swrrcI-r MECHANISM Ann 'mAm-cARRiED ACTUA TING MEANS THEREFOR.
To all whom it may concern: s
Be it known that I, EDWARD HAAs,fa citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and.
useful Improvements in Switch Mechanism and Train-Carried Actuating Means There- 7 for; and I do declarethe following to be a ful1, clear,- and exact description of the inventlon, suchas willenable others'skilled in the art to which it appertains to make and use the same. s 1
This 1nvent1on has IGlfltlOIl to s new and useful nnprovementsln switch mechanism and train-carried actuating means therefor,
and has for its object to provide asimple and positively operating form of mechanism adapted to be arranged longitudinally of a:
railway or other track and operate to throw the switch when actuated andmeans adapted to be ,carriedby the en'gine of a train, for actuating the switch mechanism.
While, the invention is particularly applicable to steam railways,it maybe used in connection with street railway service.
View, the invention consists of certain novel features of construct on, comb natlon and arrangement of parts, as will bemore fully pointed out in 7 I of the cross ties, so that it may be swung or moved either to theright or to the left reladescribed and particularly the appended claims. v l s In the accompanyin drawings,fFi-gure 1 is a side elevation 0 a section of a railway track with the switch mechanism applied thereto and an engine provided iwith my improved switch actuating means running thereon, the shoe of one ofthe vertically movable operating rods of the switch actuating mechanism lowered to engage the cam plate or block of one of the switch throwing bars of the switch mechanism to throw the switch; Fig.2 isaplan-view of a section of a railway track with theswitclr mechanism in position; Fig. 3 is an enlarged detail cross sectional view takenthroughithe locking bar or member and the ends of the switch tongues; Fig. 4: is a vertical sectional view of the switch tongues. and under one end of a laterallymovable bar for connectA ing the ends of the tongue; Fig, 5 is a cross sectional View taken on the plane indicated 7 by the dotted lines 55 of Fig. 3. 7

of a section of a railway track. The switch tongues are'pivotally connected at their 1nnerends tojone of the cross ties, as usual,in anysuitable manner, and are connected at their free or outer ends to a laterally movable connecting bar 4 arranged to work under the track rails and in a corresponding guide groove in one of the cross ties. One set of switchthrowing bars 5 is arranged longitudinally of and at each side of the track, the bars comprising each set being connected'at their inner ends to and near the ends of said laterally movable connecting bar 4, and pivotally connected intermediately of their ends to the tops of the ad- ;jacent cross ties,-and the'outer ends of the bars of oneset-being connected with said ends of the bars of the other set by transversely disposed connecting bars 6, mounted to'slide under" the track rails on the adjacent cross tiesv A locking bar 7 is arranged between and hingedly connected at its ends to the outer'or free ends of the switch tongues 3 for locking the switch in position after it I g s has been thrown. This bar is made in two .With the foregoing and other objects in,
sections 8 and 9, section 8 having a longitudina'l central recess, 10 in its inner end through whlch extends the central or 1ntermediate portion 11 of a U-shaped link or hinge member 12, hinged-at its ends to one tively to the track rails. The other section is provided at its inner end with a tongue '13, corresponding, with and adapted to be outer endthereofto within a suitable distance of its inner end, for receiving the central or intermediate portion of the U shaped link or hinge member 12.. These members are detachably connected by passing a vertical pin 15 through corresponding alined openings or apertures in the, ends of said tongue at a point inwardly of the central or intermediate portion of the U-shapedlink.
practice, and assuming that the switch is" thrown to the right relatively to the direction of the engine, (see Fig. 1), the lockingbar will also be caused to move to the right and swing or move the U-shaped link .or hinge member 12 toward the right hand track rail. locking bar is in this position, the right hand It will be obviousthat when the switch tongue will be held in secure engagement with the adjacent track rail, the sections of the locking bar being made of heavy metal to cause this engagement to be more effectual.
The purpose of making the central recess 14 of the tongue 13 of one of the sections elongated in form is to allow for the necessary expansion of the locking bar when being moved from one side of the track towards the other, as during this operation the central portion of the bar will be necessarilyraised with the U-shaped link or hinge member 12 and the length of the locking bar thereby slightly increased. Cam blocks 16, having their inner faces at their outer ends curved or beveled outwardly, are secured on the upper faces and at the outer ends of the switch throwing bars 5.
The mechanism carried by the engine 17 for actuating the switch mechanism comprises bell crank levers 18, one arranged near the center and on each side of the engine, and vertically movable operating rods 19 connected to the ends of the forwardly extending arms of said levers, said operating rods having shoes 20 for-med on or secured to their lower ends for engaging the inner beveled surfaces of the cam blocks to actuate the switch mechanism. Longitudinally disposed connecting bars or rods 21 are connected at their front ends to the vertical arms of the bell crank levers and at their rear or opposite ends to operating levers 22 pivotally connected to the sides of the engine in position to be grasped by the engineer or fireman.
In practice, assuming that it is desired to throw the switch to the left relatively to the direction of the train, the engineer pushes forwardly on the upper or front end of the operating lever 22 at the right hand side of the engine, causing the adjacent movable operating rod 19 to simultaneously move downward so that the shoe 20 at the lower end thereof may be in position to engage the beveled surface of the adjacent cam block 16, and through the medium of the switch throwing bars 5, throw the switch to the left. Blocks 28, having inclined upper faces or surfaces are arranged near the track rails longitudinally of the track for automatically throwing either of the vertically movable operating rods into its normal position after the switch has been thrown.
To eliminate friction as much as possible to enable the switch mechanism to be operated easily, suitable wheels or rollers 24- may be journaled under the laterally movable connecting bar at for connecting the switch tongues and the transversely disposed connecting bar 6 connectedto the outer ends of the switch throwing bars 5 to run on the tops or upper faces of the cross ties under said connecting bars. A switch stand 25 is arranged at one end of the laterally movable connecting bar on the switch tongues, for enabling the switch mechanism to be actuated manually or by hand, instead of from the train, should it be desirable. This stand essentially comprises a hollow base 26, fixed near one end of said laterally movable connecting bar 1, and a vertically disposed switch stand rod 27, which works through said base. A mutilated gear 28 is arranged at the lower end of the rod 26 to engage corresponding teeth 29 formed on one edge and at one end of the laterally movable connecting bar. A turning lever or handle 30 is pivotally connected to the switch stand rod to enable it to be turned in actuating the switch mechanism to throw the switch, and a catch 31 is arranged on the switch stand rod to engage the free end of the turning lever or handle when not in use.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
