LEON J. MONGEL, F JOHNSTOVN, PENNSYLVANIA.

RAILWAY-SWITCH.

Application led March 29, 1917.

T 0 all whom it may concern Be it known that I, LEON J. MONGEL, a citizen of the United States, residing ai, Johnstown, in the county of Cambria and State ofy Pennsylvania, have invented certain new and useful improvements in Railway-Switches; and I do hereby declare the Y following to be a full, clear, and exact de'- scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railway switches, and the principal object of the invention resides in the provision of'a means for operating a switch from a car without requiring that one of the crew leave his place on the car.

Another object of the invention is to provide a trip carried by the car for operating the switch lever. y v

Still another object of the invention is to provide an extensible pull bar so that after the switch has moved to closed posi` tion the switch lever may be moved without straining any of the parts.

l/Vith these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a top plan view of a track showing this switch applied thereto;

Fig. 2 is a longitudinal sectional view through Fig. 1, showing the car moving toward the switch;

Fig. 3 is a View showing the switch operated and illustrating the operating lever en# gaging the pan which extends beneaththe c'ar;

Fig. 4 is an enlarged detail view of the extensible bar, bell crank and link mechanism by which the switch point is moved:

Fig. v5 is a longitudinal detail sectional view of the extensible bar;

Fig. 6 is an enlarged transverse sectional view of the bar;

Fig. 7 is an enlarged transverse sectional view on line 7 7 of Fig. 1;

Fig. 8 is an enlarged detail sectional view through Fig. 1, illustrating the method of pivoting the locking lever; and

Fig. 9 is a top plan view of the trip mechanism mounted on the car.

Referring to the drawings, the numeral 1 designates as an entirety', a railway track of the ordinary construction, consisting of the rails 2, one of which isv curved outwardly Specification of Letters Patent.

as at Sto provide the switch while the opposite rail extends in the same plane as clearly illustrated in Fig. 1. Coperating with the rail'i is the switch rail 4t and pivotally connected as at. 5 to the end of the rail 2 adja-V cent the rail 3 is the switch point desig nated by the numeral 6. This switch point is adapted to be moved into a recessi'yformed in the curved portions 8 of the rail 2, when the switch is operated. Y

A link 8 is pivoted to theswitch point and the' opposite terminal of said link is pivoted to the arm 9 of a bell crank designated generically by the numeral 10, which in turn is pivoted at 11 to the cover plate 12 of the track mechanism. The opposite en d of the bell crank is pivoted to the extensible bar. Extending laterally from the link 8 is an ear 1st provided with a stud 15 which is surrounded by one end of a compression coil spring 16. The opposite end o'f said compression coil spring surrounds the stud 17 formed on the ear 18 which is attached to any suitable support and the spring, 16

normally holds the switch point out of the recess 7 The extensible link 13 hereinbefore referred to' consists of a pair of bars 19 and 20 which are arranged to slide against each other and the bar 19 has secured thereto 'aA head 21 at one end while the end of the bar 2O is provided with the head 22, A compression coil spring 23 surrounds the bars 19 and 20 and abuts the headsl 21 and v22, so as to yieldably hold the link at its shortest length. The end of the bar 19 opposite that having the head 21 formed thereon is provided with a stirrupr shaped yoke 2e having extending upwardly from the end wall thereof, a lip or extension 25. This ycke is adapted to receive the lower' end ofr the operating lever when the same is thrown intol operative position and is s'lidab'le between the parts in which the operating lever is pivotally mounted.

The switch operating lever herein'before referred to is designated by the numeral 26 and is provided near one end with outwardly extending trunnion's 27 which are journaled in the brackets 2S supported by the cover plate 12 in such a manner that when the lever is swung on its pivot, the short lower end thereof will engage the wall 25 of the stirrup shaped yoke 24, so as to exert pull on the extensible link 13. The lever operates through a slot 29 formed in the cover plate 12, and formed in said cover plate or pan 33, the forward and rear ends of which are upturned as at 3e to form shields against which the lever 26 engages. Secured to the forward end of thecar is a bracket 35 having rotatably mounted in its forward end a shaft 36 one end of which has secured thereto a pinion 37 which is arranged to operate against the face of the bracket 35. A suitable sleeve 38 is mounted on the opposite end of the bracket and serves as a spacer to hold the pick up arm 39 spaced from the bracket 35 as is clearly illustrated in Fig. 9. The pick up arm 39 tapers toward its lower end which is Vsharpened so as to enter the recess in the plate 12fand engagebeneath the Yfinger 31, so as to cause the end of the lever to Vbe swung upwardly until the linger rides over the hub portion of the pick up arm 39 at which time .the pan 33 will have moved so as to obstruct Vthe downward. movement of the lever 26 and thusI hold the switch in operated position until the car has passed entirely over the same. In order Vto control Vthe movement of the pick up arm 39 a bracket /10 is attached to the car and pivotally supports a lever 41 the forward end of which has formed integrally therewith an arcuate rack bar 42 which meshes with the pinion 37 so that upon rocking the lever vthe pinion will be rotated. In order to normally hold the arm upwardly a retractor coil spring 43 is attached to the car bottom and to the rear end of the lever 41 and pivotally connected to the rear end of said lever is a plunger rod 4A having a pedal Ll5 provided at its upper end so that the operator of the car may step on the pedal, thus pushing the plunger rod downwardly and causing the lever 41 to rock on its pivot thereby throwing the free end of the arm 39 downwardly into contact with the plate 12.

Ity will be apparent from the foregoing that in use, when it is desired to throw the switch, the operator steps on the pedal 45 thereby causing the arm 39 to swing downwardly so that its free end engages the plate 12 and enters the recess 30 formed therein, thus engaging the under side of the linger 31 and picking up the free end of the lever 26. The finger 31 rides over the upper Copies of this patent may be obtained for shaped yoke 24 which in turn will cause pull to be exerted on the link 13 thus operating the bell crank 10 to move the switch point 6 into the recess 7 against thecompression of the spring 16. In order to avoid straining or breaking the parts, the link 13 is made extensible, so that after the switch point has been moved into proper position, further movement of the lever may be `had without danger'of injury Vto the various parts. After the car has passedover the switch it will be seen Vthat the spring 16 will return the switch te open position and the lever will be thrown into the slot 29 with the finger 31 in `the recess 30 by the force oi" the returning of the switch and the weight of the long end of the lever. Y yWhen a car passes without operating the same, it will be understood that the arm 39 is left in raised position, thereby avoiding any movement of the lever 26.

l/Vhile in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arranvement of parts as will fall within the spirit and scope of the appended claims.

IN hat is claimed is 1. The combination with a railway track, of a switch having a movable switch point, a. link pivotally connected to said switch point, a bell crank having oneof its arms -pivoted to the link, an extensible link pivoted to the opposite arm of the bell crank, al yoke on the last mentioned link, a lever pivoted between the rails of the track, a lifting finger on the end of the lever, said lever when raised to vertical position engaging the yoke to exert pull on the link and move the switch point, and ear carriedl means to engage the finger toY lift the lever.

2. In a switch, a movable switch point, said switch point being normally held away from its rail, a link connected to said switch point, a lever pivoted to a railroadv track between the rails, an extensible link connecting the lever with the first mentioned link and adapted to exert pull thereon to move' Y Y WashingtomD.
