ALFREDO. TATE, ornnw YORK, N. Y.
To all 107mm, t may concern.'
Be it known that I, ALFRED OTATE, av
subject of the King of Great Britain, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Calender-Rolls, of which the followingis a disclosure.v
My invention relates to calender or Shreiner rolls such, as arecommonly employed for finishing cotton and other fabrlcs.y Y
The objects of my invention are to construct a roll of this kind having a removable outer shell or surface which will be strong and light and which will be soconst'ructed `and arranged that the'outer shell `can be readily removed and interchanged, also to provide a roll of this kind with heating means so disposed as to effectively heat the surface of theV roll and maintain it at aneven temperature. A further object is to soconstruct the roll that it will maintain its cylindrical shape under heavy duty, although constructed of relatively lightelements.
In the drawing accompanying and forming a part of this specification, I yhave illustrated the preferred embodiment of my 1nvention. In this drawingi Figure l is an end view partly in section of the complete roll.
Fig. 2 is a side elevation partly in section of the roll. y
Referring in detail to the structure shown,
tions 3, which function as spokes or thrust members to support the outerwall of the roll on the hub. Inasmuch as thesel rolls are of considerable length, it is preferred yto make these thrust members in short sections as shown in Fig. 2. The outer ends of the thrust members bear against wedge members 4f, which in turn bear against and tend to hold the elongated stiifening members 5 against the innerorsupporting drum or cylinder G. The wedge members 4. are heat insulated from the stiffening members 5 by a suitable insulation 7. Each stiffening member is provided with a Vcavity 8 in which there is inserted an electric heater shown in the form of a coil 9. The outside cylinder l0 which for some operations is formed with special surfaces is removable and may readily be removed when the face plate 11 is `specificati@-o'f Lettersratni. Patented Aug, 23, 1921 Application ined Januaryaa, 1921. serial-No. 440,862..v
detached." In this connection, attention is y" called to the fact that the spokes or thrust Ymembers 3 are tangential'ly disposed'fwith thrust the members 5 outwardly against the inside wall of drum Gand thus'hold the surface of the roll 10 against its work. `The outwardthrust. of the spokes also operates to maintain the `roll a true cylinder. In this kway, vI find that a very satisfactory construction is obtained with a minimum of material. Moreover, when the roll is idle, the spokes assume the tangential position vand allow the supporting cylinder 6 to-contract sufficiently to allow the outer cylinder to be readily withdrawn andreplaced. It will be noted that a pin l2 on the opposite end of each of the wedges is arranged `to move in a short slot 13 cut in the end plates 1l.k ,These slots allow the spokes to move from their normal tangential position into radial position butdo not allow them to gor beyond this radial position.
I am aware that various modifications may bey made and Idesire protection vas to all such modifications as come within the scope of my claims. f
What I claim as my invention is:
l. A roll of the kind described comprising a Ahub member, a removable calender cylinder, means for supporting the cylinder on the hub comprising a series of compression spokes extending outwardly from the hub, each spoke being disposed at a slight angle to a line extending from the center ofthe hub outwardly tothe spoke. f
2. A roll of the kind described comprising means for supporting the cylinder on the hub comprising a series of compression spokes extending outwardly from the-hub,
each spoke being disposed at a slight angle t to a radial line extending from the center 'of the hub to the spoke, the inclination of the spokes being such that they tend to assume radial positions when the drum is rotated in service.
3. A roll of the kind described comprising an outer removablecylinder, an inner cylinder, an interior back or support `for the inner cylinder comprising elongated stiiening members triangular in cross section, Wedge members disposed between and adapted to force tlie'stili'eiiing members apart, a hub and thrust members extending vfromV the hub to the Wedges.
4L. A roll of the kind described comprising anvouter removable cylinder, an inner cylinder, an interior back or support 'for the inner cylinder comprising elongated stiffening'members triangular in cross sections, Wedge members disposedbetiveen and adapted to torce the stifening members apart, va hub and thrust members extending from the hub to the Wedges, the thrust members being inclined at their outer ends in the direction of rotation.
5. A roll of the kind ,described comprising an outer removable cylinder, an inner Vsupporting cylinder, elongated stii'lening members disposed on the inside of the supporting cylinder, means for supplying heat to the interior of saidY stifl'ening members,
`Wedge members so disposed as to hold the stiffening members apart and in contact with the supporting cylinder' and means for forc- Ving the wedges into position.
`means inclosedwitliin said stiil'ening inembers, Wedge members so disposed as to hold the stifening members apart and in contact with the supporting cylinder, `means for forcing the Wedges against the stiifening members and heat insulating means between said Wedges and said stiifening members.
7. A roll of the kind described comprising a cylinder, a hub ffor said cylinder, segmcir tal longitudinal stilening members for said cylincler,wveclging members for forcing said sti'liening members againstl said cylinder, said ivedging members having projecting pins at their-ends, `means for forcing said Wedging members against said sti'lfening members, and an apertured plate engaging said pins for limitngfthe movement of said nfedging ,members .ALFRED O.
