170 LEZ whom, t may concern;

Be it known that we, WILLIS C. LEE and MILES F.MOORE,citizens ofthe United States,

residing at South Chicago, a part of the cityV of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Combination Crossing and Double Slip- Switch with Movable Center Points, of which the following is a specification in its best form now known to us, reference being had to the `accompanying drawings, in. which similar characters indicate the saine parts throughout the several views.

Our invention relates to com bined railroadcrossings and slip-switches; and the object of our invention iS-to produce such mechan- I ism in' whichit is possible when it is properly set for a train to cross at different tilnes .on

either track and also by properly settingthe switchesto be transferred from either diago-` nal track to the other of said crossings.

Our invention particularly relates to lnech` anisln for controlling such `a combination crossing and double slip-switch with movable center-points by a single lever, preferably mounted in the switch-stand adjacent to the track, so that by moving this single lever to successive positions the switches on the crossl ing willbe successively set for a. crossing on one track, a slip-switch from one track to the other, a through-crossing on the other track, and the use of the opposite slip-switch.

Our invention also consists in the colnbi-` nation, with the above, of a system of signals sage of trains at least one of the two signals referred `to `will show danger.

Our invention consists in a combined `switch-crossing having all of the above ad-V vantages which can` be more easily and cheaply constructed and which is less liable toget ont of order than any heretofore made; `and italso consists in many details of con- Al, 2, 3, and 4.

struction hereinafter more fully described and claimed.

Referring to the drawings, Figure 1 is a plan view of mechanism illustrating our invention, showing one main track set for tion of the parts when the opposite throughtrack from the one shown in Fig. 1 is ready for use, and Fig. 4 shows the position of the parts wllen the Opposite slip-switch from the one shownin Fig. 2 is ready for use. Fig. 5 is a detailplan, and Fig. 6 is a detail sectional View, of the connections of the four end switch-points and the signals connected to the Sallie. Fig. 7 is a side elevation of the switch-stand preferably used in our invention. Fig. 8 is a sectional detail view ofthe upper portion of the stand, taken diagonally from the base of the stand on line S of Fig. 1. Fig. 9 is a detail sectional view of the lower portion of the switch-stand, taken directly through the center of the stand on the dotted line 9 of Fig. 1. Figs. 10, 11, 12, and 13 are respectively detail plan views taken on the lines 10, 11, 12, and 13 of Fig. 9, the parts above each of said dotted lines being removed. Figs. 14, 15, 16, and 17 are respectively plan views taken on line 1O of Fig. 9, showing the positions of the calns when the lever isset, respectively, at the positions shown in Figs.

For purposesV of description one .throughtrack is lettered A B, while the opposite through-'track is lettered C D. Each single letter represents the portion of the track between tlIe point where the letter is located andthe center line e f of the crossing. At some points in the specification these portions designated by letters will be referred to as ends of the crossing.

Referring to the drawings, 21 and 22 are respectively the curved stock-rails of mechanism of the class described, being connected l and C D, which cross each other, by means of the mechanism of our invention. Inside of these curved stock-rails are bent connecting-rails 23 and 24. Pivoted to the ends of these bent connecting-rails are the switchpoints 25, 26, 27, and 28. Inside of the bent connecting-rails just described are straight connecting- rails 31, 32, 33, and 34, connecting at their outer ends (beyond the figure) to an ordinary frog, which is in turn connected to the inner rails of the main tracks, which cross each other, by means of our mechanism. n the inner ends of these straight connectingrails 31, 32, 33, and 34 are movable switchpoints 35, 36, 37, and 38, pivoted, respectively, at 39, 40, 41, and 42. These movable points are tapered at their ends in the angular lines 43, 44, 45, and 46, conforming to the angle of the bent connecting-rails, so that these movable points may be moved against the bent connecting-rails, and the connecting-rail, movable point, and the straight stock-rail to which the movable point is pivoted form a continuons rail. Inside of the mechanism just described are the curved connecting- rails 47 and 48. Pivoted to the ends of these curved connecting-rails at 49, 50, 51, and 52 are switch- points 53, 54, 55, and 56. The outer edges of these switch-points are cnt away in the angular lines 57, 58, 59, and 60 in such a way that when one of these switchpoints is brought in contact with the straight connecting-rail the curved rail, the switchpoint pivoted to it, and the straight connecting-rail form a continuous track. The outer edges of the switch- points 25, 26', 27, and 28 are cut away in the angular lines 61, 62, 63, and 64, so shaped that when these switchpoints are moved on their pivots 65, 66, 67, and 68 so that one of the points is brought in contact with the curved connecting-rail to which it is adjacent the bent connecting-rail to which the switch-point is pivoted, the switch-point, and this curved connecting-rail will form a continuous track. The switchpoints 25 and 54 are connected together by tie-bars 71, which permit of their being moved together. In a similar manner switch- points 53 and 26 are connected by tie-bar 72, switchpoints 27'and 56 by tie-bar 73, and switchpoints 55 and 28 by tie-bar 74. Bolted to the switch- points 25, 53, 54, 26, 27, 55, 56, and 5s are lugs 75, 76, 77, 7s, 79, so, s1, and s2. Passing below these lugs on the ends of each set of switch-points are head- rods 83 and 84, the same being connected to the lugs just described by bolts 85 in the manner illustrated in Fig. 6, so that when these head-rods are moved back and forth longitudinally across the rails the four switch points connected to each head-rod will be moved simultaneously in the same direction. vSecured to the movable points 35, 36, 37, and 38 are other lugs 86, 87, 88, and 89similar to those just described, and illustrated in Fig. 6. Passing under the rails near the center of the crossing are movablepoint head- rods 91 and 92, rod 91 being conyable mechanism.

.Iournaled in suitable stationary standards 95, 96, 97, and 98, the formertwo adjacent to head-rod 83 and the latter two adjacent to head-rod 84, as shown, are upright signal posts or masts 99, 100, 101, and 102. Secured to these posts are signal-targets having red signals 103, 104, 105, and 106 and white signals 107, 108, 109, and 110. These signalmasts 99 to 102 are connected to the respective head-rods to which they are adjacent by slotted lever- arms 111, 112, 113, and 114. The signal post or mast 99 is so arranged that it shows white along the main track A when switch-point 25 is adjacent to the curved rail 21 and red when it is not. The signal on post 100 is so arranged that it shows white along the main track C when switch-point 26 is adjacent to curved rail 22 and red when it is not. The signal on post 101 is so arranged that the signal shows white on track D when switch-point 27 is adjacent to curved rail 21 and red when it is not. Post 102 is so arranged that the signal on it shows white ou track B when switch-point 28 is adjacent to the curved rail 22 and red when it is not. Pivoted at 117 to a tie or other fixed point is a bell-crank 118, having one arm pivotally connected to the end of head-rod 83 and having its other end pivotally connected at 120 to the connecting-rod 1217. Similarly pivoted at a fixed point 123 is another bell-crank 124, having one arm pivotally connected at 125 to the head-rod 84 and havingits other end pivotally connected at 126 to the connecting-rod 1273. Pivoted at a fixed point 128 is a bellcrank 129,having one end pivotally connected at 130 to movable-point head-rod 91 and the other end pivotally connected at 131 to a short link 132, connected at 133 to the connectingrod 121. Similarly pivoted at 135 is another bell-crank 136, having one arm pivotally connected at 137 to movable-point head-rod 84 and its other arm connected at 138 to a short link 139, connected at 140 to the connectingrod 127.

Mounted adjacent to the above-described mechanism on a suitable base 143 isa fourway switch-stand frame 144. v Journaled in the switch-stand is a shaft 146, having rigidly secured to it by a pin 147 or other suitable means a lever-arm 148. This lever-arm has an extension-handle 149, pivoted at 150 in such away that when it is desired to turn the shaft 146 the arm may be raised toa horizontal position to obtain an additional leverage,

and when the mechanism is at rest the handle may be lowered to the vertical position shown in Fig. 8 and rest in one of the four notches 151,152, 153, and 154, cut in the top 155 of the switch-stand, thereby locking the lever 148 in a fixed position until such time asthe extension-lever 149 is raised out ofthe notch. Rigidly secured to the` lower end of shaft 146 are two cams 157 and 158, placed at right angles to eachother and shaped substantially as shown. Connecting-rod 121 has a slot 159, adapted to allow the rod to tit over `shaft 146, and has bearing-faces 161 and 162,

adapted` to tit against the sides of cam 157. In a similar manner the rod 127 has a slot 163,1n it, adapted to tit over the shaft 146, and has bearing-faces 164 and 165, adapted to bear againstthe cam 158, the rod having the portion 159 passing under said cam, as shown in Fig. 9. These cams are so shaped and arranged that starting when they are in the position shown in Fig. 14 and the lever 148 is accordingly in position shown in Fig. 1 and moving the lever a quarter of a revolution to the position shown in Fig. 2' the connecting-rod 127 will be drawn inward until the parts are in the position shown in Fig. 15, the connecting-rod 121 remaining stationary during the operation. When the lever 148 is moved another quarter of a revolution to the position shown in Fig. 3, the connecting-rod 121 will be moved outward to the position shown in Fig. 16, the rod 127 remaining stationary. When the lever 148 is moved another quarter of a revolution to the position shown in Fig. 4, connecting-rod 127 will be moved outward to the position shownV in Fig. 17, the rod 121 remaining stationary, and when the lever 148 is moved on around the circle to its original position the connect'- i ing-rod 121 will be again moved inward to the position shown in Fig. 14, rod 127 remaining stationary. In other words, the cams are so shaped that during each quarter of the motion of the-lever in one quadrant of its swing one of the connecting-rods is movingin one direction, the same rod being moved inthe opposite direction when the lever isin the opposite quadrant of its circle of motion, and when one rod is moving in either direction the opposite connecting-rod remains stationary.

` In the operation of our invention we rst set all of the parts in the positionshown in Fig. 1, in which the lever-handle is in the position shown, the cams being in the position of Fig. 14. In this position the rails are set for main track A B and the masts 99 and 102 are turned so thatthe white signals 107 and 110 appear on said track, while the masts 100 `and 101 are so set that the red signals 104 and 105 appear upon the opposite track C D. In this position the two white signals 107 and 110, considered together, indicate to the engineer approaching from either direction on `thetrack A B, which these signals control,

through the crossing on the main track. The signal nearest to him also conveys to him the information that the switch nearest to him is not set for slip-switching. On the other hand, the presence of the red signals 104 and 105 indicate to the engineer approaching on the opposite track C D from either direction that the track is not set for through traffic, and the signal nearest to him indicates to him that the switch at that point is set for slipswitching; but it does not give him permission to proceed onto the slip-switch. We now raise the handle 149 and turn the lever, 148 a quarter of a revolution to the position shown in Fig. 2 and let the handle drop down into its notch in the stand, thereby locking the parts in position. In making this quarter of a revolution we move the cams of the stand to the position shown in Fig. 15, thereby drawing in the connecting-rod 127, which has moved the movable-point head-rod 92, and consequently moved the movable point 37 on track B away from the bent connecting-rail 23 and the movable point 38 on track D into contact with the bent connectingrail 24. This motion of the lever-handle 148 has also simultaneously moved the head-rod 84 to the left, thereby moving switch-point 27 against curved stock-rail 21, switch-point 55 against 'straight connecting-rail 33, switch-point 56 away from straight connecting-rail 34, and switch-point 28 away from curved stock-rail 22. During this motion the points in tracks A and C remain stationary. In this position the mechanism is set, as shown, for slipswitching from track B to track O, or vice versa. This motion of the lever has also turned the signals on masts 101 and 102 a quarter of a revolution, so that the red signal 106 now shows on the track B and the white signal 109 shows on track D. The signals ICO now show an engineer approaching the crossy ing from either direction on either main track one red andone white signal set against him `on his own main track. An engineer approaching on tracks B or C will find the red signal on hisown track nearest to him as he approaches and the corresponding red signal on the slip-switch to which he desiresto go, these two red signals indicating to him that he can pass around from track B to C, but cannot pass from C to D or A to B--in'other words, that the main-line crossing is closed. We now raise the handle 149 and move the lever 148 another quarter of a revolution to the position shown in Fig. 3 and again let the lever 149 drop, locking the parts in position. This motion has moved the rod 121 upward to the position shown in Figs. 2 and 16, which IIO IThe tracks are'so set that both signals on these tracks show white, while the signals on tracks A and B show red. In the above movement the parts y moving rod 127 outward and the movable points and switch-points on tracks B and D to the position shown in Fig. 4, the movable points being moved to the left, the four switch-points being moved to the right, the signals on track B being moved to white and on track D to red. During this motion the parts on tracks A and C are stationary. In this position it will be seen that slip-switching is afforded from track D to track A, or vice versa, and that the two signals on said track D indicate red, while the two signals on tracks C and B indicate white. `We now move the lever another quarter of a revolution and return the parts to their first position. The lever may now be moved around again in the same or reverse direction, as desired, in the latter case reversing the order of successive positions of the parts.

We desire to call particular attention to the fact that we are the rst to move the switchpoints andthe movable points in one end of the crossing simultaneously by one lever mo# tion, while the switch-points and the movable pointsin the otherend of the crossing remain absolutely at rest, and that by this feature We obtain the two results of, first, being able to have each of the four separate positions of the controlling-lever set the mechanism for a ldirect crossing on one track, a slip-switch from one track to the other, a track-crossing ways being open at a time.

on the opposite through-crossing and for the opposite slip-switch, only one of said passage- We are also by this construction able to so operate the signals that, as described, the signal nearest the engineer as he approaches the crossing always indicates to him Whether or not the switch nearest to him is set for the main line or for slip-switching and also that the two signals on opposite portions of the same main track indicate, when taken together, whether or not the main track is clear for a crossing.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
