grips arranged in the jaw and relatively
movable, a bearing on the jaw at one end of
the group of grips and means for locking the
grips, said means pressing upon the other
5 end of the group, an opposing jaw, and
means for operating the jaws, substantially
as described.
17. In combination a jaw, a series of grips
on the jaw, an opposing jaw, said grips being
10 movable radially in relation to the space be-
tween the jaws and having outwardly ta-
pered bodies, wedges tapered inwardly to-
ward the center of the said space, means for
pressing on the end members of the sets of
15 wedges and grips to lock them to the jaw,
and means for operating the jaw, substan-
tially as described.
18. A wrench comprising a pair of jaws
movable relatively to each other, gripping
20 means carried by each jaw, comprising a
series of members movable in relation to
each other and to the jaws, means for exert-
ing a locking pressure against the end mem-
ber of each series, in a direction lengthwise
25 of the series and from member to member of
each series and a handle for operating the
jaws.
19. A wrench consisting of a pair of
curved jaws said jaws being relatively mov-
30 able, a series of gripping members carried
by each curved jaw and having movement
relatively to each other to position them-
selves in conformity with the object to be
gripped, locking means for the series of
35 gripping members exerting its locking force
longitudinally of the series of gripping
members and a handle for operating the
wrench, substantially as described.
20. A wrench consisting of a pair of
40 curved jaws, said jaws being relatively mov-
able, a series of gripping members carried
by each curved jaw, said members being rela-
tively movable, and the end members of each
series being held against movement in the
45 longitudinal direction of the series, means
for exerting pressure upon the members of
the series at the other end thereof to cause
relative displacement of the members, and
means for operating the wrench, substan-
50 tially as described.
21. A wrench comprising a jaw having a
channel in its inner face, a series of grip-
ping devices carried by the jaw in said chan-
nel, means for applying pressure at the end
55 of the series of gripping devices and ex-
erting said pressure lengthwise of the series
for crowding the grips in the space be-
tween the jaw and the object to be manipu-
lated, whereby said gripping devices will
60 accommodate themselves to the surface of
the object and will be held locked in their
relative positions, a second jaw opposite the
one first mentioned and a handle for operat-
ing the wrench, substantially as described.
65 22. A wrench having a movable jaw, aseries of gripping devices movable in rela-
tion to and carried by the jaw and adapted
to accommodate themselves to the surface of
the object held between the jaws, and means
for applying pressure at the end of the series 70
of gripping devices, and exerting said pres-
sure lengthwise of the said series to crowd
said devices in the space between the sur-
face of the object and the jaw, and thereby
grip the object, a second jaw opposite the 75
one first mentioned and a handle for operat-
ing the wrench.
23. In combination in a wrench, a jaw,
a plurality of grips movable relative to each
other and carried by the jaw to be set to 80
engage the object, an opposing jaw, said
jaws having relative movement, a handle.for
closing the jaws, grip setting means lo-
cated adjacent the junction.of the jaws for
setting the grips in locked condition against 85
the object and a connection extending along
the handle for operating the grip setting
means.
24. In combination in a wrench, a jaw,
grips and interposed wedge members car- 90
ried by and movable relative to the jaw, an
opposing' jaw, said jaws having relative
movement, a master wedge member operat-
ing at the junction of the jaws to set the
grips, a handle for operating the jaws and 95
means operated from a point on the handle
for operating the master wedge member.
25. In combination in a wrench, a jaw,
a plurality of grips movable relative to and
carried by the jaw, an opposing jaw, means 100
for relatively operating the jaws from a
point distant from the jaws, and means for
locking the grips operated from a point
distant from the front of the jaws, substan-
tially as described. 105
26. In combination in a wrench, a curved
jaw, a series of gripping members carried
by said jaw and having movement relative
to each other, to position themselves in con-
formity to the object being gripped, lock- 110
ing means for the series of gripping mem-
bers exerting its locking force longitudi-
nally of the series of gripping members, a
second jaw opposite to that first mentioned,
and means for operating the jaws and set- 115
ting the grips, substantially as described.
27. In combination, a jaw bent to partly
embrace the object, grips movably carried
by said jaw and as a series conforming to
the shape thereof, a second jaw opposite the 120
first jaw, a handle for giving said jaws a
relative movement and means operating
substantially at the junction of the jaws
for operating the grips, substantially as de-
scribed. 125
28. In combination, a jaw bent to partly
embrace the object, grips movably carried
by said jaw and as a series conforming to
the shape thereof, a second jaw opposite the
first jaw, a handle for giving said jaws a 130
