SWITCH-OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 506,218, dated October 10, 1893.

Application filed October 26, 1891. Serial No. 409,883. (No model.)

To all whom it may concern:

Beit known that we, WLADIMIR FARANOW- ski and FRANZ GUNIEwIcz, subjects of` the Emperor of Austria-Hungary, residing at Podhajce, in the Province of Galicia, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Switch-Operating Devices; and We do hereby declare the following to be afull, clear, and exact descriptlon of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,'reference being had gineer, the lever or levers controlling the switch operating devices being located between vthe rails.

AThe devices that act upon and move the switch operating lever or levers may be operated either by a motive fluid, as for instance, live steam taken from the locomotive boiler, or by compressed air supplied by the pump that compresses the air for the brakes, or by hand, as will now be fully described, reference being had to the accompanying drawings, in which- Figures l and 2 are end elevations of so much of a locomotive as will be necessary to illustrate our invention in its application to a locomotive, said figures illustrating switch operating devices controlled by a duid and by hand, respectively.

Referring to Fig. l in which We have shown two steam operated pistons whose rods are adapted to be projected into the path of the switch-operating lever orlevers so as to throw the same in one or the other direction to position the switch relatively to the direction of motion ofthe locomotive; A, and A indicate two piston cylinders suitably connected with the steam space of the locomotive boiler, each of said cylinders containing a piston, P, the rods B, and B 0f -which are of such a length as that when fully projected they will be in a position to engage the switch lever, said short arms or a wedge-shaped lever, can bev employed. Each rod is preferably provided at its lower end with a conical anti-friction roller, as shown, and for purposes well understood, and the pistons P are each provided with an inwardly opening valve V.

The piston rods B, and B are respectively vconnected by means of connecting rods C, and C', to the outer end of the arms of a lever D, pivoted at D', between the piston cylinders, said pivot carrying also a crank D2, shown in dotted lines and located in rear of the supporting plate for the piston cylinders. The crank D2 engages the upper forked end of a lever E, with which are pivotally connected two pistons, e2 and e', that abut against springs E2, E. If, for instance, steam is admitted to piston cylinder, A the piston and piston rod B will be moved downward to bring the roller end of the rod in position for engagement with one arm or side of the switch lever, whereby said lever is moved to change the position of the switch. At the same time vthe piston rod` B is moved upwardly, thereby compressing the air in cylinder A, which acts as a cushion for the piston in cylinder A', the spring E2 being simultaneously compressed by the action of the lever D, and crank D2 upon lever E, and said spring also acts asa cushion for the said piston in cylinder A. As the piston cylinder A cools, the steam supplied thereto condenses, thereby producing a partial vacuum, which causes the valve V in piston P of said cylinder to open, allowing the water of condensation to escape, and admitting air above the piston, both piston cylinders being open at their lower ends. The piston in cylinder A', being now relieved of pressure, the compressed spring E2 will exert its power upon lever E, and the latter upon lever D,`to move the same into a horizontal position, thereby ICO B will be at such an elevation as to clear the switch operating lever. The last named le ver may also be operated by devices con trolled by a hand operated mechanism, as shown in Fig. 2, in which rods F, F having at their lower end a roller or a shoe c2, c3, respectively, and sliding in guides m, n and m', n. respectively, are also connected by means of connecting rods C and CLwith the arms of the lever D, whose crank D2 is connected with a bell-crank lever h', by means ot' a connecting rod h3, and to said bell crank lever is connected a lever 71, that is operated by a rod h, extending to the engineers cab. The operation of these devices will be readily understood, the actuating mechanism causing the rods F and F to move simultaneously in opposite directions,and when the operatinglever 7L is brought to` a given normal position the lever D will be moved to a like normal horizontal position to hold both rods F and F clear of the switch operating lever.

I-Iaving thus described oui-invention, what` we claim as new therein, and desire to secure by Letters Patent, is-

l. In mechanism for operating railway switches from a moving train, the combination witha vehicle of such train, of coupled rods adapted to engage with and displace a switch lever, said rod-s movable reciprocally in converging planes, and` means for imparting motion to said rods.

2. Inl mechanism for operating railway switches from a moving train, the combination with a vehicle of such train, of coupled recprocally movable rods adapted to` engage with and displace a switch lever, and means for imparting reciprocal motion to the rods and for automatically returning the saine into their normal position when moved out ot it.

3. In mechanism for operating railway switches from a moving train, the combination with a vehicle of such train, of two cylinders, their pistons and piston rods, said rodscoupled to :nove reciprocallyand adapted to engage with and displace a switch lever, and means for admitting fluid under pressune to the cylinders on one side ct their pistons, for the purpose set forth.

4. In mechanism for operating railway Switches from a moving train, the combination with a vehicle of such train, of two cylinders their pistons and piston rods having their longitudinal axes in converging planes, said rods coupled to move reciprocally, and means for admitting a fluid under pressure on one sideof the pistons, forthe purpose set forth.
