Filed: 1903-05-22
Granted: 1904-04-14
Abstract: 11,727. Carolan, E. A., [General Electric Co.]. May 22. Current meters.-In order to cause a pivoted indicating-arm 14 to mark correctly on travelling paper 19, the paper travels across a stationary straight edge, and the arm 14 carries an edge 15, which is brought into contact with the paper to mark it at the point of crossing of the two edges. For this purpose a transfer ribbon 24 may be supported over the paper, below the arm 14. The marking-edge 15 may be curved in a plane parallel to the paper, to obtain any desired scale for the record relatively to the deflections of the arm 14 The marking-edge 15 may be constantly in contact with the paper, or may be intermittently pressed down by an arm 30 of a vertically-sliding rod 31, which is reciprocated by the armature lever of an electromagnet acting in opposition to springs, the circuit of the electromagnet being made and broken automatically by a contact spring. The transfer ribbon 24 passes between rolls 25 and over projecting edges 28 on a supporting-bar ; the ribbon and record paper are guided by pins on this bar. The invention is also applicable for recording on a revolving disc, the straight edge being placed radially. The recording-apparatus is shown as applied to a volt-meter, the arm 14 being attached to a vertical pin, and further supported by an inclined wire 18 attached to an upright 16, carried by the vertical pin. This pin and a lower pin in line with it are attached to an open rectangular coil, and connected to supporting and connecting springs ; the lower pin rests on a pivot. The rectangular coil turns between two stationary coils in a frame 4, and surrounds a cylindrical magnetic core, supported by screws. The movable coil carries a constant current, while the pressure to be measured is applied to the stationary coils. Stops 14<1> limit the turning of the arm 14.

Filed: 1903-06-04
Granted: 1903-07-09
Abstract: 12,644. Spooner, A. F., [Magnetic Ore Separating Co. Proprietary]. June 4. Treating ores; washing ores etc.; zinc.-Zinc blende is separated from crushed ores, concentrates, &c., by submitting them in a sufficiently wet condition to the action of chlorine, gaseous or otherwise. The blende particles are so acted upon that they adhere together, forming small masses when subjected to a vanning-motion, and can thus be separated on a vanning-table or belt. Any zinc which passes into solution is recovered separately. If the ore contains galena, undue action of the chlorine thereon is prevented by the addition of a soluble sulphate of zinc, soda, &c. The chlorine may be obtained from the electrolysis of zinc chloride, or an easily-decomposable compound of chlorine may be used in solution to replace or supplement the gaseous or dissolved chlorine.

Title: Improvements in Sheet Metal Radiators
Inventor: KINNEAR WILLIAM RAYMOND
Filed: 1903-10-16
Granted: 1903-12-17
Abstract: 22,375. Kinnear, W. R. Oct. 16. Metal, sheet, seaming and joining.-Relates more particularly to the jointing in sheet-metal radiators of the form in which flattened or elliptical tubes for the hot water or steam are fitted with a concentric tube so as to allow the air of the room to circulate therein and become heated. The ends of the outer tubes A, Fig. 11, are bent inwards at an angle and united to the enlarged ends of the inner tubes B by a seam ; or the ends of the inner tubes may be bent back as at 3<a>, Fig. 10, the corner pieces 3<ax> being fitted separately. The connections F, I are made by stamping and punching the flat sides of the tubes into the form shown in Fig. 17. The edges 7, 9, Fig. 19, of the opposed openings 8 are then united by folding one over the other. This is effected by means of three grooved rollers 10<a>, 10<b>, 10<c>, Fig. 22, carried in a suitable frame and forced outwards by a mandrel 11. In making the blind connections H, the metal of an outer tube is first stamped into the form shown in Fig. 13 and then pressed by suitable dies into the form shown at 12, Fig. 14. The boss 12 is placed in the opening in the adjacent tube and secured in position by a groove formed by the edges of the rollers as indicated in Fig. 15. The nipples 14, Figs. 23 and 24, for the attachment of the flow and return pipes, are formed with depressions 15 into which the metal of the boss 16 is pressed. The parts are then secured by soldering. The depressions in the parts 14, 16 may be formed separately so that they fit together when drawn up tight by the nut 19. The nipple may also be secured as shown in Fig. 3 by spinning the metal of the boss 16 into a groove 15<a>. The tubes B may be fitted with tubular stays 20, Fig. 5, held in place by stamped bosses 21. -

Title: Improvements in Decorticating Machines.
Inventor: POS GERRIT MARIE ELIZE
Filed: 1903-10-27
Granted: 1904-02-25
Abstract: 23,263. Pos, G. M. E. Oct. 27. Decorticating ramie, china grass, aloe, agave, &c. -The material 54 rests on the hopper-screen 37 with its ends against the side 38 of the hopper. The lower layers of material are then caught by the pusher 39 fixed on an arm 41 loose on the shaft 2. The pusher is advanced by a pin 40 fixed to the slowly-rotating flanged drum or carrier 3. After a time, the pin 40 escapes from the pusher which falls back to the left by gravity. The material is thus pushed into a slot 13 in the drum. It is gripped by the pivoted gravity grip 14 when the tail 16 of the grip has escaped from the fixed piece 18. The material is then pulled round by the drum, and carried beneath the rollers 9, the rotating decorticating-drums 4, 10, the scraper 28, and brushes 33, 34 until it is pulled out from the gripper, which has now fallen into an open position, by the piece 35 fixed to the rod 44 connected at one end to the eccentric 43 and at the other end to the arm 46 loosely pivoted to the shaft 2. The material then passes over the brush 36 to a conveyer. The brushes 34, 36 are provided with bristles in right and left helical threads, so that the fibres are swept into three or more heaps. The drum 10 is rapidly rotated, and is also reciprocated by the connecting-rod 21 and crank 22. The knife or scraper 28 is pivoted to the loose arm 31, and is reciprocated by the connecting-rod 27 and crank 22. The connecting-rod 27 is connected to the knife holder 30 at the point 32 so that the knife operates only during its forward movement. The pusher 39 carries a sliding spring-actuated plate 56 which keeps the fibres 54 from falling down indiscriminately. The pusher 39 may also carry a slitting- knife 47, Fig. 4. This is brought into action by the lever 48 when it strikes against the fixed pin 51. The pusher and knife are kept in place by a catch 52 which is liberated, when the material has been drawn away, by the weighted bell-crank lever 49.

Title: Improvements in Automatic Relief Valves
Inventor: BECKETT EDWARD HENRY
Filed: 1903-11-04
Granted: 1904-09-08
Abstract: 23,939. Beckett, E. H. Nov. 4. Safety-valves; shocks, preventing.-To prevent shocks in closing, automatic relief valves for exhaust steam, gas, &c. are constructed as follows :- A cylindrical valve A works over a fixed piston B and bears upon its seating in the ordinary manner. One or more auxiliary valves 0 are fitted to the piston B which, if hollow, is provided with a drain hole P. If the pressure rises above a certain point, the valve C opens and allows the steam &c. to pass into the space above the piston B thus causing the valve A to rise from its seating. When the pressure falls, the valve is prevented from closing suddenly by the steam &c. which is enclosed in the space above the piston and can only escape slowly through the hole P and by leakage past the piston B. A lever E and weight G are provided to adjust the pressure at which the valve will open.

Title: Improved Means for Operating, Controlling and Locking Gates or Barriers for Level Crossings on Railways, or the like.
Filed: 1903-11-16
Granted: 1904-09-22
Abstract: 24,945. Westinghouse Brake Co., and Malan, E. de M. Nov. 16. Crossing-gates &c.-Relates to means for operating, controlling, and looking, from a distance, gates or barriers for level crossings on railways or the like, and is particularly applicable to gates which are actuated by fluid-pressure apparatus. Fig. 1 is a diagrammatic sketch showing one form of the arrangement suitable when the gates or barriers are constructed without stops. The admission of motive fluid to the motor 1, for operating the gates, is controlled by the electromagnets 2, 3, and the exhaust by the check valve 8, which is connected to the controlling-lever 4 so that it is normally closed. The lever 4 opens one and closes the other, according to the direction of its motion, of the two motor contacts 5, 6, and, in its central position, opens the valve 8, the contacts 5, 6 being constructed so as to admit of sufficient movement of the lever 4 from its central position to operate the exhaust valve so as to control the movement of the gates as desired without reversing the motor. The gate, in its full open and closed positions, operates the switch 10, thus closing one and breaking the other of the two circuits which are utilized to operate the electromagnetic locks 14, 15. The lever stops are arranged so that the lever 4 cannot be moved right over until the lock circuit has been closed through the switch 10. A modification of the arrangement is shown for the case in which ordinary gate stops are used. In this case, a separate motor, controlled by a separate stop lever, is used to operate the stops ; the two levers being interlocked so that the gate lever cannot be operated until the stop lever has been moved over. A further modification is described for the case in which the gates are provided with locked stops. In this case, two motors are used for operating the stops, one unlocking and lowering one set of gate stops and raising the other set, and the other locking the raised stops when the gates have been moved into their new position.

These latter slots may be closed for the purpose of regulating the draught by means of filling-pieces 10, one of which is shown separately in Fig. 5.
Patent GB-190404664-A (GB)
Title: Improvements in Railway Brakes.
Inventor: HALLOT PAUL
Filed: 1904-02-25
Granted: 1905-02-23
Abstract: 4664. Hallot, P. Feb. 25. Brakes.-The pressure of the blocks on the tyres is regulated, so as to prevent the wheels from skidding, by utilizing the relative movement of fast and loose devices on or connected with the axles for affecting the pressure in the brake cylinder. The apparatus shown in Fig. 1 comprises two cams d pivoted at the ends of a diameter of a sleeve b keyed to the axle a, and entering recesses i in a heavy ring h<1>, which has a small rotatory movement, limited by stops, relative to the sleeve b. If the speed of the axle diminishes, the ring h<1> turns the cams d so that they force the ring i<1> along its guides e<1> until it operates the fork k or other device connected to the pressure-reducing mechanism. Adjustable springs j immediately return the apparatus to its normal condition. The modification shown in Fig. 5 consists of two pulleys r, r<1> loose on the sleeves n, n'. The sleeve n<1> is keyed to the sleeve b on the axle, and the sleeve n is loose and is driven by projections p engaging with the ends of segmental recesses m in the sleeve b. Radial projections or partitions on the sleeves n, n' drive the heavy masses q, q<1>, which tend to rotate the pulleys r, r<1>. If the axle stops running, the pulley r moves relatively to the pulley r<1>, so that the cord s moves the lever t and releases the brakes. Flexible metal strips r<x> prevent the entrance of dust &c. The apparatus may be mounted on an axle 1, Fig. 7, which is rotated by the axle a when the band 2 is tightened by the pulley 4, lever 3, and brake mechanism 5. In a modification, the band 2 is driven by the axle of a friction pulley, which is drawn up to the axle by the brake mechanism, and then drives the heavy masses q, which, flying outwards centrifugally, drive the pulley 14 and move the rack 17 to the right. If the axle stops running, the pulley 14 is released, so that the spring 18 draws the rack 17 to the left, and operates the hammer 21, which pushes in the rod 22 for operating the pressure-releasing valve 23 on the brake cylinder 24. The cords 16 for each axle may be connected to the ends of a flexible rod extending longitudinally and operating, by cams or other means, the pressure-releasing valves, which rod may also be used with the device shown in Fig. 7 and the modification described above. The valve operated by the cam 36, Fig. 13, and the flexible rod 28 consists of a valve 37, which is raised by the conical valve 40 as it tends to close the passage 41.
