Description
Patented Aug. 1, 1939 UNITED STATES PATENT OFFICE SWITCHING SYSTEM Philip Verplanck, Akron, Ohio Application February 21, 1938, Serial No. 191,647
7 Claims.
This invention relates to a switch system for double tracks of an overhead railway at the region of cross-over by other double tracks and has for its object to provide a switch system for switching a train on any track from either direction to either track and either direction on the intersecting tracks or to a cross-over position on its original track whereby the direction may be changed.
In the case of overhead rails it is very difficult if not impossible to arrange a simple switching system supported solely from the suspended beams from which the tracks are hung. It is also impractical to obtain the multiplicity of track connecting possibilities in a simple turn table without a large number of cross-overs which make for discomfort, noise and undue wear on the wheels, flanges and tracks. It is, therefore, the principal object of this invention to provide a compound switch comprising laterally shifting units and a rotating or turntable unit, each supported directly from the ground on individual track units and to provide coordinated actuating means for operation thereof.
Derailment of any rail vehicle is serious at high speed but derailment of an overhead rail vehicle may be fatal or quite costly even at low speeds so that when an overhead rail is disconnected at some point, safeguards against train operation in the vicinity are of utmost importance. It is, therefore, another object to provide a switch system, as above described, in combination with a power control system automatically operative in response to the relative position of the track portions which will preclude train operation unless and until the track sections are aligned and ready to receive the weight of a train.
Other objects and advantages will become more fully apparent as reference is had to the accompanying drawings wherein my invention is illustrated, and in which Fig. 1 is a plan view of my improved switch-system;
Fig. 2 is a side elevation of one of the laterally shifting units taken along the line 2-2 of Fig. 1;
Fig. 3 is a vertical diametric section of the rotating or turn table unit taken along the line 33 of Fig. 1;
Fig. 4 is a vertical section taken along the line 4-4 of Fig. 1 showing the track locking devices, and
Fig. 5 is a diagrammatic showing of a portion of the power control circuits.
More particularly, the double tracks I, la, 2,
' 2a,, 3, 3a and 4, 4a of an overhead rail system are shown in Fig. 1 as approaching the switching system from four directions. The tracks are suspended from overhead beams in any special or conventional manner (not shown), each track being shown as of the two-rail type although the invention is equally applicable to mono-rail tracks. The track sections of all of these tracks terminate at laterally movable units 5' each of which has two track sections 6 and I carried thereby for selective connection of the main track ends with a single stationary track section 8 which, in turn, is selectively connectible to the track sections 9, I0 and II of the turn table I2.
The units 5 are all of identical construction, one being illustrated in Fig. 2. The description of this figure, which is assumed to be the one carrying track sections 6 and I, is, therefore, descriptive of all of these units. The main base members I3 are supported by axles I4 each hav-' ing wheels I5 at each end thereof. The wheels rest on parallel rails I6 which runnormal to the direction of the main tracks I, la and which rest on the ground substantially below the tracks I, la. A wheel stop I! limits the travel of the wheels I5 at each end of the tracks I6, these tracks being only long enough to shift the section I into alignment with the track Ia and the section 6 into alignment with the section I. A motor I8 mounted on the base I3 connected to one axle I4 by the driving chains I9 serves as the prime mover for impelling all wheels. Arising from the base members l3 are vertical pillars 20 connected at their tops by the horizontal beams 2| from which webmembers 22 depend, these web members supporting the heavy beams 23 upon which the rails 1 are mounted. The third or power carrying rails 24 are also carried by the beams 23. The beams 23 are divided between the rails 6 and the rails I to permit passage of the train suspension means from the train trucks which ride the rails, the car bodies residing between the base I3 and the beams 23. The next unit to be described is the stationary portion 25 which carries the single stationary track sections 8. The exterior of this unit has wall portions 26 which, preferably, parallel and reside immediately adjacent the inner edges of the units 5. The interior is circular in order to receive the turn table I2. This unit 25 is supported directly on the ground and may be made of steel, concrete or any desirable materials and may be built with passenger waiting accommodations to serve as a station with facilities for loading and unloading the trains.
The turn table I2 has a base frame 26 supported on the wheels 21, 28 and 29, which run on circular tracks. Arising from the base 26 are pillars 30 which are connected at their tops by the horizontal members 3| from which depend structural portions 32 which support other horizontal beams which, in turn, support the track sections 9, l8 and II. The sections 9 and II are arcuate in plan view, thus serving to connect any section 8 with either adjacent section 8, and the section II] is straight for connecting any two opposite sections 8.
The safety system will now be described. In Fig. 5, the tracks 4 and 4a, are illustrated with the third power rails 24 therebetween, approaching the switching units 5, l2 and 25. At some dis tance, say twenty-dive hundred feet away from the switching units, power breaks or insulating interrupters 34 are inserted in the third rails and also in the tracks, if necessary, in order that the motors which drive the train can no longer receive power from the original source of power supply. The insulated sections 24a of the third rails can be energized from a shunt circuit or an entirely separate circuit 35 supplied from a power source 36.
Cooperating with each rail section 6 and with each rail section I is a slidably mounted plunger 3'! which may be the core of a solenoid 38 or the piston rod of an air motor 38, for instance, which passes through an opening 39 in the track supporting structure of the track I or la. When and only when a track section 6 or I is in alignment with its corresponding section I or la, the solenoid is energized by the closing of the switch 48 and the plungers 37 enter the holes 39. As they pass through their holes 39 the ends of the plungers 3'! engage a switch arm 4!, thus closing the circuit 35 and energizing the third rail sections 24a. The sections 8 and 9, H], II are also each provided with a similar solenoid, plunger and switch arm mechanism, as has just been described and all switch arms 4| are in the circuit 35, only two being illustrated in Fig, 5, so that every switch must be closed before the circuit 35 can operate to energize the motors of the train.
