Abstract: The method and apparatus for the injection of an injection material into a mold includes an upright extruder mechanism having an upright feed screw driven from its lower end. Material introduced at the top of the extruder is fed by the screw outwardly of the extruder through an outlet projected laterally outwardly from the extruder at a position adjacent the lower end of the screw. The extruder outlet constitutes a piston receivable with a cylindrical material chamber of an injection nozzle unit. Material is fed in one direction in incremental amounts from the extruder and into the material chamber when the extruder is moved in one direction relative to the injection nozzle unit, and is then forced from the material chamber by the extruder outlet and into the nozzle unit for injection into a mold when the extruder is moved in an opposite direction relative to the nozzle unit.

Abstract: The bale feeding attachment is mountable on a machine for handling large round bales that has a vertically adjustable elongated main frame including a pair of transversely spaced side structures, each of which has a longitudinal ramp member. The ramp members are movable with the frame to lowered positions at opposite side portions of a ground supported bale and engageable, on elevation of the frame, with the bale side portions to support the bale for transport. The attachment includes a pair of laterally extendible and retractable bale supporting units, each of which, when retracted, is pivotally movable on an associated side structure to an inoperative position permitting a normal use of the bale handling machine. When a bale is in a transport position, between the supporting units, the supporting units are pivotally moved and laterally extended to move bale feeding rollers thereon into bale holding positions, free of the machine ramp members.

Abstract: The hydraulic power system includes a single electrical motor for driving a fluid pump which supplies fluid under pressure to a plurality of series connected fluid motors, with the first motor in the series directly to the pump outlet and the last motor in the series to a fluid reservoir that constitutes the fluid source for the pump. The electrical motor is operable in response to a call for the actuation of any one of said fluid motors, and requires a maximum power output relative to the pump fluid capacity so that the fluid pressure and flow characteristics delivered by the pump satisfy the full load operating requirements of the last fluid motor in the series of motors when all of the other fluid motors are under full load operation.

Abstract: The golf ball receiving apparatus includes a net structure for enclosing a liquid filled container having a flexible front wall facing an open side of the net structure and constituting a ball target. The impact force applied on the front wall displaces liquid within the container in volume amounts proportional to the magnitude of the impact force. The displaced liquid is confined for movement into an accumulator chamber associated with an operator member, movable in response to the volume of displaced liquid, and directed to actuate a transfer member which transmits the magnitude of the impact force to a drive indicating gauge or scale. After striking the target, the driven balls are directed into a receptacle that is manually movable to deliver the balls to a collection area for reuse or for feeding into a practice driving machine.

Abstract: A luminaire ballast mounting means for mounting ballast in a housing having a flat side wall includes a pair of linear rods that extend through a corresponding pair of openings arranged in a spaced relation along one side of the ballast. One pair of adjacent projected rod end sections is received within and in bearing engagement with a support member secured to the housing side wall and the other pair of projected rod end sections is engageable with a clamping means carried on the housing side wall and operable to move the other pair of rod end sections toward the side wall. When thus moved, the rods are flexed between the support member and clamping means to positions wherein the ballast is clamped against the housing side wall.

Abstract: The canal paving machine has an elongated main frame supported in an elevated position on a pair of end frame structures each of which includes an upper mounting section, a lower traction section and an intermediate connecting section. One mounting section is movably supported on the main frame for movement longitudinally thereof to vary the longitudinal spacing between the end frame structures. Each traction section has front and rear traction units movably connected together to vary the spacing therebetween transversely of the main frame. The connecting section is vertically adjustable relative to the traction section and the upper mounting section is vertically adjustable relative to the connecting section. During a paving operation the upper sections are retracted relative to the connecting sections and the main frame adjusted relative to the ground surface by vertical adjustment only of the connecting sections.

Abstract: The locking mechanism holds a reel spindle against rotational and axial movements at all times during the loading and transport of a cable reel. Each pivoted lift arm of the reel handling apparatus is of a tubular construction and formed at its free end with a spindle receiving pocket within which the reel spindle is locked against movement by being clamped into frictional engagement with portions of the pocket. The locking member is movably supported within each lift arm and has a jaw portion retractable within an arm to open the pocket. A power unit for actuating the locking member is enclosed within an associated lift arm.

Abstract: Separable mold sections of a tire forming machine are brought together to form a tire cavity within which a preformed tire band is expandable against the inner surface of the cavity side wall. During the tire shaping operation, air is forced by the expanding tire band from the cavity and into the atmosphere, through valve controlled air passages having terminal ends open to the cavity side wall. As the expanding tire band moves into conforming engagement with the inner surface of the cavity side wall, the final residual air in the cavity is forced therefrom concurrently with valves at the passage terminal ends being engaged and moved by the expanding tire band to passage closing positions wherein the valves form a smooth surface continuous with the inner surface of the tire cavity.

Abstract: The method and power transmission system of this invention for driving a road planar machine has the cutter unit in a positive mechanical drive with the drive shaft of a machine power unit through a hydraulically actuated clutch mechanism. The wheel traction units for the machine are continuously driven from the power unit by hydraulic motors operated by variable volume displacement pumps. A control system for retaining the power unit at a set rotational speed required for a predetermined cutting or planing load is responsive to a drop in the set rotational speed, resulting from the cutting unit encountering an overload, to actuate the variable displacement pumps to decrease the forward speed of the machine without appreciably reducing the rotational inertia force of the cutting unit. If the cutting unit overload is of a short duration or momentary the set rotational speed of the power unit is resumed.

Abstract: The cylindrical shaped helically wound storage bin is comprised of a roof unit and a side wall structure each of which is separately formed and assembled together in the field. The wall structure and the roof unit are each formed from a continuous metal ribbon member. The ribbon member of the roof unit is helically wound and continuously interlocked in a stepped dome shape with the interlocking connection of the adjacent sides of the metal ribbon constituting riser portions of the steps and a reinforcing member for the roof unit. The metal ribbon of the bin wall structure is helically wound and continuously interlocked along the adjacent sides thereof in a cylindrical shape with the interlocking connection forming a continuous rigid reinforcing rib that projects outwardly from and extends spirally about and over the full height of the side wall structure.

Abstract: The cable reel handling apparatus is mountable on a truck and operable to separately lift and move a pair of reels from ground supported positions rearwardly of the truck to transfer positions substantially centered relative to the truck rear wheel and axle assembly and between side compartment units that project above the truck bed and extend longitudinally over the length of the bed. A carriage structure is movable on tracks located above the side compartment units between a forward reel transport position and a rearward reel loading position in which the first reel to be transported is directly transferred by vertically movable lift arms mounted at the rear end of a vehicle to an axle supported position on the carriage structure for movement therewith to the forward reel transport position.

Abstract: A knife of a pencil type includes a barrel or outer member in which a slidably carried support or inner member is connected in an end-to-end relation with a blade assembly for movement of the blade assembly to extended and retracted positions relative to one end of the barrel member. The blade assembly includes tension fingers that extend from a lower portion of the blade assembly periphery to engage the barrel member and bias such member in an upward direction thereby preventing side-to-side play of the blade assembly in the barrel member and to inhibit upward movement of the blade assembly therein. The blade assembly is also formed with a slight bow to urge the upper portion of the blade assembly against the barrel member and thereby prevent undesired upward movement of the blade assembly when a cutting operation is performed.

Abstract: The bale handling attachment is adapted to be pivotally mounted on the pivoted vertically movable lift arms of a usual tractor three-point hitch and includes a pair of tine members that have limited downward pivotal movement, relative to the lift arms, to positions extended longitudinally of the lift arms. When the lift arms are lowered, the tine members are pivotally movable upwardly, relative to the lift arms, to horizontal ground engaged positions for following the ground contour to locations at opposite sides of the bottom portion of a bale to be handled. An upright push plate has the bottom edge thereof rideable on the upper surfaces of the tine members, and is movable from a rest position at the inner ends of the tine members, to a bale unloading position adjacent the outer ends thereof to provide for bales being stored in a double tier, one on top of the other.

Abstract: An assembly for mounting the shank of a ground tool to a clamping plate carried on the tool bar of a soil tilling farm implement. The mounting assembly has a mounting member for attachment to the clamping plate, a first pivotal connection of the tool shank with the mounting member, and a variable pressure unit associated with the tool shank and the mounting member for applying a variably decreasing pressure on the ground tool during movement thereof from an operating position to an inoperative position. The pressure applied by the variable pressure unit, in a first moved position therefor, acts to initially hold the ground tool in the operating position, and in a second moved position being rendered ineffective to return the ground tool to the operating position.
