Fb, 24, 1948. E. H. CQQPER INSULATED FLEXIBLE SUPPORT FOR THERMALLY CONDITIONED TOOLS Filed Nov. 19, 19 16 Patented Feb. 24, 1948 UNITED STATES PATENT OFFICE INSULATED FLEXIBLE SURBQRT FOR THERMALLY CONDITIONED TOOLS 6 Claims.

The instant invention appertains to insulated, flexible supports, or mounts for thermally conditioned, or heated tools and instruments.

An important object of my invention is to provide a'heated.instrumentality mounted in an insulated, flexible and resilient coiled wire support having the provinces and functions of insulating thehandgrlpping portion thereof, simultaneously, providing an economical element of manufacture in quantity production, and at the same time, acting as a housing .for the electrical connections, or wires used .in conjunction with proper heating elements for furnishing the heated requirements of the tools constructed therewith.

A further object of my invention is to provide an insulated handle construction made of resilient, or spring means, having provision therein to receive an insulated head portion in which a tool, or instrument is secured,

A further object of my invention is to provide a toolholding portion made of resilient, or coilspring means secured to a hollow, conical handle made of plastic material for supporting therein the electrical connections andthe tool bit, or .instrument that requires thermal conditioning,

Afurther object of my invention is to provide a single coil spring element which will act as an insulator against, and aid in dissipating the radiant heat energy from a heated tool, the said coil being of such construction as to warrant economical manufacture thereof in quantity production.

Other features, and ancillary objects resident in my invention will become apparent from an examination of the accompanying drawings, bearing further elucidation in the ensuing description, wherein like symbols are used to desi nate like parts, and in which:

Fig. 1 is a front view of one form of my invention.

Fig. 2 is a cross-sectional view taken, substantially, on the lines 2--2 of Fig. 3.

Fig. 3 is a cross-sectional view taken, substantially, on the lines 3-3 of Fig. 1.

Fig. 4 is a slightly modified form of my invention, with certain portions thereof indicated in section, in order to better depict the structural features of this form.

Fig. 5 is a view similar to Fig, 4 showing another slightly modified form of my invention, with certain parts thereof broken away, in section, in order to more clearly show the structural relationship of the parts.

myinvention is generally designated 6, and consists of a coil ofwire functioning as a handle and having "a, tapered springlike handle portion Lands. series ofintermediate'body coils 8, which may be closely wound, or have spaces therebetween of uniform diamete for supporting the insulating, hand grippin element 57 made of cork, or other suitable insulating material.

The coils 8 extend beyond the edge of the tubular grip 1'! terminating in a reduced, closely wound coil section '9, adapted to receive therein the woodburning tool Hi; the said wood burning tool 10 being, secured firmly and rigidly in place by a cementitious composition l3, as indicated in Fig. 2. The wood burning tool it has a threaded portion 1! on its outer surface for a substantial length thereof in order to permit interchangeable attachment of various tools l2, such as soldering irons, or other tools requiring thermal conditioning for operation.

The tool 10 has a recessed portion I4 therein for housing a suitable heating element, which, in turn is connected to the wire l5 brought out through the terminal of the handle portion I, connected to an electrical plug to adapted for attachment to a wall outlet, or other source of electrical supply,

The tool illustrated in Fig 4 is similar to the one illustratedin Figs. 1 to 3, with the exception that the handle 201s made of a coil of wire which will also house the electrical wire it, and is provided with a closely wound coil portion 26 adapted to fit in frictional, and rigid, engagement with the reduced rear portion of an insulated bushing l8 made of porcelain, or other heatresistant material to which the tool It is secured.

The modification in Fig. 5 indicates a coil of wire 22 which is fitted inside of a hollow, conical shell 2|, having a recessed portion or bore 23 therein, and being made of plastic or other suitable material, the wire coils 22 terminating in a reduced portion 24, and having the tool l0 secured thereto by cementitious composition 25 similar to the method of securing the tool II] by virtue of the structure or composition l3.

It will be seen that with the type of tool illustrated in Figs. 1, 2 and 3, a very economical product of manufacture is provided, which is ideal for dissipating and disseminating the radiated heat currents, acting thus as a proper air-controlled insulator, making it convenient to hold in the hand, and simultaneously furnishing a housing for the electric wire it, at the same time furnishing flexure of the handle portion 1, as

Referring to the various views, Figs. 1, 2 and 3, indicated by the dotted lines, also providing flexflexibility at the point of operation of .the tool Ill. The said tool is preferably used for Wood burning, engraving, carving, and producing carving in wood, or plastics, or other similar materials responsive to heated tools. v

Although, I have herein indicated several modifications of the structural arrangement of parts, comprising my invention, it is to be understood that any variations therefrom falling within the skill of the average mechanic, is hereby reserved,

as falling within the purview of the appended claims.

Having thus described and disclosed my invention, what I claim as novel and desire to secure by Letters Patent, is:

1. In a thermally conditioned instrument, coilspring holding means having a reduced forward portion and an enlarged rearward portion, a tool bit secured to the said reduced forward portion, and a hollow handle secured to the said enlarged rearward portion, and insulated hand grip means removably confined about the outer portion of the said enlarged rearward portion.

2. In a thermally conditioned instrument, coil sprin handle means, heat resistant adapter means secured internally to one end of said handle means, a tool bit secured to the said adapter means, and insulated hand grip means secured removably about the outer portion of the end of the said coil spring to which the said adapter means is attached.

3. In a thermally conditioned instrument, coil spring retaining means comprising, a reduced forward portion, an enlarged intermediate portion, and a, rearward portion of substantially greater magnitude than the said forward portion, a thermally conditioned tool bit secured to the said reduced forward portion, and insulated hand grip means removably secured about the said intermediate portion.

4. In a thermally conditioned instrument, coil spring holding means having a reduced forward portion and an enlarged rearward portion, a tool bit secured to the said reduced forward portion, a hollow handle secured to the said enlarged rearward portion, and insulated hand grip means movably confined about the outer portion of the said enlarged rearward portion, electrical heating means connected to the said tool bit, electrical wire means connected to the said heating means and trained through the free end of the' said hollow handle, and plug means connected to the free end of the said electrical wire means. 5. In a thermally conditioned instrument, coil spring handle means, heat resistant adapter means secured internally to one end of said adapter means, a tool bit secured to the said adapter means, insulated hand grip means secured removably about the outer portion of the end of the said coil spring to which the said adapter means is attached, electrical heating means connected to the said tool bit, electrical wire means connected to the said heating means and trained through the free end of the said coil spring handle means, and plug means connected to the free end of the said electrical wire means.

6. In a thermally conditioned instrument, coil spring retaining means comprising, a reduced forward portion, an enlarged intermediate portion, and a rearward portion of substantially greater magnitude than the said forward portion, a thermally conditioned tool bit secured to the said reduced forward portion, insulated hand grip means removably secured about the said intermediate portion, electrical heating means connected to the said tool bit, electrical wire means connected to the said heating means and trained through the free end of the said rearward portion, and plug means connected to the free end of the said electrical wire means.
