HARRY DALITZ, OF SEATTLE, WASHINGTON.
SPARK-PLUG TESTER AND TERMINAL.
To all whom it may concern Be it known that I, HARRY DALITZ, a citizen of the United States of America, and a' resident ,of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Spark-Plug Testers and Terminals, of which the following is a specification. I
My invention hasfor a primary object to provide a device of simple construction through the medium of which the electrical current can be caused to pass from the side pf the working circuit to the other side thereof without passing between the electrodes of the spark plug. A further object resides in the provision of a device of this type which is durable, comparatively inexpensive to manufacture, and further, capable of adjustment whereby it can be adjusted to either close or open the short circuit.
Further the invention aims to provide a-- structure wherein such short circuiting connection is comblned wlth a terminal memher for the electrode conducting wire of thespark plug. 1
Other objects will be set forth as my description progresses and those features of construction, arrangements and combinations of parts on which I desire protection, succinctly defined in my annexed claimsQ Referring to the accompanying drawing,
wherein like numerals of reference indicate like parts throughout: Figure lis an elevation of a spark plug" provided with my invention, the hand hold or handle member being shownin section. Fig. 2.is "a perspec-.
tive of the terminal member, and Fig. 3 is a perspective of the short circuit closing member.
Referring to the drawing by numeralsof reference, 1 indicates a terminal member adapted to be connected to wire 2 of one side of the working circuit, as by pliable edge extensions 3, which latter are bent over the circuit wire and then, if desired, soldered or otherwise held in fixed relation. Memher 1 which comprises a flat metallic plate, is conveniently notched, as at 4, for reception of the outer externally screw-threaded end portion of plug 6. This conducting wire is provided with the usual 'champing nut 7 and electrode 8, the latter cooperating with an elec ings l0 and this,

make contact with' the outer shell of thespark plug. A spring lea'f 13 is fixed for movement with member 11'- through openthrough its tendency to spring from the conducting member "is frictionally held in its adjusted position.
Spring leaf 13 can, if desired, be formed integral with conducting member 11 and desirably has its free end portion turned out wardly to provide a upward movement. The upper end portion of member llis provided with a .hand hold or handle 15, of insulating material, the same being provided with an annular guard flange 16 and preferably having screw-threaded engagement with the conducting member shank extension 18. In my present construction, I have shown the lower aperture 10 provided in the tion 1 of terminal member 1.
In practice, the conducting member 11 will normally. be elevated, as shown in Fig. 1. From this position it can belowered, being slid through openings 10, to test the strength of the current, it, at such time, being adjusted to vary the'spacing of its end portion .12 with respect to shell of plug 6, as will be readily understood. For detecting a foul for the tip portions of the fingers stop 14 for limiting its turned under end porplug or one which is notsparking properly n an engine having two or more cylinders, the operation would be as follows: The several spark plugs of the cylinders are allowed to each, in turn, be connected in the'working circuit while the remaining spark plugs are short circuited through the closing of their conducting switch members. Thus, each spark plug can be individually tested as to its proper operation without-removing the samefrom the cylinder.
' Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United of Amertion.
wardly ica, is
a plate adapted to be mounted, on a spark plug and having an extension projecting beyond the latter, said extension having a seat formed therein, and a conducting member slidably engaged in the seat of the terminal member and being of curved formation whereby on sliding the conducting member the contacting portion thereof will move into engage the plug.
2. A device of the. character described comprising a terminal member consisting of a plate having an extension formed with a seat; a conducting member slidably engaged in the seat of said terminal member for short circuiting the'spark plug, and a resilient element integral with said conducting member for holding the same in its adjusted posi- 3. A device of the character described comprising a terminal member consisting of a. plate having an extension formed with a seat, a conducting member slidably engaged in the seat of said terminal member for short circuiting the spark plug, and a resilient element carried by said conducting member for holding the same in its adjusted position.
I: 4; device of described a I Y r comprising a terminal member having one -1. A device of the character described comprising a terminal member consisting of:
end portion turned back and provided therein together with said end ortion with alining apertures, and a cond oting member for short vcircuiting the spark plug;;said,.;conducting member being slidably engaged in the apertures of the terminal member and curved inwardly to engage the spark plug on sliding said conducting member. y
5 A device of the characte described comprising a terminal member having one end portion turned back and provided therein together ing apertures, a conducting member for short circuiting the spark plug; said conducting member being slidablyrengaged in the apertures of the terminal member and curved inwardly to engage the spark plug on said conducting member, and a resliding silient element carried by said conducting member and engaging in the apertures of the terminal member for holding the conducting member in adjusted positions.
