ping element 11 of the upper gripping
member. Said bars 25 are further provided
with a fixed gripping element 27 corres-
ponding in all respects to the fixed grip-
5 ping element 17 of the upper member. -
In operation, as will be apparent from
the drawings the pipe is passed vertically
between the fixed and movable gripping
elements of the lower gripping member and
10 between the similar elements of the upper
gripping member. In this position the fixed
javs of both gripping members will cooper-
ate, assuming the pipe is to be lifted with
the upper jaws of the movable gripping
15 elements of each member, so that the pipe
will be. initially held by the inwardly con-
vergent gripping edges of said jaws. As
the operating lever is lowered the upper
gripping element is in effect moved out-
20 wardly causing .the movable gripping ele-
ment 11 to more tightly force the pipe
against the fixed jaw 18, the upward move-
ment of the pipe freeing the movable ele-
ment 26 of the lower gripping member from
25 a 'gripping action on the pipe incident to the
pivotal mounting of said element 26. When
the lever is released and moved downwardly
for a new grip the spring 24 forces the for-
ward end of the lever 20 downwardly with
o0 the effect to force the upper jaw of the grip-
ping element 26 of the lower member into
gripping cooperation with the pipe holding
the pipe against the fixed jaw 27. A repeti-
tion of this operation causes the pipe to be
3 gradually elevated to the desired extent.
In lowering the pipe the upper gripping
member is the medium for gripping the pipe
during the release of the lower gripping
member, said latter member in this instancebeing operated by foot pressure upon the 40
foot extension 23 of said lever 20.
The detailed formation of the jaws of the
respective movable and fixed gripping ele-
ments is particularly important in that it
prevents the slipping of the pipe and in- 46
sures a firm hold thereon under all condi-
tions. The pivotal mounting of the mov-
able gripping elements 11 and 26 are further
important as it compels a comparatively
extensive movement of the elements for the 50
gripping operation while at the same time
affording sufficient space for the passage of
couplings or the like on the pipe in the re-
lease position of said movable gripping ele
ments. 55
It. is of course to be understood that the
various parts are to be constructed of such
material and in such relative sizes as will
best adapt them for the particular char-
acter of pipe being operated upon, and that 6o
aside from the essential details hereinabove
described, I in no wise limit myself as to
shape, size or material of the parts.
What is claimed is:
A pipe grip comprising a pair of spaced 65
bars, a strip pivoted at a point adjacent to
the extremities of said bars, said strip hav-
ing its ends bent at right angles to form
gripping surfaces, and a grip element se-
cured to the bars and having its gripping 70
surface positioned to one side of the pivotal
connection of said strip.
In testimony whereof I affix my signature
in presence of two witnesses.
