SPECIFICATION forming part of Letters Patent No. 398,169, dated February 19, 1889. Application tiled November l, 1888. Serial No. 289,743, (No model.)

To all whom b may concern.'

.lle it known that l, JAMES lVILLIAM LEs- LIE, of Everett, county of Middlesex, State ot Massachusetts, have invented an Improvement in Automat-ic Railway-Switches, oi' which the following description, in connection with the accompanying drawings, is a spccitication,like letters on thedrawings rep- A rcsenting like paris.

This invention has i'or its object to construct a switch for railway-tracks which is operable by means ot' a device located upon a ear, the invention being especially appliea ble for street-railways, and the operating device located upon or carried by the car being operated by the driver.

In accordance with this invention the switch or tongue is secured to a stud which is partially rotated or turned in one or the other direction by rods or bars which are moved longitudinally by bell-crank levers turned on their pivots bythe simultaneous action oi the wheel of the car and of the device controlled by the driver.

The invention consists in details of construction to be hereinafter pointed out.

Figure l shows in plan view a small sec- Ational track having a switch constructed in accordance with this invention; Fig. 2, a longitudinal section of the track, taken on the dotted line, Fig. l, and also a sectional view of a portion of a car provided with a device operable by the driver; Figs. 3 and 4, details to be referred to, and Fig. 5 a modiiicaftion to be referred to.

The rails o, and the switch or tongue 1) are all as usual. The switch or tongue is fastened to a stud, b', which passes vertically through the material of the rail and into the bed or foundation, it being understood that the foundation is recessed to receive the opn erating parts. A plate or bar, e, is secured to the stud b within the recess or chamber in the bed or foundation, said plate or bar having loosely connected with it rods or bars d d', extending horizontally in opposite directions. 'lhe rod or bar d is looselyconneeted at its opposite end with one arm, as 2, of a bell-crank lever pivoted at 3, the other arm, 4, of the said lever being recessed near its outer end. A cross-bar, 5, passes through 'the recess formed in the arm 4 of the bellthe studs, as 7, occupying a position to be l acted upon by the tread-tace of the car-wheel,

and the other stud, as S, occupying aposition remote therefrom, so as not to be acted upon bythe car-wheel.

A hell-crank lever is pi votally connected to a bracket or frame beneath the car, to one arm of which, as f, a roller, f, is attached, the other arm, as f2, being connected by a connecting-rod, f", with one arm, as f3, of another bell-ciank lever pivoted to a bracket or trame,

f, the other arm of said last-na1ned hellcrank lever heilig loosely connected with a vertical rod which passes vertically through the platform oi' the car and is provided at its upper end with a rest or foot-plato to be acted upon by the foot of the driver.

As a car is passing along, thc tread-face of the wheel depresses the stud 7, and thereby turns the cross-bar 5 on its pivot, but othen wise effecting no result; but, if desired to turn the switch, the roller f is depressed, as herein sliown,by the foot of the driver, and it, acting upon the stud S sinuiltaneously with the action of the tread-face ot' the wheel upon the stud 7, depresses the cross-bar 5 and moves the bell-crank lever, to thereby move the rod or bar d longitudinally, swinging the pla-te or har c and turning the switch or tongue.

The rod or bar (l is connected with the bellcrank lever at the opposite side of the switch and is arranged and adapted to be operated in substantially the same manner as the bellcrank lever 2 i; so a detail description need not be given further than to say that in operation the rod d is moved in a direction opposite to the movement of the rod d', and hence serves to restore the switch when set by the rod d.

By employing two studs, as '7 S, located as shown and described, it will be observed that the switch cannot be operated by a passing vehicle.

In Fig. 5 the arm 4 of the bellcrank lever IOO 5 bar 5.

l. The switch or tongue and the longitudinally movable rods d d for moving,` it in opposite directions, combined with two verticallyiovmovable studs for each rod CZ d', pivotallyarranged cross-bars connected with the said rods and to which the studs are connected, the roller f', and means, substantially as described, for effecting its movement, all sub- 15 stantially as and fo.l the purposes specified.

2. The switch or tongue, the longitudinallymovable rods d d', and the pivotcd cross-bars o, connected with the rods or bars d d', coinbined with the studs downwardly movable independently or simultaneously, substantially as described.

3. The switch or tongue, the longitudinallymovable rods CZ d', the bell-crank levers and pivoted cross-bars, and the independently or simultaneously movable studs, combined with the roller f and means for moving it to cooperate with the car-wheel to effect the simultan eous movement of the studs, substantially as described.

In testim ony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
