9 Claims. ((31. 42--70) This invention relates to a combination safety lock or device for firearms in general and particularly to such a lock readily useable with small arms in the revolver class.
Prior devices of this general type usually consist of a lever-operated cam to prevent cocking or triggering the weapon but no combination lock to control the firing of the weapon is provided. Other types of safety devices for firearms are available, such as the safety means illustrated in U. S. Patent No. 2,182,693, but the large number of mechanical parts makes such devices impractical. By the present invention, the combination safety lock includes a release mechanism for permitting triggering of the weapon and this release mechanism may be operated only upon the user having knowledge of the lock combination. Furthermore, the lock combination, While being relatively simple and composed of a minimum number of parts, may be changed or altered at the will of the manufacturer to meet various requirements of the user, to prevent unwarranted or unauthorized use of the weapon, and to preclude accidental discharge thereof.
Accordingly, it is an important object of this invention to provide an improved safety lock and release mechanism for a firearm which has a combination lock arrangement.
Another object of this invention is to provide an improved combination safety lock and release means for a firearm which is incorporated in the handle or hand-grip of the revolver and which may be operated by proper sequence movement by, for example, the middle and ring fingers of the user.
A still further object of this invention is to provide an improved safety device for a firearm of the type described which is inexpensive to manufacture, is durable, and which is foolproof in operation to preclude accidental and unauthorized use thereof.
Other objects and advantages will be obvious from the following description taken with the accompanying drawings, in which Figure 1 is an elevational side View of a revolver incorporating one form of the combination safety device of this invention;
Figure 2 is an elevational side view with the handle broken away;
Figure 3 is a sectional view taken along the line 3-3 of Figure 1 but only including certain of the parts;
Figure 4 is a sectional elevational view taken along the line 4 4 of Figure 1;
Figure 5 is a sectional view taken along the line 5-5 of Figure 2;
Figure 6 is an elevational side view of a revolver incorporating a second form of this invention;
Figure 7 is a side elevational view thereof with a portion of the handle and the cover plate removed;
Figure 8 is a sectional view taken along the line 8-8 of Figure 7;
Figure 9 is a sectional view taken along the line 9-9 of Figure 7; and
Figure 10 is a sectional view taken along the line 10-19 of Figure 7.
It is to be understood that there are many occasions where a combination safety lock and release mechanism for firearms may be employed such as when the user desires preventing unwarranted, unauthorized, and accidental use of his weapon. In both forms of the invention, to prepare the firearm for firing or triggering, a lever or button must be maintained depressed by the user and to release the locking lever from the main spring of the weapon it is necessary to depress an additional button or lever a predetermined number of times and this constitutes the combination.
Referring to the embodiment illustrated in Figures 1-5, inclusive, the numeral 1 represents a conventional firearm in the form of a revolver having the usual hammer 2, trigger 3, main spring 4 and handle 5. In typical operation, partial actuation of the trigger may cock the hammer, thus causing the spring 4, connected to the hammer, to become bowed, and further movement thereof may trigger or fire the gun through release actuation or movement of spring 4 and thereby snapping or release pivoting of the hammer. By the present invention, spring 4 may not be actuated or released to unbowed condition until locking lever 6 is released from engagement with the main spring 4 or released from a position Where it provides a stop preventing movement of spring 4.
The locking lever 6 is pivotally mounted within the casing or hand-grip 5 at 7 and includes a head or shoulder portion 8 for engagement with the main spring 4 and a U-shaped end portion 9 which will be further described hereinafter. Rotatably mounted at 11 within the handle or casing 5 is a ratchet wheel or member 12, said wheel having near one end thereof adjacent the periphery teeth 13 and at the other end thereof adjacent the periphery, but on the opposite face or side, teeth 14. Also positioned on the same face of wheel 12 as are the teeth 13 is a protruding lug or projection 15 and, as shown in Figures 2 and 4, one leg of the U 9 normally rests against this abutment 15, as illustrated in Figure 4, and the other side or leg adjacent an abutment or projection 16 projecting from the opposite face or surface of wheel 12, namely the face upon which teeth 14 appear. It will be apparent hereinafter that the other leg rests on projection 15 when the head 8 is pivoted to the dotted line position of Figure 4. As the parts are illustrated in Figures 1 and 2, the wheel 12 and the lever 6 are in their normal positions with the lever head 8 locked or depressed within spring 4. A spring 17 is connected within casing 5 to the wheel 12 at 18 and to the casing 5 at 19 and this spring functions to maintain the wheel 12 in its normal position.
For actuating rotation of wheel 12, there is provided a pawl 21 pivotally mounted by means 22 to a lever 23 extending exteriorly of easing 5, the lever 23 in turn being pivoted by any suitable means 24 to the casing 5 and being accessible and adapted for actuation on the outside of the casing 5 and preferably by the ring finger of the user. Spring 25 is mounted on the handle 5 at 26 and connected to the pawl at 27 by pin 30 for normally maintaining the pawl 21 and lever 23 in their normal positions. Also pivotally mounted on casing 5 by any suitable means 28 is a lever 28 which extends exteriorly of the casing 5 and is adapted for pivotal actuation by preferably the middle finger of the user. Lever 28 has an abutment 29 thereon engageable with the exterior surface of easing 5 for limiting the amount of pivotal movement thereof. Connected to the interior of the casing is a leaf spring 31 and this spring has one end 32 thereof adapted for engagement with teeth 13 of the wheel 12 upon suitable depression of lever 28, spring 31 and lever 28 being urged to their normal positions, upon releasing lever 28 Therefore, spring 31 functions as a retaining pawl for engagement with teeth 13 and to thereby, when lever 28 is depressed, hold the wheel 12 in the rotated position caused by actuation of pawl 21. In connection with driv-' ing pawl 21, whichis normally biased into engagement with teeth 14, suitable means comparable to the'type shown in U. S. patents to Smith 656,380, Christie et .al. 1,253,150 and Pfantz 661,704 must be employed to release or disengage pawl 21 and the teeth 14 when the wheel 12 is being returned to its normal position by the spring 17.
In operation, the parts are as shown in Figures 1 and 2 with the head 8 depressed within spring 4 as illustrated in Figure 4. To prepare the gun for firing or triggering, lever 28 is depressed and maintained in this condition whereby end 32 engages a tooth 13 of wheel 12. Thereafter, lever 23 is depressed and each depression causes, due toengagement of pawl 21 with the teeth 14, a rotat ive movement of the wheel 12in the direction ofthe arrow shown in Figure 2. The device illustrated has been arranged so that three depressions of lever 23 while maintaining lever 28 depressed will result in movement of wheel 12 a suflicient amount to cause the head 8 to be pivoted out of engagement with spring 4 as illustrated-in Figure 4, and this pivoting actuation of the head is caused by a'camming action due-to disen gagement and engagement of the U-shaped fingers of end portion 9 'with the protuberances and 16 during rotative movement of .the wheel 12. When the parts are in this position, the trigger may be operated and the gun fired and, repeated firingmay take place as long as lever 28 is maintained depressed. To release plate 12,
andto again lock the parts in non-firing position, it is a merely necessary to release lever 28 and this permits spring 17 to function to return the wheel and the head 8 to its normal locked position.
A modified form of the invention is illustrated in Fig ures 610, inclusive. -Within casing 5' is mounted for substantially vertical movement an elongated ratchet member 41, said member normally being maintained in the position illustrated in Figure -6 due to the action cated portion'52 to which thepawl 47 is pivotally con- -nected and pawl 48 is integrally and rigidly connected to member 53 which also pivots on a bifurcated portion 54 of-arm 55. The bifurcated portions 52 and 54 may be moved inwardly by depressing of buttons 45 and 46, respectively, and their outward movement is maintained by compression springs '56and '57 which are connected with a cover plate 58 rigidly mounted in the-casing on suitable projections such as at 59.
Pawl 48 is adapted forengagement-with teeth 61 of ratchet member 41'and pawl 47 is adapted for engage- V ment with teeth 62 of member 41. While member 41 maybe movedve'rtically within the casing upon actuation of'the- pawls 48 and 47, sidewise movement thereof is prevented due to lugs. 63 and configuration of easing 5' which,;i1j1 effect, provide a: passageway or guideway for the substantially vertical movement of member 41.
p The lockinglever 64 is provided with ahead 65 for engagement with the main spring 66' of the revolver, the locking lever 64 being pivoted to the casing' at 67 and,maintain'ed in its locking positiondue to spring 68 which normally forcesv the L-shaped bottom '69 -of member 64 toward member 41 and in abutting engagement therewith. It is to benoted that member 41 is provided with a groove 71 which may receive the angle portion 69 of lever 64 'upon a predetermined vertical movement of member 41 and, when .thisoccurs, the spring 68 forces the Wedge end of part 69 into the groove 71 to pivot lever 64 and thus the head 65 maintains the solid line position shown in Figure 8.
In operation, the parts are as illustrated in Figure 6, and with the head 65, due to part 69 being out of engagement with the groove 71, in depressed condition with relation to spring 66.v To permit firing of the gun, button 46 is maintained depressed and the pawl 48 engages a tooth 61 and, in effect, is the retaining pawl. .Thereafter, the button is depressed a number of times to operate the driving pawl 47fto elevate member 41 against the action of spring 42. As the device illustrated is constructed, three depressions of button 45 will result in elevation of member 41 to a position whereby part 69 is forced by spring 68 into the groove. 71 and this results in the head 65 being" positioned as shown in Figure S-and permits, firing of the gun. the spring '66 and locks against triggering upon release of buttons 45 and 46. .7 i
It should be readily apparent andfappreciated from the. description of the parts and operation of both eme. bodiments that a safety lock and release'mechanism' is provided which fulfills the objects of'the' invention here;
inbefore enumerated. I
