Abstract: In a balance device for a mechanical press, a press body or frame rotatably mounts a crankshaft. A slide is supported from the crankshaft by connecting rods so that it reciprocates transverse to the axial direction of the crankshaft as the shaft is rotated. To avoid the development of an oscillating effect in the press body during operation a first gear is positioned on the crankshaft. Balancing gears are supported on the press body in meshed engagement with the first gear. Each of the first gear and the balancing gears has a balance weight for counteracting the tendency of the slide to cause oscillation and vibrations in the press body.

Abstract: An anti-jamming mechanism for a device providing linear rotary movements consisting of a simple one-piece collar having split end portions with one of the portions anchoring the collar to a rotatable and axially movable sleeve driven by a screw mechanism, the other end portion acting as a spring-like flexible finger reacting against a stepped stationary housing portion to stop rotation of the sleeve while permitting its axial movement upon continued rotation of the screw until the finger clears the end of the step, whereupon the sleeve is permitted to rotate freely with the screw without further axial movement.
Abstract: A microtome actuable both manually and by a motor, with a single coupling element, whereby rotation of the hand wheel when the motor drive is engaged and thus the risk of injury by the manual grip are excluded. The coupling element is located in the hand wheel and is capable of locking in two positions by means of pulling and rotating, the respective positions establishing the manual or motor drive mode. The drive mode is made readily apparent from the outside by means of symbols. In the hand wheel, an equalizing weight for the object carriage is provided.
Abstract: An electric starter apparatus for small internal combustion engines wherein engagement of a starter pinion gear with engine flywheel gear teeth is produced by the axial translation of a nut member mating with helices formed on the motor shaft. An elastomer drive and cushion member is interposed between the nut and pinion gear wherein axial displacement of the pinion gear is through the elastomer, as is the transmission of torque to the gear. The elastomer includes an annular axially extending projection received within an annular recess defined in the pinion gear whereby the recess partially confines the elastomer during torque transmission and engine cranking, and concentrically locates the elastomer relative to the motor shaft.

Abstract: A tiltable steering apparatus for vehicles is provided wherein a movable bracket is rotatably supported in a holder member of a fixed bracket, a latch member having a toothed portion engageable with teeth of the holder member is provided on the movable bracket and means are provided for positively engaging and disengaging the toothed portion of the latch member and the teeth of the holder member.
Abstract: A motion generating system in which multiple movements are to be generated with multiple interrelated elements or multiple movement paths generated by a given input. There is a primary input which drives an acceleration-deceleration device from one stopped dwell position to another stopped dwell position. Associated with the drive device is a primary output member with multiple output means mechanically associated therewith and shift means in the mechanism driven by the input member to selectively connect and disconnect one or more of each multiple output means relative to the primary output means. The connection and disconnection is designed always to occur during a dwell position of the primary output means.
Abstract: A control assembly particularly for use in marine controls where a single lever thereof actuates a clutch and throttle of a marine power unit. The assembly has a first input shaft rotatable relative to a body thereof, and an extensible and retractable first output structure for controlling a function, e.g. the throttle. The assembly includes a cam mounted on the first input shaft for rotation therewith and a cam follower cooperating with the cam and the first output structure. A lever means cooperates with the body and cam follower so that the first output structure is actuated in an amount dependent on direction and rotation of the input shaft from an initial position thereof. In a preferred embodiment, a second output structure for the clutch is responsive to primary rotation of the input shaft from the initial position thereof and is unresponsive to secondary rotation, and the first output structure is unresponsive to primary rotation of the shaft and is responsive to secondary rotation thereof.

Abstract: A compact, safety, control assembly for lawnmowers having electrically started engines is provided which includes a "dead man" function and which requires two distinct steps for starting the lawnmower engine. The control assembly preferably includes a shiftable handle, a moveable lever, a cable connected to the lawnmower ignition assembly and shiftable between positions corresponding to the off, on and start position of the ignition assembly, a spring biasing the cable to the off position, a rotatable operating mechanism connected to the cable and engageable by the handle and lever, and a guide and slot assembly that enables shifting of the cable to the start position from the off position only after completion of a two-handed, two-step operation. In operation, the operating mechanism is rotated by the operation of the handle, thereby shifting the cable into the on position.

Typical field trays of the floor are coupled in pairs to a single air cylinder for economy of operation. The gear rack associated with the turning machine is independently adjustable to insure alignment of the gear rack. The floor includes stringer gage members to insure proper installation and alignment of the stringers. A wall panel is provided for updated restoration and automation of existing kiln floors.
Abstract: A pump jack comprises a rocker arm one end of which is fixed to the upper end of a sucker rod. The other limb of the rocker arm has rigidly affixed thereto a downwardly-extending drive support member and a large driven pinion is eccentrically and rotatably mounted at the lower end of this drive support member. The driven pinion is engaged by a chain, which also passes around a driving pinion fixed to the base of the pump jack. This drive arrangement reduces the acceleration and shock loadings imposed upon the sucker rod at the beginning of its upstroke and reduces the size and cost of the gearbox necessary to connect a prime mover to the driving pinion.
Abstract: This invention relates to a resettable force limiting assembly of the ball and screw type employed in a flight control actuation system. The resettable force limiting assembly includes a force transmitting reciprocating output member drivingly carried by an actuating member mounted for rotation in a housing. A reversible torque input is mechanically coupled to the actuating member to cause the output member to move in a direction dependent upon the direction of rotation of the input. A reciprocating reaction plate is secured for rotation with the actuating member. In operating cooperation with the reaction plate is a reaction plate engagement assembly that has elements secured against rotation to the housing. The elements are disposed on either side of the reaction plate. The elements have compression springs coupled thereto to resiliently separate the elements while allowing the elements to individually move towards and away from the reaction plate.
