Description
June 29, 1965 o. N. OLSON VIBRATION DAMPER FOR FIREARMS Filed June 29. 1964 AT TORNE YS ML MO M m United States Patent 3,191,336 v VIBRATHQN DAMPER FOR FIREARMS file N. Olson, 2909 Quentin, Minneapolis, Minn. Filed June 29, 1964, Ser. No. 378,669 3 Claims. (Cl. 42-1) My invention relates to improvements in hand guns or pistols. More specifically, my invention provides a novel means for dampening or decreasing the horizontal vibrations of the muzzle end of the barrels of such hand guns.
The primary object of my invention is the provision of novel vibration-dampening means which will automatically reduce horizontal vibratory impulses to a minimum so as to increase the eificiency and accuracy of a pistol upon which it is installed.
A further object of my invention is the provision of a device of the class described which is relatively inexpensive to produce and which needs no servicing ormaintenance.
A further object of my invention is the provision of a device of the class described which may be built into a conventional gun or applied thereto as an attachment with a minimum of skill and labor.
The above and still further objects of my invention will become apparent from the following detailed specification, appended claims, and attached drawings.
Referring to the drawings wherein like characters indicate like parts throughout the several views:
FIG. 1 is a view in side elevation of a conventional revolver-type pistol showing my novel invention in operative position thereon;
FIG. 2 is an enlarged view in front elevation as seen from the line 2-2 of FIG. 1;
FIG. 3 is a view in vertical section as seen from the line 33 of FIG. 1 on the same scale of FIG. 2; and
FIG. 4 is a view in vertical section taken on the line 44 of FIG. 2, the gun barrel not being shown.
Referring with greater particularity to the drawings, the numeral 10 indicates in its entirety a conventional revolver-type pistol, the hand grip identified by 11, the trigger by 12, the bullet-receiving cylinder by 13, the barrel by 14, front sight by 15, rear sight by 16, the hammer by 17. Mounting one end of the cylinder 13 for rotation is a spindle 18, forward movements of which are limited by stop member 19 fast on the under side of the barrel 14 adjacent the muzzle end 20 thereof.
My novel dampening attachment comprises an elongated body 21 which defines an axially extended fluid-type chamber 22 having a transversely cross-sectionally arcuate bottom wall 23, for a purpose which will hereinafter become apparent. As shown, one end wall 24 of the body 21 is provided with a plug 25 for insertion into the chamber 22, and removal therefrom of liquid metal such as mercury 26. For a purpose which will also be explained hereinafter, the chamber 22 is only partially filled, as indicated by FIGS. 3 and 4.
As shown, the body 21, in overlying relationship to the chamber 22, is bifurcated to provide legs 27, 23 and a longitudinally extended recess or channel 29 for the reception of the stop member 19 carried by the muzzle end 20 of the barrel 14. The opposed upper surfaces of the legs 27, 28 are formed to the contours of the barrel 14, as indicated at 27a, 28a, respectively.
Secured to opposite sides of the body'21 with their lower ends received flush within recesses 30 are longi tudinally spaced opposed pairs of arcuate resilient gripping jaws 31, 32. For the purpose of imparting releasable pressure to the jaws 31, 32, mounting screws 33 are pro vided, as shown in FIG. 4. 7
When my novel attachment is in the operative position of FIG. 1, it functions as follows in the minimizing or dampening of horizontal vibrations. Upon initial movement of the muzzle end 2t) of the barrel 14 in one direction, as indicated by the dotted arrow in FIG. 3, the entire body of the mercury 26 within the chamber 22 is caused to assume the dotted line position of this figure. From this point on, subsequent vibratory movements are dampened by the counter-movement of the mercury 26 within the chamber 22. The arcuate bottom wall 23 of the chamber 22 obviously permits the entire body of the mercury 26 to move freely within the chamber to effect this vibration-dampening counter-movement.
My invention has been thoroughly tested and found to be completely satisfactory for the accomplishment of the above objects; and while I have disclosed a preferred embodiment thereof, same may well be capable of modification without departure from the scope and spirit of the appended claims.
What is claimed is:
1. In a pistol having a barrel (a) means for dampening the horizontal vibrations of the muzzle end of the barrel thereof,
(b) said means comprising structure associated with said muzzle end defining an axially elongated fluidtight chamber positioned below said barrel and having an axis substantially parallel to the axis of said barrel,
(0) said chamber having a transversely cross-section ally arcuate bottom wall,
(d) a substantial air space in the upper portion of said chamber and liquid metal occupying the lower portion of said chamber to permit free dampening move ment of said liquid metal therein.
2. A vibration-dampening attachment for pistols comprising:
(a) structure defining an axially elongated fluid-tight chamber having a transversely cross-sectionally arcuate bottom wall,
(b) fluid metal partially filling said chamber and providing a substantially unoccupied space thereabove in said chamber for free dampening movement of said liquid metal,
(c) and means for detachably securing said structure to the muzzle end of the barrel of said pistol with the axis of said chamber in underlying generally parallel relationship with the axis of said barrel. 3. The structure defined in claim 2 in which said means comprises opposed arcuate resilient gripping jaws, and means for releasably imparting gripping pressure to said aws.
