From the foregoing description, it will be ap
parent that the wrench of the invention is simple
of construction, requires a minimum of adjust

that a wrench with cleats arranged to ?t any
desired type and size of hub ?ange may be in-,
The following is claimed:
1. In a device: for rotating a part of a work
piece of the type having a member mounted for
reciprocatory movement toward and from a work
piece, a wrench keyed to said member and
adapted to be brought into engagement with a
part of a work piece during movement of said
member toward the work piece, and to rotate
relative to the member while in engagement with
said part upon further movement of said member
toward the work piece, the improvement com
prising stop means mounted adjacent the recipro
catory member and movable from a position out 40
of engagement with said reciprocatory member
to- a ‘position engaging said reciprocatory mem
ber and means actuated electrically only on alter
nate strokes'of said member toward the work
piece to move said stop means into engagement
with'said reciprocatory member in order to limit
the extent of reciprocation thereof and thus to
limit the extent of rotation of said wrench.
2. A device according to claim 1 in which said
wrench and said reciprocatory member are
formed with cooperating parts permitting said
Wrench to rotate in one direction from its origi
nal position, relative to said member, to another
predetermined position, relative to said member,
while in engagement with said part upon move
ment of said member toward the Work piece, and
then to rotate in the reverse direction relative to
said member upon movement of said member
away from the work piece until it has returned to
work piece, and then to throw said switch open
upon the next succeeding stroke of said reciproca
tory member away from the work piece.
6. In a device of, the type including a verti
cally disposed non-rotatable shaft mounted for
longitudinal reciprocatory movement toward and
from a work piece, a cylinder rotatively mounted
upon said shaft, a wrench keyed to said cylinder
so as to rotate therewith upon engagement with
a part of said workpiece during downward move
ment of the shaft, the improvement which
comprises a detent mounted adjacent said shaft
and movable from a position out of engagement
with said shaft to a position engaging said shaft
and electrically actuated means responsive to the
movement of said shaft, to move said detent into
engagement with said shaft on alternate strokes,
limiting the downstroke of ‘said shaft to control
the angle of rotation of the wrench.
7. The deviceaccording to claim 6 wherein said
stop means comprises a member adaptedto en
gage said reciprocatory shaft, a solenoid adapted
to thrust said member into and out of engage.
ment with said reciprocatory shaft, connected in
series with an electric switch adapted to be
thrown open upon one full reciprocation of said
shaft; and then to be thrown closed upon the
next succeeding full reciprocation of said shaft,
and a second electric switch adapted to be thrown
closed prior to each downward stroke of said
reciprocatory shaft and to be thrown open prior
to each upward stroke of said reciprocatory shaft.
8. The device according to claim 7 including
means associated with said reciprocatory shaft
for automatically actuating said ?rst switch upon
completion of each full reciprocation of said
9. A device according to claim 7 including
means responsive to the control of an operator
to actuate said second switch upon completion of
each stroke of said reciprocatory shaft, whereby
said stop means engages said reciprocatory shaft
on alternate downward strokes thereof so as to
limit rotation of said wrench, whereby when the
' work piece is a flyer having a ?anged ?yer wire
locking hub, reciprocation of the shaft causes
the wrenchv part: to engage the ?ange and to
rotate it on the ?rst stroke into wire unlocking
position and on the second stroke into wire look
ing position.
' '10. A device according to claim 9 wherein said
wrench part is so positionedas to rotatably en
gage a ?ange of a ?yer hub on one downstroke
immediately after said wrench begins to rotate
said original position.
and on the other downstroke after said wrench
3. The device according to claim 1 including
has rotated through an arc of 90°, and said ?rst
means for'electrically actuating saidstop means
and second switches are thrown closed on said
comprising, connected in series in an electric
?rst-mentioned downstroke of said switch so as
circuit, an electric switch adapted to be thrown
to limit rotation of said wrench to 90°, and said
open upon one'full reciprocation of reciprocatory (. ?rst switch is thrown open on said last-mentioned
member and then to be thrown closedupon the
second downstroke of the shaft so as to allow
next succeeding full reciprocation thereof, and a
rotation of said wrench to a full ‘180", whereby
second switch adapted to be thrown closed upon
the wrench part engages androtates a ?yer hub
each stroke of said reciprocatory member toward
the work piece, andvto be thrown open upon each ‘
strokeof said reciprocatory member away from
the work piece.
‘l. The device according to claim 3 including
meansadapted to reciprocate with said recipro
catory mcmber'to operate vsaid ?rst switch upon
?ange through an arc of 90° into wire unlocking
position on the ?rst stroke, and on the second
stroke rotates through the ?rst 90°'arc, then en
gages the flange and rotatesit "through a further
arc of 90° intowire locking position.
@111: In‘a device.‘ for rotating a part of a' work
piece of. the type having a wrench mounted on
the free end of a sleeve dependent from a spiral
nut, which nut rides on a spiral shaft‘mounted
15. In a device of the type including a ver
tically disposed spiral shaft mounted for longi
tudinal reciprocatory ‘movement toward and from
for reciprocatory movement toward and away
a work piece, a spiral nut riding on said shaft,
from the work piece, saidwrench being adapted
a sleeve dependent from said nut and rotatable
to- be brought into engagement with the part of
therewith, and a wrench carried by the free end of
the work piece to be rotated, the combination
said sleeve so as to rotate upon engagement with
comprising means adapted when actuated to
a part of the work piece during downward move
limit the angle of rotation of the part of the work
of the shaft, the improvement which com
piece by the wrench by limiting the extent of
electrically actuated stop means limiting
movement of the shaft member toward the work 10 the downward stroke of said shaft to control the
piece and electrical means for actuating said
angle of rotation of the wrench whereby when
limiting means.
the work piece is a ?yer having a ?anged ?yer
12. The device according to claim 11 wherein
wire locking hub and said wrench is moved down
said last mentioned means comprises a solenoid
to engage the hub flange and rotate the
adapted when energized to actuate said limiting 15 ward
hub, rotation thereon is stopped when the ?yer
means, a normally open energizing circuit for
wires are unlocked.
said solenoid and means for closing said circuit
only on alternate strokes of said member toward
the work piece.
13. The device according to claim 12 wherein 20
said circuit closing means comprise a pair of
references are of record in the
series connected switches, means movable with
?le of this patent:
said member for reversing the condition of one
of said switches on each stroke of said member
toward the work piece and means for maintaining»
the other of said switches closed during each
stroke of said member toward the work piece and
for maintaining such latter switch open during
movement of said member away from the work
14. The device according to claim 13 including
power means for moving said member toward the
work piece and operator controlled means for
coupling said power means to said member, said
last mentioned switch being mechanically con 35
nected to said operator controlled means for
closure thereby.
