EMILY M. SAUNDERS, OF BOSTON, MASSACHUSETTS.

t y Maryann-nom..

Specification of Letters Patent. Patented Sept. 28, 1191.5.

Application led January 23, 1915. Serial No. 3,914.

To all 'whom it may concern Be it known that I, EMILY M. SAUNDERS,

a citizen of the United States, and resident of Jamaica Plain, Boston, in the county of Suffolk and-State of Massachusetts, have invented certain new land useful 1mprovements in Mangle-Rolls, of which the following is a specification.l

This invention relates to cloth-covered ironing rolls for mangles, said rolls `being adapted to coperate with heated ironing chambers having concave polished faces in close proximity to the peripheries. of the lrolls, the goods being ironed passing be tween the rolls and theironing chambers, as

shown inthe application of William A..

Saunders, iled Feb. 2,1914, Serial Number The vobject of the invention-is to provlde an improved construction affording uniform strength and rigidity of all parts of the cloth supporting surface of the roll, and' enabling 'the cloth covering to be conveniently secured for use and released for removal.v

Of theaccompanying drawings forming a part of thisspeciication: Figure 1 is a sideelevation. of an ironing roll embodying .the invention; Fig. 2 is a fragmentary longituldinal section of the roll -shown by- Fig. 1;

Fig. 3 is alsection'on line 3-3 of Fig. 2; A

l Fig. 4 is an end elevation of the roll, one

side being shown in section.

- My improved ironing roll is constructed as Vshown in detail by Figs. 1, 2,- 3 and `4,

which may be understood to represent one of a number of rolls with which a mangle is provided as shown'by the above mentioned application. The body 'of the roll is com# posed of a hollow metal cylinder 90 and heads 91, inserted in the ends ofthe cylinder and having flanges 92 bearingon said ends.V

The heads 91 have hubs 93 attached by set screws 94 and. keys 95 (Fig. 4) to the shaft 17. Said shaft is'provided within the cylinder 90 with hubs 96 attached to the shaft by set screws 97 and keys 98 (Fig. .3), the hubs 96 being uniformly spaced from each other and from the heads 91, as indicated by Fig. 1. Each hub 96 has a head or enlargement 99 provided in each of its four sides with dovetail guides 100, which are inclined relatively to the shaft 17 as shown by Fig. 2. With said guides are engaged dovetail slides 101 formed on supporting blocks 102 having segmental outer faces 103 fitting the internal surface of the cylinder 90. The supporting blocks have tapped orifices engaging the threaded inner ends of tension rods 104, the

stitute expansible headsl adapted to be supported by the shaft while contracted, and expanded after Vthe parts are assembled. The expanded heads firmly' support the cylinder 90 at points between the outer heads 91, so thatthe cylinder is rigid from end to .end and cannot be bent or Jsprung by the pressure of unusually thick arts of the goods against the peripher o the, roll.l

The hubs 93 are externa ly threaded and with their threaded portions are engaged sleeves 106 having clamping flanges107, the beaded edges 108 of which confine the in.

l wardly bent portions of the cloth covers 24 against the beveled edges 109 of the heads 91. The rotation of the sleeves. 106 therefore causes the flanges 107 to either secure or release the ends of the cloth cover. A

Having described the invention, 1 claim: l. In a-mangle, a roll composed of ak shaft,

end heads secured to the shaft, intermediate -expansible headslsecuredl to the shaft, a

hollow cylindrical body supported by said heads,'means for expanding'the intermediate heads against the inner surfaceof the body, and a cloth cover on said body.

L', segmental supporting blocks movable onv 2. In a mangle, a roll composed of a shaft, 4press the supporting blocks outwardly end heads secured to the shaft, intermediate against the cylindrical body. l0 expansibleheads secured. to the shaft and In testimony whereof I have aHXed my comprising hubs having inclined guides and signature, in presence of two Witnesses.
