SIGNAL-LANTERN.

Specification of Letters Patent.

, atcnted Dec. 21, 1909.

Application filed March 1, 1909. Serial No. 480,700.

To alt whom it may concern:

mitt-red ring 8 is provided.

lle it known that I, Gnonon l Bnowivn, a i just outside of the lamp well I, and is adaptsubject of the King of Great Britain, residing in the city and district of Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Signallianterns; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

The invention to be hereinafter described relates to signal lanterns, and more particularly to a means for giving three signal colors by the same lantern.

Broadly speaking, it comprises a framework, a globe in the framework, a ventilator chimney above the globe, a lamp well below the globe, colored slides movably mounted in the chimney and lamp well, means for adjusting the slides, and means for locking the slides in adjusted position.

In order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings, like reference characters designate the same parts.

In the drawings: Figure 1 is a side elevation of the lantern; Fig. 2 is a perspective of the upper slide and its actuating ring; Fig. 3 is a similar view of the lower slide and its actuating ring; and, Fig. at is a vertical central section through the lantern.

The lantern frame and globe may be of the usual and well known type used by all large railways. Near the lower part of the frame, and directly beneath the bottom of the globe, is suspended a lamp well 1, provided with a tubular upwardly extending cylinder 2, adapted to receive the font 3. The font is provided with a circumferential groove a, adapted to seat resilient spring fingers 5 secured to the inner surface of the cylinder. In this way, the font is securely held in position while the lantern is swung to give various signals. Between the cylinder 2 and the lamp well 1 is movably disposed a cylindrical glass sleeve 9, colored red or green. This sleeve carries spring fingers 7, which act to space it from the lamp well. In order to raise and lower this sleeve, a

ed to slide over the same. Rods 10 travel freely in grooves 11, and connect the ring and lower end of the sleeve. Consequently, in order to raise the sleeve, it is only necessary to raise the ring to the tops of the grooves 11.

The ventilator chimney comprises two concentrically arranged cylinders 12 and 13, the inner one being suspended from the outer one, and the outer one being provided with a plurality of vents near its top. Between these two cylinders is movably mounted a second cylindrical glass sleeve let. The sleeve 14 is spaced from the outer cylinder 13 by spring 15, mounted on the sleeve. Similar springs or spring fingers may also be secured to the inner cylinder 12, if de sired, to space the sleeve therefrom. The upper and lower rings are alike, and the second sleeve is operated in the same manner as the first or lower sleeve. However, 011 the lower edge of this second sleeve are provided resilient clamps 16. These clamps are adapted to engage over the upper edge of the lower sleeve 9, and aline the two sleeves to make a continuous cylinder. In this way, the upper sleeve will be steadied when lowered and the lower sleeve will be steadied when raised. Leaf springs (3 may be mounted in grooves on the outer faces of the lantern body and adapted to engage and hold the rings 8.

The globe of the lantern should be made of crystal or clear glass, one of the sleeves of red, and the other of green, thus giving the three signal colors in a single lantern. I Assuming the parts to be in the position shown in Fig. 1, the operation of the invention is as follows: The leaf spring (3 on the upper outer cylinder 13 will be depressed to free the upper ring 8. When freed, the upper ring'will be forced downward, the sleeve 14 sliding freely in the grooves 11, and arryiug with them the springs clamps 16, which, in lowered position, will engage over the upper edge of the lower glass cylinder or sleeve 9 and lock the two in alinement. In its lowermost position, the upper ring 8 will again be engaged and held by the lower ends of the springs 6.

Changes may be made in the construction. arrangement and disposition of the several parts of the invention, without in any way This ring lies departing from the field and scope of the same, and it is meant to include all such within this application, wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with a lantern of the character described having a frame and a globe mounted in the frame, a lamp well carried by the frame below the globe and adapted to support a burner, a grooved ventilator chimney supported by the frame above the globe, a slide movably mounted in the ventilator chimney and adapted to be moved into and Withdrawn from the globe, a ring slidably mounted on the ventilator chimney, rods connecting the ring and slide and adapted to travel in the grooves, and means for holding the slide in adjusted position.

2. In combination with a lantern of the character described having a frame and a globe mounted in the frame, a lamp well carried by the frame below the globe and adapted to support a burner, a grooved ventilator chimney supported by the frame above the globe, a slide movably mounted in the ventilator chimney and adapted to be moved into and withdrawn from the globe, a ring slidably mounted on the ventilator chimney, rods connecting the ring and slide and adapted to travel in the grooves, means for holding the slide in adjusted position, a second slide mounted in the lamp well and means for holding the slides in alined posi tion.

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