a l 'Ihisinvention relates to a novel one piece Warp clamp for clamping warp to a whip roller for holdingthe warp straight while it is brushed into a portable tying machine and while it is being tied to insure that the warp will be tied straight on a loom so that it will run satisfactorily.

More particularly, it is an aim of the present invention to provide a one piece warp clamp-of extreme simple construction which will prevent twisted warp when the warp is subsequently 4 Claims. (01. 28-42) I corresponding sides or faces I6 of which are preferably disposed at a right angle to one another and merge at their outer edges with the opposite sides I2 and I3. 1

A relatively thick strip of yieldable material I'I, preferably sponge rubber, is suitably secured to each of the groove faces I6 near the outer edge. thereof, and said sponge rubber strips I? pulled or run over the loom from a warp beam.

Various other objects and advantages of the invention will hereinafter become more fully apparent from thefollowing description of the drawing, illustrating a preferred embodiment thereof, and wherein:

Figurel is an end elevational view showing the one piece warp clamp secured to a whip roller and illustrating the location of the whip roller with respect to a warp beam;

Figure 2 is a fragmentary side elevational View of the whip roller with the clamp applied thereto;

Figure 3 is an enlarged cross sectional view taken substantially along a plane as indicated by the line 3-3 of Figure 2, and

Figure 4 is a fragmentary plan view looking toward the upper side of an end of the warp clamp. I

Referring more specifically to the drawing, for the purpose of illustrating one application and use of the one piece warp clamp, designated generally 5 and comprising the invention, an end of a warp beam is illustrated in Figure land designated 6 and a whip roller 1 is shown disposed above the warp beam 6 while a portion of a loom rail 8 is illustrated beneath the warp beam. These parts are of conventional construction and constitute no part of the present invention, and the warp beam '6 and roller I may be journalled in any suitable supporting structure, not shown.

The warp clamp 5 includes an elongated body portion 9 which may be formed of any suitable material and which may be in one piece or may be formed from three abutting pieces, as illustrated, including arr-intermediate strip I0 and corresponding side strips II which are secured in any suitable manner in abutting engagement to the opposite sides of the intermediate strip extends from end-to-end thereof and the two extend from end-to-end of'th'e groove-I5 and erect a width substantially less than the width of the faces 16 so that each strip "I It has an'inner edge spaced a substantial distance from the bed of the groove I5, as best illustrated in Figure 3.

A pair of plates I8 is attached against the side I2 of the body 9, one adjacent each end thereof, bysuitable fastenings I9 and each plate I8 is provided at one end thereof with an eye 20 to" each of which eyes is'fastene-d an end-of a chain or other flexible member 2I. The chains z'l are attached at their opposite, free ends to eyes 22 forming the heads of bolts 23. A wing 'nut 23a is threaded on each of the twobolts 23. A pair of rigid metal plates or strap members 24 are disposed against the outer side I4 of the body member 9 and transversely thereof and in alignment with the plates I8. The. strap members 24 are secured by suitable fastenings 25 to the elements II of the body member'll and each strap member 24 has a bifurcated end 26 whichprojects outwardly from the side'l'3. v

One preferred application and use of'the one piece or ;unitary Warp clamp has been illustrated in the-drawing. Assuming that a new or filled warp beam ,6'has been applied in a position as illustrated in Figure 1 beneath the'whip roller 7, in a conventional manner forming no part of l the present invention, the warp 21 is extended ,upwardly from the warp beam 6 in a counter clockwise direction over the whip roller '2, illustrated in Figures land 3 and is then drawn counterclockwise downwardly around the under part of thewarp beam 6 and projects from between the warp beam 6 and the loom rail 6 away from the warp beam. The end of the warp which extends outwardly between the warp beam 6 and loom rail 8 is then pulled until the warp extends straight from the Warp beam up and over the whip roller. The body member 9 of the clamp 5 is then disposed on the whip roller, as illustrated in Figures 1, 2 and 3 with the exposed outer faces of thesponge rubber strips I1 engaging against circumferentially spaced portions of the warp 21 which is trained over the whip roller 1. The clamp 5 may be made in various lengths and the body member 9 thereof is considerably longer than the width of the warp 21, as illustrated in Figure 2, so that when the body member 9 is thus applied to the warp on the upper part of the whip roller 1 the chains 2| will be disposed beyond the side edges of the warp 21. With the wing nuts 23a backed off toward the distal ends of the bolts 23, the chains are extended around the underside of the whip roller 1 in a clockwise direction as seen in Figures 1 and 3 and beyond the side edges of the warp 21 and the bolts 23 are inserted'into the slots of the bifurcated strap portions 26, through the open outer ends of said slots, each bolt 23 engaging the strap portion 26 which is disposed in transverse alignment with the chain 2! to which said bolt is connected. The wing nuts 23a are then turned in the opposite direction to draw the bolts 23 upwardly through the bifurcated strap ends 26, since the nuts 23a will bear against the upper surfaces of the furcations of the bifurcated ends 25. The nuts 2311 are thus tightened until the chains 2| are drawn tight around the under part of the whip roller 1 to thereby draw the clamp body member 9 downwardly to bring the strips ll into tight gripping engagementagainst the whip roller 1 for clamping spaced portions of the warp 21 between said strips I1 and the whip roller '1. The warp or yarn 21 while thus clamped is cut off straight across near the loom rail 8 and the cutoff endof the warp is then pulled back over the clamp 5 and the whip roller 1 is allowed to turn'clockwise from its position of Figures 1 and 3 until the clamp is disposed beneath the whip roller. The cutoff end of the warp is then brushed into a portable tying machine and tied, not shown, after which the clamp 5 is removed and the warp beam 6 turned clockwise to take up the slack. The warp is then ready to be pulled or run.

It is to be understood that the foregoin 'constitutes only one possible use of the unitary warp clamp 5 in conjunction with a portable tying machine and that it may be used in other ways in connection with the tying machine for temporarily clamping the warp to a whip roller to initially position the warp so that it extends straight off of a warp beam cover a whip roller and to effectively clamp and hold the warp iria straight condition was it has been tiedand is ready to be run. .Thus, with the use of thewarp clamp 5, the elimination of twisted warp is 'accomplished since the warp is extended straight from the warp beam and clamped to the whip roller while it is being tied straight ona loom.

Various modifications and changes are conteinplated and may obviously be resorted to, without departing from the spirit or scope of the invention as hereinafter defined by the appended claims.

I claim as my invention:
