JOSEPH WILLMANN, OF NEW BRAUNFELS, TEXAS.
PIPE-COUPLING.
SPECIFICATION forming part of Letters Patent No. 717,647, dated January 6, 1903.
Application filed March 8, 1902. Serial No. 97,345. (No model,)To all whom it may concern:
Be it known that I, JOsEPH WILLMANN, a
citizen of the United States, residing at New
Braunfels, in the county of Comal and State
5 of Texas, have invented a new and useful
Pipe-Coupling, of which the following is a
specification.
This invention has for its object to produce
a device whereby the abutting ends of two
to pipes may be coupled or connected without
the necessity of forming threads thereon ; and
the-invention consists in the improved con-
struction, arrangement, and combination of
parts, to be hereinafter more fully described,
15 whereby the coupling or connecting of pipes
may be speedily and effectively performed.
In the accompanying drawings, Figure 1 is
a side elevation showing two joints of pipe
connected by my improved coupling. Fig. 2
20 is a sectional side elevation of the same.
Fig. 3 is a transverse section taken on a plane
intermediate the heads or disks of the coup-
ling.
Corresponding parts in the several figures
25 are indicated by like characters of reference.
5 and 6 designate the ends of two sections
or joints of pipe connected by my improved
coupling. The latter comprises in its make
up two disks or heads 7 and 8, having ceu-
3o tral apertures whereby they are fitted upon
the ends of the pipes to be connected and
provided with additional apertures to receive
connecting-bolts 9 and 10, having nuts 9" and
10a,whereby the said disks or heads may be
35 forced in the direction of each other. Any
- desired number of connecting-bolts may be
used; but only two have been shown in the'
drawings, inasmuch as this number will be
usually found sufficient. Each of the disks
40 is provided with radial recesses or cavities,
as 4, extending outwardly from their inner-
peripheries, said recesses or cavities being
practically nothing more than notches, all of
which are of substantially the same size and
15 shape, so that the disks may be reversed or
transposed without interfering with the util-
ity of the device.
11 and 12 designate bars rectangular in
cross-section, so as to fitin the notches 4, and
5o provided at one of their ends with wedge-
shaped projections, (designated 14 and 15.)
It will be observed that the construction ofthese elements, which may be described as
" wedge bars," is identical and that they have
been referred to by different numerals only 55
in order to distinguish their relative disposi-
tion, as will be presently seen. .
The disks which form the heads or ends of
the. coupling may be provided with any de-
sired number of notches 4. When the disks .6o
are to be used upon small pipes, four will
usually be found sufficient. Upon larger
pipes six, eight, or even a larger number
may be used. It will be observed, however,
that the number of notches should always be 65
even in order to enable the wedge-bars to be
properly disposed; also that the said notches
will naturally be formed equidistantly from
each other.
In the carrying out of my invention one of 70
the disks is adjusted upon each of the pipe-
sections to be united near the end of the same,
and the wedge-bars are then adjusted in the
notches of said djsks,with their wedge-shaped
ends alternately pointing in opposite direc- 75
tions. Thus when the wedges are driven
lightly home in the notches of the opposing
disks the parts of the device will be tempo-
rarily held upon the pipes which are thus
loosely connected. A washer 24 should be 8o
previously inserted between the meeting ends
of the pipes, as shown. The bolts connect-
ing the disks are now placed in position and
the nuts tightened thereon. The tendency
will now be for the disks to move in the di- 85
rection of each other and to engage the
.wedges of the reversely-disposed wedge-bars,
eachdisk thus obtaining throughthe medium
of the engaging wedge-bars a very firm grip
upon the adjacent pipe-section. When the 90
disks are engaged by the wedges so solidly
that each disk will be incapable of further
movement longitudinally upon the pipe-sec-
tion upon which it is mounted, a continued
tightening of the nuts will result in forcing 95
the abutting ends of the pipe-section very
tightly together and into contact with the in-
terposed packing, thus forming an absolutely
tight and very durable joint.
It will be observed that the wedge-bars, 'c o
which are clamped by the disks upon each
pipe-section, while incapable, as well as the
engaging disk, of further longitudinal move-
ment with relation to the pipe-section upon
