Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed March 20, 1905, Serial No. 251,108.

To all whom it may concern:

Be it known that I, CHARLES M. MoGEHnE, a citizen of the United States, residing at Beaverdam, in the county of Hanover and State of Virginia, have invented certain new and useful Improvements in Railway-Signals, of which the following is a specification.

This invention relates to railway-signals, and has for its objects to provide a comparatively simple device of this character which may be inexpensively produced and installed, one wherein the signal-lamps will be at all times thoroughly protected against inclement weather, one in which the semaphore-arms may be properly manipulated and the lamps readily lowered for cleaning, filling, or other necessary attention and readjusted to signaling position, and at the same time one whereby necessity for the operator leaving his office to operate or attend the signals is wholly obviated. I

Further objects of the invention are to provide simple efficient means for operating the signaling devices, a signal apparatus which may be employed for block or train-order systems, and one which will overcome the necessity for stopping fast or through trains to receive what are known as caution-cards.

To these ends the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a perspective view of a signaling device em bodying the invention, a part of the casing being broken away. Fig. 2 is a detail side elevation of a portion of the post, showing another position of the semaphores. Fig. 3 is a detail view of one of the semaphore-arms. Fig. 4 is a front elevation, partly in section, showingaslightly-diiferentembodiment of the invention. Fig. 5 is a side sectional elevation of the same. Fig. 6 is a horizontal sectional plan on the line 6 6 of Fig. 4.

Referring to the drawings, 1 designates a hollow post composed of sheet metal and constituting a box or casing, preferably of rectangular form in cross-section and sustained by a rigid vertical standard or support 2, to which it is attached in any appropriate manner, said casing being equipped with a door 3 and having formed in its side walls 4, which face parallel with the road, a plurality ofo'ppositely-disposed openings or bulls-eyes 5, by preference arranged three on each side and in vertically-spaced relation.

Housed within the casing 1 is a series of three lamps 6, spaced vertically to accord with the spacing of the bulls-eyes and suspended upon a cable or analogous flexible element 7, arranged for travel over a pulley 8, suitably sustained at the top of the casing, the cable being threaded through staple-guides 9 in the casing and normally wound at its lower end upon a drum or Windlass 10, journaled in bearings at the lower end of the casing and provided with an operating-crank 11. It is well to mention at this point that the lower end of the casing and the Windlass will in practice be situated within the signaling-house, and thus freely accessible to the operator, whereby he may without leaving his office lower the lamps for filling, trimming, or giving other necessary attention thereto and thereafter readjust them in signaling position.

Fulcrumed upon the side walls l of the easing, upon pintles or axles 12, is a plurality of semaphore-arms 13, corresponding in number to the number of bulls-eyes 5 and disposed, respectively, adjacent to and for cooperation with the latter. These arms are each provided with a pair of bulls-eyes contrastingly colored and termed, respectively, the pri mary bulls eye 14 and the auxiliary bulls-eye 15, either of which may be brought into register with the adjacent opening or bulls-eye 5. The axles 12 are strengthened by braces 16 and the arms or paddles each provided with a hub 17, having a projection or pin 18, to which is fastened one end of an operating rope or element 19, designed for operation to swing the semaphore on its pivot. The operating-ropes 19, which correspond in number to the number of semaphores, are threaded through staple-guides 20 and are operable from within the signaling-house, as in the instance of the rope 7.

In practice the post 1 stands in position for the semaphores on one side to be employed in signaling trains approaching from one direction and those on the other side trainsapproacl ing in an opposite direction, while the pins 18 normally stand horizontally with the arms 13 vertically disposed, as seen in Fig 2, under which conditions the bulls-eyes 5 will register with and be covered by the secondary bulls-eyes 15 of the semaphores, these latter bulls-eyes all being transparent. It is to be observed in this connection that the primary bulls-eyes of the upper and lower semaphores, which are designed for use, respectively, in block systems and train-order signaling, are colored red, while the corresponding bullseye of the intermediate semaphore, which serves as asubstitute for the usual cautioncard, is green, the paddles of the semaphores being colored in part to agree with the color of their respective primary bulls-eyes. When it is desired to signal an approaching train, the operating-cord of the proper semaphore is released, whereupon the arm, which is suitably weighted for the purpose, will swing by gravity to horizontal position, with'its bullseye 14 covering the adjacent opening 5. After the train has passed, the arm is returned to normal position through the medium of the operating-cord, which may then be secured.

Referring to Figs. l, 5, and 6, in which certain features of the device are brought to a higher order of perfection, it will be seen that within the casing 1 there are provided a pair of oppositely-disposed vertical tracks or guides 21, on which the lamps 6 are arranged for travel, the lamps being in this instance provided with seats or recesses 22 to receive the guides. Also in this form of the device the lamps are hung upon an endless cable engaged with and operable by the windlass 10 for raising and lowering the lamps for the purposes hereinbefore set forth, it being understood that the lamps will in their travel and owing to their engagement with the guides 21 move steadily and evenly. Aside from these differences the construction and operation of the device are identical with that hereinbefore described, it being obvious that through these differences the construction as a whole is brought to a somewhat higher state of perfection.

From the foregoing it is apparent that I produce a simple eflicient signal admirably adapted for the attainment of the ends in view, it being understood that minor changes in the details herein disclosed may be resorted to without departing from the spirit of the invention.

Having thus fully described the invention, what is claimed as new is 1.
