BREAKDOWN BREECH-LOADING GUN.

SPECIFICATION forming part of Letters Patent No. 495,639, dated April 18, 1893.

Application filed August 18, 1892.

To all whom it may concern.-

Be it known that I, GUSTAV ADOLF SACHS, a subject of the Emperor of Germany, and a resident of Eugene, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Firearms, of which the following is a specification.

This invention relates to certain new and useful improvements on my patent on breechloading fire-arms, No. 353,432, issued to me on the 30th day of November, 1886.

The object or my invention is to provide a new and improved lock to facilitate the detaching of the barrel from the stock, to provide means for automatically cooking the gun, to provide an automat-ically-operating safetydevice and an indicator to show whether the gun is cocked or not.

The invention also consists in the construction and combination of parts and details which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a top-view of the breech-part of my improved breech-loading fire-arm. Fig. 2 is a side-view of the parts, showing the breech open. Fig. 3 is a vertical longitudinal sectional view showing the breech closed. Fig. 4 is a planview of the stock, parts being shown in section on the line 4 4, Fig. 3. Fig. 5 is a vertical transverse-sectional view, on line 5 5, Fig. 3. Fig. 6 is a top-view of the trigger-plate, parts being in section. Fig. 7 is an inner sideview of one lock-plate. Fig. 8 is a view of the inner side of the fore-arm. Fig. 9 is a vertical longitudinal sectional View of the same on the line 9 9, Fig. 8. Fig. 10 is an inner sideview of the cocking-slide. Fig. 11 is a sideview of the same.

Similar letters of reference indicate corresponding parts.

The barrels A are provided a short distance in advance of the breech-end on the under side with 3. lug A provided with a notch a in its front end and at the breech-end with a hook-lug A having a notch a at the rear end. A recess a is formed between said lugs. Some distance in advance of the lug A, the barrels are provided on the under side with a lug A provided in its front end with a notch a as shown in dotted lines in Fig. 9. The fore-arm B which is made of wood has a plate B in- Serial No. 443,389. (No model.)

sorted in its inner surface and said plate is provided with a transversepiece B having a curved recess B that fits on the rounded hinge-parts C at the front end of the breechblock 0 so as to turn on the same and on the hinge pin 0 at the front of said breech-block. At the bottom of the recess B a shoulder Z1 is formed for the purpose as will be set forth hereinafter.

In a recess at the front end of the plate B a sliding latch-pin B is arranged that is acted upon the helical spring B arranged between the front end of said recess and the head of said latch-pin, so as to press the pointed end of said latch-pin through the front end of the slot b, so as to adapt said latch-pin to engage the recess or notch a in the front end of the lug A of the barrel. To fasten said fore-arm to the barrel, it is only necessary to place its front end upon the rounded hinge-end O of the breech-block C and then press the said fire-arm against the under sides of the barrels. The latch pin B then snaps into the notch a of the lug A of the barrel and locks the fore arm to the barrel. The fore-arm can easily be removed, all that is necessary being to pull its front end outward, when the beveled edges of the notch a acting 011 the point of the pin B force said pin into the recess against the action of the spring B.

To the under side of the breech-block a cocking-slide D is arranged which consists of a plate having a longitudinal guide-slot D for a guide-pin and is provided atits rear end with a slot I) and with a flange D, at each side of said slot D which flanges project into the lock chamber. At the front end said cocking-slide is provided with a flange D on which the edge b of the rear end of the plate B in the fore-arm can act. When the barrels are swung into open position,as shownin Fig. 2, said edge if acts on the flange D of the cocking-slide and moves the same in the direction toward the rear, causing the flanges D to act on the hammers E which are mounted on a pin E in the lock-chamber, which hammers are pivoted on arms T projecting from the rear end of the lock-chamber. Said hammers are each provided with two shoulders e and e. A bent spring F is provided for each hammer E, and of each spring one end rests against the shoulder e of a hammer and the other end rests against the shoulder f of a trigger-sear F mounted on a pin F, also held on the arms T, the front end of which trigger-sear engages a shoulder e of a cone sponding hammer. Each trigger-sear is provided at its rear end with an inwardly-projecting arm F which enters a notch g of the corresponding trigger G, which triggers also swing on the pin F.

Each trigger is provided at its inner end with a lug G which can abut against the safety-bolt II projecting through the longitudinal slot 1 of the breech-tail I into the lock-chamber, which safety-bolt is fastened to and projects'from the plate or safety-slide H that is mounted on the outer surface of the breech-tail I, and is provided at its lower end with a series of notches h on its under side, which notches are engaged by pointed ends of a locking or safety-pin J arranged in a suitable aperture in the stock and guided in the same, which safety-pin is pressed outward by the helical spring J. The outer surface of the lower end of the safety-slide H is serrated, as is shown at h in Fig. l, to prevent the finger from slipping while manipulating the same. The word Safe is engraved or etched on the upper surface of the breech-tail in such a manner that when the safety-bolt H is in such position that the lugs G of the triggers abut against the same, the upper end of the safety-slide H does not cover the word Safe, and when the safety-slide II is moved up so as to bring the safety bolt l-I out of the path of the lugs G of the triggers G the word Safe will be covered.

Above the upper end of each hammer F an indicator-pin K is arranged in an opening of the breech-tail, which pins are pressed inward by springs K surrounding them. Said pins K are provided at the inner and outer ends with heads, the outer heads fitting into recesses in the breech-tail. When the gun is cocked the upper ends of the hammers E press on the inner heads of the indicator-pins K and press said pins outward, so that their upper heads project from the upper surface of the breech-tail, thus showing that one or both hammers are cocked. As soon as the gun is fired or uncooked, the springs K draw the indicator-pins inward, so that marksmen can at all times tell which hammeris cocked.

The firing-pins L are provided at their inner ends with heads L that are guided in recesses M, of the lock-plates M and by recesses f the breech-block and on said heads L the hammers E can act. A stirrup N is hinged at the ends of its shanks to the safetybolt H and its closed front end is arranged between the two hammers and adjacent to the lever 0 which passes through a slot in the barrel locking belt]? that enters the notch (t in the lug A at the breech-end of the barrels. A spring S secured to the under side of the breech-tail bears against one end of said locking-bolt P and presses the same toward the front.

To open the breech, the lever O is pulled toward the stock W, so as to disengage the front beveled end of the bolt P from the notch a of the lug A and the lever 0 while being moved toward the rear presses upon the front cross-piece of the stirrup N and presses the same toward the rear. As this stirrup is connected to the safety-bolt H it also presses the same and safety-slide 11 toward the rear, thereby exposing the word Safe to view. By this movement of the safety-block H to the rear, it is brought in such a position as to rest upon the upper end of the lugs G of the triggers, thereby preventing the triggers from being manipulated- Before the gun can be fired, the safety-slide H mustbe moved toward the front again so as to cover the word Safe on the top breech-tail and to bring the lower end of the safety-block H in front of the lugs G. The gun can now be fired. To open it again for the next charge, it is necessary to pull the lever 0 back again, whereby 1n the manner described, the safety-bolt II is agaln brought into position above the lugs G of the triggers. The spring J automatically locks the safety-slide in the different positions. The breech-block C has two recesses m and m for receiving the lugs A and A of the barrels respectively. Said breech-block has a lug 0 containing a screw 19, the beveled lower end of which can act on the front end of the lug A and when the barrel is swung in closed position presses the same firmly against the abutment s of said breech-block. A screw 10 in the abutment s also has a beveled lower end and rests on the upper surface of the locking-bolt P and serves to adjust the same to bring it in proper position in the slot of the abutment through which it passes, thus permitting of adjusting said locking-bolt P to be in proper position for engaging the notch a of the lug A V is the trigger-plate.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a breech-loading fire-arm, the combination with hinged barrels and pivoted trig gers, of a sliding barrel-locking bolt, a pivoted lever for operating said bolt, a sliding plate mounted on the breech-tail, which sliding plate has a post against which the triggers can strike, a spring for locking said sliding plate in different positions and means for shifting said sliding plate from the lever for operating the barrel-locking bolt, substantially as set forth.

2. In a breech-loading fire-arm, the combination with pivoted barrels, of a sliding barrel-locking belt, a pivoted lever for operating said bolt, a sliding plate on the breech-tail, a post projecting from said sliding plate, a stirrup hinged to said post and having its front closed end adjacent to the lever for operating the barrel-locking bolt, and pivoted triggers that can strike against the post projectingfrom the sliding plate, substantially as set forth.
