PRESLAR, otal engagement of the walkingbeam (at a citizen of the United States, residing at Cinrear) and the derrick, (in front,) as hereincinnati, in the county of Hamilton and State after described. The various counter-shafts 5 of Ohio, have invented new and useful Imcarrying the pulleys, gears, Lbs., constituting 55 provementsin Apparatus forSinking Tubular the operative mechanism are arranged across lVells, of which the following is a speciiicathe frame A in bearing-supports clamped to tion. the sills and uprghts, as hereinafter more My invention relates to well-sinking appaparticularly set forth.

The frame A is constructed of apparatus-cas,forexample, inatunnel, cave, 90 lower and upper side sills a a2 a3 a4, correor depression of the earth or where thc opersponding end or cross sills a5 a6 al as, corneration is to be conducted from a float upon the uprights b b2 b3 b4, and intermediate uprights water, dac. A more specific referenceto this e556, all of wrought-iron pipe, united at j uncfeature will be introduced later.

45 tions by malleable-iron iittings c, similar in Thecounter-shafts,a`salreadyindicated,are 95 form to ordinary pipe-fittings. The eornermaintained in supporting-brackets clamped uprights b b2 o3 b are extended upward a conto the sills or uprights. As` these supportingvenient distance and diagonally braced by brackets are all of essentially the same conbraces d from the upright sills, and at their struction, the support shown in Fig. 6 will Y 5e upright extremities are provided with fittings serve as a type for all. It consists of a subme stantially-triangularsupporting-block @,having a' grooved base provided with screw-caps e e', adapting it to be clamped to one of the sills or uprights, and a cross-perforation e2 at the apex, hollow and babbitted for the journal-bearing of a shaft. Bearings of substantially the same construction, differing in size and strength according to the use to be made of them, are provided for each shaft. These shafts in the complete apparatus shown consist of a general driving-shaft f, to which initial power is applied from a motor, (not shown,) shafts g 7L for driving the main-hoist reel-shaft fi and sand-pump reel-shaftj, respectively, a crank-shaft k for operating the walking-beam, (with an attendant fly-wheel shaft l for regulation,) and aremovable shaft for driving the core-drill. The shaftf is located near the end of the frame farthest from the well and is supported above the sills a3 0,4, and is the main driving-shaft to which the powerisinitiallyapplied. Itcarresanormally loose driving-pulley p', rotatively connected to or disconnected from the shaft by a friction-clutch device, a preferred construction of which is shown in Fig. 8, consisting, essenlially, of radial plnngers movable outward andinward in bearings upon radial arms y] of a fixed hub y by means of toggle-levers a', pivoted to a longitudinally-sliding collar, the plungers terminated by friction-blocks lz,con tacting against the under side of the rim 0f the pulley p'. The particular construction of the device, independently of its use here, I havemade the subject of a separate application pending herewith, and therefore need not further describe the same. The sliding collar operating the clutch device is operated by a bell-crank lever o and a rod connection 02, Fig. 5, extending to the front of the machine-frame, and by these means the rotating power can be instantly or gradually engaged or disengaged. The shaftfalso carries a fixed friction-pulley p2 for operating the reels, a chain-gear for operating the walking-beam mechanism, and a belt-pulley p3 for operating the core-drill, and, when necessary,

a chain-gear for operating a pump, as in Fig. 5, and a capstan-pulleyp5 for general use.

Below and at either side of the shaft f, in bearings suspended below the sills a3 a4, are the shafts g h, the first having a pinion and spur-gear connecting with a shaft z', supportedin bearings upon the sills a. a2, and the secondhaving a chain-gear connection with a shaftj, mounted Lin bearings upon the uprights b5 be. The shafts t' and j carry windlasses ij for rope, the former operating the sand-pump and the latter being the main hoist for lifting drills, &c. The shafts g and h are journaled at their forward ends in eccentric-blocks carried in their bracket-bearings e, which eccentrics project laterally through the bearings and are provided with cranks g' and h', coupled to rods g2 h2, attached, respectively, to hand-levers g3 h3, mounted on the frame A at the front. By the manipulation of the hand-levers friction-gears g4 h4 upon the shafts g h, respectively, are brought into contact with the fixed frictional pulley p2 on shaftf, and the Windlasses t" j are thus actuated, as desired. By a reverse movement of the levers g3 h3 the friction-gears g4 h4 are seated against fixed brake-shoes g5 h5, attached to the upright b3 and the sill d3, respectively, whereby the nnwinding of the windlasses may be safely regulated or in-` stantly stopped, as desired.

The walking-beam is constructed of two parallel pipes Z910, pivotally connected at the rear to the uprights b3 b4 by the special fittings 703701, from which pivotal connection the pipes bw extend forward to the front of the frame A. A Wooden cross-brace b is secured to the pipes p10 near the front, to which brace pitmen 7a2 are pivoted, extending downward to terminal cranks 7c upon the shaft lc, journaled in clamp-bearings e, suspended from the upper sills a3 a4. The shaft 7c is driven by a chain belt from the chain-gear p3 on the initial counter-shaft f, and to regulate its motion and that 0f the walking-beam it carries a spur-gear 7c3, meshingwith a spurpinion Z' upon the shaft l, journaled in adjacent bearings clamped to the sills a3 a4 and carrying a fly-wheel Z3.

The derrick N is built of two side pieces n n, suitably braced across, converging upwardly, and provided at the lower ends by special fittings n, pivoted to fittings m2., secured to the uprights b b2 in such manner that the fittings n socket into the upper ends of the uprights when elevated, as shown in Fig. l, in which position they are held by diagonal braces n3, bolted to the upper ends of the uprights b3 b4. Pulleys p6 at the top of the derrick N on the'cross-piece bu and p8 and on a cross-bar connecting the fittings m3 m4 are provided for the elevating-rope from the reel j', used in operating or lifting the drill. The reel being held stationary, the vertical movements of the walking-beam cause a relative lengthening or shortening of the drill-suspending rope 4"", which lifts and drops the drill alternately. The rope r2 from the sand-pump reel t" passes directly to and over a pulley p9 at the top of the dei-rick adjacent to the pulley p, and thence directly downward to engagement with a sand-pump or with the rotary drill s'. (Shown in Fig. l.)

In connection with these mechanisms l have provided a core-drilling device which may be attached to and detached from the inachine, as desired. This is illustrated more particularly in Figs. l, 3, 5, and 6, and consists of a frame u, formed to contain, in suitable bearings for rotation, a bevel-pinion c', set upon a hollow sleeve o2, journaled in said bearings, and a lateral driving-shaft es, having acorresponding bevel-pinion (miter-gear) 'U4 in constant mesh with the pinion v', and a driving-pulley 05, the latter upon a terminal projection of the shaft beyond the frame m.

'The frame u is secured to pipes or bars u',

porting-frame of the machine and held by set-screws, thus bringing the hollow sleeve @2 in front of the machine in the projected vertical axis of the well. The drill sito be rotated passes through the sleeve fu2 and is suitably engaged therewith in any convenient manner for its due rotation. The driving-shaft r3 is rotated by a direct belt connection between its pulley v5 and a corresponding pulley p1 on the main shaft f, the belt being put on or offas required. During operation the rotation of the drill may be instantly stopped or started by-engagem'ent or disengagement of the main pulley of the main shaft through manipulation of the clutch devices, and the same is true of any other of the operative mechanisms. Vhen not in use, the frame u is taken ed or detached at one side and turned up vertically upon its opposite supporting-bar u as a hinge.

'lhemodied arrangement of mechanisms upon the frame in Fig. 5 will serve to illustrate the freedom with which such changes may be made as a functional advantage of the frame structure and shaft supports. Such a unit is used, for example, in a mine or at the bottom of a shaft and driven from a motoratthe earth surface. Ordinarily the motor-for example, a gasolene-engine-may rest upon the rear extensions of the sills a' a2, driving a shaft w', as shown in Fig. l.

` I claim and desire to secure by Letters Patent of the United Statesl. In a well-sinking apparatus a rectangular supporting-frame composed of an upper and lower series of horizontal tubular sills connected by vertical tubular uprights united thereto by pipe-fittings and with corneruprights extended above the uppermost hori- Zontal sills, in combination with the derrick consisting of two side peces,one at each side of the frame and provided with fittings extending in the direction of the length of the said side pieces and provided with terminal studs, said forward-extended corner-uprights having sockets to receive said studs when the derrick is in its elevated position, and said fittings pivotally mounted to said forward uprights substantially as set forth.

2. In a well-sinking apparatus, a rectangular tubular supporting-frame substantially as described and including corner-uprights, in combination with derrick composed of two side members converging upward -and having fittings at their lower ends and forming longitudinal extensions of said ends one of said side pieces pivotally mounted to each of the corner-uprights of the main frame and said fittings having terminal studs to fit sockets in the upper extremities of the front uprights, when the derrick is in elevated position, a Walking-beam having one end pivotally connect-ed to the extended portions of the rear corner-uprights and extending forward between the extended portions of the front uprights substantially as set forth.

3. In a well-sinking apparatus of the character indicated, the combination with a frame composed of horizontal spaced metallic tubes and vmeans uniting them at the ends, and tubular corner-posts, of a shaft-support `consisting essentially of a triangular block on each of a pair of tubes and having a journalbearing-at the apex and perpendicular to the plane 0f the triangle, a groove at the base and in the plane of the triangle and one or more correspondingly-grooved caps removably united thereto with screws or bolts to constitute a clamp connection for the shaftsupport upon a tubular sill or upright of a frame, substantially as set forth.

4. The combination with a main frame having sockets at the front, of a removable revolving-head device embodying aframe containing the revolving head, said last-named frame fixed to bars or tubes adapted to telescope into said sockets of the main-frame,`

a driving-shaft engaging the revolving head by bevel-gearing and clamping-caps adapted to secure the device removably upon sills or extensions of the main supporting-frame of the well-sinking apparatus, substantially as set forth.

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