Improvements in Metallic Hubs and Axles.
I, ZACHARY THOMAS WILSON of Inverness Citrus County Florida United
States of America Carriage Maker do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to metallic hubs and axles for vehicles, and its object is to
provide an improved construction of the same which shall effectively prevent the
entrance of dirt or dust between the axle spindle and hub, and which will otherwise
possess superior advantages with respect to efficiency in use.
The invention consists in the novel construction and combination of parts
hereinafter fully described and claimed.
In the accompanying drawing:
Figure 1 is a side elevation of a metallic vehicle hub constructed in accordance
with my invention ;
Figure 2 is a central longitudinal section of the same;
Figure 3 is a central longitudinal sectional view of the spindle detached from
the hub;
Figure 4 is a similar view of the nut which fits on the inner ends of the hubs.
In the said drawing, the numeral 1 designates a metal hub comprising an axle
box and spoke seat 2 formed integral therewith, which spoke seat is formed with a
number of equi-distant peripheral sockets 3 to receive the spokes, and formed with
the usual tapering bore 4, for the insertion of the spindle. The outer end of the
axle-box is made solid or without any opening therein, so that it is impossible for
dirt or dust to enter the axle box from this side. The bore 4, near its center, is
formed with an annular groove 5, which constitutes a receptacle for containing oil
or other lubricating material.
The numeral 6 designates an axle formed with a tapering spindle 7, and an
annular collar 8, at the junction of the axle and spindle. On its inner face the
collar 8 is formed with an annular flange 9, adapted to engage with an annular
groove 10, in the inner end of the hub, concentric with the axis thereof.
The inner end of the hub is formed with a number of circumferential screw-
threads, with which engages a correspondingly threaded nut 12, having a central
opening with which engages the cylindrical portion 13, of the axle.
The operation is as follows: The spindle is inserted in the bore of the hub, the
flange 9 seating in the groove 10 and the collar 8 abutting against the end of the
spindle. The nut 12 is then screwed on the inner end of the hub bolding it securely
on the spindle, yet permitting it to rotate freely thereon.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination with the metal hub having a solid outer end a circum*
ferentially screw-threaded inner end and a tapering bore, of the spindle having an
annular collar formed with an annular flange, and the nut having a central opening,
enhstantially as and for the purpose specified.

page_text: 2. As an improved article, the herein described metal hub having a central
tapering bore formed with an annular groove intermediate its ends forming an oil
receptacle, and having its outer end made solid, substantially as herein shown and
-specified.
Dated this 18th day of May 1894.
