shifted by a locomotive approaching the switch at the other end of the siding.

A further object is to employ locking means whereby the shifted switches may be held in the positions to which they are moved. Another object is to provide means for automatically unlocking the switches.

With the above and other objects in view the invention consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanyingdrawings, showing the preferred form of my invention, and in which- ,4

Figure 1 is a plan view of a switch located at one end of a siding. Fig. l isa similar view of the switch locatedat the other end of said siding. Fig. 2 is a section on line 2 2, Fig. 1. Fig. 3 is a detail view of the switch-shifting bar, and Fig. 4 is a similar view of the looking device. f

Referring to the figures by numerals of ref erence, 1 1 are the rails of the main line of a railway, and 2 2 are the rails of a siding. Switch-tongues 3 and 4 are pivotally mounted at the point of conjunction between the inner rails of the main line and the siding, and both of these tongues bear upon ashifting-bar 5 and at opposite sides of lugs 6 thereon and to which they are secured in any suitable manner. By this arrangementboth tongues are moved laterally simultaneously with the movement of the bar- 5. A spring'locking strip 7 isse'cured along the ou-teredge of the tongue 3 and has an arm 8 at the free end thereof which is adapted to lock the tongue against lateral movement and hold the switch open. A block 9 is located upon the springstrip at a point between its ends and extends upward to a point in horizontal alinement with the tread of the tongue 3 at a point near the fulcrum thereof. This block is adapted to be depressed by the wheels of a locomotive or car, and thereby force arm 8 downward below-the tongue 3. A spring 10 is interposed between tongue 4 and the adjacent rail 1, and when the arm 8 is depressed this spring eX- pands and throws the tongues 3 and 4 automatically, so as to close the switch and open the mainline A bell-crank lever 11 is pivoted to one of the ties 12, upon which the switch-tongues are mounted, and one arm of this lever extends over the spring-strip 7. A rod or wire 13 extends from this bell-crank lever to a second bell-crank 1ever14, pivoted upon av suitable base-plate 15, extending under the rails l and the spring-tongues 3 and 4. Abellcrank lever 16 is also pivoted upon said plate and is connected at one end to the bar 5,hereinbefore referred to. Locatedatapoint adjacent one of therails 1 and removed from the switchtongues 3 and 4 are standards 17, in each of which is fulcrumed a lever 18 and 19, respec-- tively. One of these levers 18 has a forked inner end 20, within which is fulcrumed a slotted inner end of the lever 19. Extending laterally from the outer ends of the two lovers 18 and 19 are pins 21, each of which is inclosed by a coiled spring 22, which bears upon a switch-oper'atingbar 23. This bar is secured to the pins 21 and extends longitudinally of the adjacent rail 1 and projects above the tread thereof. The end of the bar 23 which is farthest removed from the switch-tongues 3 and 4 is beveled, as shown at 24, while the opposite or inner end of said bar is curved outward, as shown at 25. The pins 21 move longitudinally within the levers 18 and 19, and such movement causes the springs 22 to become compressed between the levers 18 and 19 and the operating-bar 23. A socket 26 is formed at the outer end of the lever 19, and loosely mounted therein is a ball 27, formed at one end of a lever 28, which is fulcrumed in a suitable standard 29. A rod or wire 30 connects the other end of this lever 28 withone end of the bell-crank; lever 14,hereinbefore referred to. 1 7

All of the parts hereinbefore referred to have been described as being located at one end of a siding. Similardevices arelocated at the other end of the sidingand a wire or'rod '31 connects each bell-crank lever 16 with the bell-crank lever 14: at the opposite end of the siding.

The operation of the mechanism herein described is as follows: \Vhen a train approaches the switch illustrated in Fig. 1, the wheels of the locomotive will ride upon the beveled end 2i of the operating-bar 23 and depress said bar. This will cause the outer ends of the levers 18 and 19 to swing downward, and the inner end of the lever 28 will also be carried downward and cause the outer end thereof to move upward. Longitudinal movement will be imparted to the bell-crank lever let by the wire 80, and bellcrank lever 11 will depress sprin g-st rip 7, so as to bring the arm 8 below the tongue 3, and spring 10 will simultaneously expand and throw the tongues 3 and t laterally, so as to close the switch and open the main line. The movement of bell-crank lever 1% will also draw the wire 31, connected thereto,longitudinally, and as this wire is connected to the bell-crank lever 16 at the opposite end of the siding, as illustrated in Fig. 1, this bell-crank lever 1.6 will be moved upon its fulcrum and draw the bar 5 longitudinally, so as to open the switch, as illustrated in said Fig. 1. This movement will bring the tongue 3 oif of the arm 8, and said arm will spring upward and lock the tongues 3 and at. It will therefore be understood that a train approaching the switch illustrated in Fig. 1 will promptly pass on to the siding. When the train upon the main line reaches the switch shown in Fig. 1, its wheels will come in contact with the block 9 and depress the springstrip 7, and thereby remove the arm 8 from the path of tongue 3. Spring 10 will then promptly expand and throw the tongues 3 and 4 back to normal position. IVhen said train reaches the operating-bar 23, (shown in Fig. 1%) it will not depress the same, but will come in contact with the outwardly-extending end 25 thereof and move the bar 23 laterally, thereby compressing the springs 22 upon the pins 21. Then a train first reaches the switch shown in Fig 1 in approaching the siding, the operation hereinbefore described will be repeated at the other end of said siding. Eyes 32 may be arranged upon the plates 15 for the purpose of guiding the wires 30. It will be seen that the device is extremely simple in construction, and by providing an automatic switch-shifting mechanism of this character danger of collisions at siding is reduced to the minimum.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.
