Granted: 1898-05-14
Abstract: 701. Wainwright, J. T. Jan. 10. Casting.-Iron and steel car wheels are cast of molten metal which has been subjected to the action of a vacuum or exhaust, whereby the formation of blow-holes in the casting is prevented without necessitating the presence in the metal of silicon or other substances which make the wheels brittle. The molten metal thus treated is cast either in a chilled mould for hardening the rim or tyre, or otherwise cast, and the tyre subsequently heated and chilled.

Title: Improvements in Looms for Weaving Tufted Pile Fabrics, and more Particularly relating to Looms for Weaving "Moquette" Carpets of Great Width.
Inventor: TOMKINSON MICHAEL
Filed: 1898-10-27
Granted: 1899-10-27
Abstract: 22,604. Tomkinson, M., and Adam, P., [Skinner, H., and Connolly, F. H.]. Oct. 27. Looms, pile forming and cutting in.-In looms for weaving Moquette carpets and other tufted pile fabrics, the spool-frame carrying-chains G are arranged in pairs, and each pair carries a series of spool-frames g<5> in alignment with those in the other pairs. The chains G are driven by sprocketwheels g, and pass over idle sprocket-wheels g' and curved guides g'. Each spool frame g<5> is held between a pair of chains by spring pawls, which are retracted to shift the frame to the transferrer h by means of tripper arms g<11> on a rock-shaft g<12> actuated by an arm g<13> and connecting-rod g<14> from a cam on the shaft E. The transferrer brings the spool frame into position for the ends of yarn to be seized by a pair of nippers J, and moves upward to draw off the required length for the tufts, which are then severed by a pair of cutting- blades i<1>, i<2>, carried by arms i, i<3> on the shaft I, and operated by cams and connections from the shaft E. When the cutting-mechanism is in its lower position, the blade i<1> rests upon a number of adjustable arms i<25>. A shot of weft is thrown across in the stationary shuttle race C, and is brought into position for beating-up by the lay F by means of arms r on a rock-shaft R. After the weft has been beaten up, the nippers J carry the ends of the tuft threads around it, and then allow them to be brought into position by a hinged comb L, which acts also as temples. The sprocket-wheel g may be driven step by step in either direction, to allow reversed patterns to be made, by two oppositely-acting sets of pawl and ratchet mechanism operated by cams on the shaft E, which carries all the cams necessary for giving the requisite motions to the various parts of the loom.

A wedge-shaped T-piece f is formed on the spindle, and a corresponding piece g on the casing, so that, when the valve is closed, a continued downward motion of the spindle causes the wedges to force the valve discs against the seatings d. The valve discs may be suspended from the spindle by a cradle.

Granted: 1900-08-04
Abstract: 16,083. CuÚnod, H. Aug. 5. Regulating.-Relates to a device for maintaining constant the current produced by a dynamo or other electric generator. A coil n carrying a portion of the current to be regulated is capable of a limited motion in the field of an electromagnet M N of the form shown. The said coil is carried by a lever l, pivoted at o, and provided at its opposite end with a stop-piece b. As the lever moves owing to variation of the current the stoppiece b is brought into the path of one or other of the tappets t<1> and t<2> carried by bell-crank levers r<1> and r<2> mounted on a rocking arm B. By these means one or other of the clicks R<1> and R', also carried by the rocking arm, is brought into engagement with a toothed wheel D, which imparts motion to the regulating-device, e.g., the admission or expansion valve of the driving-engine or the brush-carrier of the dynamo. In order to adjust the lever l, it is connected at one end to a spring c, the tension of which can be regulated by a screw c<1>. After actuating the controlling-device, the lever l may be rapidly returned to its normal position by means of a spring S, connected through an oil or air pump p with a lever E, actuated by the toothed gearing from the shaft A.

Granted: 1900-11-24
Abstract: 24,955. Vining, R. W. Dec. 15. Measured quantities, delivering. - Relates to means for delivering measured mixtures of liquids, such as bovril, from the vessel b and water from the vessel a. The mixing-cock is turned constantly in one direction, a quarter turn at a time, by the handle p, having a spring pawl engaging a ratchet-wheel q. In the position of the cock shown, the measure d fills from the vessel a by way of the ports and pipes g, j, l, f, and the measuring-receptacle n in the cock fills directly from the vessel b. Simultaneously the vessel c discharges by way of the ports and pipes e, m, hand nozzle o, the liquid carrying with it that previously charged into the measuring-receptacle m from the vessel b. A quarter turn of the cock causes the measure c and receptacle m to fill, while the measure d and receptacle n are discharging. The Provisional Specification states that in a modification a slide valve may be used.
Patent GB-190001826-A (GB)
Title: Improvements in Pressure Regulating Devices.
Filed: 1900-01-29
Granted: 1900-11-17
Abstract: 1826. Westinghouse Brake Co., [Westinghouse, H. H., and Clark, F. L.]. Jan. 29. Regulators. - A pressure-regulating device for maintaining a constant pressure in a pipe or vessel, and specially suitable for automatic air brakes for trains, is shown in the Figures. The openings 3, 7 in the casing 1 are respectively connected to the reservoir for compressed fluid and to the pipe or chamber in which the pressure is to be kept constant. The sliding valve 12 normally closes the port 21. The valve is actuated by a loosely-fitting piston 15, which is acted on by the fluid pressure and by a spiral spring 20. A check valve 31 closes the passage 30 leading from the piston chamber 18 to the port 21 of the sliding valve. When the pressure in the chamber 18 is lowered, the pressure on the upper side of a diaphragm 25 is correspondingly lowered, and the diaphragm is raised by the adjustable spring 26 and opens the check valve. The chamber 18 is thus opened, and the pressure therein falls, so allowing the sliding valve to be opened and fluid pressure from the reservoir to pass through the valve to the pipe or chamber.

Abstract: 8818. Lewis, W. J. May 12 Mantelpieces. - Relates to improvements ia the piers or jambs and in the mode of connection of the parts of slate mantelpieces. A pier or jamb a, in one piece and with bevelled or fluted edges a<4>, a<5>, is recessed at c, and a separate plinth d is secured in the recess by bolts passed through holes in the part a and into screwthreaded holes in blocks leaded into the part d. This mode of forming the plinth may be used when the pier is made with one or two side strips f, Fig. 5, secured in place by angle-pieces h, and screws h<2>, engaging holes in leaded-in blocks. In order to connect two strips &c., holes m are milled or otherwise made in the edges of one strip, and a plate n with threaded hole is inserted ; a screw o, passing through a hole in the other strip, is engaged with the screwed hole. By means of a slot leading to the hole, as shown in Fig. 8, the screw o may be made integral with the plate n, and a nut used to secure the parts. The inserted piece n may be of wood, and wood-screws may then be used in place of the bolts o.

Title: Improvements in or relating to Valve Mechanism Especially Suitable for Engines for Compressing Air and Gases.
Inventor: DAW ZACHARIAS WILLIAMS
Filed: 1900-06-28
Granted: 1901-03-16
Abstract: 11,762. Daw, Z. W. June 28. Compressing.-The valves of air and gas compressors and blowing-engines are operated by fluid pressure. The delivery valve 1 is hinged at 5, and is controlled by differential pistons 9, 12. It is opened when the pressure in the cylinder rises high enough to move the piston 12 by acting through the pipe 18. When the piston has passed the entrance 19 to the pipe 18, the pressure in the pipe 17 asserts itself, and closes the valve. The suction valve 23 is opened by the pressure in the delivery chamber 4 acting through the pipes 35, 32 on the piston 29. The pressure is controlled by a slide valve 34, which alternately opens the pipe 32 to pressure and to the atmosphere. The valve 34 is operated in one direction by a piston 41, which is moved to the right when the pipe 38 is uncovered by the movement of the main piston 15 to the left. The valve rod 42 is moved to the left by a piston similar to 41 at the other end of the cylinder 2. The valves are fitted with dash-pots 8, 27.
