Patent number: 5398790Abstract: An internal shoe drum brake has a pair of brake shoes mounted on a backplate with one pair of adjacent shoe ends in sliding engagement with an abutment fixed to or integral with the backplate. An actuator disposed between the other pair of adjacent shoe ends is operable to move the shoes, in use, into braking engagement with the braking surface of the rotary brake drum. At least the actuator or abutment is provided with shoe tip engagement surfaces of arcuate form and the respective engaging shoe tips have a generally complementary arcuate form resulting in a generally even wear pattern for the shoes.Type: GrantFiled: October 18, 1993Date of Patent: March 21, 1995Assignee: Lucas IndustriesInventor: Joseph H.

Patent number: 5264789Abstract: A method of determining the direction of rotation of a member (17) is closed, wherein the member has a speed pick-up rotor (27) having a plurality of teeth or exciter surfaces (29). The rotor has a predetermined pattern of gaps (37,73) and groups of teeth, each group of teeth having a number of teeth which is different than the number in any other group. As the rotor rotates, the pattern of gaps and teeth is sensed, and compared to a predetermined pattern. Depending upon the results of the comparison, the logic generates either a signal (61) representing clockwise rotation, or a signal (65) representing counter-clockwise rotation.Type: GrantFiled: July 27, 1992Date of Patent: November 23, 1993Assignee: Eaton CorporationInventors: Eugene R. Braun, Joseph H. McNinch, Jr.

Patent number: 4478777Abstract: A molding process for molding an elongated elastomeric member (60) with wire mesh sleeves (16) bonded to the ends (14). A molding preform (10) of elastomeric material is positioned within a seamless mold cylinder (26), and the open ends of the wire mesh sleeves (16) are mounted to end plug assemblies (30) slidably received into the mold cylinder (26) and positioned against the ends (14) of the preform (10). A specialized profile is formed into surfaces (44) of the respective end plug assemblies (30) and by heating of the mold (26), the ends (14) of the elastomeric preform (10) are molded to the profile, as well as bonded to the reinforcing wire mesh sleeves (16). Vacuum is applied to the interior of the mold to draw outgassing vapors through relief spaces therethrough. The completed elastomeric member (60) is removed from the mold cylinder (26) by stretching, the consequent reduction in diameter enabling ready separation from the mold cylinder (26) and removal thereof.Type: GrantFiled: February 25, 1983Date of Patent: October 23, 1984Assignee: Eaton CorporationInventors: Lyle O.

Patent number: 4171495Abstract: A wheel speed sensor including an annular rotor fixed to a wheel for rotation therewith and having circumferentially distributed surface interruptions. A sensing device mounted near the rotor is fixed against rotation and includes a sensing portion opposable across an air gap to the surface interruptions of the rotor to produce a signal representing rotation of the surface interruptions past the sensing portion. The rotor and sensing portion are of complementary generally V-shaped cross section and are separated by a V-shaped air gap such that the output signal is substantially insensitive to relative motion between the rotor and sensing device in an axial plane of the rotor.Type: GrantFiled: March 20, 1978Date of Patent: October 16, 1979Assignee: Eaton CorporationInventor: Joseph H.

Patent number: 4168866Abstract: A wheel lock control system for use with a vehicle having at least first and second spaced apart, independently rotatable wheels and having a braking system for applying braking forces to such wheels. A brake control responds to an applied lock signal for controlling the braking system to relieve the braking forces on the wheels. Input circuitry including nonlinear frequency to voltage convertors provides first and second wheel speed signals of values nonlinearly representative of the wheel speeds of the first and second wheels, respectively, such that for a given change in wheel speed there is a greater change in wheel speed signal at low wheel speeds than at high wheel speeds. Logic circuitry includes linear comparator circuitry responsive to the nonlinear first and second wheel speed signals for producing the aforementioned lock signal.Type: GrantFiled: September 9, 1977Date of Patent: September 25, 1979Assignee: Eaton CorporationInventors: Joseph H. McNinch, Jr., Daniel G. Smedley, David T. Klein

Patent number: 3995912Abstract: A skid control system is provided for use with a vehicle having a pair of spaced apart wheels and having a braking system for applying braking forces to the wheels. A brake control circuit responds to a skid signal obtained from any one of a plurality of incipient detector circuits to act upon the braking system to release the braking forces. A delayed skid signal is provided whenever the difference in wheel speeds of the two wheels exceeds a given amount. A delayed skid signal is also provided if the average wheel speed of the two wheels decreases at a rate greater than a desired decreasing rate. If both wheels decelerate, a skid signal is provided upon sensing that the faster wheel is decelerating at a rate greater than a reference rate. As the wheels spin-up toward an ideal velocity for a braked vehicle, an acceleration detector serves to insure wheel roll up on low friction surfaces. If the wheels spin up at an acceleration greater than an acceleration level, the acceleration detector output is inhibited.Type: GrantFiled: November 26, 1974Date of Patent: December 7, 1976Assignee: Eaton CorporationInventors: Joseph H.
