W. S. HADAWAY,`.|R. CURLING IRON HEATER. APPLICATION FILED ocr. 1o. 1913.
Patented July 13, 1915.
Imm-mm WILLIAM. s. HADAWAY, Jn., or NEW ROCHELLE, NEW YORK.
". 5 Aorientare-mori HEATER.
To c lljauhot it may concern." v .Be 1t known thatI, WILLIAM S. HADAwAY, Jr., a citizen yof the .United States, residing at New Rochelle, in the'. county of Westchester and State of New `York, have invented new and useful Improvements in Curling-Iron Heaters, of which the following isa full, clear, concise, and:eXact de` scrip'tion, reference being*y had to the ac-v companyingdrawing, forming a part ofthisspecification'.
AMy vention relates to curling-iron heaters of the wall type. .I Devices of thischaracter, as constructed heretofore, have required'the turning on of the heating curlrent as an-act separate and distinct from the insertion of lthe curling-iron, andas a preliminary thereto; Infcertain cases, lthe entrance of the heating chamber has beenv completely `'closed by a slidingv gate which l required to'` be slid to 'one side to. permit thev 'curling-iron to be inserted.` fT-he complete v operatiomtherefore, 'involved the use ofv both hands. With one hand thel gate was slid to .open position, 'an d' .with the other hand.` the curling-iron was inserted.`
Onel of the objects of myl invention isvto provide/an improved construction whereby l .only one hand is required to insert the curling-:iron in vthe heating chamber, .the saidy insertion. being accompanied necessarily and yautomatically by'.theclosing'oftlie'heating` circuit, the .latter being likewise openedfby 'the withdrawal of said curlingfiron.-

The structure, in-its preferred'form, comi prises, generally speaking, an outlet boX l set into awalhbeing embedded usually Kin the plaster, and a supporting' plate 2, which .carries all` the remaining lparts ofv the def' vice and whichis secured to the frontof the outlet box and covers the open en d thereof. The outletbox, which is madepreferably of sheet metal, need not necessarily constitute ,part of theeoluipment as manufactured,but
may be installed 'at the time `the roomis s s plastered, for example. The curling-iron ,heater proper mayl thereafter be installed simply'by'securing it in-positio'n. `For this purpose, the frontof the outlet box is pref-v erably flanged inwardly as at 3, said flanges each having a screw-threadedhole itherein, las shown. The supporting plate 2, which is made preferably of castiron, is heldto said .flanges by. screws 5 passing through `e'lon- #gated openings 6 tliereimthe latter permitting a slight adjustment o f said plate, if necessary. The outlet box may be provided further with a suitable opening or openings -7 to permit the introduction of conductors from the usual conduit located in the wall.
A heating tube s is rated within a Suitable opening in the supportingplate 2, said heat ingtube having a suitable resistance wire 9 wound about the-same and insulated there-4 from by insulationy 10 of any approved kind.
'Said heating tube is open at both ends and is secured at its forward end tothe outer face of the supporting plate by screws l1, 12. The screws 12 also securely 'hold in place one end ofa resilient member 13, which is prefsA erably a strip `of metal, said strip `being arranged somewhat diagonally. with respect to the main aXis'of the'tube, and extending through .the rear end thereof. A suitable bridging member 14 is carried by. the rear end of said strip, which latter is preferably bent up above the heatingtube, whereby vsaid bridging membermayclose the circuit between a pair of resilient Contact members l 15. Said bridging member is preferably in- Asulated from said resilient strip, being secured thereto by metal pins or rivets' 16, but s aced therefrom by suitable llayers of mica 1%, arranged on bothsides thereof, as shown.
, The Contact members 15 are' each secured in any suitablevmanner to a 'metal bracket-18,- thev latter :being secured .to the wal119 of a,

. upward movement ofthe latter.
yshallow rece/ss in thev supporting plate 2. l
|lhe rear ends of said bracket 18 constitute stops for -the resilient contacts 15, said con. tacts being lifted somewhat by the bridging member-14 when the circuit is closed bythe The insertion of the curling-iron forces the resilient strip V13 to one side, thereby moving the bridging member 141to circuit-closing posi-` tion, the various parts being moved about as indicated in dotted lines in Fig. 4.
The brackets 18v are secured in place 'by suitable screws 20,21, as shown. An additional screw 22 passes through' the wall 19, previously'mentioned, the screws 20 and 2 2 i constituting'binding posts or terminal connectors for the conductors which `enter the outlet box and which are brought forward.
.through an opening 23 in said wall 19. One
of saidterminal screws is electrically conand the other terminal screw is electrically connected to the resilient contacts 15,` thel vother of said contactsbeing connected. to the remaining. end of said resistance wire, whereby the .bridging of said contacts 15 by the bridging member 14 closes the heating circuit. l
The supporting plate2 isl provided withA a marginal flange 24 having a pair-of lugs v25 provided 'with' screw-threaded openingsl 26 therein to receive the screws 27 which -.hold the cover -plate 28 inposition -against the front of lsaid supporting plate. The cover plate is of ornamental appearance and is'provided .with a suitable vbeveled edge, as
shown in Figs. 1 and 4.- It has also an opening 29 therethrough in alinement with thel heating tube. 4Thefsupportlng plate 2 over-'- lies the. wall somewhat, as shown in Fig.' 4,- and being of substantial thickness, the
cover plate is notflush with the face of said wall. However, it only projects a comparatively short distance therefrom s0 that the appearance of" the device as a whole is very unobtrusive. V The thickness ,of said plate is due to saidl flange 24, the provision of which permits the cover plate to be spaced` 'some little distance from'the supporting plate, whereby a` suitable airspace is pro-4 vided. Openings 30v are preferably pro'- vided in said ange, both at the top and bottom 'thereof,' whereof acirculation of 'air through said vclearance space is promoted.v

embodiment in various other forms. cordingly, Ido not desireto limit myselfto tuatedb the heating clrcuit.
curling-iron, which insertion results in clos- Furthermore, the withdrawal of the curling-iron opens the heating-circuit, whereby waste of current is prevented. Only one hand is required for eitheroperation. After the curling-iron has Y been thrustlnto the heating chamber, it ,is
frictionally held in position by the pressure of the resilient strip 13 thereon. A further .advantage ofthe arrangement described is that no elaborate manipulation of any of the parts of the device 1s required, such as might, render dlfcult the use of the device by per-I sons not familiar therewith,A Also the absence of projecting lswitch-actuating knobs or levers not only greatly improves the appearance of the device, but renders it less liable to be derangedby careless users.4
It will be understood, of course, that the above described embodiment of the invention represents only the' preferred form thereof, s aid invention being susceptibleAof the structural details andrelative' arrangementofparts described and illustrated,but desire to Acover in the appended claims whatever suitable equivalent meansmaybe devised whichl fall within the scope .of said claims.
1 What I claim as new and desire to secure by Letters Patent ofthe United States is: 1. In a curling-iron heater, a heating tube, a resilient strip of metal secured at the `front end thereof and extending inwardly diago nally across the here of said tube, whereby the insertion of the curling-iron forces said strip to a position more nearly parallel with said bore, and circuit closing `contactsacv the movement. of said strip to close 2. A- curling-iron heater comprising a" sup- 4 .porting plate havingan opening therein, a
heating tube supported at its forward end in saidop'ening, a resilient metal strip extending through said'tube somewhat diagonally and secured/at its forward lend ad? .jacent to said opening-acontact bridging member at the rear end of-said strip, anda '.1
pair of 'contacts' carried by said plate-'and adapted to be bridged by said member.
3. In-l combination, an outlet box havinl an openend, a supporting plate-closing sai end, aheating tube. open at both ends and projecting rearwardly/ from an opening in said plate into said outlet box, accver plate Secured te the. forwarded@ of sind support-.'- ing plate and spaced therefrom, sald cover.`
plato having an opening therein above said` heating tubeto lfacilitate circulation of air through said outlet* box and having marginal openings where lit joins said cover plate to provide ventilation therefor.
4. In a device of the class described, a
supporting plate having a shallow recessed" within said opening, and a cover plate iitting over said iange.
5. A curling iron heater having a heating chamber, a resilient strip of metal mounted adjacent one end of the chamber and extendv(.mr'ec'c-on in Letters Patent No, 1,146,758.
ing diagonally into said chamber so that it is adapted to be moved by the insertion of a curling iron, said strip having an electrical contact mounted thereon coperating with other electrical contacts on the outside of said chamber to complete a circuit upon the insertion of a curling iron.
