ATTACHMENT FOR LANTERNS.

Specification of Letters Patent.

Application filed March 21, 1908.

Patented Feb. 2, 1909.

Serial No. 422,606.

To all who 1., tt may concern:

Be it known that I, ORVA A. WILLETT, citizen of the United States, residing at Wellington, in the county of Sumner and State of Kansas, have invented certain new and useful Improvements in Attachments for Lanterns, of which the following is a specification.

This invention contemplates certain new and useful in'iprovements in lanterns, and the object of the invention is an improved lantern attachment which is designed to be operated by the user to cause the lantern to emit a colored light when desired, and which is thus particularly adapted for signaling purposes or the like, since the signalman can use the same lantern to display a colored or 1 white light, according as required.

With this and other objects in view, that will more fully appear-as the description 'proceeds,the invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe and then point out the novel features thereof in the appended claims.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction,

reference is to be had to the following description and which:

Figure 1 is a side elevation with parts in section, of a lantern showing my improved signaling attachment applied thereto; Fig.2 is a detail view in section, showing the shade in raised position; and, Fig. 3 is a similar View in perspective, of the holder and the accompanying drawing, in

' adjusting rod.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawing, by the same reference characters.

This invention is designed to be applied to a lantern A, which may be of any desired construction or design, exccptthat it em bodies a preferably colorless chimney B and a crown plate C secured across the upper end thereof, said crown plate being formed with an aperture D extending therethrough.

My improved lantern attachment embodies a preferably cylindrical efrtensible tube that is constructed in telescopic sections. one ofsa id sections 1 being relatively stationary and constructed ,of any suitable opaque substance. This section 1 is formed at its upper end with an outstanding flange than the section 1, and is about the same length as the latter, said section being arranged to ext end around the flame when the tube extended, and being constructed of a translucent substance, so as to form a shade 3 adapted to intercept the rays of light and modify the same in color. The shade 3 isprovided at its upper end with 2! preferably metallic collar 4.,- and its lower end rests against an annular holder 5, and fits in a cupped rim 6 formed at the upper edge of the letter, said holder resting against the body portion of the lantern, when the tube is in extended position, and being formed with notches 7 extending therethrough to admit air to the burner.

A spring, adjusting rod 8 is secured at its" lower end to the holder 5, and extends u wardly therefrom through the aperture 5 1n the crown plategsaid rod being formed near its upperend and near its middle with crinips i) and 9 respectively. This rod bears against the outer wall of the aperture 1), and the crimp 9 at the up er and of the rod is arranged to be pushe downwardly through the ap rture D of the crown plate, when the shade is lowered into an operative'position, and is adapted to bear against the crown plate to prevent the rod from sliding; through the aperture therein, to permit the shade to accidentally return to an inoperative position during the swinging of the lantern. The intermediate crimp 9 of the rod is arranged to he passed upwardly through the aperture I), when the shade is raised to an inoperative position and the tube tclcscoped, and is designed to abut against the crown plate, to suspend the shade securely in such raised position.

It will be noted that the upper or relatively stationary scctirm 1 of the tube, will protect the chimney 1-3 of the lantern from smoke and heat, when my improved attachment is not in use. i

It is to be understood that theiadj usting rod 8 may extend through the'lowerend of the lantern, in case it is more convenient to operate the shade ffom the bottom.

From the above description. in connection with theaccompapying drawing, it will be ap mrcnt that I have provided a simple, du-

rahle and ethcient lantern attachment which may be readily operated to positively con trol the color of the light emitted from the lantern. which may he applied to all lanterns ot' the m's'linary type, and which may be easily and cheaply n'ninn'l'actured and its parts readily assembled.

Hm in; thus described the invention, what i 1 claim is:

1. lhe combination with a lantern having a chimney and a crown plate, of an extensible tube constructed in telescoping sections, one of said sections being secured to and do pending from the crown plate, and the. other section forming a shade, when the tube is extended, and a holder in which thelower end of the shade tits and which is arranged to bear against the body portion. of the font around the burner, said holder being pro- \ided with means for admitting air to the burner, as and for the purpose specified.

The combination with a lanteri'i having a chimney and a crown plate, of an extensiole tube constructed in telescoping sections,

'- one of said sections being secured to and depending from said crown plate and the other section forming a shade, when the tube is extended, an annular holder'formed at its u per edge with a cupped run 111 which t e lower end of the shade tits, said holder being 30 formed at its lower edge with a notch exlending therethrough, as and for the purpose specified.

3. The combination with a lantern having a chimney and a crown plate, of an extensible tube constructed in telescoping sections, one of said sections being secured to and de 1 pending from the crown plate, and the other section forininaia shade adapted to intercept
