Loom ATTACHMENT.

Applicationflled August 8, 1925. Serial No. 49,052.

This invention relates to improvements in looms and has particular reference to cloth beam bearings, an object being to provide means for preventing the beam trunnions from accidentally moving in their bearings in such manner as to injure the weave of the fabric, yet permit of the cloth beam be ing readily removed and replaced. 5

With the above and other ob 'ects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary View illustrating the invention.

Figure 2 is a fragmentary elevation at right angles to Figure 1.

Figure 3 is a detail perspective View of the retaining block.

Figure t is a fragmentary sectional view looking at the inner face of one of the bearing brackets, showing a slightly different form of retaining block;

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 1O indicates a portion of the loom frame to which is attached as indicated at 11 a hearing bracket 12, one of these brackets being positioned at each end of the yarn beam 13 to receive the yarn beam trunnions 14.

The brackets 12 are provided with bearings 16 and 17 the latter being designed to support the beam 13 when the latter is re moved from the bearings 16.

The bearing brackets 12 carry arms 18 and these arms are provided with inclined faces 19 which are adapted to engage in.- clined faces 20 provided upon lugs 21, the said lugs extending laterally from retaining blocks 22. As shown in Figure 3 of the drawings these blocks have a lug 21 extending from each sideso as to adapt the block for either side of the loom frame.

By reference to Figure 1 of the drawings it will be seen that the lower edges of the blocks 22 engage the trunnions 14 and by forcing the blocks inward, the inclined faces 19 and 20 will cause the lower edge of these blocks to bind tightly upon the trunnions 14 to securely hold the trunnions in place.

An adjusting bolt 23 extends through the of a bearing notch 16 and the retaining block 22 is so positioned as to prevent accidental outward movement of the trunnion. In this form of the invention, the slot 24 is inclined with respect to the bottom edge of the block.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims 7 Having described the invention what is claimed is 1. In a yarn beam bearing for looms, a bearing bracket for supporting the beam trunnion, an arm extending from said bracket and having an inclined face extending transversely of the trunnion, a slidingly adjustable retaining block mounted upon the arm and engaging the beam trunnion, an inclined lug carried by the block and engaging the inclined face of the arm and means to hold the block in adjusted position.

2. In a yarn beam bearing for looms, a bearing bracket for supporting the beam trunnion, an arm extending from said bracket and having an inclined face extending transversely of the trunnion, an adjustable retaining block, a lug extending laterally from the block and having an inclined face to engage the inclined face of the arm to adjust the block relative to the beam trunnion and means to hold the block in adjusted position. i

3. In a yarn beam bearing for looms, bearing brackets having depressed trunnion receiving portions for relnova-bly supporting the trunnions of the beam, an adjustable block mounted upon each bracket and arranged to provide a longitudinally disposed outwardly and downwardly inclined trunnion engaging face, means carried by the brackets and extending transversely of the trunnions to mount the blocks to permit of horizontal adjustment and means included in the brackets and blocks to move the blocks vertically when said blocks are adjusted horizontally. i L;

In testimony whereof I aflix my signature.

CHARLES W. BOLICK.
