DISCHARGING MECHANISM FOR ROTATING BORING-RODS.

$PECIFICATION forming part Of Letters Patent No. 650,988, dated June 5, 1900.

Application filed Juno 9, 1899. Serial No. 719,985. (No model.)

To all whont it nutty concern:

Be it known that I, ANTON 'RAKY, a subject of the King of Prussia, German Emperor, and

a resident of Erkelenz, in the Province of 'the :Rhine, German Empire, have invented certain new and useful Discharging Mechanism f or Rotating Boring-Rods, of which the fol-f lowing is an exact specification.

The present'in-vention relates to an im-f structions the rope was fixed to the boring-rods and was led over a roller arranged in the boring-tower to the counterweight, which could;

move freely within a slide arranged on the boring-tower. In these arrangements the boring-rodscould only elfect slight movements and very often had to be brought out of ac tion for a long time when the dischargingweightwas to be regulated. Generally the boring-rod after having bored a hole of about one thousand feet depth had to be stopped and the counterweight had to be regulated.

The advantage of my invention is that depths of great dimensions can be bored continually, the regulation of the counterweight being effected during the operation of the apparatus.

In order to render my invention more clear, I have represented, diagrammatically, three forms of execution in the accompanyingdrawings.

Figure 1 illustrates an elevational view of my invention. Figs. 2 and 3 show the same on alargerscale. Fig. 4 is a top View of Figs. 1 and 2. 4

The counterweight g is suspended between two cylinders and Z. The cylinder is is connected with a cylinderf, upon which is wound the rope d, carrying the boring-rod a. Upon the second cylinderl the rope is Wound in length corresponding to the depth of the hole to be bored, (generally corresponding to the length of the boring-rod.) The cylinder Z can be rotated by means of a foreshaft n, so as to bring down again the weight 9 when it has attained its highest position and for the purby means of a gearing of conical wheels 0.

pose of allowing a corresponding length of rope to be unwound. Thus the rotating boring-rod can descend more and more as long as rope is wound upon the roller Z. When this rope is unwound com pletely, the boring apparatus must be stopped. Then the cylinder 71'; has to be uncoupled from the cylinder f in the manner usually employed, and the appaof execution is clearly represented in Fig. 3

of the accompanying drawings.

The boring-rod a reposes rotatably within a frame I). The rotating motionis given from the engine and transmitted to the boring-rod A rope 01, running over the roller 6, arranged in the boring-tower, Fig. 1, carries at its one extremity the boring-rod and at the other is wound upon a cylinderf.

The counterweight g is suspended on a roller g of the rope 72 This rope h is conducted over two rollers 1i and i, fixed to the frame of the boring apparatus, and at the oneside leads to a cylinder 70 and at the other side to a cylinder Z. In this form of execution the rope his not wound directly upon the cylinder carrying the rope d of the boring-rod, but the two cylinders taking up the carrier-rope for the boring-rod and the rope to which is suspended the counterweight are brought into connection by a fore wheel m. This intercalating of a fore Wheel offers the great advantage that the discharging of the weight of the boring-rods being comparatively great in a certain depth can be effected Very easily. The cylinder Z, supporting the rope h to be unwound, can be fixed by means of a worm-wheel n or can be rotated by the same. Also the cylinder 75 can be rotated in both directions by means of a hand-wheel 1), connected to the cylinderk by an endless chain 0.

The operation of this apparatus is as follows: Suppose the weight of the boring-rod in a certain depth to be 4,405.3 pounds, the proportion of transmission of m from k to f being as one is to twenty, not considering the resistance occurring by friction, the counterweight suspended on two sides only has to amount to 440.53 pounds in order to be equal to the weight of the boring-rod. By altering the effect of the counterweight the operator is enabled to make the borer descend by its own weight, and at the same time the pressure which exercises the borer upon the rod can be regulated at will. It now the counterweight is in its lowest position and the boring mechanism is actuated, the boring-rod will descend slowly and the rope d will be unwound from the cylinder f. Thereby the cylinder is rotated, so that the rope h is wound up and the discharging-weightrises. Afterthe discharging-weight has attained its highest position it must be brought back again into its original position by rotation of the cylinder Z, as before described. This rotation of the cylinder Z is effected by the worm-wheel n. The pressure of the boring-rod upon the rock can be regulated by means of the endless chain 0, moved by the hand-wheel 1).

It very often happens that the borer suddenly meets a hard piece of rock, so that a great pressure is necessary to attain a good boring effect. Such hard pieces of rock generally being small, it is inadvantageous to modify the pressure of the borer by modification of the counterweight. In such cases the effect of the counterweight can be weakened or lessened by the hand-wheel p in increasing (by means of the fore wheel m) the pressure of the boring-rod. It is quite evident that in the contrary eventi. 6., when the boring-rod meets softer pieces of rock the eifect of the counterweight can be increased, and the pressure of the boring-rod will be weakened.

Figs. 1 and 2 represent an elevationalview of a modified form of execution of my invention. The general arrangement, the operation, and the effect of this apparatus are the same as represented in Fig. 3. A difference only consists in the special arrangement of the rope 7t, carrying the counterweight.

While in Fig. 3 the rope h is wound upon special cylinders 70 and Z, in this construction no cylinders are used for this purpose, but the rope is wound upon simple disks. The rope is endless and runs from the disk 70, coupled to the cylinder f, over the roller i to the carrier roller 9 of the counterweight. From there it is conducted over the roller 1) to the disk Z, fixed or rotated by the worm-wheel gearing n. A guide-roller q presses the rope it against the disk Z andleads the same downward and to arollerr,so thataloop h is formed between these rollers. The efiect is accurately the same as described in Fig.3. In the position represented in Figs. 1 and 2 of the accompanying drawings the dischargingweight is lifted when the boring-rod descends deeper into the hole, and during this operation the loop h will be increased. When new the weight g has attained its highest position, the disk Z is rotated in the direction of the arrow, whereby the loop h is shortened and the counterweight is brought down again, so that the disk 7c can continue the lifting of the apparatus.

Having thus fully described the nature of this invention, what I desire to secure by Letters Patent of the United.States is In a discharging mechanism for rotating boring-rods in apparatus fordeep borings, the

combination of a cylinder f taking up the free extremity of the carrier-rope with a discharging-weight g suspended on arope hrunning over cylinders 70 and 6, means to connect the cylinder 76 to the cylinder f, means to rotate the cylinder Z and to fix the same, an endless chain 0 led over the cylinder 70, a hand-wheel p for giving motion to the chain 0, for the purpose and substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

ANTON RAKY.
