SWITCH-STAND.

Patented July 28, 1914:.

Application filed July 19, 1912. Serial No. 710,350.

.1 0 all whom it may concern Be it known that 1, JOHN C. HOLMAN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Switch-Stands; and I do declare the following to be a full,

clear, and exact description of the inven tion, such as will enable others skilled in the artto which it appertains to make anduse the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

be run through the switch and whereby the stand and connected parts are not destroyed by such action of the locomotive or train.

In accomplishing these objects, I have provided the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure l is a persl cctive view of a railway switch and a switch stand constructed according to my invention Fig. 11 is a side elevation of the operative parts of the stand. Fig. H1 is a plan view of same. Fig. 1V is a perspective view of the body of the stand and the crank members, the crank head being removed for "better illustration. Referring more in detail to the parts :1 designates a section of main track, 2 a siding and 8 the switch points for directing a train along the main track or onto the siding. Connected with theswitch points is a bar d which extends to the side of the track and is there connected with a crank arm 5 that is fixed to the lower end of a staff 6 that is revolubly mounted in upper and lower members 77 of the switch stand 8. Also revolubly mounted in the members 7-7, and paralleling the staff 6, is a stalf 9. The staves 6 and 9 may be ordinary signal staves, in which event they will carry one a target 10and the other a signal lamp 11, although the invention is not limited to the combination of the switch stand with the signals, as it relates solely to the construction of the switch stand. I

Fixed to each of the staves 6 and 9, is a crank arm 12 which projects forwardly from the stand and carries perpendicular posts 13, each of which has a reduced, threaded part 14 at its upper end, forming an upwardly facing shoulder 15.

Revolubly mounted on the posts 13, and seating on the crank arms 12, is a crank head 16, having downwardly projecting ears 1? provided with beveledends 18 and separated by a U-shaped recess 19.

Rising fromthe center of the head 16 is a post 20 and surrounding said post is a spring 21 which is normally held under tension by a keeper-bar 22, through which the post is slidably projected, and which is fixed rigidly to the upper ends of the posts 13 by nuts, or the like, 23. v

Revolubly mounted in bearing 24, on the base member 7 of the switch stand is a shaft 25, the forward end of which carries a crank arm 26 having a forwardly directed roller 27 thereon, which is adapted for engagement with either of the oeveled ears of the crank head when the operating shaft is turned by the handle 28, which is attached to its rear end.

Presuming the parts to be constructed and assembled as described, and the switch points set forthe main track, the handle will be in the position shown in Fig. 1. Should it be desired to throw the switch for the siding, the handle isthrown to the opposite side or through a half circle, such action turning the crank arm 26 and cansing the roller 27 to engage the left-hand ear of the crank head and thereby throwing the head laterally on its mounting; WVhen the crank head is moved laterally it carries the staves 6 and Q therewith, turning same a fourth of a revolution so as to show the proper signals by the lamp and target. When the staff 6 is turned in its bearing in the switch stand it moves the crank arm 5 so that the bar a is moved outwardly toward the track to move the outer switch point toward the outsiderail, and the inner switch motive or train on the main track run through the switch when it is in this position, the switch points are forced laterally and turn the crank arm 5 and staff 6, such action moving the crank head 16 laterally so that the ear 17 rides up the roller 27 on the crank 26 until it reaches the opposite side thereof, when it is forced downwardly by the spring 21. Inasmuch as the entire movement is made by the crank head, the handle does not change its position so that the switch cannot again be thrown by the handle until the crank head is removed and readjusted. If, however, after the switch has been run through from the siding, the switch points are forced back to the original posi tion again, moving the crank head over the roller and reseating the head so that the stand may be operated in the usual manner.

With a stand of this construction, the destruction of the parts incident to the running through a switch, having an ordinary stand, is obviated.

Having thus described my invention, what I claim is new therein and desire to secure by Letters-Patent, is

1. In a switch stand, the combination with a staff having means for connection with a switch point, a point lever, and a head connected with thestaif and adapted for actuation by the lever or for riding over the lever when actuated by the stafi.

2. In a switch stand,the combination with a staff having means for connection with a switch point, a point lever, a head connected with the shaft and adapted for actuation by the lever or for riding over the lever when actuated bv the staff, and means for yieldingly tensioning said head toward the lever.

3. In a switch stand, a revoluble staff,a

point lever having a crank member thereon,

a mounting connected with the staff, a head slidably mounted on said mounting and having ears adapted to lie on opposite sides of the crank member, and means for yieldingly tensioning said head toward the crank member.

d. A switch stand comprising a lever, having a crank atone end provided with a laterally projecting member, a revoluble staff, a head connected with the staff and having a bifurcated portion overlying the member on said crank whereby the head may be moved by the handle member, or may be moved thereover when actuated by the staff, and a point lever connected with said staff.

5. The combination with a lever, having a crank member thereon, of a revoluble staff, a head connected with the staif and having ears straddling the crank member, and a point lever connected with said staff.

6. The combination with a lever, having a crank portion, of a revoluble staff, having a crank arm, a head pivotally mounted on the crank arm and having downwardly projecting ears straddling the lever crank, and a point lever connected with said staff.

a 7. The combination with a lever having a crank member, of a revoluble staff having a crank arm, a post on said arm, a head pivotally mounted on said post and adapted for lateral movement when the staff is revolved, said head having spaced ears straddling the crank member on the lever, and a point lever connected with said staff.

8. The combination with a lever, having a crank provided with a laterally directed roller, of a revoluble staff, a head connected with the staif and having downwardly projected pointed ears straddling the roller, and a point lever connected with said staff.

9. The combination with a lever having a crank member thereon, of a revoluble stafi, a head connected with the stafl and adapted for vertical movement, means Ior yieldingly tensioning the head toward one limit of its movement, ears on said head straddling the lever crank, and a point lever connected with the staif, for the purpose set forth.

10. The combination with a lever having a crank member thereon, of a revoluble staff having a crank arm, a post on said arm, a head mounted on said post and adapted for pivotal and sliding movement thereon, a bar carried by said post, a post on .the head slidably projected through the bar, a spring on said head post between the bar and head, ears on said head straddling the lever crank, and a point lever connected with the staif.

11. The combination with a lever having a crank provided with a laterally facing roller of a revoluble staif, having a crank arm, a post mounted on said arm, a head pivotally and slidably mounted on the post and having I spaced, downwardly projecting, pointed ears straddling the roller on the lever crank, a bar carried by said post, a post on the head slidably projected through the bar, a spring located between the bar and head and yieldingly retaining the latter in lowered position, and a point lever connected with the staif.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN C. HOLMAN.
