Title: Improvements in Single Phase Induction Motors.
Filed: 1905-02-03
Abstract: 2180. Akt.-Ges. Brown, Boveri, & Co. Feb. 4, 1904, [date applied for under Patents Act, 1901]. Void. [Published, under Patents Act, 1901.] Armatures; motors, controlling.-The continuous rotor winding of a single-phase induction motor is short-circuited at a number of points, and is supplied from an external source with currents of approximately the same phase as the currents produced in the rotor winding by induction, in such a manner that the reaction of the two resulting fields gives rise to a uniform torque. The motor is controlled by regulating the externally - supplied current. In the bipolar machine shown in Fig. 1, the stator winding a is connected to the main terminals b, and the rotor c, short-circuited between the points e, f, g, is fed with current from outside by means of a commutator and brushes d. In the position shown, the external current flows from one brush d through the winding to the points e, f, and thence through the short-circuiting connexions to the point g and second brush d, giving rise to the fields indicated by dotted lines, which cross both at the points of entry and exit from the winding the induced field indicated by the lines z. When the rotor has moved round 60‹, a section of the winding opposite to the other brush d becomes active. A four-pole machine is shown in Fig. 2, with the rotor winding short-circuited at six points and furnished with four brushes d supplied with current through a reversing-switch p and a regulating-rheostat o from the secondary of a transformer t, the primary of which is in the main circuit. The number of shortcircuited portions of the rotor winding should be different from the number of brushes and stator poles. The rotor may be provided with two separate windings for the induced and the externallysupplied currents respectively, both windings being short-circuited in the manner described above and only the externally-supplied winding connected to a commutator. The invention is stated to be applicable to generators.

Abstract: 8178. Hollis, E., Rardin, T., and Rardin, J. April 17. Thrashing - machines.-Relates to a machine for removing the ears from standing crops of maize, stripping the outer covering from them, and elevating the husked ears into a wagon. As the machine is drawn along, the rows of corn are guided by slots A between pairs of inclined and divergent rollers 24, 28, which pull off the ears and discharge them on to conveyers 38, 42, 43, which carry them to stripping-rollers 52, whence they pass to an horizontal conveyer 61 and inclined elevator 63. The frame of the machine includes side pieces 7 and a cross-piece 8, and is mounted on wheels 10,11, loose on the fixed axle 9. A shaft 14 is supported by standards and is rotated by means of a crossed chain 16 and a sprocket-wheel connected to the wheel 11. The upper ends of the spindles of the rollers 24, 28 are mounted in bearing-blocks 19, 20 on a cross-piece 18, and the lower ends in projections 27 from the horizontal frame and in brackets carried by a frame projecting from the axle. The chains of the conveyers 38, 42, 43 are driven by sprocket-wheels on the shaft 14, and drive shafts 33, 41 connected with the rollers 24, 28 by bevel - wheels. Boards 44, 45, 46 prevent the ears from falling from the conveyers. The rollers rotate in such a way that the adjacent surfaces of each pair move downwards. The downwardly-inclined stripping-rollers 52 are mounted in pairs in cross-pieces 48, 49, and are separated by partitions 53 with curved faces sloping upwardly towards each other. The elevator 63 passes through an inclined trough 62, and the conveyer 61 lies in an horizontal trough and is driven by bevel-gearing from a shaft 57, which is rotated bv a chain 58 from the shaft 14. The second roller of each pair is driven by contact with the first, the surfaces in contact moving downwards. Motion is transmitted from each pair to the next by bevel-gearing, the outermost roller being driven from the shaft 57. Each roller has a spiral groove 52<1>, the grooves of each pair being arranged to meet at a point which travels from the upper to the lower ends of the rollers.

Patent GB-190511854-A (GB)
Title: Improvements in Weft Replenishing Mechanism for Looms.
Inventor: O'DONNELL FELIX
Filed: 1905-06-06
Granted: 1906-05-31
Abstract: 11,854. O'Donnell, F., and Brown, S. A. June 6. Loom shuttles, changing bobbins and the like in, automatically.-The fresh bobbins or cops are each held at one end by spring fingers mounted upon a circular rotatable feeder 5, and are, at the proper time, forced through the top of the shuttle, displacing the spent cops, which are ejected through a slot in the bottom of the shuttle box. When the weft fails, the weft fork 33<a> is operated in the usual manner by a cam-actuated lever 34, and, through suitable link-work, causes a catch 41 to be withdrawn from a pivoted lever 40, which then drops upon a cam 39 on the crank-shaft. When the lever 40 drops to its lowest position, an upright lever 29, pivoted to the transferrer 25, swings inwards by spring action, and a notch 47 engages a pin 46 on the lever 40. When the lever 40 is raised by the cam, the lever 29 is carried upwards with it, and, through a spring 30, causes a pivoted locking-pawl 31 to engage the teeth of a ratchetwheel 9 upon the feeder, which is thus held in position. At the same time the transferrer 25 is turned on its pivot and depresses a spindle 22, so that a plunger foot 21 on the latter forces a cop 49 out of engagement with its spring fingers 6 and into the shuttle 50. Simultaneously, a set-screw 54 upon the transferrer engages a bent portion 20 of an arm 19 attached to a pawl 14, which, with a similar pawl 13, is pivoted on a bell crank 10, and the pawl 14 is raised out of engagement with the ratchet-wheel 9. Further motion of the transferrer forces the bent portion 20 against the top of the arm 11 of the bell crank, which is thereby turned round the axle 4 of the feeder, and the pawl 13 rides over one tooth of the ratchet-wheel. A U-shaped groove in the arm 12 of the bell crank is, at the same time, freed from a spring bolt 67, which normally holds the bell crank in position. When the lever 40 is lowered again, the lever 29 falls with it, and a helical spring 22<a> surrounding the spindle 22 forces up the transferrer. A cam 64 then depresses a pivoted lever 63, which, through a rod 62, turns a pivoted lever 60. This lever acts upon the bottom edge of the arm 11 to move the bell crank into its normal position, with a setscrew 66 pressing against a stop 55, and the pawl 13 acts upon the ratchet-wheel 9 to turn the feeder, bringing the next cop into position to be transferred to the shuttle. When the transferrer is raised, the pawl 31 is disengaged from the ratchetwheel, and the pawl 14 engages therewith. The vertical lever 29 is acted upon by a cam 51, to cause the notch 47 to be disengaged from the pin 46.

Granted: 1906-09-06
Abstract: 18,671. Bodemer, J. G. Sept. 15. Pulleys and driving-d r u m s.-T h e energy lost in arresting the motion of the rotating parts of mules and the like, such as rope pulleys, rim pulleys, backing-off brakes, guide - pulleys, the supporting-disks of tin rollers &c., which have to be stopped and retarded at the changes, is reduced by reducing the moment of inertia of the parts. This is effected by modifying the construction and by using wrought iron, steel, or a light alloy such as magnolium, in place of cast iron. As applied to a rope pulley, the rims a, b, Fig. 3, are constructed so that the centre lines of the non-central grooves converge towards the pulley axis, thereby reducing the material between the grooves, and such material may be cut away at the inside, as shown in Fig. 6, to effect a further reduction. In addition, the height of the intermediate parts a of the grooves may be reduced, the ropes themselves retaining each other in their respective grooves. The sides of the grooves may be curved.
