' 20 Claims.-

The present invention relates to an ironing device which is manually guided and operates automatically.

It is an object of this invention to mount a sad iron so tht it may be movable with ironing pressure on an ironing board in any direction and which is supported and maintained at the released position above the ironing board when the operator's hand has released the handle of the iron.

It is a. further object of the invention to so construct the mechanism in the handle and guiding parts of the iron to apply an ironing pressure or force by the weight of the operators hand and; arm as the operator guides the iron over the ma'-- terial to be ironed.

A still further object of-the invention resides in the lever action in which the weight of the operator's hand and arm or hand alone is multi-- plied into a force sufficient to produce an ironing pressure on the material to be ironed.

Another object of the invention is to provide a brake device in the arm of the ironso that the iron and arm will remain in the position above the ironing board where released by the operator and to automatically render the brake effective and non-effective dependent upon the vertical position of the iron relative to the arm.

Further objects will be apparent from the following description taken in connection with the accompanying drawings in which:

The ironing device is provided with any type of sad iron 3| suitably heated by an electriccurrent and having a hollow post 32, 1 n-handlebrac'ke'tfl 4, Figs. 1, 2, 5 and 6. is secured tothe post 32 at the top .33 by a suitable rivet or'screw,'not shown. a

A' handle'o'r grip member lof'any suitable ma: terial is pivotally mounted on the handle bracket 4' by means of a pin ithrough the intermediary of ahandle lever 2, Figs. 1, 2,7, and 8, pivotally mounted on the pin 5 and secured to the handle I by means of a screw 3. An actuating'lever I, Figs. 1, 2, 11 and 12- is pivotally'mounted in the handle bracket 4 by means of a'pin to having. one and connected bya pin 8 to one end of a connecting link 6.. Figs. 1, 2, 9 and 10. The other end of the connecting link 6 is connected to the handle lever 2 by means oi a pin 1 and the other end of the actuating lever B is connected, by means of pins 34, to a pair of upstanding-lugs,

35 mounted on a bearing in the member-3t of" 0 the articulated arm 31 as for instance shown in Patent No. 2,231,896 of Feb. 18, 1941. Thus, the iron may be rotated 360 on the arm 31. A safety pin type of spring II is mounted on pm It and has one end l3 bearing against the bracket 4 connected to an ironing board by means of a spindle 2| forming a rotary connection. This arm 3'! permits the iron 3| to be moved over an ironing board in all horizontal directions,

The arm 31 is provided with. an automatic brake :or friction device, Figs. 1 to 4, which is adapted to hold the arm andiron in any released position above the ironing board to Prevent-the iron and arm from swinging, 'if,.f or instance, the ironing board" 40 is not exactly horizontal. The brake device is automatically released when the further the iron 3| may even be moved together withthe armin the raised position bylmereiy overcoming the friction of the brake. The brake device comprises two parts 4 ahdl'l, Figs. 3. 4,, v 17 and 18, of which the forward brake lever It section taken on line and the other end 30 against the lever 8 to couniron 3| is forced down on the ironing board and is pivotally mounted on a pin IS in the arm section 36. The rear brake lever ll is pivoted by means of a pin It! on the arm section 38 and as seen in Figs. 17 and 18, both arm section 38 and lever H are U-shaped, but the lever fits over the arm section 38, whereas the arm section 36 and lever l4 are also U-shaped but the lever I4 is in its arm section.

The lever Figs. 3 and 4 is provided at one end with a circular fiat ring section 4| and at the other end with a friction block IS. The lever I1 is also provided at one end with a circular flat ring section 42 and at the other end with a friction block IS in a short projecting lug 43. The friction block |6 cooperates with the ring 42 and the friction block |9 cooperates with a stationary disk 20 secured to the top of the stationary spindle 2| by means of a screw 44.

The electric cord or cords 45 enters the iron through the protecting conduit or tube 46, Figs. 15 and 16, and passes along the web 41 of the handle bracket 4 into the top end of the post 32 and through the latter to the heating units (not shown) in the iron. A thermostat dial 23, which is adjustable, cooperates with a pointer 50 forming apart of the plate 48 which is secured to the bracket handle 4 bymeans of a screw 49. The thermostat adjusting device for heat regulation and cut-off of electric current when the iron istoo hot is well known and therefore needs no further explanations.

' The ironing device operates'as follows:

In the position of the iron 3| in Fig. 2 the parts are shown in the inoperative or non-ironiron while counterbalancing, and to eliminate any high bearing pressures. When the iron 3| contacts the ironing board 40 the weight of the operators hand and forearm on the handle I will exert an ironing pressure through the connecting link 6, actuating lever B, lugs '35 and articulated arm 31 to'the' ironing board 40 which will thus force the iron 3| on the board through the handle bracket 4 and post 32. A pressure or weight of the operators hand and arm of approximately three. pounds will exert an ironing force of approximately twenty pounds. In the position of Fig. 1 the brake or friction device is inoperative so that the arm 31 may be articulated to permit the movement of the iron in any direction on the board..

The brakedevice, Figs. 1 to 4, automatically locks the elbow joint 5| and the pivot joint 52 when the iron is in its lifted position, Fig. 2, by the action of the spring The top 53 of the iron 3| presses against the ring 4|, due to the lift of the spring II. This forces the lever l4 slightly clockwise around the pin l5, Figs. 1 and 2, whereby the brake block [6 will frictionally contact the ring 42 of the lever I! to lock the elbow joint 5|. Pressure of the block l6 will force the lever ll slightly clockwise around the pin I8 I to frictionally contact the brake block I9 against the disk 20 secured on the spindle 2| by means of the screw 44, thereby locking the joint 52 by the force of said block l9 against the disk 20. This prevents the arm 31 as well as the iron 3| from wandering or rotating from the released position as the iron 3| is held in place relative to the arm 36 by means of the ring 4|, Fig. 2 which is a metal to metal contact. As soon as the operator pushes the handle and iron slightly downward, this brake or friction action is automatically and immediately released and remains inoperative as long as the iron is in contact with the material to be ironed, since the spring is inoperative on the brake device.

The brake blocks l6. and [9 are suitably secured on' the levers I4 and Il respectively by means of receiving cups into which the blocks are pressed and are made of any suitable material such as leather, impregnated fabric, etc.

The parts 2, 4, 6, 8, l4 and I! may be suitably made by stamping and pressing these parts into shape with webs connecting the two parallel sides of each part. As these parts are shown in detail on the drawings the connecting pins are also shown and indicated.

It is, of course, understood that the various parts may be modified and thus the exact showing of the details does not necessarily limit the invention to such exact constructions.
