Abstract: A mechanical force enhancement device which both amplified an input force to produce a larger output force while also reducing the speed of an output member during the latter part of the output stroke. The device employs a sequential pivoting operation which is capable of providing the above results while being uncomplicated in its design and construction. The device includes a housing having a pair of spaced-apart camming plates. Each camming plate has a pair of opposing camming contours formed therein so as to define two sets of spaced-apart camming contours. At one end of each camming contour is a recess so as to define two sets of spaced-apart recesses. A linkage member is disposed between the camming plates and includes a driven end adjacent one of the sets of spaced-apart camming contours and a driving end adjacent the other set of spaced-apart camming contours.

Abstract: A starter drive for an internal combustion engine having a clutch to provide rotary torque from a starter motor to a pinion gear connectable to a gear associated with an engine. The clutch has means for indexing the pinion gear to engage the gear associated with the engine, means for maintaining the teeth of the clutch engaged during the indexing function, means for automatically separating the clutch teeth when the engine starts and for maintaining separation of the teeth as long as the rotational speed of the pinion gear is greater than a predetermined speed. The starter drive includes two serially arranged resilient members between a driven clutch member and the sleeve on which the starter drive is slidably mounted. The housing is resiliently suspended between the two resilient members.
Abstract: A device for locating a datum reference on a partially assembled structural object, such as an automobile body frame. The device has a base structure for rigid mounting to a floor member, a transfer platform is attached to the base structure so that the transfer platform has freedom of movement in a first horizontal direction, a support structure is attached to the transfer platform so that it has freedom of movement therewith in a horizontal direction perpendicular to the first horizontal direction, a vertical slide support mechanism attached to the support structure and moveable therewith in a vertical direction, fluid actuated stop members for locking the horizontal and vertical movements of the device when a certain location in space, as dictated by the automobile body, has been attained. A work performing tool attached to the vertical slide support mechanism so that the tool can move into and out of engagement with the automobile body.
Abstract: An improved fastener and method of attachment to sheet material providing attachment of a tubular fastener to sheet material by extruding, without severing, portions of the sheet material completely through openings on the base portion of the fastener. The extruded material is clinched on the top surface of the base portion by clinch members integrally formed with the base portion. The fastener is internally threaded, lightweight and preferably heat-treated prior to attachment to the sheet material to provide fastener strength equivalent to or greater than that of much heavier nuts. Two types of such fasteners may be attached by a method which opens up a hole in the sheet material of a larger diameter than the major diameter of the threads in the fasteners while simultaneously clinching the fastener in place. This eliminates the need to use thread-cutting bolts. The fasteners may be connected together to form a strip to be fed into an automated assembly unit from a dispenser.
Abstract: Electronic disabling circuits are provided to prevent the engine of a motor vehicle to be protected from starting in the event of an attempt at starting the vehicle while the disabling circuits are switched on by a switch. An inhibitor device serves to prevent the disabling circuits from stopping the engine in the event the switch is actuated in an untimely manner while the engine is running. In addition, a detector for detecting the presence of a human being serves, via a circuit, to reliably trigger an alarm in the event of an intrusion, by applying a detection signal to an input of the circuit, assuming the circuits have been switched on by the switch.
Abstract: A motorized lifting device for loading and unloading articles from automobile trunks has a floor frame acting as a base for a pair of upstanding platform supports each of which has a flange. A carriage having a plurality of rollers is reciprocally mounted on each upstanding platform support such that at least two spaced apart rollers are on one side of the flange and at least one roller is on the other side of the flange. The flange, therefore, acts as a guide for the carriages when moving along the upstanding platform support. A platform frame is attached to the carriages and a platform rests on the platform frame. Lifting is achieved through means of a cable attached to each carriage, strung over a pulley on each upstanding platform support that is then wound onto a spool rod mounted to the upstanding platform supports. The spool rod is rotated by means of an electric motor powered by electricity from the automobile.
Abstract: A progressive hydraulic distributor with a slide for controlling a hydraulic actuator. The distributor has an internal load sensing passage that detects the operating pressure in the hydraulic fluid inlet or outlet passage and superimposes this pressure on the action of the spring of a feed valve. Thus, the difference between the up-flow and the down-flow of progressivity in the slide of the distributor is constant.
Abstract: A shock absorber element for protecting one or more fingers which are engaging a tool from experiencing a shock load when the tool experiences an impact load. The shock absorber element includes at least one shock absorbing pad and an interconnector for interconnecting the at least one shock absorbing pad with one or more fingers. The at least one shock absorber pad may be two blocks of resilient material, such as synthetic foam rubber, surrounded by a thin flexible casing formed, for example, of a woven fabric, thermoplastic film, a rubberized nylon material, leather, or vinyl. The interconnector may consist of two or more thin elongated strips, each having a first end fitted between the two blocks of resilient material and a second end extending therefrom through a suitable aperture in the thin flexible casing. Each of the second ends are interconnectable, for example, by use of hook and burr fastening elements.
Abstract: The invention concerns an anti-freezing device for pneumatic tools to avoid the immobilization of the striker piston because of freezing up. A thermally insulating sleeve, broken only at the level of the air exhaust apertures of the cylinder, separates the body of the hammer from an annular chamber into which the apertures open. An exhaust passage connects the annular chamber with the exterior and extends along the external wall of the exhaust silencer parallel to the striker piston. The exhaust silencer also is provided, above and below the annular chamber with two hermetically sealed chambers, which prevent the cooling of the naturally hot zones of the hammer by the air in the exhaust passage.
Abstract: A generally cylindrical tubular member is provided with securing means for detachably securing the member to a hand gun such that the member is positioned forwardly of the end of the gun barrel and so that the cylindrical body member is aligned with the bore of the hand gun. The cylindrical body member is formed with a clamping mechanism on the opposite end which, when clamped, causes the compression of a resilient spacer member and an annular resilient insert member which are disposed around the barrel of the hand gun. The compressing forces developed by the clamping mechanism causes the resilient members to frictionally engage the barrel without damaging the barrel.
Abstract: Fixturing for repair of automobile radiators is disclosed, usable for recoring of either brass or plastic tank radiators, including clamping gates providing parallel rails adjustably spaced to receive the radiator header with an air cylinder exerting clamping pressure on the tank top. The radiator sits atop the rails of a first set of clamping gates when resoldering conventional tanks and is recessed between the rails of a second set of clamping gates which are alternatively installed for decrimping and crimping of the header tabs of plastic tank radiators. Decrimping and crimping hand tools of special configuration are also disclosed, cooperating with the rails during use.
Abstract: A workpiece is urged against a chuck by a press plate supported by one end of a piston rod through a ball bearing. A rear end of a cylinder for the piston rod is swingably supported by a ball interposed between the rear surface of the cylinder and a stationary plate. Bolts for securing the cylinder to the stationary plate are formed with tapered portions mating with the tapered openings of bushings fitted to the supporting plate so as to selectively permit swinging motion of the cylinder.
Abstract: During the axial shirring of tubular casings into shirred strands while the material is inflated with air under overpressure, oil is intermittently injected without propellant air against the inside of the casing, so as to lubricate the inner wall of the casing. This eliminates the need for the costly construction required to provide for the discharge of excess air and oil needed with the known continuous oil injection through two-component nozzle with propellant air, and at the same time it insures a more uniform distribution of oil with reduced oil consumption. The injection nozzle is a single compound nozzle which is connected via electromagnetic valves to a conventional injection pump.
Abstract: The invention relates to a harvesting machine. A harvesting machine is disclosed in which a tunnel defining member is supported on a mobile structure such that when the mobile structure is moved through the vineyard, the tunnel defining member passes over a row of vine stocks. Mounted within each tunnel defining member are a plurality of thresher members, or beaters, which have extending vertically spaced flexible bush engaging rods. These rods selectively engage the vines in a directed motion to harvest the fruit from the fruit bearing stocks. Means, in the form of a transversely oscillating flexible lateral deflecting lining, are used to direct the harvested fruit in a predetermined direction. Selective placement of the thresher members results in separation of said harvested crop according to the aging of the crop.
Abstract: A direct cranking starter device for an internal combustion engine has a rotatable driving member to be connected to a starting motor and an overrunning clutch for engaging the driving member to the crankshaft of the engine with a movable shock absorbing member interposed between the driving member and overrunning clutch to prevent initial starting torque intermittent shock loads generated upon initial activation of the starting motor from being transmitted through the driving member to the overrunning clutch.
Abstract: A combination wrench is provided having an adjustable box-end wrench at one end and an adjustable open-end wrench at the other end. The box-end wrench includes a longitudinally movable adjusting member which forms a movable wall of a polygonal box structure integral with one end of a housing. The open-end wrench includes a pair of jaw members interconnected with the other end of the housing by a camming mechanism which effects lateral adjusting movement of the jaw members relative one another upon longitudinal movement relative the housing. The adjusting member and jaw members are coupled together for simultaneous movement to achieve same size adjustment at both ends. A one-way ratchet lock mechanism acts between the adjusting member and the housing and includes a plurality of ratchet teeth precisely located and spaced to size the wrences for each English size and metric size bolt to be fitted.
