Application 'June26, 1950; "Serial No." 1701442 readily arid-easilyattachedas a side entry in- '--'stallation '-to the conventional oil pan in such a manner that the' heater becomes virtually a part {of the oilpan itself. The heating cartridge -may -be readily and ea'sily'replaced with the same-ease that it can' be installed'and may be accomplished with a-=minimum of effort and manipi1lation without 'damaging or weakening -4'i-ther' theoil pan or the heating cartridge itself.
Yet another object of this invention is to provide an attachment for a crankcase oil heater which is relatively simpl in design and construction,- inexpensive; and very efficient for its intended purpose.
These, together with various ancillary objects andfe'atures of the invention which will later become apparent as the following description proceeds; areattained by the device; a pre- -ferred embodimentof which has'been illustrated by; way'of example only in the accompanying drawings wherein:
1 Figure 1 is "afragmentary side elevati'onal view disclosing a portion of an internal combustion engine, th pan of the crankcase, and the visible L-shaped bracket forming a part of the attaching means for the oil heater.
Figure 2 is an enlarged view showing a portion of the oil pan or crankcase in section, showing the heater and attaching means before the latter is finally clamped to the oil pan.
Figure 3 is a view similar to Figure 2 with parts broken away and shown in section and showing the attachment means in its finally clamped position.
Figure 4 is an exploded elevational view showing th electrical heater unit and the improved attaching means therefor with the parts separated for better presentation.
Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements thoughout.
Indicated generally at In is the engine of an automotive vehicle to the bottom of which is 4 Claims. (Cl. 21938) secured in a conventional manner an" oil pan 1 2. The side-of the 'oi1 pan is provided with-an aperture --|4 through which 'th f' heating cartr ldge I 6' extends into the interior of the oihpan tand at which position-the heating-cartridge is attached by the means to be desc'ribedhereinafter. The heating cartridge is of the --type described in the- Boger Patent l Io. '2,470;9'-72 and i includes a shell having a dielectric core thereiniaaridca heating element about the core Lvvhich. is i'communicated i with conductor wires 1' I8 extending through a conventional flexible'l cable 20.
Secured upon the shell of vthe cartridge I 62 is an enlarged shoulder I 2 22of diameter somewhat smaller than the diamet'er of the oil: pamiaperture l t, the: shoulder. being..:integral 'r-with ran externally threaded.;portion';24;-ittbeingriunderstood that the Lcable1-20 'extendsflthrough'is'the :YAn L-shaped: bracket 4 2a .is gprovidedahaiziiig one leg. portion thereof which: includes :an
: aperture 32-slidably receiving the.cab1e:-20 "and disposed in front of the; deformable washerx26.
.In use, the; cartridge I6 with the attached shoulderv 22 and reduced threaded"extensi'on' 24 is positioned in the interior of the oil pan through the aperture M with the major portion of the cable 20 extending exteriorly of the oil pan. The leg 30 of the L-shaped bracket 28 is pressed against the side of the oil pan I2 and an internally threaded nut 34 is slipped on the cable 20 and made to engage the reduced threaded extension 24 of the shoulder 22 so that when the nut 34 is tightened into the position shown in Figure 3, the lead washer 2'6 is compressed into and over the hole as at 36 sealing the heater unit so tightly in the oil pan that for all practical purposes it becomes a part of the oil pan. The L-shaped bracket 28 also assists in properly supporting the heater within the oil pan. This form of attachment does not damage or weaken either the heating element or the oil pan and retains the heater therein in such a manner that substantial jarring of the automctive vehicle will not loosen the heating element in the oil pan. The other leg 33 of the L-shaped bracket includes an aperture for receiving a portion of the cable 20 as shown clearly in Figure 1, the cable of course being made to extend along the side of the motor, around the radiator 40, and to be connected to an outlet 42 through the grill M for handy connection to a 110-volt electrical circuit.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.
Having described the invention, what is claimed as new is:
1. In combination, a liquid containing pan having a flat side wall with an opening therein, an electrical heating unit situated in said pan and embodying an integral shoulder having a flat face in parallelism with the inner surface of said side wall, said shoulder being of a di ameter less than the diameter of said opening,
,a reduced hollow screw-threaded stud project-v ing from the center portion of said shoulder and extending outwardly through and beyond said opening, a' deformable packing ring encircling and mounted on said stud and plugged into said opening and of a diameter slightly less than that of the opening and greater than that of the shoulder, and non-compressible nut retained -means mounted on the outer end of said stud.
bridging and covering the outer side of said opening and having firm backing contact with the adjacent side of said packin ring.
2. In combination, a liquid containing pan having a flat side wall with an opening therein, an electrical heating unit situated in said pan and embodying an integral shoulder having a flat face in parallelism with the inner surface of. said side wall, said shoulder being of a diameter less than the diameter of said opening, a reduced hollow screw-threaded stud projecting from the center portion of said shoulder and "extending outwardly through and beyond said opening, a deformable packing ring encircling and mounted on said stud and plugged into said opening and of a diameter slightly less than that of theopening and greater than that of the shoulder, a flexible current conducting cable electrically connected with said unit and extending outwardly through and beyond said stud, an L-shaped bracket embodying one limb apertured, fitting removably on said stud and spanning said opening and having abutting con tact with said packing ring and outer surface of said side wall, an assembling and clampin nut screwed on said stud and abutting and retaining said limb in place, and the remaining limb having an aperture andthe adjacent portion of said cable being threaded through said opening.
3. The structure defined in claim 1, wherein said packing ring is of a cross-sectional thickness greater than the cross-sectional thickness of said side wall.
4. For use in heating oil in the oil pan of a crankcase construction wherein the pan has a less than that of the opening andgreater than that of the shoulder, and non-compressible nut retained means mounted on the outer I end of said stud bridging and covering the outer side of said opening andhaving firm backing contact with the adjacent side of said packing ring.
