Description

y 1945- R. M. RINGLER 4 2,380,330
DRILL BIT SUPPORT Filed Oct. 12, 1943 Patented July 10, 1945 UNITED STATES PATENT OFFICE DRILL BIT SUPPORT T Rudolph M. Ringler, Wymore, Nebr. Application October 12, 1943, Serial No. 505,993 1 Claim (01. 279-42) My invention relates to small drill bits, and
has among its objects and advantages the 'provil sion of an improved drill bit support to reinforce the bit against bending when pressure is applied thereto.
In the accompanying drawing: Figure 1 is a view of ya conventional bit and my support.
Figure 2 is an enlarged sectional view of the support, and, a
Figure 3 is an enlarged sectional view on the line 33 of Figure 1.
In the embodiment of the invention selected for illustration, I make use of a conventional drill bit I and. the usual brace chuck l2. Bits 01 small diameters frequently bend because of presa stiffening support for the drillbit throughout sure applied thereto during the drilling operation. To resist such bending I make use of a support l4 made up of sections l6,which sections have longitudinal grooves l8 therein to receive the drill bit l0. 'Both grooves l8 extend the full length cftheir respective sections l6; To afford effective support for bits of different diameters, v
the support is made up in different sizes, particularly with respect to the grooves l8 so that the These sections are of such length as to be receivable in the chuck [2, so that the sections iii are clamped firmly to the drill bit throughout the greater extent of their lengths. With the drill bit [0 clamped accordingly to Figure 2, the bit is reinforced so as to resist bending. The sleeve 22 is tightened upon the section I6 before the sections. are inserted in the chuck,
and the drill bit may be projected from the sections IE only sufliciently far to accommodate the thickness of the work being drilled, which afiords its greatest possible length.
Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
I claim: I
A stiffening device for use with drill bits of small diameter in holding the same in drill chucks, comprising a pair of cooperating elongated grooved sections adapted to receive the drill bit in the grooved portion therebetween, and of a length to extend beyond that portion of the bit engaged by the chuck to fully receive the clamping jaws of the chuck, the outer ends of said sections being tapered and threaded and ,en-' gaging the bit to a point adjacent the efiective drilling portion of the bit, and an internally threaded tapered sleeve engaging the tapered ends of the tapered sections to clamp the sections together on the bit.
