Cylinder impeller for revolving guns and revolver
A cylinder impeller for revolvers, which transmits the trigger pulling movement to a cylinder revolving movement. The impeller includes a cover having inside it a track; a one-piece body having a plate and a slider, said slider being able to slide within and relative to the cover; and a spring arranged between the body slider and the surface of the cover track. Therefore, the cover and the body slide one relative to the other and against the spring action, thus varying the overall length of the impeller and compensating and absorbing possible teeth machining variations of the cylinder extractor.
1. A cylinder impeller for revolvers, which transmits a trigger pulling movement on a cylinder revolving movement, said impeller comprising:
a cover provided with a protrusion on an upper portion thereof acting on cylinder teeth, and the cover defining a track;
a one-piece body comprising a plate and a slider, said plate receiving an impeller pivoting pin on a trigger, and said slider being able to slide within and in relation to the cover; and
a spring disposed between a slider upper end of the one-piece body and a surface defining a slider upper limit of the cover,
wherein said cover comprises, at a lower end of the cover, an oblong opening, and the slider of the one-piece body comprises a hole configured to receive a pin, said pin limiting travel of the one-piece body relative to the cover by mechanical interference against the oblong opening.
2. The impeller according to claim 1 , wherein the slider upper end comprises a protrusion which receives and centers a spring lower end.
3. The impeller according to claim 1 , wherein said cover comprises a plate shape comprising on a side portion of the plate shape an edge, and wherein an inside of said edge defines a cross-section track, wherein the cross-section track is triangular.
4. A revolver comprising an impeller which transmits a trigger pulling movement on a cylinder revolving movement, said impeller comprising:
a cover provided, in an upper portion, with a protrusion acting on cylinder teeth, and the cover defining a track;
a one-piece body comprising a plate and a slider, said plate receiving an impeller pivoting pin on a trigger, and said slider being able to slide within and in relation to the cover; and
a spring disposed between a slider upper end of the one-piece body and a surface defining a slider upper limit of the cover,
wherein said cover comprises, at a lower end of the cover, an oblong opening, and the slider of the one-piece body comprises a hole configured to receive a pin, said pin limiting travel of the one-piece body relative to the cover by mechanical interference against the oblong opening.
5. The revolver according to claim 4 , wherein the slider upper end comprises a protrusion which receives and centers a spring lower end.
6. The revolver according to claim 4 , wherein said cover comprises a plate shape comprising on a side portion of the plate shape an edge, and wherein an inside of said edge defines a cross-section track, wherein the cross-section track is triangular.
