Patent number: 4805822Abstract: A tractor for driving web material has an endless belt which travels about spaced apart drive and idler sprockets, one of which is an entrance sprocket and the other an exit sprocket. The idler sprocket is journalled in a support member which is movable on the tractor chassis by an adjusting member to vary the spacing between the sprockets and thereby adjust the tension in the belt. The belt carries the paper over a rectilinear path between the sprockets and the chassis has upper surfaces along that path which rise prior to the exit sprocket to lift the paper on the drive pins on the belt and provide a ramp surface clearance to effect clearance of the drive pins in the perforations of the paper so that they rotate downwardly without excessive wear and friction between the web around the perforations and the surface of the pins.Type: GrantFiled: December 21, 1987Date of Patent: February 21, 1989Assignee: Data Motion, Inc.Inventor: Arthur J.

Patent number: 4803834Abstract: The jacket enclosing a motor driven textile spindle of the type wherein the spindle is driven by a separate motor which is mounted on a common base with the spindle is modified to include air inlet and air exit openings. The motor is located in proximity to the spindle and is coupled to it by a toothed belt or the like. As the spindle is rotated by the motor air is drawn in through the inlet opening of the spindle and exits through the exit openings in the form of a strong stream of air which blows on and cools the motor. In this manner the spindle doubles as a fan for the motor and the necessity of providing a separate fan for the motor is avoided, resulting in savings in space and energy for driving a fan.Type: GrantFiled: December 21, 1987Date of Patent: February 14, 1989Assignees: FAG Kugelfischer Georg Schafer (KGaA), N.V. Van der Eecken & Co.Inventors: Walter Vogel, Wolfgang Schmucker, Erwin Leurer, Francois Beel

Patent number: 4798009Abstract: The spring comprises layers of resilient material connected and spaced apart by compression members. The compression members are also spaced apart and indexed so that those between one pair of layers are located opposite the spaces between the compression members between the adjacent pair of layers. Springs of various shapes and areas are cut from sheets of spring structure and the spring rates are expressed in terms of pounds per inch per square inch of spring work area. Spring rates range from 1000 to 1250 pounds per inch per square inch of spring. Work capacities range from 13 to 120 inch pounds per square inch of spring. Ratios of work capacity to weight range from about 200 for springs about 1/4 inch thick to 600 for springs 3/4 inch thick. The cavities in the springs are vented to ambient to enhance linearity and efficiency.Type: GrantFiled: March 28, 1988Date of Patent: January 17, 1989Inventors: Richard C. Colonel, Devere Lindh

Patent number: 4796418Abstract: Two parallel-inserted thread ends are introduced into a thread end preparation device via an air gap located above a preparation tube. The thread ends are cut by shears and thereafter an air flow produced in an air intake tube blows the thread ends into the preparation tube. The prepared thread ends are brought by retracting levers into the vicinity of the splicing chamber. The splicing chamber is provided with a cover and splicing is carried out by supplying a compressed air flow.Two thread ends are spliced together after cutting by exposing the two ends to a single air flow to prepare the ends for splicing by untwisting the ends and removing loose thread parts therefrom. The cut and prepared ends are disposed in a splicing chamber and compressed air is passed through the chamber to splice the ends together.Type: GrantFiled: April 1, 1987Date of Patent: January 10, 1989Assignee: Maschinenfabrik Schweiter AGInventors: Arthur Rebsamen, Bruno Hablutzel
