UNITED STATES PATENT OFFICE.
GIRARDUS G. NAUGLE, OF YORK, PENNSYLVANIA, ASSIGNOR T0 CARLTON L. HOFF,
0F YORK, PENNSYLVANIA.
UNIVERSAL SPARK-PLUG TEs'rEB.
Application filed May 4, 1928. Serial No. 636,601.
To all 'whom t may concern:
Be :itv known that I, GTRARDUS G. NAUGLE, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania,l have invented certain new and .useful Improvements in Universal Spark-Plug Testers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to a spark plug tester and has for its obj ect the provision of a tester which will permit the testing of a spark plug irrespective of the variations and threads on the plug.
' A further object of the invention is to provide a simple and reliable spark plug tester.
There are in common use in this country a great number of makes of spark plugs and unfortunately the threads on the spark plugs have not yet been standardized, there being three largely used sizes of threads and this requires three different spark plug testers of the usual type one for each of the three styles of plugs. In the structure shown in the drawings a single housing is provided and a rotatable disk is mounted on the housing so as to bring any one of three'tapped openings into registry with the pressure chamber so that any spark plug may be tested with. ease.
In the drawings, y
Figure 1 is a front elevation of a spark plug tester made in accordance with my invention.
Fig. 2 is a central vertical section.
The main casting or housing consists of a substantially circular plate 10 having an integral base 12 formed therewith by means of a stiffening rib 14. A cylindrical pressure chamber 15 extends forwardly from the plate lO and like the rib and base is an integral part of the housing or`casting. 'Ihe front side of the pressure chamber 14 is closed by a disk of glass 17 held in place between two steel washers 18 by means of a hollow threaded plug 19 having a square end 20 for convenient insertion and removal of the plug. The rear face of the casting or housing is machined and receives a similarly machined face of a rotatable holder 22 pivoted to the housing by means of a bolt 25. The holder 22 is provided with three equally spaced openings 26, 27 and 28 each tapped Aopenin to receive a spark plug of one of the three standard types and by rotation of the spark plug holder 22 and one of the three holes may be brought into registry with the axis of the pressure chamber. I find it convenient to engrave a mark on the periphery of the disk-like holder 22 in line with each of the three openings and to then engrave a similar mark on the housing in or to facilitate the exact registry of the desired opening with the pressure chamber. When the 26, 27 or 28 with its spark plug 29 in p ace and ready to be tested is brought into registry with the pressure chamber the bolt 25 is tightened at which time the presstandard gage 31 in the line between the tester and a pump not shown.
The spark plug 29 is connected through f sure chamber is closed except for its com- -mun1cation through the pipe 30 with a a battery 32 with the metal of the housing providing the customary high tension spark between the electrodes of the plug.. Fluid under pressure is conveyed to the pressure chamber by means of pipe 36 and if desired the pressure in the chamber may be brought to the highest pressure shown on the dial of the gage 31 and the valve 37 closed when such pressure is reached. The supply of current to the spark plug is now closed by means of switch 39 and the air allowed to leak slowly from the chamber by a slight opening of the valve 37 so by watchlng through the peep hole in the stud 2O and at the same time by observing the dial of the y gage-37 it is possible to determine the exact said chamber, characterized by the spark.
plug holding means being rotatable and having a plurality of spark plug holding openings therein.
2. A spark plug tester of the type havin a pressure chamber, a gage connected wit said chamber, means for conveying fluid under pressure to said chamber, and means for holding a spark plug in registry with said chamber, characterlzed by the spark Aplug holding means being rotatable and having a plurality of spark plug holding openings therein, said openings being of dii'- ferent diameters.
3. A spark plug tester of the type having a pressure chamber, a gage connected with said chamber, means for conveying fluid under pressure to said chamber, and means for 'holding a spa-rk plug in registry with said chamber, characterized by the spark plug holding means being rotatable and havn ing a plurality of spark plug holding openings therein, the spark plug holding means comprising a disk provided with a plurality of openings adapted to be successively brought into registry with said chamber, said disk being pivoted to the chamber housing to one side ofthe axis of said chamber, said disk and said housing having machined cooperating surfaces.
4. In a spark plug tester, a support havinga cylindrical chamber therein of substantially the same diameter as a spark plug, a transparent closure for said chamber, a hollow plug for holding said closure in place, means for holding a spark plug coaxial with said chamber and said hollow plug, and means for conveying fluid under pressure to said Chamber, said holding means being rotatable about an axis parallel to the axis of said chamber and hollow plug.
5. The device of claim 4- in which the spark plug holder has a plurality of threaded openings therein of different diameters.
