Abstract: An internal combustion engine having a rotating crankshaft mounted on at least one main bearing is provided with an oil pump having at least one gear surround the crankshaft and rotationally driven by the crankshaft. The pump gear surrounds the main bearing so that the main bearing and the oil pump occupy a common axial space on the crankshaft.

Abstract: A water pump drive mechanism for an evaporative cooler which includes a blower housing, a blower shaft extending therefrom, a pulley fixed on the shaft, and a water pump; the drive mechanism having an elongated tube mounted on the housing extending from the pump toward the pulley, a drive shaft extending longitudinally of the tube and rotationally mounted thereon having a lower end rotationally engaged with the pump and an upper end adjacent to the pulley, and a friction wheel mounted in the upper end of the drive shaft engaging the pulley for rotational drive of the water pump from the pulley.

Abstract: Attic fans and apparatus for supporting the drive motors of attic fans, the attic fans being of the type having a housing connected around the sides of a rectilinear aperture through a wall, usually the ceiling of a home or building, the housing having a circular opening within which radially disposed fan blades mounted on a central shaft are rotated. In the attic fan shown herein, the blades are supported between spaced plates rotatively carried on the shaft. The shaft is supported at its lower end by a plurality of radially disposed supports, and is supported at its upper end by a single radial disposed support. The drive motor is supported at one side of the circular opening through the housing by a rod extending from the upper radial support to the housing. A support plate element pivotally connected to the rod has upper and lower inturned portions which engage the motor.

Abstract: A pump assembly to be used for mining, and the like, is supported on rope-like members (32, 110, 112, 140, 181,190) of an endless conveyer. In one type of embodiments a channel-shaped mounting member (20, 72, 138, 164, 192) of the pump assembly straddles the rope-like support members and allows the weight distribution of the pump assembly to cause a drive wheel (16, 68, 142, 146, 196) of the pump assembly to come into contact with the endless conveyer (28, 144, 198) to thereby drive a pump (18, 76, 134, 160, 182) of the pump assembly. In a particular one of these types of embodiments the pump (134) is mounted inside the rope-like support member (140) to urge the drive wheel (142) downwardly against the return portion (144) of the endless conveyer and in other particular ones of these types of embodiments the pump (18, 76, 160) is located outside the rope-like support member (32, 181, 164) so that the drive wheel (16, 68, 146) is urged upwardly against the conveying portion (28) of the endless conveyer.

Abstract: A combined pump and generator arrangement for use in a vehicle having an engine as the prime mover is disclosed and includes a pump housing with an axially extending actuating shaft and a rotatable member to be driven by the engine to rotate about that actuating shaft with the rotatable member including a fan and a pulley as well as a magnetic arrangement for providing a rotating magnetic field when the rotatable member is driven by the engine. An annular stator assembly is fastened to a face of the pump housing and has windings for providing a voltage in response to the rotating magnetic field. The actuating shaft and annular stator assembly are concentrically disposed with the stator assembly lying intermediate the actuating shaft and the magnetic arrangement of the rotor. The pulley, stator and magnetic arrangement and the fan are supported progressively more remote from the pump housing face.

Abstract: Attic fans of improved and economical design, wherein the blade hub, which in conventional attic fans is a cast hub is eliminated, and wherein the pulley on the blade shaft is eliminated.

Abstract: Apparatus for housing a centrifugal fan and providing an enclosure for coupling into a ducting network, wherein the fan and driving motor is mounted on a honeycomb-style base which is slidable into and out of the enclosure, and which has an angled edge lip for engaging against a mating edge lip on the enclosure for providing a hinge means for pivotally supporting the fan and motor assembly.

Abstract: A pumping system for dispensing controlled and variable amounts of fluids in predetermined quantities includes a pump piston which moves axially in a pump chamber. The piston is reciprocated by a drive lead nut cooperating with a non-rotatable lead screw attached to the piston. The piston is sealed to the pump chamber by a seal element whose distance from the lead nut is fixed regardless of the position of the piston, thus protecting the seal. The rotatably driven lead nut includes a hollow driven shaft, containing lubricant, so that the lead screw is lubricated as it travels into the shaft of the lead nut. The motor for the system is a pulse operated reversible stepping motor enabling accurate output from the pump, for example, between .01 ml/min to 9.99 ml/min as controlled by the stepping motor. One motor may drive two pumps for a continuous controlled pumping system. If desired a flush mechanism may be used to rinse the piston of any pumped material which adheres to the surface.

Abstract: Disclosed is a bracket providing a housing through which a vertical shaft extends, the shaft being journalled for rotation in bearings carried by the housing. The lower end of the shaft extends into driving relation with a well pump from which the conventional electrical drive motor has been removed. Arms extending sidewardly from the housing are adapted to support an internal combustion engine having a vertical output shaft. A belt and pulley drive connect the output shaft and the pump drive shaft, with the belt extending within the space bounded by the sidewardly extending arms.

Abstract: A hydraulic retarder for braking a shaft has a rotor comprising a rotor shell mounted on the shaft end and rotatively movable relative to a stator shell forming part of a stator enclosing the rotor. The shaft end projects from a housing upon which the stator is mounted by an apertured structure surrounding a driving pulley mounted on the shaft end. The apertured structure comprises lugs on the housing and a toothed ring on the stator, the teeth in the ring co-operating with the lugs so as to hold the stator centred on the axis of the shaft end irrespective of the angular position of the stator. Recesses between the teeth of the ring are disposed and dimensioned so that they provide the necessary openings for moving an endless belt into or out of the structure simply by moving the stator through an angle.
