Title: Improvements in or relating to machines for applying taping to sheet material
IPC: A43D43/06
Filed: 1927-05-09
Abstract: 272,183. United Shoe Machinery Corporation, (Assignees of Osgood, W. P.). June 7, 1926, [Convention date]. Seams.-A machine for flattening stitched leather seams, such as the back seams of shoe uppers, and for adhesively applying finishing tape comprises a roll 8 over which the work w is fed. A pressing and feeding member 9, secured to a carrier 11, receives compound motion from an eccentric 13 on a drive shaft 14, the carrier 11 rocking about a fixed stud 16 which slides in a carrier slot 15. The work w is fed through a guide 18 which is formed with a groove 21 to receive the seam ridge. The tape is fed under lips 24 of guides 22, 23, Fig. 12, a holddown member 28 positioning the tape to pass under the lips 24. A tension-foot 29 yieldingly presses the tape on to the guide 18 in front of the lips 24, the foot 29 being carried by a pivoted arm 30 which has a guiding slot 35 for the tape 7. The active face of the member 9 is curved to the roll 8, and is formed with a seam-receiving groove 37, Fig. 11, which is shallow at the entering end 38, and which deepens and widens towards the end 39. The underside of the forward part of member 9 is corrugated. When the forward end of the member 9 moves downwardly to contact with the work the end 38 of the groove engages the portion of the tape which rests on the seam-ridge, the pressure of the member 9 flattening the seam. The member 9 is electrically heated to soften the adhesive on the tape. As the work comes under the heel 40 of the member 9, the flattened seam is relieved from pressure in the portion 39 of the groove 37, the heel 40 pressing the edges of the tape at sides of the groove. The tape. 7 is fed over linked rolls 44, 48, the roll 48 being rocked with the carrier 11, the link 43 which carries the roll 44 being rocked in the opposite direction to draw a length of tape from the source of supply. The subsequent movement of approach of the rolls feeds the tape to the machine. Specification 220,502, [Class 100 (i). Feeding and delivering webs &c.], is referred to.

Title: Improvements in and relating to methods for the introduction of nh groups into organic and inorganic compounds
Filed: 1932-04-29
Abstract: Monofluoramine, produced by the electrolysis of ammonium bifluoride is used for the conversion of ammonia and its organic derivatives into hydrazine.  Examples indicate the preparation of hydrazine by passing monofluoramine into aqueous ammonia in the presence of glue or gelatine and its isolation as the sulphate.ALSO:The NH2 group is introduced into ammonia, its organic derivatives and phenols by bringing them into reaction with pure dry oxygen-free monofluoramine if desired diluted with a dry inert gas such as nitrogen.  The monofluoramine is produced by the electrolysis of molten ammonium bifluoride at a temperature of about 120 DEG  C. using a current density of about ,02 amperes per square centimetre.  Hydrazine, phenylhydrazine, their derivatives and homologues are obtained from ammonia or organic amino compounds and p-aminophenol or dioxydiphenylamine is produced from phenol.  In examples (1) fluoramine is led into an aqueous solution of ammonia containing glue or gelatine and the hydrazine produced is precipitated as the sulphate.  (2) Fluoramine is passed into aniline and the phenylhydrazine formed is obtained as phenyl-glucoseosozone.  (4) Fluoramine is passed into an aqueous suspension of aniline and the phenylhydrazine is obtained as the phenylglucoseosozone by treatment with sodium acetate and glucose.  (6) Fluoramine is passed into an aqueous suspension of phenol to obtain p-aminophenol.  The Specification as open to inspection under Sect. 91 referred generally to the use of halogenamines for the introduction of the amido group into inorganic and organic compounds and for the sterilization of water and disinfection of materials of all kinds. Aldehydes were converted into aldoxines, benzaldehyde into benzalfluoramine, anisaldehyde into methylamylaldehyde, benzyl chloride into the amide of benzoic acid.  Other compounds that could be treated include compounds containing hydroxy groups, ketones, and acid chlorides. This subject-matter does not appear in the Specification as accepted.ALSO:The Specification as open to inspection under Sect. 91 refers to the use of halogenamines such as monofluoramine for the sterilisation of water.

Abstract: 841,506. Tyre spreaders. SUPER MOLD CORPORATION OF CALIFORNIA. April 22, 1958 [May 31, 1957], No. 12765/58. Class 144 (1). A mobile tyre spreader for inserting tyres into band-tyre retreading moulds comprises a frame 1 mounted on wheels 5, 6 and carrying a vertical support 8 for a vertically adjustable bead spreading means in the form of two circular coaxial radially expansible bead-engaging chucks 23, 24 which are axially separable by fluid-operated power means to effect tyre spreading, the radial expansion of each chuck 23, 24 being effected by means which will maintain it only in its fully expanded or contracted positions but which is adjustable to pre-set the fully contracted size. As shown in Figs. 1 and 2, the vertical support 8 is of inverted U-shape and comprises channel-section uprights serving to guide a carriage 19 supporting the power cylinder 20 of the tyrespreading chucks 23, 24. The carriage is vertically adjusted by a cable 13 passing over pulleys 16, 16 and operable by a double-acting fluid-operated cylinder 18 on the support 8. The spreader cylinder 20 has a neck 22 to which the chuck 23 is secured, the chuck 24 being secured to the piston-rod 21 which slides axially through the neck 22. The chucks are identical and each comprises peripheral beadengaging segments 30 supported on telescopic radial spokes 28, 29 from a hub 25 and urged radially inwardly by springs 31. Each segment 30 has a headed stud 38 to engage in a selected one of three radially-offset notches 37 formed in the outer end of a rigid arm 35 which is pivoted at its inner end to a ring 33 rotatable on the hub 25. Each notch 37 determines a contracted radial position of the associated segment 30, Fig. 3, the arms 35 in such position being disposed at a substantial angle to the radial determined by a predetermined angular position of the ring 33 on the hub 25. The ring 33 is rotatable between two stops 40 which respectively determine the said contracted position of the segments 30, and the expanded position in which each arm 35 passes slightly over centre, Fig. 5. Rotation of the ring 33 is effected manually by a radial lever 42, the lever 42a of the chuck 24 being short enough to permit passage of the contracted chuck into the tyre. In an alternative arrangement, for use with small tyres, the fiame comprises a wheeled spider supporting a vertical tube which receives a screw-threaded spindle directly supporting the spreader cylinder, the spindle being vertically adjustable in the tube by a hand wheelnut bearing on top of the tube.

An odometer comprises a trip counter and a total counter, each counter having a plurality of drums, a first member for supporting the drums of said trip counter, a second member in axial alignment with the first member for supporting the drums of said total counter, and friction coupling means for connecting said two members together so that when the second member is driven forwardly the first is also driven through the friction coupling, but when the first member is driven in the reverse direction the second member is not driven. The total counter wheels or drums 6-10 are mounted on a shaft 1, Fig. 1, and the trip counter wheels 3-5 are mounted on a sleeve 2 on the shaft 1. Friction discs 12 are located between the drums of each counter. A spring 11 urges the drums to the right so that the drum 3 bears against a roller 15 on the sleeve 2 which has a horizontal slot 20, Fig. 3a, and is split at 21, Fig. 3. A pin on the roller 15 enters the slot 20. A cable 16 is coiled round the roller 15, Figs. 1 and 2, and is attached at one end to a coiled spring 18. Each drum comprises a plastic central portion 23, Fig. 4, to which is fixed one or both of the cheeks 24a 24b. The cheek 24a has a single cam tooth and the cheek 24b has ten ratchet teeth. The cheeks 24a, 24b co-operate with curved blades 50 for transfer in known manner. The ratchet teeth of the discs 24b of the total counter drums are so shaped, Fig. 8, as to be locked, against rotation in either direction, by the blades 50 but the ratchet teeth of the cheeks 24b of the trip counter, Fig. 9, are shaped to allow reverse rotation of the trip counter for zeroizing when the free end of the cable 16 is pulled. In a modification (not shown) the cable is attached to a gear which meshes with a pinion on the sleeve 2.
