I?) r/,// 10/101, if may concern.

Be it known that we, Janustl. O. Cones and Isaac I). Cones, citizens of the United States, residing at Harold. in the county of Greene and State of Missouri, have invented certain new and useful Improvements in Railway Signals and Gates, of which the following is a specification.

This invention relates to appurtenances used in connection with railways at crossings or other dangerous places where warning is required to be given of the approach of a train and a barrier utilized to prevent persons or animals from crossing the track.

The machine embodies audible and visual signals, a gate, and novel actuating and resetting means. To prevent accidental operation of the signal mechanism, two trips and adjunctive parts are employed, one trip when moved serving to throw the signal-operating mechanism into effective or working position and designated hereinafter as the signal-setting trip and the other trip when actuated serving to move the signal-operating mechanism and distinguished hereinafter as the signaloperating trip. A third trip, qualified by the expression gate-operating trip, is connected with the gate and when operated by the operating-train throws the gate across the roadway. The parts are returned to a normal position by a resetting-trip"operated by the train after passing the crossing or dangerpoint guarded by the signal.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

\Vhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which Figure 1 is a top plan view of a railwaycrossing equipped with signal and gate mechanisms constructed in accordance with and embodying the essential features of this invention. Fig. is a side view of the parts illustrated in Fig. 1. Fig. 3 is a detail view in elevation of the operating mechanism, on a larger scale, showing the relation of the parts after the signal-setting trip has been actuated. Fig. t is a view of the parts illustrated in Fig. 3, showing their relative arrangement after the signal and gate operating trips have been actuated. Fig. 5 is a detail perspective view of one of the trips. Fig. (i is a detail perspective view of the operating mechanism, showing the normal position of the cooperating elements. Fig. 7 is a detail view in perspective of the operating mechanism, the several elements being separate and arranged in a group.

Corresponding and like parts are referred to in the following description and indicated in all the views of the-drawings by the same reference characters.

It is to be understood that the invention is adapted for single or double tracks and for any system of railway required to be safeguarded at a crossing or other dangerous points. \Vhen applied to a single track, the mechanism is duplicated and preferably arranged upon opposite sides of the track, so that a train passing in one direction will operate one signal and gate only and a train passing in the opposite direction will actuate the other signal and gate. For double tracks each will be applied at the point to be protected with a signal and gate. It is to be further understood that the working parts are to be suitably housed to protect them from the weather and from being injured by animals and vehicles passing thereover.

Figs. 1 and 2 of the drawings show the invention applied to a single track, the parts being duplicated at each side thereof and arranged so that a train approaching from one direction will actuate one mechanism and a train moving in the opposite direction will move the other mechanism. Inasmuch as the mechanisms are duplicated a detailed description of one only will be given.

The track is indicated by the reference-numeral 1, and the crossing by the referencenumeral 2. A gate 5 is located at one side of the track, so as to obstruct the crossing when thrown into operative position. This gate may beof any usual type commonly employed for protecting railway-crossings; but the construction illustrated is preferred because of its simplicity and ease of operation. As shown, the gate comprises a bar A and arms 5 and 6 and is adapted to fold into a pocket 7, provided in the roadway adjacent to the crossing. The arms 5 and 6 have pivotal connection with opposite ends of the bar 4. The arm 5 is connected to a rock-shaft 8, so as to move therewith, said rock-shaft being journaled in bearings applied to an extension of a tie or to any suitable framework. The inner end of the rock-shaft is provided with a crank-arm 9, to which the power is applied for opening and closing the gate.

A signal is arranged at the crossing or other point requiring to be protected and is of the audible and visual type, the visual signal comprising a lantern to give warning by night and a semaphore to indicate danger by day. A post 10 carries the visual signal and a hammer 11 of the audible signal, said hammer being adapted to strike a gong-bell 12 when the post 10 is turned to give warning of impending danger. A crank 13, secured to the lower end portion of the post 10, is coupled, by means of a link or connection 14:, to a crank-arm 15 at the outer end of a rock-shaft 16, journaled parallel with the rock-shaft 8 and provided at its inner end with a bell-crank 17, from the arms of which project pins 18 and 19 in diametrically opposite directions. When the rock-shaft 16 is turned in one direction, the signal is moved to indicate danger, and when turned in the opposite direction the signal is moved to safety.

A rock-shaft 20 is arranged parallel with the rock- shafts 8 and 16 and is provided at opposite ends with crank-arms 21 and 22, the former being coupled to the signal-setting trip A by means of a rod, wire, or like connection a. The signal-setting trip A is located along the track at any determinate dis tance from the crossing, so as to be actuated by the approaching train in ample time to throw the signal-operating mechanism into condition for positive movement when actuated. The trip may be of any construction and arranged so as to be operated by any part of the moving train. A lifter 23 is provided for normally holding the signal-operating mechanism out of gear and may be of any formation so long as it subserves the intended purpose. As depicted, the lifter 23 is of link form,comprising side bars and horizontal rods. A link or link connection 24 couples the upper end of the lifter to the crank-arm 22, whereby movement of the rock-shaft 20 results in a corresponding movement of said lifter. A rock-shaft 25, provided at opposite ends with crank-arms 26 and 27, parallels the other rockshafts and has its crank-arm 26 coupled to the signal-operating trip B by means of a rod,

wire, or analogous connection 5. A dog 28 is pivotally connected to the crank-arm 27 and under normal conditions is held out of action by means of the lifter 23 by resting upon the upper rod or portion thereof. A guide 29 prevents vertical or lateral displacement of the dog 28, yet admits of a limited vertical and longitudinal movement thereof. The hooked end of the dog 28 overhangs the pin 19 of the bell-crank 17 and normally is held sufiiciently elevated therefrom by means of the lifter 23 to prevent operation of the rockshaft 16, even though thetrip B should be actuated or the connection I) drawn upon. However, when a train is approaching the crossing and actuates the signal-setting trip A the lifter 23' is moved to a position to admit of the dog 28 lowering at its hooked end, so as to rest upon the pins 19, thereby throwing the signal-operating mechanism into gear. As the train in its onward movement actuates the signal-operating trip B the shaft is rocked and the dog 28 moved, and its hooked end, coming in contact with the pin 19, rocks the shaft 16 and sounds the audible signal and throws the visual signal into position to give warning of the approaching of the train. When the train actuates the gate-operating trip 0, the shaft 8 is rocked and the gate pro jected across the roadway, as indicated most clearly in Fig. 4.

A rod, wire, or like connection 0 couples the trip C to a link 30, having an end portion provided with a longitudinal slot 31 to receive the arm of crank 9. The link 30 is pivotally connected to the connection 0 and rests upon the pin 18, and the upper edge of its slotted portion 31 is provided with a shoulder 32, intermediate of its ends, to engage with the pin 18 and rock the shaft 8 and throw the gate into operative position. So long as the rock-shaft 16 occupies a normal position, the link 30 will be held out of action, thereby preventing operation of the gate by actuation of the gate-operating trip C. When, however, the rock-shaft 16 has been operated, the pin 18 is lowered, thereby permitting the slotted end of the link 30 to descend and rest upon the pin 18, and upon actuation of the gate-operating trip C the shoulder 32, coming in contact with the arm of the crank 9, rocks the shaft 8 and throws the gate into position across theroadway.

The resetting-trip D is arranged some distance from the crossing, and a rod, wire, or like connection (Z, coupled thereto, has links 33 and 34 pivotally connected thereto, the link 33 having a slotted end 35 to receive the arm of the crank 9 and the link 34 having a slotted member 36 pivotally connected thereto and receiving the upper rod or portion of the lifter 23. After the train has passed by the crossing and actuates the resetting-trip D the links .33 and 34 are drawn upon and lock the shafts 8, l6, and 25 in an opposite direction, thereby returning the parts to a normal position. The link 3% rests upon the pin 19 of the bell-crank l7 and is provided with a hook 37, so disposed that when the resetting-trip is actuated the shoulder 37 will come in contact with the pin 19 and effect an oscillatory movement of the bell-crank 17 and a locking of the shaft 16.

\Vithin the purview of the invention the several trips may be of any construction and arrangement so as to be operated by the moving train. However, it is preferred to have them of approximately uniform structure and substantially of the form shown in Fig. 5, which illustrates each of the trips as consisting of oppositely-disposed pivoted bars 38 and 39, having their outer end portions downwardl y deflected, said bars being arranged adjacent to a rail of the track with their pivotal ends below the tread thereof, their inner ends slightly elevated, so as to be depressed by the wheels of the cars passing thereover. Links 4A) and *1 are pivotally connected at their upper ends to pendent lugs at the inner ends of the pivoted bars, the lower end portion of one of the links. as 4:1, being curved toward the link 1L0 and pivoted thereto, whereas the link 1 is extended below its point of connection with the link t1 and is connected to one end of a lever *2, the opposite end portion of which is coupled to a connecting-rod 43, which may be either one of the rods 1!, r, or 1/. A spring &-L is connected to the lever 42 for returning the bars to a normal position when relieved of the pressure of the car-wheels.
