Application filed September 20. 1911. Seiial No. 655,413.

To all whom it may concern Be it known that l. Pincx'rics E. BEACH. a citizen of the United States residing at Hal-wood Hines. in the county of Lnzerne and State of Pennsylvania. have invented a new and useful Railway-Switch. of which the following a specification.

This invention has reference to improvements in railway switches, and its object is to provide a means whereby the switch points are locked at either limit of their movement against accidental displacementwith relation to the respective rails. so that there is no possibility of the wheels of a passing train engaging the switch po nts in any manner other than the designed or proper manner.

in accordance with the present invention any suitable or approved switch stand may be employed. or a special switch stand may be utilized. and in conjunction with such switch stand there is provided a switch point lock soarranged as to engage on either side of each switch point close to the tree end thereof in a manner to hold one switch point closely against the rail into engagement with which it moved and at the same time hold the other switch point from movement toward the rail to which it is adjacent. and from which it spaced. The arrangement is such that by the act of throwing" the. switch, the locking means which is normally active to the switch points is moved out of the path of the points before the latter can be shifted from one posi ion to the other, and the act of resetting" the switch stand mechanism to hold the switch points in the new position serves to reset the locking means for holding one switch point in engagement with a respective rail in practically immovable relation thereto and the other switch point against movement toward the rail to which it is adjacent.

The invention will be bestunderstood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the understanding, however, that while the drawings illustrate apractical embodiment of the invention. the latter is susceptible of other practical embodiments, and, therefore, the invention is not limited to any exact conformity with the showing of the drawings but may be changed and modified in various ways so long; the salient features of the i invention are retained.

In the drawings:Figure 1 is a plan view of a portion of a railway track including a switch or turn-out and showing the invention applied. Fig. a section on the line of Fig. 1. Fig. 3 is a central vertical section of a switch stand constructed in accordance with the present invention. Fig. l is a section ()lhtil'e. line 1t of Fig. 3 with distant parts omitted. on the line of 1 but drawn to a larger scale. Fig. (5 is a section on the line 6 of Fig. 5.

Referring to the drawings there are shown track rails 1, 2, which may be considered as'inain track rails. and enter rails 3. 4, constituting the raits of a turn-out. Connected to the rail a switch point 5 and connected to the rent 2 is a switch point 6. and the two switch points and G are con nected together by junction bars 7. as is custoi'nary. the two switch points being thereby constrained to move together in the usual manner to bring the free-end of one switch point into engagement with inain rail and at the same time carry he free end of the distance away 1 other switch point a suitabic from the other main rail.

There isprovided a 5n stand comprising a basic member 8 of suitable construction designed to rest upon or be secured to extended tics 9", or to be mounted upon any suitable support adjacent the switch points. Mounted in the basic member is a sleeve or hollow column 9 substantially vertical when the switch stand is in installed position. and this sleeve 9 is supported in the switch stand base by a flange 1O situated on an inwardly directed annular noulder 11 formed on the basic member 8 near the upper end thereof, the said basic member being hollow tor lightness of construction. Above the shoulder 11 thebasio member has an upstanding portion 12' wnich defines arecess 13. preferably of squarecontour designed to receive a square extension 1% of a block 15 normally resting on the top of the extension 12. The sleeve 9 is cylindrical in form where extending through the basic member 8 and where eXtendin through the block 15. the said sleeve having an extension or head 16 above the block 15 and being there formed with a flange 17 above which the extension 16 is hollowed out, a indicated at 18, for a purpose iwhich will presently appear. Sur- Fig. 5 is a section v mounting the head 16 is a stem 19 carrying at its outer end'a target 20, such as is customarily employed in connection with switch stands.

' The head 16 on one side, that is the side remote from the hollowed out portion 18,

. is provided with ea'rs 21 to which is pivoted one end of a lever 22, the other end of which lever may be formed .into a handle 23 for axis inUsaid sleeve as well as moving in the direction of its longitudinal axis, the hol lowedout portion or cavity 18 of the head .16 permitting such'longitudinal movement of the shaft 28. The lever 22 is also con- .nected by a link 29 with the block 15, so

that movement of the lever 22 about its axis in the ears 21 will be participated in by the block 15, the flange or shoulder 17 limiting the movement of the block 15' and lever'2-2 in one direction.

The lower end of the sleeve 9 is formed with an arm 30 outstanding therefrom in a substantially radial direction, and this arm is connected by a bolt 31 or in any other suitable manner-with a link- 32, which in turn is connected to the switch point 6 and by the bars 7 to the other switch point 5, the arrangement being such that-turning of the shaft 28 about its longitudinalaxis will cause a movement of the switch points in one direction or the other, as the case may be.

Mounted in transverse relation to the track close to the free ends of the switch points 5 and 6 is a rock shaft 33 journaled in brackets 34 which may be made fast to one of the ties supporting the track rails 1 and 2, or may be otherwise mounted, as circumstances may require. The shaft 33 has fast thereto collars 35 close to the outer edges of the respective rails 1 and 2, these collars being either applied to the shaft and secured thereto in. any suitable manner, or may be welded to the shaft so as to be in fixed relation thereto. In the particular .may move for a short distance to permit ;-slight variations in the gage of the track 'so located with respect to an adjacent rail 1 or 2. as the case may be, that a lug 37 will etther enter between the free end of a re 'spective switch point and the adjacent rail,

or the switch point will lodge between the lug 37 and the respective track rail, in which latter case the switch point is held snugly against the respective track rail, so that it-may not then move independently of the rail for a distance sutficient to permit a wheel flange to enter between the switch point and the rail against which it is lodged.

The shaft 33 is extended to one side of the main track and there receives an arm 38 made fast to the shaft 33 to turn therewith, and thisarm is-connected by links 39 to one end of a lever 10, the latter being fulcrumed on a pin 41 outstanding from a lug 42 formed on the basic member 8 and nithe particular structure shown in depending relation to said basic member. The lever 40 is provided with an elongated slot -13 where traversed by the pin 41, so that the lever may have an extent of movement in the direction of its length. Theend of the lever 40 remote from the links 39 is forked or bifurcated, as indicated at 451, to straddle a block 45, and is connected to the'blockby trunnions 46. The block 45 is traversed by a short stem 47 formed on the lower end of the shaft-2S and is held thereto in any suit-- able manner, as by a nut 49 and washer 50, while a cotter pin 51 may be employed to By making the prevent accidental unscrewing of the nut 49 from the stem 47, which latter is suitably threaded for the reception of the nut.

Let it be assumed that the parts are in the position shown in Fig. l-with the manipu lating lever 22 locked as indicated in Fig. 3. Under these conditions the lugs or fingers 37 are substantially upright, one lug or finger confining the switch point 5 close to its free extremity to the rail 1, while the other lug or finger 37 is interposed between the rail 4 and the free extremity of the switch point 6. The lugs or fingers 37 are suitably proportioned to avoid any interference with the wheel flanges of a train, while at the same time performing the functions for, which these lugs or fingers are designed. In the particular structure shown the siding is connected to the. main track, so that a train traveling from right to-left as viewed in Fig. I will pass on to the siding; assuming.

Suppose now that it is desirable to establish the continuity'of the main track made up of the rails -1'and 2,the operatorunlocks the spectiveswitch points 5 and 6. Bythe time. ti

e shaft '28 is ,released so'that it may be turned aboutdts' longitudinal axis, the lugs or fingers '37 have been moved out of the )ath of the switch points and now by turnmg the shaft 28 about its longitudinal axis by means of the lever 22 the arm 30 and link 32 will cause a movement of the switch points from the position shown in Fig. 1 to the opposite position, that is, the switch point- 6 is brought into contact with the rail 4 and the switch point 5 is moved out of contact with the rail 1. To look the switch points in the new position, the lever 22 is depressed'until it is lodged between a pair of cars 24 when the corresponding pin 25 may be inserted and the usual padlock applied. On depressin lowered into t ie recess or cavity 13 designed to receive it, and this lowerin movement of the block 15 and shaft 28, which latter participates in the loweringmovement of the lever 22, results in the rocking of the lever 10 in a direction op )osite to that in which it was first rocked and the links 39 and arm 38 cause a partial rotation of the shaft 33 in the direction to move the lugs or fingers 37 into the normal upright position, when the lug 37 adjacent the rail 1 enters the space between the free end of the switch point 5 and the-said rail 1, while the lug 37 adjacent the point (3 engages the latter on the face remote from the rail 4 so as to lock the switch point into such intimate relation with the rail 4 that it cannot move away therefrom to any material extent and consequently there 15 no danger of a car wheel engaging the switch point in any manner except the proper'manner, nor can the switch point spring away from the rail, since it is positlvely locked to the rail between the corresponding collar 35 and the lug or finger 37.

It is to be observed that all movements of the parts are positive and can only take place at the will of the operator. Moreover, the switch stand cannot be set to the locked position in either direction unless a corresponding one of the switch points is in engagement with the respective track rail. By locating the lugs or fingers 37 close to the free or pointed ends of the switch points, any material, such as ice, or snow, or stones, or einders, or other obstructions, cannot find lodgment between a switch point and an adjacent rail and still permit the locking of the lever 22 the block 15 isthe rotatable member of the switch stand in either of its positions of adjustment, for even such yielding or spring as may occur in the device is not sutlicient to admit of the movementof the switch stand to either of its limits of travel when a switch point is held away from a respective rail by some obstruction when such obstruction is of a character to produce a liability of accident because the switch point does not lie snugly against the rail toward which it is moved.

, Should an obstruction interfere with the )roper positioning of a switch point, the lever 22- cannot be turned to the necessary extent to permit its being locked in one position or the other of its adjustment until the obstruction is cleared away, and failure to properly set the switch is at once apparent from the position of the target 20. By this means provision is made for the prevention of accidents due to improperly set switches where the visible indications may appear to be correct while the oints themselves are still in a position cangerous to the passage of trains. This desirable condition is due to the fact that the movement of the devices for holding the switch points is positive in both directions, wherefore the switch cannot be set fully to either position without the operation of the holding device and any failure of the switch points to move to their fully operative positions causes a stopping of the moving parts of the switch stand short of the full operative positions and the moving )arts of the switch stand cannot be locked nor can the target he turned to the proper indicating position.
