LOOM.

Specification of Letters Patent.

Patented J an. 22, 1918.

' Application filed June 19, 1917. Serial No. 175,564.

To all whom it may concern:

Be it known that I, FRANK SonwARz, a citizen of the United States, residing at Mc- Cleary, in the county of Grays Haidoor and State of lVashington, have invented certain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to looms and more particularly to portable hand looms and has for its principal object to provide a new and novel type of foldable and portable hand looms for weaving rugs and the like. Another object of my device is toprovide an improved and novel heddle construction which embodies alternate holes and slots. Still another object of my device is to provide a hinged and foldable heddle supporting standards which may be folded up out of the way when not supporting the heddle.

Other objects will appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a side elevation of my device with parts broken away. Fig. 2 is a fragmentary plan of same with parts omitted. Fig. 3 is a front elevation of my improved heddle and heddle supporting frame.

Referring more particularly to the drawings numeral 1 indicates sills which are arranged in parallel pairs, are secured together by cross timbers and are hinged at their adjacent ends to center cross timbers 2. At the outer ends of sills 1 end posts 3 are hinged and are normally held in a vertical position by means of removable braces 4. It will be noted that the end posts 3 may fold inwardly fiat against the sills 1. End posts 3 are channeled at their upper ends to provide a notch for supporting the head blocks 5. Stationary heddle posts 6 are erected on the cross timbers in line with the sills 1 and are provided at their upper ends with foldable heddle holders 7 which have heddle retaining grooves in their upper ends. One of the head blocks 5 is provided with a series of hooks 8 to which the ends of the warp threads 9 are secured, the other head block 5 is provided with holes through which the warp threads pass. Pegs 10 are used to contain the warp threads While they pass through head block 5.

After passing through the head block 5 the warp threads again pass through an inter mediate block 11 and thence to individual spools 12. My improved heddle 13 is provided with alternate parallel slots 14 and holes 15. The holes 15 are preferably located midway the length of the slots. Every alternate warp thread passes through one of the slots 14 and the other alternate threads pass through the holes 15 so that when the heddle is in position every other warp thread is slidable vertically with respect to the heddle and the remaining warp threads are fixed vertically with respect to the said heddle. In operation the heddle holders are folded down against the standards 6 thereby allowing free movement of the heddle which is grasped by the operator and is first depressed thereby separating the alternate warp threads as shown in Fig. 1. When in this position the bobbin containing the woof is passed horizontally between the depressed and normally positioned warp threads. The heddle is then brought up against the woof in order to drive it back solidly into the fabric. The heddle is returned to approximate position and is raised above normal position thereby drawing the alternate warp threads to a point higher than the normal warp threads and another woof thread is placed in position. It will be understood that the alternate normal threads are the ones which pass through the slots 14: and which remain approximately stationary whereas the other warp threads are the ones which pass through the holes 15 and which are alternately depressed and raised above the normal threads in order that the alternate warp threads may cross between each woof thread. For easement of transportation the end members 3 may be folded down against sills 1 and sills l in turn folded up vertically into position parallel with the posts 7 and the normal position of the heddle thereby forming a small and compact package.

WVhile I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit and scope of the invention, and I therefore desire to avoid being limited to the exact form shown and described.

Having described my invention, What I ed intermediate the said end posts, heddle claim as new and desire to protect by Letholders foldably mounted on the upper ends 10 ters Patent, is: of the said heddle posts, and heddle means In the device of-the class described the normally supported between the said heddle 5 combination of hinged sills, end posts hinged holders.
