Application fi1ed June 19, 1926. Serial No. 117,207.

Our invention relates to frames for cloth boards and similar articles. The type of cloth board for which these frames are intended is that in which the frame is of generally open structure, includingside and end members, with or withoutone or more intermediate cross pieces, and is covered with a tightly applied tubular envelope which .is usually paper of substantial thickness, this envelope covering the broad faces and longi tudinal edges of the frame. In this type of board, if the frame is properlyconstructed and the envelope properly applied, they will .mutually reenforce each other and produce a board or winder having great strength and stiffness and other desirable characteristics referred to later. i

An important object of the. inventionis to provide a frame which is inherently very stiff and strong, and highly resistant to strains appliedto it in'the operation of winding fabric upon it or in handling the cloth bolt so produced, and is also especial-V ly adapted for co-operation with the paper envelope which additionally strengthens and reenforces the frame, in the manner above referred to.

Another object is to provide a frame and also being especially adapted for simple and easy assembly with the cross pieces,

either byhand operations or partly or entirely automatic machinery, one reason for this adaptability being the symmetrical cross sectional form of the members which admits of their application to the cross pieces in any rotative position. 1

Another objectistov provide end cross-' pieces of improved form, including end portions which overlap the ends of the side' members and resist inward thrust applied by the chucks of the winding machine, these ends being contoured to match the semicylindrical contour of the side members, and

the outer faces of theend cross-pieces be ing smooth, flat and flush to properly red I ceive and maintain end labels in proper condition; and further, to provide improved interlockingformations on the end pieces and side members, which produce joints which are very stiff and resistant to angular deformation of the frame and are also devised to admit of easy and'accurate assembly, either by hand or machine operations;

A particular object is to provide a struc ture which admits of the use, in certain cases, of tubular paper side pieces, which are probablythe mosteconomical devicesthat can be I material,and to realize at the same time some vor all of the other objectsor advantages above and hereafter mentioned.

The characteristics and advantages of the invention are further sufliciently explained in connection with the following detail de 'S CIlpliOIl of the accompanying drawing,

which shows representative embodiments of the invention. After considering these eX-I amples, skilled persons will understandthat many variations may be made, and 1' contemplate the employment of any structures that employed for this purpose, in connection with cross members of'wood or analogous are properly within the scope of the appended claims. 7 V.

In the drawings: 7 r Fig. 1 is a perspective view of a frame embodying the invention in one form.

Fig. 2 is a fragmentary view,- partly in section in the longitudinal central plane.

Fig. 3 is a plan view of a frame of modiiied structure. 7 i

Fig. 4; is a sectionaldetail thereof; The invention contemplates the employment of side members 1, Fig. 1, or 1, Fig.

3, which are of symmetrical and preferably circular cross section, and which may be either of tubular section, as 1, or solid section, as 1*; and which may beof paper or analogous fibrous composition, as 1, which represents a standard 'or special form of papertube, which is a structure consisting of several turns or laininations of fibrous sheet material, suchas chipboard, pulp board or other .paper stock, either straight-wound or spiral-wound, with suitable adhesive as a binder or strengtheningmaterial, or may be as at 1*, of wood or analogous material.

In combination with such side members we employ cross pieces including the end pieces 2, Fig. 1, or2, Fig, 3, and when necessary,

depending on ;the lengtlr'of-the frame. or other conslderatlons, one or more mtermed1ate cross pieces 3, Figs. 1 and 3. De-

sirably ,-these cross pieces areof wood .or,

analogous material, but in the broader aspect of the invention arenot so limited,an d may be of other material.

In each form of frame, the side and send members have connecting or interlocking formations, which have generally similar characteristics in thentwo forms, but are specifically.different. Thus, in both forms, the .ends'ofthe end pieces are semi-cylindrically rounded .asat; tto conform ,to the semi-round formation of the side pieces, and these portionsof. theendin-embers overlap V the ends ofv the side pieces so that the smooth, I

rounded contourof thehoardedges in no broken both along the side members and the the. side members and resist any inward .stralns-apphed to the end pieces.

These boards areplaced 111 winding machines wh ch 7 havechucks orv holders which exert strong end pressure on the end pieces tending to push them inward, and these strains are directly transferred by the end portions 4 to the ends of the side members and evidently theiend pieces cannot be displaced inward except by' complete crushing of the side members, which-are amply strong to resist the pressure.

W'hen thecloth boards are so placed in the winding machine, they are revolved to, wind the fabriconthe board to form a bolt, and thefabric is placed under tension, whichis often, very considerable, involving severe strains uponthe boardor its. frame structure, and the present frames are amply strong and sti fi to resist even the heaviestw vinding teusion, as willsufficiently.appear from further description.

Afcomrnon characteristic of the end and sidepiece connection in both forms of frame, isthatthe respective pieces have interfitting formations, or dowel .and socket formations,

providing a strong and secure interlocking connection, and the end pieces also have 'wall formations engaging substantial segments of the ends 'of theside members, to provide ad ditional stifine ss at the corner joints. 7 Thus, inFi'g's. 1 and2, the'end pieces are cut (by a suitabletool,such as a hollowvbit) to provide integral dowels, these extending from annular shoulders 7 about the outer segments of the dowels, these shoulderscontinuingintopart-cylindrical slots 8 separating the dowels from walls 9 of the end pieces, thesewalls' being-substantially semicylindrical and terminating in edges 10 which are flush with end segments of the side members. Otherwise stated, theseedges 1O constitute ends of. the inwardportions .of the flat faces 11, which are tangent. to the surfaces of the side.pieces. The dowels and the walls 9 are dimensioned to have a sub stantially tight sliding fit into and about the ends .of the side members, as sufficientlyunderstood in Fig. 2, so that the: parts firmly interlock, and usually glue is applied before assembly, toinsure permanent connection. zVhen theparts are connected the dowels of substantial length fitting in the side members and .the bearing of the inner'segments of the side members of substantial area,

against walls 9, providea very strong and stiff brace against angularor other distortion of the frame and board.

To facilitate assembly, desirably,'the ends of the dowels are rounded or beveled as at 12, and the inner edges of walls 9 are also tapered or beveled asat 18, so that the tu bular side members are easily and practically automatically guided intopositionin the assembling operation. This is especially important in assembling the parts withan automatic or other machine in which it is only necessary to approximately position the respective parts, whereupon they are brought into proper engagement by inward move ment of the end pieces in relation tothe side members. a, V

In the form ,SllOWItllTFlgS, 3 and 4, where the side members are desirably of solid section, they are formed with end dowels 15, whicharedesirably more or less tapered as shown, these dowels being surrounded by annular shoulders 16. The end pieces 2 have the inner faces of their ends formed with flatcircular areasl? to'co-operate' with shoulderslG, the inner contour of these faces being defined by walls 18 of semi-cylindrical form to co-operate with inner segments of the side members, as the-Walls 9 doin the previous example. Centrally inthe circular formations 17, sockets 20 are provided, generally formed to fitthe dowels 15-' or somewhat deeper than the dowels. V The dimension of the wall 18 lengthwise of the board isdesirably greater than the length of the dowel 15,"-so that in assembling theparts the side members may be moved laterally until segments of the full-diameter end-portions of these members engage inward segments of the walls 18,whereupon the dowels are aligned with the sockets 20 and the parts may then be fully interlocked by-inward necessary for the sake of structural strength, 7 comprising tubular paper side members of movement of the end pieces in the lengthwise direction of the board, whereupon the,

are in engagement with walls 18 and the.

parts are braced against diagonal, twisting and other strains, as in the previous case. Glue. is also usually applied to any or all of the engaging surfaces before they are brought together.

The intermediate cross pieces 3 are not subject to strains causing displacement lengthwise of the board, and therefore it is suflicient to make their thickness equal to the outer diameter of the side pieces and to provide in their ends, semi-cylindrical sockets 21 to fit the inner contours of the. side members. Glue is also usually applied to secure the cross members against accidental displacement.

While the dimension of the end members in the longitudinal direction of the frame, from the ends of the side members to the outer faces 5, or in other words, the longitudinal thickness of the end portions 4, may

vary, this dimension, as indicated at A, Fig. 2, is usually greater than would be and'may originally be, for example, as indicated at a. This is to allow sufficient thickness of the-end pieces in the longitudinal direction of the board to provide for variations which often occur in the width of the cloth to be wound thereon. The width of cloth frequently varies as much as extra thickness provided, if the cloth runs narrower, narrow slabs of proper thickness may be cut off from the end pieces or one of them, as indicated infull and dotted lines, in Fig. 2. This enables the textile manufacturer or finisher to easily conform the board length to variations in width of the fabric without keeping on hand a range of slightly-varying board size for this purpose.

the provision of the fiat, smooth end faces 5 for the reception of end labels, and it will be noted that even when substantial slabs are cut from the end pieces, as, and for the reasons above mentioned, the smooth, continuous, fiat surface for label reception is still I tour of the side members, the side and end 50 As above stated, an importantfeature is Y members also having interfitting dowel and f socket formations, the end members also having segmental walls co-operating with.

substantial inward end areas of the side members to provide additional corner bracing.

2. A frame for cloth boards or winders substantial wall thickness and end members having portions overlapping ends of the side members and contoured to agree with the outer contour of the side members, the side and end members also having-interfitting dowel and socket formations, the end members also having segmental walls cooperating with substantialginwa'rd end areas of the side members to provide additional corner bracing.
