The gears 10 mesh with a large gear 12 which is connected by a sleeve 14 with the drum 16 or outer member of an hydraulic or other variable-resistance clutch. The inner member or eccentric piston 17 of this clutch is fast on a sleeve 24 loose on the shaft 6. A double claw clutch 26 being splined at 32 to the shaft 2, may be engaged alternatively with a clutch end 25 of the sleeve 24 and clutch dogs 27 on the shaft 6. When the clutch 26 is engaged with sleeve 24, the shaft 2 is fast with piston 17. When then a sleeve 21 is moved to close ports 19, Fig. 3, the gearing rotates solid for the highest speed, since the gear 12 and carrier 7 are clutched together. When the sleeve 21 is moved to open the ports 19 partially, slipping takes place so that the drive may be gradually reduced to zero. On applying a brake 36 to carrier 7, the wheel 12 is driven reversely, and this through the variable clutch and clutch 26 drives shaft 2. In addition, a definite low forward speed is effected when the wheel 12 is held by brake 40 and the shaft 6 is connected to shaft 2 by the clutch 26 in the posi. tion shown in Fig. 1.

Title: Manufacture of hydrocyclic-ªÏ-aminomethyl compounds
Filed: 1925-09-14
Abstract: o -Aminomethyl derivatives of hydrocyclic ketones are prepared by catalytically reducing hydrocyclic cyanoketones, and hydrolyzing the intermediate products.  The process is particularly suitable for the treatment of a -cyano derivatives of hydroaromatic ketones, such as camphor, menthone, thujone and pulegone.  The products are basic in character and can be converted into water-soluble salts which possess therapeutic properties.  According to the example, a solution of a -cyanocamphor is treated with hydrogen in the presence of a nickel catalyst.  After the calculated quantity of hydrogen has been absorbed (on the basis of 3H2 per 2 mols. of cyano camphor), the product is filtered, the solvent distilled away, and the hydrochloride of methylenecamphor-camphomethylamine precipitated. The latter is then hydrolyzed, the oxymethylenecamphor formed as by-product removed with ether, and the aqueous solution evaporated to obtain the hydrochloride of a -camphomethylamine.  The properties of the intermediate and final bases are described.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the cyano derivative of cyclohexanone as a starting material; this subject-matter does not appear in the Specification as accepted.ALSO:o -Aminomethyl derivatives of hydrocyclic ketones are prepared by catalytically reducing hydrocyclic cyano ketones, and hydrolyzing the intermediate products.

Abstract: 501,134. Lasting shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation) Aug. 21,1937, No. 22943. [Class 17 (i)] A device for notching or slitting upper margins is applied to a toe-end-lasting machine of the wiper type, and is movable stepwise around the toe portion. A bracket 22 is secured to the usual upward extension of the frame carrying the portable hand tacker 21 and the tack delivery mechanism therefor. The bracket supports a shaft 24 on which slides and rotates a sleeve 28 having at one end a cam surface co-operating with a stud 52 on the bracket. On the sleeve rotates a driven pulley 30 integral with a clutch surface 48 co-operating with a clutch surface on a pulley 26 driving a shaft 34 carried by an arm 32 secured to the sleeve 28. When the arm is pulled downwards the clutch is engaged and the shaft 34 is driven. Secured to this shaft is a bevel pinion 72 gearing with a bevel wheel 74 on a shaft 68, the wheel driving a pinion 76 rotating with a shaft 60. The construction provides a universal mounting for the shaft 60 enabling it to be swung in any direction. The shaft 60 is connected by a universal joint to knife driving mechanism in a handle 80. At the lower end of the handle is a fixed knife 82 shaped to cut a notch, and a movable cutting blade 88 shaped to embrace the knife 82 and reciprocated by a roll 92 on an eccentric stud rotated by a tooth 118 co-operating with an undercut tooth 116 driven slowly by epicyclic gearing. This comprises internal teeth 108 on a sleeve connected to the tooth, a larger ring of internal teeth formed in a housing 112, and a driven rotary member 110 having upper and lower pinions of different diameters gearing with these two sets of internal teeth. The construction gives a large reduction ratio. Normally, the teeth 116, 118 are urged together by a spring 120 ; but they can be separated by a plunger 126 actuated by a finger lever 128 and engaging a cam surface at the top of the driven rotor. Springs 138 separate the teeth to prevent clicking when the finger lever is in action, the under-cut construction of the teeth drawing them together and compressing these springs. Preferably, the notching of the upper margin is done at the conclusion of the upwipe while the wipers are still pressing on the upper but before they advance to wipe the upper margin over the insole.
