DIGGING APPARATUS.
Application led October 18, 192,6. Serial No. 142,311.
The present invention relates to diggin orvexcavating apparatus or tools employe for digging post-holes and the like. The invention consists of certain improvements inapparatus or tools of this kind and the chief object of the invention is to provide an eiiicient tool which is simple in construction and operation and which may be used either for manual or power operation.
lo The improved tool in one form is in the nature of an auger having a vbucket at each .side and these buckets are providedlat their lower and vclosed end with lips or bits so arranged that the earthfdisplaced thereby is taken into the buckets and when the tool is withdrawn from the hole, the buckets can be readily emptied. Provision is made in one 'form of the invention for dumping these buckets which in this case are pivoted 2o and have associated therewith means for tiltingthe buckets to discharge the contents therefrom.' .1
The improved tool has a shank carrying a head and said shank maybe extended to allow holes or excavations of varying depth to be dug andwhich shank may be operated by hand or power as desired. The head of the tool consists of la supporting plate or member secured to the shank and at each side of said member, a bucket is mounted. In one-form of the invention, the buckets are secured against any independent movement.- This form is useful for digging comparatively .sm'all and 4shallow holes and this tool must 'be bodily tilted at various angles to empty the buckets. In another and preferred form, the buckets are pivotally mounted on the supporting member andl means, comprising an operating lever, a pair 4o of eccentrics l.and a connecting .link 'or links, are provided for turning the buckets on their pivots so' as t'o empty them.l
It frequent-l occurs that holes'or other excavations o -comparatively great depth are required to be dug and in ansandy or loose earth and so to avoidk caving in of the sides of the excavation, a lining, in sections is dropped intothe hole during the digging operation. To accomplish the desiredv re.- sults, it is proposed to employ a follower or ring which is looselyengaged by the head or auger part of the tool. This ring follows the auger and clears the wa for the tubular lining sections which are opped into the u hole around the-tool as it adyances into the earth. The tool musi b9 Withdrawn 4from with the shank, as shown in Figure 1.
the hole to empty thel buckets and with a power driven igger,the'buckets may be automatically operated.
lIn order that the invention may be more clearly understood, an embodiment of the same will be hereinafter fully described and illustrated in the accompanying drawings whereinc Figure 1 is a side elevation 'of the im- 65 provedtool in the position for operation; Figure 2 is a lan view of the ring or follower employe in conjunction with the* improved tool; i
Figure 3 is a s follower;
Figure 4 is a side elevation of the improved tool partly in section, and
\Figure 5 is a side elevation of the improved tool partly in section showinof the side of the tool opposite to the side s own in Figure 4. l Figure 6 is a top-plan view of the im. proved tool, and Figure 7 isa cross sectional View of the improved tool.
Referring to the said drawings, the tool shown thereinis composed of a head 1 in the form of a plate having secured thereto the operating shank 2 which latter is shown V as being'broken away. Obviously the shank ide elevation of said ring or lmay be of any length according to the depth of the hole to be dug or if desired said shank may. be composed of sections with means for joining the same together to obtain a shank of lthe required length. At each side of said plate 1, buckets are mounted ony a common pivot 3 and said buckets are respectively designatedby the- numerals 4 and 5. These buckets turn on thepivot 3 so as to assumel opposite angular positions wherein the contents of the buckets may be dumped therefrom. It will be noted during the digging operation, the buckets are -in alignment Means are provided for operating the buck- 150 ets and these means comprise a pair of eccen- -tr1cs 6 and '7 which are mounted on a comi mon pivot Sand said means also includes an operating lever 9 which is secured to the eccentric 6. The eccentrica 6 and 7 are -fxedly mounted on the pivot 8 in such a manner that operation of the lever 9 will eft'ect a partial turning of both eccentrics with a cam-like movement. Transmission means are employed to connect the bucket 4 with the eccentric 6 and such means comprises the slotted link 10 which is pivoted at 11 on the rsf bucket 4, the slot 12 of the link 10 engaging the pin 13 mounted on the eccentric 6. 1t will be understood that the operation of the lever in a downward movementy will tilt the bucket 4 into the angular position shown in Figure 4 and when the lever is in the raised position, up against the stop 14, the bucket t'is held in its closed position for operation.
The companion bucket 5, on the other side of the head, is operated directly by the eccentric 7, as shown in Figure 5. The turning of both ofthe eccentrics in the direction of the indicating arrow, causes the eccentric 7 to bear against the pin 15 of the bucket 5 and thus cause this bucket to assume the angular or dumping position. lfVhen the eccenti'ics are turned in the reverse direction, the eccentric 7 bears against the sides of the bucket to close the same.
It will be seen that in the above arrange- Iinent, the buckets are operated directly and indirectly by the operating lever and it will be understood that this lever may be operated by hand or automatically, depending whether or not the tool is operated manually or by power.
Both of the buckets aie provided with removable lips or bits 16 in the form of plates which are bolted to the bottom of the buckets and which bits are easily replaced and may be composed of tempered steel and formed to meet the different requirements which n iust be met when the earth is hard and rocky, or soft and sandy.
ln cases where a comparatively small and shallow hole is to be dug in fairly hard soil the tool as described will alone answer the purpose, but in such cases4 where a deeper hole or excavation is to be dug, or if the hole is to be dug in sandy soil, which is apt to cave in, the hole is reinforced with a lining as shown in' Figure 1. In this case,`the follower or ring 17 is employed. This ring may be composed of a cheaper grade of metal and is not required to be machined, therefore, a rough casting may be used. This ring is located around the 'head of the. tool and is loosely engaged thereby by means of lugs 18 so that said ring 17 will turn with the tool When the latter is turned in the directionindicated by the arrows, and when the tool is turned in the reverse direction, said lugs are disengaged. Sei-rations 19 are formed on the lower edge of the ring 17 so that it will' assist the bits 16 in cutting its way into the earth. The ring 17 remains in the hole and forms part'of the lining. Additional lining sections 20 are dropped into the hole around the tool as the same advances, down into the earth and by this means a retaining wall is lprovided for the hole. In the ,operation ofthe improved tool, the buckets are held in the position of alignment with the shank during the digging operation and the earth which is displaced by the bits, is received in the buckets and when the latter are full, the tool is lifted out of the hole and the buckets are then brought to their a'ngular or dumping position by operation of the operating lever. To simplify the construction, the buckets are brought back to their aligned position by operation of the lever but obviously a spring or springs may be employed to effect the self-return of the buckets to their aligned position.
Various modifications may be made in the construction and arrangement of the iniproved tool heieinbefore described and various ways of employing the same may be adopted therefore it is to be understood that any modication coming fairly within the terms of the appended claims shall be covered thereby.
l claim- 1. An excavating tool having a head with a shank extending therefrom, a pair of buckets pivotally mounted on opposite sides of said head so as to permit a tilting movement of said buckets parallel to each other and means for turning said buckets on their pivot whereby the contents of said buckets are discharged.
