ROBERT A. BROOK, OF SPRINGFIELD, OHIO.
STREET-CAR SWITCH-OPERATING MECHANISM.
SPECIFICATION forming part of Letters Patent K0. 721,279, dated February 24, 1903. Application filed November 1,1902. S erial lNo. 129,764. (No model.)
To all whom it may concern:
Be it known that I, ROBERT A. B30015, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Street-Oar Switch-Operating Mechanism; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled parts, as will be hereinafter more fully described and then specifically defined in the appended claim. V 7
My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings' Figure 1 is a vertical sectional view through my improved mechanism. for operating switches. Fig. 2 is abottomplan view of a car, showing the membersfor trippingthe switch mechanism; and Fig. 3 is a sectional view transversely across the tracks, showing the manner in which the switch is operated as one of the members secured to the car is brought into contact with the tripping mechanism.
Reference now being had to the details of the drawings by letter, A A designate the tracks of a railway, and B a switch-rail. Mounted between cross pieces Ointermediate the rails is a standard D, on which is mounted a tilting bar E, having a downwardly-extending portion E, to'which one end of a rod" F is connected, the other enduof which rod is fastened to the swinging switchrail B. Near each end of said tilting bar is journaled an antifriction-roller H, the outer end of each being preferably flanged in order to hold the tripping member upon one or the other of said rollers, accordingly as it is desired to open or close the switch.
Mounted upon the bottom of the platform of a car is a shaft K, to which are loosely held corresponding ends of the bars L and L. These bars, which may be of any desired shape or formed, if preferred, into the shape of rods, extend underneath the car and are normally held with their free ends against the bottom of the car by means of the pushpost-s N, which are connected to said bars in any suitable manner. A spring is mounted on each push-rod and bears between the head of the rod and the plate M, fastened to the under surface'of the car. By means of said springs it will be observed that the free ends of said bars will be normally held in contact with the under surface of the bottom of a car. Said bars are spaced apart and are adapted when depressed to be in positions to contact with one or the other of said antifriction-rollers upon the tilting bar, which actuates the switch to open or close the same,
:as may bedesired.
- M hile I have shown a certain detailed construction embodying the features of my invention, it will be understood that I may make alterations in the details of the device without departing from the spirit of the invention.
Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is I V The combination in a switch operating mechanism, of a'tiiting bar mounted between the rails of a railway, flanged antifrictionrollers mounted on said bar, and means for throwing the switch-rail as said bar is tilted,
a shaft mounted on the under surface of a pressed by the push-rods so as to contact with said antifrictionrollers, as. set forth.
In testimony whereof I hereunto affix my signature in presence of, two witnesses,
ROBERT A. BROOK.
