UNITED STATES PATENT OFFICE.

RAILWAY-SWITCH.

Specification of Letters Patent.

Patented Nov. 2, 1909.

Application filed June 15, 1909. Serial No. 502,236.

To all whom it may concern:

Be it known that I, ALBERT A. Sorro- MACHER, citizen of the United States, residing at Lisbon, in the county of Ransom and State of North Dakota, have invented certain new and useful Improvements in Railway-Switches, of which the following is a specification.

This invention relates to railways and refers particularly to an improved switch employed in connection with the same.

The invention has for an object the provision of an improved switch which automatically closes upon the passage of atrain thereover, unless purposely held open by the hand of an operator when the train is.

running at a slow speed to place the car on a siding so as to prevent accident to the train by reason of the train unexpectedly running upon the siding.

The invention further contemplates the provision of a switch mechanism which will normally be in a position to direct trains from the siding and which necessitates the manual setting and holding of the same to direct the train upon the siding.

A still further object of this invention is the provision of a switch mechanism which is locked in a closed position and is so formed that when the lock is tampered with or removed the switch mechanism is in such position as to be automatically operated to close upon the passing of a train.

For a full understanding of the invention and the merits thereof, as well as to acquire a knowledge of the details of construction and the means for effecting the result reference is to be had to the following description and accompanying drawings in which;

Figure 1 is a perspective view of the improved switch mechanism in a closed and locked position, the same being applied to a track and a siding, and Fig. 2 is a top plan view of the same disclosing the mechanism in a semi-open position, the lock being removed, the operating lever being disclosed in a full open position in dotted lines.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring more specifically to the drawings in which is illustrated an embodiment of the invention, the numerals and 11 designate the rails of a section of the main track provided with the switch points 16 and 17 which lead to a siding 14. The points 16 and 17 are attached to a draw bar 15 which extends transversely beneath the rails 10 and 11 and projects at one side of the main track.

The mechanism employed for throwing the points 16 and-17 includes a shaft 20 which is vertically journaled through a switch stand 19 and which is formed at its lower end with an arm 21 which is inwardly and laterally extended from the stand 19 for engagement with the outer ends of the draw bar 15 through the employment of the link 22. The upper end of the shaft 20 carries an arm 23 which is extended outwardly and provided with a loop or eye 13 at its outer extremity for the reception of the rounded extremity of a reach rod 2 1 slidablydisposed therethrough. The reach rod 24 is provided with a shoulder 26 formed intermediately thereon against which a coil spring is engaged, the spring 25 being disposed about the rounded portion of a reach rod 24 and engaged at its outer end against the loop 13 to resiliently hold the arm 23 against the end of the rod 24. A pin 27 is secured through the extremity of the reach rod 21 for the purpose of retaining the loop 13 thereon. The stand 19 is mounted at one side of the main track adj acent'the outer extremity of the draw bar 15 and is disclosed in the drawings as being secured to one of the ties 12 although any other suitable mounting may be employed. Spaced at a distance from the stand 19 and preferably mounted upon the extension of one of the ties 12 is a post 28 which is extended vertically from a suitably formed base plate secured to the tie 12 in any suitable manner. An operating lever 29 is pivotally mounted upon the upper end of the post 28 at an intermediate point on the lever, the inner end of the lever 29 being pivotally connected to the outer extremity of the reach rod 24. The outer end of the reach rod 24 is flattened and curved inwardly so as to engage about the upper end of the post 28 and the lever 29 when the operating lever 29 is swung inwardly against the reach rod 24.

Intermediately disposed upon the reach rod 2 1 is a pair of spring arms 30 which are provided with shoulders 31 for engagement against the outer edge of the lever 29 when the same is thrown inwardly in order to retain the lever 29 in a locked position. The

spring arms 30 are flared outwardly at their outer ends to form lips 36 '-for engaging against the opposite faces of the operating lever 29 to separatethe springs 30 and to thereby permit the lever 29 to engage with the shoulders 31. The lips 36 are apertured for the reception of a suitable padlock 32 as is disclosed in Fig. 1 of the drawings. For the purpose of adding momentum to the operating lever 29 when thrown inwardly the same is provided with a weight 33 on its outer end which is preferably integrally formed therewith by enlarging the end of the lever 29. I

In order to fric'tionally retain the operating lever 29 in "a closed position, a leaf spring 34 is fmounted upon one side of the post '28 and is extended upwardly from an intermediate point of "the post 28 th'e'spring's being curved outwardly from the post "at its upper end to engage against the inner end o'fthe operating lever 29 and to'thereby hold it under'the tension of the'spring. The spring 34 also serves the function of a stop for limiting the outward movement "of the lever 29 to prevent passing of the point of pivotal contact between'the lever 29 and the reach rod 24 bey0n'd the pivotal point of the lever 29 to the post 28. v

In order to insure the rigidity of the stand 19 and thepost 2'8 and to prevent the same from spreading and contracting, a brace is employed which is composed of a pair of icompan'ion'straps 37 "and 3 8 flanged oppositely at their ends as at 39, which flanges 39 are secured to the stand 19'and post'28 adjacentone'another. The'straps 37 and 38 are diverged intermediately'and provided with a block 40 for strengtheningthe same, the block being engaged between the straps 3 7 and 38 and secured in such position by a rivet or the like.

N ormallythe switch is retained in a closed position by securing -the operating lever 29 between the spring arms 30 and against the shoulders31. When it is desired to'open the siding the spring arms 30 are disengaged a-ndthe operating lever 29 is drawn outwardly forcing the reach rod24 backwardly through the-eye 13 against the tension of the spring 25, the strength of the spring '25 being suflicient l1 owever, to swing the arm 23 and to cause 'the rotation of "the shaft 20. This motion is communicated to the draw bar 15 through the 21 and the 22 whereby the switch points 16 and 17 are thrown into an open position "to permit a train to move from the inaintrack-onto the siding. In order to effect this result it is necessary to '-swing the lever '29 entirely around to strike'against the leaf spring 34:

thereby'properly seating the point 16 against the main rail -l0'and distancing the point 17 sufficiently clear of the oppositemain "rail 11.

The point 28 is so located from the main track that it is necessary to swing the lever 29 "against the spring 34: otherwise the lever will be in a position to be struck by the passtrain and the switch will be automatically closed. From the disclosure in the drawings it will be observed that thespring 25 will not permit the lever 29 to rest against the spring '34'but will immediately upon the release of the lever 29 from the hand of the operator, swing the lever a distance inwardly in the path of the main track thereby auto ina'tically setting the switch mechanism to be operated upon by the next passing train. This feature is an 7 advantage where the switch is left open through carelessness or by accident the loo-king means fails to retain the lever 29 is a closed position, thus insuring the safe "passage of the train over themain track.
