Description
5~
BA~::KGROUNp OF_THE INVENT ON
As shown in Figure 3 of United States Patent No. 2,403,002, most drilling machines are comparatively large and generally mounted on large vehicles. Yet often there are requirements to obtain earth core samples during earth and soil testing operations in places where the larger vehicle mounted drilling machines may not be conveniently used. In these difFicult piaces and in all places, including underwater locations, this principal supporting struc-ture, when equipped in various embodiments creates a portable machine which is conveniently used to obtain earth core samples wherever the earth and soil testing is to be undertaken.
The extreme portability centers on the use of a hydraulic or pneumatic cylinder as the main structural component of the principal supporting structure, and also centers on keeping in a separate power pack many of the hydraulic or pneumatic components, which then may be remotely located from the core drilling locations. For example, the power pack may be kept above the waterls surface, while the principal supporting structure, centering on either the hydraulic or pneumatic cylinder, is conveniently manipulated at the underwater site, where the earth core samples are being taken. The initiai power pack energy source is gasoline or diesel oil for engines, or electricity for electrical motors.
SUMMARY OF THE INVENTION
During earth and soil testing, earth core samples are readily under-taken in all locations and especially in otherwise inaccessible locations, such as underwater locations, under structure with limited overhead clearance, on steep grades, in remote areas, etc. where larger equipment, often mounted on vehicles, is not usable. The samples are taken by using a principal supporting structure, which is portable and centers on the use of either a hydraulic or pneumatic cylinder as ehe principal upstanding structure, of a portable machine.
Also many of the hydraulic or pneumatic components are kept in a power pack which is of~en remotely located from the principal supporting structure, especially in underwater operations where the power pack remains above the water.
In one embodiment the principal supporting structure is essentially the hydraulic cylinder, a piston rod extendable beyond the hydraulic cylinder to a distance almost equal to its length, force transmitting tie rods secured to piston ~ 5~
rod end and extended back to the hydraulic cylinder and passing through guides secured to the cylinder~ an elon~ated guide member secured to the cylinder exterior, and a sleeve slidable up and down the hydraulic cylinder having a follower to slide along the elongated guide, when the sleeve is secured to the force transmitting tie rods as they move with the piston. To this principal supporting structure a removable base is added, when necessary, having radial extending legs terminating in receiving portions equipped with earth penetrating stakes drivable through the receiving portions.
On this slidable sleeve a hydraulic driving power unit sub-assembly is mounted, comprising a driving hydraulic motor and its attachment accessories to secure and to rotate a hollow core digging auger, and to secure and to rotate a capstan. The capstan receives and powers a rope passing over the sheaves of a transverse header box, which is mounted on the end of the piston rod. The rope at one end is secured to a calibrated hammer used in preparing a core sample and at its other end, after passing around the capstan at least once, is guided by an operator. The operator by adjusting the height of the piston rod equipped with the transverse header bo>~ and operating the capstan conveniently handles this calibrated hammer and other equipment during its positioning over the location where the earth core samples are being taken.
Preferat2ly, a hydraulic control sub-assembly is secured to the elongated guide member of the hydraulic cylinder in a position clear of the travel of the sleeve and at a height conveniently manipulated by an operator. it includes multiple valves to direct hydraulic liquid to the hydraulic cylinder to extend or to retract the piston and correspondingly move the transverse header, the~tie rods, and the sleeve.
To unburden the operator at the immediate location o~ taking the earth core samples, and especially ln reference to underwater operations, the hydraulic power source and distribution sub-assembly is arranged for remote operation. A hydraulic pump, a motor to drive the hydraulic pump and a hydraulic tank,- are secured together in a conveniently handled power pack for remote placement. Then a selected sub-assembly of hoses and fittings are used to conduct the hydraulic liquid to and from the often remotely located power pack, during the distribution of the hydraulic liquid via the hydraulic control sub-assembly to the hydraulic cylinder sub-assembly and to the hydraulic driving power unit sub-assembly. By using this principal supporting structure and the resulting portable machine, either hydraulic or pneumatic, earth core samples are taken during soil testing operations, often occurring many times in what before seemed to be inacessible locations for carrying on convenient and efficient earth and soil testing operations. The initial power pack energy source is gasoline or diesel oil for engines3 or electricity for electrical motors.

DESCRIPTION OF THE INVENTION
InFigures 1 through 4, a preferred embodiment is illustrated of a principal supporting structure 10 for a portable machine 129 used, when fully equipped, in taking earth core samples during earth or soil testing operations.
Figure 4 schematically indicates how both hydraulic and pneumatic Fluid systems are utilized, dotted lines indicating a location of a compressed air tank 14, and a fluid line change 16, and the solid lines indicating the hydraulic oil system.
Principal Upstanding Supportinq Structure and its Grou_d SupE~rt As illustrated in Figures 1, 2 and 3, the principal upstanding support-ing structure 10 of the earth core sample taking portable machine 12 is essenti-ally a fluid cylinder-piston sub-assembly 20, either hydraulic or pneumatic, comprising a fluid cylinder 22, serving as the principal upstanding stationary body 22, of this portable machine 12; and a piston 24 with its plston rod 26, serving as the principal upstanding extendable body 28 of this portable machine 12. During most earth drilling and earth core sampling operations, this principal upstanding supporting structure 10 is supplernented by a removable base sub-assembly 30, serving as its ground support. It has four spaced radiaily extending legs 32 extending outwardly from a center receiver 3~, which fits around the ~luid cylinder 22, and is secured thereto by an insertable pin fastener 36, in a choice of two positions, lB0 degrees apart. The radially _~_ extending legs 32, at three locations, are held together by braces 38. Also these legs 32 terminate in vertical cylindrical receivers 407 through which earth penetrating stakes 42 are driven, to transfer the reactive torque forces to the earth during drilling operations.
F lu-id Drlvin~Power Un_t Sub-As ~y~ - unting As illustrated in Figures 1 and 3, a fluid driving power unit sub-assembly 46 has a frame 48 secured to partial sleeve 50, which slides up and down the exterior of the principal stationary body 22, i. e. the fluid cylinder 22.
A fluid motor S2 and its coupling 54 is mounted on frame 48. Also a capstan 56 and right angle drive unit 58 are mounted on the frame~48. The earth core sampling drilling auger sections 60 are alternately secured to the coupling 54 of the fluid motor 52 and to each other as the drilling operations are undertaken.
Force Transmitting Rods Attached Between Partial 51eeve 51idable on the Fluid Cvlinder and the Upward Extendable End of the Piston Rod As illustrated in Figures 1, 2 and 3, the partial sleeve 50, to which the frame 48 is attached, is also secured to two force transmitting rods 62 at their bottom. They, 62, in turn are secured at their tops to a transverse plate 64 secured to the upward extendable end of the piston rod 26. The extending and retracting movements oF the piston rod 26 and its piston 24, i. e. the extend-able body 28, therefore are also the upwardly and downwardly sliding movements of the partial sleeve 50 along the exterior of the fluid cylinder 22, and therefore along the exterior of the principal supporting structure 10. The partial sleeve 50 is guided and kept from turning relative to the fluid cylinder 22, by the elonga-ted guide member 66 which is secured to the fluid cylincler 22. As necessary, an end thrust is generated by the fluid cylinder-piston sub-assembly 20, through these force transmitting rods 62, during drilling operations. At other times the fluid driving power unit sub-assembly 46 is positioned at other convenient locations along the fluid cylinder 22 by using the fluid cylinder-piston sub-assembly 20 and these force transmit~ing rods 62.
A Transverse Header Box llaving Sheaves Mounted at Each End and in Turn Mounted on the ~ransverse Plate Secured on the Upward Extendable End of the Piston Rod to Receive a Rope Utilized V\tith the Capstan and Sheaves to Handle a Calibrated Core Samplin~Hammer, etc. _ _ _ As illustrated in Figures 1 and 27 at the top of this portable machine 12~ there is a transverse header box 70 secured to the transverse plate 64 fastened in turn to the extendable end of the piston rod 26. At each of its ends 5~
sheaves 72 are rotatably mounted. A rope 74 is guided over the sheaves 72 and down one side of the principal supporting structure 10, to be wrapped around the capstan 56 and beyond for hand control by an operator, as shown in Figure 2.
The other end of the rope 74 is tied to a lifting hook 76. it in turn is used to attach various core drilling accessories, such as the core sampling rod components 80, ` 82 .
Fluid Control Sub-Assembly to Control Amount of Fluid Flowing and Where the Fluid Flows to Either or to Both the Fluid Motor and Fluid Cylinder-Piston Sub-Assembl v . . . _ ~ _ . . _ _ . . .
As illustrated in Figures 1 and 4, there is a preferred embodiment of a fluid control sub-assembly 86 mounted at a convenient height, about waist high, on the principal supporting structure 10 of this portable earth core sampling machine 12. By moving respective valve handles 88, 90, 92, 94, respective flow regulation and shut off valves 96, 98, and flow direction valves 100, 102, are actuated to gain the fluid operational forces desired during the various operations. Optionally only one flow regulation valve at another loca-tion is used. Also optionally the fluid flow shut off is undertaken at another location.
Referring to the schematic view of Figure 4, a principal power source 104, which is either an electric motor, or gasoline or diesel engine is used to drive a pump 106 or an air compressor 106, via a drive belt 108. When a hydraulic oil system is used, then a reservoir 110 is included in the fluid line system 112. When a pneumatic system is used, then a compressed air tank 114 is included in the fluid line system 112, the lines 116 and valves etc. being sized and designed accordingly to meet the dif-Ferent -Fluid requirements.
The raising and lowering of extendable body 28, i. e. the piston-piston rod combination 28, is undertaken, when valve 96 is opened and set at a selected flow rate upon movement of valve handle 88, and also valve handle 92 is moved to set flow directional valve 103 to direct the fluid, either to raise or to lower this extendable body 28, the lowering being illustrated in Figure 4.
The rotation in either direction of the capstan 56, is undertaken, when valve 98 is opened and set at a selected flow rate upon movement of valve handle 90, and also valve handle 94 is moved to set flow directional valve 102 to direct the fluid, either to rotate the capstan 56 in one rotative direction or the other rotative direction, i.e. clockwise or counterclockwise, the counterclockwise rotation being illustrated in Figure 4. The rotative movement of the capstan 56 is utilized to create a lifting force, via the rope 7~, as it is wrapped around the capstan and guided over the sheaves 72, to its lifting hook 76, secured, for example, to the core sampling hammer 78, as illustrated in Figures 2 and 4.
Remote Location Arrangement of Selected Components of the Fluid Power and Control System ~
As illustrated in Figures 1 and 29 several of the components illustra-ted in Figure 4 are arranged in a power pack 118 for remote positioning, operation, and handling, being kept for example, on the bed 120 o~ a pickup truck 122. For example, the power source 104, such as a gasoline engine 104, the hydraulic oil pump 106, and the hydraulic oil reservoir 110 with some of the fluid lines 116, are arranged as a power pacl< 118, on a conveniently handled supporting platform 1~4.
Summary of PrincipaJ Advantages The utili7ation, in this portable earth core sampling machine 12, of a principal supporting structure 10, comprising essentially a principal upstand-ing stationary body 22, which is a hydraulic cylinder 22, and an upstanding extendable body 28, which is a piston-piston rod combination, substantially reduces the overall weight of the core sampling machine 12, or drilling rig 12.
To further enhance the portability and handling of this drilling rig 12, the power pack 118 is arranged for remote placement~ handling, storage, transport, and positioning, thereby giving an operator hand and arm positioning, transport, and control capabilities, related only to the principal supporting structure 10 and its various accessories used at an immediate drilling and earth core sampling location.
Particularly, this overall arrangement makes it possible to carry the principal supporting structure 10 into locations not otherwise accessible to other earth core sampling machines, such as bog areas or low clearance areas.
Moreover, it is possible to take the principal supporting structure 10 and its immediate accessories below the surface of water to successfully carry out earth core sampling under water. All these operations, above and below water, are undertaken very conveniently in these new areas and in all areas, using conventional methods in taking earth core samples.
Altl ough the portability, of the illustrated earth core sampling machine 12, centering on its principal supporting structure 10, is outstanding, it is also to be considered and realized that the machine 12 in other embodimen~s7 not illustrated is larger. The principal upstanding stationary body 2~, i. e.
the fluid cylinder 22, in other embodiments is much larger and is a functional derrick. It is mounted on a vehicle or erected at a job site. Moreover, being available in many sizes, the principal supporting structure 10, equipped with suitable specified drilling accessories, is used for drilling through soil and rock, gaining all of the advantages of utilizing a fluid cylinder 22, as the principal upstanding stationary body 22.
BA~::KGROUNp OF_THE INVENT ON
As shown in Figure 3 of United States Patent No. 2,403,002, most drilling machines are comparatively large and generally mounted on large vehicles. Yet often there are requirements to obtain earth core samples during earth and soil testing operations in places where the larger vehicle mounted drilling machines may not be conveniently used. In these difFicult piaces and in all places, including underwater locations, this principal supporting struc-ture, when equipped in various embodiments creates a portable machine which is conveniently used to obtain earth core samples wherever the earth and soil testing is to be undertaken.
The extreme portability centers on the use of a hydraulic or pneumatic cylinder as the main structural component of the principal supporting structure, and also centers on keeping in a separate power pack many of the hydraulic or pneumatic components, which then may be remotely located from the core drilling locations. For example, the power pack may be kept above the waterls surface, while the principal supporting structure, centering on either the hydraulic or pneumatic cylinder, is conveniently manipulated at the underwater site, where the earth core samples are being taken. The initiai power pack energy source is gasoline or diesel oil for engines, or electricity for electrical motors.
SUMMARY OF THE INVENTION
During earth and soil testing, earth core samples are readily under-taken in all locations and especially in otherwise inaccessible locations, such as underwater locations, under structure with limited overhead clearance, on steep grades, in remote areas, etc. where larger equipment, often mounted on vehicles, is not usable. The samples are taken by using a principal supporting structure, which is portable and centers on the use of either a hydraulic or pneumatic cylinder as ehe principal upstanding structure, of a portable machine.
Also many of the hydraulic or pneumatic components are kept in a power pack which is of~en remotely located from the principal supporting structure, especially in underwater operations where the power pack remains above the water.

To this principal supporting structure a removable base is added, when necessary, having radial extending legs terminating in receiving portions equipped with earth penetrating stakes drivable through the receiving portions.
On this slidable sleeve a hydraulic driving power unit sub-assembly is mounted, comprising a driving hydraulic motor and its attachment accessories to secure and to rotate a hollow core digging auger, and to secure and to rotate a capstan. The capstan receives and powers a rope passing over the sheaves of a transverse header box, which is mounted on the end of the piston rod. The rope at one end is secured to a calibrated hammer used in preparing a core sample and at its other end, after passing around the capstan at least once, is guided by an operator. The operator by adjusting the height of the piston rod equipped with the transverse header bo>~ and operating the capstan conveniently handles this calibrated hammer and other equipment during its positioning over the location where the earth core samples are being taken.
Preferat2ly, a hydraulic control sub-assembly is secured to the elongated guide member of the hydraulic cylinder in a position clear of the travel of the sleeve and at a height conveniently manipulated by an operator. it includes multiple valves to direct hydraulic liquid to the hydraulic cylinder to extend or to retract the piston and correspondingly move the transverse header, the~tie rods, and the sleeve.
To unburden the operator at the immediate location o~ taking the earth core samples, and especially ln reference to underwater operations, the hydraulic power source and distribution sub-assembly is arranged for remote operation. A hydraulic pump, a motor to drive the hydraulic pump and a hydraulic tank,- are secured together in a conveniently handled power pack for remote placement. Then a selected sub-assembly of hoses and fittings are used to conduct the hydraulic liquid to and from the often remotely located power pack, during the distribution of the hydraulic liquid via the hydraulic control sub-assembly to the hydraulic cylinder sub-assembly and to the hydraulic driving power unit sub-assembly. By using this principal supporting structure and the resulting portable machine, either hydraulic or pneumatic, earth core samples are taken during soil testing operations, often occurring many times in what before seemed to be inacessible locations for carrying on convenient and efficient earth and soil testing operations.

DESCRIPTION OF THE INVENTION
InFigures 1 through 4, a preferred embodiment is illustrated of a principal supporting structure 10 for a portable machine 129 used, when fully equipped, in taking earth core samples during earth or soil testing operations.
Figure 4 schematically indicates how both hydraulic and pneumatic Fluid systems are utilized, dotted lines indicating a location of a compressed air tank 14, and a fluid line change 16, and the solid lines indicating the hydraulic oil system.
Principal Upstanding Supportinq Structure and its Grou_d SupE~rt As illustrated in Figures 1, 2 and 3, the principal upstanding support-ing structure 10 of the earth core sample taking portable machine 12 is essenti-ally a fluid cylinder-piston sub-assembly 20, either hydraulic or pneumatic, comprising a fluid cylinder 22, serving as the principal upstanding stationary body 22, of this portable machine 12; and a piston 24 with its plston rod 26, serving as the principal upstanding extendable body 28 of this portable machine 12. During most earth drilling and earth core sampling operations, this principal upstanding supporting structure 10 is supplernented by a removable base sub-assembly 30, serving as its ground support. It has four spaced radiaily extending legs 32 extending outwardly from a center receiver 3~, which fits around the ~luid cylinder 22, and is secured thereto by an insertable pin fastener 36, in a choice of two positions, lB0 degrees apart. The radially _~_ extending legs 32, at three locations, are held together by braces 38. Also these legs 32 terminate in vertical cylindrical receivers 407 through which earth penetrating stakes 42 are driven, to transfer the reactive torque forces to the earth during drilling operations.
F lu-id Drlvin~Power Un_t Sub-As ~y~ - unting As illustrated in Figures 1 and 3, a fluid driving power unit sub-assembly 46 has a frame 48 secured to partial sleeve 50, which slides up and down the exterior of the principal stationary body 22, i. e. the fluid cylinder 22.
A fluid motor S2 and its coupling 54 is mounted on frame 48. Also a capstan 56 and right angle drive unit 58 are mounted on the frame~48. The earth core sampling drilling auger sections 60 are alternately secured to the coupling 54 of the fluid motor 52 and to each other as the drilling operations are undertaken.
Force Transmitting Rods Attached Between Partial 51eeve 51idable on the Fluid Cvlinder and the Upward Extendable End of the Piston Rod As illustrated in Figures 1, 2 and 3, the partial sleeve 50, to which the frame 48 is attached, is also secured to two force transmitting rods 62 at their bottom. They, 62, in turn are secured at their tops to a transverse plate 64 secured to the upward extendable end of the piston rod 26. The extending and retracting movements oF the piston rod 26 and its piston 24, i. e. the extend-able body 28, therefore are also the upwardly and downwardly sliding movements of the partial sleeve 50 along the exterior of the fluid cylinder 22, and therefore along the exterior of the principal supporting structure 10. The partial sleeve 50 is guided and kept from turning relative to the fluid cylinder 22, by the elonga-ted guide member 66 which is secured to the fluid cylincler 22. As necessary, an end thrust is generated by the fluid cylinder-piston sub-assembly 20, through these force transmitting rods 62, during drilling operations. At other times the fluid driving power unit sub-assembly 46 is positioned at other convenient locations along the fluid cylinder 22 by using the fluid cylinder-piston sub-assembly 20 and these force transmit~ing rods 62.
A Transverse Header Box llaving Sheaves Mounted at Each End and in Turn Mounted on the ~ransverse Plate Secured on the Upward Extendable End of the Piston Rod to Receive a Rope Utilized V\tith the Capstan and Sheaves to Handle a Calibrated Core Samplin~Hammer, etc. _ _ _ As illustrated in Figures 1 and 27 at the top of this portable machine 12~ there is a transverse header box 70 secured to the transverse plate 64 fastened in turn to the extendable end of the piston rod 26. At each of its ends 5~
sheaves 72 are rotatably mounted. A rope 74 is guided over the sheaves 72 and down one side of the principal supporting structure 10, to be wrapped around the capstan 56 and beyond for hand control by an operator, as shown in Figure 2.
The other end of the rope 74 is tied to a lifting hook 76. it in turn is used to attach various core drilling accessories, such as the core sampling rod components 80, ` 82 .
Fluid Control Sub-Assembly to Control Amount of Fluid Flowing and Where the Fluid Flows to Either or to Both the Fluid Motor and Fluid Cylinder-Piston Sub-Assembl v . . . _ ~ _ . . _ _ . . .
As illustrated in Figures 1 and 4, there is a preferred embodiment of a fluid control sub-assembly 86 mounted at a convenient height, about waist high, on the principal supporting structure 10 of this portable earth core sampling machine 12. By moving respective valve handles 88, 90, 92, 94, respective flow regulation and shut off valves 96, 98, and flow direction valves 100, 102, are actuated to gain the fluid operational forces desired during the various operations. Optionally only one flow regulation valve at another loca-tion is used. Also optionally the fluid flow shut off is undertaken at another location.
Referring to the schematic view of Figure 4, a principal power source 104, which is either an electric motor, or gasoline or diesel engine is used to drive a pump 106 or an air compressor 106, via a drive belt 108. When a hydraulic oil system is used, then a reservoir 110 is included in the fluid line system 112. When a pneumatic system is used, then a compressed air tank 114 is included in the fluid line system 112, the lines 116 and valves etc. being sized and designed accordingly to meet the dif-Ferent -Fluid requirements.
The raising and lowering of extendable body 28, i. e. the piston-piston rod combination 28, is undertaken, when valve 96 is opened and set at a selected flow rate upon movement of valve handle 88, and also valve handle 92 is moved to set flow directional valve 103 to direct the fluid, either to raise or to lower this extendable body 28, the lowering being illustrated in Figure 4.
The rotation in either direction of the capstan 56, is undertaken, when valve 98 is opened and set at a selected flow rate upon movement of valve handle 90, and also valve handle 94 is moved to set flow directional valve 102 to direct the fluid, either to rotate the capstan 56 in one rotative direction or the other rotative direction, i.e. clockwise or counterclockwise, the counterclockwise rotation being illustrated in Figure 4. The rotative movement of the capstan 56 is utilized to create a lifting force, via the rope 7~, as it is wrapped around the capstan and guided over the sheaves 72, to its lifting hook 76, secured, for example, to the core sampling hammer 78, as illustrated in Figures 2 and 4.
Remote Location Arrangement of Selected Components of the Fluid Power and Control System ~
As illustrated in Figures 1 and 29 several of the components illustra-ted in Figure 4 are arranged in a power pack 118 for remote positioning, operation, and handling, being kept for example, on the bed 120 o~ a pickup truck 122. For example, the power source 104, such as a gasoline engine 104, the hydraulic oil pump 106, and the hydraulic oil reservoir 110 with some of the fluid lines 116, are arranged as a power pacl< 118, on a conveniently handled supporting platform 1~4.
Summary of PrincipaJ Advantages The utili7ation, in this portable earth core sampling machine 12, of a principal supporting structure 10, comprising essentially a principal upstand-ing stationary body 22, which is a hydraulic cylinder 22, and an upstanding extendable body 28, which is a piston-piston rod combination, substantially reduces the overall weight of the core sampling machine 12, or drilling rig 12.
To further enhance the portability and handling of this drilling rig 12, the power pack 118 is arranged for remote placement~ handling, storage, transport, and positioning, thereby giving an operator hand and arm positioning, transport, and control capabilities, related only to the principal supporting structure 10 and its various accessories used at an immediate drilling and earth core sampling location.
Particularly, this overall arrangement makes it possible to carry the principal supporting structure 10 into locations not otherwise accessible to other earth core sampling machines, such as bog areas or low clearance areas.
Moreover, it is possible to take the principal supporting structure 10 and its immediate accessories below the surface of water to successfully carry out earth core sampling under water. All these operations, above and below water, are undertaken very conveniently in these new areas and in all areas, using conventional methods in taking earth core samples.
Altl ough the portability, of the illustrated earth core sampling machine 12, centering on its principal supporting structure 10, is outstanding, it is also to be considered and realized that the machine 12 in other embodimen~s7 not illustrated is larger. The principal upstanding stationary body 2~, i. e.
the fluid cylinder 22, in other embodiments is much larger and is a functional derrick. It is mounted on a vehicle or erected at a job site. Moreover, being available in many sizes, the principal supporting structure 10, equipped with suitable specified drilling accessories, is used for drilling through soil and rock, gaining all of the advantages of utilizing a fluid cylinder 22, as the principal upstanding stationary body 22.
