' 6 Claims. (Cl. 29-12s) tween the chest and rolls, but/the invention is more particularly directed to an insulated aluminum cover for the roll and means permanently attached to the roll coacting with complemental means carried by the cover for detnchably securing the cover to the roll.

In connection with the at-workironers of the above character, the respective rolls are provided with a covering of padding material, which in turn is covered with duck or treated fabric which constitutes the ironing surface of the roll and which presents many disadvantages, among which may be noted: that such cover material is stiff and when wrapped around the roll with the trailing end free, in operation, the latter will fold over and crease causing the cover to split, thereby notonly damaging the cover but giving a rough nish to the linen. This type of cover also permits heat to penetrate-through the pad and to the roll, tending to burn up the pad and effecting a loss of heat, which increases the operation cost and slows down production; therefore, the principal object of this invention is the provision of analuminum cover having an insulated surface next to the pad and roll which reects heat therefrom, thereby tending to preserve the pad and such structure, increasing the life of the cover, and giving a smooth finish to the ironed material.v The covers heretofore in use have been secured to the roll at one end by gluing, which requires considerable time and effort to remove upon Wearing out of the cover or because of damage thereto, requiring replacement with a new cover. Also, at times the gluing permits the covers to slip, which requires their replacement, and in order to replace such cover, a complete shut-down of the iron for a considerable time is necessary. Therefore, afurther important object of this invention is the provision of a positive cover-attaching means mounted permanently on the rolls, and provided with anchoring means engageable with complemental means carried by the end of the aluminum cover, thereby enabling the cover to be removed and replaced in a few minutes.

InV an ironing machine of this type employing a plurality of ironing rolls, at a point where the dampened andl cold dat-work or linen enters between the heated chest, and the padded rolls, the initial rolls in operation are continuously wet and in a short time become cornpressed and also cease to absorb the moisture, and if the moisture is Vallowed to remain in the flat-Work it causes a rough-dry finish. Therefore, another important object of this invention is the provision of perforations in the aluminum covers of the initial roll or rolls, depending upon the number of rolls in the particular machine, which perforations allow the moisture to pass into the underlying pad and dry out, whereby a smooth finish is imparted to the material being ironed. l

A still further object of this invention is the provision 2,762# ll Patented Sept. 1,1, 1%956 ice of a novel cover-attaching means and an insulated vthin f flexible aluminum cover that will go once 'around to completely coverthe roll, but the free end of which will remain in place and impart a smooth nish to the ironed material.

Another important object of this invention is the provision of a covering assembly for dat-work ironer rolls comprising an envelope pad, a exible metal cover for the pad, and interlocking means in connection with the roll and metal cover for detachably securing the cover in operativeposition about the roll. 1

With these and other objects in view,- which will become apparent as the description proceeds, the invention resides in the construction, combination andarrangement or" parts, hereinafter more fully described and claimed,

and illustrated in the accompanying drawings, in which like reference characters indicate like parts throughout the several figures, of which:

While myV invention has been shown and described in connection with avmangle or iiatworkironers, it is'adaptable with slight all types of ironers, such as chest, cylinder, combination chest and cylinder type, and home ironing machine.

tion, there is shown generally, va mangle` or atwork ironer A embodying any desir'ednumber of ironingirolls B, inthe present instance there being six of such rolls, by way of' example.l n l The ironer A may have any desired number of rolls B, such as"4 are indicated as 1, 2,v 3, 4, 5 and 6, and which respectively arejo'urnalled at their opposite ends in bearings mounted on' the oppositely disposed side plates 7. The rolls B rotate in concave seats 8 (Fig.l 4) formed in the upper surfaces of the respective steam'chests, 9 located in the bottom portion of the machine A, and which effect heating ofthe respective covers C -enveloping the rollers B, asrand fora purpose directly more fully appearing. These rollsrmaybe in excessr'of'five feet longand diameter of'a foot or more. H eretofore'it' has been difiicult to attach and removecovers from the' rolls, which are usually attached by gluing 'and wheny they become worn or damaged, usually it hasbeen necessary to shut down the machine for' afconsiderable period; and leven then, it has been diicult to readily clean a roll in order to apply a new cover. .y "i

From the above, it will be apparent that I have provided a novel roll cover and 'attaching assembly comprising a cover attaching structureV permanently attached to each padded roll and a-,complemental attaching means formed in the aluminum roll ovemwhereby'lfa covermay .be changed inY a; few minutes' easilyKV and quick1y,'the'reby i effecting a saving in machinestoppage, said insulated f aluminum cover being adapted toj permit the escape' 'f moisture when 'vrequired,V and Vpiovl'des a srrlooftirV solid surface adapted topreuserve the life ofthe pad and while preventing damage to the-pad by ka wasting of heat,Y thereby cutting down productioncost, and at thev same time4 being adapted to withstand hard'fiidcon'tinued usage and to impart a desired smooth finish.
