' My 'nvention .relates to ldrills used d rill- .f ing Artesian and oil wells. In this class of ro ldrilling the bestresults havev been found to be attained by using what is known as a lshtail bit, called'that because of itsresem- 1 blancs to a'shtail These bits, which are made in'one ieee, are'quite expensive, and 15 as .the bit-blades soon wear out, Anecessitating throwingaway thewhole bit', theiruse is a large item inthe cost offsinking al well. lIn
my invention, described hereinafter, the bitblades arejseparablejiromthe,dr1'l lhead,'so z 0- th'at Wherio'ne set. cibladesbecome worn f out through use they may be removed from :the drill-head and-a 'new set of blades inserted in theirste'ad.` l-As in use the shanks of these blades by abrasion on the slots in the 25 'head containing them wear'down, so that they would becomeloose in the head, my in- -vention also contemplates the inclusion of means" for automatically ytightening the blades inthe head, which means consists of a '30'screw-plug.inserted in the head and havin' its lower end bearing against the Shanks `o the,bitblades, so asto prevent them from becoming loose in the 'drill-head, the screwplu being constructed 1n relation to the 3 5 dril -rod s o that the twisting motion of the drill-rod in operation turns the plug to automaticall tighten the Shanks oflthedrill-bits @should rey become vloosened in operation, thus dispensing with the necessity of removofing the drill rod and head'from the well and dismembering the drill to manually tighten .the bit-Shanks.I l My invention will bedescribed in detail hereinafter and illustrated in the accompany- 45 ing drawings, inwhich` Figure 1 is a view showing the drill-head, a
Ifragment of the tubular drill-rod, and' the coupling in section, and the bit-blades and securing-plug 1n elevation; t Fig. 2, a cross-sec-- 5o tion on 'the linea: ne of Fig. 1 ;'.Fig. 3, a view in elevation of the drill-bit, and Fig. 4 -a top plan view of the plug. j

a threaded coupling-ring to t the `screw- 1 represents my improved drill-head having a bore 2 therethrough with its upper-end screw-threaded, as shown at 3, and in the lower ortion of the head are slots 4, which exten radially from the bore 2. Each slot 2 6o `is formed wider at the top 5v than at thebottem 6, so as 'to receive the shank? vof drill-bit ,8,which1s'formed wider at its top 9v thanat the point 1 0 adjacent to the bit.

The lower end of plug 11 is tapered 'or'coneshaped,as shown` at 14, to fit the inner edges 15 or' the drill-bit shanks 7, 4whiletheupper end of the plugls .formed with a wide iat head r16, having serrations17 18 represents a borethroughthe 4plugto admit ofl the flow of waterto the drillbits 7 5 when desired.

drill-rod 19, respectively.
I n' use when my drill` is assembled. as
shown in Fig. 1,-..the` twisting of the drill-rod 19 while in operation has. the'v tendency to 9o keep the plug 11 driven downinto the head 1 as far as possible, which keeps the bits rigidly secured in the drill-head at all times. Having thus described my invention, what Iclaimis- 95 1. In a drill, a drill-head, having a threaded bore therethrough, a drill-rod rotatably,
secured to said drill-head;V drill-bits mounted in said drill-head, a threaded plug secured in the bore in the drill-head, and operative conroo nections between the plug and drill-rod, substantially as shown and described.
2. In a rotary drin, a drin-head having@ f threaded bore therethrough, a drill-rod ro'tamounted in the threaded bore in the vdrillhead and engaging said bits to hold them in the drill-head, the top of said plug and the lower .end of the drill-rod serrated so that the 1 1o plug is driven into the drill-head during and described. A
3. In a. drill, a drill-head having ,ai screwtlireaded bore therethrough. and radial slots extending from said bore into the drill-head,
drill-bits mounted in said slots, a screwthreaded plug mounted in said bore-and engaging said bits to hold them in position, av
drill-rod revolubly mounted in saiddrillread, and operative connections between .said plug and drill-rod to rotate the plug 1n the. bore in the drill-head, substantially as A shown and described.
4; Ina drill', a drill-head having a`serewthreaded bore therethrough and radial slots extending from said bore into the drill-head,
drill-bits, the shanks. of said bits mounted in vsaid slots and having their inner edges slant- 'ing and extending into said bore, a screwplug to lit in the bore-in the drill-head and having a tapered end ltoengagethe inner edges of the bit-Shanks, a drill-rod revolubly 'tions, and a drill-rod revolubly mounted in said drill-head having serrations on its lower 'endI toit the serrations on the top of thel plug, substantially as shown and described.
6. In a drill, a'drill-head having a screwthreaded bore therethrough and radial slots extending from said -bore into the drill-heady. drill-bits, the Shanks of said bits mounted in 'said slots and having their inner edges slant- 'ing and extending into said bore, a' screwplug to t "infthe'bore in the .drill-'head and eases?,
plug provided with sei-rations, and a drillrod revolubly mounted in said drill-head having serrations on its lower end to iit the serrations on the top4 of the plug, substantially as shownand described.
7. In a' drill, a drill-head having a screwthreaded bore therethrough and radial slots extending from said bore into the drill-head,
drill-bits mounted inv said slots, a screwthreaded plug mounted in said bore and engagiit g said bits to hold them in position, the upper end of said plug provided with a Wide flat head-having a serrated surface, the surface of :said drill-head screw-threaded, a lcoupling-ring mounted on said threads, and a tubular drill-rod mounted in said couplingringv and havii'igits lower end serrated to engage the serrationsfon thetop of the plug,
substal'itially as shown and described.'
