DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawings, the pressurized can is designated by the numeral 12 and it is seen that it is cylindrical. About the can, a ring designated by the numeral 14 is arranged. The ring includes adjustment means to tighten it about the can and in the preferred embodiment, the adjustment means comprises a housing 16 for a threaded bolt 18 the threads of which are adapted to cooperate with a pattern of slots 20 along the ring length to tighten or loosen the ring about the can upon turning of the screw with a screwdriver.
A support member 22 for a purpose to be described extends radially outwardly of the ring and is rigidly secured thereto as by welding at 26, the ring having a through opening as at 28. In the preferred embodiment the support member may comprise a housing generally designated by the numeral with a longitudinally extending passageway 32 and a longitudinally extending guide slot 34 communicating with the passageway. Within the passageway of the support member or housing a piercing sleeve 36, which has a proximal end 38 and a distal end 40, is slidably captivated for radial movement inwardly and outwardly along the support member, the support member having guide means, that is as in the preferred embodiment shown, the longitudinally extending slot 34 in which the piercing member is engaged for sliding movement only.
The piercing member, as seen in FIG. 3, is provided with a longitudinally extending through. bore 42; and the piercing sleeve or member includes a piercing means 43 extending radially from its proximal end zone and through which there is an opening in fluid communication with the bore of the sleeve member. The piercing means on the end of the piercing sleeve is normally spaced radially outwardly of the ring and is adapted to be slidingly moved radially inwardly past the ring and into piercing engagement with the can side wall to provide a flow path through the piercing means through opening and the sleeve for the contents of the can to escape from the can. 7
A lever 44 is provided for moving the piercing sleeve member radially inwardly and outwardly and toggle means generally designated by the numeral 46 are provided to interconnect the operating lever to the slidable sleeve member and to the support member.
Nipple means 50 are provided on the distal end of the sleeve member to connect to a fitting 52 which in turn is adapted to be connected to a hose or tube leading to a reservoir to be filled with the pressurized contents of the can, such as an airconditioner system tank for freon.
Referring to the toggle system, in the preferred embodiment, the sleeve member 36 includes a rigid arm 54 extending through the guide means or slot 34, which arm is spaced between the distal end of the sleeve member and distally of the ring. Also, clevis yoke means 56 are provided on the radially extending support member at a position which is radially outwardly and in axial alignment with the rigid arm on the sleeve member. The lever 44 has a foot 58 which extends away from a pivotal connection with the yoke 56 at an elbow 60 at the proximal lever end 62; and the distal end of the foot is pivotally connected to a pair of links 64 as at 66, and the other end of the links 64 are pivotally connected to the arm 54 of the sleeve member as at 72 whereby, upon manipulation of the lever from the position shown in FIG. 2, the pivot means 66 will move across a line joining the pivotal connections 70 and 72 between the clevis means and the arm into the position shown in FIG. 3 and, in so doing, advance the piercing means into piercing engagement into the can when it is held thereat. On the extending piercing means, an O- ring 74 is peripherally arranged which nests about the opening which is pierced in the can.
