sn nnvrnnrr REMOVER FOR semen 'rnousn si Application filed February (-2 .1925: Serial Non 7,331:

This invention relates to crank casings for internal combustiontengines, a'ndi hasfor its object the-provision of means whereby the sediment. in the splash troughs may be quickly removedztheretroin without removing the trough from; the; casing:

This objectis attainedibythe-mechanism illustrated in: the I accompanying drawing,

a For thepurposeof illustrating the-invention; one preferred; form thereof: is illustrated' in the: drawings; this form having been found 'to' give satisfactory. and reliable results, although" it 'isto be understood that the various instrumentalities of which the invention consists can be'variouslyi arranged and organized, and the invention is not limited to the precise arrangement and organization of these;instrumentalities as herein shown and described except as required by: theseope' of-the appended fclai'ms.

Of the drawings: V Figure 1 represents a section of a portion of the crank? casing? of: an internal combustion. engine; showing; one of the splash 1' troughssthereof iandnm'eans for removing-the sediment: therefrom, embodying the; principles of the' present invention; 7

Figure: 2:representsan end elevation. of suid'trough, and I Figure 3 represents a. transverse section onrlineB; 3, onrFig. 1.

Similr'. characters; indicate-likeparts throughout the several figures; of the draw- 1ngs:-

In the drawings, 101s a crank casing ha-vingta pan .11 at the bottom thereof;

Thecasinggl0, as illustrated in the-drawings,-. is adaptedto containqa. pluralityv 0-fcranks 12 of an internal oernbustion engine, one of'said cranks '12,;being shown in: Fig. 1 of the drawings as" secured. to a crank shaft 13 and having the usual connecting rod 14'; pivotally. secured .to its free end.

Beneath each crank 12 is disposedan oil trough 15. havingaicomplartment.15 adaptedctotbe? partly filledwith oil through. which the: free end OffthG-Clffillk; 12.n1ust pass as; thereby 6 thoroughly lubricatingthe bearings between the crank; shaft 13". revolves;

the: crank 12 and the connecting rod 14.

Inganother application, ofmine; Serial No; 732,741, filed August 18,-;1'9 24,-..is'sl 1own ineanswhereby each oftheroil troughs 15 may be removed from the casing; without disturbing the. other; troughs;

In some. cases it is desired-' to remove the oil troughs as seldom. as; possible-.- and. consequent-1y it is desirable: to provide}; some means coacting with each. trough whereby the-oil or sediment i in the. trough may be re moved whilethe trough remains-.-within: the casing. i 7

To accomplish this, end, eachtroug-h15 is provided withgai passage l 16 insthe bottom thereohthe lower. end of which communicates with a cylindrical chamber 17 extend-- ing lengthwise of said trough", said ;chamber 17- being closed atith'e-inner endof the trough. whilezthenuter end thereof is thread- 2 ed as at 18;a11dhas screwed. therein awclosure;19.j r 1 Within the chamber 17 is positioned a cylindrical member. 2Ohaving a depression 21 in its upper; registering with the: passage. 16 and; in' which all sediment: in. the

trough is adapted to collect.

The outer end oftheniember 20 s ene- Shape'd at .22. andhasa projection .235 extending outwardly therefrom..providedlwith a diametrioalhole 24, 5 adapted. to receive a-pin'tozassist in removing the. member. 20.-

from the chamber-17L v The come -shaped end 22 fits into. a, cavity in the. closure 19and theprojection23extends through Said, closur'e,,. all as shown in Fig; 1..

The member: has a groove25 extending endw-ise thereof into, which extends the, reduced inner" end of a screw 26 to prevent said member 20- from" rotating about its. axis. Between the inner end of the chamber 17 and the inner end ofthemember 2O i-sa tubular member 27' having;- a spring 28 therein between a partition 29 in saidltubular inemberrand the-inner, end of said chamberr20-.- v 1 Ordinarily I this springi- 28 l is; under 1; cornpressionbut when the member20 isbeing removed from. thechamber 17- the spring 28 will immediately commence'to eipand and cause the tubular member 27 to follow the member 20 until its forward end com-es into contact with the screw 26 when further forward movement is prevented.

When the tubular member 27 is in this forward position it closes the passage 16 and prevents the oil in the trough from entering the chamber 17 The rear end 29 of the member 20 is re duced slightly in diameter and fits into the forward end of the tubular member 27.

/Vh-en it is desired to remove any sediment which may have collected in the depression 21 of member 20, the closure 19 is removed, a pin or some similar article is positioned in the hole 24:, .and the member 20 is then withdrawn from the chamber 17 and cleaned.

While the member 20 is being cleaned a similar member 20 may be inserted immediately into the chamber 17 The passage 16 will be closed immediately by the tubular member 27 so that it would be possible to use the motor even while the member 20 was removed.

When cleaned the member 20 is again inserted into the chamber 17 pushing the tubular member 27 into its original position as shown in Fig. 1 and then the closure 19 is screwed into position.

This makes a very simple means whereby the sediment may be removed from the trough 15 without disturbing the trough.

This trough 15 may also be removed when it is desired to make such removal for any good reason.

This is accomplished by removing the bolts 30 extending through the flange 31 formed upon the outer end of the trough 15, said bolts being threaded normally in sockets in the casing 10.

The inner end of the trough 15 is supported on the lug 32.

By this mechanism the troughs may always be kept in condition, free from sediment, as the members 20 may be removed and cleaned as often as desired without placing the engine out of commission. The invention is particularly adapted for internal combustion engines on fire trucks which should be in condition at all times anld ready to respond immediately to any ca 1.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, 1
