Patent GB-189726659-A (GB)
Title: An Improved Automatic Cut-out or Short Circuiting Device for Electric Arc Lamps.
Filed: 1897-11-15
Granted: 1898-02-19
Abstract: 26,659. Holsten, R. W. L., and Elektrische Bogenlampenfabrik Naeck & Holsten GeseHschaft mit beschrõnkter Haftung. Nov. 15. Cut-outs for short - circuiting a lamp should the arc in the lamp fail. The electromagnet e which regulates the arc acts on an armature f fitted with a platinum contact g<1> and connected to one of the terminals. An electromagnet d and resistance h are connected to the other terminal. In normal working the contact g<1> does not touch the contact g of the electromagnet, but should the arc fail the armature is more strongly attracted and makes contact at g, g<1>, so completing a circuit through the resistance h. When the carbons once more approach, the current through the magnet d is short-circuited and the armature falls away.

Abstract: 16,721. Norton, E. Aug. 2. Heating-furnaces for iron and steel &c.-Relates to furnaces for heating sheets and bars preparatory to rolling them into thin sheets for tin-plate or other purposes. Fig. 3 shows a vertical section through the furnace, and Fig. 2 operating- mechanism external to the end of the furnace. In the heating-chamber A' a rotating rack B receives the metal sheets as the radial spaces come opposite the charging-door A<6>, and carry the sheets round the furnace until the door is again reached ; they are then removed from the furnace. The bottom of the furnace is semicircular, and provided with ribs for keeping the plates in place as the rack revolves. The rack is driven externally by means of the toothed wheel b<1>. By means of a clutch D, D<1>, the continuously-rotating drum C drives the shaft E intermittently in such a manner that the rack is stopped as each radial space comes opposite the charging-door. The two parts of the clutch are automatically engaged and separated by the protrusion and withdrawal of a pin working against a cam surface. The arms of the rack may be in double sets and formed hollow for the circulation of air or water for cooling purposes.

Patent GB-189904607-A (GB)
Title: Improvements in and relating to Dredging Apparatus.
Inventor: O'HARA WILLIAM HENRY
Filed: 1899-03-02
Granted: 1899-04-15
Abstract: 4607. O'Hara, W. H. March 2. Dredging; grabs.-Several grabs are arrangad side by side in such a manner that the dumping distance from the grab to the inclined shoot 14 is the same in each case. In the arrangement shown in Fig. 1, three braced jibs 3 are disposed in a stepped fashion at different heights, and are provided with rails 5 on which carriages 6 of the grabs run. The downward movement of the carriage on the rail is limited by stop blocks, pins, or chains which can be regulated to alter the position of the grab. The opening and closing cable 13 and the supporting-cable 12 pass over guide-pulleys to ordinary winding-drums. To operate the grab, it is closed about the mud or spoil by hauling on the cable 13, and the pull on this cable is maintained until the grab is over the shoot. The grab is simply raised until the head 11 reaches the carriage, and then the carriage, with the grab, is hauled up the rail 5. In a modification, the jibs are at the same height, and the lengths of the suspending- heads are varied so that the distance from'the grab in its discharging position to the shoot is the same in each case. If desired, the grabs may be guided by a vertical framework fixed to the boat. The jibs may be arranged to turn on vertical pivots, and may be braced by parallel links.

Abstract: 15,642. Begas, R. July 31. Endless-band propellers.-Figs. 1, 2, and 3 show an endless-band propeller which may be placed in a recess in the vessel's bottom or at the side. Two horizontal shafts 1, 4 each carry a pair of sprocketwheels on which the chains 5, 5 run. Paddies on floats 6, 6, pivoted to the chains at suitable distances apart, are slotted at 8 to clear a guide-rail 10 of I-section on which guide-rollers 9, 9 on the floats run. The guide-rail is much nearer the upper than the lower limbs of the chains, so that, during the forward portion of their movement, the floats move edgewise. When the propellers are arranged at the sides of the vessel, the upper limbs of the chains are usually above the water, but, when the propeller is placed in a recess in the hull, the upper limbs of the chains are submerged.

Abstract: 2019. Barton, J. B., Barlow, A., and Ricketts, J. Y. Feb. 1. Folding.-The fabric, which is laid in layers in any suitable manner on the table a, is folded at the middle, and this again at the middle by apparatus as shown in Figs. 1 and 2. Beneath the table, at the centre, which is here broken away or slitted, are rollers b mounted on spring sliding rods b<1> connected with guide-rods c. Sliding on the rods c is a gripping or drawing device d, consisting of a jaw or plate d'‹ to which are pivoted jaws d<12> which are caused to close on the jaw d<10> by means of a spring sliding plate d<11>, which is connected with the jaws d<12> by the links d<13>. The device is drawn to the base of the rods c by cords passing over pulleys and attached to pivoted levers which are operated by cams, and the plate d<11> is similarly operated to close the jaws d<12>, the device being lifted and the jaws opened by counterweights and springs respectively. The rods b<1>, which carry the rollers b, are similarly lowered and are raised by springs. A corresponding gripping and drawing device having jaws h<13>, h<11> and similarly actuated is adapted to slide horizontally on the rods h<1>. The fabric being in position for folding on the table, the rolls b are lowered, thus permitting the fabric to sag at the middle. The vertically-moving device d is then raised, and the jaws are caused to grip the fabric, which is then pulled down by the device d between the rolls o, thus producing the first fold. The horizontally-moving device may be then used to grip at the middle the fabric thus folded, and draw it between the rolls p, thus producing the second fold.

Abstract: 13,423. Sandberg, G. July 25. Couplings, automatic; buffers.-Fig. 2 shows in plan two carriages coupled together. The central coupling 13 is of the Janney type, with the hook at the proper height above the rails for coupling with existing couplings, and it is connected with the draw-bar in such manner that, on pulling the hook, the disc 8 compresses the spring 10, while on pressing the hook the spring 10 is compressed by the rod 14 and so acts as a buffer spring. The buffer rod 28, Fig. 5, is provided with the sleeve 29, having the cross-section of a square with rounded corners, which is prevented from being pushed out of the buffer box by the pin 33. The sleeve 29 bears against the spring-pressed disc 30.
