Abstract: 9629. Thompson, W. P., [Brooks, A. J.]. April 25. Stoppers ; refilling, preventing. -The neck of the bottle is formed with an internal shoulder 2, its mouth 11 being preferably made concave to receive the correspondingly-shaped base of the head 7 on the tubular stopper 5. The stopper is provided with a packing- washer 10, and with one or more resilient arms 6, which, when the stopper is inserted, spring under the shoulder 2 and lock the stopper in position. The head 7 is formed with two or more ducts 8, which communicate with the central passage 9 of the stopper, external notches 12 being also formed in the stopper in alignment with the ducts 8, to direct the outflow of the liquid. The ducts serve for the discharge of the liquid from the bottle and for the inlet of air, but their arrangement prevents the introduction of liquid through them. To prevent the liquid from being discharged by accident, a screw-cap stopper 13 is screwed down on a threaded portion of the head 7, so that it seats on the washer 16. When the arms 6 are made integral with the stopper 5, the washer 10 may be made in two longitudinal sections, but when the arms are made separate, the washer may be in one piece, and placed on the stopper before the arms are fixed thereto.

Granted: 1903-09-03
Abstract: 21,807. Westinghouse, G., [Knox, W. J.]. Oct. 7. Drawings to Specification. Firebricks ; building-blocks. - Relates to the manufacture of a material for making bricks or blocks for the linings of furnaces, converters, and other vessels used in metallurgical operations, particularly for treating mattes and refining metals. A suitable basic material, such as magnesite, chromium oxide, or other refractory basic oxide, which is not hydrated by the addition of water, is mixed in the powdered state with iron oxysulphide obtained by adding an iron oxide to a molten iron sulphide, and a small percentage of waterglass is added. The mixture is then rendered slightly plastic by adding water, and is applied to the walls of the vessels, preferably by packing it by means of a pneumatic rammer between the walls of the vessels and temporary inner walls. After evaporating the excess of moisture, the inner surface of the linings is saturated with calcium chloride solution, preferably by spraying. The iron oxysulphide may be dispensed with, or the calcium chloride may be added before the water- glass. The iron oxysulphide may be obtained by oxidizing molten copper matte containing iron and copper sulphides in a basic-lined vessel by means of an air blast.

Title: Improvements in Steam Traps.
Inventor: DUNHAM CLAYTON AUBRA
Filed: 1903-08-17
Granted: 1903-12-10
Abstract: 17,790. Dunham, C. A. Aug. 17. Lift valves; actuating valves and cocks ; dirt, preventing lodgment of.-Relates to a steam trap in which the contraction or expansion of a diaphragm chamber, containing a fluid sensitive to changes of temperature, opens or closes the discharge valve. One form, for low pressure or vacuum work, has a valve port 13, which is closed by a thermostatically-controlled valve 14, and a bye-pass port 18, which is closed bya screw-down valve 19. Both ports are formed in a "bridge" 8, between the inlet 6 and outlet 7, which latter are coaxial. The valve 14 has a short stem 16, which is made to fit the socket of a tool, adapted to rotate the valve for the purpose of grinding it to its seat without removing the trap from the pipes. The thermostatic device consists of a diaphragm chamber 36, preferably formed by sweating the edges of two plates together, lapping and soldering them with silver solder. It is filled with some liquid sensitive to changes of temperature, such as ammonia, and held peripherally between the casing and its cover. A filling-nozzle 42, provided with a screw-plug, has a shoulder 44 secured to one plate of the diaphragm chamber, and terminates near the other plate so as to prevent the chamber from collapsing. A pin 54 in a cup on the shoulder 14 forms a detachable coupling between the diaphragm and the valve 14. In a modification for high. pressure work, Fig. 3, the thermoftaticallycontrolled valve is provided with heads of different area 68, 69, mounted on a stem passing through the guide-lug 64 of a bridge which extends across the inlet 58. The stem has an extension 70 which moves in a socket 71 in the removable head 72. The other end of the stem forms a spindle 73 having a socket 74 to receive the nozzle of the diaphragm. A deflector 75 across the outlet directs the steam or water against the diaphragm. To the inlet 6, Fig. 1, is coupled the filter 46, provided with a plug 51, which may be removed for cleaning purposes. A strainer 52 of wire fabric or metallic copper is placed across the opening of the filter casing.

Patent GB-190409748-A (GB)
Title: Improvements in Looms for Weaving Pile Fabric
Inventor: HARTLEY WILLIAM GREENWOOD
Filed: 1904-04-28
Granted: 1904-07-07
Abstract: 9748. Hartley, W. G. April 28. Looms, pile forming and cutting in.-In looms for weaving pile fabrics in which the pile loops are formed by crossing the pile threads 5 over longitudinal wires 10, the pile wires are arranged with their back ends 14 free, so that the pile threads may be passed completely round the wires, and single loops of the desired colours may be formed. When a cut-pile fabric is to be woven, the front ends of the wires 10 are supported by a locking-bar 13 which, together with the loops drawn tightly over the forming portion of the wire, holds the free ends 14 in position without further support. The front end of each wire is made in the form of a shoe 11 to hold the cutting-knife 12. When Brussels carpet or other looped-pile fabric is to be woven, the front end is prevented from being carried forward at the beatup by a cross-bar which is raised by a cam to allow the loops to pass off when the fabric is drawn forwards by the take-up mechanism. The ends 14 are supported by upright iron bars which are magnetized by means of electromagnetic coils. By the use of a rotating disc carrying two insulating-blocks, the electric circuit is broken and the bars de-magnetized when the pile threads are passing the ends 14. Weak permanent magnets may be used. In another arrangement, Fig. 7, the ends 14 have eyes 14<a> into which rounded points 35 on upright wires 34 project. The pile threads may be readily drawn up or down past the points. Each end 14 may be supported by one wire 34 instead of by two. The ground warps from the beam 1 are shed by heald shafts 3, the stuffer warps from the beam 2 by the heald shaft 4, and the pile warps 5 from bobbins 6<a> by jacquard harness, or for plain carpeting by heald shafts operated by cams, or by a dobby. The raised pile threads 6 are carried laterally over the pile wires 10, and back again underneath the same to form the loops by means of cranked wires 9 pivoted in fixed bars at 16, 17. Screws 20 secured in the upper fixed bar pass through slots in a sliding bar 19, which is moved along the fixed bar by a cord operated by a jacquard hook, or by the dobby, or by a cam, and returned by a spring. Pins 18 on the sliding bar engage the crank portions 8 of the wires 9, so that the cranked wires are partially turned when required to carry the pile threads over or under the wires 10. The ends 14 have rounded protuberances which prevent the pile threads from slipping back on the wrong sides of the wires. The pile threads are carried over the wires 10 when the reed 26 is in the backward position, so that it serves as a guide for the threads, confining them within the space in which they are desired to work.

Title: Improvements in Apparatus for Cleansing Filter Beds.
Inventor: BLAISDELL HIRAM WHEELER
Filed: 1904-06-28
Granted: 1904-08-25
Abstract: 14,536. Blaisdell, H. W. June 28. Filters, cleansing. - An apparatus for cleansing filter beds, formed of sand or other material, by removing a layer of the material from the surface, is shown in end elevation in Fig. 1 and partially in side elevation in Fig. 3. The apparatus moves along the filter bed upon rails 17 placed at either side, the motion being communicated from an electromotor 21 to the bearing- wheels 16 by a belt 22, spur-wheels 25, 35, or 26, 36 if greater speed is required, bevel gearing 38, a worm 41, and a worm-wheel 42. A layer of sand is removed from the bed by a rotating scraper, formed by right and left handed helical blades 47, 51, and collected between them into buckets 55 on an elevator belt 54, which passes over a pulley on the scraper shaft and causes the shaft to rotate. At the top, the belt passes over a pulley 56 driven from the shaft of an electromotor 65, Fig. 3, by spur-wheels 58, 59 and a belt 62. The sand from the buckets is discharged down a shoot 66, Fig. 1, on to a conveyer belt 67 passing around a pulley 68, which is driven by a belt from an electromotor 74. The conveyer-belt, which is guided by pulleys 78 to take a V- shape in cross-section, discharges the sand at the side of the apparatus. The scraper is supported in a frame 50, balanced over a pulley 85, Fig. 3, on a second frame 82 by a weight 89, and the height of the scraper is varied for unevenness of the bed by a gauge shoe 110, pivoted about bearings in the frame 50. To regulate the depth of work, the position of the gauge shoe relatively to the scraper is altered by means of a screw-threaded adjustment rod 118, to which the bearings of the gauge shoe are attached. The scraper frame 50 can be raised out of the bed by means of an electromotor 106, Fig. 1, which rotates screws 90 by means of a belt 103 and bevel gearing 100. The screws engage with screwthreaded blocks 91, Fig. 3, attached to the frame 82, and lift it relatively to the main frame 15 by their rotation. Projections 134 catch up the frame 50. The action of the scraper is assisted by fixed blades 130 ploughing furrows at either side. In one modification the elevator belt 54 is passed over a pulley on an axis behind the scraper, which drives the scraper by spur gearing ; in another, the frame 50 is fixed in the frame 82, the weight 89 is replaced by a weight which balances the combined frames, and slight vertical motion for unevenness of the bed is allowed by passing the pivots 92 of the blocks 91 through slots formed in ears projecting upwards on the frame 82.
