- BEAM HEAD.

Application filed April 18, 1922i. Serial No. 554,909. 7

To all whom it mctyjconcern [Be it known that'Ij FRANK Mossnnne, a

citizen of the United States, residing at Attleboro, in the county of Bristol andState of Massachusetts, havejnvented certain new and useful Improvements in Beam Heads of which the following is; aspecification.

This invention relates to an improvement is the construction of beam heads andthe like by which the head is adapted to be adjustably connected-to a beam-or body on which 1 yarn or other 'material may be wound; and theobje'ct of'thisinventionis to provide a he'ad'of this character having a hub member adjustably mounted thereon whereby the hub may be contracted and moved radially bodily to bind the head in adjusted position upon the-beam.

A further object of the invention is to provide means whereby the ends of the radiating arms of the hub sections'are adj ust ably attached to the head-plate instead of being permanently or fixedly attached thereto as has heretofore been the case by which construction these radiating arms maybe moved radially and [so permit a greater range of movement to cause the hub member to betterfit and be more effectually clamped about the beam to connect the head thereto.

With these and other objects in view, the invention'consists ofcertain novel features of construction, as 'will' be more fully described, and particularly pointedout inthe appended claims. .7

In the accompanying drawings:

Figure l is aside elevation illustrating a pair'of my improved beamheads adjustably mounted upon a beam. r i

Figure 2 is a faceview ofmyimproved beam-head showing the general arrange-- ment of thedifferen't sections of the hub.

Figure 3 is a section. on line 3-3 of Figure 2 showing improved means for de tacha-bly securing the middle portion ofthe hub section to the plate.

Figure 4 is a perspective view showing one of the lugs which is employed in adjustably securing the hubisections, thebody portion of whichjug is adapted to be weld'ed to the head. i

Fignre 5 is' a perspective view of one of the hub sections detached showing the lugreceivingslots therein.

into which the finger portion of the lug'is adjustably inserted. Figure 7 is a detail showing the headed inner end ofoneiof' the lugs.

It is foundin practice in the construction ofbeam-heads of this character necessary to so construct the hubportion of the head that itmay be contracted to'bind the head in adjusted position on the beam, and one practical construction is to form the same 111 sections having cooperating rad ating arms, which arms have heretofore, had

some portion fixedly attached to the head and by which construction thecontracting action of the hub was materially limited. My present improved construction is the provision of means whereby the different sections are mounted to "float upon'the head and are adapted to be adjusted bodily to contract the hub securely about the beam, and the following is a detailed description accomplished I With reference to'the drawings, 10 designates the usual body portion of a warp- 'of one means by which this result may be 77 beamqwhich in this particular case is usually 1' constructed Of'WOOd but which of course,

may be made of any suitable material.

In the making of beams of this character the head members 11 are preferably so con structed that they may be adjusted longi tudinally along the length of'the body por eon of the beam in order to regulate its working length.

It is also one of the objects of'the invention to construct both the head-plate and the hub sections of sheet metalwhereby the" whole may be made very light in weight and thehub sufficiently yieldable to be readily contracted to clamp the same upon the body portion'and hold the'head in any adjusted positionthereon. l

The periphery of this head-plate'is preferably rolled outwardlyas at 12; to provide a stiffening flange therefor, and the center of this plate is cut out as at 13 to permit the passage of the end of the beam therethrou gh.

The hub member 14' is preferably. constructed of four separate sections, each having a body portion 16 formed on the arclof a circle with radiatingv end members 17 all set edgeways against the-outer face ofthehead-plate, and at right angles to each other. 1

The radiating end members of each section are spaced apart as at. 1 8 and the end of each section is pierced as at 19 to receive the reduced neck portion 20 of the lug 21 to slide thereinto, the outer end of this reduced neck portion being headed over after having been positioned in the slot to prevent the.

outer ends of these opposite end members from drawing inward toward each other under tension of the binding bolt 24, presently described, the body portion of the lug being then permanently secured, preferably by a spot-welding operation, to the outer face of the head-plate thereby eliminating the usual riveting operation employed for this purpose. v

The body portion of each section is also slotted as at 22, to slidably receive the reduced ends of the lugs 23. ,7

In order to contract these hub members to bind the head in adjusted position on the beam I have provided binding bolts 24 which pass through the adjacent arms 17 of the different hub sections whereby'by setting up the nuts on these bolts the different sections are caused to move bodily inwardly tobecontracted and so lock the head see curely to the beam. f

In some instances the head-plate itself is formed in sections in which case I provide guide fingers 25 and 26 and spot weld the different sections to hold the plate sections in alignment or in the same plane with each other.

By my improved construction of beam head I am enabled to do away with the usual cumbersome cast iron hub which heretofore has been employed for this purpose and have provided one which is much lighter in weight, less expensive to construct, is stronger and more durable and by its use the contractible members vof the'hub may permanently secured to the outer face of the head-plate by a welding operation whereby the inner or working face offthe head is leftplain and smooth, then-again by my particular construction the hub sections having radiating arms are set edgeways against the face of the head-plate. the plate is materially stiffened and one of comparatively light weight may be employed, and by the use, of my improved head-plate the hub may be readily contracted by a free bodily movement of its sections to grip and bind the body portionv ,of thebeam and hold the head in any adjustedposition along its length. a

The foregoing description is directed solely towards the construction illustrated, butl desire it ,to be understood that I reserve theprivilege. ofaresorting to all the mechanical: changesto which the device is susceptible. the invention being defined, and limited only bythe terms of the appended claims. 7 Y Y Iclaimt 1.
