8 Claims. (Cl. 28-15) This invention relates to what are generally referred to as weaving frames. More particularly, the invention deals with a frame structure composed of four identical rail parts with interengaging means at end portions of said parts for adjustably clamping one end of one part with the opposed end of another part in adjustment of the frame to predetermined dimensions.

Still more particularly, the invention deals with a frame, wherein the separate parts of each of the rails are formed from die castings, mouldings and extruded products which can be quickly and easily assembled in forming the rail assemblage.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. l is a perspective view of one corner portion of a Weaving frame made according to my invention, with parts of the construction broken away.

Fig. 2 is a broken sectional and plan view showing two corner portions of a frame and illustrating parts of three rails of a frame.

Fig. 3 is an edge view of one corner portion of a frame made according to my invention; and

Fig. 4 is a view looking in the direction of the arrow 4 of Fig. 3, omitting the winged screw and also omitting parts of the background showing.

My invention deals with weaving frames composed of four adjustably coupled members to facilitate formation of rectangular frames of different areas, depending upon the weaving operation to be performed. In order to simplify the showing, portions of three of the members employed are indicated in Fig. 2 of the drawing. It will be apparent, however, that the fourth member is identical with the three members which are partially shown. As all of the members are of identical construction, the brief description of one member will be applicable to all.

In Fig. 2 of the drawing, 10 represents a plan view of one end portion of a frame member. of a similar member, coupled with the end portion of the member 14 10" represents a portion of a third member, similar to the member 10, and no showing is made of the fourth member. Where identical parts of the members are shown in the views, the reference numerals will be primed consistent with the priming of said members.

Each member comprises an elongated and preferably extruded rail 11 substantially of L-shaped cross-sectional form, note Fig. 3. The rail 11 is defined by angularly disposed wall portions 12 and 13, the free edge of the wall portion 13 terminating in an angularly extending flange 14. The upper surface of the wall 12 has an elongated dovetailed channel or recess 15 extending the full length of said wall or, in other words, opening through both ends of the rail.

A die cast bracket 16 is fixed to one end of the rail 11, the bracket comprising a substantially V or yoke-shaped 10 indicates part States Patent channel portion defined by walls 17, 18 and 19, the walls 17 and 18 being disposed at right angles to each other; whereas, the wall 19 flares upwardly and outwardly a suflicient degree to freely receive the rail 11, as clearly noted in Fig. 3 of the drawing.

Extending outwardly from the wall 19 is a cylindrical portion 20 which is internally threaded to receive the winged set or clamp screw 21, the screw 21 having a winged fingerpiece end portion 22. Extending from the wall 17, adjacent one edge thereof and at right angles to said wall, is a plate portion 23 having integral rivet portions 24 on the surface thereof. The rivet portions 24 are adapted to pass through corresponding apertures formed in the end 25 of the rail or in the wall 13 of said end and to be headed over, as seen at 26, in securely fixing the bracket 16 to the end 25 of the rail. For purposes of description, the end 25 of the rail can be defined as the bracket end of the rail; whereas the opposed end can be regarded as the free end.

The bracket 16 also includes a reinforcing rib 27 which is in alinement with the plate 23 and extends beneath the wall 18 and onto the cylindrical portion 29, as clearly seen in Figs. 3 and 4 of the drawing. The cylindrical portion 20 also includes an upwardly contracted marker or indicator 23 to gauge adjustment of the members one with respect to the other in regulating the size of the frame to be formed.

The screw 21 can be formed as a die cast product, thus simplifying the cost of production of the resulting frame. However, other types of screws can be used, if desired. In considering Figs. 1 and 3 of the drawing, it will be apparent that the screw 21 operates to engage the wall 13 of the rail 11' in securely clamping the rail 11' in the yoke-shaped portion of the bracket 16 in adjusting the size of the resulting frame.

I also employ pin strips 29 which constitute part of each of the rails and, here again, the pin strips are all of similar construction, thus making each rail identical in construction with the companion rails. The strip 29 is preferably formed as a moulded plastic product and comprises a baseplate portion 30 of dovetailed cross-sectional form to fit snugly in the dovetailed recess or channel 15 of the rail 11, as is clearly illustrated in Fig. 3 of the drawing. The strip has, spaced along the upper surface thereof and protruding above said surface, a predetermined common spacing of pin members 31, the pin members in the construction shown being in the form of a relatively thin but wide members, as clearly illustrated in Figs. 1, 2 and 3 of the drawing, and these members being preferably disposed adjacent the edge portion 32 of the baseplate 30 and the pin members taper upwardly, in the manner clearly noted in Figs. 2 and 3 of the drawing. The pin members 31 have outer edges 33 and inner edges 34.

Considering Fig. 3, it will be apparent that the outer edge 33' of the pin members 31' are disposed at right angles to or perpendicularly to the baseplate 30'; whereas the inner edge 34 is tapered upwardly and inwardly so that the upper ends of the pin members are of less width than the lower end portions thereof. This construction facilitates attachment and detachment of the yarns from the frame in the use thereof. Spaced along the upper surface of the baseplate 39 are numerals, parts of which are seen at 35, the numerals 1'7 and 18 being diagrammatically shown in Fig. l of the drawing; whereas the numeral 1 is indicated at 35 in Fig. 2 of the drawing. In the construction shown, these numerals would indicate substantially eighteen inches of length in the pin strips 29, 29' employed.

At widely spaced intervals along the outer edges of the baseplate are key notches. To illustrate at least one of these notches, the bevelled edge 35' of the baseplate 30' has a key notch 37', into which part of the wall portion 12 is pressed in definitely keying the pin strip 29 in proper position on the rail 11. The notch 37' is indicated in Fig. 1 of the drawing, but several of these notches are employed on the pin strip 29 and on all of the pin strips employed.

It will be apparent from a consideration of Fig. 2 of the drawing that the free end of each rail is adjustable through the bracket end of an associated rail and can be clamped with the associated rail by the set or clamp screw. In Fig. 2 of the drawing, the screw 21 is shown engaging the rail 11 and the screw 21' is shown engaging the rail 11". In shipment and storage of the frame, it will be apparent that the rails can all be disassembled and packed or stored in a relatively compact elongated package.

For purposes of description, the wall 12 of the rail 11 can be regarded as the top wall, the wall 13 as the inner wall and, correspondingly, the wall 17 of the bracket 16 can be regarded as a back wall, the wall 18 as a bottom wall and the wall 19 as a front wall. In this connection, it is to be noted that the baseplate 30 of the pin strip 29 has its upper surface flush with the upper surface of the top wall 12 of the rail. The pins or pin members 31, accordingly, may be said to be adjacent the inner or rear edge of the strip; whereas, the numerals 35 are disposed at the outer edge thereof. While reference here is made to the parts only of the member 10, the same is, of course, applicable to the other members of the frame employed, as for example, the members and 10".
