Patent number: 5893289Abstract: A machine (144) for crimping terminals onto conductors, is disclosed which automatically compensate for different conductor density and terminal sizes for maintaining a desired crimp height for each different combination of sizes. The machine (144) includes a compensating unit (146) that is interposed within the drive mechanism to automatically alter an otherwise fixed distance (162) in the drive mechanism. The compensating unit (146), when combined with the ram, includes a pair of opposed resilient beams (158, 160) that deflect when sufficient axial loading is applied to the ram during the crimping operation. This deflection results in the altering of the fixed distance (162) and, therefore, the altering of the shut height (164) of the machine (144).Type: GrantFiled: June 27, 1997Date of Patent: April 13, 1999Assignee: The Whitaker CorporationInventors: Michael Anthony Yeomans, David Joseph Erb

Patent number: 5839316Abstract: A hand-held crimping tool is disclosed having an air cylinder which retains thereto a head member, and has a moveable piston which is attached to a cam member. The cam member is receivable through the head member, and a crimping tool is fixed to the head member, whereby the cam member is cooperable with the crimping tool to move die surfaces towards one another for the crimping actuation of a wire terminal. The head member includes a pawl assembly, whereby the pawl member is cooperable with a ratchet surface provided on the cam member, whereby the cooperation of the ratchet and pawl determines the axial movement of the cam member relative to the head member, which also determines the crimping force exerted on the terminals to be crimped.Type: GrantFiled: May 28, 1997Date of Patent: November 24, 1998Assignee: The Whitaker CorporationInventors: Christopher James Kolivoski, Richard Lloyd Schaeffer, Jr., Michael Morris

Patent number: 5775229Abstract: Invention relates to an on-board electrical generator system that may be retrofitted to existing railroad vehicles, such as freight cars, box cars, and the like, where rotation of the vehicle's axle powers the system. A preferred use thereof is to charge the battery for the electrically controlled brakes on the vehicle. Such vehicles typically include a chassis, having plural axles mounted thereon, and a journal box or adaptor block having a projection generally aligned parallel with the axles. Each axle contains a pair of wheels, which are inwardly mounted from the respective axle ends and rotatable with the axle. The generator includes a rotor fixed for rotative movement relative to a stationary stator, whereby such relative movement causes electric currents to be generated in the stator containing the generator in a non-rotatable housing.Type: GrantFiled: October 20, 1997Date of Patent: July 7, 1998Assignee: The Whitaker CorporationInventors: Kenneth Foster Folk, Frank Mario Mastrog

Patent number: 5281091Abstract: An electrical an (10) for the icing-susceptible stator vane stage (16) located in an air inlet section (12) of a turbomachine (not shown). A plurality of stator vanes (20) which are electrically isolated from a plurality of structural shrouds (30, 32) are grouped in one continuous, or a plurality of contiguous arcs about a fanshaft which is generally coincidental with the turbomachine's longitudinal axis (X--X). Low voltage alternating current is provided by an alternator (not shown). This current is directed through a plurality of electrical conductors (26) and is further distributed through each stator vane (20) which is either electrically conductive or employs an electrically conductive medium disposed proximate to an icing susceptible surface of an airfoil contour (21). The electrical current flow, which is generally directed in a radial orientation through each stator vane (20) causes a direct electrically-resistive heating effect to the airfoil contour surfaces (21) of the stator vanes (20).Type: GrantFiled: December 24, 1990Date of Patent: January 25, 1994Assignee: Pratt & Whitney Canada Inc.Inventors: Kevin A.

Patent number: 5017092Abstract: A rotor blade (1) is disclosed which recenters itself in relation to the rotatable hub in which it is installed. Imposition of an external force (A) upon the rotor blade (1) creates a moment (M) which acts about the rotor blade's root (2). Recentering is accomplished by centrifugal forces acting through an offset distance (C) resulting from rotation of the blade root (2) about a shaped retaining pin (6), achieving an enhanced opposing restorative moment (M') on the rotor blade (1). The rotor blade (1) contains an arcuate bearing suface (8) within a chordwisely disposed slot (7) in the rotor blade's root (2). This arcuate surface (8) bears against a mating arcuate surface (9) with a smaller radius of curvature lengthwise disposed on the shaped retaining pin (6).Type: GrantFiled: October 16, 1989Date of Patent: May 21, 1991Assignee: United Technologies CorporationInventors: John A. Violette, Thomas Mashey
