Title: Manufacture of Bluish Black Sulphurised Dyestuffs.
Inventor: IMRAY OLIVER
Filed: 1902-11-24
Granted: 1903-09-24
Abstract: 25,851. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Nov. 24. Dyes, artificial.-A blue-black sulphurized dyestuff is obtained by heating with alkali polysulphide, at temperatures of 130‹-160‹ U., the product obtained by passing air into an alkaline solution of equi-molecular proportions of a dialkyl. p phenylenediamine and phenol, a copper conpound being also present in the solution. For example, dimethylaniline is converted into nitrosodimethylaniline, which is afterwards reduced to dimethyl-p-phenylenediamine, both by known methods. The solution of this body is treated with concentrated caustic-soda lye, and filtered, phenol, and copper chloride in ammonia of 20 per cent. strength, are added, and then air is passed in. The product is separated by filtration, passed into a sodium-sulphide solution containing sulphur, and heated to about 130‹-140‹ C. during stirring for about 30 hours. The dye-stuff is precipitated with dilute acids. Diethyl-p-phenylenediamine yields a similar product.

Title: Improvements in Inferential Water Meters.
Inventor: THOMSON JOHN
Filed: 1903-12-30
Granted: 1904-11-03
Abstract: 28,677. Thomson, J. Dec. 30. Impulse and reaction meters.-A meter of the type in which the volume of water flowing through is calculated from its velocity, is formed by arranging two vane wheels on the same spindle, the axis of which is at right-angles to the line of flow of the water. Fig. 1 shows a sectional view of the meter. The cylinder 5 encasing the vane wheels is mounted in a bearing 6 and is provided with perforated endplates 12, 13. The spindle 18 carrying the vane wheels is supported on a roller-bearing 22, and revolves in the lined hubs 15, 16 attached to the end-plates. The discs 19, 20 carrying the blades or vanes are made hollow, the water-tight compartments 26 being so proportioned that the structure will nearly float. The ports 24 in the cylinder 5 prevent foreign matter from passing to the vane wheels. The water, after entering the passage A, divides into two branches, as shown by the arrows, passes the vane wheels, and re-unites in the chamber P. The cylinder is provided with ports 25 to allow the water to flow away from this chamber. To reduce the resistance to the passage of water, the edges of the inlet rings in the discs may be rounded or tapered as shown at 30 in Fig. 4. The register E and its internal gear are mounted in the cap 27, the primary pinion of the gear being driven from the discs by means of the arm 28 which engages the slot 29 in the upper end of the spindle 18. The direction of the flow of the fluid may be reversed.

Title: Improvements in or connected with Automatic or Self-threading Shuttles.
Inventor: CHADWICK HERBERT
Filed: 1904-07-18
Granted: 1905-03-30
Abstract: 15,897. Chadwick, H., and Gerrard, W. July 18. Loom shuttles.-Relates to automatic self-filling shuttles for Northrop looms, and also to other shuttles. In a recess a, Fig. 1, in the shuttle A opposite the nose of the bobbin or filling carrier B, and in the same axial line, is placed a coiled or spirally-formed thin metal strip h, secured to the base of the recess or to a removable plate or block c therein ; or a wire spiral or spring k, Fig. 6, or other similar device is provided. When a full filling carrier, or a full shuttle, is inserted in the loom, the free end of the filling-thread being secured to a fixed projection on the loom or filling- carrier magazine in the usual manner, at the first pick across the loom, the filling winds off the carrier B with a circular motion, engages against the outer convolution of the spiral device b, and is guided into the central volute, or, in the modification, Fig. 6, the thread enters one of the convolutions of the spiral k and then by a screw-like action winds itself through several convolutions, finally travelling through the central axis of the spiral spring. At the return pick, the thread, which has entered a thread passage e in a block or plate d integral with or separate from the plate c and has passed under the horn f, is caused to pass through an undercut passage g to a guide-eye h, or, in a modification, direct from the horn f to the eye by way of an ordinary saw-gate cut in the body of the shuttle, the latter being then completely threaded. In some cases, the devices b, k are incompletely threaded, the filling being then delivered direct therefrom. In hand-threaded shuttles, a second spiral may be secured at one side of the shuttle, about midway of the bobbin filling and extending to a point adjacent to the front end of the device b or k, to hold or retain control of the filling to the maximum extent to reduce ballooning. This may also be reduced by lengthening the device b or k and bringing the inner end thereof near the nose of the filling-carrier. The drag may be increased, as usual, by applying felt in the path of the filling.

Title: Improvements in Electrical Winding Mechanism and Switches connected therewith.
Inventor: DUBOIS EDWARD
Filed: 1904-07-21
Granted: 1905-07-21
Abstract: 16,210. Du Bois, E. July 21. Winding mechanism and apparatus; overwinding, preventing. - In electrically - wound clockwork mechanism for time switches and other purposes, consisting essentially of an intermittently-energized electromagnet the armature of which winds up the mainspring through a ratchet and pawl, means are provided for preventing stoppage of the clock when the current is accidentally cut off. In order to avoid overwinding, the mainspring is either allowed to slip when fully wound, or a second spring or a weight for operating a heavy switch &c. may be wound up by the further movement of the armature. The pivoted armature 2, Fig. 1, of the electromagnet 1 winds up the mainspring contained within the barrel 7 by means of a pawl 5 and ratchet-wheel 6. A current is sent at intervals through the electromagnet by the closing of contacts 12, 13, which is effected by a pawl 15 on a lever 10 provided with a pin 9 which bears upon a snail 8 driven by the clock mechanism. An adjustable projection 18<a>, Fig. 8, may be arranged on the radial edge of the snail to arrest the downward movement of the lever 10 and thus maintain the contacts closed for a short time. Three methods of preventing overwinding are described. (1) An auxiliary ratchet-wheel 19 is held by a spring- pressed click 20 which allows the ratchet-wheel to slip when the tension on the spring increases considerably. (2) The pawl 5 consists of two spring-controlled members a, b, Fig. 2, arranged in different planes. The member a drives the ratchet-wheel 6 until the mainspring is fully wound, when the pawl turns upon its pivot against the stop 25, allowing the member b to drive the ratchet-wheel 22 of a second mainspring. (3) The inner surface of the barrel 7, Fig. 4, is provided with notches 27 which engage with the end 29 of a strong blade-spring 28 having the mainspring attached thereto. The end 29 projects through a slot 30 in the cover-plate of the barrel, on which is loosely mounted a ratchetwheel 31 communicating through a pair of pinions with the second spring. When overwinding takes place, the end 29 slips from notch to notch and dnves the ratchet-wheel 31. A third spring may be wound in a similar manner.

Granted: 1904-10-06
Abstract: 17,309. D y m o n d, G. C., [Guy, A.]. Aug. 8. Carburetting. - The hydrocarbon - distributing apparatus comprises a cylindrical reservoir a mounted on a hollow shaft d and divided into two compartments by a partition b. The shaft d is divided by a partition g, and the two compartments communicate with the reservoir a through two holes e, f. At one end, the shaft d discharges into a box which supplies the evaporators 1, 2, 3, shown diagrammatically in Fig. 1. The hydrocarbon is introduced by the tap r into the bottom compartments of the reservoir when the partition is horizontal. The drum d is then rotated through the medium of toothed gearing by the shaft of the drum of the meter. The supply is thus proportional to the quantity of gas passing through the meter. The evaporations are preferably constituted by the ordinary gas meter paddle-drums revolving on the surface of water. The combustible liquid falls on the water, on which it spreads in a very fine sheet or coating. The drums of the evaporators have plates to increase their evaporation surface.
