To all 'whom t may concern.'
Be it known that I, ROBERT B. BEST, a citizen of the United States, residing at Great Neck, Long Island, in the county of Nassau and State of New York, have in vented a new and useful Asbestos Handle, of which the following is a specification.
This invention relates to improvements in asbestos handles whereby a handle is provided which is adapted to resist the destructive action of heat and to remain in a cool condition.
With the foregoing and other objects in view which will appear as the description proceeds, the invention residesin the combination and arrangement of parts and in the detailsof construction hereinafter described and claimed, it being understood thatchanges in the precise embodiment of the invention herein disclosed, can be made within the scope of what lis claimed without-de# parting from the spirit ofthe invention.
In the drawings accompanying this specification and forming a part thereof, the pref erable form of my invention is illustrated, in which v Figure 1` is a view inelevation illustrating my improved form of asbestos handle. Fig. 2 isa longitudinal sectional view thereof.
Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 is nthe handle core which is hollow cylindrical in form and provided with the enlarged head 2 internally threaded as at v3 so that the handle may be detachably secured to solderu ing irons, pokers, branding irons or other similar tools which of necessity are placed in fires and require a handle formed of some heat resisting. material. The enlarged internally threaded end S'is provided with thev outstanding annular flange 4 illustrated as being integral therewith and which provides a suitable stop or shoulder against which theV compressed asbestos body portion 5 contacts.
with. The opposite end of the hollow core l 1s externally threaded as at 6 and engaging the same is the securing nut 7. The body portion 5 preferably formed .of compressed asbestos is provided with a suitable axial opemng 8 extending therethrough and which is adapted to it over and conform to the outer peripheral surface of the core 1. The securing nut'7 is embedded in the body p0rtion so asl to be flush therewith and to ehminate all sharp projections.
In order to insure that the entire handle will be maintained in as cool a condition as possible, suitable .apertures 9 are provided in the .enlarged end of the core beyond the flange 4 and these apertures in connection with the open end 10 of the core rovide for the circulation of air through t e core to thereby maintanthe same and the entirev handle in a cool condition.
It has been found in practice that asbestos possesses a high coefficient-of thermal resist- I ance and therefore heatV from the core will not pass through the body portion'y 5 to any great extent. Furthermore inasmuch as a constant circulation'of air has been. provided for, the core will not be heated to any excessive temperature under all ordinary conditions. Furthermore asbestos has been found to successfully withstand the direct Ycontact with flames so that accidents which would destroy ordinary handles would have little effect upon the-one hereinl described. Furthermore due to the high coetiicient of thermal resistance, which is the same as saying that the material 'has a low coefficient of thermal conductivity, the device provides that, though the asbestos itself be at a high temperature, the effect upon the hand of the operator will not be largely influenced thereby, as it would if the Substance forming the body portion of the handle was of some material having a high coeiicient ofconductivity. Furthermore, mention is made of the 'factthat the body portion of compressed asbestos is removably secured'to the hollow core and may `bereplaced after the usefulV ,life'thereof has expired.
What I claim is In a device of the class described the combination of a hollow core, means located at one endl thereof whereby the same maybe affixed to an article to act as a handle therefor, an outstanding flange carried by said core adjacent thesaid end, a fire resisting body portion having a low coeliicient of thermal conductivity detachably secured to said core, having' surface Contact therewith, abutting said flange, and of a relatively smaller diameter than the said ange at its point of contact therewith, means engaging the opposite external end of said core, contacting with the saidbody portion and adapted to hold the same rigidly in place, said core provided with a plurality of air ducts extending through the side wall thereof intermediate its end and said flange, the opposite end of BoBEBT B. BEST.
