4 Claims. (Cl. 242-124) This invention relates to improvements in warp beam or like constructions such as are used in the textile arts, and relates more particularly to improved means for obtaining a secure connection between the disc-like head and the cylinder or barrel.

Reference is made to the divisional and continuation-in-part application of Samuel A. Harris and Charles A. Sinqueeld Serial Number 339,594, led March 2, 1953.

It has been a problem in this art to mount the head securely with respect to the barrel so that the head will withstand the pressures caused by the material wound on the barrel and th A principal object of this invention is to provide a novel joint between the barrel and the head which will withstand the forces to which it is subjected. Several representative embodiments of the invention are illustrated and described in the annexed drawings and following specification.

The invention is characterized generally by a novel connection including `an expansible annular member or device, such'as a collar or split ring, which is inserted into the bore of the barrel adjacent an end thereof, and expanded into contact therewith, means being provided to effect a lockingconnection of the annular member to the barrel. The expansible collar, member, or device forms part of a new and improved arrangement for connecting the head to the barrel. In certain forms of the invention, a hub is locked to the barrel, and the beam headis secured to the hub. v

In the drawings:

Figure 1 is a central, vertical, sectional view of a construction embodying the invention; y

Figure 2 is a central, vertical, sectional view of a modified constructiom' Figure 3 is a central, vertical, sectional view of a further modified construction;

Figure 4 is a central, vertical, sectional view of still a further modified construction; and Figure 5 is a reduced front elevation of form shown in Figure 4.

The warp beam construction illustrated inA Figure 1 comprises a barrel Inc and a head generally designated ||0 at one end of the barrel. The opposite end of the barrel may be equipped with a similar head (not shown). The contacting faces of `the barrel luc and the periphery of a collar |30 within the barrel bore are provided respectively with registering annular grooves or recesses |2c, |20', adapted to receive an expansi- .the I ble ring 23. 'Ihe circular member or collar |30 is provided with radially disposed threaded sockets one of which is shown at 24 connectingv theV inner bore of the collar with the bottom of the recess |20. Set screws, one of which is shown at 25, threaded in the sockets 24 may be brought to bear against the'inner wall of the ring 23 to expand it so that its outer portion enters the recess |20 formed in the barrel |0c. The head ||c, of plywood, is supported by a metal hub comprising inner and outer face plates 26 and 21, respectively, the inner face plate 26 having a anged rim 26 Awhich is frictionally seated within the bore of the collar |30. The head llc has a centrally disposed recess ||c formed on its outer face, and the outer face plate 21 has acorrespondingly shaped centrally disposed offset 21 which is seated in the recess |10. The two face plates 26 and 21 are securely connected together, with the head ||0 between them, by means of bolts, rivets, or other suitable fastening vmeans 28. The inner face plate 26, the head ||c, and the outer face plate 21 are provided With a common central bore, generally designated 29, into which the hub 20a of a gudgeon or stub shaft is inserted, the flanged portion 2|an of the hub 20an being seated in a recess |901.I formed in the outer face plate 21 within the oiset 21.

The beam head, forming a complete unit including the face plates 26 and 21, is secured as a unit to the collar |30 by bolts I1c passing through the face plate 21, head llc, and intov the threaded sockets in the collar |30.

In assembling the construction shown in Figure 1, the collar |30, with the ring 23 seated in the recess |20', will first be inserted in the bore of the barrel |00, and the outer edge of the collar will be aligned with the edge of the barrel. As the recesses |20, |20 are located equal distances from the outer edges of the barrel Ic and the collar |30 respectively, the recesses will then register with each other. The set screws 25 may then be turned so as to expand the split ring 23, forcing it partially into the barrel recess |20, the remaining ring portion remaining in the collar recess |20. The ring 23 thus acts as a key between the barrel |00 and collar |30, eectively locking them together. The rim 26' of the face plate 26, with its attached parts, may then be seated in the bore of collar |30, and the entire head unit secured to the collar by means of bolts |10.

A modification is disclosed in Figure 2. In

-this construction, a circular flanged or rimmed face plate member 26d is seated directly within the bore of the barrel 10d instead of within a separate collar as in Figure 1. The outer face 26d of the face plate is spaced slightly inwardly from the end of the barrel, leaving the barrel end projecting slightly for a purpose which will be describedv later.

The meetingifacespfthe bore of the barrel 10d and the collar part or rim I3d of the face plate 26d are provided respectively with oppositely dis,-J posed annular recesses or grooves lzirand( 172g". An expansible split ring 23d is seat'ed the recess |211 of the rim @gli Theu ldis provided with radially spacegithreadedsoelgets` 24d, and set screws 25d arehfeadedlin eaclL 15 denwy, andstheadjacent barrel end, axially of of these sockets.

Changes in the construction and design may be made without departing from the scope of the invention as defined by the appended claims.

Having thus described our invention, we claim:

1. In a warp beam construction, a head, a barrel having a circumferential recess in the bore thereof spaced from the end of the barrel; a collar seated in said bore, means expansible into said recess to hold said collar against movement with respect to said bore toward said barrel end, the beam head comprising a disk having a hub portion extending into the bore of said barrel, and circumferentially spaced screws for securing said disk to said collar.

2. In a warp beam construction, a beam head, a tubular barrel, having an annular recess in the bore thereof adjacent its end, a collar seated in said bore, said collar having a diameter substantially the same as that of said bore, and having a recess at one end in alignment with the recess in said bore, a ring seated partially in each recess and keying said collar and barrel so that the collar cannot be displaced towards the adjacent end of the barrel, a flanged hub extending par- CII tially into said barrel, said head being seated on said hub between the hub flange and the adjacent end of the barrel, and circumferentially spaced screws for locking said hub to said collar.

3. In a warp beam construction, a tubular barrel having an annular recess formed internally adjacent an end of said barrel, an expansible bore, and circumferentially spaced screws connecting said head structure to said circular member and holding said circular member against said ring and holding said head structure against said barrel end and holding said hub part in said barrel bore.

4. In a warp beam construction, a tubular barrel having a counterbore extending inwardly from. an end of said barrel and forming a shoulder facing towards said barrel end and an annular recess formed internally in the counterbored part of the barrel between said shoulder and said barrel end, an expansible ring expansionltted into said recess and projecting radially inwardly of the barrel bore, a circular member having a radial face disposed within said counterbore on the side of said ring remote from said barrel end, a head structure at said barrel end, and means connecting said head structure to said circular member and holding said circular member against said ring and holding said head structure against said barrel end, the distance between said shoulder and said barrel end axially of said barrel being not less than the dimension of said circular member axially of said barrel, whereby said circular member may be moved to a position determined by its abutment with said shoulder in which said circular member is disposed axially inwardly of said recess, and fitting of said ring into said recess is facilitated.
