References Cited UNITED STATES PATENTS 2,351,513 6/1944 139/1 R 3 C1aims,2 Drawing Figures METHOD OF SUPPORTING MAIN GIRT BACKGROUND OF THE INVENTION In the past, textile looms for the weaving of fabrics have utilized loomsides, that is the principal frame element on each side of the loom, which were produced as single unitary elements. Normally, each loomside was produced by casting a suitable metal, most often gray iron, and then finishing the casting to provide the necessary mounting holes, finished surfaces, etc. All of the peripheral equipment necessary to the operation of the loom, such as the whip roll, warp beam, drive motors, drive shaft and so forth, were all mounted on these unitary loomsides. Additionally, the main girder of the loom had to be secured to the opposing surfaces of each of the loomsides and this assembly was frequently a tedious and expensive operation. In constructing looms of greater than normal width, expensive jigging was often required to hold the loomsides and the main girder in positions where they could be secured together.

It is a principal object of this invention to provide an improved loomside construction in which assembly of the loomside with the main girder is more easily accomplished than has been previously possible.

Another object of this invention is to provide an improved loomside which is capable of supporting the loom main girder prior to being secured thereto.

Other objects and advantages of this invention will be in part obvious and in part explained by reference to the accompanying specification and drawings, in which:

DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view, showing the main girder in phantom view illustrating the manner in which the loomsides are constructed and the manner in which the main girder is attached thereto; and

FIG. 2 is a fragmentary perspective view illustrating how the main girder is assembled with the improved loomside.

DESCRIPTION OF THE PREFERRED EMBODIMENT For a more complete understanding of the nature of this invention, reference is made to the drawings and particularly to FIG. 1. The loomside is indicated generally by the numeral and on any loom there will be two loomsides between which a main girder extends and is attached to. In FIG. 1 the main girder is indicated in phantom lines by the numeral 11. The basic part of the improved loomside is the primary loomside support section 12. Primary support section 12 has a front end 13, a back or rear end 14, an upper end 15 and a lower end 16. Together these ends 13-16 define the perimetrical limits of the primary support section. The lower end 16 performs the function of supporting the primary section on the floor or other supporting surface.

On one surface of each of the primary sections there is provided means formed integrally with the primary support which receives the loom main girder to locate the end of the girder at a preselected location with respect to the perimetrical limits of section 12. As best seen in the right hand side of FIG. 1 and in FIG. 2, there is provided means 20 which defines a shelf for vertically supporting the main girder and thereby placing it in a preselected location between upper end 15 and lower end 16. Similarly, each of the surfaces of the primary support section includes a pair of spaced apart means 21 that locate the girder with respect to the front and rear ends 13 and 14. The means 21 define shoulders 22 that positively locate the girder in the desired position for securement to primary support section 12.

In addition to the primary support section, each loomside also includes a plurality of secondary support sections 25, 26 and 27 which support loom parts required for proper functioning of a completed loom. For example, the left front quarter panel 25 might support a pick finder control while the right front quarter panel 25 might support the shipper, drive, etc. The left rear quarter panel 26 would help support the whip roll. the warp let-off and the right rear quarter panel would also help support the whip roll and the let-off as well as some of the electrical equipment. The attachment 27 would in most instances constitute the warp let-off support. It will be noted that all of the secondary support sections are removably secured to the primary support section 12 by means of removable fasteners, here shown as bolts 30, nuts 31 and lock washers 32.

The feature of having the secondary support sections removably secured to the primary section 12 is that for the first time in the history of loom construction, it is possible to alter or modify the construction, and thereby the method of operation, of a loom without replacing the entire loomside. With the construction here described, it is possible to change the pick finder control on a loom, for example, without the necessity of completely dismantling the loom and starting with completely new and different loomsides.

To produce a basic loom frame, it is necessary only to first provide the necessary primary loomside support section and the desired secondary support sections as previously described. Once these sections are attached, one to the other, the main girder can then be lowered onto the shelf 20 without any requirement for jigging or other special support equipment. In addition, the girder will of course be located between the two locating elements 21 and therefore be properly located between the front and rear ends 13 and 14. Since the shelf 20 holds the main girder, the principal part of the loom frame is at this point self-supporting and requires only that the cap screws 33 be threaded into locked position within the drilled and tapped openings in the main girder 11. Threaded fasteners other than cap screws can of course be used secured to the main girder 11 to the primary loomside support sections 12.

Although the present invention has been described in connection with preferred embodiment, it is to be understood that modifications and variations may be resorted to without departing from the spirit and scope of the invention, as those skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention and the appended claims.
