To aZS whom it may concern.'

Be it known that I, GREGORY GERDOM, of West Troy, in thecounty of Albanycnd State of New York, have invented certain new and useful Improvements in Breech-Losding Ord-- nance, of which the following is n specilice'- tion. Y

This invention relates to improvements on cartridge-shell ejeetors for breech-loading ordnance, and it especially relates to improveniente on the ejectingdevice shown in are herein referred 'to end torin'pert ot' thisV specification.

in snid drawings, Figure l is s. horizontal longitudinal section of e portion of the breech of s breech-lending cannon, carrier-ring, and ejector; seid carrier-ring being shown in position for holding the breech-block in place.

to close the breech of the cannon, with the ejector at itsinnermcst position; Fig. 2, alike section, with the carrier-ring turned back to cnrrythe breech-block out of the breech of cannon, and the ejector moved to its outermost position. Fig. 3 is n transverse section of Fig. 1 ntthe line X X. Fig. 4 is n vertical section of part of the breech of the cannon and the cnrrienring, et the line Y Y on Fig. 3, with the. ejector shown in front elevation. Figs. 5 and 6 are respectively an end eleve.-

-tion and s side elevetion'of the ejector detnched from the cannon; and Figs. 7 and 8 are respectively n detached plan view and nn end elevation ol the lever for moving the ejector.

As represented in the drawings, A desig- 1 naiss e. portion of the breech of e breechloading cannon made substantially es described in Letters Patent No. 451,241 granted to me April 28, 1891.

. vi3 designates the csrrierring which carries the breech-block for closing 'the breech of the cannon, seid breech-block being omitted from the illustrations; scid cerrier-ring-with the :rceptions hercinnternoted--heingsubstnnl form an onset hinge for it, but, unlike the,

carrier-ring shove referred to, the knuckle of said erm, es et E, iserrsnged eccentricelly to the center of the pin C for e. purpose herein-4 after explained. Thearm D hss s recess, F, formed et its inner end, so as to partially inclose' the pin C and form 'e shoulder, G, at the inner end of the knuckle E.

,Il designates an ejector-operating lever which is arranged in the recess F and is provided with s slctted9pening, l, through which the pin C is passedg" the minor diameter of seid opening should correspond to the dinin-v eter of the'pin C, so that the lever II can have partiel rotation thereon,but the major diameter of seid? opening should 'be suihcient to allow said lever to have n slight endwise movement on the pin C; and it'will be observed that by this construction provision is made to allow the lever il to partake of e combined swinging and endwise movement. The lever H is provided with n, shoulder or shoulders, J, which bear against the knuckle E in such manner that, when the carrier-ring B is swung into the position shown in Fig. 2, the eccentricity of said knuckle will have pushed Asaid lever inwardly toward the center line of the cannon, toward which point the eccentric knuckle will steadily move said leverv from its initial position, as shown in Fig. l, to its final position, es shown in Fig. 2. The inner end of the lever H is made wedge-shaped, es et K, so that when seid lever is in the position shown in Fig. 1, the inner face of seid end will coincide with the line of the inner end of the slot through the side of the breech. The face L, of the'lever H, isl

practically radial from the center of the pin C, and it isso arranged that, when the cerrier-ring B has completed about one half of its movement, the shoulder G will take against the fece Lend eec'i: epsrtialfrotation of the lever H on the pin C.

M designates the cartridge-shell ejector.

loo

which is provided with guides, N, arranged at opposite edges and fitted to slide in longitudinal holes, O, formed in the breech of the cannon; said ejector is provided with a segmental lip, P, that is arranged to engage nder the peripheral iiange on the outer end of a cartridge-shell, at the opposite side of the inner face of said ejector, an angle-seat, Q, is formed to correspond tothe wedge-shaped end K of the ejector-lever 4H, so that normally said lever-end will lie in the space formed by said angle-seat, so that, by the first forward movement of the lever H; an initial i Amovement of the ejector M toward the rearmost end of the breech A will be begun by said ieve'r Wedging the ejector rearwardly, then, by a continued swinging movement 0f `the carrier-ring B, the lever H will acquire a corresponding swinging movement-*as hereinbefore described-of sufficient velocity to eject a cartridge-shell fromthe bore of the cannon. When the breech-block is being restored to its place in the breech A, it will push l the ejectorM inwardly into theposition shown in Fig. 1. A tap-screw, R, is inserted in the outerend of one of the holes O, for the purpose of restricting the rearward movement of the ejector M.

My invention operates in the following manner: The cartridgebeing insertedin the breech Aof the cannon, with the peripheral flange of the cartridge-shell, bearing against the outer face of the segmental lip P of the ejector M,

Q as the cartridge-is pushed forward, either by hand or by the breech-block, into the bore of the cannon, the peripheral rim of' the cartridgeshell will continue in the same relation to the lip P after the breech-block is in place to close the opening in the breech of' the can-v non. To eject the cartridge, or the cartridgesheil after the cartridge has beenred, the carrier-ring B is swung from the position shown in Fig. 1 into the positioii shownin Fig.2; at the beginningof this swinging movement of the carrier-ring the lever H will :be pushed toward the center line of the bore of the cannon, whereby the wedge-shzp'ed end of said lever will be intruded farther under the ejector M and impel the latter slowly toward the open breech of the cannon, and this moderate movement of the ejector will continue until the shoulders J take against the face L ofthe lever Hand then said lever will have a swinging movement imparted to it, the. impetus of said movement will be sufoient to eject the cartridge-shell from the open breech of the cannon, the ejectment being made in a positive manner. In this construction the use of springs, and other delicate mechanism, that are liable to be broken or otherwise injured, is entirely dispensed with and all the movements are positive in their character. j

What I claim as-my invention, and desire to secure by Letters Patent, is-

1. In a breech-loading cannon, the combination o; a' carrier-ring provided with a hingearm having a-recess near its inner end; said recess terminating with a shoulder that is fitted to take against and impart a swinging movement to an ejector-operating lever; the convex surface of the inner end of said hinge` arm being eccentric to the center of the pivot on which said carrier-ring swings, a pivot or hinge-pin for said carrier-ring, an ejectoroperating lever having a nnb provided with a slotted opening through which said hingepin passes; said lever being adapted to acquire a combined sliding andv swinging movement, and an ejector operated bysaid lever and fitted to slide in a direction that is par# allel to the center line of the bore of the cannon, as and for the purpose herein specified.

2. In a breech-loading cannon, the combination, with a cartridge-ejector, N, provided with an angle-seat, Q, as herein set forth, of

an operating-lever, H, arranged to acquire a. combined Asliding and swinging movement ni provided with a wedge-shaped end, K,

.iitted to take against said angle-seat; whereby said ejector will primarily be wedged from its position at the inner end of the breech opening, and then--by the swinging movement of said operatinglever-forcibly moved toward the outer end of said breech opening,

as and for the purpose herein specified,

GREGORY GERDOM. Witnesses:
