MANUFACTURE OF BULLS-EYE LANTERNS.

' SPECIFIQATION forming part of Letters Patent N0. 507,849, dated October 31, 1893. Application filed April 24, 1893. Serial No. 471,578. (No specimens.)

To all whom it may concern:

Be it known that we, ANDREW D. SEAMON and AMOS WILSON, of Martins Ferry, in the countyof Belmont and State of Ohio, have invented a new and useful Improvement in the Manufacture of Bulls-Eye Lanterns, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical sectional view of the mold, and Fig. 2 is an elevation of the globe showing the bulls-eye in section.

In the drawings, 2 represents a lantern globe-mold of the ordinary form and construction, in the interior bilge of which,l10wever, is an annular groove or recess 3, within which the mold has a flat annular face 4.

In the manufacture of our improved globes, we place an annular metallic ring 5 in the groove 3, so that the edge of the ring shall project slightly from the recess. We then blow the globe in the mold in the usual manner and the glass inclosing the projecting edge of the ring. The ring is firmly secured in the side of the globe, and the outer face of the globe within the ring is formed with a smooth fiat annular portion 6.

The glass bulls-eye or lens 7, which is of the same diameter as the interior of the ring, is formed as aseparate piece by being pressed, and may be ground or polished, and is then inserted in the ring 5, which projects from the outer face of the globe, and the edges of the ring are turned down over the edges of the bnlls-eye so as to retain the fiat face of the same against the flat face of the globe within the ring. Instead of turning down the edges of the ring over the edges of the bulls-eye,

the ring may be provided with a female thread 40 adapted to engage with the edge of the bullseye.

The advantages of our invention will be apparent to those skilled in the art. By forming the bullseye separately from the globe or chimney, it is capable of being ground and polished, and in case of the globe or chimney being broken, the bulls-eye may be removed and placed in another globe.

What we claim,and desire to secure by Let- 5 ters Patent, is

1. The herein-described method of forming bulls-eye globes or chimneys, consisting in blowing the globe about a portion of a metallic ring in the mold; forming the bulls-eye separately from the globe, and securing the bulls-eye within the projecting portion of the ring; substantially as described.

2. The herein-described method of forming bulls-eye globes or chimneys, consisting in blowing the globe about a portion of a metallic ring in the mold; pressing the bulls-eye separately from the globe, polishing the bullseye; and securing the bulls-eye within the projecting portion of the ring on the outer face of the globe; substantially as described.

3. A mold for bulls-eye globes and chimneys, having an annular recess 3, arranged to receive a ring and a flat portion 4. on its inner face within the recess; substantially as
