Abstract

A dispenser (10) for cartridges includes at least one piston rod (16), an advancer (20) that can be coupled incrementally to the piston rod (16) in order to move the piston rod (16) in a dispensing direction (R), and it also includes a selectively adjustable controller (22) for the variable pre-selection of the path of travel (D) of the piston rod (16) that, once it has traversed the pre-selected path of travel, uncouples the advancer (20) from the piston rod (16).

Claims

1. A dispenser for cartridges, the dispenser comprising:

at least one piston rod;

an advancer coupleable incrementally to the piston rod to move the piston rod in a dispensing direction; and

a selectively adjustable controller for variable pre-selection of a path of travel of the piston rod, the controller, once the piston rod has traversed the pre-selected path of travel, uncoupling the advancer from the piston rod.

2. The dispenser as recited in claim 1 wherein the controller is affixable onto the piston rod via a lock, and further comprising an actuator on the advancer, the controller movable towards the actuator.

3. The dispenser as recited in claim 2 wherein the controller is selectively affixable to the piston via the lock.

4. The dispenser as recited in claim 2 further comprising an unlocker for the piston rod coupled to the actuator.

5. The dispenser as recited in claim 2 wherein the lock has a clamp engaging with the piston rod.

6. The dispenser as recited in claim 5 wherein the clamp forms a wedge against the piston rod.

7. The dispenser as recited in claim 5 wherein the clamp has a cutout, the piston rod extending through the cutout, the clamp tiltable in order to be clamped onto the piston rod.

8. The dispenser as recited in claim 2 wherein the lock is mounted so as to swivel to activate the controller.

10. The dispenser as recited in claim 2 further comprising a return, the return, after the controller has been deactivated, moving the piston rod opposite to the dispensing direction and back into the starting position.

11. The dispenser as recited in claim 10 wherein the return has a spring engaging with the controller.

12. The dispenser as recited in claim 2 wherein the controller is automatically unlocked after the piston rod has been uncoupled from the advancer.

13. The dispenser as recited in claim 1 further comprising a setter on the controller to set the path of travel of the piston rod.

14. The dispenser as recited in claim 13 wherein the steer includes a movable stop.

15. The dispenser as recited in claim 1 wherein the controller is movable into a deactivated position disengaged from the piston rod.

16. The dispenser as recited in claim 1 wherein the at least one piston rod includes two parallel piston rods, the controller mounted on the two parallel piston rods.

9. The dispenser as recited in claim further comprising a lever on the lock to deactivate the lock.
