SPECIFICATION forming part of Letters Patent No. 657,918, dated September 18, 1900. Application filed May 26, 1900. Serial No. 18,145. (No model.)

To aZZ whom it may concern.-

Be it known that we, JAMES LLOYD Cor- PING and GEORGE DYSON Tanner, subjects of the Queen of Great Britain, residing at Dashwood House, New Broad street, London, England, have invented new and useful Improvements in Breech-Loading Small-Arms, of which the following is a specification.

Our invention relates tobreech-loading small-arms of the kind wherein the cartridges are fed into the breech-chamber from a magazine, the invention being applicable to firearms wherein the several operations of the gun are automatically efiected by the recoil or performed by hand.

The object of the said invention is to provide means whereby the cartridge-holder, which is inserted into the magazine or which forms the magazine, shall be automatically ejected from the gun directly the last cartridge is delivered from the same into the breech and, if desired, to arrange means whereby the number of cartridges which the magazine contains shall be indicated.

In the accompanying drawings we have shown a suitable arrangement for carrying out the invention In the said drawings, Figure 1 is a sectional side elevation of a magazinepistol having the improvements applied thereto. Figs. 2 and 3 are a sectional plan and a side elevation of a detail; and Fig. a is a sectional side elevation thereof, drawn to a larger scale.

a is the barrel of the pistol, b the frame carrying the same, and c the handle or grip, which is made hollow to take the cartridgemagazine d in the usual manner.

e is the breech bolt or block, and f the trigger, of the pistol.

In connection with the aperture through which the cartridges 9 g pass from the magazine (Z to the breech-chamber is an arm h, pivoted upon a spindle or pin 1., mounted in the frame I) and carrying a ratchet-wheel i, the said-arm it being provided with a springpawl h arranged to engage with the teeth of the said ratchet-wheel The free end of the arm normally projects into the path of the cartridges g g in such a manner that as each cartridge is moved past the same it impinges upon the arm and causes it to oscillate, so that through the medium of the pawl 71 a certain amount of rotation is imparted to the ratchet-wheel i, as shown clearly in Fig. i.

h is a spring which returns the arm h into the path of the cartridges after each movement, and h is a detent for preventing the ratchet-wheel t turning back after it has been set forward and for rotating the said wheel when a new magazine is inserted, as hereinafter described.

The cartridge holder or magazine (1 is held in position in the grip c by a bolt or the like j, which is normally held in engagement with a notch or slot (1' in the magazine by a spring it. Now to withdraw the bolt when the magazine is empty we provide,in connection with the ratchet-wheel, a cam Z, which rotates intermittently with the said ratchet-wheel and when the latter has completed'arevolution.

impinges against one end of a lever m, which is pivoted at m to the frame 7), and the other. end of which engages in a slotj' in the boltj in such a manner as to withdraw the bolt from the notch 01' against the action of the spring 70, so that the magazine is released and left free to fall out under the action of gravity or to be forced out either by the springn, which pushes the cartridges into the breech-chamber, or bythe special spring n, which is put into tension when the magazine is inserted into the grip, the said spring being secured at one end to the fixed pin n and at the other. end to the slide n carrying a projection 12;, against which the top of the magazine bears when pushed into the grip so as to stretch the spring.

To indicate the number of cartridges which remain in the weapon, we arrange upon the spindle h, carrying the ratchet wheel, a pointer 0 outside the frame I), the said pointer moving in front of a dial fitted in the frame and numbered in such a manner that as the pointer moves forward with the ratchet-wheel as each cartridge is delivered into the breechchamber it stops opposite a figure upon the dial, indicatingthe number of cartridges re-- maining in the'weapon. In the pistol shown in the drawings the dial is numbered to correspond to a magazine capable of holding eeaeis seven cartridges, and the bolt j, which re tains the magazine (Z in the. gun, is so arranged in relation to the ratchet-wheel r1 that the magazine d will be ejected immediately the last cartridge is fed into the breech'chamher and before it is fired, this arrangement being of especial advantage in firearms which. operaie under the action of the recoil, the discharge of the magazine indicating to the person using the firearm that one cartridge only remains, whereby ifa freshly-charged holder or magazine is inserted into the gun before the last cartridge is fired it Will not be necessary to insert the first cartridge from the recharged magazine into the barrel. by operating the breech-bolt by hand, as is sometimes the case when the last cartridge is discharged before a freshly-charged magazine is inserted. To enable the pointer to he moved from the numeral 1 to the numeral 7 when a fresh cartridge-holder is inserted, the above-named detent is secured to the slide a so that it drops with the said slide when the emptied holder is ejected and is pushed up by. the insertion of the fresh holder, thus rotating the ratchet wheel 7 through a distance equal to the length of one tooth.

Although we have described and shown an arrangement wherein the mechanism for releasing the magazine is actuated by the movement of the cartridges, it will be obvious that the said mechanism can also be operated from any other suitable intermittensly-moving part of the pistol.

' Having now particularly described and. as-

certained the natureof our said invention and in what manner the same is to he performed, we declare that what we claim is 1. In breech-loading small-arms the combination with the cartridge-magazine, of means whereby the said magazine is automatically ejected when the last cartridge has been fed from the maeazino snbstantiall. as hereinheifers described.

2. in breech-loading small-arms the coznhi:

nation with the magazine, of a spring-bolt engaging a slot or notch in the magazine so as to hold it in position, and of means for Withdrawing; the bolt out of engagement with the magazine when the last cartridge has left the magazine, substantially as scribed.

in breech-loading smalharms the combination with the magazine, of a spring-bolt normally engaging a slot or notch in the 5. In breech-loading" small-arms the comhi-' nation with the magazine, of a pointer and a dial, of a ratchet-wheel in connection with the pointer, and of a pawl for actuating the ratchet-wheel, the said pawl being mounted upon an arm which normally extends into the path of the cartridges so as to be intermittently operated thereby substantially as, and for the purpose, hereinbefore described.
