EDWARD SABINE RENWICK, OF MILLBURN, NEW JERSEY.
SPECIFICATION forming part of Letters Patent No. 792,077, dated. June 13, 1905.
Application filed June 20, 1904. Serial No. 213,208.
To all whom it may concern:
Be it known that I, EDWARD SABINE REN- WIGK, of Millburn, in the county of Essex and State of New Jersey, have made an invention of certain new and useful Improvements in Pistols; and I declare that the following, in connection with the accompanying drawings, is a full, clear, and exact description and specification of the same.
This invention consists of improvements upon the invention set forth in the United States patent granted to me, No. 628,356, dated July 4, 1899. The invention of said Patent No. 628,356 consisted of certain combinations of devices of a revolver with a finger-guard to protect the index-finger of the user from the flame and clippings of lead that may escape from the seam between the front end of the breech-cylinder and the adjacent end of the barrel of the firearm. In the forms described in that patent the finger-guard was arranged at the side of the cylinder about horizontally opposite the stud or pivot (upon which the cylinder turns) when the pistol is held with the central plane of the handle in a vertical position. Some users of the firearm have objected to that form of the invention on the ground that the finger-guard, if applied as represented in the drawings of the said patent, is so far to the right hand of the axial line of the barrel that if the index-finger be inadvertently pressed strongly against the finger-guard the muzzle of the barrel is diverted to side opposite the finger, and consequently the bullet is in such case diverted to the left hand of the object fired at.
The object of the present invention is to obviate the said objection and also to improve the construction of the finger-guard and its connection with the firearm.
The present invention therefore consists of a new construction of the finger-guard and of its combination and arrangement with certain members of the firearm, as set forth in the specification of claims at the close of this description.
The accompanying drawings represent several forms in which I have embodied the invention.
Figure 1 represents a side view of a revolver-pistol embodying the entire invention. Fig. 2 represents a top view of the same. Fig. 3 represents a cross-section of the same at the line w m of Fig. 1. Fig. 4 represents a side view of parts of a firearm with the finger-guard attached to a portion of it in the rear of the cylinder. Fig. 5 represents a cross-section of the same at the line as m of Fig. 4:. Fig. 6 represents a side view of the finger-guard of Fig. 5 detached from the firearm. Fig. 7 represents a rear end View of the finger-guard of Figs. 5 and 6. Fig. 8 represents a cross-section of the finger-guard forged in one piece with the lower bar of the lock-frame. Fig. 9 represents a cross-section of the finger-guard attached to the lock-frame of a repeating-pistol of the Luger variety in which cartridges are automatically introduced in succession into a single breech-chamber.
The lock-frame A of the revolver-pistol represented in said drawings, the chambered revolving cylinder B, and the barrel 0 may be constructed and combined with each other in any one of the systems in common use, and therefore do not need a detailed description. In order that the present invention may be embodied in the revolver repeating-pistol represented in Figs. 1, 2, and 3, a finger-guard D is so constructed that it may be arranged in proximity to the bar G of the frame of the handle or stock at the lower right-hand quarter of the breech-cylinder, as shown in the said figures. This finger-guard is preferably constructed of curved or gutter form, with a shank F, by which it may be secured to the pistol with its convex side next to the cylinder B, as shown in Fig. 3. The forward end of this finger-guard overlaps the seam E between the forward end of the cylinder B and the rear end of the barrel 0, so that when the index-finger of the user is extended along the finger-guard it is effectually protected from the flame or lead clippings that may be ejected from the said seam. The finger-guard so arranged in proximity to the bar Gr of the stock- 9 frame or lock-frame constitutes a guide for the index-finger when the pistol is fired, so that the barrel is naturally pointed at the object, and the finger-guard in this combination and arrangement has the advantage over the arrangements of finger-guard represented in said earlier patent, No. 658,233, that it is so much nearer the vertical plane of the axis of the barrel that the aim of the pistol is not likely to be diverted by the pressure of the finger upon the finger-guard. Moreover, as the guard in this new arrangement may considerably overlap the upper side of the finger it tends to steady the aim at the object and determines the position of the index-finger in firing. The finger-guard thus described when combined with a revolver-pistol has its body E skewed relatively to its shank F, as seen more particularly in Figs. 3 and 7, the dotted lines 8 s and o 0) representing, respectively, thedirectionof the mean plane of the finger guard and the direction of the plane of the shank thereof in the pistols represented at Figs. 1 and 4. The finger-guard withthe skewed shank is an improvement upon the finger-guard represented in said earlier patent, No. 658,233, in which the mean plane of the finger-guard is substantially parallel with the mean plane of its shank. The new fingerguard thus described may be made as a sepa rate article of manufacture, adapted to being secured to repeating-pistols already in use by means of screws, (or other means,) as represented in Figs. 1 and 4:. In place of securing it at its rear end to the frame of the pistol its shank may be at its lower edge and may be secured to the side or in the upper surface of the lower bar G of the lock-frame, as represented in section at Fig. 3, or the finger-guard may be forged in one piece with the lower bar of the handle-frame, as represented at H, Fig. 8.
The finger-guard (represented in Figs. 1, 2, and 3) is extended in the rear of the breech chamber or cylinder, which construction affords a firmer grasp of the hand upon the firearm, which with some users is advantageous.v The finger-guard also may be combined with the lock frame of a self loading repeatingi pistol, (without a cylinder,) such as the Luger pistol. tion is represented in Fig. 9, in which the finger-guard is arranged, as it is in the revolver previously described, in close proximity to the bar G of the lock-frame, which connects the barrel with the handle. When so combined, the finger-guard determines the position of the index-finger in firing the pistol and tends to steady the aim at the object, as well as directing it.
I specify as my invention- 1. A finger-guard for revolving firearms constructed to extend longitudinally of the same at the lower right-hand quarter of the breech-chamber to protect the position of the index-finger of the operator substantially as described, and direct the aim.
2. The'combination of the frame and breechcylinder of a revolver-firearm with the fingerguard arranged to project at the lower righthand quarter of said cylinder substantially as described.
3. The pistol frame or stock havinga guide for the index-finger of the right hand of the operator extending in the same general direction as the barrel, and arranged at the lower righthand quarter of the breech chamber substantially as described. a 4. A finger-guard for a revolving firearm constructed with the plane of its shank skewed to the mean plane of its body substantially as before set forth.
5. A finger-guard for pistols extending longitudinally of the same in proximity to the bar of the frame which connects the barrel with the handle of the pistol substantially as before set forth.
In testimony whereof I have hereto signed my name this 7th day of June, A. D. 1904:. EDWVARD SABINE RENWICK. Witnesses:
