Title: Improvements in or relating to yarn or like winding machines
IPC: B65H54/16
Filed: 1928-12-08
Abstract: 317,032. Universal Winding Co., (Assignees of Jones, C. H.). Aug. 9, 1928, [Convention date]. Addition to 312,626. Winding-machines; thread-guides; stop-motions.-The traverse mechanism described in the parent Specification and wherein the yarn-guide, which is traversed to deposit the yarn in successive conical chases, is rocked about an axis parallel to the winding spindle to cause it to follow the conical contour of the winding without contacting therewith through the medium of a rockable longitudinal track mounted parallel to the pivotal axis of the guide and engaged thereby, is modified so that the rocking movement of the track instead of being effected by a crank or like member is derived directly from the longitudinal traversing movement. The yarn-guide 58, Figs. 2 and 3, is pivoted about an axis 24 parallel to the winding spindle 3 and is positively rocked thereabout by the action of a follower 76, traversed longitudinally with the guide 58, engaging a camtrack 75 in a frame-member 65. The frame 65, Fig. 5, is pivoted at 70 on bushes 47 held in the bearings 26, 27 of the traverse frame 28 and is formed with a rail 67 and an arcuate portion 74 concentric with the traverse rod 24, the part 74 having a cam slot 75 in which slides the pin 76 projecting from a member 77, Fig. 7, secured to the traverse bar 24 by the screw 49 which serves to clamp the arm 23 thereto. The yarnguide holder is formed with a shoe 84 adapted to straddle the rail 67. As the pin 76 is traversed together with the bar 24 the frame 65 is caused to rock through the engagement of the pin 76 in the slot 75. This oscillation is transmitted to the guide 58 through the members 67, 84, the cam-slot 75 being proportioned to carry the guide over the desired range. To adapt the machine to wind bobbins of different sizes the framemember is provided with a cam-slot adjustable thereon, e.g., the slot 85, Fig. 6, adjustable on the frame 87 by -means of the screw-and-slot connection 89, 90. If desired the machine may be arranged so that the winding-spindle reciprocates instead of the thread-guide. When the winding is completed the machine is stopped as described in the parent Specification.

Abstract: 1,114,643. Thermal responsive devices. CONTROLS CO. OF AMERICA. Aug. 24, 1965 [Oct. 26, 1964], No. 36421 / 65. Heading G1D. [Also in Division F4] A control device comprises a conduit C 2  for a gaseous medium having a restriction R 1  at its inlet and R 2  at its outlet, means for heating the medium flowing through one of the restrictions, and means effected by a change in condition i. e. pressure of the medium in the conduit resulting from such heating. Conduit C 2  is joined to a housing 12 by a further conduit 10 so that the pressure in conduit C 2  is applied to the underside of a diaphragm 14 movement of which against spring 16 completes the circuit across contacts 20. The rise in pressure below diaphragm 14 is due to heating of restriction R 2  heating of restriction R 1  causes a drop in pressure in C 2  . The inlet pressure in C 1  should be kept constant and this is accomplished by the arrangement described with reference to Fig. 2, where two connected diaphragms 28, 30 are used. The pressure on diaphragm 30 when restriction R 2  is hot is sufficient to hold valve 32 open and when R 2  is cold pressure on 28 is sufficient to close valve 32. In this embodiment the restriction R 2  is a capillary tube turned back on itself so that the issuing fuel may be ignited to heat the restriction R 2  . Modifications may be made to ensure that the system is closed if the restriction R 2  becomes blocked on the pilot burner is extinguished. The invention is described applied to a complete control system for a gas burner.
