Abstract: A mechanical drive mechanism of the endless belt and pulley type having an improved belt tensioning arrangement. The shaft of the machine being driven (or that of the driving member itself) is eccentrically journaled with respect to its cylindrical bearing hub and a rigid arm having a first bore therethrough is disposed with the hub of the machine centered in that first bore. Located at the opposed end of the rigid arm is a parallel bore in which the other drive or driven shaft is journaled. Because of the eccentricity between the first shaft and its hub, as the arm is rotated about the hub as a center, the distance between the centers of the driving and driven shafts is increased or decreased, depending upon the direction of rotation of the rigid arm. As such, the tension of the endless belt coupling the drive and driven pulleys can be varied. The construction of the belt and pulley combination lends itself to being completely enclosed in a protective shroud which need not be removed to make the tensioning adjustment.

Abstract translation: 环带和皮带轮的机械驱动机构具有改进的带张紧装置。 被驱动的机器的轴（或驱动构件本身的轴）相对于其圆柱形轴承座偏心地轴颈，并且具有穿过其中的第一孔的刚性臂设置在机器的轮毂以该第一孔为中心。 位于刚性臂的相对端的是平行的孔，其中另一个驱动轴或从动轴是轴颈。 由于第一轴和其轮毂之间的偏心度，当臂以毂为中心旋转时，根据刚性臂的旋转方向，驱动轴和从动轴的中心之间的距离增大或减小 。 因此，可以改变联接驱动轮和从动带轮的环形带的张力。 皮带和皮带轮组合的结构使其完全封闭在保护罩中，不需要将其去除以进行张紧调节。

Abstract: A multi-cylinder pump for delivering fluids under high pressure which includes a multi-lobed camshaft having bearing supported yoke elements disposed in an oil-filled crankcase for coupling the camshaft to plural piston elements such that displacement of the plural piston elements occur in a desired phase relationship and improved sealing arrangements disposed between the piston and the cylinders, between the suction inlet port and the high pressure outlet port and between the cylinders and the oil-filled crankcase to prevent cross-contamination of the oil lubricant and the fluid being pumped and to prevent any substantial leakage between the high pressure outlet port and low pressure inlet port during the suction and pressure strokes of the pistons.

Abstract: A high pressure fluid handling pump of the type having a drive shaft for connection to a drive motor where the drive shaft extends longitudinally through a pulsation dampener affixed to the pump's housing. The pulsation dampener comprises a cup-shaped housing having a pump shaft receiving bore extending through an end wall thereof and which, when secured to the motor housing, defines a hollow chamber in fluid communication with the pump's outlet. Disposed within the hollow chamber of the pulsation dampener housing and concentric with the motor's shaft is a rigid baffle member. Surrounding that is a tubular diaphragm formed from an elastomeric material of a predetermined durometer hardness, the tubular diaphragm effectively dividing the hollow chamber into two compartments isolated from one another. One compartment is exposed to the pressure surges occurring in the fluid being pumped through slits formed in the baffle member and the other compartment is pressurized by a compressible fluid to a predetermined pressure value.

Abstract: Improved multi-cylinder pumps wherein a plurality of co-planar positioned connecting rods are radially disposed about a crankshaft and wherein a plurality of generally cylindrical spool-like wrist pins are rotatively coupled to the connecting rods. The improvement comprises an assembly wherein the wrist pins have opposed end regions bordering a smaller diameter central region that contains one or more ring receiving grooves and which wrist pins are mountable in overlapping relation to retainer ring containing grooves formed in the connecting rods. Upon mounting retainer rings in the connecting rod grooves and inserting and rotatively locking the wrist pins in the connecting rods, the connecting rods, wrist pins and retainer rings are integrally locked together in radially extending relation.

Abstract: Multi-cylinder in-line and radial pumps having an improved structure for coupling the piston heads to the crankshaft such that the number of parts commonly employed and the size of the resulting pump is greatly reduced when compared to prior art pumps now on the market. Both in-line piston pumps and radial diaphragm pumps are included. The connecting rods comprise plates, each having a bore through the thickness dimension thereof for receiving a cylindrical lobe formed eccentrically on the pump's crankshaft. Formed on one end of each of the connecting rods is a generally cylindrical bore, also extending through the thickness dimension of the connecting rod, the center of this bore being displaced inwardly of the end edge surface of the connecting rod by a distance which is less than the radius of the bore. A cylindrical wrist pin having a flat formed on a peripheral surface thereof is insertable into the bore or recess at the end of the connecting rod and when the pin is rotated so that its flat portion is aligned parallel to the end edge of the connecting rod, it is firmly locked in place but rotatable or floating within the recess. A bore formed perpendicular to the flat on the floating wrist pin is threaded to receive a bolt used to fasten the plunger rod to the floating wrist pin. Other features of the pumps of the present invention include a cylinder head designed to receive sleeve inserts of differing sizes whereby pistons of differing cross-sectional areas can be utilized to vary the capacity of the pump, and grooved shoulders on the connecting rods to cooperate with holding rings around the crankshaft.

The pressure seal assembly comprises a generally "U"-shaped cup held between inner and outer retaining discs, and wherein the inner retaining disc is disposed with its inner peripheral edge surface in normal running contact with the surface of the plunger and with the inner disc consisting of polytetrafluoroethylene. The vacuum seal assembly comprises a carbon guide adjacent the inner end of the cylindrical sleeve and an adjacent vacuum seal sleeve formed of polytetrafluoroethylene. The polytetrafluoroethylene sleeve is disposed outwardly of the carbon guide and resilient means are provided for biasing the inner peripheral surface of the vacuum sleeve against the outer peripheral surface of the plunger.

Abstract: A roller pump comprising a generally cylindrical housing and a generally cylindrical rotor disposed eccentrically within the housing, and having push rods arranged radially within the rotor for assisting in forcing radial motion of the rollers within the rotor during rotation of the rotor within the housing. A camming shaft is disposed within the housing, and arranged generally with the housing, the push rods making contact with the periphery of the camming shaft in order to provide radial motion of the push rods during rotation of the rotor. The cross-sectional dimension of the push rods is preferably equal to at least 331/3 percent of the axial length of the rollers, and secondarily preferably having a diameter generally equal to the roller diameter. The cross-sectional dimension of the push rods at the line of contact with the roller surface enables the pump to effectively handle highly viscous products.
