Title: Improvements in the Methods of, and Apparatus for, Condensing Steam or Cooling Fluids.
Filed: 1901-11-19
Granted: 1902-01-23
Abstract: 23,439. Lake, H. H., [Cosmopolitan Power Co.]. Nov. 19. Condensers; cooling-agents.- Consists in condensing steam or cooling liquids by subjecting them to the action of heatabsorbing vapour in a tubular surface apparatus, first in a light or disseminated form and then in bulk. The invention is applicable for the production of distilled water. In the form of apparatus shown, 1 is a drum with a chamber 2 at the upper part with a perforated bottom beneath which are a number of tubes 5. The steam to be condensed, or fluid to be cooled, is introduced to the chamber 2 by an expanding pipe 3, and flows through the perforations in fine streams among the tubes 3, through which air laden with aqueous vapour is drawn. From the drum 1 the condensed steam or liquid passes into the drum 12, and is further cooled by tubes 13. It is finally withdrawn through a stand-pipe 19. The air and aqueous vapour are drawn through the tubes by an exhauster 10, the admixture of vapour being effected by water jets 7, 15 directed towards the flaring mouths 6, 14 at which the air enters. The efficiency of the system may be increased by the introduction of a small quantity of ammonia, or of carbon bisulphide, into the spray. Cups for containing the ammonia are shown at 22, 23.

Title: Improvements in Self-closing Valves for the Discharge of Liquids.
Inventor: SCHOENHEYDER WILLIAM ANTON GOT
Filed: 1901-12-16
Granted: 1902-03-20
Abstract: 25,687. Sch÷nheyder, W. A. G. Dec. 16. Measured quantities, delivering.-A self-closing valve which can be adjusted to discharge a required quantity of liquid is shown in Fig. 1. The casing D encloses a cylinder A which contains a piston E formed so as to serve as a cylinder for a second piston I on the spindle J. The valve F controlling the discharge from the inlet D' is carried by the piston E which has a small aperture E' in its base. The cylinder A has a loose cover B with one aperture B' which is covered by a disc C with several apertures C' of different sizes. In operation, the handle L is raised and moves a cam K which lifts the spindle and its piston. The small aperture E' prevents much escape of liquid, and so the piston E and valve F are raised. The valve closes independently of the spindle according to the rate at which liquid can pass through the apertures C', B', into the cylinder. The disc C can be rotated to bring an aperture of the required size over the aperture in the cover B. The cover may be pressed downwards by a spring.
Patent GB-190201123-A (GB)
Title: Improvements in Button Hole Sewing Machines.
Inventor: HOUSE WILLIAM MANNING
Filed: 1902-01-15
Granted: 1902-06-05
Abstract: 1123. House, W. M. Jan. 15. Buttonhole-sewing machines; buttonh o l e s, barring.- Consists of a machine for producing a buttonhole having barring-stitches at right-angles to the side stitches. Fig. 2 shows a top plan, and Fig. 3 an underside plan- The feed motion for the side stitching is obtained from a crank-disc E<6> connected to a wheel E<3> gearing with a wheel E<4>, which engages, by means of a fork e', with a pin e<3> in a ratchet-wheel E<2>. The pawl e<1>, which turns the wheel E<2>, is disengaged therefrom during the barring by a ratchet segment e carried round by the wheel E<2>. To ensure that the pawl e<1> shall engage the segment e, a second pawl e<2> is provided, shorter than the first and engaging the segment e only. The needle-bar is vibrated laterally during the side stitching, through a usual block and slotted lever, the position of the block being controlled by a stepped cam F on the wheel E<3> through a lever F<1> and rod. During the barring, the lateral vibration of the needle-bar being stopped by means of the cam F, and the wheel E' being stationary, the work-support is oscillated lengthways of the buttonhole and also fed transversely, by means of two cams N, 0 connected to a ratchet-wheel G<2>. Two pawls g<1>, g, carried on a pawl lever G<1>, are adapted to engage the ratchet-wheel G<2>, but during the side-stitching the pawl g<1> is held out of engagement by a spring H<1> and lever h<4>, h<3>, and the pawl g merely oscillates over the blind tooth g<4>. The rotation of the ratchet-wheel G<2> is started by the engagement of a cam h<5> on the segment e with the lever h<3>, h<4>, thus allowing the pawl g<1> to engage the ratchet-wheel G<2>, which continues to rotate under the action of the pawl g until the latter again engages the blind tooth g'. The cam N by which the barring-oscillations of the work-support are produced, actuates the work-support through a stud l<4> fixed to a slide L carrying, in a slot d<2>, a pin l<3> engaging in a slot in a plate P connected to the plate Q in which slides the work-support carrier E. The plate Q is pivoted on a stud q<3> by means of a block Q<1> and slot q<1>. The barring-feed cam 0 actuates the plate Q through a'stud r. If the cam N is perfectly symmetrical, the barring-stitches at one end of the buttonhole overlap the side stitches, while at the other end they are entirely clear, as shown in Fig. 6. By making the cam N, however, with one of its recesses n<1>, Fig. 8, half the depth of all the others, the barring-stitches partially overlap the side stitches, and to the same extent at each end of the buttonhole.
