RAILROAD SWITCH. No.-349,250. Patented Sept. 14,1886.
WITNESSES UNITED STATES PATENT OFFICE.
CHARLES M. CROSBY, OF HILLSBOROUGH, OHIO.
RAILROAD-SWITCH.
$PECIPICATION forming part of Letters Patent No. 349,250, dated September 14, 1886.
Application filed January 12, 1386. Renewed August 23, 1886. Serial No. 211,647.
To all whom it may concern:
Be it known that I, CHARLES M. ORosBY, of Hillsborough, in the-county of Highland and State of Ohio, have invented certain new and useful Improvements in Railroad-Switches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of thisspecification, in which- Figure 1 is a plan view of a section of railroad-track having my improved switch applied, showing the main track open. 2 is a similar View of a portion of the track, showing the siding open. Fig. 3 is a det-ailsectional view of the switch-block.
The invention relates to improvements in that class of railway-switches in which a sliding frog forms part; and its object is to provide such a switch of simple construction, of efficient action, in which the main line and siding may be both closed, and in which, when so closed, the wheels ofacar passing from the siding to the main line will not have to ride over the frog.
Theinvention consists in the construction and novel arrangement of parts hereinafter described, and pointed out in the app ended claims.
Referring to the accompanying drawings, A A represent, respectively, the inner and outer rails of the main line, and B B the inner and outer rails of the siding. Where the lines of rails A B cross each other the rails are cut away, so as to make a space, 0, of suitable length. of said space toward the switch-lever are not in contact, but have between them the space 0, wide cnoughfor the flange of a wheel to pass, as shown.
D is a bed-plate arranged to slide transversely with relation to the main track in ways secured to the tics or in recesses formed therein.
The bed-plate is just wide enough to fit in and slide easily through the space 0 in the rails A B.
e is a switch-rod, which connects the bed plate with one arm of the crank-lever E. The other arm of said lever is connected with a similar crank-arm, E, by the rod 6 and the switch-rod e connects the other arm of E with the switch-rails and switchstand.
The ends of the rails A B 011 the side (No model.)
of the rail A.
Between the grooves which run into each other at their ends f on the side 011 which the main track and side track approximate, the upstanding portion H of the bed plate is necessarily Vshaped, one side being parallel with the main line and one with the siding. The point h of said portion lies toward the side on which the tracks approximate, and the base h on the other side is just wide enough to have one side coinciding with the inner side of the rail A and have one side coinciding with the inner side of the rail B when the bed-plate is in the position shownin Fig. 1. WVhen the bed-plate is slid in, as shown in Fig. 1, the part G will coincide with the rail A, setting the frog to the main track and closing the siding, so that a train cannot pass therefrom. When the bed-plate is slid into the position shown in Fig. 2, the part G is inward from the rail A and the part H lies in the space O, so that both lines are open and a train can pass either Way on the main track and from the siding onto the same. If desired, the grooves might be dispensed with and the parts G and H might rise directly from the bed-plate; but the grooves are preferable, as they act as guardrails to the flanges at the break in the line.
Any other form of switch-lever or device to move thebed-plate may be used.
K K are guardrails respectively upon the main track and siding, to prevent derailment at the point C.
It is evident that the invention can be used either with the class of split switches or with the class of stub-switches.
The rod 6 is connected to the rails A B near 95 their ends adjacent to the switch-lever, the ends of the said rails near the siding bed-plate being secured to several ties, so that as the switchlever and rods 6 e are moved the rails A B close the main track and open the siding or the loo reverse simultaneously with the opening and closing of said tracks by the sliding bed-plate.
I am aware that switches have been made with a sliding frog forming part thereof, and such I do not claim, broadly; but,
Having described my invention, I claim 1. In a railway-switch, the combination of the inner lines of rails of the main track and siding cut away at their point of intersection, so as to form a space of desirable length, a bed-plate arranged to slide within said space, and provided with a straight transverse projection corresponding to a section of rail, and a triangular transverse projection having one side parallel to the siding, and mechanism, substantially as specified, to actuate the said bed-plate.
2. The combination of the main track, the siding, the movable rails A B, the bed-plate arranged to slide in the space 0, and provided with the projections G and H, and switch mechanism, substantially as described, whereby the rails A B are simultaneously moved with the bed-plate, so as to open or close either the main track or siding, substantially as specified.
3. The combination of the main track, composed of the rails A A, the siding, composed z 5
