UNITED ISTATES PATENT OFFICEO JAMES H. SOUTH, OF MONDAMIN, IOWA.

BORING SPECIFICATION form'ng part of Letters Application filed April To all whom it mcy"concerm Be it known that I, JAMES H. SOUTH, ot" Mondamin, in the county of Harrison and State of Iowa, have invented certain new and useful Improvementsin Boring Wells; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings,which form part of this specification.

My invention relates to an. improvenent in the method of lowering tubing into wells; and it consists in pressing the sections of the tube into the well by means of rods which havethe derrick fastened to their upper ends, whereby nearly the whole weight of the derrick is utilized in pressing the section' into position.

It further consists in the arrangement and combination of parts, which will be more fully described hereinafter.

The object of my invention is to utilize the weight of, the derrick in forcing the sections of tubing into position, and especially where quicksand is encountered, and where the hole, as it is bored, would rapidly fill up if the tubing were not quickly inserted into position.

Figure l is a side elevation of my invcntion. Fig. 2 is a perspective of the same. Fig. 3 is a plan View of the bottom piece of the well.

A bucket-auger is' employed in boring the hole for the well, and the sections of tubing B, of any desired length, are then inserted into the hole which has been dug by the anger. This anger will be operated in the usual manner, and the derrick, which is placed over the well, will be provided with a windlass for drawing up the dirt from the hole in the angerbncket. After the hole has been bored a suitable distance one of the sections of tubing is inserted into the hole, and then the pressure rods C are applied to its top edge. These rods have their lower ends forked, so as to catch over the top of the tubing, wherebythey are prevented from slipping off, and their upper ends are also forked, so that either one ot' the prongs will catch in any one of the links of the chains D, which are used in connecting the upper ends of these presser-rods with the presser-levers E. The two presser-levers have their ends united together by means of the me- WELLS.

tallic plate F, and which plate has a hole made through or in it to receive the lower end of the braced post G of the derrick. To these two presser-levers the chains are fastened at any suitable point, and then the chains are hooked or fastened to the tops of the two presser-rods, as shown in Fig. 1. The bracepost of thederrick is lifted from the ground, and its lower end, provided with an iron pin, is placed in the hollow in the plate which connects the two ends of the presser-levers together. As the two presser-lcvers are raised above the ground by means of the chains, and as the derrick is thus made to throw the greater part of its weight upon these two lcvers, it will readily be seen that this weight is transferred from the presser-rods to the top edge ot' the section of tubing which is being inserted in position in the well. After the auger has become filled with earth and the windlass is used to raise it upward, the whole weight of the au ger, together with the friction in raising it upward, is added to the weight of the derrick in forcing` the section of tubing into place.

In certain sections of the country, in boring wells quicksands are encountered at different depths, and which, unless the tubingis quickly inserted into place, will so completely fill up the hole which has been dng as to make the digging of the Well a very difficult and costly operation. By thus having the sections of the tubing placed one above the other and the whole weight of the derrick constantly restin g upon them, as soon as quicksand is encountered the weight and pressure of the derrick will instantly force the section downward, so as to cut off the flow of sand into the well. In this m-anner, no matter at what depth the quicksand may be encounteredit can be so easily controlled that it willinterfere very little with the digging of the well. After the well has been dug to a suitable distance a bottom, I, made of strong wood, iron, or any other suitable metal, may be inserted in position, and through this bottom will be nade any suitable number of openings, which are covered' with wire-cloth. These sections of wire-cloth allow water to freely pass up into the well, but will prevent quicksand, dirt, or other similar substances from being carriedinto the well in such qnantities as to fill up the well.

2. The combination of the sections of tubing with the presser-rods, the presser-ievers, the 15 connecting-chains, and the derrick, substantiaily as described.

In testimony whereof I affix my signature in presence of two witnesses.
