Screw pumps.-Relates to propellers, suitable for submarine vessels, air ships, and torpedoes, of the type described in Specification No. 1140, A.D. 1905, [Abridgment Class Ammunition]. The propeller is mounted in the bows of a boat, preferably of an elongated ovoid shape provided with bilge keels d, e, the upper ones being curved slightly downwards and having at the stern independent horizontal rudders turning on horizontal axes on either side of the main rudder. The propeller has a conical cavity which fits over the conical bows of the vessel and preferably has six blades. The part of the surface B included between the point m on one blade, the corresponding point m on the next, and a point n in a line drawn at right-angles to the last-mentioned point m is cylindrical, the line m, n making an angle of about forty-five degrees with the base. The rest of the surface B is spiral, varying in gradient from n to h. The inner surface C is an irregular surface which slopes away from the edge m, n, o, h to meet the surface B of the next blade, the angle between the surfaces B, C being not greater than forty-five degrees. To assist the propeller in engaging the fluid, blades D are set along the edges m, n normal to the cylindrical part of the surface B. To protect the vessel against the action of the wave thrown up by the propeller, an openended drum may be mounted at a suitable distance from it, allowing the water displaced by the centrifugal action of the propeller to pass away at the rear. This drum may be used as a support for a search-light.

Title: Improvements in Electrolytic Diaphragms.
Inventor: ROBERTS ISAIAH LEWIS
Filed: 1906-06-30
Granted: 1907-06-29
Abstract: 14,922. Roberts, I. L. June 30. Diaphragms.-A diaphragm for electrolytic cells is made up of a rigid body of porous material, a layer of plastic non-porous material, and a fabric enclosing this layer, with or without a framework of, say, wiregauze to support the fabric. In the form shown in Fig. 1, a wire basket 1 is stiffened top and bottom by metal rings 2, 3, and has a cloth lining 4. A layer of plastic material 6 is placed on the bottom of the basket and a disk 7 of rigid porous material, preferably a composition of asbestos and magnesium silicate, is pressed down on the layer 6. A tube 8 of the same composition is then placed on the disk and the space between this tube and the cloth lining is evenly packed with the plastic material. In a modification in which the diaphragm is in the form of a flat plate extending longitudinally through a trough, the wire support is omitted. The plastic material is preferably prepared by finely grinding anthracite coal or other badly-conducting body which is not attacked by the electrolyte or decomposition products; this body should contain a certain percentage of silica. The powder is made into a stiff paste with a solution of sodium or potassium silicate and caustic soda or potash ; after the diaphragm has been made up, it is immersed in a saturated solution of common salt, which gelatinizes the silica in the powder used and binds up the whole. [Reference has been directed under Patents Act, 1902, to Specification No. 13,358, A.D. 1894.]

Granted: 1907-08-22
Abstract: 24,089. Reeves, W. Oct. 29. Fixed - abatment t y p e having pistons with outwardly - sliding vanes. Relates to valve-gear for reversible rotary engines of the type shown in Figs. 1 and 2, in which a drum b carrying a piston vane c rotates concentrically in an annular casing a. This casing is circular in section except at the ports g, h, Fig. 1, where the walls curve inwardly to form an abutment. Between the ports g, h, a packing-strip k is fitted, and packing-rings G are expanded between the drum b and casing a by spring steel rings F. The piston c is guided in a radial slot in the drum, and is pressed outwardly by spring d. It carries spring-pressed packing- strips e, e', and packing is also fitted where it passes through the slot. Slide valves o, p, preferably of the grid type control the similar ports g, h, and a distributing-valve n controls communication between the valve-chests and the inlet pipe land exhaust pipe m, respectively. The gear is such that the valve o is intermittently opened for admission and the valve p is permanently opened for exhaust, or vice versa, depending on the direction of rotation. The rods s, t connected with the valve-rods are rocked by tappets engaging pairs of cams on the engine shaft H. The outer cams u, v, Fig. 3, open the valves. The closing-cams x, y are arranged so that when one is operative the other is inoperative by fixing them, as shown, to a rotating sleeve w splined to the boss of the cam u. On reversing the engine, the lever E which moves the distributing-valve n also shifts the sleeve wand cams x, y longitudinally, by means of a fork A on the rod D engaging a strap z on the cams. The cams x, y are clamped by set screws to the sleeve w in an angular position depending on the cut-off required. The angular position may be varied automatically while running by a governor. Fig. 4 shows a device for this purpose. The forms of the slots used for converting the sliding motion of the governor rod T into rotary motion of the cams P, Q are shown in Fig. 5. The cams on the sleeve I are connected with rotatable collars K, L by screwed pins M. The slots N, 0 for the pins are so shaped that the sleeve I may be shifted longitudinally by the strap J, and also the collars K, L and the cams P, Q may be shifted angularly and simultaneously without being stopped by the sleeve. The position of the block T in the hollow end of the engine shaft H depends on the position of the governor weights. The collars K, L are shifted angularly by pins U on the block which carry rollers V, working in inclined slots X, Y in the collars and in straight slots Z in the shaft. According to the Provisional Specification, the engine may be modified to take fresh steam two or more times per revolution.
