Abstract: A staple fastener applying machine comprises a base on which is mounted a first support that pivotally supports a driver arm carrying a driver and a holder arm holding a staple magazine, the driver arm being actuatable for angular movement toward the base by a solenoid mounted on the base so as to force the driver toward a clinching anvil carried on a second support mounted on the base. Staple fasteners stored in the magazine are fed one at a time into the path of movement of the driver for being driven thereby. The solenoid is located remotely from the second support to provide a relatively large space around the second support such that the machine can handle a relatively bulky object for staple applying operation. The driver and holder arms are spring-biased away from each other, but are prevented from moving apart beyond a certain angular spacing between them.

Abstract: A heating cylinder with a chamber therein is mounted on a base and has a discharge nozzle with an orifice therein, a plunger being movable into the chamber toward the discharge nozzle. A mold holder is supported on the base and has a mold including first and second mold members which jointly provide a mold cavity therebetween. The mold holder is pivotable between a first position in which the mold is held in contact with the discharge nozzle with a sprue in one of the mold members being held in communication with the orifice and a second position in which the mold is located away from the discharge nozzle. There is a means on the base for locking the mold holder in the first position.
