JOHN WESLEY HARRIS, OF PEARSALL, TEXAS.
COMBINED PIPE CLAMP AND WRENCH.No. 820,866.
To all whoin it may concern:
Be it known that I, JOHN WESLEY HARRIS,
a citizen of the United States, residing at
Pearsall, in the county of Frio and State of
5 Texas, have invented a new and useful Pipe
Clamp and Wrench, of which the following is
a specification.
This invention relates to improvements in
combined pipe clamps and wrenches, and has
io for its object to improve the construction and
increase the efficiency and utility of devices
of this character.
With these and other objects in view, which
will appear as the nature of the invention is
15 better understood, the invention consists in
certain novel features of construction, as here-
inafter fully described and claimed.
In the'accompanying drawings, forming a
part of this specification, and in which corre-
20 sponding parts are denoted by like designat-
ing characters, is illustrated the preferred
form of embodiment of the invention, capable
of carrying the same into practical operation,
it being understood that various changes in
2K the form, proportion, and minor details of
construction may be resorted to without de-
parting from the principle or sacrificing any
of the advantages of this invention within
the scope of the appended claims.
30 In the drawings, Figure 1 is a perspective
view from beneath of the improved device,
and Fig. 2 is a plan view. Fig. 3 is a side ele-
vation of the device applied.
The improved device comprises two body
35 members 10 11, having recesses 12 13 in their
contiguous edges for bearing upon opposite
sides of the pipe to be clamped, the latter in-
dicated at 14 in Fig. 3.
The device herein shown and described is
4o designed for use more particularly for sup-
porting the suction-pipes in wells of various
kinds, such as tubular or Artesian wells, where-
in a tubular curbing is employed, and a por-
tion of such a curbing is represented at 15 in
45 Fig. 3, with the body members 10 11 clamped
upon the pump-tube 14 and bearing upon the
upper end of the curbing, and thus support-
ing the tubing suspended within the curbing.
To increase the efficiency of the device and
50 extend the bearing-surface, the members 10
11 are formed, respectively, with lateral
ribs 16 17 with their lower faces flush with
the lower faces of the members 10 11, as
shown. By this means a relatively broad
55 bearing-surface is presented to the upper edge
of the curbing, which materially increases thePatented May 15, 1906.
utility and efficiency of the device and dis
tributes the strains over a wider area, while
at the same time securing a uniform pressure
upon all parts of the curbing and also of the 6o
clamping members.
At one end the members 10 11 are formed-
with overlapping ears 18 19, through which a
pivot-pin 20 passes, the pivot-pin having a
head 21 at one end preferably bearing in a re- 65
cess 22 in the ear 18.
The pin 20 is provided with a portion
threaded intermediate its length, as at 23, to
receive a nut 24, bearing upon the face of the
ear portion 19, thus leaving a portion of the 70
pin unthreaded and extending beyond the
bearing-nut, as at 24.
At their opposite ends the members 10 11
are coupled by a clamp-bolt 25 and its nut 26
and operating at right angles to the pivot 20, 75
so that the operation of the nut 26 will firmly
clamp the members 10 11 upon the tubing.
The head portion 27 of the bolt 25 is held
from rotation by a rib 28, extending from the
member 11, as shown. 8o
It frequently happens that the tubing 14 is
to be wholly or partly rotated while bearing
upon the curbing 15, and when this occurs
the extension portion 24 of the pivot-pin 20
is employed to serve as a fulcrum or rest for 85
a wrench lever or bar 29, which is disposed
with one end, as 30, against the tube or pipe
14 and with the intermediate portion bearing
against the unthreaded portion 24 of the
pivot-pin. By this simple means a very 90
strong leverage power is exerted upon the
pipe to rotate it.
Having thus described the invention, what
is claimed is-,
1. A tubing-clamp consisting of two body 95
members having recesses in their contiguous
edges for bearing upon the tube from oppo-
site sides and with laterally-extending ribs at
the edges whereby a relatively broad bearing-
surface is provided at one side, said members moo
having overlapping ears at one end, a pivot-
pin extending through said ears and with a
head upon one end and threads disposed in-
termediately of the pin, whereby an unthread-
ed portion of the pin extends beyond the ears 105
at one side to form a bearing for a wrench-
arm, and a clamp-bolt operating through the
opposite ends of the body members.
2. A tubing-clamp consisting of two body
members having recesses in their contiguous I10
edges for bearing upon the tube from oppo-
site sides and with overlapping ears at oneSpecification of Letters Patent.
