To a/ZZ wlwwt t muy cora/cern:

Be it known that I, HARRY A. EARL, al citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Switch-Tongne-Operating Mechanism; and l hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable 1o others skilled in the -art to which it pertains to make and use the same.

. This invention relates to improvements in switch-tongue-operating mechanisms.

The object of this invention vis to provide x5 simple, reliable, and convenient mechanism whereby asWitch-tongue may be readily oper,- ated from a car or vehicle while the said vehicle is in motion.

With this object in view and to the end of 2o realizing other advantages hereinafter appearing this invention consists in certain features of construction land combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a top plan illustrating a portion of a main track, the end of a side track, a switch-tongue, a portion of a car or vehicle moving upon the main track from a direction opposite to the di- 3o rection in which the said tongue point-s and mechanism whereby the said tongue can be operated from the said vehicle while the latter is in motion. Fig. 2 is a side elevation, largely in vertical section, on line 2 2, Fig. l. Fig. 3 is a top plan, in horizontal section, on

line 3 3, Fig. 2. Fig. 4 is a transverse vertical section on line et 4, Fig. 2, looking in the direction indicated by the arrow. Fig. 5 is a top plan corresponding with Fig. 3,except that 4o in Fig. 5 the switch-tongue-operating lever is shown as having been actuated by the leveroperating shaft of the car or vehicle, and the lower portion of the said shaft is also shown. Fig. 6 is a side elevation of the lower portion of the shaft instrumental in actuating the switch-tongue-operating lever. Fig. is a vertical section on line 7 7, Fig. 6. Figs.

2, 3, 4, and 5 are drawn on a larger scale than Fig. l, and Figs. 6 and 7 are drawn on a still 5o larger scale.

y Referring to the drawings, a designates the rails of a main track, b the rails of a branch or side track,and c an ordinary switch-tongue, pivoted vertically' at its rear end, as at d, to any suitable support. The tongue cin Figs.

vl, 2, and 3 is shown in line with one of the rails of the main track and in Fig.5 in position to switch or guide a car or vehicle from the main track onto the side track.

The main track comprises a rail-section e, 6o which extends from in under the switch.- tongue c in the direction in which the said tongue points and a suitable distance beyond the forward or free end of the tongue. The rail-section e is provided interiorly with a chamberf, which extends longitudinally of the said rail-section.

A lever h is arranged within the chamber f and extends longitudinally of the said chamber. -The lever h is fulcrumed vertically, as 7o at g, near its central portion and centrally between the ends of the chamberf to thetop wall ofthe said chamber. The lever h is operatively connected at one end with the forward end ofthe switch-tongue c, and a pivotal pin la, which establishes operative connection between the said lever and the switchtongue, has preferably a screw-threaded upper end and is screwed into` a correspondingly-screw-threaded hole formed in the said 8o tongue, and removablyattached, therefore, to the tongue. The pin extends from within the engaging holeZ in the lever h through the top wall of the chamber f, and the said hole is elongated longitudinally of the lever to' accommodate the lateral swinging of the lever during the actuation of the switchtongue, and the top Wall of the chamberfis slotted, as at rm, to accommodate the location of the said pin during the operation of the 9o lever.

The lever h is bifurcated forwardly of the fulcrum of the lever, and the two arms n of the bifnrcated forward portion of the said lever extend forwardly of the said fulcrum and are arranged approximately parallel and longitudinallyof the upper portion of thechamberf. Each arm In is provided at its forward or outer end with an incline o, which faces forwardly and laterally inwardly. Obviously, roo

therefore, the two inclines o of the lever-arms fa diverge forwardly or outwardly longitudinally of the lever.

The rail-section e forms a case containing the lever h, and the interior chamberf of the said case is wide enough to accommodate the location and operation of the bifurcated porltion of the lever.

The rails of the tracks, including the railsection orv case e, are grooved on top and longitudinally, as at p, to form a way for the flanges of the wheels of cars or vehicles propelled or driven on said tracks, and the top wall of the chamber f is slotted vertically and longitudinally7 as at fr, to accommodate the extension into the said chamber of a vertically-arranged shaft A, which is employed in the operation of the lever h and carried by the forward end of the car or vehicle V, shown approaching the switch-tongue in Figs. l and 2. The shaft A extends through the ioor B of the forward vestibule or platform of the vehicle V, having lateral bearing in a vertically-arranged box D, which is secured to the said floor. The shaft A has lateral bearing also, a suitable distance above the door B, in a vertically-arranged box E, which is forme-d upon a bracket F, rigidly secured to the vertically-arranged dashboard or wall I of the vestibule or platform. The shaft A extends a suitable distance above the bracket F and at or near its upper extremity is operatively provided with a hand-lever C for oscillating or turning the shaft. The shaft A is provided a suitable distance above the Hoor B and below the bracket F with a laterally-projecting pedal-forming arm H, which is fixed to the shaft, preferably by a key J. The shaft A also has lateral bearing in a hanger K, which is secured to the under sideA of and depends from the floor B. The shaft A is provided at its lower end and below the hanger K with a laterally-projecting arm L..

The shaft-arm L is provided at its outer end with a depending member M, which at its lower end bears a horizontally-arranged roller N. The shaft A is shiftable vertically and is held in its upper and normal position by a spiral spring P, which is coiled upon the shaft between the bracket F and the pedal H, being attached at its upper end to the said bracket and at its lower end to the said pedal. Obviously', therefore, the shaft A is lowered against the action of the spring P upon bearing downwardly upon the pedal H, which is within convenient reach of the foot of the motorman or operative of the car or vehicle.

The lever C, pedal H, and shaft-arm L are in the normal position of the shaft A arranged parallel with the slot @which is formed in the top wall of the case e and arranged below and communicates with the way p in the top of the said case. The shaftA is small enough in cross-section to render it capable of entery ing the wayp and of passage into the chamberf of the case e through the slot r. As a car or vehicle V approaches the forward end of the slot r the motorman or operative of the vehicle lowers the shaft A by placing his foot and bearing downwardly upon the pedal H, so as to lower the shaft and bring the lower and roller-bearing end of the shaft into the adjacent groove or lway p ready for passage through the slot rinto `the chamber f as soon as the said end of the said shaft has passed to and over the forward end of the said slot, and the operative as soon as the shaft A has been lowered into the said chamber oscillates or turns the shaft in the required direction, as will hereinafter more clearly appear. In the lower position of the shaft A the pedal H rests upon the box D, which therefore forms a stop to limit the downward movement of the shaft.

In dotted lines, Fig. 2, the shaft A is shown in its lower position, with its arm L arranged within the slot r. The slot r extends from a point near the forward side of the fulcrum g of the lever h at the inner ends of the arms n of the said lever forwardly a suitable distance beyond the outer or free ends of the said arms. The slot 1' from a point adjacent the inner or rear ends of the inclines o forwardly to and a suitable distance beyond the forward or outer ends of the said inclines is wider next below the connected way p than the said way and extends laterally of the said way in both directions, and consequently in under the tread of the rail-section or case e. The slot r therefore accommodates an oscillation of the shaft A in either direction in the lower position of the shaft, in which position the shaft-arm L is in position partially in the said slot below the said way jp and partiallyin the chamber j' below the said slot, and the top wall of the chamber f may be said to be cut away to accommodate the lowering of the shaft into the said chamber and to accommodate the oscillation of the shaft in its lower position. The incline-forming outer end of the one or the other arms n of the lever h extends in under the slot r, according as the lever is in the one or the other of its two positions, and the incline-forming end of the outer arm n or the incline-forming end of the inner arm n of the said lever extends in under the said slot,according as the switchtongue is in position in the line of the main track,as shown in Figs. 3 and 4E, or in position to switch or guide a car or vehicle from the main track onto the side track, as shown in Fig. 5.

The arrangement of the parts is such that the incline o of the llever-arm n which projects in under the slot 'r shall be in the path of the outer end of the shaft-arm L when the shaft A is oscillated in the direction of the said arm upon actuating the shaft into its lower position, and the operative ofthe vehicle V upon lowering Ithe shaft into its lower position preparatory to the operation of the lever h by the shaft-arm L will oscillate the shaftin the one direction or the other, accord- IOO IIO

ing as the one or the other of the arms n of the said lever projects in under the slot fr.

The slot r is gradually reduced widthwise in both directions, as already indicated, where it becomes wider than the connected way 29, and each side wall of the said slot at a point where the said slot is increased in width forms, therefore, astationary laterally and inwardly facing incline t, which slopes forwardly and laterally outwardly. The inclines t, formed upon opposite side walls of the slot r,converge, therefore, in the direction of the rear end of the slot and are arranged between the inner ends of the inclines o and the rear end of the said slot, and the arrangement of the parts is such that the said inclines t are arranged in the path of the upper portion of the shaftarm L when the shaft A has been oscillated laterally in the lower position of the shaft, and consequently the shaft A is positively oscillated into the position required to accommodate the withdrawal of the said shaft from its lower position, being thus operated by the one or the other incline t, according as the shaft-arm has operated upon the one or the other of the lever-arms n.

The top of the rail-section or case e at the bottom of the way p of the said case is provided with a stationary upwardly-facing inclne te, which is arranged longitudinally of the said case between the lever-arms n and slopes downwardly and forwardly from a point in close proximity to the forward side of the fulcrum g of the lever h. is arranged in the path of the roller N of the shaft-arm L when the shaft is in its lower position, and the arrangement of the parts is such that the incline c shall have commenced to operate upon the shaft and begun to lift the said shaft immediately upon or somewhat before the completion of the operation of the shaft by the one or the other of the inclines t.

The spring P, acting to retain the shaft in its upper and normal position, as already indicated, obviously is placed under torsional strain in oscillating the shaft preparatory to the operation of the lever h and then acts to oscillate the said shaft into its normal position, and the shaft may be manipulated by the operative of the vehicle V in returning the said shaft into its normal position; but in any event the side inclines t and the upwardly-facing central incline a; afford means for positively effecting a return of the said shaft into its normal position upon the operation of the lever h by the said shaft.

The upper portion of the case e consists, preferably, of a piece which is removably secured by means of screws y to the lower portion of the said case.
