THOMAS PAXTON, OF EL PASO, TEXAS.
LATERAL-WEAR REDUCER FOR LOCOMOTIVES.Specification of Letters Patent.
Patented Mar. 29, 1921.
Application filed September 24, 1919. Serial No. 325,904.
To all whom it may concern:
Be it known that I THOMAS PAXTON, a
citizen of the United States, residing at El
Paso, in the county of El Paso and State
5 of Texas, have invented certain new and
useful Improvements in Lateral-Wear Re-
ducers for Locomotives, of which the fol-
lowing is a specification.
This invention relates to means for pre-
10 venting or reducing lateral wear on loco-
motive driving wheels and it has for one of
its primary objects the reduction of the lat-
eral wear to a minimum thereby greatly re-
ducing the expense and the losses incident
15. to the withdrawal of the locomotive out of
service to drop out the driving wheels and
take up the lateral wear. In this connec-
tion, it is not at all uncommon to drop out
the driving wheels one or more times be-
20 tween general shoppings of the locomotive
to take up the lateral wear and those fa-
miliar with this art will readily understand
what is involved in such practice.
The foregoing, together with such other
25 objects as may hereinafter appear, I obtain
by means of a construction which I have
illustrated in preferred form in the accom-
panying drawings, wherein-
Figure 1 is a cross section through a loco.-
30 motive driver and a driving box, illustrat-
ing the application of my invention; and
Fig. 2 is a side elevation of a floating hub
liner I employ in carrying out my inven-
tion.
35 Referring now to the drawing, the refer-
ence letter A indicates a driving axle, jour-
naled in the driving box B, and the refer-
ence letter C indicates a driving wheel. The
driving box B, which may be of any pre-
40 ferred standard type, is provided with the
usual brass 7 and may, ormay not be pro-
vided with a liner 8, as desired. In the in-
ner face of the hub 9 of the driving wheels,
I provide an annular recess 10 adapted to
45 receive a floating hub liner or ring-like
member 11, such liner being provided with
a plurality of suitably spaced apertures 12
extending therethrough and preferably en-
larged or reamed out on the hub face of the
50 liner as shown. A duct 13 is formed in the
hub of the driving wheel, the inner end of
which is located the same distance from the
center of the axle as the apertures 12. The
outer end of the duct 13 is threaded to re-ceive the neck of a grease or other lubricat- 55
ing cup 14, which is preferably of the com-
pression type.
The liner 11 is preferably made of steel,
finished on all sides, and it fits the recess 10
sufficiently loosely to float as the driving 60
wheel revolves, that is to say, it revolves at
a much slower,speed than the wheel for the
reason that it bears against the driving box
which is stationary. This difference in
speed of revolution successively brings the 65
apertures 12 into alinement with the duct
13 and the lubricant (preferably soft
grease), not only lubricates the hub face of
the liner but also works through the aper-
tures 12 and lubricates the driving box face 70
of the liner as well as the face of the driv-
ing box. The shape of the apertures 12 is
such as to assist in forcing the lubricant
through the liner to the driving box face
as relative rotation takes place. It will be 75
apparent that while the surfaces of the hub
liner will be thoroughly lubricated there
will be no wastage of lubricant to speak of.
I have found by this arrangement that
the wear is so much reduced that I am en- 80
abled to entirely eliminate the dropping of
the driving wheels to take up the lateral
wear between general shoppings or over-
haulings of the locomotive, whereas with
heavy power it is frequently necessary to 85
drop the wheels at least once or twice be-
tween general shoppings, as before pointed
out. In applying the liners to new work,
I prefer to forge the liners in a single piece
as shown and place them on the axle before 90
the wheel. When applying the device to
engines already fitted up, the liner is forged
and turned and then sawed in two on one
side, after which it is heated on the back
opposite the cut, then twisted and shoved 95
over the axle into the recess in the hub,
after which it is driven true to shape. I
have found this apparently difficult opera-
tion to work out very successfully in prac-
tice. 100
Another method of applying these float-
ing hub liners to axles which may be used
if desired, is to part the liner on both sides,
clamp the parts in place and then weld the
parts together which may be done either 105
with the use of oxy-acetylene flame or by
an electric process. The device may also
be applied in some cases if desired by form-
