TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 258,520, dated May 23, 1882.

Application filed March 30,1882. (ModeL) To all trhom it may concern:

Be it known that we, CLARK WooDBUaY, FOSTER W001), and ALLEN J. SAWYER, citizens of the United States, residing at Old Town, in the county of Penobscotand State of Maine, have invented certain new and useful Improvements in Tubular Lanterns; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawingsis a representation of a trout elevation, partly in section, of our invention; and Fig. 2, a side elevation of the same, also partly in section, and broken away to show the manner of swingingthe globe out.

This invention relates to that class of inventions known as tubular lanterns, and the object thereof is to provide a simple, cheap, and easily-operated lantern that may be quickly lighted or extinguished and readily cleaned without removing the globe, thereby rendering the said globe less liable to become broken whenbeing cleaned; also, should the globe become broken when the lantern is in use the burner, being securely fastened to the oil-vessel, cannot fall oft, and thereby ignite the oil, as is often the casein lanterns of this kind. These objects we attain by the construction substantially as shown in the drawings and hereinafter described.

Inthe'accompanying drawings, A represents an oil-vessel of alantern, provided with an airchamber, B, over which is fitted the usual plate, 0, having attached thereto the burner-cap D, which is held securely in place at all times by means of a fiat spring, a, upon the outer side oftheair-chamber engaging with a pin, 1), upon the lower portion of the burner-cap. At the sides of the air-chamber B are connected airtube sections E F, which extend along the top of the oil-vessel and are bent up at their outer ends. To the air-tube section E is suitably hinged a tube, G, and within the upper end of the air-tube section F is seated the lower end of a tube, H. These tubes G H communicate at their upper ends with an upright tube, I, to the lower end of which is suitably hinged the cap K of the globe L. This upright tube I is open at its lower end to admit the entrance of the air which is conveyed to the air-chamber by means of the tubes G H and air-tube sections E F. At the top, where the nprighttubes connect with the tubes G H, is attached the usual bail for carrying or hanging the lantern.

When the lantern is intended to be lighted orextinguished itis taken in the left hand, and a suitable latch, c, which holds the tube H in the air-tube section F, is drawn back with the right, and the weight of the oil-vessel will cause the hinge (1, connecting the tube Gr with the air-tube section E, to open, thereby dropping the burner below the globe, as shown in dotted lines, Fig. 1, thus admitting of the lantern being readily lighted or extinguished without removing any of its parts. Should the lantern be resting upon a table or other support when the latch is released with the right hand, the tubes will be drawn back with the left to theposition also indicated by dotted lines.

The tube H, when unlatched, is prevented from lateral displacement by means of a flat yielding guide-plate, 6, equal in width to and working in the bore of the said tube. This guide-plate is secured at its lower end in the air-tube section F.

The hinge cl, beingof theconstrnctiou shown, will not allow of the oil-vessel dropping farther below the globe than is absolutely necessary to light the wick.

YVhen the globe is to be cleaned the oil-vessel is dropped, as above described, and afastening,f, upon the globe-cap K is .turned so as to allow it to pass through a slot, g, in the plate 71. upon the lower end of the upright tube I, and thus admit of the globe-cap K, to which is attached by any suitable means the globe L, being swung out, as shown in Fig. 2. By swinging the globe out, as above described, the said globe may be readily cleaned without removing the same from the lantern-frame, thus preventing the globe from becoming broken by being dropped from the hands while in the act ofcleaning, as is frequently the case where the said globe is entirely removed from the lantern-frame.

The burner is readily removed for the purpose of inserting a new wick by releasing the flat spring-catch a from the pin 1) upon the burner-cap D when the oil-vessel is dropped down below the globe and lit'tin g the said burner out from its position in the air-chamber B.

Having now fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is-- 1. In a tubular lantern, the combination, with the tube Gr, hinged at its lower end to the stationary tube-section E, of the tube H and stationary tube-section F, the latter being provided with a fastening device for securely locking the tube H to the tube-section F or releasing it therefrom, substantially as andt'or the purpose set forth.

2. lnatubnlarlantern, the combination, with the upright tube I, of the cap K, hinged thereto and carrying the globe L, substantially as and for the purpose specified.

3. In a tubular lantern, the hinged tube G and tube H, in combination with the air-tube sectionsEEthelatter havinga yielding guideplate, 0, and suitable means for fastening or releasing the tube H therefrom, substantially as specified.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
