SPECIFICATION forming part of Letters Patent No. 663,595, dated December 11, 1900.
Application filed March 5, 1900. Serial No. 7,317. (N model.)
To a/ZZ whom it may concern:
Beit known that I, AMos YOUNG-BLOOD, of North Augusta, in the county of Aiken and State of South Carolina, have invented a new and useful Improvement in Operating Railway- Switches, of which thev following is a specification.
My invention relates to that class of railway-switches automatically operated by the railway rolling-stock, and has for its object certain improvements in the construction of the switches and the operating means therefor whereby the setting of the switch is always properly insured and the possibility of wreck on account of an open or misplaced switch is precluded.
The invention consists in certain details of construction and arrangements and combinations of the parts of the switch and the automatic operating means therefor', which I shall hereinafter fully describe and claim.
Reference is to be had to the accompanying drawings, forming part of this specification, in which like characters of reference indicate corresponding parts in all the views.
Figure lis a plan View of a portion of a railroad-track,illustrating myinvention. Fig. 2 is a transverse section thereof. Fig. 3 is a sectional plan view of the devices for manually setting the switch. Fig. 4 is a side View of a locomotive provided with my improved automatic switch-operating devices. Fig. 5
Fig. 6 is a detail enlarged face view of the switch-operating devices. Fig. 7 is avertical section on the line 7 7 of Fig. 6, and Fig. 8 is a section taken on the line 8 8 of Fig. 6.
Referring to the drawings, 10 designates a section of the main track, and 10n the siding, arranged for connection to the main-track rails by means of the pivoted switch-tongues 10b. Between the main rails are pivoted two frames 11, formed with inclined or converging sides 11a and placed with their narrow ends abutting and pivotally connected to the opposite sides of the switch-bar 12. The sid es of these frames serve as cam or inclined surfaces which are adapted to be engaged by a part of the switch-throwing mechanism hereinafter described to direct a train onto the siding or to allow it to continue upon the main track.' The switch-bar 12 is provided with a side extension 12, extending to a manuallyoperated switch-rod 13, which, as shown in Fig. 2, is rotatably mounted in a suitable casing 13 and has a crank 13b, adapted to enter a notch 12b in the switch-bar extension 12a when it is desired to manually throw the switch, and to lock the switch in either position a lock 14 is provided in the casing and is adapted to engage either one of the notches or keepers 12c in the said extension.
In order to insure the proper position of the switch-tongues 10b when a train is on the siding and intends to return to the main track, the opposite end of the switch-bar 12 is formed with a shoulder or stud 12d, whereby it is adapted to be engaged and moved into proper position by one arm of a bell-crank lever 15, connected by its other arm to a forwardly spring-pressed slidable rod 15, the rear end of said Vrod being connected by a T-lever 15" to a link 15C, extending across to the siding, as shown, and there connected to an operating-lever 15d, havinga roller 15e mounted on its free end. The said roller is adapted for engagement by the same. operating mechanism described below, which engages the inclined g-uiding-frames 11. This operating mechanism is adapted to be located in the front of the locomotive Aand to be actuated in the locomotive-cab B, and it consists of the following parts: On the front of the locomotive A are iixedly secured spaced-apart transversely-extending guide-rods 16, on which, by means of sleeves 17, a vertically-flanged plate 17 is iitted to travel, and held on said plate by the flanges thereof is a slide 18, on which an arm 18 is pivoted, the lower end of said arm passing through a loop 18b on the slide and carrying at its lower bent end the switchoperating roller or disk 19, which is adapted to ride against the inclined sides of the frames 11, as described above. Springs 19CL engage. each side of the arm 18, as shown, to allow the roller t-o compensate for slight differences in the positions of the frames with respect to the track-rails in different switches.
As shown particularly in Fig. 5, an arm 2O extends laterally from the plate 17 and is formed with a projection or pin 20a, fitted in the recessed shank of the rocker 21, the latter being formed with a seat 21a for an eccentric 22a on the end of a rotatable shaft 22. The
said shaft extends back into the cab B,where it is provided with a pinion 22", meshing with a toothed wheel 23 on a shaft 23, which latter is operated by the hand-lever 24, arranged for engagement with the quadrant 24a.
It is evident that a movement of the lever will rotate the shaft 22 and cause the rocker 21 to move the roller 19 to the left or right to throw the switch. The quadrant 24 is formed with three notches. When the lever engages the upper, the roller will throw the switch s0 that the engine will take a siding to the left. When it is in the lower notch, the engine will take a siding to the right, and when it is in the middle notch the roller will put the frames 11 directly in the middle of the track, thus causing the train to keep the main track and correctly placing any misplaced switch.
It may be desired to throw the automatic switch-operating mechanism out of operative position, and for this purpose I pivotally f mount a shifting-lever 25 above the guiderds 16, and in such lever is formed an elongated slot 25a, in which Works a stud 25h on the upper end of the slide 18. The free end of said lever is formed with a seat 25c for an eccentric 26 on a shaft 26, running back to the cab and there turned by a crank-handle 26". By thus raising and lowering the shifting lever the slide 18 may he moved vertically to raise the roller 19 above contact with the frame 11.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a railway-switch, the combination with the switch-tongues and their bar, of pivoted frames having converging sides arranged and adapted for engagement by the operating device on the rolling-stock, said frames being placed in the track with narrow ends adjacent each other and pivotally connected to opposite sides of the switch-bar, as set forth.
