SWITCH-STAN D.

SPECIFICATION forming part of Letters Patent No. 724,658, dated April 7, 1903. Application filed September 3, 1902. Serial No. 121,949. (No model.)

To all whom it may cmwern:

Be it known that I, ARTHUR B. BELLOWS, a citizen of the United States,-residin g at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Switch-Stands, of which improvements the following is a specification.

The invention described herein relates to certain improvements in switch-stands, and has for its object a construction and combination of parts whereby motion may be transmitted from a crank-arm operative in one plane to a crank-arm adapted to oscillate in a plane at right angles thereto.

It is a further object of the invention to provide for the securing of the several parts of the switch-stand in operative relation by the cover or top portion of the case or shell.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of my improved switch-box with a portion of the cover broken away. Fig. 2 is a sectional elevation on the plane indicated by the line II II, Fig. 1. Figs. 3 and 4 are sectional elevations on planes indicated, re spectively, by the lines III III and IV IV, Fig. 1. Figs. 5 and 6 are detail views.

In the practice of my invention the mechanism, except the operating-1ever, is inclosed within a case or shell consisting of a bottom portion 1, provided on opposite sides with lugs or flanges 2, to which the top or cover 3 is secured by bolts 4, said top or cover hav ing laterally-projecting flanges 5, whereby the box or case may be secured on the ends of cross-ties or other suitable foundations.

The bottom portion of the box or case isprovided with a socket 6 for the reception of a journal 7 on the lower end of the transmitting-shaft 8. The upper end of this shaft is provided with a semispherical socket for the reception of a spherical journal or ball 9 on the end of an arm 10. This socket has a portion of its side wall cut away to permit of the extension of the arm 10 therethrough, and side walls or wings 11 extend from the edges of the cut-away portion along each side of the arm, so as to afford a strong lateral bearing forthe arm during the operation of the switch.

The ball 9 is held in position in the socket of the shaft 8 by means of a cap 12, having a semispherical socket therein, the edges of said socket being formed with projections or lugs fitting into corresponding recesses formed around the edges of the socket of the shaft 8, as clearly shown in Figs. 1, 3, 4, and 5. The cap 12, which forms a continuation of the shaft 8, is provided with shoulder 13, on which the cover of the case will bear and hold the cap 12 in position onthe shaft when the cover is bolted to thelower portion of the case or shell.- The cap portion 12 is provided with a spindle 14, projecting up through the cover of the case or shell for the reception of the target 15.

The'outer end of the arm 10 is provided with a journal-pin 16, formed at an angle to the arm and fitting loosely within an opening in the crank-arm 17, formed on or secured to the driving-shaft 18, which is shown with its journal portion arranged in suitable bearings 19, formed partly in the lower portion of the case or shell and partly in the cover, as clearly shown in Fig. 4. On the outer end of this driving-shaft a notched disk 20 is secured, but may be formed integral therewith, and a lever 21, providedwith a shoulder 22, is pivotally connected to the shaft in such manner that the shoulder 22 will project into the notch in the disk, and the lever will be free to move independent of the shaft for a distance equal to the distance between the shoulders formed by notching the disk 20. By this construction the operating hand-lever 21 can have a .movement through an arc of approximately ninety degrees (90) or from a horizontal to a vertical position before the shoulder 22 will bear against the shoulders formed by notching the disk, so that no material labor is'required to raise the lever to a position in which power may be conveniently applied to shift the switch.

The shaft Sis provided with an arm 23, extending laterally therefrom and adapted to be connected to the switch-rod 24 by means of a pin 25. This pin, whose lower portion extendsinto a slot 26 in the switch-rod 24, is I00 provided with a collar 27 about midway of its length and adapted to rest upon the switchrod. The arm or extension 23 from the shaft 8 bears upon this collar and prevents the pin from jumping out while in operation.

In congregating the parts the switch-rod 24 will be first placed in position, the case or shell on the switch-rod side being divided along the plane of the axis of the rod when in position. The connected pin is then placed in position and the shaft 8 adjusted with its journal in the bearing-socket 6 and the opening in the laterally-extending arm fitting over the pin 25. The arm 10, with its journal-pin fitted in the crank-arm 17 on the driving-shaft 18, is then placed in position, as shown in Fig. 4. The cap 12 of the shaft 8 is then placed in position, inclosing the ball on the arm 10, and the cover 3 of the case bolted in position on the lower portion, thereby firmly to secure all the parts in operative relation to each other.

By reference to Fig. 2 it-will be clearly seen that the several parts are so constructed and adjusted that the crank-arm will move in shifting the switch through an arc of approximately ninety degrees, (90,) although the operating-lever moves through an arc of one hundred and eighty degrees, (180.) By this construction and arrangement the axis of the journal-pin on the arm 10 will always be below the axis orcenterof rotation of the drivingshaft 15, so that there can be no dead-point or point wherein the crank-arm cannot be shifted by force applied to the switch-rod through the running of a train through a closed switch or power otherwise applied to the switch-rails. By this construction all danger of injury to the switch operating mechanism from the train passing through a closed switch can be avoided.

While not necessary, it is preferred to employ wings 11 on the shaft 8, so as to provide a better bearing for the arm 10.

It will be observed that the radial slot or opening from the ball-socket in the shaft 8, formed in part by the wings 11, is elongated vertically, so as to permitof the vertical movement of the arm 10 when shifted by the crank-arm 17. The ball-and-socket connection between the shaft 8 and arm 10 permits not only the vertical movement of said arm, but also its axial oscillation when being shifted by the crank-arm.

It is characteristic of my improved switch mechanism that all the parts intermediate of the switch-rails and the operating-lever are held in operative relation to each other by the cover 2 of the case or shell, thereby avoiding the use of set-screws, keys, or other similar devices.
