H'nArI'Ne D'E'vrcn non itam TREriiintS-rg application tied setefiuier Ourinvention relates to devices for curl- `ing or otherwise forming hair Einto ydesired referring to "the'drawings which torm apart bfthisspeeification..V i l Fig. l is a longitudinal yvieu/,partly in se.ction, of a heatingel'ement,embodying our'invention.

Fig. 2 is an end view taken on line 2--2 ot' Figure 1. l

Fig. 3 isa cross-sectional view -takenon line 3-3 of Figure l.

Fig. l is an illustrational sectional view showing a metal ring imbeddedV andmoulded in a covering of suitable insulating material and the construction of the contacting terminals `for the wires carrying the heating current.

"Fig 5 is a plan view of a `modied construction, ehowing a metal ring with bushings ot insulating material fined therein tov support the wire terminals. Y

Fig. 6 is a vert'cal sectional view through the ring showninv Figure 5, taken online 6-6 thereof, and a sectional view of the cap portion ot the device, with'the screws to hold it to the ring.l

Fig. 7 is a cross-sectional View of an insulated wire usedas a'heater in the device.

Fig. 8 is a view, partly in section, of one en'd of the insulation, and the wire therein, and illustrating how the wire is held in contact with a flattened band-portion used in making the terminalicontact portions. A indicates a thin metal `tube of light material such as aluminium and provided with `a hany dle A of cork, felt, yor 4other suitable heatinsulating material.

Mounted-on the tube A in tight fittingrelation thereto, is a metal :ring B whichisprovided with two notches B in its outer lpe-f riphery loca-ted diametrioally opposite to each other, and ftw'o lnot-ches B? in lits 'inner' periphery, also. located diainetrically -oppo. site to each other, the notches BV and B2 at each sideiol' the` ring being located adjacent to eachother, asShW'n. The ring B is imbedded in a ring of insulating material C e5, 1925. serial no. 63.496.

lwhich also fills the notches 5B and B2. :Holes lD-iD-D-D respectively are formed `in the insulation ofthe ring where it is lo- 'catedinthe'notches B and B2, toreceive the -iiat band terminals E E respectively, 'which are connected directly with the ends of the round wire heating` element F located inthe asbestosl covering F. i f

The flat band 'termi-nal `portion E is held in contact with the round wire-F bya 4circular band 'G at "each end,v which lband is clamped tightly around the 'insulationF and over the'contactiiigends kof the terminal band E 'and wire F, as clearly illurated in Figure 8. lThe flatr band Lterminals E lare Vthen passed through their 'respective holes D in one 'direction and I'arebent `overland their free 'ends passed lintothe holes 'D respectively adjacent thereto in ktheopposite` direction to form a hook which not only holds the ends `firmly in position, but permits `the lheating elementto be drawn firmly vin contact with the centre tube A, `as will be readilyunder"y stood. v

`'lhe terminal conductor stripsandfthe con# duc'tors have a lower yelectrical "resistance than that oi" theheating element sotliat `the heating element only, acts to generate heatj.

An outer tube H is provided, onewend .of which is reduced in diameter'to'ht in slidingengagement with the inner tube A, and its oppositeend is madeto'iit over the outer periphery of the insulating Tring C 'and is held in position by ascrew I which passes through the tube H, and insulating ring 'C and screws into the metal ring B, which in turn is secured tothe centre 'tube A, thus making a complete unitary lheating. element.

A ring-shaped cap `portion J is made to M for thev conductors, L-L respectively,V which holes are-located directlytopposite to and spaced Itrom Ieach *other Ato correspond.

with the 1holes D4-1).` The hole M is large enough to `receive the wirek and .covering jot the 'conductor "L, Y whereas the hole i-Mfis largelenough `to receive 'the bare :wire only, which is bent into 'f a hook` 'formi as' illustrated, and is held in irm contact with therelativelyl Wide bandterminal E by the`soretvs 'l-K, as. willbe 'readily understood.

In Figures 5 and 6 we have illustrated a,

inodilied construction in which the metal ring B is not imbedded in insulating material but bushings N-N respectively are inserted in holes in the ring, and the tops of the bushings are flanged to provide a fiat surface on which the Hat band terminals E-E respectively may rest, the holes through the bushings serving the same tunetion as theholes DD serve in the construction shown in Figures 3 and 4.

By the construction above described lirm and durable device is provided that will give plenty of area of contacting surface between Ythe round wire heating element and Hat band terminal and. with the round wire conductors L.

The construction also permits ot easy assembling of the parts, and removes all danger `of burning out at the points of contact of the terminals.

Having thus described our invention, we claim as new:

l. An electrical heating device comprising a tube, a ring mounted on said tube, insulating material carried by said ring` Vand having holes therethrough, a terminal wire extending through one oi said holes in one direction and into one of said holes adjacent thereto in the opposite direction to form a hook-shaped terminal.

2. An electrical heating device comprising a tube, a ringmounted on said tube, insulating material carried by said ring and having holes therethrough, a terminal wire having a flattened'surfaceextending through one of said holes in one direction and vinto one of said holes adjacent thereto in the opposite direction to form a hook-shaped terminal.

3. An electrical heating device comprising a tube, a ring mounted on said tube, insulating material carried by said ring and having holes therethrough, a terminal wire having a flattened sur'i'ace extending through one of said holes in one direction and into one of said holes adjacent thereto in the opposite direction to form a hook-shaped terminal, a conductor leading to said terminal and means for holding said conductor in overlying contact relation with said flattened surface. i
