1 Claim. l
The present invention relates to new and useful improvements in tools for removing broken spark plugs from engine cylinders.
An important object of the invention is to provide a tool of this character whereby a broken spark plug may be removed without damage to the spark plug opening and without danger of fragments falling into the engine cylinder.
A further object is to provide a tool of this character of simple and practical construction, which is efficient and reliable'in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a perspective view of the broken spark plug extractor;`
Figure 2 is a perspective View of the jig for use with a drill in drilling the spark plug opening to receive the extractor;
Figure 3 is a perspective View of the removable handle for the jig;
Figure 4 is a perspective view of the stopper for sealing the bore of the broken spark plug;
Figure 5 is a top plan view of the jig;
Figure 6 is an enlarged vertical sectional view showing the jig in position in the broken spark plug;
Figure 7 is a similar View showing the extractor in position for removing the broken spark plug; and
Figur` 8 is a transverse sectional View taken on a line 8-8 of Figure '7.
Referring now to the drawing in detail, wherein for the purpose of illustration We have disclosed a preferred embodiment of our invention, the numeral 5 designates a jig having a round ilat head 6 and a shank 'I extending downwardly at the underside of the head. Head 6 is formed with three vertical bores 8 in a central triangular arrangement and each in the vertical plane of one side of shank 'l to provide vertical grooves 8 in the sides of the shank and which terminate inwardly from the lower end of the shank. The top of head 6 is also formed with an eccentric tapped opening l0.
The shank 1 olf the jig is adapted for placing in the bore II of the threaded inner end I2 of a broken spark plug with the head 6 resting on top thereof, as shown in Figure 6, and a drill I3 is then successively placed in the bores 8 to expose the side of the drill in the grooves 9 for drilling internal grooves I4 in the bore II of the broken spark plug. A stopper I5 is placed in the bottom of the bore II of the broken spark plug and grease packed therein to seal the lower end of the broken plug and prevent particles of metal falling into the cylinder of the engine during removal of the broken plug.
A handle I6 is threaded in eccentric tapped opening I0 to hold the jig stationary while drilling the internal grooves in the broken plug.
An extractor, designated at I1, is constructed to provide a central hand gripping body I8 with a squared wrench engaging upper end I9 and a substantially triangular shaped stem 20 at its lower end. The corners 2l of stem 20 are formed with longitudinal teeth 22 projecting uniformly from each angular surface 23 of the stem 20.
After the internal grooves I4 have been drilled in the bore Il of the broken spark plug, the jig 5 is removed and the stem 20 of extractor I'l is then inserted in the bore II and with the teeth 22 positioned in the grooves I4, as shown in Figure 8. A wrench (not shown) is then applied to square upper end I9 of the extractor to turn the same in a direction to back the broken spark plug out of its opening.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.
It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.
Having described the invention, what is claimed as new is:
A broken spark plug removing tool comprising a drill jig having a head portion and a stem portion, the latter adapted to enter the bore of a broken spark plug while the head rests on top thereof, said head having a triangularly arranged group of drill guide openings and said stem having longitudinal drill guide grooves alined with the openings of the head to expose one side of a drill entering the openings for cutting internal grooves in the bore of the broken spark plug, said grooves being closed at their lower ends to exclude drill particles from dropping through the bore of the broken spark plug.
