y Beit known that LWILLIAM HALE DRIGGS,
i a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new andiuseful `Irriprovements in Firing Mechanism forGuns; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make'and use the same.
letters and numerals throughout the several ,l ss
My present invention relates to improvementsin firing apparatus for guns ,and it consists more especially in im rov'e'ments in apparatus forringy a gun eit er by'percussion or -by electricity, as may be preferred, using substantially the same principal parts with such additions as may-be necessary.
My invention will be understood by reference to the accompanyingdrawings, in which the same parts are indicated bythe same views.
Figure 1 shows a verticallongitudinal section through abreech -block of the v'wedge type, showing the adjacent parts ofthe gun.
This section-is taken along the broken line 1 1v of Fig. 3 and looking in the direction'of the arrows. Figure 2-shows a section along the line 2 2 of Fig. 1 and looking down. view ofthe gun, partly in section, along the broken line 3 3 of Fig. i and looking in the direction of the arrows. Fig. 4 shows a section along the line 4 4 of Fig. 3 and looking yin the direction -of the arrows.y Fig. 5 lshows a section along the line 5 5 of Fig. 3. Fig. 6
shows in side elevation the firing mechanism in the cocked position.
The gun and slide are shown in dotted lines and parts are omitted forthe sake of. clearness in' the drawings.
., 7 isa -plan view of thefiringfmec-hanism shown in Fig. 6; andFig.' 8 isla detail showing the firing-pin in the cocked position..
For convenience of reference lthe urely mechanicalparts will be designated by etters and the electrical connections andinsulating material will be indicated byy numerals.`
A represents the gun-body, B the breechblock,.and C an arm attached to the rocking slide, or cradle of the gun.' This arm Gais ,provided with overhanging flanges C2, adapted to receive Vthe ribs A2 on the guide-lugs A Fig. 3 is a rear at each side of the gun. The gun recoils inl the cradle, as is well knownin the art.
D represents the -cocking-lever, which is made in the form of a bell-crank pivoted on the pin E. This lever has a cooking-arm D and a head D2, which head engages in a slot in the firing-pin, as will be hereinafter described. The cooking-arm D is provided with a cooking-toe CZ, which engages the arm F on the sear F. lWhen the gun is cocked, the face f of this arm F engages the toe d', as shown in Fig. 6, but after the gun has been fired these arts are in the position shown in Fig. 1. T e breech of the gun is provided with a vertical slot a for the cooking-toe to travel up and down in as the block is raised or lowered and witha shoulder a to arrestl Vmechanism will be hereinafter described.
The head D2 of the cocking-lever D engages in the slot H0 in the firing-pin H. The rearl 'wall of ysaid slot is shown at H in Fig. 1.
This firing-pin H carries an. insulated head ing Y H2, terminatingin the pin-point h. 'This firing-pin is shouldered, as at h3, to engage the. ring L, (see Fig. 1,) and the breech-block is correspondingly shouldered, as at t3, to limit the forward travel of this ring in the block for purposes to be hereinafter described.
I represents the firing-spring, whose rear end L normally presses the head D2 back against lthe art H of the firing-pin, while .the front en of this spring 'i' presses against the ring L, as shown in Fig. 1. The spring is normally held under compression between theface g of the bushing G and the ring L. (See Fig. 1.)
The sear F carries an armF2 with alateral extension F3, to which is connectedone end of the spring M. The other end of the spring engagesthe hook m ofthe pin M', secured to the gun. Thus the tendency of this spring Mis to rock the sear, tendingv to cause the arm F to engage the shoulder a', (see Fig. .1,) but permitting the said arm to be pressed .downward by the cocking-toe d', as the breechblock descends. This spring also causes the extension F; on the arm F2 to engage the lug n on the rod N fast to or integral with the rod N, which rod carries at its forward end an arm N2 beneath which projects the trigger N3 just in front of the pistol grip P, which is car ried by the arm P integral with the late P2, fast to the arm C, secured to the cradle of the gun. By pulling 'on this trigger N3 the rod N will be slid backward, rocking the sea-r F against the action of the spring M and cans ing the face f of the cocking-arm F to pass clear of the cooking-toe d. This will release the cooking-lever, and the spring 1 will drive the firingrpin forward, firing the gun, as will be hereinafter described. The trigger-rod is normally pressed forward by a spring O.
The electrical connections are as follows: The current comes in the positive wire 1 (shown to the left of Fig. 3) and enters the binding-post 2 beneath the binding-screw 2, This binding-post is insulated from the arm C by means of the insulating-bushing 3.
From thebinding-post 2 the current entersl the conducting-plug 4 in the insulating-bushing 5, and thence passes to the conductingplunger 6, pressed forward by the spring 7 and thence passes to the conducting-plug 10. This plunger, plug, and spring are insulated, as at 8 and 9. From the plug 10i-he current passes to the conductor 11,insulated,as at 12, and thence to the screw 13, having a milled head 13, and this screw passes through the insulating material 15 and connects the conductor 11 with the conducting strip 14. This strip 14, with the conducting material 1.5, is dovetailed into the rear face of the breech of the gun, as shown in Fig. 5, and its outer face is iiush withthe face of the gun and is thus protected against likelihood of injury from careless operation of the gun or from small projectiles.` From the strip 14 the current passes to the spring 16, which is held in lace by the 'insulated screw 18 and is itse f insulated, as at 17. The arm 16a of this spring presses against the conducting-strip 14, and the opposite arm lb presses against the conducting-piece 19, which is insulated, as at 20, and is connected to the conductingblock 21 below the spring 22, which presses u ward the conducting-plunger 23. This p unger, spring, and block are insulated, as at 24. The plunger 23 contacts with the conducting-piece 25, insulated, as at 26, and this piece 25 is connected to the wire 27, insulated,
as at 28. This wire 27 and tsinsulatingcovering 28 are preferably mounted in a dovvetailed groove in the front of the lever D, which 'groove is then filled in with amalgam U. 2,) and thus this wire is held firmly mplace without likelihoodr of injury from ordinary causes. The upper end of this wire 27 is connected to a conducting-block 30,`"niountedin insulating material 31, carthe conducting-plug 35, as is also the firingpoint h. The head H2 of the firing-pin projects into a chamber a,0 in the nose of the breech-block, as shown in Fig. l and is sepaair-space and has at its base an insulatingwasher 36.
The operation of the device is as follows: j
Suppose it be desired to fire mechanically. The block is shown in Fig. 1 in the closed position with the firing mechanism in the position assumed after the gun has been fired.
8o rated from the walls of said chamber by an ,i
ln the operation of opening the breech for l reloading the toe d will slide down the slot a, pressing back the arm F against the action of the `coil-spring M, and as soon as this `toe passes this arm the arm F snaps back to the position engaging the shoulder a. The spring I will maintain the lever D and the firing-pin in the position shown in Fig. 1 so long as the breechblock is down. When the breech-block is raised again, the toe d will strike the arm F', and since the latter bears against the shouldera the further upwa'rd movement of'the breech-block will cock the firing mechanism, causing the face f to engage the toe d. When the mechanism is cocked, the ring L will be drawn back, compressing the spring I, as shown in Fig. 8. N ow if the arm F is released from engagement with the toe d', as by pulling on the trigger N3, the spring I will force the ring L forward, carrying with it the iiring-pin and the head of the sear, and this ring will con tinue its forward travel until it abuts against the shoulder b3 of the breech-block. At this time the ring L will be arrested; but the inertia of the firing-pin will cause the point h to fly farther forward, striking the primer and exploding the charge. The reaction of the spring on the scar-head will immediately return the firingin to the initial position, (shown in Fig; 1,l3thus drawing the point h back clear of thenose of the breech-block and preventing any injury to the same as the breech-block is raised or lowered and also drawing same clear of the primer. To fire electrically; the gun is automatically cocked by the closing of the breech-block, as already described with reference to the mechanical operation, or it may be cocked by hand by pulling the head D2 of the lever D back with a hook or an eye en aging in the hook cl2 until the toe d passes c ear of the arm F', when the face f will snap back to the cocked position, and'when the cooking-lever is released the spring I will cause the toe d to engage the face f. During the period of electric firing one pole of the source of electricity is maintained in electrical connection with the wire l, and the other pole is connected to some part of the gun-mount in the usual way. The circuit is completed from the wire 1 through the conductors 2, 4, 6, 10, 11, 13, 14, 16, 19, 21, 22, 23, 25, 27, so, 32, 34, and 35 to the point h. There is a break here which is closed vwhen the trigger is pulled, and the yfiring-pin flies forward under the action of the spring I, causing the point h to strike the Thus they primer and complete -the' circuit. same iiring mechanism may be used absolutely without change` to fire either by percussion or byelectricity, and Where combination primers are used, which are firedV either by percussion or electricity, one or the other of the agencies will accomplish the desired result.
hlt Will be obvious that the percussion apparatus may be used with the ordinary percussion-primer and the electric apparatus with the ordinary electric primer, while the apparatus is especially adapted for use with combination primers of the character just referred to.
' By having the conductors'14, 19, 25, and 27, with their insulating material, inlaid in the face of the correspondingv parts these conductors are not apt to be injured or affected in the ordinary handling of the gun or even should the gun be struck by small proj ectiles ,1 and they are not likely to get in the way in the operation of the gun, as happens 'where loose wires are used or where wires are attached to the parts of the gun and mount exterior to the surface thereof.
By having spring-plungers used in connection with the various contacts a good electric contact is secured, vwhich is especially desirable at points where there is apt to be a film of grease or water or other non-conducting-material.
It will be obvious that various modifications might be made in the herein-described -apparatus which could be used without departing from the spirit of my invention.
