s Claims. (Cl. zs-ss) The present invention relates 'to anadjustableeyeboard to be used in conjunction with a slashing, warping,or other machine which will allow foror require the regulation of the width of the :Warp passing therethrough.

Normally when passing laments,threads, 'yarn or Ithe like, hereinafter designated as threads, from creels or other supply sources through any of 'the machines previously mentioned, the threads, in order'to form a particular width warp, pass through an eyeboard containing holes positioned in substantially vertical rows with the horizontal distance between the outermost holes defining the width of the warp desired. Each vtime thata modification is desired either in the width ofthe warp with `the number of threads remaining the same or in the number of threads with the width remaining the same, the operator is required to stop the machine, remove all of the threads being passed through the eyeboard, replace the eyeboard with a dilerent one having the desired number of equally spaced holes for the desired width of warp, thread the new eyeboard and again put the machine into operation. The steps of replacing and threading-thefeyeboard have resulted in a considerable loss in operating time for the machine. In view of this loss of operating time the eyeboard of the present invention has been developed to substantially minimize the time required by the operator to obtain the above referred to modifications.

Broadly, this invention provides an adjustable eyeboard composed of a plurality of sections which are movable to and from each other contiguously in the same plane. More particularly, this invention provides an adjustable eyeboard comprising a frame having upper and lower channels therein, a plurality of sections having holes therein slidably mounted in the channels, lost motion links connecting the sections and a turn buckle arrangement operatively connected to the sections to move them to and from each other.

It is therefore an object of this invention to provide a novel adjustable eyeboard which will allow for the regulation of the spacing between the threads passing therethrough and thereby the regulation of the width of the warp.

Other objects and advantages of this invention will become apparent from the following detailed description when considered in conjunction with the accompanying drawings, wherein:

Figure l is a view in elevation of the eyeboard of this invention; and

Figure 2 is a sectional view taken along line 2-2 of Figure 1.

Referring to the drawings and more particularly to Figure 1, the numeral indicates an eyeboard composed of two end sections 11 and 12 and a plurality of intermediate sections 13. Each of said sections has holes 14 therein through which threads pass when being conveyed from the creels to the slashing machine. The holes 14 are so arranged in the eyeboard that they form a plurality of parallel rows departing slightly from the vertical which ICC allow for more equally spaced threads vper unit Width of the warp.

End sections 11 and 12 and intermediate sections r'13 have top and bottom parallel sides 15 and 1'6, respectively. Intermediate sections 13 also have parallel sides 17 and 18 which are parallel to therows of holes passing through the intermediate sections and form an oblique Withthe top and bottom parallel sides 15 and '16, respectively. End sections 11 and 12 each have-a side 19 and -20, respectively, which are parallel to the rows of holes in'each section and the oblique sides 17 and 18 of the intermediate sections. Positioned at the top and bottom of sections 11, 12 and 13 are lost motion links 21 which interconnect the sections and define the maximum spacing between the sections.

Enclosing sections 11, 12 and 13 is a frame 22. Frame 22 is composed of end members 23 v'and top and b'otto'm members v24 and 25, respectively. Bottom membe'r 25 is formed of three laminated plates V2'6, 27 and 28 and compression plates 29 and 30. Plates 26 and 28 (as shown in Figure 2) are of greater width than plate 27 so that upon being assembled they dene a channel in the bottom member 25 within which the lower portions of sections 11, 12, and 13 may slide. The -top frame member 24 is formed of laminated

plates

32 and 33, vanged plates 34 and 35, and

compression plates

36 and 37. As shown in Figure 2, iianged plates 34 and 35 are much wider than laminated

plates

32 and 33 so that upon being assembled they form a channel within which the lost motion links `21 and top portions of sections 11, 12land 13 may slide. v l

yAgain referring to Figure l, the means for'movi'n'g the sections to and from each other contiguously include

sleeve members

38 and 39 attached to the end-sections 11 and 12, respectively. Passing through

sleeves

38 and 39 is ashaft 40'having two'thre'aded portions thereon. Shaft 40 passes through each of the sleeves in a threaded relationship so that one threaded portion passes through the sleeve of section 11 while the other portion passes through the sleeves of section 12. The threaded portions of shaft 40 are oppositely threaded so that depending upon the direction of rotation of the shaft the end-sections 11 and 12 will move either toward or away from each other. Supporting shaft 40 are end members 23 and support 41. Preventing longitudinal movement of shaft 40 in the frame 20 are thrust shoulders 42 and 43 on each end of the shaft formed from a reduction in the diameter of shaft 40. Attached to the portion of shaft 40 extending beyond the frame members 23 by a. set screw is crank 44 which upon being rotated results in the expansion or contraction of the eyeboard.

With the parts constructed and arranged substantially as hereinbefore described, the operation, briey stated, is as follows:

As shown in Figure 1 the eyeboard is in a contracted position but rotation of the crank will first move the end sections away from each other followed consecutively by the outermost intermediate sections until the lost motion is taken up by the links whereupon the eyeboard is in its expanded position. Rotation of the crank in the opposite direction will accordingly move the sections together.

By this invention operators without exchanging eyeboards may now change the width of the warp and the number of threads going to make up said warp in a minimum amount of time and with a minimum amount of eiort.
