14 Claims. (Cl. FaS-79) This invention relates to sad irons and more particularly to a novel and unusually simple rest for supporting the bottom thereof above the ironing board when the iron is not being used.

Numerous attempts have been made heretofore to provide automatic as well as semi-automatic and manually operated rests for sad irons to avoid damage to fabrics being ironed when the iron is not being used. These have been unsatisfactory for various reasons. For eX- ample, many are complex and costly to incorporate in an iron. Others are unsightly and include mechanisms exteriorly of the iron which hinder the operator and catch in the material being ironed. Many are inconvenient to operate or involve control members encumbering the operating7 handle of the iron or which conduct heat thereto causing burns to the operator or, at best, discomfort.

The present invention provides an exceedingly simple automatic iron rest which is locked in a collapsed or retracted position at all times and under all operating manipulative movements except when the iron is tilted upwardly beyond a predetermined angle. when the iron is so tilted, the rest automatically extends to an iron supporting position. Retraction and relocking of the rest is accomplished merely by moving the iron forward, Although the rest includes two moving parts, these are held against movement except when moving into or out of the retracted position.

It is therefore a major object of the invention to provide a sad iron with a gravity actuated automatic rest for supporting the sole plate above the ironing surface.

A further object is to provide a gravity actuated rest having two very simple, inexpensive components arranged to occupy a minimum amount of normally unused space beneath the cover shell of an iron.

Another object of my invention is to provide an iron rest which automatically releases the rest for gravity extension when the iron is tilted upwardly beyond a predetermined angle.

It is also an object of the invention to provide a rest which can be collapsed easily and simply as well as one which is normally concealed and locked within the iron in all normal manipulative positions thereof including the carrying position frequently used when ironing.

Various other objects and advantages of my invention will become evident from the following description of two illustrative embodiments taken in connection with the accompanying drawings, wherein:

Figure 1 is a side view, partially in section, of one .embodiment of the invention, and showing the rest retracted position;

Figure 2 is a View showing the rest supporting the iron sole plate out of contact with the ironing surface.

Figure 3 is a fragmentary view along line 3 3 on Figure l;

Figure 4 is a side view of a second embodiment with the rest in retracted position; and

Figure 5 is a view showing the same rest in extended position.

The embodiment illustrated in Figures l to 3 is incorporated in a conventional type electric sad iron comprising a cast sole plate 16, having an embedded, resistance heater element 11 arranged in a U-shaped manner near the marginal edge of the plate. Overlying the sole plate is the usual cover shell 12, the rear end of which extends beyond the end of the sole plate, as shown in the drawing. This shell is secured to the sole plate by studs and screws in a well known manner. Overlying and secured to the cover shell, as by screws 16, is operating handle i3, having a front leg 14 and a rear leg 15. A temperature regulator dial 17 is located between the bases of the handle legs and is connected with a thermostat regulator of any desired design, housed within the cover shell and lying in heat exchanged relation with the sole plate.

The service cord is not illustrated, but it will be understood that it may be mounted in the far side of rear handle 15. The inner end of this cord extends downward into the rear end of the cover shell where it is connected in circuit with the heater element and the thermostatic control. Access to the terminals is had by removing detachable cover plate 18 closing the open rear end of the cover shell as clearly shown in Figure 1. The lower, rear corner of this cover plate is preferably located somewhat above the lower face of the sole plate.

The automatic rest comprises a strut member 2i) stamped from sheet stock. This rest is located preferably in an opening 2l along the longitudinal center line of the iron. Rest 2li is rotatably mounted on a pivot pin 22 secured to the opposite sides of slot 21 in any suitable manner as by peening over tabs 23 on the sole plate. The forward lighter end 24 of the strut has an upwardly and rearwardly inclined surface 25 for a purpose which will be explained below.

Overlying the strut is a tubular raceway 26 having a slot 27 along its lower side for receiving end 24 of strut 2li. The forward end Z8 of the raceway rests against the bottom of the sole plate, while the rear end 29 may be partially collapsed, as indicated. The raceway is supported in any suitable manner as by bracket 30 spotwelded to the interior of the cover shell.

Freely mounted in raceway 26 is a ball 31 which is preferably made of heavy material such as steel or lead and which has a diameter slightly less than the interior diameter of tube 26. This ball constitutes a gravity actuated control means for holding the rest in collapsed position or releasing it for movement to its extended position.

Operation When the iron is in the horizontal or normal operative position, the parts are in the positions shown in Figure 1. That is, ball 31 is in the lower end of tube 26, and rests in part against end 24 of the strut ,t0 hold the rest in its fully retracted position slightly above the lower surface of the sole plate. The operator may move the iron freely backward or forward, or lift the iron above the board without releasing strut 29. lt is not even necessary to hold the iron in a horizontal position when lifting it, or it is quite apparent that the iron ,can 'be tilted forwardly and backwardly to a Considerable angle without disturbing the position of control ball 3l.

Should the operator desire to support the iron in an inclined rest position, it is merely necessary to tilt the iron backwardly about the rear corner of ,cover plate 41S. As soon as the iron is tilted to a predetermined or critical angle-that is when surface `25 of the strut is inclined rearwardly in the opposite direction-.ball 3l will 4quickly roll to rear end 29 of the raceway. Since the rear end of strut 20 is considerable heavier than the forward end,

-of pivot pin 22.

the strut will immediately pivot clockwise by gravity action into the approximate position shown in Figure 2. The slight'sound made by the ball as it rolls along the raceway informs the operator that the rest has pivoted downward whereupon she tilts the iron forwardlyfonto strut 20. Y

Note that when the iron is in the inclined rest posi- V tion, the forward edge of the strut abuts the forward end of slot 21, which prevents further clockwise movement ofthe strut so that the sole p'late is firmly and securely supported in an inclined position above the ironing surface where it Vmay be left safely until the user desires to resume ironing. Note that when the iron is in its rest position, the rear half of raceway 26 is inclined slightly downwardly to the rear. As a consequence, ball 31 remains in the rear end of the raceway and out of contact with the strut.

To collapse the rest and resume ironing the operator vmerely grasps the handle and pushes the iron forwardly Second embodiment The second embodiment is generally similar to that described above, and differs primarily in that the race- .wayV for the ball is formed integrally with the collapsible rest. Accordingly, the Vsame or similar elements` are indicated by the same reference characters distinguished by a prime. Y

As clearly shown, strut 26 is carried by pivot pin 22 in the forward end of slot'21. Forward end 24' of the strut is bent to forma tubular raceway 26 for control ball Ydisplace the ball, and it is effective to hold the rest rmly .in place.

In this connection it would be understood that the weight of the ball is somewhat greaterrthan required to hold the rest in its collapsed position.

Operation Y' The second embodiment operates similarly to the arrangement illustrated in Figures l and 3. Thus, normally, the rest and the control ballare positioned to hold the rest collapsed. In this position, the user can move the iron freely in all directions as well as lift it fromrthe board without unlocking the rest. However, should she desire to support the iron with the sole plate off the ironing board, she merely tilts fthe iron backwardly about the real end ofthe cover shell until ball 31 rolls backwardly in raceway 262Y This causes Vthe rest to pivot in a clocltl wise direction, whereupon the iron may be lowered untill the end Vof the rest contacts the ironing board.

L Retraction of the rest isr accomplished merely by pushing the iron forwardly causing the rest to pivot counterclockwise andl ball 31 to roll back into the forward end Y of the raceway to lock the rest in its collapsed position.

It will be appreciated that the inclination of raceway 26 determines the angle at which the -rest is automatically extended. This angle may be varied over a considerable range to suit the convenience of the user. In general, the inclination of the raceway when the iron is in a horizontal position is slightly lessthan the angle to which the iron must be tilted to release therest. Obviously,

, Y 4 the greater the inclination of the raceway, the greater is the stability of the rest in the retracted position, and the less likelihood there is that the ball will become displaced during the ironing operation.

From the foregoing, it will be manifest that the present invention provides an exceedingly simple structure which is easily incorporated in existing iron designs. Moreover, the device functions automatically to extend a rest for the sole plate when one is desired, and to collapse the rest within the confines of the iron body when not needed. The rest is controlled by the simple expedient of tilting the iron to a predetermined angle to release a gravity responsive supporting strut and immediately allowing it to drop back onto this strut wherein it is supported in its inclined rest position. The retrac tion and securing of the rest are equally simple and involves merely pushing the iron forward.

As will be readily appreciated, the invention can be practiced by various arrangements of the essential parts other than those specifically described above. For example, the single strut shown might be replaced by a double strut operating in a pair of slots in the sole plate. As Va matter of fact, the rest will operate equally as well if supported to either side of the sole plate. Also a roller can be substituted for the ball. These and other variations will be understood as falling within the scope of the invention as dened by the following claims.
