ELECTRIC HEATER'.
To all whom t may concern.'
Be it known that we, WILLIAM ANDREW MORRISON and FREDERICK DELIMER LAKE, both of the city of St. Catharines, county of Lincoln, Province of Ontario, Canada, have invented certain new and useful Improvements in Electric Heaters, of which the following is the specification.
Our invention relates to improvements in electric heaters, and the objectof the invention is to devise a simple, cheap, compact, highly efficient form of electric heater in which the heating element may be quickly and easily removed for the purpose of repair without damage to any part of the heater and it consists essentially of the following arrangement and construction of parts as hereinafter more particularly eX- plained. 1
Figure 1, is a side elevation of our heater.
Fig. 2, is a vertical sectional view through Fig'. 1.

Fig. 4, is a cross sectional view in line lW-(g/l 2.
Fig. 5, is a cross Sectional View in line m277-y27 2- Fig. 6, is the end of the heater looking at the bottom.
In drawings like characters of reference indicate the corresponding parts in the various figures.
1 indicates the outer casing which is cya cross sectional view in line lindrical in form and which is provided at its upper end with a head 2 having an outlet orifice 3 from which leads the discharge pipe 4. At the lower end the casing 1 is provided with a head 5 having a circular orifice 6 around the edge of which extends a rabbet groove 7. 8 is an inner'cylinder provided with a closed upper end 9. The lower end of the cylindrical casing fits in the rabbet groove 7. The interior diameter of the casing corresponds to the diameter.
of the orifice 6. A space 10 is formed between the outer and inner casing through which the water to be heated passes t o the outlet pipe 4. 11 is an inlet pipe which 1s secured in the orifice 12 which is formed preferably in the reinforced portion 13 of 'the casing 1. 14 is a heating element. The
' heating element 14 comprises a central core 15 which is preferably formed of soap stone or other material adapted to absorb and re- Specication of Letters Patent. Patented 111211-,l 529, 1921.

tainheat to a maximum extent.;v The core 15, as shown in the drawing, ycomprises a circular head 16 at the lower end Vfrom which extends centrally a stem portion' 17.
18 is an enlargement .which is formed above the stem 17 and integral-therewith. The enlargement 17 is provided with-lon itudinal grooves 19 spaced arrequal distance apart around the surface of thev enlargement. Above the enlargement4 18 is formed' a reduced portion 20. Above the reduced portion 2O is another enlargement 21 similar to the enlargement 18 providedwith longitudinal grooves 22 in alinement with the longitudinal grooves 19. Above the enlargement is another reducedportion 23 similar to the reduced portion 2O andabove the reduced portion 23 is anotherenlargement 24 provided with longitudinal grooves 25 in alinement with the grooves 19l and 22' of the enlargements 18 and 21. kBetween the enlargements 21 and 24 the reduced portions 20 and 23 are provided outwardly eX- tending annular flangesl 26 and 27. The
In case of'repair it will be readily seen that all that isnecessary to do is .to give the closure 32 a slight turning movement when it may be withdrawn from .the end of the casing 1. When this is completed the heating element 14 may be slipped from the interior of the casing, repaired and slipped back into position, the closure 32 being again placed in position. From this description it will be seen that we have devised an electric heater which is cheap to construct and in which the heating element may be gotten at, at any time for the purpose of repair, in which the current consumed will be economzed and which will maintain its temperature 'for aV considerable period of time after the current has been turned oil'.
What we claim as our invention is-- A heating element-comprising a core of heat absorblng and retaining material provided with a plurality of grooved enlargements each having the grooves thereof registeri'ng withthe groovesof adjacent enlargements, flanges between said enlargements provided with apertures correspond- Y ing in number and plosition to said grooves, t e core passing through the said apertures and dlsposed in said grooves.
