IMPROVEMENT IN LAMPS.

Specification forming part of Letters Patent No. 38,453, dated May 5,1863.

To all whom it may concern.-

Be it known that I, W. H. PrERoE, of Somerville, in the county of Middlesex and State of Massachusetts, have inventeda certain new and useful Improvementin Glass Hand-Lamps; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, like lettersin the figures indicating the same parts, and in which drawings.

Figure 1 is a perspective view of a glass hand-lamp having my improvement represented thereon, and Fig. 2 is a vertical central section thereof.

Glass hand-lamps as heretofore consti ucted having their handles composed of the same vitreous material as the body of the lamp are most liable to become useless by having their handles broken from accidental causes to which they are constantly subjected, particularly in,

packing and transportation.

The object of my invention is to obviate this objection to hand lamps, the bodies of which are composed of glass or other similar ware, and at the same time produce alamp" he prime cost of which will not exceed that of the glass hand lamp in ordinary use. To this end I form the body A of the lamp, of glass, of any desirable configuration, or in the form shown in the figures, and provided with an annular projection, b, as in Fig. 2, around which to secure the screw-collar to the lamp body in the usual way by means of plaster-ofparis. The lamp-body A, as will be seen in the figures,

. is manufactured in the first instance without the glass handle ordinarily attached thereto; but in lieu thereof I supply the lamp with a handle, a, composed of metal and forming a part of the brass or metallic collar D, applied to the top of the lamp. The collar D, Imake of thin plate-metal, which, with the handle 0, may be cut with a die from a metallic sheet and afterward manipulatedinto the form shown in the drawings and there be applied to the lamp-body in the condition of a single connected piece of metal, or the collar D may be formed separate from the metal handle 0, the latter being riveted to the collar by rivets, or by soldering, or in any other appropriate manner, and thereupon united to the lamp-body, as indicated in the figures.

In Fig. 2, 6 indicates the plaster-of paris applied between the annular lip or projection 11 and the collar D to secure the latter in place upon the lamp-body A.

A glass hand-lamp thus constructed is not only capable of being manufactured as a whole as cheap as the ordinary lamp with glass handles, but is far more durable and not liable to be rendered comparatively useless by the accidental breakage of the handle. It is apparent that if the collar D and handle 0 are made in separate pieces and then united as described, the handle 0 may in such case be composed of vulcanized gutta-percha, or a compound of gutta-percha and india-rubber vulcanized, and still answer the purposes of my invention, in which case no unpleasant metallic smell will be imparted to the hand of a person who may carry the lamp.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. Providing the metallic collar of a lamp with a projecting portion or continuation, which shall form the handle of the lamp, sub stantially as set forth.

2. The combination of a glass lamp-body, A, metallic collar D, and handle, 0, substantially as set forth.

3. Fastening a metallic handle to a glass lamp by means of the collar and without puncturing the glass, substantially as set forth.
