Abstract: The rotary tilt exercise machine is a gravity-controlled device wherein the user, cradled in a body support unit, employs bodily balance and thrust to roll the body support unit, which is tiltably mounted on the ball joint of a housing drum. A pendular shaft is fixed to the base of the body support unit so that body support unit tilt produces angular displacement of the shaft within the housing. At its extension, the pendular shaft is weighted to provide ballast and centrifugal impetus to body support unit roll. Body support unit motion parameters are defined by either of two optional control devices, specified as a rotary wheel motion controller and as a crank arm motion controller. Auxiliary equipment includes a seat belt and grab bars mounted on the body support unit that stabilize the torso and enable body balance movements that work the back and abdominal muscles.

Abstract: A total body exercise machine in which an individual, seated in a body support sled, in a front or rear facing position, may use leveraged bodily force to elevate the sled against hydraulic and weighted resistance. A line trolley, suspended from a header by an assembly of pulleys and lines, tracks on a pair of rails, to pivotally support the upper end of the sled frame. At its lower end, the sled is pivotally joined to a frame mounted, radial indexing apparatus. That apparatus operatively positions a set of front and rear foot platforms, linked to the sled, to transmit leg force and assist in its elevation. Attached at the end of the lines is a set of hand rings, with which the user may use arm force, to help elevate the sled. Finally, the machine frame assembly is collapsible for shipping.

Abstract: A fitness sled exercise machine wherein a client user may, with the cooperative force of arms and legs, elevate a body carriage or sled, tracking on a rail attached to a frame base and foldable standard, from an at rest position to a point of elevation. The user may elect a front or rear facing exercise position to accomplish the elevation task. Body weight provides the primary resistance to elevation, supplemented by additional weights and/or the resistance of a stroke adjustable hydraulic cylinder.The specified frame standard is 90 degrees foldable for shipping, but may be locked in vertical position for operation. In the latter position, the standard supports a pulley and line lift apparatus that provides the user with an approximate 4:1 leverage advantage for upper limb manipulation of that apparatus. A system of levers and couplers serve to join the lift assembly to the sled and to foot bars located at the front and rear of the machine for lower limb participation in the elevation task.

Abstract: A traction sled exercise machine that provides two distinct exercise cycles, each of which employs bodily force to overcome gravity and elevate a body sled and user on an inclined frame supported rail from a point of origin to a point of destination. The structure and mechanics of this apparatus permits the user to confront machine resistance in a front or rear facing anatomical position. In either instance, arm force is extended through a block and tackle leveraging system, supplemented with leg pressure on one of two sets of adjustable foot stirrups provided for leg participation in the elevation task.The body sled has a companion mechanism, called the force beam assembly, designed to help regulate machine resistance. In that assembly, the body sled is in pivotal connection with a force bar that carries a position adjustable, weighted hanger.

Abstract: A Gravity Sled Exercise Machine wherein leveraged body forces act to overcome gravity to move a two piece body sled and client upward, along biangular support rails, from a horizontal to a vertical orientation. To support the torso during the change in spatial orientation, a fixed angle sled seat reciprocates in lineal motion on the lower of two differentially inclined rails. In concurrent action, the lower section of a back rest pivots on an axle at the rear of the seat, while its upper end rides via a pivot guide on the upper, more vertically inclined rail. That kinetic linkage produces a curvilinear motion that constantly repositions the sled and introduces variable resistance to the exercise cycle.An arrangement of handrings, lines and pulleys provides the leverage for arm and upper body exercises, while Class I and II levers enable leg and lower body exercises. A flexible coupling attaches a leg lever assembly to either the static lower rail or to the moving sled seat.

Abstract: A refrigerated mixing and dispensing machine for the preparation of frozen dairy products and ice mixed beverages. The machine has a housing within which is mounted standard industrial units such as a compressor, condenser, evaporative coils and regulatory equipment. Also mounted in the housing is a gear motor having a torque adjustable clutch designed to disengage the gear motor from the drive line in the event of an overload. Its unique configuration and integral receptor features function to conserve space and shorten the drive line. A mixing pump is connected to the clutch and it is of an offset, rotary cam design, that features a uniquely shaped and positioned plunger valve designed to transmit and regulate the pressure of fluids pumped from the mix tank to the dasher cylinder. Fitted to a cavity of the pump housing and extending above fluid levels of the mix tank is a sleeve type metering valve which functions to house the pump plunger and regulate the mixture of air and fluid entering the pump.

Abstract: The belt grinder provides a variety of vertical and horizontal position grinding options. The three wheel machine head features an offset axial mount, counterbalanced to rotatably elevate selected work stations. Total revolution of the machine head through 360 degrees produces six distinctive stations to accommodate diverse grinding requirements. The drive motor is mounted centrally within the machine head assembly and it has a drive shaft extending into the V-belt housing. One of the three wheels in the machine head is the drive wheel and it has a drive shaft also extending into the V-belt housing. Step pulleys are mounted on these respective drive shafts to give the belt grinder a speed change capacity. Tension on the abrasive belt and the V-belt is applied or released in incremental order with the revolution of a leveraged step cam. Articulation between two spring loaded idler wheels in the machine head insures synchronous tension, eliminates slack belt slap, and maintains consistent belt line geometry.

Abstract: A radial belt grinder having a drive wheel and a camber adjustable idler wheel coupled by a housing assembly. The housing assembly is rotatably supported on a machine radial groove by four shoulder bolts which also function to attach a C-framed motor to the base ring plate. A closed loop abrasive belt is transported about the wheels to accomplish multiple position platen and contour wheel grinding. An anti-recoil control mechanism facilitates belt exchanges and limits pressure recoil when the idler wheel is used in tilt angle, contour wheel grinding. A universal work rest arm, centrally supported at the rear of the housing assembly, provides the structure to adjustably support the work piece in infinite radial work positions through 180 degrees. A quick set friction lock functions to secure the rotatable housing at a selected radial angle. The work rest and all guards are reversable to accommodate left or right hand machine operations.

Abstract: A turret belt grinder having multiple contact wheels of different diameters mounted on tooling support members that are adjustably attached to a turret frame. The turret assembly is rotatably supported on flanged bushings bearing on a ring plate to revolve 360 degrees about, and concentric to, the axis of the motor drive shaft. A closed loop belt is transported in a fixed geometric pattern on the radial surface of the contact wheels. Each of the contact wheels may be rotated to a common work station to produce infinite belt angles and chages in wheel diameters. A friction rotor lock functions to fix the turret position to accommodate a variety of abrasive machining applications. The abrasive belt is driven by a V-belt which transmits power from the motor shaft to a contact drive wheel. Wheel mount member assemblies provide adjustment of the V-belt tension, abrasive belt tension and belt tracking camber. A leverage spring release mechanism permits rapid abrasive belt changes and maintains belt tautness.

Abstract: A single housing multi-sander assembly having a drive wheel mounted on a drive shaft, an idler wheel, a ring-shaped housing surrounding the radial drum surface of the drive wheel, an idler wheel mounting assembly, and structure for supporting the idler wheel mounting assembly a predetermined distance from the drive wheel. A closed loop abrasive belt passes around the radial drum surfaces of the respective drive wheel and idler wheel. The ring-shaped housing has a pair of radially spaced split through ways in the radial surface of the ring-shaped housing which function to form a path through which the closed loop abrasive belt passes. The ring-shaped housing has a support land located adjacent each of the split through ways to provide a support surface against which the underside of the closed loop abrasive belt may be pressed during sanding operations.

Abstract: A multi-chambered self-priming rotary pump having a pair of eccentric cams, each in contact with opposite sides of a rotor plate at one point and positioned 180.degree. out of phase so that the convex side of one cam is in direct opposition to a concave side of the other cam. At one point of contact on the convex curves, the cams bear against the side surfaces of the rotor which in turn forms a running seal with the bore of a housing to define two symmetrical enclosures at each side of the rotor. During rotation, a split core closure valve reciprocates between the surfaces of the cams and in so doing, the closure valve functions to produce an area of compression to the front of its travel with an area of vacuum to the rear of its travel. As one chamber phases out of cycle, its counterpart is producing maximum outputs.
