Title: Improvements in Apparatus for Winding or Producing Coils, Bobbins, Helices, or the like, for Electrical and other Purposes.
Inventor: HEYS WILLIAM GEORGE
Filed: 1900-03-20
Granted: 1900-08-04
Abstract: 5257. Heys, W. G., [Scott, J., Varley, R., and Anderson, J. C.]. March 20. Wire.-Relates to apparatus for winding or producing coils, bobbins, helices, &c. for electrical and other purposes. The machine described is specially for winding side by side and simultaneously a naked wire and an insulating - thread, and wrapping upon each coil as it is completed a sheet of paper or other insulating-material, the parts of each coil being insulated from one another by the thread, while the several coils are insulated from one another by the paper sheets. Five or any other number of pairs of strands are passed over guides 84, 85 and wound into a corresponding number of coils on a reciprocating spindle 13 provided with a presser roller 206. Paper of a suitable width for all the coils is drawn from a reel, passed over a table 137 having a reciprocating presser roller 141, beneath a knife blade 136, and over a spring table and beneath a reciprocating roller 167, by which the severed strip of paper is injected into the nip of the winding-spindle and roller 206. The rollers 167 and 141 are covered with rubber, and are provided with ratchet gearing by which their rotation is prevented during the operation of feeding forward the strip of paper. The cutting and feeding mechanism are carried by a slide 119, which is mounted upon a second slide 99. The slide 99 is reciprocated uniformly towards and from the winding-spindle, and during its rearward movement draws with it by means of a pair of hooks 105, 150 the upper or feeding carriage 119. Means are provided whereby the slides 119 and 99 are disengaged at a slightly later period at the completion of each second coil, so that the length of paper severed from the strip is made gradually longer as the diameter of the coil increases. The knife blade 136 is depressed to make the cut when the slide 119 is in its most backward position. The edge of the knife inclines downwards from each side towards the middle, where it terminates in a sharp point. The slide 99 and other mechanism are carried by a pivoted carriage 58, which, as the coils increase in diameter, is tilted, so that the strips of paper may be properly projected into the nip of the roller 206 and the coils being wound. Mechanism is described for properly operating and adjusting the several parts of the machine.
Patent GB-190005850-A (GB)
Title: Improvements in Fare Boxes for Tram Conductors and the like.
Inventor: GLEDHILL GEORGE HENRY
Filed: 1900-03-29
Granted: 1901-03-16
Abstract: 5850. Gledhill, G. H., and Gledhill, A. H. March 29. Fares, collecting. - A penny or two halfpennies are inserted into a box at a slot 1, and are thrust past one of the levers of a crescent-shaped trap 3 on a pivot 4. They then fall into one of the pockets of a star - wheel 5, which turns behind glass with a ratchet pinion 7 when a lever 9 bearing a pawl 8 is operated by an external lever (not shown) on the fulcrum 10. Once in a revolution a hinged trap 22 is operated by a cam to let the fare in one of the pockets drop into a locked receptacle 23, while the fares from all the other pockets drop out beyond the trap into a receptacle 26 to which the conductor of the car has access for change. If silver coins are inserted by mistake, they also drop into the locked receptacle 23 through a gap 25 in the guard ring. The ratchet-wheel 7 operates the hammer 32 of a gong, and a gear-wheel drives a counter which is shifted out of gear when the door of the receptacle is opened to overhaul the takings. The movements of the ratchet lever are limited by stops 44, and their completion is ensured by means of a toothed sector 39 under a reversible pawl 40. The pressure of the entering coin upon the crescentshaped trap 3 frees it from a spring finger 21, and allows it to be turned behind the coin by means of a spring 20 pulling a link 17. A bevelled lug 18 on the link gets above a bevelled shoulder 19 on the frame, and the bottom of the link having a slot 16 travels over the pin 48 of a crank 15 on the fulcrum of the ratchet lever. The coin entrance is thus blocked till the ratchet lever is operated, and the crank consequently drags the link down again. A pivoted pawl 47 under the crank-pin arrests it if operated without the previous insertion of a coin, but a pin 49 on the link disengages the pawl. The coin entrance, Fig. 10, is contracted centrally or at one end, so as to prevent two pennies from being inserted side by side, but to allow two halfpennies.

Relates to improvements in the machines described in Specifications No. 15,046, A.D. 1896, and No. 9999, A.D. 1897. The driving- shaft 2 is geared to a spur-wheel which is mounted on a shaft 4 carrying an eccentric 5. By means of this eccentric the jack-frame 12 is rocked about the spindle 52. The toe and heel posts are mounted on an arm 14, which is pivoted to the frame 12 and at times is locked to it by the following means :- When the treadle 18 is depressed to bring the levelling-rollers into use, the cam 53 is rotated to operate a bell crank 63 actuating a locking-bolt. When the treadle is raised, the bolt is withdrawn. The shank-roll 24 and fore-part roll 23 are mounted in yokes as described in the previous Specifications, and are reciprocated by an eccentric on the shaft 2 acting through a rod 28 and bell crank 25. The means described below are employed to raise the shank-roller at certain positions of the shoe. A cam 38 is rocked by the jack frame, and by means of a bell crank 34 raises and lowers the yoke 22. The position of the cam can be adjusted by worm gearing. The shank-roller is made in halves, as shown in Fig. 6, and the inclination of the halves can be varied in the manner shown in dotted lines. They are mounted on studs carried by curved slotted plates which can be adjusted by worm gear and locked by bolts and thumb-nuts. In a modification, the roller is mounted so that its axis can swing in a horizontal plane to assume the positions indicated by the dotted lines in Fig. 14. As shown in Fig. 13, the plate 91, by which the half-rollers are carried, is pivoted on a pin 92 mounted in a bracket which can swing about a vertical pin 88.
