  • Patent number: 4544136
    Abstract: The invention relates to a new and improved tire lift/carrier featuring a reel assembly comprised of a rotatable spool formed of thin metal plates abutted one to the other in a side by side relation, a portion of which plates defines a cavity in which one end of a line is held captive, the other end of which line is adapted to extend to releasably connect to a load which places a tension on this line in use. In the preferred embodiment described the spool has a single track within which the single line in connection with the spool is constrained to wrap directly on itself. The connection of the line to the spool is such that the spool may be rotated in either of opposite directions and in either case the line will wrap smoothly on itself. In the preferred embodiment illustrated the spool has a press fit gear through the medium of which it is driven in either of its opposite directions of rotation.

  • Patent number: 4518310
    Abstract: Apparatus associated with a component part of the drive system of a turbine assembly reduces the power applied to its drive rotor in a direct and substantially instantaneous response to the speed of its rotation rising to a predetermined level. A turbine starter for an engine embodying this apparatus comprises a housing for its rotor and the drive system of which it forms a part, a flow path for a gaseous fluid, delivered from a source, to power the rotor and a control device in connection with the drive system a component part of which moves radially thereof and, when its speed of rotation rises to a predetermined level, triggers a substantially simultaneous restriction of the flow path through which fluid can be applied to power the turbine rotor, thereby to produce a resulting reduction of the speed of rotation of the turbine drive system. If under such conditions the starter is engaged with a related engine, it will automatically disengage.

  • Patent number: 4509896
    Abstract: A rotor is distinguished by parts including a radially innermost part and a radially outermost part which is actually a separate element. The two parts are normally coupled for their conjoint rotation by pins anchored to project radially from the innermost part and freely into apertures in the radially outermost part. The pins provide a bearing mount thereon of the outermost part which is fabricated to radially expand and contract in correspondence with the speed of rotation of the rotor and to have a benign failure in the location of one of the apertures upon excessive speed of the rotor. By virtue of such failure the radially outermost part opens and expands to be braked by engagement with the particular surface most adjacent its outer periphery. This rotor is particularly advantageous for use in providing a turbine drive unit, in which event its power transmitting outer peripheral portion is formed by turbine buckets.

  • Patent number: 4507047
    Abstract: As originally fabricated the rotor of the invention is a unitized structure an outer portion of which, including its outer peripheral surface, is designed to separate shortly after the start of its rotation. As illustrated, this outer peripheral portion is a ring-shaped structure which is initially incorporated by an interference fit which establishes it in a fixed bounding relation to the rotor part immediately inward thereof. At the point in time that said outer portion of the rotor is separated, guide means are rendered operative to maintain a drive coupling as between the outer and inward rotor parts and such guide means then serve as bearings accommodating the radial movement of the outer separated part in correspondence with its changing radius in response to changing speeds of rotation of the rotor. Any failure of the rotor is benign in that at such time the rotor exceeds the designed limit of its speed of rotation the outer part expands sufficient to brake against its adjacent shield or housing.

  • Patent number: 4494499
    Abstract: A system for obviating chance damage in starting a diesel engine due, for example, to hydraulic lock utilizes a two step starting cycle and includes means for applying power to initiate and maintain a drive of the engine for starting thereof and associated controls rendered operative on a drive of the engine to sense the speed of crankshaft rotation and interrupt said application of power in response to a pre-set speed thereof which is substantially less than that required to start the engine to induce thereby a reduction of said speed and in response to such reduction a reapplication of said power. A portion of said controls is conditioned to automatically respond to a predetermined extent of rotation of the engine crankshaft to nullify ability of the controls to thereafter functionally interfere with the engine drive, whereupon there is an increase in the speed of crankshaft rotation to a level sufficient to induce a starting of the engine and its normal operation.

  • Patent number: 4473239
    Abstract: Apparatus providing an improved stabilizer pad assembly or foot construction for outriggers or stabilizer arms provides a housing containing a stabilizer pad in a manner to provide for a three dimensional relative movement therebetween under shifting load conditions. The housing of such apparatus is shell-like in character and has openings in its side and bottom, the side opening accommodating a slip fit therein of a stabilizer pad and its containment without any positive interconnection thereof to the housing. The containment of the pad is achieved by the application of a readily releasable rod to and across the side opening to the interior of the housing. The opening in the bottom of the housing provides for the dependency therethrough of an anchoring element forming part of the pad, which may be reversible in character.

  • Patent number: 4443187
    Abstract: A heater including a generally cylindrical shell defining its housing arranged in a very closely spaced relation to the outer periphery of its combustion chamber assembly and its fan device as it bounds a plenum chamber therebetween. The combustion chamber assembly has its discharge end adjacent the discharge end of the shell. The relative configuration of the outer peripheral surface of the combustion chamber assembly and that of the discharge end portion of the shell creates therebetween a passage through which the fan device, on energization thereof, produces a very high velocity flow of a thin layer of air which, on discharge, is throttled and abruptly and sharply driven into the center of the flow from the assembly. The effect of this is to moderate and influence a relative uniformity of the temperature of the discharge and rapidly project it outwardly of and considerably beyond the heater.
