IHARNESS CORD FOR LOOMS Filed Aug. 10, `1929 al aa JN VEA/TUR 7554/? VPA YA/E A Timm/5X5 Patented June 24, 1930 TATE OSCAR V.

August 10, 1929.

rl his invention relates to harness cords for looms and itis the general object of the invention to provide a. durable form of attachment etween a harness frame and a harness cord formed of tiller cord.

Triarness frames of looms are raised and lowered by means of one form or another of mechanism, such as heads, -dobbies or cams, the lifting force being transmitted through flexible connections which pass over pulleys or sheaves carried in the arches of the loom. It is an important object of my present invention to provide means including a head which is so clamped to the steel cable core of the tiller cord as to be forced into the outer fibrous covering of the cord.

It is a further object of my present invention to remove a portion of the fibrous covering for the steel cable core and pass the same through the head, wrapping the cable upon itself and then binding it tightly between the head and a portion of the tiller rod.

A still further obj ect of my present invention is to provide improved connections between the cable and the head wherein the cable is held within the periphery of the head so as not to project where it may have contact with adjacent cords or other moving parts of the loom.

l/ilith these and other objects in view which will appear as the description proceeds, my invention resides in the combination of parts hereinafter described and set forth in the claims.

In the accompanying drawings, wherein a convenient embodiment of my invention is set forth,

lllhe loom frame or arch 10 has a pin 11 on i which is mounted a plurality of harness sheaves, one being designated herein at l2. Harness frames 13, one of which is shown in Fig. l, are raised and lowered by means of mechanism not shown to form the sheds between the warp threads. Heretofore, it has been customary to effect raising and lowering of the harness frames through flexible connections such as small rope or leather straps. Each harness frame is provided with a hoolr 14 which has connection with the flexible lifter.

ln carrying my invention into eect I provide each harness frame with a strap or connector 20 formed of tiller cord, the same having a core 2l which is made up of several strands of iieirible relatively fine steel wire. Surrounding this cable is a sheath of iibrous material 22 which resembles the ordinary cord used in certain classes of looms.

l remove a portion of the sheath 22 and extend the core or cable through holes 23 and 24- formed in a head or connector 25 which is preferably sheet steel. The portion of the connector' between the holes is ydepressed as at 26 in Fig. 2. The end of the cable is passed first through hole 23, then over the depressed portion 26, and then through the other hole 23, being bent back under the depressed part 26 and wrapped around a portion of itself between the depressed part and the sheath 22, as designated at 27.

In F ig. l I have set forth one of the steps in the manufacture of my cord and connector, the edges 28 and 29 being separated to define a substantially U-shaped cavity into which the fibrous covered end of the cable may extend, as in 6. After the steel core has been manipulated as described the straight end 30 will. be extended along that part of the sheath 22 which lies in the cavity defined between the edges 28 and 29. By means of appro priate tools these edges are then closed so that the head assumes the cylindrical form shown in cross section in Fig. 5.

The head is so proportioned that the edges 28 and 29 will force the end 30 into the fibrous sheath 22, as clearly shown on enlarged scale in Fig. 5. It is by the construction set forth in this latter figure that I am enabled to anchor the end of the steel core securely and at the same time prevent the fibrous sheath from working loose and drawing out of the head. The head ma)- have an extension with la perforation all to receive the hook 14.

From the foregoing it will be Seen that I have provided a very simple connection between a harness frame and tiller cord which includes a head havingi two holes through which the cord of the tiller top extends. The head has a depressed part between the holes over which the core extends, so that the latter will not project substantially beyond the periphery of the head. It will also be seen that by wrappingr the cord around itself as at 27 I provide additional friction the effect of which is to provide a tight bind tending to prevent the core from workingr loose. Furthermore, the end 30 of the cable is so placed as to retain the sheath of fibrous coveringlr 22.

Having thus described in v invention it will be seen that changes and modi tications mayY be made therein by those skilled in the art without departingr from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:

1. In a connector for loom harnesses, a flexible cord havin;r al fibrous sheath and a wire core, a head havingy holes through which the core extends, the core being wrapped on itseltl and beiner held embedded in the sheath by a portion of the head.

2. In a connector for loom harnesses, a flexible cord having: a fibrous sheath and a wire core. the sheath beiner removed near the. end of the cord and the core extendingr uncovered. a head through which the core extends, the end of the core lyingT between the head and sheath and being held embedded in the latter by the head.

3. In a connector for loom harnesses, a fiexible cord having a fibrous sheath and a wire core, a sheet metal head havingr a cylindrical portion into which both the sheath and the core extend. said head having holding: engagement with the core, the core beingY wrapped around itself and then extending between the sheath and the cylindrical portion of the head and beingY held embedded in the sheath b v the head, wherebvv the sheath and end of the cable are held against relative movement with respect to each other.

4. In a connector for loom harnesses, a flexible cord havingir a fibrous sheath and a wire core, a head having a hollow cylindrical body provided with a pair of spaced openings, the part of the head between the openings being depressed` the wire core extending through the openings and alonei4 the depressed part of the head, so that said core lies substantially within the periphery ot' the head, the core being: wrapped on itself and terminating within the head.

5. In a connector for loom harnesses, a flexible cord having a fibrous sheath and a wire core, a head having a hollow cylindrical body provided with a pair of spaced openings, the part of the head between the openings being depressed, the wire core extendinpr through the openings and. along the depressed part of the head, so that said core lies substantially within the peripheryv of the head, the core being wrapped on itself and terminating within the head, heilig held between the interior of the head and the sheath.

In testimony whereof I have hereunto affixed my signature.
