DRILL Filed March 15, 1928 awe/11 6010 I Silbezggez Patented Get. 14, 1930 PATENT OFFICE JULIUEl SILBERGER, OF CLEVELAND, OHIO DRILL Application filed March 15, 1928. Serial No. 261,772.
' This invention comprehends the use of air in digging or drilling mechanism for the purpose of conveying the dug material, which is in a partially comminuted state, the last named condition being caused partly by the drilling apparatus itself, and partly by the action of the air on the loosened ground.
In carrying out my invention in actual practice, I avail of a casing that is hollow throughout and has allixed atone end thereto appropriate digging instrumentalities, which are primarily designed to cut earth, either hard or otherwise, and pass the loosened earth back into the casing. Extending throughout the casing is a tube of comparatively small diameter as compared with the bore of the casing, which functions as a conduit for a pressure fluid, such as compressed air. Openings in the tube aforesaid, adjacent to the digging instrumentalities, permit the fluid to intermingle with the dug material and, under pressure, force the same back up and out of the casing in the space between the walls thereof and the walls of the tube.
A particularly noteworthy feature of novelty resides in the construction of the casing at the digging end. In a preferred form I have notched the end of the casing to provide what are in effect radial cutting edges thereon, which, upon operative rotation of the casing, function as part of the digging instrumentalities. Other such memhere are radial knife blades enclosed by the walls of the casing at the notched portion thereof, and a screw member which is adapted to taking a holding in the earth or sub stance upon which the mechanism is intended to operate.
Another praiseworthy feature of a drill provided by my invention is its adaptability for operations upon soils of widely varying character. The screw member aforesaid, is capable of diggin in and obtaining a footing in even the hardest shales, and the d instrumentalities are particularly desi i ml to effectively operate under such. unfavorable conditions. I
A more detailed feature of novelty lies in the arrangement of the holes provided in the fluid tube interiorly of the casing. These ing of my novel idea, reference may be had to the following description and accompanymg drawings in which,
Figure 1 13 a view 1n side elevation of the working end of a drill made in accordance with this invention.
Figure 2 is a longitudinal section through the drill taken about on the line 22 of Figure 1.
Figure 3 is a plan view from the bottom, bringing out particularly the arrangement of the digging and cutting instrumentalities.
Figure 4 is a showing in perspectiveof a position of the digging means, and
Figure 5 is a detailed view in perspective of one of the radial cutting blades.
While a preferred specific embodiment of the invention is herein set forth, it is to be understood that I am not to be limited to the exactconstructions illustrated and described, because various modifications of these details may be provided in putting the invention. into practice within the purview of the appended claims. I
, The working end of a drilling or digging mechanism provided by this invention, is
shown in Figures 1 and 2, and comprises a hollow, cylindrical casing A, having a bore extending throughout its length. Arranged preferably coaxial with the casing A, and interiorly thereof is a tube B, which has its extremity made fast to a portion of the digging instrumentalities indicated generally by the reference character C. These instrumentalities preferably include a stud l, which plugs up the end of tube B, and is affixed thereto in any approved manner, such as by a screw threaded connection as'shown at 2.
The tube B maybe held properly spaced with respectto the walls of the casing A, by
may be affixed thereto in any appropriate manner, and which also have 'PIOJG-Cti'OHS 8, that find suitable bearing in the walls of the casing A, asindicated at 9.
Referringfn'ow more particularly to Figure 1 it is noted that the extremity of the casing A is notched, or serrated, as shown at 10, to provide cutting edges 11 that are radial in character. These cutting edges are adapted upon proper rotation of the casing 10, to 0p erate on the substance on which the drill is working, to cut and loosen the same. Needless to say, the cutting edges 11, the
2. Drilling apparatus of the class described comprising a casing, a fluid pressure tube axially disposed therein and having rearwardly inclined passages in the walls thereof adjacent to the forward end, digging instrumentalities positioned at the forward end of said casing, said digginginstrumentalities comprising a stud removably carried by the "end of said fluid pressure tube, a tapered feed screw formed on said stud and projecting beyond the casing, and radial cutting blades at the base of said feed screw, said blades constituting spacing means for the end of the fluid pressure tube and means forpositively interlocking the said digging instrumentalities to prevent shifting of the latter with respect to the casing and fluid pressure tube incident to operation of the same to remove material in advance of the sa1dd1gging instrumentalities whereby to cause the said material to be sub ected to the action of the fluid pressure to ,comminute the same and convey it rearwardly between the casing and 1,;

ward so that any fiuid passing therethrough will have assumed a partial returning direction. The tube B is adapted to have fluid under pressure, preferably compressed air,
passed therethrough andout through openings 12 into the space between tube B and easing A.
UponproperdriVin'g action being imparted to the casing A, the digging instrumentalities 0 function to cut and loosen material, which is passed back into the casing A, where it has mingled with it the compressed air coming from the openings 12, which causes the material to assume a comminuted condition'in which it is passed -u through the casing A, exterior of the tube and delivered to any desired point. I
Having thus described my invention, what I claimas new, and desire to secure by Letters Patent of the United States is 1'. Drilling apparatus of the class described,
comprising an outer casing, a fluid pressure tube-axially disposediwithin' said casing, said tube having a pluralityiofrearwardlyinclined passages ad acent to the forward end thereof, drilling instrumentalities carried by V the end of said tube constituting a closure for said end, said drilling instrumentalities having a longitudinal passage therein and lateral passages extending from said longitudinal passage in register with certain of the passages in the tube, said drilling instrumental ities constituting means for spacingthe end 7 of the tube from the casing, and locking
