To all whom it may concern: the upper end of the tube, 15, extends the hub, 16,

Be it known that I, MALCOLM W. LONG, a citizen of of a horizontal planetary gear, 17, through which hub the United States, and a resident of Harrisburg, and gear said signal shaft, 10, extends, and is free to Dauphin county, State of Pennsylvania, have invented rotate. The said hub, 16 is secured to the upper end certain new and useful Improvements in Semaphore of said tube, 15,by means of screws, 18, passing through 60 Switch-Stands, of which the following is a full, clear, said tube (and a reinforcing collar, 19, thereon) and and exact description, reference being had to the acinto said hub, as seen in Fig. 4. companying drawings, of which Secured to the signal shaft, 10, by means of a through Figure 1 is an elevation, looking toward the track, pin, 20, is a casing, 21, in which is journaled a horiof a switch-stand in which my invention is embodied, zontal shaft, 22, carrying a planetary gear, 23, whose 65 the parts being in the position in which the switch is teeth engage those of the planetary gear 17. Said set for the main line, the target and semaphore so indicasing also incloses said planetary gears, preventing eating. Fig. 2 is an end elevation of Fig. 1, that i access of dirt or dust thereto. A semaphore blade, 24, looking in the direction parallel with the track. Fig. is mounted upon said horizontal shaft, 22, said blade 3 is a view similar to Fig. 2, but showing the parts in being secured to a bifurcated yoke, 25, whose limbs, 26, 70 position in which the lever-arm has been thrown over are fitted on squared end-extensions of said shaft, 22, to the opposite horizontal position, to set the switch beyond the casing, 21, being secured in place by nuts, for the siding, the horizontal position of the semaphore 27, screwed upon the outer ends of said shaft. The so indicating. Fig. 4 is a vertical section partially in signal shaft, 10, is also provided with a target, 28, se-

elevation, of the upper end of the signal shaft, and its cured to an arm, 29, extending from and secured to 75 incasing tube, showing the mechanism for operating said shait 1 the semaphore blade. Fig. 5 is a horizontal section as Having n w briefly described the construction of on the ine rv-iv Fig. g. 6 is a SCtiOH On t line my invention, I shall proceed with the description of :URJ, Fig. 4.

The vertical 40 its outer end with an operating weighted lever-arm, 3, signal shaft, 10, is also rotated degrees, thereby and on its inner end with a beveled pinion, 4, engaging causing the casing, .21 (which, it will be remembered, a segment gear, 5, secured to a vertical crank shaft, 6, is secured to said shaft) and the parts carried thereby, which is journaled in said casing, 1 and is provided, at to rotate, and during such rotation of the gear case, 21, its lower end with the usual crank, 7, connected by a the planetary gear, 23, is caused, by the stationary 45 bar, 8, with the switch, in the well known manner. planetary gear, 17, which is supported upon the tube,

Extending upwardly through the casing, 1, is a hub 15, to rotate on its axis, thereby rotating the horizontal extension, 9 from the segment gear 5, which hub shaft, 22, upon which said gear, 23, is mounted. The extension has, extending thereinto, the lower end of planetary gears, 23 and 17, are so proportioned that a vertical signal shaft, 10, the parts being secured the rotation of the signal shaft, 10, through an arc of 50 together by bolts, 11, or other suitable means. 90 degrees will cause said shaft 22 to rotate through a Mounted upon the casing, 1, is a tubular housing, slightly less angle to bring the semaphore blade which 12, bolted to said casing by bolts, 13, and extending is carried by said shaft, 22, from the downward position from the top of said housing, 12, being screwed into of Fig. 1 to the horizontal position of Figs. 3and 4, at the upper end thereof and held in place by a jam nut, the same time presenting said semaphore blade, 24,

55 14, ineasing said signal shaft, 10, is a tube, 15. Within at right angles to the track. This rotation of the signal shaft, 10, also carries the target, 28, from the position of Fig. 2 to that of Fig. 3, in which latter position it is presented edgewise to the observer. These latter relative positions of the target and semaphore indicate to a person coming down the track that the switch is set for the siding.

I would usually provide the top of the signal shaft 10, with a lamp-post, 29, upon which a lamp signal may be mounted for night service.

I remark that in practice I make the gear case, 21 of two parts divided horizontally on the line of the center of the shaft, 22, as seen in Figs. 4 and 5, said parts being secured together by means of bolts, 30.

The housing, 12, serves as a convenient support into which the lower end of the tube, 15, may be screwed, and said housing and tube, 15, not only serves to inclose the signal shalt, 10, thereby keeping dirt, &c. therefrom, but said tube also serves as a support for the stationary planetary gear, 17.

In assembling the apparatus, alter the parts have been connected together, the tube, 15, is rotated in the upper part of the housing, 12, until the semaphore and target are brought to the proper position with relation to the track, and the switch setting; whereupon the jam-nut, l4, secures said tube immovably in said position of adjustment.
