SWITCH-STAND CRANK MECHANISM.

Specification of Letters Patent.

Patented Jan. 25, 1916.

Application filed August 7, 1915. Serial 0. 44,165.

To all whom it may concern.

Be it known that I, FRANK C. ANDERSON, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Switch- Stand Crank Mechanism, of which the following is a specification.

My invention relates to switch stands; and its object is to render the switch stand interchangeable for use on either the right or left hand side of the track, and for a turnout in either direction, whereby it may be locked over the front head-block in any of these installations, i. e.locked on the side of approach into the turnout, thus permitting more uniformity and convenience in general, in the installation and operation of switches.

lVith the above purposes in view my in vention consists in the improved crank and crank mechanism hereinafter set forth and claimed.

Inthe drawing: Figure 1 is a plan view of a switch stand with my improved crank mechanism applied thereto; Fig. 2 is a front elevation of the same; Fig. 3 is a vertical sectional side elevation of the same, the section being taken on a line corresponding to the line w-zv of Fig. 2; Fig. 4c is a detail perspective view of the crank; Fig. 5 is a view similar to Fig. 3, showing a modifica tion; and Fig. 6 is a detail perspective view of the modified head.

The switch stand here shown to exemplify the use of my invention comprises the frame 1 with the top plate 2, which has the two notches 8 and 1, 180 apart and adapted to be alined substantially parallel with the track rail and having a backward extension 5 with a third notch 6 midway between or 90 from the other two notches 3 and 4 and opening outwardly at right angles to the track rail. A shaft 7 is j ournaled vertically in the frame 1 and has a fulcrum head 8 fixed upon it to swing around over the top plate 2, while this fulcrum head 8 has a' substantially L-sh'aped in this respect.

around, turning the shaft 7 with it. As here shown, the shaft is rotated through an angle of 180 to throw the switch.

The connecting rod 10 extends from the crankof the switch stand over toward the track between the

head blocks

11 and 12, to which the feet 13 and 1 1 of the framel are secured, and is connected with the point rails in a well known manner. In order that the switclroperating lever 9 may have closed the switch when it has dropped into the notch 3 or 4, depending upon whichever side the switch turns out upon, it is necessary to pro vide for two difi'erent adjustments of the crank with respect to the shaft 7 and, since the switch stand may be located on one or the other side of the track, it is necessary to provide two adjustments for this reason in connection with either one of the above reasons. It is highly desirable that it be possible to order any quantity of the switch stands and use them in any one of the four positions demanded in the service. It is in the crank of the switch stand that I provide means for enabling the above convenience to be attained. I accomplish this purpose by providing the lower end of the shaft 7 with a substantially rectangular head 15 which has openings 16 through it horizontally at right angles to each other. The head 15 may be forged on the end of the shaft 7 and the openings 16 may be bored therethrough.

The crank 17 comprises a head 18 with an upright part19 and a horizontal part 20 extending in one direction from. the bottom of the part 19 so that this head 18 is thus It has a rib 21 that braces the two

parts

19 and 20 with respect to each other. Projecting down from the bottom of the lower horizontal part 20 is the crank pin 22 having on its lower end a flat head 23. Projecting from the side of the upright part 19 in direction opposite from the projection of the lower part 9.0 is a shank 2d which is adapted to fit into and extend through either one of the horizontal openings 16 through the head 15 of the shaft 7. Also projecting from the head 18 inthe direction of the shank 2 1 but at the'bottom opposite from the part 20is a lip 25 that will come snugly under the lower side of the shaft head 15. The shank 24 is threaded for a considerable distance number of washers 29 may be interposed, as

shown in Figs. 1 and 3. I The connecting rod 10 has a erotchy30 on its end to fit up against a side of the crank pin 22 between the lower side of the crank head 18 and the head 23 of the crank pin 22 and when the rod 10 is in this position a U-shaped strap 31 ispassed over the crank pin 22 with its side parts flanking the rod 10 near itsend, and bolts 32 are passed through openings in the side parts of the strap 31 and through the rod 10, as shown in Fig. 3, holding the strap rigidly to the rod. Thus the bearing of the connecting rod 10 on the crank pin 22 is made up of the crotch 30 and the part of the strap 31 that extends around the otherside of the'crank pin, as is best seen in Fig. 1. I

The entire crank comprising the head 18, with its two parts 19 and-2O and. rib 21 and the crank pin 22 with its head 23 and'the shank 24: and the lip 25 are all formed integrally of cast steel or of a steel forging.

The purpose of the lip 25 engaging with the lower side of the shaft head 15 is to prevent turning of the crank in the opening 16 in which it is inserted. From the foregoing it will be seen that the crank 17 may be made to have four different positions with respect to the shaft 7 by inserting the shank 24 through either one of the openings 16 in either direction. Furthermore, when the washers 29 are interposed between the nut 26 and the shaft head 15 the radius of the crank may be very readily adjusted by transferring one ormore of these washers 29 to the other side of the shaft head 15 between it and the crank head 18. Thus adjustment of the radius or throw of the crank may be .made to compensate for wear or to make the switch stand suitable for dilferent switches having the point rails thrown dif ferent distances.

Whlle thus providing for ready adjustment for the purposes hereinbefore pointed out, and also for ready adjustment of the throw of the crank when the washers are used, there is,'nowhere, in the construction of thecrank on its fastening to the shaft 7 any part that is liable to become loose and allow the parts to become detached and inoperative. Therefore, while affording great convenience, there is also afforded a high degree of safety and efliciency in this important part of a switch stand.

In the modification shown in Fig. 5, the

ing example, with the advantage of dispensing with the need of finishing the shank in behind the lip 25", offsetting the disadvantage of having the crank made thus in two pieces; and atthe same time, all of the advantages of adjusting for difie'rent positions and of adjusting the radium or throw of the crank are available as with the device of the precedingexample.

Although I show my invention applied tov a switch stand for operation through an angle of 180, it will be understood that it is equally suitable for operation through only as whenthe lever. 9 occupies the intermediate notch 6 in open position.
