RAI LWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 487,538, dated De ember 6, 1892.

Application filed June 13, 1892. .Serial No. 436.543. (No model.)`

To all whom t may concern:

Be it known that I, WILLIAM RUSSELL Mc- GUIRE, of Fort Dodge, in the county of Webster and State of Iowa, have invented certain new and useful ImprovementsA in Railway- Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and highly-useful improvements in railwaygates or cattle-guards;l and it has for its object the production of cheap, simple, and highly-efficient mechanism whereby a gate or guard can be readily and easily operated or thrown open by a train moving in either direction, said gate or guard being automatically closed after the train has passed.

The invention comprises the detail construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan view of my improved railway gate. Fig. 2'is a transverse sectional view thereof on the line x Fig. l. Fig. 3 is a sectional view on the line y y, Fig. l.

Referring to the drawings, A A- designate the rails, and a at two corresponding operating-bars pivotally hung along the inner sides of said rails by means of crank-rods a2, eX- tended through holes in the vertical webs of the rails. These operating-bars normally occupy a position on a line with or slightly above the tread of the rails. To the inner end of each bar is secured a short bar a3, which forms an extension thereof and is provided with inner rack-teeth ct for engaging a pinion a4, whose shaft or stud is supported by a bracket a5, made fast to a tie or sleeper T. rPhe rackbar of the operating-bar a extends over this pinion, while the rack-bar of the operatingbar a is extended beneath said pinion, the teeth of both rack-bars always being in engagement with said pinion. Hence the movement of one operating-bar will effect the movement of the other bar in the opposite direction.

B B designate two sliding bars loosely held to the outside of each rail by nutted bolts b,

projecting from the rail-webs through slots b in said bars. To the outerends of these bars are connected rods b2, which at their outer ends are loosely connected to extended ends b3 of two of the crank-rods a2.

C designates the gate orguard, which is formed in two independent sections d d', each section being supported near its center and outer end byinner and outer rods d2 cl3, which are pivotally attached at their lower ends to tie T, so as to effect the backward and forward movement of each section. A spring dt, attached to each end of this tie and bearing against the end of the adjacent section, serves to hold the latter closed. To the out-er rod d3 of each gate-section are pivotally connected the inner ends of two divergent rods d5 d, which at their outer endsare attached to the sliding bars B B near the outer ends ot' the latter. From what has been said it will be seen that a train moving in either direction will upon striking against the pivoted operating-bars elfcct the lowering and forward movement thereof, the same turning the pivoted crank-rods, and by reason of the rackbar extensions the movement of the operating-bars on one side of the gate will effect the movement of those on the other side thereof. This movement of the pivoted operating-bars will cause the outer sliding bars B B to move forward toward each other and through the agency of the divergent rods d5 d6 cause the gate-sections to be thrown backward, withdrawing their inner ends from across the track, so as to permit the train to pass without striking thereagainst. As soon as the last wheels of the rear car of the train pass beyond the pivoted rods the gate-sections will be returned to their normal positions by the springs bearing against them.

The advantages of my invention are apparent to those skilled in the art to which it appertains, and it will be specially observed that a railway-gate or cattle-guard thus constructed is simple, inexpensive, and durable.

I claim as my inventionl. The herein-described improved railwaygate or cattleguard, comprising the gate formedin two sections capable of moving backward and forward, pivoted operating-bars extended along the sides of the rails on each side IOO side of said gate and having overlappingrackbars at their inner ends, the pinions between said rack-bars, the outer sliding bars operated by said former bars, and the divergentl rods connected to said sliding bars and also to said gate-sections,substantially as set forth.

3. The herein-described improved railway-y gate or cattleguard, comprising the gate formed in two sections and having inner and outer pivoted supporting-rods, the operatinghars extended along the inner sides of the rails, the pivoted crank-rods supporting said bars, the rack-bar and pinion connections between the inner ends of said operatingsbars, the outer sliding bars, the rods connected to the ends thereof and also to extended ends of said crank-rods, and the divergent rods pivotally connected to said outer sliding bars and also to the outer supporting-rods of said gate- 3o sections, substantially as set forth.

4. The herein-described improved railwaygate or cattle guard, comprising the gate formed in two sections having inner and outer pivoted supporting-rods, the springs bearing against the outer ends of said gate-sections, the crank-rods supported by the rails, the operating bars pivotally supported by said crankrods and having overlappin g rack-bars at their inner ends, the pinions located between said rack-bars, the outer sliding bars having slots, the nutted bolts projecting from the rails through said slots, the rods connected to the ends of said outer sliding bars and also to the extended endsof said crank-rods, and the divergent rods pivotally connected to said sliding-bars and also to said gate-sections, substantially as set forth.

In testimony whereof I have signed this specification in the Vpresence of two subscrib- 5o ing witnesses.

WILLIAM RUSSELL MCGUIRE.
