MECHANISM FOR OPERATING RAILWAY-SWITCHES.

SPEGIFIPATIQN forming part Of Letters Patent N 0.74.1,644, dated October 20, 1903.

Application filed October 28,1901- Serial No. 80.210. (No model.)

To all whom it may concern: I

Be it known that I, GEORGE W. FERNSIDE, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Mechanism for Operating Railway-Switches, of, which the fol lowingis a specification, I

My invention'relates to mechanism for operatlng railway-switches, and has for its object the provision of improved'devices under the control of the motorr'nan for accurately.

and expeditiously accomplishing this result, and that, too, whether the car is going in one direction or in the'other direction.

In the accompanying drawings, in which like numeralsdesignate similar parts through out the several views, Figure 1 is a side elevation of a street-railway car with the sills and one of the trucks partly in section, showing my invention applied thereto. Fig: 2-is a plan view showing the invention appliedt'olaterally actuating the switch-shifting de--' vices.

Referring to the drawings the numeral 5 indicates a railway-track, 6 a branch track or siding, and 7 a pivoted switch, all of common construction.

Designated by the numeral 8-is a car, shown as of the double-truck electric street-railway kind, a portion only of said car being illus--' trated, and by the numeral 9 is the truck of said car, these parts being of the usual con struction. Beneath the-body of the car my.

improved switch-shifting mechanism is prof erablylocated, and this mechanism consists of rock-shafts 10 10, one set located at one end and the other set (not shown) at the opposite end of said car. To the rockshaft 10 is rigidly secured an arm 12, and splined upon the rock-shaft 10, so that it may have a limited sliding movement thereon, is a prefer- :side. greciprocation a plunger, (designated by 22,) said plunger having an" angular (portion 23, conforming to the shape of the opening 21 14, as illustrated in Figs. 1 and- 2, and each of these springs bears at its forward end I against the head of a stem 15, said stem being bifurcated or otherwise constructed at its lower end to receive a roller 16, having a conical or beveled periphery-for accomplishing a purpose hereinafter set forth. For normally raising the arms 13 13, carrying the switchshifting rollers, weighted arms may be employed, as illustrated in Fig. 1, or other devices may be substituted for the weights for accomplishing this purpose, if desired. To the arm 12 is articulated a connecting-rod or pit- 'man. 17, which passes through guides 18, se-

cured either to the truck 9 or to the under side of the floor of the car 8, as shown in Fig. 1. This connecting-rod 17 is articulated at 17 to a c'rank-arm-19, rigidly secured-to a rock- .shaft20, and also fixedly secured to this rock shaft 20 is adepending tubular. sheath 21, slotted on one side at 21 and having an opening 21 of rectangular formation in its lower In this sheath is mountedfor vertical a shank 23, a head .23 and a preferably inclined tip or nose 23 Surrounding the shank 23 of the plunger is a spring 24, which bears at its upper end against the head 23 andat its lower end upon the bottomwall of the tubular sheath, and this spring normally tends to elevate the plunger within the sheath, so that the tip or nose 23 0f said plunger will be held above the track, as illustrated in Fig.

1'. Also journaledin bearings dependingfrom the framework of the car is a second. rockshaft 50, having an arm 24 and'a depending sheath-25,similarj to the sheath 21 illustrated in Fig. 3, and containing, as does said sheath 21, a spring-actuated plunger and connected to this arm is a rod 26, articulated at its fortively, and a laterally-projecting arm 29 29, respectively. These arms 29 29 enter the slots 21 of the sheaths or depending tubular bodies secured to the rock-shafts 20 and 50, and, as will be obvious, when either rockshaft is actuated by means hereinafter described the arm 29 or 29', projecting therefrom, will be caused to bear against the head of the plunger in the sheath and force said plunger downward against the stress of its elevating-spring 24. Connected to the arm 28 of rock-shaft 27 is a rod or pitman 30, which extends along the top of the truck in line with the longitudinal axis of the carbody, as illustrated in Figs. 1 and 2, and is attached at its forward end to anarm 31, depending from a rock-shaft 32, journaled in hearings on the under side of the car-platform. This rock-shaft 32 also carries anotherarm 33, to which is articulated or against which bears a plunger 3e, normally elevated by a spring 35 and adapted to be depressed against the action of said spring by the foot of the motorman. Arranged parallel to the rod or pitman 30 is a second rod or pitman 35, articulated at one end to the arm 23 of rock-shaft 27' and at its opposite end to an arm similar to the arm 31, above described, the devices just set forth being operated by a foot-actuated treadle or plunger 36 in the same manner as are the connecting-rod 30, the rock-shaft 27, and the arm 29.

As is well known, on street and other railways the side tracks or turn-outs are located sometimes on one side of the main track and again on the other side thereof, and it is a desideratum when the car is proceeding along the maintrack to be able to shift the switch in either direction desired when requiredin other words, to open or close said switch as circumstance may demand-and in order to accomplish these results the switchshifting devices must be capable of a considerable range of movement, so that at the exact time necessary the switch may either be closed or thrown open. To carry out this work, I arrange at the necessary points in the track stops or projections 37, one of which is shown in Fig. 4, audit will be understood that others will be disposed along the length of the line wherever needed. To permit the switch-shifting rollers 16 16 to actuate the switches in order that the movement of the car may be positively controlled, these devices and the mechanism for actuating them are provided in duplicate sets, one set being located at one and the other at the opposite end of the car. While but one set is shown, it will be understood that the opposite end of the car will be equipped with like devices. In carrying out these results the switch-shifting rollers 16 16 must be so arranged that they can be moved laterally a limited extent upon their supporting-shafts and so held and controlled that their beveled peripheries may bear against either side of the switch to open or close the same, and with this object in View I mount the hollow arms 13 13 upon the shafts 10 10 in such a way that while conforming to the rocking motions of their shafts they may be slid thereupon laterally to carry them to the desired side of the switch. For accomplishing this result each shaft 10 and 10 in the construction illustrated is provided with a spline 10, and the arms are grooved to re ceive said splines. For shifting the rollercarrying arms I preferably employ levers 38 38, pivoted at 39 to the car-platform and each connected at its lower end to the arm in any desired manner, as shown in Fig. 5. Each of these levers is provided with a suitable handgrasp, and, as is obvious, by rocking the lever the arm may be slid along the shaft to bring the roller to the desired position. Each lever may work over a usual quandrant45, (see Fig. 5,) to which it may be secured in any desired way to lock the lever and arm in its shifted position.

To prevent undue jar or concussion, the springs 14 let are employed, and they permit a slight yielding movement of the roller when it comes into contact with the switch and avoid breakage of the parts.

In operation my improved switch-shifting mechanism works as follows: Should a car be approaching a side track or turn-out when going in either direction, the motorman by placing his foot upon one of the plungers 34; or 36 will actuate the connecting- rod 30 or 35, as the case may be, and through the shaft 27 or 27 and its arm 29 or 29 will depress the plunger 22, for example, against the action of its spring, bringing the nose orpoint of said plunger to such position that as the car advances said nose or point will come into contact with one of the stops 37, the result being that the sheath 21 is swung upon its axis and the rod 1 7 is shifted to throw down one of the arms 13, so that the conical or beveled roller 16 on the end of said arm will wedge itself between the pivoted switch and the side rail of the track and will throw the switch, if desired, to the open position. Should a switch be open, one of the levers 38 38 is grasped by the motorman, who turns said lever upon its pivot 39 and slides the arm carrying the roller to the position necessary to throw said roller against the inner side of the switch for the purpose of closing the same; but a very limited movement is required for accomplishing this result, and, as illustrated in Fig. 5, the arms are splined to their shafts or otherwise so connected thereto that they may move along the same.

From the above description it will be seen that by providing the car with duplicate sets of switch operating mechanisms the pivoted tongues or switches may be absolutely controlled by the motorman and that, too,whether the car be proceeding in one direction or in another direction or whether it be desired to open or to close the switch. W'hen the nose or point 23 comes into contact with the stop 37 of the track, a slight jar will be felt which will indicate to the motorman that the switchshifting roller is in proper position to accomplish its work.

Many changes may be made in the constructional details of my invention, and it is not limited to the precise devices illustrated and described. In some instances on singletrack lines a single switch-shit ting roller and its actuating mechanism and a single means for throwing down the plunger 22 in its sheath may be employed, and the invention is not limited to the plurality of devices illustrated and described.
