Abstract: A cone drive, high output speed reducer, having a low clearance for low profile applications. An input shaft drives a helical idler pinion which in turn drives two other helical idler pinions. The two other idler pinions are each mounted on a separate shaft carrying a cone drive worm. The two worm shafts turn in unison, and the worms are each meshed with a separate worm gear. The two worm gears are operatively mounted on an output shaft. One of the helical idler pinions is provided with an adjustment means for equalizing the load sharing. That is, to provide equal loads on each of the helical pinions for load sharing throughout the twin drive gearing units of the speed reducer. The speed reducer may be provided with either an air cooling system or a water cooling system.

Abstract: A roll-through cold forming apparatus adapted to form simultaneously a plurality of either external or internal straight spline or gear type teeth on a cylindrical workpiece carried on a movable ram. In one embodiment the apparatus includes a plurality of radially disposed pivotally mounted teeth forming blades which are disposed around the axis of movement of a linearly movable ram, whereby when the ram moves in one direction past the teeth forming blades, the blades are engaged by an interference contact with the workpiece carried on the ram, and the teeth forming blades are moved over the external surface of the workpiece in a rolling contact action so as to displace the material of the workpiece between each tooth forming edge of each of the blades. The material on the external surface of the workpiece is formed around the radius of each of the tooth forming edges of each of the forming blades on a line with the configuration of each tooth forming edge.

Abstract: A method for assembling sheet metal pipes, and a machine for carrying out the method which comprises assembling a pipe from a preformed pipe blank into a finished pipe without permanently deforming the pipe blank material. The method comprises the steps of folding of a preformed pipe blank, having a male lock joint member along one longitudinal edge and a female lock joint member along the other longitudinal edge so as to move the longitudinal edges toward each other, and then inserting the male lock joint member into the female lock joint member, with the spring tension created in the pipe blank due to the folding action effecting a locking action between the two lock joint members.

Abstract: A machine tool high speed spindle assembly and draw bar assembly, wherein the spindle assembly includes a hollow, rotary spindle shaft, and the draw bar assembly is nonrotational relative to the spindle shaft. The draw bar assembly is axially movable within the hollow rotary spindle shaft, and it includes a tool holder gripping means. The draw bar assembly rotates with the hollow rotary spindle shaft during a machining operation. The draw bar assembly with its tool holder gripping means is moved by an actuator means between an operative position for retaining a tool holder or the like in the spindle shaft, and an inoperative position to permit a tool holder or the like to be removed from or inserted into the spindle shaft. A spindle shaft holding or gripping means retains the hollow rotary spindle shaft in a stationary position when the draw bar actuator means moves the draw bar assembly between said operative and inoperative positions.

Abstract: A carton bottom breaker for performing a prebreaking operation on the panels of a bottom closure structure of a coated paperboard carton mounted on a carton forming mandrel. A movable carrier member has a V-shaped breaker means fixed thereon which comprises a pair of outwardly sloping folder plates for operative engagement with the fold-over panels of the bottom closure of a carton. A spring biased V-shaped breaker plate member is movably mounted on the carrier member between the sloping folder plates in a plane transverse to the V-shape formed by the folder plates, and it is adapted to engage the fold-in panels of the bottom closure of a carton. A mandrel stop finger is carried by the V-shaped breaker plate member for abutment with the carton mandrel, in an off-center position, to prevent damage of the mandrel by engagement with the V-shaped breaker means and V-shaped breaker member.

Abstract: A tool holding assembly wherein a self-locking chuck or tool holder is releasably secured in a rotary spindle by a draw bar and collet type tool holder gripping means. The self-locking chuck is provided with a spring-biased, ball locking means that functions as a safety retainer means for holding the chuck or tool holder in the spindle in case of a breakage of the collet type tool holder gripping means. The spindle is provided with a tapered seat against which the balls of the ball locking means are normally urged by a spring biased plunger that is movable to a ball unlocking position by the draw bar.

Abstract: A carton jam detector means for use on a carton loader apparatus in a carton packaging machine. The loader push rod has mounted thereon a carrier block which has fixed thereto a valve body having pressurized air passages formed therethrough. A carton lifter finger is pivotally mounted on the valve body and is provided with a vent valve adapted to normally close a valve seat or orifice at one end of said air passages, so as to prevent flow of pressurized air through the air passages. If a carton jam occurs, the lifter finger, which is normally held by a detent means in a position to keep the valve vent closed, is then pivoted by the resistance of the jam to override the detent means and allow air to vent through the open air orifice. The pressure drop in the air flow system is monitored by a system of suitable controls for stopping the loading of cartons until the jam is corrected. The rest of the packaging machine may continue to process the cartons already loaded into the machine.

Abstract: A water cannon adapted for controlling large crowds of unruly people in a highly effective, yet non-lethal fashion. The cannon can be mounted on an appropriate vehicle, such as an armored car, so as to make it mobile and its supporting system completely self-contained. The water cannon discharges a high velocity stream of water in a pulsing fashion. Each pulse forms a water projectile which is effective against human targets at ranges up to one hundred feet. The water can be treated with a variety of desired additives. The water cannon includes a cannon body on which is operatively mounted a nozzle for discharging the discrete coherent water projectiles. The discharge of the water projectiles is controlled by a main stage valve, which is in turn controlled by a pilot valve. A water supply reservoir and pump are provided for supplying water under pressure to the main stage valve.
