f combination and arrangement of the several name, a. citizen of the United States, residing at Fremont in the county of Sandusky and State of Ohio, have invented new and useful Improvements in signals of which "the following is specification.

This invention relates to a railroad signal,

ing and is held i raised position until the train passes the crossing when a part actuated by the train releases the member and permits it to drop.

Another object of the invention is to provide means for lighting a lamp. when the member is in raised position.

This invention also consists in certain other features of construction and in the parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my-invention in detail, refcrence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of a railroad crossing'showing myinvention in use.

Figure 2 is an elevation of the parts shown in Figure 1.

Figure 3 is a longitudinalsectional v ew through the device.

Figure 4 is a plan view of the device.

Figure 5 is a fragmentary sectional view showingthe device in raised position.

Figure 6 is a detail sectional view. showing how'the cables pass into the housing from the pulleys.

'Figure 7 is a diagrammatic view of the circuits. 7

In these views A indicates the track and B the crossing. Thesignal means consists of a housing 1 placed adjacent the crossing and in which is movably mounted a column 2. This column is adapted to be raised by means of the motor 3, said motor actuating the drum 4 to which is connected the cables 5 which are fastened to guides 6 at the lower end of the column. The cables pass over suitable guiding pulleys 7. The guides 6 engage the rods 7 which are arranged within the housing. A coil spring 8 in the i Jesse's 115. jrufnniahuon, or FRE O T on-Io.

9" "a. teen ta seam,

hotter-n ofthe housing engages the teacher "the'colum'n the in towered aesiuon. An electric lamp 19' is *meunceel on the top of the eelamn a sever ieispiaeed over the lamp; said eoverheing supportenfhy the posts ,11 which are connected with the top c-f the column. The 10 will rest on the top of the heusing whenthe column is-in lowered p'ositioiiso that no lightW-ill "be-seen when the parts are inthis position.

Gontacts leer-e connected "with the toppit the housing and these contacts are eenneetedby the: conductors 1t with a source of supply.

Conductors 15 are carried by the column and these contacts are connected by the con ductors 16 with the lamp. These parts are so arranged that when the column is in raised position the contacts 15 will engage the contacts. 13 and thus complete the circuit to the lamp. The motor circuit is provided with a switch 17 which is adapted to be opened, by a projection 18 on the column when the column is in raised position. The

column is'held in raised position'by a latch 19 and this latch has a part arranged adja-.

cent one of the rails-so that it will be-engaged by the wheels ofa train so as to move the latch to releasing position and thus permit the column to drop. A'spring 20 holds the latch in engaging position.

As the train approaches the crossing it will close the circuit to the motor so that the motor will begin to actuate and thus raise of its circuit by the contacts 15 engaging the contacts 13. ,The partswill remain in this position until the train passes the crossing when the wheels of the train will operate the latch to cause it to release the column and thus the column will drop upon the spring 8 which acts to absorb the shock of the dropping column. This invention will give a warning that the train is approaching the crossing both by the light and the rising column. a v It is thought from the foregoing description that theadvantages and novelfeatures of my invention will be readily apparent.

I desire it to be'understood that I. may make changes in the construction and injthe no a combination and arrangement of the several parts, provided that such changes'fall within the scope of the appended claims.

What I claim is g 1. A signal of the class described comprising a housing, a vertically movable member therein, a motor for raising the member, means for closing the'circuit to the motor by a train approaching the crossing, means ,for breaking the circuit of theimotor when the member reaches a certain position, a latch for holding the member in raised position and means actuated by the train for disengaging the latch after the train passes the crossing. v

2; A device of the class described comprising a housing, a vertically-movable column therein, a-motor. for raising the column,

means for closing thecircuit to the motor byv a'train approaching the crossing, means for breaking the circuit to the motor when the column reaches a certaln POSltlOIl, latch means for holding the column in raised position, means for releasing the latch means byt-he train after it passes the crossing, a lamp on the column, and means for lighting the same when the column reaches its raised position.

3. A device of the class described comprising a housing, a vertically movable column therein, a motor for raising the column, means for closing the circuit to the motor by a train approaching the crossing, means for breaking the circuit to the motor when the column reaches a certain position, latch means for holding the column in raised position, means for releasing the latch means by the train after it passes the crossing. a lamp on the column, means for lighting the same when the column reaches its'raised positionand means for enclosing the lamp when the column is in lowered position; v

: In testimony whereof I afiix my signature.
