Title: Indexing mechanism for automatic multiple spindle screw machines
IPC: F02M7/12
Filed: 1934-09-24
Abstract: 447,747. Lathes. FAIRWEATHER, H. G. C., 65, Chancery Lane, London.- (National Acme Co. ; 131st Street, Cleveland, Ohio, U.S.A.) Sept. 24, 1934, No. 27407. [Class 83 (iii)] In an automatic multi-spindle screw machine such as that described in Specification 410,135 the work turret indexing mechanism is arranged to index the work turret either by the distance between successive spindles or by twice such distance at each operation. Thus a six spindle machine may either be arranged to complete one piece for each revolution of the turret 39 or in cases where the work may be complete at three spindles, two pieces may be completed per cycle. The usual lower cross slides 206, 207, upper cross slide 209, threading slide 131 and central carrier 71 for end working tools are provided. The turret carries a gear 38 engaged by a gear ring 5 to effect the indexing. The gear 5 is operated through a disc 37 having four sets of lugs 49 which coact with a roll carried by the indexing arm 36 on the main cam shaft 30. Studs 3 mounted in the disc 37 and in a member 371 bolted to disc 37 by bolts 37<11>, carry double planetary gears 2, 6, the part 2 engaging external teeth on the ring 5 and the part 6 engaging external teeth on a central gear 7. For indexing the turret through one sixth of a revolution, the disc 37 is secured to the ring 5 by bolts 10<1> while the gear 7 is free to rotate on the frame 8. This renders the planetary gearing ineffective. When an indexing movement of one third of a revolution is required, the bolts 10<1> are removed and placed in the position 10 where they connect gear 7 to the frame and hold it stationary. With this setting of the parts the gear 5 rotates twice as fast as before relatively to the disc 37.

Patent GB-463955-A (GB)
Title: Improvements in the treatment of cellulose ester threads, ribbons, films, fabrics and like materials
IPC: D06M11/38
Filed: 1935-10-05
Abstract: Artificial threads, ribbons, fabrics, films, and like materials having a basis of organic ester of cellulose are locally reserved against alkaline saponification by a reserve composition containing a water-insoluble substance which is converted into a water-soluble substance by the action of the saponifying-agent. The materials are locally saponified by treatment with the saponifying-agent, and subsequent removal of the reserve composition is facilitated.  The reserve may consist chiefly of a solid fatty acid such as stearic, palmitic, lauric, elaidic, and oleic, or other high molecular organic acid such as abietic or other resin acid.  It may contain an addition of paraffin wax or other waxy substance which is unaffected by the saponifying-agent, e.g. chlorinated naphthalene or diphenyl.  The action of the saponifying-agent may result in the formation of a surface film of salt on the reserve or in more intensive conversion, but the salt may be prevented from dissolving owing to the presence of a substance with an ion in common with the salt.  For this purpose, sodium acetate may be present in a caustic soda saponifying bath. The materials may be dyed in the saponification bath which may contain cotton dyes or cellulose ester dyes, or they may be dyed in a separate operation, Cross-dyed effects may be obtained, e.g. the locally saponified materials may be treated with a red cotton dye and a blue cellulose acetate dye to give contrasting red and blue effects.  Materials of cellulose acetate, formate, butyrate, nitrate, mixed esters of cellulose, and cellulose ether-esters, may be treated.  In an example, cellulose acetate yarn is coated at intervals along its length with stearic acid by drawing the thread past a rotating paddle partly immersed in the molten acid. The thread is given a short air-run to solidify the coating and then passed continuously through a hot aqueous solution of caustic soda.  In another example, the saponifying bath comprises an aqueous solution of caustic soda and sodium acetate, and the reserve composition comprises a mixture of stearic acid and paraffin wax.  Instead of caustic soda, sodium carbonate, tri-sodium phosphate, sodium silicate, methylamine, ethylamine, ethylene diamine, and monoethanolamine may be used as saponifying-agent.  Instead of sodium acetate, sodium lactate, tartrate, or chloride may be used to reduce the alkalinity of the bath or the solubility of the product formed by reaction between the saponifying-agent and the reserve. Specifications 332,263, and 332,290, [both in Class 15 (ii)], are referred to.  The Provisional Specification also refers to Specifications 417,220, 429,103, 430,349, 430,350, 430,351, 432,028, and 453,302.
