The drawing illustrates a main track and a siding or branch track, the former coinprist'ra'clr rail sections 1, 2 and the part '3 of the track rail section 4. The track rail section 1 is shifta hle. The siding or branch track' comprises an inclined shiftahle track rail sec; tion 5 and the inclined part 6 of track rail section 4:. One end of the section 1 provides a switch point 7 which when it abuts the part 6' of track rail section 4 fornisa continuation of the part 3 of section 4. One end of the track rail section 5 provides switch point 8 which is adapted to coa ct with the track rail section 2, when switch" point 8' is shifted to provide in connection with the part 6 a siding or branch for a train to pass froin'the siding or branch onto the main track or for passing from the main track onto thesidiag o'r'branc-h. The ties or sleepers for the track sections"are'indicated at 9 and certain of tlie'nr which a're designated 10' are of greater length than the other ties or sleepers 9. The ties or sleepers 10 project a substantial distance from the part 6 of the track rail 1 and support the housing carrying a mechanism for shifting and locking a switch point or tongue and for shifting a signal to the desired position. The switch point 7 is connected to the switch point 8 by a coupling bar 11 which has its ends fixedly secured to the inner faces of said points. The coupling bar 11 provides for the switch points to shift in unison. Projecting from the coupling bar 11 is an apertured extension 12 having one end of the throw rod 13 fixedly connected therewith. The throw rod 13 passes below the part 6 of the rail section a and below the rail section 1. A retaining rod 14 is coupled to switch points 7 8 at the free ends thereof. Angles 15 and holdfast devices 16 are employed for fixedly securing the retaining rod 141 to the switch points 7, 8. The throw rod 13 and retaining rod 1 1 are disposed transversely with respect to the main track and retaining rod 1% passes below part 8 of rail section 1 and below rail section 2. The throw rod 13 and retaining rod 11 form elements of the switch stand in accordance with this invention.

The switch stand includes a housing comprisin an open bottom body portion or cover 17 of the desired height and which seats upon a bottom forming member 18 provided with a rib 19 which is spaced from the edge of member 17. The rib 19 is vertically disposed. The member 18 is of rectangular contour and includes means in the form of spaced laterally extending apertured lugs 20 for the passage of holdfast devices to anchor such member to the sleepers 10 adjacent one side of the railway track. The member 18, centrally at one side thereof, that is, its inner side, is formed with a triangular shaped extension 21. The member 18 centrally thereof is formed with a rectangular opening 22. The rib 19 at each end of member 18 is cut away to provide a groove 23 which will be presently referred to. The bottom of the body portion or cover 17 is formed with an outwardly directed flange 24: which seats upon the upper face of rib 19. The ends of the body portion or cover 17 are formed with cutouts 25 providing openings registering with the groove 23. The purpose of the openings provided by the cutouts and grooves will be presently referred to. Formed integral with the upper face of member 18 between its transverse median and each end is a rectangular projection constituting a guide. The projections are indicated at 26, 27, the former provided with grooves 28, 29 and the latter with grooves 30, 31. The purpose of the grooves 28, 29, 30 and 31 will be presently referred to. Mounted upon the projections 26, 27, as well as being secured therewith are retaining plates 32, 33 respectively. Holdfast devices 3 1 are employed for securing the plates 32, 33 in position. The

projections 26, 27 are disposed transversely with respect to the member 18 and the grooves 28, 29, 30 a d 31 are disposed transversely of the projeceions. The grooves 28 and 30 are arranged in alignment. The grooves 29 and 31 are arranged in alignment. The grooves 28 and 30 are arranged in alignment with the openings provided by the cutout portions 25 of the body portion or cover 17 of the housing.

Formed integral with the upper face of the member 18, at one side and at the transverse median thereof is a grooved support 35 which in connection with a cap member 36 pro vides a bea ring for the purpose to be 1 resently referred to. The cap member 36 is secured to the support 35 by holdtast devices The cap member is formed with a semi-circular groove and which opposes the semi-circular groove formed at the top oi the support The groove in th cap member is designated and that in the support The support 35 and ap member 36 provide a bearing.

Rotatal mounted in the bearing provided by the support 35 and capmember 36 is the operating shaft 11 and the latter projects outwardly and inwardly from the bearing referred to. The shaft ll is disposed transversely oi? member 18. Collars 4-2, 13 and a l are carried by the shaft 41-1. The shaft 4.1 is provided with pair of crank arms 15, 46 disposed at right angles with respect to each other. The outer end of the arm 15 is formed with a yoke 47 which is offset with respect to such end. The outer end of the arm 16 is provided with a yoke 48 which is ol'lsct with respect to such end. The collar 1 1 is interposed between the inner c .d of the arm 15 L t M 1 i on and the support on and cap member 00. The

collar 13 is interposed between the inner end oi the arm 16 and. the inner end of the arm 15. The collar is is positioned against the inner end of arm 16, and is retai cd in position by a cotter pin 19. Journals-d in the yoke 47 of the arm is a roller 50 and journaled in the yolre 48 of the arm 4:6 is a roller 51. The purpose of the roll rs 50, 51 will be presently refered to. That portion of the shaft 11 which projects beyond the body por tion or cover 17 of the housing is squared and extends through the inner end 52 of an operating lever The lever is so connected to shaft 11 whereby the shaft cannot turn relatively to the lever or the lever relatively to the shaft. A securing nut is mounted on the outer end of shaft 11 and such nut is indicated at The outer end of the lever carries a counterweight 5 1.

The switch stand includes a locking element mounted for shifting in opposite directions lengthwise with respect to the bottom member 18. The locking element comprises a bar 56 standing on its lower longitudinal edge and of rectangular contour in vertical section. The bar is positioned in the end portion 66 inte ral with the other side 0 rooves 23 28 and 30. The bar 56 in roX- imity to one end thereof is formed Wlbll a notch 57 of the desired width and height and which opens at the bottom edge 58 of the bar 56. The bar 56 has as an lntegral part ther of a depending U-shaped portion 59 prov1ding a recess Intermediate the ends of the bar 56 it is formed with a cutout havin b the ed es thereof Dl'OVlClill continuations of O .1 t3 the inner edge the depei ng ti -shaped part Formed integral \Vltll the bar 56 at the top thereof is a skeleton extension or link 001113115111 an inverted iE-saaoed too n7 c: n 1 f 1 1 part o1 forming a recess 52, a curw o. sine p 63 which extends from one side of e part 6 side part consisting of an liiClllV 3(' part'6l, a forwardly xtending downwardly inclined intermediate portion 67 and a curved lower portion 68 which merges into the top of the bar 56 and is oppositely curved with respect to the portion 66. The roller is positioned to rile against the inner edge of the skeleton extension or ling iil'll. also to engage in the recesses and 62 and the purpose therefor will be presently referred to.

The switch stand further includes a throwing element consisting of a bar 69 shorter in length than the bar 56 and standing on its lower longitudinal edge. The bar 69 has a depending U-shaped strap-like part 70 which provides a recess 72. The bar 69 also is formed with a cutout 7 3 having its edges forming continuations of the inner edge of the part 70. Formed integral with the top edge of bar 69 is an upstanding link 73 which gradually increases in widthfrom its lower to its upper end and has its inner edge formed of continuations of the edges of the cutout 73. he roller 51 carried by the arm 46 is adapted to ride against the inner edge of-link 7 3 and enter recess 72 and the purpose thereof will be presently referred to. The bar 69 is mounted in the grooves 29, 31. The bar 69 is furt iermore provided with a right angularly disposed yoke-shaped lateral extension 7 1 carrying centrally of its outer end a head ed pin or stud 75. The function of the headed pin or stud 75 will be presently referred to.

The part 59 of the locking element and the part 7 O of the throwing element depend through the opening 22 in member 18. The opening 22 is of a size to provide the necessary clearance for the shifting of the locking and throwing elements lengthwise of the bottom member 18 when such elements are opernected thereto, and in connection with a lever arm 79 carried thereby the throwing of a switchpoint simultaneously with the setting of the signal.

The shaft 77 extends abovethe body portion or cover 17 of the housing and depends below the sleeve 76. The lever arm 79 is arranged on shaft 77 at the lower end thereof and is provided with pair of openings 80, 81 at the end thereof. Fixedtothe shaft 77 and bearing against the upper end of the sleeve 76 is a crank arm 82 having 'a bifurcated outer portion 83 for straddling the headed pin or stud 75. Thelever arm 9'is adaptedto be pivotally connected, as at'84fto the throw rod 12. Onlyone of the openings of thelev'er arm 79 is employed, depending on which way it. is desired to throw the switch points. The lever arm 79 conn'ected'by the opening and pivot 84 to the yokegshap'ed inner end 85 of the throw rod 12. The upper end of the shaft 77 is provided with means, as indicated at 86 for detachably connecting the signal 78 therewith.

The retaining-rod 1 1 in pro'XiInity to one end thereof is provided with a pair of spaced notches 87, 88 of the desired depth and width and which open at the top edge of rod 1 4. The notches 87, 88 associate with the bar 56 of the locking element. The notch '87 in the bar '56 associates with the retaining rod 14:. I w

The retaining rod 14 has its outer end supported and guided in a grooved casting 89 which is integral with and projects from one end of'the bottom member 18.

The bar 56 not only shifts lengthwise with respect to the bottom member 18, but the throwing element coacts with th'e shaft 77 and lever arm 79 for the purpose of throwing the switch points and shifting thesignal to the desired position. The shifting of the signal is had simultaneously with the throwing or shifting of the switch points.

It will be assumedthat the switch is normal and locked and when in such position provides for trains to travel over theroute provided by the switch point 7 on the track rail section 2. The retaining rod cannot slide in the casting 89 because it is prevented from so doing asone end of the bar 56 is'eitended through notch 87 of lock rod 14:. \Vhen lock rod 14 is arranged relatively to the locking element in the manner just referred to switch points 7 and 8 are in locked position, hen the lock rod 14 is in the position just referred to the lever 53, locking element and throwing element are in a position as shown in Figure 6. It will be assumed that the lever 53 is thrown from the position shown in Figure 6 to the position shown in Figure 7. As the lever 53 moves into the position shown in Figure 6 the crank arm 45 moves the locking element in the direction of the arrow shown in Figure 7, the roller slips out of cavity 62 and the roller 51 of the crank arm 46 rides along the inner surface of link 73, but up to this time the throwing element has not been moved. The roller 50 slips from cavity 62 and the locking element moves just enough to cause notch 57 to be in such position to allow the retaining rod 14 to pass through such notch. On a continuous shift of lever 53, crank arm 45 will cause roller 50 to ride clownwardly against part 63 of the extension or link of the locking element, without moving the latter, but the crank arm 46 will cause roller 51 to rotate in cavity 72 of the throwing element for moving the latter in the direction of the arrow shown in Figure 8. \Vhen the throwing element moves in the direction of the arrow in Figure 8 the stud 75 on the lateral extension 7 L will slide in the bifurcated end of crank arm 82 thereby turning shaft 77. When shaft 77 turns, the lever ar 79 will be carried therewith and the switch points 7, 8 will be shifted from the position shown in Figure 1 to a position whereby the switch point 8 will abut the track rail section 2 thereby providing for a train to travel along the main track onto the branch or siding or from the branch or siding onto the main track. When the shaft 77 is turned it will also provide for the shifting of the signal or target 78. The switch is now reversed but not locked, however, the retaining rod le is moved over so that its notch 88 is directly in line with the end of bar 56. Now lever 53 is turned downward until it takes the position shown in Figure 9 and the roller 51 will ride against link 73, but will not shift the throwing element, but the roller 50 is now located in the recess of cavity and moves the locking element in the direction shown by the arrow in Figure 9, so that notch 57 is not located to allow movement of the retaining rod 14, thus the switch is now locked in a reversed position.

The locking element, in connection with the crank arm l5 provides means for locking the switch in a position to which it has been fixed.

It is thought that the many advantages of a switch stand, in accordance with this invention and for the purpose set forth can'be readily understood, and although the preferred embodiments of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which fall within the scope of the invention as claimed.
