Application med February 15, 1911,

To all whom t may concern.'

Be itknown that I, LEON F. PARKHURST, residing at Binghamton, cbunty of Broome, State of New York, have .invented certain new and useful .Improvements in yElect-ric Sad-Irons of which the following isa full, clear, and exact description.

My invention relatesto electrically heated sad irons and is particularly concerned with improved means for connecting the leads ofthe circuit wlresfrom the source of energy.

with the'terminals ofthe heating units 1n the iron, whereby connection will be effected atla point 4removed from the heat of the' "bodyot the iron, `thus producing a more effective connection, while at the same time veniently arranged for ready connection of disturbing 4the assembly A further obj ect is to provide an improved ploint of their attachment to the iron whic the connections with the unit terminals of and will, at the same time, the end of the cable carrying the so position it will not interfere with the opleads that eration of the iron and will be preserved against breaking strain.

With these objects inview,

mentof parts, a preferred embodiment of which is illustrated drawings, in whichshowing my ina sectional view. on theline a Vterminal box embodying certain features of my invention; Fig. .3 is a sectional view Fig.A 2; Fig. 4 isa sectional view on the line 4;-4, Fig. 2; Fig. 5 is a deofQ the cable holder attaching the cable tothe iron, and Fig. 6 is a detail'view of the connectorsl employed in the terminalfbox.'

In the embodiment of my inventionherein'- selected for illustration, l indicates the base ofthe iron,2 the cover therefor, 3 the handle 'Ihe base of the iron is integral raised portion 5 within chambers in which the heat units 6-6 are suitably mounted and arranged, and the cover 2 forms a heat insulating air space 7 around Spec-ication o!

the portion 5 carrying the heat units. .The terminals 8-8 of the heating units are led out through an insulating sleeve 9 in ntlie cover plate and are secured to binding screws 1010 in a termina? boxcompr'ising a base 11 suitably secured to the handle bail 3 and havlng therein a porcelain block 12 'between 'which and the base of' the box is suitably interposeda layer 13 of insulating material, such as asbestos lumber. Heat insulating -washers 14 may be'interposed between the handle bail and the base of the box if desired. As indicated in Figs. 2 and 4, the porcelain block is notched, or slotted, at 15 to receivethe terminals the ,connecting members, or plates, 16-16 are mpunted, whichplates are heldin pos'ition by screws 17--17 and. receive the bind-l ing screws 10-10 respectively at .one end. At the opposite ing screws 18-18 to which the leads 19-19 of the cable 20 are attached. The porcelain block is also provided with a second notch 21 similar to and vpreferably located dia'- metrically opposite the notch 15 to receive the cable 20. The box is providedwitha suitable cover 22, preferablyflijned with in- `sulating material, such as a layeri23 of paper, and both the coverand the lining are slotted at- QA-25 to pass the'heating terminals and the cable. To attach the cover to the boX securely, and without distorting the al tubularpost 26 to receive a screw 27 which is threaded into the handle bail 3. and secures 'the cover `inplace.`

. By the. above described construction, it will be 'seen that the'terminals of the heating units are led outof` the body of the iron and are secured at a convenient point vfor connection with ythe leads of the energy circuit. Furthermore these connections are considerably removed from the heating effects of the body of the iron and are furthershielded by the terminal box.

In order to preserve the connection therewith of the circuit leads suitable attaching lbracket comprising a 28 having integral therewith an attaching arm 29 which ymay be convenientlysecured tothe handle bail by means of the boltV 4 which securesthe 8, which notch 1s mcllned from a point near the base of the -blockto the level of the raised seats in which the 'supply cable, the

end of these plates are bindthe terminal box and 'i to said iron independently of said terminal.

handle thereto, said arm being strengthened by reinforcing flanges 30-30. A second semi-cylindrical member 31 lis attached to the first by means of ears 32 formed to register with ears 33 on the member 28. The outer ends of the members 28 and 31' are enlarged somewhat as at 34, and such enlargement may have stamped therein a thread to receive a spirally arranged protecting Wire or armor 35 on the cable 20, Which preserves the latter against bending strains at the point of attachment. The tWo members 28 and 31, when 4clamped upon the cable, grip the same firmly and cause the threaded portion 34, at the same time, to take a firm hold upon'the Wire 35, hence this attaching member takes all of the pulling strain upon the cable and relieves the terminal box and the connection from said strain.

While I have herein described a particular-embodiment of my invention, it is to be understood that the same may be altered in detailsand in the relative arrangement of parts Within the scope of the appended claims.

'What I claim is:

l. In an electric sad iron,l the combination with an iron body having heating units therein, of a terminal connector located outside of said body having the terminals of said units secured thereto, of a supply cable having circuit terminals leading into said connector and means for securing said cable connections to preserve said terminal connections from pulling strains on said cable.
