SAND-BAND.

SPECIFICATION forming part of Letters Patent No. 425,252, dated April 8, 1890.

Application filed January 17, 1890. Serial No. 337,213. (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR L. PUTNAM, of Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain newand useful Improvements in Sand- Bands for Carriage-Axles, of which the following is a specification.

This invention has for its object to provide an improved sand band or collar to prevent the introduction of dirt between the inner end of the axle-box and the arm of the axle on which it rotates, and also to provide improved means for securing said band to the axle;

The invention consists in the improved devices which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a portion of a carriage-axle, said portion including the arm on which the axle-box rotates and my improved devices applied thereto. Fig. 2 represents a longitudinal section of the parts shown in Fig. 1, the wheel-hub being shown in dotted lines in the position it occupies on the axle relatively to the parts constituting my improvement. Figs. 3 and a represent perspective views, respectively, of the holder or attaching device and the sand-band.

The same letters of reference indicate the same parts in all the figures.

In the drawings, t; represents the axle-arm on which the hub j rotates, said arm being of the usual form and provided with the usual means for securing the hub thereto. The hub is also of the usual construction.

(t represents a collar, which on its exterior is nearly circular and has an angular opening 4: (shown in Fig. 3) of suitable size to receive the body 1' of the axle. that when it is placed upon the axle the body or square portion of the axle will fill the opening 4, and the circular periphery of the collar will then be concentric with the longitudinal center of the axle-arm i. The collar (t is provided at the lower portion of the opening 4 with an arm or plate 2, which is arranged to bear upon the under side of the axle 'i', and to be held in place on the axle by the cross. bar I; of the usual clip c, which connects the Said collar is so formedinetallic body t of the axle to the wooden section '2', said clip serving, therefore, not only to secure the ironand wooden sections '2' and t'" together, but also to secure the collar on to the axle. On the periphery of the collar (1. are two segmental ribs a a',the purpose of which will be hereinafter explained. I

cl represents the sand band, which is a circular collar formed internally to fit closely upon the periphery of the collar a, and having on its outer surface a flange d of considerably larger diameter than the collar ot, said flange d projecting outwardly from the collar a, as shown clearly in Fig. 2. The sand-band a is provided with a series of rearwardly-proj ecting ears 9 which are provided with screwthreaded holes to receive projecting ears, and the screws g, that attach the sand-band to the collar a, said collar having screw-threaded holes g to receive said screws. the segmental ribs, above referred to, are arranged to act as guides for the ears g, so that the operator can without difficulty apply the sand-band to the collar a when the screwholes in the sand-band coincide with those in the collar.

The flange (Z' of the sand-band is provided with a recess 71:, (shown in Fig. 4,) at one side of which the said flange is enlarged or extended outwardly to form a tooth m, said tooth being adapted to cut a groove 0 in the inner end of the wooden hub 3', when said hub is placed upon the axle-arm, and at the same time rotated and pressed inwardly, the sandband being thus enabled to form a seat or groove for itself in the inner end of the hub. The cuttings formed by the action of the tooth are enabled to escape by the recess 7.3.

It will be seen that the circular collar a, adapted to be detachably secured to the axle andpresenting a seat or supporting-surface which is concentric with the arm of the axle, enables the sandband to be readily applied to any of the common forms of carriage-axles Without any adaptation of the axle to receive the sand-band, it being only necessary to insert the arm or plate 2 of the collar. a between the bottom of the axle and the cross-bar of the clip 0, and then attach the sand-band to the said collar.

I claim-- The ends of 1. The collar a, adapted to be detachably secured to a carriage-axle and provided with an angular opening 4, and a circular periphery having segmental ribs a and screw-holes g", combined with the circular sand-band formed to fit upon said periphery, and provided with ears g, having screw-holes adapted to coincide with the screw-holes of the collar a, said ears being guided by the ribs a, as set forth.

2. The combination,with the collar a, hav

ing the axle-receiving opening 4, and a circular periphery which is concentric with the axle-arm when said collar is in place on the axle, combined with the sand-band adapted to be detachably secured to said collar, and
