Title: Improvements in Fittings for Centrifugal Separators.
Inventor: OHLSSON JOHAN ABRAHAM
Filed: 1903-07-09
Granted: 1903-08-13
Abstract: 15,229. Ohlsson, J. A. July 9. Cream separators.-In centrifugal drum separators having a number of plates arranged round the axis of rotation at short radial distances apart, extending from bottom to top of the drum and independently hinged at their outer edges, the plates 7, Fig. 1, and 8, Fig. 3, are disposed in such a way that their surfaces, of any desired formation, are inclined to lines parallel to the axis of rotation. The frame to which the plates are secured consists of the two rings 4, united by rods 5 and mounted on ribs 3. The angle of inclination of the plates may be varied in the same machine, for instance, they may be arranged zigzag. In Fig. 3, the plates 8 are shown as parts of cones about the axis of rotation of the drums and are intended for drums with conical casings. In this example, the milk is introduced into the separating space midway of the drum, the cream outlet being at the upper end, and the skim milk at the lower and broader end. The disc 9 is provided, to prevent the milk from falling immediately to the bottom of the drum. Instead of hinging the plates, they may be linked together at their inner or outer edges. The rings 4 may be grooved for holding the plates, and thus facilitating cleansing.

Title: Improvements in Centrifugal Machines.
Inventor: MACFARLANE JAMES WRIGHT
Filed: 1903-09-08
Granted: 1904-07-21
Abstract: 19,320. Macfarlane, J. W., and Macfarlane, W. A. Sept. 8. Brakes; driving.- The switch and mechanical brake of an electrically-driven centrifugal machine are so interconnected that the current cannot be switched on when the brake is in operation, and vice versÔ. Fig. 1 shows diagrammatically an arrangement applicable in the case of a shunt-wound or compound - wound motor. The switch lever A<4> is held in its fully-on position against the tension of the spring A<5> by a switch magnet A<2> having its coils in series with the shunt coil B' of the motor. To a lug on the brake band is attached a rod C<5>, having an insulated button, which keeps apart two contact springs D when the brake is off. When the brake is put on by means of the handled cam C<4>, the springs D, which are connected to the positive lead E and the shunt coil B<1>, respectively, come into contact, thus shortcircuiting the magnet A' and allowing the switch lever to be retracted by the spring A<5> so as to cut off the current. In the apparatus, shown in Fig. 2 and applicable in the case of a series-wound motor, the spindle of a switch of the double-pole type is extended and provided with a cam, which bears against a stirrup carried by the brake band, so as to put on the brake when the switch cuts off the current. In order that the blades A' may make a rapid break with the terminals A<1>, the insulating- discs G<1>, which carry the blades A<4> and are loosely mounted on the spindle C<5>, are connected by a spring G<3> to an arm G<2> fixed to the spindle C<5>. As this spindle is rotated, the spring is distended until the arm G<2> comes into contact with stops on the discs G'. Continued movement of the spindle forces the blades away from the terminals. The springs then cause the discs to rotate rapidly on the spindle so as to withdraw them from the terminals. The spindle of a three-pole switch for a three-phase alternating current motor may be similarly extended and connected to the brake mechanism. Fig. 5 shows an arrangement, appli. cable to a series-wound motor. The switch lever is held in the fully-on pcsition by a magnet A', the coil of which is in shunt with a resistance H in the main circuit. A rod C<5>, attached to a lug on the brake band, carries arms which make contact with terminals, arranged in the shunt circuit containing the magnet A<2>. When the brake is put on, the shunt circuit containing the magnet is broken. The lever is then retracted by a spring A<5>, and the current cut off. The invention may be applied to apparatus provided with mechanical brakes and and also to apparatus running on fluid bearings such as those described in Specifications No. 16,367, A.D. 1901, and No. 14,483, A.D. 1902, in which the braking is effected by cutting off the supply of fluid to the bearings.

Title: Improvements in Nuts
Inventor: SCHUBERT MAX
Filed: 1903-10-09
Granted: 1903-12-17
Abstract: 21,751. Schubert, M., and Rechnitz, 0. Oct. 9. Locking nuts.-Relates to a nut made in sections to be used upon intermediate parts of bolts or cores without reducing or screwing the ends, or between curves or angles as shown in Fig. 1. The nut is designed to facilitate the use of shallow threads, and also to facilitate it being locked in position, one application being in connection with railway rails. The threaded portion of the nut is made in two or more parts c, e, Fig. 2, which are placed upon the threaded core, and are enclosed by a sheath b. By placing an abutment or stop temporarily against the sheath and continuing the screwing up of the nut, the parts c, e pass into the sheath and are gripped tightly upon the core. The surfaces of the parts c, e, and the internal surfaces of the sheath may be roughened, or a set-screw may be passed through the sheath to secure the parts of the nut in position. The sheath may be divided as shown in Fig. 6 when the nut is used in places which are difficult to reach. Fig. 5 shows a threaded conical tube, which is divided alternately from opposite ends. In making the nuts, the ordinary tapping process is replaced by pressing the nut and mantles over suitable core bars.

Title: Improvements in Ticket Punches.
Inventor: PISCICELLI ROBERTO TAEGGI
Filed: 1903-11-23
Granted: 1903-12-31
Abstract: 25,540. Piscicelli, Count R. T. Nov. 23. Ticket punches.-A punching-machine for tram tickets is provided with separate compartments to receive the cuttings from tickets of different prices, and separate counters for each. A locking-device is also provided to prevent the working of the punch without a ticket. Fig. 2 shows a sectional side view, and Fig. 3 a view of the back of a machine having four compartments. A circular box 5 rotates on a stud 3 in a casing 1 having a quadrant shaped opening 2. The back part of the box is divided by four radial partitions, and each section has a hole 9 for receiving the discs, and a shutter 7 which can be removed through the opening in the casing after raising the bar 8. The punch 15 is connected to the hook 17 by a lever 16 and sliding bar 18, and is kept raised by a spring 19. A spring tooth 21 on the bar 18 acts on the short arm of a bell crank lever 22, the long arm of which carries the hammer of the bell 23. To bring the holes 9 underneath the punch, the knob 12 engages with the stops 13, except when the spring button 10 is depressed, and the box is constantly pulled in one direction by a spiral spring 14. The ticket pushes back the free end of a lever 26, Fig. 10, which otherwise locks the bar 18 by means of a pin 28. The motion of the sliding bar is communicated by means of the lever 29 to the counting-mechanism which is contained in the front part of the box, the numbers appearing through holes in the front plate. The arm 31, Fig. 4, connected to the lever 29, acts on one of the levers 32 and pawls 33 which work the ratchetwheels 34 of the four trains of counting-wheels, shown in Fig. 7. The arrangement for setting the wheels to zero is shown in Fig. 9. A series of twelve spur-wheels 41, all in gear, is worked by the pinion 43, with a key, and the ends 46 of the clicks 44 engage with pins 45 which project from the long arms 36 of the counting-wheels.

Title: Automatic Back and Fore Grip Free-wheel, suitable for Cycles and other Machines
Inventor: TURNER ALBERT RICHARD
Filed: 1903-11-27
Granted: 1904-10-27
Abstract: 25,921. Turner, A. R. Nov. 27. Clutches ; bralces.-In a free-wheel clntch for cycles and other machinery, rollers or like gripping-means are adapted to be pressed into contact with a ring on the hub, so that driving may be effected in either way that the sprocket is turned. The rollers D are supported in slots in a pair of side-plates B which are received by flanges on the sprocket-wheel A provided with a hollow hexagonal centre. Three or more bearer-plates G, each having a doubled and turned-np projection H, are mounted upon the side-plates, as shown in Fig. 3, and the trunnions of the rollers rest on springs E. A cam K, Fig. 5, the pressure upon which is regulated by a screw N and spring 0, is so mounted in a detachable bearer that, when pedalling is begun, one of its points L engages a projection H and so holds the side rings stationary. The continued rotation of the sprocket, through the plane inner faces, causes the rollers to move towards the centre till they engage a ring I fixed to the hub, and driving is thus effected. Meanwhile, owing to the motion of the rollers, the points H have also moved inwards, and the cam then turns up into the position shown in Fig. 5, the side rings being set free. When pedalling is stopped, the rollers move back to the corners, and the projections H again assume a position suitable for engagement with one of the points of the cam when driving is resumed. In a modification, friction blocks, hinged at one end on the shouldered screws F which hold the side rings together, and shaped to correspond with the inner face of the sprocket-wheel and the periphery of the hub ring, carry sliding pawls adapted to be brought down into engagement with recesses in this ring. On reversing the motion by back-pedalling, the blocks themselves engage the hub ring and exercise a retarding effect. No bearer-plates are used, but bearer-points, in the form of studs upon the tops of the blocks, project through the outer side ring. The Provisional Specification states that, if desired, for driving in one direction, only one cam projection may be provided.

Title: A New or Improved Process for Hard Soldering Cast Iron.
Inventor: MICHELIS CARL
Filed: 1903-12-02
Granted: 1904-09-01
Abstract: 26,376. Michelis, C., Michelis, L., Kruse, C., and Kuhn, O. Dec. 2. Soldering.-In hard-soldering cast iron, a firm coating of copper is electrolytically deposited from an alkaline bath on the parts, which are first cleaned from grease and oxide. The copper is deposited slowly, a current at 2À5 to 3 volts being used. By repeated cleansing with a wire brush and re-suspension, a sufficiently thick deposit is obtained. The surfaces upon which a deposit is not required may be coated with varnish, wax, pitch, paraffin, tallow, &c. The parts are afterwards soldered in the usual manner. The process may be used for soldering cast iron to other metals.

Title: Improvements in the electric Transmission of Power for Autocars and Automobiles.
Filed: 1904-02-10
Granted: 1904-06-02
Abstract: 3344. Soc. de Champrobert & Cie. Feb. 11, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Motors, controlling.-The power of a petrol, spirit, or steam motor is applied for the propulsion of a vehicle through the medium of variable electric transmission gearing. This comprises a shunt dynamo driven by the motor and supplying current directly to a series motor having several windings for the field and also for the armature, which may be variously combined by a suitable controller. The diagrams show the dispositions 'possible with two field and two armature circuits ; Fig. 2 shows the arrangement for high speed on the level, Fig. 1 that for giving an increased torque for ascending an incline, and Figs. 3 and 4, which are practically equivalent, show arrangements giving intermediate effects. The arrangement is such that the voltage, and consequently the vehicle speed, falls off very rapidly if the speed of the petrol or other motor is slightly reduced, and this enables the car to be stopped and started without having to break the electric circuits or to interpose resistance.

Title: Improvements in Manufacturing and Delivering Gas to Explosion Engines and other Places.
Inventor: LOOMIS BURDETT
Filed: 1904-03-10
Granted: 1904-09-01
Abstract: 5912. Loomis, B., and Pettibone, H. March 10. Gas-producers.- Relates to a process of, and apparatus for, making gas intended chiefly for use in explosion engines, but applicable also for other purposes. According to the arrangement shown in Figs. 3 and 4, the apparatus c o m - prises a set of three gas producers A, B, C, a boiler F for supplying steam to the producer, wet and dry scrubbers G, H, and a gas regulator I, which is connected directly with the supply pipe of the engine K. The producers are worked in rotation, the gas from the one which is being worked, say A, being drawn by the suction of the engine through the cross connections D, D<1> into the producers B, C, and thence downwards through the fires in them to the pipe E<2> leading to the boiler F. Air is drawn into the producers B, C through the charging-apertures a, the covers x of which are removed. Steam can also be admitted through the pipe S'. When the fire in the producer A gets comparatively dead, the steam blast from the pipe S is shut off, and the producer B started. At the same time, the producer B is shut off from the pipe E' and the producer A connected with it. The valves in the connections at the top and bottom of the producers serve to shut off any one producer from the rest for repairs &c. The exhaust from the engine is led back to the producers through a pipe M, and is utilized for making the gas and also for removing dust from the fires ; this dust passes over into the wet scrubber G, where it is deposited. An inert gas, preferably a mixture of nitrogen and carbonic acid, may be also employed in removing the dust. When the apparatus is applied generally, a fan withdraws the gases from the producers, and delivers them to a holder, or direct to the place where they are required.

Title: Magneto-Electric Igniting-device
Inventor: HAUPTMANN CARL
Filed: 1904-04-30
Granted: 1904-07-28
Abstract: 9914. Hauptmann, C. April 30. Magneto-electric machines.-Relates to a magnetoelectric igniting-generator, more particularly for motor cars, in which an efficient ignition spark is obtained, even when the speed of rotation of the generator is slow, by the insertion of an interrupter across the generator terminals. The generator consists of an armature having a number of permanent magnets a, in this case four, which rotate within a casing e carrying a number of coils mounted upon cores d. Each magnet is composed of a bundle of flat strips held together by rods passing between the discs b, as shown in Fig. 2. The current passes from the generator through a switch g and coil h which excites the igniting- device k, the interrupter l being inserted in shunt. The interrupter consists of a metal cylinder n, mounted upon the casing p, from which it is insulated, and having strips o of insulating-material upon its circumference. The brushes t are attached to springs fixed upon the ring s, which rotates with the shaft c, to which it is attached through suitable insulation, so that the generator is periodically short-circuited. As soon as the speed of rotation of the shaft c reaches a certain value, the brushes t no longer make contact with the cylinder n, owing to the action of centrifugal force, and the action of the interrupter consequently ceases. If desired, one of the terminals of the generator may be connected to the generator casing, in which case the insulation of either the brush ring s or the interrupter cylinder n would not be needed.

Abstract: 10,655. British Thomson-Houston Co., [General Electric Co.]. May 9. Stuffing-box packing.-A packing for piston-rods, valve stems, and the like consists of two interlaced helices of metal ribbon wound edgewise and tapered at the ends. The helices are sprung into place. One ribbon 5, Fig. 4, fits tightly to the inside of the stuffing - box, and the other 6 fits tightly on the shaft. In one method of tightening, each helix is fastened by a pin 8 to the stuffing-box, and the outer end of one helix is held by a set-screw 9. The outer end of the other helix engages with the serrated undersurface of a nut 10, the turning of which causes the helix 6 to grip the shaft more closely. The gland 4 serves to press the helices together. In a modification, the nut 10 is dispensed with.

Title: Improvements in Machines for Doubling and Twisting Yarns and Threads
Inventor: COLLINS HENRY
Filed: 1905-04-04
Granted: 1906-03-15
Abstract: 7116. Collins, H., and Collins, J. W. Nov. 7, 1904, [date applied for under Patents Act, 1901]. Special yarns, producing; rollers and roller heads; stop-motions; delivery, stopping.-Relates to machines for producing a compound yarn, say of cotton and wool, by feeding the former to the twisting point faster than the latter so that the cotton is wound spirally around the wool, and consists in providing means for stopping delivery of both yarns should either break. The cotton 34 is led from a spool 38 through a guide 39, and is drawn forward by rollers 7, 14 down to the end 20 of the stop-lever 16, where it joins the woollen yarn 33; the latter passes freely between the reduced part 13, Fig. 3, of the top roller 14 and the roller 7. and over the roller 13, and is fed forward, at a slower rate than the cotton, by the nip of the rollers 6, 13., Should either of the yarns break, the end 19 of the lever 16 will drop into the path of the rotating cam 5, which forces the lever outward and causes the frame 18 to which the latter is pivoted to slide with the guide-rods 24, 25, and thus displace the top rollers 13, 14, which are carried by a bracket 22 secured to the sliding frame. As the frame moves outwards, the end 37 of a clamping-device shown in perspective in Fig. 5, falls down between the frame and the side of the box 3, thereby jamming the yarns which pass through the recesses 32, 32 between the plate 35 and the fixed jaw 28 and effectually preventing any further delivery from the spools.
