Application March 18, -1937, Serial No. 131,571

9 Claims. (Cl. 219-25) 5 and home, are provided with a metal base, a metal cover and an insulating handle, the heating element being enclosed in the metal base so as not to be visible.

As a result, the iron will often be heating and ii) the current will be turned on without its being brought to the notice of the user or possessor. It is often desirable to determine when the iron has been left burning or whether it is turned off and it is among the objects of the present in- 15 vention to provide an inexpensive, durable and readily operable electric iron construction of this character in which it will be possible for the housewife or domestic servant to determine when the iron is operating and/or when the current.

has been turned off.

Otherobjects will be obvious or will appear during the course of the following specification.

.In accomplishing these objects, it has been found most desirable to provide a glass window 25 or glass cover for the iron construction which may be a unitary part of the iron construction, and, at the same time, will enable ready observation of the heating element thereof.

In one type of construction, the iron base is 00 provided with a peripheral ridge and with a centrally positioned tapped boss, the back of the iron being so arranged that a glass cover element may he slid into position and prevented from sliding off the iron base by a single bolt.

35 This bolt may also serve as a means of attachment for a handle and an electrical plug member, which handle and plug member may also be detachably connected to the rear of the metallic base.

40 The above and other objects will appear more clearlygfrom the following description when taken in connection with the accompanying drawings showing preferred embodiments of the inventive idea.

In the drawings:

Figure 1 is a side view of one form of electric iron construction.

Figure 2 is a top view upon the line 2-2 of 50 Figure 1.

Figure 3 is a rear view upon the line 3-3 of Figure l.

Figure 7 is a cross sectional view upon the line 5 1+1 of Figure 4.

Figure 8 illustrates a slightly different embodiment in side sectional view similar to Figure 4.

Figure 9 is a top view partly in section on the line 9-9 of Figure 8. 10

Figure 10 is a rear view upon the line Ill-l0 of Figure 9 with the handle broken away.

Figure 11 is a bottom view upon the line l'l-i i of Figure 8 with the glass cover.

Referring to Figures 1 to 7, the electric iron 15 includes the base A, a transparent cover B, and

. handle C and electrical connection D.

The base includes a relatively flat metal plate l0, which converges to a point II, at its forward end, and the sides of which are inwardly bevelled as indicated at i3. is

The sides have an upstanding lip M which is riot present in the rear l5, within which lip I5.

is received the glass cover member B.

The glass cover member B is provided with a peripheral recess I5, which receives said lip it,

the outer face ii of said cover being flush with the bevel face l3 and the base A.

The glass top is recessed as idicated at I! in Figures 4 to '7 and is provided with a peripheral portion [8, which contacts the mica plate 69, and presses against the interior face 26 of the base A.

In the lower face of the portion I8, is the peripheral groove 20, best shown in Figure 6 which extends entirely around .the' cover B and is pro- 5 vided with the inlet and outlet portions H (see Figure 6) Within the groove 20 is positioned the electric coil 22, which at the rear end of the iron is connected to the electrical conduits 23 (see Figure 4). .40 These conduits '23 are connected at 24 to the prongs 25 designed to receive an electrical connecting plug .indicated'in dotted lines at 26 in Figure 4.

The prongs are enclosed by the casing 21 which receives the sides of the plug 26 and said cas ng 21 with the prongs 25 are mounted upon a spring steel base 28 which has. a lower portion 29; the base 28 and the lower portion 29 enclosing the lead in wires 23.

The spring base 2829 serves as a support leg to enable the iron to be placed in upright position.

v The lower plate 29 is provided with an enlargement 30 opposite the connections 24 to the plugs 25 and it has a flange 3| fitted into the recess in the rear of the base A, and screwed into position by the screws 32.

The upper plate 28 is turned upwardly, as indicated at 33 over the back portion 34 of the glass top B, and at its forward end 35 it is received in the recess 36 on the top of the cover element B. i

Below the front end 35 of the plate 33 is the gasket 31 and above the plate is the inturned flange 38 of the back element 39 of the wooden handle piece 40.

The bolt 4| extends through the flange 38, the element 35 and the gasket 31 and through the opening 42 molded in the glass cover element B, the lower end of the bolt 4| is screwed into a tapped socket in the boss 44 projecting upwardly from the interior floor 20 of the base A.

In assembling the recess I! may be conveniently placed over the boss 44, as shown in Figure 5, and then the cover B may be slid into position until the lip I4 of the base A fits into the reces 15 of the cover B.

Then the flange 3| of the connecter D may" be attached by the screws 32. Finally, the cover B and the plates 35 and handle C may be bolted in position by the bolt 42.

The gasket 31 will take up tightening of the bolt-4i without straining the glass B.

The mica gasket or insulating layer [9 will prevent direct contact between the heating coil 22 and the base A, while at the same time permitting the heater coil 22 to be visible from the top of the cover B.

It is obvious that the glass top may be assembled with the base A in other manners than shown, and if desired, the base B may be made of Pyrex glass or some other heatr sistant glass.

It is also possible to make the cover B partly of glass, instead of entirely of glass as shown, so long as the heating coil 22 is visible from the top of the device. For example, the base could be provided with ametallic extension extending over the top and rear of the base A and carrying the handle C and the connections D, which metallic extension upon being bolted in position bolt 4| would hold a glass periphery .a position exposing the heating coil 22.

In the embodiment of Figures 8 to 11, similarly functioning parts to those shown in Figures 1 to '7 are indicated by the same numerals primed.

In Figure 8, it will be noted that the lower edge l5 of the glass cover is not recessed and that the adjacent lip ll of the bottom A has a. substantially sharper inturned angle, as indicated at 60 in Figure 10.

The adjacent edge SI of the glass cover B is turned slightly outwardly at an angle varying between 10 and 30 degrees with a preferred angle of 20 degrees.

The foot portion 18' of the glass cover B- is provided with a series ofrecesses 62 which extend inwardly from the channel 20' to the hollow- IT in the interior of the iron.

These channels 62 permit circulation of hot air from the heating coil 22' into the hollow space 11 where such heat will efiectively elevate a temperature of the bottom l3 of the iron. 7

In the construction of Figures 8 to 11, the transparent top B is not held in position by the bolt 4|, but solely by the connection between the lip Wand the upwardly bevelled edge 15.

The boss 43' which receives the bolt 4! is inclined upwardly and rearwardly and a spacer sleeve 63 is provided upon which the inturned portion 38 is clamped.

The flange portion 38 01 the handle extension 33 flts into the recess 42 in the top of the cover B. The portion 39' of the handle is provided with a recess 64, which receives the parallel hooks 65 which hooks extend away from the enclosure 21, into which a plug, not shown, may be inserted. a

The enclosure 29 is mounted directly upon the top of the glass cover B and the lead-in wires 23' extend downwardly through the recess 66 in the glass top, said recess 66 together with the recess 42 constituting a T-shaped slot, as shown in Figure 11.

From the enclosure 21 extends the bent metal tially vertical when not in use.

The embodiment of Figures 8 to 11 shows a I light weight glass cover B firmly held in position by the lip II and shows the handle C devoid of all connection in respect to the glass cover B.

Moreover, the construction of the glass top B with the heat conveying channels 62 permits an intensification of the heat effect in the holder space H which is communicated to the base [3.

It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
