IMPROVEMENT IN EARTH-AUGERS.

, Specification forming part of Letters Patent No. 184,257, dated November 14, 1876; application filed April l0, 1876.

To all whom t may concern:

Be it known that I, ALFRED W. MORGAN, of Indianapolis, county of Marion, State of Indiana, have invented a new and useful Well-Boring Apparatus for loosening and removing earth from wells, of which the following is a description, reference being had to the accompanying drawings.

My invention consists of the construction, arrangement, and operation of devices, as hereinafter described and claimed, whereby I am, first, enabled to bore a hole or well of any desired size in diameter, and to any desired depth; and, second, to remove the loosened earth from the Well by means of an elevator, so arranged as to travel around in the well and hold its relative position at all times to the boring-shaft, and at the same time to elevate the loosened earth to the top of the well, where it is deposited either on the ground or into Suitable conveyances for future disposal. In the drawings, Figure 1 represents an ele.

The frame of my apparatus is of the usual construction, and consists of the sills A3, corner upright standards A, and cap A1. Secured to, and immediatelyr under the cap A, and extending out sidewise on each side, is the crossbeam lV, and to the outer ends thereof are secured the two guide-shafts B R', the lower ends of which are also secured to the sills A3; and on these guide-shafts R R is attached the slide or cross-head K, in the manner shown in Fig. l. 0n the under side of the cross-head K is secured the dan ge E, as shown. The an ge E forms part of the bevel-pinion El, and is connected thereto by the neck Y, the interior arrangement of which is shown in Fig. 3,

and will be hereafter described. The boringshaft B is vprovided at the upper end with a swivel curved head, B5, in such a manner as v to allow the curved head to adjust itself to the sweep C. The head B5 is forked, and has a sheave,'D1, at the upper end, and sheave D2 just above the pivot-joint. And at the rear end of the sweep O is attached an eyebolt, Z, to which is attached the end of the rope d, which passes over sheave D2, and then down to sheave D that is attached to the sweep, then up over the sheave D1, andis there made fast to the sweep at any convenient position. The design of the arrangement of rope and sheaves is to elevate the sweep when desired. The boring-slaftB extends downward through the square hole in the sheave BI that revolves in thecap A1 of the frame, and then through the set-collar B2 above the cross-head K; then through the cross-head K and stationary bevelwheel El E, and is then secured in the upper end of the coupling E4 by means of the bolt h, as shown in Figs. `1 and 4; and the extendedpart B4 of the shaft B is also coupled to the coupling E4, and is made of any length required; all of which will be hereafter more fully described.

Immediately under the cap Al of the frame is secured a cross bar or beam, W, and at each end thereof is secured the upright guide-rods RB', the lower ends of which are secured to the sills A3 of the frame in such a manner as to leave the guide-rods parallel. with each other.l On these guiderods is secured the cross-head K by anysnitable boxes, so that the cross-head is free tobe raised or lowered when required, by means of the angle-rods M and rope M. The angle-rod M is secured to the upper side of the cross-head K, and the rope M is secured to the upper angle thereof, and extends upward over a pulley (l not shown) in the cap A1; then the rope passes down and is secured to the drum L3, which is operated by means of the large pinion L2 on the drum L3, and the small pinion Ll on the crank-shaft L by the crank L4, in the usual manner.

The stationary bevel-pinion El is formed with a neck, Y, and a flange, E, above. The iiange E is secured to the under side of the crosshead K in a permanent manner. The flange E, neck Y, and pinion .El are. cast in about half-way through the coupling.

one piece, and formed hollow inside, and the boring-shaft B passes through it, and is supported in the middle of the pinion E1 by means of the sleeves S S. The sleeve S is formed with a ange, to prevent it from dropping down, and is also provided with a square hole, in which is the boring-rod B, and as the shaft B revolves it carries with it the sleeves S S', that revolve in the bore of the stationary casting that forms the ange E, neck Y, and pinion E1, as shown in Fig. 1, and more fully in Fig. 3. Immediately under the stationary bevel-pinion E1 the boring-shaft B is provided with a stud or arm, G, on which is journaled the chain or rope pulleys H H1 of the elevator.

The pulley H is of peculiar constructionthat is, the face of the pulley nearest to the shaft B is ccncaved, and has the small bevelpinion F either cast therein or otherwise secured to the pulley.

The object of forming the pulley H concaved is to allow the pulleys H H1 to operate on the shaft G as 'close to the boring-shaft B as possible, and to get the stationary wheel E1 large enough to give the required number' of revolutions to pinion F, as the pinion F and its attachments travel around the stationary pinion E1.

Immediately below the arm G of the shaft B the end of shaft B is secured in the coupling E4 by means of the bolt h. The shaftB being square fits into the square socket at the upper end of the coupling E4, and extends The lower part of the coupling E4 is formed with a square socket, one side of which is left open, and the sides EG at the open part are made to project outward, and are perforated with a keyway, x, in which is inserted the -key E5.

The upper end of the boring-shaft B4 is placed in the square socket of the coupling E4 between the projecting sides E3, and the upper end of the boring-shaft B4 is provided with a notch, in which the key E5 is driven when inserted in the keyway a: formed in the projecting sides E3, and thus secure the lower boring-shaft in a firm manner.

At the lower end of the boring-shaft B4 is secured the extension-bitted auger, formed of the plates N N1, and extension auger N3, and the auger-point N2, which will hereafter be described. Above the auger and secured to the shaft B4 is a clamp, E3, secured by means of a set-screw, E3, in any desired position. The elampE2 is also provided with a projection stud or shaft, O, on which revolves the lower elevator-pulleys H3 H4.

The elevator-pulleys H H1 H3 H4 are formed with notches cut at the proper places, to receive and guide the elevator-buckets J, which have proper lugs a a (shown in Fig. 7) at the sides near the top of the bucket, in which are clamped the wire ropes P or arranged to be attached to a chain of proper construction, and the lower lugsg of the buckets J also clasp the rope or chain to prevent the bucket from tilting or turning over.

The arrangement of the buckets on the rope or chain P, and the man nerin which they operate over the pulleysH H1 H3 H4-are clearly shown in Fig. 2, and here it will be seen that the buckets J as they commence to descend into the well, after leaving the top pulleys H H1, are carried back at an angle by the rope or chain P passing over the guide-pulleys w, which are attached to the earth-platform J in such a manner as to allow the earth to fall on the platform J', or into a bucketV attached thereto, and at the saine time to allow the buckets J to pass the platform` freely.

The upper shaft Gr of the pulleys H H1 is supported on the outside of the pulleys by the brace H3, and the earth-platform J is secured to the coupling E4 in the manner shown.

As the well becomes deeper and more boring-shaft is required, the chain or ropes P are uncoupled and an extra section of shaft is added between the shaft B4 and B by `nncans ot' extra couplings E4, the lower shaft B4 always remaining at the bottom, and the upper shaft B at the top. After the extra length of shaft has been introduced between shaft-s B and B4, then extra sections of chain or rope P, with extra buckets J, are added to the elevator, and, after being properly secured on the pulleys H H1 H3 H4, are made taut by means of the clamp E2 and'set-screw E3 on the lower shaft, or by means of the coupling E4, which allows the lower shaft to tighten the elevator chain or rope before it is secured in the coupling E4. Y

rIhe extension auger-bits N N1 N3 are se- .cured to the lower end of the boring-shaft B4,

and are constructed and arranged to operate as follows: The bit N is secured permanently to the hub N5 in a spiral manner with a pitch of nine inches, leaving the extreme diamondshaped pointy in its proper position to freely enter the ground; and to this bit, on the spiral above the point y, is attached the extended bit N1, which is also provided with a diamond-shaped point, y, and also with a flange, n, as shown in Fig. 5.

By this arrangement of the angers I am enabled to work under and remove large bowlders, that would otherwise retard the work of excavating the Well, and prevent any side draft to the auger. On the under side of the bits N N1, at their rear and highest edges, is secured an adjustable reamer, N3, the outer edge of which is turned up as at m', and made with a cutting-edge. The body of the reamer is provided with slots fr r, in which the bolts are secured that secure it to the bits N1 N. By this arrangement I am enabled to ream out the edges of the well, and thus relieve the main bits from the side friction, and also to `increase or diminish the size of the well.

Having thus described the manner in which my apparatus is constructed, I will now de scribe the manner in which it operates.

Power is applied to the sweep C, and, as the shafts B B4 revolve in the stationary bevelpinion E1, the auger-bits N2 N N1 and reamer N3 are allowed to enter the ground with any desired feed from the windlass L L3, and thus loosen upthe earth below the elevator-buckets. At the same time that the boring-shaft is revolving and the bits are loosening up the earth the arms Gr and O, with the elevatorpulleys H H1 H3 H4, are revolved around the stationary bevel-pinion E1, causing the pinion F, that is attached to the elevator-pulleys H H1, to revolve, thus causing the elevator chain or rope P, with its buckets J, to descend into the well on one side, and gather up the earth that is loosened by the bits N N1 N2 N3, and to bring up the earth in the buckets J as the elevator-buckets move up, and at the same 'time'the elevator chain and buckets travel around with the boring-shaft in the Well, thus keeping the buckets J working at the bottom of the well in the same position relative to the bits at all times, and the earth thus elevated is deposited on the dirt-platform J', as above, where it is conveyed into any kind of receptacle for its removal from the mouth of the well.
