Title: Process and apparatus for manufacturing laces having their ends stiffened with celluloid or the like
IPC: A43D98/00
Filed: 1924-05-23
Abstract: 224,471. B³nger, P. May 23, 1924. Laces.-Celluloid or like tips are inserted in position ready for moulding, in tubular woven or braided laces, through slits formed in the wall of the lace. In the machine for doing this shown in Figs 1 and 2, a continuous length of lace g is held under tension, by means not shown, in heated moulds h prior to application of the tips. A slide f is reciprocated vertically to press the lace into an inverted U-bend between guiderollers d, with the outer wall of the lace at the top of the bend impaled on the ends of hollow needles c, the lace being severed by pressing it against a knife edge y by a rubber pad z on the slide. The strips p of celluloid from which the tips are made are fed intermittently forward into grooves t, Fig. 7, formed in rods r which are oscillated to carry the ends of the strips against stationary knife edges v and sever the pieces for the tags. The severed pieces are pressed by reciprocating rammers x from the grooves t through the hollow needles c into the lace ready for moulding in a known manner, the severed ends being pulled by the tensioning means from the needles c on to the moulds h, when the slide f is retracted. Instead of severing the lace when the slits are made in it, it may be severed after the tips have been introduced and when in position for moulding. Alternatively, one needle only may be used to introduce a single tip into the lace, which tip, when moulding, is severed centrally to form two lace tags, or the incision may be formed by a claw which afterwards guides a tip into the incision.

Title: Improvements in and relating to devices for sealing off electric lamp bulbs and the like
IPC: H01J9/40
Filed: 1924-05-26
Abstract: 217,205. British Thomson-Houston Co., Ltd., (Assignees of Martin, C.). June 4, 1923, [Convention date]. Making lamps.-A machine for sealing-off bulbs from exhaust tubes comprises automatic means for moving a fork to pull the bulb away from the tube sufficiently to seal it off and means for subsequently discharging the sealed-off bulb from the fork. In the machine shown in Figs. 1. 2 and 6, which is of the kind described in Specification 14361/06, the exhaust tubes 5 of the bulbs 6 are supported in holders 4 on an intermittently rotating spider 3 adjacent to which the fork 7 is pivotally mounted on a support 9 itself pivoted to a head 10 on a vertically moving rod 13. When a bulb is approaching the sealing-off position, a pin 21 on the preceding holder 4 actuates a lever 22 to depress the head 10 and the fork 7, into the position shown in Fig. 2, against the action of a weight 25 and of a spring 16 mounted beneath a piston 14 in a dash-pot 15. As the burners 26 carried by the head 10 soften the exhaust tube the bulb is pulled upwards away from the tube by the fork 7 under the action of the weight 25 and of the spring 16. After the severance of the exhaust tube a further lift is given to the head 10 by means of compressed air admitted to the cylinder 15 by a pipe 18 and a valve 19 controlled by a cam 20. This causes the tail 8 of the fork 7 to strike a stop 27, the fork thus being tilted into the position shown in Fig. 6 to discharge the sealed-off bulb into a shoot 28. In the modification shown in Fig. 7, all the movements are produced mechanically without the use of compressed air. The fork is initially set against the action of a weight 34 and of a spring 35 by a cam 31. and when a bulb has been sealed off the additional lift is imparted positively to the head 10 by a cam 33.

Abstract: 1,097,014. Cam-operated switches; retractive switches. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. March 26, 1965 [March 26, 1964], No. 12975/64. Heading H2B. A push-button switch has a hollow knob 17 provided with an opposed pair of limbs 18, each having a protruberance 25 resiliently interlocked in an indentation in a slot (23 or 24, Fig. 3) inside a hollow spring-loaded carriage 20 to removably attach knob 17 thereto, carriage 20 being slidable to actuate contact sets. A fixed escutcheon 15 is provided with spring clips 63, 64 to facilitate mounting in a panel aperture. To dismount the switch, knob 17 is first removed by a tool inserted in opposed bores 68, and then another tool is inserted in four ventilatory slots 66, 67. Carriage 20 has pivotally mounted thereon and sliding therewith an arm 53 having at its free end a pin 54 constrained to travel in a heart-shaped fixed stepped cam track 42. Two contact sets 35, 36 are provided, each set comprising two changeover sets each of which has three leaf springs 37, 38, 39. Contact 38 of each set has an arm 71 engageable by a wedge and shaped finger 21 on carriage 20. A tensioned retaining spring 57 mounted on arm 53 has its ends shaped around a third pair of wedges 21. Carriage 20 slides on a tubular fixed lampholder 27, and a lamp illuminates the knob 17 internally, said knob being translucent. A spring 31 urges carriage 20 to the left until bars 33, 34 thereon abut the part 15. In Figs. 1 and 2, knob 17 and carriage 20 are fully retracted. When knob 17 is fully depressed, this movement being limited by a shoulder 69 inside carriage 20 abutting the end of lampholder 27, arms 71 on contacts 38 ride up the slopes of wedges 21 thus causing contacts 38 to change over from contacts 39 to contacts 37. During this depression, pin 54 has travelled from base point A of track 42 to a point D, being constrained to move anticlockwise by a step at point A. As the knob 17 is released it partially retracts and pin 54 travels to point E, and the switch is latched in this position, contacts 38 still making with contacts 37. On the next full depression and immediate release of knob 17, pin 54 travels back to A via points F, G, being constrained to move in this direction by a step at E; knob 17 and carriage 20 return to their fully retracted position, and during this retraction contacts 38 change over from contacts 37 to contacts 39. In a modification, arm 53, spring 57 and track 42 are omitted, and each spring set 35, 36 accommodates a further pair of " make " contact springs on ledge 52.
