To all whom it may concern: 9
Be it known that I, JOSEPH TAMBOUR, subject of the Emperor of Austria-Hungary, residing at Nanterre, near Paris, France, have invented certainnew and useful Improvements in SafetyLocks for Revolvers,
Pistols, or theLike, of which the following preferably by the ring whereby the pistol is carried.
Inthe accompanyingdrawing the lnvention is shown applied to a revolver having a 7 known automatic safety device, the parts being in the safety position.
Figures 1 and 2 are sectional elevations of 1' the revolver, the safety lever being locked and the hammer uncooked in Fig. l and the safety lever unlocked and the hammer cocked in Fig. 2. Fig. 3 is a detail view.
The safety mechanism consists of a lever 17 actuated by its spring 8 and pivoted at a and abutting at 0 against the hammer and at (Z against the sear so that the hammer can only be cooked or the trigger pulled, when the lever is pressed into the stock.
For the purpose of locking the safety lever in the safetyposition there is pivoted to the frame ofv the stock at e a locking lever 7 which is subject to the pressure of the main spring 9 and is kept thereby. in the locking position (Fig. 1) between two lugs h on the head of a bolt z' in which position its free end abuts against an arm is on the safety lever b. In this case the bolt z'is fixed to the block of the ring 10 so that when the. latter is V this'cavity are four radial grooves m at right angles to eachother with which correspond ing ribs n on the flange of the block of the ring 10 are kept in engagement by the action of spring 0.
Then the block is turned by means of the ring 79 the spring 0 is put into compression by ribs 0% leaving the grooves m and determines the entry of the ribs into the next grooves with which they register; thus the bolt 2' has four positions, two corresponding with the locked position of lever b and two with the free positionthereof.
hen the ring 22 and locking lever f are in the position shown in Fig. 2, the pistol may be discharged the lever 6 being pressed into the stock for the purpose; the inclined surface 1' on the arm is thereupon engages a correspondingly inclined surface on the lever f and raises the latter, thus compressing the main spring so that when pressure is relieved from the lever 12 the latter is returned to normal'position not only by the action of the spring 8 but also by action of the spring g exerted through lever f.
1. In safety locks for pistols and the like, in combination with the stock and the main spring, of'a safety lever, a locking lever coacting with the safety lever and engaged by the main spring, and an exteriorly projecting and operative means for putting the look ing lever into and out of the position in which it looks the safety lever.
2. Ina safety lock for'pistols and the like, in combination with t e stock and the main spring, of a safety'lever, a locking lever coacting with the safety lever and engaged by the main spring, and a rotatable bolt seated in and projecting through the stock and hav ing a ring on its outer end, the bolt having lugs to engage the locking lever and operative to move the latter lever-into and out of locking position relatively to'the safety lever. 3. In a safety lock for pistols and the like, in combination with thestock and the main spring, of a safety lever, a locking lever'coacting with the safety lever and engaged by the main spring, and a spring-pressed bolt rotatably mounted in the stock for moving the locking lever and having ribs on a portion thereof and an exteriorly projecting operating extremity, the stock having crossed grooves for reception of the ribs.
4. In a safety lock for pistols and the like, in combination with the stock and the main spring, of a safety lever having an inclined surface, a locking lever coacting with the 5 i l locklng lever being engaged by the mam i i i l safety lever and having an inclined surface 5 corresponding to the inclined surface of the said safety lever and operatin to bring the safety lever back to its normal position, the
spring, and means for moving the locking lever 111 and outof engaglng position wlth relatlon t0 the safety lever.
In testimony whereof I have hereunto set my hand in presence of two subscribing wit- 19 nesses.
