Title: Improved Process for Treating Sulphide Ores or Compounds Preparatory to Smelting-
Inventor: HUNTINGTON THOMAS
Filed: 1903-06-16
Granted: 1904-06-16
Abstract: 13,454. Huntington, T., and Heberlein, F. June 16. Sulphurous acid.-Relates to improvements in the process described in Specification No. 3795, A.D. 1897, and consists in first roasting the sulphide ores, mattes or metalliferous compounds, (particularly lead, zinc, copper, iron and like sulphides), in a furnace with access of air until the proportion of sulphur is sufficiently reduced, and then rapidly cooling them to the temperature of the air by means of water or other cooling agent. The ores are then in a suitable physical and chemical condition for the succeeding operation, which consists in placing them upon a layer of hot ore or fuel through which a current of air is forced. Tha sulphur is then entirely given off as sulphurous acid. The roasted ore and gangue are then ready for transference to a blast furnace for reduction. The Provisional Specification states that the process is suitable also for ores containing silver and gold sulphides.

Title: Improvements in and connected with Electrical Signalling on Railways and Tramways.
Inventor: TUNSTALL JAMES WOODS
Filed: 1903-09-03
Granted: 1904-12-03
Abstract: 18,980. Tunstall, J. W. Sept. 3. Electric railways and tramways, signalling on; contacts, electric; lamp signals.-In a system of signalling on tramways and railways where there are single lines and loops, two coloured lamps or semaphores are employed at the ends of each loop, and are connected through switches arranged so that when entering the single section the similarly-coloured lamps are extinguished at each end, and re-lit when the vehicle emerges from the section. Fig. 1 shows the connection of the switches for the red lamp at each end of the single line when occupied by a vehicle, the lamp being unlit. The form of switch is shown in Fig. 5, where the revolving switch arm 2 is operated by the tongue 7, Fig. 3, through the pawl 9 and gearing 10, 11, 12. The arm 2, Fig. 5, is in the form of curved springs which firmly engage the recesses 4 after each move. In another arrangement, shown in Fig. 2, only one wire is used for each lamp circuit. The lamps are extinguished by the switch device, Fig. 10, (type B), and re-made by the switch device, Fig. 9, (type A). The car travelling in either direction first passes the type B device, catching the tongue 7, and raising the spindle 22 and bridge contact-piece 23. This breaks the circuit and causes the armature 18 of the solenoid 14 in the type A device to fly back. The withdrawal of the pin 21 allows the piece 16 supporting the contact-piece 17 to fall, and the circuit remains broken and the lamps are extinguished. When the car, emerging from the single line past the type A device, raises the tongue 7 and thereby the piece 16, the circuit is again completed through the contact-piece 17 and solenoid 14. The pin 21 flies outwards and supports the piece 16, thereby maintaining the circuit until another car enters from the other end again.

Title: Improvements in Typewriting Machines.
Inventor: FELL JOHN CORRY
Filed: 1903-09-28
Granted: 1903-11-05
Abstract: 20,849. Fell, J. C., [Union Typewriter Co.]. Sept. 28. Type-writers.-Relates to means for excluding dust or grit from the bearings of the type bars or carriers. The carriage, provided with a platen 3, travels on a top plate 2 carried by the framing. To each key-lever 4 is pivoted a sub-lever 7, the lower part of which is slotted to engage with a fixed fulcrum bar 10 which extends across the machine beneath the key-levers. The upper end of each sub-lever is connected by a link to a pivoted type bar 14, the free ends of the bars being supported on a segmental pad 15. The bars are pivoted in slots 18 in a segment 17 which is provided with arms 15<a> for supporting the pad 15. The depression of any finger key causes the associated type bar to move upwardly and rearwardly to the printing-point Z. A universal bar 19, extending beneath the key-levers, is connected by arms 20 to a rock-shaft 21. The rock-shaft is connected by arms 22, 25 and a link 23 to another rock - shaft 26 which actuates the escapement. The arm 22 is also connected to one arm of a bell-crank lever 31, the other arm of the lever being connected by a link 35 to an ear 37 which extends rearwardly from a segmental dust shield 38, which is located above the type bar pivots and lies between the front face of the platen and the bearings. The ends of the shield are connected to movable guide-bars 39 which are supported by grooved rollers 40. When a key is depressed, the dust shield is drawn back by the bell-crank lever out of the way of the type bar as it moves to the printing position. When the key is released, the shield is drawn back to its normal position by springs 42, connected to the guide-bars 39. In a modification, the guide-bars and rollers are dispensed with, the shield being provided at the sides with rearwardly extending ears 44, Fig. 4, which are connected to links 46 pivoted at their lower ends to brackets 48 which extend rearwardly from the segment 17<a>. The shield is withdrawn by a bell-crank lever 31<a>, as before, the links 46 turning about the pivots 47 as the shield swings to the rear. Pins 46<a> prevent the shield from dropping too far forwards. In both arrangements, the shield is carried by, and shifts vertically with, the segment 17<a> when the latter is shifted for upper and lower case writing. The links permit this motion to take place without disturbing the bellcrank lever or the sub-levers. The segment is provided with vertical grooved guide-ways 49, Fig. 2, containing antifriction balls 50 which also run in fixed grooved guids-ways 51 in the framing of the machine.

Title: Improved Means applicable for Charging Bottles and the like with Liquids and Applying Seals or Stoppers thereto.
Inventor: NASH RICHARD GRAINGER
Filed: 1903-10-15
Granted: 1904-09-08
Abstract: 22,240. Nash, R. G. Oct. 15. Bottling; stoppering.-In machines for bottling aÙrated waters, beers, soda-milk, &c., means are provided for firmly gripping the seal or stopper while being applied, for minimizing risk of breakage while a bottle is being filled and sealed, and for obtaining a uniform flow of liquid to the bottle. For holding the stopper or seal, a cylindrical block A is screwed or otherwise attached to the lower end of a rotatable shaft B, and provided at its lower end with a collar a; around the block A is a sleeve a', formed at its lower end with saw-cuts a<3>. A spring a<4> is coiled around the sleeve, and over all is a casing a<5>, which abuts at its upper end against a slide b, and at its lower end against a conical shoulder a<6> formed upon the sleeve a'. In operation, a screw-cap or stopper is placed in the depending portion a<2> of the sleeve a', and the slide b is lowered until the screw-cap is in contact with the mouth of the bottle, the shaft B being meanwhile rotated. The weight of the slide b resting on the casing a<5> operates to grip the seal tightly. The slide b, which also actuates the charging-nozzle as described in Specification No. 7828, A.D. 1902, is raised by means of a roller b<1>, Fig. 4, engaging a cam b<2>, the roller being kept in engagement with the cam, during the raising of the slide, by means of a spring-controlled bell-crank lever c, formed with a head c<2> which passes through a slot c<3> in the cam-disc C. In order to minimize the risk of breakage when the filling-head or the sealing-device is applied to the bottle, a weight d<1>, Fig. 6, loosely mounted on a rod d<2> and resting upon a spring d<3>, is suspended from the arm D which actuates the cam d for the purpose of raising the bottle. As the bottle is raised, the weight is lowered, and the spring serves as a cushion to mollify the blow caused by the contact of the bottle with the filling or sealing devices. To ensure a uniform flow of liquid to the bottle, a receiver or tank is placed between the supply pipe and the filling-bead, and the liquid passes into this receiver through a perforated pipe, the perforations being preferably arranged so as to direct the incoming liquid against the sides of the receiver above the level of the liquid.

Title: Improvements in and relating to Apparatus for Indicating or Recording Speed.
Inventor: COWEY LEONARD EUGENE
Filed: 1904-12-27
Granted: 1905-12-14
Abstract: 28,477. Cowey, L. E. Dec. 27. Speed indicators ; registering observations by instruments; dials; driving-mechanism for record strips. -A speed indicator of the type described in Specification No. 1375, A.D. 1901, is provided with means for temporarily recording the speeds, say for the last 800 yards covered by a road vehicle, in the form of a flexible band wrapped around a cylinder, movable points adjusted on a dial to form a speed curve, or a series of small number-bearing discs suitably set. Figs. 1 and 2 show the first form, in which a roughened cylinder B is constantly rotated from the road wheels, and an endless band B<1> under slight tension is laid upon it by a groove or guide-pulley carried by a rack b<3> operated by a segmental wheel upon the spindle of the speedindicating band and moving between buffers. The graduations upon the cylinder represent speeds between ten and thirty miles per hour, and the scale b<8> shows the distances backwards in yards at which the corresponding speed records were made. The band if inelastic passes -at one pont over a pulley held by a spring which maintains a slight tension. In the arrangement shown in Fig. 5, the road wheels drive an annular disc carrying a curved slot b<9>, in which move indicating-points b<10> on arms b<11> pivoted to the disc. These indicating-points are all brought to similar positions by the fixed deflecting-pieces c<5>, and are then immediately displaced according to the speed at the moment by other guides c upon a segment C pivoted at c' and moved by the segmental wheel upon the index spindle. The points are viewed through a transparent annular segment, ruled with concentric lines according to a speed scale and graduated in yards backwards along the interior edge. In modifications, the arms may be dispensed with, the points may work on wires or bars, or alternatively the slotted plate may be dispensed with. In the third form, shown in Fig. 9, the small indicating-discs are carried upon a circular plate D<1> revolved by the road wheels, the numbers are read through small apertures in the screen A<4>, and the discs are set to zero by engagement of their opinions with a spring- controlled rack d<7>, pins determining the zero position. The setting is effected by a rack d<2> actuated from the index spindle and provided with a hinged upper segment, which bends and rotates the pinion as it passes.

Title: Improvements in or relating to Gyroscopes.
Inventor: ANSCHUETZ-KAEMPFE HERMANN
Filed: 1905-03-25
Granted: 1906-03-01
Abstract: 6359. Kaempfe, H. Ansch³tz-. March 26, 1904, [date applied for under Patents Act, 1901]. Gyroscopic apparatus.-Relates to a gyroscope, particularly for use on ships, as a substitute for, or as a means for corroborating or correcting, the magnetic compass, but applicable generally. Spinning bodies 1 are carried by horizontal axles 3. shown arranged vertically in Fig. 1 but horizontal when in operation, operated by a motor 2 mounted on a frame 4. This frame carries ball bearings for the axles 3, and turns on spindles 6 mounted in bill bearings carried by a suspended frame 9. The centre of gravity of the frame 4 and the parts carried by it is arranged below the point of intersection of the three axes of rotation, so as to cause the system to be acted on by gravity in such a way that the readings of the instrument are not effected by the earth's rotation, but are effected only by changes in the ship's course. The frame 9 is suspended from a float 10 in a liquid-container 11, supported in gimbals as shown. The float carries a pointer, to indicate the ship's course on a compass card 43, and is connected by a disk 12 and a nave 13 to a pivot 15 turning in ball bearings. The pivot 15 is connected by a spring 21, a piece of flexible shaft, or other elastic means to a pin 19 on the suspended frame 9, so that the gyroscope is not affected by shaking motions of the ship. The and 20 of the pin 19 is allowed a slight lateral play relatively to the annular piece 22. The motor 2 is connected to the axles 3 by spiral springs 24, flexible shafting, magnetic or other couplings which permit a limited relative motion of the coupled parts, or other elastic means. Current is supplied to the motor through a terminal 26, a conductor 27, a brush 28, a ring 29, a conductor 30, a leaf spring 32, a contact-screw 33, a silver wire 34 passing through the hollow axle 6, and a spring contact 35 connected to one brush of the motor. The other brush of the motor is connected to a similar arrangement of conductors or to the framework of the apparatus. The position of the centre of gravity can be adjusted by movable weights 44. Instead of the centre of gravity being arranged below the intersection of the three axes a spring or an electro-magnet may be used. Instead of two spinning bodies with one motor being used, two motors may be used, one on each side of one spinning body, or a single spinning body may be arranged to rotate in a central plane about the housing of a single motor. The apparatus is enclosed in a casing 25. Fig. 2 shows a modification in which the whole casing 25 floats in alcohol or other liquid in a vessel 36, a spring 40 being interposed between the casing and a pivot 37 running in a stone 38 at the bottom of a receptacle 39 containing mercury. The electric current enters the apparatus through the pivot 37, and may leave it through a rod or wire 41 dipping into mercury in a channel 42.
