Abstract: 19,506. Noel, J. A. Sept. 10. couplings, non- automatic.-To prevent accidental detachment of the pins of shackles for coupling colliery trams and for other purposes, the pins are made of spiral form so that the strain of the drawbar tends to draw them down. As shown, the pin may be of circular cross-section, and is provided with a link and ring, or a swivel handle D, to allow of the rotation of the pin when entering or leaving the shackle. The pin and the eyes of the shackle may also be of oval form, the draw-bar being adapted to engage with the flattened portion of the pin. If desired, the bow D need not be swivelled, but may be provided with a kink E, Fig. 3, which falls over and lies upon the shackle when the bow is released, a stop G causing it to fall always in one direction. In the Provisional Specification an arrangement is described by which, should the pin rise, a hand-ring is drawn into one of a number of serrations in an anchor catch on the shackle bow.

Title: Improvements in or relating to Mechanism for Dyeing wherein the Material to be Dyed is continuously submerged within the Dye without exposure to the Atmosphere during the Dyeing process.
Inventor: GREENWOOD JOHN ROBERT
Filed: 1905-02-11
Granted: 1905-06-08
Abstract: 2873. Greenwood, J. R. Feb. 12, 1904, [date applied for under Patents Act, 1901]. Dyeing.-The material to be dyed is passed repeatedly through the machine described without exposure to the atmosphere except for a very limited time. The mechanism is carried upon a framework 2 which may be inserted or removed at will from the vat 1, upon the edges of which it is supported by the lugs 3. The vat may have usual heating-means. The warp 11 enters the machine from above and passes under and over the rollers 7, 5, 8, 6, 9, then through an oblong opening 12 in the guide-plate 13, preferably of porcelain, and between the pressure rollers 14, 17. Fast and loose pulleys 15, 16 are provided for the driving- band. The warp then passes under and over rollers 22, 23, 24 to the other end of the machine, through the opening 25 in the second guide-plate 26, and is thus deflected to one side so that it may make the next circuit over the rollers 4, 7, &c., passing this time through the opening 27 and over the roller 28 before passing to the rollers 14, 17 and back to the opening 29, whence it passes over the roller 30 before again travelling over the rollers 4, 7, &c., and so on in as many parallel circuits as necessary. The material finally passes from the machine between rolls 14, 17 to enter the usual wash-tank. The number of warps, and the number of return-circuits made by each, may be varied, the capacity of the machine being limited only by the length of the rollers.

Title: An Improved Process for Insulating Electric Wires and Cables
Filed: 1905-04-28
Granted: 1906-01-04
Abstract: 8991. Compagnie Franþaise de l'Amiante du Cap. May 10, 1904, [date applied for under Patents Act, 1901]. Conductors, insulating.-Electric wires and cables are insulated by superimposing on the conductor successive thin layers of fibrous materials, such as cotton, silk, and asbestos, without first coating with adhesive, each layer being separately smoothed or pressed down on to the wire. The layers may be obtained by winding on thin laps of the fibrous material, produced either by means of divider cards such as are used in wool-working, or by the apparatus shown in Fig. 2, in which the fibres pass over the apron d, through the feedrolls e to the pin drum f, whence they pass to one or more chambers g and to the annularly perforated vacuum rolls h, which carry to the outside by their rotation the laps produced over the perforations in the rolls produced by the vacuum. In a modification, the layers are produced by covering the core with an adhesive and passing it through a chamber wherein the fibres are suspended.

Skips of the type provided with a pivoted edge or lip for loading purposes are fitted with a hinged door in the bottom, which is connected to the hoisting-chain by depending chains adapted to be engaged by bolts on the side of the skip to lock the door. The pivoted lip is connected to tbewinding- rope and is also connected through a swivel to a second set of chains for actuating the locking- bolts. Fig. 3 shows a skip 1 having a pivoted lip 3 and a hinged door 6. Chains 7, 8 connect the pivoted lip and the hinged door to the winding- chain 2, which passes through the hollow swivel 16. The chain 18 passes from the winding-drum and is connected to the inside member of the swivel, the outside member being connected by the chains 9, 10 to the pivoted lip and locking-bolts respectively. The locking-mechanism is shown in Figs. 4 and 5, the chains 10 operating levers 11 which engage bolts 12 inside the skip by means of slots 13. The bolts 12 pass through the links of the chain 8 and engage projections in the skip wall. The levers are arranged to keep the door locked under normal conditions by their own weight. During the hoisting operations, the chains 2, 18 are both maintained in tension by being hauled up at the same rate, thus keeping both lip and door closed. On reaching the unloading posi ion, the chains 2, 7, 8 are slackened, thereby throwing the whole weight of the skip on to the chain 18, which transmits it to the chains 9, 10 and thus unlocks the hinged door and discharges the load.

Abstract: 6614. Stewart, S. B. March 20, 1905, [date applied for under Patents Act, 1901]. No Patent granted (Sealing fee not paid). switches.-Relates to an improvement upon the electro-magnetic circuit-breaker described in Specification No. 19,572, A.D. 1904, for electric railways or otherwise where it is required to be operated from a distant point. The switch has three pairs of contacts in parallel, actuated, in such a way as to close in order, by a solenoid in a shunt 'control' circuit, and is provided with blow-out and overload tripping-coils in the main circuit, and an additional tripping-coil with hand-switch and adjustable resistances in another branch circuit. The various parts of the switch are supported by an iron framework composed of heads 11, 12, Figs. 1 and 2, united by bolts, and side pieces 15. The actuating-coil 14, on the closing of a handswitch 70, Fig. 6, lifts the core 17, the lower end of which is pivoted to a lever 19 carrying the main contact-brush 21 and the auxiliary spring contact 22 successively against the fixed contact 23. A carbon block 27 butts against the plate 23, both being carried by a block 28 of conducting-material, and receives the third movable contact 26 carried on a separate arm 25, the other end of which is joined by a flexible conducting-strip 46 to a portion of the metal framework. Owing to the greater leverage, circuit is first completed through the contact 26. An intermediate bent lever 42, pivoted at 43, is also raised by the cross-head 18, and, by pressing the arm 25 through a helical spring 45, keeps the contact 26 ' on' until the others have fallen a certain distance. A toggle 47, 48 straightens, and holds up the switch after closing. The toggle is adapted to be tripped by the rise of the armature 53 of an overload magnet 54. A spring 74 and screw 58 enable the apparatus to be set to respond to different overloads as desired. Another coil 59, in series with a hand-switch 72, Fig. 6, and adjustable resistances 65 carried at the side of the metal framework of the switch, or in any other desired circuit, controls an armature 60 adapted to lift the armature 53 and trip the circuit-breaker. A blow-out coil 35, Fig. 6, placed behind a flange of the contact-block 28, Fig. 1, acts upon pole-pieces placed outside the walls of an arc shoot 29 enclosing all the contacts.

Title: Improvements in or relating to Brake Mechanism for Railway and other Vehicles.
Inventor: BROWN HARVEY EZRA
Filed: 1906-05-16
Granted: 1907-05-16
Abstract: 11,501. Brown, H. E. May 16. Brakes.-Relates to railway-vehicle brake mechanism of the kind described in Specification No. 2U23, A.D. 1905. The tangential pull of the brake blocks, instead of being used to oppose directly the pull exerted by the brake cylinder as described in the above-mentioned Specification, is arranged first to lock the pull-rod positively against further movement, and then to act upon the intermediate mechanism in such a manner as to withdraw the blocks slightly from the wheels. In the arrangement shown in Fig. 1, the blocks e are suspended by links f from a lever c, which is normally held in fixed relation to a bracket d by a spring a, and is capable of turning about one or the other of two fulcra c<1>, c', according to the direction of movement of the vehicle, when the tangential drag on the brake shoe is sufficient to overcome the force of the spring a. When the lever c moves, a square spindle h, carried by it, releases a pawl h<2>, Fig. 2, and allows it to engage ratchet teeth h<3> on a bar connected to the brake cylinder or other motive power, thus preventing an increased application of force to the blocks. In order to provide for a reduction of brake pressure if the drag continues to increase, the truss beam e for the blocks e is extended into a plate e', which is suspended at e<2> by a link e<3> and is formed with a doubly inclined cam-slot e<4>, which is engaged by a roller e<7> on the end of the usual brake lever e<5> operated by the pull-rod e<8>, the lever being suspended by a link e<6>. The increased drag of the brake shoe causes the plate e<1> to turn about the point e' and to bring the roller e<7> into one of the inclined parts of the slot e<4>, thus causing a slight separation of the brake blocks. In another arrangement shown in Fig. 6, the block e is carried by two small elbow levers g, g', pivoted' to the brake beam at points g<2>, g<3>equidistant from the centre of the wheel, and acted upon by springs g<6>, g<7> to keep the block in a fixed position relatively to the brake beam until the drag exceeds a certain limit. When this limit is exceeded, the block moves through a circular arc and acts first through a connexion i<1> upon mechanism for locking the pull-rod against further movement, and next to reduce the pressure on the blocks by lessening the distance between the beam and the block measured in the direction towards the wheel. The locking-mechanism in this case consists of a ratchet bar i<4>, Fig. 8, and a pawl i<3> actuated by a cam bar i<2>, which is moved in one direction by a spring and in the other by the connexion i.

Granted: 1906-11-01
Abstract: 12,554. Atkinson, W., and Smith, J. May 30. Enamels; enamelling; pottery.-Surfaces of metals, such, for example, as iron, steel, copper, &c. are coated with glass, porcelain, or the like, the process being also applicable for pottery and like surfaces. The article to be coated is first cleaned, which may be done by washing with acid and heating, and a flux is then applied. This flux, in the case of wrought-iron or steel articles, consists of white opal cullet 130 parts, sodium bicarbonate 20 parts, and boric acid 12 parts. For other metallic surfaces, such as those of cast iron, the proportion of the same ingredients are 130, 25, and 13 parts respectively. These materials are melted together, run into water, reduced to powder, and ground with water into a paste. The flux, after being applied, is allowed to dry, and the article is fired or baked. White opal cullet or pure flint or soda glass formed into a paste in the same manner as the flux is then applied, and the article is dried and afterwards fired at a high temperature. A second coating of glaze may be applied. Porcelain sherds or waste porcelain may be used in the same way as glass, with the exception that, instead of being fused, it is heated to redness before being thrown into water.
