SPARK-PLUG CLEANER.
' Specification of Letters Patent.
Application filed August 11, 1919. Serial No. 316,661.
T oil whom it may concern," 7
lie 1t known that I, lVAn'rnn la. BOARD- MAN, a citizen of the United States, a.resident of Decatur. in the county of Macon and 'State of Illinois, have invented new and useful Improvements in Spark-Plug Cleaners, of which the following is a specification. I
This invention relates to certain newv and useful improvements in a spark plug cleaner, and especially to a cleaning tool adapted more particularly for the cleansing of the A@ type'of plug which necessi- Patented July 27', 1920.
and 5. In the instance at 4;, ,tlieend 7 is 1 shown as being used as a gage, or also used n separating the points preparatory to filmg the end of the right-angled terminal, the latter filing being depicted in the instance as shown at 5. The instance 5 also shows the blade used as a gage to determine proper spacing of the parts. After filing, the points are moved together and then the blade is inserted between the same as depicted in full anddot-ted lines inl ig, l to determine proper spacin One side faceof the gage, preferably the face opposite tate's the use of four tools, namely, a screw to. the convex face of the scraping blade 1,
driver, scraper, file. and gage.
The principal object of the invention is to provide an improved single tool capable of performing these combined functions in an ellicient and facile manner. 1
A further object resides in the provision of a light combination and integral tool having an intermediate handle or grip portion, a scraping blade on one terminal and a file on the other of a predetermined thickness to constitute a gage for facilitating the proper setting of the sparking points or terminals of the plum' Further, the invention resides in the to tures of construction hereinafter described and claimed, reference being bad to the accompanying drawing, wherein,
Figure l is a perspective view of the combination spark-plug cleaning tool;
Fig. 2 is a similar view of the tool depicting the opposite or file side thereof;
Fig. 3 is a transverse section on line 3-3 of Fig. 1, through the lile and gage part of the tool; and
Fig. 4% is a side elevation of the trating it functioning as a gage.
The tool comprises a steel bar reduced at one end to provide a tapering bladel having one side face 2 convexcd substantially to the inside curvature of the spark plug and both longitudinal cdgcs sharpened for scraping thecarbon deposit from the inner wall of the plu The opposite end of the bar or body is flattened to a thickness equal to the space betweentwo properly set points of the plug whereby to serve as a gage 3 for setting the points subsequent toclcaning the same, as indicated in the two instances shown at a tool, illusis formed into a file 6 by which the plug points may be abraded and more easily cleaned. The extreme end of the file and gage part terminates in screw-driver 7, useful in cleaning plugs of the well known i\.-C type. Thehandle 8 is formed. between the scraper and gage parts by reducing the bar of steel from one side only whereby the handle will project therefrom and'leave the opposite side, which is provided with the filing surface, fiat. The single hand thus serves while functioning with either end of the tool. It will be noticed that during the process of filing the points, the gage may simultaneously be brought into'play so that the points may be pressed together or otherwise set in properly spaced relation The single tool embodies all the tool parts essential.fonclcaning a plug, each part acting to facilitate the operation of another part so that a plug may be expeditiously cleaned in an ellicicnt manner.
What I claim is:
l. A combined sparlcplug point cleaner and gage composed of a member having a blade formed with a smooth face on one side and having the tace of its opposite side provided with tile teeth so that the smooth face can engage and slide on the straight point of the spark plug while the file teeth are acting upon or cutting the end of the usual right-angled point of the spark plug, and said blade being of such thickness as to act as a gage to determine proper spacing lio points, the free end of the blade being smooth on both faces so as to allow it to be used to wedge the points apart in initially introducing the blade between the points.
especially v,2. A spark-p1ug cleaning-tool colhprisihg ti blade having a predetermined thickness" equal to'the p 'oper spacing of the points of the plug, whereby the same'may function as 5 'a gege'to' set the points during the'filing thereof, said blade having file teeth on one face and its opposite face smooth so that it may engage 'endslid'e on the straight point of the spark plug w hile the file teeth are 'ecting upon or cutting the end of the usual 10 ri ht-angled point of the spark plug.
I niwitness whereof, Ifhave hereunto at fixed my hand this 31st day of July, 1919.
V WALTER L. BOARDMAN.
