Abstract: 1,031,589. Welding by fusions. AIR REDUCTION CO. Inc. Dec. 16, 1964 [Dec. 26, 1963 (2)], No. 51179/64. Heading B3R. Apparatus for reciprocating a tool, e.g. a welding electrode, has means for adjusting the location of the point about which the reciprocation is centred. In apparatus for arc welding a vertical seam between plates 62, the weld is retained by shoes 22, 24, respectively pivotally connected to an arm 66 of a frame 20 and an air cylinder 70 mounted on the frame 20. A slide 46 carrying the electrode 56 and adjustable cam followers 58, 60 has three bearings 48, 50, 52 sliding on rods 26, 28 fixed in the frame 20. A second slide 31 carrying a variable throw cam 42 and its driving motor has three bearings 32, 34, 36 sliding on the rods 26, 28. Adjustment of the cam 42 varies the amplitude of reciprocation and adjustment of the followers 58, 60 can provide a dwell at the ends of the movements of the electrode 56. The centre of reciprocation is varied by a dial 72 geared to a screwed rod 30 controlling the location of the slide 31. The dial 72 is disconnectable from the screwed rod 30 by a push-rod 87 and provides a reading equivalent to twice the adjusted distance of the slide 31. Thus if the dial is set to zero with electrode at the mid-point of its reciprocation located in the plane of the work surface engaged by the shoe 22, by setting the dial to indicate the thickness of the work, the electrode reciprocation is centred relative to the work. In a modification, a single spring-loaded cam-follower engages the cam 42 and the cam is shaped to provide dwell if required.

Title: Improvements relating to Spinning
Inventor: MACKIE JOHN KAY PRINGLE
IPC: D01H9/14
Filed: 1965-12-10
Abstract: 1,160,972. Builder motion. JAMES MACKIE & SONS Ltd. 7 Dec., 1966 [10 Dec., 1965], No. 52582/65. Heading D1D. A ring frame for balloonless spinning (i.e. the yarn is wrapped about the top of its spindle) of the type which operates at reduced speed while lowering the ring rails in readiness for doffing, is provided with mechanism such that the ring rail is lowered at a speed which ensures that the rate of increase in yarn path length from delivery rollers to bobbin is greater than the delivery speed of the yarn: thus ballooning and snagging of the yarn is prevented. The ratio of lowering speed of the rail to yarn delivery speed is preferably about 3:4. As shown, ring rail 4 is reciprocated by a drive originating at cam 11, see also Fig. 4 not shown. In the drive path is a winch mechanism 17 whereby the nail is lifted by small amounts during the build to shape the packages. When the build is complete a switch 31 and a switch 83 are simultaneously closed by elements associated with the builder mechanism and as a result the normal machine drive is stopped and a lower speed drive motor started and engaged to the main drive shaft. During the subsequent downward stroke a valve is opened by an element associated with the builder cam so as to actuate pneumatically a clutch 39; consequently the delivery rollers 36 drive the winch mechanism in a direction opposite to the normal one and the rail 4 is lowered more quickly: the gear train through which the winch mechanism is driven has interchangeable gear wheels to permit the drive ratio to be altered. When the ring rail reaches its lowest point the machine drive and winch mechanism is returned to normal operation. Undercoils are wound on the lower end of the bobbins and the machine is then switched off ready for doffing. The tappets above the spindles are pneumatically pivoted away during the doffing operation.
