IMPROVEMENT BREECH-LOADING FIRE-ARMS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, SvEN RYDBEOK, of Red Wing, in the county of Goodhue and State of Minnesota, have invented a new and valuable Improvement in Breech-loading Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description of the construction audoperation-of the same. reference being bad to the annexed drawing makinga part" of this specification, and to the letters .and figuresof reference marked thereon.

- Figure 1 of the drawing. is a central vertical section of my invention, when fired.

Figure 2 is a similar section, showing the positionof the parts when the breech-piece is drawn down after firing.

Figures 3, 4, 5, (i, 7 8, and 9 are details. 7

My invention relates to fire-arms; and consists in,

the construction and novel arrangement of devices designed to form a simple, durable, and efficientbreechloader.

The parts of my invention are few in number and simple in their construction and mode of-operation.

and

B the lock-plate.

0 represents the guard-plate.

D is thebreech piece, sliding at right angles to the axis of the barrel, and operated by means of the guardlever E. It is'pelforated in an upward and forward direction to receive the firing-pin a, which is kept from falling out by the end of the set-screw b operating in the depression 0 between the head 0 and the shoulder h.

'it is operated.

In drawing the slide down, this lug m works against the pin a, which is inserted through the walls of the cleft. At the same time the extreme end of the lug an engages with the hammer and carries it downward with the breech-piece until it is caught by the sear s.

The letter A of the drawing designates the barrel,

cured to the upper tang of the lock-plate.

\Vhen liberated from the sear by means of the trigv ger l, the main-spring forces the rear part of the hamrner down, thereby causing the forward portion to strike upward against the head of the firing-pin.

a designates the sear-spring, which is secured to the guard-plate.

The forward end of the guard-plate is forked and slotted, to embrace the pins 0, by which it is secured in position.

I designates a stout spring, having a shoulder, 0', designed to press'upon the side of the lever-guard E, thereby producing friction, except when the end of the lever is up against the guard-plate or drum, down to its lowest position.

The gun having been discharged, the lever E is drawn down, thereby opening the rear of the chamber, throwing out the shell of the cartridge and setting the hammer.

A fresh cartridge having been inserted, the lever is drawn up, returning the slide to its place, when the piece is ready to be discharged.

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

1. In combination with the sliding breech-piece 1), provided with the firing-pin b, and having its upper and forward corner beveled, the extractor z, having the under. portion of its rear end correspondingly beveled, and the combined hammer and tumbler H, arranged to strike upwardly against the end 0 of the firing-pin,

substantially as shown and described.

2. In combination with the guard-lever E, the friction-spring P, havinglug r, as specified.

3. In combination with the sliding breech-piece 1), combined hammer and tumbler H, extractor z, and friction-bar P, the guard-lever E, having the lugs m and it, when constructed and arranged to operate in the manner and for the purposes shown and described.

,In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
