IMPRovED RAmwAY- swrrca The Schedule referred to in these Letters Patent `and making part of the same.
1' o all whom' tt conce/m:
,of` the construction and operation of the same, reference being had tothe annexed drawings forming a part of this specification, in which- Figure l represents a perspective view of the railroad-switch chairs, as constructed when applied to two side tracks;
Figure 2 represents a perspective view of the railroad-switch chairs, as constructed when applied to one side track; l
Figure 3 shows a plan of the railroad-switch chairs, as constructed for t'wo side tracks; and p Figure4 represents a plan of the railroadswitch chairs,- asconstructed for one-side track, and details of two rails common to both chairs, and marked e and fr.
The chair A, figs. l and 3, consists of an iron plate, cast with the` raised rails a, b, and -v, shaped, constructed, and arranged as shown in thedrawings.
The ,rail t and wedge-shaped portion of the rail b aresecured from the wear of oar-wheels bya covering of steel plate riveted to the rails, asshown in o, iig. 4.
In front of the pointed or narrow end of the rail b of the `chair A, digs. 1 and 3, is a groove, X, cut through the entire thickness of the plate, and of sufficient size to admit the free lateral motion of the bolt extending from the under portion of the rail fr, fig. 4.
The rail lr of chair A, gs. l and 3, consists of a rectangular bar of cast or wrought-iron, secured to the plate by a movable bolt or pivot,`which is held in its place by a-nut at its lower end. The opposite end of the rail a' is movable over the groove X by,a bolt passing through it, with a thread out at its lower end, and riveted to the rail, if the rail is of wrought-iron, and secured Vin the rail, if of cast-iron, while being cast. The movable rail r can be adjusted to the main or side track at pleasure, by the switch-lever, which moves the 'arm L, to which said rail is attached by the projecting-,bolt and secured by a nut.
The chair A', figs. l and 3, consists of a cast-iron plate with raised' rails a, b, o, and o, constructed and arranged as shown in the drawing. L
The upper surface of the rails e o is protected by steel plates .similar to those previously described, and shown in fu, iig. 4.
Y The rail lr is of the same size, and constructed and applied similarly to the rail 'r of chair A, figs. 1 and 3, as shown in detail in fr, iig. 4.
' Figs. 2 and 4 represent the chairs, as constructed when applied to one side track.
The construction and arrangement of the wedgeshaped rails Iu o and movable rail fr are similar to those of the lower end ofthe chairs A and A', figs. l and 3.
The rail a in chair A, figs. 4 and 2, terminates at the point. Itis represented to angle to the left in figs. 1 and 3, and it connects directly with the maintrack rail M.
The application of chairs, g. 3, to two side tracks is explained by the fact that the momentum of a car or train moving on a straight line vtends to keep it moving in the same direction, unless prevented by an obstruction. e
If, then, the movable rails r fr are adjusted to the main-track rails M M, the oars coming from either direction can move straight without obstruction. The wheels passing over the wedge-shaped rails o o will, when. over their narrowest point, rest partly on the rails adjoining them. on the same principle which allows them topass over raiiroad-frogs in ordinary use. Upon the same principle, oars coming from side tracks will `move upon the main track, their wheels being guided by their flanges, as on ordinary curves.
The advantage gained by the use of these switchchairs consists in the saving of time usually occupied in stopping and switching when moving, from side to main tracks.
When moving from the main track toward a switch, cars are guided to the right-hand side track' by the switch-lever, which moves the 'rail r of chair A, figs. 1, 2, 3, and 4, andto the left-hand track by the lever connected with the movable rail fr of the chair A of the same figure.
Should either of the movable' rails lr c' be left'adjusted to the wrong track, the danger of cars being thrown oil' the track, would `be materially less than on an ordinary switch, there being in this combination of chairs always one raiLconnected in direct line with the main track.
Claims.
1. I claim the plate of the switch-chair A, cast with the groove X, and the raised rails a b o, and provided with the movable` rail r, all arranged as described for the purpose specified. A
2. I also claim the switch-chairs A and A, figs. 1 and 3, as constructed, combined, and applied to one main and two side tracks, and the chairs A and A', jigs. 2 and 4, as constructed, combined, and applied to one main and one side track, as herein set forth.
