is claims, (cl. :està-6_1)
This invention relates to a harness connector
and more especially> to a harness-connector which
has means for accurate screw adjustment where
bythe height of the harness can be adjusted and
5 will remain in adjusted position without vthe
necessity of .disconnectingthe harness connector.
or cordvfrom the harness.
>
In many harness connectors, heretofore used,
this adjustment has been unsatisfactory because
10 it ls impossible to obtain'minute and permanent
adjustments as to the height of the harnesses. It
is, therefore, an object of this invention to pro
Vide arharness connector, the overall length of
which may be varied without the necessity of de
15 taching either the harness frame or cord from
the connector.
,
'
'
It is a further object ofrthis invention to pro
vide means on a harness connector which will
26
maintain the adjustment `in the same position
during the operation of the loom. It is a well
known fact that when leather or other ñbrous ma
terial isfused for a connector that a certain
amount of stretch will occur and cause the shed
to bind the shuttle in its travel. Since the overall
length of my harness connector will not vary after
25 it has been placed Vin operative position, it is
evident that each.r harness frame will maintain
the same relation with respect to the cords at all
times.

The invention is notonly applicable to harness
connections, but may be used for coupling any
two members together such as rods and the like.
Some of the-objects of the invention having
been stated,'the .invention will more fully appear

cavity in portion I '|.
In Figures 5, 6 and 7 another form of the in
vention is shown in which cord I2 has secured
shown by slightly raising the harness frame I3
thereto a threaded rod or shank 26 which pro
jects downwardly and penetrates a smooth bore
in the upper end of a. body member 21. The cen
tral portion of member 21 has a slot therein form
10 ing sidewalls 28 and 29 which are adapted to en
gage head portion 30 disposed on the lower end
of rod 26 and act as guides for holding the lower
portion of rod 26 in its proper position. It will be
noted by referring to Figure '7 that portion 3B has
lugs 3| integral therewith which engage sidewalls
28 and 29 and prevent lateral or rotative move
ment of rod 26. A sleeve or nut 32 with pointed
projections 33 on the upper end thereof is thread
ably secured on rod 26. 'I'hese projections are
adapted to ñt into a suitable notch disposed in
the upper end of the body member 21 when .the
connector is in operative position. By `slightly
raising the harness frame I3 and turning sleeve
or nut 32 the necessary adjustment can be made
as to the height of the harness frame.
Figures 8, 9 and 10 show another form of the
invention similar to that shown in Figures 5, 6
and 7, but instead of using a sleeve or nut 32, a
sleeve or nut 35 having an extension sleeve por
30 tion 36 is used which is adapted to threadably
engage the shank or rod 26. Sleeve portion 36
penetrates a bore 31 in the upper end of body
member 21 and prevents the threads on rod 26
from becoming scarred or mutilated when the
connector is in operation. The head portion of
sleeve or nut 35 has pointed projections 38 on
the upper end thereof which are identical to theprojections 33 on sleeve or nut 32.
Figures 1l and 12 show a form similar to those
40 shown in Figures 2 and 3. Cord I2 has secured to
the lower end thereof a downwardly extending
threaded rod 40 which has integral with lower
end thereof an oiîset enlarged portion 4|. This
portion has a smooth bore therein which is pene
45 trated by an exension sleeve 42 integral with a
sleeve or nut 43. Projections 44 are made inte
gral with sleeve or nut 43 and are adapted to
engage suitable notches in enlarged portion 4|
to hold the nut 43 in position. Nut 43 and ex
50 tension sleeve 42 are threadably secured on an
other rod 45. which projects upwardly and has on
the upper edge thereof an offset enlarged portion
46 similar in all respect to portion 4|. Another
extension sleeve 42 with a nut 43 integral there
55 with is adapted to penetrate a .bore in portion 46
and this extension sleeve and nut are threadably
mounted on rod 46.l This type of harness con
nector is particularly adapted for use in heavy
work where greater strength and stability of the
60 harness connector is desired together -with quick
and turning the adjusting sleeves or nuts. This
can be done without detaching the connector and Ul
when the adjustment has been made it remains
in this same position until the harness frame is
again Vraised by manual means. It is also evi
dent that there is no way for the connector to
become disconnected and allow the harness frame
to drop.
Figure 16 shows a coupler which can be used,
not only as a harness connector, but for coupling
any two members together, and like reference
characters apply, except adjusting sleeve or nut 15
I8 has an extension sleeve Ißa to protect the
threads on member I4. Member I4 instead of
being connected to cord I2 has a hook |8b. It is
thus seen that hooks 2| and |8b can be connected
to any desired objects for adjustably connecting 20
the same together.
In the drawings and speciñcatlon there has
been set forth a preferred embodiment of the
invention, and although specific terms are em
ployed, they are used in a generic and descriptive
sense only and not for purposes of limitation, the
scope of the invention being set forth in `the ap
pended claims.
