JULIus kEIsTEE, OE MAOON COUNTY, ILLINOIS.
-IMPRCWEMENT IN RAILWAY-GATES.
Specification forming part of Letters Patent No. 15114741, dated May 5, 1874; application filed February 23, 1874.
To all whom it may concern:
Be it known that I, JULIUs KE'IsTER, of Macon county, Illinois, have invented a Railway-Gate, of which the following is a specification:
My invention relates to an improvement in .railway-gates, designed chiey to take the place of cattle-guards. Its construction and operation can be better understood by reference to the accompanying drawing.
Figure l shows a broken section of my invention in perspective. Fig. 2 is an elevation of my invention on a vertical section of track. Fig. 3 is an elevation of a section of railwaytrack together with my invention.
A and B are rotating shafts, having their bearings in the perm anently-attached supports E E', and connected by chains F F. c and c are pawls attached to rails G C. b b are wheels having a ratchet or projection on one side, and are permanently attached to the shaft B. D is a guide for the rail C, showing' the spring cl in the broken section. t t are uprights of the gate. a and a are weights to bring the gate in position. The rail G is hinged or pivoted to the block c, which, in its turn, is attached to the Inain rail.
The gate is operated by the outside of the car-wheel pressing the rail C down, bringing the pawl c against 4the projection of the wheel b, forcing it around, thereby turning the shaft B, and indirectly, by means of chain F, the shaft A, bringing the uprights t t t toward the track and from the train. As the train strikes the rail C somel time before C', it turns the shaft B sufficient to get the projection on the wheel b out of the way bythe time C comes down. The operation is reversed by a train from an opposite direction. In this case the rail G' is first operated on, and pawl c misses the projection of wheel b.
The rail C, pawl c, ratchet b, support E, guide or guides D, spring d, and chain Fare arranged reversely on the opposite sides of the track, so that the down-train operates on one side and the up-train on the other side of the track, always turning the gate in the direction the train is going.
The rails G C are made long enough to reach from one set of wheels to another, and the pawls are guided by a bolt working in a slot, as shown in the drawing.
I claim as my inventionl. The combination of they rail C, spring d, guide D, and pawl c, as and for the purpose set forth.
2. The combination of the shafts A and B, supports E E', ratchet-wheel b, and chains F F', as and for the purpose set forth.
3. The combination, in a railway-gate, of shafts A B, rail C, pawl c, wheel b, support E, chain F, guide D, spring d, and uprights t t t, as and for the purpose set forth.
JULIUS KEISTER.
