Abstract
Abstract This disclosure relates to an adaptation of a conventional vacuum closing machine for closing flexible containers. A flexible container, such as a ham can, is filled with the product and delivered to the closing machine. The container, together with a closure therefor, are separately moved into the interior of the closing machine and are separately supported therein. Thereafter, mechanism is actuated to move a vacuum pot into a sealed position around the container and closure, and the lifting of the closure off of the support therefor by a mold, which mold receives the container and both supports and shapes the container. After a vacuum has been drawn in the pot, the container with the closure sitting thereon is moved by the mold into a seaming position. The machine includes a special stop for positioning a container on the container support and special pusher mechanism for effecting the feeding of containers and closures to the machine and for discharging closed containers from the machine.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
95 words
In combination with a support having an upper surface and a periphery, a retractable stop, means mounting said stop for movement between a retracted position beneath said upper surface and within said periphery of said support and a projecting position at one edge of said periphery and above said upper surface of said support, power means mounted beneath said support for shifting said stop between said positions, and said means mounting said retractable stop includes a pivot pin and an elongated slot connection whereby movement of said retractable stop is combined sliding and pivotal movement.
Claim 2
Dependent Claim
95 words
In combination with a support having an upper surface and a periphery, a retractable stop, means mounting said stop for movement between a retracted position beneath said upper surface and within said periphery of said support and a projecting position at one edge of said periphery and above said upper surface of said support, power means mounted beneath said support for shifting said stop between said positions, and said means mounting said retractable stop includes a pivot pin and an elongated slot connection whereby movement of said retractable stop is combined sliding and pivotal movement.
Claim 3
Dependent Claim
21 words
the combination of claim 1 wherein said power means for said retractable stop is of the straight line reciprocating movement type.
Claim 4
Dependent Claim
26 words
The combination of claim 1 wherein said support includes means defining said slot, and said pivot pin traverses said slot and moves along the length thereof.
Claim 5
Dependent Claim
46 words
The combination of claim 1 wherein said stop is part of a generally T-shaped member defined by a cross arm and a leg projecting generally medially thereof, said leg carries said pivot pin, and said pivot pin traverses and moves along the length of said slot.
Claim 6
Dependent Claim
73 words
The combination of claim 1 wherein said stop is part of a generally T-shaped member defined by a cross arm and a leg projecting generally medially thereof, said leg carries said pivot pin, said pivot pin traverses and moves along the length of said slot, and one end of said cross arm is moved from a generally horizontal position to a generally vertical position upon motion of said pivot pin along said slot.
Claim 7
Dependent Claim
23 words
The combination as defined in claim 5 wherein said leg carries said pivot pin and said pivot pin is disposed within said slot.
Claim 8
Dependent Claim
102 words
In combination with a support having an upper surface and a periphery, means for vertically reciprocating said support, a retractable stop, means mounting said stop for movement between a retracted position beneath said upper surface and within said periphery of said support and a projecting position at one edge of said periphery and above said upper surface of said support, power means mounted beneath said support for shifting said stop between said positions, and said means mounting said retractable stop includes a pivot pin and an elongated slot connection whereby movement of said retractable stop is a combined sliding and pivotal movement.
Claim 9
Dependent Claim
102 words
In combination with a support having an upper surface and a periphery, means for vertically reciprocating said support, a retractable stop, means mounting said stop for movement between a retracted position beneath said upper surface and within said periphery of said support and a projecting position at one edge of said periphery and above said upper surface of said support, power means mounted beneath said support for shifting said stop between said positions, and said means mounting said retractable stop includes a pivot pin and an elongated slot connection whereby movement of said retractable stop is a combined sliding and pivotal movement.
Claim 10
Dependent Claim
26 words
The combination of claim 7 wherein said support includes means defining said slot, and said pivot pin traverses said slot and moves along the length thereof.
Claim 11
Dependent Claim
46 words
The combination of claim 7 wherein said stop is part of a generally T-shaped member defined by a cross arm and a leg projecting generally medially thereof, said leg carries said pivot pin, and said pivot pin traverses and moves along the length of said slot.
Claim 12
Dependent Claim
73 words
The combination of claim 7 wherein said stop is part of a generally T-shaped member defined by a cross arm and a leg projecting generally medially thereof, said leg carries said pivot pin, said pivot pin traverses and moves along the length of said slot, and one end of said cross arm is moved from a generally horizontal position to a generally vertical position upon motion of said pivot pin along said slot.
Claim 13
Dependent Claim
23 words
The combination as defined in claim 10 wherein said leg carries said pivot pin and said pivot pin is disposed within said slot.
