Title: Improvements in and relating to the Manufacture of Abrasive materials, known as "chilled-iron-shot" for Industrial Purposes: also in Machinery, Apparatus and Plant therefor
Inventor: PEARSON JAMES TOWNSLEY
Filed: 1902-02-18
Granted: 1902-08-14
Abstract: 4081. Pearson, J. T. Feb. 18. Sawing stone &c., metallic grit for. Relates to the manufacture of metallic globules or grit such as are described in Specifications No. 9617, A.D. 1887, and No. 3348, A.D. 1891, [Abridgment Class Iron &c.], for use instead of sand in sand- blast and for use with saws for sawing and polishing stone, marble, granite, &c. In a cupola a there are placed old common cast-iron domestic ovens, boilers, &c. with a small amount of pig iron and heavy machinery and scrap metal together with a small percentage of spiegeleisen. To this 10 per cent. of pulverized aluminium is added in the mixer b. The molten metal runs from the mixer b down the channel g, and, as it leaves the end thereof, is acted on by a jet of steam from a nozzle i which atomizes it and forces the particles through the cone-shaped nozzle o into the small chamber n. This chamber is about one three-hundredth part of the usual size and becomes entirely filled with steam to the exclusion of air. The bottom of this chamber is filled with water. The particles pass over the partition W<1> to the conveyer u, which lifts them to the drying-chamber x heated by the flue y from the cupola. The par- ticles are moved along the floor of the chamber by scrapers a<2> on an endless travelling chain a<1> which delivers them to the pipe b<2> leading to a sifting- apparatus. The steam and floating slag &c. pass through holes p to the tank Q, from which water is pumped and returned to the chamber n.

Title: Improvements in or relating to Driving, Free-wheeling and Braking Mechanism for Velocipedes and the like.
Inventor: RILEY VICTOR
Filed: 1902-10-06
Granted: 1903-09-17
Abstract: 21,689. Riley, V., and Riley, P. Oct. 6. Brakes; clutches; driving - mechanism. -A free-wheel and back-pedalling brake mechanism for bicycles and other velocipedes &c. comprises a pawl cage 16, having a limited rotary movement relatively to the sprocket-wheel, and a brake, the band 41 of which, fixed at-one end to one of the curved arms 40, is adapted to be expanded into frictional contact with the flanges 35 of the hub. The cage carries two sets of oppositely-directed pawls 19, 20 actuated by the springs 24, 25 and provided with projections 29, 30, which, by engagement with slots 13, 14 in the sleeve 11, hold the pawls out of action. The springs 25 are stronger than the springs 24, and in the rest position, the pawls 20 are held in engagement with the teeth 27 on the sleeve 12. The springs 25 also force the studs 30 back against the slots 14 bringing the slots 13 against the studs 29 and so closing the pawls 19 down against the action of their springs 24. On forward-pedalling, the pawls 20 first drag in the teeth 27, and, as the sleeve 11 turns forwards, the slots 13 tend to leave behind the studs 29, and the driving-pawls 19 are raised by their springs into engagement with the teeth 26 in the hub 4, the driving-pins 15 on the collar 5 picking up the pawl-carrier 16. The forward rotation of the sleeve 11 relatively to the carrier causes the slots 14 to act on the studs 30 and draws the braking-pawls 20 down clear of the teeth 27. To increase the dragging effect, springs 44 may be introduced, and the springs 25 need not then be stronger than the springs 24. In free-wheeling, the parts assume their rest position and the hub rotates free of contact with the closeddown pawls 19. Backward pressure on the pedals is transmitted to the sleeve 12 through the pawls 20 and teeth 27, and the backward rotation of the sleeve causes the flat faces of its end to become turned, so that, through the projection 42 or the rollers 43 on the arms 40, the band 41 is expanded into contact with the hub, and braking occurs. In wheeling the machine backwards, the hub rotates without disturbing the mechanism.

Abstract: 25,839. Spooner, A. F., [Boudreaux, L., and Verdet, L.]. Nov. 24. Horizontal engines, general arrangement of; independent engines driving same shaft; cylinders; pistons.-Relates to steam, compressed-air, and like engines in which a stepped piston reciprocates in a correspondingly-stepped cylinder. Fig. 4 shows an engine having a piston p, of three diameters, which drives a transverse crank shaft by means of a connecting-rod, jointed near one end of the piston. The engine may be used as a compound or multiple-expansion one. In one modification, the piston has hollow tail rods, working through open-ended extensions of the cylinder. By this means, air or water is circulated for cooling- purposes. The connecting-rod may be jointed to one of these tail-rods, instead of to the piston as shown. In another modification shown in Fig. 6, the connecting-rod is jointed to a rod t fixed transversely in the piston. In this way, several engines may be arranged to drive one shaft.

Title: The Manufacture and Production of New Derivatives of the Anthraquinone Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1903-05-04
Granted: 1904-03-03
Abstract: 10,074. Newton H. E., [Farbenfabriken vorm. F. Bayer & Co.]. May 4. Dyes, artificial.-New products of the anthraquinone series are obtained by heating quinizarin with solutions of salts of weak acids, such as carbonates, bicarbonates, phosphates, acetates, borates, or the like. The reaction takes place at a relatively low temperature. Two different bodies are produced ; the first, which is but sparingly soluble, is principally obtained on heating to a moderate temperature, and the second, which is nearly insoluble, is principally obtained on heating to higher temperatures. In an example, quinizarin is heated to 120‹ C. for 6 hours with sodium carbonate. After cooling, caustic soda lye is added, and the mixture is heated to the boil for a short time, the mass turning blue. The second product is then filtered off, and the first subsequently precipitated by acidifying. The latter is filtered off, dried, and recrystallized from nitrobenzene. The second product is purified by treating its sodium salt with acids, and recrystallizing from quinoline.

Title: Improvements in Apparatus for Testing Spectacle and other Lenses and Prisms.
Inventor: HAMILTON FRED
Filed: 1904-05-13
Granted: 1904-06-30
Abstract: 11,069. Lake, H. H., [Hamilton, F.]. May 13. Spectacles; lenses. -Relates to apparatus for testing cylindrical and prismatic spectacle lenses. A transparent circular disc A, with a graduated edge, is mounted to rotate in a frame H carried by a standard I. This standard is fitted with a peep-hole g at the top, and at the bottom with a white card ruled with rectangular lines N, O. The disc A is also marked with rectangular lines a, b. Preparatory to testing a cylinder, the card L and disc A are adjusted until, as seen from g, the lines N, 0 lie behind the lines a, b. The lens to be tested is then placed on the disc A which is rotated until the lines N, 0 and a, b again coincide. The inclination of the axis of the cylinder to the axis of shape can then be read off. Neutralizing-lenses may be placed in frames J, K. For testing prisms, the lines a, b are graduated in millimeters. The lens to be tested is placed on the disc A, and its spherical and cylindrical components neutralized. The displacement of the point d, with respect to the print P as seen from g, is a measure of the prismatic power, the rectangular components of which can be read off on the graduated lines a, b.

Title: Improvements in Clinical Thermometers.
Inventor: HICKS JAMES JOSEPH
Filed: 1904-06-16
Granted: 1905-04-20
Abstract: 13,642. Hicks, J. J., and Mills, B. J. B. June 16. Thermometers.-To obviate the necessity for shaking a clinical thermometer in order to re-set the index, it is made with a bulb at each end and with separate scales reading in opposite directions In the construction shown in Fig. 1, a "knife- " edge" " contraction c is made near each bulb to form an " indestructible index " from each column of mercury, a column of air being interposed between them. After a temperature has been taken by means of one bulb, the other bulb may be used, and the column oi mercury rising from it drives back the index previonsly obtained from the other column and forms its own " indestructable " index." In the modified form shown in Fig. 2, the tube is provided with only one contraction c, a column of air being interposed between the two bulbs. In this case the column of mercury rising from the bulb, near which is the contraction c, will form an index which is read by the scale of that bulb. The other bulb may then be used, and the column rising from it will push back the index of the first bulb, and on cooling will return to its bulb. The temperature will then be read from the outer end of the " indestructible index " by means of the scale of the second bulb. Instead of employing an " indestructible, index," the tube may be provided with a Phillip's index, consisting of a small body of mercury d, Fig. 3. In that case, the bore is reduced near each bulb as shown at e, to prevent the index from following the retreating column into the bulb. The temperature is read from either end of the index by the scale belonging to the bulb last used.
Patent GB-190420309-A (GB)
Title: Improvements in and relating to Measuring, Delivering, and Registering Taps for Liquids.
Inventor: ROBINSON CHARLES
Filed: 1904-09-21
Granted: 1905-07-20
Abstract: 20,309. Robinson, C. Sept. 21. Measured quantities, delivering.- A measuring- vessel for liquids is filled and emptied by actuation of a lever, the movements of which are counted electrically. The vessel 1, F i g. 4, depends from a duct 2, which may be adapted to be fitted into the side of the supply cask &c., and may have a pillar 5 to strengthen it ; or the liquid may be conveyed to the duct by a pipe 3. A cock 6 at the upper end of the vessel, having a two-way or angled passage, and a cock 7 at the lower end 1 are connected by levers and a connecting-rod (not shown), one lever, preferably the lower, having a handle attached to it. The lower cock is closed, when the handle is raised, before the upper is opened. At the same time that the upper cock cuts off the supply of liquid, it may open an air inlet so as to allow the liquid to issue freely through the lower cock. Preferably, however, an air valve of the self -closing float type is provided. A small passage 16 communicates with a chamber 11 containing the float 10, guided by a spindle 12 and carrying a rubber valve face 14. A grating 17 is provided to break the force of the entering liquid, and a pipe may be fitted, if necessary, to carry away any froth. A short tube 32 is screwed into the passage 16. Alternatively, the measuring-vessel 1 may communicate by means of a pipe, preferably having a self-closing valve, with the upper part of the storage vessel. The lower lever 19 extends into a case 18, Figs. 4 and 7, and, when the handle is raised, strikes a spring dog 20 on an arm 21 just before the liquid is admitted into the vessel. A contact 22 on the arm is thus thrown against a contact-spring 23, and an electric circuit completed through an electromagnet (not shown), the armature of which (by means of a pawl) advances a ratchet-wheel by one tooth to actuate the counting-mechanism. In its return movement, the lever 19 passes over the catch 20 without moving the arm 21. If preferred, the apparatus may be arranged so that the measuring-vessel is filled when the lever is lowered and emptied when it is raised. The registering-device has two hands, which can be set to zero, moving over concentric dials, and may also be provided with an independent hand adjustable from outside. Ducts from two or more store vessels may be led to one delivery tap, the duct 2 being, if necessary, of oval or other shape. One or more delivering taps, for instance for different liquors sold at the same price, may be connected to the same registering-appliance, or one registering - appliance may have several wheels acted on by different magnets.

Title: Improvements in and relating to Valve Mechanism for Prepayment Gas Meters and the like
Inventor: REEVES EDWIN ARTHUR
Filed: 1904-12-19
Granted: 1905-02-02
Abstract: 27,670. Reeves, E. A. Dec. 19. Hinged valves; lift valves.-Relates to valve mechanism for prepayment gas meters. After insertion of a coin which by forcing back an arm turns a shaft 10, Fig. 3, the latter and a lever 23 are gradually returned by the incoming gas passing through the meter so that a valve disc 14 is brought on its seat on a collar 29, the main supply of gas being cut off. A diminished supply flows through a port hole 19, Fig. 4, in a threaded plug 15 and thence through the space between a plug 26 and a port hole 17 in a cap 16 which is screwed on the plug 15. Warning is thus given that the supply is about to fail. The lever 23 ultimately causes an auxiliary valve 24, secured to the stem by means of a pintle 25, to close the porthole 17 against the pressure of springs 28, thus entirely cutting off the supply of gas. To vary the length of time of supply of gas at the diminished pressure, a nut 30, slotted at one edge to engage a pin 20 driven in the plug 15 and cut away to uncover the port 19, is moved longitudinally up or down by rotating the valve disc 14 ; the distance between the valve 24 and port 17 at the time of cut off of the main supply is thus varied. A baffle-plate 8 is arranged to prevent tampering with the valve mechanism.
