Description

UNITED STATES PATENT OFFICE.
. CHARLES F. SPENCER, OF ROCHESTER, NEW YORK.
IMPROVEMENT m LAMP-COLLARS.
Specification forming part of Letters Patent No.*l8l,49l, dated August 2'2, 1876; application filed August 11, 1876.
. the interior, and thus prevent the oil from flowing down over the sides of the lamp-body, which entails waste, besides giving the lamp a dirty and unsightly appearance, and renders it disagreeable to handle; and its object is to cheapen and facilitate the construction of such collars, and atthe same time to provide for more effectually preventing the escape of the oil over the sides and it consists in constructing the collar of a short tube of metal, formed with a depending flange at the top, on its interior, in which is formed the thread for the reception of the lamp-cap, and a broad flange on its bottom, provided with one or more depressions or recesses to serve as oil-channels, the collar thus formed being secured, at the flange, to the interior of the lamp, the tubular part being somewhat smaller than the openingin the lamp-body, andprojecting up through the same, forming an annular chamber therewith,into which the escaping oil flows, as more fully hereinafter set forth.
In the drawing, the letter A represents the lamp-body, constructed of any suitable, material, but preferably of metal; and B, the opening through the same, within which the collar is fitted. C represents the collar, constructed of a short tube of metal, having a horizontal flange, 0, formed within it at its upper edge,
and a depending screw-threaded flange at the edge of the horizontal flange for the reception of the burner-cap. At the lower edge of said collar, on the outside, is formed a broad flange, c, which is provided with one or more depressions or recesses, 0 the object of which will be hereinafter explained. The collar is secured permanently within the opening in the lampbody by securing the flange c to the inside of the same, by soldering or otherwise, in such position that the tubular part of the collar erably constructed in a similar manner.
As thus constructed, the collar may be much more cheaply constructed than hitherto, and applied to the lamp with little trouble or expense.
As the annular chamber will be entirely fastened to and forming part of the oil-fount,
and secured within the lamp in such position that the tubular portion will projectfinto the opening in the same, forming between it and the lamp-top the oil-drip space, substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand in the presence of the subscribing witnesses.
CHAS. F. SPENCER.
