This invention relates to internal combustion engines, and-the prlmary objectisto provide simple, efficient, and practlcal means for insulating the crank case and oil pan against iow' temperatures and to thereby retain the lubricant at a relatively high temperature through periods when the engine is idle, and
by reason of which the oil will not congeal as readily as would otherwisebe the case, the 10- engine will start more easily," and the lubricant will be in a condition that willpermit it to be fed immediatelyto other parts of the tively insulating the reservoir and preventing the penetration or frost throughits wallai 1 am aware of'prior art devicesin which the crank case or oil pan of a motor areprovided' with auxiliary surface chambers through 25 which fluid mediums are circulated either for heating or cooling purposes, but the devices ofthat nature that have come to my attention do'not recognize oranswfer the problem with which I am concerned, as they do'not concern themselves with maintaining the previously I acquired temperature, ofthe lubricant, but rather provide 'means' for altering the lubricant temperature by; running" the: engine,
which, of course, in no way. helps to startvthe settled therein.-
engine, which is the serious objection that this device is desig'ned to overcome, at least in a large and eiicctive degree. In the accompanying drawing, which illush trates a preferred embodiment of the invention I Fig. 1 is asectional elevation taken transversely through the lower portion of an internal combustionfengine having my invention applied thereto.

This pipe 12 is provided Fig. 2' isan enlarged detail section of the Figsr3 and dare enlarged detail views of sidechambers, respectively. I v Referring to the drawing more particularly o and by reference characters, A designatesthe the drains and stoppersfor-the bottom and engine block ofan internal combustion engine 755 having a crank shaft B operating in an 011 or lubricant reservoir C formed by thercrank case D. and oil p'anE all of common'and well known construction andfarrangement.
' The oil panE'may be of standardor special construction, butiin either event is supplement'ed' by a pair of spacedplates or walls i: and 5, of similar shape: to. and forming i 'cham'bersfi and 7 witi the pan E. The pan a forming plates 4 and 5 are successively deeper.

instancefwhenit is found necessary to re plenish ithe chamber C with new and fresh oil. Itmay alsobe noted, however,zthatthe pipe also serve in the additional ca- 91 pacity asa' water'trap, as it comprises a small receptacle in the bottom of the-lubricant v chamber, and,whcn occasionally opened for j a moment, will discharge the water that has [A second'plug, 15,;having two Ieets of threads'lh and 1?, screws into integral-bean l 'ingsor sockets Band 19 of the plates l and g 5, s S ere-rer me y n :Ti o ject ofgthis'plugis'to permit draining of the 1 chainbersciand 7;shouldmoistureaccumulate,'

cured to the case D to form insulatingvchainbers 23 and 24, having a common plug 25 serving in the same capacity as the preyiously noted plug 15. It may here be mentioned that it is found preferable to treat the sur- -faces of the members D, 1 1,4, 5, 21, and 22, as by enameling, prior to being, assembled, and
this assists in maintaining the partial vacuum conditions 1n thev insulation chambers and prevents the penetration of these plate members by frost, thus further carrying forward the primary ob ects or the invention as hereinabrove set forth. 1
It is understoodthatsuitable modifications maybe madein the general design and structural detailsof the invention, as herein disclosed, provided, however, that such modificationscome within the irit and scope of the appended claims.

3. The combination with an oil reservoir of an internal combustion engine, of a pair of spaced plate members secured externally-to and forming chambers witha part of the reservoir, said chambers being normally exintheplate members and removable to-open both chambers, and a coat of substantially imperforable material applied to the plate members. i
4. The combination with an oil reservoir of an internal combustion engine, of a pair of spaced plate members secured externally hausted and sealedwhereby to maintain a partial vacuum therein, and a plug securable reservoir down through the chambers todrain the reservoir, said tubular member having a stopper at its lower end whereby it will serveas areceptacle trap for waterand sediment in the oil of the reservoir.
G.The combination with an oil reservoir of an internal combustion engine, of a pair oi spaced plate members secured under the reservoir to, form, insulating chambers there under, a tubular member extending from the reservoir down through. the chambers to drain the reservoir, and a stopper securable in the plate members ,foropening the insu latingchambers p 1 The combination with the. oil pan of an internal combustion engine, of a pair ofsuccessively deeper pan members secured under the oil pan, to form spaced insulating chambers tlierewith,said oil pan and members having contiguous flange portions welded together, and l'neans for respectively draining the oil pan and chambers. 8. The combination with the oil pan of an internal combustion engine, of a pairoi successively deeper pan members secured un-. der the oil pan, to form spaced insulating chambers therewith, said oil pan and members having 7 contiguous flange portions welded together, and a tubular drain memberextending from the oil pan through the pan members but sealed from communication with the insulating chambers.
