RAILWAY-SWITCH.

Specification of Letters Patent.

Patented June 22, 1909.

Application led July 20, 1908. Serial No. 444,538.

To all whom it may concern:

Be it known that we, CHARLES W. Rm- NOEHL and MALCOLM W. LONG, citizens of the United States, said REINOEHL residing State of Pennsylvania, and said LONG residing at Harrisburg, Dauphin county, State of Pennsylvania, have invented certain new and useful mprovements in Railway-Switches, of which the following is a full, scription, reference panying drawings.

Our invention relates to railroad switches, the object being to provide a simple, durable, and eflicient means which may be set to maintain the switch tongue of a railway switch yielding y in one of its two positions, and automatically return it to such position after being moved therefrom; which may be clear, and exact debeing had to the accomset to maintain the switch tongue yieldingly in its other position, and automatically return it to said other position after being moved therefrom; and which may be set to maintain the switch tongue yieldingl)T in either of the two positions to which it may be adjusted.

The invention consists in the novel features of construction and combinations of parts which we shall hereinafter fully describe and claim.

In the drawings z-Figure 1 is a plan view of al railway switch section provided with our invention. Fig. 2 is a vertical section, as on the line 2-2, of Fig. 5, including the cover for the casing. Fig. 3 is a vertical section, as on the line 8-3 of `Eig. 5, including the cover for the casing. Fig. 4' is a bottom view of the adjustable head for setting the spring actuated mechanism. l? ig. 5 is a plan view of the box or casing containing the spring actuated mechanism, showing the parts set in position to maintain the switch tongue yieldingly in one of its two positions, and automatically return it to such position after being moved therefrom; the cover for the box being removed. Fig. 6 is a view similar to Fig. 5, showing the parts set in position to maintain the switch tongue yieldingly in the other position, and automatically return it to said other position after being moved therefrom. Fig. 7 is a view similar to Fig. 5, showing the parts set in position to maintain the switch tongue yieldingly in either of the two positions to which it maybe adjusted.

4 is a railway switch section, including the tongue 5, the heel end of which is pivoted as at 6, and the side walls 7 and 8 between which the tongue 5 is arranged. 9 and 10 are the rails leading from the heel end of the switch, and 11, the rail leading from the point end of the switch. The tongue 5 is movable laterally into engagement with either the wall 7 or the wall 8; and when it is in engagement with the wall 7, car wheels are directed thereby between the rails 10 and 11, and when it is in engagement with the wall 8, car wheels are directed thereby bctween the

rails

9 and 11.

Secured to one side of the switch section 4, is a box or casing 12, provided with a suitable cover 13. Extending through a stufling box 14 in the wall of the casing 12, is a rod 15, one end of which extends through an opening in the switch section 4 below the switch tongue 5, and is secured to a lug 16 projecting downwardly from the switch tongue 5. Theother end of the rod 15 within the casing 12 is screw-threaded, and screwed into a boss 17 on a plate 18 which extends over one end of a plate 19 resting upon the bottom of the casing 12. The plate 1S is provided with a longitudinal slot 20, therein, through which extends a pin 21, rising from the underlying plate 19.

The pin 21 projects above the top of the plate 1S and is provided with a collar 22 adapted to engage the top of the plate 18. A cotter pin 23 extends through the collar 22 and pin 21, to hold the collar 22 in the position just mentioned. The width of the end portions of the slot 2() is e ual to the diameter of the pin 21, and said wz s of the center portion of the slot 2O are expanded, as at 24, to receive and lit the collar 22, which may be adjusted into the expanded portion 24, for a pur )ose hereinafter explained.

Tie plate 19 is pivotally connected, as at 25, to one end of a lever 2G, which, is rotatably mounted on a pin 27 screwed into a boss on the bottom of the casing 12, and rising therefrom. The other end of the lever 26 is provided with a roller 28 which is engaged by a V-shaped cam 29 projecting centrally from a bar 3() toward the pivot pin 27 of the lever 26. The lower ortion of the cam 29 is provided with a gui e-block 31 arranged between two ribs 32 on the bottom of the casing 12 and forming a guide-way to direct the cam 29 toward and from the pin vpressure moving theswitch tongue 5 is -rethe head 38 to maintain the head jgagement with vthe wall 8.

lto return the switch tongue;

V,abar

27 of the lever 26. The ends of the bar 30 are rovided withy ins 33iwhichproject paralle to the guide-b ocks 31 and through-perforations in lugs 34 on the casing 12. The projecting ends of the pins 33 are .provided with heads between which and the lugs 34 are finterposed.l springs. 36 which encircle the ins 33 and force said pins and therewith the bar 30 and the V-shaped cam 29 normally toward the pivot pin 27 of the lever 26.

Seated in a'depression 37 in the cover' 13, is a head 38 which is rotatably mounted on the' pin 27. -The upper endl of the pin 27 is provided with a nut 39 :which engages a washer in the bottom of a'depression 40 in 38 in position within the depression 37. The head 38 'isprovided with a downwardly extending boss 41 the bottom of which is arranged just above the top of the lever-26.

YThe bottom of the boss 41 is provided with two teeth 42 which are arrangedin the same horizontal plane with and between two teeth 43 projecting upwardly lfrom the top of the ever-26, whereby vthe head 38 may be turned to. cause the teeth 42 to engage the teeth 43 =,and turn or adjust vthe lever 26 for a purpose hereinafter explained. The head 38 is provided wi'th suitable radially-arranged slots 44 into'which any suitable tool or bar may be inserted for the purpose of turning the head38.

The operation is as followsz-VVh'en it is 'desired to` maintain the switch tongue 5 vyieldingly against the wall 8,.and to automatically return itrto said position after being moved therefrom, the parts are set in the position shownin: Figs. 1,2, 3,-and' 5.

YIn this position of the parts, .the Y-shaped cam 29 is acting upon the roller 28 and lever 26 to' force the plate 19in a direction away from the switch section 4, thuscausing the pin-21 to engage one end of `the .slot-20 and act upon the plate 18 and rod 15 in a manner to draw the switch tongue 5 over-into en- Should the switch tongue 5 be moved from its position against the vwall 8, against the. action of the springs 36, the roller 28 will not pass over the point of the cam. 29 therefore, when'fthe moved, the eam29'will act upon 'the lever 26 to its position against the-wall 8. When `it is 'desired to maintain the switch rtongue 5 yieldingly in its otherposition, inengagement with the wall 7, and to automatically return it to said other position after being moved therefrom, or other suitable tool, isinserted in one of the slots 44in the head 38, and the' head 38 is turned tocause the teeth 42 thereof to .engage Vthe teeth' 4310i `the'lever 26 and turn the l ever4 to move' its roller 28 `past the point of 'thefY-'shaped caml 29 against the action of the springs 36, and Vinto engagel ment with the other side of said cam, as l shown ,inyFig. 6. This adjustment ofi the leve1126 moves the pin 21 through the slot 20 and into engagement with the other end thereof, and acts upon the plate 18 and therej with the rod 15, in a manner to force the switch tongue 5 over into engagementwith .the wall 7 in which position it is held yieldingly by the action of the cam 29 and its connectons. Should the tongue 5 be moved against the action ofthe springs 36, the roller 28 will not pass over the point ofthe cam-29; therefore, when ,the pressure moving the switch tongue 5 is'removed, the cam29 will Fig. 5 and retain the switch tongue yielding] y I in ,engagement with the walll 8,-this-may be `doneby inserting a bar or other tool Ain one of the slots 44 of the head 38,'and turning said head to adjust the-lever 26 to the position shown in Fig. 5. V] hen it is desired to Vmaintain the switch tongue 5I yieldingly-in position against either the wall 7 or the wall 8 to whichit may be adjusted, 'the lever 26 is adjusted. yupon the pin 27 to the position shown in Fig. 7, thus bringing the pin 21 to a position midway between the ends of the slot 20; whereupon, the cotter pin 23 is removed from the collar 22 and pin 21, and the collar 22 is dropped into the expanded central portion 24 of the slot 20. The cotter pin23 is then replaced within the opening in the-pin 21, above the collar 22, to retain said collar in-'its position within the expanded portion of the slot. Vtlhen the parts are in the position shown in Fig. 7, the roller 28 is very near the point of the Y-shaped cam 29, and the action of one side of the cam 29 is to force the switch tongue 5 yieldingly into engagement-with the wall 8. Should the-switch tongue 5 be moved from its position in engagement with the wall 7, the roller 28 will pass over the point of the Y-shaped cam29, against the action of the springs-36 and the other side of the cam 29will `then act upon ,the parts to hold vthe switch tongue 5 yieldingly'in engagementwith the-wall 7. Thus, each time Vthe switch tonguel 5 ismoved from 'side to side, the roller=28 will move over the point of the cam.
