Tu be, of which the following is a specihestion.
This invention relates to electric light bulbs, more particularly to bulbs of the soczlled miniature type which are generally formed from; tubular glass.
in the manufacture of bulbs of this class "tubing is generally used, the tubing irst cut into units of proper length. il ler heads are then blown, or molded e units, said heads tapering down to .oulur neck, the neck retaining sutlicient to admitof the sealing therein, in proper position, of the filament stern. The bul s as an article of manufacture are thus formed of predetermined uniform dimensions. and the stems are afterward sesle "ein by a separate operation.
heretofore in the manufacture of bulbs ,iu' LT 1 }Q oi ems type, the ,llObll ar heat ias seen foried from the tubing unit while theoriginul diumetricul dimension, and thickness of material of the tube has been muinl in the neck. This uniform thickmaterial makes it difficult to form his seal between the neck and the tilement stein. I
Tue object of the present invention is to provide bulbs of this character that can be iorcexpeditiously and reliably sealed than i the bulls as heretofore manufacture. 3h object is attained by the peculiar formu- -i of the bulb. Which facilitates the rereeling, or attachment of the neck: to the stem which carries the light 1, will be hereinafter fully desmibed end definitely pointed out in the claims, reference being bad to the accompanying drawings which are made part of specificetio- ,siruilsr referencecharacters being employed to designate corresponding u nts.
drawings Figure 1 is an elevaion of the improved bulb. Fig. 2 is s cenverticul section. Fig. 3 is an illus- 7 rs ion of s filament stem detached. Fig. 4 illustrates the impgoved bulb, partially in 'ection, showing the filament stein in elevation of esealed bulb.
The present invention provides, as a new article of manufacture, t bulb having a globular element 1 formed from the tubing, 6
said globular element tapering down to the throat line 1 Where the full thiclmess of the material is maintained. The tubular well of the neck is drawn down from the throat line l to comparative thinness at andfiB slightly below the sealing line l This peculiar formation of the neck provides thickness of material at the throat Where it is desirable for strength, while the glass beinc, thinner at the sealing line facilitates the reliable sealing of the filament stem 2 in the neck of the bulb, and the detaching of the sunerfiuous portion 1 of the tube, after the seal is made.
What We claim and desire to secure by '95 Letters Patent is.
1. As a new article of manufacture, an electric light bulb, comprising an inclosed head, and ii tubular neck, the Wall of said neck being drawn down from a predetermined thickness at the throat line to comparative thinness at the sealing line.
2. As an article of manui'acture, an elecv trio light bulb, comprising a globular head,
and tubular neck. the Wall of said neck being a predetermined thickness at the throat and drawn down comparatively thin in proximity to the sealing line. i
3. An electric light bulb having a globular head and a tubular neck Within which, the filament stem is to be sealed, the Wall of the neck being reduced in thickness from the head to the sealing line and increased in thickness from said sealing line to the lower terminal of the neck.
in testimony whereof We afix our signs sures.
