To alltwhonz it may concern Be it known that I, WILLIAM ROBINSON', of Brooklyn, in the county of Kings and State of New York,4 have invented a new and useful Improvement in Electro-magnetic Signaling Apparatus, for use at crossings .on railroads, and other purposes, of which the following is a full, clear, and exact description, .reference being .had to the'accoinpauying drawingibrining part of this specification, and in which- Figure 1 represents a longitudinalelevation, and l Figure 2, a plan of my improved apparatus asapplied to a. line of railroad.

Figuresi and 4 are front and side elevations of a modified construction of circuit-closer used in said :1p-- paratns. 4

My invention is applicable to the operation of approach-openingor closing gates, and audible. or visible signals, by a vehicle while in motion, and [is mainly designed for` usc ,at crossings and other'places or breaks on railroads, but is not restricted to said use,

although the invention will only here be described in such relation.

It consists infvariou's combinations and peculiarities in the construction of circuit-closers and breakers in an electromagnetic signaling apparatus, whereby the number of batteries to perform a certain work is re duced, and a most ciicient4 and reliable actionis obtainedforthe apparatus.'

Referring, iu the first instance, to'figs. l-and 2 of theaccol'npanying drawing A represents a line. ot' railroad, and B acrossing C is one of'thev circuit-closeis for operation-by a movin rtrain;Y rlhis closer vis composed in part of Va' lever,- having armaturesc e at its one end, and dporated by a magnet,d, or lcve'rye.

y A spring, jf. serves to draw said lever down at its opposite'end-iuto notches of 'a circuitfcl'osing lever g',.

as represented.; Points hh and m m complete the circuit, through a batt-ery, D, wires i, and anda signal E, operated by lsaid battery through amag'net, It'.

. supposing a train t'obe moving in direction .of the arrow y, it is Acaused lto bear upona lever, l, wl'iich acts on the circuitfclosing lever y, bringing the points h'h in contact with the points m m, which completes the circuit, when the spring f draws the lever b into the lower notch of the lever g, thus holding the circuit closed. l

When the train arrives at an independent .circuitcloser, F, beyond thecrossing, or at any particular point, it vcloses circuit through wires o 1i q s, a battery, G, and the magnet d, which latter, operating .on-the armatures co and lever b, throws said lever. into or Opposite the upper n'otch of the lever g, wh'eua spring,

r, draws away the points vlt h, leaving themain circuit f open, and lowering the visible signal E, orstopping the ringing-of a bell, H, in suitable connection by wires with the battery D.

A train passing inthe oppositedirection will press on the lever e ot' the circuit-closer C last, `and leavethe main circuit open', serving the same purpose as the 'magnet d. The circuit through F is activeonly while the wheels oi' thc train pressvon thelever u, a spring,

o, keeping the'- circuit broken when the. pressureot' the wheels is'removed.

G' is another circuit-closer, situated on ill-c oppovsite side of the crossing B, at a distance of half 'a mile,

(more Or less,) from the crossing. 1t is similar to the circuit-closer 0, excepting that the spring /rf holds the circuit closed, linstead of open; also, pressure .on the lever lopens the circuit, and the lever b', being drawn down into the lower notch ofthe circniprclosing 1n' the Operation of this "circuit-closer, the magnet d' acts in a direct manner on the closer. T-he train approaching the crossing B in the direction ofthe arrow z, pressure on thele'ver c' raises the lever b', and allows the spring fro act, closing the circuit, when it is left closed, the train passing onto the-'independent' crcuit-closcr F', which 4operates through thewircs p o s q, the magnet d' and battery G. The main cir-- cuit through the cilcujit-closer C passes through the By theseseveral connections the battery G is kused with two distinct eircuit-close1 s, Fand Ff; to complete two circuits through the magnets and d' independcntly of eachother; also, 'the circuit-closers 0 and C' independently operate the signals E or E through a single battery, D. In this way'ay multiplicity 'o f bat terics and complicated `mechanism for Operating the signals is avoided.

. In figs. 3 and 4 is shown a, niodiiied constructionfof the circuitlcloserQby which the lever 11,'thatholds the circuit closed, lies against the circuitfclosiug lever `g, and is drawn under it by a spring, f, when the cir- Leuit'is closed by' tho lever. 4. y

The battery D, as hereinbefore observed, may be.

made to operate not only the signal E, but also the signal H, either independently of E, trough a. circuit-closer, or in connection with it, by suitably arranged mechanism, thus makingonc battery serve several purposes.

Again', the one signall H. may be operated by sup# I plementary circuit-clusters arranged -iu proximity to the track outside of or beyond the circuit-closers C O', using either the same battery D, oran independent battery, to signal ata station the location of the train on the track, or otherwise give an alarm, independen' tly A .anni @fine BROOKLYN, NEW YORK.

of its operating the visible'or other signal E, or gate, at the crossing. Thus the-'circnit-closer shown in figs. 3 and 4 may be used for such purpose, and be connected with the battery D by wires a? a* nt' an independent circuit, as represented.

lhe circuit-ciosers O C might bepiaccd away from the track, andbe operated by a magnet or magnets tin-ought any simpie circuit-closer acted upon by the train. In the circuit-closer C the circuit is kept closed by means ofthe lever b, while in the circuit-closer C' the lever b serves to keep the circuit open,lthe spring r keeping it closed.- Weights may in every case take the placey of springs, andv must be regarded. as ille equivalents thereof.

iVhat is here claimed, and desired to be secured by Letters Patent, is

1. The combination, with the circuit-closer@ o r C', of the lever b or b', so arranged that said ievrr holds the circuit-closer in position when opened or closed, substantially as specified.

2. The spring r or fr', in combination with the cir- Y cuit-closing lever g or g', substantially as and for the purpose indicated.

3. The combination of the lever b or b', the springs f r or f r', and the circuit-closing lever g or g', substantially as and for the pui-'pose herein specified.

4. The magnet d or d', so arranged with reference to the circuit-closing lever g -org that the charging of said magnet shall openthe main or addrtional circuit, substantially as described.

5. The magnet d or d', in combination with a circuit-closing lever, g or g', of a main or additional cir cuit, and a circuit-closer, or F', of an independent circuit, essentially as and for the purpose or purposes described.

6. The combination of the lever b or i1", the signals E and H, or either, with abatterygD, and the'circuitclosing` lever g or g', operating essentially as specified.

7. The wirese, cf, and w, so combined orarranged with a single battery, D, a signal or signals, and two or more circuit-closers, C C', that a circuit may be closed and signal operated independently by either of said circuit-closers, essentially as herein set forth.

8. The arrangement of the wires p q s o' o if s with the magnets d d', circnit-clcsers F 13",. and battery G, so that said battery will charge one of the several magnets d d independently, through' or by different circuit-closers F F', essentially as 'and for the purposes described. j

9. Thecircuits w i iw, and a2 ai, so arranged with reference to a battery and eircuit-closers that two or more circuits may be closed, and two or more signals be operated independently of each other, by one 'and the saine battery D, substantially as specified.
