To all whom t may concern.

Be it known that JOHN F. MCCOY, now deceased, of whom the undersigned, MARY MCCOY, who resides in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, is the duly appointed administratriX, has invented a certain new and useful Improvement in Train-Stopping Trips or Obstacles, of which the following is a full, clear, and exact description.

Thisapplication is a division of an application for United States Letters Patent filed by the said John F. McCoy, Number 864,403, @ctober 1, 1914.

This invention relates to train stopping trips or obstacles adapted to be set up in the track by a trainman of a train that has been stopped, so as to protect such stopped train from accident by a succeeding train collidingwith it.

The invention has for its general objects to improve the construction of devices of this character so as to be reliable and elflcient in use, comparatively simple and inexpensive to manufacture, and so designed that when it has performed its function it automatically moves to inoperative position so that the track will be clear for traffic.

A more specific object of the invention is the provision of a staff-like trip having hingedly connected sections pivoted on different centers in such a manner that these sections can be held together in upright position by means which can be destroyed by the burning of a time fuse or by the blow of a train-carried element, whereupon the sections automatically swing downwardly to an inoperative position.

Another object of the invention is the provision of'a combined `trip and signal having the characteristics above referred to in combination with' means whereby the combined trip and signal can be positioned in only one way in the track. y

Another object is to provide a train-carried stopping device so designed as to operate to destroy an element which holds the two sections of the staff in upright position. With such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arran ement of parts which will be set forth wit par-i ticularity in the following description and claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention and wherein similar characters of reference indicate corresponding partsV in all the views,

Fig. 2 is a front view of the said stopping device;

Fig. 9 is a transverse section on the line 99, Fig. 8;

Fig. 10 is a detail side view of a portion of the trip; and

Fig. 11 is a vertical section o-f the signal fuse.

Referring to the drawing, A designates portion of the a trip-operated train stopping device whichv includes a valve or equivalent device 1 suitably carried by the train or car, whereby the propelling power can be cut of or the brakes set, or both, the device 1 being'actuated by a rock shaft 2 carried by a suitable part 3 of the locomotive or car, and on this rock shaft are oppositely extending arms 4 and 5 that are connected by links 6 and 7 with a pivoted trip-engaging element 8. This element is a frame of shallow V-shaped form in side view and comprises a pair of forward bifurcations 9 and a pair of rearward bifurcations 10, there. being inclined surfaces 11 at the center of the device 8 and between the bifurcations, each inclined surA face serving to have a wiping action on the trip, whereby the element 8 will be swung from itsY normal position so as to operate through the links 6 and 7 to actuate the device 1. The device 8 is pivoted on a bracket or hanger 12 to swing on a center 13, and the links 6 and 7 are connected at 14 and 15 with the element 8 at opposite sides of the center 13.k The opposed faces 16 of the bi-v The trip device Bis in the form of a staff r which has a non-circular lower end-18 to tit in a correspondingly shaped socket 19 of a socket plate 20. The socket plates 20 are permanently positioned in the track at suitably spaced intervals, and preferably each socket .plate rests on a tie 21 and is fastened thereto f in any suitable manner, as, for instance, by

spikes 22, Fig. 7, and by bolts 23 which pass through eyes 24 at one end of the socket plate and through a track rail 25.

The upper part of the staff-like tripA B is composed of two sections or members 26 and 27 which are connected by pivotsV 26a` and 27L with the base 28 of the staif. The pivotal centers 26a and 27a are arranged at different l y levelsso that ,the two sections 26 and 27 cannot Swingin parallelism, and consequently, if the two sections are held together they will remain in a vertical position against the action of their respective springs 29 and 30.

These springs are mounted on the base 28 and bent to throw the sections 26 laterally from a vertical position, or to the left in Fig. 8. The sections 26 and 27 are held together by a mutilatable and fusible ring 31 )applied to the upper end of the trip, and

when this ring is destroyed the members 26 and27 will move from a vertical operative position to a lateral inoperative position To assist in the proper mating of the mem- `" bers 26 and 27 one is provided with a longitudinal rib 32 and the other with a longitudinal groove 33 into .which the rib tits, as

shownin Fig 9. The ring 31 is adapted to be struck by they serrated surfaces 17 of the v train-carried stop element 8, and the serrations destroy the rings so that the trip will move to inoperative position, but before the members' 2,6 and 27 of the trip can move to inoperativeposition they engage the inclined surface; 11, whereby the stoppingy device is operated, and afterx the element passes.y the trip the members 26 and 27 swingl in a directiontra-nsverse to the track ontheir pivots .26? and 27a, and assume an inoperative posi- Y tion` .If a.visual'signalisdesired for day use, a flag-234 asindicated by dotted lines, Fig; 8, canbe held in a socket 35 on one of the mem'-- bers ofthe trip. For signaling by night a` .fcolonedf light fuse Cl may be applied'to the tri-p, such fuse having. itslower endl 36 con"- structed to enter a socket 37 formed by makingrecessesv in. the members 26 andi 27 of the trip, the ring 31 having a mouth 3S for facilitating the entrance of the signal device C into the trip. The device C comprises a rod of suitable inflammable material 39 having a protective casing 40 and a protective cap 41'. On the bottom of the fuse C is a conical hood 4:2 which is disposed over the fusible ring 31, so that the latter ywill not be melted" by the hot residue of the burning fuse until the fuse is almost entirely burned up, when the ring 31 will be permitted to melt and allow the trip to move to inoperative position. It is to be understood that the fuse C will burn a predetermined length of time to enable a train to proceed far enough to be out of the danger zone of a succeeding train, andthe fuse finally performs the function of rendering the trip inoperative, but if a-succeeding train should proceed without heeding the fuse, the trip device will be operative to stop such train. The bottom of the fuse is so constructed that it will havedirect Contact with the ring 31, so that the inflammable material of the fuse will finally ignite for the purpose just mentioned.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while l have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown i is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.

Having thus described the invention, I

claim as new and desire to secure by Letters train, said tripping deviceA being adaptedto i move into operative and inoperative positionsand when disposed in an operative position to engage a train-carried, valve-tln'owing device for opening the valve and applying the brakes, said tripping devi-ce including astai adapted to be supported in juxtaposition to the tracks and having a pair ot sections having a enacting rib and recess, and means to secure said sections together in elevated positions' and' adapted upon being engaged with the va-lve tlnowing device to be mutilated to permit the sections to drop out of tripping position.
