Patent GB-190227815-A (GB)
Title: Improvements in Apparatus for Use in the Manufacture of Tubing
Filed: 1902-12-16
Granted: 1903-07-09
Abstract: 27,815. Lake, H. H., [National Tube Co.]. Dec. 16. Bending; drawing; welding.-In the manufacture of butt-welded tubes by drawing heated skelps through a welding-bell, the drawing-chain is provided with means for automatically increasing its speed after the skelp has entered the bell, thus allowing a faster speed to be used in drawing than can be safely used in connecting the draw-hook to the chain, starting the skelp, and introducing it into the bell. The increased speed allows a skelp of double the standard length to be drawn and welded at one heat. Preferably the driving- mechanism comprises an electromotor provided with a generator and booster system, indicated diagrammatically in Fig. 2. The motor 14 is connected to the mains 16, 17 of a generator 15, and preferably has shunt and series field windings 19, 20 and is provided with a suitable starting- switch 21, which brings the field of the winding 19 to its full strength before gradually increasing the current in the armature 18. The winding 19 has a variable resistance 38 so that the strength of the field may be varied to vary the speed of the motor. The motor armature 29 and generator armature 32 of the booster are mounted on a common shaft 28. The booster motor has a shunt field 30 and a starting-switch 31. The booster generator has differential field windings 33, 34, the former of large current-carrying capacity and in series with the generator armature and with the winding 20 while the latter is a fine wire shunt winding. Each winding has a variable resistance 36, 37. When the motor 14 is running at its desired lower speed, the resistances 36, 37 are adjusted so that the windings 33, 34 produce a field of zero strength, the booster generator producing no current. When increased load is thrown on the motor by the entry of the skelp into the bell, an increased current flows through the motor armature and through the winding 33. The booster generator then generates current, which flows through the winding 20 and thus increases the torque and speed of the motor armature. When the load is thrown off, the motor resumes its lower speed. Variations in details of the electrical system may be made.

Title: Improvements in Speed Gears specially applicable for Motor Cycles and Motor Cars.
Inventor: HASTE FREDERICK CHARLES
Filed: 1904-05-09
Granted: 1905-04-20
Abstract: 10,684. Haste, F. C. May 9. Driving-mechanism ; clutches.-A speed-reducing and gradual-clutch gear is mounted on the back axle of a motor cycle &c. in connection with a chauge-speed gearing in the hub. To the looselymounted driving wheel or pulley 1 is fixed the sun-wheel 2 of an epicyclic train in which the outer annular wheel 8 is attached to a brake-wheel 9 mounted loosely on the axle 7, while planetwheels 5 are supported by a carrier 3, to which is rigidly connected a drive-plate 10, also looselymounted on the axle. When the brake-wheel 9. is free, the drive-plate 10 will not be driven, but, by gradual application of the brake, the plate 10 is rotated and the speed is gradually increased until the brake-wheel is held stationary. The driveplate 10, from which is driven the change-speed gear, is provided with four holes 11, in which are received pins 12 on a toothed eccentric wheel 13, gearing into the annular wheel 14, fixed in the hub 15. An eccentric 16 is mounted loosely on the axle 7, working in the ring 13, and is clutched either to the hub or axle, giving, in the former case, the same speed as the drive-plate 10, and, in the latter case, a reduced speed. To clutch the eccentric 16 to the hub, a sleeve 40 is provided with teeth 41 engaging with teeth on the boss of the eccentric 16, and with teeth 43 which always engage with teeth 44 on the hub 15. It is drawn out of engagement by the wire 46 acting on a cross-bar 47, and, when released, is forced by the spring 45 into engagement again. An automatic catch, to prevent backward movement of the eccentric 16 at the lower speed, consists of a ring 50, free to slide and rotate, with ratchet-teeth at each end adapted to engage with teeth 51 formed on the end of a stop-piece 53 fixed to the axle, and teeth 52 formed in the end of the eccentric 16 of double the pitch of the teeth 51. In a modification, the eccentric spur wheel and gear are replaced by a second epicyclic gear, the studs for the planet-wheels being fixed in the hub, backward rotation of the sun-wheel at the low speed being prevented by an automatic catch as in the above case.
