AUTOMATIC RAI LROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 492,790, dated March 7, 1893.

Application filed April 29, 1892.

To all whom, it' may concern;

Be it known that we, GEORGE N. EINsELE, and GEORGE W. DE GRASSE, citizens of the United States of America, residing at Crete, in the countyof VVilland State of Illinois, haveinvented certain new and useful Improvements in Automatic Railroad-Switches, of which the following is a specification, reference being had therein to the accompanying drawingsand the letters andignres of reference thereon, forming a part of this specification, in which- Figure lis a plan view ofa section of a main rail road track and switch track, and of the switch operating devices arranged along the side of the tracks, sections of the rails being removed so as to contract the length of the tracks and bring theswitch operating devices nearer each other to show their operation more clearly. Fig. 2 is a plan view of a section of the main track of a rail road,'and of the switch track, and of the base of the switch stand and its operating parts, the top of the switch stand, and its operating lever being removed to more clearly show the parts below them, which are in the reverse position from that shown in Fig. l and as they would appear when theswitch is closed. Fig. 3. is a plan view of a pair ofv toggle bars and their slide and bell crank mechanism connected with the switch stand mechanism by means of cables or rods for moving the switch rails by means of the said toggle bars being engaged by a passing train. Fig. 11 is a side view of a weight mechanism for holding taut cables or rods connecting the mechanism shown in. Fig. 3 with a bell crank and toggle arm mechanism shown at the bottom of Fig. 1, andFig. 5 is a top plan 'View of theswitch stand its mechanism connecting it with the switch rails being omitted.

This invention relatesV to certain improvements in automatic rail road switches, of the class wherein an approaching locomotive or car moves the switch rails by means ofengaging mechanism connected with the switch stand, and located at considerable distance therefrom which improvements are fully set forth and explained in the following speciication and claims.

Referring to the drawings A is an ordinary rail road track and S is an ordinary point sein No. 431,100. or@ man rail switch connected by means of the switch bar B, and connecting rod r, with the switch stand mechanism.

The switch stand mechanism is shown at the upper end of Fig.'l, as it would appear when the switch is open and is shown in Fig. 2 as it would appear when the switch is closed, and is constructed as follows:

D represents aziioor or platform on which rests and is securely fastened the base plate J of the stand.

9 is the' switch stand -shaft having its lower end stepped in said base plate its upper end being journaled in the frame T of the stand shown in Fig. 5 and is provided on its upper end with thejointed arm V adapted tofall in the notch X and held and locked thereinby means of the hasp Y for locking the switch.

1. is asegmental plate that lies on base plate J and is boxed on the lower end of shaft 9, loosely so it can oscillate to the limit permitted by the pins 12 and 13 secured in its upper face as they alternately are engaged by bell crank 7 secured on shaft 9 immediately above plate 1.

6 is a sliding bolt connected with the inner arm ofthe bell crank 7 by means of thelink 14, by means of which connection said bolt is moved forward to pass through the catch secured to plate J as shown iny Fig. 1 when the switch is open to secure it open.

3 and 4 are a pair of levers pivotally connectedito plate 1. The .outer end of lever 3 passes under connecting rod r ina notch in its under side. Lever 4 has itsouter end connected with bolt 6,.and itsinner end engages the inner end of 'lever 3, so that when the switch stand mechanism is inthe position shown in Fig. 1 said levers move the connecting rod r and the switch rails forward.'` Saidrod ris Y provided with a slot at its inner end asy through `which a' wrist bolt eonneets-itwith oscillatingA plate l and said rod has movement on said plate within the limits of said slot, and has behind it a spring 2 for spring pressing it forward. The object of ,giving said connecting rod such movement within the limits of said slot is to permit the switch to be locked by means of bolt 6 in case some obstruction should prevent the switch rails from moving the full distance required, the

lsaid spring and levers however serving to eX- hown ert a constant pressure to move the switch considerable distance from the switch stand v along side the track and is designed to support a pair of toggle bars adapted to be engaged and'moved laterally by a passing car and also to support the mechanism connecting said toggle bars with the switch stand mechanism. The mechanism referred to and used in connection with said toggle bars consists of the slide 18 attached to bed plate F, by means of stud bolts vpassing through its two slots 2O and is connected with toggle bars 15 by means of the link 17, and by means of which link and toggle arms said slide is reciprocated within the limits of said slots. Said toggle bars are spring pressed forward toward the track by means of the spring 35 connected thereto by means of the arm 34. Said slide 18 is provided on one side with a hook 50 for being engaged by va hook 22 to secure said slide in its rearward position, and is provided on its opposite side in advance of hook 50 with a hook 51 for engaging with a similar hook 49 on the side of the parallel slide 25 for moving slide 25 rearward within the limits of its slots 26 and 27. Said slide 18 is also provided at its rear end with the vside hook 19 for engagement with the spring bolt 24 for the purpose of securing said slide in the position shown in Fig. 1 when the switch is closed. Said switch is always opened by means of an'operator turning the shaft 9, with bell crank 7 of the switch stand by means of arm V shown in Fig. 5, and as said spring bolt 24 is connected with said bell crank 7 by means of the cable 62, said bolt at such time is withdrawn from contact with hook 19 of slide 18 and so remains until a passing train engages the toggle bars as set forth and operates the switch stand mechanism to close the switch, return bell crank 7, and slacken cable 62 and permit said sliding bolt 24 to move forward to be engaged by hook 1.9 of slide 18 as said slide moves backward to the position shown in Fig. 1 for the purpose of securing said slide in case hook 22 should by accident become disengaged from said slide and permit the toggle bars connected to slide 18 to move out at the wrong time. Said sliding bolt 24 will so remain in contact with slide 18 until the switch rails are again opened as before stated, when said bolt 24 will again be withdrawn from contact with slide 18 so it will be free to be operated by a passing train as set forth.

The form of slot 26 in slide 25 permits its hook 49 to be engaged with hook 51 of slide 18 when said slide moves forward to the position shown in Fig. 3. Said slide 25 is spring pressed forward by means of the spring 30, and is connected to the bell crank 31, which is pivotallyv connected to bed plate F. g Said bell crank is connected with bell crank 7 of the switch stand through the medium of the cable 61 and links 10 and 33 so that when slide 25 moves rearward, it will through the medium of said bell crank and cable operate the switch mechanism. A lever 29 is pivotally attached at about its center to the bed plate F and has one end pivotally connected to the outer end of said spring bolt 24, while its opposite end is connected to the oscillating plate 1 of the switch stand through the medium of the cable 60 and links 11 and 32, which is for the purpose of taking up the slack in cables 61 and 62.

23 is a lever pivotally connected at about its center to the bed plate F, and is connected at one end with the hook 22, which engages with hook 50 of slide 18. Said lever 23 is connected by means of the cables 63 and 64 with the double bell crank 45 pivotally attached to a bed plate N, located at a considerable distance from bed plate F along the track. Said double bell crank 45 is pivotally attached to a slide 42 connected by means of a link 41 with a pair of toggle arrns40 for reciprocating said slide 42 Within thelimits of its slots 43, through which stud bolts 46 pass to attach said slide to said bed plate. Said cables 63 and 64 are to be crossed between said double bell crank and lever 23, and betweenrtheir ends said cables are weighted to keep them taut and insure prompt action. These cables are shown as passing under rollers C over sheaves P and under sheave n from the frame L of which is suspended the Weight W through the` medium of the pawls O which engage racks in the posts R, at each side of said weight Lto prevent the weight from being bounded upward when the cables are suddenly operated upon by a passing train. These pawls are angularin form and pivoted at their angles to'studs on the upper side of said weight, and are pivotally connected as shown to the frame L of sheave n so that the weight W will hold them engaged with their ratchets Z as shown. In the drawings one weight serves to weight the two cables, but if for any reason it is desirable, a separate weight may be used to keep taut each separate cable.

The toggle bars 15 and 40 are respectively pivoted at their outer ends to suitable foundations so that when engaged by a passing car they will not be moved out of place and are intended to be arranged at the side of the main track and near enough to it so that they may be engaged by suitable mechanism on a locomotive or car. In Fig. 1 a portion of a locomotive is shown having a sliding bar arranged on the side of the cow catcher frame adapted to be reciprocated up or down by IOO IIO

means of rod and leverage mechanism extending into the cab and not necessary to be shown.

In operation when the train is approaching the switch from the direction shown in Fig. 1 if the switch should be open which will be indicated by an ordinary semaphore m on the switch stand, the sliding bar or other mechanism on the engine is intended to be set in the proper position to engage the side of toggle arms 40 next the track and move their jointed ends laterally from the track for the purpose of operating the slide 42 and the double bell crank 45 pivoted thereto and release hook 22 from slide 18 so as to permit it to move forward to the position shown in Fig. 3 and so its hook 51 will engage hook 49 Of slide 25 which is permitted by the form of slot 26 in said slide. The spring 7l bearing against the back of slide 25 permitting a yielding lat- `eral movement of said slide so said hooks may engage each other as shown in Fig. 3. As before stated the bolt 24 is free from slide 18 at the time the switch is Open so as to permit such forward movement of slide 18. When the engine moves nearer to the switch it in a similar manner engages the toggle bars 15 slidelS and also slide 25 which are moved rearward until the form of slot 27 of slide 25 causes the two engaging hooks 49 and 5l to be disengaged, when the spring 30 will return slide 25 to its first position and slide 18 will also have been returned to its iirst position and held by hook 22 and bolt 24 as shown in Fig. 1 as at such time said bolt can engage said slide hook 19 as the switch has been closed by means of its connection with the bell crank 31 attached to slide 25 through the medium of cable 61 connecting said bell crank with bell crank 7 of the switch mechanism so that in case the switch should be open a train approaching on the main track will automaticallyclose the switch so that the train may pass in safety on the main track. This device may be duplicated so that one may be arranged at each side of the switch to operate it from either direction if desired.

The working parts described are all intended to be covered to protect them from the weather and insure their proper action.

The toggle bars are intended to be quite long so that their lateral movement will not be sudden to break the devices to which they attach. v

The shaft 9Of the switch stand is provided with a pinion near its upper end which meshes with a pinion on the shaft of the semaphorem for turning the semaphore when the switch stand is Operated which pinions are shown in broken lines in Fig. 5. In case the engine was coming from the Opposite direction on the main track when the switch is open as shown in Fig. 1 the'langes Of the wheels will move the switch to the position shown in Fig. 2. In such casethe slot in 65 the rod r will permit it to move backward to the end of `said slot before it moves plate 1. and by such movement drawsbolt 6 by means of the levers 3 and 4and after said bolt is drawn 'arm 70 on roda"l will engage bell crank as shown in Fig. 2 and move it to the position shown in said figure and hold it in such position till the switch is set back to the position shown in Fig. 1. y
