UNITED STATES PATENT Ormes;

CHARLES COOK, OF VVINSTED, CONNECTICUT.

SPECIFICATION forming part of Letters Patent No. 254,466, dated March 7, 1882. Application led- November 12, 1881. (No model.)

To all whom t may concer-n:

Be it known that I, CHARLES 000K, of Winsted, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Axles; and I do hereby declare that the following is a full, clear, and exact description thereof', whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon. A

Like letters in the figures indicate the same parts.

My improvementrelates to carriage or wa gon axles,`and its object is to provide a more efflcient mechanism for keeping the sand out of the rear end of the axle-box than has heretofore'been in use.

In the accompanying drawings, illustrating my invention, Figure l shows a cross-section through the axle-box, with the axle represented in full within it. Fig. 2 shows a cross-section through Fig. l on the line A represents the axle.

B is the axle-box.

C is the nut for holding on the wheel.

D is the flange at the rear of the spindle of the axle for receiving the inward thrustofthe wheel. Back of this there has heretofore been in use a second flange, with an intervening space or groove to form a sand-box, which has been covered by the rear end of the axle-box, so as to form an inclosed space. Upon this construction my present invention is an improvement.

E is the rear flange of the axle, comingnearly or quite ush with the rear end of the axle-box B, and forming part of that portion of theaxle back of the spindle. Its outer circumference is intended to fit as closely into the axle-box as possible without touching, so as to prevent the entrance of sand and dirt as far as practicable.

Between D and E there has heretofore been a single groove. In my improved axle I insert another flange, F, so as to divide the space into two parts. The outer groove, Gr, serves as the sand-box proper,iu which the sand collects in the customary manner, and is cleaned out whenever the wheel is taken off for oiling, and the inner groove, H, serves more particularly as a-receptacle for the oil and axle-grease, and presents a more effectual bar to the entrance of sand to the wearing part of the axle. The amount of oil or grease which escapes around the edge of the flange Fagglutinates and holds the sand in that channel, yso that very little passes through into the groove H, and what little may pass over is held there by the grease and does not reach the axle-bearing.

By means of my improvement the sand and dust that have heretofore found their way past the flange D are entirely excluded.

What I claim as my invention is- The iiange F, in combination with the axle provided with the ilangesD and E, and the axlebox B, closely surrounding said Hanges, whereby the two inclosed grooves or channels G H are formed, substantially as described.

CHARLES COOK.
