To all whomit may concern: r

lie it known that l, BUTLER J. HAsKrNs,

a citizen'of the UnitedStatearesiding at;

lilansas Gity, in the county of Jackson and it'll State of Missouri, haveinvented certain new and useful Improvements in Electrical Block Train titoppage and Signal-Setting Systems,

otwhich the following is afspecific atlon.

This invention relates to electrical block train stoppage and signal setting systems,

and the object is to produce a closed circuit system whereby the electrical connection of the rail members 011 the block by the entrance oil? a train into such block or the breaking of a rail, shall, in addition to settingithe'semaphores protecting such block, as common,

etlect the application of the brakes on atollowing train andprevent it from entering the occupied block; i

features of construction and organization of parts as hereinafter described and claimed; and in order that it-may be fully understood" drawing, in which: i i Y Figure 1, is a dia reference is to be had to the accompanying Fig. 2, is a diagrammatic side view showing the operative relation between the track system and the electricalvequipment to cogoperate therewith which is carried by a lli till

train. a a

tectedby housings 16 and 17, and the former is equipped with an inclined guard 18 at the end from which the approach of a train T occurs, in order that any loose part dependinglow enough to strike the coil, may ona counter the guard and be deflected upwardly thereby. From the foregoing taken in connection with the drawing, it will be apparent that whena train leaves one block and enters another, it shunts the track circuit (through i the Wheels and axle) from thesolenoid in the block just passed to ermit the core 9 of said solenoid to drop and thereby break the connection between conductors and 11;

i and thusleave the coils 14 and of the said unoccupied or passed block susceptible to energization m. a manner hereinafter ex- Mounted upon each train is the following equipment; 19 and 20 are coils, the former normally energized, supported beneath the engine in such position that they shall pass over coils 14: and 15, so that the magnetic field of coil 19 shall inclose coil 14: at the moment coil 20 is above coil 15. If at this time the block ahead is not occupied by a train nor the rails of said block otherwise electrically connected, or a rail displaced or broken, the coil 14 will be unafl'ected because the solenoidof the same block'is energized and the core" thereof consequently engaged with the adjacent contacts 10 and 11. On the other hand, if the rails of the block ahead are connected by a train or otherwise,

and areintacuthe circuit between coils 14 and .15 isnot shorted, hence the proximity ofrcoil -19 to coil 14 produces an induced currentPthrough coils 14 and 15, the energization of the latter energizing the coil 20-atj the time just above coil l5.--for a a purpose hereinafter explained. Magnets 19 and 20 are preferablyprovided with housings 21 and 22 corresponding to housings 16 i and 17 if desired, and housing 22 is equipped with an upwardly and forwardly inclined guard 23 to perform the same function for coil 20 as the guard 18 performs for coil 14.

,oil 19 is connected by a conductor 24: to a dynamo 25 on the engine, and the latter is connected by, a conductor 26 through a magnet 27 and conductor 28, to a movable contact or lever 29 held normally by a retractile spring 30 against a contact 31, connected by i conductor 32 to the coil 19 This circui't is normally closed so that 0011 27 may hold the armature 33 attracted,.said armature be- I ing mounted upon a lever 34 for holdin aweighted'arm 35 in elevated posltlon.

weighted arm is to operate a valve 36v of any suitable type controlling the air brake line 3710f the train, and to release said arm to connected'to lever 34? to trip the same from 'theweighted arm when the circuit l: the dynamo is broken. v a

i is ajmagnet 39 electricallyconnected by con-' i. :duc'tors il-and 42' tothe coil 20. Fromthe' ,foregoing,'it will be seen that when one -.efiect the o eration of thebrakes, (not shown),-of't e train, retractile spring 38 is through Arranged adjacent movablecontact or lever 29 and an armature 40 carried thereby,

block isoccupied by'a train-and therefore efi'ects a'break in the circuit through 7 the ,solenoid' 6 in the block to the rear of the .bccupied block, the short circuit through coil 14' established by. conductors 1O and-11- 'and core 9 is broken, assuming that a train is block B, it. will be seen-that when the coils 19Y2Iidf20offa' train-in block A are respectively in superposed relation [with coils14 and 15, a: currentwill be induced coil 19', through coils 14 and 15, and by thelatter a; current will be induced through- .coil 20, conductors tland 42, and electrotween lever29 and contact 31.

' It" will be-apparent'that the shunting of ;:a solenoid out of circuit in one block may, 'as'he'reinbefore suggested, occur through the fall of a bridge, the displacement of a rail or the connection of the rails by a wire in the next block-ahead.

From, the above description it will. be

' understood that the embodiment of the invention may be in various forms as regards its form, detail construction and organiza- ,tion of parts, without departurefrom the principle of construction shown or the'scope oi the appended claims.
