ROLL FOR FLATTENING THE ENDS 0F TERMINAL WIRES.
SPECIFICATION 'forming part of Letters Patent Nb. 276,982, dated May 1, less. Application filed July 2 0;1882. No model.) Patented in England June 19,- 1882, No. 2,898.
To all whom it may concern; Be it known that I, ALFRED SWAN, a subject of. the Queen of Great Britain, and residing at Gateshead, inthe county-of Durham,
- England, have invented certain improvements in apparatus for flattening out the ends of the terminal wires forincandescent electric lamps preparatory to forming them into tubular o'r spiral form for the reception of the carbon lilament, (for which I have "obtained a patent in Great Britain, No. 2,898, dated the 19th day ofJune,1882,) of which the following is a specification. 4
My'inventiou relates to improvements in apparatus for flattening out the endsof the terminal wires of incandescent electric lamps preparatory to forming them into a socket for the reception of the carbon filament. Iefl'ect this flattening preferably after the wire has been embedded in theglass of the stem, when, if they said wire terminates in a U form, as in Figure 3, Isever it at the center of the bend,
as in Fig. 4, and I straighten out the severed parts and thenflatten them out ina press constructed as illustrated in the accompanying drawings, of which- Fig. 1 is a front view, and Fig.2 is a transverse section;
The cam-like rollers p p are mounted in a framing, p, and are geared together by toothed gearing at 19 and one of them is provided with a handle,p for turning the rollers.
The opposedpressing-facesof the said cam-rollers p p are cut away, to allow of the introduction to their full extent and thickness of the portions of wire projecting beyond the sten ot' glass or the like. The said camrollers p p, owing to their shape at the parts y a extending from the point at which-they begin to act upon the wire, (the position shown to thin. The main pressing-surfaces of the" rolls are concentric with their axes, so that flattened portions of the same width and thick- ,ness throughout, except at the junction with the unflattened portion, where there is, as stated, a gradual taper from the flattened to they will flatten the wire equally, leaving the V the unflattened portion. The ends of the dart toned-out blades (enlarged views of which are shown in Fig. 5) are then cutoff, by means of a cutting-press of any convenient form, to an angle, which determines or is determined by the pitch of the spiral to be produced.
Fig. 6 represents a stem with the ends ofthe terminal wires flattened out and cut, as hereinhefore described.
Iclaim as my in ven-tion-- The described rolls for flattening the terminal wires in incandescent electric lamps,
having their pressing-surfaces mainly concentrio with the respective axes thereoflbut eccentric at the points which act first upon the wire, so as to make a gradual passage from the round to the flat portion, and having also the larger part of one side cut away, substantially as described.
In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. I
, ALFRED SWAN. Witnesses: RoB'r. SPENGE WATSON, Solicitor, Newcas'tZeon-Tyne.
