UNITED STATES PATENT OFFICE.
ROBERT JOHN MARKLE AND CARL LOUIS FALSTREM, or PARRY SOUND, oNTARIo. CANADA; SAID FALSTREM AssIeNoR or nI-s INTEREST, TO HARRY NEWTON HOQKEN, or TORONTO, ONTARIO, CANADA.
SPARK-PLUG ATTACHMENT.
Application filed August 13, 1920. Serial No. 403,226.
To all whom it may concern:
Be it known that we, ROBERT JOHN M RKLE and CARL LoUIs FALSTREM, both subjects of the Kin'g of Great Britain, residents of the town of Parry Sound, District of Parry Sound, Province of Ontario, inthe Dominion of Canada, have invented certain new and useful Improvements in Spark-Plug Attachments, described in the following specification and illustrated in the accompanying drawings, that form part of the same.
The principal objects of this invention are, to improve the operating conditions in spark plugs which will increase their efficiency in producing a hot and virile spark and will greatly reduce if not completely eliminate the carbonizing of the terminals. The principal features of the invention consist in providing a cooling chamber around the plug and in providing a gas chamber around the terminals which will direct a flame into the cylinder.
In the drawings Figure 1 is an elevational view of our improved plug attachment.
Figure 2 is'a vertical sectional view shown attached to a cylinder.
It is a well established fact'that the inn-r endof the spark plugs of internal combustion engines is subjected to the hottest temperatures which results in damage to the plug and it is the principal aim of this invention to protect the plug by dissipating the heat at this point.
In the form of the invention shown in the drawings the plug 1 is threaded into the outer end of a tubular shaped member 2 which is provided with a threaded end 3 corresponding to the plug thread.
A chamber 4 is formed in the member 2 which tapers inwardly. This chamber is arranged above the cylinder head 5 and en closes the sparking points. The oints are thus protected against the splashing of oil thereon and carbonizing of same is reduced to minimum.
A shoulder 6 is formed on the member 2 adjacent to the inner end and the perimeter of same is threaded, preferably with a fine thread.
An annular flange 7 is formed on the up per end of the member 2 below the nut shaped portion 8.
Surrounding the memher 2 is a circular shaped casing 9 which threads onto the threaded shoulder 6 and the flange 7 fits within a recess 10 in the top of said casing and abuts a gasket 11 forming a water tight casing around the member 2.
Suitable spannernotches 12 are formed in the top of the casing 9 to enable the members 2 and 9 being screwed tightly together.
Inlet'and outlet nipples 13 and 14 are secured in the wall of the casing 9 to which water circulation pipes are connected so that a constant flow of water will be maintained -through the casing. This water jacket surrounding the chamber 4 dissipates the heat formed around the spark plug and produces a highly desirable and advantageous ignition condition.
The V enters t as compressed within the cylinder e cham er.4= and is confined closely around the points producing excellent ignition conditions.
The confined gas when ignited projects a jet of flame into the cylinder which ignites the main charge in a very efi ective manner and any carbon tending to form around the opening to the chamber is very efi'ectively blown into the cylinder.
. What we claim'as our invention is:
wat sldes o circulation pipes secured to opposite said casing.
