ARCHIBALD S. CUBITT, OF PITTSFIELD, MASSACHUSETTS, ASSIGNOR TG GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.

ELECTRIC FLAT-IRON.

T o all whom it may doncer'n:

Be it known that I, ARCHIBALD S. Ctun'rr,

` a subject of -the King of Great Britain, re-

siding at Pittsfield, -county of Berkshire, State of Massachusetts, have; invented'certain new and useful Improvements in Elecftric Flat-Irons, of which the following is a Specification.A

This invention relates to electrically heated devices such as flat-irons and the like, and has for its object the provision of a device of this character which is .constructed in.

such a way as Vto provide a maximum etticiency with the greatest degree of simplicity.

In the construction of devices of this character it is common to clamp or othergvise secure a heating unit tothe body of the iron to heat the same.' l

One of the objects of my invention is to so arrange thc parts that the heating unit `will be firmly secured against displacement i in the 'course/of the following specification,

- sulating shields.

in which I have disclosed my 'invention embodied in concrete form for purposes of illustration. Q

In the accompanying drawing disclosing m invention7 Figure 1 represents a side view o my flat-iron partly in section; Fig. 2 is a plan view of the same with the cover removed, certain parts being broken away to show the structure; Fig. 3 is a section on the line 3 3 of Fig.- 2 looking in the direction of the arrows; Fig.' 4 showsa heating unit before it is flattened; and Fig.v 5 is a disassembled view of the flattened `unit and in- Referrin to the drawings, 1G .represents the body o the iron, 4 Thismay be of any desired form, and forpurposes'of illustration I have shown the common forin of iron having the heating units converging toward the toe. The body of this iron is provided with two grooves 11 which I have shown as V-sha-ped and converging toward the point of the iron. These grooves 'are for recelving the heating' unit l12, which 1s shaped to conform tothe shape of the groove.

heating unit is preferably flattened and then bent to -the Vshape as shown. @ne way in which this unit may be constructed, I have shown in the drawings. This consists in winding a resistance conductor 13 upon a tube 14 of the insulating material, such as pasted mica or the like. ,Y This tube is then flattened onto itself and bent to suitable form, as shown in Fig, 5. v- One of these units 12 is then inserted in leach of; the grooves 11 and is insulated from the metal by a strip ofinsulating material 15, which may also be mica. On the top of theunitis placed a similar strip of insulating materia-l 16.

The units .are held in the groovesnby means of clamping blocks 17wh1ch are likewise- V-shapedA as shown. These 'lolQck's arev secured together by the member 18 which connects them at about the middle of the iron. The cover 19, which is placed over the unit,

made between the unit and the body of the iron. The amount of machine work neces sary in an iron constructed in this'way is exceedingly small and the assembling is ac complished without difficulty as there are n.0 parts requiring accuracy of adjustment anddisplacement of the parts is impossible. A

single bolt suiiices to hold all the parts in place, thereby reducing both the cost of assembling and the. cost of material.

The units which I have described are very simple to 'make but it is obvious that my invent-ion is in no sense limited to this particular type of unit.. The two units in the present case are connected together at the point of the iron and the terminals are rought out to the terminal pins Q2.

While I have described my invention asv embodied in concrete structure for purposes is held in position by Aa bolt 2O which eX- of illustration, it should be understood that I do not limit myinvention thereto, since j various modifications thereof will suggest themselves to those skilled in the art withannexed claims.

. dat heating unit `portion@ having a V-shaped out departing from the spirit of my inveii` tion, the scope of which is set forth in the What i claim as new and desire to secure by Letters Patent of the United States, iS,--s

l. An electric fiat-iron comprisin a body portion having a groove therein, a at heat, ing unit bent to conform to the shape of the groove, and means for clamping the unit into the groove'- A 2. An electric fiat-iron comprising a body groove therein, a Hattened heating unit bent to conform to y the shape of lthe groove, and means for clamping the unit into the groove.v

3. An electric iatiron comprisin a body portion having a tapered groove tierein, a within said groove and a damping block conforming to the shape of the groove engaging the unit to press it into the groove. v

4.. An eiectric fiat-iron comprising a body portion having a V-shaped groove therein, a similarly shaped unit for said groove, and

.a fiattened heating a V-shaped block for clamping the unitinto the groove Y 5. An electric fiat-iron comprising a body portion having a pair of tapered grooves,

forming to the ape thereof, a clamping block for each unit, and a member engaging both of said blocks simultaneously to clamp the units in place.

6. An electric fiatiron comprising a body portion having 'a groove therein, a heating unit in said groove consisting of autube of insulating material having a resistance conductor mounted thereon and iattened onto itself, and a clamping block conforming to the shape of thegroove for ,pressing the unit into the groove.

In Witness whereof, have hereunto set -my hand this 26th day of October, 1910.I
