DRILL.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application led January 25, 1913. Serial No. 744,139.

To all whom t may concern.'

Be itpknown that I, FRED R. WEATHERSBY, a citizen of the United States, and a resident of Houston, in the county of Harris and State of Texas, have invented an Improvement in Drills, of which the following is a specification. p

My invention relates to drills for general use -and more particularly to drills especially adapted for use in connection with rock and earth formations.

The 'more particular purpose of my invention is to provide a drill in which there are a number of separate cutters detachably secured upon a head, the various parts being so arranged and connected as to present a number of advantages.

Reference is made to the accompanying drawings forming a4 part of this specification and in which like letters indicate like parts.

Figure 1 is a substantially central vertical section through my improved drill and is taken upon the line 1-1 of Fig. 2, look ing in the direction of the arrow.' Fig. 2 is an inverted plan of my improved drill. Fig; 3 yis a top plan view of the drill, some of the cutters and` parts associated therewith being removed.` Fig. 4 is a detail showing in plan the cutter disk forming a part of the drill. Fig. 5 is a perspective view showing one of the cutters removed. Fig. 6 is `a detail showing another form of cutter which is provided with a single cutting tooth. Fig. 7 is a perspective showing another form of cutter which in this instance is provided with two cutting teeth. Fig. Sis

a perspective of the central cutting member vwhich serves the double purpose of a centering bit and acutter.

The shank 9 carries an annular flange 10 i integral with it. A disk 11 having the same by a cutter 14, the latter being provided with a stem 16, the upper end of which is threaded and fitted with a nut 17. This nut is housed in a countersink 16, as will be uns' derstood from Fig. 1. f At 18 are shown four cutters, each havmg a length nearly equal to the radius of the disk 11 and being provided with teeth 19. Each cutter 18 is provided with two stems 20, 21, these stems being square in cross section 'except at their upper ends 22, these ends being threaded and fitted with nuts 23. The cutters 18 are further provided with square stems 24, the upper ends 24aL of the latter being fitted with nuts 25. These nuts Vare housed in countersinks 24b within' the disk 11.

I provide a .number of cutters 26 of the type shown more particularly in Fig. 7. Each cutter of this type has two teeth 27 and -a `square stem 28, the latter at its upper end being rounded and threaded at 29. I alsovprovide other cutters 30 of the type shown in Fig. 6. The cutter 30 is provided with a single cutting tooth 31 of considerable width. It is further provided with a stem 32 which is square in cross section and carries a rounded threaded portion 33 at its upper end.

For accommodating the cutters 26, 30, I provide the disk 11 with square holes, 35, spaced systematically with reference to the other holes, as will be understood from Fig. 4.

In assembling the various parts, I first take up the cutters 18 and pass the stems 24 through the disk 11 and, by applying the nuts 25, secure the cutters 18 to the disk. I next extend the stem 16 of the cutter 14 through the middle hole 13 of the disk 11 and by applying the nut 17, I secure this cutter 14 iirmly to the disk. I next place the disk 11 'against the flange 10, turning the disk, if necessary, to some extent so as to bring the stems 20, 21, into registry with the holes in the disk 10. The stems 20, 21, being now threaded through the disk 10, the nuts 23 `are applied, as indicated in Fig. 1. A

It will be noted that the stems 20, 21, carried by the cutter 18 holds the disk 11 upon the fiange 9, whereas the stems 24 merely hold the inner ends of the cutters 18 tightly 'against the adjacent` portions of the disk 11, the stems 24 having no immediate connection with the shank 9 or the iiange 10. Similarly the cutter 14 is not connected with the shank 9 or the disk 10.

Whenever the disk 11 is' taken ofi. none of the cutters 14, 18become loose relatively to thedisk. It is different, however, with -the cutters 26, 30. The stems 28, 32, of these cutters are analogous to the stems 20, 21, of the cutter 18 and are held in position by aid of nuts 23. When, therefore, the nuts just mentioned are taken olf in order to dis- 5 engage the disk 11, the cutters 26,- 30, are

loosened relatively to the disk.

Extending entirely through the drill are holes 34, through which waterdlows in order .to wash away the debris.

serves not only the purpose or a cutter but also that of a centering bit around Vwhich the various other cutters revolve in circles whiley the drill is in action.

it will be noted that the stems 16, 24, -which are comparatively short and are to- -tally disconnected from the shank 9 and disk 1.0, are located comparatively near the center of the drill.v On this account the leverege ,exerted on the stems in question and parte carried thereby is considerably less `..th'an that `t0 which the longer stems are exposed. This fact gives my construction a Z peculiar advantage in that the stems 20, 2l, Which snstain relatively the, Veatest leverage, are .secured firmly to. t e annular ange l0 and thus enabled to stand the `excessive strain thrown upon them.

The various cutters are removable .and replaceable independently .of each other.

rlhe operation of my device is as follows: The parts being arran ed and assembled as above described, .the ank 9 is connected with the operating mechanism oi the drill The cutter 14; lcarrying the two blades 15v and being forced against the earth is caused to rotate. The various cutters are thus caused to revolve, the teeth 9 being brought into operative engagement with the earth, rock or other material -to be cut.

"I do not limit myself to any special shape for the teeth; neither do l limit myself to .the precise .construction and arrangement shown, the scope of my invention being com mensurate with my claims. Having thus described my invention, what l1 claim as new and desire to secure by Letters Patent is as follows l. A. drill comprising a revolulole member, a disk engaging the same and .a cutter provided with stems, one of said stems being secured to said disk and another of said stems extending through said disk and being secured to said revoluble nlenrber.y

2. A drill comprising a revoluble member, a ldisk provided with holes 4and with countersinks merging into some osaid holes, cutters provided with stems extending through all of said holes, means for securing some of said stems .to said revoluble `member, and nuts located within said coun- AteI'SnkS and engaging the stems extending through the holes into which said counterlSinks merge.
