CHARLES C. BRIAND, OF REVERE, MASSACHUSETTS, ASSIGNOR TO PETER GRAY &, SONS, A CORPORATION OF MASSACHUSETTS.

LANTERN OR LAMP.

Specification of Letters Patent.

Patented May 20, 1913.

Application filed. October 8, 1908. Serial No. 456,834.

To all whom it may concern Be it known that I, CHARLES C. BRIAND, a citizen of the United States, residing in Revere, county of Suffolk, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Lanterns or Lamps, of which the following is a specification, reference being had to the drawings accompanying the same and forming a partthereof.

My invention relates to lanterns or lamps used particularly for signaling purposes.

The object of my invention is to provide means in a lantern or lamp so that the color of the light rays projected from them may be'quickly changed to display the desired color.

In the drawings accompanying this specification and forming a part thereof-Figure 1 is a side elevation of a lantern or lamp showing the movable lens-holders in dotted lines; and Fig. 2 is a sectional plan view taken through line 22, Fig. 1.

In the drawings, 1 represents the body of the lantern or lamp ;and 2 an angular piece secured to the inside of the body 1 and which is designed to act as a hearing or support for the guiding cone 3. The cone 4 is mounted to revolve in the cone 3, fitting fairly close therein. It is provided with a milled or knurled bezel or ring which secures the lenses 6 to the cone 4.

7 is a movable lens-holder which is pivoted to the angular piece 2 by the pivot 8 so that it will rotate thereon and .is provided with an angular slot 9 having a straight; portion and a curved portion adapted to re-.

ceive a pin 10 in such manner that saidpin can slide in said slot. The pin 10 is secured in the flange of the revolving cone 4 so that when said cone 4 is revolved the pin. 10 will slide in the straight part of the slot 9 and swing the lens-holder 7 upon the pivot 8 to present it to cover the central opening in the cone 4 so that any light within the lantern body 1 will shine through the lens 11 mountsecured in it a lens of another color. It is pivoted to the angular piece 2 by the pivot 13 and is provided with the angular slot 14 and a pin 15 slidable in said angular slot so that when the cone 4 is revolved the pin 15 will slide in the straight part of the slot 14 and rotate the lens-holder 12 upon its pivot 13 either to be presented to the opening in the cone 4 or swung to the position shown in Fig. 1. The lens 6 is preferably of white glass so that it will project white light rays. The other lenses may be red and green, or violet and blue, or any desired colors, so that when the lens 11 is presented in front of the opening in the cone 4 it will show onecolor and when the lens 16 in the lens-holder 12 is presented in front of the opening it will show another color.

A stop and locking arrangement is provided by which to position the lens-

holders

7 and 12. It consists of a spring 17 riveted to the inside of the cone 4 by the rivets 18 and 19. To the outer or free end of the spring there is secured a pin 20 which has an enlarged portion near the spring and a neck or smaller portion 21 near the head of the pin, as well as a head 22 on the pin. The stationary cone 3 is provided with three holes, 23, 24 and 25 and

slots

26 and 27 connecting said holes.

When it is desired to show a white light the pin 20 is pressed inwardly until the neck 21 comes opposite the slots, when the bezel 5 and the cone 4 are revolved until the enlarged portion of the pin will come through the central hole 24, thus throwing Ithelenses 11 and 16 away from the opening in'the cone 4. If it is desired to show the color of the lens 16, the pin 20 is pushed inwardly to the top 22 until the neck comes opposite the slot and the cone 4 is revolved upwardly until the enlarged portion of the pin 20 is opposite the hole 23. This moveenlarged portion goes in the hole 23, thus locking'the cone against movement and positioning the lens-holder 12 in position. The opposite movement will position the lens-holder 7 and the lens 11 opposite the central opening in the cone 1, thus projecting rays of the color of the lens 11 through the white lens 6.

It will be noted that in the construction herein shown, it is impossible to position both lenses over the opening in the lantern at the same time, for both operating pins are attached to the rotatable ring so that when one lens-holder is positioned over the light-opening the other holder is swung out by the pin acting in the straight part of the angular slot, and is locked by said pin sliding in the curved portion of said angular slot, thus locking the other lens-holder in an inoperative position. Furthermore, when the ring is rotated so that the ring-locking pin is in the hole-opening 24:, both lensholders are swung out into inoperative po sitions and locked in said positions by the ring-locking pin acting in conjunction with the two lens-holder operating pins secured in said ring, which, as before stated, positively hold both lens-holders swung in opposite directions out of operative position.

The form of the lens-holders may be changed somewhat and the method of positioning may be changed without departing from the spirit of my invention, as my invention covers mechanism to change the colors of the light rays projected from a lantern without the removal of the lenses or changes other than adjustment in the mechanism controlling the lenses.

\Vhat I claim is 1. In a lantern, the combination of a body part provided with an opening which shows the light therethrough, two holders having glass of different colors mounted therein, independent pivots for pivoting said holders to the body part of the lantern, a rotatable bezel mounted in the opening in the body part of the lantern, means connecting the bezel and holders for positioning the glass of either one of said holders in front of the opening in the body part of the lantern, and means for locking the bezel when one of the holders is in operative position and the other holder in inoperative position.

2. In a lantern, the combination of a body part having an opening therein for the radiation of light, two adjustable holders secured to the body of the lantern by independent pivots, glass of different colors mounted in said holders, a rotatable bezel mounted in the opening of the body part of the lantern having means connecting it to the holders for positioning either of the holders in front of the opening to cause the radiation of light through the colored glass mounted therein, and a locking pin operable from the outside of the lantern body for positively locking the rotatable bezel in such position as to present one or the other of said holders in operative position.

3. In a lantern, the combination of a body part having an opening for the radiation of light, a stationary casing secured in said opening, a revoluble casing revolubly mounted in said opening; holders pivoted to the body part contiguous to the opening, slots in said holders, pins secured in the revoluble casing slidable in the slots in the holders, a spring mounted on the revoluble casing, a grooved pin secured to the free end of the spring, a hole in the revoluble casing in which the pin is slidable, a plurality of holes in the stationary casing through which the pin is slidable, and slots connecting said plurality of holes and arranged to permit the grooved portion of the pin to slide therein.
