`An adjustable weaving loom made up of a plurality of loom
`sections, each of which has a top surface with :1 plurality of
`generally equally spaced upstanding knobs. The loom sections
`are held together by socketlike joints in which a projection on
`one loom section is inserted into an opening on an adjacent
`loom section. The cross section of the projection and opening
`are such that relative turning movement between the two sec-
`tions is prevented.

`ADJUSTABLE WEAVING LOOMI
`
`SUMMARY OF THE INVENTION
`
`The present invention relates to adjustable weaving looms
`and has particular relation to a simply constructed reliably
`operable weaving loom providing positive means of intercon-
`necting adjacent loom sections.
`Another purpose is an adjustable -weaving loom which may
`be made out of hollow plastic sections.
`Another purpose is a weaving loom of the type described in
`which each loom section has a projection and a plurality of
`spaced openings for use in assembling the loom sections into
`variably sized and shaped weaving looms.
`Another purpose is an adjustable weaving loom of the type
`described which provides for positive interconnection of loom
`sections.

`drawings and claims.
`
`two sections. A square cross section accomplishes this pur-
`pose, as does a rectangular cross section. Other cross-sec-
`tional configurations having straight sides are also useful.
`Again, what is_ important is to provide a cross section such that
`the loom sections cannot be rotated relative to each other, as
`this would be a serious drawback during an actual weaving
`operation.
`
`As illustrated particularly in FIG. 4, there are a plurality of
`openings 24 along the sides of each loom section. Thus, almost
`any size and shape of loom may be made out of the loom sec-
`tions. An endless variety of sizes and shapes is possible with
`loom sections in which there are openings along both sides
`and at the ends. Normally, there will only be a single projec-
`tion on each loom section, although in some applications it
`may be desirable to have several projections.
`FIG. 1 illustrates one possible use of the loom sections 10.
`There is a single section across the top and bottom, illustrated
`at 28 and 30. There are a pair of loom sections 32 and 34
`along the right side and a second pair of loom sections 36 and
`38 along the left side. The top of loom section 32 has a projec-
`tion which is inserted into the side of loom section 28. The left
`end of loom section 28 has a projection which is inserted into
`the side of loom section 36. In like manner, the remaining
`loom sections are fastened together.
`In a particularly useful weaving operation, a yarn 40 is first
`tied on a knob 42. The yarn is then laid back and forth across
`the loom, skipping a knob at each side=. The opposite end of
`the yarn 40 is finally tied at the lower end of the loom on knob
`44. The second layer of yarn 48 may begin at knob 46 and
`runs transversely to the first layer, with the end of the second
`layer being tied to knob 50. In like manner, a third layer of
`yarn runs transversely to the second layer beginning at knob
`52, with the yarn 53 again being run back and forth over the
`knobs. In this instance the yarn runs about the knobs which
`were skipped on the first layer of yarn. The yarn 53 is tied on
`knob 54 which is just above knob 44. Lastly, single strands of
`yarn may be interwoven, with such single strands being paral-
`lel to the second layer and being tied at the bottom, as on
`knobs 56, 58, 60, 62 and 64. The upper ends of the single
`layers ofyarn may be loose.
`The above illustration discloses a highly advantageous
`weaving method, however, obviously the invention should not
`be limited to any particular fabric or any particular manner of
`making a fabric.

`BRIEF DESCRIPTION OF THE DRAWINGS
`
`The invention is illustrated diagrammatically in the follow-
`ing drawings wherein:
`FIG. 1 is a top plan view of an adjustable weaving loom as-
`sembled into one configuration,
`FIG. 2 is an enlarged partial top plan view illustrating the
`means for attaching loom sections together,
`FIG. 3 is an end view ofa loom section, and
`FIG. 4 is a partial side view ofa loom section.
`
`DESCRIPTION OF THE PREFERRED EMBODIMENT
`
`The present invention relates to an adjustable weaving loom
`of the type which may be used to weave sections of fabric. The
`fabric may be used, for example, in garments, bedspreads, etc.
`Yarn may be utilized on the weaving loom in a number of dif-
`ferent ways to provide a particular weave, pattern or fabric.
`However, one particular weaving method has been found to
`be highly advantageous. Of importance is the actual construc-
`tion of the loom and the manner in which it is adjustable to
`form various sizes and shapes offabric sections.
`Turning first to FIGS. 2, 3 and 4, a loom section is indicated
`at 10 and may have a hollow interior I2 and a plurality of
`generally equally spaced upstanding knobs or the like 14, illus-
`trated in detail in FIG. 4. As is conventional in weaving looms,
`the knobs 14 may have an enlarged head 16 sitting on a post
`18. Although the knobs are described as generally equally
`spaced, obviously they may be otherwise for particular weav-
`ing operations. Each loom section may be molded from
`plastic, although this is only one example of many possible
`materials.
`
`The loom section 10 may include a projection 20 at one
`end. A bead 22 extends circumferentially about the projec-
`tion. Each of the loom sections 10 may include a plurality of
`openings 24 which extend into or are in communication with
`the hollow interior 12. Note that the space between the bead
`22 and the end surface 26 is generally the same as the wall
`thickness of the loom section. Thus the head will pass through
`the opening 24 and will be positioned in the hollow area 12
`when the projection 20 is fully inserted into a mating opening
`24. The bead will firmly hold the loom sections together and
`will prevent accidental withdrawal. If the loom sections are
`formed of a plastic which is distortable and/or compressible,
`the loom sections can be snapped together, easily withdrawn,
`but yet cannot he accidentally separated during use of the
`loom.
`
`As illustrated, the projections 20 and the openings 24 are
`generally square in cross section. This is advantageous, but not
`essential to the invention. What is important is that the loom
`sections be capable of being snapped together so that after
`they are joined, there can be no relative rotation between the
`
`1. In an adjustable weaving loom, a plurality of hollow loom
`sections, each loom section having a top surface with a plurali-
`ty ofspaced upstanding knobs, and
`cooperating joint means on said loom sections for use in
`removably attaching said loom sections together to form
`a closed weaving loom including a projection and opening
`on each loom section arranged to cooperate with projec-
`tions and openings on other loom sections, the projection
`and opening on each loom section each having a plurality
`ofgenerally straight sides, with each projection and open-
`ing having generally the same cross section to prevent
`relative rotation between loom sections,
`a circum-
`ferentially extending bead on each projection spaced
`from the end of the projection and spaced from the loom
`section a distance generally equal to that of the wall
`thickness of the hollow loom sections such that the pro-
`jections will be held within their corresponding openings.
`2. The structure of claim 1 further characterized in that
`each projection and opening are generally square in cross sec-
`tion.
`
`3. The structure of claim 1 further characterized in that
`each loom section includes one projection and a plurality of
`openings, with the projection being generally at one end of the
`loom section.
