Abstract
An axially elongated tube is slideably and pivotally supported within a tlar housing from which the tube extends rearwardly for connection to a source of vacuum. The vacuum is selectively applied through the tube from a flattened forward end thereof to a workpiece after the tube is slideably displaced rearwardly from a retracted to an extended position within the housing. A hand grip on the housing enables it to be manually held in operative relation to the workpiece. A support assembly pivotally mounted on the housing adjustably positions a heating jaw electrically connected by a switch on the housing to a power supply for performance of heat sealing operations on the workpiece.

In combination with a source of vacuum and an electrical power supply, apparatus including a switch and heating jaw means connected by wiring under control of the switch to the power supply for performance of heat sealing operations on a workpiece to which the vacuum from said source is applied;
- a portable housing;
- and means mounting the jaw means on the housing for adjustable positioning thereof, wherein the improvement comprises:
- an elongated tube within the housing through which the vacuum is applied to the workpiece;
- and means supporting the tube within the housing for slideable and pivotal displacement relative to the heating jaw means to effect said heat sealing operations while the portable housing is held in operative relation to the workpiece.

- a portable housing;
- and support means pivotally mounting the jaw means on the housing for adjustable positioning thereof, wherein the improvement comprises;
- an elongated tube within the housing through which the vacuum is applied to the workpiece;
- and bearing means supporting the tube within the housing for slideable displacement relative to the source of vacuum and pivotal displacement relative to the heating jaw means.
Apparatus for heat sealing a workpiece, comprising;
- an elongated nozzle tube having a flattened end portion;
- a pair of heating jaws;
- a housing on which said heating jaws are adjustably mounted;
- bearing means supporting the nozzle tube for slidable displacement within the housing between retracted and extended positions in which the jaws are electrically heated and the nozzle tube is connected to a vacuum source, respectively;
- and means for pivotally displacing the flattened end portion of the nozzle tube in the retracted position thereof between the heating jaws while disconnected from said vacuum source.
