Patent GB-189720761-A (GB)
Title: Improvements in Internal Combustion Engines.
Inventor: ROOTS JAMES
Filed: 1897-09-09
Granted: 1898-08-27
Abstract: 20,761. Roots, J. Sept. 9. Gas and e x p l o s i v evapour engines, igniting in. Ignition is effected by compressing a charge highly in a small cylinder, which at the proper time communicates with the motor cylinder; the invention constitutes an improvement on that described in Specification No. 2138, A.D. 1896. The Figures show arrangements for four-stroke cycle engines. In that shown in Fig. 1, assuming the charges to have been ignited in the cylinders C and A, the pistons move downwards together, when the piston D has descended so that its port G coincides with the port F, the piston B expels the exhaust through the port F, and as soon as the port F is closed the piston B makes its suction stroke, drawing in a charge through the valve E and then compressing it in the cylinder A ; meanwhile the piston D compresses the charge in the cylinder C sufficiently to ignite it, so that when the port H opens the flame is transmitted to the cylinder A. At starting an igniting-tube J is used which is situated in the vaporizer K in oil engines. In the arrangement shown in Fig. 5, the piston D passes beyond the port I to compress and fire the charge, and opens it to the cylinder on its down-stroke, while the piston B is at the end of the up-stroke. The piston D carries the gas supply valve W. The valve is operated by a cross-grooved cam Y, Fig. 5A. The igniter may be used with an ordinary exhaust valve. In two-stroke cycle engines the valve D moves almost synchronously with the motor piston B, which compresses the charge at its lower end and uncovers an exhaust port at the end of its down-stroke, when the compressed charge enters through the valve E and port I.

Title: The Manufacture or Production of Sulphinic Acids of the Aromatic Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1897-10-07
Granted: 1898-08-13
Abstract: 23,047. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Oct. 7.

Title: Improvements in Bronzing Machines.
Inventor: EMMERICH RUDOLPH FRANK
Filed: 1897-12-04
Granted: 1898-02-05
Abstract: 28,701. Emmerich, R. F., and Vonderlehr, F. Dec. 4. Bronzing.-A sectional elevation of a bronzing- machine is shown in Fig. 2, and a plan of bronzing- pads and their actuating-mechanism in Fig. 12. The sheets to be bronzed are fed from a table C to a cylinder B provided with a longitudinal trough b<2> for containing the gripping-mechanism, which comprises a gripper plate e<1> carried by arms e secured to a shaft E. One edge of the plate e<1> is normally pressed against a suitable seat b<3> on the cylinder B by means of a spring-controlled arm connected to an arm on the shaft E ; the opening of the gripper is effected by means of a pin fitted upon the machine framing so as to strike a cam attached to the shaft E. The bronze is supplied from a hopper G to a rotating roller g<1>, which transfers it to a roller g<2> rotating in the same direction as the roller g<1> ; the roller g<2> bronzes the sheets. The sheet is next rubbed by means of revolving pads j<8> mounted upon a carriage j<2>, upon which is mounted a shaft J. The pads, covered with felt, fur, or other suitable material, and of the form shown in Fig. 12, are mounted in pairs upon shafts rotated by worm-wheels j<16> and worms j<17>;< >the carriage j' and shaft J are reciprocated longitudinally by means of a worm j<5> and a wormwheel connected to the machine framing by a rod. Superfluous bronze is removed by an adjustable roller L provided with an adjustable scraper 0, and the bronze thus removed passes through a reciprocating sieve N into a hopper provided with a rotary conveyer q. When the sheets are about to be released from the cylinder B, a cam-plate f<4> on the framing acts upon an arm f<3> mounted upon a shaft F, Fig. 2, which carries arms f, furnished with pins f<1>, adapted to pass through holes in the seat b<3>. In this way, the sheet is lifted from the surface of the cylinder. The bronzed sheet is delivered to a board S by means of a delivery roller P and drawing-rollers R, R<1>, to which the sheet is directed by the action of hooked stripping- bars t mounted upon a bar T, and engaging with curved guiding-plates u secured to a bar U.
Patent GB-189728888-A (GB)
Title: Improvements in Milking Apparatus.
Inventor: SHIELS ALEXANDER
Filed: 1897-12-07
Granted: 1898-12-07
Abstract: 28,888. Shiels, A. Dec. 7. Cow-milkers.-Relates to apparatus for use with pulsating vacuum machines such as are described in prior Specifications by the applicant, e.g., No. 8325, A.D. 1892, and No. 9273, A.D. 1896. The principal object of the apparatus is to prevent the milk from surging backwards and forwards in the pipe connecting the teat cups and the milk pail. Fig. 5 shows the pulsator in section. It consists of a cylinder 1 open at the bottom and provided with three branch pipes, viz., a milk and vacuum pipe 16 and an air admission pipe 17, both of which are connected by flexible tubes to the teat cups, and another pipe 21 which leads to a spring-regulated air admission valve. A plunger 5 works in the cylinder 1, and is reduced at the point 5<a> to form a passage between the pipes 21 and 17. A groove or duct 30 connects the passage with the vacuum space below the plunger. The plunger 5 is reciprocated so as to allow of the intermittent admission of air through the pipes 21 and 17 to cause the required pulsation in the teat cups, and the plunger is made of such a length as to cut off the pipe 16 from the vacuum in the milk pail while the air is being admitted. The pulsator is secured on a base-plate 2 which fits with an airtight joint into the top of the milk pail. The plate 2 also carries a vacuum motor or the like for operating the plunger 5 by means of the link 14. The motor may be of the character described in Specification No. 9273. A.D. 1896, or of any other form. The pulsator and motor are enclosed in a casing mounted on the plate 2 and provided with a handle. The motor may be driven by the vacuum in the milk pail, suitable connections being made for this purpose through the plate 2. A ball valve is arranged in the pipe connecting each milk pail with the main vacuum pipe, so that, if, through any cause, the vacuum in the main vacuum pipe is destroyed, the milk pails are all automatically cut off to prevent the vacuum in them from being destroyed.
