' COMBINED DRILL AND HOLE CLEANER.
Application filed July 13,
This invention relates to new and useful improvements in a combined drill and hole cleaner.
It is the principal object of our invention to provide for ldrilling rock, brick, cement, concrete and other hard or semi-hard material, a simple compact and 4efficient drill which cleans the hole as it drills it. t also eliminates the friction caused by dust collections, and drills a straighter and truer hole.
Other important and incidental objects will y be brought out in the following specification and particularly set forth in the subjoined claim.
In the accompanying drawings illustrating our invention, Figure 1 is a longitudinal sectional view taken through our drill. Figure 2 is a cross-sectional viewy taken through the drill on the line 2 2 of Figure 1. And Figure 3 is a view looking toward the fluted end of the drill. 'f
' In the accompanying drawings illustrating y our invention, the numeral 1 designates a barrel which is constructed of case-hardened nickel, steel or other suitable material. The upper end of this barrel is internally threaded to receive a.. flanged plunger collar 2 constructed of cold rolled steel or other suitable metal.
F rce to move in the bore 3 of the barrel 1 is a plunger 4 that is formed at its middle portion with an annular shoulder 5. To ease the shock of impact! of 'the shoulder 5 with the collar 2, the latter is protected by a leather washer' 6 which is placed in the barrel 1 imme diately below it. Formed in the barrel 1 below the washer 6 are air inlet holes 7.
The shoulder 5 on the plunger 4 is normally held against the washer 6 by a coil spring 8 that surrounds the plunger between said shoulder and a tool steel tempered disc 9 mounted at the bottom of the bore 3. This disc also receives the shock of the plunger when its upper end is subjected to a hammer blow. s
Formed in the disc 9 is an aXial air hole 1() which communicates with an air hole 11 that leads downwardly vthrough the solid lower end of the barrel` to the tapered seat 12 lof a ball valve 13. This seat 12 forms the upper end of a bore 14 in the reduced low-er end 15 of the barrel 1.
Firmly secured within the lower end 15 of 1927. serial No. 205,361.
the barrel by a set screw 16 is the upperend of a drill 17. Formed on the-upper part of y i this drill is a shock shoulder 18, and extending from the top ofthe drill through itslower the. drill point 19 to forcibly engage said ma'- terial. Under the impact of the blow, the
The ball valve 13, which has been forced below its seat kby the air pressure created by the descending plunger, will bereturned to its seat by the spring 21upon the elevation of the plunger by the spring 8, to prevent back suction of dust and dirt into the barrel k1.
Our drill may be operatedl by the hand,
compressed air, steam or electricity to drill Va hole in a hard or semi-hard material and clean the holewhile it is beingdrilled.
We do not wish to be limited to the details f of construction and arrangement herein shown and described, and any changes or modifications may be made therein within the scope ofthe Subj oined claim. Y
Having described our invention, we claim cating axial holefa plunger in said barrel, a'- ball valve in said bore to close the hole in the,
lower end of the barrel, and a coil spring inl terposed between the ball and the `top of the drill point for the purpose specified.
InA testimony whereofwe have hereunto set our hands this 11th day of` uly, 1927.
