Title: Improvements in and relating to the manufacture of rollers for roller bearings
IPC: B24B5/04
Filed: 1922-04-11
Abstract: 202,356. Leon, K. O. April 11, 1922. Rollers and the like, treating.-Rollers are ground to barrel shape by supporting them on edge on a rotary grinding wheel b and oscillating them from side, to side, in apertures in a cage p by the rotary or oscillatory movement of a driving-member 12, which rests on the rollers. The grinding-wheel spindle d is supported in, and adjustable vertically by brackets f, g, which are slidable on the machine frame a by a screw h, and the spindle is driven by a pulley n, through which it can slide, carried in a fixed bracket c. The cage p is carried by a spider frame q secured to a hollow stem r mounted in a bracket s, which is adjustable vertically on the frame a. Inside the stem r is a spindle u having at its lower end an enlarged part V to which are secured an eccentric pin W and a spur-wheel x driven by a pinion y. On the. pin W is an adjustable eccentric sleeve 10 carrying the driving- member 12. By rotation of the sleeve on the pin, the eccentricity of the member 12 with respect to the spindle u may be varied, and when cylindrical rollers are to be produced, reduced to zero; the sleeve and the member 12 are locked in adjusted position by a nut 15. The spur-wheel x and the member 12 may be raised, against the pressure of a spring 16, by a cylindrical rack 17 secured to the spindle u and lifted by means of a pinion 18 and a rack 20 operated by a handwheel 21. The cage p has therein concentric with the spindle u, a number of tapered slots 24, Fig. 4, in which the rollers are placed; plates 25 are fitted to the slots to allow the tilting of the rollers. The edge of the ring 12 is thickened to form a casing for a removable annular block 27, Fig. 4, which has a convex under face contacting with the rollers; spring tongues 29 at the sides of the block ensure that with the return movement of the member 12 the rollers will resume the upright position. In order to increase the grinding pressure, the spindle u may be pressed down by operation of a lever 35. In a modification, the driving-member is prevented from rotating by a pin thereon which engages a slot in the spider frame, and the driving-member is oscillated by means of the eccentric sleeve, which is rotatable within the driving-member. The rollers each bear on a spring-pressed disc, a number of which are mounted in the driving- member. The Provisional Specification describes also a construction in which the surface of the grinding-wheel is convex instead of, or in addition to, the block 27. The eccentricity of the driving- member may be varied by cranks, cams, &c. instead of by the eccentric sleeve. Specifications 201,980, [Class 106 (ii), Dynamometers], and 201,981 are referred to.

Title: Improvements in or relating to packing machines
IPC: B65B19/20
Filed: 1938-04-06
Abstract: 511,616. Packeting-machines. PARRY, F., and MOLINS MACHINE CO., Ltd. April 6, 1938. No. 10525. [Class 94 (i)] The machine inserts into boxes a row or rows of articles transversely to the length-of the rows. The boxes may be fed to the filling position by apparatus such as is described in Specification 511,617. The articles 89, Fig. 2, are fed into the machine by an endless belt 90 over a bridge 95 on to a belt 94. The belt 94 is supported by rollers 112, 139, 152, Fig. 7, so that the upper row is arched, and the row of articles is correspondingly arranged so that the outer end faces converge. The outer face of the leading packet in a row is arrested by a stop 99 and the belt slips beneath the row, thus ensuring contiguity. A pusher 101 then transfers the assembly into position over the box B and beneath a plunger 113, a movable support 108, arched to a shape similar to that of the belt 94, supporting the packets during transference. A backward extension 149 on the pusher stops the feed of further packets by the belt 90 until the pusher is retracted. The plunger 113, which has a concave under surface, descends and forces the assembly into the box. One vertical side of the row is engaged by springs 120, and the other by the rear face of the flap support 12. The ends are engaged by leaf springs 119, Fig. 7, which are forced outwards and move the end flaps d of the box out of the way and form guides to facilitate insertion. If the box is to receive two superposed rows, the first row is forced 'downwards and is supported by the springs and the plunger is given a longer stroke when moving the second row downwards, so that both are inserted into the box.

Title: A process of treating fibrous materials including leather
Filed: 1936-04-15
Abstract: Fatty acids having at least six carbon atoms and containing at least one double linkage which has been subjected to elaidinization, and a strongly hydrophillic group are used in aqueous treating baths for fibrous materials such as textiles and leather.  By "strongly hydrophillic group" is intended a group, other than a carboxylic group, which renders the fatty acid soluble in water.  The water solubilizing, group, which preferably contains sulphur or phosphorus, may be introduced into the fatty acids, for example, by treating the fatty acid with a compound containing a water solubilizing group, e.g. taurine, or by sulphonation.  The elaidinized compounds improve the wetting, emulsifying and detergent properties of the treatment liquids and may be used in association with soaps of elaidinized fatty acids. In examples: (1) a washing agent is obtained by condensing elaidic acid with taurine; (2) a foaming agent is prepared by condensing the sodium soap of linolelaidic acid (obtained from linoleic acid) with ethionic acid; (3) the sodium soap of ricinolelaidic acid is reacted with glycolchlorhydrin and sulphonated; after removal of excess acid and neutralization, a wetting and foaming agent is obtained; (4) the sodium soap of the butyl ether of ricinolelaidic acid is treated with glycolchlorhydrin as in example (3) to give a wetting and foaming agent; (5) ricinolelaidic acid is sulphonated and neutralized.  Specified elaidinized fatty acids which may be used are those containing halogen or ester or ether groups or side chains of the aliphatic, aromatic, alicyclic or heterocyclic series which may be attached by means of carbon, oxygen or sulphur.ALSO:Fatty acids having at least six carbon atoms and containing at least one double linkage which has been subjected to elaidinization, and a strongly hydrophillic group are stated to have detergent and emulsifying properties.  A "strongly hydrophillic group" is defined as a group, other than a carboxylic group which renders the fatty acids soluble in water. The water solubilizing group may be introduced into the fatty acids by esterifying the carboxylic group with hydroxyethanesulphonic acid, or by condensing with taurine. Specified elaidinized fatty acids which may be used are those containing halogen or ester or ether groups or side chains of the aliphatic, aromatic alicyclic or heterocyclic series which may be attached by means of carbon, oxygen or sulphur. The elaidinized fatty acids may be used in association with soaps of elaidinized fatty acids.
