Application filed April 19, 1916. Serial No, 92,258.

To all whom it may concern:

Be it known that I, AVY V. JOHNS, a citizen of the United States, residing at Forsyth, in the county of Rosebud and State of Montana, have invented certain new and useful Improvements in Mechanisms for Raising and Lowering Lanterns, of which the following is a specification."

My invention relates to improvements in mechanism for raising and lowering lanterns, that is to say, means for raising and lowering lanterns used as railway signal lanterns, and one object of my invention is the provision of means which can be operated with ease and despatch for raising and placing in position the lantern upon the top of a supporting post, or raising-it to proper position upon the post with reference to the:

semaphore and for lowering the lantern to the groundwhen necessary.

Another object of my invention is the provision of means of the character and for the purposes stated, which can be operated with ease to raise or lower the lantern and fit or place it in proper raised position, which means will be simple in construction, durable and inexpensive to manufacture and from every point of view thoroughly efficient and practical.

With these objects in view, my invention consists of mechanisms for raising and lowering lanterns embodying novel features of construction and combinations of parts sub stantially as shown, described and claimed herein.

In order that the construction in detail and the operation of my improvement may be fully understood and the advantages which it possesses may be appreciated, I

have shown in the accompanying drawings a mechanism embodying my improvements. Figure 1 represents a side elevation of the complete invention used for raising and fit- V ting the lantern upon a supporting post, the lantern and mechanism being shown in full lines in the operation of'being'raised, and the lantern being shown in dotted lines as it is about to be fitted to the post support. Fig. 2 represents a side view of my inven tion used in connection with a supporting post carrying a semaphore and for raising and lowering the lantern in connection with a semaphore. Fig. 3 represents a detail view of the hood or guide for the bail of the lan tern and the pulley which receives thecord for raising and lowering the lantern, and

the upper end of the hood 8, formed with slits'9, providing guides for the bail of the lantern, as w ll'presently appear, and also having therein a, shaft 10 forming the mounting for the guidepulley; 11. Passing.

over said guide pulley 11, is the cord 12, one end of which 13 is connectedwith the bail 14 of the lantern 15 and the other end of which passes through the guide 16 over the guide wheel 17, mounted in said guide 16, the lantern being also provided opposite said wheel 17, with a cleat 18 adapted, when the lantern is raised to proper position, to fit upon the bracket 19 secured upon the upper end of the supporting post, the shaft 3 carrying a yoke 20, which serves to guide the cleat 18 of the lamp to said bracket 19.

The construction described refers particularly to Fig. 1, in which the lantern is supported on the upper end of the post and serves as an ordinary signal lantern at railway crossings, and other situations, while in the construction illustrated in Fig. 2 and used in connection with the semaphore 21, I provide the bracket 22 secured to the post near its upper end and on one side, said bracket engaging the cleat 23 of the lantern and supporting the lens 24: in rear of the semaphore color signal 25, in which construction the bail guiding hood and its cord guiding roller are adjusted in proper relation with reference both to the staff and the hail of the lantern as well as to the semaphore and the supporting post.

From the foregoing description taken in connection with the drawings, the operation of my invention will be readily understood, and it is apparent that when the cord is drawn upon that the lantern is elevated to thertop of therpost with the bail thereof guided into the slit of the hood, and that t the slit causes the lantern to be positioned Patented J an. 9, 1 917.

cleat thereof to fall upon and fit on said bracket, and thus support the lantern upon the top of the post. In Fig. 2, the operation is identical, only that the position of the hood With reference to the stall ,is reversed and the bail of the lantern is guided into the slit of the hood and directed to the supporting bracket, and in proper position with relation to the semaphore.

It will be understood that the hood may be easily adjusted vertically and placed on either side of the stafi, also that the operating cord may be secured to the post by a suitable clip orv anchoring device 27, and that the mechanism can be operated with ease and Will perform its functions in an eliicient and practical manner,

I claim:

1. In a mechanism for raising and lowering lanterns, the combination with a suitable support, a vertical staff carried thereby, an arm adjustably secured to said stafi, a hood mounted on one end of said arm and having a pulley secured therein, and a cord passing over said pulley and having one end secured to the bail of the lantern to be raised and the other end free and passing through a guide mounted on the body of the lantern.

2. In a mechanism for raising and lowering lanterns, the combination with a suitable support, a lantern engaging bracket carried thereby, a vertical staff mounted on said support, an adjustable arm carried by said staff and having a hood mounted on its outer end, a pulley journaled in said hood, 7

a cord passing over said pulley and having one end secured to the lantern to be raised and the other end free and passing through a guide mounted on the lantern, a cleat on the lantern for engagingthe bracket on said support, and means carried by the vertical staif for guiding said cleat to cause its engagement with the bracket.

In testimony whereof I afiiX my signature in the presence of tWo Witnesses.
