Abstract

A cross bow which can fire both bolts and pellets comprises a bow attached to a bow slide which performs reciprocating or longitudinal motion relative to a cross bow stock when the cross bow is being cocked. The slide can be maintained in a selected position along the stock by a pawl and ratchet device. To fire pellets or bolts a pellet holder or a bolt pusher is attached to the bow string accordingly.

Claims

1. In a cross bow comprising a stock, a bow, a bow string, a releasable catch for holding said bow string in a cocked position, trigger means operatively associated with said catch for effecting release of said bow string therefrom, the improvement including:

(a) a movable bow slide means to which said bow is attached, said bow slide means being attached to the stock in such a manner that it permits reciprocating motion relative to said stock when the cross bow is being cocked;

(b) slide locking means fixing said slide in different determined positions relative to the stock;

(c) said stock having at least one longitudinally extended guideway conforming to the shape of said bow slide means for guiding of said slide means during its movement.

2. A cross bow according to claim 1, further including cocking means to move said bow slide with said bow attached to it relative to said stock.

3. A cross bow as claimed in claim 2 in which said cocking means include a gear wheel and a gear rack.

4. A cross bow as claimed in claim 2 in which said cocking means includes a lever pivoted at said stock and at least one cocking member-link one end of which is pivotally attached to said lever and another end of which is pivotally attached to said bow slide.

5. A cross bow as claimed in claim 2 in which said stock includes an elongated fore end portion and a butt pivotally attached to the latter, said cocking means including said butt and at least one cocking member-link one end of which is pivotally attached to said butt and another end of which is pivotally attached to said bow slide.

6. A cross bow as claimed in claim 1 in which said slide locking means include a ratchet gear wheel and a spring loaded pawl.

7. A cross bow as claimed in claim 1 in which said bow includes two separate bow halves each of which is attached to said bow slide.

8. In a cross bow comprising a stock, a bow and a bow string, the improvement including:

(a) movable bow slide means to which said bow is attached, said bow slide means being attached to the stock in such a manner that it permits longitudinal on straight line motion of said bow slide means and said bow relative to said stock for cocking of the cross bow;

(b) said bow slide means including bow fastening means fixing said bow on said bow slide means;

(c) slide locking means fixing said bow slide means in different longitudinal positions relative to the stock;

(d) said stock having at least one longitudinally extended guideway conforming to the shape of said bow slide means for guiding of said bow slide means during its movement.

9. A cross bow according to claim 8, further including cocking means to move said bow slide means relative to said stock.

10. A cross bow as claimed in claim 8 in which said cocking means include a gear wheel and a gear rack.

11. A cross bow as claimed in claim 9 in which said cocking means include a lever pivoted at said stock and at least one cocking member-link one end of which is pivotally attached to said lever and another end of which is pivotally attached to said bow slide means.

12. A cross bow as claimed in claim 9 in which said stock includes an elongated fore end portion and a butt pivotally attached to the latter, said cocking means including said butt and at least one cocking member-link one end of which is pivotally attached to said butt and another end of which is pivotally attached to said bow slide means.

13. A cross bow as claimed in claim 8 in which said slide locking means include a ratchet gear wheel and a spring loaded pawl.

14. A cross bow as claimed in claim 8 in which said bow includes two separate bow halves each of which is attached to said bow slide means.

15. In a cross bow comprising a stock, a bow and a bow string, the improvement including:

(a) a movable bow slide to which said bow is attached, said bow slide being attached to the stock in such a manner that it permits longitudinal motion forward and backwards relative to said stock for changing of a bow tension;

(b) said slide arranged to be stopped during its longitudinal motion forward and backwards in a plurality of possible positions relative to the stock and to be locked in each of said positions by slide locking means;

(c) said stock having at least one longitudinally extended guideway conforming to the shape of said bow slide for guiding of said slide during its movement.

16. A cross bow according to claim 15, further including cocking means to move said bow slide with said bow attached to it relative to said stock.

17. A cross bow as claimed in claim 15 in which said bow includes two separate bow halves each of which is attached to said bow slide.
