ELECTRIC FLATIRN ASSEIVIBLY Neil G. Herman, Pomona, Calif., assigner to General Electric Company, a corporation of New York The present invention relates to electric flatirons and particularly to the structure whereby the soleplate, the cover and the handle are attached to each other.

The object of the invention is to provide an improved construction and arrangement for fastening together the soleplate, the cover and the handle of a ilatiron which is simple in structure and gives firm connection between the cover and the soleplate; and one wherein the cover is attached to the soleplate by relative movement of the cover with respect to the soleplate whereby the cover may be quickly and easily attached to and removed from the soleplate.

The invention is well adapted for use in steam atirons and has advantages from an assembling standpoint when used in such tlatirons. For this reason the invention is specifically illustrated and described as embodied in a steam ilatiron, However, it is to be understood that the invention is not limited to use in steam flatrons but may be used in other types.

According to the invention the handle and the cover are connected together to form a unit and the unit is attached to the soleplate through the intermediary of front and rear brackets on the soleplate, the cover having means which interlocks with the front bracket by rearward movement of the cover with respect to the soleplate and the cover having means which interlocks with the rear bracket by downward movement of the cover with respect to the rear end of the soleplate.

Fig. 2 is a detailed top plan view of the front end of the tiatiron, the cover being in part broken away to show parts beneath it.

Fig. 3 is an elevation of the rear end of the ilatiron with parts broken away to illustrate structure inside the cover.

Fig. 4 is a perspective view of a front bracket used in attaching the front end of the cover to the soleplate.

Referring to the drawing, 1 indicates the soleplate, 2 the heating unit embedded therein, 3 the cover, and 4 the handle of the llatiron. At the forward end of the soleplate are walls which define a steam generating chamber 5 over which is fastened by a cover plate 6 by a plurality of spaced studs, one of which is shown at 6 in Fig. 1. Fixed in an opening in cover plate 6 is a steam dome 7. Fixed in the top wall of dome 7 is a valve body 8 having an orifice 9 through which water is supplied to chamber 5 from a water reservoir 10 through openings 1 1 in the valve body. Flow of water from reservoir 10 through orice 9 to steam generating chamber 5 is controlled by a valve head 12 on the lower end of a valve stem 13 which seats against a valve seat at the inlet side of orifice 9. On the lower end of stem 13 is a pin 14 which slides through orifice 9 to keep the orifice clean and open.

Handle 4 is supported on cover 3 by front and rear hollow posts 15 and 16, the lower ends of the posts hav- Patented July 24, 1956 ing integral therewith a base bar 17 which is seated on the top wall of cover 3 and is attached to it by a plurality of spaced screws, one of which is shown at 13 in Fig. 1. Connected to the top wall of water reservoir 10 is a lling tube 19 which projects up through an opening 19a in the top wall of cover 3 into post 15. Filling tube 19 is closed at its upper end and is provided with a front side opening with which is connected a filling sleeve 2l) which extends through the front wall of post 15. Suitable spring means is provided for biasing valve stem 13 toward open position, it. comprising a spring 20a positioned between the top wall of tube 19 and a collar on stern 13 as shown clearly in Fig. 1. The stem is moved by a knob 21 at the uppern end of post 15 provided with an arm 21a the inner endof which rests on top of stem 13. In Fig. 1, the valve isshown in open position, it being held open by spring 20a.: It may be closed by pressing down on knob 21; and held closed by moving knob 21 backward somewhat tor bring a shoulder 2121 on the knob under a ledge 21C' at the rear side of opening through post 15. Also 1o-v cated in post 15 is a thermostat adjusting control shaft. 22 to the upper end of which is connected a control. lever 23 by means of a slot in the control lever througl'r which the upper end of control shaft 22 extends with al loose fit. Control lever 23 extends out through a slot'. in the upper forward wall of post 15 and has an operat ing knob 24 on its outer end. In'the slot is a spring plate: 24a which serves to hold control lever 23 in place in frictional engagement with the bottom wall of the slot4 through which it passes. At 24h is a dial plate which: snaps over the forward upper end of post 15 and has suitable indicia thereon for indicating the setting of control lever 23. The lower end of control shaft 22 extends through a duct across reservoir 16 formed by a tube 25 to a position between the bottom wall of the reservoir and the top surface of the soleplate and at its lower end is suitably connected to a thermostat adjusting cam disk 26 pivotally mounted on a thermostat frame or bracket 27. Engaging the top cam surface of disk 26 is a thermostat adjusting arm 28. At 29 is the bimetal of the thermostat.

The specific structure of water control valve and the means for operating it and the thermostat structure and the means for adjusting it form no part ofthe present invention. The constructions indicated are similar to those disclosed in my application Serial No. 452,911, led August 30, 1954, assigned to the same assignee as the instant application. My invention has to do with they structure and arrangement for attaching the cover-handle assembly to the soleplate of the atiron.

For attaching the front end of the cover handle assembly to the soleplate there is provided a bracket 30 having an ear 31 at its lower end which is attached to the soleplate in the present instance by the one stud 6 which serves also for fastening in place the cover plate 6. In ear 31 is a depression which forms a beadv 32 which is positioned in a depression in plate 6 and serves to hold the bracket from turning on stud 6 as a pivot.4 Bracket 3l) extends up through a space between the front wall of cover 3 and the adjacent wall of reservoir 10 to a position where its end extends through and beyond opening 19a; and means are provided for interengagement between the upper end of the bracket and the wall of cover 3 at the Vforward edgeof the opening of achar-y acter such that the cover may be interengaged with they upper end of the bracket by a rearward sliding movement of the cover with respect thereto. In the present instance the interengaging parts comprise notches 33,011` opposite sides .of bracket 30 into which .fit the side walls of a recess 34 in the front edgeof opening 19a.l

For attaching the rear end of the cover-handle; asf

sembly to the soleplate there is provided holding means with which the cover may be engaged by a downward movement of the cover with respect to the soleplate. The holding means illustrated comprises a pair of spaced spring arms 35 which are attached to the soleplate at its rear end, project upwardly through an opening 36 at the rear of the top wall of the cover and are provided with walls which define shoulders 37 which engage over the 'top wall of the cover at opposite sides of opening 36 as shown clearly at 38 in Fig, 3, the arms being biased to such positions by their inherent resiliency. The spring arms are attached to the soleplate through the intermediary of a cross bar 39 with the edge of which the arms are integral, the cross bar being fastened to the soleplate by a screw 40. In substance the arms and cross bar form a U-shaped bracket the base of which is fastened to the soleplate. Above shoulders 37, arms 35 are-bent inwardly to provide sloping ends 41 down which the side edges of opening 36 may ride to spring the arms inwardly toward each other so that the edges may be brought to a position below shoulders 37 and the arms may spring out to bring the shoulders over the walls at the edges of the opening.

The rear wall of post 16 is provided with an opening 42 to give access to flatiron terminals, one of which is shown at 43 in Fig. 3, which project up through opening 36 and have attached to them the wires 44 of the flatiron cord set, the opening being closed by a cover 45 fastened in position by a screw 46. Cover plate 4S is utilized for locking the cover-handle assembly in place on the soleplate. To this end cover plate 45 is provided with inwardly projecting abutments or stops 47 which stand against the inner sides of arms 35 to hold shoulders 37 in cover locking position. In this connection it will be noted that arms 35 are biased toward the side edges of opening 36, i. e., transversely with respect to the heel of the flatiron. With this arrangement they may be locked over the side edges of opening 36 by simple inwardly projecting parts on cover plate 45.

At the rear or heel end of the atiron, cover 3 projects beyond the rear edge of the soleplate to provide a heel rest 48 which in cooperation with the top rear portion ofpost 16 forms a rest upon which the flatiron may be supported in an upended position. The space between the rear end of soleplate 1 and the heel rest 48 is closed by a plate 49 fastened to a flange 50 on the edge of the cross bar 39.

At its rear end water reservoir is supported on ledges 51 on arms 35; at its forward end it is supported on the soleplate through intermediary of the dome 7.

The rear end of cover 3 is supported in spaced relation to the soleplate by lugs 52 on the soleplate at its rear end.

In assembling the flatiron, the bracket 30, the spring arms 35, the water reservoir 10, the thermostat structure, valve stem 13 and control lever 22 are assembled on the soleplate; cover 3 and handle 4 are connected together by screws 18 and with the cover-handle assembly inverted, knob 21 and arm 21a are put in place. The knob 21 can then be held in place with the iingers while the control lever 23 and the spring plate 24a are put into the handle slot. The cover-handle assembly is then put down over the soleplate assembly, the upper end of control shaft 22 being guided by suitable means into the slot in the inner end of lever 23. Now with the cover-handle assembly tilted up somewhat at the rear, the side walls of recess 34 may be brought into notches 33 by a rearward movement of the cover-handle assembly with respect to the soleplate after which the rear end of the cover-handle assembly may be pushed down on to the soleplate, the side edges of opening 36 sliding down sloping ends 41 to force the spring arms 35 toward each other, to a position beyond shoulders 37 whereupon the arms will spring outwardly to bring the shoulders over the side walls ofthe opening. Following this cov'er plate 45 may be fastened in place by screw 46,

the abutments or stops 47 serving to lock the spring arms in fastening position; filling sleeve 20 may be now put in place, and dial plate 2411 snapped on.

With the described construction wherein the cover and handle are attached together to form a cover-handle assembly and the cover-handle assembly in turn is fastened directly to the soleplate by means of the front bracket and the rear spring arms, there is provided a structure wherein the cover, the handle and the soleplate are rmly united and one which enables the cover-handle assembly to be easily and quickly attached to the soleplate when the flatiron is being assembled; and likewise the cover-handle assembly can be quickly and easily removed from the soleplate by removing cover plate 45 and squeezing together the spring arms 3S.

The cover-handle assembly and its connection to the soleplate is entirely independent of the internal parts of the ilatiron such as the water reservoir and the filling tube so such internal parts may be made without regard to their having to perform any function having to do with holding the atiron assembled. As a result, they may be made of lighter weight material than would be the case otherwise.
