Patented Sept. 14, 1948 UNITED STATES PATENT oFFlcE ADJUSTABLE HEADS FOR PAPER WINDING REELS Leo Leas, Vicksburg', Mich., assigner to Lee Paper Company, Vicksburg, Mich., a corporationI of Michigan Application February 13, 1946, Serial No. 647.298

l This invention relates to improvements in adjustable heads for paper winding reels.

The main objects of this invention are: First, to provide a reel for reeling paper as it is discharged from paper making machines and for other Auses where wide webs of paper are to be reeled. which is strong and durablein structure and one which may be readily adjusted to webs of different widths.

Second, to provide a structure vhaving these advantages which may be very easily and accurately adjusted, and one in which the adjusted Fig. 2.

In the embodiment of this invention illustrated, the main shaft i is supported in suitable bearings and driven at suitable speeds for the par- .ticular work.

The reel illustrated is provided with end heads 2 and an intermediate head i to which the reel spool bars 4i are flxedly secured by the screws 4, the heads being provided with a plurality of faces t so that the Vbars are more eiectively supported when clamped thereto. The heads are axially spaced on the shaft and keyed thereto as indicated at 6. The reel flanges 'i are annular, having an internal diameter sufficient to loosely embrace the spool bars as is shown in the drawing.

These flanges are supported for axial adjustment by means of the axially adjustable sleeves l. slidably supported on the shaft I. Thesesleeves are provided with nuts afixedly supported by the arms iii projecting from the sleeve to receive the screw portion il of the adjusting shaft i2. This adjusting shaft is arranged through adjacent head members and is provided with abutment collars I3 to preventaxial movement of the shaft while permitting its rotative movement.

The flanges 1 are supported by angled brackets It disposed with their inner arms il radially and secured to the sides of the sleeve at "il 6 Claims. (Cl. 242-124) tudinally between adjacent support bars and are secured to the outer sides of the reel flanges by the clips or plates Il. 1

The adjusting shaft i2 is provided with a sprocket Il at its outer end, this sprocket being connected by the sprocket chain 20 to the sprocket 2| which constitutes a driving sprocket rotatably mounted on the shaft l and provided with a hand wheel 22 for convenience in adjustment.

The driving sprocket 2i is secured in its adjusted position by means of the set screws Il.

It will be understood that in use the entire structure rotates as a unit. It will be understood that the second flange-is supported and adjusted in the same manner as that shown in lefthand end of the figures and described.

The sprocket chain 20 is provided with an idler 24 carried by the spindle 25. For convenience in assembling the sleeve I is formed in sections having opposed ears 28 receiving the screws 21 whereby the sleeve sections are secured together. The outer arms of the angle brackets il are supported by the sleeve for longitudinal adjustment between the spool bars 4I.

The structure is capable of handling heavy loads and has a very considerable variation in thevmatter of accommodating webs of different widths. v

The flanges may be accurately adjusted with' edges of the web to insure uniform and accurate winding, and also to accommodate webs of widely varying width.

to illustrate or describe other embodiments which are contemplated, as it is believed that this disclosure will enable those skilled in the art to` eimbody or adapt the invention as may be des red.

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent is: v

i. In a winding reel, the combination of a shaft. end and intermediate. reel head members axially spaced on said shaft and keyed thereto, spool bars secured to said head members in angularly spaced relation, annular flanges embracing said bars, and means for adjusting and supporting said flanges. each comprising a sleeve axially slidable on said shaft, angled supporting brackets having their inner arms disposed radially and secured to said sleeve, their outer arms being disposed longitudinally between certain of Outer longitudinal arms il are disposed longithe spool bars and secured at their outer ends to driven sprocket on its projecting end, said screwA being radially offset from said shaft, said sleeve t being provided with a nut coacting with said screw, and a driving sprocket rotatable on said reel lshaft at the outerv side of the end member 'and having sprocket chain connection with the driven sprocket on said screw, said driving sprocket being provided with a hand wheel and with means for securing it to said reel shaft in its adjusted position.

2. In a` winding reel, the combination of a shaft, end and intermediate reel head members axially spaced on said shaft and keyed thereto, spool bars secured to said head members in angularly spaced relation, annular flanges embracing said bars, and means for adjusting and supporting said flanges, 4each comprising. sleeves axially slidabie on said shaft, angled supporting brackets having their inner'arms disposed radially and secured'to said sleeve, their outer arms being disposedlongitudinally between certain of the spool bars and secured at their outer ends to the outer sides of the flange, andan adjusting screw rotatively mounted in adjacent end and intermediate head members and radially offset from said shaft, said sleeve being provided with a nut coacting with said screw.

3. In a. winding reel, the combination of a. shaft, reel head members axially spaced on said shaft and keyed thereto, spool bars secured to said head members in angularly spaced relation,

\ having sprocket chain connection with the driven sprocket on said screw, said driving sprocket being provided with a hand wheel and with means for' securing it to said reel shaft in its adjusted position. y

4:.v In a winding reel, the combination, of a shaft, reel head members axially spaced on said shaft and lkeyed thereto, spool bars secured to said head members in angularly spaced relation,

an -annular flange embracing said bars, andl means for adjusting and supporting said flange,

l ment carried thereby, an annularange eman annular flange embracing said bars, and means for adjusting and supporting said flange, comprising a sleeve axially slidabie on said shaft,

said screw being radially offset from said shaft,

said sleeve being provided with a nut coacting with said screw and a driving sprocket rotatable on said reel shaft at the outer side of the head member, through which the screw projects, and

bracing said spool element for axial adjustment relative thereto, a sleeve disposed on said shaft between said head members for axial adjust.

ment, flange supporting brackets carried by said sleeve, a flange adjusting shaft -mounted on said head members and having a threaded portion, said sleeve being provided with a coacting nut element, and a driving gear for said shaft rotatable on said reel shaft for manual adjustment and having driving connection to said adjusting shaft.

6. In a winding reel, the combination of a shaft, reel head members and a reel spool elemeans for adjusting said sleeve from the outer side oil one of said head members.
