OTTO 'WILHELMI, OF LUCERNE, SWITZERLAND, ASSIGNOR OF ONE-HALF TO THE FIRM OF INTERNATIONALE SIEGWAR'TBALKEN-GESELLSCHAFT, OF LUCERNE, SWITZER- LAND.
TOOL FOR PRODUCING WELL-HOLES, POLE-HOLES, AND THE LIKE.
Application filed January 2, 1914.
To all whom it may concern:
Be it known that I, O'r'ro \VILHELMI, a subject of the German Emperor, and resident of Lucerne, Switzerland, have invented an Improved and Novel Tool for Producing ell-Holes, Pole-Holes, and the like, of which the following is a specification.
When producing holes for wells, piles, and the like, by aid of a driving tube, the ground is loosened and displaced by means of the material, for instance water or a plastic substance, taking up the pressure or receiving the blows of a monkey, the ground in question being that below the lower edge of said tube, so that this latter can penetrate more easily into the thus treated ground. \Vhile, now, for instance, a concrete pile to be inserted into the hole is provided with a shoe, this latter may be dispensed with if the driving tube itself is appropriately shaped at its lower end. My invention relates just to this point.
In order to make my invention more clear, I refer to the accompanying drawing, in which:
Figure l is a perspective representation of the lower end of a driving tube constructed according to my invention; Fig. 2 is a plan of this tube, seen from below; Fig. 3 is a representation similar to Fig. 1, showing a slightly modified form of construction; Fig. 4 is a horizontal section through Fig. 3; and Fig. 5 is a vertical section in line mcc of Fig. 3.
The tube a is cut out at its lower end at two places opposite to one another, the size and position of the cut-outs Z being such that the remaining parts form wedges 0, the edges of which lie in plain or in curved planes. *When the wedges are forced into the ground and, for instance, liquid concrete is introduced into the tube and the concrete is subjected to pressure, it is forced out of the tube through the cut-outs Z, along the whole length of the latter, being thus caused to assume the shape of a pile-shoe because it is retained between the cut-outs by the wedge-shaped parts 0. The thus obtained concrete shoe penetrates into the ground like a pile shoe, a special and expensive pile shoe which otherwise would be intentionally lost becoming, therefore, unnecessary. Besides this advantage another one resides in the fact that the lateral pressure produced by Specification of Letters Patent.
Patented Nov. 17, 1914.
Serial No. 810,020.
the height of the column of liquid concrete, multiplied by the pressure exerted upon it, has a widening effect upon the ground at the cut-outs of the tube, whereby the further penetration of the tube into the ground is considerably facilitated.
The technical progress and the novel effect is based thus upon the widening action of the concrete column and the lower end of the driving tube; further in the formation of a concrete shoe at the foot of the column, and besides, in the possibility to reduce the friction between the sinking driving tube and the ground by such simple and cheap means as are hereinafter described. For this purpose I make use, for instance, of iron widening rings or bows p which are attached to the lower part of the tube a, preferably just above the cut-outs Z, or at their upper ends respectively, the arrangement being such that said rings or bows get down together with the tube, but remain behind in the ground when the tube is withdrawn.
In the form of construction shown in Figs. 1 and 2, the widening ring consists of two halves p 0 having hook-shaped ends 9 that reach into the interior of the tube and form, in a sense, coupling parts by means of which the ring halves are compelled to move down together with the tube.
In the form of construction shown in Figs. 35, the widening ring 39 consists of one piece which is prevented from upward displacement relatively to the tube by lugs 1" afiixed to the tube; when this latter is withdrawn, the lugs leave the ring, leaving this behind in the ground. The lugs 1* may be aifixed to the tube by rivets or the like, and their con figuration and dimensions is or are preferably such that they ofi'er as little resistance as possible to the movement of the tube. "he rings or ring parts may be made of round iron or section iron. Owing to these parts being situated at the outer side of the tube, the hole produced receives a larger diameter than has the tube, there arising consequently but very little friction on the tube getting down into the ground.
Having now described my invention, what I desire to secure by a patent of the United States is:
1. A tool of the character described, comprising a driving tube out out at its lower end on opposite sides, wedges formed by said cut-outs adapted to form a concrete shoe, and means for reducing the friction between the sinking driving tube and the ground, substantially as described.
2. A tool of the character described, comprising a driving tube .cut out at its lower end on opposite sides, wedges formed by said cut-outs adapted to form a concrete shoe, and rings upon the outside of said tube near its lower end secured against upward movement for reducing the friction between the sinking driving tube and the ground, substantially as described.
3. A tool of the character described, comprising a driving tube out out at its lower end for constituting a means for forming a concrete shoe, and bi-partite rings bent with their upwardly directed ends into said tube for preventing their upward movement, said rings reducing the friction between the sinking driving tube and the ground, substantially as described.
4. A tool of the character described, comprising a driving tube cut out at its lower end on opposite sides, wedges formed by said cut-outs, adapted to form a concrete shoe, rings upon the outside of the tube near the lower end thereof and means for preventing the upward movement of said rings and for permitting them to remain in the ground after the removal of said tube, substantially as described 7 In testimony whereof I affiX my signature in presence of two witnesses.
