corporation of Delaware Application September 9, 1948, Serial No. 48,404

The present invention relates to a whip roll device for a loom and more particularly to a whip roll mounting or supporting structure.

In a conventional loom, there is provided a whip roll over which the warp passes from its beam to the harness. The whip roll serves as a guide to direct the warp sheet substantially horizontally from the warp beam towards the harness and to tension said warp sheet. The whip roll may be correlated with the let-off motion or may simply serve as a warp guiding and tensioning device.

One object of the present invention is to provide a new and improved whip roll supporting structure, which afiords resilient, or fixed, mounting of the whip roll in operative position, which is easily adjustable to permit adjustments in the position of the whip roll with respect to the cloth fell in accordance with the different weaving conditions desired and which is self-aligning to assure proper alignment of the whip roll in spite of inaccuracies and to permit the positions of the ends of the whip roll to be adjusted separately.

Various other objects will be apparent from the following particular description and from an inspection of the accompanying drawings, in

- which:

Fig. 1 is a rear fragmentary view of the loom showing the whip roll device and its supporting structure embodying the present invention;

Fig. 2 is a side elevation of the supporting structure for one end of the whip roll; and

Fig. 3 is a section of the whip roll supporting structure taken approximately along the lines 3.3 of Fig. 2.

The drawings show the improved whip roll device and part of a loom to which the same may be applied. The loom is shown comprising a right loomside I and a left loomside ll interconnected by cross-members such as girts and each comprising an inner web I2 and an outer web l3 suitably cross-braced. The loomsides mount bearings M for rotatably supporting a warp beam l5 containing the warp supply from which the warp sheet is taken. The warp sheet extends upwardly and forwardly about a whip roll it and then forwardly towards the front of the loom into the field of operation of the shedding mechanism.

The whip roll l6 of the present invention is not of the type which is correlated with the op eration of the let-ofi motion as in the case of a Bartlett let-off motion, but desirably is of the type which has no connection with the let-ofi motion and serves merely as a Warp guiding and tensioning device.

5 Claims. (Cl. 139-114) In the specific form of the invention shown, the whi roll l6 comprises a, steel tube 20 closed at its ends by plugs 2| press-fitted or otherwise secured therein and each having an axial hole into which is fitted a gudgeon or journal 22. These gudgeons are secured to respective plugs 2| by pinning or the like and are journalled in the bearings 23 of whip roll supports 24 at the opposite ends of the whip roll it.

Each of the whip roll supports 24 comprises a rod or shank 25 having at one end a head in the form of an eye defining the bearing 23. This bearing comprises a bearing ball 26 retained in a suitable socket or race structure 21 for free universal movement therein and having a circular hole 28 through the center to receive the gudgeons or journals 22 with a press-fit. The udgeons 22 thereby rotate with the respective bearing balls 26, which are free to move universally in the socket or race structures 21.

Each of the whi roll support rods 25 passes through a, sleeve 35 with a free snug slide fit and is formed near one end with an axially facing shoulder 36 at the base of the bearing 23, for the purpose to be described, and at its other end projects beyond the corresponding end of said sleeve and is threaded to receive a limiting nut 31 and a locking nut 38. A coil spring 40 encircles the rod 25 beyond the sleeve 35 and is seated at one end against said sleeve and bears at the other end against the shoulder 36 to urge the rod axially in one direction along said sleeve and against the limiting action of the nut 3']. The nut 31 can also be set tight against sleeve 35 thereby eliminating the action of the spring 40 and providing a solid support for the whip roll [6. A tube 4| embracing one end of the sleeve 35 and secured thereto, as for example by welding, houses the coil spring 40 and limits movement of the whip roll support rod 25 in an opposite direction. I

The sleeve 35 is supported for angular and lengthwise adjustments. To that end, there is secured to the outer face of each inner loomside web 12 a bracket 45 serving as a swivel support for a clamp 46 embracing the corresponding sleeve 35. The bracket 45, as shown, is connected to the loomside web,l2 by cap screws 4'! of the socket type and has a circular recess 48 on the side thereof nearest the loomside web l2 and a circular hole 50 of smaller diameter extending from said recess. The clamp 46 has a circular flange 5| at one endextending inthe bracket recess 48 with a swivel or-rotative fit, a cylindrical section 52 of reduced diameter passing through the bracket hole 50 with a bearing or swivel fit, and a split clamping part 53 embracing the sleeve 35.

The sections of the clamp 46 on opposite sides of its split are releasably drawn towards each other and about the sleeve 35 by means of screws 54 shown of the cap socket type.

The bracket 55 is of the split clamping type and has the sections on opposite sides of its split releasably drawn towards each other and about the clamp flange i and the cylindrical clamp section 52 by a bolt 56 shown of the socketed head type.

To afford visible indications of the adjusted angular position of the whip roll supports 2 the exposed face of each bracket 45 has a series of indicia 60 arranged around the edge of its hole 50 along a quadrant arc and the exposed face of the clamp section 52 has a radial pointer Bl marked thereon for indicative cooperation with. said indicia. The indicia 6n and the pointer 6| are desirably so arranged, that when the rod 25 and embracing sleeve 35 extend vertically, said pointer will be directed to one end of the indicia scale and when said rod and sleeve extend horizontally, said pointer will be directed to the other end of the indicia scale. The whip roll support 24 will thereby have a range of adjustment. of 90 from vertical to horizontal.

To aiTord visible indications of the adjusted lengthwise position of the whip roll supports it, the sleeve 35 has arranged therealong a series of indicia 62 indicativel-y cooperating with the ad joining edge of the split clamping part 53 of the clamp 46.

For adjusting the postion of the whip roll !6 the clamping bolt 56 for each support 24 is loosened to permit the clamp 46 to be rotated to the desired angular extent and the whip roll it to be located thereby in the approximate desired. position with respect to the cloth fell. The elevation of the whip roll 16 can be adjusted approximately by loosening the studs or screws 54 and. moving the sleeve 35 lengthwise in the clamp 45. By properly maneuvering the two adjusting devices .for angular and lengthwise movements of the whip roll supports 24, the bearings 23 can be accurately located in the desired positions, in accordance with the required weaving conditions. The bolt 56 and screws 54 can then be tightened in the adjusted position of the whip roll supports 24.

The bearing .23 in .each whip roll support 2 being of the universal type, said supports can be adjusted one at a time. Furthermore, this hearing feature permits proper self-alignment of the bearings 23, to compensate for inaccuracies in adjustments or in construction.

While the invention has been described with particular reference .to a specific embodiment, it is to be understood that it is not to be limited thereto but is to be construed broadly and restricted solely by the scope of the appended claims.
