4 Claims. (Cl. 13933) The present invention relates to new and useful improvements in hand looms adapted for use in weaving various articles, such as small rugs or the like.

An important object of the invention is to provicle a hand loom having a single heddle mechanism of simple construction and including a comb which operates to move alternately warp threads above and below the normal plane thereof to facilitate the passing of the woof or weft therethrough by means of the usual shuttle or needle and to further construct the comb with split rings or eyes to facilitate placing of the warp in the comb and removing the same therefrom.

Another object of the invention is to provide a heddle constructed for swinging the comb toward either end of the frame of the loom to facilitate working of the weft closel at the ends of the frame at the start and finish of the oper ation.

A still further object is to provide means for slidably adjusting the heddle bodily longitudinally of the loom to enable uniform raising and lowering movement of the warp throughout the length of the loom.

Another object of the invention is to provide a loom frame having a pivoted frame member at one end thereof to release the warp of the finished article when removing the same from the frame.

A still further object is to provide a device of this character of simple and practical construction, which is eiiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details'of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a top plan View;

Figure 2 is a side elevational view;

Figure 3 is an end elevational view with parts broken away and shown in section;

Figure 4 is a longitudinal sectional view taken substantially on a line 4-4 of Figure 1;

Figure 5 is a similar View showing the heddle swung downwardly for moving the warp below the normal plane thereof;

Figure 6 is a transverse sectional view taken substantially on a line 66 of Figure 2;

Figure '7 is a transverse sectional view of the pivoted end frame member showing the same swung inwardly for releasing the warp;

Figure 8 is an enlarged view in elevation of one of the eyes of the comb; and

Figure 9 is a side elevational view thereof and showing the bevelled entrance to the eye.

Referring now to the drawings in'detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates generally the loom frame which 'is preferably of polygonal shape to provide a pair of side frame members 6 and end frame members I and 8. The side frame members -6 and end frame member I are fixedly secured to each other in any suitable manner and end frame member 8 is pivoted for vertical swinging movement on a transverse rod 9 carried by the adjacent ends of the side frame member 6.

A pair of locking pins Ba is provided for locking the pivoted end frame member 8 in its raised position. The upper edges of the end frame members 1 and 8 project upwardly above the side frame member 6 for a purpose more fully hereinafter explained.

A plurality of hooks I0 and II are suitably secured to the upper edges of the end frame members l and 8 with the hooks projecting horizontally inwardly and to which the strands l2 of the Warp may be attached and supported in spaced parallel flights between the hooks of the end frame members with end loops 82a on the warp l2 detachably attached, in any suitable manner, to the end frame member 8. 7 Screw eyes it are positioned on the upper edge of the end frame members I and 8 adjacent the ends thereof and in which rigid rods Id are removably supported in a position parallel to and in the plane of the warp I2. The rods [4 are positioned at each side of the warp and around which the woof or weft I5 is wound by means of the usual shuttle or needle I6 employed for feeding the woof transversely thereof.

Alternate flights or sheds of the warp 1 2 are raised and lowered b means of a heddle mechanism designed generally at I7 and comprising a substantially crank shaft construction to provide shafts I8 at each end of the heddle journalled in longitudinal slots I9 in the side frame members 6. Knurled knobs 20 are suitably secured to the outer ends of the shafts 18 to rock the latter for swinging the central crank portion 2| of the heddle vertically to raise and lower the same under the warp l2.

Coil springs 22 positioned on the end shafts I8' bear against the crank arms 23 and against washers 24 positioned on the shafts H3 at the inner sides of the side frame members to hold the heddle against idle swinging movement.

The heddle I! also includes a comb structure designated generally at 25 and comprising a plurality of rings or eyes 26 held in an upright position by shanks 21 rising from the crank portion 2| of the heddle. One side of each eye 26 is formed with an-entrance slot 28 and with the opposed ends of the slotted eye inclined or bevelled as shown at 29 to smooth the entrance slot on one side of the eye as shown more clearly in Figures 8 and 9 of the drawings. Alternate flights or sheds of the warp l2 are inserted through the slots 28 for positioning in the eyes 26 and with the eyes freely slidable on the warp longitudinally of the frame 5.

In the operation of the device the 'warp 1 -2 is anchored to the hooks in and l l at each end of the frame and with the eyes 26 of comb 25 carried by the heddle l1 engaging alternate flights or sheds of the warp. "The heddle l! is then rocked back and forth "by the 'knobs 20 to raise and "lower the "she'ds of the warp carried by the comb as sh'ow'n in Figures 4 and 5 of the drawings to enable passing of the shuttle or ricedle 1'6 transversely thereof to thus feed the weft I} through the warp and around the side rods l d'. The elevation of the end frame members 1 and 8 facilitate manipulation of the shuttle or needle wit'hout interference by the side frame members 15.

The heddle I1 isswingabl'e toward either end of the frame so that at the start ofthe weaving operation the sheds may be raised and lowered close "to the starting'end of the warp by sliding the heddle toward that "end :in the slot i9 and swinging the heddle toward the starting end of the warp tothus enable working o'f'the weft'close to the starting end of the article.

Likewise as theweaving approaches its finish or the opposite 'endof the frame the heddle fi' is moved longitudinally of the slot {9 and swung in a raising and lowering movement toward the finishend of the warp.

The springs 22 hold the shuttle in its slidably adjusted position as well as in its raised or lowered position.

After the weaving is completed the warp 'is released from the eyes 25 by sliding the same outwardly through the slots '28, the rods Ill are withdrawn from the endsof the weft I5 and the locking pins 'Ba withdrawn to permit the inward swinging movement 'of th'e'end frame member '8 to release the warp from the hooks "re and .l I. The loops l2'am'ay then be det'ached'to free the finished article.

In view of the foregoin'g'description taken in conjunction with the accompanying drawings it.

is believed that a 'clear understanding of the device will be quite apparent to those skilled'in this art. "A m-ore detailed'description is accordingly deemed unnecessary.

It is to "be understood, however, that even though there is herein shown described a preferred embodiment of the invention the same is susceptible to "certain changes f ul ly comprehended by'the spirit o'f'the invention as herein described and the scopeof the appended claims. Having described the invention, what-iis claimed as newis: g
