24 Claims.

This invention relates to improvements in pressing machines of the'type generally used in laundries and particularly to a pressing machine having superposed upper and lower ironing units which coact so as to be simultaneously utilized by one operator.

An object of this invention is to provide a pressing machine having upper and lower ironing units, comprising a swingable upper ironing element, a fixed intermediate element and a swingable lower ironing element and automatic means for swinging the lower element forwardly and upwardly to a predetermined loading position when the upper ironing element is swung down into ironing position.

Another object of this invention is to provide a pressing machine having upper and lower ironing units, comprising a movable upper ironing element, a fixed intermediate element and a movable lower ironing element and automatic means for moving the lower element forwardly to a predetermined loading position in timed relation with the upper ironing element when said element is swung down into ironing position.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed outin the claims which form'part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:

Figure 1 is a front elevation of a pressing machine embodying my invention.

Figure 2 is an end elevation with one of the side frames removed.

Figure 3 is an end vew of a modified pressing machine.

Figure 4 is a diagrammatic end view of the pressing machine with the upper pressing unit in open position ready for loading.

Figure 5 is a diagrammatic end view of the pressing machine'with the upper pressing unit in a closed position and the lower unit in an open position ready for loading.

In the illustrated embodiment of the inve tion, Figures 1 and 2 show a pressing machine of the type generally used in laundries, and comprising a closed-side frame l having uprights H, H united rearwardly by a cross-head l2 which terminates in bearings l3, l3.

Levers M are fulcrumed on pins I in the bearings l3 and carry at one of their respective ends an ironing element 16 having a polished ironing head l1. The opposite ends of the levers 14 have apertures l8 serving to receive and connect two elongated coil springs IS with ears 20 extending from the frame 10. The frame 10 supports an ironing member or buck 21 having a work supporting upper padded surfaceor bed 22 which jointly with the head l1 forms an upper ironing unit 23. The buck 2| is fixed to the uprights l l of the frame ID in any suitable manner, such as by means of bolts 30. I

The means for swinging the head 11 into and out of pressing engagement with the work supporting surface 22 consists of a cylinder and piston motor means 24, the piston rod 25 of which is connected to the lever Id at a point 26.

Outward movement of the piston in the cylinder of the motor means 24 swings the head 11 downwardly about the pivot into pressure engagement with the work supporting surface 22. This motion is accomplished by fluid pressure through a line 21, controlled by a hand operated control valve 28, shown in Figure 5, wherein the upper ironing unit 23 is shown in pressing position.

It is to be noted that the lower portion of the motor means 24 is pivotally secured at 16 to an angular lever 1| having a straight slot 12 and which is pivoted in a frame 14 on a pin 13. The frame 14 has curved slots 15 on opposite sides. The lower end of the arm 49 has a pivot 16 in engagement with the slot 15.

' When the motor means 24 has motive fluid applied thereto the rod 25 moves upwardly until the head 11 is in pressing engagement with the bed 22. The cylinder 24 then moves downwardly with the angular lever 1| to a position shown in dotted lines carrying pivot 16 and arm 49 into lower position as shownin 11 and causing an increase leverage pressure against the bed 22 for ironing.

Movement of the head 11 out of pressing engagement with the work supporting surface 22 is accomplished when the fluid pressure is allowed to exhaust from the cylinder of the motor means 24 permitting the head 11 to be'raised by the spring 1.9.

Fixed to the uprights ll of th frame 10 by bolts 31 is an ironing element 32 having a polished ironing head 33. The head 33 may be in vertical alinement with the buck 2|. An ironing element 35 having an upper pressing bed or work supporting padded surface 35 is slidably mounted in arcuate slots 31 in the frame uprights l I. The slots extend forwardly and upwardly to a position considerably in front of the normal pressing position of the ironing head (-33. The ironing element has a lower plate 33 from both ends of which extend two circular projections 39 which are slidable in the slots 37 and by means of which the ironing element may be moved to a position in alinement with the head 33. The padded supporting surface 35 and the head 33 jointly form a lower ironing unit as.

Means for moving the ironing element 35 forwardly to a position well in front of the normal pressing position comprises levers it fulcrumed at their lower ends on pivots in the uprights l l. The upper ends of the levers it have apertures t6 adapted to receive circular projections d1 extending from opposite end of the plate 38 of the ironing element 35. The aperture 46 has a triangular upper end which permits contacting relation with the projecting member ll both when the bed 36 is in registering relation with the head 33 or out of registering relation with said head, as shown in dot-and-dash lines in Figure 2.

Coil springs 48 mounted on the pivots 55 have their ends in engagement in any suitable manner (not shown) with the pivots 4 5 and the levers 54 respectively and serve to force the levers forwardly.

In the position shown in Figur 2, the aperture 453 has a vertical wall which contacts the projection 4? and serves for moving the ironing member 35 in the direction of its forward and upward position shown in dot-and-dash lines.

Figures 2 and 4 show the upper pressing unit 23 in loading position and the lower pressing unit 53 in pressing position. The operator places an article to be ironed on the Work supporting surface or bed 22 and actuates the valve 23 and admits motive fluid into th pipe 27 and the motor means 2 1. Actuation of the motor 2d causes the forward portion of the lever M to move down with the ironing head I? and causes a gooseneck lever iil connectedto the ironing element l6 to swing forwardly at its lower end and to swing a pivotally connected lever 59 forwardly. The forward movement of the lever 5d actuates valve arm 52!, link 52 and handle El, which latter opens to exhaust, in valve mechanism 66, the fluid-pressure pipe from the motor means iidand 54. This causes the ironing element 35 to drop due to its own weight to the bottom of the slot 31 and permits the springs 68, (it to swing the arms id and the ironing element 35 forwardly and upwardly to the loading position shown in Figure 5.

Figure 5 shows the lower pressing unit in loading position and the upper pressing unit in pressing position. The operator places an article to be ironed on the work supporting surface or bed at and actuates a lever 55 on th control valve 28 and permits the motive fluid to exhaust from the pipe 27 and from the motor means 2 The springs it) now pull down one end of the rotatable lever is and thereby raise the head E; on the other end of said lever. The lever M is thereby moved rearwardly 'at its lower end, which arm in turn swings the connected arm 56 rear The latter moves link 52 to operat valve (it which admits wardly and actuates the arm 55.

motive fluid into the motor means 55, causing the arm as to be swung rearwardly to move the lower ironing element35 into alinement with the lower head draws link 52 backward, arm 5i closes a'valve mechanism' (not shown) in the separate fluid pressure line leading to motor means 53. The

At the same time that arm 52 arms 44 have pivotally mounted pins 56 projecting outwardly therefrom and when the arms swing rearwardly, the pins strike the last men-- tioned mechanism to open the same thereby causing motive fluid to enter into the motor means 53. The latter fills with said fiuid and then begins to raise the ironing element 35, which has gotten into alinement with head 33 into pressing engagement therewith.

By disconnecting the arm 50 from the lever &9 it is possible to operate the upper and lower ironing units 23 and 23 separately and independently of each other. The upper ironing unit is then operated solely by th upper valve 28 and the lower ironing unit is then operated solely by the lower valve 556. of the upper pressing unit 23 valves 89 and ill are respectively operated. There is provided a hole in frame H matching a similar hole in arm 44 to provide for inserting a pin as shown at 83 to be inserted for locking the arms 46 against movement and holding the bed 33 away from the operator when not in use.

Figure 3 shows a modified pressing machine having an upper ironing unit 6!] and a lower ironing unit 33 in superposed relation in a frame 62 positioned on the outside of the frame iii. The upper ironing unit 68 comprises a fixed head 63 and a vertically movable bed fi l which is actuated up and down by a cylinder and piston motor means 65. The lower ironing unit 53 is identical with that shown in Figures 1 to 4 inclusive.

Many other modifications may be made in the relative movements of the upper head and buck and as well as the lower buck, but the lower head remains substantially stationary to accomplish the utility and purpose of the invention.
