Granted: 1904-04-14
Abstract: 12,837. Carolan, E. A., [General Electric Co.]. June 8. Armatures; cool ing and ventilat ing. -Consists in attaining the desired starting- torque in induction motors by connecting the copper conductors, which traverse the magnetic armature core, by means of iron end rings instead of by copper ones as hitherto. The impedance of the secondary circuit is greatest on starting, when there is a rush of current due to slip, owing to the great "skin effect" in iron, and, as the motor speeds up to synchronism, the impedance gradually decreases. In a "squirrel cage armature, Fig. 2, a laminated structure 12 carries the copper conductors 15, which are bolted to iron end rings 16 engaged by supporting-lugs on the core clamping- rings 13. Blades 18 ou the rings 13 create a current of air for cooling the armature.

Title: Improvements in Wire-drawing Machines.
Inventor: HORTON JAMES ALEXANDER
Filed: 1904-11-09
Granted: 1905-11-09
Abstract: 24,260. Horton, J. A. Nov. 9. D r a w i n g.-A machine for drawing wire in the initial or rod stages, and which may be used on the single or multiple pass systems, is. shown in the Figures. Four drums 40<a>, hung on non-rotating studs 41 from a plate 42, are driven by pinions 38, axially-aligned shafts 37, 36, and clutches 44, 45, the lower and splined parts of which are controlled by levers 48 and are weighted so as to fall out of engagement with the upper parts when the torque is diminished due to the wire running out. The shafts 36 are driven slowly by a pinion 49 and wheels 50 connected by single-acting, roller, friction clutches 51 with the shafts 36, three of which carry wheels 58 gearing with three gradually increasing wheels 52, 53, 54 on the shaft 34, and all of which carry a wheel 59 gearing with the largest wheel 55 on the shaft 34. This shaft is driven by bevel gearing from the main shaft 31. The wheel 59 on the one shaft 36 can be connected to the shaft by a friction clutch 60, lever 61, square-ended shaft 62, and a handle 63 so as to drive the corresponding drum at its maximum speed, and either of the wheels 58, 59 on the other three shafts can be similarly connected so as to drive the corresponding drums at the maximum or an intermediate speed, but the simultaneous clutching of both wheels 58, 59 on the same shaft 36 is prevented by vertically sliding plates 65 on the shafts 62. These plates have holes 64 to receive the boss of the handle 63, but the holes are nearer together than the shafts 62 so that handles cannot be put on both shafts at the same time. The drums may thus be run at the same or gradually increasing speeds, and may be fitted with circumferential slipping shoes as described in Specification No. 23,840, A.D. 1903. Each drum 40<a> is slotted at 70 for coil-holding arms 71 which are pivoted to a block 73 and kept in operative position by a rod 80 and links 78. As the coil grows, the arms 71 are depressed, the compression of the spring 76 increasing at about the same rate as the weight of the coil. When the drum is full, a handle 82 and lever 81 are raised and withdraw the links 78, allowing the arms 71 to collapse and the coil to fall on to a reel 100. In Fig. 24, the drum is shown as provided with a dash-pot and with extensions 743 to the links 78 instead of the handle and lever 82, 81. In single-pass drawing, the end of each wire is held in a gripper 87 at the end of a chain 90, which winds into an inclined groove in the drum face and can be retained in the same by a pin when not in use. In multiplepass drawing, the wire is threaded through the die in one of the holders 69 and held by a gripper 87 while being wound a few times around the drum. While this drum is rotating, the handle 98 of a hook 91 is knocked by the attendant to withdraw the prop 96 from behind the hook proper 93, which then releases its grip on the drum. The wire is threaded through the next die and the operation with the chain 90 &c. repeated.

Title: Improvements in Apparatus for Controlling the Supply of Air to Boiler Furnaces and the like.
Filed: 1904-12-03
Granted: 1905-11-09
Abstract: 26,314. Meldrum, J. J., Manfield, W. W., and Meldrum Bros. Dec. 3. Smoke-consuming.-The closing of the furnace door after stoking opens an air-supply valve which gradually closes by its own weight. The cylinder E mounted outside the door A is connected to a bell-crank lever G pivoted to the door at G<1>; the piston-rod is also pivoted to the upper part of the door. The end of the lever G bears against a rod H connected to the valve C, the weight of which holds the cylinder E in the raised position shown by the full lines. Upon the door being opened in the usual way, the lever G swings clear of the rod H and the cylinder falls by its own weight to its lowest position, this being permitted by non-return valves in the piston F. When the door is closed, the valve C is opened and closes gradually on account of the slow return of the liquid in the lower part of the cylinder through the passage M. In a modification, shown in Fig. 5, the cylinder is raised from its normal lowest position, upon the opening of the door, by the inclined plane R. Instead of opening an air valve, the apparatus may be arranged to bring into action a steam-jet blower or similar device.

Title: Improvements in Thread Winding Machines.
Inventor: SAURER ADOLPH
Filed: 1904-12-12
Granted: 1905-12-12
Abstract: 27,099. Saurer, A. Dec. 12. Winding - machines. -Relates to machines for winding cross-wound balls without inner tubes or cores. Means are provided for gradually extending the traverse of the thread-guide, from the centre of the mass to be wound, until a maximum traverse is obtained, after which it remains uniform until the end of the winding operation, and also for gradually decreasing the speed of the traversing guide with regard to the speed of rotation of the spindle. The spindle shaft 1 is driven uniformly, and drives the cam shaft 12, which operates the guide-rod 37, through an expanding pulley 8, 9 and belt 10. The expanding pulley consists of a split spring ring 9, which is supported by pins 18 resting on a sliding cone 17 and passing through apertures in a boss 8 secured to the shaft. One of the pins 18 engages with an aperture in the ring so as to drive it. As the winding proceeds, the cone 17 is moved outwards, so as to diminish the effective diameter of the pulley, by means of a spring lever 14, 15, one end of which engages with the cone and the other with a nut 13 on the screwed end of a shaft 6 driven through worm gearing 3, 4,5 and a clutch from the shaft 1. For the purpose of varying the extent of the traverse, the guide-operating lever 33, 34 is provided with an automatically adjustable fulcrum, as shown in Figs. 1 and 4. The fulcrum pin 31 is carried by a sliding block 30 secured to a rack 28, which is in gear with a toothed segment 26 on a shaft 27 having an arm 25, the end of which engages with a cam-groove 21 in the side of a pulley 19 on the shaft 6. As the shaft 6 and pulley 19 slowly rotate, the end of the arm 25 moves along the eccentric portion 20 of the camgroove, thereby altering the position of the pivot pin 31 until the traverse has been increased to its maximum extent, after which the end of the arm 25 engages with the concentric portion of the slot and the extent of the traverse continues uniform until the winding is completed,
