REVOLVING GUARD FOR LOCOMOTIVE COW-CATCt-LERS.

SPECIFICATION forming part of Letters Patent No. 288,788, dated November 20, 1883.

Application filed February 5, 1883. No model.)

1'0 all whom, it may concern:

Be it known that I, J our D. FISK, of Hartford, in the county of Hartford and State of Connecticut, have invented new and Improved Revolving Guards for Locomotive Cow-Catchers, of which the following is a full, clear, and exact description.

The object of my invention is to provide new and improved revolving guards for locomotive cow-catchers, to throw snow, stones, ties, or other obstructions from the track.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure'l is a plan view of a cow-catcher provided with the revolving guards, the cowcatcher being shown in dotted lines, and the prongs being omitted from the guard-shafts. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is an enlarged longitudinal view of part of the revolving guard. Fig. 4 is a crosssectional elevation of the same. Fig. 5 is a front view of a modification, and Fig. 6 is a side view of another modification.

A shaft, A, is journaled in jaws a, projecting from the front side of each bottom rail, B, of a cow-catcher, G, in such a manner that the said shafts will be parallel with the said bottom rails. The shafts A are provided on the adjoining ends with cog-wheels D engaging with beveled cog -wheels E, made integral with or attached to the sides of a small sprocket-wheel, F, journaledin the front lower part of the cowratcher. A drivingchaiu, G, passes over a sprocket-wheel, H, on the front axle, J, of the locomotive. On the shafts A a series of collars, K, are mounted and held on the same by screws L or other suitable devices, which collars are provided with opposite blades M, about three inches long from the center of the shaft, and about two inches wide. The collars are so arranged that the ends of the blades form spiral lines, and so that the blades will be about two inches apart. The ends of the blades project about two inches below the bottom rails of the cow-catcher.

When the locomotive is in motion, the sprocket-wheel H on the front axle operates chain G, which in turn operates the sprocketwheel F, from which the motion is transmit ted to the shafts A, the same being revolved in the direction upward and toward the cowcatcher, so that their blades M will throw objects against which they strike from the catcher. The revolving guards formed by the shafts A and blades M will throw snow from three to eight or nine inches deep, or stones, ties placed on the track, and other like obstacles, from the track, so that the said obstacles can under no circumstances pass under the cow-catcher, and are thus prevented from throwing the locomotive from the rails.

If desired, the blades or wings M can be made tapering and curved, as shown in Fig. 5, or they can be twisted like the blades of a screw-propeller, as shown in Fig. 6, or be arranged parallel with the shafts. In fact, the blades may be of any suitable length and width, and be arranged radially close together or more or less apart on the shafts, at any angle therewith, or with their ends describing a spiral line, as above described.

In place of an angular cow-catcher,a straight cow-cateher can be used. A single spiked or pronged shaft is then journaled on the same, which shaft is provided with a central single cog-wheel, which is operated by the. cogwheel E.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A cow-catcher having the shafts A A journaled in the jaws a, provided with bladed collars K, and projecting from the front side of and parallel with each bottom rail, B, in

combination with the bevel cog-wheels D E, thesprocket-wheels F H, the chain G, and

the axle J, as and for the purpose described.

2. The blades mounted upon the shafts A by collars K, and having their ends arranged in spiral lines, as and for the purpose specifled.

3. The combination, with a locomotive cow catcher, of the shafts A, journaled in front of the lower part of the same, devices for rotating the said shafts from an axle of the locomotive, and of collars K, provided withblades or wings M, and mounted on the shafts A, substantially as herein shown and described, and for the purpose set forth.

* 4. The combination, with a locomotive COW-021361161, of the shafts A, journaled in around the shafts, substantially herein front of the lower part of the same, devices shownand described, and for the purpose set for rotating the said shafts from an axle of forth.

the locomotive, and of collars'K, provided JOHN D. FISK. [LS1 5 with blades or Wings M, which collars are \Vitnesses:

mounted on the shafts in such a manner that MAHLON R. WEST,

the outer ends of the blades form spiral lines JOHN XV. OOOGAN.
