Application May 17, 1934, Serial No. 726,143 1 Claim. (o1; 38-67) This invention relates generally to laundry machines and more specifically to machine iron- .ers or mangles of either the chest or cylinder type. wherein a plurality of clothed rolls rotate within a heated chest or drum, the work being ironed as it is passed therebetween.

The work is usually fed into the machine while damp. The heat given off by the heating element passes through the work and the clothed rolls. The resultant exchange tends to cause the work to adhere to the heating medium and rolls but the rotation of the rolls forces the work forward. However, when the machine has been in operation for any considerable period of time the clothed rolls themselves become heated to a high degree and while the rolls will advance the work from the heating medium, nevertheless the tendency is for the work to adhere to the rolls. If this adhesion is not overcome it naturally follows that the work will be wound around the rolls thereby defeating the neat ironing function.

To overcome such hazard, means have been employed, such as a series of strings held between the rolls and the heating medium so as the work is passed it is ironed and will be forced downward or from the rolls. Other means have been to provide a series of fingers arranged tangentially to the rolls and which bear against them in a direction opposite to rotation so that the work is picked from the rolls after it has been ironed.

An objection to such devices is that the life of the cord is short due to the heat and strain applied and the constant friction between the fingers and the rolls rapidly wears out the cloth. With either it is impossible to re-clothe a roll without removing the entire work stripping means.

The present invention is designed to overcome these and other objections and, therefore has for its object the provision of means that will prevent the adhesion of work to the rolls and effectively strip it therefrom during the ironing process.

Another object is to provide such means that can be adapted to existing types of machines without altering their present design.

A further object is to provide such stripping means that will not interfere with reclothing the rolls or repairing other parts of the machine.

Other objects will appear and be better understood as the specification proceeds, reference being had to the accompanying drawings forming a part thereof and in which:

Figure 1 is a perspective view of the stripping device assembled as it would be applied to an ironing mangle. I a

Figure 2 is a sectional view, taken on line 2.2 of Figure 1.

Fig. 3 isv a transverse chest type mangle depicting the stripping device applied thereto.

Figure 4 is a plan view of Figure 1.

Figure 5 is a detail disclosing the, manner retaining the strips on the frame.

Thus, it will be seen that the invention resides in the provision of one or more strips adapted to pass beneath the rolls adjacent the beating medium and held in arcuate position by means of a suitable frame.

Referring more specifically to the drawings it will be seen that the numeral l designates a heating element or steam chest, over which revolve padded ironing rolls 2. The work to be ironed, being designated by the numeral 3, performed by passing it between the chest and rolls.

In order to remove the work 3 from'the rolls 2, in the event the work clings to the rolls, there is provided a series of thin narrow flexible strips 4, interposed between the chest I and the rolls 2. The strips are preferably of rust proof metal.

In the chest type of ironing machines shown in the drawings, the strips 4 are mounted in a frame which comprises pairs of end brackets 5, secured as by bolts 6, to convenient end portions of the machine, so that they will clear the end rolls.

In the form shown in the drawings the brackets comprise oblongs each pair of opposed ends being adapted to receive a side bar'l and a tie rod 8.

The side bars i receive sleeves'or collars which are positioned on the side bars in opposed pairs midway between rolls 2.

The sleeves 9 have integral right angle extensions it] which vertically receive slidable uprights H. These uprights may be provided at the upper ends with elbows l2 to receive crossbars [3 or the uprights ii and cross-bars l3 may form integral U shaped members.

To assemble the complete stripping device to an ironing machine, tappings are made at suitable locations in the outer end frame work to receive the bolts 6, or other securing means to hold brackets in position. The brackets, it will be understood, may be of any convenient design so that when in position they will clear the ma-- chine. the side bars I are inserted and suitably secured to the machine by means such as bolts and washers I 4 after first mounting the sleeves 9 thereon.

section of a convention Through suitable borings in the brackets The borings in the brackets are conveniently located so that the side bars I and sleeves 9 will likewise clear the machine. If the brackets are of such design as to require them, the tie rods 8 may then be positioned.

The sleeves 9 are then anchored in location on the cross bars 9 by suitable means such as set screws. P5. The position of opposed sleeves should be midway between rolls 2 so that the inverted U shaped cross bars II when inserted in the extensions IU of the sleeves, will likewise be midway between rolls 2.

The cross bars, it will be noted, are Jvertically adjustable in the extensions [0 of the s1ee'ves 9 and are held in place as by set screws l4. These bars should be located a distance below thelaxes of the rolls 2 for a reason later to be explained.

Up to this point it will be observed that in order to assemble the frame on the ironing machine it was not necessary to disturb any of the" Thus it will be seen that at all times there is free access to the machine and stripping device. A roll can be reclothed without removing the stripping device. Likewise, should a stripper break, it can be replaced without removal of any part of the machine or of any part of the stripping device. The life of the strippers is prolonged by reason of securement below the axis of the ironing rolls as there is less pressure applied when they are thus located when the machine is in operation. The slots afi'ord play or the strippers as the rolls are raised and. lowgrid adapted to be attached lengthwise to the mangle adjacent the end rolls, the cross pieces of the grid being positioned between adjacent rolls; fiexible' strips rigidly secured to the end cross-pieces-of the grid and slidably secured to the intermediate cross pieces, said strips passing between the rolls and ironing surfaces, I

whereby the work to be ironed will pass between $5 the strips and ironing surfaces.
