vented certain new and useful Improvements in Valve-Plu Removers, of which the following is a speci cation.
rl`his invention relates to a valve plug 1exnover, adapted. particularly for the insertionl and removal of valve plugs in .automobile engines, which plugs are employed to close the ports in the engine head, through which the valves are accessible.
These valve plugs are threaded in the port openings and are themselves threaded to receive the spark plug or priming cup), the valve plugs receiving the .spark plugs emg arranged above the inlet valves and the valve plugs receiving priming cups being arranged above the exhaust'valves. utside of the independent construction of these valve plugs for the reception of the spark lugs and priming cups, the valve lugs are i entical and arevdesigned to be t readed into the engine head to maintain a sealing connection, therewith. llt is necessary to remove these valve plugs to gain access to the valves, and this is ordinarily an infrequent operation, the valve, plugs will become so tightly seated thrpugh continued-reheating and trust that their removal is a matter of extreme diculty. Flurthermore, in the application ofthese valve plugs, it is highly desirable that they be seated to avoid all possibility of leakage and this requires the application of some considerable power in nally drawing the plugs downto a sealing position.
' Various tools have been suggested for the removal vof these valve plugs, and these tools have, as a rule, proven unsatisfactory for the reason that -they are liable under the f application of the necessary power to slip out oconnection with the recesses in the valve plugs. rlhis has been recognized as such a disadvantage of the tools new on the market for this pur ose, that ordinarily the mechanic in remove or nally applying the valve plugs will use a tool such as a screw l'driver or the like and turn the plugs by a hammer blow on the screw driver with the end of the screw driver engaged in the plug recesses in succession, This method of applylng and removing these plugs, which is the one usually employed by most mechamcs, soon results in marring the square edges of the plug recesses, and thus even thev best type of tool heretofore oifered for this purpose would therefore be of little utility as the engaging portion of the tool would ride over these rounded or marred recess edges under the application of power.
t 1s the object therefore'of the present mvention to provide a tool by means of which the valve plugs may be. removed and applied no mattei-whether the edges of the recesses may or may not lbe marred 'or rounded, the improved tool being constructed for a relatively fixed relation with the plug mdependent of the connection between the tool and recesses of the plug, there being additionally provided a member which may be conveniently applied to the tool proper after the latter has been connected w1th the plug, this member being designed to engage in the recesses of the plug to thereby permita turning operation of the tool to similarly turn'the plug.
The invention is illustrated in the accompanying drawings, in which: Fig. 1 1s a broken perspective view, showing an englne head provided with a series.v of valve plugs, the improved tool being shown in cooperative relation with oneof said plugs; i
Fig. 2 is an enlarged brokenverticallsectional view partly in elevation, one end of the tool being shown in connection with a valve plug; and
and valve plug, the parts of the tool being shown separated.
A tool of this application is designed to cooperatewith port plugs 1, which plugs have a reduced lower portion 2 exteriorly threaded at 3 to cooperate with threaded openlngs 1n the engine head 4:. The plug is interiorlv threaded at 5 with this opening of a diameter in some plugs to receive the usual spark plug 6, and in other plugs to receive the usual priming cup 7. rllhe plug further provided with an 'upstanding ange 8 formed with diametrically opposed recesses 9, the interior diameter of the harige being such as to previde an abrupt SliA shoulder 10 inwardly of ythe flange and beyond the threaded opening 5. The plug .1s circumferentially enlarged above the threaded portionv 3, providing a shoulder 11 toI overlie the engine head, there being usually provided a circular gasket resting between this shoulder 1l and theengine head, and acting to seal the juncture between the valve lug and head' when the plug 1s 1n place.
hese plugs are applied and removed through the threaded connection 3 wlth the engine head, and after the plugs have been in position for some time, they become so intimately connected with the engine headr as' to be almost impossible of removal with the ordinary tool. Furthermore, in initially applying these valve plugs, it is necessary to seat them very tightly in order to prevent leakage and this also requires the application of considerable ower.
The improved tool or this purpose comprises a bar 12 of appropriate length Jformed at each end with a cylindrical portion 13,
and be ond the cylindrical portion with a reduce threaded extension. As previously stated, the valve-plugs have their openings "5 of different sizes for receiving the spark plugs or priming cups, and as the present tool is designed for cooperation with the 30 valve plugs 'of an engine, one of suchV threaded projections as 14 will be of a sizev to cooperate with the spark plug openingof thevalve plug, while the other projection as 15 will be of a size to cooperate'with theA 36 priming cup opening of the valve plug.
These projections 14 and 15 are exterrorly threaded to cooperate with the threaded openings interiorly of the valve plugs, the sin le tool thus providing for engagement wit both sets of valve plugs of the engine. The cylindical portion 13 at each end of the main'body 12 ,is of slightly less diameter than the interiorof the flange 8 of the port plug, that end of the cylindrical portions 13 or 14, from which the threaded projection extends, roviding al shoulder 16,
which when the too is threadedly connected with the particular valve plug bears square- 1v upon the shoulder 10 of such valve plug.
- rlhe projections 13 of the tool proper are vformed' with diametric openings 17, of noncircular form, such openings being shownv square in cross-section.l A lock-bar 18 of a size to slidably lit in either of the openings 17 forms a part of the tool proper, this bar being of such length that it will extend in both directions beyond the outer surface of the cylindrical portions 13 of the tool, and
in such extended portions, as, at 19, Fig. 2,
00 will engage yin a pairv of diametrically opposed recesses 9 of the valve plug. s It is of course understood that the bar 18 is of a size to more or less snuglyv fit said recesses 9, and that as the tool is connected with the plug te through a threaded connection, such tool mamas may be turned to cause the bar 18 to cooperate with either pair of diametrically opposed notches 9 ofthe valvelug. A set-screw 20 is arranged for threa ed cooperation with each cylindrical portion 13, this set-screw beingd'esigned to engage the lock-bar 18 when the 1atter is in position and prevent accidental movement of the lock bar during operation of the to'ol. The position of the set-screw is at approximately right angles- .of the spark plug or priming cup therefrom.
The tool is screwed into place until the shoulder 16 practically en ages the shoulder 10 or so that the articul the tool will be allned with a pair of diametrically 'opposed notches 9 of the valve plug. The lock-bar 18 is then passed through these notches and openings 17 with the'ends of the lock-bar resting in the op-f posed notches, as clearly shown in Fig. 2. The set-screw 20 may then be tightened to prevent accidental movemen of the `lock bar, and the tool proper will be then turned to corrspondingly turn the valveplug(v To provide .for convenience in operating the tool, the'central portion of the body is formed with a non-circular portion 21 adapted to receive a wrench, this portion 21 being also formed with an opening 22 to re-.
movably receive a rod 23 for convenience in turning the tool. For ordinary purposes, the tool may be conveniently operated through the use of rod 23,' though where unusual power is required for theremovalL of the plug, a wrench of appropriate length to give desired leverage may be appliedrto the portion 21 for turning the tool.
It is to be particularly noted that the improved tool is positively connected with the valve plug through the threaded connection therewith; and that hence so far as -independent longitudinal movement is concerned, the tool proper and valve plug are inseparable. The use of the lock-bar serves merely to connect the tool and valve plug ar opening 17 ot against independent rotary movement, so
that any rotation of the tool will correspond'- in ly eil'ect the valve plug. As the toolis` he d against independent longitudinal movement with respect to the plug, it follows that the locking bar 18 will serve to turn the plug no matter what the condition o' the edges, of the notches 9 may be, for as longas'thesev l notches exist as such, the locking bar is boundto exert a turning influence on the reame@ plug in the turning of the tool, as the tool cannot move longitudinally with respect to theplug owing to the threaded .connecuon between the tool and plug.
