Abstract

1456650 Syringes A COLOMBO and L BARBAGLIA 23 Nov 1973 [25 Nov 1972] 54562/73 Heading A5R A dental injection gun comprises a handle 16, with a trigger 12 pivoted via a bracket 9 to a lug 5 located around a transversely ringed pusher 6 acting on the piston of a syringe 1 located in a slotted holder 2, trigger 12 when pulled towards handle 16 causing the lug to move against the bias of a torsion spring around pivot 7 from the position shown through a position in which lug 5 extends perpendicularly to the longitudinal axis of pusher 6, thus moving the pusher 6 stepwise against the action of pins 15 biased by leaf springs 14 and which project laterally through holder 2 to engage a ring on the pusher. On release, the trigger 12 is acted upon by a leaf spring 17 in the handle via a rod 20 to move the pusher away from the syringe piston. Knob 8 permits longitudinal adjustment of the pusher and prevents the latter passing completely through lug 5.
