IPC: B61H13/02
Abstract: 106,893. Daglish, E. E., and Lorkin, W. L. July 12, 1916. Driving-gear for winding and paying-out apparatus; overwinding and overrunning preventing. - Relates to winding mechanism particularly for hand-actuated vehicle brakes and comprises chiefly a stop device of the kind described in Specification 26060/12 for limiting the unwinding or releasing movement of the mechanism and an adjustable mounting for the winding drum. The ratchet wheel B<2> is rigid with the operating shaft B and has a projection B<4> which works in a slot F<2> in a loosely-mounted disk F', also provided with a projection F for engagement with a projection E<2> on a loosely mounted cover-plate E'. When the shaft B has rotated through practically one revolution, the projection B<4> reaches the end of the slot F<2> and then moves the disk F'; after a further revolution, the projection F on the disk engages the projection E<2> and rotates the plate E' which permits a third revolution of the shaft, further movement being prevented by the engagement of a projection E on the plate E' with a normallyfixed stop D<4>. To permit of adjustment of the stop D<4> to compensate for wear of the brake blocks or other purpose, a number of sockets therefor are provided in the upstanding parts D<3> of the fixed base-plate D'. A roller bearing B<3> for the shaft is arranged in the boss D of the plate D', on which also is mounted the retaining pawl. The gearwheel C' fixed upon the shaft B has a flange c' bearing upon the drum gear-wheel C<2> to prevent the wheel C' from falling in the event of breakage or detachment of the cotter pin c. The plate G provided with the yoke H for the chain drum C is fixed to the platform partly by the bolts d which secure the plate D<1> and to permit of adjustment of the chain drum to the line of draught of the chain, slots concentric to the shaft B are provided in the plate G for these bolts.

Title: New metal complexes of dyestuffs of the benzene-azo-thionaphthene series
Filed: 1956-04-09
Abstract: The invention comprises chromium and cobalt complexes of dyes of formula X-R-N=N-Y which are free from SO3H or non-complex forming COOH groups and where X is a metalcomplex forming substituent in ortho position to the amino group, R is a benzene residue and Y a residue of a 3-hydroxythionaphthene attached in its 2-position to the azo bridge.  They are made by coupling an appropriate diazotized aniline derivative with 3-hydroxythionaphthene or its -2-carboxylic acid, since during the coupling reaction the carboxy group is removed, and metallizing the product.  Specified diazo components include aniline-2-carboxylic acid and its halo and nitro derivatives and 2-aminophenols containing chloro, nitro, methoxy, alkyl, acetylamino, sulphonamido, which may be N-substituted, and sulphonyl groups and alkyl ethers of 2-aminophenols.  Specified coupling components include 3-hydroxythionaphthene and its chloro, bromo, methyl, methoxy and methylmercapto derivatives and benzo-3-hydroxythionaphthenes.  The 2-carboxy derivatives of the above coupling components may also be used.  Metallization may be effected on the fibre when the metal-free dye is sufficiently water-soluble.  1 : 1- and 1 : 2-complexes may be obtained. Mixtures of dyes may also be metallized in which at least one of the mixed dyes is of the above formula.  Metal complexes which are free from sulphonamido and alkyl sulphone groups are very soluble in alcohols and esters and are therefore used to colour lacquers and, as neutral aqueous dispersions, for dyeing polyamide or polyurethane fibres. Water-soluble metal complexes dye animal fibres from a neutral or weakly acid bath.  In examples which illustrate the preparation of the dyes, and their use in various dyeing and colouring processes, the reactants used are chosen from those indicated above and red, blue, green, brown and black shades are obtained.  Specifications 637,404 and 747,367 are referred to.

Title: Improvements in or relating to coin-freed apparatus
IPC: G07F13/02
Filed: 1927-04-26
Abstract: 294,677. Brecknell, Munro, & Rogers, Ltd., and Dolman, H. J. April 26, 1927. Delivery of liquids.-Liquid, such as petrol, is raised by a manually-operable pump 4, Fig. 2, through a pipe 6 to a measuring-vessel 2 having an overflow pipe 7 to return excess liquid to the reservoir. The pipe 7 may be moved up or down to adjust the quantity of liquid the vessel 2 can contain by a rack and a pinion 9, 10 actuated by a hand-wheel 12. The liquid is delivered through a valve 15 which is operated by a handlever 16 secured to a semi-circular plate 17. When the lever 16 is turned, a rod carried by the plate 17 causes a rocker 20 to engage a lever 22 secured to the prump handle 3, and then a weighted rod 18 is raised by the plate 17 to open the valve, the arrangement being such that the pump is looked when the valve 15 is open. To such known apparatus a coin-freed mechanism 23 is applied so that movement of the handle 16 from valve open position to pump free position and back again can only be effected on the insertion of a coin. The plate 17 is connected by a rod 24 to a vertically slidable plate 29, Fig. 4, carrying a lever 3'7, one arm 39 of which engages a stop 40 normally to prevent movement of the plate 29 and the handle 16, until a coin is inserted, when the lever 37 is turned aside against the action of a spring 40<1>. The Provisional Specification describes also reversible pawl mechanism so that the coin-freed device cannot be returned to its initial position until the delivery valve has been fully opened. The movement of the valve lever may controlled by mechanism such as described in Specification 291,476. The apparatus may also be prodded with change-giving mechanism such as described in Specification 247,396. Price-changing mechanism.-The wheel 12 is locked in adjusted position by a member 66 engaging a knob 26 on the wheel and carried by an adjustable bar 25 pivoted at 60. A cam 61 when the wheel 12 is locked, holds a spring- pressed arm 62 aside, the arm 62 having a nose 65 which, when the wheel is unlocked, engages under the arm 41 of the lever 37 to hold the coin freed mechanism out of action, so that the apparatus may be used without coins. Coin action, with stationary coin forming abutment; coin-discharging mechanism.-A coin 53 after passing through coin testing devices such as described in Specification 275,278, rests on a platform 46 and in a shoot formed of walls 42, 43, and forms an abutment for the arm 41 of the lever 37 thereby causing the lever to rotate as the plate 29 moves down. A stud 52 on the plate 29 engaging in an inclined slot in a plate 47 carrying the platform 46, moves the platform aside to allow the coin to drop. The side 43 of the shoot is pivoted and is moved aside by the platform to ensure the release of the coin. The Provisional Specification describes also means for different quantities of petrol to be supplied for different coins.
