Granted: 1903-07-30
Abstract: 14,565. Boss, M. P. June 30. Metallurgical furnaces.-Relates to metallurgical furnaces for the direct extraction of metals from their ores and the conversion of iron into steel within a single structure and without handling. The ore to be treated is first calcined in an inclined chamber 21 by the heat of the waste gases escaping to the chimney 31, and afterwards pushed by a mechanical rake 22 into a reducing chamber 23 heated by burners 58 using oil mixed with air or steam under pressure. The molten metal accumulates on a bed or hearth 24, fitted with a slag dam 26, and is conveyed by a trough 27 into a converter 29 placed in an oxidizing- chamber 30 also heated by liquidfuel burners. Silica and other impurities are removed by making the hearth 24 of a material which will 1 chemically combine with them; for example, where copper is treated, copper ore, matte, or iron ore may be used. Suitable fluxes and carbon may also be added to the metal through doors 46 in the side of the reducing-chamber. The converter 29 is supported on a carriage 33 running on rails 35, which are carried by a ring 36, having an inclined bottom and mounted on a similar ring 37 having an inclined top. Motion is imparted to these rings, to give a tilting movement to the converter for agitating the metal, by worms 39, 40 driven by power. Blast tuyÞres, supplied with air under pressure from a stationary pipe, are fixed in the bottom of the converter. Access is obtained to the trough 27 for cleaning &c. through doors between the walls of the chambers 23, 30, and blocks 28 are provided for stopping the flow of metal. In a modification, Figs. 9 and 10, the trough 27 is replaced by a passage 51 in the wall between the hearth 24 and chamber 30, and a slag ring 52 is provided instead of the drum 26, Fig. 1. The blast tuyeres 50 communicate with tubes 54 on a frame 53 detachably connected to the bottom of the converter and held in position by an arm 56 engaging a hook 57. A pipe 55 connects the frame with the source of compressed air.

Title: Improvements in Electrical Signalling Instruments.
Inventor: SULLIVAN HERBERT WATSON
Filed: 1904-03-21
Granted: 1905-03-16
Abstract: 6811. Sullivan, H. W. March 21. Telegraphs; relays. - In cable working, especially w i t h curb transmission or with "double block" duplex, when a siphon recorder is placed between the battery and cable so as to read the outgoing signals, the discharge from the cable after each impulse causes the siphon to record a trace which is difficult to read. To remedy this, the motion of the coil may be damped so that it does not return to the zero position until after the discharge from the cable or condenser has occurred, and the movement of the coil may automatically short-circuit itself entirely or in part. The coil a is wound on a closed metallic frame b, having flanges b<1> to damp the movements of the coil. Fig. 4 shows the arrangement for short-circuiting the coil. The contacts e, fare connected to one end of the coil, and, when the system is deflected, one or other contact comes against the contacts g, g', connected to the other end of the coil. The contacts g, g<1> may be mounted on springs g', having stops for varying the active length of the spring. The yielding springs may also be used simply to restrict the movement of the coil, without short-circuiting the same. The contacts may be faced with plush, camel hair, &c. so as not to jar the moving system, and may also serve to close a local circuit. The system may be further damped by varying the friction between the siphon and the moving tape. The Provisional Specification states that the apparatus is applicable to wireless telegraphy, and may be provided with a switch and adjustable resistance so as to serve as a " leak " recorder.

Granted: 1905-07-15
Abstract: 15,787. Boult, A. J., [Soc. GÚnÚrale de Bonneterie, and Boucher, C.]. July 15. Straight-bar knitting-machines.-Relates to detail improvements of the Cotton's type of rib top machine, comprising a simple frame needle motion, a durable form of sinker and sinker bed, a slur-bar adjusted by pattern means to control the length of the loops, a comb for preventing entanglement of new and old machine loops, a thread -guide changing-apparatus and a fabric take-up. The frame needles move vertically in the welt-loop knocking-over comb 490, except while forming the welt. To enable them to place the old welt loops on the comb 490, a special horizontal movement is imparted. Fig. 4 shows suitable jack sinkers with extension pieces 29, nibs 24, and cutaway under portions 23<a>. The latter permit the use of a thicker and more durable sinker bed 21, Fig. 3, without interfering with the pressing- operations. The sinkers are operated by a slurcock and a dividing-bar 75 and their movement is limited by the bar 52. The latter and the slur-bar are moved together towards or away from the needles by a lever 50, 51, a link 53, and an arm 54. Loops for ordinary, slack, or welt courses, tuck stitches, or sinuous ribbed work can be obtained by pattern mechanism rocking the arm 54, which is traversed in the ordinary way by a second arm and a cam on the shaft 3. In the alternative arrangement shown in Fig. 7, dividing-sinkers are dispensed with, the jack sinkers being in two sets operated by two slur-cocks. The machine needles 380, Fig. 3<a>, are prevented from crossing by the solid part of a comb 41, pressed down by springs, while undercut portions, by receiving the old loops, prevent the new loops adhering thereto. The thread-guides 113, Fig. 3, are mounted in groups on rocking carriers 130 by which any thread-guide may be placed between the frame needles and the sinkers. The take-up drum is driven by a ratchet-and-pawl arrangement.

Title: Improvements in Self-propelled Vehicles
Inventor: CAROLAN EDGAR ALFRED
Filed: 1904-08-16
Granted: 1905-06-22
Abstract: 17,810. Carolan, E. A., [General Electric Co.]. Aug. 16. Dynamos and motors combined for transmitting power ; motors, controlling. -Relates. to electric transmission of power from a suitable motor to the driving-wheels of a motor road vehicle, and comprises also a controller provided with a locking- device and operated by a special arrangement of foot-pedals. The arrangement of the parts on the vehicle is shown in Fig. 2. The prime-mover E drives the central member e of the differential gearing, the two outside members of which are connected; one to the armature of the generator G by means of a loose sleeve, and the other to the longitudinal transmission shaft d, which is connected to the driving-wheels through the ordinary differential gearing D', the armature of the electromotor being mounted also on this shaft. The armatures of the electromotor and generator are connected through a special controller, so that varying amounts of current may be transmitted between the two in order to vary the relative speeds of the motor E and driven shaft. In the ' off' position of the controller, the generator field circuit is broken, and its armature is consequently driven through the differential gearing at double the speed of the motor E, while the vehicle remains stationary. On closing the generator field circuit, the magnetic resistance to its rotation imposes a torque upon the driven shaft d, which is increased by supplying the current from the generator to the electromotor fixed on the driven shaft. Fig. 3 shows the controlling- switch C comprising nine stationary fingers f and having movable contacts on a rotating cylinder shown developed on a plane surface. Seven positions are shown, but a greater or less number may be used, if desirable. In the change - speed positions 1, 2, 3, 4, the arrangement of the circuits is shown in each case by the corresponding diagrams 1<Î>, 2<Î>, 3<Î>, 4<Î>, Fig. 4, the driven shaft of the vehicle increasing in speed between the positions 1,4. The braking effect is produced by moving the handle to the positions 1<1>, 2<1>, 3<1>, which cuts the generator out of circuit and connects the electromotor through a decreasing resistance R, finally short-circuiting it on itself in the position 3<1>. The arrangements for rotating the controlling - switch are seen in Fig. 5, the pivoted pedal I engaging the brake lever J at i<1>, and also carrying a toothed segment h, which gears with the pinion b mounted at the end of the contr,oller shaft. Depressing one pedal raises the other, and in the ' off ' position the brake pedal J abuts against a spring s, by the compression of which the switch is rotated into the braking positions. The switch may be locked in any position by means of the star-wheel K, Fig. 7, and spring- pressed pawl k. A reversing-switch is provided at S, Fig. 3, which is separate from, and independent of, the main controller switch.
