DESPATCHERS TRAIN-CONTROLLING DEVICE.

. To all! whom it may concern:

following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to signals for use on railroads, and has special reference to a signaling system to be used by train despatchers to control trains passing over a track. I

' The principal object of the invention is to provide means whereby the train despatcher may release a semaphore arm to permit it to fall to a position indicating that the train is to stop.

Another object of the invention is to pro vide a means for releasing the semaphore arm which consists of a minimum number of parts, is therefore simple in construction,

and is cheap to manufacture.

With these and ther objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. s In the drawing: Figure 1 is a front elevation of one of the signal posts, the view being partlyin section, Fig. 2 is a side elevation of the same, parts thereof being'shown in sect-ion, and Fig. 3 is an enlarged detail of the semaphore lock.

Likereference numerals designate corresponding parts in all the figures of the drawing.

The sig '1 is preferably mounted on a -pole 16. Upon this pole is mounted a casing 17 wherein is held a pair of magnets 18 arranged to actuate an armature 15,). which 4 is held to s ide between guides 20 mounted on the sides of the casing 17. Formed in the "oottom of the casing is a centrally disposed transverse slot 17*. The armature 19 is in the form of a rectangular bar, and is so lo- Spccification of Letters Patent.

cated in the casing that it extends in a direction substantially parallel to the railroad. Below the casing 17 is a sectional casing 21. and mounted on the pole adjacent this casing is a semaphore '22, the blade of which is provided with an extension 23. This semaphore is so arranged that when raised the extension 23 lies behind the armature It). The blade is further provided with an arm 24 whereon is uiounted a bar 25 of suitable conductingmaterial,such as brass orcopper, and this bar is insulated from the extension by suitable insulation 26 of vulcanite or hard rubber, Within the casing 21 are connected contacts 27, which are spaced apart and which lie in such position that when the semaphore .arm 22 assumes the stop position or the position indicating that the train is not to pass. the bar 25 will lie across the contacts 27.

In operation, the semaphore arm is normally disposed in the position shown in full lines in Fig. In this position, the upper end of the semaphore is disposed within the transverse slot 17 of the casing 17 and the armature 1!) is disposed in advance of the extension 22-; of said blade. and serves to lock said arm against downward movement. \Vhen it is desired to lower the arm 22, the electro-magnet lb is "energized from any suitable source of electrical energy, and as a result. the armature it) will be elevated between the guides 20 to a distance sutiicient to permit of the extension 23 sliding thereunder, the Weight of the arm 22 being sufficient to cause said arm to assume its lowered position. as shown in dotted lines in Fig. 2. \Vh'en the arm is in itslowered position, the circuit (not shown) will be closed between the contact 25 and the contacts 27.

llaviiigthusdescribed the invention, what is claimed as new, is:-'

l. A signal system including in combination. a casing. an electro-magnet disposed within the casing, an: armature loosely mount-- ed upon the casing below the magnet, guides tor the armature carried by the magnet, a support disposed below the. casing, a semaphore arm pivoted to the support; a stop projecting from the arm for engagement behind the armature when said arm is up. and controlling means tor said magnet.

Application filed June 25, 1909. Serial No. 504.344.

2. A signal system including in combination, a casing including a bottom having a centrally disposed transverse slot formed therein, an elect-ro-magnet disposed within the easing how the slot, longitudinally disposed spliced guides depending from the magnet and disposed above and in spaced relation to the bottom of the casing, an armature loosely mounted upon the bottom of the casing below the magnet and between the guides and extending on either side of the slot of said casing, a semaphore arm pivoted to the support and adapted when up to have 0 its outer end disposed within the slot of the casing, a stop projecting from the arm for engagement behind the armature when said arm is up, and controlling means for said magnet.

In testimony whereof, I alfiX my signa- 15 ture; in presence of two witnesses.
