'iThisrinvention relates to improvements! in multicylinder:- internal combustion. .engines and. more specifically. .it relates tov a newend improved spark plugsetting.
The" moderndevelopment ofinternal combustiorrengines has a. tendency: toward 1 increasin the number. of cylinders-which-results antincreased number of ,spark plugs. The, spark plugs have to be detached. and replaced from, time -.to time for the purpose: of cleaning. -adjusting. -.re pairing -,or exchanging-i-the :same, -.or'-. in. eeold weather it is :frequently-necessary'ito remove the plugs for: dripping-gasoline: into the ;cylindersin order .to overcome? difiicultiesfin starting theenginei If. anengine. has six. leightrtwelve or: more cylinders;.the .unscrewingv and resetting.- of: 168 011 singlegplug' is very bothersome and-requires much time. Moreovenmhe cylinderheads -which :carry the-aplugs are pftenxmade ot aluminum or other light. metal; so'tthat a considerable: amount: :of skill; care, and experience: is: necessary tiersre screwing rthe plugs; because 1 if then-same: are tightened too "strongly; the. threads1=of-'the spark plug 1 holes will wearv outuand iexpensive' :repairs al-.119 buying. :and; installing or. az-new cylinderhead willbe necessary.
Itivis, therefore,the 'main :object-"of theimresent invention to provide a; isoi-rcalled' old spark: plug: setting. byameans; TOflWhiOh two; cfour,
six; eight .ormoresplugsg whicha are: sarrangedrin 'a'row; can" be removed together i from Ethe: =cylinder block and :can: be putbackrin: placemlthout un-screwing and re-screwing eacht' single plug, and bwmeans-of 'which all said plugs can be removed andreplaced with less efiort, skill and within a shorter period of time than has been required hitherto for the removal and replacement of one single plug.
Another object of the present invention is the provision of a device of the character-described which requires but few and simple changes on the presently used cylinderheads, so that this device can be used not only on newly manufactured engines but can also be attached to any existing engines at a very low expense.
Yet still another object of the present invention is the provision of a device of the character described which is light in weight,- which requires but little space, and which is simple in construction and inexpensive to manufacture, but which is sturdy and well adaptedfor thorough usage to which such devices areordinarily subjected.
Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in V the e bodiment of the "invention described and shown" :infthe" accompanying {drawing whether withm- 'or' without Lthet scope" of -the appended claims and irrespective of other specific statementsi as .to" the"scope bfthe invention-cont'ained herein.

Similar numeralsrefer to similar parts through out theseve'r'al views.
7 Referring first .to'. Figs...1,' 2...and. 3,.'the.numeral l;- denotes. acylinder head, which is indi- *cated linedash-and-dotted lines in Fig.- 1 andin iulilines-as vertical, sectional view partially broken away .in Fig. 2. -.The main part of my sparkplug setting: is a longitudinal bar 2, which 7 maybe called a imanifold, of cast metal or the like, which. consists of flat, portions andof upwardly vextending,arch-shaped portions 3. A U- shaped --slot- 4 is 1 vertically partially extended 7 through eacharch-shaped portion 3 and is adapted for receiving a threaded bolt 5 which has a nutaand 'agwasher at itsupper. portion. Each bolt 5 hasaitflattenedlower portion through which extends a pivot pin 6- thatris' extended through lugs I: which: are welded'upon or otherwise secured to or cast as a unit with the cylinder head I. Each flat portion of the bar 2 has at its upper side a recess 8 and at its lower side lugs 9 which are in spaced relation to each other and adapted for being inserted into the countersunk portions of the spark plug holes which are in the cylinder head I. A washer I0 is below each lug 9, and if the nuts on the bolts 5 are tightened the bar. 2 and the lugs 9 will be pressed against the washers [0, so that no gas can escape through the countersunk portions of the sparkplugholes. I prefer to make the lugs '9 at both extremities of bar 2 a few thousandths of an inch, higher than the other lugs so that the same pressure will be exerted upon all washand through the adjoining flat portion of bar I 2, and a spark plug II is screwed into each of said threaded apertures in such a manner that its lower portion projects over the lower side of each lug 9 and protrudes into the cylinder in the usual manner, as may be seen in Figs. 2 and 3. Thus, the spark plugs II are screwed into bar 2, the recesses 8 being wide enough for inserting a socket wrench (not shown) around the plugs ll, so that each single plug has no longer to be screwed in the cylinder head. A
The bolts could be extended through simple vertical holes in bar 2. In this case, it would be necessary to unscrew the nuts entirely from V the bolts 5. For facilitating the dismounting and re-mounting of the bar 2, I prefer to provide each arch-portion 3 with a reinforcement and with a slot 4, and to secure the bolts 5 hingedly or pivotally to the cylinderhead l, as previously referred to. This arrangement allows a lateral swinging and disengagement of the bolts 5 from is satisfactory if pairs of spark plugs. H' areclose together as shown and asis. the case with many six and more cylinder engines, the arrangement shown in Fig. 4 may be preferred in the case of two or four cylinder engines or wheneverthere is a comparatively large distance between all plugs. According to this embodiment of the invention, the longitudinal bar is substituted by a member 2 which hasfiat extremities and an arch-shaped center portion 3, and each flat ex-.- tremity has only .one lug 9 and carries only one spark plug H. The slot 4, bolt 5 and pin 6 are arranged in the same manner as explained in the description of Figs. 1 to 3, and lugs 21 are secured to or formed as a unit with the cylinder head 2!.
While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification,
it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its opera tion may be made by those skilled in the art withoutdeparting from the'spirit of the invention.
It is the intention, therefore, to be limited only ternal combustion engines comprising a manifold which has substantially fiat portions and upwardly extending arch-shaped portions between each two of said flat portions, threaded bolts vertically extending through said arch-shaped portions and being secured to the cylinders of an internal combustion engine, and nuts screwed upon the upper portion of said bolts and adapted for pressing said manifold against said cylinders, said flat portion having at their lower side lugs which extend into'the countersunk portions of the spark plug holes of the engine cylinders, and a bore being extended through each of said lugs and through the adjoining fiat portion and being provided with a thread into which a spark plug is screwed in such a manner that the lower portion of each spark plug protrudes over the lower side of each lug, all substantially as set forth.
2. A spark plug setting for multi-cylinder internal combustion engines comprising threaded bolts hingedly secured to the cylinder head of the engine and having nuts screwed upon their upper portions, and a bar which consists of up-- wardly curved portions and of substantially flat portions having at their lower side lugs which extend intothe countersunk portions of the spark plug holes of the enginecylinders, each of said upwardly curved portions having a U-shaped slot through which one of said bolts is extended, and a bore being extended through each of said lugs and through the adjoining flat portion and being provided with a thread into which a spark plug is screwed in such 'a'manner that the lower portion of each spark plug protrudes over the lower side of each'lug, all substantially as described.
3; A spark plug setting for multi-cylinder internal combustion engines comprising an archshaped member through whose center portion a horizontal slot is partially extendedand whose lower end portions are provided with lugs adapted to be inserted into the countersunk portions'of the spark plugholes of two adjoining cylinders of an internal. combustion engine and with bores into each of which a spark plug is screwed in such a manner that the lower extremity of the plug protrudes over the lower side of the lug, a threaded bolt being ivotally secured to the cylinderhead of the engine and adapted to engage said slot, and a nut being screwed upon the upper portion of said bolt and being adapted for pressing said arch-shaped member against the cylinderhead. all substantially as described.
