HEDDLE STOP MOTIOI I: FOR LOOMS.

Application filed July 18, 1922. Serial 110. 575,781.

which will act also in the capacity of a stop motion for looms.

Another object of the invention is to provide a heddle wherein the yarn may be threaded into the eye without disconnecting the heddle 'or without using an instrument,

the heddle being formed with means sup-- ported by the yarn acting as a stop motion attachment.

A still further object, more specifically, is to provide a heddle and stop loom wherein a pair of heddle strips are used for the combined purpose of holding the yarn and guiding a stop strip held inplace by theyarn when the parts are in o erative position and permitted to drop for c osing an electric circuit when any yarn is broken.

In the accompanying drawing- Figure 1 is a fragmentary elevation of a heddle frame with a pair of heddles ar-' ranged therein disclosing an embodiment of the invention, the same being shown in connection with a stop motion circuit.

Figure 2 is a sectional view through Figure 1 approximately on line 22.

Figure 3 is a plan view of the two heddle strips and stop motion strip shown in Figure 1 by numerals, 11 indicates a heddle frame of any desired or preferred kind provided with the usual top and bottom bars 12 and 13 and the usual end bars 14. The heddle supports 15 and 16 are of the usual type which receive the slotted ends of the strips 17 and 18 which make up. the heddle 19. Associated with these, strips and arranged therebetween is a stop motion strip 20 which is a flat strip preferably of'the same width as the strips 17 and 18 and also preferably slightly longer so that the upper end may be provided with the usual slot 22 for accommodating the support 15. It will be noted that-the slot 22'is' longer than the support 15'is wide which is also true of the lower slot 23 so that when not supported the strip 20 may drop down and the point 24 engage the contact bar 25. This contact bar is provided with an insulating covering 26 designed tocover the entire bar except the upper part, said barbeing also insulated from the frame 11 and connected by wire 27 to a suitable source of current 28. The heddle frame 11 is connected by wire 29 to an alarm 30 which is shown as a bell and also by a wire 31 to a switch or other. mechanism used for throwing off the power to the loom so as to stop the same;

The wire 32 also extendsto the same switch,

as wire 31 and a suitable connecting wire 33 connects wire 32 to the bell30.

By this construction and arrangement, whenever the stop motion strip 20 is in its elevated position, no current will flow either to the mechanism for throwin out the switch or other power nor to the bell 30 but in case one of the yarns 34 should break, the particular strip 20 supported thereby would drop down under the action of gravity until the point 24 engages the contact bar 25. As one side of the bell 30 .is grounded on the frame 11, this would cause a closing of the circuit and the bell immediately begin to ring and the mechanism for shutting off the power would be operated, said mechanism being of any desired or usual.

ty e. v 7 lirom Figure 3 it will be observed that the heddle sections or strips 17 and 18 are rovided with notches 35 and 36 merging mtp eye openings 37 and 38, which openings register and form an eye for the yarn 34 when the parts are in operative position. The strip 20 is provided with an inclined slot 39 whereby this strip may rest on the yarn 34' and be supported thereby normally but permitted to drop by gravity, when the yarn breaks. The various strips 17, 18 and 20 are,

all flexible and are preferably made out of flexible steel strips so that a yarn may be easily placed into he eyes by bowing these strips 1n opposite directions and forcing the yarn through by hand.

What I claim is v 1. A heddle and stop motion for looms, comprising a heddle frame, a pair of strips forming a heddle carried by said frame, a comparatively large opening 21 as well as ;ings, a third strip having an opening for.

receiving the same yarn that extends through the openings of the heddle, said third strip being supported by said yarn,.a contact bar positioned to engage said third strip when the same is. moved downwardly a predetermined distance, and means connected with said contact bar for shutting off 7 the power of the loom.

2. A combined heddle and stop motion, comprising a heddle frame, a heddle formed of two strips provided with an eye for receiving the yarn, a stop motion 'striparranged between the first mentioned strips provided with means acting as an eye for receiving said yarn, said stop motion strip being supported by said yarn, said stop motion strip having an elongated opening near the (top, a contact bar extending through said opening, and electrically operated means connected with said bar and the heddle for giving a signal when the stop mo tion strip moves downwardly under the action of gravity a predetermined distance.

3. In a combined heddle and stop motion for looms, a heddle frame, a heddle formed of two strips positioned side by side, carried by said frame, and a stop motion strip arranged between the first mentioned strips.

4:. In a combined heddle and stop inotion,

-a heddle frame, a heddle structure formed of two strips having means presenting an eye for a yarn, a stop strip arranged be tween said heddle strips formed with a notch for receiving said yarn so that the stop strip may be supported by a yarn, said stop strip having an elongated opening at one end, a

contact bar extending through said opening whereby when said yarn breaks, the stop strip may fall and engage said contact bar,

and an electric circuit adapted to be closed by said stop strip when the same engages said contact bar.

5.,In a combined heddle and stop for openings, and an alarm strip arranged between the first mentioned strips, said alarm strip having an opening for receiving saidyarnwhereby it is supported;

7. A heddle-detector, comprising a pair of thin fiat strips having registering yarn receiving openings, each ofsaid openings being formed with a notch extending inwardly from one edge of the respective strips and merging into an enlargement, the enlargement of the opening of one strip registering with the enlargement of the opening of the other strip, with the remaining parts of the respective notches out of alignment.
