FLUSH CURLINGJRON HEATER.

Specification of Letters Patent.l Patented D433l 20, 1310.

Applcationled une 3, 1510./ Serial N o. 564,747.

To all whom it may concern: Be it known that We, JAMES I. AYER and Hormon B. GALE, citizens of the United7 States, and residents, respectively, of Cambridge and Natick, in the county of Middlesex and State of Massachusetts, have invent-y @ur invention is an improvement in curling iron heaters, whereby greater elliciency,

neatness of appearance, convenience and durability are attained. A further object of the invention is to provide an instrument especially adapted, for instance, to hotel use, the instrument being constructed as a wall pocket to beset into the wall flush with the outersurtace thereof so that it becomes practically irnpossible for it to be tampered with or materially injured by the carelessness or curiosity of the hotel guests. y

The constructional details and further ad- Vantages of our invention will be pointed out more at length in the course of the description taken with reference to the accompanying drawings, in which we ,haveillus trated a preferred embodiment ofthe invention.

-lln the drawings, Figure 1 is a central ver tical sectional view ot the complete instrument shown in place in awall; Fig. 2 is a view thereof in front elevation; Fig. 3 is a horizontal cross sectional viewon the lined..v 3-3 Fig. 1 Fig. 4 shows the instrument in front elevation with the face plate removed; Fig. 5 is a vertical cross sectional view on the line .55 Fig. 1; and Fig. 6 is a View of a fragmentary portion of Fig. #lf showing the gate or slide closure in a different position.

In a wall box l closed. on all sides excepting its front and provided with an opening 2 for the circuit wires 3 and preferably with a similar opening 4 at the opposite side in case the wires should have to enter from the bottom, mounted a U-shaped frame 5 secured at its laterally bent or outturned ends by screws G to a supportingand closingplate 7 y which closes the open front end of the box 1.

The frame 5, closing' plate 7 apd parts supported thereby are secured ilnmovably in the box 1 by screws 8, one adjacent the upper right-hand corner and the other adjacent the lower lefthand corner, passingthrough angle irons or lugs 9 projecting therefor from the adjacent ends of the box 1. A heating tube 10 is supported at its flared outer end on a rearwardly projecting flange or rim 11 of the plate 7 and at its rear end on a pref` erably spring plate 12 riveted at 13- to the rear end of the frame?) so that said heating tube is directly beneath and in the plane of the said frame 5, as best shown in Fig, 5. This heating tube is surrounded by a` coil of Vresistance heating-wire 14 embedded in vitvtube 10 as clearly shown'in Fig. 1.

reous enamel 15, said wire receiving current through` conductors 16, 17, controlled by a switch mounted on a base 18 of slate or other insulation bolted at 19 `to the frame 3.

The switch 1' comprises "a bent-over leaf spring 20 secured at 21 to the base and provided with a knife contact 22 tov cooper-ate with contact springs 23 secured by binding posts Q4, 25 to the base. Binding postst areV provided for the feed wires 3. The

switch spring 20 alsopreferably carries 'an upwardly and inwardly bent deflecting spring or guard 9.7 which extends into the The supporting and closing plate 7 is provided on its front side with a4 depression or way 28 in which is mounted a sliding gate 29 for normally closing an opening 30 in alinernent with tle tube 10. Said gate 29 may be movi ably supported by any suitable means, being preferably supported on a projecting end 3() of the switch spring. The plate 7 is also provided with a lateral opening 32 and the 'gate 29 is provided with a neck-shaped opening 33 so that when in upright operative position as shown in Fig. 4, the spring projection 31 occupies the narrow neck portion of the slot, but when the gate is moved laterally so as to bri-ng the spring 3l into the enlarged portion of the opening 32%. said gate can be turned'to the position shown in Fig. (l, thercbjv entirely exposing the opening` 32 so thatl the ojwi'ator can readily get at the binding post 26 for fastening or removingtherefrom the wires 3. Normally the apparatus thus far described is covered rby a Vface plate 84 secured in place by screws 35. said tace plate being prov'idedlwith a neck-shaped opening 36 whose enlarged upper end alines with the opening 30 and the tube l() for receiving the curling iron; An

external knob or finger-hold 37 is provided for operating the gate 29, said knob being mounted prferablycpnvenient to said gate and for convenience not directly on the gate but on some adjacent moving part, herein shown as the end of the spring 31, and arto open the apparatus for the reception of the curling iron. This same downward movement of the knob closes the switch and thereby turns on the current. Also the same movement depresses the detlecting spring or guard 7 so that when the curling iron enters it engages said guard and thereby holds the switch closed while the iron. is being heated. At all'times the apparatus is entirely out of reach, being wholly concealed in the wall fw of the room or place where the heater-,is provided. The construct-ion is light, strong and simple. If any part breaks t-he face plate is removedand then the frame and all its connected parts can be readily taken out from the pocket without in any Way. disfiguring the Wall or causing inconvenience.

Many other advantages will be obvious'to those skilled in the art.
