molten metal may be introduced at the inner
ends of the wheel-boxes and allowed to en-
tirely fill the interval between the surfaces of
said box and spindle, whereupon, after cool-
5 ing, the spindle is provided with a sheath or
sleeve 16, constituting a new spindle-surface;
but in order to prevent this sleeve from turn-
ing upon the spindle the latter, prior to the
operation, should be thoroughly cleaned and
z0 provided with one or more grooves or depres-
sions 17, whereby when the molten metal has
flowed into the axle-box it will also fill said
depressions and thereby form keys 18.
After adjusting the wheel-clamp and spac-
15 ing the axle-seats on the base to correspond
with the interval between the axles the ve-
hicle is canted to dispose the extremities of
the axle-spindles in the cups of the seats,
whereupon the bearing of the outer ends of
2o the hub-sleeves or the shoulders usually pro-
vided at the outer ends of the hubs upon the
axle-nuts will dispose the wheels respectively
in planes perpendicular to the axles; but in
order that there may be no tendency upon
25 the part of the wheels to occupy positions at
an angle to the axle and also in order to in-
sure the uniform flowing of the molten metal
around the spindles it is desirable to plumb
the axles with the means provided for that
30 purpose or other means analogous thereto.
After having attained the desired vertical
position of the axles they may be so held,
manually, during the pouring operation, or
they may be fastened by any suitable ap-
35 paratus. (Not shown, and consequently no
part of my present invention.) The specific
form illustrated in the drawings is desirable'
by reason of the facility with which it can
be applied to the axles and also by reason of
40 the simplicity of its construction, the same
being applicable to axles of various construc-
tions and sizes without affecting its effi-
ciency in the capacity of indicating a verti-
cal position of the axles. It is obvious that,
45 the wheel-clamp, in addition to preventing
rotary movement of the wheels during the
repairing operation, prevents the swinging
of the front or steering axle of the vehicle,
and hence maintains the parts firmly in the
50 proper position for seating the axle extremi-
ties in the cups.
Furthermore, I have found in practice that
it is desirable in order to facilitate the re-
moval of the wheels after the operation, as
55 above indicated, to fit in the inner end of
each hub a forming-strip 19, of pasteboard
or equivalent material, of cross-sectionally
tapered or wedge-shaped construction. The
exterior surface of this forming-strip accu-
6o rately fits the inner surface of the hub, while
the inner surface thereof is beveled to pro-
duce a beveled shoulder on the sleeve formed
by the Babbitt metal, and this beveled sur-
face has the further effect of causing oil,
65 which works inwardly upon the axle-spindle,
to flow back upon the spindle to avoid waste;
also, the abrupt inner surface of the enlarge-,meant or collar 20, constructed within the
forming-strip, constitutes a dust -guard to
prevent sand and other foreign substances 70
from gaining access to the surface of the
spindle.
It frequently happens that the axle-box has
become interiorly scored or grooved by sand
or foreign substances which have worked into 75
the same, and in order to prevent the molten
metal from gaining access to these grooves
and thus forming keys to prevent the wheel
from turning upon the spindle I have found
it necessary in certain cases to cover such 8o
depressions, as by means of paper, tempo-
rarily fastened by an adhesive material to
the inner surface of the axle-box.
Various changes in the form, proportion,
and the minor details of construction may be 85
resorted to without departing from the spirit
or sacrificing any of the advantages of this
invention.
Having described my invention, what I
claim is- 90
1. An axle-repairing apparatus, having a
supporting-bar provided with spaced caps for
supporting the extremities of the front and
rear axle-spindles, in combination with means
for securing the wheels which are mounted 95
upon said spindles from accidental displace-
ment, substantially as specified.
2. An axle-repairing apparatus, having a
supporting-bar provided with spaced spindle-
seats for supporting the extremities of front 100
and rear axle-spindles, one of said seats being
adjustable longitudinally of the bar, and
means for securing the adjustable seat at the
desired adjustment, in combination with
means for clamping the wheels which are 105
mounted upon said front and rear axle-spin-
dles, to prevent accidental displacement, sub-
stantially as specified.
3. An axle-repairing apparatus, having a
supporting-bar provided with seats to receive zi o
the extremities of the front and rear axle-
spindles, one of which is adjustable longitudi-
nally of the bar, means for securing the ad-
justable spindle-seat at the desired adjust-
ment, and pivotal sills mounted upon the bar 115
for lateral extension to prevent displacement
thereof, substantially as specified.
4. An axle-repairing apparatus, having a
supporting -bar provided with spaced seats
to receive the extremities of front and rear 120
axle-spindles, and pivotal sills fulcrumed in
the transverse planes of said seats and adapt-
ed to be extended laterally to project beyond
the side edges of the supporting-bar, said bar
being of sectional construction and having 125
its members hingedly connected for folding,
substantially as specified.
5. An axle-repairing apparatus having a
wheel-clamp provided with means for simul-
taneously engaging front and rear vehicle- 130
wheels to prevent rotary movement thereof
upon their spindles and also prevent pivotal
movement of the front-wheel axle, in combina-
tion with means for seating the axles of the2
