T. c. JOHNSON. TUBULAR MAGAZINE FIREARM.
APPLICATION FILED JAN.- 8, 1906.
thefr THOMAS C. JOHNSON, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO THE HAVEN, CONNECTICUT,
TUBULAR-MAGAZINE FIREARM.
Application filed January 8,
Patented May 1, 1906.
Haven, in the county of New Haven and I State of Connecticut, have invented a new and useful Improvement in Tubular-Magazine Firearms; and I do hereby declare the following, when taken in connection with the accompanyin drawings and the figures of reference marIied thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and re resent, in
Figure 1, a roken view, partlyin side elevation and partly in section, of a gun containing myimprovement Fig. 2, a detached front view of the fore arm and magazine with the nut removed; Fig. 3, a detached inside view My invention relates to an improvement 11 that class of tubular-magazine firearms in which the magazine is furnished at its front end with a fore-arm tip in the form of a nut, the object being to provide a simple and effective yielding nut-lock for preventing the nut from jarring loose in firing.
With these ends in view my invention consists in a firearm having certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in theclaims.
In carr 'ng out my invention as herein shown I orm a circular series of shallow locking-notches 2 in the front face of a ringlike tenon 3, set into and secured within but projecting forward beyond the front end of a wrought-metal fore-arm 4, the rear end of which is furnished with a U-shaped tenonpiece 5, set into and secured within but proecting rearward beyond the fore-arm and having a rib or tenon 6 to enter a groove 7 in ont of the gun frame or receiver 8. The locking-notches 2 are engaged by a yielding nut lock consisting of a friction-plunger 9, having an enlarged base and located in a circular chamber 10 in a nut 11, constituting, as it were, the fore-arm tip. The said plunger is yieldingly held in place by a coiled spring 12, located in the chamber 10, in which it is co edbymeans ofascrew 13. Thesaidnut is internally threaded, and thus adapted to be screwed almost home, the rounded nose. of
the yielding plunger 9 begins to ride over the partitions between the notches 2 against the tension of the spring 12, whi
tension as the nut is turned home until, finally tension of the spring has been so much in- I creased that it will old the plunger in engagement with one of the locking-notches with force enough to prevent the nut from being jarred loose in firing the gun but the power of the spring is not, of course, enough to prevent the spring from yielding and the plunger from riding from notch to notch when manual force is applied for unscrewing the nut.
would therefore have it understood that I do bination with the fore-arm thereof, of a tubular magazine passing through the said forearm, a fore-arm tip in the form of a nut applied to the front end of ing nut-lock mounted in the nut and coacting with the front end of the fore-arm to prevent the nut from jarring loose.
2. In a tubular-magazine firearm, the combination with the fore-arm thereof, of a tubular magazine passing through the said forearm, a fore-arm tip in the form of a nut applied to the front end of the magazine, a ringlike tenon-piece mounted in the front end of the fore-arm, and a yielding nut-lock mounted in the said nut and coacting with the said Itenon-piece to prevent the nut from jarring oose.
3. In a tubular-magazine firearm, the combination with a wrought-metal fore-arm, of a the front end of the magazine, a ring-1ike specification in the presence of two subscribtenon mounted in the front end of the ing Witnesses. Wrought-metal fore-arm and formed with a circular series of looking-notches, and a yield- THOMAS JOHNSON 5 ing nut-lock coacting with the said notches Witnesses:
