H. G. SBDGWIGK. ELECTRICAL TRAIN STOP.
APPLICATION FILED JUNE 14,1906.
with 745% UNITED sTATE's PATENT OFFICE.
ELECTRICAL TRAIN-STOP.
N o. 852,63 1. Specification 'of Letters Patent. Patented May '7., 1907.
Application filed June 14, lSlOG. Serialvlo. 321,761.-
Be it known that I, HIRAM G. SEDGWICK, a i
citizenof the United States of America, and a resident. of Mill Valley, county of Marin, State of California, have invented certain new and useful Improvements in Electrical.'
Train-Stops, of which the following is a full and clear speciiication, reference being had to the accompanying drawings, in which` Figure 1 1s a diagram showmg one section orb lock of a single track roadway; Fig. 2 a
' each similar view showing a slightly modified arrangement; and Fig. 3 a side elevation show- 1 ing the modified form of the stop ing magnet and the magnetically-controller train-stopping circuit on the-locomotive or other veiicle of the train. ,'Ihe'object of this'invention is to rovide an extremely simple block system ihr preventing collisions, means being provided ywhereby each train as it proceeds prempts a block or section of the roadway, preventing any train coming from either direction from entering the block until it is free of trains, the
means for preventing trains from entering the block `while thus preempt-ed being en.- tirely automatic and inde endent of all signals and the actions vof t 1e train-crews, as more fully hereinafter set forth.
In its preferred form this invention consists in dividm u the track into sections c constituting t e blocks, the rails in these blocks being suitably bonded. Between the ends of pair of adjacent blocks is arranged a short rail section t insulated lfrom the block. sections pro er. A portion, c', of each end i of each bloc section, as shown in Fig. 1, is
`. made neutral by being insulated from mail` l lsection c and the sh'ort section t. 40
Adjacentto the short section t, on each sideof the track or roadbed is arranged a artial circuit with a suitabl'ebattexyand with the short rail seo" -tionft and the. rails of one of the adjacent 4 5 block sections c; that is to say, this magnet .is in a circuit'whch. is broken at two points, vonevbreak voccurrin, ,r between y,themain block railsA andthe' other breakl between the short rail sections.- I nthe drawing the magnet at the ri ht side of the roadbed is connected -with t e block rails ahead and the magnet of theo'ther side is connected lwith the block rails next in the rear. The neutral rail sectiopsjc. are'insulated from all circuits andrails. f
adapted to be actuated by magnetism. In
the device shown an armature c is carried by a spring-retracted arm e, in such position that as' the train moves along the track it will pass close enough to the magnet to be drawn downwardly if the magnet be energized.
When thus drawn downwardly a circuit f f;
will be closediin which circuit a suitable bat'- tery and a brake magnet willbe included. Any other circuit-closin ployed, and it will. be ovious also that the brakel magnet'may be adaptedv to operate any suitable train-stopping mechanism, al-
a bra e-pipe venting device.
There wlll be two of these circuit-closers on each train, one at each side thereof, and a suitable switch will be arranged to .automatically cut out one or the other of these circuits by the.` reversal of the reverse lever of the locomotive, so that the armature onfthe right side only ofthe train will be subjected devi-cemay be em-` i thou h I prefer that it be arranged to actuate to the influence of the magnets on the roady train is on the block railsl the wheels and axles thereof serve to close the magnet circuit connected to each end of the block eX- cept at the point between the short rails b. It will be seen, therefore. that should another train pass onto the short section at either end of the block, the circuit at1 the right -hand side of that short section would be completed, thus energizing the magnet included in that circuit. Thus energizingthe magnet automatically actuates the armature carried on that side of the locomotive, completing the circuit on the locomotive and applying the brakes. This manner of. completing the circuits by means of two' trains is shown in Fig. 2 where is illustrated one pair of wheels of each of thel two trains approachingeach other. In this instance it w1ll vbe observed that the train on the short rails will be stopped by the magnet at the right of the roadbed. It will thus be observed that it lwill'bejimpssible fortwo trains to meet, either going `in the same direction or opposite directions, upon the same block.

The non-active sections a, shown in Fig.
long as the longesttrains, so t ata trainy cannot extend from the short ra'ils to the block railsand thus waste current. It will be4 observed that by this system I do away with all brushes on the locomotive and contacts on the roadbed, thus doing away with a yourcepf great'troubl'e. p
It'will -be observed that-,instead of magnets I may eiri'ployv suitable induction coils on the roadbed in which case a suitable deflecting needle or another i induction vcoil `may be mounted on the locomotive to close the brake magnet circuit as the needle or coil passes through the ield'of the-'r'oadbed coil; it ,will be understood, therefore, that wherever I employ the term magnet in the claims this term will have this broader significance.
What I claim and desire to secure by Letters Patent is 1. In a train-stoppingblock system, the combination ofthe main block rails suitably bonded, an insulated short rail section between the adjacent ends vof each main block,
y a magnet adjacent to each short rail section,
and a partial vcircuit including a battery and said magnet at each short rail section, this circuit being connectedl at one end'to one of the adjacent bloclI-sections 'and at vthe other .end to the shortrail section, for the purpose set forth.
2. In combination, aseries of main block rails suitably bonded-'an insulated short rail section bet,ween lthe ends of each adjacent block rail sections, a magnetic deviceon the vroadbed at each side ofeach short rail sec tion, and. a partial circuit for each magnetic f device, said circuitincludi-ng al battery and `havin its terminals a-t one end connected to the a jacent short rail section and the ter minals at the other end connected to the adl jacent end of one of'the block sections, for the purpose set forth.
3. In a block system of the type set forth,
' main block rails, short rail sections intermediate the main block rails, a neutral rail section between each-short rail section and the adjacent niain block rails, a magnetic device at either side of the roadway adjacent to each short rail section, and a partial-circuit for each magnetic device, said circuit includi-n a battery and connected at one Yend to t e short rail section and at its other end to the adjacent end of one of the block sections.
4. In a train-stopping block system,` a series of rail blocks having an insulated short rail' section between ther-n, a magnetic stopsections, this magnetic device being included in a partial circuit one branch of which is connected to the adjacent insulated short rail section and the other branch of which is con# ping device adjacent each of said 'short rail nected to the adjacent right hand rail of the 1 next block ahead, the rei'nainderof said circuit having included in it a batteryv and having one-end ccnn'ected to the left hand rail of the blockv ahead and its other end connected 'to the opposite short rail section, substaibA tially as and for the purpose set forth. y
In testimony whereof I hereunto aifix my signature in the presence of two witnesses this 3rd day of April 1906.
