representing the wheel-rim or felly; B, the I
spokes; C, the hub, and D D the clamping-
flanges that are mounted upon the end por-
tions of the hub and respectively are clamped
5 against the spokes by screw bolts or rivets.
In order to adapt the machine to straighten
a wheel of the construction specified, and rep-
resented in Fig. 1, the machine further con-
sists of a nut - plate 11, having a suitable
10 length and a flat body centrally perforated
and threaded in said perforation. A pres-
sure-screw 12 of suitable length is provided
with a cross-handle 12" or other means for its
manual rotation, and the threaded lower por-
15 tion thereof is screwed through the tapped
hole in the center of the nut-plate when the
device is in service. A carrier-sleeve 13 is
seated upon the nut-plate 11 concentric with
the pressure-screw 12, said sleeve having suf-
20 ficient length to engage its upper end with
the lowermost hub-plate D, when the wheel-
rim A is imposed upon the frame members
6, and thus supported horizontally.
Assuming that the wheel is placed on the
25 frame-bars 6a, as shown in Fig. 1, and is
firmly secured thereon by a clamping adjust-
ment of the screws 9, the bracket-arms 7 and
the rock-arms thereon being located between
spokes of the wheel, so that the inclined mem-
30 bears sa of said arms will be forcibly impinged
upon the frame-bars 6, this will dispose the
hub of the wheel centrally in the frame-ring
5, so that the pressure-screw 12 may be passed
down through the hub and then screwed a
35 suitable distance down thi ough the nut-plate
11 into contact with the carrier-bar 10. It
will be noted that the pressure of the screw
12 on the carrier-bar 10 will by means of the
carrier-sleeve 13 be transmitted to the lower-
4o most disk or plate D, and through said plate
raise the hub C sufficiently to remove an ob-
jectionable degree of dish had previously by
the wheel. The straightening of the wheel
having been effected by means of the machine
45 as described, this readjustment of the spokes
of the wheel will produce gaps between the
hub and spokes in the mortises occupied by
the tenons on the spokes, and to prevent the
latter from moving in the mortises, so.as to
50 again become improperly dished, the gaps
mentioned may be filled with molten lead or
other soft metal, thereby securing the spokes
solidly in the hub, the operation then being
completed by clamping the plates D against
55 the spokes C.
As shown in Fig. 2, the improved wheel-
straightening machine may be advantageously
used for straightening wagon - wheels or, in
other words, for reinoving excessive dish
6o therefrom if the wheels are manufactured
completely of hard wood, with the exception
of the tire. To this end the nut-plate 11 is
provided with two screw-holes, one near each
end of the same, and two pressure-screws 12aare employed, which in service are screwed 65
down through these threaded perforations in
the nut-plate and into enforced engagement
with the carrier-bar 10", the lowermost band
on the hub seating upon the nut-plate.
It will be seen that when the wagon-wheel 70
A' is imposed upon the frame members 6" and
clamped thereon by the screws 9 the machine
will be adapted for the removal of excessive
dish in the wheel by screwing the pressure-
screws 12" through the nut-plate 11 and 75
thence into contact with the carrier-bar 10",
said screws causing the hub of the wheel to
rise from the carrier-bar 10".
It is to be understood that in any case where
the-spoke-tenons have become loosened after 80
a correct dish has been given to the spoke
this dish may be rendered permanent by fill-
ing the crevices between the spoke-tenons and
the hub with molten metal or other available
material. 85
The improvement is also adapted for use as
a means for supporting vehicle-wheels when
tires are to be shrunken thereon. To this end
the wheel may be held in place by means of
the central clamping device and- the rim- 90
clamping means be displaced, so that the pe-'
ripheral surface of the wheel-rim is fully ex-
posed, and thus adapted for receiving a hot
tire, which may be conveniently placed in po-
sition, as the wheel is supported at a con- 95
venient height from the ground or floor where-
on the machine stands.
Having thus described my invention, I claim
as new and desire to secure by Letters Patent-
1. A wheel-straightening machine,embody- 1o0
ing a frame having depending legs, a horizon-
tal carrier-bar on the frame, means carried
by the frame for clamping a wagon - wheel
thereon, a nut-plate, a sleeve extending be-
tween a flange on the wagon-wheel and the nut- 105
plate, and a pressure-screw working through
the nut-plate and bearing upon the carrier-
bar.
2. A wheel-straightening machine, embody-
ing a frame-ring, frame-bars extended later- 110
ally from the frame-ring, depending legs on
the frame-bars, wheel-clamps mounted upon
the frame-bars, a carrier-bar on the frame-
ring, a nut-plate, and a pressure-screw work-
ing through the nut-plate and bearing on the 115
carrier-bar.
3. A wheel-straightening machine, embody-
ing a frame-ring, a plurality of spaced frame-
bars having engagement at one end with the
frame-ring and each provided with a depend- 120
ing leg at the other end thereof, a carrier-bar
hung by its ends transversely in the. frame-
ring, an elongated flat nut-plate, a sleeve seated
on the nut-plate and upbearing a wheel-hub,
the rim of which is clamped upon the frame- 125
bars, and a pressure-screw passing down
through the wheel-hub, working through the
nut-plate and bearing upon the carrier-bar.2
