Abstract: An apparatus for mechanically limiting a plurality of switch type circuit breakers mounted in linear alignment so that a predetermined number of circuit breaker switches can be in a predetermined position at a time, generally ON, and whereby access to all remaining switches is prevented and the unintentional operation of all remaining switches is prevented. A rigid housing is provided for mounting a plurality of switch-type circuit breakers in linear alignment. An interlock plate is slidably mounted to the housing adjacent the breaker switches. An opening through the interlock plate allows access to the predetermined number of switches which are to be accessible. The solid portion of the cover prevents access to the remaining switches and locking bars on the bottom face of the interlock plate mechanically limit movement of the remaining switches. In order to move the interlock plate to access other breaker switches, all switches must be in the same position, generally OFF.

Abstract: An enclosure (10) is provided for storing a battery (12) or other device that emits hydrogen or other potentially explosive, lighter-than-air gas during operation. The enclosure includes a floor (14), ceiling (16) and side walls (18) defining a substantially air-tight interior space, and a ventilation system for venting the low density gas from the space. The ventilation system includes a first passageway (20) extending through the side wall (18) into an upper end of the space and including an inlet (24) disposed in the interior space at the upper end and an outlet (26) disposed outside the space. Also, the system includes a second passageway (22, 42) that extends into a lower end of the space, terminating at an outlet disposed within the enclosure adjacent the upper end of the interior space.

Abstract: In a system for flocking a substrate, such as a garment, the improvement comprising a method, apparatus and article for adjustably controlling the moisture content of the flock in the flock tray to any desired moisture level, whereby the flocking machine is not limited to use only in a plant having a humidity controlled atmosphere.

Abstract: A flocking system including a cabinet supporting a substrate to be flocked and a flock tray, means for raising and lowering the flock tray into and out of contact with the substrate (such as a garment), and means for sealing the moving flock tray to the cabinet to prevent flock from getting into the cabinet to prevent contamination of the mechanics of the internal portion of the cabinet by flock. The flock tray includes a slowly rotating rotor for keeping the flock agitated, a telescoping shaft connecting the rotor to the motor, a flock tray holder for maintaining the seal with the cabinet, and a flock tray cover with one or more flocking masks with various size openings.

Abstract: A garment holding turret system for a flocking machine including spring biased means for holding excessive portions of a garment in place while the adhesive is being applied and during the flock cycle. The turret has no protuberance at the chest or stomach of the operator to hinder the operator's movements in placing a garment on the turret or during the screen printing operation. The turret can be rotated in one direction for setting up the machine or making adjustments without activating the high voltage and can be rotated in the other direction to activate the high voltage for the flocking operation.

Abstract: A method and apparatus for applying flock to a substrate, such as a garment, comprising a compact, portable, self-contained flocking machine in which the cabinet and flocking trays are non-metallic and are preferably wood and plastic, respectively, whereby the electric field from an electrode in the flocking tray to the metallic garment holding platen causes the flock to move in a straight, uniform, dense pattern from the flock tray to the garment. In addition, the high voltage electrode in the flock tray is not energized until the flock tray has moved up and made contact with the garment holding platen to prevent flock from coming up out of the tray while the tray is moving up and down and to prevent any risk of shock to the operator. The platen is mounted on a rotatable shaft and diametrically opposed to a similar platen in an uppermost position which is operatively associated with a screen printer. In use, a printed substrate is flocked while an additional substrate is being printed.

Abstract: A jacket type of garment is provided with a storage or back pack secured to and made part of the garment in such a way that the load of the pack is suspended from a pair of shoulder straps carried within the garment. Upper and lower corners of the storage pack are secured to the straps to distribute load forces from the storage pack to the straps and not to be seams of the jacket, and also to prevent lateral shifting of the lower end of the back pack when it is loaded.

Abstract: A method and apparatus for making flocked heat transfers such that, when the resultant flocked heat transfer is applied to a receiving surface such as a garment, no objectionable thermoplastic deposit is left on the garment in the background areas of the flocked graphic design. The method comprises applying the flocked pattern onto a thermoplastic film carrier, placing an open mesh carrier cloth on top of the flocked pattern and film, and then applying a vacuum behind the cloth carrier while heating the sandwich structure to draw the heat softened thermoplastic film deep into the fibers of the carrier cloth of the heat transfer. The carrier cloth has a weave and absorbency so as to accept the thermoplastic material and retain it when the flocked heat transfer is finally applied to a receiving surface such as a garment, so that none of the film transfers to the garment in the background areas.
