Granted: 1903-05-21
Abstract: 2488. Haddan, H. J., [S³ddeutsche Prõcisionswerkzeugfabrik Bartholomaeus & Co.]. Feb. 2. Stocks and dies.-Sections of threads of different gauges are formed on the ends of arms d of different lengths. The arms are arranged in sets, as shown, which radiate from pivots f taking into radial slots g in the plates b and into inclined slots k in plates h. The plates h are connected together by a handle l, by which they may be rotated on the plates b so as to force the dies slightly towards or away from the centre of the stock. The plates b are fixed together by pins c, and screw into the stock with right and left hand threads. The arms d are fixed during use by means of the slotted sleeve n, which is pushed down over them, and by the plates b which, when turned by a key, move together and clamp the arm, d. The cuttings escape through openings p.

Patent GB-190401632-A (GB)
Title: Improvements in and connected with Machinery or Appliances for Rolling Metal into Strips.
Inventor: HALL JOHN WILLIM
Filed: 1904-01-22
Granted: 1904-12-22
Abstract: 1632. Hall, J. W., and Scarf, F. Jan. 22. Rolling.-In a machine for rolling metal strips, the movable scraper-bars 8, 9 are lowered by mechanical means as soon as the end of the strip 5 is seized by the rolls 1, 2, so that the bar is bent, as shown in Fig. 7, and the scale easily removed. The stationary scrapers 6, 7 are fixed by suitable means to the framing of the machine, and the movable scrapers may be held on a crosshead 10 attached to the rod of an air-cushioned spring-actuated piston 14, Fig. 4, a detent 13, actuated by a hand-lever 38, holding up the piston until the strip enters the rolls. The piston is raised again by a handoperated lever turning a pinion 24 on the shaft 25, a rack on the piston-rod gearing with the pinion, and the tension in the spring 16 which actuates the piston is adjusted by turning the spider wheel 18. In a modified form of the machine, the piston is raised by means of a compressed-air cylinder, and the detent 13 released by means of a lever which is turned over by the strip of metal as it passes through the rolls. In another form, Fig. 19, the piston is both raised and lowered by compressed air, the shock at the end of the stroke being prevented by a barrel - shaped cataract cylinder 75. In this form there is an additional fixed scraper-bar 90, the movable scrapers 8, 9 being connected with the piston-rod 11 by a series of lever links 81, 85, 87, &c. The release of the detent 13 and the control of the valve for the raising of the piston may be actuated electrically as in the arrangement shown in Fig. 22. The metal strip on passing through the rolls is made to close the circuit containing the solenoids 91, 112. The former causes the lever 99 to rise and so release the detent 13. The latter controls a valve 111 regulating the piston 105 for admitting air to raise the piston 14 and keeps the valve closed until the strip has gone right through the rolls and the contact is again broken. The lowering of the scraper-rods might also be accomplished by means of a falling weight connected with them by a lever.

Title: Improvements in Wattmeters
Inventor: DUDDELL WILLIAM DU BOIS
Filed: 1904-02-06
Granted: 1904-12-15
Abstract: 2948. Duddell, W. du B. Feb. 6. Energy meters.-A watt-meter has a coil, Fig. 1, which can turn in a permanent magnetic field and carries two thermocouples t1, t2, the outer junctions of which may be heated by two adjacent stationary resistances h1, h2. The thermocouples t1, t2 may be connected to two independent windings, as shown in Fig. 1, or they may be connected in series to a single winding, but in either case they act oppositely to each other. The stationary resistances h1, h2 carry currents respectively the sum and difference of two currents which are proportional to the main current and pressure to be measured ; the heating of the resistances h1, h2 is proportional to the squares of the currents carried by them, and under these conditions the instrument indicates the power supplied. Various arrangements may be used to obtain the sum and difference currents. In that shown in Fig. 7, the two heating resistances h1, h2 are connected in series with a non-inductive resistance R between the supply mains M1, M2, and are also connected to two secondary windings of a transformer T2, the primary winding of which carries the main current. Fig. 9 shows pressure and main current transformers T1, T, having their secondary windings connected to the junctions of a quadrilateral arrangement of the two heating- resistances h1, h2 and two non-inductive resistances R1, R2. In another arrangement the two heating- resistances are connected in series to the ends of a single non-inductive low resistance, inserted in one supply main, and the junction between the two heating-resistances is connected through a non- inductive resistance to the other supply main, In order to measure the sum of the power supplied to two circuits, on a two-phase or three-phase system, two coils are connected together, to turn in a permanent magnetic field, and carry two pairs of thermocouples heated by four stationary resistances ; or all four thermocouples may be connected in series with a single movable coil. In the construction of the indicating-instrument, pivots may be placed within the movable coil, and the thermocouples outside it, as shown in Fig. 1. Or the pivots may be outside, and both thermo- couples carried by extensions below the lower pivot. The thermocouples may consist of iron and constantan, with small silver or copper plates to receive the heat from the heating-resistances, which may be made of platinum or other wire or foil.

Granted: 1905-06-08
Abstract: 13,205. Ford, J. M. June 11. Resistance at various speeds, determining.-Comprises means for testing shipe' models for resistance in experimental tanks. A weighted trolley i, fitted with a pointer k and adapted to roll on an inclined rail, is connected by the guided cord @ to the trolleys q, which run on a level rail and are connected together and to the model b by the cord r. As the trolley i runs down the long incline c, e, the model is drawn from the point B towards the point C and the arrangement is such that, after a certain period from the commencement of the motion, the model and trolley travel at a uniform velocity until the bottom of the incline is reached. The trolley then runs up the incline e, t and comes to rest. In a modification, suitable for large tanks, the cord s is dispensed with and the trolley i is connected to the trolleys q. The method described maybe used for an air ship by connecting its model to the trolleys q.

Abstract: 27,945. Abbey, N. W. Dec. 21. Stuffing - boxes. - Hy draulic cylinders are provided with stuffing-boxes containing two or more cup or other leathers. Fig. 1 shows an old cylinder with a stuffing- box secured to it, but new cylinders may have the box cast on. The box is made with a projection B' fitting the usual recess, a tight joint with the cylinder being made by washers B', D. In the base of the box is placed a cup-leather F<1>, and over this a metal ring G, a tight joint with the shoulder F<2> being made by a washer W. Similar leathers and rings fill the box, which is closed by a screwed gland K, the inner end of which is similar to the rings G. The upper face of the gland is dished to receive oil to lubricate the ram, which is supported by a ball bearing L. This bearing is lubricated by oil passing through the opening in the gland. The ball race may be formed partly in a ring placed above the upper ring G and partly in the lower end of the gland. Hatleathers may be used instead of, or alternately with, cup-leathers. When the ram is of large diameter, the rings and washers may be dispensed with, and a long sleeve used with recesses for the leathers. This sleeve may be formed in one piece with the gland.
