Specification of Letters Patent. Application filed Y 7,190B- Serial No. 315.577.
Patented Aug. 21 1906. A
T0 0.7], whom it may concern;
Be it known that I, THOMAS C. J OHNSON, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Firearms; and I do hereby declare the following, when taken in connection with the accompanying drawings and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in
Figure l, a broken view in right-hand side elevation of the barrel, fore-arm, fore-arm tip, and lock-nut constructed in accordance with my invention; Fig. 2, a view thereof in front elevation Fig. 3, a broken view, in side elevation, of the barrel stripped; Fig. 4, a detached sectional view of the fore-arm tip; Fig. 5, a view thereof in front elevation; Fig. 6, a detached side view of the lock-nut; Fig. 7, a detached reverse view thereof.
My invention relates to an improvement in firearms, the object being to provide a simple and convenient fore-arm tip constructed with particular reference to being accommodated in position upon the gun-barrel to changes in the length of the fore arm due to atmospheric conditions or otherwise and to avoiding the transverse cutting of the barrel for securing it in lace.
WVith these ends in view my invention consists in a firearm having certain details of construction, as will be hereinafter described, and pointed out in the claims.
In carrying out my invention as herein shown 1 form the barrel 2 at a point adjacent to the front end of the fore-arm 3 with a band or fillet of concentric threads 4, covering a sufficient space to provide for the maximum changes in the position of the forearm tip 5 required to compensate for variations in the length of the fore-arm, as well as changes due to contraction and expansion. In this connection it may be said that notwithstanding the care with which they are made fore-arms will vary slightly in length. They are also subject to changes in len th, due to contraction and expansion. T ese variations are small; but small changes in size become very important in work gaged as fine as the interchangeable parts of firearms. The threads 4 are located just in front of a bearing-surface 6, formed upon the barrel and merging at its rear end into the full diameter of the barrel through a shoulder 7. The said tip 5 is formed with a bearing-sleeve 8, adapted in internal diameter to fit snugly over the bear in -surface 6 and contains a recess or socket 9 or the reception of a tenon 10 at the front end of the fore-arm 3, the rear end of which is supported in the usual way by the frame 11. To secure the tip in place, I employ a locknut 12, the threads of which are adapted to take into the threads 4 upon the barrel. To lock this nut in place, I form shallow notches 13 in its rear face for the reception of a plunger-like lockingpin l4, actuated by a spring 15 and mounted in an inclined socket 16 in the tip, the rounded front end of the pin projecting beyond the front face of the tip for entrance into the said notches 13. The locknut, as shown, is furnished with radial holes 17 for the reception of the pins of a spannerwrench or other implement for turning the nut.
When the gun is assembled, the lock-nu t is turned on the threads 4 on the barrel until it is brought to a firm bearing upon the tip, whereby variations in the length of the forearm to whatever due are compensated for. As the lock-nut is turned home the high points between its notches 13 force the locking-pin 14 to retire against the tension of its spring 15 until the nut has been brought into its final position, when it will be locked against jarring loose by the entrance of the pin into one of its notches. In this way I am enabled not only to compensate for variations in the length of the forearm, but also to avoid the formation in the lower face of the barrel of the transverse notch generally made therein for' the reception of the screw coimuonly used to fix the fore-arm tip in place.
I claim-- 1. In a firearm, the combination with. the barrel and the fore-arm, of a f orearni tip supporting the front end of thc fore-arm and cm.- bracing the barrel, and a lock-nut ad justably mounted upon the barrel in position to engage directly with the front of the fore-arm ti P2. In a firearm, the combination with a barrel havin concentric screw-threads, of a fore-arm, a f ore-erm tip, and a lock-nut engaging with the said screw-threads and with the fore-arm tip for holding the same in place.
3. In a firearm, the combination With a barrel having concentric screw-threads, of a fore-arm, a fore-arm ti supporting the front end of the fore-arm an embracing the barrel at a oint directly to the rear of the said threa s, and a lock-nut engagin with the said threads and ada ted to be rictionally locked with the front face of the tip.
4. In a firearm, the combination With a barrel having concentric screw-threads and a bearing-surface located directly back of the said threads, of a fore-arm, a fore-arm tip supporting the front end of the fore-arm and embracing the said bearing upon the barrel, and a lock-nut turning on the said screwthreads on the barrel and engaging with the front face of the tip.
5. In a firearm, the combination with a barrelhaving concentric screw-threads, of a fore-arm, a fore-arm tip embracing the barrel at a point directly to the rear of the said threads, a lock-nut engaging with the said threads and formed upon its rear face with locking-notches, and a locking-pin mounted in the tip and engaging with the notches of the said nut.
In testimony whereof I have signed this specification in the presence of two subscrib lng Witnesses.
