PISTOL.

Specification of Letters Patent.

Patented Apr. 27,

To all 'whom t may concern:

Be it known that I, GEORGE S. LEWIS, a citizen of the United States, residing at Springfield, in the State of Massachusetts, have invented certain new and useful Improvernents in Pistols, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention has for its object to produce a lsingle-shot pistol, particularly adapted for target shooting, of simple, inexpensiveand rigid construction, the details ofimprovement being pointed out more particularly hereinafter, with reference to the accompanying drawings in which the invention is illustrated and in which- Figure 1 is a top view of the pistol closed.

Fig. 2 is a view of the same in vertical, longitudinal, central section.

Fig. 3 is a detail view of the barrel lock.

Fig. 4 is a view similar to Fig. 2, but showing the pistol broken.

Fig. 5 is a detail view in section on the lane indicated by the broken line 5-5 of ig. 2, looking in the direction of the arrows.

F ig. 6 is a detail view in section on the plane indicated by the broken line 6-6 of Fig. 4, looking in the direction of the arrows.

The pistol comprises two main parts, the frame a, chambered at a', as shown clearly in Figs. 2 and 4, with its grip pieces a2 secured by bolts as, and the barrel b secured in its sleeve or carrier b which is pivoted in the frame at b2. In the left-hand side of the frame, as shown in Figs. 1 and 3, in a recess a4 is pivoted on a screw c', a triangular barrel-latch c, provided with a milled surface c2 and normally thrown forward by a spring which is shown in part at c4, so that its nose c5 may engage a re cess b3 formed in the side of the barrel or its carrier b. To release the barrel, the latch is pulled back and when the barrel is again swung to a closed position it first presses the latch rearwardly and is then engaged by the latch in its closed position, the lower edge of the latch being curved on a slightly eccentric arc so that it shall engage the barrel with a cam-like action and so prevent possibility of movement of the barrel with respect to the frame wl pistol is closed.

In the under-side of the carrie: formed a dove-tailed groove b4, clearly in Figs. 4, 5 and 6, which i the extractor d formed at its rear at d', to enter the recess b in the the carrier and the end of the barn to engage roperly the cartridge, as clearly in ig. 2. A dog d2 is piv a slot a5 inthe forward end of the a, having a flat heel d3 to limit the i movement of the dogy when the I; opened by contact with the rear wa the slot, and having a nose d* whicl the barrel is closed, enters the slot Z dog is normally pressed forwarc' spring-pressed plunger d5 which is n in the frame, the forward movemen plunger being limited by a pin d". the pistol is closed the extractor d dog d2 occupy the positions shown 2, but when the pistol is broken t d4 of the dog, during the first parl breaking movement, engages the end of the extractor d and moves tively to the barrel, as shown in During the last part of the breakin ment of the barrel the dog Z2 ren rest by reason of the contact of its d3 with the rear wall a6 of the slot therefore its nose clears the forw` of the extractor d when the barrel the position shown in Fig. 4 so th a cartridge is fully inserted in the of the barrel and the extractor is forward its forward end acts aga inclined or cammed surface Z7 of d2 and thrusts the dog backward an ward out of the path of the e: Finally, when the barrel reaches tl position shown in Fig. 2, the forw of the extractor clears the nose of and permits it to be snapped up spring plunger d5 into the position s Fig. 2 in readiness to engage the f in the next breaking movement barrel.

It will be noted further that the f d is formed with an inclined or surface d8, best shown in Fig. 4, in the closing movement of the b: incline d8 strikes the frame at tf a7 and thereby the extractor is thr` ward and does not interfere with the closing movement of the barrel. The movement of the extractor in each direction is limited b a pin d, the end of which travels in a s t b5 in the under-side of the carrier b.

The hammer e is pivoted in the frame, is acted upon by a main spring e and plunger e2 and is controlled by a combined trigger and sear e3, acted upon by a springpressed plunger e4, all substantially as usual. The hammer is completely inclosed within the chamber a of the frame and is connected by a link e5 with the finger-piece e which is extended rearwardly through the frame so that the hammer can be cocked. The hammer acts as usual upon the firing pin f. The rear sight g, is shown in position in Figs. 1,2 and 4.

It will be understood that changes in the form and relation of parts may be made to suit di'erent conditions of use or the convenience of the manufacturer and that the invention is not limited to the precise construction shown and described herein except as pointed out in the claims.

I claim as my invention:

l. In a pistol, the combination of a frame, a barrel pivotally mounted on the frame, an extractor slidingr on the barrel, and a dog pivotally mounted on the frame and having a flat heel to coperate with the frame-to limit the swinging movement of the dog and provided with means for cooperation with the extractor in the forward movement of the extractor whereby the dog is moved out of the path of t to permit full forward moven the dog being free to engage t again when the closing move: barrel is completed.

2. In a pistol, the combinatioi a barrel pivotally mounted o1 an extractor sliding on'the barr pivotally mounted on the fra] ing a nose to engage the extr: inclined or cammed surface or above the nose to coperate tractor in its forward movexn the dog is swung rearwardly out of the path of the extract full forward movement thereof ing free to engage the extracto the closing movement. of the b pleted.

3. In a pistol, the combinatie a barrel pivotally mounted o an extractor sliding on the l pivotally mounted on the fra .ing a nose to engage the ext] pass out of engagement ther breaking movement of the l spring-pressed plunger carried and coperating with the do upward and return it to posit the extractor in the next br ment of the barrel.

This specification signed thi May, A. D. 1919.
