AUTOMATIC RAILWAY-SWITCH.

SPEGIFECATION forming part of Letters Patent No. 546,051, dated September 10, 1895.

Application filed May 23, 1894. Serial No. 512,174. (No model.)

To all whom it may concern.

Be it known that 1, WILLIAM J. MoFAR- LAND, a citizen of the United States, and a resident of the city and county of New York,

State of New York, have invented certain new and useful Improvements in Automatic Railway-Switches, of which the following isa specification, reference being bad to the accompanying drawings, forming part hereof.

This invention relates to switches for railways or tramways, and has for its objects to provide improved means whereby a reliable automatic action may be had, and whereby the switch may be operated either by a part projecting from a moving car or by the weight of the horses that draw a car.

In the embodiment of my invention herein particularly explained the switch is constructed so as not only to control the point or points of movable rail or rails of the 7 track, but also to control a point whereby the slot of a conduit-railway (such as a cable railway or an electric railway receiving its current from underground conductors) is switched so that not only will the car-wheels be guided in the desired direction and prevented from going in any other direction, but the arm projecting downward through the slot will be also thus guided.

The accompanying drawings illustrate an embodiment of my invention on a road adapted for a cable propulsion.

Figure 1 is a plan view of a portion of a cable-railway track and turnout or siding or branch, showing the switch-points in'position to direct the car along the main line and to prevent it from turning into the branch. Fig. 2 is a plan view of the switch-operating mechanism located below the surface of the ground 40 and in the conduit. Fig. 3 is a vertical longitudinal section of the road-bed, conduit, and operating mechanism. Fig. 4 is a vertical transverse section of the same, taken on the line 4 4, Fig. 3.

The construction of the frame supporting,

the road-bed and of the underground tunnel or conduit is not particularly shown, since the same forms no part of this invention, and may be of any of the usual constructions employed in cable railways, as well understood by those skilled in the art. The tracks a a and the covering portions or plates b b of the conduit and the frame for supporting the same may be of any usual and well-known pattern, provided that sufficient space be allowed underground for the operating mechanism of my improved automatic switch. The slot is shown as formed centrally between the tracks, and the arm 0,

'which is attached to a car in any usual and suitable manner, projects downward through this slot and is provided with suitable means for gripping the cable d. Only a short portion of this cable d is shown in the drawings, but it will be understood that it may extend either along the main line or out on the branch, or may not extend further than the switch, and that supplementary cables may be provided along either the mainline or branch line, as desired. The grip will be of any usual and suitable construction, and may be provided with the usual and well-known cable-ejector, so that it may be caused to throw out the cable at anytime, all as well understood in the art. The means for actuating the automatic switch from the cable car consist of the 7 striker-arm e, fitted to slide vertically upon the grip-arm c and controlled by a rod 6, which may be operated directly or by suitable connectinglevers, so as to be moved into two different positions. The lower of these 8.: positions is shown by the full lines in Fig. 4, while the upper of these positions is indicated by the dotted lines in the same figure. In the lower position the striker-arm will turn the switch into the position shown in Fig. 1, so as to direct the car along the mainline, and in the upper position the striker-arm Will turn the switch so as to direct the car along the branch or turnout. The parts with which the strikenarm e engages consist of the opcrating-arm f, extending from the vertical shaft f, suitably held to oscillate in vertical bearings, and the operating-arm 9, extending from another vertical shaft 9', also fitted to oscillate in suitable bearings, and these two 5 shafts f and g are connected together so that the rotation of one will cause a corresponding rotation of the other, but in the opposite direction, by means of the meshing gear-teeth on the disks f and g fitted upon the shafts f and g, respectively, or by other suitable connecting means. When the strikerarm 6 is set in its lower position, as shown in the full line, its operation is to move the opcrating-arm f into the oblique position shown, and when the striker-arm e is set in the upper position its operation is to move the operating-arm 9 into an oblique position corresponding to that shown as occupied by the armf, and this movement of the arm g operates through the connections of the two shafts f and g to throw the arm f back again into a position corresponding to that shown as oocupied by the arm g. Thus it will be seen that the. operation of either one of the arms f and g by the striker-arm c throws the other arm back into position to be operated upon.

The connections of the shafts f and g to the point-actuating mechanism are shown as consisting of adjustabie connecting-rods h h, each pivoted or otherwise joined at one end to the disk 9 or other part connected with the shafts f or g, and each pivoted or otherwise joined at its other end to a disk or plate h, or other part of a vertical shaft 1', fitted to oscillate in suitable bearings, and connectingrodsjj, each pivoted or otherwise joined at one end to an arm projecting from the vertical shaftt'and at the other end to an arm projecting from the vertical shaft 70, which shaft is is also fitted to oscillate in suitable bearings. The rods 7t h and jj are shown as adjustable, so as to provide for adjusting the parts and maintaining the proper tension of the rods. It is of course evident that other connecting means may be employed for imparting the movements of the shafts f and g to the shafts t' and 7c,but the means shown are peculiarly adapted for the purposes and functions of this structure.

The track-point Z (shown in Fig. 1 and indicated by dotted lines in Fig. 2) is suitably pivoted and has a downwardly-projecting pin or stud Z, which works against a cam-surface or into a cam-slot formed in a disk or plate 1'', secured or formed upon the vertical shaft 1', and this cam or slot is so shaped that the oscillation of the plate and shaft 2" 91, caused by the operation of the shafts f and moves the stud Z toward and from the axis of the shaft 1., and thereby moves the switch-pointl into one or the other of its positions, as desired, and also firmly locks and holds the switch-point in desired position. The slotpoint m, also shown in Fig. 1 and indicated by dotted lines in Fig. 2, is suitably pivoted and has pivotally connected to it an arm n, which is pivoted on a stud n and connected at one end to the slot-point m through the pivot-pin on, while at the other end it has a pin or stud n working in a slot or groove formedin the disk or plate which plate It" is secured to or formed upon the vertical shaft is, and the oscillations of the vertical shaft 70 and its disk 70' cause the pin 973, working in the slot of said disk 70', to move the arm n, and the arm 01, through the stud m, to actuate the slot-point m and to move the slotpoint m into one or the other of the two desired positions thereof; and this mechanism, when at rest, holds the said point min either one of said positions.

The operation of the automatic switch as caused by the projecting striker-arm 6 will be evident from the above description. When the striker-arm e is set in lower position and passes by the operating-arm f, it will move said arm f into the position shown, and the shafts f, g, t', and 7c will all assume the positions shown and the switch will be set to guide the car along the main line, and the operating-arm g will be set to the position shown. When the striker-arm e is set into upper position and passes by the operating-arm g, it will actuate said arm 9 and the shafts f, g, i, and 70 into their other extreme position and will move the points so as to guide the car along the branch or turnout, and will, at the same time, set the operating-arm f back again into position to be operated by a strikerarm 6 when properly adjusted for operating it. Thus the gripman is enabled to set the striker-arm 6 so that it will operate the switch mechanism to guide his car in either path that he may desire, and if the switch mechanism is already in the desired position the striker-arm will pass by withoutoperating it, but if the switch mechanism is not in the desired position, it will necessarily bein the position to be operatedby the striker-arm, and the striker-arm in passing by will set the switch so as to properly guide the car.

The means for operating the switch by the weight of the horses of a horse-car is shown as consisting of the two movable platforms 0 and 0 (indicated by dotted lines in Fig. 2) and placed at opposite sides of the track, so that the horses may be guided to operate either one or the other at the will of the driver. These movable platforms are connected, respectively, by downwardly-extending connecting-rods p and p to the pivoted disks p and 19 respectively, and the two pivoted disks 19 p are joined by the connecting-rod q, so that the downward movement of the platform 0' causes a corresponding upward movement of the platform 0, and vice versa, and the movement of either causes a longitudinal movement of the connecting-rod q, (see Fig. 4) the downward movement of the platform 0 causing the rod q to be pulled toward the disk 19 and the downward movement of the platform 0 causing the rod q to he pulled toward the disk p The connecting-rod q is connected to or caused to suitably engage with a part projecting from the vertical shaft t'as, for instance, by thelateral arms q q, as shown embracing an arm '6 extending from said shaft. This connection of the connecting-rod q, and the vertical shaft 2' causes the longitudinal movement of said rod q to produce an oscillation of said vertical shaft i and of the other parts of the switch-operating mechanism and the switch points connected therewith,

and thus the'movement of the platforms 0 and 0' produces a setting of the switch points and of the various parts of the switch-operating mechanism, the downward movement of the platform 0' setting the switch points to guide the car along the main line, and the downward movement of the platform 0 setting the switch points to guide the car along the branch.

From the above description it will be evident that my improved automatic switch is adapted to be used upon a road carrying cars propelled by horses and on a road carrying cars propelled by cables or any other power,

and also on a road carrying some cars propelled by horse-power and others propelled by cables or any other power. It will of course be evident'that it is not essential that the switchoperatingmechanism be located underground, although that arrangement is highly desirable upon any line of railway where a conduit is employed, and may be desirable upon other kinds of rail or tram ways. It is also evident that parts of my invention may be employed separately or in connection with other parts of difierent constructions, and I do not therefore limit my invention to the particular construction described herein and shown; but
