'OLOF P. JOHNSON, OF NEW YORK, N. Y.

COW-CATCHER FOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 253,208, dated February 7, 1882.

Application filed October 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, OLOF PETER JOHNSON, of New York, in the county and State of New York, have invented an Improved Cow-Catcher for Locomotives, of which the following is a specification.

The object of my invention is to provide an improved device to be applied to the so-called cow-catcher or buffalo-plow of a locomotive for more effectually removing from the track minor obstacles which might otherwise get'between the rails an d the wheels, and cause serious accidents by throwing the locomotive off the track.

In the accompanying drawings, Figurel represents a top or plan view ofmy improved cowcatcher. Fig. 2 is a longitudinal section of the same, taken through the line or or ofFig. 1. Fig. 3 is a detail end view, in the direction of the arrow, seen from the section-line 3 y of Fig. 1. Fig. 4 shows a modification.

Like letters of reference indicate like parts in the several figures.

A designates the fore part of a locomotiveframe or of the front truck of a locomotive, to which the improvement may be attached.

B is a strong iron frame or bracket for securing the cow-catcher to the frame A.

G is the central rib of the cow-catcher, and is rounded off and widened at the point, as shown in Fig. 1, to form a bearing on each side at c, for receiving one end of a horizontal shaft,

D, whose other end is mounted in a bearing, a, upon the lower outer end of a downward and outward projecting portion b, of the iron frame B. The shafts D form about the same angle with each other as do the two lowest opposite ribs of the ordinary cow-catcher, and are pro- I vided longitudinally with radially-projecting vanes d, preferably four in number, and a cogwheel, E, whose outside radius should not exceed that of the vanes (I.

In the lower end of the frame portion 1), and in a bracket, F, projecting rearward a little from the under side of the plow-poin t, are laterally opposite respective bearings 6 eff, in which are mounted shafts G.

Upon each of the shafts G are secured cogwheels H l, the wheel H gearing with the wheel E upon the shaft D, and the wheel I gearing with a cog-wheel, J, upon a shaft, K,

which is mounted in the frame A, parallel with the driving-axle of the locomotive, from which axle it receives its motion through belt and pulley M L or other suitable means of transmission. If the wheel I, gearing into the wheel J, were fixed on the rear end of the shaft D, as in track-clearers heretofore constructed, (see Patent No. 38,622,) the angle between the two shafts D would necessarily be more acute with the same length of vanes, and the rear end of the cow catcher narrower than the frame; but by the intervention of the shafts G and their cog-wheels H, gearinginto wheels E upon the shaft D, as described, the cowcatcher may be made of any width or obtuseness of angle desired without extending the axle K beyond the frame A-that is to say, the width of the rear end of the catcher may be made greater than the width of the locomotive-frame, as shown in Fig. l, regardless of the length of the axle K. If A-be the forward truck-frame, K should be the forward truckaxle, from which, in that case, motion is taken to the shafts G director without an intermediate shaft. The shafts D, with vanes d on them, being thus revolved by power from the locomotive-wheels, will of course turn more or less rapidly, according to the proportion in size of gear-wheels and to the speed of the locomotive. Any minor obstacle struck by the cow-catcher during the progress of the locomotive will be caught by the rapidly-revolving vanes d and thrown off from the track in the direction of the tangent of revolution of the vanes. If the shafts D be placed at an angle of ninety degrees and the vanes on one shaft be extended to the circumference of the vanes of the other, as shown-in Fig. 4, the point of the cow-catcher may be formed by the ends of the thus extended vanes, the latter of course in that case being cut away down to the shafts D, at a distance from their front ends, preferably at the side of the cog-wheels E, to expose a small portion of the shafts, just sufficient for mounting them in bearings projecting from the bracket F.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the axle or shaft K, having cog-wheels J, and the converging shafts D, provided longitudinally with radial vanes d, and having cog-wheels E, not exceeding in diameter the side vanes, with the intermediate shaft G, provided with cog-wheels I H, gearing into the said wheels J E, all constructed and operating as and for the purposes shown and described.

2. The combination of the two shafts D, provided longitudinally with radial vanes (I, when a arranged as in Fig. 4, the vanes of one shaft 10 extending to the outer circumference of the vanes of the other and forming the point of the catcher.
