Filed: 1926-03-26
Abstract: 251,601. Schmidt'sche Heissdampf Ges. April 28, 1925, [Convention date]. Compound boilers; feedwater, supplying.-In a steam power plant comprising high and low pressure boilers heated by a single furnace and supplying steam to the high and low pressure stages of an engine, water is supplied to the low pressure boiler by an injector operated by steam from a low-pressure stage in greater quantities than it is supplied from the low-pressure boiler to the high-pressure boiler. The high- and low-pressure boilers a, b supply steam to the high- and lowpressure stages of a turbine c. The condensate from the condenser d is fed into the low-pressure boiler by an injector e operated by exhaust and tapped steam from the turbine. A pump h supplies water to the high-pressure boiler from the low-pressure boiler. In a plant comprising intermediate and low-pressure boilers, separate injectors are used for feeding these boilers, water being supplied to the low-pressure boiler from the condenser and to the intermediate-pressure boiler from the low-pressure boiler.

Title: Wire uncoiling means
Inventor: BRIMBLE ROY VICTOR

Abstract: 1,024,896. Unreeling wire. BRITISH OXYGEN CO. Ltd. Jan. 7, 1965 [Feb. 28, 1964], No. 8443/64. Heading B3E. An arrangement for uncoiling wire or like material from a spool by pulling the wire off one end of the spool through a wire guide displaced axially from this end of the spool is characterized in that the wire passes through a bore in a slidable member which can move between the end of the coiled wire and a stop member, the slidable member being biased towards the spool to a limited extent such that it may slide along the wire towards the spool only when that portion of the wire that it surrounds extends at less than a predetermined angle to the spool axis. Wire, e.g. steel wire for use in consumable electrode electric arc welding, is passed from the upper end of a coil 3 on a spool 1, between inner and outer rings 6, 7 resting on the coil end, through a bore in a steel ball 8, through a guide tube 11, over rolls 17, 14, 15, 16 to a straightener and wire feed device. A flanged member 9 secured to the upper end of the spool 1 acts as a stop for the ball 8.

Title: Improvements in the driving and feed mechanism of boring, milling, drilling, tappingand facing machines
IPC: B23Q5/32
Filed: 1937-03-23
Abstract: 474,954. Boring, facing, milling, &c. machines. KEARNS & CO., Ltd., H. W., and KEARNS, H. W. L. March 23, 1937, No. 8500. [Class 83 (iii)] Boring, facing, milling, &c. machines are provided with a supplementary high-speed drive for the main spindle or boring-bar, driven from the main driving gear-box of the machine through light transmission means, separate from the normal more massive transmission means for driving the main spindle subsequent to the main driving gear-box. The main driving pulley 1, Fig. 1, of the machine is rotated at constant speed and drives, through a reversing clutch 3 and four-speed sliding change gears, all housed in the main gear-box e, the pulley 18, through the usual belt arrangement 17 permitting vertical adjustment of the sliding head. The pulley 18 runs loosely on the main spindle or boring-bar d and carries integral therewith a wheel block 22, 23 through which a back gear 24-28 rotates the facing head f. A dog clutch 21 keyed to the'spindle d when moved to the left or right determines respectively whether the spindle is driven directly by the pulley 18 or at slower speeds from the facing head sleeve f<1>. The supplementary high-speed drive of the spindle is obtained from a vertical shaft 37, rotated by bevel gears 35, 36 in the main gear-box, a slidably keyed helical wheel 38 gearing with a wheel 45 capable of being clutched to the shaft 46 which carries a V-belt pulley for driving a similar pulley attached to the spindle. The change-speed gear-box 29 for the work table feed movements, obtained from the output shaft 30, has a shaft 33 which may be driven, for a "cuts per inch" feed, through gearing 31, 32 and clutch 34 from the spindle d, or for a " cuts per minute" feed from the gear-wheel 38 on vertical shaft 37 driving through wheel 39 shaft 40 and bevel gears 41, 42. A rod 54 is connected to the hand-actuated lever 51 for operating the clutch 21 and this is connected to a rotatable disc 55, Fig. 5, having a notched periphery ; the notch 55a permits movement of a hand control 60, Fig. 4, to engage the clutch 34 for either the "cuts per inch" or " cuts per minute " feed, but when the disc is turned so that the notch is out of line with the control rod 60, only the "inches per minute" feed may be engaged, as in this position of the disc a rod 56 connected thereto has moved into a position whereby the control 58 may be operated to engage the high-speed spindle drive clutch 47, the rod 54 is meanwhile in a position corresponding to the neutral position of the clutch 21. Notches 56a and 57a in the rod 56 and the control handle member 57 ensure that the clutch 21 can only be engaged when the high-speed drive has been disengaged. Feeds in cuts per inch are not required when the clutch member 21 is engaged with the pulley 18 so a second notch to permit this is not provided in the disc 55. Specification 375,715 is referred to.

Title: Improvements in or relating to bobbin sorting apparatus
IPC: B65H67/06
Filed: 1945-04-10
Abstract: 593,586. Sorting bobbins. FOSTER MACHINE CO. April 10, 1945, No. 8895. Convention date, July 11, 1944. [Class 117] Apparatus for separating bobbins which have some residual yarn or threads thereon from completely empty bobbins comprises means for conveying a bobbin through a predetermined path of travel, exploring means for searching the surface of the bobbin during said travel to detect yarn (if any) thereon, and means for changing the path of travel, actuated by the exploring means only upon detection of yarn on the bobbin. As shown in Fig. 1, bobbins 11, which have been removed by hand or automatically from a winding machine, are conveyed along a belt 10 and directed by a deflector 30 into a shoot 28 from which they are picked up each by a pair of hooked-shaped hangers 46 attached to two endless chains 41. The chains are driven by sprockets on shafts 42, 17. As the hangers approach the top of their travel, the bobbin comes into contact with feelers 50, Fig. 3, each comprising a curved plate, the underside of which is formed with teeth 51. The feelers are pivoted to operating levers 54, 57 which are pivotally connected to channels 37, 38, respectively, and are linked together by a pivot pin 68, The arm 54 has a depending end 79 and the arm 57 a longer depending end 82. The levers are normally held in horizontal position by means of stops 77. If the bobbin contains no residual yarn the teeth 51 of the feelers 50 slide over the bobbin as it rises and eventually when the bobbin moves over the top of the sprockets 43 one end of the bobbin strikes the end 79 of the arm 54 whereby the bobbin is disengaged from the hangers and flung to the right. If on the other hand the bobbin contains residual yarn, the yarn gets caught in the teeth of a feeler 50, whereby the levers 54, 57 are raised as shown, so that the end 82 of the lever 57 eventually obstructs the bobbin causing it to be flung to the left.
