To all whom it Wtay concern.-

Be it known that I, RUssnLL AVERY, a citizen of the United States, residing at Sausalito, county of Marin, State of California, have invented an Improvement in Railway Signaling Devices; andIhereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an apparatus which is especially designed for signaling the presence of trains upon the line of track over which other trains are liable to approach and to give warning to the approaching train of such other train in time to prevent collisions.

It consists of a series of torpedoes or equivalent devices and means by which they are temporarily placed above the rails in line of the approaching train, so that the ol'licials of such train will be given an audible warning of the presence of another train upon the track in front.

It also consists in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a plan view of my signals. Fig. 2 shows the point of operation. Fig. 3 is a plan view of one of the casings and its contents. Fig. 4L is a vertical section of the same. Fig. 5 is an enlarged transverse section of the magazine and attachments. Fig. 6 is a plan showing torpedo and actuating-lever.

Frequent rear-end collisions occur upon railways by reason of the unexpected stoppage or detention of a train upon the track at a station or other point and where warning is not given the following train, believing the road to be clear, comes up without checking its speed, and disastrous collisions frequently occur.

It is the object of my invention to prevent such collisions by warning the approaching train by a series of audible signals so placed that ample time will be given to stop the train before it reaches the danger-point. These signals consist of torpedoes or equivalent explosive devices such as are used in connection with railway practice, and these torpedoes A may be mounted upon movable arms and connected by any suitable means with operating levers or mechanism 3, located at the point where the previous train may be standing. A single torpedo may be actuated in this manner and be replaced by another when expended. l. prefer to have a number of torpedoes in a magazine with mechanism by which they may be placed upon the track by connection with a distant operating-station and replaced as needed until exhausted.

Figs. 3 and i show the torpedo or explosive A carried upon an arm 2, which is mounted upon a vertically-tnrnable post l. This post has a lever-arm 5, to which is connected a wire or red 6, and this wire or red extends through suitable guides or protecting-tubes to a point sufliciently distant from the torpedo where it connects with the lever 3. 1n practice it is found that such collisions and accidents take place at stations, and the lever 23 would properly be arranged in close proximity with the station, the wires or connections following the line of track to a distance of a quarter or half mile or more from the station.

The torpedoes or explosives A and the vertical posts upon which the arms carrying the torpedoes are turnable are preferably contained within casings, as shown at 7, and in their normal condition the arms will-be turned. so that the torpedoes are concealed within the casings by the side of the track and at about the level with the top of the track. In practice it is possible to have a series of these torpedoes arranged at short distances apart, so that an oncoming train will strike the torpedoes when in place and discharge them successively, so that there will be no question about sufficient warning having been given to the train oilicials.

It will be the duty of all the oflicials of the train which has been stopped at the station to see that the lever 3 or its equivalent has been moved so as to swing the torpedoes out across the track at the instant when the train steps, so that another train following will discharge these torpedoes and give its officials the proper warning, so that the train may be stoppedbe fore reaching the station or colliding with the tain in front. As soon as the train which has been lying at the station moves out the lever 3 is moved to swing the torpedoes off the track and into their casings, thus leaving the track free for the next train, which will then pass without warning.

The operation of removing the torpedoes from the track may either be efiected by the direct movement of the lever or it may be effected by means of a sufiiciently-powerful spring 8, either connected with the line of wire at a point beyond the last of the torpedoes or in other suitable manner, so that when thelever is moved the spring will act to pull the connecting-wire in the opposite direction and swing the torpedoes off the track.

In order to maintain the proper tension between the diiferent levers 5, through which the rod or wire acts, I have shown the levers split at the outer ends, so as to form a clamp through which the wire passes, and this split end has aclamping-screw a passing through it. When the clamping-screw is turned so as to grip the wires, they will all be held firmly to the levers. If anyslack takes place, it is easily taken up by loosening the clamping-screws and pulling the wire or connection through until the slack has been taken up.

In order to maintain the apparatus in readiness for use without visiting it after the expenditure of a torpedo, I prefer to make a casing 7 large enough to form a magazine in which a number of torpedoes may be contained superposed one upon the other,as shown in Fig. 0. Each of the torpedoes has a projecting arm 9 with the end upturned, as shown at 10, and upon each side are projecting lugs 11. I/Vithin the casing parallel with the bottom and raised sufiiciently above are the guiderails 12, and as the lugs 11 project from the top of the torpedo they rest upon these guide-rails. The bottom of the casing is open beneath the line of torpedoes; but while the torpedoes are intact they cannot pass through, because of the lugs 11 resting upon the guides 12. The box 13 is a slide consisting of side bars movable on each side of and parallel with the exten sion 9 of the torpedo, and these side bars have inwardly-projecting lugs 14, which when the slides are pushed forward strike the upturned rear end 10 of the torpedo extension, thus pushing it forward and out through a slot or opening in the front of the case 7 through which it is movable, directly upon the top of the railway-rail B and in position to be exploded and crushed by a passing train. The slide 14 may be connected in any suitable way with the operating cord and lever. In the present case I have shown a bell-crank lever 5, having its angle pivoted upon the top of the post a and one arm connected with the operating rope or rod 6. The other arm, 2, is connected with a stud or pin 17, which is connected so as to move the sliding carrier 13, so that a pull upon the cord or rod 6 or equivalent actuating device will move the parts and project the torpedo, as previously described.

carriers are first pushed forward this hook will pass over the upturned end 10 of the extension 9 of the torpedo, and this can be effected because the frictional resistance to the movements or movement of the torpedo is made sufficient to allow of this action before the lugs 14: strike the plate 10. Then when the hook 18 has passed over the upturned edge 10 the lugs 14, contacting with it from behind, will push the torpedo out upon the track, as previously described, the surface of the box exterior to the case 7 being approxi-.

mately on the plane of the top of the track.

IVhen the torpedo is crushed by the passing train, it will be flattened down, and the projecting lugs or arms 11 upon each side will then be below the level of the guides 12, which are within the casing. The hook 18 will still be in engagement with the upturned rear end 10 of the plate 9, so that when the movement of the parts is reversed the hook will drag the torpedo backwardly into the casing and beneath the guides 12, so that when it arrives above the open bottom of the casing it will drop.

In order to cover and protect all the parts which have been heretofore described, I have shown the casing as made in two parts, the magazine 7, containing the torpedoes, fixed to or forming a part of the cover of the main box or casing 7, within which latter box the lever mechanism is contained.

The whole device is adapted to rest upon one of the cross-ties over which the rails are laid and preferably exterior to the line of the rail. The end of the box contiguous to the rail is so shaped as to fit the space formed by the head, the web, and the bottom flange, and this locks this end of the box in place with its top, as before stated, approximately level with the top of the rail and forming a surface over which the torpedoes move from the magazine. The opposite end of the box has a projection at the bottom with holes which serve to receive spikes, as at 20, and the whole device is thus firmly secured. The cover of the box carries a magazine, and the magazine has a separate cover. Both of these covers are locked by hasps and staples, as follows: The cover of the main box is secured by a hasp 21, turnable about a staple upon the end of the box, as at 22, and conforming to the outline of the upper part of the box, the cover, and the side of the magazine 7. Upon the magazine 7 isa TIO staple 23, and the upper end of the hasp 21 is slotted to lit over this staple. The cover oi the magazine 7 is hinged or otherwise adapted to close down upon the top of the magazine, and this carries a second hasp 24, the lower end of which fits over the same staple 23, so that a single locking device passed through the staple 23 secures both the cover of the magazine and the cover of the casing.

When the magazine is to be recharged, it is only necessary to disengage its cover and open it.

When access to the main casing is desired, the hasp 21 is disengaged and the cover of the case 7 is in condition for opening.

l have here described the device as being operated by mechanical means; but it will be manifest that it might be operated by compressed air acting through pipes upon pistons moving in cylinders and having the pistonrods connected with the actuating-levers 5 at each torpedo-station or by means of an electrical circuit and mechanism, which could be actuated thereby.

A motor or other well-known electrical de vice at each station would serve to move the torpedoes on or 01? the track.

I do not desire to limit my invention to any particular mechanism by which the movement of the torpedoes is effected.

The cable 6 may be connected with a switchlever, as at 6, so that when the cable is pulled to deposit a torpedo a switch will be opened to lead the train oli the main track to either a side track or a derailing device.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is
