.AUTOMATIC FOG- SIGNAL APPARATUS FOR RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 509,796, dated November 28, 1893. Application filed May 25, 1393. sees in). 475,469. (No model.)

To aZZ whom it may concern: I

Be it known that LJOHN GEORGE DIXON, a subject of the Queenof Great Britain, and a resident of Huddersfield, England, haveinvented certain new and useful Improvements in Apparatus Employed in Fog-Signalingon Railways, of which the following is a speci: fication, reference being had to the accompanying drawings.

This invention relates to apparatus for placing detonating cartridges or fog signals on railway metals in foggy weather. It is automatic in its action, and operates to remove the cartridge which has been exploded by a passing train and replace the same by a fresh cartridge which is held on the line in readiness for the next train so long as the ordinaryline signal is at danger. The said apparatus is controlled by the ordinary line signal wire or point rod and is placed in the operative or inoperative position by the signalman in the cabin or elsewhere simultaneously with the operation of the said line signal. The said apparatus remains in the operative position so long as the line signal is on and in that position it is operated by each passing train in such a manner as to throw out the exploded cartridge and replace the same with a fresh cartridge. The cartridges are contained in a suitable trunk or box which can be turned about apivo't toward and away from the rail. The normal position of the box is vertical corresponding with the off position of the line signal.

The movement of the box from the normal position toward the rail effects the placingof a cartridge on the rail, and the movement in the opposite direction from the vertical position, that is to say, away from the rail, replaces the spent cartridge with a fresh one. The movement toward the rail is effected by the Signalman, and that away from the rail is effectedby the engine or train.

In theaccompanying drawings I have shown how my invention may be conveniently and advantageously carried into practice.

Figure lis a plan of the apparatus for placing the detonating fog signals or cartridges on the rail. Fig.2 is avertical section of the same takenon the line at, m Fig. 1. Fig. 3 is a vertical central section taken on the line y y Fig. 2. Fig. 4: is a rear end elevation of the rocking movement of the said box.

compartment (J above the platform 0 same. Fig. 5 is a plan drawn to a smaller scale of one form of mechanism for operating the box shown in Figs. 1 to 4. to displace the spent cartridges and replace the same with fresh cartridges. Fig. dis a plan, and Fig. 7 is an elevation of a slightly modified form of this operating mechanism.

Like letters of'reference denote corresponding parts in all the figures.

Referring now to Figs. 1 to 4, A is a stationarybox or casing which is sunk in a hole in the permanent way by the side of the rail at the place where the cartridges are required to be placed on the line, and is firmly stayed as for example by a beam B or otherwise, so as to prevent rocking.

Inside the casing A is a long rectangular trunk or box 0 which is provided with a pivot C Fig. 2 at its lower. end resting in a suitable bearing formed in the casing, or is otherwise suitably supported to admit of a to-and-fro The upper end of the casing A is madesufficiently wide in theplane of the movement of the box 0 to allow of said rocking movement, the extent of which is limited by the ends of the opening A in the top of the casing.

C is a cover attached to the box 0 which cover extends over the opening A and serves to keep out the rain.

03(1 Fig. 2 are partition walls extending the whole length of the box 0 and which form an inner compartment 0 for the cartridges or detonating fog signals. 0 is a platform for supporting the said cartridges. Said platform is furnished with ears C O which project through vertical slots C Fig. 3 in the partition walls 0 and are attached by chains D, D that pass over guide pulleys D, D to balance weights D D Fig. 1.

E indicates the cartridges packed in the The uppermost cartridge is pressed against the top of the compartment which is constituted by a door 0 tridges when required. It is hinged at (J and can be held shut by a catch or otherwise. An aperture 0 is formed in the "front wall of the chamber 0 sufficiently large to allow of the passage therethrough of onecartridge at a time, and a corresponding opening Otis The said door is provided to admit of refilling the box with fresh car- TOC provided in the back wall to receive a sliding piece F which effects the feeding as hereinafter described. Front and rear tubular extensions C, C of rectangular section are formed on the walls of the chamber 0 for a purpose hereinafter explained. The sliding piece F which projects from the part 0 is furnished with a cross bar F at its rear end which bar works between two ears F F formed on brackets F placed one on each side of the apparatus for a purpose hereinafter explained.

G is a shaft supported .in bearings in a I bracket G fixed to the casing A; Said shaft is coupled by an arm G and links G G3 to the upper end or head of the box 0, and is loaded by a weight G on the end of an arm G so as to cause it to tendcontinually to pushthe box 0 toward the rail H. This tendency however is restrained by the pull a of the wire I of the ordinary line signal which this purpose.

. position of p N jectsthrough the bottom of its channel guide the box 0 in the upright position shown in Fig. 2'but allows the said box to fall forward toward the rail when the signal is on. The wire I is not attached directly to the box 0 but passes over a guide pulley-I and is secured to a long bar or weight J which is suspended in a channeled part J Fig. 3 formed outside the box 0. In the position shown in Fig. 2 the upper end of the weight J is in contact with the guide pulley I, over'which the wire 1 passes, and is thus prevented from being drawn out of its channel guide any farther. Any other stop maybe provided for When the wire I is slackened and the line signal thus allowed to go on, thebox C tilts toward the rail as far as it can go. The whole of the slack in the wire I is however not taken up by this movement of the box 0 and consequently the bar or weight J is allowed to descend in its channel guide. When the line signal is pulled off by the slgnalman, the weight J is first drawn up as far as it will go, and then the box C is pulled back to its upright position. In the lowest the weight J its lower end pro- J as, and for a purpose hereinafter specified.

K is an arm fixed on a short shaft K that passes' through the casing A. The arm K is inside the casing and its lower end is formed with a part K Figs. 2 and 3 which when the arm K is oscillated is adapted to strike the lower end of the weight J when the latter is in its lowest position, but which will miss the said weight when the latter-israised.

' K is an arm fixed on the outer end of the shaft K and connected bya link L to an arm L fixed on a shaft L, see Figs. 2 and 5, which shaft is loaded by a balance weight L mounted on an arm L fixed to the said shaft. By oscillating the shaft Lthe lever K is caused to swing to and fro and to strike the weight J when the latter is in its lowest position as above described. The balance weight L is sufficiently heavy to overcome when released when the ordinar si nal is off maintains" arm 0 the balance weight G so that when the said weight L is freed from restraint and the weight J is depressed, it will operate to push back the box 0 away from the rail as far as it will go.

Referring now to Fig. 5 M is a bar preferably about twenty feet long pivoted at M preferably on the outside of the rail H. Otis a shaft supported in suitable bearings O and having an arm 0 at one end that extends underneath the bar M and to which is pivoted a vpi 11 that projects into a small hole in the under side of said bar; the bar M may be otherwise supported by an arm of the shaft O. 7 O is a balance weight mounted on an arm 0 secured to the shaft 0, and which balances the bar M, and maintains said bar in an inclined position, so that its higher end projects about one andone-half inches more or less above the level of the rail. The pivoted end of the bar is depressed slightly below the rail. 0 is another arm secured on the shaft 0 and passing underneath and supporting acranked part of the balance arm L of the shaft L; the said, arm L is thereby prevented from descending until the arm 0 is first depressed by the passing of a train along the line. P is a dashpot the movable piston of which is connected with the shaft 0 by an arm P secured on said shaft and coupled to the said piston. The object of the said dashpot is to prevent the too rapid rising of the arm O after it has been depressed.

Q Figs. 1 and 2 is a metal bar secured to the side of the rail at the place where the cartridges are placed thereon and which serves to form a level support for said cartridges.

The operation of this apparatusis as follows, that is to say, assuming the line signal is on and the box 0 is therefore inclined toward the line so as to hold a fog signal thereon, then when an engine or train passes over the rails at the place where this apparatusis fixed it first fires the detonating cartridge and then depresses the inclined bar M and thereby partially turns the shaft 0 and lowers the The weight L being thus no longer supported, descends and partially turns the shaft L and through the arm L, link L and arm K operates to turn the arm K and cause the lower end thereof to press against the weight J which is then in its lowest position. The box 0 is thereby pushed back beyond the upright or central position, and the cross bar F of the slide F is brought into contact with and arrested by,-the rear stops F on the brackets F The continued rearward movement of the box 0 then has the efiect of pushing out the spent cartridge fromthe .jawO

gins to rise under the influence of the balance weight 0 but rises very slowly by reason of the dashpotPand hence-tiine-is given for the spent cartridge to be thrown out-of the machine and replaced by another cartridge in the manner above described. When however the bar M has returned to its initial position the arm K will have receded from the weight J and will thus have allowed the box 0 to return to the rail H and place the new cartridge thereon ready for the next train it the line signal is still at danger, or return to the upright positionif in the meantime the line signal has been taken off. During the forward movement of the box 0 toward the rail H the plate F is drawn out of the part 0 by the forward stops 15" of the plates F which stops engage with and arrest the bar F. Another cartridge is thus permitted to ascend from the box to take the place of that previously at thetop. It will be seen that any train which passes the fog signaling apparatus when the line signal is off will not operate either to discharge or to replace a cartridge because in the first place the fog signal is not then on the line, andin the second place the weight J being in its raised position the arm K whenoscillated misses the said weight and consequently does not push back the box. A cartridge is thus placed on the line only when the line signal is at danger and said cartridge after being discharged is replaced automatically by the passing train.

In the slight modification of the apparatus shown in Figs. 6 and 7 the incline M is provided with a'tail piece M which rests on an arm N fixed on shaft K of the signal apparatus which shaft is weighted by a weight N so as to operate the box 0, in the manner above described with reference to Fig. 5 when the tail end of the bar M is raised.

P is a dashpot to prevent the too rapid return of the bar M to its initial position after it has been depressed.

The slow movement of the apparatus to and away from the rail is an important feature of my invention inasmuch as the apparatus is thereby caused to work smoothly and eificiently and is not injuriously shaken as would bethe case if it were connected positively to the incline and operated suddenly by a passing train or engine.
