IMPROVEMENT IN DRIVING WELL-TUBES.

The Schedule referred to in these Letters Patent and making part vof the `same.

To all whom it 'may concern Y Be it known that I, D. R. KNIGHT, of Akron, in the county of Summit, and State of Ohio,'have invented certain newand useful Improvements in Driving Pump- '.lubing; and I do hereby declare that the following is a Vfull and complete description ot' the same, reference being had to the accompanying drawings, making a part of this specification, in which--A Figure 1 is an outside view of the pump.

Figure 2, a detached section.

Figrue 2, a vertical transverse section.

Like letters of reference refer to like parts in the several views.

This invention relates to a combination of tubing, arranged, one within the other, and armed with a sharp, rounded point, for penetrating the ground into which it is driven, thereby saving the expense of boring or digging for water.

In iig. 1-

A represents a shell, or' the outertube, which consistsof a section of ordinary iron tubing or pipe, in which is fitted closely, but not tight, a tube, B, a detached view of which is shown in fig. 2.

In each four sides of said tube is sunk'a recess or chamber, C, the bottom of' which is pierced with a series of holesfa, iig. 3, and which are connected to each other by oblique shallow grooves D,l the purpose 0f which will presently be shown.

The lower end of said tube is armed with a sharp,

rounded point, E, the largestA diameter of which being a little more than the diameter of the collar F,'whcre by the splicing together ofthe several scctionsof tubing is made, and which follows the point-into the ground without crowding, v

G, fig. 2, is a slot, cut, in a spiral direction, in the side ofthe tubing.

Into said slot is projected the end of the pin b, penetiating the shell or outer tube A, thereby connecting the two sections to each other. v

One side of the outer tube is pierced with a series of holes, c.

From the upper side of each holel proceeds an inclined tapering groove, e, the purpose of which will hereinafter be shown.

of this arrangement of tubdition, it is driven into the ground, a successionof length of pipes beingadded, by means of the collar F, as fastv as the descent of the lower section may require, until the desired depth is obtained. The closed holes c arethen brought iu open relation to the holes a of the inner tube, by drawing upward the outer tube, or by driving down the inner'b'ne, by inserting a, rod therein of sutcient length to reach down to the point, the result of which will be to either turn the outer tube, or the section to which the point is attached, by virtue of the pin b moving in the spiral slot above described, the length of said slot being just sucient to bring the series of holes in each section in open relation to each other, thereby allowing the water to flow in from the outside, thence upward in the tube.

The inclined tapering grooves c are for the purpose sof preventing the dirt, sand, Src., from lodging in vthe holes while the tubing is being driven into the ground. Their-"slanting nature allows the dirt to slide upward flow intovthetubc with greater facility in the event the holes become obstructed with dirt, &c.

The oblique grooves in the innner tube, connecting with greater freedom should the chambers and holes become charged withobstructions.

What I claim asmy invention, and desire to secure Vby Letters Patent, ise 1. The recesses or chambers C, oblique grooves D, and inclined tapering grooves e, combined and arranged, in relation to the tubes A and B, substantially as and for the purpose specified.

in combination with the tubes A and B, in the manner as and'for the purpose set forth.
