*CHARLES W. REINOEHL, OF STEELTON, AND MALCOLM W. LONG, OF HARRISBURG, PENNSYLVANIA.

SWITCH-STAND.

T all whom t 'may concern.'

Be it known that we, CHARLES lV. Rin- ;tonnL, a citizen of the United States, and resident of Steelton, Dauphin county, State of Pennsylvania, and MALCOLM W. LONG, a citizen of the United States, and resident of Harrisburg, Dauphin county, State of Pennsylvania, have invented certain new and useful Improvements in Switch-Stands, of which the following is a specification.

This invention relates to switch stands for railroad switches.

The object of the invention is to provide a switch stand combining simplicity of construction with ease and efficiency of operation, whereby the tongue of a railroad switch may be easily adjusted by hand to either of its two positions, and whereby the switch tongue may be firmly yet yi eldingly held in either of its two positions until it is moved therefrom by an excess of a predetermined pressure against the tongue by the action of a car wheel in opening or closing the switch when passing the tongue in a direction from the heel to the point end thereof.

Having thisy object in view, the invention consists in the novel construction and combinations of arts hereinafter fully described and claimed.

In the drawings Figure 1 is a plan view of a railroad switch stand embodying our invention. Fig. 2 is a vertical section thereof, as on the line 2 2 of Fig. l. Fig. 3 is a horizontal section, as on the line 3-3 of Fig. 2. Fig. 4 is a bottom view of the upper clutch member and lever support, detached. Fig. 5 is a horizontal section as on the line 5-5 of Fig. 2.

The main fra-me or support of the switch stand comprises a base 6, and a hollow standard 7 yrising therefrom, provided with lateral strengthening ribs 8. rFhe base 6 is provided with suitable spike-receiving holes 6a as a means for securing the frame or support to the cross ties adjacent a railroad switch.

Vithin the lower portion of the hollow standard 7 are two centrally-disposed, vertically-arranged bearings 9 and 10, located one above the other, as shown. In the present embodiment of our invention, these bearings are cast integral with the main support 7. Fitted to the bearing 10 is a lower vertical shaft 11, and tted to the bearing 9 is an upper vertical shaft l2, which extends up Specification of Letters Patent.

Application filed September 11, 1908.

Serial No. 452,531.

' through the standard in line with the lower shaft l1 and forms in effect a continuation thereof. .Secured to the upper end of the shaft 11 is a collar 13, provided with lateral arms 14, and secured to the lower end of the shaft 12 is a collar l5 provided with lateral arms 16 which are arranged in the same horizontal plane with and adjacent to the arms 14. The arms 111 are provided with adjustable screws 17, which are adapted to abut against the arms 16 and thereby cause the shafts 11 and 12 to turn as a unit and at the same time provide a means whereby one shaft may be adjusted with relation to the other, circularly about the axes thereof. This adjustment is accomplished by adjusting one of the screws 17 toward its adjacent arm 16 while the other screw 17 is adjusted away from its adjacent arm 16. The lower end of the shaft 11 extends below the bearing 10 and has secured thereto collar 18 which is provided with laterally extending crank arms 19. Each crank arm 19 carries a vertical pin 20, and connected to one pin 20 is one end of an arm 21, the other end of which is adapted to be connected to the tongue of. a railroad switch in the usual well known manner.

Located at the top of the standard 7 and mounted on the shaft l2, is a clutch member 22, comprising a central collar 23 rotatably fitted to the shaft 12, a cam flange 2% extending downwardly into the standard 7, and a horizontal flange 25 resting upon the top of the standard 7 and projecting beyond the outer edge thereof. The bottom of the cam flange 24 is provided with a cam surface having four equidistant depressions or retaining portions 26, the cam surface of each depression terminating upon meeting the cam surface of the two adjacent depressions, thus providing the intermediate cam projections 27. i

Located directly beneath the clutch member 22 is another clutch member 2S, which surrounds the shaft 12 and is slidingly fitted thereto to permit its movement toward and from the clutch member 22 longitudinally of the shaft 12. The lower clutch member 28 is not only guided by the shaft l2 in its movement toward and from the member 23, but it is also guided by lateral, vertically-arranged guide-bars 29, which are formed on the member 28 and fitted to vertical guide-ways 30 formed in the support or standard 7. The

engagement of the guide-bars 29 with the walls of the guide-ways 30 also prevents rotation of the member 28 about the shaft 12.

rl`he lower clutch member 28 is provided with parts adapted to engage and coact wit-h the lower or cam surface of the flange 24 forming the depressions 26 and intermediate projections 27, and in the present embodiment of our invention these part-s of the lower clutch member coacting with the cam surfaces of the upper clutch member are anti-friction rollers 31, two in number, and rotatably mounted on pins 3s projecting from opposite sides of the member 28 in line with each other, whereby the two rollers 31 will engage two opposite depressions 2G of the member 22, and when the member 22 is given a quarter turn relatively to the member 28, the rollers 31 will be brought into engagement with the other two opposite depressions 26, as will be hereinafter explained. rl`he parts or rollers 31 of the lower clutch member 28 are forced into engagement with the upper clutch member 22 by the action of spring 33 encircling the shaft 12 and having its lower end bea-ring against the top of the bearing 9 and its upper end bearing against the bottom of the lower clutch member 2S. Thevertical movement of the upper clutch member 22 under the influence of the spring 33, is prevented by a collar 3d secured to the shaft 12 directly above the upper clutch member 22. The collar 341- forms a partof a lever support which extends laterally from the shaft 12 and has pivotally connected thereto, as at 86, a locking lever 37, which may be moved on the pivot 36 either to the full line or to the dotted line position shown in Fig. 2. Nhen the lever 37 is lowered to the full line position shown in Fig. 2, it extends into vone of four equidistant lever-receiving notches 38, which are formed in the outer portion of the liange 25 of the upper clutch member 22, one notch 38 being located adjacent each cam depression 2G. When the lever 37 is in the lowered or full line positionextendino through one of the notches 38, the sides of the lever engage the side walls of the notch and thus loci; the lever 37, its support 35, and the upper clutch member 22 and shaft 12 together, to cause them to turn as a unit. lVhen, however, `the lever 37 is raised to the dotted line position it is disengaged fro-m the upper clutch meinber 22, and it may then be turned to turn the lever support 35 and the shaft 12 xed thereto independently of the upper clutch member 22, and also independently of the lower clutch member 28, for a purpose hereinafter explained. The lever 37 may be locked in the lowered or full line position by inserting a pin 39 into an opening Ll() in the lever 37, the pin 89 being adapted to engage a projection 41 on the lever support 35 and prevent the raising of the lever 37.

ln the drawings, the top of the shaft 12 is shown broken away. This shaft is adapted to extend a suitable height and constitute the target shaft for the reception of a target` signal which will thereby be adjusted with the switch to indicate its open or closed posi tion.

It will be observed, on reference to Fig. 2, thatthe top of one of the ribs S terminates in a step by means of which the target signal upon the top of the shaft 12 may be reached.

Vlhe operation is as follows i/@then the switch stand is in position to operate or be operated by a railroad switch, the base 6 is secured to the cross ties adjacent the switch, and the connecting bar 12 isv connected to the tongue of the switch at substantially right angles thereto. ln this position of the parts he switch tongue is held in either its position against the main rail or its position away from the main rail, by its connection to the shaft 12 and the shaft 12 being held lirmly in position by the engagement of the rollers 31 of the clutch member 2S with two opposite depressions or retaining portions 2e of ythe upper clutch member 22. lf, in this position of the parts, a car wheel passes the switch in the direction from the heel to the point of the switch tongue, and the switch is not properly set to receive the wheel, the flange of the wheel exerts suflicient lateral pressure against the switch tongue to cause it to turn the shafts 11 and 12 a quarter revolution, thus overcoming the action of the spring and causing the cam projections 27 of the upper clutch mem` ber to force the rollers 31 and lower clutch member 2S downwardly against the action of the spring 33 until the apexes of the cam projections 27 pass the rollers 31, whereupon the rollers 3l will leave two opposite depressions 26 and be forced into the other two opposite depressions 26 to retain the switch tongue in the other position to which it is moved by the car wheel flange. lllhen, however, it is desired to operate the switch stand by hand to move the switch tongue to either of its two positions, the lever 37 is raised to the position shown by dotted lines, thus unlocking the upper clutch member 22 from the shaft 12, and leaving the shafts 12 and 11 free to be operated by the hand lever 37 to adjust the switch -as desired. By adjusting the screws 17, the shaft 11 may be adjusted with respect to the shaft 12, to properly setthe switch tongue with relation to the main rail, and the clutch -members 22 and 2S.

Having thus described our invention, we claim l. In a switch stand, the combination of a support, a rotatable shaft, means to connect the shaft with a switch tongue, two clutch members mounted on the shaft one member having a movement toward and from the other member longitudinally of the shaft and one member having a cam sur` face coacting with a part of the other member, a spring acting to press one member' into engagement with the other member, means to prevent rotation of one of said members about said shaft, and means for locking the other member to and unlocking it from said shaft.
