Description
UNITED S'rAns Ericao JACQUES P. PIERI, OF GHISONI, GORSICA, ASSIGNOR TO WILLIAM SMITH,
' OF LONDON, ENGLAND.
-IMPROYEMENT IN BREECH-ITOADING FIRE-ARMS.
Speeitication forming part of Letters Patent No. 166,138, dated July 27, 1575; applicationiiled April 30, 1875. I
To all whom it may concern:
Be it known that I, J AcQUEs PHILIPPE PrERI, of Ghisoni, Corsica, a resident of London, England, have invented Improvements in Breech-Loading Fire-Arms, of which the following is a specification:
My said invention relates to breech-loading firearms which have at the rear of the barrel a chamber, wherein is fitted a sliding barrel or bolt carrying the tiring mechanism, including the trigger, which lies in a groove in the said bolt, and projects from the rear of the same. A firing-pin is tted inside the said bolt, and is released by depressing the said trigger, and driven forward by a spiral spring.` The said bolt has at its forward end a head, which is so attached to the said bolt that it moves endwise therewith, but allows the said bolt to turn without turning the head, and this head is provided with a device for extracting the empty cartridge-shells. The breechbolt is moved in its chamber to open and close the breech by a handle projecting at the side of the said bolt.
My invention is illustrated in the accompanying drawing, which I will now proceed to describe.
Figure l is a plan or top view of the breech of a rilie constructed according to my improvements. Fig. 2 is a longitudinal section on the line x rv, Fig. l. Fig. 3 is a plan of a portion of the breech-bolt. Fig. 3 shows the end of the same with the trigger and firing-pin. Figs. 4 and 5 illustrate a safety device forming part of my improved mechanism.
Like letters indicate the same parts throughout the drawing.
A is the stock, and B the barrel. c is the breech-bolt, and b is the head ol' the same. c is the liring-pin. d is the trigger, and e is the extractor. This trigger is a iat spring or elastic piece, tted in a groove in the bolt, and may be readily removed and replaced when necessary. It has a projection, d', for holding the ring-pin c. The trigger d, when in position for ring, presents a fiat surface above the stock, as in Fig. l, and is pressed downward by the thumb to release the iiringpin. The piece 6*, below the stqck, supports the hand in depressing the trigger d. The head b, at the forward end of the breech-bolt, is formed with a groove, b1, in which enters the point ot' a stop-screw, b3, that projects through the guide-piece al of the aforesaid bolt a, and the head b also has a helicoidal surface, b2, which acts 'on a shoulder, c', of the ring-pin or rod c, in cooking the arm. The handle or lever a3 of the bolt a and the guide-piece al are made solidly, or in one piece with the cylindrical portion of the said bolt, but the end of the said guide-piece projects beyond the forward end ofthe bolt, as shown. At the under side ot' the breech I arrange a safety device, which keeps the bolt from turning or moving endwise in its chamber when the bolthandle is turned upward, or in the position for withdrawing the said bolt; and, when the bolt is in this position, the depression of the trigger will not actuate or release the firingpin. This safety device consists of a small spring pin or rod, f, which is fitted to move up and down, and turn in ahole formed through the under side of the breech-chamber, as clearly shown in Fig. 2. The said pin has a shoulder or stud, f1, which is so arranged in relation to inclines f2j`3 on the under side of the breech-shoe that, when the said pin is turned upon the incline f2, it will project up through the bottom of the breech-,chamber into a hole or cavity in the bolt a, and hold the same inimovably, but when it is desired to release the said bolt, the spring-pin fis turned partially around in its hole, and its shoulder f1 then comes upon the incline f3, which is not so deep as the incline f2, and the pin fis then held down below and clear of the bolt.
The extractor of this improved arm is a iiat I www...
'nation of the breech-bolt a, havingl the trigger d and screw b3, the head b, having groove b1 and inclined surface b2, and the firing-pin o,
having the shoulder c', substantially as described and shown. l
4. The safety device f, arranged and operating'in combination with the bolt a, as hereL in set forth.
5. In a breech-loading lire-arm, the combination, with the breech-bolt a and head b, of the extractor e, constructed and arranged substantially as described and shown.
