EUGENE H. SLAGLE, OF ENNTS,- TEXAS.

Application filed September T all whom it mag concern v Be it known that I, EUGENE H. SLAGLE, a.
I citizen of the United States, residing at Ennis, in the county of Ellis and State .of' Texas, have invented certain new and useful Improvements in Carbon-Removing Tools.
of which the following is a specification.
This invention relates. to new and useful improvements in carbon removing tools.
The purpose of theinvention is to'pro- ,vide means for removing the'carbon' from the ring groovesof the pistons of internal combustion engines, and particularly for cleaning grooves of different widths.
In carrying out the invention a yokeshaped member is provided at one end with a guide arm or jaw adapted' to receive one side of a. piston. On the other end of the member, a laterally directed scraper is arranged diametrically opposite the v1 aw so as to stand at right angles to the piston and engage in the groove's'thereof. The member her arcuately I the scraper is made of resilient metal so as to cause the jaw and scraper tosnugly embrace the piston. The scraper is arranged to present different widths of blades to fit different widths of grooves. By swinging the mem- The member may have a. compressgroove.
for pressing the piston rlngs 1nto ing loop the grooves.
The invention willbe more readily under stood from a. reading o-fthe following specificati-on and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein: I
Figure 1 is a plan view of a tool constructed in accordance with my invention and showing its normal configuration in dotted lines,
Fig. 2 is aside elevation of the same,
Fig. 3 is a. front elevation of the scraper,
, Fig. 4 is a cross sectional detail on the line H of Fig. and. p Fig. 5 is a plan view of the tool in position on a piston for pressing the ringinto the groove. Y
In the drawings the numeral 10 desig nates a general yoke-shaped member preferably formed .of a single piece of spring metal of the flat bar type. The member constitutes a. handle-for manipulating the tool. At one end the member is forme'djinto an arcual loop 11, which also constitutes a hinge. One of the ends of the member is tw'i bed at right angles and bent angularly blade cleans the ear-1920. semi u 413,274..
to form a V-shaped jaw 12. The outer end I '13 of the 'jaw is rounded so as not tocatc'h on the piston. 4 r
The 0th rend or arm of the member terminate's short ofthe end of the jaw and has an outwardly directed car 1 1 bent at substantially right angles'to the arm ofthe member. On the outer side of the car .a rectangular scraper 15 is centrally pivoted on a rivet 16.. A spring washer 17 interposed between the head of the rivet and the scraper, holds the latter in frictional engagement with the ear, thus tending to main-- tain the scraper in the position to which it is rotated. I The scraper is positioned substantially diametrically opposite the crotch of the jaw 12. Radial scraper blades- 18 extend from the edges of the scraper and are angular with their outer and side edges at substan- "tially right angles to each other. These blaales are each preferably of a difierent width, each having substantially the same width as the width of theparticular groove to -be cleaned thereby. For instance one blade is wide enough to fit a, piston ring I one of the other blades has a width designed to fit a. groove one-quarter of an inch wide.
It is to be understood that the number of blades may-vary and if desired two could be made of the same width.
In'using the tool the scraper 15 is rotated to bring the proper blade 18 opposite the crotch of the jaw '12. The jaw' is sprung away from the scraper so as to grasp the piston A ,in its ring groove B, in full and dotted lines in Fig. 1. This causes the blade 18 to firmly engage in the groove: B. It is pointed out that the V shaped jaw is always self centering, irrespective of the diameter of the piston. After the tool is in position the carbon is removed by swingingthe member around the piston, whereby the blade 18 standing radially, cuts the carbon by means of its angular edges. holds. the scraper blade in the groove and thea work is-quickly i done and a clean job When the groove has been cleaned the tool is removed. and; the piston ring O is slipped over the piste to'the groove. It is often necessary to press; the ring into the The resilient jaw yieldably,
