' HEAD FOR LOOM WARP: BEAMS.

Application led Tune 21;

preventthe total loss ofthe head shouldthe yarn retaining flanges become broken.

Theheads for warp beams suchlas ordinarily used in looms are'usually formedwith in-` tegral parts, namely, a flangewhich defines the 'warp space and adevice to resist move-l ment of the beam in' theletting-.olf of lthe warp threads. 'In loomsfor weaving such fabrics as cotton, gingham or "worsted the position for resisting movementof the beam has' been aY smooth drum around which eX- tends a leather strap,"coiled rope or other flexible `device which exerts friction on vthe drum to serve as alet-off. It has been customary to form the friction-drum and' the *flange all in one piece'and I' find that whenv the flange breaks dueto *fallingy or improper handling-it hasvbeen necessary'heretofore to throw away the whole head. The drum in such cases might be in perfect condition but it must nevertheless-be wasted because ofthe fact that it is'cast integral with'the flange. Moreover the drum is subject to more or less machining during the manufacture ofthe head and these machining `operationsand their costmust belost when any partiof the flange becomes defective. It is an-impor'tant objectv of my present invention to make a beam head wherein the Yflangeandy friction drunrshall be separate but heldtogether Ain suchA away thatrthey will rotate togetherfso that resistance offered lto the movement `of the drum bythe friction devices will be com municat-ed to the warp through `the ange and the beam-barrel connected'thereto.

While the flange and friction drum should lie as close together as possible yet it-.may'bedesirableunder certain conditions to be able to 'move the friction drum longitudinally of the beam with respect to the flange, such for instance as' to accommodate 'slightly varying distances between the supporting lbearings of the beam `on the loom sides,` and this result I achieve by the herein described construction whereby the drum and flange parts arerelativelvmovable. l

-Withthese and other objects in view which willV appear as the description proceeds, ymy

invention resides .in the combination and ar` rangement of parts hereinafterdescribed and set forth in thel claims 1927. Serial No. 200,479.

In the accompanying drawings, wherein I have shown a convenient embodiment of my invention,

Figi 1is a rear' elevation of the beam made according to my present invention, certain 'parts'of .the loom'supporting structurey and let-off devices `being shown in section, Figa'2 1s` an wendeleva'tionfof one of the beam heads looking infthe direction of arrow Fig.- 3 "s a verticalsection onfline 3-3 ofFig. 2,and,

Fig.` 4.is .anA enlarged. horizontal4 section taken on line 4-4 of Fig. 2.

Referring to thedrawings I haveindicated the loom-stand 10 las having supporting bearings 11v onwhichthe beam-is-mounted. n The beam is provided with a barrel -12onfwhich the warp thread is wound, saidL barrel being provided with t-wo or more slots 13 which receive tie'rodsl14..eXtending.the length of the barrel 12. Y y

Each end of the beam isprovided with a head whichin thepresent instance is formed of two parts, the flange. section 20 having a hub 21 and aninside face 22, the inside faces of theflanges defining the space to be occupied by the warp threads. A's shown herein each flange section 20 is provided with one or more tongues 23for a purpose to be described andthe rods 14 extend through the flange sections and carry nuts 24 which bear against the outer' faces of the flange sections to: hold the latter vagainst the core or barrel 12. Each flange section is provided with a supporting gudgeon 25 which'passes through the section 'and'into the adjacent end of the barrel 12. The gudgeons maybe secured to.

v in Fig. 1. vEach drum sect-ion is provided with one of more sockets 36 for each of the tongues 23, said tongues fitting the sockets vsnugly and being held in proper longitudinal position by nut 32 in the hub 31.

' YIt will be obvious that assemblage of the two-part head and the barrel is accomplished by fitting the end of the barrel in a shouldered recess 37 in the head, and passing the tierodIs` 14 through the shoulder, as illustrated in lig. 3.

lVhen assembled as set forth herein the tongues 2? and sockets 36 will cooperate to require the flange portion 20 and the corresponding drum portion 30 to rotate in unison about the axis of the gudgeons and the rib 34 on the drum portion will cooperate With the rim 26 to define a space for the reception of the friction rope, cord, drum or other flexible let-off elementindicated at 35. So long as the parts remain intact the beam Will operate in the usual manner Vbut should one of the llanges become broken the corresponding drum can be removed and the damaged flange replaced, after Which the same drum portion can be put in place and the beam restored to usefulness. In this Way the cost of making repairs is considerably lessened. I have described the replacement as being due to the breaking of the flange portion 20 as this has been found the part to require replacement in actual practice, but the invention of course is also useful should the drum be broken While the flange portion is uninjured.

From Vthe foregoing it Will be seen that I have provided a tvvo part head for a Warp beam including yarn restraining flange portions secured to the beam barrel and a separate drum portion to cooperate with the letoff ofthe loom,.these portions being interlocked sothat movement of the flange under the influence of the feeding of the Warp is communicated to the drum and resisted by the friction element 35.

Having thus described my invention it Will be apparent that changes and modifications may be made therein by those skilled in theart Without departing from the spirit and scope of the invention and I do not Wish to be limited to the details herein disclosed, but 'what I claim is:

l. In a. Warp beam for looms, a cylindrical barrel for the Warp, a flange member secured to the barrel and having a tongue, a friction d rum formed independently of the flange member but held in fixed longitudinal position with respect to the barrel and having a socket, said socket to receive the tongue t-o form interlocking means connecting the flange and drum'members to act independently of the barrel to prevent relative angular movement of said flange and drum members and cause the drum member to rotate With the barrel. i

2. In a warp beam for looms, a cylindrical barrel for thc warp, a flange member held in fixed angular relation with respect to the barrel, a friction drum member formed separately from the flange member and held against longitudinal movement With respect to the barrel, and a projection formed on one means formed on the members and acting independently of the barrel to prevent relative angular movement thereof and to cause the drum member to move angularly With the barrel. i

4. In a Warp beam for looms, a cylindrical barrel for the Warp, a flange member held in fixed angular position with respect to the barrel, a gudgeon extending from the barrel through the flange member, a drum member secured to the gudgeon and formed independently of theV flange member, and inter-engaging means formed on the flange and drum members and acting independently of the barrel to prevent relative angular movement thereof and cause the barrel and the drum member to move together angularly.

5. In a Warp beam for looms, a cylindrical barrel for the Warp, a flange member held in fixed angular relation with respect to the barrel, a supporting gudgeon extending from the barrel through the flange member, a drum member formedvindependently of the flange member and movable longitudinally along the gudgeon but normally held to said gudgeon in fixed longitudinal position with respect to the barrel, and inter-engaging means formed on the flange and drum members and acting independently of the barrel to prevent relative angular movement of said members and to cause said drum member to move angularly with the barrel.

6. In a Warp beam for a loom operating with a device effective to resist rotary movement of the beam, a substantially cylidrical barrel forming` the body of the beam,`a flange secured tothe barreland having a portion extending substantially perpendicular to the barrel to define one side of the Warp space, and a friction drum having a portion substantially concentric with the axis of the barrel, said portion having a rim opposite the aforesaid flange on one side and on the other side abutting said flange to form therewith a space to receive the device.

7. In a Warp beam forV a loom operating vvith a device effective to resist rotary movement of the beam. a substantiallycylindrical barrel forming thc body of the beam, a flange secured to the barrel and having a Warp .spaced limiting portion substantially perpendicular to the barrel, a friction drum formed separate from the flange and having a cylindrical surface terminating at one side in the rim and having the other side in abutment with the aforesaid flange, said flange together with the cylindrical portion of the friction member and the rim of the latter delining a space for the friction device.

8. In a Warp beam for a loom operating with a device effective to resist rotary movement of the beam, a substantially cylindrical barrel forming the body of the beam7 a Warp 10 limiting flange secured to the end of the barrel and havin(r a ortion extendimlr substantiall b 'c y perpendicular to said barrel, a friction member formed separate from said flange andv having a cylindrical portion at one end of which is formed a rim and the other end of which lies in substantial Contact before said perpendicular portion of the flange to define with the latter a space for the device and in* terengaging means between the flange and drum to cause said flange and drum to move in unison and in substantially fixed angular' position relatively to the Warp beam.

In testimony whereof I'have hereunto affixed my signature.
