\VILI.IAM NEHRING, OF EVANSVILLE, INDIANA.

WAGON-AX LE.

SPECIFICATION forming part of Letters Yatent No. 465,625, dated December 22, 1891.

Application tiled March 23, 1891. Serial No. 386,097. (No model.)

To @ZZ whom t may concern.-

Beit known that LWILLIAM NEHR1NG,a citizen of the United States, residing at Evansville, in the county ot' Vanderburg and State of Indiana, have invented certain new and useful Improvements in VVagon-Axles, ot' which the following specification, taken in connection with the accompanying drawings, is a full, clear, and exact description, such as will enable those skilled in the art to which they appertain to make and use the same.

My invention relates to improvements in that class of wagon-axles in which detachable hollow axle-spindles are employed; and the object of my Vinvention is to provide an axle which will be simple in construction and at the same time strong, durable, and effective.

My invention consists, principally, of three features of novelty: first, an improved axle composed of a wooden core and strengthening-strips of metal; second, a detachable hollow spindleprovided with a detachable wearstrip of peculiar construction, and, third, an improved arrangement for utilizing the hollow spindle foraiubricating-chamber and my invention consists of other features of novelty, all of which will be first described with reference to the accompanying drawings, and then more particularly pointed out in the claims.`

Fig. VII is a sectional view taken on line VII VII of Fig. II. Fig. VIII is a side elevationof my improved clip. Fig. IX is a sectional view of my improved spindle having a slightlymodified form of wear-strip. Fig. X is a similar sectional view showing the same form of wear-strip without the perforation for the passage of oil.

Like letters of reference indicate the same parts throughout the several views.

Arepresents the axle, B the hollow spindles, and C the securing-clips. The axle A is constructed to receive my improved form of spindle, as will presently appear.

The spindle B is formed with the bearing portion b forithe reception of the wheel and the socket portion Z9 for fitting over the end of the axle. The socket h has a shoulder b2, against vwhich a similar shoulder on the axle abuts. b3 is a convex groove formed on the under side of the spindle B and adapted to receive a convex wear-strip D. The strip D is confined from longitudinal movement between the socket portion o and a shoulder b4 at the outer end of the groove hsl E is a collar` adapted to iit on the spindle and hold the inner end of the wear-strip snugly against the spindle. e is a lug formed on the upper surface of the spindle B and adapted to engage in a notch e', formed in the inner edge of the collar E, to prevent its turning. The spindle has the custo mary screw-threaded nib h5 at its outer end for the reception of the wheel-retaining nut F, which nut is formed with an annular collar f, which engages the outer end of the wear-strip D for holding it against the spindle.

G are washers iittin g on the spindle against the collars E and f and provided with lugs g, which engage in notches in said collars, whereby they are prevented from turning, so that they can take up all the wear on their bearing-faces.

The hollow or cavity D of the spindle B is utilized for an oil-reservoir, the oil being conned in the outer half of the cavity by shoulders or dams bi.

l1 is an oblong perforation or slit in the bottom Wall of the reservoir b, which registers with a similar slit d in the center of the Wearstrip D. The outer or bearing surface of this wear-strip D is provided with oil-distributing grooves d', leading from the ends ot' the slit @whereby oil passing from the reservoir h6 is fed Vto the wheel-bearing. The nibl/5 is perforated longitudinally, and the nut F is also perforated and provided Witha suitable cover or door fwhereby the nowilmay be readily inserted intothe-reservdir; or, if preferred, the nut F may be formed whole without the persuitable perforations.

foration,wlien it will be necessary to remove it from the axle when it is desired to insert the oil into the hollow spindle.

The axle A is formed of a central strip or core a of wood and two outer inclosing strips or thin bars a of tempered' iron or steel, the parts being securely riveted or bolted together by means of rivets or bolts a2, passing through The ends of the axle are formed with shoulders a3, which, when the spindles B are put in place, abut against the shoulders b2 and the edge of the upper surface of the spindle-sockets, whereby when the clip C and the bolts or rivets are put in place a secure joint is formed between the axle and detachable spindles and a stout and economical axle formed. It is obvious that the axle and spindles are perforated at the proper places for the reception of the bolts and the central bolt of the clip C.

. The clip C is provided with the customary screw-threaded bolts or arms c, the keeper c', perforated to tit over these bolts, and nuts c2 to retain the keeper in place. In addition to this, in my improved clip I provide a central perforation in the keeper and one in the arch of the clip, through which a central bolt c3 passes and holds the clip securely in position. This form of clip is of particular advantage in combination with my improved wagon-axle, as it makes it impossible for the clip to slip longitudinally out of place.

In Figs. IX andX I have shown a modified form of wear-strip applied to my improved axle-spindle. In this form the small or outer end of the concave wear-strip D is 'provided with a retaining-hook cl2, adapted to engage in a perforation cl3 in the under side of the spindle B, which assists in holding the wearstrip to the spindle. The collar E and retaining-nut F are also employed in combination with this form, the principal function of the hook cl2V being to retain that end of the wearstrip in position when the nut and'wheel are removed. L L are perforated ears or lugs formed on the enlarged end of the detachable spindle, through which thearms of the clip C may pass.

Figs. IX and X differ only in the omission of the central lubricating-chamber from Fig. X, in place of which the lubricant may be supplied as is now commonly done.

The hollow spindle may be formed of a metal casting o r of a solid forged piece of metal, with the oil-chamber bored in. The wear-strip is formed of any suitable metal which is softer than the journal-box of the wheel, so that the wear is taken up entirely by said strip and the spindle and wheel are protected.

Having thus fully described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. An axle-spindle having aconcave groove in its surface, in combination with a concave wear-strip adapted to fit in said groove, and

suitable collars fitting on the spindle and enon the spindle, whereby the collar is prevented froln turning, substantiallyas set forth.

Ll. The combination of an axle-spindle with a wear-strip set in its surface, said wear-strip being formed of softer m etal. than the spindle, whereby it takes up the wear and'protects the spindle and journal-box of the wheel, as herein set forth.

5. `The combination of a hollow axle-spindle, a wear-strip, means for connecting the wear-strip to the spindle, and a perforation through the spindle and strip, substantially as set forth.

6. The combination of a hollow axle-spindle, an oil-inlet, shoulders or dams formed in said hollow spindle for conning the oil, and an oil-outlet, as herein set forth.

7. The combination of a hollow axle-spindle, dams formed in said spindle for confining the oil, an oil-outlet, an internally-screw threaded retaining-nut adapted to engage the end of said spindle, and an oil-inlet door in said nut, whereby the oil can be placed in said spindle behind the outer dam, as herein set forth.

8. An axle-spindle formed with agroove on its surface, a wear-strip iittin g in said groove, a hook formed on one end of the wear-strip and adapted to engage in a perforation in the spindle, and a collar adapted to engage the other end of the wear-strip, substantially as set forth.

9. The combination of an axle-spindle, a socket-piece formed thereon, perforated lugs or ears L, the axle A, and a clip, substantially as set forth.
