Patent number: 4669512Abstract: The projectile brake has two brake shoes movable relative to one another. The brake shoe carriers engage with spring pressure on either side of a wedge which is movable transversely to the application and release directions of movement of the brake shoes. When the wedge moves, the two brake shoe carriers move in opposite directions to one another; the two shoes move over the same distance relative to one another so that the longitudinal axis of the braking channel is always in alignment with the path of the projectile entering from the guide channel despite wear of the brake linings.Type: GrantFiled: December 27, 1985Date of Patent: June 2, 1987Assignee: Sulzer Brothers LimitedInventor: Otto Hintsch

Patent number: 4518019Abstract: The lubricator is disposed at the picking end of the picking element return device and has a guide duct for receiving a picking element prior to the next pick. The lubricator has oil mist nozzles which face only those surfaces of the picking element which will rub on the guide teeth in the next pick.Very low-quantity lubrication or lean lubrication is feasiable and soiling of the fabric by lubricant is obviated. The lubrication effect is sufficient to obviate metal abrasion between the picking element and the guide teeth so that soiling of the fabric by abraded metal can be avoided.Type: GrantFiled: August 16, 1983Date of Patent: May 21, 1985Assignee: Sulzer Brothers LimitedInventors: Otto Hintsch, Gerd Schmitz

Patent number: 4497346Abstract: The clutch arrangement contains a stroke member which carries two levers and a spring connecting the levers. The stroke member is driven by a drive lever which engages between the two levers. The stroke member drives the bar for the control levers while a scanning arm is moved against the armature of an electromagnet. Both movements occur with a force transmission occuring via the single spring. This provides for especially gentle treatment of the parts. At the same time, relatively few parts are needed.Type: GrantFiled: September 9, 1981Date of Patent: February 5, 1985Assignee: Sulzer Brothers LimitedInventors: Otto Hintsch, Werner Julich
-
Patent number: 4445546Abstract: The nozzles which are distributed over the width of the weaving machine remain activated after the passage of a weft yarn and are deactivated simultaneously upon termination of picking. Picking can be performed with fluid at a relatively low pressure so that the compressor for delivering the fluid can be relatively small.Type: GrantFiled: December 15, 1981Date of Patent: May 1, 1984Assignee: Sulzer Brothers LimitedInventor: Otto Hintsch
-
Patent number: 4427035Abstract: The clutch contains a spring for pulling the arm of the control lever on the stop and an additional auxiliary spring connected with a roller. While the control lever strikes on the stop, the roller moves toward one lever arm so that in a further rotation of the parts, the roller (30) is lifted within a slot while additionally tensioning the auxiliary spring. While the tension of the main spring decreases, that of the auxiliary spring increases correspondingly, so that the control lever is held with sufficient tension on the stop and machine vibrations during the striking or operation can be made harmless or damped.Type: GrantFiled: September 15, 1981Date of Patent: January 24, 1984Assignee: Sulzer Brothers LimitedInventors: Otto Hintsch, Werner Julich
-
Patent number: 4422482Abstract: The guide tooth of the weaving machine has an upper leg with a straight outside edge for passage through the spot threads in the low shed position in parallel relation. The length of the straight edge is greater than the interval between pairs of successive tangling points in the spot threads to insure entry between the threads without damaging the threads.Type: GrantFiled: November 18, 1981Date of Patent: December 27, 1983Assignee: Sulzer Brothers LimitedInventor: Otto Hintsch
-
Patent number: 4361017Abstract: The pattern mechanism uses final control elements which are controlled in accordance with a pattern for producing a controlled shogging motion of the guide bars or strips. Additional program-controlled control elements are added to avoid a loss in the shogging stroke. These latter elements are optionally controlled via a program carrier and prevent the pattern yarns controlled by the guide bars from being positioned into a faulty sinker lane irrespective of the length of the shogging stroke. The stroke of one correcting element can be, for example one quarter of the unit stroke of the main control elements while the stroke of the other added element can be one half of the stroke unit.Type: GrantFiled: June 6, 1980Date of Patent: November 30, 1982Assignee: Karl Mayer Textil-Maschinen-FabrikInventor: Otto Hintsch
-
Patent number: 4358940Abstract: The pattern mechanism for the warp knitting machine employs a reduction gear to change the shogging of the guide bar without changing the additive gearing. Elongated tension elements are disposed about the reduction gearing and have different parts secured to the reduction gear. The reduction gearing may be in the form of a multi-stepped roller or a roller having a periphery formed of curved portions of different radii.Type: GrantFiled: June 3, 1980Date of Patent: November 16, 1982Assignee: Sulzer Brothers LimitedInventors: Hans Gubler, Otto Hintsch

Patent number: 4333501Abstract: The weaving machine has a frame which includes a transversely extending main girder and a spaced apart and parallel supplementary girder at the warp end. The two girders are connected together by one or more connecting members so as to form a rigid connection between the girders. The supplementary girder is of U-shape cross-section and permits a mounted warp beam to project into the opening between the flanges of the girder. The connecting members each support a guide for the guiding of drive members for the shed-forming shafts of the weaving machine.Type: GrantFiled: March 17, 1980Date of Patent: June 8, 1982Assignee: Sulzer Brothers LimitedInventor: Otto Hintsch

Patent number: 4325520Abstract: The means for storing filamentary material comprises a U-shaped guide, a support which is slidable in the guide and a sensing element, e.g. a light source, which is carried on the support for the coil of yarn being stored. The support and the sensing element are very easily and accurately adjustable and retain the position to which they have been adjusted even during operation and are protected from vibration. Adjustment is facilitated by a fine adjustment means comprising teeth and a gear wheel meshing therein, so that the sensing element can first be moved manually (coarse adjustment) and thereafter be accurately moved into the required end position by means of the gear wheel and teeth (fine adjustment).Type: GrantFiled: October 6, 1980Date of Patent: April 20, 1982Assignee: Sulzer Brothers LimitedInventor: Otto Hintsch

Patent number: 4321951Abstract: The warp yarn stop motion is provided with a locating rail which is sub-divided into electrically insulated sections from the U-shaped rail. Each of these sections is electrically connected with pilot lights at the ends of each section. Should a drop wire fall on to a rail section, the pilot lights at the ends of the section are also illuminated so as to define the segment of the weaving width within which a broken warp yarn is located.Type: GrantFiled: March 24, 1980Date of Patent: March 30, 1982Assignee: Sulzer Brothers Ltd.Inventor: Otto Hintsch
-
Patent number: 4319469Abstract: The pattern mechanism has a carrier member extending in the longitudinal direction of the tension elements for the guide bars.
