Patent number: 8282452Abstract: An air handler (or air handler section) includes an enclosure containing various internal HVAC components and a bi-directional alignment system that during factor assembly of the enclosure helps align the enclosure's entire roof to the internal components. To help align the roof in a widthwise direction, a tapered lead-in edge in the upper corners of a block-off panel for an evaporator, filter rack, damper, fan and/or other HVAC component engages a roof rail that runs along the length of the roof. The upper corners of the block-offs also include a landing edge that engages the underside of the roof rail to help support the weight of the roof. Cross rails attached to the underside of the roof and extending along the width of the enclosure include an inclined lead-in flange that engages the upper edge of the various internal HVAC components, thereby helping align the roof in a lengthwise direction.Type: GrantFiled: November 6, 2008Date of Patent: October 9, 2012Assignee: Trane International Inc.Inventors: James M. Grigsby, Jeffrey C. Marks

Patent number: 6959972Abstract: A hinge assembly allows an access panel to be pivotally coupled to a cabinet, even though the cabinet includes a top cover that overlaps an upper edge of the panel. To open the access panel, a latch is actuated to first release a lower edge of the panel. The hinge assembly then allows the lower edge to be pulled out from over a base rail of the cabinet. Once the lower edge is off of the base rail, the hinge assembly allows the panel to be lowered without obstruction from the base rail. Lowering the panel then moves the panel's upper edge out from underneath the overlapping top cover. From there, the hinge assembly allows the panel to be swung open. To close the access panel, the process is reversed.Type: GrantFiled: November 15, 2002Date of Patent: November 1, 2005Assignee: American Standard International Inc.Inventors: James Russell Cude, Peter E. Simpson, Jeffrey C. Marks

Patent number: 6945041Abstract: A bent axis hydrostatic module, comprising: a frame, a pair of parallel laterally spaced shafts rotatably supported by the frame and directed outwardly from the frame in the same direction. Two yokes are pivotally mounted about parallel axes on the frame. A hydrostatic power unit is swingably carried by each yoke, and each hydrostatic power unit being operatively connected to one of the shafts to rotate the same. A pair of system pressure conduits in the frame with each of the pressure conduits are fluidly connected to each of the cylinder blocks. A control system is provided for pivoting the yokes including means for independently pivoting the yokes about parallel axes.Type: GrantFiled: December 18, 2003Date of Patent: September 20, 2005Assignees: Sauer-Danfoss, Inc., Deere & CompanyInventors: John Fleming, Scott Meyer, Doug Kardell, Christopher P. Masini, Jeffrey C. Marks

Publication number: 20040003915Abstract: A fin tube heat exchanger. The fin tube heat exchanger comprises: a first tube row including a plurality of tubes; and a second tube row including a second plurality of tubes. The first and second tube rows includes a slab portion respectively in contiguous parallel relation with the counterpart slab portion of the other tube row. Each of the first and second tube rows includes a respective first and second spread portion wherein the first and second spread portions are in diverging non-contacting relation with respect to each other.Type: ApplicationFiled: July 2, 2002Publication date: January 8, 2004Inventors: Glen F. Shippy, Jeffrey C. Marks, Allen E. Swaw

Patent number: 5111921Abstract: A park brake sensor valve is added to a circuit having an engagement override valve (EOV). The EOV normally prevents engagement of the transmission any time a vehicle is started with the speed selector in any position other than neutral. The park brake selector valve causes the EOV to disengage the transmission anytime the park brake is activated.Type: GrantFiled: November 20, 1990Date of Patent: May 12, 1992Assignee: Deere & CompanyInventors: Jeffrey C. Marks, Jon R. Delaney

Patent number: 4696205Abstract: A three-speed planetary transmission having a single ring gear and dual planetary gear sets meshing with the single ring gear. Gear changes are effected by coupling or alternately fixing a set of two sun gears which mesh with the two planetary gear sets. This transmission can provide a direct drive and two other speed ratios. Utilizing a single ring gear in combination with two planetary gear sets allows nesting of gear elements and economy of space for the transmission.Type: GrantFiled: February 4, 1986Date of Patent: September 29, 1987Assignee: Deere & CompanyInventor: Jeffrey C.
