l v In all the forms of the invention illustrated in the drawings the body of the iron is indicated in dotted line at A, and the hand piece at'B. The standards are preferably in 011e piece of metal bar folded in U-form with its upstanding ends constituting the two standards, and this bar is indicated throughout the drawings by the reference letter C. 1n all forms the hand piece, B, is of material having a low coefficient of thermal conduc- 40 tivity, such as wood, indurated liber, or wellknown refractory compositions having that thermal characteristic, and is tubular, that is, having a hollow cavity extending longitudinally from end to end, and in the forms 15 shown in Figures 1 to 7 it is recessed at the endsV around'the longitudinal cavity, or rabbeted, as seen at 10-l0, forming shoulders, 11-11. The marginal fianges, 12-12, at the P ends of the hand piece each have a notch, 13, 0 both said notches being at the same side of the hand piece and in alignment with each other for accommodating thev standards which extend up from the body of the iron and are formed at their up er ends for entering the Arabbet-shoulderorming recesses at the ends of the hand piece. The upturned ends ofthe bar, C, constituting the standards are designated by reference letters, C1, C2, CSs and C* in the respective forms illustrated, and in Figures 1 to 5 and 8 and 9 they have their upper ends fitted as described above in the recesses, 10-10, and at the center of their arcuate ends they have an aperture, 14, for a tie bolt, 20, which extendsthrough the longitudinal cavit may be in t e form shown in Figure 1 having a head, 21, abutting at one end against the outside of -a sup ort, C1, and exteriorly of the hand piece. This tie bolt threaded at the ot er end, beyond the other support C1 to receive a nut, 22. inthe form shown 1n Figure 4, the standard through` which the threaded end of the bolt extends ma have its aperture, 14:, threaded, and the tie olt may be screwed into it protruding at the outside to receive a jam nut, 23, the head of the bolt in that case being preferably slotted for screwing it into the standard Vas described. In the modified form shown in Figure 8 the tie bolt is without a head andis similarly threaded at both ends and dimensioned for protruding the threaded ends throughthe apertures, 14,0f the standards, C4, for receiving nuts, 23, outside the standards respectively. In either of the forms described the tie bolt is hollow from end' to end and constitutes an air duct through which a current of air is caused to pass by the back-and-orth movement of the iron in ironing.

.The rabbets forming'the recesses, 10-10, are deep enough to cause the encompassing flange, 12--12, to extend completely over the ends of the tie bolt and the securing nuts, so that the hand of the operator is guarded from accidental contact with the upper end edges of the standards or with the head or nut of the tie bolt, these metal parts bein liable to be hot enough to burn the hand i touched. Beside the ventilation provided by the hollow tie bolt it will be recognized that except in the forms shown in Figures 4 and 6 the tubular cavit of the hand piece provides a very substantially dimensioned insulation between the tie bolt and the inner surface of the hand piece; and to render this space not only effective for insulation by virtue of the air in it, but also effective for ventilation or air circulation through it, and as shown in Figure 1 it is rendered open at the ends by forming in the ends of ,the standards C1, which are seated in the end recesses, 10, of the hand piece arcuate apertures, 25-25, between the margins of said seated ends which obtain seating on the rabbet shoulders, 11-11, and the annular area around thel bolt aperture necessarily reserved for stopping the bolt head or nut and carrying the thread with which the bolt engages in the form shown in Figure 1. It will be observed that the apertures, 25, 25, are so located as to be in registration with the annular cavity around the bolt. 'Ihereare thus provided two through-and-through air circulation paths for carrying oil. the heat which may be radiated from the tie bolt or conducted to the hand piece by the limited contact of the standards, C1, C1, with the rabbet shoulders, 12-12.

A. third air channel is provided in the form shown in Figure 1 by interposing a spacing tube, 30, between the ends of the. standards, C1, C1, around the tie bolt, 20, said tube being exteriorly dimensioned enough less than the inner diameter of the hand piece, and interiorly dimensioned enough more than the outer diameter of the hollow bolt, to leave an annular air space aroundthe bolt and around Y the spacing tube, as is indicated at 41 and 42 respectively. The spacing tube is desirably dimensioned longitudinally to agree with the distance between the rabbet shoulders, 1111, at the opposite ends ofthe hand piece,

V'so that the tie bolt drawn tightly will clamp the ends of theV standards, C1, C1,

simultaneously against the said rabbet shoul.

ders, 11, and agamst the ends of the spacing tube, 30, the latter thus serving to relieve the i shoulders of the hand piece ofthe severe t stress which would be liable to deteriorate the non-metallic material of which the hand piece is necessarily formed, and" prevent the looseness which would be liable to result from that deterioration after limited use.

In order that the annular air space, 42, may serve not only for air insulation but also and especially as an additional path for air circu-A lation, the arcuate ends of the standards, C1, are formed with arcuate apertures, 27, 27, registering with the ends of said annular air space, 42.

In the form shown in Figure 4 the tubular spacer is dispensed with, and the hollow tie boltis made somewhat greater in 'diameter than the orm shown in Figure 1, substantially occupying the tubular cavity of the hand piece. The bar, C, whose upturned nan/,924

ends form the standards, C2, C2, in Figure 4, is stili' enough to dispense with any means oi" spacing the ends of the supports apart for rclieving the material of the hund piece of the clamping pressure due to tightening tht` nuts on the tie bolt; and the hand piece is dimen- .sioned between the rabbet shoulders, 11-11,

bolt and the spacing tube, utilizing the entire unobstructed longitudinal cavity of the hand piece for air circulation. In this form the stiffness of the standards C3 is relied upon to defeat their spreading apart so as to release the hand piece; and the engagement of the hand piece against vertical displacement for disengagement from the standards is afforded by making the notches, 13, less in width than the diameter of the recesses, l0, and forming the standards with their upper arcuate ends with diameter correspondingly greater than the width of the standard at the point at which they stand in the notches, 18.4 When made in this form, since the standards are too stiff to be sprung apart for entering the enlarged arcuate-headset the standards in the recessed ends of the hand piece, the standards are preferably formed of separate pieces and separately secured upon the body ofthe iron as seen in Figure 6. The upper or arcuate ends of the standards are provided with aper- For limiting as closely as possible the con- I duction of heat from the body of the iron through the standards to thehand piece, the area of contact of the bar, C, of which the standards are formed with the body of the iron, is reduced by flexing that bar upwardly out of contact with the body of the iron as seen at C3 between the points of its securement to the body of the iron by the bolts,-)15,

as seen in Figures 1' to 5 and 8 and 9. And

``for further limiting the conduction of the heat Wh1ch may be communicated even lby the limited contact with thc body of the iron,

the standards at their upright extent are apertured as indicated at 16, 16 and 17, reducing them to a somewhat skeleton form. Thesevapertures, besides reducing the cross section of the standards for limiting the conduction of heat by them to the hand piece,

serve the further purpose of permitting air currents to be directed through them under the hand plece and past the hand of the operastma-1 ator grasping the latter, with substantial cooling value both by diverting the normally ascending current of hot air from the body of the iron, and by facilitating direct radiation from the hand of the operator.

ln Figure 8 there is shown another modiiication consisting in forming the standards indicated in this 'form by the reference letter, Ct, with shoulders, 18 stopping against the margins of the notches, 13, in the flanges, `l2, of the hand piece, and locating the apertures for receiving the ends of the tie bolt at a distance from the shoulders corresponding approximately to the thickness of the Wall of the `hollow hand piece, so that the tie bolt extending through the hand piece is lodged,

against the inner wall of the latter attlie lower side, causing the hand piece to be positioned and fixed in position between said shoulders, 18, at the out-side and the tie bolt at the inside. In this form it is of minor iniportance thatthe tie bolt is hollow (though it is so shown in Figure 8), because of the longitudinal cavity of the hand piece being so slightly obstructed at its ends by the ends of the standards, that the air circulation through the hand piece is adequate for the desired cooling Without the additional cooling of the tie bolt which results from the hollow character of the latter..

lt Will be observed that the characteristic common to all the forms illustrated, resides in the provision of a hand piece having a tubular cavity therethrough, either in the hand piece proper, or by means ot a hollow bolt or tube, With the hand piece embraced endwise between a pair of spaced apart upright standards, Which `are provided with apertures located for registration or alignment 'with the ends'of the cavity to provide a continuous passageway from end to end of the hand piece for circulation of air therethrough.
