Abstract: A punch and press system includes a low voltage safety circuit and a high voltage control circuit. The high voltage control circuit is further divided into a high voltage low current region and a high voltage high current region. The high voltage low current region is isolated from both the low voltage safety circuit and the high voltage high current region of the control circuit. As the upper tool of the press strikes an object, the object's conductivity will govern whether the press will continue to act on the object. Thus, if the object is conductive, then the upper tool will continue to act on the object. If the object is not conductive, then the upper tool will raise to a neutral position.

Abstract: A wiper assembly for surface maintenance vehicles has a non-destructive failure mode when impacting stationary objects, or otherwise becoming subject to instantaneous or rapidly increasing resistance to forward movement, due to an improved mechanical coupling. The improved mechanical coupling for a wiper assembly absorbs some of the impact stresses imparted to the wiper assembly. Portions of each improved mechanical coupling designed to absorb the stress forces deforms most nearest the location of increasing resistance to forward movement, and may either become fully disconnected if the stress force reaches a threshold force value or recoils to the original mounting location after absorbing forces that are less that said threshold force value. The threshold value force at which a wiper assembly dislodges from its mounting location is designed to avoid damage to the wiper assembly, the articulated mounting member (if any), and the maintenance vehicle itself.

Abstract: A cycle of operation of an attaching apparatus begins with determining whether an operator's extremity is in an area in which it can be struck by a downwardly moving ram during attachment of two fasteners to each other and to a material therebetween. If it is determined that the operator's extremity is not in the area in which it can be struck by the downwardly moving ram, the remainder of the cycle of operation is completed. If it is determined that the operator's extremity is in the area in which it can be struck by the downwardly moving ram, the cycle of operation must begin again.

Abstract: A fastener-assembling apparatus has a safety device including a vertically movably safe-confirmation member which is normally disposed in its lowermost position in which the gap between the safe-confirmation member and a die is substantially equal to the thickness of a garment fabric. In its lowermost position, the safe-confirmation member maintains a limit switch closed to continue a power supply to a drive for a punch. When the operator's finger or a tool is inadvertently inserted into the gap between the safe-confirmation member and the die, the safe-confirmation member is raised to open the limit switch to discontinue the power supply to the punch.

Abstract: A press comprising a frame with an anvil support and a punch carrier, the latter being mounted on the frame so as to be movable between two ends of travel towards and away from the anvil support. A piston and cylinder arrangement is arranged to act on the punch carrier to urge the latter in a direction towards the anvil support. That one of the two ends of travel of the punch carrier which iscloser to the anvil support is defined by a part or parts of the press itself. A limit switch is operable by means of the motion of the punch carrier, or a part connected thereto, in the said direction when the remaining available travel is a distance which is less than the thickness of an operator's finger, to enable the piston and cylinder arrangement to act on the punch carrier with a working force in the said direction up to the end of its travel.

Abstract: A device for pulling up the slider of a slide fastener chain includes a pair of slider gripping fingers provided in opposed relation, one on each side of a slider guide groove formed in a slide fastener chain guide. The slider guide groove constitutes part of a slider passageway through which a slide fastener having a slider mounted thereon is capable of being passed and guided. The fingers are operatively associated with each other and coupled to an actuating mechanism which thrusts the fingers into the passageway to grip a slider and pull the slider up to a predetermined position as the slide fastener chain advances through the passageway, and which then withdraws the fingers from the passageway to release their grip on the slider so that the slider may pass through the passageway with the rest of the travelling fastener chain.

Abstract: The present invention relates to a safety device for an upper die arbor of a fastening machine having a driving sleeve, an upper mold mandrel, a copper sleeve, and a steel sleeve. The driving sleeve has a roller in each of four holes. A flange is formed on the circumference of upper mold mandrel. Due to the positions of the rollers with respect to the flange, and the difference between inside diameters of quadrangular slots formed in the copper sleeve and steel sleeve, when the upper mold mandrel moves downward and is blocked by an undesired object, the rollers pass over the flange and do not exert the normal forming force on the upper mold mandrel. Therefore, the upper mold mandrel does not exert the mechanical crushing force in order to prevent injury to the object.

Abstract: A slider holding apparatus comprises a support vertically slideable on a base for supporting a slider upside down with a pull tab received in a slit of the support, and a lever having a locking projection and pivotable on the base between a slider-holding position in which the locking projection projects into the slit to lock the pull tab and a slider-release position in which the locking projection is retracted out of the slit to unlock the pull tab. The support is normally urged upwardly by a first spring, and the lever is normally urged by a second spring to the slider-release position. The apparatus further includes means for detecting when the support as depressed against the bias of the first spring arrives at a predetermined lower position, and means, responsive to detection of the arrival of the support, for driving the lever to the slider-holding position against the bias of the second spring.
