Patent number: 8851028Abstract: A cooling system for a fan drive device, particularly for a wet friction clutch. The clutch shaft member is attached to a shaft mounting plate and ATF is circulated through them. The shaft mounting plate is connected in turn to an engine mounting plate which has engine coolant circulated through it at a lower temperature. The shaft mounting plate and engine mounting plates both have passageways for circulation of fluids therein.Type: GrantFiled: March 2, 2009Date of Patent: October 7, 2014Assignee: Borg Warner Inc.Inventors: Dale M. Pickelman, Jr., Theodore A. Malott, Thomas M. Tembreull

Patent number: 8607745Abstract: A fan drive system is provided that is hydraulically controlled having an electrical failure mode wherein midrange operation of the fan drive system is maintained. Accordingly, in the failure mode, a fan drive system hydraulic relief valve is not closed thereby ensuring a degree of operation of the fan drive system even during periods of electrical failure.Type: GrantFiled: October 23, 2009Date of Patent: December 17, 2013Assignee: BorgWarner Inc.Inventors: Theodore A. Malott, Jr., Joshua L. Roby

Patent number: 8522945Abstract: A failsafe system for a heavy-duty multi-speed clutch includes a thermal valve coupled within a clutch pressure tube orifice circuit protecting a clutch pack from heat degradation. When oil temperature of the clutch reaches a level where thermal degradation can occur, the thermal valve allows flow into a clutch piston system at a maximum operating pressure, thereby engaging a clutch drive and cooling the clutch to a safe condition.Type: GrantFiled: December 22, 2007Date of Patent: September 3, 2013Assignee: BorgWarner Inc.Inventors: Dale M. Pickelman, Theodore A. Malott

Patent number: 7047911Abstract: A hydraulically controlled fan drive system for controlling the cooling of an engine and having a method of engagement includes a housing assembly containing a hydraulic fluid and an engaging circuit. The engaging circuit includes a pitot tube coupled within the housing assembly that receives at least a portion of the hydraulic fluid as the housing assembly rotates to drive a clutch pack (and coupled fan) via static pressure. A fluid controller having binary control adjusts the static pressure within the pitot tube at a given rotational speed, thereby controlling the engagement of the clutch pack to a fully engaged drive (utilizing friction type engagement), a fully disengaged drive, and at least two partially engaged clutch positions (i.e. partially engaged utilizing a wet viscous type clutch engagement). To control static pressure release, the fluid controller may utilize a dual spool system valving arrangement or a parallel fixed orifice binary control.Type: GrantFiled: August 27, 2003Date of Patent: May 23, 2006Assignee: BorgWarner Inc.Inventors: Neil E.

Publication number: 20050047567Abstract: A method for communicating information to a caller on a telephone network is herein proposed. The method includes the steps of (a) generating a signal suitable for producing an audible dial tone, (b) transmitting the signal to the receiver of a telephone set, when the caller initially takes the receiver off-hook, to thereby produce the audible dial tone, and (c) superimposing an audible information message over the audible dial tone while the audible dial tone is produced. The audible information message may, for example, be a branding-type message that identifies a provider of local telephone service to a caller. The audible information message may be superimposed over the audible dial tone in a whisper-like or low-decibel manner to avoid interfering with modems that operate on a “wait for dial tone” (WFDT) basis.Type: ApplicationFiled: August 27, 2003Publication date: March 3, 2005Applicant: BORGWARNER, INC.Inventors: Neil Robb, James Ignatovich, Dale Pickelman, Theodore Malott, Gary Hart

Publication number: 20040083609Abstract: A two-piece molded fan assembly is produced having overlapping fan blades using an axial draw technique. The two halves are then removed from the mold and coupled together to form the two-piece fan. By molding the fan as two pieces, a fan blade can be produced that wraps around the outside of the housing and overlaps with each other in a quick and easy manner using a simple mold design. The two pieces are formed such that the a portion of each overlapping blade is formed on both halves of the assembly so that the die casting tool can be removed along a central axis defining the fan assembly without contacting the respective portion of the fan blades, therein greatly simplifying the manufacturing techniques.Type: ApplicationFiled: November 4, 2002Publication date: May 6, 2004Inventor: Theodore A.

Patent number: 4432251Abstract: A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft. The cams are arranged on the shaft so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts. The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever.Type: GrantFiled: January 29, 1981Date of Patent: February 21, 1984Assignee: Clark Equipment CompanyInventor: Theodore A.
