Abstract: A combination condiment grinder and dispenser mechanism (10) which can be held and operated by one hand and which includes a hand-activated lever (80) which when squeezed forces a grinding surface (88,90) in one direction against spring (92) pressure. When the hand-actuated lever (80) is released, the grinding surface (90) reverses. The grinding action thus is linear or arcuate. The upper portion of the dispenser has a salt or other condiment compartment (38) which can be sprinkled from the top thereof. Only one hand is necessary to dispense either pepper or salt or other condiment from the body of the device.

Abstract: A condiment mill for grinding pepper, rock salt and other condiments has a base member with a grinder receptacle formed therein in which a grinder head is rotatably mounted. Also, mounted on the base member is a casing member forming a compartment for storing the condiment to be ground. A shaft extends from the grinder head and through the top of the casing member, a manipulator device for rotating the shaft being attached to the end thereof.

Abstract: An ice breaking head for an ice producing machine is adjustable for producing harvested ice of selected sizes. The ice making machine has a cylinder, the inner surface of which produces commercial sheet ice. The ice is harvested by forcing the ice from out of the cylinder toward an ice breaking head. The position of ice breaking head is adjustable to vary the size of the ice harvested. The head has an ice breaking surface which contains fins for facilitating the breaking of the ice sheet. It is journalled on a mounting post which has keys or ribs of increasing heights which match corresponding keyway slots in the bore of the head so that the spacing of the head, and hence the size of the ice harvested, can be adjusted by changing the rotational position of the head on its mounting post.

Abstract: A method and means for adjusting a forage harvester shear bar relative to its rotating cylinder. The outer end of the shear bar, the central portion of the shear bar and the inner end of the shear bar can all be selectively adjusted while the cylinder is rotating, these adjustments being made from the outer or operator's side of the harvester and at a common location. All of the shear bar adjusting means are located at one convenient and safe area at the outer or operator's side of the machine and the operator can accurately adjust the outer, central or inner end of the bar by noting the "tick" noise created when the particular end or portion of the shear bar being adjusted touches or comes in contact with the rotating knife of the cylinder.

Mechanical locking pins are hydraulically actuated by vertical hydraulic cylinders to mechanically lock the retracting plate in its forward position, and separate horizontal hydraulic retracting cylinders are provided to retract the retracting plate when the mechanical locking pins are disengaged therefrom, and to return the retracting plate to its forward position after the non-crushable material has been released from the crushing chamber of the crusher. The entire hydraulic system for the jam release is hydraulically operated through a series of suitable hydraulic valves preferably located at a central control station.

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: The shearbar of a forage chopper, positioned in such a way that direct access thereto for adjustment purposes is obstructed by other adjacent structures and mechanisms, is provided with an adjuster which may be manipulated at a point remote from the shearbar itself under conditions providing free, uninhibited access to the adjuster. A cam in the nature of a wedge is shifted infinitely along a path of travel that causes responsive shifting of the shearbar assembly along a path of travel extending toward and away from the chopper when a setscrew is released to permit such shifting on the part of the assembly.

Abstract: A forage harvester has a rotary cylinder type cutterhead mounted in a housing with opposite side walls, crop material being fed into the cutterhead in a generally radial direction over a shear bar adjacent the cutterhead periphery. The shear bar is mounted for fore and aft adjustment toward and away from the cutterhead periphery to maintain the optimum clearance between the cutterhead and the shear bar by means of a mechanism that includes a pair of bell cranks respectively pivotally mounted to support members on the opposite walls, with one end of each bell crank being connected to the shear bar through a fore and aft link while the other end of the bell crank threadably receives the threaded portions of a vertically elongated rod that is rotatably supported adjacent the housing side wall and has an easily accessible head adjacent the top of the housing, whereby rotation of the rod causes the bell crank to rock on its pivot to cause linear fore and aft adjustment of the shear bar.

Abstract: A support structure for a cutter bar for use in a forage harvester, the support structure adjustably supporting the opposite ends of the cutter bar and providing a convenient readily adjustable structure for supporting the central portion of the cutter bar to prevent movement of the central portion of the cutter bar relative to the cutting cylinder of the forage harvester and to afford adjustment of the position of the central portion of the cutter bar relative to the blades of the cutting cylinder.

Abstract: A rotary shredder for waste materials has a pair of counterrotating cutting shafts, each of which mounts a series of spaced-apart disc-type cutters. The cutters on one shaft extend into the spaces between cutters on the other shaft so that the cutters on the two shafts coact to shred material fed therebetween. The two shafts are driven by a reversible radial piston hydraulic motor through a gear train arranged to rotate one cutter shaft at twice the speed of the other. The hydraulic motor is driven by an electric motor-driven fixed or variable displacement pump. A flow-reversing valve in the hydraulic motor control circuit controls the direction of fluid flow through the hydraulic motor. The reversing valve is electrically actuated automatically by a fluid pressure-operated switch to reverse flow and the direction of rotation of the cutters to prevent jamming whenever fluid pressure in the motor circuit rises to an abnormally high level.
