Application April 9, 1937, Serial No. 135,997 1 Claim. (Cl. 242-124) This invention relates to Warp beams for looms and has for the primary object the provision of a inner walls of the outer annular elements 'i and device of this character wherein the various parts define between said inner and outer elements an may be easily assembled and taken apart when nular spaces to receive the cylinder with its ends necessary and the warp flanges thereof readily abuttingr the flanges i9. Tie bolts i i extend and accurately adjusted relative to each other for through the inner annular elements 6 and 5 through the cylinder for tightly securing the accommodating warps of different widths and to tension drums on the cylinder. It is to be under assure correct centering of a warp on the cylinder stood that a, tight frictional ñt is provided be of a beam. tween the flanges I0 and the outer annular ele With these and other objects in view, this in ments 7. 10 vention consists in certain novel features of con A feed shaft I2 is arranged in the cylinder end struction, combination and arrangement of parts wise of the latter and is journaled in openings to be hereinafter more fully described and formed in the tension drums and one end of the claimed. feed shaft projects beyond one of the drums and 15 For a complete understanding of my invention, is shaped to» provide wrench engaging faces I3 15 reference is to be had to the following' description so that a wrench or similar tool may be adapted and accompanying drawings, in which to the shaft for the purpose of rotating the Figure l is a side elevation illustrating a warp latter in either direction. Right and left hand beam constructed in accordance with my inven screw threads are formed on the shaft I 2 and tion. Figure 2 is a sectional view taken on the line 2_2 of Figure l. Figure 3 is a transverse sectional view taken on the line 3_3 of Figure l. Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 2. Figure 5 is an end view illustrating one end of the warp beam. Figure 6 is a fragmentary longitudinal sec tional view showing removable closure plates for the slots in the cylinder provided for the feed nuts to operate in. Figure 7 is a perspective View illustrating one of the closure plates. Figure 8 is a fragmentary plan view illustrat ing one of the slots in the cylinder of the device. Referring in detail to the drawings, the nu meral i indicates a cylinder equipped with slots 2 for the attaching of a warp on said cylinder and 40 adjustable relative to each other and on the cylinder are warp flanges 3. Said flanges 3 may be accurately adjusted towards and from each other to accommodate on the cylinder warps of different widths and act to properly center a warp on the cylinder. Mounted on the ends of the cylinder are tension drums 4 each provided with peripheral spaced flanges 5 and each in cluding inner and outer annular elements 6 and 'I. The inner annular elements B are centrally 50 apertured to receive pintles 8 employed for rotat ably supporting the beam on a loom and each has an integral collar 9 arranged in abutting engage ment with the inner annular elements E. The inner annular elements 6 are provided with pe ripheral flanges IU which frictionally engage the meshing with said threads are feed nuts i4 pro- 20 vided with extensions I5 that project through slots i6 formed in the cylinder. The extensions i5 are of tenon shape and the warp flanges are grooved to receive the extensions I5 thereby establishing a dove tail ñt between the extensions 25 and the Warp flanges. The extensions are de tachably secured on the warp flanges by stud bolts Il. Meshing with the threads of the feed shaft I2 are lock nuts I8 adapted to be turned in engagement with the feed nuts after an adjustment of the warp flanges relative to each other has been made for the purpose of securing the warp flanges against accidental movement rela tive to each other or on the cylinder. The lock nuts have wrench engaging faces se that a wrench or similar tool can grip the latter by entering the cylinder by Way of the slots I6. Pinned on the feed shaft I2 are collars I9 which engage with the tension drums to prevent end Wise movement of the feed shaft. Thus it will be seen that by rotating the feed shaft I2 in opposite directions, the warp flanges may be moved towards and from each other on the cylinder for the purpose of accommodating warps of different widths and after an adjustment has been made said warp flanges can be secured 30 35 40 45 against accidental displacement by turning the lock nuts I8 against the feed nuts I ll. Formed in the warp flanges are chambers 2t and are located opposite to the feed nuts. Slidably 50 mounted in the chambers and arcuately curved to conform to the contour of the cylinders are pressure shoes 2l forced into engagement With the cylinder by set bolts 22. Said set bolts are equipped with lock nuts 23. The pressure of the 55 2 2,187,572 disconnected from each other. The inner and outer annular members 6 and 'l are secured to gether by keys 28 held by set bolts 29. The ends of the set bolts 29 are arranged inwardly of the peripheries of the tension drums and are of the socketed type to permit a wrench to be applied thereto. Warp flanges relative to each other and it is ' What is claimed is: desired to close portions of the slots I6 lying A Warp beam comprising a cylinder having between the warp ñanges, closure plates of a slots extending longitudinally thereof, tension 10 certain size are selected for closing said portions 10 of the slots. Said closure plates when adapted drums mounted on the ends of the cylinder, a on the cylinder project into spaces provided in feed shaft rotatably supported by said drums the hub portions of the warp îlanges, as clearly and lying within the cylinder, Warp flanges shown in Figure 2. Secured to the inner wall of slidable on said cylinder, feed nuts engaging the the cylinder and projecting beyond opposite feed shaft and extending through the slots and shoes on the cylinder may be varied by the ad justment of the set bolts. Used in connection with the beam is a plu rality of closure plates of various lengths one of which is shown in Figure 7 and designated by the character 24. After the adjustment of the 15 edges of the slots are ears 25 to form seats for supporting the closure plates and each closure plate has detachably secured thereto a bridge 26 which may be brought into engagement With the inner walls of the cylinder after the positioning cr” the closure plate in the slot to cooperate with the ears 25 in preventing accidental displace ment of the closure plate. The inner annular elements ß are secured on the pintles 3 by keys 2? and engaging with said keys are set bolts 28 to prevent the pintles and annular elements from becoming accidentally secured on said Warp flanges, said Warp flanges having chambers, adjustable pressure shoes mounted in said chambers and bearing against said cylinder, ears formed on the inner face of the cylinder adjacent the slots, removable closure plates for closing portions of the slots lying be tween the Warp flanges and engaged by said ears, and retaining elements pivoted on the plates to be positioned to engage the cylinder and cooper ate With the ears in removably mounting the 25 plates on the cylinder.
