  • Patent number: 4382710
    Abstract: A joint assembly between structural members having plate portions includes an eliptical opening through the plate portion of a first member and a notched locking plate portion on a second member. The latter plate portion is introduced through the eliptical opening parallel to the major dimension thereof and is then rotated 90.degree. to a locking position parallel to the minor dimension of the opening, whereby the notches interengage with the first plate portion to restrain separation of the two structural members. Resilient spring clips are mounted on the first plate portion outwardly adjacent the eliptical opening in the direction of the minor dimension thereof to releaseably engage the second plate portion against rotation when the latter is moved to the locking position. In another embodiment, a composite beam is assembled from a plurality of structural members having plate portions provided with eliptical openings therethrough.

  • Patent number: 4377369
    Abstract: A crane is mounted on a platform having ground engaging legs adapted to support the platform in an elevated position straddling railroad tracks so that a railway car to be loaded or unloaded is adapted to be moved beneath the platform. The legs are adapted to be displaced between raised and lowered positions relative to the platform and are in the lowered positions thereof when the platform is so ground supported. When a railway car has been moved beneath the platform, the legs are displaced toward their raised positions whereby the platform is lowered onto the car to rest on the top edges of the side walls thereof. The platform carries clamping arrangements for releasably gripping the side walls of the car when the platform is supported thereon, and the crane is operable with the platform supported on the car to achieve the loading and/or unloading thereof.

  • Patent number: 4370878
    Abstract: An improved workpiece ejecting system for presses includes an ejector piston hydraulically driven in response to reciprocation of the press slide in a manner whereby the motion of displacement of the ejector piston corresponds to the motion of displacement of the press slide during the stroke thereof, and the extent of displacement and velocity of the ejector piston are proportional to the corresponding characteristics of the slide. Ejector piston displacement is achieved by the flow of hydraulic fluid to and from the ejector piston chamber during reciprocation of the press slide through its total stroke. Ejector pins of various lengths are selectively associated with the press tooling and ejector piston to provide for varying the length of the workpiece ejecting stroke.

  • Patent number: 4369875
    Abstract: Apparatus for isolating and feeding objects, particularly sweets, to a pang machine in which objects are transported on a conveyor in a longitudinal row closely one behind the other, displaced sideways one at a time and accelerated to a higher speed spaced longitudinally from one another. Sideways displacement is provided by pressure pieces moving longitudinally with the objects and providing abutment stops for the next succeeding object to be isolated. Part of the rear face of each object is exposed by the sideways motion and a dog of a dog-chain engages the object at this point at the same speed as the pressure piece and then accelerates the object engaged by it such that the row of objects is longitudinally spaced one from another.

  • Patent number: 4363330
    Abstract: There is provided a method, system and apparatus for cutting a profile, such as a cigar wrapper, from a natural leaf, such as a tobacco leaf, wherein the leaf is spread and supported on a support surface in a random position. Thereafter, a leaf facsimile or image, including the leaf outline and surface imperfections, is developed and at least one cut position for the wrapper is located in an area excluding the leaf outline and surface imperfections. This cut position is recorded and converted to digital data. The wrapper is then cut from the leaf at an actual cut position corresponding to the located cut position determined by the digital data. Also, the facsimile is created by a back lighting arrangement which illuminates color variations and surface imperfections, as well as the leaf outline, so that leaf color variations can be included in the facsimile or image.

  • Patent number: 4360862
    Abstract: A nautical light for watercraft includes a cylindrical metal housing having opposite ends, one of which includes a collar for mounting the light on a tubular mast or pole. The housing includes a pair of vertically tiered light chambers each having a lamp bulb coaxial with the housing axis and a window opening radially thereinto through the housing. A cylindrical closed end lens is axially received over the housing with the closed end of the lens overlying an end wall of the housing opposite the mounting end. The lens member is sealed with respect to the housing, and the closed end of the lens member is fastened to the end wall of the housing to facilitate removal of the lens for access to the light chambers. The housing and mounting collar provide a path for heat transfer to the mast on which the light is mounted, thereby providing thermal protection for the lens.

  • Patent number: 4358880
    Abstract: There is provided a quick release hardware snap of laminated construction formed from at least two stamped sheet material blanks, of mirror image, combined to provide a laminated, sheet material body of generally flat configuration having a fixed load supporting hook extending from the body with a free end and an open side with a latchable, locking finger coupled to the free end. The latchable finger is releaseably retainable at the body by a biased, locking sleeve reciprocally mounted about a tubular portion of the body. The locking sleeve is mounted so that a spring within the tubular portion of the body urges the locking sleeve toward the latchable finger for securing one end of the finger to the body, for closing the hook. The locking sleeve may be moved along the tubular portion of the body, against the biasing force to a position whereby the latchable locking finger is released for quick release of the load retained by the load supporting hook.

  • Patent number: 4356940
    Abstract: Apparatus for dispensing measured amounts of molten metal to a metal casting operation which is automatic in operation and capable of delivering extremely accurately controlled amounts of metal to the casting operation. A positive displacement pump delivers the molten metal from below the surface of the metal to a dispensing point and a pulse generator generates pulses in exact proportion to the displacement of the pump and delivers such pulses to counters, the counters being started in operation when the metal being pumped contacts a probe at the dispensing point, the counters stopping the pump when an exact amount of displacement of the pump has occurred. Rate multipliers are provided between the pulse generator and the counters to compensate for leakage in the pump, variations in volume delivered for a given displacement of the pump or other unanticipated variables.

  • Patent number: 4357045
    Abstract: A tubular air screen producing device is mountable on a draft vehicle adapted to tow a trailing vehicle therebehind and has an air inlet end in the direction of towing and an air outlet end for discharging a screen of air toward the horizontal and vertical edges of the front end of the trailing vehicle. The outlet end of the device is of smaller area than the inlet end and is configured to direct a screen of air toward the trailing vehicle edges at a velocity higher than the velocity of air relative to the draft vehicle moving at a given velocity relative to ground. The high velocity air screen streamlines the area between the draft and trailing vehicles and shrouds the space therebetween, so as to minimize air turbulence in the space and along the top and side walls of the trailing vehicle. Thus, air drag is reduced and fuel economy is increased in connection with the towing of a trailing vehicle.

  • Patent number: 4352220
    Abstract: Method for the construction of a cable-stayed or rein-girth bridge in which the stiffening beam is built together with the guying provided for the final state by the cycle-pushing method and brought into its final position. The guying takes over in this case the support of the stiffening beam during mounting and displacement of the bridge, so that temporary supports between the bridge piers and a temporary guying at the front end of the super-structure are not required.
