IMPROVEMENT IN RAILWAY-GATES.
Specification forming part of Letters Patent No. 222.6311., dated December 16, 1879; application filed October 31, 1879.
To all whom 'it may concern:
Be it known that 1, HENRY D. KAHLER, of Mount Auburn, in the county of Benton and State of Iowa, have invented a new and valuable Improvement in Railway-Gates and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of -this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a representation of a crosssectional view of my improved railway-gate. Fig. 2 is a longitudinal section of the same; and Figs. 3, 4, and 5 are details.
This invention has relation to improvements in automatic railroad-gates; and the nature of the invention consists in the combination, with a tilting track-frame arranged at each side of a track at right angles thereto, of gatesmovin g endwise in said frames and designed. to run across the track or away therefrom, and a mechanism actuated to tilt said frame by the contact of the wheels of the car.
It also consists in certain minor improvements whereby desirable results are obtained, as will be hereinafter more fully set forth.
In' the annexed drawings, the letters A A indicate the rails of the track, laid upon ties in the usual way. B indicates sills arranged one at each side of the track, parallel thereto, l
and affording bearings to the vertically vibrating or tilting frames (l. rlhese are composed ofthe sills a and two or more vertically-slotted uprights, Z1, suitably braced. These frames are at right angles to the track, and are provided each with journal-arms c, that have their bearings on the ground-sills and readily 1 tilt thereon. The sills a of these frames are provided with arail, a', upon which runs a gate, A', of openwork construction, so as not to hold the wind, the upper rail of which is horizontal and runs between the antifrietion When these' frames are tilted on their bearings so that their ends adjacent to the rails are lowest, the gates run down the incline until they come together at the middle of the track and form a complete barrier acrossl it;
but' when they are tilted in the opposite direction the gates move away from each other s. In coming together, also, the gates are stopped by a shoe, c', between the rails, in which the lower ends of said gates are re ceived, and by means of which they are prevented from injurious contact. Extending across the track, at suitable distances apart, and on each side of the gate, are the rockshafts D D', carrying each a downwardly-pro jecting arm, e, and having applied on their projecting ends, outside of therails, the curved tread-levers D2 D3, the former being on the shafts D, and the latter on the shafts D. Between the rock-shafts DD, on one side of the gate, is a rOckshaft, E, providedinside of the rails with the angular levers c', one arm of which is vertical, and the other or lower arm horizontal. The extremities of the horizontal arms of these levers are connected `by a link, j', to the vertically-vibrating levers E', having their fulcrums in an upright, j",'under the track, and extending under the tilting trackframes aforesaid.
g indicates metallic rods extending from the bend of levers e to the arm c of rock-shaft D,
and forming tlexible joints both with the lei vers and with the arms.
It is evident that the depression ofthe levers D2 of shafts D on this side of the gates will, through the arms e, rods g, arms e', links f, and levers E', raise the ends of the'tilting frames next the track and cause the gates to open. The
props h are forced under the frames by the,
springs i and hold them until the train has passed. These props are connected to a horizontallyarrangcd cross-head, J, by means of the rods i', connected pivotally at one end to the props, and at the other to the ends ofthe horizontally arranged and vibrating crosshead aforesaid. Above the cross-head is a rock-shaft, G, having at each end, inside of the rails, the fixed 'cross-heads 7c, extending up equally above and below it. Between the heads 7c is a downward-projectin g arm, o, flexibly coupled to an offset, l, projecting at right angles from the head. The lower ends of the heads 7s are connected by the rods a to the arms c of the shaftsD' on one side of the gate, and the upper ends thereof to the corresponding arms e oi' the shafts D' on the other side of said gates; so when either of the treads D3 is depressed the props are withdrawn from under the tilting frames, when the latter, being heavier at their ends adjacent to the track, tilt downward, and the gates run toward each other, closing the track automatically. Like the levers D2, the levers D3 are raised and depressed simultaneously.
What I claim as new, and desire to secure by Letters Patent, is-
l. The combination, with the track AA, the tilting frames C, arranged at the sides oi' the track, and the traveling gates A', mounted in said frames, of the vertically-vibrating levers E', extending under the frames, the links f, the rockshaft E, the levers e', the connecting-rods g, the rockshafts DD, having arms e, and the tread-levers D2 on the ends of said shafts, substantially as specified.
2. The combination, with the tilting' frames C and the sliding gates A', of the vibrating props h, the springs i', the horizontally-vibrating cross-head J, the rods il', connecting the props and ends of said head, the rock-shaft G, having the arm o, pivoted to the cross-head, the arms lc, the rock-shafts D', having the arms e, the rods n, connecting said arms c and It', and the tread-levers D3 on the ends of said shafts, substantially as specified.
3. The combination, with the tilting frames C C and the gates A', sliding endwise therein, of the stops D4 and springs s at the outer ends ofsaid frames, and the stop-shoe o between the rails, substantially as specified.
4. The combination, with a track, the tilting frame at each aside thereof, and the gates moving endwise in said frames, of the vertically-vibrating levers E', extending under the frames, the links f, the angular levers e' on sha-ft E, the rock-shafts D D', having crankarms e, and rock-shaftfG, having cross-heads 7c, the connecting-rods g, g', and n, the latter uniting the upper and lower ends of the crossheads of the shaft G and the said crank-arms e of shafts D' and the tread-levers D3 D3, sub stant-ially as specified.
In testimony that I claim the above I have hereunto subscribed my name in the presence ot' two witnesses.
HENRY D. KA H LER.
