Title: Improvements in or relating to Screw-cutting Machinery
Inventor: PHILLIPS THOMAS ERNEST RAYMOND
Filed: 1902-04-16
Granted: 1903-03-12
Abstract: 8842. Phillips, T. E. R., and Alling- ham, F. A. M. April 16. Screwing; pipe and rod severing machines.-A machine for screwing pipes and rods and cutting them into uniform lengths to form nipples, plugs, junction-pieces, &c., or for tapping nuts, has a rotating hollow mandrel u, mounted on a bed A on which slides a main slide D, operated by rack- and-pinion gearing from a spindle F with a handle H. On the main slide is mounted a supplementary slide J and a removable bracket j carrying an ordinary screwing-head k set by a handle m. The supplementary slide is operated by rack-andpinion gearing from a spindle M with a handle N, and carries an adjustable stop o with flat and coned ends p, r for use with pipes and rods, respectively. A pair of transverse slides T on the slide J are operated by a right and left hand screw S, and carry a second pair of slides W, operated by a right and left hand screw Z, of which the part a is formed on a feathered sleeve to allow the pairs of slides to move independently. The slides W carry cutting, chamfering, or other suitable tools h, and the slides T carry removable jaws f. In screwing and cutting-up a straight length of pipe s, the pipe is gripped in a chuck or revolving head v on the mandrel, the jaws f are removed, and the stop o is set at the required distance from the tools h. The slide J is moved close to the screwing-head k, and the slide D is moved to bring the screwing-dies l of the head into contact with the end of the work. The pipe is then screwed and eventually makes contact with the stop r, holding the slide J stationary as the main slide continues to advance. The tools h on the slides Ware then advanced by turning the screw S to cut off the predetermined length of pipe. During the cutting-off operation, the screwing continues but the slide J remains stationary. The slide J is moved up to the head k after a length has been cut off, and the process continued till the whole length has been cut up. If it is not required to screw the work, the dies are held out of operation, and the slides T reversed, so that the work is steadied between the jaws f while being cut off. For cutting threads on bends, bolts, nipples, &c., the bracket j and screwing-head are removed, and the jaws of the revolving head v replaced by screwing-dies, the work being gripped between the jaws f of the slides T which again face the mandrel. In tapping nuts, the tap is held in the revolving head v. In the formation of double - tapered threaded nipples, tapered dies would be used, the lengths cut off as described and then reversed and held in suitably - shaped jaws. Automatic releasing - mechanism may be provided to prevent collision between the die-head and the chuck v. The chuck or revolving head v is principally of ordinary construction, but the sleeve 6 for opening and closing the jaws or dies is moved by a lever 8 on a spindle 9 having arms 10<a> pivoted to a ring 11 in a groove in the sleeve.

Abstract: 16,928. Lake, H. H., [General Electric Co.]. July 30. Counting - apparatus. - Cut - outs for electric motors automatically break the circuit on overload, and are provided with telltales or counting- devices to register the number of times the circuit has been broken. Figs. 1 and 2 show the invention as applied to a circuitbreaker of known type, in which on an overload an electromagnet 3 operates an armature 4, against the action of a spring 5 having a tensionadjusting rod 6, to engage a shoulder 13<a> formed on a pin 13, Fig. 4, which moves a trip and releases the handle 7 of the cut-out. The counting - device comprises an escapement-wheel mounted on a plate 8 secured by a screw 9 to the circuit-breaker, bearing numbers which appear in succession through an opening in the case, and connected to a spring (not shown), which rotates it when an anchor 15<a> is oscillated by means of a spring 14 adapted to engage the armature 4. A weak spring 19 presses the anchor into its mean position. To enable the cut-out to be actuated without operating the counting-device, a lever 10, provided with a knob 11, is pivoted to the plate 8 so that its forked end 12 engages the end of the trip-releasing pin 13.

Title: Improvements in Alternating-current Dynamo Electric Machines
Filed: 1903-12-19
Granted: 1904-10-20
Abstract: 27,894. British Thomson - Houston Co., [General Electric Co.]. Dec. 19. Motors, alternating- current. - Relates to single - phase s elf - starting alternating- current motors, and more particularly to those of the repulsion type, applicable to elevators and machine tools, having a torque curve similar to that of an induction motor when approaching synchronism, but differing from the latter in that, as the speed falls off, the torque instead of decreasing constantly increases. A further object of the invention is to compensate for the magnetizing-component of the primary current, so that the motor may be operated at unity power factor, or even produce leading currents in the line. The secondary winding B, Fig. 1, is connected to the segments of a commutator C, which is short-circuited by two pairs of brushes d, e, f, g, arranged diametrically so that one pair d, f is displaced by about 20‹ from the line X-Y of the primary field. The starting- torque may be varied by including a variable resistance, inductance, or electromotive force in the short-circuiting connection e, g. The brushes may all be electrically connected together, and three or any other polyphase arrangement of short-circuiting brushes may be employed. The primary member should preferably be similar in construction to that of an induction motor, and be provided with a distributed winding, whereas the secondary member should be constructed like the armature of a direct-current machine. In order to compensate for the magnetizing-component of the primary current, one of the short-circuiting connections is opened, and an electromotive force of proper magnitude and phase, derived from the primary circuit either by means of a transformer or, as shown in Fig. 6, from a few turns a' of the primary winding, symmetrically disposed to the brushes, is introduced, and, when it is desired to reverse the motor by shifting the primary connections from X-Y to X'-Y', the connections of the portion a<1> of the winding to the brushes are also reversed. If any other portion of the winding is utilized, to reverse the motor, the brushes e, g are connected to a different part of the winding having the same relation to the new line of the primary field that the former had to the old line. As the speed of the motor approaches synchronism, the fluctuating field gives way to a revolving field, and the auxiliary electromotive force acts to produce currents in the secondary winding which assist the magnetomotive force of the primary field. In a modified arrangement, all the brushes are placed in electrical communication with one another by connecting the middle point of the segment a<1> to the short-circuiting conductor d, f ; or, as shown in Fig. 9, the brushes f, g and d, e may be joined by independent conductors and the auxiliary electromotive force introduced by way of leads 5, 6, the compensating-current in this case only flowing through the portions b<1>, b<2> of the secondary windings.
