SPECIFIGATION'forming part of Letters Patent'No. 543,652, dated July 30, 1895.
Application tiled May 9,1895. Serial No. 548,888. (No model.)
To all whom z5 may concern.'
Be it known that I, JOHN H. PALM, a citizen of the United States, residing at Chicago,
.in the county of Cook and State of Illinois,
have invented a new and useful Improvement lin Shell-Extractors for Firearms, of which the following is a specification.
The object of my improvement is to provide a device whereby the shell may be eX- tracted from the gun by hand-power or by screw-power.
In modern breech-loadin g guns the shell is drawn out of the barrel about a quarter of an inch by the breaking or swinging open of the breech to expose the rim of the shell, to permit it to be extracted by a pulling device which engages the rim of the shell. It often happens, however, that the shell becomes so firmly bound in the barrel that it cannot be rdrawn out by hand-pulling, and my improvement adapts the device for use in such cases, so that the shell may be drawn by screwpower. My improved device is adapted to be applied to the end of the gun and to the rim of the shellby a sidewise movement, and for this purpose the part that engages the shell and its holding part are both open at the side,
so as to be easily placed sidewise against the' end ot the gun and over the side of the shell.
In the accompanying drawings I have shown in side elevation in Figure 1 the eX- tractor device in the position as applied to the gun, and showing the shell partially drawn. Fig. 2 is a perspective View of the device, the shell-engaging part and its holder being retained in their relative positions to be applied to the gun and to the rim of the shell; and Fig. 3 is a longitudinal vertical section of the device; and Figs. 4 and 5 show modifications which prevent the turning of the screw.
A screw-stem l has a head 2 at one end formedv with three'grooved dogs or catches 3 in triangular relation to flt over and engage the rim of the shell, the dogs having grooves 4 on their inner sides to receive the rim in placing the head against the rimmed end ofthe shell. The holder is an open part of two arms 5, which are connected at one end by a part 6, having acentral non-threaded bore 7, which forms a guide through which the screw-stem passesto hold its dogged head between the arms. The other -end of the holder-arms'are connected by a semicircular band 8, within which the dog is guided by the tubular end of the holder.V This band part is made sernicircular to allow it to be placed over the shell and endwise against the end of the gun-barrel to'perinit the grooved dogs to be slid sidewise over the rim of the shell to engageit.
To maintain the dogged head and the holderband in their proper relative positions to allow the device to be easily-applied to the shellthat is, with the openV sides of these partson the same side of the holder--the tubular part of the latter is formed with a 1in or feather 9, which engages a longitudinal groove l0 on 4the screw-stem, so that the latter can slide freely but cannot turn in the bore of the holder, and thereby keeps the dogged head and the holder-band always in position to be slid side- Wise over the rim of the shell; but for this provision to prevent the turning of the screw the dogged part would have to be adjusted by hand to set it in position at the open side of the holder-band to place it upon the shell.
Instead of the iin engaging the groove in the screw-stem, the dogged head may have pins 11 on its opposite engaging grooves or slots in the holder-arms and the band part, or the screw-stem may have cross-arms 12 for engaging said holder-arms. An armed nut 13 on the screw-stem, bearing against the tubular end ot the holder, serves to draw the shell byturning the nut when the shell cannot be drawn by hand pulling; but it is obvious that the shell, when not tightly bound, may be pulled out by applying the dogged head and pulling on the armed nut. To draw out the shell the gun is held in the left hand and the device is applied sidewise to the shell-rim and supported by the holder-band against the end of the gun-barrel, the dogged screw-stem is then pulled by its armed nut, or the latter is turned against the holder, to use the power of the screw when the shell cannot be drawn by hand.
To prevent fthe possible spreading of the holder-arms under the pulling force of the screw the edges of the band are connected at the ends of the arms so as to serve as a brace, as they would be liable to spread under a great strain in drawing the shell, against the pressure of the half band against the end of the gun. The provision for engaging the screw-stem by a sliding connection with or upon the holder is also important to prevent the grooved dogs from slipping over the rim ofthe shell in drawing the latter by the power of the screw and nut, for, if the screw was free to turn with the nut, it might fail to draw the shell or would not be so effective in its withdrawing action upon the shell. Such a sliding engagement between the screw-stem and the holder part, at one side only of the latter, would be effective for the purpose.
I claim as my improvement- 1. In a shell-extractor for tire-arms, the holder part having a smootl1-bore at one end and a semi-circular band at its other end open at the side, in combination with a screwstem passing through said smooth bore and having ahead formed with grooved-dogs, and
an armed-nut on the screw-stem, for acting against the end of the smooth bored part, the said semi circular band and the screw head being adapted to be placed sidewise over the shell, substantially as described for the purpose stated.
2. In a shell extractor for guns, the holder part having a semicircnlar band at one end open at one side and a smooth-bore at the other end, in combination with a screw-stem sliding through the smooth-bore and having a head formed with dogs, an armed-nut on the outer end of said screw-stein, and a projection on one of said parts engaging a groove on the other part with a sliding function for preventing the turning of the screw in the holder.
3. In a shell-extractor for guns, the combination of the screw-stem having alongitudinal groove and a head having transversely grooved-dogs, with a holder part having at one end a half-circle band open at the side and at its other end a smooth bore for said screw-stein having a tin engaging the stemgroove, and an armed nut on its outer end for the purpose stated.
In testimony whereof I have hereunto signed this specification, in the presence of witnesses, on this 3d day of May, A. D. 1895.
