COLEMAN A. TERRY, OF NEW YORK, N. Y.

CORE-DRILLDN'G APPARATUS.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed May 29, 1907. Serial No. 376,298.

To all whom it mu y concern:

Be it known that I, Conmux A. TERRY, a citizen of the lTnited States of America, and a resident of the borough of Manhattan, of the city of New York, county and State of New York, have invented certain new and useful Improvements in Core-Drilling Apparatus, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in drillingapparatus, and particularly to core drills.

My invention consists in many novel details of construction and combination of parts, and particularly in a novel form and construction of the supporting members can ployed for the drill, in an improved hydraulic feed therefor, in improved driving means including means by which the drill may be driven at will at widely different speeds, and in hoisting means combined with said driving means, all as will be fully set forth in the following specification.

In order that. my invention may be thorou hly understood I will now describe in de lai an embodiment thereof, having reference to the accompanying drawings, and will then point out the novel features in claims.

In the drawin s: Figure 1 is a view in front elevation of a drilling apparatus em bodying my invention. Fig. 2 is a view in side elevation thereof. Fig. 3 is a view in sectional elevation substantially upon the plane of the line 3-3 of Fig. 2. Fig. 4 is a detail view in horizontal section of certain parts thereof, the plane of section being taken substantially upon the line 4--4 of Fig. 1. Fi 5 is a front view in sectional elevation oi the )arts shown in Fig. 4, the plane of section eing taken substantially upon the line 55 of Fig. 4. Fig. 6 is a detail view in sectional elevation of the supporting elements, the plane of section being taken at right angles to the plane of section of Fig. 5.

F 1g. 7 is a detail view in transverse section of a regulating valve employed. Fig. 8 is a view in longitudinal section therethrough, the valve plug being shown in side elevation.

The supporting elements for the drill comprise a frame member 10, an intermediate me'mber 11, and a drill carrying member 12. The frame member 10 is mounted upon a base-plate 13, being suitably bolted thereto, and is provided with a horizontal bearing hub 14 which constitutes one of the driving shaft bearings, and an annular projection 15 disposed concentricallytherewith. The intermediate member 11 comprises a ring-like portion 16 fitted to the said annular projection 15, a vertical hub 17 located at one side of the said rin and laterally projectin lugs 18 dispose at the other sideof sai ring. ed with respect to the member 10 as to permit of its being swung with respect thereto around the axial center of the drive shaft bearing 14, the said parts being so constructed as to permit of such movement through the entire 360 degrees of the circle. In order to clamp the said parts together in whatever position they may have been adjusted, I have provided clamping bolts 26 which pass through holes in the member 10, the said bolts provided with overhanging heads 27 which engage the annular projection 15 of the member 11. Nuts 28 are fitted upon the other ends of said bolts, said nuts engaging the rear face of the frame member 10. The drill carrying member 12 is provided with vertical bearing members 19 which receive the drill rods and spindle, and with hubs 20 complementary to the vertical hub 17, a pintle pin 21 being received within the said hubs, whereby the said hubs and pintle pin form a hinged connection between the said members 11 and 12. The body portion of the member 12 has an annular flange 22 fitted to a corresponding annular flange 23 of the member 11, so that when the members 12 and 11 are brought together to a normal position, a firm and steady joint will be formed between them, the said members being clamped together by means of a clampin bolt 24 hinged tothe lugs 18, the nut of said clamping bolt arranged to engage corresponding lugs 25 with which the said member 12 is provided.

From the foregoing it will be seen that the members 11 and 12 are together so ported from the member 10, the said members 11 and 12 being arranged in their locked-together condition to be axially adjusted upon the said member 10, so that the drill rod carried in the bearings 19 may be caused to point in any direction around the circle. Once properly adjusted, the two members 10 and 11 will be clamped positively together, and the member 12 may then be swung upon the pivot in 21, so as to swing the bearings 19 out of line with the drill hole, when desired. When they are swung back. again The said member 11 is thus so mount-.

they'may be solidly clamped in position, the construction beingsuch as to causeall the parts to be held exceedingly rigid when so clamped.

Mounted within the vertical bearing members 19 is a sleeve or quill 29, the upper drill and lifting movements of the drill rods 1 have provlded suitably controlled hydraulic means by which pressure may be applied longitudinally thereto in either direction. The hydraulic means comprises two cylinders 36, 36, arranged axially in a plane with the axis of rotation of the quill 29 and carried by the member 19. Mounted in each cylinder 36 is a piston 37, each said piston secured to a piston rod 38, the upper ends of said piston rods bolted to a cross head 39. The cross head 39 is arranged between thrust bearings 40 and 41, the outer members of which are carried by thequill 29. The lower ends of the cylinders 36 are connected by means of branch pipes 42 with a common ipe 43 leading to the main controllin valve 44, while the upper ends of said cy inders .are connected by means of similar branch pipes 45 with a pipe 46 common thereto, which also leads to the main controlling valve 44. An inlet pipe 47 likewise connects with the said controlling valve, and an exhaust branch 48 leads from the opposite side of said valve, the said exhaust branch 48 itself independently controlled by means of a special exhaust valve 49. The valve plug of the valve 44 (which is shown clearly at 50 in detail views 7 and 8) has cross-over ports which are arranged to connect ports or passages leading to the various pipes 46, 48, 47, 43, together at will, the said valve plug having an operating handle 51 secured thereto, by which the same may be turned to various positions. When it is in such a position as is shown in Fig. 7 it will connect inlet through the pipe 47 with the lower ends of the hydraulic cylinders through the pipe 43 and branches 42. At the same time it will connect the upper end of the cylinders through branches 45 and pipe 46 with the discharge 48. This will admit water to the lower end of the cylinders to lift the pistons, while permittin water lifted by the pistons in the upper en s of thecylinders to escape.

If the handle 51 is moved to an upright po-;

'sition-the web of the plug 50 will close the the said bevel ports or passages leadi to both pipes 43 and 46, hence closing a mission from the inlet 47 in either direction. This is the off position. If the handle" is thrown over, to the right, water will be admitted to the upper end of the cylinders by the connection between the admission pipe 47 and the pipe 46, while it will permit exhaust by the con nection between the lower pipe 43 and the discharge pipe 48.; I have provided the valve 49 for the purpose of controllin the speed of movement of the pistons in eit er direction, as I preferdirection at all times I desire any movement at all. -The speed of movement of the pistons will necessarily be limited to the speed at which the water is allowed to exhaust, so

properly regulate the speed at all times. Thus I may delicately adjust this exhaust valve, and, having once so adjusted it, movements of he controlling lever will not change the speed of feed. I may turn the water on and oil at will to feed or stop feeding, but, as I always turn the said handle 51 the entire distance, there is no necessity of any delicacy in handling same.

I preferably provide a gage 52 by which the pressure in the upper ends of the cylinders may be noted, whereby the operator may watch the feeding pressure at all times, and regulate the graduating valve 49 in accordance therewith, while I alsoconveniently provide drip cocks 53 at the lower end of the branches 42, so that the lower ends of the cylinders 36 may be emptied at will, and a check valve 54 upon the inlet pipe 47 to prevent possible backing up of water in the pipe 47 should pressure at the source ofsupply fail.

Turning now to Fig. 2, it will be seen that the base plate 13 supports another frame member 55 in addition to the frame member 10. The frame member has a bearing 56 which constitutes a second bearing member for the drive shaft 35. The two bearing members 10 and 55 are each provided with bearings 57 arranged parallel to, and axially in line with, the bearings 14 and 56, said bearings 57 forming a support for a counter=shaft 58. This counter-shaft carries a winding drum 59, a spur gear 60, and a brake drum 61. The drive shaft 35 carries a drive pinion 62' which engages an intermediate spur 'ear 63,'said intermediate spur gear mounte to rotate with an intermediate pinion 64, in turn arranged in mesh with the spur gear 60. The clutch mechanism 65, controlled by an operating lever 66, connects and disconnects the pinion 62 into and out of driving relation with the drive shaft 35, wherebythe driving of the counter shaft 58 and drum 59 carried thereby is controlled at will, while a hand brake 67, engaging the band wheel 61, is controlled by means ably turn the water pressure full on in either that, by cutting down the discharge, I may f of a lever 68, for the purpose of retarding the rotation thereof when desired.

The apparatus last described constitutes a winding apparatus, or hoist as it is commonly called, such hoist being employed in drilling apparatus of this kind for the purpose of lifting and lowering the drill rods when necessary, but in the present instance I employ the counter shaft 58 for another purpose as well. The said counter shaft is, it will be noticed, geared down considerably with respect to the drive shaft 35, so that it'will rotate at a very much less rate of speed than will the said drive shaft. A drill of this description is sometimes used with one class of drill head and sometimes with another; for instance it is often used fordrilling under the shot system, in which case the drill should rotate at a high rate of speed. At such times I arrange and locate the bevel gear wheels 32, 34 as above described and as illustrated in the drawings, but ifa chipping cutter be employed in the drill, then the drill should rotate very much more slowly, and at such times I remove the bevel gears 32, 34: from'their present positions, to the positions shown in dotted outline in Fig. 2. Thus I remove the bevel gear wheel 34. from the shaft 35 and mount it upon the shaft 58, while I raise the position of the bevel gear wheel 32 correspondingly so as to bring the two said wheels properly in mesh. The relationship of gearing between the shafts 35 and 58 is such that the said shaft 58 rotates at just the right speed to properly drive the drill with the bevel gears in this position, so that, by this means, I provide a very simple arrangement for driving the drill at two radically different speeds, as may. be desired, without changing the speed of rotation of the drive shaft, while also providing a convenient hoist for the purposes required.

What I claim is: 1. In drilling apparatus, the combination with supporting elements comprising a frame containing a drive shaft bearing, an intermediate member fitted thereto in rotative engagement therewith concentrically with respect to the axis of the said bearing, said intermediate member havin a cylindrical bore therethrough, and a d rill carrying member pivotally connected with the said intermediate member, clamping means for securing the said intermediate and drill carrying members together, and a plurality of clamping bolts fitted in orifices in the said frame concentrically therein around the said drive shaft and between the walls of the concentric bore of the said intermediate member and the axial center thereof, said bolts having overhanging heads adapted to engage the faces of the said intermediate.
