D. BUSHBY CARBON REMOVING DEVICE iled April 2o'. 1921 Patented Mar. 24, 1925.
UNITED STATES DAVID BUSHBY, oFUnEnnLEsToN, SASKATCHEWAN, CANADA.
CARBON-REMOVING DEVICE.
Application filed April 20, 1921. Serial No. 462,909.
To all whom t may concern.' Y Be it known that I, DAvi) BUSHBY, asubv ject of the King of Great Britain, residing at Keddleston, in the Province of Saskatchewan and Dominion of Canada, have invent-ed certain 'new and useful Improve mentsv in Carbon-Removing Devices, of which the following is a specication.
The present invention relates to carbon removing devices applicable to oil, gas, or other internal combustion engines and is particularly adapted to prevent sticking of the valvestem or clogging of the valve on its seat, by carbon deposits. f
Inoil, gas, and otherinternal combustion engines there is, necessarily, considerable carbon deposit on and about the exhaust valve stems and valves or valve seats.. On the Stems this deposit soon forms a heavy gum which causes the valve stems to stick tight in their bores. On the valves and valve seats, its accumulation soon causes imperfect closure of the valve, with consequentleakage. Every time a valve stem sticks, the engine must be stopped and the stem freed, and whenever'k there is leakage from imperfect valve seating there is yloss of power. The main Objects of the present invention are to completely avoid these objections by automatically removing all carbon as fast as it is deposited, so that it can notaccumulate. This is done automatically, through the operation of the engine.' Furthermore, no change of any kind is required in the pres-y ent structure and no arts are added or inserted which in any egree alter the operation of any existing parts, by actual engagen ment or cooperation with such parts.
In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application. Throughout the several figures of the drawings, like reference characters designate the same parts in the several views.
In the drawings:
Fig. I isa view of the invention as applied horizontally to an oil engine;
Fig. 2 is a fragmentary view of a ycylinder section of an engine, showing the valve and valve stem, with the preferred form of the invention applied; and
Fig. 8 is a like view of a modification.
In the drawings, the invention has been illustrated as-applied to the valve stem of a gasoline or similar engine, with the valve operating vertically except in Fig. 2 where it is shown applied to an oil engine, and operating horizontally. It is to be understood that the drawing illustrates only two varrangements and that the device is fully Vapplicable to valves disposed and operating inany direction or osition, and, of course,
Vthat it is fully applicable withoil, gasoline,
and all internal combustion engines 1n which, during operation, there is an appreciable carbon deposit.
There arevarious forms in which the de- 'vice may be made and several ways in which it may be applied and operated. In the drawings, two slightly different constructions are shown. Preferably', the device comprises a ring l adapted tofit loosely on the -valve' stem between the Vinner end of the valve stem bore and the valve itself. Or, as in Fig. 3, several rings l may be used. The slight space between the ring and the stem permits the ring to rattle or hammer against the valve stem, as the stem rapidly reciprocates during the operation* of the valve. The reciprocations are both rapid and sudden. The resulting rattling of the ring causes a decided hammering effect on the stem. This-imparts a rapid jarring of the stem and its valve at every longitudinal movement of the stem. The result is that all carbon particles, as rapidly as deposited, are immediately j ari-ed from the stem and valve, so that it is kept free and all sticking of the stem or uneven seating of the valve are avoided. v
Vhile the device has been illustrated in Fig. 1 as a ring, it is evident that a non-cin ycular link, convolute ring, or other form of element may be equally well used provided that it is loose on the stem and so disposed as to give the same hammering or jarring effect as the ring. Of course, several elements may be used, as in Fig. 8. And likewise, these several elements needrnot all be alike. One may have one form and another, another form.
Changes may be made in the construction, arrangement and disposition of the several parts of the invention, within the scope of the claims, without in any way departing from the field and scope of the invention, and it is meant tov include all such within this application, wherein only preferred forms f have been disclosed by way of illustration.
Having thus described my invention, what I claim and desire to protect by Letters Patent is:
1. In combination With the reciprocating stem of a valve, `a member loosely mounted thereon and adapted to jar the same as it reciprocates.
2. In combination With a movable valve stem, means for jarring the same during operation to remove carbon deposit therefrom. 1 4 y 3. In combination with amovable valve stem, means for automatically jarring the same durin operation to remove carbon deposit there rom. a y
4. In combination With a movable valve stem, means mounted thereon and actuated by fthe movement thereof to jarr said stem and m'aintainit free of .carbon deposit.
5. In combination with a movable valve stem, means slidably mounted thereon and actuated by the -movement thereof to j'ar'r said stem and maintain it f'ree of carbon deposit.
6. In combination With a movable valve stem, a ri'ngldosely mounted thereon and ,actuated by the movement thereof to stri-ke against vand jarr said stem and maintain it free of `carbon deposit.
7. A carbon removing device for internal combustion engines comprising, a rapidly 'reciprocable valve stem, and a member loosely mounted thereon and spaced therefrom, said member being engaged and actuated by 'said stem as it reciprocates, thereby causing said member to pound ,rapidly aga-inst the stem and jar itto dislodge accumulating carbon.
8. A. carbon removing device for internal combustion engines comprising, a rapidly reciprocable valve stem, and a metal ring loosely mounted concentrically thereon and spaced therefrom, said rin-g being engaged am actuated by an sam a a faipacaes, thereby causing said member to pound rapidly against the .stem Yand jar it to dis-v lodge adcu'mulating da-rb'on. I 9, The combination with an internal comb'stifon engine having a valve provided with a guidedhstem, `of a means: for preventingr the formation of carbon on the valve stem, consisting of a member vlooselyumounted on the stem ,between the valve :portion the stem guide andfre-ely movable Alaterally 'and vertically thereon indepei'idently of the movement of Vthe valve..V I
10. The combination with an internalcom- 'bustion enginehaving a valve `'opening and Va valve stem guide, a xf'alveclosing said opening and having a stemguidedin s'aidguide, and aming-like member loosely mounted on the valve stem betvveen the valve portion and 'the stem -igui'de and freely movable laterally and verticallythereon independently of Athe movement of the valve for removing "carbon therefremll. The 'combination with an internal 'combustion overhead valve engine having lan exhaustjopening and4 a val-ve stern guide, a. reciprocal valve controlling *said vexhaust opening, and aNring-lik'e` member. loosely mounted on the valve stem betvveen the valve portion andthe stem guide and freely movable laterally i and verticallytfherehon independently of themovement of the valve for removing the carbon therefrom.
In testimony` whereof, I4 have signed "my l name to this specification in the presence of two subscribing witnesses.
