LANTERN.v

srncrrroArIoN forming part of Letters Patent No. 529,78 7, amen November 27,1894.

Application filed April 15, 1893. Serial No. 470,451. (No model.)

To all whom it may colwern:

Be it known that I, WILLIAM S. HAMM, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Lanterns, of which the following is a specification.

My invention is intended more particularly for railway lanterns but is applicable to Io others.

The object of my invention is to raise and lower the wick without removing the lamp from its place in the lantern. To this end I apply to the lamp a ring concentric with the burner and adapted to engage the wiek-wheel by which the wick is ordinarily raised and lowered. The ring and wiek-wheel may be toothed, or otherwise adapted to engage,'the

essential being that the rotation of the wickp wheel shall be determined by the rotation of said ring. This ring I connect withasecond ring conveniently located on'the lamp. The connection is made preferably by rods which embrace the lamp and hold the two rings in place.` I also use a thumb-Wheel attached either to the lamp or to the body of the lantern and adapted directly or indirectly to act upon the second ring abovementioned, rotate it, and through it the first ring thereby acting upon the wiek.

In the drawings: Fgure lis a partial vertical section, and Fig. 2 is a plan diagram showing the upper part of the lamp and Vthe devices for acting on the wick.

1 is the body of the lantern while I have omitted the usual cage and cap of the lantern for simplicitfs sake.

2 is the globe.

3 is the lamp.

4 is the burner.

5 is the usual wiek-wheel, and 6 the stem by which, ordinarily, the wick is raised and lowered.

7 is a ring preferably concentric with the burner and adapted to engage the wiek-wheel 5 either by means of teeth or otherwise so that it will rotate the latter.

8 are rods, preferably of spring metal, supporting the ring 7, extending down the side of the lamp and engaging a groove 9 in the 5a 'with the ring 10 as that the latter will leave it when the lamp is taken out of the lantern and will engage it again when-the lamp is put back.

The rods 8 may be made to embrace the lamp with sufficient friction to prevent any acoidental disturbance of the wiek from jarring or swinging of the lantern or other cause.

I hereby disclaim, as a part of my present invention, thev construction set .forth and claimed in my application Serial No. 470,452, filed of even date herewith, in which a horizontal hand ring outside the lantern is connected with an interior horizontal toothed ring engaging the gear of the wiek raising stem.

The combination, with a lantern and lamp, of a lower gear ring connected t o the lamp, an upper gear ring adapted to engage a toothed wick wheel, rods connecting the two gear rings, and a thumb wheel outside the lantern and provided with a stem and a toothed wheel 8 5 inside the body of the lantern, said wheel engagingthe lower gear ring in such manner as to allow detachment therefrom when the lamp is taken out of the lantern, substantially as set forth.

WILLIAM S. HAMM.
