` tain novel constructions and combinations of parts as will be hereinafter described and claimed. c

In the drawing-Figure l is a perspective view of my apparatus as in use. Fig. 2 is a detail view illustrating the bell connection with the suction pipe. Fig. 3 is a vertical section illustrating the means for securing the pumps and handle in connection with the settling chamber. Fig. 4 is a vertical section at a right angle to Fig. 3, and Fig. 5 is a detail view illustrating a clamp construction for securing the alarm bell in place.

By my invention I provide a settling chamber A, pumping mechanism B, by which to exert a constant suction in the settling chamber and a suction pipe discharging to the settling chamber, and to this extent in a broad way the present invention is similar to the apparatus shown and claimed in my former patent before referred to, but in my present invention I provide novel features which will be hereinafter described in detail.

In the drawing the settling chamber A has mounted thereon a pair of single acting pum s B and B2, which have a common supp y pipe B3 leading through the top of the settling chamber. The settling chamber is preferably in the form of a keg or barrel, this being a simple, inexpensive strong construction, which can be readily secured at almost any place. In securing the pumping devices I prefer to mount upon the settling chamber a handle bar C and to extend the arms D of a metallic bail from below the settling chamber up through the handle bar and thence through the base plates of the pumps B, B2 and secured above the said base plates by suitable nuts. This secures the pumps rmly in place and also provides a handle by which the apparatus may be conveniently moved from point to point and lifted into and out of a wagon.

The spouts of the pumps B and B2 discharge into a funnel D having a pipe D10 discharging to a trench D2 which leads to the well hole surrounding the suction pipe E, the blades of which are made sutiiciently large to cut a hole somewhat larger than the suction pipe to give plenty of passage room for the water to pass from the trench down around the supply pipe without requiring too much waste force on the pumps to draw the water down, the hole permitting the water to drop by gravity in the operation of the invention.

In the use of the apparatus the pumps are operated by one standing directly between them, and as one handle is pulled up the,

other is pushed down thus securing a steady outpour of water so the cuttings will be brought up and into the chamber A by a continuous pumping operation whereas with one pump the water will start and stop and the operation would not be continuous, and the current would not be maintained in an unbroken iiow up the pipe and into the chamber A.

Near the bottom of the chamber A I provide a discharge opening closed by a plug A which may be removed to permit the discharge of mud and other settling in the chamber, and in the top of the chamber I provide an opening closed by a bung or plug A2, which may be removed and a funnel applied for the introduction of fresh water to the settling chamber to wash the sediment out through the discharge opening near its bottom when desired.

In the operation of the described construction it will be noticed that the pumps, while single acting, are designed to be operated alternately in such manner as to produce a constant suction of the settling chamber and the pumps being mounted upon the settling chamber are arranged for operation in a vertical direction by an operator standing in such a position as to enable him to secure the maximum force upon the pump handles in the easiest manner possible. This vertical arrangement of the pump cylinders is also advantageous as compared to the horizontal arrangement shown in my patent before described, as in practice the water from the suction pump will contain at best a small quantity of gritty material, which, when a horizontal pump cylinder is used,

will settle to the bottom thereof and operate to cut the suction leathers in a short time, while in the use of a perpendicular cylinder the gritty particles will float loosely throughout the water and do not accumulate at any one point.

The suction pipe l@ may be made in sec tions suitably jointed together and is lowered into the well hole and sections may be supplied from time to time as desired. To the upper end of the vertical suction pipe l connect by a joint F] one end of a pipe section F12, to the other end of which is connected a flexible hose F, which leads thence to the inlet F of the settling chamber. The pipe section F2 and the hose F are supported above the ground by a carrier arm G foldably connected at one end at G to an upright stake K, which may be driven in the ground, the joint G including a bolt and clamp nut so the carrier arm may be held in position for use as shown in Fig. 1, or the nut may be loosened and the arm folded alongside the upright for convenience in transportation. rFlic arm G is provided with a series of notches and ropes 1 and l connecting respectively with the pipe section E2 and the hose F and are knotted at- 13 and l* to interlock with the notched carrier arm in order to hold the parts E2 and F aboi'e the ground and avoid the injury thereto resulting` from resting and dragging upon the ground in the operation of the invention.

The joint E is provided with an oil cup E10, in which a stiff greasy oil may be used to lubricate thc joint E and t-hus render the movement thereof easy and aid in maintaining an air-tight joint at such point, and l also find it advisable to provide an oil cup E11 in the suction pipe lll a short distance below the joint E to aid in lubricating the said oint and securing an air-tight connection at the joint Fi will be understood from Fig. l of the drawing. This suction pipe Fi may be coupled at E12 to the pipe Sections extending down into the well'and these latter pipe sections may be added from time to time will be readily understood by those skilled in the art.

1n order to supply an alarm when water is struck, 1 support a bell J rigidly in connec` tion with the suction pipe in such manner that the clapper J of the bell may be operated by the vibration of the suction pipe. l prefer to connect the bell detachably with the suction pipe and this may be effected by a stout spring clamp J 2, as shown in Fig. 5, or by a bolted construction, as shown in Fig. 2 of the drawing.

1n digging wells through some sections of the western portion of this country, it has been found by the applicant in his extended experience as a well digger that at times a sand is struck which the applicant designates, for the purpose of reference, a hidden sand because its characteristics are not fully appreciated by all well diggers. This sand is a very fine sand which does not have the appearance of being a water bearing sand as it is discharged from the well in digging the same. Because of this fact, this sand is frequently overlooked by well diggers whereas, as a matter of fact, it is a water bearing sand of a fine quality and if when reached the well point were applied, it would, in many cases, give an ample supply of water. @n the other hand, if this sand is passed in the operation of digging the well, it always happens that the well must be dug very much deeper in order to secure a supply of water. rlhis so-called hidden sand is found to possess the quality of setting up a vibration in the pipe to such an extent as to impart to the bell a ringing operation, the bell being caused to flutter with steady regularity and uniformity on the operating movement in one direction of the well tube and with a corresponding steady regularity and uniformity on the return movement of the well tube as the tube is oscillated back and forth in the digging operation. 1t is found by practical experience in the operation of digging Wells that the sand referred to will cause the bell to ring in the peculiar manner described and give warning to the digger that a water bearing sand of high quality has been struck so the tube may be removed and the sand point applied in order that the supply of water may be availed of. 1t is found, also, in practice that the water bearing sands other than that referred to as the hidden sand, will not give the described characteristic regular and uniform flutter to the bell to indicate the discovery of the desired water bearing strata.

From the connection at F a supply pipe F2 leads into the settling chamber and upwardly therein and has its upper end returned, discharging the water downwardly at about the center of the settling chamber near its upper end. This returned nozzle or discharge end of the supply pipe starts the water and sediment toward the bottom of the chamber while the current spreads and turns outwardly toward the walls of the chamber and then rises slowly in response to the suction of the pumping devices connected with the upper end of the chamber A as before described.

rl`he bell will ordinarily ring in the usual operation of drilling, the ringing on striking` the peculiar sand before described being different and clearly distinguishable from the ordinary ringing of the bell.

1n operation it may be necessary, in some instances, in start-ing, to work the apparatus, to supply water to the chamber C, and it will be understood that from time to time the well tube or suction pipe can be oscillated or turned by a pair of tongs or suitable devices as is usual in the operation of drilling wells.

As in the operation of the invention covered in my former patent, it will be noticed that the current of water outside the well pipe is continuous in its motion and is secured in a simple way and the upward current within the well tube is also continuous because of the alternate operation of the single acting pumps and the suction produced thereby within the settling chamber, the arrangement being such that the earth, cuttings, gravel, etc. will not get to the pumping devices and therefore will not interfere with the proper operation of said devices when arranged as before described, and in operation water may be supplied from time to time to compensate for the slight absorption of the water by the ground.

It will be understood that the in-take of the chamber A may come in at various points, and I have indicated in dotted lines, Fig. 3, the said pipe coming in from the side of the chamber near the top. In Fig. l, I show a bucket L suspended from the carrier arm G, and adapted to contain water which may be conducted through a little hose L', to the sand dump hole closed by the plug A', so that when the plug is pulled out, if the settlings dump slowly the little hose L may be utilized to discharge a jet of water into the dump hole which will at once loosen the muddy contents, and start them to discharge through the dump hole, the bucket being supported at a suicient height to secure the fall necessary to this operation.
