Patent number: 5761968Abstract: A steering wheel "after-market" overlay, having a unitary, integral, relatively stiff, thin-walled construction, is adapted to be adhesively applied to and closely conform to the surface of the upper portion of an original equipment steering wheel. The overlay covers not only the upper portion of the steering wheel grip but also the upper portions of the steering wheel spokes up to the center pad of the steering wheel. The portion of the overlay covering each spoke has an radially inner terminus including a flange that is adapted to extend into the small space that typically exists between the inner end surface of the spoke and the side peripheral surface of the center pad. By also covering the upper portions of the spokes, not only is the appearance of the overlaid steering wheel enhanced, but the bonded surface area is substantially increased thereby assuring the long term positional stability and peel resistance of the overlay.Type: GrantFiled: July 29, 1997Date of Patent: June 9, 1998Assignee: Grant ProductsInventor: Tom A. Poteet

Patent number: 5761969Abstract: A torsional vibration damper has an annular driven member and an annular inertia member, coaxial with the driven member. The inertia member is capable of limited rotational movement relative to the driven member. At least one set of variable volume chambers is arranged so that the relative movement of the driven and inertia members in a first direction decreases the volume of one of the chambers and increases the volume of the other chamber, and relative movement in the opposite direction causes a reverse variation in the volume of the chambers. At least one annular spring is carried by one of the driven and inertia members. A connection is provided between the variable volume chambers and at least one side of the spring. The damper is supplied with a source of fluid in the chambers whereby relative rotational movement of the drive and inertia members pressurizes the one side of the spring causing it to flex.Type: GrantFiled: January 21, 1997Date of Patent: June 9, 1998Assignee: Simpson Industries, Inc.Inventor: Eric Malcolm Vollett

Patent number: 5761971Abstract: A mechanical press having a very precise shutheight control system is disclosed. The press includes a bed connected to a frame with a slide connected with the frame for reciprocating motion opposing the bed. The slide and bed together define a shutheight of the press. A drive mechanism is attached to the frame for driving the reciprocating slide, the drive mechanism includes a drive piston and a tie rod. The shutheight control system includes a chamber located between the drive piston and tie rod with a pressurizing mechanism in communication with the chamber for selectively pressurizing the chamber with a predetermined pressure. The pressurizing mechanism causes the tie rod to one of expand and contract to thereby control press shutheight.Type: GrantFiled: April 23, 1997Date of Patent: June 9, 1998Assignee: The Minster Machine CompanyInventors: W. Craig Brewer, Edward Daniel

Patent number: 5761972Abstract: A ratchet wrench having a handle and a head of know configuration with the head including a raceway in which is mounted a spur gear. The spur gear has a shaft passing through it which cooperates with the head of the wrench to hold the gear in place with one end of the shaft including a post for attachment of a socket. Within the head of the wrench is a pawl mechanism for engaging the teeth of the spur gear so that when the handle is rotated in one direction, the pawl mechanism will engage the spur gear and turn the spur gear, its shaft and the post to which a socket is attached. When the handle is rotated in the opposite direction, the pawl mechanism will ride over the spur gear so that the spur gear will remain stationary. The improvement of applicant's invention is an advancing lever built into the handle of the wrench. The advancing lever includes an advancing rod with camming teeth on the free end of the advancing rod and pivotally connected to a link rod at the opposite end.Type: GrantFiled: October 29, 1996Date of Patent: June 9, 1998Inventor: John A. Sanders

Patent number: 5761973Abstract: A double-headed wrench assembly includes an upper pressing member with a first driving head and a lower pressing member with a second driving head mounted on upperside and underside of a wrench body respectively. An upper thrust rod has an upper portion slidably mounted in the first driving head and a lower portion with a first enlarged head. A lower thrust rod has a lower portion slidably mounted in the second driving head and an upper portion with a second enlarged head abutting on the first enlarged head. A first biasing member is urged between a lower portion of the upper pressing member and the first enlarged head and a second biasing member is urged between an upper portion of the lower pressing member and the second enlarged head. A first ball is slidably retained in a first detent recess defined in the first driving head and is detachably received in a first cavity defined the upper thrust rod.Type: GrantFiled: October 22, 1996Date of Patent: June 9, 1998Inventor: Yi-ming Tung
