UNITED STATES PATENT, OFFICE.
CHARLES E. WHALIN, OF SALT LAKE CITY, UTAH, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO WHALIN AUTO LENS & LIGHT 00., A CORPORATION OF UTAH.
LANTERN GLOBE.
Application filed March 21, 1923. Serial No. 626,558.
To all 107mm it may concern:
Be it known that I, CHARLES EnlVHALIN,
a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Lantern Globes, of which the following is a specification.
My invention relates to lanterns, and has for its object to provide a globe for an electriclantern which is made of a plurality of plano-convex lenses integral at their edges with the contiguous lenses and preferably with the convex surfaces meeting'in regular curves to give the globe a spherical shape, except on one face Where the glass is ex tended and externally threaded for fasten ing the globe in the lantern.
These objects I accomplish with the device illustrated in the accompanying drawings in which similar letters and numerals indicate like parts throughout the several views and described in the specification forming a part of this application and pointed out in the appended claim.
In the drawings in which I have shown a substantial embodiment of my invention,
Figure 1 is an elevation of an electric lantern with one of my globes 111 place thereon. Figure 2 is tSlClQ' elevation of the globe in detail with some of the plane surfaces shown in dotted lines. Figure 3 is a section of the globe on line 33 of Figure 2. Figure 4 is a section on line -ls of Figure 2.
I have shown and I use a common form of electric lantern A having a bail B, a battery container 0 and a base frame I), which base frame is made of small wires to support the lantern and yet obstruct the rays of light as little as may be while they support the lantern and protect the globe from being broken. in electric bulb E is screwed into tl e bottom of the battery container 0 and the commonly used switch is mounted in the side ofsaid container C to open and close the electric circuit of said bulb E, as
desired. In the bottom of the said battery container I provide an internally threaded socket within which is screwed the neck of the globe G. The said globe G is made of lens glass and consists of a plurality of plano-convex'lenses, the lower one preferably positioned parallel with the base D of the lantern. In the globe shown in the drawings I have illustrated a globe having a cubiform interior, but other shaped interiors, such as a dodecahedral or an octagonal form may be used, thereby increasing the number of lenses and multiplying the focal points. With the cubiform interior I provide five lano-convex lenses, one at the one central bulb E. By increasing the number of plane surfaces on the interior of the globe G the number of focal points will be increased, should that be desired, and the number of bulls eyes multiplied.
Having thus described my invention I de-' sire to secure by Letters Patent and claim A lantern comprising a frame in which a globeis mounted and an electric light bulb as its source of illumination; said globe fastened in the bottom of said frame and surrounding said electric light bulb in spaced relation thereto, said globe consisting of live plano convex integral lenses one forming thelgiettom of said globe and the other four the sides of said globe integrally formed as a sphere except at the side nearest the frame, which side is extended and externally threaded for engagement with said frame.
In testimony whereof I have afiixed my signature.
CHARLES E. WHALIN.
