SPINDLE-BUSHING- Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed September 30, 1902. Serial lilo 125,412.

T0 all whom it may concern:

Be it known that we, J ESSIE J. HINES and ELDRED B. WILKERSON, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented a new and useful Spindle-Bushing, of which the following is a specification.

This invention relates to the spindles of the axles and the hubs of the wheels of vehicles, and has for its object the ready repair of worn axle-spindles and hub-sleeves, whereby the worn spindles and sleeves may be restored at a small expense, thus saving the axles and wheels when the spindles and sleeves are Worn; and the invention consists in incasing the worn spindle with a shell conforming exteriorly to the original spindle and securing it in place relative to the worn spindle by a metallic com pound inserted into the space between the spindle and shell.

In the drawings illustrative of the method employed in applying the invention, Figure 1 represents a side elevation of a worn axlespindle with the improvement applied, the improved portions being in longitudinal section. Fig. 2 is a longitudinal section of a hub with the restored sleeve in place therein. Fig. 3 is a side view of a worn spindle of an axle. Fig. 4 is a longitudinal sectional elevation of a hub having a Worn sleeve therein.

Fig. 5 is a transverse section on the line V V' of Fig. 1.

When axle-spindles become badly worn and past repair, they are generally cut from the axle and replaced by new spindles,-but this entails heavy expense and necessitates the removal of the axle from the vehicle, which action disfigures the vehicle and necessitates the repainting of part, if not all, of the vehicle.

WVith the improved device worn spindles may be very quickly and readily restored without removing the axles from the vehicle or disfiguring it in any manner.

For the purpose of illustration a worn spindle 10 is shown in Figs. 1 and 3 with the usual sand-collar 11, having an annular groove 11 and the threaded end 12 for the holding-nut, the latter not being shown, as it forms no part of the present invention.

The improvement consists in a metal shell 13, conforming exteriorlyto the original spindle and placed over the worn spindle l0 and poised thereon in any suitable manner, so that the worn spindle is centrally disposed thereon or whereby the shell 13 occupies the place with reference to the axlea short section of which is represented at 14formerly occupied by the spindle 10 before it became worn. A readily-fusible metallic compound in a molten state is then introduced into the space between the shell 13 and the worn spindle to form abinding means to support the shell in place. By this simple means the spindle may be very quickly and readily restored and made as good as new without removing the axle from the vehicle or disfiguring the vehicle in any manner.

The shell 13 will preferably be provided with apertures (indicated at 15) at suitable intervals and forming means for the introducti 3n of the metallic compound, (indicated at 16.

The metallic compound will preferably be Babbitt metal or similar material or compound which will melt at a low temperature; but any metallic compound may be employed for this purpose, and we do not, therefore, wish to be limited to any particular com pound or material for the binding means as above noted. The repairing-shell 13 maythus be very quickly and readily secured in place, and will be immovable thereon, as the compound filling 16 will become attached immovably to both the shell and the spindle by engaging the apertures 15 in the shell and the annular groove 11' in the collar 11 of the spindle, thus firmly binding them together. Said filling will obviously also fill the wear-cavities in the spindle, and thus assist in binding the parts together.

The molten compound will readily adapt itself to all of the irregularities of the surface of the spindle 10, and thus support the shell 13 exactly concentric to the spindle and occupy the exact location of the original unworn spindle. This makes a very eflicient and easily-applied device whereby old axles may be restored and rendered as good as new, and may be applied by any wagon-maker or blacksmith'or even by those not skilled in the art.

The hubis represented at 17 of the ordinary construction and provided with the usual hubsleeve 18, conforming interiorly to the exterior of the shell 13.

It is a common expedient to remove the worn sleeves and replace them with new sleeves, and in operating the improved method of repairing axles this will be done as the shell 13, conforming to the original axle-spindle, will of course fit the new sleeve 18 inserted into the hub 17, thereby completely restoring the worn parts.

The shell 13 may be provided with the usual oil ducts or cavities; but as these form no part of the present invention they are not illustrated.

The shell 13 will preferably be formed of hardened steel and will be of sufficient thickness to withstand the strains to which it will be subjected and to resist the pressure of the wheel skein or sleeve. The shell 13 thus forms a bushing between the worn axle-spindle and the sleeve of the hub which receives all the wear and when worn can be readily replaced by a new one.

It is obvious that the invention could likewise be employed as a bushing in connection with unworn or new axle-spindles to serve as a wearingesurface and prevent wear upon the spindle, and when the bushing becomes worn the axle could be renewed in the same manner as above noted.

Having thus described the invention, what is claimed is The combination with an axle having a spindle and a sand-collar, the latter provided with an annular groove, of a device presenting a new wear-surface when the spindle has become worn; the same consisting of a sleeve of wear-resisting material fitted upon the spindle concentric with the axis thereof and having a portion extending over the sand-collar; said sleeve being provided with a plurality of perforations; and a filling of readilyfusible material introduced into the'space between the spindle and the wearresisting sleeve through the openings in the latter; said filling occupying the said intervening space, the annular groove in the sand-collar, and the perforations in the wear-resisting sleeve.

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in the presence of two witnesses.
