Ser. No. 446,634 Claims priority, applieation Great Britain, May 13, 1964, 20,005/64 1 Ciaim. (Cl. 29-2519) This invention relates to the threading of wires and the like through apertures and has more special appiication to the threading of the wire or wires of electric loops through the associated cap.
The invention consists in an arrangement for threading wires or the like through an aperture in a member comprising an element for picking up the wire or the like, guide means for bringing the free end of the pick-up element into register with the aperture, means for advancing the pick-up element through the aperture in line with the general direction of the wire or the like to be picked up, means for rotating the pick-up element and Wire with respect to each other to pick up the wire or the like and means for bringing the member and the wire together to pass the wire through the aperture.
The invention will be further described with reference to the accompanying drawings.
FIGURE 1 is a vertical section of the essential parts of apparatus for threading the wire of an electric lamp bulb through a central aperture in a cap for the bulb shown in the starting position.
FIGURE 2 is a similar view in stage one of the threading operation.
FIGURE 3 is a similar view of stage two of the threading operation.
FIGURE 4 is a similar view showing the threading operation completed.
In the drawings a lamp bulb 1 is shown fitted with an axial prong 2 through which projects a wire 3 extending from the filament within the bulb (a further wire would be brought out separately).
The bulb 1 is shown mounted by means not shown with the wire 3 below and located over a cap 4 which is to be fitted over the neck of the bulb and having the usual side prongs 4:1 for engaging a bayonet fitting.
The cap has a central hole or aperture 4b and is held in an aperture 5a in a holding plate 5.
Below the plate 5 is disposed a choker plate 6 having a small central aperture 6a to take the tip of a pick up spiral 7 of spring steel wire vertically disposed and rotated by a base mounting 8.
The choker plate 6 may be raised into contact with plate 5 over the aperture receiving the cap 4 by means of a support member 9 which has a central aperture large enough to take the full diameter of the spiral 7. The choker plate is free to move laterally to accommodate the spiral formation of the wire 7.
The under surface of plate 5 is bevelled around the aperture 5a to aid location of the choker plate 6 and the member 8 may be reciprocated vertically in a cylindrical aperture 5b in the plate 5.
In operation it is required to pick up the wire 3 and guide it through the aperture 41) so that the cap may be positioned on the neck of bulb 1 and the wire soldered in position in the cap 4.
The wire 3 may be bent and misaligned to some extent and provision must be made for this.
The free end of spiral 7 is retained by means of the aperture in the choker plate 6 in an accurately defined position shown in FIGURE 1 so that when the cap 4 is dropped into aperture 5a the free end of spiral 7 engages in the aperture 4b. Once this engagement has been effected the support member 9 may be lowered dropping the choker plate 6 to the position shown'in FIGURE 2 where it may oscillate from side to side as the spiral 7 rotates.
The support 8 for the spiral 7 may then be advanced vertically to pass the rotating spiral 7 up through aperture 41) until it engages the wire 3 as shown in FIGURE 3.
Once wire 3 is engaged the spiral will automatically grip it and straighten it into correct alignment.
The cap 4 may then be raised vertically (or the bulb 1 would be lowered) to the position shown in FIGURE 4 where it engages the neck of bulb 1 and the wire 3 is threaded through the aperture 4b.
Support 8 may then be dropped and support 9 raised again to the positions shown in FIGURE 1 (plate 5 has been omitted from FIGURES 2, 3 and 4 for clarity).
It will be understood that various modifications may be made in accordance with the invention. Thus, it may be arranged to lower the bulb towards the cap before the cap is threaded upwards. In elfect the bulb is lowered so that the ends of the electrodes are down inside the cap a short distance above the bottom of the cap. The object of this is to reduce the length of spiral which can wave about unsupported through the cap before threading.
If two wires have to be threaded simultaneously into the cap 4 then two choker plates 6 may be provided mounted for example on a common support 9 with apertures for the passage of two spirals 7 which might be rotated in opposite directions. Similar provisions may be made for threading three or more wires simultaneously.
Also various other threading operations of wires and the like might be effected in a similar manner using rotatable pick-up spirals.
I claim:
An arrangement for threading wire or the like through an aperture in a member comprising a spiral element for picking up the wire or the like, a member reciprocable along the length of the spiral, having an aperture wide enough to take the wire diameter and free to move laterally in accordance with the spiral formation of the pickup element for bringing the free end of the pick-up element into register with the aperture, means for advancing the pick-up element through the aperture in line with the general direction of the wire or the like to be picked up, means for rotating the pick-up element and wire with respect to each other to pick up the wire or the like and means for bringing the member and the wire together to pass the wire through the aperture.
