SPECIFICATION forming part of Letters Patent No. 284,616, dated September 11, 1883.
Application tiled December 14, 1882. (Model.)
To all whom it may concern..-
Be it known that I, JOHN W. COOPER, a citizen of the ,United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and use ful Improvement in Lamp-Tops; and I do 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, reference being had to the accompanying drawing, which forms a part of this specification.
My invention relates to lamp-tops for kerosene or other oil lamps where the body of the lamp or the vessel which contains the oil is made of glass, porcelain, pottery, or other similar material.
Its object is to enable the said top to be securely fastened to the lamp without the use of plaster-ofparis or cement, and in such a manner that the joint will not permit the leaking through of oil or the gas from the same; and it consists of the combination of the following elements, viz: a tube, of brass or other soft metal, which is inserted into the neck of the lamp and turned down at its upper portion, so as to form a collar covering` and inclosing the said neck, having on its outer surface a screwthread, and securely fastened to the lamp by being spun against the lupper portion of the interior surface thereof adjoining the neck, a washer placed around the neck of the lamp, under the lower edge of said collar, and aring or cap, of brass or other soft metal, which is screwed onto said collar and down upon said washer.
In the accompanying drawing, A is a plain or smooth tube, made of brass or other suitable metal, of such size as to be easily inserted into the neck of the lamp, and far enough to have its lower end or portion, A', project into the lamp. The tube fits snugly against the inner face of the neck, and the lower extension, A, is bent, pressed, or spun outward against the inner surface of the body of the lamp, as shown. The outer end of the tubeA is first bent outward, so as to provide a horizontal seat, A, which covers the top of the vertical neck B. It is then bent vertically downward, so as to form the depending rim C, surrounding the neck. The dependingrim C is provided with a thread adapted to receive the threaded extended rim of the cap E. The end of the depending rim C rests on the body of the lamp on an interposed washer, D.
D is a washer of suitable material, preferably of gelatine so treated as to be unaffected by water or the hydrocarbon or other oils, which is placed around the neck of the lamp, and upon which the lower edge of the collar B bears.
E is a cylindrical cap somewhat in the form of a truncated cone. It has the extended ring or portion E, which is threaded and adapted to be turned down on the thread of and over the rim C and down against the lamp or onto the interposed washer D, thus securingatight and impervious joint. The lower part of the cap E may be provided with aange the edge of which is turned down slightly less than the thickness of the'washer, as shown at g, thus inclosing and covering the washer when the cap E is screwed down and rests upon the same. The cap E is composed of the external ring, E', hereinbefore described, and the internal tubular portion, E?. The internal tubular portion, E2, is provided with a thread adapted to receive the threaded shank of the burner, and it is made of about the same diameter as the smooth tube A. It will be seen that the external ring, E', projects above the top plate, A2, of the inner tube, A, and that the lower Vend of inner ring, E2, rests on the top of said plate A2.
The thread for holding the burner may be cut in the upper part of the tube A, instead of in the upper part of the cap E, as herein described, in which case the inner ring, E2, would be in the form of a broad ring.
The within-described device mayalso be applied to the opening where the'lamp is filleda construction common to many kerosenef lamps-in which case the cap E will be closed at the top. It may also be applied to any glass or `earthenw'are vessel-such as fruit or preserve jars-where an air-tight top or cover is need ed, in which case an ordinary washer of indiarubber or other suitable material would be used.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
. l. The combination, with the lamp having IOO a vertical neck, B, of a smooth tube, A, placed in the neck B, and having its lower inner portion spun or pressed outward against the interior `surface of the upper portion of the lamp, and having its outer portion or end, A2, provided with a thread or screw, A3, bent over the top and down along the outer side of the neck B, and supported on the body of the lamp or upon an interposed Washer, substantially as set forth.
2. The combination, with the lamp having a neck, B, of the inner tube, A, having its outer end provided with a horizontal portion, A, and a threaded portion, A, covering and surrounding the neck, the cap E, having the exterior threaded portion, E', adapted to fit on the threaded portion A3, and the internal depending tubular portion, E2, threaded to receive the shank of the burner, and resting on the horizontal portion of the tube A, and a Washer interposed between the body of the lamp and the lower ends of the portions A3 and E', substantially as set forth.
3. In a lamp-top, the combination of the tube A, Washer D, and cap E, substantially as and for the purpose herein described.
4. In a lamp-top, a gelatine Washer, in co1n bination with a screw cap or ring bearing upon the saine, and a tube with collar covering the neck of thelamp, and secured to said lamp by being spun or pressed against the interior surface thereof, substantially as and for the purpose herein described.
