Title: Improvements in or relating to tanning of hides or skins
IPC: C14C3/28
Filed: 1931-04-24
Abstract: 377,284. Combination tanning processes. UNITED SHOE MACHINERY CORPORATION, 140, Federal Street, Boston, U.S.A.-(Assignees of Merritt, M. M. ; Middleton, Massachusetts, U.S.A.) April 24, 1931, No. 12136. Convention date, Jan. 12. [Class 76.] A two stage tanning process consists in first treating the hide or skin while in a stretched-out condition with a mineral tanning agent, e.g. a chromium compound or another tanning agent, e.g. formaldehyde, other than a vegetable or animal extract, and after the fibres have set completing the tanning by means of a vegetable tanning agent. The hide &c. is spread out on a supporting surface with the grain side outward, much of the watery content of the hide being removed in the process. The grain surface is then treated by the application of a strong basic chrome liquor and after sufficient time has elapsed to allow the fibres to set the hide is removed and drummed with a vegetable extract. Specifications 24622/01, [Class 76, Leather], and 361,344 are referred to.

Title: Improvements in or relating to the conforming of shoe uppers to the shapes of appropriate lasts
IPC: A43D21/12
Filed: 1953-05-02
Abstract: 750,318. Toe end lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and PULFORD, K. B. May 3, 1954 [May 2, 1953], No. 12220/53. Class 17 (1). The invention relates to toe end lasting- machines having power-operated wipers which are moved to wipe inwardly and are then retracted outwardly, a plate-like member to engage marginal portions of the shoe bottom member during inwiping, and power-operated means which thus engage member 2 with the shoe bottom member prior to the inwiping, so that the member extends between the margin of the upper and the shoe bottom member during inwiping, and later retract the member from the latter position. According to one feature the wipers are moved to wipe inwardly a second time, after member 2 has been retracted. According to a second feature means are provided for impacting the upper margins extending inwardly of the wipers, after member 2 has been retracted. The machine described is generally similar to those described in Specifications 470,749, 482,275, 489,649, 510,086 and 519,775, but instead of tack drivers &c. has means, similar to those in Specification 728,054, for securing the parts by adhesive. The member 2 serves to prevent buckling of the insole margins by the wipers, and to prevent premature adhesion between the upper margins and the insole. The U-shaped member 2 in the form of a thin plate of spring steel is secured to carriers 4, each of which is bifurcated to embrace an arm 10 and carries a pin 12 disposed in a slot 14 in the arm 10, and pins 16, 18 extending into cam slots 22, 24, 26 in supports 20. Forward movement of member 2 is effected by clockwise rotation of arm 10. The operator trips the clutch three times during the operation on a shoe. At the first tripping spreading and retarding fingers move to engage the insole and then to spread the upper outwardly over the wipers, member 2 is swung downwardly into position and held there by plate 9, wipers upwipe, plate 9 is withdrawn, the wipers inwipe, and the machine comes to rest. At the second tripping the wipers are withdrawn until they lie just over the edge of the insole, the member 2 is moved forwardly by rotation of arms 10 until pins 16 lie at the forward ends of slots 22 and pins 18 lie opposite slots 26, the wipers again advance to close partially, arms 10 continue their clockwise movement, carriers 4 rock about pins 16 and pins 18 move up slots 26, and the upper margins extending inwardly of the wipers are compacted by presser plates as the latter are acted upon by part 11 of a pressure-applying member. The clutch is tripped a third time to return the parts.

Title: Improvements in or relating to treatment apparatus and methods for the treatment of textile fibres
IPC: F26B13/10
Filed: 1964-03-23
Abstract: 988,352. Textile treating apparatus. C. VALLS. March 23, 1964 [March 26, 1963], No. 12256/64. Heading D1L. A method of treating textile fibres, in yarn, fabric or flock form, comprises moving them through a first channel, passing fluid through the first channel and in contact with the fibres, and passing fluid from the first channel into one end of of an auxiliary channel and from the other end of the auxiliary channel back into the first channel at a point adjacent the fibres and with a component of velocity at right angles to the fibres. In the arrangement shown, web 5 is caused to travel, preferably upwards, through a treatment chamber through which treatment fluid flows in a downward direction. The flow path of the treatment fluid comprises a main channel 3 leading into a pair of auxiliary channels 1 and 2 and also a central channel 4 through which the web 5 passes. The downstream exits of channels 1 and 2 are so formed that the fluid leaving these channels will have a component of velocity at right angles to the textile web in order to improve the action of the fluid on the web. Preferably the angle between the web and the exit of the channels 1 and 2 is greater than the angle between the web and the entrances of said channels. The channels may be arranged assymetrically and several auxiliary channels may be provided to increase the efficiency of the treatment.

Abstract: 676,485. Vehicular endless tracks. INTERNATIONAL HARVESTER CO. May 22, 1950, No. 12769/50. Class 79(i) [Also in Group XXXII] A joint for an endless track of a tractor or like vehicle compises inner and outer concentric sleeves of substantially equal length, a rubber bushing compressed between them, a bolt extending through the inner sleeve, truncated conical collars located on projecting portions of the bolts with their smaller ends directed outwardly, an expansible split ring coating with each collar, the ring being tapered internally and having a cylindrical periphery to engage a bore in one of a pair of outer or outwardly offset portions of track link element, and a nut on the bolt so that the split rings can be drawn axially together to press the collars tightly against the ends of the inner sleeve and to exert outward pressure in the bores in the element so that the link elements are rigidly connected to the inner sleeve. As shown the track elements each comprise the outwardly offset end portions 22, 22a, and inwardly offset end portions 17, 17a. Bores 18, 18a, in the inwardly offset portions are pressed on to the outer sleeve 19, Arranged between the outer sleeve and the inner sleeve 24 is arranged the rubber bushing 34, relative angular movement between the inner and outer sleeves stressing the rubber bushing. Within the inner sleeve 24 is the bolt 26 and against the ends of the sleeve are arranged the collars 27. The split rings 29 are interposed between the bores 23, 23a, in the outwardly offset end portions 22, 22a, and the peripheries of the collars 27. When a nut 32 is tightened on the bolt 26, the head 31 of the bolt and the nut bear on the rings causing them to engage the collars and thus a rigid connection is formed between the portions 22, 22a and the bolt 26. The joint thus formed forms a readily disconnectible joint between the ends of an endless track. The rubber bushings are inserted when adjacent track elements are in an angular relationship.

Abstract: 603,775. Adjusting radio apparatus. COLE, Ltd., E. K., and KNIPE, A. R. April 29, 1939, No. 12840. [Class 40 (v)] In a two-speed drive for a radio tuning unit, a cord is wound upon or unwound from two pulleys of different diameters over a planet roller which moves into the path of a stop to give a direct drive between the knob and the variable tuning element. As shown, the shaft S of a variable condenser is connected through a pointer support L and a link J to a sleeve M, rotatable about the shaft, carrying a driven pulley R1. A driving pulley R2, of smaller diameter than R1, rotatable about the sleeve M, is held against the condenser mounting by a friction disc E and spring F. A cord U, anchored by a spring to the pulley R1, passes round this pulley, over a planet roller C, on to the pulley R2, round another planet roller C to a point of anchorage on R2. The rollers C rotate about threaded pins B mounted on a spider P which is secured to a sleeve A carrying the knob K and freely rotatable about the shaft S. During slow motion tuning the rollers C rotate around the pins B in opposite directions till one of them engages a stop D carried by the pulley R2, when a solid drive is obtained between the knob K and shaft S. If the knob is then rotated in the opposite direction, fine adjustment is possible till the other roller C has moved sufficiently far. along the pin B to engage the stop D. In a modification, only one planet roller is used, a spring between the pulleys maintaining the tension in the cord.
