Oct. 20, 1953 H. L. G. BERGLUND HAND WEAVING LOOM 2 Sheets-Sheet 2 Filed NOV. 18, 1950 mvEN-ro HIL-MA .G. BERGLUND ATTO RN E1s Patented Oct. Z0, 1953 UNITED STATES l OFFICE 5 Claims.

This invention relates generally to looms and particularly to a loom constructed to permit the work to be removed in its entirety, and other work to be quickly placed therein.

It has always been a problem in the art of weavingto prepare a loom for the weaving operation, This is a long and tedious job, takingv from twelve to twenty-four hours, and requires that each long thread be individually threaded through a number of relatively small openings, and then securely mounted on the cloth roll having previously been attached to the warp roll.

It is an object of my invention to provide a loom structure from which the rolls, the heddle frames, and the reed may be quickly and easily removed to permit the work in its entirety to be replaced with other work in a quick, easy operation.

It is another object to provide a loom in which the heddle frames are placed in individual frame guides and are individually received in pusher cradles which are connected with individual hand levers for selectively raising the individual frames by a pusher action, leaving the top of the loom open and unobstructed to facilitate removal of the frames,

It is a further object to provide a removal and carrying frame structure adapted for easy attachment to the heddle frames, the reed, and the rolls to permit easy removal. of all of said elements simultaneously.

These and other objects and advantages of the invention will more fully appear from the following description made in connection with accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which Fig. 1 is an exploded perspective view of the main loom structure with the removable elements shown thereabove, and the removal and carrying frame structure illustrated at the top; and

Fig. 2 is a transverse vertical sectional view showing the carrying frame connected to the heddle frames, reed and rolls.

As illustrated in the drawings, I provide a loom structure having a suitable base designated as an entirety by the numeral 5, and having the upstanding capes disposed at the four corners thereof, A breast beam and a back beam 8 reythe warp in the conventional manner.

spectively interconnect the two front capes 6 and the two rear capes 6. A pair of opposed stationary frame guides 9 are respectively fixed to the ends of the base structure 5, and each has a plurality of frame guiding channels 9ct formed thereinA Each pair of opposed channels has a heddle frame Ill slidably received therein. Each heddle frame has a plurality of horizontally spaced heddles ida having the heddle eyes IOb centrally formed therein. The heddles Illa are stretched between longitudinal frame rods IIlc and the heddle eyes ISU serve to position one group of threads from A plurality of heddleframe lever cradles II are normally in lowered position supported by the cushioned stop I2, as best shown in Fig. l. Each lever cradle II has a frame-receiving groove formed therein to receive the lower rail of the 4heddle frames I0 which are supported on the cushioned rests I2a. These cradles are adapted to be individually raised as by the levers I3, which are pivotally connected thereto, and swing on the pivot iixed in the base structure 5, A

ipush button or handle I3a is xed to the outwardly extending end portion of each lever I3, and a spring tensioned latch plate I4 is swingably mounted on the end portion of the base structure 5, and has a slot Ma formed therethrough for each of the levers I3. yMc; has a st op projection i5 formed therein to Each slot receive the respective depressed lever I3 and hold lthe same in depressed position. When the outwardly extending end portion of one of the levers I3 is depressed, the respective cradle I I fixed .thereto is elevated and the heddle frame Hi received in the cradle groove is pushed up to raise the threads extending through the heddle veyes Ib to permit the weaving operation to be 'carried on in the conventional manner` It should be noted that whenever one of the levers I3 is pressed downwardly the camming surface immediately above the respective stop projection I5 is engaged to shift the entire plate I4 against the force of the spring I4b, and any of the other levers which are down during this shifting move- ,ment will be released to drop the particular heddle frame raised thereby.

A pair of rotatable rolls IB and I1 arerespectively mounted at the front and back of the loom structure, as by being respectively rcceived in the slots 6a formed in the front and back pairs of capes 6. Suitable keeper plates 6b are pivotally mounted on the respective capes 6 and normally retain the trunnions of the rolls within the respective slots 6a. A pawl and ratchet mechanism positively holds each of the rolls against rotation. A pawl Ila is mounted on at least one front and one back cape B, and toothed ratchets are respectively mounted on the rolls I6 and I1 to maintain tension on the cloth and warp respectively wound thereon,

A batten I8 is swingably mounted on a suitable rod I9 and a reed 20 is removably anchored in the upper portion of said batten, as best shown in Fig. 2. The upper batten bar I8a is vertically adjustable on said batten as by the elongated slots Ib, and the bolts and wing nuts I8c securely clamp said batten bar against the reed 20. The elongated slot |817y permits reeds of various width to be used, and these slots extend upwardly through the upper ends Aof the batten uprights to permit the top bar I8a to be entirely removed and permit the warp extending through the reed 20 to be removed bodily from the mounting structure along with the reed and heddle frames.

A removal and carrying frame, designated as an entirety by the numeral 2l, is provided and has an overhead support frame with a carrying handle 22 xed at its ends to cross bars 23. A pair of heddle frame receiving cross slats 24 are swingably mounted on blocks l25 fixed to the underside of the respective cross bars 23. One of the slats 24 in Fig. 1 is shown in closed position, while the other slat is shown in open position. A pair of slat retaining latch members 25 are Ymounted in transversely spaced relation to the blocks 25 and *respectively receive the end portions of the slats 24, as illustrated. A pair of reed hooks 21 are slidably mounted on rod 28 which extends between cross bars 23, and two pair of roll clips 28 are connected to the respective ends of said cross bars 23, as by the exible elements .29.

The following is a description of the operation of my improved loom structure. The rolls I6 and I7 are mounted in their respective slots 6a, and the heddle frames ID are mounted in the respective frame guiding channels 9a, of the guides 9 and are received in the grooves in cradles II. The reed 2li is inserted in the batten I8 clamped between said top bar Ia and the lower grooved bar disposed forwardly and below said top bar Ia, as best shown in Fig. 2. The loom is prepared for weaving in exactly the same way as conventional looms and is operated during the weaving operation in the same manner as conventional looms. The heddle frames are selectively vertically reciprocated by the levers I3. The warp, of course, extends upwardly from the warp roll I1 at the rear of the loom and over the back beam 8, through the respective eyes Ib of the heddle frames I0, through the reed 20, and the cloth extends over the breast beam 7 to the cloth or front roll I6 on which the woven cloth is Wound.

In order to remove the frames, the reed and the two rolls I6 and I1, along with the work, the top batten bar I8a is removed from the batten to release the reed 20 and the two beams 'I and 8 may be removed from the respective capes 6, which is permitted by the removable dovetail joints therebetween. The rolls I6 and I'I can now be released from their respective slots and clipped to the roll clips 28, the reed being received in the hooks 21 and the upper rails of the frame being supported on the cross slats 24, which are, of course, swung into closed position to retain the same thereon. This permits the entire work, the heddle frames, the reed, and the rolls to be bodily removed by lifting the removal and carrying frame 2 I.

It will be seen that I have provided a relatively simple, yet highly eicient and ingenious mechanism for permitting work to be bodily removed from a loom for inserting a separate piece of work without requiring the work to be replaced to be removed from the reed, heddle frames and rolls, thus permitting easy connection and eX- change of work pieces, while lusing the same main loom structure. This is particularly valuable where weaving is being taught and permits each student to set up his or her own loom extremely quickly and easily without requiring a sepa-rate base structure for each student.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departure from the scope of the present invention, which, generally stated, consists in the matter shown, and described, and set forth in the appended claims.

What I claim is:
