GUARD FOR WBINGERS AND NIN@ MACHINES.

Application tiled April l, 1921.

To all rwhom, it may concern:

Be it known that I, FRANK Hannan, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful improvement in Guards for Wringers and Ironing Machines, of which the following is a specification, thp principle of the invention i being hereln explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention, relating, as indicated, to a guard for wringers, ironing machines and the like, is particularly directed to the provision of a simple device which may either be constructed as a part of the ironer or wringer, or may be attached thereto for the purpose of facilitating the feed- -ing of the garments between the rolls, and

for the further purpose of guarding the operator against being vcaught between the operating rollers of the machine. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claim.

The annexed drawing and the following description set forth in detail certain mechanismembodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawing Fig. 1 is a side elevation of my device as applied to a wringer of standard type; Fi 2 is a longitudinal vertical section throug the same; Fig. 3 is a plan view taken below the plane indicated by the line 3 3, Fig. 1; and Fi 4 is a detail section along the line 4 4, ig. 2.

In Fig. 1 l have shown, for purpose of illustration, a wringer of standard type which comprises spaced vertical frame members l, connected, as in the usual manner, by crosspieces and provided with vertically arranged slots 2, in which are mounted the bearing portions or studs 3 of two co-operative rollers 4 and 5. The roller 4 is maintained in operative relation to the roller 5 by means of heavy coil springs 6, the tension of which may be adjusted by means of hand screws 7 carried in the upper portion of the frame members 1, as is customary in devices of this type.

operative operating rolls of the machine. I

understand that it has been proposed to place a lighter and movably mounted guard roller in front of the main co-operative rolls for the protection of the operators hands, but the present invention goes very much further than merely the use of the guard roller referred to, and provides a double guard against injury, as well as providing means which greatly facilitate the feeding of the garments between the main rolls.

'llhe present invention consists of a pair of plates 8 which may be attached to the side faces of the two wringer frame members 1. To these plates 8 are attached horizontally extending frames 9, to the ends of whlch are adjustably mounted rolls 10. The adjustment of these rolls may be had in any convenient manner, such, for example, as by means of bolts 11 operatin against slide blocks 12. Extending aroun the two oppositely arran ed rollers 10, which are of course para el to the main rollers 4 and 5,

between the main rollers 4 and 5, and over a roller 14 carriedbetween the plates 8. All of the rollers referred to are of course in parallel relation.

is an endless belt 13, which is also passed ounted on the extending frames 9.. are

four vertically arranged rods 15, on the upper ends of each pair of which are mounted guard rollers 16. These rods 15 extend a considerable distance below the frames 9 and 'v carry washers or plates 17 at their lower ends, between which and the frame members are mounted compression `springs 18. These compression springs serve to maintain the roller 16 in contact with the upper surface of the belt 13 and in the position shown in Figs. 1 and 2.

ln operation the garments to be passed between the main rollers 4 and 5 may merely be held upon the inclined surface of the belt 13 on the side which is moving toward the rollers 4 and 5. rlhe belt 13 can comveniently be formed of live rubber, or some similar material and will present a suliciently frictional surface so that garments laid upon it will be carried up on this belt beneath the guard rollers 16, and then between the rollers 4 and 5. The presence of this belt 13 makes it unnecessary in most lll@ cases for the operator to maintain his hands on the garments after they'have First been laid upon the belt. In some cases, however, where the garments must be spread out or heldin a certain position before they are passed between the main rollers the hands of the operator must necessarily remain on the garment until it is quite close to the main rollers. To insure against carelessness which would cause the hands to be caught in the rollers 4 and 5 the guards 16 are provided, and should a hand be caught between this roller and the belt, the roller will give upwardly because of its resilient mounting, allowing the hand to be pulled away before it is caught by the main rolls. Of course, also, as soon as a hand touches a roller the operator will stop the machine in any event.

Not only does the present device provide a means which obivate the necessity for the operators holding the garment in most cases, but it providesfa guard which warns the operator before the hands have been caught between the main rollers. A further advantage is that the present device is so simple in its construction that it may be readily attached to wringers and similar machines which are already in use, and does not require to be built into the machine.

It will be understood that while I have described and illustrated my invention as applied to a wringer it may equally well be applied to an ironing machine or similar apparatus with but very slight modification.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed.

. I therefore particularly point out and distinctly claim as my invention An attachn'ient for a wringer comprising spaced frame members adapted to be engaged upon the vertical frame members of a wringer, a pair of rollers aiiljustably supported in the ends of said frame members. respectively, on opposite sides of said wringe'r, an endless belt mounted about said rollers, said belt being passed between the co-operative rollers of the wringer, a pair of vertically slidable rods mounted on said first-mentioned frame members on each side of and adjacent said wringer rollers, resilient elements on the lower ends of each of said rods, and guard rollers journaled respectively in the upper ends' of said rods in parallel relation with the wringer rollers and held in resilient contact with said endless belt.

Signed by me, this 12th day of April, 1921.

FRANK HREBEK.
