8. E. GREEN Jan. 25, 1955 HARNESS CORD FOR LOOMS AND METHOD OF MAKING SAME INVENTOR. BERNARD E. GREEN ATT 03. N EY Filed March 27, 1951 United States Patent O HARNESS CORD FOR LOOMS AND METHOD OF MAKING SAME Bernard E. Green, Shrewsbury, Mass. Application March 27, 1951, Serial No. 217,765 3 Claims. (Cl. 139-88) This invention relates to improvements in cords employed in suspending and manipulating the harnesses of looms and has particular reference to novel means and method of making and providing said cords with connection end members.
One of the principal objects of the invention is to provide harness cords of the above character which are extremely resistant to wear,
of oils, which during use and having improved connection means adjacent the opposed ends thereof whereby the said cords will more positively retain their connected relation with the harnesses and with the wires for manipulating said harof such cords in looms.
of use and having connection means secured to its opposed ends in the form of initially tubular shaped members having a portion thereof overlying the ends of the cord and anchored in crirnped relation therewith and another portion thereof anchored to a looped end of the cable by compression of the walls of said portion and by thereafter cupping said compressed portion to a semicircular cross-sectional shape of a width no greater than the width of the initial diameter of its tube and having the portion of the looped end of the cable bindingly anchored therein and further having a connection opening formed through said compressed walls and in alignment with the looped end of the cable.
Other objects and advantages of the invention will become apparent from the of construction, arrangement of parts, and steps of the method shown and described without departing from the spirit of the invention as expressed in the accompanying I, therefore, do not wish to be limited to the exact details of construction, arrangement of parts and steps of the method shown and described as the preferred form only is given by way of illustration.
Referring to the drawings:
Fig. 1 is a side elevational view of the device embodying the invention and diagrammatically illustrating its use;
Fig. 2 is a side elevational View partially in section of a tubular member from which one of the attachment or connection ends of the device is formed;
Fig. 3 is a fragmentary side elevational view of one end of the cord preparatory to assembling the tubular member of Fig. 2 therewith in forming one of the connection ends;
Fig. 4 is an enlarged sectional view of one end of the device illustrating the tubular member of Fig. 2 in reposition of the end of the core preparatory to performing a subsequent operation thereon;
Fig. 5 is a view generally similar to Fig. 4 illustrating a still further step of the method and showing the completed attachment or connection end member;
Fig. 6 is an enlarged sectional view taken as on line 7-7 of Fig. 5 and looking in the direction indicated by the arrows; and

attached to the harnesses.
conventional These cords are quiring periodic replacement.
One of the major objects, therefore, of the present invention is to provide cords of the above character which will retain their intial length during use, which are much more res stant to wear, less susceptible to deterioration, and having connection end portions which will overcome the prior art difficulty of becoming loose and detached during use or throughout the life of the cord.
Referring to the drawings, the cord 9 embodying the 1nvent1on is diagrammatically illustrated in position of use, that is, in assembled relation with a sheave 10 and connection end portions 11 in conthe conventional hook portions 12 of a harness 13 and the hooked end 14 of the conventional of polymeric chlorosimilar material which is resistant to attack by oil and which is extremely resistant to wear. The said covering 17 is of a controlled diameter to properly fit within the circumferential In forming the cord, the opposed ends are cause a portion of the inner core 16 to extend outwardly thereof a considerable length as shown in Fig. 3. bular member 18, as shown in Fig. 2, having its inner bore 19 of a diameter slightly less than the outer diameter of the covering 17 and having an opening 22 extending therethrough is placed over the end of the cord, as illustrated in Fig. 4 by first forming the extended member them in alignment. The portion of the tubular and flathaving the loop 20 therein is then compressed tened by striking it with another die section to respect to each other with no interference by the ends of the cord. It is particularly pointed out that one of the walls 25 of the tube when cupped as stated above, particularly the outer side wall, curves inwardly toward the longitudinal axis 26 of the cord along a sweeping are as illustrated best in Fig. 7, which are will intersect the longitudinal axis 26 at a point slightly spaced from but adjacent the outer end 27 of the flattened portion. The inner wall 28 is cupped to a cross-sectional arc of a radius less than the cupping of the outer wall 25 whereby the respective edges 29 and 30 of the flattened portion will be moved inwardly, as illustrated in Fig. 6, an amount sufiicient to position them a distance apart substantially equal to the initial diameter of the tube. It is further pointed out that although the flattened end is curved as illustrated in Figs. through 7, the said spaced walls 25 and 28 still retain a binding gripping relation with the looped portion of the cable.
It is further pointed out that although the connection opening 22 is described as being formed in the tube at the initial stage of the process, as illustrated in Fig. 2, the said opening 22 may be formed through said inner and outer walls and 28 centrally of the loop 20 after the end has been cupped. I
By reference to Fig. 7, it is to be noted that the wall 28, while cupped inwardly about a radius less than the radius of the outer wall 25, it is also cupped inwardly in a sidewise direction toward the wall 25 about a radius 31 which is less than the sweeping radius of curvature of the side wall 25 in said direction. The upper end portions 32 and 33 of said spaced walls 25 and 28 are in substantially parallel relation with each other throughout the area occupied by the opening 22.
It is particularly pointed out that the inner and outer walls 28 and 25 will be in binding pinching relation with the looped portion 20 of the core throughout the length of said substantially parallel portions 32 and 33 and will provide a wide area of gripping and holding relation with the said looped portion 20.
Although the crimpings 21 are shown as being formed only in one diametrically opposed relation, similar crimpings may be formed in a substantially perpendicularly diagrammatically opposed relation, if desired, in addition to said first named crimping.
The ends 11 are preferably placed in assembled relation with the hooks 12 and 14 with the said ends curving inwardly with respect to the opened portions of the hooks, as shown best in Fig. 1, whereby said ends will remain more permanent in attached relation with said hooks and will not become disconnected therefrom.
From the foregoing description, it will be seen that simple, eificient and economical means have been provided for accomplishing all of the objects and advantages of the invention.
