3 Claims. l

` .My present invention has todo with ironing machines of the type commonly called mangles, employing a rotatable ironing roll and a pressing head.

In the use of such machines, it is necessary to dampen the garment or article being pressed, in order for it to iron smoothly. conventionally, thisis` done by the user wettingA the garment` and then rolling it up to allow the moistureto spread fully through the garmentafter which the garment is` unrolled and fed through the ironing machine. This procedure, however, isslow and tedious, requiring double handling of thearticles being pressed.

It is therefore an object of my present invention to render thisl conventional procedure unnecessary by simple, efcient and automatic means incorporated in the ironing machine for supplying moisture to the garment as it is fed into the machine.

More specically, it is an object to provide in such a machine means for generating steam and spraying it upon the garment as the latter is fed onto the roll. my invention also including, am`ong itsmore specific objects, novel and efllcient mechn anism for accomplishing this end. By way of` explaining my invention I shallnow describe one particular embodiment thereof which, however, is susceptible of modication within the limits of the appended claims. For this purpose I shall refer to the accompanying drawings, in which:

Fig. 1 is an end elevation showing the device in i ironing position;

Fig. 2 is an end elevation similar to Fig. 1 but showing the pressing head assembly swung away from the ironing roll;

Fig. 3 is a partial plan view;

Fig. 4 is a fragmentary View showing the ironing roll driving means; and

Fig. 5 is a fragmentary section taken on line 5-5 of Fig. 3.

Referring now to the drawings, the numeral 5 denotes a bed carrying spaced pairs of uprights 6, 'l and 8. A conventional ironing roll I5 is secured upon a shaft I5 journalled in the uprights 5, the shaft being power-drivenI by a motor I'l (Fig. 4), and drive connection I8.

A head assembly is carried by arm 28 secured to shaft 2 I, the shaft being journalled in uprights I and projecting outwardly from the uprights at one end, as shown at 2Ia, to receive a manual operating handle not shown, or conventional automatic power-driven means may be employed 2 torotate shaft 2I. By rotation ofthe shaft,y the arm 20 is` swung about the axis of the shaft.

` Secured to thearm 2 8 by pin 25` there is awater tank 28 having a pressure gauge G, and a filling plug 29 provided with a pressure relief valve 3.8..'

Secured to the front ofthe tank `by webs 3l, there is aL pressing head 35.l withinA which is mounted a conventional electric heating element` 3.1.

`As best shown in Fig. 5, the top side portion of the pressing headhas a bore providing a chamber 4.8 extending the width of the` pressinghead, from which `chamber aligned, relatively small discharge ports` 4I extend so as to discharge downwardly towards the ironing` roll. Water from the tank 28 is automatically suppliedto the chamber 4l!` by the` mechanism now to be described.

A pump cylinder 45 is secured by brackets 46 to an end ofthe tank, a piston 4'I` being mounted to reciprocate` in. the cylinder and being connectedby a rod. 48to a link 48. At its bottom end the, link is pivotally connected at 50 to the uprights 8.. Thus it will be seen that whenthe arm 28 isswung between the positions ofFgs. 1 and 2, the piston is caused to reciprocatein the cylinder. This movement of the arm takes place when the head `assembly is swung away from and thence towards the ironing rollin the course of insertinga fresh garmentbetween the ironing roll' and pressing head.

The cylinder has a port 5.2 in its top end pro-V viding a seat towards the cylinder for a spring'- loaded check valve 53. The port threadedly receives a closure plug 54 through which passes a conduit 55 leading into the tank. Thus on the upward movement of the piston in the cylinder, air under pressure is forced into the tank to force water therefrom through a pipe 51 leading to a valve 58, the valve in turn being connected into the chamber 40 by a tube 59.

The core of the valve 58 is rotated by a rod G8, the rod having an operating arm 62. On the outer end of the rod 60 there is secured another arm 63 to which is pivotally secured a clevis 65. A rod 61 has its top end projecting into the clevis and carries a cross pin 68 movable along slots 69 in the clevis, the bottom ends of the slots being closed to provide a' stop to limit outward movement of the rod. The rod is adapted toengage at its other end an arm 18 carried by the link I9. A spring 1| in the clevis urges the rod axially downwardly. A spring 12 around the rod and acting between rod ilange 'I3 and a bracket 'Il also urges the rod axially downwardly.

Thus when the head assembly is swung from the position of Fig. 2' to that of Fig. 1, or to the 3 left, the lower end of rod 61 is brought into engagement with arm 10, which pushes the rod aXially upwardly against the action of springs 12,

1I, which swings arm 63 and rotates valveactuating rod 60 to open valve 58 (see Fig. 5). This permits water under pressure in tank 28 to pass into :chamber 40. The heat created in chamber 4B by the heating element is suflicient to convertI the water in chamber-40 into steam,-

which passes `out through' the portsl to be discharged against a garment being inserted between the ironing roll and the pressing head.

A stop pin 'I5 is provided on the head sopthat if it is desired to render the valve 58 inoperative i and in closed position, the lever arm'62 is moved clockwise until the rod 60 is rotated suciently to bring the devis e5 against the 'stop ypin 15,'this action being allowed by the movement of the V.rod

liminary pressure in the tank for initial operation of the device.
