ber, from the space between said pads, and` from the garment or fabrics being pressed any steam, vapor, moisture or water thereon, said4 means being connected to operate conjointly with the device for applying steam to the garment or fabric for the pressing operation. More specifically the object of the invention isto provide an improved pressing machine `whose lower pressing member is so arranged that the operator can direct steam therefrom upon the garment 0r fabric or can withdraw through saidA member the steam, vapor or moisture.

A further object of the invention is to pro vide an improved pressing machine embodying means for applying steam to the garment and means for withdrawing the steam, vapor and moisture, said. two means being operable from the same controlling device, and preferably in such manner that either of said means can be rendered eifectiveywhen desired, the other means being simultaneously rendered ineffective.

Further objects of theinvention vare in part obvious and in part will appear more in detail hereinafter.

Referring to the drawings, Figure1 is a side elevation illustrating the application of the invention toone form of pressing machine; Fig. 2 is a .plan view, artly 1 n section on the line 2-2, Fig. 1; ig, 3 1s a detail section on the line 3 3, F1g. 2, showing the steaming valve; Fig. 4 a broken out'plan view of the lower pressing member; ldig.5 is a longitudinal section on the line 5 5, Fig. 4; and Flg. 6 is a cross section on the line 6-6, Fig. 4.-

, The inventionmay be ap lied to any desired form of pressing mac e, butmthe drawings, for purposes vof illustration, has been shown applied to a pressing machine of the general orm shown'in my prlor apf.

plication for pressing machine, filedv Aug. ,14, 1916, Serial No. 114,794. For clearness of illustration the main parts ofthe machine have been shown in dotted lines, the full lines representing the parts more immediately concerned in the present invention.

rlhe machine shown comprises a suitable frame 1 supporting the lower pressing member or bed 2 and having a swingingarm or lever 3 on which is located the coperating upper pressing member or head 4. Said two pressing members are moved toward and from each other for the pressing operation by swinging movement of said lever, as will be readily understood.

rlhe lower pressing member, shown in Figs. 4, 5 and 6, comprises a hollow body 5 having an inner steam heating chamber 6 supplied with steam from pipe 7 circulated through said chamber to the outlet pipe 8. The bed usually has a'slight turning movement on the frame to accommodate itself to the head, the axis of turning movement in this case being the axis of the pipes 7 and 8. Above chamber 6 is a horizontal wall 9 separating said chamber from a shallow space orchamber 10 between wall 9 and a-thin metal plate 11 having a large num ber of small perforations 12 and above which is the padding 13. Chamber 10 serves two purposes. First, itis a steam discharge chamber from which steam is supplied through the perforated plate and padding to the garment or fabric lying upon the bed, and, second, it serves as a vacuum chamber through which the steam,

vapor and moisture are withdrawn. For

these purposes it is connected both to a steam supply and to a source of vacuum.

The chamber 10 shown has 'a number of radiating or diverging ribs 14 to support plate 11. The channels between said ribs lead to one or two opennigs 15 communicating by lateral-passages 16 with apipe 17 connected to a pipe 18` extending downwardly to a suitable source of suction, such as the inlet side ofthe centrifugal pump 19 driven by a power source, for example,

the electricmotor 20. In pipe 18 is a suitable valve 21 having a Sliding valve stem 22 which opens theV valve when pulled outand Vcloses it whenpushed in. The motor and pump run ,constantly so that whenever valve -21 is open suction Vor vacuum ise'ective 1n and abutting a collar 39 on the valve stem.

chamber 10 and any steam, vapor or moisture on the garment or in the pads or the space between said pads is -withdrawn through chamber 10 and discharged through the pump. 23 indicates a pipe or conduit communicating by way of the valve 24 with the pipe 18 leading to the cavityv 10. This pipe 23 may communicate with any suitable source of steam supply, and in the drawings is shown as communicating with the live steam space or heating chamber 6. Valve-24 is provided with a rod 25 connected to a link 26 which is supported by a stationary rod 27, the valve 24 bein'g normally held closed by a spring 28.

The operating mechanism for the two

valves

21 and 24 is so arranged that either one may be opened to render either steam or vacuum effective in chamber 10, the arrangement being preferably such that when one valve is opened the other is closed and vice versa. As shown the operating mechanism comprises a bell crank lever having a foot treadle 29 and an arm 30 connected to a link 31 whose free end has a lateral proj-ection 32 surrounding steam valve stem 22 in advance of a collar 33 adjustable on said stem and secured thereon by a set screw 34. Collar 33 carries a depending weight 35, andas the valve stem is horizontal, said weight applies lateral bending movement to the valve stem suicient to prevent the valve from crawling from any position in which it may be and thereby disturbing its setting.

Link 31 is moved rearwardly (to the left in Fig. 1) by a spring 36 to open the vacuum valve. When said link is moved in the op .posit'e direction it first closes the vacuum valve and then compresses a spring 37 housed in' a chamber 38 of the projection 32 This construction provides lost motion between the linkand vacuum valve so that the iir's/t motion of the link may be utilized to close the vacuum valve and its further m0- tion to open the steam valve.

' link 31 which engages. an arm 41 on memhe may do so`by depressing ber 26 when the link is pulled forwardly by the bell crank lever. If the operator desires to apply steam to the padding or garment which closes the vacuum va ve 21 and opens the .valve 24, thereby permitting the passage of live steam from the space 6 through the pipe 23, .through the steam valve 24 to that part of the pipe line 18 which is above the valve 21. This valve'21 being-closed at' this' time, the steam rises through the pipe 1 8 to the chamber 10 and throu h the padding.,

The construction descri d is simple and i Jcanbe redilyapplied to any form of pressingmachine..` It puts both the steaming de.-

vice' and vacuum" attachment underthe con-Jl Said steam valve is opened-by a lateral 'projection ing Steam to the Space bers, means connecting said chamber to a'- the t'readle 29,

trol of the operator, who, by the operation of a single device can secure either effect at members and the space therebetween, and a single controlling device for both said means.

2. A pressing machine, comprising relatively movable pressing members, means for supplying steam to the space between said members, means for producing a How of air to remove stem and moisture from said members and the space therebetween, and means operable in one direction for render'- ing one of said means effective and in anot er direction for vrendering the other means effective.

3. 'A pressing machine, comprising relatively movable pressing members, means for supplying steam to the space between said members, means for producing a' flow of air to remove steam and moisture from said members and the space therebetween, an operating device having two positions for rendering either of said means elective, and yielding means normally maintaining said device in one of said positions.

4. A pressing machine, comprising relatively movable pressing members, means for supplying steam to the space between said members, means for producing a iiow of i air to remove steam and moisture from said and a single operating device or said valve.A
