To all 'whom t may concern:

Be it known that I, EvnRETT E. PARKER, citizen of thevUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pressing Machines, of which the following isa specification.

This invention relates to pressing machines and more particularly to machines for pressing garments, although capable of use for pressin fabrics of any kind.

The object o the invention is to provide an improved machine which withdraws -the steam, moistureland water of condensation from the garment and from the fabric pads of the pressing members and thereby reduces the tendency of the pads to retain moisture, which more quickly dries the garment and prevents puckering of the seams, as would 'be the case if4 the moisture were allowed lto evaporateslowly which accelerates the pressing o eration and enables the garment torbe safe y put on and worn imv mediate'ly after pressing; and which also prevents escape of steam and vapor into the room. A further object of the invention is .to provide a machine of this kind in which the application of suction or vacuum for withdrawing the steam and moisture is automatically controlled and requires no special attention or operation by the operator, but iscaused or controlled by the normal operation ofl the machine itself so that said suction is effective at the proper and no other times.

Further objects of the invention are in part obvious and in partwill appear more in detail hereinafter.

In the drawings, which represent one em bodiment of the invention, Fig. 1 is a side elevation showing the head elevated. Fig.

2 is a front elevation, partly in section,l

showing the head depressed. Fi 3 is a plan view of the up er' portion o the ma. chine; Fig. 4 is a dltail sectional view of the head on the line 4 4, Fig. 3; Fig. 5 is a detail section on the line 5 5, Fig. l; and Fi'g. 6 isa detail sectional view, on a larger scale, of the steaming valve, and Fig, 7 is a side elevation, showing a modification.

The machine shown in the drawings comprises a suitable frame 1 near the front of which is located 'a column 2 supporting the lower pressing, member or buck 3 and which is of common form, being provided with a hollow heating chamber 4 connected to a suitable source of steam supply, such as the pipe 4". The upper wall 5 of the heating chamber separates it from a steaming cham-v ber 6 having a perforated up er plate 7 on which is laid the padding 8. team may be admitted to said chamber 6 and discharged through the perforated plate 7 and distributed over and across the'garment lying on the padding 'by opening a valve 9 controlling one or more ports in the wall 10 between said chambers, said valve being operated by Ya rod 11 connected to a foot treadle 12 and being normally held to its seat by a spring 13.

At the back of the frame is a column 14 forming a support for the lever 15, one arm ofwhich carries the upper pressing member or head 16 balanced by a weight 17 on the otherarm. The head may be advanced or depressed` into pressing relation with thel buck by any suitable operating mechanism,

the drawings showing for this urpose two toggle links 18 connected by a ink 19 to a lever 20 ivoted in the frame and connected by a lin 21 to the foot treadle 22. The head is normally held elevated by the usual tension spring or springs 23.

The head is of substantially the same form as the buck, being provlded with a heating chamber 24 communicating with a suitable source of steam supply such as the inlet and outlet pipes 25, 26 which are provided with swivel'joints 27 on the axis of turning movement of the lever 15. The bottom\wall 28 of the heating chamber is also the upper wall of a separate suction chamber 29 having a bottom perforated plate 30 to which the padding 31 is applied. This chamber 29 communicates with a pipe 32 which may be connected by branches to both as the fan or blower 35. i When thevalve is Y opened suction is elective in the chamber 29 and draws into said chamber and out to the exhaust any steam or vapor between the head and 'buck or any moisture or vapor in. or on the garment or the pads of the press# los 'ing members. Said valve is preferably opened only when the steam supply is on or moisture is present. It may be operated by hand, if desired, but preferably is controlled or operated automatically so that the -suction is made effective whenever steam is supplied to the garment, thereby doing away with the necessity or the operator manipulating a separate device for producing the suction effect. Said valve may lbe controlled or operated by either the steam supply controlling devices or b the mechanism for o eratlngl the movab e press head. It is s own as provided with a valve rod 36 connected by a clevis 37 to an arm 38 on one end of a shaft 39 whose opposite end has an arm 40 with a toe 4l lymg beneath the foot treadle 22. A tension spring 42 normally holds the valve closed. v

In the upper position of the treadle 22 it is above the toe 41 and during the early downward movement of the treadle to bring the head down to the garment on the buck said treadle has no effect upon the vacuum valve. During the nal motion of the treaclle, however, it engages the toe 41 and turns shaft 39, thereby opening the vacuum valve. Any steam which may be supplied to the garment or any .moisture on the garment or padding is quickly withdrawn by the suction pump, thereby keeping the pads dry and drying the garment quickly before it puckers at the seams and with the best pressing results. The garment may be safely put on and wor'n immediately after pressing. Moreover the steam and moisture do not escape to the atmosphere and will not affect the health of the operator or injure the walls or furniture in the room. When the head operating lever is released and moves upwardly the vacuum valve closes and cuts olf the suction without requiring any attention b the operator. The vacuum is therefore e ective for short intervals when the flashes of steam are turned upon the garment and. does not aect the heating of the pressing head bythe steam supply to its heating chamber as will be readily understood.

Fig. 7 shows a modified form of the invention in which the vacuum valve is operated by one ont the toggle links linstead of by the pressure treadle. The pipe 43 communicates throughl the edge ont the head with the vacuum chamber therein. Said pipe may be a flexible metallic hose leading directly to the vacuum valve but is shown as passing toa swivel joint 44 on the axis of swinging movement of the head. carrying lever, thence to the vacuum valve'45- and thence to the pump or fan 35. The valve has van operatin handle 46 normally moved to the position shown in dotted lines by a sprin 47. When the press is opened one of t e toggle links connected moines to the pivot 48 engages a toe 4`9 on the valve handle and turns it to the position shown in ull lines, thereby closing the valve 45, whereby the suction becomes in.- effective. When the -press is closed the handle 46' is released and spring 47 opens the valve.

What I claim is:

A pressing machine, .comprisin relatively movable pressing members, eac provided with a foraminons pressing wall and an inner chamber communicating with the atmosphere through the openings in said wall, means for supplying steam to the chamber in one of said members, means for producing suction in the chamber in the other member, means for producinv relative pressing movement between sai members, and means actuated by said membermoving means for rendering said suction soA Sliv

effective when said members are .in pressing relation witheach other.

2. In a pressing machine, a buck having a steam heated chamber and a steam 'distributing chamber, the latter chamber having an outlet for applying steam to a arment on the buck, means for control 'ng the entrance of steam to the distributing chamber, and means movable about an axis at the rearof the buck and to and from the surface thereof wherebx air may be caused to How over said sur ace and a garment thereon.

3. Ai pressing machine, comprisin relatively movable pressing members, eac provided with a foraminous pressing wall and an inner chamber communicating with the latmosphere through the openings in said wall, means for supplying steamto the chamber in one of said members, means for producing suction in the chamber in the, other member, means for producing relative pressing movement between said members, and means actuated by said member-moving means for rendering said suction effective only when said members are in, pressing relation with each other.

4. In a pressing machine, a buck having a steam heated chamber and a steam d istributing chamber, the latter-chamber having an outlet for applying steam to a rment on. the buck, means for control 'ng the entrance of steam to the distributing chamber, and a hollow member movable about an axis at the rear of the buck to and from the surface thereof and through which air may be caused toilow over said surface and a garment thereon.
