HEAD. FOR BORING-BITS.
' To all whom it may concern:
Be it known that we, WILLIAM GALE PARRY and PATRICK J OSEPH OREEDoN, both of Peterborough, county of Peterborough, Province of Ontario, Canada, have invented certain new and useful Improvements in Heads for Boring-Bits, of which the following is a specification.
Our invention relates to improvements in heads for boring bits, and the objects of our invention are to provide an exceedingly cheap and simple form of head which may be removably connected to the shank of the auger which will be of cheap manufacture and in which the cuttings will not congest; and it consists essentially of a tubular shell or hollow head removably attached tothe shank having at the bottom two inwardly extending projections adapted to form the cutting edges and. having apertures in the sides and means for diverting the cuttings outwardly through the apertures, all as hereinafter more fully set forth and described in the accompanying specifications and drawmgs.
In the drawings, Figure 1 is a side view partially in section. Fig. 2 is a side view similar to Fig. 1, partially in section, and with the bit turned through an angle of ninety degrees. Fig. 3 is the same view as Fig. 2, only not in section. Fig. 4 is an end view. Fig. 5 is a side view partially in section'of an alternative form of the invention.
Fig. 6 is a plan of the blank from which the head shown in the previous figures is formed. Fig. 7 is a side view of an alternative form of head. Fig. 8 is a longitudinal section through the same.
In the drawings, like letters of reference indicate corresponding parts in each figure. Referring to the form illustrated in Figs. 1 to 4, a is the shank of any desired form. I) is the head, tubular in form, and detachably connected to the shank by any suitable means, the means we show to accomplish this comprising a set screw 0 extending through the shank and through a constricted portion d in the tubular head.
The bottom of the head is formed with two inwardly extending projections e and f having the edges g and h thereof adapted to serve as cutting edges. Between the projections e and f a spiral screw '1', is secured, either riveted in position or soldered electrically or otherwise secured solidly in posi- Specification of Letters Patent.

tion. The projecting spurs j and 7c are, as usual, formed from the bottom.
The tubular shell or hollow head I) has formed at the side thereof openings Z and m, and on the interior of the head are formed inclined grooves 'n and 0 adapted to guide the cuttings out through the a ertures. Ordinarily the cuttings from the it would pass up the center of the tubular head and clog therein, but the inclined grooves being formed on the inner walls cause part of the cuttings to be engaged thereby, and divert it from the openings. This carries the remaining cuttings, and clears the interior of the head.
In manufacturing the head, it is first stamped out of thin sheet metal into the form shown in Fig. 6 and is then bent to a proper form through a die in a wellknown manner.
In the alternative form shown in Fig. 5, the shank a is extended through the tubular head and has the spiral screw 4) formed integral with the end thereof.
In the alternative form shown in Figs. 7 and 8, the openings Z and m are made spiral in form, thus serving to readily clear the head of the cuttings and avoid the necessity of the formation of the guiding grooves n and 0. This form of head will not be stamped from a blank but will be drop-forged in a wellknown manner. Where desired, the spiral commenced by the openings Z and m may be continued by a suitable groove formed in the shank.
As the heads may be very quickly detached, the one shank will serve for a great number of heads, thus effecting a large saving of material and economizing room in the packing of the heads and shanks. Also, if desired, different lengths of shanks may be used with the same head, according to the class of work being carried out, and different sizes of heads may be used with the same shank. v
The cuttings of the bit while in operation cannot congest in the head as it does in the ordinary bit between the periphery of the bit and the hole being bored, for in this bit the cuttings pass upward through the tubular head and are guided outwardly-by the inclined grooves or the spirally formed apertures.
This head is of an exceedingly cheap and simple construction and may be manufacturedfor about one-quarter of the cost of the ordinary head.
While the invention has been described herein with great particularity of detail, yet it will be readily understood that in carrying out the construction of the same, changes might be made in the detail, without departing from the spirit of the invention.
What we claim as our invention is z 1. An improved boring bit comprising a solid shank, a hollow tubular shell having an upper portion reduced. in diameter and secured to the shank, having two projections at'the bottom bent inwardly and formed with substantially horizontal cutting edges, and also having openings in the sides through which the cutting may pass, and transversely inclined grooves formed on the inside of the tubular shell adapted to guide the cuttings through the openings.
2. An improved boring bit, comprising a solid shank a hollow tubular shell having an upper portion reduced in diameter and secured to the shank, having two projections at the bottom bent inwardly and formed with substantially horizontal cutting edges and also having openings in the sides through which the cuttings may pass, and vertically extending cutting spurs formed on the sides of the tubular head.
3. An improved boring bit comprising a solid shank having a spiral screw formed on the extremity thereof, a hollow tubular shell through which the shank extends, having an upper portion reduced in diameter and secured to the shank, and having openings in the said shell through which the cuttings may pass, and also having two projections bent inwardly at the bottom and formed with substantially horizontal cutting edges.
