LAMP.
SPECIFICATION forming part of Letters Patent No. 281,678, dated July 24, 188 3,
Application filed May 7, 1883.
To all whomit may concern.-
Be it known that I, WILLIAM L. EWING, of
Wheeling, in the county of Ohio and State of West Virginia, have invented certain new and useful Improvements in Lamps 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in that class of pedestal-lamps having oil-intercepting flanges located near the upper ends of their stems, and to an improved process for making them, the object of the invention being to produce simpler and better lamps of this class than have heretofore been made, and to reduce the expense of their fabrication.
With these objects in viewv my invention consists in a lamp consisting of a pedestal formed of a single piece of pressed glass, and having an oil-intercepting flange located near the upper end of its stem, and of a fount which is blown upon and welded to the projecting upper end of said stem.
My invention further consists in a process of making pedestal-lamps having oil-intercepting flanges located near the upper ends of their stems, said process consisting, essentially, in pressing the stem, foot, and flange of the pedestal in one piece, and then blowing the fount upon the projecting upper end of the stem while it is at welding-heat.
In the accompanying drawings, Figure 1 is a view in perspective of a lamp embodying my invention. Fig. 2 is a view partly in elevation and partly in section of a lamp, showing a modification of the process of forming the flange; and Fig. 3 is a view in vertical section through the pedestal of one of my improved lamps and the punty-plate of the mold in which it is formed.
The fabrication of the style of lamps shown in Fig. 1 of the drawings involves the forma tion of the pedestal in an ordinary open-and- .shut mold, the blowing of the fount upon the upper end of the stem of a pedestal so formed while it is still at welding-heat, and, finally, the annealing of the completed lamp.
The pedestal consists of a foot, A, a stem, B. and an oil-intercepting flange, 0, all formed in one piece, the said flange being located just below the upper end of the stem.
(Model.)
The mold in which the pedestal is pressed is adapted to form the oil-intercepting flange, either as a completed flange, as shown in Fig. 5-5 1, or as a ledge, as shown in Fig. 2. In case the latter method is adopted, the ledges are transformed into cup-shaped flanges by means of subsequent manipulation, a buffer in the hands of a skilled operator being the preferred 6o instrument, although a press may be employed, if desired.
One adaptation of a mold to form a completed flange on the stem of a lamp-pedestal is shown in Fig. 30f the drawings. It consists in providing the punty-plate D of the mold with a recess, E, and surrounding the same by an annular shoulder, F. Theproj ecting upper end of the stem is formed in the recess, while the flange is formed by the shoulder surround- 7o ing it. To form a ledge, as shown in Fig. 2 of the drawings, the mold is appropriately recessed.
p The provision of a pedestal-lamp with an oil-intercepting flange adds almost nothing to the cost of the lamp, while greatly enhancing its value. The flange not only intercepts and collects the oil accidentally spilled upon the fount of the lamp, as well as that drawn to the outer surface thereof by capillary attraction, but also enables the lamp to be carried very steadily by the additional bearing upon the hand which it affords. The use of the flange keeps the pedestal clean, and hence prevents the soiling of the hands and furniture. It should also be observed that, owing to the position of the flange, it is prevented from being broken when in use or when packed for transportation. Aside, however, from the value of the flange as a feature of a completed lamp, it plays an important part in its fabrication, in that by increasing the mass of glass near the welding-point of the stem it prolongs the period during which the bowl may be welded to it, and insures a higher percentage of perfect lamps.
I do not claim the punty-plate herein shown and described, but would have it understood that I reserve the right to make the same the subj cot-matter of a separate application.
' I am aware that the stems of lamps having separable founts and feet have been provided with oil-intercepting flanges, and consequently I do not broadly claim such flanges, my invention being limited to a lamp consisting of a ing flange located near the upper end of its pedestal formed in one piece, and having its stem, and of a bowl, the same being blown upsteln provided with an oil-intercepting flange, on the projecting upper end of the said stem and of a fount blown upon and welded to the substantially as set forth. I 5 5 projecting upper end of the stem. I11 testimony whereof I have signed this Having fully described my invention, what specification in the presence of two subscrib- I claim as new, and desire to secure by Letters ing witnesses.
