Abstract: An intensifier for delivering ultra high pressure water to a cutting head of a water jet cutting apparatus. The intensifier has a power piston and cylinder assembly connected to piston members extended into pumping chambers in housing located at opposite ends of the piston and cylinder assembly. Inlet poppet valves located in the pumping chambers control the flow of water from inlet passages into the pumping chambers. Outlet poppet valves allow ultra high pressure water to be pumped out of the pumping chamber into an accumulator fluidly connected to the cutting head. Hydraulic fluid under pressure is sequentially directed to opposite ends of the piston and cylinder assembly with a solenoid operated reversing valve. Limit switches operable in response to movement of the piston members control the reversing valve. Linear motion transfer mechanisms are moved with ramps on the piston members to actuate the limit switches to control the reciprocating action of the piston and cylinder assembly.

Abstract: An ultra high pressure water tool has a nozzle assembly equipped with a fan tip that discharges a relatively flat stream of ultra high pressure water to a surface to remove coatings and flashings. The fan tip has a body containing an elongated passage and a layer of super hard material having an elongated discharge orifice open to the passage.

Abstract: A cutting head for a water jet cutting machine has a body removably supporting a holder with an orifice element, and insert with a chamber, and a nozzle having a passage in alignment with the water flow path through the head. The holder has a cone shaped surface that fits into a complimentary shaped cone recess to align the aperture of the orifice element with the axis of a water inlet chamber. The insert is retained within a transverse bore in the body to align its chamber with the axis of the aperture. A griping collet holds the nozzle on the body and aligns the passage of the nozzle with the axis of the aperture so that aperture, insert chamber, and the passage of the nozzle are linearly aligned with each other to form the water flow path through the nozzle.

Abstract: An abrasive liquid jet cutting system has a cutting head for directing a jet of ultra high pressure water and grit to a work piece. The jet cuts the work piece in a desired pattern to form a product. The liquid from the jet, grit, and particulate materials of the work piece are collected with a receiver located generally below the cutting head. Controls for both the cutting head and receiver are coordinated to move the receiver along with the cutting head so that the water and particulate materials are collected by receiver. The receiver has an upright tubular member provided with wear resistant sleeves and an upright central rod to absorb the impact forces of the water and particulate materials that move through the receiver. A drive means connected to the tubular body operates to continuously rotate the tubular body, sleeves and rod to distribute the wear around the sleeves and rod caused by the water, grit and particulate materials that impinge thereon.

Abstract: A machine and method for winding coils of wire on a slotted core of an armature assembly. The machine has a holder for releasably supporting the armature core assembly in an upright position. Rotatable annular members located adjacent opposite sides of the core have holes for accommodating wires that are wound on the core. Chucks mounted on the annular members guide the wires moving from the annular members into two pairs of slots in the core. A motor connected to the annular members with a common drive structure rotates the annular members in opposite directions to wind two coils of wire on the core. A core indexing motor drivably connected to the holder operates to sequentially index the core during the winding operation.

Abstract: An automatic conveyor system wherein identical carriers that have coaxial circular and non-circular surfaces and axially oriented pockets to receive articles to be moved from one work station to another, roll along track sections that connect the several work stations and, upon arriving at the successive work stations, are presented thereto in predetermined rotary orientation established by coaction between a surface thereof that is part of their non-circular portion, and an adjacent track section. At certain of the work stations the carriers enter transfer mechanism by which the carriers are tipped from axially horizontal to axially vertical disposition and back to the horizontal orientation.

Abstract: An automatic armature production line comprising an assembling machine by which the component parts of an armature core assembly are assembled, a bank of armature winding machines by which the armatures are wound, a welding machine by which the wire leads connecting successively wound coils are physically and electrically connected to the terminals of the commutator, a testing station at which the completed armatures are tested for electrical continuity, and a transfer system by which the armature core assemblies and then the wound armatures are quickly moved from one work station to another, the transfer system comprising a plurality of identical cylindrical carriers that have axial cavities into which the armature core assemblies and the wound armatures are inserted and which roll along downwardly inclined tracks that lead from station to station, and which carriers have a flat surface spaced from their axes of rotation to coact with flat surfaced guides at the different work stations to hold the carriers i

Abstract: An apparatus for winding coils of wire on the core of an armature having a pair of rotatable wire winding members rotatably mounted on first and second housings. A first pair of plate beam assemblies yieldably mounts the first housing on the support. A second pair of plate beam assemblies yieldably mounts the second housing on the support. The plate beam assemblies locate the wire winding members in wire winding positions adjacent the core of the armature. A control unit connected to each housing is operable to move the housings to selected positions by flexing the plate beam assemblies. The control unit has a fluid motor and linkages that are operable to move the housings and wire winding members away from the core so that the wound armature can be removed from the apparatus.

Abstract: An armature winding machine having an indexing mechanism for indexing the armature. The indexing mechanism includes an indexing clutch driven by an electric motor. A gear drive connects the clutch to the holding structure for the armature. The indexing clutch has a control collar that is selectively engaged with a plurality of pawls operable to stop the control collar at predetermined precise rotational positions. The positions of the pawls relative to the control collar are individually adjustable on a support providing for selective adjustment of the indexing positions of the clutch.

Abstract: An applicator by which small, discrete, uniform quantities of molten thermoplastic adhesive can be dispensed in rapid succession comprises a body having a heated inlet chamber, which hot melt enters under low pressure, and a pump chamber. A plunger in the pump chamber is reciprocated by a pneumatic motor. A charging stroke of the plunger draws hot melt out of the inlet chamber, across a check valve and into the pump chamber. The discharging stroke expels the hot melt across an outlet check valve and through an outlet orifice coaxial with the pump chamber.
