ELECTRICALLY-HEATED TOOL.
Specification of Letters Patent.
Patented May 14, 1912.
Application filed July 13, 1908. Serial No. 443,260.
To all whom, it may com-cm departing from the spirit of my invention.
Be it known that l. Leos l. liniiinits'r. i
and useful Improvements in .l llectricaltv-t Heated Tools, of which the following is a SPOClfiCtll-ltlll.
This invention relates to electric heating devices, and has for its object the provision of a device of this character in which the energy of an electric circuit is converted into heat in a thoroughly etiicient manner,
7 and which at the same time is exceedingly simple to construct and is provided with isily renewable parts.
My invention relates more specifically to electrically-hcated tools, such as shoe ironing tools and the like.
One of the ol'tjects of my invention is to provide a tool of this character in which the electric heating unit" is of the selt'-contained character so as to be easily renewable, and is at the same time in intimate thermal relation with the working surface of the tool. I accomplish this result by inclosing a heating unit of the selt-containeril cartridge type within a metallic tube and casting a mass of metal around the tube. In this way an extremely simple device is obtained which is very cilicient and in which the heating' unit may be easily in spected and renewed.
In the accompanying drawing in which I have-shown my invention embodied in con- 1 should he understood that I do not limit crete form, l igrure 1 a side elevati n o the device partially broken away to sh w the interior construction; Fig. 2 is an end view of the same; Fig. 3 is a section on the line 2-3 of Fig. 1 with the unit removed: and Fig. 4 is a view of the complete device.
Rcfcrrin to the drawing. 10 re resents P! l a metal tube. preferably oi. iron or steel. having handles 11 ri idly secured at its opposite ends. Around this tube and intermediate the handles I have cast a body of tween the body and the tube.
This metalli body 12 is elongated and has two working! faces 1 and 14 which are rounded as shown. This body is ca t on to the tube so as to be absolutely rigid, and ordinarily no fastening will he required be- An electric heating unit; 15 is arranged to tit snugly within the tube so that it may be easily removed at will. This unit may he of any suitable type but for purposes of illustra tion I have shown the self-contained cartridge type which has been found very satisfactory. This unit is described and claimed in a patent to Vogel, No. 839.343, and consists of an edgewise resistance conductor l6 wound on edge in cylindrical form having both ends of the conductor 17 passing out through one end. This conductor is suitably insulated and covered with a metallic sheath 18 so as to bring it into intimate thermal relation with the tube 10. The conductors 17 are insulated from each other by insulating beads 19 and brought out through one of the handles so that electrical connection may be made therewith through pins 20 in the usual way. By this arrangcn'ientthe heat from the unit is quickly and etliciently carried to the working surfaces 13 and 14 of the iron and the unit may be easily inspected and renewed when necessary.
'hile l have described my invention in connection with a certain type of heating' device con tructed in a detinitc way, it
I a metallic tube, a mass of metal cast around the. tube intermediate its ends. and a cylinmetal 12, which may be iron or any other 1 metal having suitable thermal qualities, and i which will make a satisfactory joint with the tube. I have found that iron castupon a steel tube suits the purpose very well.
The body 12 is of a shape commonly used in i iron cast around he tube betweeh t e banshoe ironing tools although it is evident that l I l i drical heating unit slidably fitting: into said tube so as to be in intimate thermal relation therewith.
2. An electrically heated tool comprising a metallic tube having handles at opposite ends, a self-contained heating unituslidably fitting into said tube so as to be in intimate thermal relation therewith. and a mass of i dies.
3. An electrically-heated tool comprising In witness where0f, I have hereunto set an elongated steel tube having handles at my hand this 10th day of J u1y,-1908. ogposite ends, a grass of iiniln cglst aroulnd t e same interme iate sai an es, an a I self-contained heating unit within said tube LEON PARKHURST' and in intimate thermal relation therewith, Witnesses:
said unit having conductors passing through CHARLES BERGGAN.
