To @ZZ whom it may concern: v

Be it known that I, HARRY ANDREWS, a subject of the Queen of Great Britain, resid,- ing at TNoolwich, London, in the county of Kent, England, have invented a newand usefullmprovemcnt in lrojectiles for Firearms, (for which I have obtained patents in Great Britain, No. 7,927, bearing date May 13, 1889; in France, No. 202,572, bearing date lDeceniber 13, 1889;' in Belgium, No.` 88,841, bearing date December 11, 1889; in Italy, No. 33,251, bearing date January 13, 1893;-in Spain, No. 10,327, bearing dateMarch 8, 1890, and in Austria Hungary, No. 1,087, bearing date January 3, 1890,) of which the following is a specification.

The object of my invention is to facilitate the use of miniatureammunition with magazine-rides, machine-guns and .other firearms;

Heretofore an apparatus for adapting firearms for use with miniature ammunition'comprised aV tubular'piece or block adapted to hold the miniature cartridge in its forward end and having at its rear end ahead orange corresponding in form and dimensions to that of the ordinary service-cartridge, a sliding pin being arranged Within and extending through the said tubular piece or block to communicate to the primer of the miniature cartridge the blow or impact of the firing-pin, hammer or striker of the firearm. The miniature cartridges for use with thisapparatus require to be specially formed at the rear end or'base to permit their attachment to the said tubular Apiece or block. By my invention I provide an.

apparatus of this kind or class which is simp ler in construction but more eicient than that described above. Moreover, by reason of the improved construction of my appara- .tus miniature Icartridges with ordinary rim bases, heads' or anges can be firmly secured therein. The said apparatus is, therefore, Well adapted for use in magazine or repeatingV firearms.

or service cartridge, and can be asreadily fed 5 5 from the hopper or .magazine into the cham ber of a gun.

My said invention, moreover, comprises other improvements hereinafter set forth.

In the accompanying drawings l have shown 6o how my said invention may be conveniently and advantageously carried into practice, of Which- A Figure 1 is a longitudinal central section of one form of my improved apparatus, the 65 miniature cartridge being shown in side elevation. Fig. 2 is a rear elevation of the said apparatus. Fig. 3 is a side elevation illustrat- Fig. 4 vis a side elevation illustrating a slight modification of 7o the said apparatus. Fig. 5 is a longitudinal central section showing another form or modication of my said apparatus. Fig. 6 shows a further modification of construction.

Similar letters refer to-correspondin g parts 7 5 throughout the several views.

A is an ordinary or service cartridge case or shell, which may with advantage be made of cartridge abutting against the internal shoul- 9o der of the shell A, as shown in Fig. l, so that the cartridge is retained firmly in position in the said shell.

C is the tubular block or plug, Which is inserted into the body of the shell A and iits 95 the same closely at each end, and Which is formed of Wood, metal or other suitable material or of Wood strengthened with metal Where ment of the said pin in the block or plug C.`

f beenred and the apparatus extracted from withdrawal of the expanded empty shells This groove is so made as to permit the neceswhen worn out or damaged by repeated blows 'the sake of likeness, or

necessary. In the central hole C of the block or plug C is fitted to slide longitudinally the communicating pin or striker D.

In the apparatus shown in Figs. 1 to 3 the said communicating pin or striker D is retainedA in the said block or plug C by means of 'a set-screw E, the inner extremity of which enters a circumferential groove D in the pin D.l

sary longitudinal or endwise play or move-l F is a head securedupon the rear extremity of the communicating pin or 'striker D by means of screw-threads or it may be secured thereon in any other suitable manner that will permit its ready removal from the said pin or striker when desired; or the said head may be separate from the pin or striker and so held in the block or plug C that it can move longitudinally therein and will bear against the rear end of the said pin or striker.v The removable head F receives the impact of the striker, hammer or tiring-pin of the gun, and

therefrom may be readily removed and replaced by a new one, thus obviating the necessity for replacing the entire pin or striker. It is obvious, however, that I can if. desired form the head solidly upon the pin or striker. A recess or cavity C2 is formed in the block or plug C to receive the said head F and permit the necessary movement thereof when struck by the striker, hammer or firing-pin of the gun. f 1 l G is a split ring which 'is arranged in a circumferential groove C3 in the block or plug C, and which, when the said block or plug is inserted into the shell A, will be slightly compressed and will retain the said block or plug 'in position in the said shell, while permitting its withdrawal therefrom when desired. The block or plug C may be formed as shown for it may be of any other suitable shape.

The removal of the block or plug C and of the shell of the miniature cartridge B from the shell A after the said miniature cartridge has the firearm can be readily eected. For this purpose the said shell of the miniature cartridge is pushed inward or backward,together with the block or plug C, suiciently to enable the latter to be withdrawn from the rearend of the shell A. The said miniature shell may then be easily removed and another miniature cartridge insertedin its place. The block or plug being reinserted in the shellA, the apparatus is again ready for use. I

I som etirnes form one or more slits in the forward end or neck of the shell A, as at A2, Fig. 4, to facilitate the insertion of the miniature cartridges therein, and more particularly the therefrom.

For quick-firing and other guns of larger caliber I prefer to construct my apparatus as which is screwed into the recess or cavity C2 inthe said plug and is provided with an inter. nal flange H, serving as a stop or abutment for the collar F' of the head F. As this stop or abutment retains the pin or striker D in the block or plug C, I am enabled to dispense wsg the set-screw E, above mentioned. The sai sleeve H can be readily withdrawn to permit the removal and replacing of the head F. By this arrangement the manufacture of the block or plug C is simpliiied, as the saidA plug can'be cast with a suitable core, and it will then only be necessary to bore the same out at each end and form the screw-threads in the cavity C2. It will be seen that by reason of the construction of my apparatus in the manner above described I am enabled to dispense with a spring for eiecting the backward or return movement of the pin or striker D after it has been driven forward to iire the miniature cartridge.

The backward or return movementlof the said 7 pin or striker in my apparatus can be eected by hand after the removal of the block or plug from the shell A,or Vit will be effected in the operation of reinserting the said block or plug in the said shell behind the miniature cartridge. l

hammer or firing-pin of the gun is greater than is required toV fire the miniature cartridge I can introduce a spiral or other spring,

in combination with the pin or striker D, to partially counteract this force and thus diminish the force of the blow communicated through the said pin or strikerD to the primer of the miniature cartridge. i

Instead of the split ring hereinbefore .described 'I can employ any othersuitablespring or springs for retaining the block or plug C in the shell A. For instance, I sometimes form a spring vby making one or morey slits A2, Fig. 6, in rear end or'body of the cartridge-shell A, and contracting the said shell at this end, as shown; or I can employ other suitable means. for holding the afore' said -block or plug iirmly in position in the body of the shell A, while `permitting its withdrawal therefrom when desired. It is obvious, moreover, that I can somewhat iur ther modify the construction of my improved app/aratus without departing from the nature of my said invention. For instance, instead roo I'Io

of an ordinary or service cartridge-shell bored i out at its rearend, I can, if desired, employ a steel or other tube so formed as to accurately t the chamber of the firearm.

, My improved-.apparatus can be more easily and' cheaply manufactured than those heretofore used.4 Moreover, the apparatus may be so constructed that, together with the miniature cartridge, it will be of the same weight and externally of the same form as the ordinary service-cartridge, thus permitting (pr-facilitating the feeding of the said ap paratus from the hopper or magazine into the chamber of a gun. Having now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be performed, what I desire to claim isl. A. tubular piece, adapted tohold a cartridge composed'of.. a shell A, provided with an internal' tubular block C, carrying the communicating pin or striker D, and having a split ring G, surroundingl said block C, at

its front end, substantially as and for the purpose set forth.
