Title: Improvements in multiple needle sewing machines
IPC: D05B57/12
Filed: 1920-03-19
Abstract: 153,226. Thompson, W. P., (Union Special Machine Co.). March 19, 1920. Multiple-needle machines; double-loop stitching.-In a machine having a threaded looper cooperating with each needle, a reciprocating spreading-finger associated with each looper engages the looped thread and holds it away from the looper to ensure passage of the corresponding needle between the looper thread and the looper. Four needles 4, Figs. 12 and 13, disposed in a plane at right-angles to the line of feed cooperate with four loopers 8 carried on a shaft 10, Fig. 3, which is rocked by a crank 12: on the main shaft 6 to cause the loopers to enter the needle loops in the line of feed. To give the loopers their needle-avoiding movement, the shaft 10 is also moved axially through connections from a sleeve 14 rocked about the vertical pivot 15 by an eccentric 18 on the shaft 6. The spreading fingers 38 are adjustably mounted in carriers 39 adjustable about and along a shaft 41 constrained against rocking movement, but moved axially to cause the hooked ends 50 of the fingers simultaneously to engage the looper threads l, this movement combined with the opposite needle-avoiding movements of the loopers opening out the looper threads for the next descent of the needles, Figs. 12 and 13. The shaft 41 is thus moved by the rocking sleeve 14 through connections comprising the link 46. To enable the fingers to be set close up against the work, the throat plate 35 is cut away at 51, and to allow the fingers to carry the looper threads freely laterally, the needle slots 37 in the throat plate are provided with recesses 52, as shown in Fig. 13.

Title: Improvements in or relating to the ionising of gases, more particularly applicable to conditioning air for ventilation
IPC: A61L9/22
Filed: 1933-03-20
Abstract: <PICT:0420360/III/1> <PICT:0420360/III/2> <PICT:0420360/III/3> Mixtures of positive and negative small ions in desired proportions are obtained by supplying to two sharp electrodes positive and negative high potential current respectively and varying the length of the path from one or other of the electrodes to earth whereby with increasing distance between one electrode and earth a greater proportion of ions of the same sign as that electrode is produced. The high potential is preferably derived from a rectifying valve 11, Fig. 1 (Comp.), supplied from a step-up transformer 1 and is of the order of 10,000 to 50,000 volts.  A condenser 16 may be connected as shown to minimize fluctuations of potential.  An earthed plate 23 is interposed between the electrodes 20 and 22 and its position may be varied. Alternatively, the electrodes may be surrounded by cylindrical grids of variable diameter.  Fig. 2 (Comp.) shows the application to a portable apparatus, the ionizing device being contained in a casing 51 with gauze or like ends 69, and a fan 67 being arranged to circulate a current of air through the apparatus. The electrodes are constituted by rods 58 and 61 having sharp projections 58<a> and 61<a>.  The earthed conductor consists of a rod 62 pivoted at point 63 and adjustable by means of handle 64.  Fig. 2 (Prov.) illustrates the application to an air conditioning system, an electrode 20 being mounted in the discharge duct 24 leading to an enclosure 25.  The conditioner 26 is equipped with sprays 27 fed from refrigerating equipment 28 to maintain a predetermined dew-point. Control 31 may be responsive to varying water temperatures and regulate the temperature of the spray water and control dampers 32 and 33.  Eliminators 34 at the discharge end remove entrained moisture.  Outdoor air through intake damper 32 and return air from enclosure 25 through damper 33 enter the conditioner for treatment and after conditioning may be augmented by a volume of recirculated air from the enclosure entering through damper 36.  This serves to reheat the conditioned air and reduced its relative humidity. Control 38 regulates damper 36 and controls reheater 39 when required.  Air ionized in the above described manner may also be employed for the treatment of disease or applied to industrial processes, e.g., in the storage of tobacco to control the amount of oxidation.

Abstract: 845,654. Momentum power-storing apparatus. CLARKE, A. V. Dec. 9, 1958 [March 17, 1958], No. 8464/58. Class 10. A flywheel 13, Figs. 1, 2, which drives a generator 62 through chain gearing 54 ... 56, 59 ... 61 and a clutch 58, is energized by a mechanism comprising a driving shaft 22, a cam shaft 25, reduction gearing 34, an electric motor 35 and tension springs 44. The shaft 25, which is chain driven from a reduction gear shaft 33, mounts two cam discs 39, Fig. 2, each of which has two cam projections 40 per face so arranged that a 45-degree spacing ensues. Each disc face is associated with a spring (168) loaded pivotally suspended lever 26 which carries one end of a chain 47 and a sprocket wheel 51, the chain, which is fixed at its other end to the mechanism frame at 53, passing around a sprocket 49 mounted on a shaft 50 fixed to the mechanism framework 27, the sprocket 51, the sprocket 24 of a one-way clutch 23 mounted on the shaft 22 and a sprocket 52 carried at one end of a lever 43. The other end of the lever mounts one end of a spring 44 which is fixed at 45 to framework 46. In operation, cam shaft rotation causes sequential pivotal movement of the levers 26 each driven movement or impulse of a lever effecting tensioning of spring 44 through chain 47 which moves associated clutch sprocket 24 in its free-running direction. Each lever receives two impulses per shaft (25) revolution and on release of a lever by a projection 40 the spring 44 actuates the lever 43 such that the chain 47 rotates the shaft 22 and hence the flywheel through the clutch 23. At the operational speed of the flywheel the motor 35 may be cut out and the springs 44 detensioned through moving notched bars 68, Fig. 2, so that notches 68b engage pins 68a any energy taken from the wheel being replaced by an electric motor 63, Fig. 1, driving through chain gearing 64 ... 66 and a clutch 67. The generator 62 may partially supply the motor 63. In a modified mechanism the springs 44 are replaced by spiral springs coiled in drums coaxial with and secured to the clutch sprockets 24. In another modification each lever 26 moves a rod 79, Fig. 3, which tensions springs 75 mounted between a clutch element 71 and a drum housing 72 attached through a rod to the mechanism frame. In yet another modification having spiral springs coiled in drums each spring is energized from its associated lever 26 through pawl-andratchet mechanism.
