ELECTRIC HEATER FOR CRANK CASEEE.
Application filed March 27, 1925. Serial No. 1%,814.
My invention relates to improvements in an electrical heating device, forheating the oil in the crank case of the internal combustion engine, in an automobile.
The important objects of the invention are to provide for the correct amount of resistance; the proper heating of the oil, with the small consumption of current: and to provide a device of the above mentioned charac ter which may be used witha 6 or 12 volt battery. v v
Other objects and advantages of the invention will he a parent during the course of the following escription.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same.
Figure l is a side elevation of the heater,
Figure 2 is a central longitudinal section through the same, and,
Figure '3 is a transverse section taken on line 3-3 of Figure 2.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the crank case of an internal combustion engine. I drill a hole 6 through the crank case 5, preferably below the oil level. The heater embodies a preferably cylindrical tubular bodyportion 7, formed of metal, such as iron or any other suitable material. One end of this tubular body portion is screw-threaded, as shown at 8, for engagement with a contact-cap 9, preferably formed of brass. The opposite end of the tubular body portion 7 is also screw-threaded for engagement with a reducer or coupling 10, having its outer end internally screwthrcaded for receiving a bushing 11. The
The bushing 11 may be adjusted longi-v tudinally with respect to the reducer or coupling 10, by turning the bushing therein, and this bushing carries a tubular. insulator 13,
having a shoulder i l, engaging the inner end of'the bushing ll, as shown. This insulatin'p: sleeve is preferably formed oi? porcelain, and receives a contact elementlh, passin therethrougzh. This contactelernent is pretcrably formed of brass. The contact element 15 is provided at its inner end with a head 16, while its outer end is screwthrcaded. for engagement with a nut 17, by means of which the contact element may he clamped to the insulating sleeves The head 16 is provided with a conical or beveled recess l8, for receiving the conical. or beveled end 19, of a resistance-element E20. formedof-carbon. The opposite end 21 of this resistance element is conical orbeveled, and tits within a conical or beveled recess 22, formed in the contact cap 9.
An important feature of the invention is the use of the carbon resistance element 20, with the conical or beveled ends, engaging within the conical or beveled recesses of the contact elements 15 and 9. This permits of the proper regulation of the current, and the proper regulation of the resistance.
In operation, the element 15 has electrical connection with one side ofa source of current. the opposite side of which is grounded to the crank case 5. It is thus seen that. when the circuit is closed, the current will pass through the resistance element 20.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing fromvthe spirit of my in vcntion or the scope of the subjoined claim.
Having thus described my invention, what I claim is:
An electrical heater comprising a tubular body portion having its opposite ends threaded. said tubular body portion being provided with a flange near one threaded end, a contact cap engaging): one threaded end of the tubular body portion and having electrical contact therewith and provided with a conical recess, a tubular coupling engaging the opposite threaded end of the tubular body portion and adapted to clamp the same a SEPPQMB emengei nehveen it and said a Benshing having screwthreadetl engagel em within the outer end 0f @he ceupiing and longitudinally edg'zgstable therein, a \tnbuinr insulator carried; Within the bushing, a comment eiement arranged zubnfiar insulator anCk having a,
' umen eenieal recess, and; n carbon resistance element extending longitudinally Within the tuibnlar body portion and having conical encls engaging within the conical recess.
In testimony whereof I affix my signature.
