Abstract: Wood golf club heads are first subjected to a vacuum and then immersed in a solution of resin while under a source of vacuum condition. The heads are then subjected to an elevated pressure. The pressure is then removed and the heads dried. Apparatus for effectively carrying out the process utilizes a treatment chamber arranged to receive one or more of the heads. This chamber is associated with vacuum and elevated pressure supply apparatus to selectively subject the chamber to vacuum or pressure. A resin chamber is supported on top of the treatment chamber and has a valved conduit for controlling the supply of resin introduced to the treatment chamber.

Abstract: A screening basket has one or more screen decks and has upright side walls integrated with cross beams. A side beam, at approximately the center of gravity of the basket, is integrated with each of the side walls as well as with the cross beams to provide a unitary, rugged basket capable of vibratory movement on a support frame. A pair of cross shafts extend transversely of the screening basket and project beyond the side walls. These shafts are journaled in the side beams and have one projecting end geared together for opposite rotation. These projecting ends carry semi-circular eccentric weights of different mass to provide an oval vibratory stroke of the screening basket upon rotation of the shafts. Adjusting mechanism is provided to adjust the relative position of the weights on the shafts to vary the angle of stroke. These weights are arranged to receive auxiliary weights to vary the amplitude of vibratory stroke as well as the shape of the stroke.

Abstract: A scale is provided for establishing a swing inertia value of golf clubs by providing support means arranged to contact the grip portion of the club such that the axis of rotation of a person's grip on the grip portion of the club when in the act of swinging the club is disposed vertically above the pivotal axis of a balance beam of the scale. The scale supports a golf club for determining such swing inertia value and includes calibrations which comprise values determined by multiplying the head weight of the club by the length of the club shaft extending from the pivotal axis of the balance beam to the center of gravity of the club head. The scale can also be used to determine the head weight of a club.

Abstract: Oppositely facing surfaces have grooves in one of the surfaces and low coefficient of friction inserts in the grooves. The inserts have a thickness greater than the depth of the grooves so as to project from the grooves when seated therein for bearing against a facing surface and maintaining the two surfaces in spaced apart relation. Such inserts provide a reduced friction relation between the two surfaces whereby the two surfaces can be readily rotated between a working condition having a thrust load therebetween and a loosened non-working condition. Preferably, two or more of the grooves and inserts are provided, the inserts being held in the grooves by distorted portions in the walls of the grooves.

Abstract: A hosel is formed with an upwardly opening socket for receiving a shaft that has a projecting flange with an outer edge. A ball striking plate is manufactured in separate form from the hosel and is secured to the flange in desired positions of loft and other relationships. One or more weights are arranged to be secured to the rear side of the ball striking plate for providing a desired club head weight and center of gravity. A method of the invention includes the steps of forming a hosel and the ball striking plate as separate elements and then shaping and positioning the flange for securing the ball striking plate at the desired angle and position.

Abstract: A base member has a face surface arranged to face a load receiving member. A plurality of grooves are provided in the face surface and bearing inserts are supported in these grooves. Such inserts project beyond the grooves and terminate in end bearing surfaces arranged to be engaged by the load receiving member. Lubrication inlets comprise cross grooves communicating with the insert receiving grooves whereby to supply lubrication under pressure to the area between the inserts. The system is associated with a high pressure source whereby oil is arranged to be forced over the end bearing surfaces of the inserts to provide a hydrostatic support for the loading receiving member. A water cooling passageway is provided in the base member.

Abstract: An upright frame is secured to the base member of a rock crusher and supports a slide bar for horizontal movement. A fluid-operated cylinder is connected between the upright frame and the slide bar for driving the latter longitudinally in both directions, and a pivotal driver is mounted on the slide bar for movement into and out of engagement with projections on the crusher bowl. A second fluid-operated cylinder is connected between the slide bar and the driver for pivoting the latter between an inner engaging position with the projections and an outer release position. By suitable operation of the two fluid-operated cylinders, the bowl can be rotatably driven on threads on the base member for installing it and removing it. An upright extension is attachable to the slide bar and carries an auxiliary driver thereon disposed above the main driver so as to engage the projections on the bowl when such projections are above the plane of the main driver such as when installing or removing the bowl.

Abstract: A gyrating cone-shaped head cooperates with a stationary bowl support to crush rock or the like admitted into the crusher. The gyrating action of the head is accomplished by an off-set shaft arrangement for the head driven by a rotatable eccentric member. Input drive for the crusher rotatably operates the eccentric member through an independent coupler for improved gear alignment, operation and maintenance. The head has gyrating support on a dished bearing surface of the main frame, and hydrostatic pressure is admitted between the head and the frame support to minimize wear. Also, a fluid lift is provided for portions of the drive apparatus to support such parts and eliminate thrust loading caused by the weight of such parts on a radial roller bearing, thereby prolonging the useful life of the bearing. An improved seal is provided between the head and the main frame and is of a structure to remain intact and to operate effectively under all normal operating conditions of the crusher.

Abstract: A vibrating screen apparatus of the type wherein bearing housing discs and associated gears are mounted on self-aligning bearings which are supported by fixed internal spindles, with the gears centered on the bearings, and hubs connect the bearing housing discs to shafts extending through the spindles.

In one embodiment, a cam crank turns a bearing housing disc relative to an outer gear mounted thereon and a second cam crank limits such turning. In a second embodiment, a pinion is maually turned to turn a driving gear relative to a bearing housing disc.

Abstract: A flared distributor cap of a rotated impeller assembly directs material to be crushed radially outwardly to scoop-like impeller shoes which fling the material outwardly against breaker bars. The impeller shoes hook over mounting blocks and a pin and a screw will retain a shoe in place should the hook break. An annular distributor table carrying the mounting blocks and shoes has an annular, undercut groove in which interchangeable arcuate segmental wear plates fit. An undercut peripheral edge of a distributor cap overlies beveled, inner peripheral edges of the wear plates to lock them in position. Upper wear plates are secured to an annular distributor table cover, and have undercut grooves into which the cover fits.

Abstract: An impeller assembly having a hard wear plate has replaceable impeller shoes and is rotated on a vertical axis to throw material against vertically reciprocated, replaceable breaker bars to crush the material. The breaker bars are reciprocated by power driven jacks. The material is supplied to the impeller through a spout having a dust-sealing valve. The impeller has a shaft journalled in a sealed impeller shaft housing mounted resiliently on a base, and the shaft is driven by a double universal joint drive. Lubricant is pumped from a sealed input shaft housing into the impeller shaft housing and back to the input shaft housing.
