BICYCLE-LANTERN.

' s'rncmxcarro v forming part of Letters Patent No; 533,849, dated February 5,1895. v Application filed August 10, 1894. Serial No. 519,939- (No model.) I

' Be it known that I, WILLIAM L. KEENE, a citizen of the United States, residing at Waterville, inthe county of Kennebec and State of Maine, have invented certain new and use-.

ful Improvements in Bicycle-Lanterns; and I hereby declare the following to be a full, clear, and exact description of the invention,

. such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to a lantern for bicycles and particularly to the construction of a lantern in which is used the parabolic reflector, this formof lantern being recognized as the mosteffective form of head light. I The chief difliculty in adapting the parabolic head light to lanterns of, small size has always been the fact that a cylindrical chimney was used for the lamp on account of the ease with which it could be handled in connection with the reflector and this involved the use of an Argand burner which produced so much heat that the upper part of the lantern was liable to be melted.

In mypresent invention I have adapted the ordinary straight burner with its bulging chimney to a lantern having a parabolic reflector and I have devised simple andeffective means for handling the chimney andremoving it from the lamp without inserting the hand in the reflector. Moreover, in ordinary head lights the chimney is manipulated from inside of the reflector while with small bicycle lanters this cannot be done but the chimney must be handled from outside the reflector.

In my lantern as I prefer to construct it, I run the chimney up through the reflector in the usual manner and I connect the rear end of the reflector with the lamp by means of a hinged connection which allows it to be tilted backward so that the chimney may be 'removed. The forward portion of the reflector is secured to the lamp by a latch which holds it ordinarily in position but allowsit to be re-.

leased and turned backward.

Iillustrate my invention by means of the accompanying drawings, in which- Figure 1 is a sectional view extending from front to rear, and Fig. 2 is apart sectional view at right angles to that of Fig, 1.

A represents the casing or outside of the lantern with its hinged front at which is se-- cured at the bottom by means of a latch j. The front a is provided with a glass bulls eye 5 5 b, which is here shown as made of plain glass.

At the rear of the lantern is a yielding support H of any desired construction by which the lantern is attached to the head of the bicycle. Air is admitted at the bottomof the lantern through an aperture (1 and discharged at the top in the usual manner. The lamp 0 is adapted to be slid into place from the frontof the lanternand it' is provided with an ordinary straight burner e as herein shown and a bulging chimney c of common construction. The chimney cpasses through openings in the parabolic reflector D the lower opening being sufficiently large to allow the largest portion of the chimney to pass. The upper portion of the chimney is supported by a spring f on each side, the lower end of ea ch spring being secured to the reflector.

' The reflector is supported in such a manner that it can be tilted backward for the. purpose 7 5 of removing the chimney. 1 c

As here shown I pivot a link g to the rear end of the reflector the lower end of said link being hinged or pivoted to the back side of the lampin such a manner that it cannot tilt 8o forwardfrom avertical position but it is free to tilt backward.

The forward end of the reflector is secured in its ordinary-0r normal position by means ofa latch h which connects it with the top of the lamp.

Having thus described the construction of my lantern, the operation thereof will be readily understood.

When it is desired to remove the lamp go I chimney for lighting the lamp or for any other purpose, the latch his released and the reentirely removing the chimney.

It will be seen that this construction enables me to make use of a straight burner with its bulging chimney and so avoid the heat which would be generated by an Argand burner.

So far as I am aware no lantern with a para bolic reflector has everbeen in general use for bicycles and it is not necessary to point out the well known efficiency of this class of Ianterns in order to explain the advantages of my invention over others in use. The lantern gives a powerful light which enables the bicycler to ride with nearly as much safety in the darkest night as in the day time.

I claim- 1. The herein described bicycle lantern consisting of a casing, a lamp therein, a chimney for said lamp, a parabolic reflector having apertures through which said chimney passes, a link pivoted to the rear portion of the reflector and to the lamp and a latch connecting the forward end of said reflector with said lamp.

2. The herein described bicycle lantern consisting of a casing, a lamp therein, a chimney for said lamp, a parabolic reflector having apertures through which said chimney passes, a link pivoted to the rear portion of the said reflector by its upper end and to the rear portion of the lamp by its lower end in such a manner that it can tilt backward but not forward and a latch connecting the forward end of said reflector with said lamp.

In Witness whereof I have hereunto set my hand in the presence of two witnesses.

WILLIAM L. KEENE. In presence of- E. F. WEBB,

MARK GALLERT.
