Title: Improvements in Oscillating Steam and Air Engines.
Inventor: DAWE CHARLES
Filed: 1905-02-13
Granted: 1905-10-26
Abstract: 2889. Dawe, C. Feb. 13. Oscillating e n g i n e s ; valves and valve-gear.- Steam is admitted in an oscillating engine by a piston valve contained within an oscillating sleeve or seat which acts as the exhaust valve. This sleeve is actuated by tappets carried by a reversing frame supported by the trunnions. The admission valve E is secured to the valve spindle K by a screw, and takes steam at the centre, is provided with helical edges, and may be revolved by the toothed gearing M to vary t h e expansion. There are separate admission and exhaust ports. The latter enter the cylinder at some distance from the ends. If desired, single ports may be used. These ports are parallel to the edges of the slide valve. If single ports are used, the sleeve C is modified to suit this arrangement. The means for actuating the sleeve is shown in Fig. 8. The spindle F, Fig. 1, is provided with lugs engaging ,the sleeve C and a shoulder bearing against the valve-chest cover D. Attached to the top of the spindle F are plates G which engage with bars TV, UW, Fig. 9, in such a way as to rotate the sleeve. For reversing, the frame J is moved over until the plates engage the bars wv, ut. The frame is inoperative in the central position. In a non-reversible engine, one set of fixed bars is used. To the plate are attached pins x which may operate the boiler-feed and liquid-fuel pumps y. The eccentric rod moves a pin L formed in one with a guide-block sliding in a groove in the cylinder. There is lost motion between the pin L and rod H. The toothed gearing M may be actuated by a flexible shaft upon which a pulley may be placed and wires wound thereon to actuate the suction valves of the boiler feed and liquid-fuel pumps. One part of the admission valve is made to cover the ports completely, and is provided with a shallow narrow groove b. The steam and exhaust passages may pass through flexible pipes instead of the trunnions. When the valve-edges are made flat, the valve-rod is keyed to the boss of the pin L. A modification of the ports is described suitable for a single-acting engine. According to the Provisional Specification, a single disk provided with pins may be used instead of plates G, and the pins X may also work the lubricating-oil pumps, the air-pumps for the condenser, and air-supply pumps for the furnace. Instead of lost motion taking place between the washer and toothed wheel as described, it may take place between the valve and valve-spindle. Instead of a toothed wheel to turn the slide-valve spindle, a lever and notched plate may be used. The cut-off edges of the slide valve may be stepped or the valve made with detachable rings.

Title: Improvements in Instruments for Surveying Bore-holes.
Inventor: LEWIS PERCY EDWARD
Filed: 1905-06-13
Granted: 1906-03-08
Abstract: 12,271. Lewis, P. E. June 13. Clinometers; compasses, magnetic.-Relates to instruments for surveying bore-holes, in which the magnetic needle and plummets s are fixed in position by admitting air or gas under pressure into or exhausting air or gas from an enclosing casing. The plummets 16, 17 are shown mounted in a casing 15 placed inside a casing 9 in which the compass bowl 12 is suspended. The casing 9 is weighted at 11, and its end caps 9<a> carry pivots 10 engaging bearings in plugs 4 screwed into the ends of the casing 3. The plugs 4 carry end elastic pads 8 and peripheral packing-rings 6 to steady the instrument in the outer casing 1. Fig. 10 shows a number of these instruments arranged above one another in an outer casing 1 closed at the ends by screwed plugs. Air or gas under pressure may be stored in the upper part of the casing 1 and admitted to the casings 3 by opening an electrically-operated valve 22<b> at the end of an inlet tube 22<c>. Fig. 4 shows means for fixing the magnetic needle 14. The gas under pressure passes through a passage 26 and perforations covered by an elastic non-return valve 30. A rubber diaphragm 37, arranged as shown, is then pressed against a plate 44 so as to raise the needle 14 against a rubber ring 48. To enable the compressed gas to escape, when it is desired to re-set the instrument, a screw plug 50 is removed. In a modification, the needle is pressed down against the action of a spring by a diaphragm at the top, and spring catches are used to bold the needle against 4 rubber ring. In another modification, the compressed gas acts on a piston which pushes catches aside so as to release a spring - raised clamp. As shown in Fig. 1, 2, and 3, the plummets are clamped against rubber strips 94<a> by spring clamps 92 released by the operation of catches 54<a> connected to pistons 88 exposed to the pressure in the casing 3. The plummets are observed through the transparent sides 87 of the casing 15. Baffleplates 97 may be arranged at the inlets to the casing 3. In a modification, the compass is arranged to act also as a plummet. It is arranged in a closed pivoted casing and carries a vertical ring with a milled periphery adapted to be engaged by a spring clamp freed by a catch operated by a piston exposed to the pressure in the casing 3. The piston, in moving, opens passages to admit compressed air to clamp the compass needle. In a modification, the casing containing the compass is not pivoted, but the compass bowl is mounted in gimbals inside the casing, which is adapted to slide into the casing 3. The compass bowl is clamped in position by a spring clamp, carried by the outer gimbal ring and freed by a catch operated by a piston. This piston is acted on by a screw-adjusted spring. The casing of the instrument may be partly filled with water, oil, or other liquid.

Title: Improvements in and connected with Weft Feelers for Automatic Weft Replenishing Looms.
Inventor: STITT WILLIAM RICHARD
Filed: 1905-10-17
Granted: 1906-10-11
Abstract: 21,013. Stitt, W. R. Oct. 17. Loom weft - replenishing mechanism ; shuttles.- Relates to means whereby weft - replenishing mechanism may be actuated when the weft is substantially exhausted. A hollow tube B is secured within a weft bobbin or the like, and is provided with a sliding rod D, which is normally held within the tube and bobbin, against the action of a helical spring d, by a spring catch C engaging a collar d<2> or the like at its inner end. The bobbin has a slot a, within which the catch C is held in engagement with the collar d<2> by the weft on the bobbin ; but when the weft over it is removed, the catch C springs outwards and releases the rod D, which is thereupon caused to project outwards from the end of the bobbin by the action of the spring d. The projecting end of the rod D may return the motion of any suitable pusher and cause the weft-replenishing mechanism to be operated. Similar mechanism is described as applied to a weft case having a cop spindle, and in this case the catch is centrally pivoted, and is held with its catch end engaging a collar on the sliding rod by the action of the cop end on the other end of the catch.

Patent GB-190525287-A (GB)
Title: Method of and Apparatus for Striking Electric Arcs between Electrodes.
Inventor: PETERSSON ALBERT JOHAN
Filed: 1905-12-05
Granted: 1906-07-26
Abstract: 25,287. Petersson, A. J. Dec. 5. Electric furnaces; arc lamps.-In furnaces for treating gases, in arc lamps, or elsewhere, electric arcs are started between subsidiary pairs of electrodes, which are connected so as to take but little energy, and transferred to the main electrodes. Variation in the resistance of the main arcs is thus diminished. In one form of furnace, of which Fig. 1 is a vertical section, each of the subsidiary electrodes 1, 2 and main electrodes 3, 4, 5, 6 is connected to alternating-current mains through the primary of a transformer 7, 8, 9, 10, 11, 12, and is also in the circuit of the secondary of the transformer. An arc formed between the electrodes 1, 2 moves upwards until it meets the lower ends of the electrodes 3, 4, which ends are flattened or enlarged for this purpose. The arcs between the electrodes 1, 3 and 2, 4 continue until the resistance of the arc between the electrodes 3, 4 becomes so great that another arc is formed directly between the electrodes 1, 2. The arc between the electrodes 3, 4 is similarly transferred to the electrodes 5, 6. The movements of the arcs may be produced by means of an electromagnet E, Fig. o, having pole-pieces extending vertically on each side of the furnace. Both the electro-magnet and the arcs are supplied with direct currents, or with alternating currents of the same period ; if, however, the main electrodes 26, 27, &c., Fig. 10, are placed both above and below the subsidiary electrodes 18, 19, direct current may be used for the electro-magnet and alternating current for the arcs. The currents supplied to the different electrodes may in this case be of different phases. Inductances F are placed in circuit with the electrodes. In another modification, there is a central vertical electrode, around which are other electrodes forming an interrupted helix ; a curved arm projects from the central electrodes to within arcing distance of the lowest helical electrode, and the lower end of each of the other helical electrodes extends between the upper end of the next one below it and the central electrode.
