.IOIIN R. GOODE, OF WASHINGTON, PENNSYLVANIA, ASSIGNOR OF ONE-FOURTH TO MILTON L. MORRISON, OF AMITY, PENNSYLVANIA.

RAILWAY-SWITCH.

To all whom it may concern:

Be it known that I, JOHN B; Goonn, a citizen of the United States, and a resident of Wvashington, in the county of Washington and State of Pennsylvania, have invented certain new and useful Improvements in Railwaywitches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to railway switches and more particularly to switches used in street-railway construction, and its objects are, to provide a switch which will be simple in construction eiiicient in its working and capable of being operated from the carplatform, thus over-coming the necessity of having to leave the car, as is now required by the use of old style switches.

IVith the above objects in view, I will now describe my invention, reference being had to the accompanying drawings, in which Figure 1, is a plan view of my switch the casing or housing being indicated by dotted lines. Fig. 2, is a side elevation of the same. Fig. 8, is a broken side elevation of the switch and car platform showing the operating mechanism attached to the under side of the car-platform. Fig. 4, is a broken front elevation of a car showing the operating mechanism more clearly and Fig. 5, is a side elevation of a modified form of operating mechanism.

Similar letters of reference indicate corresponding parts in the several views of the drawings.

A, 'represents the main-track and guardrail and B, the pivotal switch-tongue connected thereto, the .tongue being shown in full and dotted lines for illustrating the two positions thereof. Secured to both sides of the rail are brackets a, into which are pivoted sectional disks Z). Connected to these disks near their inner apex are links or bars c which are directly connected to the tongue B, by means of a pivot or bolt (Z. Connected to the opposite apex of the sectional disks are continuous rods or bars e, which in turn are connected to auxiliary levers f, which are pivoted to the sides of the main-rail. Pivoted in the rear of these auxiliary levers are the main trip-levers g, and g', which are slotted in their forward ends and engage a pin or bolt in the upper end of the auxiliary levers Lugs or pins i, is provided on the Specification of Letters Patent.

rail near the outer ends of the trip-levers for the purpose of limiting the downward movement of said levers, and lugs or projections c' and c", are formed on the top sides of these levers which are adapted to project up through openings in the top of the casings or housings j, the purpose of which will appear hereinafter.

Secured to the underside of the car-platform is a bracket 7c, which carries a bar Z, which is movably connected with operating trip-levers m, and m. These levers m, and m', project up through the platform and are provided with heads or shoulders a, and extend down through a guide plate 0, connected to the platform by means of braces p. The lower ends of these levers m, and m, are somewhat curved as shown and are provided with wheels g, which are adapted to engage with the lugs or projections c', for operating the switch mechanism as will be more fully described hereunder in the operation. Springs r, are employed for balancing the bar Z.

A modified form of operating mechanism is shown in Fig. 5, whereby I may employ a pivoted lever s, which is pivoted at its forward end to the underside of the car-platform and carrying a wheel t, in the rear or loose end, and having connected to it a trip lever u, which projects up through the platform. A spring o, is connected to the lever s, at one end and to the platform at its other end for the purpose of lifting and holding the said lever s, clear of the switch operating mechanism when not in use. Two sets of these levers s, and intermediate mechanism connected thereto are employed at each end of the car.

The operation of the invention is as follows :-Assuming the switch mechanism to be in the position shown in Fig. 1, and it is desired to take the main track the trip-lever m, would be depressed by the foot, which would cause the wheel in the lower end of the lever to come into contact with the lug or projection z', which would depress the main trip-lever g, which in turn would push the auxiliary lever downward thereby drawing the sectional disk o, through the rod c back, which movement would draw the switch tongue B over into the position shown in dotted lines, Fig. 1. The next car desirn ing to take the switch would drop the opposite trip-lever, which through the corresponding mechanism would draw the switch Y section or tongue, cams pivoted to thesides of the main track and continuous rods or bars secured at one of their ends to said cams and at their opposite ends to and near the apex of the sectional disks, lugs formed on or secured to the sides of the rails for limiting` the downward movement of said cams, together with the elongated shells or casings bolted or otherwise secured to the rails for protecting the mechanism, all substantially as and for the purposes shown and described.

2. The combination in a switch operating mechanism for railways, consisting of the main and side tracks and pivoted rail sec-V tion or tongue, of brackets-secured to the sides of one of the mainV tracks, sectional connected therewith-links or bars, which in turn are directly pivoted to the switch tongue, bell cranks pivoted to the sides of the main rail and continuous rods or bars E connected with said bell cranks at one end g and 'with the apex .of the sectional disks at hereinbefore shown and set forth. disks carried by said brackets and having their opposite ends, together with trip-levers pivoted at one end to the main rail and engaging with the bell cranks at or near their opposite ends, together with housings or casings pivoted or otherwise secured to the rails for protecting the mechanism, all substantially as and for the purposes shown and described.

3. The combination in a switch operating mechanism for railways, consisting of the main and side tracks and pivoted rail sec-V tion or tongue, of brackets secured to the sides of one of the main tracks, sectional disks pivoted in and carried by said brackets having connected thereto links or bars, which in turn are pivotally connected to the rail section or tongue, bell crank levers pivoted to both sides of one of the main rails and connect-ed by means of rods or bars to the sectional disks at their opposite ends, trip levers pivoted to the main track the opposite ends of which are adaptedtoengage the `bell crank levers, housings secured to the track for protecting the herein described mechanism, together with the operating mechanism connected torandrwith the ear body or platform consisting of the parts specified, all substantially In testimony that I claim thegforegoing as my own invention, IV have hereunto set my l hand in the presence of two witnesses.
