Application filed November 1, 1910. Serial No. 590,221.

Be it known that I,]FRANK Mossenno, a citizen oft-he UnitedStates, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Loom-Beams, of which the following is a specification.

My invention relates to loom beams and is facilitate the mounting and dismounting of the heads, to adapt the heads to firm attachment to the beam body regardless of variations in dimensions of the particular body receiving the same, and to effect these ends in a simple, strong, and inexpensive structure.

To the above ends essentially my invention consists in such novel construction, combination and arrangement of parts as are embraced in the appended claims. a

In the accompanying drawings which form a part of this specification, Figure 1, is a side elevation of my novel loom beam, Fig. 2, a front elevation of the same, and Fig. 3, a central vertical section of the same, and Fig. 4, a section on line w w of Fig. 2.

' Like reference characters indicate like parts, throughout the views.

My loom beam in its present embodiment Iv comprises the usual body 1, which may be either solid or hollow according as the material is of wood or metal. Upon this are mounted heads which are identical in de- 7 tail, so that a description of one will sufiice for both.

Each head 2, is pro vided with a peripheral flange 3, in this case a rolled flange; and

has a central aperture, the edge of which is extended to fol-ma flange or hub 4, provided with openings 5, through which loosely pass blocks 7, having preferably enlarged. outer portions 8, provided with longitudinal slots 9, in their outer faces. The bottom faces, 10, of the blocks are concavedto conform to the surface of the body against which they abut.

For stren themn purposes the. head is provided wlth ra ially' disposed hollow ribs 12.

An annular disk .or clamping ring 13, mounted upon the hub 4, has upon its inner margin oblong inclined cavities'14, of greater length than the blocks. adapted to receive the enlarged portions of the latter. The'inclined edges 15, of the disk at the margins of the cavities rest in the slots 9. The periphery of the disk is provided with teeth 17 engaging a worm 18, upon a rod 19, journaled in ears 20, fixed by rivets 22, to the head. The end of the rod is squared as at 23 to accommodate a wrench.

In order to insure against accidental transverse movement of the disk under the influence of the worm, brackets 25, each provided with a slot,.26 to loosely receive the margin of the disk, are fixed by rivets 28 to the body near opposite ends of the worm. There may be one Or more of these brackets.

In applying or clamping the heads to the body, the rods 19, are turnedto rotate the disks 13, whereby the blocks 7, are gradually forced inwardly against the body.

\Vhat I claim is 1. In a loom beam, the combination with the body and heads, the latter being formed with integral flanges upon their central portions constituting hubs around the body, said flanges having openin s, clamping blocks upon the hubs exten ing through said openings, said hubs forming seats for the operative parts, and means surrounding and movable on said flange for inwardly forcing said blocks. Y.

2. 'In a loom beam, the combination with the body and heads, the latter being formed with hubs having openings, clamping blocks mounted upon the hubs and extending through said openings, and rotary means surrounding and movable on said flange for simultaneously inwardly forcing said blocks toward the body.

3. In a loom beam, the combination with the body and heads, of hubs upon the heads provided with openings, clamping blocks slidably mounted in the openings, rotatable clamping disks sleeved upon the hubs and' 4. In a loom beam, the combination with TES PATENT OFFICE.

the body and heads, of hubs upon the heads embracmg the body, clamping blocks upon the hubs, and clamping disks sleeved upon the hubs and provided with inclined bearing faces engaging the blocks and means positively engaging said disks to rotate them and simultaneously operate said clamping blocks against the body.

5. In a loom beam, the combination with the body and heads, of hubs upon the heads engaging the body and provided with openlngs, blocks resting upon the hubs and redially movable inthe openings and provided, with slots, clamping disks sleeved upon the hubs and provided with inclined marginal bearing faces seated in the slots, and means positively engaged with and constructed for rotating the disks to force the blocks against.

said body.

6. In a loom beam, the combination with r i the body and heads, of hubs upon the heads engaging the body and provided with openings, clamping disks surrounding the 'hubs and provided with inclined cavities,

blocks radially movable in the openings and extending into the cavities in contact with the disks'and means positively engaged with the outer periphery of said disks for rotating the latter. v r

7. Ina loom beam, the combination with the body and-heads, of flanges upon the bers upon the head loosely engaging the 8. In a loom beam, and combination'with the body. and heads, of flanges upon the heads constituting hubs around the body,

clamping blocks upon the hubs in contact withthe body, clamping disks; rotatably.

mounted upon the hubs in contact with the blocks provided with teeth, and worms carried by the heads engaging the teeth.

9. In a loom beam, thecombination with a body and heads, the latter having flanges constituting hubs, of clampin blocks upon Said hubs in contact with t e body means rotatably sleeved about saidhubs and v and: having cam portions cooperating with cam portions 'onsaid blocks for simultaneou sly actuating all of said blocks.

' 10. Ina loom bea'm, a body, heads havingflanges constituting hubs around said .body

and having openings, clamping blocks upon said hubs working through said openings,

and means rotatably mounted upon and surrounding said hubs and having cam portions cooperating with cam portions on said blocks and contacting with said blocks for simultaneously actuating the latter.

In testimony whereof I have aflixed my signature in presence of two witnesses.
