UNITED STATES PATENT OFFICE.

GHRISTIAN H. PETERS, OF DANVILLE, ILLINOIS.

RAILWAY SlGNAb-LANTERN.

SPECIFICATION forming part of Letters Patent 385,877, dated July 10, 1888.

(No model.)

To aZZ whom it may concern;

Be it known that I, CHRISTIAN H. PETERS, of Danville, in the county of Vermilion and State of Illinois, have invented a new and Improved Railway-Signal, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure l is a plan view of a portion of my improved railway-signal. Fig. 2 is a side elevation, partly in section; and Fig. 3 is a horizontal section taken on line w 00 in Fig. 2.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to constructa simple and effective bloclcsignal for railways.

My invention consists in the construction and arrangement of parts. as will be hereinafter fullydescribed and claimed.

To the base A is attached a casing, B, which extends upward and is curved inwardly and provided with a collar, (t, for receiving the hollow glass cylinder 0. To thetop of the cylinder is fitted a hollow cap, D, provided with a collar, 1), fitted to the glass cylinder 0. The cap D and casing B are connected by bolts 0, which draw them into close contact with the ends of the glass cylinder 0. To each bolt is attached a plate, 0, for screening the bulls eyes which are not to be displayed.

To the center of thcbasc Ais secured a frame, D, in which is pivoted a wheel, E, having a flange, (7, upon its upper surface for receiving the metallic cylinder F, which is secured to the wheel E in any convenient way. The metallic cylinderFis provided with several open ings, c, behind which are placed the windows f, of dilferent-colored glass, and the sides of the cylinder I? are colored to correspond with the color of the bulls-eye inserted in it. In the present case there are three openings and three windows, the glass of each window being held in place by a flange, g, extending around the openings 0. The glass windows f are bent to conform to the curvature of the .inetallie cylinder I The wheel E carries a pinion, h,

which is engaged by a toothed sector-lever, G, pivoted in the frame 2, attached to the base A.

The sector-levcr G carries an armature, j, and is drawn backward by the adjustable retractile spring 7c. The electro-magnet His supported by the bracket Z, attached to the base A, the said magnet being held in position to act upon the armature j. The magnet His placed in the block-signal line, and when the circuit is closed by any of the well-known instruments used for that purpose the armature j is drawn toward the magnet, thereby turning the wheel E and cylinder F about one-third of a revolution. The cylinder F contains an incandescent electric lamp, m, the light of which is colored by the colored-glass windowsf.

The lantern may be used for block-signals to indicate when a section of the road is occupied, or it may be used with advantage at the crossings of the road.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. The combination, with the signal-lamp carrying a gear-wheel, of a lever having a segment engaging said gear and an armature, an electro-magnet for throwing the lever, and means for returning the lever to its normal position.

2. The combination, with the bottom casing, B, a cylinder resting thereon, the capD on top of the said cylinder, and the bolts connecting the cap and easing outside of the cylinder and provided with longitudinally-extending plates on their outer sides, of the rotary signal-lantern within the cylinder and an operating mechanism in the bottom casing, substantially as set forth.

3. In a railwaysignal, the combination of the casing B, the glass cylinder 0, the cap D, the wheel E, and hollow metallic cylinder F, provided with the windowsf, the sector'wheel G, carrying the armature j,the retractile spring is, and the electro-magnet H, substantially as described.

CHRISTIAN H. PETERS.
