ELECTIIQICy RAILROAD SIGNALIDIG DEVICE.

To aZLwh/om it may concern:

Be it known that I, HENRY A. HoEsoHEN, a citizen of the United- States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a certain new and useful Improvement in Electric Railroad Signaling Devices, of which the following is a specification.

The object of my invention is to provide an electric signalin device ada ted to be used for railroads and the like and adapted to be operated or actuated by the passage oi' a v' train over the track.

Referring-to the accompanying drawings, forming a part of this specification, and wherein like characters of reference denote similar parts throughout the several views,

Figure 1 shows al central sectional view on line X X of my invention 'secured to the rail. Fig. 2- shows a plan view thereof with portions broken'away. Fig. 3 4is aperspective view oi'thelshaped head as used in my invention, while Fig. 4 is a cross-sectional end view oi' a modification of my invention.

In carrying out the aim of my invention I use a-suitable housing A, which is secured to the rail B by means of the bolts a. Projecting through the vtop of the housing A is a movable head C, rovidedwith -the downwardly-extending eg 1 and at the extreme ends of the head C with the projections 2 2, against whicli'lwork suitable s rings 3 3, which are suitably secured to t e lugs 4 4, and ribs 4 4 which are secured to the housing A, and which normally support t e movable head C. It will be observed that I provide the projections 2 2 of the head C on one side with the downwardly-projecting lips 5 5 to keep the s rings 3 3 from working sidewise in case they siiould have a tendency to do so.

Suitably secured to the outer side of the housing A, it will be observed, is a housing D, into which is placed my generator, which consists of a plurality of permanent magnets 6 and the electromagnets 7, the permanent magnets 6 being secured to one end of the cores 8, which pass'through the electromagnets 7 and through the endt,` of the housing D. In placing my generator within this housingD it will be observed that it is protected from the weather and impossible to get wet from rain or snow.

Secured to the ends 8 8 of the cores 8 8 are the s'oft-iron pole-shoes 1() 10, against which the armature E is held, which arma- Specicaton of Letters Patent. Application filed May 2, 1905. Serial No. 258,465.

springs 3 are adapted to ture is suitably secured to the insulation 12 by means of the bolt or pin.13,vas' clearly shown in Fig. 1. Extending from the electromagnets 7 are the wires 14 and 15, which lead to a suitable si naling device 16, adapted to be actuated y the'current from the generator, which is generated when the train 1s assing in one direction only.

Fig. 4 almodiication of my invention is shown in which the armature E is secured to both being placed within the housing D to prevent the armature from getting wet and rusting. This rock-shaftv 17 1s provided with the arm 18, against which the leg 1 of the head C strikes and pushes downward. when'- ever the wheels of the cars pass over the head C in one direction, which thus reciprocates the armature and generates the current in the same manrer as shown in Fig. 1, which will now be described.

The operation of my device is as follows: When the wheel Z of a passing train strikes the head C from-the side, as shown in Fig'. 1, the wheel presses one end of the head C downward, thus pushing the leg 1 of the head C forward and downward, as shown in dotted lines, and thus causing the same trL come in' contact with one end of the armature E, thus releasing the armature from the pole-shoe 10 10, and as the wheel Z moves over the head C and when it leaves the same it throws the leg 1 in a position as shown by dotted lines Y, after which it is returned to its proper position by means of the s rings 3 3, which normally press upward on the lips 2 2 and hold the head C in its proper lace. VIn having 1the wheels pass over the Iiead C in this manner it will be observed that it reciprocates the armature E, thus generating fa current, which is communicated to the signaling device 16, as heretofore described, thus giving notice at a suitable4 point or crossing of an approaching train.

My signaling evice, it will be observed, will only enerate a current when the train is going in t e direction as shown in Fig. 1, thus causmg the signaling device to ring. When a train is going in the direction of the arrow move forward and downward, as shown by armature E.

In the drawin rs I have shown the head C as being made oiD a plurality of plates, one of the outer plates having the square projec- W, it strikes the head C and causes the leg 1 to the dotted lines Y in Fig. 1, thus missing the k'Patented May 29, 1906. I

a rock-shaft 17, said rock-shaft and armature IOO tions` or lips 5 vSand the other plates having the lower part of the projections or lips 2 curved, as shown. My object in having the head (j inade of a plurality of plates is that in case one of the head-plates C should happen to be broken it would not afl'ect the operation of the saine. Further, it can be readily noticed that a head could be replaced. Althouwh I have shown the saine comprised a pluraiity of sections or plates, l desire `to reserve the right to make the head C out of one piece, if so desired.

In case the aforesaid movable head C, vided with the downwarilly-extending leg 1 is pressed downwardly in use with semaphoies, switches, and gates the leg .l is so arranged that when the movable head C is pressed downward suitable spring-terminals may be brought into contact by means of Vaforesaid leg, thus forming a circuit Jfor operating said seinapliores, switches, 'and gates.

It is of course understood that my invention can be made of any suitable material or any size desired, and the saine can be used in connection with seinapliores, switches, and gates.

Having thus described my invention, what claim as new, and desire to secure by United States Letters Patent, is-

1. In a railrbad signaling device, the coin- PTO- bination with thc electric generator, the armature, tlie movable head provided with. the downwardly-projecting lcg for reciprocating i said armature when d epressed by passing vel hicies, and. springs for 'normally supporting aforesaid movable head, substantially as specified.

2. A railway signaling device comprisingr a suitable housing, of an electric generator, a pivotally-supportcd armature, a movable head partly projecting through and beyond the top of aforesaid housing, springs adapted to normally support said movable head at its extreme ends, said head being provided with a downwardly-projecting leg, said leg when pressed downward and forward by the passing car-wheels, adapted to reciprocate aforesaid armature, substantially as and for the purpose set forth.

3. In a railway `signaling device, the conibination orl a suitable housing secured to the rail, a second housing secured housing, an electric generator such as described and shown held within said second housing,a pivotally-supported armature adapted to be rcciprocatcd by means of the aforesaid head operated by the passing carwheels, causing a current to be generated which is communicated by means of wires to a suitable alarm, suitable springs adapted to normally support aforesaid movable head substantially as shown and described.

In testimony whereof I a'HiXiny signature in presence of two witnesses.
