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. 3 . . 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 3 Ul in the detailed description hereinafter following, when taken in connection with the accompanying drawings, in which:--- .» » Figure 1 is an elevation of Va strap and a harness tions.` shown infsection and with the adjusting sleeve or nut in a diiîerent- position;l Figure 10 is an isometric view of the adjusting sleeve or nut shown inl Figures 8 and 9; Figure 11 is a' view ofanother form of the in- , 5- ì venti'on-:which is especially adapted for heavy duty;v ' ' J Figure 12 is an isometric view of the adjusting> sleeves'or nuts shown in Figure 11; Figure 13 is another slightly modified form of lu the invention; IFigure V14 is a view similar to Figure 13 with portions shown in section and with the adjusting sleeve or nut in a different position; Figure l5 is anisometric View of the adjusting 15 sleeve or nut used in Figures 13 and 14. Figure 1'6 is a view, partly in section showing a modified form of Figure 2 and showing a coupler for wires, cables, rods and theY like. Y Referring more particularly to the drawings the 2o numeral IU indicates a conventional portion of a loom such as a yoke disposed thereabove on which a plurality of rollers I I are mounted, there being a roller for each of the cords I2 which im parts up and down motion to the harness frame 25 I3 during the weaving operation. To the lower end'of strap I2 is secured a downwardly extend ing threaded rod VI4 which has an enlarged offset portion I5 on the lower end thereof, said olîset portion having a smooth bore therein whichl is 30 penetrated by rod I6. The upperV end 'of rod I6 has an loiîset portion I 'I which also has a smooth bore therein and the bore is penetrated by threaded rod I4. f VThreadably mounted on rod I 4 is a sleeve or nut I8, having a beveled face I9y which is adapted to coincide with the lower face of enlarged portion I'l When the harness connector is in operative posi tion. It is evident that when sleeve or nut I8 connector associated therewith, connected to the 4 upper portion of a harness frame; Figure 2 is a side view of a portionA of Figure 1 on an enlarged scale with portions broken away; that relative movement is impossible on account 0f thebeveled surface I9 engaging the enlarged Figure 3 is a viewl of a modified form of the The lower end of rod,v I6> has a suitable hook 2l o2. invention; 4'5 - . » ì f ` . y - - _ ' Á „ ' >Figure 6 is a View similar to Figure 5 with por 50 tions shown in section; Y . .

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.
