Granted: 1905-11-09
Abstract: 12,320. Greenawalt, J. E. June 13. Roasting' &c.] furnaces; hearths; air and gases, supplying; cooling.-A reverberatory roastin'g-furnace, which is adapted for the treatment of the ores of gold, silver, and other precious metals, but also applicable generally, is provided with a porous hearth 8, Figs. 1 and 3, through which air, gas, or steam is supplied to the ore under treatment. The porous hearth is composed preferably of the same kind of ore as that being treated, but it may consist of fine sand, mineral wool, fibrous asbestos, or the like. It is supported upon a hearth of cement which rests upon a foundation of concrete, and is divided into sections by walls 23, Fig. 2, extending nearly to the lowest point of the rabbles. Each section communicates with conduits 5, which are arranged at the side of the furnace and to which air and steam under pressure are introduced through pipes 9, 17, 10. By this arrangement, it is possible to control the amount of air delivered to the ore at the various stages of the roasting operation. The tracks 14 upon which run the truck wheels 13 of the rabbles are made hollow and cooled by a water pipe 15. They are provided with flanges to which are bolted tiles 16 for enclosing the hearth ; Fig. 3 shows a hollow track 14<c> with its interior open to the atmosphere. Fig. 3 also shows a modified form of porous hearth applied to a furnace in which the ores are stirred by hand rakes or hoes. The hearth is formed of bricks arranged with spaces of about an inch between them filled with loose material and supplied with air as described above. This arrangement is also adapted for use with poweroperated rabbles. The ore is fed to the hearths of these furnaces from a hopper 24, the supply being regulated by a gate 25 or by adjustment of the sprocket-wheel 27. The latter is mounted in bearings which may be adjusted by screws 28 to tighten the rabble chains and at the same time to cut into the ore to a greater or lesser extent to regulate the feed of ore. The furnace is preferably heated by producer gas, which is introduced at the inlet 29, Fig. 2, and passed over the hot roasted ore in the pit 30 before it escapes through the opening 31 to the furnace.

Granted: 1906-07-19
Abstract: 14,839. Hollick, W. J. July 19. No Patent granted (Sealing fee not paid). Crossings; crossing - gates. - Apparatus of the type described in Specification No. 18,468, A.D. 1904, is connected to, and arranged to be operated simultaneously with the movement of, railway points, signals, crossing- gates, or a separate lever in the signal cabin. The lever which, in the prior Specification, was described as being depressed by the wheel flanges of the railway vehicle, may be used as a supplementary operating means, or may be omitted. In Figs. 1 and 2; showing the branch line of a railway crossed by a tramway track, the movable blocks a, mounted on links f at the side of the railway rails o, are connected to shafts d by pins c working in slotted levers b. The shafts cl are all connected by arms to a rod j which is connected by suitable rods and bell-cranks m either directly to the points, or to the point-operating lever. In a modified construction, the rodj is connected to a pivoted lever, mounted transversely to the railway track, and the latter lever is operated by a chain coiled on a wheel at the base of a crossing-gate. In the latter case, springs are mounted on the shafts d to restore the blocks to their original position after being operated in one direction. The Provisional Specification states that the pins c may be omitted and the ends of the movable block connected directly, or through linkwork, to the operating-mechanism, or wedge-shaped blocks or cam-levers for supporting the movable blocks may be linked to the operating- mechanism. [Reference has been directed under Patents Act, 19U2, to Specification No. 26,498, A.D. 1897.]

Title: Improvements in and connected with the Propulsion of Railway, Tramway, Road or similar Vehicles, Boats and the like.
Inventor: HART ERNEST WILLIAM
Filed: 1905-08-25
Granted: 1906-07-05
Abstract: 17,248. Hart, E. W., and Durtnall, W. P. Aug. 25. Electric locomotives and motor vehicles.-Relates to the electric transmission of power on railway, tramway, or similar vehicles, boats, &c., employing a petrol, gas, or steam engine or a turbine as prime mover, and consists in using a generator having a revolving magnet or magnets and a stationary armature, so as to obviate the use of a commutator, the windings being preferably arranged for polyphase alternating currents. In addition, means are described for regulating the supply of fuel to the prime mover and for cooling the windings of the motor and generator. Fig. 1 shows the electric connexions, and Fig. 2 is an elevation of a vehicle with the invention applied. A single or multiple field-magnet a is mounted on the shaft b of a petrol or other motor c, for which it may act as a fly-wheel, and is arranged to revclve within or without a stationary armature d. The field-magnet a of the main generator is excited by a small generator e, controlled by a switch, which thus indirectly controls the output of the generator. From the armature winding d, three or more conductors f pass to the winding g of the stator of a polyphase alternating-current motor, the rotor h of which is of the wound or squirrel cage type. The shaft of this rotor is connected through differential gear to the road wheels. Between the generator and motor a magnetic clutch u is fitted so that at the highest speed a direct drive may be obtained. The switch, when swung into contact with the stud v, divides the current from the source e between the field a and the clutch u, and when swung into contact with the stud w, all the current passes through the clutch, the field a being shortcircuited by the bridge contact z. Instead of regulating the current in the generator field a, the shunt field of the exciter e may be regulated by an adjustable resistance. The vehicle may be started by running the exciter e as a motor, and means may be provided for electric braking. The supply of fuel to the prime mover may be controlled by suitable means, for example, the valves may be electrically operated and controlled from the switch. Owing to the absence of commutators or brushes, the generator or motor can bear abnormal loads for a short time without excessive sparking. Forced ventilation may be employed for the generator and motor, the windings being arranged so that they generate a draught while revolving, or fans being attached. The petrol motor, dynamo, and electromotor are mounted on an auxiliary frame, connected by vertical spiral springs with the main frame so as to minimize vibration,

Abstract: 23,878. Bastiano, J. H. Jan. 6, [date applied for under Patents Act, 1901]. Disengaging couplings and devices.-Relates to a locking-device for suspending arc lamps and the like, combined with electric couplings, and consists in improvements on the apparatus described in Specification No. 2676, A.D. 1904, [Abridgment Class Electric lamps &c.]. Fig. 1 shows the apparatus in the locked position, Fig. 2 being a plan view with the upper part removed. The fixed part of the device consists of a tube A with longitudinal slots for the balls K, and having its lower end shaped to guide the stem into its correct position when being raised. The stem B is rigidly fixed to the hoisting-rope, and has an enlargement at its upper end adapted to engage the balls K. The cap H, which carries the plug contacts F, F<1> is mounted to slide on the stem B, and when in its lowest position rests on a projection M. The balls are kept in position by a sliding sleeve L provided with recesses L<2>, L<3> normally above and below the level of the balls. The cap H carries a piece N which encloses the stem B and has on one side a projection fitting into a slot in the fixed tube A. When it is desired to lower the lamp, the stem is first raised until the cap H engages the projections X and lifts the sleeve until the balls are free to roll outwardly ; on subsequently lowering, the sleeve is sustained in its upper position by the friction of the contacts F, and the lamp is free to descend. When the projection on the sleeve B reaches the piece N, the cap H is forced down and the sleeve L falls and presses the balls inwards. When the lamp is raised again, the balls are pressed upwards and outwards into the recesses L<2>, and when the projection on the stem has passed, the balls roll back again and afford a support for the lamp.

Abstract: 14,700. Clement, N. June 27. Bedsteads; mattresses.-In invalid and like bedsteads of the kind described in Specification No, 19,954, A.D. 1900, comprising a main frame and extension frames pivoted thereto, the extension frames are held by a ratchet device, formed in corner castings, in any desired position. The main frame consists of legs 1, connected by crossbars 3, Figs. 5 and 8, and by longitudinal bars 5, the joints being made by corner castings 4, connected to the legs by clamps 42, a cover-plate 4<1> on the casting 4 and a similar one on the side bars preventing the bedding from entering the joints. In each of these castings 4 ratchet teeth 13 are formed, with the teeth of which the toe-pieces 16 of the side bars 8 engage, these side bars, pivoted at 10 to the casting 4 and stiffened by cross-pieces 9, forming the extension frames 6, 7. To lugs 14 on the bottoms of the side bars 8 is pivoted a bail 15 ; the middle portion of this bail passes through openings 12 in the castings 4 and also engages with the ratchet teeth, dropping by gravity between the teeth and a toepiece. The bail 15 is held out of engagement with the teeth by a lever 19 actuated by a footlever 21 mounted on a bracket 18. The end frames 23, 24 are pivoted, at the end of the posts 25, to the side bars 8, and are adjustable with respect to those side bars by means of the ratchet plates 26 and pawl 30. A slot 26<1> in one of the ratchet plates 26 receives the pivot on one of the posts 25, the hook 32 holding the pivot in place ; this arrangement allows the end frames to be removed from the extension frames 6, 7. To the plates 26 is pivoted a bail 39 which holds up the mattress frame 33 when the extension frames are raised. When these frames are flat, the mattress rests on the main frame. The mattress, which comprises a main rectangular frame 33 and a wire-fabric bedding-support 34 preferably supported at its centre by a set of coil springs, is made longer than the main frame, but not so long as the main and extension frames together. To prevent endlong movement of the mattress, Y-shaped cuttings 38 are fixed on the mattress frame, and engage with the cross-bars 3 of the main frame.

Granted: 1907-11-14
Abstract: 25,981. Rankin, E., and Spicer, G. Nov.16. Braiding-machines, - Inner and outer sets of bobbins are mounted on co-axial spiders a, b, and are rotated in opposite directions by bevel driving- gear. The lower portions of carriers f for the inner bobbins pass through the centres of horizontal disks g, and are screwed to blocks p which slide on and are supported by the lower spider b. The peripheries g<1> of the disks g engage with a ring i and flanges i<1> of the spider a. The disks are rotated around the carriers by means of lower rollers n which gear into teeth m on the spider b. This movement allows thread-guides j controlling the outer set of threads to pass between the inner set of threads and the braiding point. The threadguides are mounted on levers k pivoted to the spider b, are provided with terminal rollers k<1>, and are operated by a stationary cam. This cam l is interchangeable, and it projects the thread-guides alternately outside and inside the circular path of the inner bobbins. In the latter case, the threadguide registers with a deep notch in the corresponding disk g and is thus conducted safely past the gear teeth m, the movement of the various parts being suitably timed for the purpose.
