to The Alaska Freezer Co., Mass., a corporation of Mass., asslgnor Inc., Winchendon,
husetts 1 Claim.
This invention relates to oil burners in general but is particularly adapted for that class of burners applied to a kitchen range.
The principal object of the invention is to pro- I vide an improved pre-heating device and to provide a way of installing an electric coil for this purpose. Y
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawing, in which Fig. 1 is a plan of the base of an oil heater showing the pre-heater in accordance with this invention, and
Fig. 2 is a sectional view thereof on the line 2--2 of Fig. 1.
'Ihe invention is applied to an oil burner having a base 10 which can be provided with any desired means for supporting a series of circular or other shaped perforated walls 9 which concentrate the heat and allow for the desired circula.- tion. 'Ihe oil for the burner is carried in the burner in an arcuate groove 11 formed in a mass of so-called mud formed of clay, asbestos or other similar material, which has absorbent properties and also is a good insulator. On account of its absorbent character this body of material serves the same purpose as a wick also. This body of material is of circular annular shape and carries this annular groove in its center.
Under the annular groove is a heating coil 13 of arcuate shape. 'I'his coil is preferably of the type of the so-called Helicoil and the details do not constitute a part of this invention. Its terminals 14 are passed down through the bottom of the base, being provided with bushings 15 which rest on soft washers 16 and screw-threaded below to receive fastening nuts 17. Between the nuts and the base is also a soit washer 18 which firmly secures these parts in position.
The oil is supplied through a pipe 19 and the I means for supplying the oil from this pipe to the groove 11 is not shown herein but the heating coil is located on the base 10 and within the body of the plastic absorbent material 12.
The invention can also be carried out by em- 10 bedding the electric coil 13, in the same form as now shown, in the body of the base 10 having the part shown as occupied by the composition 12 of integral cast iron and the place for the coil cored out so that that can be put in after castl5 ing, or cast into it in the act oi.' casting.
This constitutes a very convenient pre-heater in which the coil is directly at the bottom oi.' the supply of oil to be heated and is permanently xed in position. The coil itself can be bought 20 on the market and attached in the way specified.
Although I have illustrated and described only one form of the invention I am aware of the fact that modiflcations can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. Therefore I do not wish to be limited in this respect but what I do claim is:-
The combination with an oil burner having an annular mass of absorbent re resisting material oi.' permanent form provided with an arcuate groove in its upper surface for receiving and retaining the oil to be burned, oi an arcuate electric heating coil located within the mass of said material directly at the bottom of said groove.
SEWARD W. VERRILL.
