ROY w. BROWN, or AMSTERDAM, NEW YORK;
ELEo'rRIo HEATER.
Application filed October 22, 1908. Serial No. 459,097.
To all whom it may concern:
Beit known that I, ROY IV. BROWN, a citizen 'of the United States, and a resident of Amsterdam, New York, have invented a new and useful Improvement in Electric Heaters, of which the following is a 'speci-' fication.
M invention relates to a heatin device scribed 'in the following description and claimed'in the claims.
Referring to the drawings, Figure 1 is an illustration of the heat unit and its application- Fig. 2 shows a longitudinal section of the heat unit. Fig. 3 is a cross sectional yiew of device illustrated in Fig. 2. Fig. 4 s also a cross sectional view of device shown 1n Fig. 2. Fig. 5 illustrates the application of the heat unit to a receptacle. Fig. 6 illustrates a modification of the heat unit.
' 1, Figs. 1 and 2, is the body ofthe heat unit. This body is composed entirely of Portland cement. It may have any desired cross section. The cement body, as shown in the drawing is a square prism. In the prism there is embedded an electric heat wire 2 capable of producing and sustaining a very high temperature. It is formed into a helical coil. It has leads 5, 5 connected to the terminals which connect it to conductors contained in the cable 13. In the center of the prism is a reinforcing rod 7 which greatly strengthens the cement body and prevents the same from cracking. The rod is of iron and passes through the length of the prismatic body and binds its parts together. A piece of slate 8 conformingto the shape of the cross section of the unit is located at the outer end of the cement body and prevents chipping or breaking of the corners and forms a firm hard protector as well as an insulator. 6 is an asbestos strip also conforming to the shape of the cross section of the cement body. It constitutes a heat insulator for. handle as well as an electric insulator.
9.isa-handle which is located on the end of the prismatic body. The handle, cap and asbestos insulator are secured. together as well asthe partsof. cement body and maintained in. position by the reinforcing rod 7 which operates to bind them together. The
rod has enlarged heads 12, 12. I
The prismatic body is-formed by inserting the reinforcing rodin a. cylindrical mold and packing or inserting the cement around the reinforcing rod. After the cylindrical cylinder. of cement thus formed about the rod is hardened it isremoved from the mold and an electric heating wire capable of sustaining a high temperature is wound around the body of the cement forming a helix. The cement body is then inserted in a second mold having the desired shape and the mold receptacles and the contents thereof heated. It may be used as a warmer for the feet, the
same as a warming; pan is used, or it may be used .for the same purpose as the hot water bottle is used. In Fig. 5 I have shown a receptacle in .connection with which the heater may be used for heating the contents of the recep-- tacle without coming in contact therewith. A coppered tube or prism 10 having preferably the same shape as the heating unit is placed in the receptacle and through two holes 11 located on each side and near the bottom of the receptacle. The ends of the prism 10 are clamped or crimped so as to inclose the edges of the holes and securely fasten the hollow prism in the receptacle. The unit is inserted in the copper tube or case when it is desired to heat the contents of the receptacle.
In Fig. 6 I have shown a unit inserted in the receptacle. and in contact with the contents of the receptacle. Here the unit is bent so as to more or less conform to the shape of the wall and the It may be used for heating any- 3 The embodim'ent'of my. invention may be made in any shape or of any construction so that a simple cheap and yet eficient heater of, an oblong cement body, slate located at one end of the said cement body, asbestos located at the other end of said body, a handie, a rod for tying-the said parts together andembedded in said cement body, an electri'c heater helix surrounding the said rod andembedded in the said cement body.
2. In an electric heater, the combination of, a reinforced cement body, a helicoidal heater embedded in the said cement body, a metallic prism surrounding the said cement body, a receptacle having holes for receiving the said prism.
3. In an electric heater, the combination of, a reinforced cement body, a heliooidal heater embedded 1n the said cementbody, a
metallic prism surrounding the said cement body, a receptacle having holes for receiving the said prism, the said prism being securely fastened in the said holes and passing through the interior of the said receptacle. 4. In an electric heater, the combination OK on of a cement body an iron rod passing through the said cement body, heads located at one end of the said cement body, one of said heads being made of slate and the other of said heads being made or asbestos, a handle,
the said parts being joined together by the said rod, wire wound around the said cement body, pure Portland cement covering the said wire.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
