 14, 1907. Serial No. 357,346.

' in Revolvers, of which the following is a specification.

My invention has relation to revolvers; and in such connection it relates more particularly to the construc tion and arrangement of springs for the same.

The principal objects of my invention are, first, to

provide a revolverwith a trigger-spring which is supported by the frame and trigger so as to relieve all pressure from the guard heretofore serving as a support for the same, and thus preventing inaction of the triggerspring whenever the guard becomes displaced; second, to provide a trigger-spring, which through wear, or due to improper length, does not bind or become disconnect ed from the trigger, as is the case in the leaf springs heretofore used, thus preventing the trigger-spring from becoming inoperative, after a limited use; third, to provide for such purpose, the revolver with a coiled spring which offers an even resistance to the movement of the trigger, and to so connect the spring with the trigger as to prevent side friction or jamming between the trigger and the bolt serving as' a fulcral point, for the same,

fourth, to provide the revolver with a guard, which merely serves as cover for the trigger and which, when removed, permits of free access to the trigger-spring,-

and a trial of the operation of the spring prior to the placing of the guard in position; fifth, to provide the revolver with a wire spring for returning the ejectorcam to its proper position, which, consisting wholly of tempered wire, is more uniform in its action, and will not readily break; and sixth, to provide the revolver with a grooved ejector-cam which maintains the free end of the ejector-spring in its proper position thereon.

'lhenature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which Figure l. is a view, illustrating partly in side elevation and partly in section, a revolver, showing the arrangement and connection of a wire spring with the frame and trigger, a wire spring with the grooved ejector-cam and a main spring with the handle and hammer, as well as a slot arranged in the trigger and hammer for receiving and guiding the ends of the respective springs to permit of free movement of the hammer and trigger by engaging the same at a point below their fulcral points and centrally thereto, all embodying main fea tures of my said invention; and Figs. 2, 3 and 4 are de tail view, illustrating perspectively, the trigger, ejectorcam and hammer.

Referring to the drawings 5, represents the frame of the revolver which supports the barrel 6, cylinder 7, guard 8, and ejector-cam 9. To the frame 5, by means of a bolt 11, is pivotally secured the trigger 10, which is provided with a slot 12, a rranged centrally in the trigger 10, and at a rightangle to the bolt 11, thereof.

ondbolt 13, extendingthrough the slot 12, thereof, and serving to support the hooked arm 15, of a coiledtriggerspring 14, the other bent end forming an eye 16, engaging a post 17, secured to the frame 5.

tic, and thus more durable, as the pressure exerted on the spring is evenly distributed over the coiled portion of the same. i

By supporting the spring by the frame 5, and trigger, 10, the spring is visible, thus permitting a trial of the operation of the spring 10, before placing. the guard8, in position. Moreover, the guard 8, serving ,merely as a cover for the spring-14, does in no way interfere with the proper operation of the spring, when becoming displaced, By permitting the arm 15, of Ethe spring 14, to engage the trigger 10, at a point located directly in a central vertical plane thereof, a binding of thetrigger on its supporting bolt 11, is overcome, which binding produces rapid wear be- ,tween the trigger and bolt; and moreover, produces a; sudden increase infriction, when the trigger is manually operated. Such increase in friction effectually interferes with taking and maintaining a steadyaim. By the connection of the spring 14, with j the trigger l0, and by its outline, the resistance offered to the movement of the trigger 10, by the spring 14, is an even one, whichin no way interferes with the maintenance of a steady aim. Furthermore, by disengaging the eye ]6, of the spring 14, the hooked arm 15, thereof, can readily be brought out of engagement with the trigger bolt 13, and just as quickly brought into re-engagement therewith, and with the post 17.

,The eye 16, of the spring 14, by being held under tension in engagement with the post 17, also serves to support and to hold the eye portion 19, of the ejectorcam spring 18, in position on the post 17. The cam spring 18, consists likewise of tempered steel wire of uniform thickness. which insures uniformity in the resistance offered, and will thus not readily break. In order to hold the free upper end of the cam spring 18, in proper or operative position on the cam 9, the same is provided with a groove or depression 20, as shown in Figs. 1 and 3. The spring 18, being thusheld in position at its upper and lower ends, will effect at all times, the return of the ejector-cam 9, to its proper operative position. The arrangement and connection of the cam spring 18, with the post 17, also permits of a ready insertion and removal of the same after the guard 8, is disengaged from the frame 5, and the eye 16, of the trigger-spring 14, removed from the post 17.

Be low the bolt, 11, the trigger 10, is provided with a sec- The triggerspring 10, is made of aneven tempered steel wire of uni form thickness, which wire renders the same more clas The hammer spring 21, used to actuate the hammer 22, in its construction and outline, does not differ materially from the spring shown and described in an application for a patent granted to me, under date of February 26th, 1907, Ser. No. 327,995. However, its connection with the hammer 22, as will be hereinafter described, eliminates any possible binding, and thus rapid wear between the hammer and its supporting bolt 23, or of increased resistance to movement due to such binding, Such increase and uneve n resistance on the part of the hammer 22, will naturally prevent the even action of the trigger 10, due to the spring 14, since the hammer, by means of the lifter 26, is connected with the trigger 10. To guard against any possibility of uneven action on the part of the hammer 22, the same at its lower end is provided with a slot 24, arranged in a central vertical plane of the same. Through the hammer 22, and the slot 24, thereof, is passed below the bolt 23, a second bolt 25, which is arranged in advance of the bolt 23 and serves as a fulcral point for the hook-shaped end 29, of the arm 28, of the hammer spring 21. By engaging the hammer 22, directly in a vertical central plane and below and in advance of its iulcral point 23, the spring 21, will outside of decreasing the pressure of the spring when the hammer is raised by moving the arm 28 thereof, towards the bolt 23, and increasing this pressure when the hammer descends by moving the arm away from the bolt 23, prevent any undue friction between the hammer and bolt, When the hammer is lifted against the tension of the spring 21, by the lifter 26, actuated by the trigger 10. The spring 21, at the end opposite the arm 28, terminates in a bent or eye portion 30, engaging a post 31, which is secured to the frame 5, and forming a portion of the handle 32, of the same.

Having thus described the nature and objects of my invention, what I claim as new and desire to'secure by Letters Patent is:
