Title: Improvements in Apparatus for Forcing Liquids by Direct Steam Pressure.
Inventor: LUHN RICHARD
Filed: 1899-04-27
Granted: 1900-02-24
Abstract: 8881. Luhn, R. April 27. Direct steam - pressure apparatus.-The liquid enters the forcing-chamber A through the non- return inlet a until it reaches the level of the outlet b, when it runs into the float chamber B, the outlet i from which is of smaller area than the inlet b. The float c on rising operates the steam exhaust valve f, p. As the area of the steam valve is greater than that of the exhaust, the immediate effect is to force more water into the chamber B, so producing a decisive movement of the valve and preventing waste of steam. The discharge valve D is below the level of the bottom of the chamber B. An equilibrium pipe K connects the chambers A and B.

Title: Improvements in or relating to Apparatus for Governing Steam Engines.
Inventor: SALKELD JOHN
Filed: 1899-05-01
Granted: 1900-08-01
Abstract: 9068. Salkeld, J. May 1. Brakes.-Relates to means for governing, consisting in the provision of a brake which is applied simultaneously with the actuation of the means for controlling the steam supply. This invention is especially suitable for marine engines in view of the tendency of a marine engine to race when the propeller rises out of water, owing to momentum, or to steam already in the engine. As shown in Fig. 2, the engine shaft A is furnished with a sheave a embraced by a strap brake B. One end of this strap is capable of being drawn up by steam admitted to a cylinder C. The distributing-valve of this cylinder is operated by the governor, hand-lever, or the like by which the steam supply to the main engine is shut off.
Patent GB-189912907-A (GB)
Title: An Improved Feed-water Regulator for Steam Generators.
Inventor: LLOYD JOSEPH CHARLES WILLIAM
Filed: 1899-06-21
Granted: 1900-04-21
Abstract: 12,907. Lloyd, J. C. W. June 21. Feedwater, controlling.-A small pump is arranged to draw from the boiler at the normal water level and discharge into a cylinder A below a looselyfitting piston B having V-shaped notches or grooves b. The upper part of the cylinder is enlarged, and has a return connection to the boiler. The piston is connected to a valve or other device controlling the feed supply. When the water level is above the normal, the pump draws water which forces up the piston B against a spring until the water can escape through the notches and return to the boiler. The rise of the piston cuts off or reduces the supply of feedwater. When the water level falls below the normal, the pump draws steam, which can pass round the periphery of the piston B, through a small hole in it, or through an adjustable connection between the ends of the cylinder, so that the piston falls and the feed is turned on. In the arrangement shown in Fig. 1, the water or steam from the boiler enters the cylinder at H and escapes to the boiler steam space at J. The piston-rod C is connected to a valve controlling the discharge of the feed-pump, either by throttling or diverting it, or to means for controlling the supply of steam to a feed-pump or injector, or for controlling an electromotor or other apparatus for actuating the feed-pump. Fig. 2 shows a modification, the cover of the cylinder and the spring being removed, and the connections to the circulation pump not being shown. In this case the piston is directly attached to a valve L which, in connection with a seating shown separately in Fig. 5, acts when open to divert the supply of feedwater from the boiler. The feedwater enters by one of the branches R, and passes to the boiler through the other one. The water pumped through the cylinder A when the water level is high passes away with the diverted feedwater through the valve L. The steam pumped through when the water is low returns with the feedwater to the boiler. The apparatus is stated to be specially applicable for use with boilers for motor road vehicles.

Title: Improvements relating to the Regulation of Electric Motors and to the Brakes for Electric Railway Vehicles and the like.
Filed: 1899-10-30
Granted: 1900-01-27
Abstract: 21,653. British Thomson-Houston Co., [Case, F. E.]. Oct. 30 Electric locomotives and motor vehicles.- Relates to means for utilizing energy wasted in starting and running resistances used in connection with motors, particularly on electric railways, and to the brakes for the vehicles. The resistance is formed in whole or in part of a current-actuated motive device included as a step of the resistance. In one form, part of the resistance is shown in a series-parallel controller as a rotary motor which drives the air-compressor for the brakes or may perform any other functions. In another form, shown in Fig. 3, the resistance is formed as a solenoid B which draws in a plunger D against a spring D', and thereby liberates the brakes when the controller is thrown on. The spring serves to reapply the brakes when the stops h<2>, h<3> are worked by means of a right and left hand screw spindle operated by treadle gear so as to release gradually or wholly the wedge D<3>, which retains the spring D<1> in the compressed condition.

Abstract: 12. Page, S. E., [Davies, R. W., and Hartman, H. W.]. Jan. 1. Casting.-Relates to apparatus for casting various substances, and especially for casting iron into pigs. The apparatus is of the kind described in Specification No. 19,029, A.D. 1898, [Abridgment Class Iron &c.], and comprises a series of rotary mouldsh, mounted upon the periphery of a horizontally-rotating wheel, or upon any other suitable carrier. The wheel is secured to a central shaft d, and its arms e carry a rail f, which travels upon fixed rollers f<1>; the wheel is driven by means of a pinion g<1> and rack g secured to the arms e. The moulds h, which may have four mould recesses, are each carried by trunnions h<1>, the outer of which carries four radial arms m, which strike against three vertical rods p, p<1>, p<11>, as the carrier rotates so as to rotate the moulds for the purpose of discharging the pigs and bringing the next mould recesses into position for receiving the molten metal &c. The flow of metal &c. is directed by hoods l, mounted upon verticallymovable rods r, which slide within tubes r<1>. The hoods l, which normally fall freely into their lowest positions, rest upon the adjacent moulds and prevent them from overturning during the casting operation and while they are travelling towards the point of discharge. An inclined bar s is provided at the place of discharge, and the rods r travel along this incline and lift the hoods so as to allow the moulds to be rotated by means of the arms m and rods p, p<1>, p<11>, acting successively. Before reaching the rod p<11>, the uppermost mould recess is coated with slurry in the usual way. The pigs &c. discharged from the moulds pass into a receptacle x, having an inclined openwork bottom u and a counterbalanced hinged door v. This receptacle serves to hold a number of pigs &c., which may be cooled to any desired extent by circuits of air ascending through the receptacle, before being dumped into a wagon w.

Abstract: 6831. Klemm, H. A., and Hessel, S. W. March 20. Overedge-stitching machines; ornamental-sewing machines ; multiple-needle machines; double-loop stitching-machines; needle-bars, vibrating laterally; needle-driving.-Consists of improvements in the needle and looper operating mechanism of a machine for making ornamental seams and the like, comprising two parallel rows of stitches with intercrossed threads crossing each other half - way between the rows of stitches. Each needle is fixed in an arm projecting from its needle-bar, and the needle-bars c, d are mounted, respectively, in swinging frames g, m, oscillated in opposite directions from the slotted arm k, q, through links j, s. The frame g is mounted in fixed pivots h, but the frame m in pivots carried by arms o of a shaft p, which is oscillated from a cam 5 through a lever and link, not shown. The needle-carrying arms e, f, are formed to interlock, as shown in Fig. 4, and, by the mechanism described, the needles change places after every stitch, without turning ; Fig. 1 shows one position and Fig. 4 ths other. The needles always descend transverse to the line of feed, and co-operate with a single looper 13. The looper is carried by an oscillating pin 14 mounted transversely on an oscillating shaft 15. The holder 27 of the looper is not exactly radial to the pin 14, so that the looper, in advancing, also rises somewhat. The pin 14 is oscillated from an eccentric through the link 22 and an unequalarmed bell-crank lever, the longer arm 23 of which is longer than the arm 24 of the pin 14. By this arrangement, a quick movement of the looper into and out of the needle loops is obtained.
