IPC: D05B57/14
Abstract: 133,762. Fairweather, W., (Singer Manufacturing Co.). Oct. 15, 1918. Sewing-machines; lock-stitching by hooks.-Relates to high-speed lock-stitch sewing-machines of the type employing a rotary loopseizing hook performing two rotations for each reciprocation of the needle, and consists in providing a construction of loop-taker and take-up mechanism with the object of increasing the lower-thread capacity of the loop-taker. The loop-taker is of the general form described in Specification 18023/11, and comprises a cup-shaped body 22 supported by arms 21 on a hub 20 secured to the shaft 16, and comprising the usual beak 25 and loop-distending shoulder 26. A raceway 23 is provided for the usual rib on the thread-case, and is closed at one side by the overhanging lip of the removable section 24, which also carries the loopdischarging spur 27 oppositely disposed and nearer the axis of rotation than the beak 25. The thread-case 28 is provided with the usual bearing- rib 30 formed at one end with a loop-detaining shoulder 31. On the side of the case opposite that occupied by the shoulder 31 is an arcuate guard-ribs 32 of less depth than the rib 30, and formed with a shoulder 33 for engagement with the thread-loop at the cast-off position. The looptaker body is cut away at 34 to provide a clearance for the rib 32. The thread-case is formed at its cast-off side with an upwardly and forwardly extending loop-absorbing flange 35, and, at the end of the flange adjacent the loop-seizing position, with a notch 37 engaged, by a stationary finger to hold the case against rotation. The wall of the notch opposite the flange 35 is undercut at 38 to allow passage of the bobbin thread to the work. The thread-case is shifted during each cycle to afford a clearance between the holding- finger and the walls of the notch for releasing the thread-loop by a finger 44 which engages a shoulder 43 on the case, and is carried by a shaft 45 rocked bv crank and link connexions with the feed-lift shaft. Governing needle thread.-The take-up device consists of two spaced disks 60, 62 secured together by a spacing-lug 61, the disk 60 having an arcuate slot 63 in which works a relatively movable thread-engaging pin 64 carried by a vibratory lever 65 which is fulcrumed on the disk and is voked to embrace a slide block 68 journaled on a stationary eccentric 69, whereby the pin performs an accelerated movement in the threaddrawing semi-rotation and a retarded movement in the threaded-slackening semi-rotation. The disks are secured on an extension of the needleactuating shaft and concentric therewith. One, of the radial arms of the loop-taker is provided with a lubricant duct 51 merging into a cavity 52, which may be filled with absorbent material, and is closed by an angular shell or hood 53 open towards the axis of rotation. The cavity communicates with the raceway 23 by one or more passages 54, and lubricant may be supplied either through the mouth of the cavity or through a passage 59 in the looper-shaft bearing and an axial passage 55 with radial branches 57 in the shaft.

Patent GB-475119-A (GB)
Title: Manufacture of new derivatives of aliphatic alcohols
Filed: 1936-05-13
Abstract: Quaternary ammonium salts are obtained by the interaction of an aliphatic alcohol, sulphur dioxide, formaldehyde or a polymer such as paraformaldehyde, and pyridine or an alkylpyridine.  The products are of the type ROCH2N­X, where R is an aliphatic hydrocarbon radicle, N­ is a molecule of pyridine or an alkylpyridine, and X is an anion of sulphurous or pyrosulphurous acid.  Specified aliphatic alcohols are methyl, propyl, butyl, oleyl, dodecyl, hexadecyl and octadecyl alcohols, and these may be single compounds or mixtures such as are obtainable by saponifying spermaceti or by reducing the acids of fats and fatty oils such as coconut oil and palm oil.  As alkylpyridines, mention is made of picolines and lutidines, or use may be made of technical "pyridine bases."  The reaction may be effected by passing sulphur dioxide into a mixture of the other reagents at 70--100 DEG C. in the presence or absence of a diluent, e.g. benzene, toluene or chloroform.  The products derived from the higher aliphatic alcohols form foaming aqueous solutions and are useful as textile assistants. Examples are given of the manufacture of products from paraformaldehyde, sulphur dioxide, pyridine and (1) hexadecyl alcohol, (2) methyl alcohol, (3) butyl alcohol, and (4) dodecyl alcohol.  The Provisional Specification refers generally to the reaction of an aliphatic alcohol with sulphur dioxide, an aldehyde and a tertiary amine.
