Application May 8, 1940, Serial No. 333,882 2 Claims. (01.139-33) This invention relates to toy looms and particularly to toy looms of the type adapted for use in schools, kindergartens and also in the home to provide both occupation and instruction in weaving for children.

One object of the invention is to provide a loom of this type which is equipped with two sets or groups of heddles and means for operating them in such a Way as to produce a plain o weave body fabric, and which is' also equipped with a plurality of additional heddles capable of independent operation and adapted to carry pattern warp threads, said additional independently operable heddles providing a simple means by which a pattern can be woven into the completed fabric.

In order to give an understanding of the invention, I have illustrated in the drawing a selected embodiment thereof which will now be described, 29 after which the 'novel features will be pointed out in the appended claims.

In the drawing:

Fig. 1 is a longitudinal-sectional view of a loom embodying the invention.

Fig. 2 is a section on the line 2-2, Fig. 1.

.Fig. 3 is a fragmentary side view showing the shedding mechanism.

Fig. 4 is a fragmentary plan view showing the cloth roll.

30 In the drawing, l' indicates a loom frame which is herein shown as in the form of an open-topped box-member having a bottom 2, side walls 3 and 4, and end walls 5 and 6. As stated above, the

. loom embodies in its construction two groups or "sets of heddles, together with means for alternately raising and lowering the two sets to produce warp sheds for the production of a body fabric, together with a series of individual independently operable auxiliary heddles by which a 40 pattern may be woven into the fabric.

The heddle mechanism for weaving the plain weave body fabric may have any suitable or usual construction. As herein shown, the heddles of the two groups are indicated at 1 and 8 respec- 45 tively, each heddle of the group I being provided with a heddle eye 9, and each heddle of the group 8 being also provided with a similar heddle eye Ill. The warp threads II for forming the body fabric are threaded through the heddle eyes 9 50 and ID, as usual in the looms adapted for plain or tabby weaving.

In the construction shown, these heddles 1 and 8 are in the form of cords which are attached to and carried by rollers l2 and I3 that are rotatably mounted in standards M rising from the side walls 3 and 4 of the frame I, the upper roller l2 being situated above the box-like frame, and the 1 lower roller l3 being located within said frame.

The heddles 'l and 8 may be made as individual heddles or one of the heddles l and the adjacent heddle 8 may be made as a continuous cord which is looped about the rollers l2 and 13 in such a Way that the sides of each loop cross each other between the rolls, as seen in Fig. 1. Each loop is secured to the roll 12 'by means of a suitable fastener 4|.

In threading up the loom, the alternate warp threads II are threaded through the heddle eyes 9 of the heddles I and the remaining warp threads II are threaded through the heddle eyes l5 H] of the heddles 8.

Means are provided for turning the roller I2 thereby to produce warp sheds. When the rollers are in the position shown'in Fig. 1, the heddle eyes 9 of the heddles I are in raised position, and the heddle eyes I0 of the heddles 8 are in lowered position. A rotation of the roller [2 counterclockwise through 180 will shift the heddles so as to bring the heddle eyes H! of the heddles 8 into raised position, and the heddle eyes 9 of the heddle 1 into lowered position, thereby to produce another shed.

For thus operating the roller l2, the latter may be provided with a pin 20 extending from the end thereof and which acts as a crank by which the roller can be turned. One of the uprights 14 is provided with stop shoulders 2i which cooperate with the pin to limit the turning movement of the roller 12. A spring 22 connected at one end I to said pin and the other end to the loom frame serves to hold the roller I2 yieldingly in either of its two positions.

The warp threads I I are shown as being wound on a warp beam 42 which is carried in brackets 'manipulated shuttle, and the filling may be beaten up in any approved way as by means of an ordinary comb.

The structure as thus far described is adapted to weave a plain foundation fabric. To provide for weaving a pattern in the fabric, I propose to employ a plurality of independent auxiliary heddle elements 23 arranged in a. single row extending across the loom, each auxiliary heddle having a heddle eye 24 to receive one of the pattern warp threads 25. Any desired number of these auxiliary heddles 23 may be employed and I have herein shown them as situated in front of the rollers l2 and IS. The lower ends 26 of the auxiliary heddles 23 are received between and are guided by two upright walls 21, 28, that extend across the box-like frame I from one side wall 3 to the other side wall 4. The heddle members 23 preferably extend somewhat above the upper roller 12, and each heddle is provided at its upper end with a finger piece 29 by which it may be lifted. When any auxiliary heddle 23 is in its lowered position, resting against the bottom 2 of the box-like frame i, the corresponding pattern warp thread 25 will be in lowered position and in the lower half of the warp shed which is formed by operation of the rollers l2 and I3.

Each heddle 23 can be raised individually into an elevated position, thereby to carry its pattern warp thread 25 into the upper half of the warp shed. Each heddle 23 is provided on its rear face with a recess 30 which provides a hook portion 3|, and extending across the frame above the latter is a supporting bar 32 on to which the hook 3! of any heddle 23 may be hooked to hold said heddle in raised position. This bar 32 is shown as supported by uprights 33 situated at the sides of the loom frame.

In operating the device, the roller I2 is first turned in one direction and then in the other, thereby to form successive warp sheds in the body warp threads II, a pick of filling being inserted into each shed as usual in weaving. To produce a pattern in the fabric, the auxiliary heddles 23 are selectively raised at proper times and hooked onto the bar 32, thereby bringing selected pattern warp threads 25 into the upper half of the shed. One or more of the auxiliary heddles 23 may be raised for each pick or for certain selected picks, depending on the character of the pattern which is to be woven in the fabric. So long as the auxiliary heddles 23 are in their lowered position, the pattern warp threads will lie along the under face of the fabric, and whenever the pattern' calls for any of the pattern warp threads 25 to appear on the upper face of the fabric, then the corresponding heddle or heddles 23 will be raised and hooked onto the bar 32 for one or more picks, depending upon the character of the pattern.

By thus employing a plurality of auxiliary heddles 23, each of which can be independently raised and lowered, it is possible to weave a wide variety of designs into the fabric.

The lower ends 23 of the heddles 23 fit freely in the space between the vertical walls 21, 28, and to provide for the rearward movement of each heddle 23 necessary to hook it over the bar 32, the lower front corner of each heddle 23 is cut away or chamfered, as shown at 34.

The advantage of making the loom frame in the form of an open topped box is that said box provides a compartment 39 in which a child may store various articles which he uses in connection with the operation of the loom. The guiding walls 21, 28, extend nearly to the upper edge of the box-like frame and thus prevent any articles from accidentally getting into the space between said walls and interfering with the complete lowering movement of the heddles 23.

Any desired number of heddles l and 8 may be employed, and the loom may be set up so that there will be a plurality of body warp threads I I between each two adjacent heddle elements 23.

Although I have shown one form of heddle mechanism for manipulating the body warp threads H to form the body fabric, yet I wish it understood that other known heddle mechanism may be used for this purpose without departing from the invention.

I claim:

1. A toy loom comprising a loom frame, two sets of heddles carrying body warp threads, means for raising the sets of heddles alternately to form warp sheds for weaving the body fabric, a plurality of independent individual auxiliary heddles situated in front of the two sets of heddles, each auxiliary heddle carrying a pattern warp thread, two guide walls extending across the loom frame and between which the lower ends of the auxiliary heddles are received and by which they are guided, each auxiliary heddle having a hook portion, and a supporting bar extending across the loom and over which the hook portion of any individual auxiliary heddle may be hooked, thereby to support said heddle in raised position.

2. A toy loom comprising a loom frame, two sets of heddles carrying body warp threads, means to raise the sets of heddles alternately to form warp sheds for. weaving a plain fabric, a plurality of separate individual auxiliary heddles situated in front of the two sets of heddles, each auxiliary heddle carrying a pattern warp thread and having a hook portion on its rear side above the pattern warp thread carried thereby, each auxiliary heddle being capable of being manually operated to raise or lower its pattern warp thread independently of any other auxiliary heddle and also independently of the sets of heddles, a heddlesupporting bar extending across the loom between the auxiliary heddles and the two sets of heddles, means for supporting said bar permanently in fixed position, whereby at the formation of each shed, any desired auxiliary heddle can be selectively raised at will by the operator and hooked over said bar, thereby carrying its pattern warp thread into the upper half of the shed, and means acting on the lower ends of the auxiliary heddles for guiding them in their rising and falling movement.

JOHN C. BROOKS.
