TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM SYDNEY SMOOT, of Washington, District of Columbia, have invented a. new and improved Cartridge-Extractor for Breech-Loading Fire-Arms, of which thc following is a full and exact description, reference being had to the accompanying drawing.

-The nature of my invention consists in providing for a breech-loading gun a cartridge-extractor which may be used either as n. positive retractor alone or as a. spring-ejector in addition thereto. As a positive retractor alone, it is of the essence of my invention to rotate the extractor on the axis of the breech-block, by which it is operated, and to make the block swing both in conjunction with, and also independently of, the extractor, to. inipart a suddenly acceleratedmovement, without restricting myself to It block opening upward or downward, or otherwise. As a spring-ejector in addition thereto, itis of the essence of my invention to impart a suddenly accelerated movementto the extractor, whether rotated on the axis of the breech-block or otherwise, as may be the more convenient for the play of the operatingspring. This spring, to perform its functions, may, as seen in the drawings, be made to react by passing the centre of the extractor, acting cndwise thereto, by link or other familiar attachment, or it-may be made to pass under or over the sume, and react by striking into a notch, or it may be madero act otherwise, so only that by its reaction the extractor is made to take on suddenly accelerated movement.

In order to enable others to make and use my invention, I proceed to describe mbre particularly its cnnstrnction and operation.

Figure 1 shows a. longitudinal section of the extractor, the spring, the cartridge-shell in the chamber, and

also the breech-block of a particular gun to which I have applied my invention, without meaning. to restrictmyself to this or any other particular pattern of breechloading arms. K

Figures 2 and 4 show projections of the working parts of the gun with the intervening side of the arm removed.

Figure 3 shows a front elevation of the breech-block and extractor, leaving out the spring c.

Through a slot in the breech-block A, and swinging on the axis thereof, b, I hang my extractor D, to rotate freely on this axis-pin b ofthe breech-block. Thearm of the extractor may be longer or shorter to suit convenience. On the extractorD I make a shoulder, n, to come in contact with the head of the cartridge-shell when D is rotated. Also on the extractor I make another shoulder, lo, to come in contact witli the face of A,

tio restrict or limit the play of D while/'acting independently of A, and moving in direction of its face. and I u leave for this independentplay of D an interval, as seen between. o and the face of A in fig. 2.

New, the gun having been fired, I open the block A, which carries with it D, Continuing the movement the shoulder n comes in contact with the rim of thc shell and retracts itby this positive movement. Meanwhile by this continued movement the spring c is brought to pass the centre, when it suddenly reacts and imparts its full force to accelerate the movement of D, which in turn transmits the ejeoting kick against the shell, and brings upto a stop by hitting its shoulder o against the face of A.

By inspection it will be seen that I may modify the relative positions of n. and a whenever the pattern of the arm to which I apply my invention makes it convenient; that'is to say, instead of the positions respectively of n and o, as shown, I make the distance between n and the face of A only suiiicient to admit the rim of the cartridge-head when'A is shut, and I enlarge the slot in the opposite face of A sufficiently to admit the arm of D a distance measured by the loose play I give to the extractor. When, nowI open A, it will move a distance equivalent to this same measure before `it begins to carry with it'the extractor D. Then it will gradually retract the shellas aforesaid. And when the spring comes to react, as aforesaid, it will impart the force and transmit the kiek as aforesaid. Only, now, n, 'instead of o, may be made to hit the face of A, or o may bel put in position to follow behind n, and bring up to a stop against the barrel of the gun instead of against the face'of A. y i

By inspection it will be further seen that as the greatest tension of-the spring c is when 'its position is at the point of passing the centre of the extractor, the shoulder o, in iig. 4, will hold A open, so that it will not of itself shut, and the arm of D, as shown in iig. 2, will hold A shut, so that it will not of itself open.

New, what I claim as my invention, and desire to secure by Letters Patent, is I claim a. cartridge-extractor, swinging loosely on a common centre with that of the'carricr or breechblock, when said extractor, after being gradually operated by swinging the said block, is made to take on by any means a. suddenly-accelerated movement to extract the shell, without accelerating the movement of the block itself by which the extractor is operated.
