6 Claims.

My invention relates to toy looms or weaving frames, and one of its objects is a weaving toy that can be used in various manners.

Other objects are a loom adapted for interweaving broad yarns or bands and for interweaving yarns of different widths, to provide the two opposite broad sides or planes of a weaving frame with projections or teeth for holding yarn, to adapt the teeth of one of these sides for yarn of a width diiferent from the width of yarn for which the teeth of the other side are adapted, thereby to adapt the loom for optional use in two reverse positions and for diiferent yarns, to use, in either position, the teeth of the upper side for holding loops of yarn, and to use simultaneously the lower teeth for affixing ends of this yarn, and thereby to provide two-sets of teeth which co-operate in holding yarn of any of different widths.

Further objects are a toy loom that is inexpensive, that can be easily and quickly manufactured, that strongly resists the stress exerted by yarn spanned across the loom, that holds loops of yarn safely while allowing easy detachment of these loops, to attain these results by suitably shaping the loom from thin metal sheets, each 'of the four lateral sides of the loom forming a channel of U-shaped cross-section whereby these sides are rigid, and to form teeth by cutting out recesses along the longitudinal edges of the metal sheet whereby these teeth form integral and resilient extensions of the rigid U-shaped part.

'Still other objects are to facilitate the weaving of particular patterns according to given prescriptions or formulas, and to provide the loom with indicia for individual teeth whereby that spot can be easily identified and located where a different yarn or a diiferent color has to start;

Still further objects are to provide a set of parts which can be easily and accurately assembled into a loom, which can be easily separated for convenient storage or shipment, and which can be assembled in various manners so that frames may be formed surrounding areas of different sizes and of square or more or less oblong shapes, and thereby to facilitate the weaving of differently large or difierently shaped pieces. I

Still other objects and advantages will appear from the following description of an exemplifying embodiment of my invention, from the appended claims and from the accompanying drawing in which:

Fig. 1 shows a side view of a separable part of an illustrative embodiment of my invention, a medium part of this part being omitted.

Fig. 2 shows a cross-section taken along the line 2--2 in Fig. 1.

Fig. 3 shows a cross-section of the lower end of Fig. 1, taken along the line 3-3 in Fig. 1, and shows a correspondingly taken cross-section of an end of another similar part connected to the part shown in Fig. 1.

Fig. 4 shows a cross-section of an end of another separable part of the same embodiment which part is a modification of the part shown in Fig. 1, this cross-section being taken along a line corresponding to line 33 in Fig. 1.

Fig. 5 shows a top view of a broken off corner of an assemblage of the same embodiment, the loom holding warps of yarn.

Fig. 6 shows a top view of another broken oil corner of the same embodiment, the loom holding warps and wefts. 1

Figs. '7 to 10 show top views of four difierent assemblages of the separable parts constituting the illustrative embodiment, represented on a smaller scale than Figs. 1 to 6, some small details being omitted.

Referring to the drawings, numeral l indicates an elongated member made of sheet metal by stamping a metal sheet and by bending the same along longitudinal lines sothat the median part of the sheet is formed into ledge 4 of substantially U-shaped cross-section and that marginal areas 5 and 6 of the sheet extend from the mouth rims of the U-shaped channel outwardly in opposite directions which are substantially perpendicular to the legs of the U or to the side walls 28 of the channel. The margins 5 and 6 have cut out recesses I and 8 whereby the sheet material remaining beside these recesses forms rows of projections or teeth 9 and II. The recesses T of the margin 5 are broader than the recesses 8 of the margin 6 whereby the teeth 9 of one row are more spaced than the teeth ll Of the opposite row. The outer ends I2 and I3 of the teeth may be slightl bent to. that side which is the upper side in Fig. 2.

The teeth are relatively broad and are resilient in that direction in which their ends are bent because each tooth is formed by a thin fiat layer of sheet metal. The ledge 4 is strong and rigid due to the U-shape of its cross-section. The recesses between the teeth are preferably even broader than the teeth. One tooth of each row may be positioned at the end of the ledge while the other end of the ledge is as far from the nearest tooth as one recess.

A metal strip [4 has a width fitting the width from the ends of the respective ledges.

of the inner channel of the ledge 4. The strip I4 is bent rectangularly whereby the strip is formed into a piece having two rectangularly connected arms I and I6. The arm I5 is permanently affixed to the ledge 4 in a position where this arm extends into the channel of the ledge. For example, the central strip of the ledge 4 may have a fiat extension H of the same width as the channel, and the arm I5 may be connected to the ledge by rivets I8 passing through this extension and through the main portion 0f the ledge. The other arm I8 is provided with a bore I9 for a purpose that will be described later.

A member 2| is identical to the member I, except that the member 2i has no extension I1 and that a different piece 22 is aflixed to the member 2I instead of the piece I4. The member 2I comprises a ledge and two rows of teeth identical to the ledge and teeth of the member I. The ledges of both members are provided with a plurality of bores 23 distributed along the respective ledge and passing through the ground wall 27 of its channel. The bores 23 are preferably arranged at equal intervals nd have equal diameters identical to the diameter of the bore If].

The piece 22 is formed by a straight metal strip of a width fitting the width of the ledge channels. Aportion of the piece 22 reaches into the channel .of the member 2I and is permanently aflixed thereto, for example, by rivets 29. The remaining portion of this piece has one or more bores 24 having diameters equal to those of the bores 23.

For the assemblage of the loom, a set of parts is used which comprises four members I, each provided with an angular piece I4. These members are united by connecting the arm I6- of each member to the ledge of another member in a position where the arm I6 is partly or totally positioned in the channel of this other ledge. Preferably, these parts are connected by inserting a heatled bolt through the bore I9 and through one of the bores 23 of the other member. The bolts 25 may be provided with screw threads engaged by nuts 26 whereby the parts are more securely connected. The angular pieces l4 fittingly inserted in the channels of the parts secure an accurately even or horizontal extension f the rectangular frame formed by the thus united members.

By selecting certain bores 23 or other bores 23 for insertion of the bolts 25, different configurations may be formed by the members I. For example all corners of the frame may be connected in the manner shown in Fig. 3. In this case, the

frame surrounds a square area of a side length equal to that of a ledge 4, and each bolt 25 passes through that bore of the connected ledge which is nearest to the end of this ledge.

Fig. '7 exemplifies an assemblage where all bolts are inserted in bores 23 which are equally farther The surrounded area is a smaller square.

Fig. 8 exemplifies an assemblage Where one pair of opposite bolts is inserted in bores 23 near- The resulting frame surrounds an oblon According to the number of bores 23 Members 2!, for example, two of such members,

may be additionally used for the assemblage of a loom. These latter members serve as lengthening extensions of members I, each member 2| being connected to that end of a member I which is opposite to the angular piece I4 afiixed to the later member. The members I and 2| are connected by inserting the bored portion of the piece 22 into the channel of the member I in a position where the ends of the ledges of the two members abut each other. In this position, one or two bores 24 of the piece 22 are co-axial with one or two bores 23 of the member I. Then bolts of the type 25 are inserted in the coaxial bores and may be secured by nuts 26 in the same manner as the bolts 25 passing through the holes IQ of the pieces Additional use of members 2I permits the assemblage of larger looms. Also in this case, different configurations are possible which are exemplified by Figs. 9 and 10.

In assembled position, the open sides of the channels of all ledges face the area surrounded by the ledges. The lateral walls 28 of all ledges form two frame-shaped plane surfaces of which either may be placed on top while the other extends parallel to the top surface at the lower side. The rows of teeth 9 extend perpendicularly to these frame surfaces to one side while the teeth I I extend to the opposite side. The upper side of the frame is used for'holding yarn loops during the weaving operation. The 10cm can be simply adapted for different yarns by reversing the loom and thereby reversing the position of the teeth 9 and I I.

The ledges are provided with indicia for the teeth. For example, numerals are printed or otherwise shown on the outer sides of the walls 28. Each of these numerals is in line and near to one of the teeth whereby the numeral identifies this tooth. Preferably, these numerals are arranged in series starting from the ends of the ledges.

After its assemblage, the loom may be used in the following manner:

Preferably a relatively broad band of yarn of resiliently stretchable material is used, for example, of plastic material. The end of a suitable length of this yarn is tied or knotted to one of the lower teeth of the loom, for example to a tooth near one of the loom corners. This yarn is then drawn from the tied end over the outer wall of the adjacent ledge to the upper side and is spanned across the loom as shown at 3| in Fig. 5. After being placed around the first tooth of the opposite ledge, the yarn is drawn back, placed around a tooth of the first ledge and so on, the yarn following a snake-like path proceeding from tooth to subsequent tooth as shown in Fig. 5 whereby warps 32 are spanned across the loom. Then, an end of a similar yarn is similarly tied to a lower tooth near the corner end of a ledge that crosses the ledges between which the warps extend. This latter yarn is drawn to the upper surface of the loom as shown at 33 in Fig. 6 and is spanned to the opposite side while the yarn is passed alternately over and under the warps 32. A suitable needle of known shape may be used for drawing the yarn through the gaps between the warps. At the opposite ledge, the yarn is placed around a tooth whereupon the yarn is spanned back to the next tooth of the ledge from which it started, the yarn again alternately passing at upper and lower sides of the warps, and so on, in a path similarly snake-like like the path of the warps, but crossing the path of the latter. Thereby wefts 35 are formed which are interlaced or interwoven with the warps 32. The mutual pressure between the warps and the wefts forces the same into horizontally flat positions.

Preferably the yarns are so broad that, in this 7 of the teeth shown in Fig. 2, the loops are safelyv held by the teeth during the weaving operation.

But, when the operation is finished, the loops can I be easily removed from the teeth which under slight pressure, resiliently bend inwardly and re-- lease the loops. 7

It is important for a smooth and accurate result, that the yarns are spanned across the loom under some tension. Ihe strength and stifiness of the channelled ledges allows exertion of suilicient tension without distortion of the frame.

I desire it understood that my invention is not confinedto the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways without departing from the spirit of my invention as it is obvious that the particular embodiment shown and described is only one of the many that may be employed to attain the objects of m invention.
