ELEUI'RIC HEATING DEVICE FOR BURNING DRYING- PURPOSES.
Application and December 14, 1922. Serial No. 606,852.
To all whom it'may concern Be it known that 1,, WILLIAM Cooran, residing at 7 St. Thomas Road, Huddersfield, England, have invented an Electric Heating Device for Burning and Drying Purposes, of which the following is a specification.
This invention relates to an electric heating device that is primarily intended for re- .to be heated and for bringing the heating element in close proximity thereto, so that when such element is heated to the required temperature by an electric current under the control ofthe operator such heat is radiated directly on to the surface to be treated.
In the accompanying drawings Fig. 1 is a pl n, 2 an elevation partly in section, and Fig. 3 an' inverted plan of an electric heater constructed in accordance with this invention.
Fig. 4 is a plan and Fig. 5 a section of ,an electric heater for use in connection with Fig. 6 is, an end view and ig. 7 a side view of an electric heater for treating flat and curved surfaces.
Fig. 8 is a section and Fig. 9 an end view showin a modified construction of'heater. 'Aind icatesthe resistance element, and B the holder.
The resistance element A comprises a number of wire coils supported upon an in- .sulating backing b which may be constructed from micag, fire clay, rcelain or other suitable refractory insulating material. The
insulating backing b is secured to the holder B by clamping plates b and screws 6 and interposed between the backing b and the holder is an asbestos lining b. The opposite ends'of the heating element are attached to terminals 0 which are adapted to enter metal sockets a that are,clam d between two portions of an insulating older'a by The sockets a are connected by wires a with-a switch a that is mounted in a casing or a. handle a and is connected to a length of flexible cable a that is attached to a plug a or other electric fitting. The. socket holder a is attached to the switch casing 11 by a bolt and thumb screw a so that it can be swivelled in rela-- tion thereto as shewn in Fig. 3. The modification shewn in Figs. 4 and 5 is provided with two separate heating elements A A for circuits of two different Voltages. For example the heating element A may be applicable for use in connection. with a 100 volt circuit and the heating element A be applicable for use in connection with a 200 volt circuit. When the width of the holder is increased it is provided with a micanite or other suitable stay I) which is secured between two adjacent clamping plates b and prevents the heating element A from sagging and coming in contact with the surface to be treated. In the modification shewn in Figs. 6 and 7 the heating element A is mounted on an ap roximately V shaped backing b surmounted by correspondingly shaped sides or flanges bf so that it can be moved over flat surfaces or be inserted into grooved, or moulded surfaces. In the modification shewn in Figs. 8 and 9 the backing b is moulded from a suitable refractory material with grooves b for the coils of the heating element A. It is formed at the back with a rib b" which short circuiting and it is secure to an aluminium or other. metal holder B by clamping plates 1) and screws b, a lining. I) of asbestos being interposed between the backing and the holder.
, What I claim as my invention anddesire to] secure by Letters Patent in the United means for passing an electric current through the resistance element and the said pair of connections.
2. An electrically heated hand tool as set forth in claim 1, and having the socket revents holder pivoted to the handle and provided I with means for clamping it in various positions to the handle. a
3. An electrically heated hand tool co rising in combination a handle a metal casmg attached to said handle a clamping device constructed from insulating material attached to sald casing, two metal connecting devices mounted in said clamping device and metal contacts attached to said backing .ar-
ranged'dn electrical connection with the resistance elementand adapted to make a detachable connection with the metal connecting devices carried by the clamping device, a metal casing for supporting the backing and arranged to present the resistance element in suitable'proximity to the work.
4. In an electrically heated hand tool, a resistance element, a backing constructed from refractory insulating material for supporting said element, metal connecting devices carried by said backing and electrically connected with the resistance element, the said parts comprising a single unit, a metal casing for carrying'said unit and means for enabling the unit to be inserted and removed from the casing. i
5. In an electrically heated hand tool a plurality of resistance elements, a backing constructed from refractory insulating material for supporting said elements, terminal contacts attached to said backin and elec-' trically connected with said e ements, a metal casing for carrying said unit and provided on the back with sup orting legs and on the front with detachab e plates, on removing which the resistance elements, backing, and terminal contacts can be inserted and removed as oneunit.
6. In an electrically heated hand tool the combination of a heating element, backing, casing and terminals arranged to constitute one unit; and a handle, switch, flexible connection and terminals another unit, the terminals on the respective units being' ar ranged to make a plug and socket joint with one another.
7. In an electrically heated hand tool a unit comprising a resistance element, backing, metal casing and terminals, another 'unit comprising a tubular handle jointed holder, switch, flexible connection and ter minals, the said terminals being arranged to make a plug and socket joint with, one another and the handle being arranged at an angle in relation to the resistance element.
In testimony whereof I aflix my signature. 1
