. My. invention relates to a new and useful Ji o.

improvement in railway switches, andihas for-its object to provide a device of this character, in which .the trip lever may be mounted relatively near the switch point, said 'triplever remaining unset until the train-has entered the siding, and when set;

b may be operated vertically by each succeed- ;i'ng car oft-he train until the last car has passed the'switchpoint, after which should [the trip lever be operated the switch will be immediately .closed, thus preventing any imishap to a through train should the switch have been left open by negligence.

5 QAh ther-Objectofthe invention is topro- ..vide means for'holdi'ng the switch point nlevsr. I

' point either open or closed, thus preventing open while the train is passing into the siding, and having means in cenjunction .wlth

Ithe first named means for setting the trip to provide a-means for locking theswitch I tampering by unauthorized persons.

With these ends in view, this invention I. consists inthe details of construction and combination of elements hereinafter .set

forth and then specifically designated which this invention .appert-ains may understand how to make and use the same, I will 1 describe its constructionin detail, referring ,by letter to the accompanying drawing forming apart of this specification, in which- Y I Figure 1 is a plan view of a track showing a'siding leadingtherefrom and having my improved switch applied thereto.

.A'still. further object of the invention is Patented Dec. 119M.

4:, a side elevation. of that side of the track from which runs the siding.

In carrying out my invention as here embodied, A represents the main track, B the siding and. C the switch point. 4 To the switch point beneath the same is secured a.

tube D by means of a screw E or its equivalent, so that as said tube is operated the switchpoint will move with it in the same dlrection for opening and closing the switch. In the tube'D is mounted a helical spring F, it being coiled about the rod G, one end resting upon the head H of said rod, the other end against the tlange Iv of the tube.-

This rod is fastened to a bracket J, or some other immovableportion of the switch by the nuts K; 'the spring F is so situated that when the switch point is opened, said spring is compressed between the end of the tube and the. end of the rod, and when the switch point is released the spring will expand,

thus closing the switch.

Upon one end of the tube D- is mounted the casingL, having a vertical opening M and a horizontal openingN. In the vertical opening is mounted the sliding rod 0, hava ing a foot P,'a portion of which'is beveled, as at Q, for a purpose to be hereinafter descr ibed. Said rod 0. is provided with a horizontal opening R and has its upper end threaded as at S, onwhich is mounted the weight T for normally holding fthe rod 0 downward. Y

U is a switch lever pivoted to the bracket V and to the former is pivoted the linkW, one end of which'is pivoted to the switch rod Y, said switch rodhaving a notch. Z therein and having its free end beveled as at A. This switch rod may pass through a suitable bracket B, then through the openingsN and R in the casing L and the rod 0 respectively.. The end of this switch rod rests within the tube D and when moved toward the switch point, its beveled end will .pass into the opening C in the pin D which pin is mounted within the tube D and passes through an opening (1-) in the under side of said tube, thus raising said pin and disengaging it from the opening F in the stationary block or bracket g, and when this pin D is 1 disengaged 'from the opening F, the vswitch pointwill be unlocked and again be operated.

The pin D being longer than the inside height of the tube .1), or of such length that it will not operate Within the tube it is necessary to form an 0 ening 2 in the top of the tubeto' permit said pin D to pass therethrough, and in order to prevent outside in-- terference with said pin I provide a cap E which covers the opening 2 and is secured to the tube. As said cap is at one time upon one side of the rail A and at another time upon the opposite side, an opening 3 is formed in said rail to permit said cap to pass from one side to the other.

From the foregoing description it will be seen, that by turning the handle end of the switch lever U over toward the switch oint, it being understood that the switch is c osed, the switch rod Y will be moved inward with relation to the tube D, the beveled end thereof disengaging the pin D from the opening F unlocking the switch point, since said switch point' is fastened to the tube D, at the same time the notch Z in the switch rod Y will be brought into alinement with the rod 0, and as the notch Z is of greater Width than the rod 0, said rod will drop into the notch because of the weight T. When in this position the, switch lever U is operated in the opposite direction, which will draw the switch rod U outward,and as the rod 0 is in engagement with said switch rod, and said rod 0 is mounted in the casing L, which is mounted upon the tube D,- these last named parts will be drawn outward, thus opening the switch, since said switch is securely fastened to the tube D. By this action the spring F will be compressed and when the tube is released, as will be hereinafter described, said spring will expand, and close the switch.

G denotes aholding member, which is a long strip of metal conforming with the curvature of the siding and is mounted adjacent one of the rails on the outside thereof, and is sutiiciently removed from said rail at the switch point to prevent it from being engaged by the wheels of trains using only the" main track. Said holding member is pivoted to the links H at I and these links are pivoted to some stationary brackets J at K. These links are so placed that as the holding member G moves downward it will move slightly horizontally. Said holding member is normally held upward by'a spring L mounted in the base tube M placed beside the track and over which telescopes the cap tube N, which is pivoted to the holdingmember G, at O. Said holding member is limited in its movement at one end by the hide and stop P. The holding member a is produced sufficiently wide at Q, to cause it to rest behind the end of the tube D when said member is moved downward, and when in-this position, should the switch be released the tube will be prevented ft'om moving, causing the switch to remain open until the holding member G is released, and when this is released the train has passed beyond the switch point.

Passing beneath the tracks is the rod R, having the end which is adjacent the casing L bent at right angles to the body of the rod, as at S, and this extension normally rests in a vertical position. On the opposite end of said rod R is securely mounted the arm T, which is provided with a slot U, and in this slot operates the pin V mounted upon the sliding member G, so

that with any downward movement of the holding member G the rod R will be rotated, causing the extension S to be moved toward the casing L, causing the catch W to pass beneath the foot P. This catch is provided with a noseX andhas afinger Y produced from one side, with which engages the extension S to force the 'nose X of the catch beneath the foot P. This catch is pivoted at Z to a rod A which is journaled in the bracket 13*. On the opposite end of this rod is mounted the arm C to the upper end of which is connected the cable D or its equivalent, said cable being fastened at E to the trip lever F uivc ed at G beside one of the rails at some suitable distance from the switch point.

From this description it will be seen that when the switch is opened the catch V is out of engagement with the foot P, therefore the trip lever F is unset or rests below the surface of the rail. Since the switch will not be opened unless the siding is to be used, it is unnecessary to set the trip lever until the train has passed into the siding, and in so doing the holding member G will be pressed downward, causing the arm T to rotate the rod R, whose extension S will engage the finger Y of the catch VVQforcing the nose X of said catch beneath the foot P of the rod 0, but because of the weight T and the friction between the rod 0 and the switch rod Y, said rod 0 will not be disengaged from the'switch rod Y, as the nose of the catch passes beneath the foot P, the free end of said catch will be moved downward, rotating the rod A which through the medium of the arm C of the cable D will set the trip lever F and if the train is long enough to extend back over the trip lever F the wheels of the last cars.

ber is of suthcient length so that a wheel rests upon the same, at all times said holdthat h z-netheraler e Y, this balding F "set; If the switch point is leftopen after the train has passed into the siding and a through train is passing, the wheels thereofwill engage the trip lever F depressing the same, a ndvthrough the medium' of the cable ,D'? and the arm C will rotate therod A lifting the nose X of the catch W ,which'Will lift the foot P and the rod f: O," disengaging the same from the notch C through train pass'while the other train' ison the siding, then as said train passes from.

the exact details "of construction here shown,-

in'theswitch rod 'Y. At this point the spring F will be allowed to expand, moving the tube D to close'the" switch, thus permitting the through train to pass safely. vAs

' the switch is closed, the tube D slides in the bracket g, and when the pin D alines with the opening F it will drop therein, securely locking the switch point. Should any the siding to the main track it will first engage the holding member G to prevent the closing. of the switch until afterthe last car has passed through the switch, then as said' holding; member G is released, with the next movement of the trip lever F the switch will be closed behind the train.

Of course I do not wish to be limited to as these may be varied Within the limits of the appended claims without departing from the spirit ofmy invention. I
