vided with a depending ear . 28 working
snugly within the longitudinal slot 28a pro-
vided in the casting or yoke 5, and a feed or
adjusting screw-29 is journaled through that
end of the casting or yoke 5 having the bear-
ing 6, and is threadedly engaged through
the lower portion of the ear 28. The screw
29 is restrained against longitudinal move-
ment, and may rotate readily, to slide the
clamp member longitudinally, and that end
of the screw 29 which projects beyond the
bearing 6, is equipped with a suitable hand
wheel 30 for facilitating the rotation-of the
screw. A depending clamping bolt 31 is
16 threadedly engaged to the other end of the
base 25, and works within the longitudinal
slot 32 provided in the yoke or casting 5, the
head of the bolt 31 projecting below the
slot 32 for assisting in clamping the base 25
20 of the clamp member upon the yoke or cast-
ing 5.
The invention also embodies a bolt hold-
ing device, which includes an. upstanding
fork 33. having its shank 34 journaled or
26 pivotally engaged to or through the casting
or yoke.5, and a screw 35 is engaged slidably
through the arms of the fork 33 at right
angles with the fork, and a hand wheel 36
is disposed snugly between the arms of the
30 fork and is threaded upon the screw 35.
Thus, the screw 35 is restrained for longitu-
dinal movement, through the fork 33, and
the wheel 36 is restrained for rotary move-
ment, in order that when the hand wheel is
45 rotated, the screw 35 will be moved longitu-
dinally as desired. A lever 37 is fulcrumed
to the shank of the screw 35, and is equipped
adjacent its fulcrum, with. a bit.38 for en-
gaging the kerf of the head of a tire bolt.
40 The present apparatus employs a crane or
carrier 39. for supporting and manipulating
the wheel which is being operated upon.
The crane 39 includes a horizontal beam 40
having a slotted.casting 41 bolted or other-
45 wise secured to one end thereof and piv-
otally engaged over a pintle or bearing 42
secured to the standard of the frame 1. An
inclined base 43 has its upper end secured to
the free end portion of the beam 40 and has
50 its lower end pivotally engaged to a bearing
member 44 attached to the lower end portion
of the standard 4. The beam 40 is thus
capable of being swung in a horizontal plane
toward one side or the other of the frame 1.
55 The crane or carrier 39 may be held at
various angular positions, .by means of a
brace or adjusting bar 45 pivoted to the free
end of the beam 40, and having a series of
lower notches 46 adjacent its free end, which
60 notches are engageable over an outstanding
arm or bracket 47 rigidly secured to the
standard 4. Thus, by disengaging the brace
or bar 45 from the arm or bracket 47, the
crane may be swung to the position desired,
s5 and by engaging the proper notch 46 of thebrace or bar 45 over the bracket 47, the crane
may be held in the position to which it has
been swung. -
The beam 40 carries a slide 48 which is
capable of rectilinear or reciprocatory move- 70
ments upon the beam, and the slide 48 is
equipped with an upstanding spindle 49 for
the engagement thereover of the wheel hub.
Adjustable wheel supporting means is pro-
vided, and embodies a lever 50 fulcrumed to 75
one side of the slide 48, and a bar 51 having
its lower end pivoted to the lever 50 and
provided at its free or upper end with a hub
seat 52 loosely embracing the spindle 49 and
adapted to carry the hub of the wheel. The 80
said side of the slide 48 is provided with an
arcuate series of notches or sockets 53 into
which is engageable, a peg or pin 54 for
holding the lever 50 at various adjusted
positions, to thereby support the hub seat 52 E5
at various vertical positions, as desired.
An actuating rod 55 for the slide 48 is dis-
posed immediately above the beam 40 and is
engaged slidably through the slide 48, and
the inner end of the rod 55 is linked to a bell 90
crank lever 56 fulcrumed within the casting
41. The slide 48 carries a set screw 56a for
clamping the rod 55 in position relative to
the slide, and whereby the slide may be ad-
justed longitudinally relative to the rod ac- 95
cording to the various circumstances. A
rod or link 57 has its upper end attached to
the lever 56 and has its lower end connected
to a treadle 59 by means of a strip ,7a. The
treadle is fulcrumed to the base and is raised 100
by a spring 58, and the lower end of the
strip 57a is pivoted to the treadle. The
lower end of the link 57 is engaged through
the upper angular end of the strip 57a and
adjusting nuts 57' are threaded upon the 105
lower end of the said link. This treadle 59
when depressed, will draw the link 57 down-
wardly, to thereby draw the rod 55 inwardly
or toward the fulcrum of the crane beam 40,
and consequently, the slide 48 will be moved 110
inwardly with the rod 55. When the treadle
59 is released, the spring 58 will return the
corresponding parts to normal or initial
position.
In operation, the hub of the wheel 60 is 115
placed over the upstanding spindle 49 of
the slide 48, and the hub seat 52 is set prop-
erly by adjusting the lever 50, in order
that the wheel 60 will be supported.in the
proper horizontal plane. The slide 48 is 120
also adjusted longitudinally along the beam
40 and with respect to the rod 55, by loosen-
ing the set screw 56a, in order that the wheel
felly or rim will have its inner side resting12
against the jaw 26. The base 25 of the 125
clamp member is adjusted relative to the
bearing 6, in order that the recess or open-
ing 27 will receive the wrench member 15,
and thereby the wrench member may pro-
ject through the jaw 26 to engage the cor- 1302.
