Said inventionv consists of certain features or instrunientalities substantially as hereinafter fully disclosed and particularly pointed out by the claims.

in the disclosure of our invention, we suitably locate and secure in position upon a car, operated by a mo tive fluid, electricity or otherwise, at the forward or controller end thereof, or in an engine cab, the various parts as disclosed by the upper portion of Fig. 1; the parts in the extreme lower portion thereof being suitably secured in position at an ligible point upon the car or engine truck, within a suitable distance from the surface, and wherein l and 2 are two cylinders preferably yoked together as at ior otherwise, this being merely a detail incident to the assen'ibling of said cylinders for the uses of our invention. Within each of these cylinders is arranged a piston 4 whose diameter, however, is lcss than that of the inner cross-section of the cylinder, although suitably applied to the piston, above it are packing rings 5, of course, as indicated, .iilling the; cylinder in transverse section. The less dianietered piston provides for a certain amount of' surrounding space for the reception of air pressure or other pressure fluid as in delivering force or pressure upon the piston in returning itto its depressed or original position alter having been elevated as presently more fully disclosed. g

A roll or wheel (5 is hung or suspended below each cylinder from :1. preferably broad flat spring 7 having one end suitably secured and adapted to be coiled around a stud or pin 89 of the cylinder supporting casting and having a horizontal portion suitably supported in position for supporting each wheel or roll 6 and adapted to return said roll or wheel to its normal or original position after having been elevated by the shoe or trip 8, two trips or shoes 8, 88 being suitably arranged alongside of the track one for each roll or wheel, which will be further described later on.

An indicator 9 suitably equipped with a tape or ribbon 10 having indicia thereon, such as railroad stations, crossings, water-tanks, block-signals, or any other information it may be desired to impart to the .notorrnan or engineer, is suitably supported in position convenientlyto the latter. The tapoor ribbon 10 is coiled ,or wound in opposite directions upon two rolls 11 suit-' ably journaled in the indicator casing or housing. One of said rolls is hollow and has arranged therein a spring suitably adapted to deliver its tension upon said roll as thetape or ribbon is unwound therefrom in order to provide ior the reverse action of the roll when the ribhon has been unwound from thesame, and is to be reavennd thereon. Therecoil action of said spring effects the rewinding of the tape at the stated intervals by the action of the signal-actuating mechanism when the car has reached its destination and is performing its provided with a suitable knob or finger-piece for its convenient manipulation by hand, it being automatically held in engagement with said disk at its toothed end bva spring l3 arranged in said housing adapted to deliver its pressure upon said pawlv A link or arm 1.6, suitably pivoted for convenience upon a projecting portion 17 of the shaitoi one of the 15 rtape-earrying rolls, carries the detont or pawl 13 ior effecting the engagement of the latter with the disk said link or arm being connected to a rod 18 equipped with a suitably packed piston 19 arranged in a cylinder or casing 20, Said piston is subjected to the tension of a spring 21 coiled around said rod 18 and also inclosed Within the casing 20, for effecting the release of the detent alter the link, with the detent, has made its for-- word movement. To the lower end of the cylinder or casing 20 is connected a pipe 21 connecting with the cylinder 1, from which it receives air-pressure or like force for delivery to said casing or cylinder 20 for actuating, through said piston and sdjunctive parts, said detent, as when the trip 8 actuatcs the signal-operating wheel 6. The air-pressure at this juncture passes into the cylinder 1 via the air supply pipe 22 leading to the air supply reservoir (not shown) for delivery to the piston 4 and thence into pipe 21. A whistle 23, snitably applied to the pipe 21 serves as an audible signal when the aforesaid action of parts takes place, as will be reddily appreciated. A second pipe ill connecting with the cylinder 2 in like manner equipped as the cyl inder 1 as relates to a piston, &c., also connects with a.

cyli ndcr 25 provided in like manner as cylinder 20 with a piston carrying, by means preferably of an angular arm 26, an annunciator 27, being preferably a metalplute having noted thereon any word or symbol suggestive of extreme precaution or danger, the cylinder iheing arninged in connection with the open switch, derail, or flagging shoe or trip 8. Also connected with the pipe 24 is a whistle or audible signal 28 which serves as an additional Warning to the motorlnnn or engineer of approach to an open-switch or other danger point. A piston-equipped cylinder 29 is also applied to the pipe 24, whose piston A is subjected to the tension of a spring 30, the purpose of which will be apparent later. Also a pipe 31 leading to the high pressure air reservoir (not shown) is equipped with a. valve 32, having its handle 33 connected by a rod or link 34 with the spring-cushioned piston A arranged in the cylinder 29 for the retention initially or normally closed. Said pipe Bl has a valveequipped arm or branch 34 leading to the brake-cylinder for'applying the brakes simultaneously with the applying oi the danger signal. A still further pipe 35 having connection with the pipe 31 and cylinder 1 and provided with a nimnmlly-aetuated valve 36 provides for delivering air-pressure by suitably operating said valve, to the upper end of the cylinder, said pipe also having a brunch pipe connection 3'7 with the cylinder 2 [or a like purpose in connection with the latter.

hein suitabl" held in pin (2 or the air-cut off valve 32' ass st i The shoe 8 before referred to, suitably pivoted in. pi sition, rests at its free end upon an arm 38 pivoted to and between the members of a stud 39 fixed to a l, plate 40 suitslbly secured to the rail-ties. 'lo said pr 1- oted arm is connected by a link ll the upward curved or bent end of a; piston rod 4-2, whose piston 43 is spring seated within a cylinder 44 suitably secured in place upon the plate 40. Said piston adapted to ert pressure upon. a series or number oi preferably steel balls 45 upon which is superposed, within. 5 pipe-extension 46 of thecylindcr 44-, an upright'piston 47 arranged r immediately under, and adopted to engage the lmver surface of the shoe or trip 8,

It will he noted that, should the switch be left or thrown open, as by an oppo itely moving engine or otherwise, the hook. or latch 06 will, with the movement of the in incoiate parts connected to the switch, be deflected or luted over and past the can: (57, and thus provide for the disengagement or lease of said latch ruin the bar or cross-bend l'i ntly' the springpiston 44 will be thrust, by the action of its spring, for Ward, throwing the upright piston 47 upwardly into contact with, and elevating or setting the slide or trip 8.

It is further noted that, in event of an engine passing from the main track to the siding and deflecting or spreading the points of the switch-rails, which would its tension or pressure to elevate the piston 47 and set the shoe or trip 8 for actuating the signal upon an approaching engine, as aforesaid.

The shoe or trip 88 is stationary or not actuated as the shoe or trip 8, only being principally used for actuating a station or like indicator signal, although also adapted for sending in an audible OI WlIlStlG signal as above made apparent.

A portable trip or shoe 71, suitably adapted for being placed at any required point along the railroadtraek, as for flagging a train, is provided with spring presscd or adjustable jaw or cleat-like-equipped bars 72, 73 effective for clamping, or application to a rail 0 the railroad-track, as clearly disclosed by Fig. 10.
