The upper end of cord l3 is linked to a is a well known fact in the textile trade that the suitable ring and this ring, in turn, is linked 5 heddle frames of looms are raised and lowered to a bar Hi.

showing my invention applied thereto; as shown in Figures 1 and 2. It will be noted, 40

Figure 2 is an enlarged vertical sectional View wever, that eac e d o the top side 34 bends taken along the line 2-2 in Figure 1; back into the plane occupied by the sides 32 and Figure 3 is an exploded isometric View of the 33, thereby forming bearing portions 34a and buckle; 34b which accommodate the crotches 38 and 39 Figure 4 is a view of the parts shown in.

The clamp 40 is formed from one continuous the buckle as they appear when a strap is first bar and the ends of these parallel V-shaped end inserted therein; portions M and 42 are joined together by two Figure 5 is a view of my improved buckle showparallel bars 43 and id which in turn are disposed ing the same when being used with a slightly approximately at right angles to the V-shaped 50 different type of strap for raising and lowering a portions.

This bracket has position. 55

When it is desired to adjust the strap 26, the parts are placed in the position as shown in Figure 4, at which time the strap can be easily adjusted, relative to the clamp 40 of the member 21. After the strap has been properly positioned, the clamp 40 is turned through an angle of substantially degrees to the position shown in Figure 2 at which time the strap is tightly clamped between the side 34 and the roughened surfaces 43a and 44a of the parallel bars 43 and 44 respectively. This is accomplished by moving the hook 28 in a counterclockwise manner in Figure 4.

Figure 5 shows a slightly modified form of the invention in which my improved buckle is shown associated with an elongated strap 50. This strap has an eyelet 5i secured to the upper end thereof which is adapted to be linked to ring [6 when in an installed position on the loom. Also at this time, the lower end of the buckle will fit into the eyelet 29 of heddle frame 3| substantially in the same manner as shown in the preceding form. By using this elongated strap, the cord l3 as well as the parts 14 and I5 may be dispensed with. Of course, the upper portion of this strap, when used, must be turned through a quarter turn in order that the flat side thereof will rest on the top of the pulley l2, but at the same time allow the lower side thereof along with its associated buckle 2! to have its flat side lying in the same plane as the heddle frame 3|.

It is, therefore, seen that I have provided a harness connecting means whereby the height of a heddle frame may be easily and quickly adjusted without detaching the flexible strap from the raising and lowering means or the buckle from the heddle frame.

In the drawing and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for the purposes of limitation, the scope of the invention being set forth in the appended claims.

I claim:

1. A harness connector and strap for supporting the heddle frames of looms comprising a weblike strap, a buckle member having V-shaped ends on each end thereof, spaced members connecting the legs of one V-shaped end with the legs of the other V-shaped end, and a member having a loop on one end provided with a cam portion and a hook portion on the other, the apices of the V-shaped ends being adapted to rest in said loop on each side of the cam portion, and said web member being passed between the cam portion and the members joining the legs of the V-shaped ends together, 'so that when the member having the cam portion is rotated relative to the buckle member having V-shaped ends, the cam portion will push the web member past a straight line passing from one spaced member to the other spaced member.

2. A harness connector comprising a substantially rectangular member having opposed sides bent to substantially V-shape, a second member having an eye on its upper end substantially wider than the first member and through which the first member is adapted to be passed so that the loop member will rest in the apices of the V- shaped sides of the first member, the looped portion of the second member having an off-set portion so that when the two members are rotated relative to each other the off-set portion will move closer to the straight side portions of the first member to clamp a strap passed between the oiT-set portion and the straight side portions of the first member, said second member having a hook on its other end adapted to engage a heddle frame.

WILLIAM H. BAHAN.
