z claims. (cl. 42-66) This invention relates'to a safety lock for firearms of the type having a barrel and a revolving cylinder hav- -ing cartridge receivingV chambers for selective movement into registry with and firing through the barrel. In such devices as, for example, revolvers, the cylinder is movable -to an inoperative (loading) position out of alignment with the barrel. It frequently happens that the revolver is accidentally or without authority restored to operative condition and iired, often with tragically fatal results.
The device of this invention is a safety lock so designed as to hold and lock the cylinder in inoperative position with complete safety and without danger of accidental iiring. The device may be readily removed from the rearm to restore the latter to ring condition.
In the accompanying illustrative drawings, similar reference characters indicate like parts:
Figure 1 is an exploded, elevational, partly sectional view of parts of the safety device of the invention, disassembled,
Figure 2 is a fragmentary, vertical sectional view of a firearm cylinder showing parts of the device of the invention initially inserted into a chamber thereof,
Figure 3 is a similar view showing the remaining parts of the device of the invention applied to said chamber,
Figure 4 is a similar view showing the complete device applied to the chamber, showing, in dotted lines, the outline of a typical revolver in connection with which the invention is adapted `to be used,
Figure 5 is an enlarged, elevational, partly fragmentary view of parts of the device of the invention, in one form thereof, and
Figure 6 is a similar view of another form thereof.
As shown in the drawings, the invention is designed for use with rearm device such as a revolver 30 having a cylinder opening 29 in which a cylinder 10 having a series of chambers |11 to receive the cartridges, is movable for registry with and ring through the barrel 28 of the revolver, said cylinder being displaceable from alignment with the barrel for loading the revolver.
In Fig. 4 of the drawings, the cylinder may be visualized as moved out of the cylinder opening 29 of the revolver so as to render the latter inoperative. The device of the invention maintains the cylinder in such inoperative position until said device is removed from the cylinder, as follows:
Pursuant to the invention, a casing 13 is proportioned to smoothly slidably fit into chamber 11 of the cylinder and is provided with an enlarged head 17 at one end adapted to abut against an end 14 of the cylinder. An elongated pin l15 is secured to or formed unitarily with casing 13 and is proportioned to be of greater length than the casing so that the free end 18 of the pin will extend out beyond the other end r16 of the cylinder when the casing 13 is so positioned in the cylinder chamber 11. A tubular member 20 is provided, proportioned at one side of a shoulder 211 formed therein to be of greater diameter than the chamber 11 of the cylinder 10 and at Patented July 5, 1960 the other side of the shoulder of less diameter and complementary means such as 23, 24, 25 (Fig. 5) are provlded to secure the tubular member to the free end 1S of the -pin and thus to prevent accidental removal of the pin from the cylinder chamber.
It will be apparent from a consideration of Fig. 4 that the device is thus applied to the revolver with the barrel 28 of the revolver pointed away from the user and is likewise disengaged from the revolver in that position of the parts- With complete safety to the user. To remove the casing 13 from the cylinder chamber, means 23 are disengaged from the pin l15; such disengagement may be readily and rapidly effected in the dark, while pointing the revolver away from the er.
As shown in Fig. 4, the casing 13 may be provided with a spring 19 movably positioned on the pin 15 and preferably so proportioned as to be freely, slidably coiled on the pin within and out of the casing 13. The tubular member is proportioned at one side of shoulder 21 formed thereon to slide within the casing (Fig. 3) and to cornpress the spring in so doing. Shouldered portion 21 (Fig. 4) defines a remaining portion of the tubular member 20 of greater diameter than the cylinder chamber 11 and means 25 are provided engaging the pin (Figs.V 5 and 6) and proportioned to engage the end of member 2li holds the shouldered portion of member 20 against member Z3 on the end of pin 15 responsive to spring tension so that the revolver will be rendered inoperative and may not be rendered operative until the means 23 engaging the pin are disengaged therefrom, whereupon (Fig. l) the tubular member 2t) and the pin maybe separated so that the casing 13 and parts carried thereby may be removed from the chamber of the cylinder and the latter restored -to ring position. The said means 23 may (Fig. 5) comprise a disc of greater diameter than the free end 18 of the pin and having a threaded stud 24 extending therefrom for engagement with a complementary, internally threaded recess 25 of the pin 15 or, as in Fig. 6, the means 23a may comprise an internally threaded ring 216 engaging a reduced, externally threaded portion 27 of the pin 15.
The disclosure herein will enable those skilled in the art to practice the same by the utilization of means such as shown specifically in the drawing, for practicing the device of the invention. The above described devices and all others coming within the scope of the appended claims shall be deemed to be Within the purview of and covered by this invention.
A shouldered portion 21 (Figure 4) is provided on the tubular member 2.0 delining a remaining portion of the tubular member 20 of greater diameter than the diameter of the bore 11, and means 25 are provided engaging the pin (Figures 5 and 6) and proportioned to be engaged lby the shouldered portion 21 of the tubular member to fix the positions of the tubular member responsive to the spring tension to that shown in Figure 4. The barrel cannot be moved from said inoperative position and into alignment with the tube of the firearm until the means 23 engaging the pin are disengaged therefrom, whereupon (Figure l) the said tubular member 20 and the pin are Separated so that the casing 13 and parts carried thereby may be removed from the bore of the barrel, and the latter restored to ring position. The said means 23 may (Figure 5) comprise a disc of greater diameter than the free end 18 of the pin and having a threaded stud 24 extending therefrom for engagement with a complementary, internally threaded recess 2S of the pin 15 or, as in Figure 6, the means 23a may comprise an internally threaded ring 26 engaging a reduced externally threaded portion 27 of the pin 15.
The disclosure herein will enable those skilled in the art to practice the same by the utilization of means such as' shown specifically inv the drawing, for practicing the device of the invention. The above described devices and all others coming within the scope of the appended claims shall be deemed to be within the purview of and covered by this invention;`
Having thus described myinvention, what I; claim as new and desire'.to'secure by"Letters Patent isz' '1'. A safetydevicef foruse with a revolver having al diameter of the cylinder chamber and a portion of smaller diameter than the diameter of the casing slidably engaging said casing and means engaging said tubular member and said pin to removably secure said tubular member to said pin.
2. In a device as set forth in claim 1, said means engaging said pin and tubular member including a head of greater diameter thanr'thepinf-and of smaller diameter than the enlarged portion of the tubular member, and a spring positioned on said' pin and engaging said casing and said tubulark member smaller portionand urging said tubular member into engagement with saidhead.
