The crank 26 has 'an arm 35 which has a pin 36 fastenedtherethrough, which also passes through the end of a universal l-ink designated by 37, the other end of the universal link being connected bythe pin 38 to an arm extending from a sector 39, which sector is pivoted on' a pin 40 journaled in two up-standing bearings 41 and 42, best shown cotter pins which hold the pin 40 .in place;`

in Fig. l, one of the bearings, namely,41, being broken 1n Fig. 2 to more clearly show the construction of the sector; 43 designates 44 designates a .link connected to the sector 39 by means 0I" the pin 45, said pin being heldin place by the cotters 46; this link 44 serving as a connection between sector 39 andl l -end bent at right-angles and inserted in a hole in the sector and has the other end bent at right angles and inserted in av hole in they latchl. The latch 51 is of such a length that' its upper end coincides with the'ex` t-reme outer face of the sector 39 and has a slight beveled portion 55 for a purpose to be later described. l

By Fig. 6 is shown a detail' of the upstanding bearing 41, showing the'notch' 56 in its upper end, which is made of such a width that the dog 19, will lit nicely therein when in its lower position. Bearing 42, as shown in Fig. 2, has a like notch 5G formed therein..

Numeral 57' designates a shield, which is attached 4to the two bearings 41 and 42 and is for the purpose of preventing a maliciously inclined loperator from inserting a wire through the hole in the base-of the de.- vice through which the member 44 passes, and by skilful manipulation, lifting the member 19 out of engagement with the shoulder 49 so that an improper movement of the levers of the interlocking machine vmay take place.

Operatiom It is lto be understood that link 44 is to be connected-to that part of a lmechanical interlocking machine which performs, what is usually termed as. preliminary-locking, and would if the 'ordinary and well known .so-called* Saxby & Farmer improved interlocking machine were used,

be connected tothe rocker.' and if the so-v fwith the dog 19 resting upon theperiphery of the sector 39. The raising of the latch carried by the lever in either style machine, would, in the ordinary and well known manner transmit motion to link 44 to move sector 39 in thedirection of they arrow b, Fig. 2.

vand after the lever was reversed and the latch dropped, further movement vas is wel'l understood in the art, would be transmitted to the link 44 to further move the sector 39 in the direction of the arrow b. With the lever fully reversed in the case of either .mechanical interlocking machine mentioned and the latch dropped, the sector 39 would be movedin the direction of the arrow b to such an extent that the dog 19 would be over the cut-out portion 47, so that under normal conditions the dog 19 would drop directly in front of the shoulder 48.

In a great many constructions the lever of a mechanical interlocking machine is used to close the circuit of a signal'which is actuated by electricity so that the movement previously described would, in such case, clear the signal. turn the signal to danger, the latch would be lifted, thus actuating the link 44 to move the sector 39 in the direction of the arrow c,

F ig. 2, to such an extent that the dog 19v would bear against thesho'ulder 49 thus preventing further movement of link 44 until the dog 19 is raised, atthe sametime the latch 51 will be pressed in the direction of the arrow b, compressing the spring 53 so as regards the `sector 39 and lthe latch 51, is as represented by Fig. 4. The resultotI preventing further movement of the sector 39 and link 44 is to prevent the op-,

erator from dropping the latch after the' lever has been returned to the-normal position so that the vmechanical locking in the machine is not released and, therefore, no

conflicting routes 'can be set up, all of whichl .is well known in the art D and has been practised for many years. The electric locks heretofore invented and ject to one disadvantage, however, for .after the lever has been put in theo-normal position, some time'must necessarily elapsebefore the signal governed thereby, returns to normal position which, although4 slight, in a busy interlocking plant'results in considerable valuable time in the aggregate being lost waiting for the signal to return to the normal positionv and by returning to the,

normal position sending a current through the coils 11, so that the armature 12 is at-l If, now, it is desired to re' that at, that time the condition of the dog 19 used .have been suby mechanical t-racted and the dog 19 raised out of contact with the shoulder 49, so that the latch' oil? the interlocking lever can be dropped thereby releasing the mechanical locking governing the levers controlling the signals of conflicting routes.

In electric locks heretofore invented, it has been necessary for the operator to rcmain at the lever after placing it in such position that the current holding the signal in the clear position isrbrolren for he had to -be prepared to drop the latch with the lever in the normal position theinstant the current passed through the coils of the lock by virtue of the return of the signal to danger position, for, if he did not, the dog locking the sector would again drop in locking position, so that it would be-necessary if he did -not drop the latch at just the proper moment to again clear the signal by reversing the lever and then put the lever normal again, holding the latch up ready to drop it, the instant the coils of the lock-Were energized, and even when the operator was standing right at the lever when the old form of locks were employed, he failed many times to drop the latch at the proper instant. In applicants device, however, the great care and Watchfulness required of an operator is entirely eliminated. Applicants invention is particularly directed to astructure which Will obviate such loss ot time for With an electric lock constructed as is applicants, after the mechanical interlocked lever has been returned to normal position, the operator can go about other business and is not obliged to Wait at-the lever until the return indication is received from the signal, for whena current of electricity is sent through the coils 11 by virtue of the fact that the signal governed by the mechanical l lever has returned to the normal posit-ion the armature 12 is pulled toward the ends 'ot the cores 10, the dog 19 is raised, and

immediately the latch by virtue ot' the spring snaps under the dog 19 thereby holding it in its upper posit-"ion, the condition of the members then being as shown in Fig. 5 and at any time thereafter the operator may allow the latch-to drop thus releasing the mechanical locking controlled thereby. It is .to l.be understood .that in practice, however, on account of the fact that dog 19 is liable to l.springs ysaid dog adapted to engage bind if the full power of the mechanical lever latch spring is exerted upon sector 39, the' mechanical vlever is not returned to the normal position but is stopped a little short ot it, so that the latch rests upon the quadrant cit the mechanical. inter-locking machine and then, after the lock has been energized and the dog 19 Withdrawn, the lever is pushed the remainder of the distance to full normal position; for if the lever is placed in the t'ull normal position before the dog 19 .is raised, the spring on the latch of the mechanical lever Would bind sector 39 and dog 19 together so tightly, that the armature 12 would not be able to raise dog 19.

In order to prevent the latch 51 Afrom catching on vthe dog 19 When -the sector' is bcing reversed, the latch 51A is beveled so as to slide easily under the dog 19.

The circuitv controllers represented by4v 32 and metallic strip 29 on drums ofcourse, actuated simultaneously 39 and may be used in the to govern any desired 28 are, With the sector Well known manner circuits.

Having thus my invention and having described one particular physical embodiment and fully illustrated the same, What I claim as new and -desire to secure by Letters Patent, 1s:

` a pivoted sec-` In an electric signal lock, ter, a shoulder upon the sector, a dog, a memlier having a guiding slot for the dog, the shoulder, a latch pivoted to said sector and having its 'free end coinciding'v with the periphery of the,v sector, a spring for pressing the latch in one direction, means for limit-ing its movement in said direction so' that the end of the latch v.vill lie in `proximity tothe shoulder on the sector, means for 'moving the 'sector and thereby compressing the said spring when the dog is in locking position, and causing the shoulder to abut the dog thus preventing for raising the dog thereby allowing the Vspring to expand and force the latch under the'dog, so that the sector can be thereafter further moved.
