This invention relates to pressing machines as garment and laundry pressmg machines,

movable toward and from the buck, the buck being mounted on a bracketor goose neck 3 and has for its object a particularly simple which in turn is mounted on a suitable frame and efficient means for evenly dampening a dry article or garment preliminary to pressing it without wetting or over dampen- The invention consists in the novel features and in the combinations and constructions hereinafter set forth 'andclaimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts I 'in all the views.

Figure 1. is a side elevation of one form of pressing machine embodying my invention.

Figure 2 is an enlarged fragmentary side elevation. r

Figure 3 is a front elevation of parts seen i in Figure 2, 'and also a sectional view of the manualcontrol means for operating the intermediate plate. v Figures 4: and 5 respectively are a fragmentary plan and edge views of the inter k mediate plate, the edge shown being one of the closed edges at the ends of the intermediate plate.

Figure 6 is a fragmentary detail view illustrating a section through-the intermediate I plate and the coupling between. the intermediate plate and" the conduit through which a cooling air current is conducted to said I v prpvlded with means as a valve 18 for conplate.

This pressing machine comprises upper and lower cooperating pressing elements, one of which is movable toward and from the other, means for dampening a garment as by projecting hot steam through the lower pressing element into the garment, a chilling plate movable into and out of position over the article on the lower pressing element to lightly and evenly condense the moisture in the garment preliminary to pressing it, means for actuating the movable element to close and open the press, and means for cooling the chilling plate.

I have illustrated my invention as embodied in a conventional 'type, ofpressing machine in which the cooperating pressingel'ements comprise a stationary buck 1 and a head 2' power actuated mechanism is used. That here illustrated includes a cylinder 7 having a piston rod 8 pivoted at 9 to the forwardly extending arm 10 of an angle lever pivoted at 11 at its angle and having an upwardly 1 extending arm 12 pivoted at 13 to the lower end of the link 14: which is pivoted at 15 to the rear arm of the yoke lever 5. The

parts

12 and 14 form-a toggle. The piston in the cylinder 7 is single acting.

The flow of'x'notive fluid to and from the cylinder 7 is controlled in any suitable manneras by push buttons and a release lever slmilarto those to be presently described, in connection with the means for operating the intermediate chilling plate.

.The press is locked in closed position by the pressure in the cylinder andis opened, when the pressure therein is released, by

springs

16 and 17.

The actuating mechanism and the control therefor form no part of this invention.

The lower pressing element or buck 1 is important only in connection with the chilling plate to be presently described.

The head 2 is also heated and is usually formed hollow in the ordinary n. inner to rece ve steam from any suitable-source.

. and is, supported by a movable carrier.

21 designates a chilling plate movable into the movement of the piston under the air and out of position overlying the. work on pressure is against the action of a returnthe buck 1. r This plate 21 is substantially ing spring 40 connected to the arm 36. COQXteIlSiVG Withthe buck 0f nt ex- The flow of air to and from the cylinder 33 tent to cover the-article being operated upon is controlled by any suitable manually, Dyerator-operated valve meansi' lhe valve means The carrier here illustrated consists of a h shown comprises a, v lv a i 41 c n,

pair of front and rear diverging rods 22, t d t one d to a, ip 42 leading to a 23 movable across each end of the buck- Th source of compressed air, a normally-closed plate 231s secured to the upper ends of rods ri g e d i t k valve 43 i th e ing, 22 n 23 at T 1 111 a anormally open exhaust valve 44, and a man healing Sleeve 2311 T bearmg Sleeve 23b ually controlled device as a push button 45 is Pivotally mounted on a P P j i g for operating the valves. V The valves 43 and from the frame of Pressing mavchlne- 44 are connected by a stem 46 so that they act 3 T lower ends of each P of rods 23 as a unit, and the casing is connected to the are secured to a shaft or stud 24 which moves li d 33 b a, ip 47 connected to the f vertically along a; stationary guide 25 se cured to the frame, theshaft 24 being also 7 a rock shaft so that the carrier and the plate 21 have a fore and aft movement as well as an up and down movement. It will be understood that there are a pair of

rods

23, 22, shaft 24 and guide 25'at each end ofthe buck.

The plate 21 is of metal and is formed hollow for receiving a cooling medium as air, and is preferably composed of top and'bottom sheets 26, 27, the sheets being spaced apart to form a passage for the cooling meo dium between them; The sheets are spaced 4m provide an inlet and an, outlet for the air,

the inlet being the pl ate. The cooling means is preferably arranged located at the rear edge -of to blow air through the plate and .cool the same only when the plate is in its open position as indicated by the dotted lines, Figure 2. This blowing means illustrated diagrammatically and comprises a blower having an outlet pipe 31 terminating in an exit slot at, 32 with which the-inlet edge of.

the plate '21 comes-into register when the plate isin open or inoperative position, that is, its position indicated by dotted 'llIlBS, Figure 2.

' The plat e 21 and the carrier theref or-jis preferably power ,operatedand as here illustrated, the means for actuating the plate comprises a; cylinder 33 having a piston movable therein, he rod 3 1 f which is connected C0"at '35 to one arm of a' lever 36 mounted on a casing between the valves. I

The motion of the push button is trans- .ferred to the valves through levers 48 and 49, the latter acting-on the stem 50 of the exhaust valve. Obviously, depression of the push button 45 will close the exhaust valve 44 and open the intake valve 43 permitting air to flow to the cylinder 33 and actuate the piston therein, and hence through the

levers

36, 38

and links 39 swing the

carrier arms

22, 23 above the axis of the studsor shaft 24 and at the same time, move the shaft 24verticallyin the" guides 25 thus in effect first swinging the plate 21 from its open dotted line position, Figure 2, over the buck and then down on the bucln Although 'this movement is-the re- 'sultant of two components, and the latter part of the movement downwardly takes place while the links 39'are swinging in the part of their arcs of movement A, by-far the predominating part of this last resultant movement is downward:

The valves 43, 44 are held in their operated position by suitable means as a diaphragm 51 in a diaphragm'chamber 52, the diaphragm acting on' a sliding stem 53 which actson one arm of the lever 49. The pressure side of the diaphragm chamber 52 is connected to the interior of the va1ve-casing 41 by a passage 54. As soonas the button 45 is depressed to close the exhaust valve 44, and open the intake 43-, the air'pressure will pass into the diaphragm chamber and act on thejlever 49 to hold the valves intheir operated posipart "of the,

tion, when the plate 21 is in its operative posi-'- Similar-push buttons control the-flow of motive'fluid to the main cylinder 7 and oper- "ate to bring the head 2 down on the plate 21,

and pres s thegarment; i

When the pressure in the diaphragm chamber -52 is released, the valves 43, 44 are free to return to their normal position, and

rock shaft 37, this rock shaft extending transthe a Q f li fIOm the, cylinder 33 1 8 011 versely-of the frame and havingro'ck arms 38 o g h plpe 47:; valve casing 41 and the on op o'site ends thereof which are connected exhaust passage 44 controlled bythe-exhaust by lin 39130 the studs or shafts 24. Thepis valve 44. The air is enhanstedfrom the dia 65 tonin the cylinder 33 is single acting, and phlagm chamber-by a normally closed exhaust valve 54 located in the valve casing 55 g and connected by a pipe 56 to the pressure side of the diaphragm chamber 52; the exhaust valve 55 being spring pressed and opened against the, action of the spring by. a releasei lever 57 acting on the stem of the exhaust valve 55. The release of the air in the cylinder 7 is controlled by a similar release lever 57, but as the operation of the actuating mechanism for the head forms no part of this invention, further description of the control of the flow of air to and from the cylinder 7 is unnecessary.

In operation, the operator lays a perfectly dry garment on the buck-1, depresses the button 45 to bring the plate 21 into position overlying thegarment on the buck, and then release lever 57 permitting the chilling plate 21 to return to its open position under the reaction of the spring 40. Thereafter, the

operator operates the machine to bring the hot head down onto the damp article to press 'therewith for projecting steam'through the and dry the same.

When the plate 21 is returned to its open position, indicated by the dotted lines, Figure 2, the air inlet on the rear edge thereof comes into registration with the outlet 32 of the air blowing pipe so that a cooling air current passes through the plate and cools the same for the next operation.

This machine is-partficularly advantageous in pressing dry laundry or newly manufactured garments as shirts and the like, which are made from clean cloth and have not been laundered. In other words, it is particularly advantageous for garment manufacturers as well as for other users where the garfnent comes to the pressers perfectly dry.
