Y. application 'November 1s. 193s, Serna N0. scales 4 claim.. (caes-zc) This invention relates to pressing devices of the type known as smoothing or sad irons, and more particularly to such as are used in industrial establishments in the pressing of articles. such as clothing, etc.

The common variety oi' such irons are ordinarily heated upon a gas or electric stove, or bytheuseotgasinthebodyofthe iron. In such cases, it is often necessary to appLv moisture to the article being pressed, so as to enable' the operator to complete the operation satisfactorib.

'I'he present invention has as an object to provide a smoothing iron ofthe usual shape adapted for normal operation and provided with an internal heating means readily controllable with respect to its temperature and supplied from any convenient source-of electrical energy.

A further feature is in the provision of means whereby the article operated upon may be slightly moistened to a desired extent as the work progresses.' v

Another aim is to provide eiiective control means i'or emitting such moisture in the form of steam, the control means being readily actuated by an operator without removing the iron from the article while being pressed, or without the operator removing the hand from the handle of the iron.

A still furtherl purpose is to provide a simple, compact smoothing iron, readily operated and o! such weight and proportions as may be preferred.

These and other advantageous objects are accomplished by the novel construction, arrangement. and combination oi parts hereinafter described and shown in the accompanying drawings, forming an essential part oi' this disclosure, and in which:-

Stated in general terms, the iron consists oi a lower or base element, generally designated by the numeral 15, havingsecured on its upper side a cover element 16, having raised pads mounted by inturned handle supports 17 for a handle'18.

A removable section 16' of the cover element 16, is provided, the purpose of which will be described hereinafter.

studs 19 set in the base 1,5 to pass through the cover 16 and handle supports 17 which are clamped by nuts 20. Between the base and cover is a closed chamber 21 in which is disposed horizontally spaced metal plates 22-23, respectively upper and lower, the plate 23 having on its-lower side a liner 25 of 'mica or similar material; a similar lin'er '24 is seated in the bottom of the chamber 21.

These plates are held in their assembled position by reason oi' the studs 19, which pass through openings appropriately formed therein, while the margins oi the plates are adjacent to the walls of the chamber 21, vthese walls constituting the proille of the smoothing iron, which is oi'- the usual shape.

On the upper side of the plate 22 isfa sheet of asbestos 26, a similar sheet 27 being 'disposed midway in'the space between the metal plates 22-.23.

Set vin the rear portion oi' the cover element'16, and to one sidetnereot, is a dielectric block 28 containing a recess 29 in which are disposed

electric terminals

30 and 31. The terminal 30 engages a ilxed conductor 35, which is in electrical communication with a plurally coiled resistance 36 in the bottom oi' the chamber 21 between the liners :i4- 25.

Thus it will be seen that when the terminals v30-31 are in circuit, a current is passed through the resistance 36 in the bottom of the chamber, the heat being transferred to the base 15, and other parts oi' the iron.

of contacts 37, constituting a rheostat, from each of which extend taps 38 engaged by insulated screws provided with button heads 39, all of which are selectively engageable by a contact 40, carparts of the coil being on opposite sides of the sheet 27, the outlet end of the coil 45 having a connection 46 engaged with a downturned elbow 47setinthe base 15 andopentoatransverse e 48. which extends through the forward partofthesolidbaseoftheiron,itsendspro vided with closure plugs 49.

The pe 48 has communicating ducts 50 leading to a similar transverse passage 51, inthe rear portion of the base of the iron, which is also provided with plugs 49, to prevent the outlet, of steam or moisture.

The passages 48-51 are in communication with other ducts-52, closed at their rear ends and arranged convergently toward the front of the iron; the ducts 50 having plugs 53 at their outer rear ends.

Plugs 48' are disposed in the duct 48 adjacent the inner walls of the ducts 52 to force the steam or moisture rearwardly through the ducts 50,

` thence through duct 51 into the ducts 52.

The ducts 52 are provided with a plurality of lfine perforations 54 formed in the bottom wall of the base 15, for the escape ofsteam and moisture upon the surface of the material being op- 'erated upon with the iron.

Theinletend ofthecoil45isconnectedby a. raised coupling 56, with a bore 58 in an ini-eaching plug 57, extending from a block 60 and in whichisacheckvalve55toprev'entthereturn of water, the passage 59 being closed at its outer end by a screw plug 61. The screw plug 61 set in the rear portion of the block 60 carries on its inner enda rod 94, the top 95 of which is flattened, thus providing a narrow passage to insure a regulated ilow of water into the bore 58. IThe detachable cover plate 16', in the cover element 16, is provided so as to render ready access to these elements should such necessity arise.'

Theblockoissecuredon therearendofthe iron by bolts 62, which also serve as plugs for the passages 52, and has a transverse opening 63, controlled by a needle valve.64, the stem 69 0f. which passes upwardly through a boss 65, screw threaded to receive a nut 66. a lock nut 67 inter' vening. A

Setinthenut66isag 68tocompresspackingaboutthe stem69of theneedlevalve64,this stem being screw threaded at its upper portion A 70, and is guided by a sleeve 71 threaded into-an arm 72 extending from a bracket 73 iixed by the screw threaded boss on the block 60.

The sleeve 7l is provided with a head 74 and `a. check nut 75 by means of which the valve stem may be adjusted. A r,

A compression spring 76, abutting at its upper end the extremity of the sleeve '11, am to force' la collar 77, threaded on the stem 69 downwardly,

this collar being secured by a locknut 78.

Fixed in this collar, to extend oppositely out- -ward, are arms 79 adapted to engage the end .elements of a fork 80 integral with the rear end of a lever 61, pivoted at l82 on the bracket arm 72, this bracket being further provided with a forwardly extending arm 83 carrying an adiusting screw 84, provided with a lock nut 85 and ladapted to limit the depression of the lever 81,

the front end of which is provided with a knob Extending angularly from the block 69 is a tubular inlet connection 87 reduced at its outer end to receive a flexible tubo -89 connectedwith al water supply which, .from the foregoing, is ob' viously controlled by the needle valve 64.

- It is to'be noted in Eigure 5 that the outer tube inthecoil45passesthroughtherearwall ofthe iron into a chamber 90, formed in the lower part of the block 60, where itis provided with connections 91, including a check valve 92; also, another similar check valve `93 is disposed in the upper coil 45, as seen inl'flg. v8.

The usual guard 33. for receiving the electric cord plug, is provided on the rear handle support 17.

In operation, the lever 81 is depressed to allow a limited quantity of water to pass the end of the needle valve 64, into the e 59. past the first check valve 58, and into the heated tube 45, where, due to the high temperature of the tube coil, it is converted into steam to continue therethrough past the

check valves

92 and 93, into the ducts and out through perforations 54 onto the article being operated on.

- Upon release ofthe lever 81, the water is prevented from entering the heated tube coils, thus stopping the flow of steam from the perforations 54. The amount of steam for moistening the article operated on is very limited, usually for a period of but several seconds, after which the hot dry iron is used to complete the operation on that particular portion of the article being pressed. Therefore, itis imperative that the amount of water allowed to enter the heated coil departing from the scope of the claims hereto appended. Y

Having thus described the invention, what is claimed as new and desired to secure by Letters Patent', is:
