SPECIFICATION forming part of Letters Patent No. 257,896, dated May 16, 1882.
Application filed February 13, 1882. (No model.)
To all whom it may concern Be it known that I, HENRY 0. REIGHARDT, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented a new and useful Improvement in Core Breakers and Lifters, of which the following is a specification.
My invention relates to improvements in core breakers and lifters for use in diamond drilling machines, and its Objects are to break off the core at a certain and definite point, and then seize it and hold it firmly while it is being lifted from the drill-hole, the whole device working automatically in a certain and effective manner. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a vertical section of a diamonddrill bit with core-barrel shell having my core breaker and lifter attached. Fig. 2 is a horizontal section through the line O O in Fig. 1. Fig. 3 is a full front view of an expansion steel cylinder, (marked D in Fig. 1;) and Fig. 4 is a vertical section of a diamonddrill bit with core-barrel shell andinside corerepresented at B, while G is the core-barrel grooved or roughened.
shell. A is my device for breaking and lifting the core, and it is secured to B and G by means of screw-threads, as shown. The section A is turned or chambered out, as shown at E, forming an inclined surface, which is D is an expansion steel cylinder, having a lap or slidejoint, d, as shown in Fig. 2. In this cylinder I form three slots oropenings, in which I neatly fit three steel springs, 1 1 1, which are riveted or otherwise secured to the cylinder at 4. To each of these springs I attach a toothed wheel, 2,"the bearingsof which run in the arms or lugs 3 3. Now, it.will be seen that the opening through which the core is to pass from the drill-bit up through the core-barrel shell is clear and unobstructed. There are no openings or obstructions to till up or prevent while the shells A and O and the bit B are rising. The wheel 2 engages in the roughened or grooved surface of the inclined chamber E, and moving down the inclined surface is forced into the core, taking a firm hold, which enables the core to be lifted out of the drill-hole along with the whole device.
When the coreis unbroken, and itis desired a) break it, one of the toothed steel wheels 2 is removed, and then by operating the device merely as a lifter with the other two wheels the core will be forced to one side and broken off, and may then be lifted out without further trouble or manipulation.
I prefer to form my springs 1 1 1 of separate pieces of steel, although they may be made a part of the cylinder by cutting out around the outline of the spring, except at 4, where the cylinder is left intact. fer-my toothed wheels with rounded faces.
When drilling through soft or brittle substances, what is called a double core-barrel is often used. This is represented in Fig. 4, and my invention is applied to that I also pre manner of drilling by simply increasing the size of the wheels 2 2 2 and forming an opening or slot in the inner core-barrel, X, as shown at X. The operation is similar to that heretofore described.
In most cases my device as shown, having three springs and three wheels, answers every purpose necessary; but I do not confine myself to the use of any particular number, as the IOO A, having the chambered recess E, with in- D, the springs l l 1, the toothed wheels 2 22, clined, surface roughened or grooved, with in combination with the inner core-barrel, X, which the wheels 2 2 2 engage, and are forced having slots X X X, as shown and set forth. I0 downward and outward against the core, as HENRY O. REIGHARDT.
