M. C. BERSTED FLATIRON CONSTRUCTION Filed July 8, 1925 31a/vanto@ MART/N G 13E/@TED Patented Mar. '18, 1930 UNITED ,STATES ATENT* GFI-ICE MARTIN C. BERSTED, 0F SAN DEGO, CALIFORNIA FLATIRON CONSTRUCTION Application mea .my s,

i@ rigidly secured to the body of the flat iron by means of a single screw; third, to provide a flat iron in which the handle supporting means is made of two straps interlocked with each other, the securing screw and the casing of the iron at their one ends, so that a simple and rigid connection is made, one which permits the iron to be readily assembled or disassembled; fourth, to provide a handle supporting strap means which may be punched from one piece into two pieces without waste of material; fifth, to provide novelly constructed handle supporting members or straps whereby the heat normally conducted from the body of the iron to the handle is reduced to a minimum; sixth, to provide a novelly constructed fiat iron, and seventh, to provide an iron of this class which is durable and which. will not readily deteriorate or get out of order.

`With these and other objects in View, as will appear hereinafter, my invention Lconsists of certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon, which form a part of this application, in which:

Figure l is a side elevational view of my electric flat iron, showing certain parts and portions thereof broken away and in section to facilitate the illustration of the means of securing the handle to the body of the flat 1 iron; Fig. 2 is a fragmentarysectional view thereof, taken through 2 2 of Fig. l; Fig.

3 is a fragmentary sectional elevational view thereof, taken through 3-3 of Fig. l, showing certain parts and portions in elevation 50 to facilitate the illustration, and Fig. 4 is 1925. serial No. 42,190.

a fragmentary front end View thereof, taken at4-4 of Fig. 1. p

Lilie characters of reference refer to similar parts and portions throughout the several views of the drawings.

rThe` casing l, for enclosing the upper plate and the operating and switch mechanism thereof, is mounted on the base plate 2 as in CIL the conventional construction. The upper p portion of the casing 1 at its median line is upwardly offset forming a longitudinal channel 1EL at its inner side, as'shown best` in Fig. 3. Near the front end and at the rear end of the upper wall forming this channel portion laL are provided transverse slots lb and' 1 l through which extend, respectively, the handle supporting members or straps 4 and 5. These straps 4 and 5 are of substantially the same width as the channel portion 1a andare positioned with their inner ends therein. Said straps are punched from one piece, being severed in such a manner as to provide a stepped or Z-shaped joint in a common plane as illustrated in Fig. 2. Intermediate the ends of the adjacently positioned longitudinally extending edges. 4CL and 5a at the abutting ends of the straps 4 and 5 are provided oppositely positioned, semicircular recesses 4b and 5b, forming a circularhole for the reception ofthe shank of the screw 6, which extends downwardly through ay hole in the casing and is secured at its lower end into the upper plate 3 ofthe iron, as shown in Figs. l and 3. In the iron shown in the drawings there is provided a bridge member 7 Afor supporting theswitch and other mechanism within the casing of the iron. This bridge member extends longitudinally withf in the casing and is positionedon the upper Y 4 and 5 extend upwardly from the bodyof the Y rfiat iron and are cupped at their upper ends,

as indicated by 4d and 5d, which provides only a small engaging edge of said straps against the ends of the handle 8 positioned therebetween and secured thereto by means of a long screw 9 and nut 9a extending aX- ially through the handle. The straps 4 and 5 are longitudinally perforated near their upper ends secured to the handle 8, as shown best in Fig. 4, thus cutting down the crosssectional area materially andl reducing the conduction of heat to the handle to a minimum, the construction of the upper ends of said straps also reducing vthe conduction of heat from said straps to theV handle to a minimum.

. Though I have shown and described a particular construction, combination andV arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims. Y

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: i

1. In a flat iron structure, including a hot plate, a casing provided at its upper portion with an inverted, upwardly extending channelportion, ahandle, a pair of handtle supporting straps offsubstantially. the width of said. channel, thel one end portions of said straps being connected to opposite ends of said handle, the other end portions of said straps extending into said casing and length- Vwise within said channel with their ends in abutment therein, the lower surface of said end portions lying substantially flush with the inner surface of said casing and in equal spaced relation with the upper surface of said hot plate, and unitary means for securing said members in and to 'said casing.

2. In a flat iron structure, a casing provided with a pair of openings in its upper portion, an upper plate positioned within said casing, a bridge member between said upper plate and said casing, a handle, a pair of handle'supporting members each having one end attached to said handle andthe other end extending through one of said openings and abutting against each other at said ends.

between said bridge member and said casing, said abutting ends forming a steppedjoint in a common plane, and a screw'extending through said casing and said bridge member and through recesses at the adjacent edges of the abutting ends of said members clamping the inner ends of said members between the casing and said bridge member.

3. In a flat iron'structure, a casing provided at the inner side of its upper portion with a medially extending inverted channel portion'having transverse slotsnear its forward and rear ends, a handle, a pair of handle supporting straps each having one end attached to said handle and the other end eX- V`tending through one of said slots and positioned with said ends in said channel ortion, the inner ends of said straps being o set laterally and abutted at said offset ends with each other with the sides forming said oifset ends being positioned adjacent each other, an upper plate positioned'within said casing, a bridge member positioned within said casing on said upper plate, and a single screw extending-through said casing and through recesses in the adjacent sides of the abutting ends ofsaid'straps, positively locking the inner ends of said straps relatively to each other in said channel portion and securing the inner ends thereof against the upper'side of said bridge member and said bridge member against said upper plate.

t. In a Hat iron structure, a casing provided at the inner side of its upper portion with a medially extending inverted channel por-V tion having transverse slotsnear its forward and rear ends, a handle and a pair of handle supporting straps each having one end attached to said handle and the other end eX'- tending through one of said slots and posi- Y said outer ends having relatively large, cup

shaped, inwardly facing depressions therein and'forming relatively narrow lines of contact with. said handle member. Y. Y

In testimony whereof, I have hereunto set my hand at San Diego, California, this 29th n day of June, 1925. f v MARTIN 'BERSTED iis
