UNDERGLEARER ROLL Filed July 9, 1941 Patented- Aug. 29, 1944 UNDERGLEARER ROLL Noah E. Lucas, Norwich, Conni, assignorto Noah Lucas, New Britain, Conn.

Application July 9, 1941, Serial No. 401,621 claims. (ci. 19-140) My invention relates to the class of devices above mentioned, andan object of my invention, among others, is the production of an underclearer roll that shall maintain its shape under all conditions to which it is subjected in use; and a further object of the invention is the production of a device of this type that may be readily produced in a comparatively simple manner and that will be particularly effective in the results produced by its operation.

Forms of underclearer rolls embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained are illustrated in the accompanying drawing, in Which- Figure l is a side view of an underclearer roll embodying my invention.

Figure 3 is an end view of the same.

Figure 4 is a view similar to Fig. 2 but illustrating a little different structure. l Figure 5 is an end View of the latter forml of roll.

Figure 6 is a view in central lengthwise section of one end of my underclearer roll embodying a little different form of construction.

Figure 7 is a view similar to Fig. 6 but trating another modication. y

inus- Figure 8 is an isometric view of one end of the roll illustrated in Fig. 7.

Figure 9 is a view similar to Fig. 8 and illustrating the manner kof applying the Cellophane wrapper.

Figure 10 is a view similar trating a modification.

Figure 11 is a View illustrating the manner of forming the outer covering from an'extension of the paper wrapper only Wound several times around the roll to complete the outer jacket.

Owing to the diniculty in showing the sheets in section, due to the thickness of said sheets, they are not separately shown in the sectional views herein or in the end view, Vlout it will be understood that as otherwise shown in the figto Fig. 7 but illusures the sheets lie one against the other and are wound several times around the roll to comprise the parts specifically referred to.

The extreme conditions as to heat and moisture in the rooms in which underclearer rolls are used are such as to strain the ability of the rolls to withstand the harmful effects and unless such rolls are most efciently constructed and in a sential that the rolls shall preserve their true formA and shape in order to prevent any spaces between them and the rolls in connection with which they are used. It is therefore essentialV that the underclearer rolls shall be most rigid and that their rigidity shall be preserved, and my invention illustrated and described herein enables rolls bearing these characteristics to be obtained at comparatively little expense.

Up to the present time it has been the universal custom to employ underclearer rolls made of substances and in a manner to withstand to a certain degree the harmful effects of heat combined with moisture hereinbefore referred to. The construction of such rolls has involved -considerable expense and it has not been appreciated that the life ofsuch rolls could be materially prolonged. This appears to have been a case in which, as in some other arts, the rolls in use were all sufficient and no thought has been given to any improvement, doubtless fromtheff'act that' no improvement was thought to be possible or necessary. No attempt has heretofore been made to improve the structures particularly by protecting the rolls from contact with moisture by the use of an ensheathing material whereby such moisture is prevented from gaining entrance to the material composing the core of the roll.

I have demonstrated that bythe use of'such an encasingmaterial cheap substances such as wood of an inferior grade and othersubstances may be employed and when encased in a material impervious to moisture such rolls may be used indefinitely and for periods much longer than the more expensive rolls now in common use, and while preferably I employ Cellophane as a covering or ensheathing material other substances which would be impervious to moisture will be found to accomplish my purpose.

` In order to eiect my purpose in the production of a roll involving comparatively little expense wood is found to particularly fulfill the requirements, although other material may beemployed and the invention will be vfound to well apply to such rolls. My invention enables such materials to be used whitout being affected by the extreme heat combined with moisture conditionsof the rooms in which they are used, the rolls being encased in a manner to prevent the moisture from gaining access to the bodies or cores of the rolls while the surfaces are maintained in a most satposed in whole or in part of Cellophane or other4 In the particular arrangement shown in Figs. 2 and material or materials impervious to moisture.

3 this sheath is composed of several sheets of Cellophane and paper, one sheet 'of eacliof said -f materials being shown for the purpose of illustra'- tion herein, said sheets being' placed in contact one with the other [and then wound upon theroll. While the exact arrangement is not material, as shown the sheet 8 of Cellophane is placed next to the roll 1 at the'beginning of the winding operation and the sheet 9 ofv paper is placed next to the Cellophane sheet as shown in Fig. 2, it being desirable that the sheet 8 of Cellophone shall extend at least once completely around the roll and as many more times as may seem expedient. The two sheets woundtogether as just explained comprise a sheath I0 which encloses the rolls. 1 and this sheath is enclosed in a jacket II Which may be composed of a spearately formed tube of paper or other Vsimilar material, or this jacket may be formed by making the paper sheet longer than the Cellophane sheet and windingit several times, independently `of the Cellophane sheet, around the roll to complete its formation as hereinbefore shown and described.

To protect the end` of the body 1 from rthe entrance of moisture a cap I2 of materialimpervious to moisture, as vulcanized.. rubber .or metal, is iitted, over the end of the core 1 and has a ange which is extended inwardly to penetrate the end of the sheath and-jacket, as shown in Fig. 2 wherein it is forcefully entered between the jacket VIl and the core 1 and into contact with the endof the sheet I0. This cap may be provided with ribs I3 to prevent the cap from turning and a journal I4 comprising the end of a pin I5 driven` into the end of the core 1 is provided for the purpose of rotatably mounting the roll in suitable bearingstherefor in a manner that will bereadily understood. f *l I In that form of the device shown inFigs. 4 and 5 the body or core I6 of the roll is composed of paper formed in any suitable manner, as by winding a sheet or sheets several times around the structure to obtain the desired thickness, or it may 4be formed in any manner common tothe way of making paperrolls. This structure is similar to that shown in Fig. 2 with the exception that the core I6 is formed with recesses I1 in its ends, a plug I 8, Vpreferably of wood orsimilar material, being secured in said recess. The pin I5, journal I4, and cap I2. may be of the same nature as that shown in Figs. 2 and 3v and the structure is enclosed in a jacket II as shown in said figures. y

In the roll as yshown in Fig. 6 the core or body 1, the sheath I0, and pin I5, journal I4 and jacket Il are formed in substantially the same manner as described and shown with respect to Figs. 2 and 3. A ange I9 is formed on the pin I5 ina manner similar to that shown in Figs, 2 and 4, this flange abutting squarely against a filling 20 which may be composed 0I gli-1.8, Shella,

or other material impervious to moisture this to protect the end of the body or core 1, in a manner that will be readily understood. The device shown in Fig. 7 is similar to that shown in Fig. 6 with the exception that the end of the sheath I0 which is composed of paper and Cellophane, or even of Cellophane alone, is folded over the end of the core as at 2| to complete the sheath I0 and therebyprotect the core as particularly shown in Fig. 8.

v The structure shown in Fig. 10 is quite similar to that disclosed in Fig. 6 with the exception that the entire jacket 221s composed of a winding'of sheets of Cellophane and paper, as hereinbefore described, and a filling 23 of glue, shellac or'similar material impervious to moisture is interposed between the end of the body 1 and the flange I9 on the pin I5.

In that form of the structure shown in Fig. 11 the body or core 1 is enclosed in a sheath I0 formed of a winding of sheets of Cellophane 8 and paper 9 and the jacket, IWI is formed by several windings o f the sheet 9 of paper which is made considerably longer than the sheet orsheets of Cellophane so hthat'I as the Cellophane sheets terminate within the paper winding the latter is continued and wound several times around the roll to complete the jacket II asV hereinbefore explained in connection with Fig. 2. It is to be noted that the core 1 whether-Lof wood orv other material is so enclosed within the jacket comprising the Cellophane and other material that the core may be removed 'when it has outlived its purpose and a new core substituted, thus enabling the jacket to be used indefinitely.

In accordance with the provisions ofthe patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodi-m'ent thereof, vbut I desire to have'it understood that the device shown is only illustrative and thattherinvention maybe carried out by other means and applied to uses other than those above set out.
