Abstract
A sampling device is provided which, in one embodiment, includes a hinged body member. The hinged body member may be connected to a similarly configured non-movable body member, the body members forming a hollow sampling cylinder. The provision of a hinged body member provides easy access to the sample and therefor permits the user to remove the sample in an intact and consolidated form. A second embodiment provides for a pair of mutually pivotable body members to provide quick access to the sample core. In a further embodiment, a hollow sample cylinder may be disposed within the movable members to retain the sample.
The result is a sampling device which overcomes the limitations in the prior art by allowing the user to sample material to be sampled without disrupting or otherwise affecting the sampled material integrity.

Description
21~77~1 BANPI,ING 12BVICB
The present invention relates to a sampling device and more particularly, the present invention relates to an improved sampler which can be used in, for example, the soil sampling f ield .
Generally 8r~Ak;n~, samplLng devices have widespread utility in the ~ields of soil research, forestry, engineering, as well as the food sciences. In the traditional sampling e~
known in the art, one primary limitation is that the equipment requires considerable manual manipulation of the sample to remove it from the sampler. This is particularly unattractive when the user wishes to have an intact and c~n~ol ~ f7Ated sample. This is important where the user requires specific information with respect to density, moisture content, consistency, uniformity, among other important variables all of which depend upon the specific field of application for the sampling device. Different fields will, of course, require different information, but from an overall perspective, it is desirable to have an intact sample subsequent to sampling which does not require scraping or otherwise destroying the integrity of the sample in the sampler.
Turning to prior arrangements known in the sampling field, Ti~mann et al., in U.S. Patent No. 3,146,838, issued September 1, 1964, provides a sampling arrAn t which basically provides an explosive ejection to a sample receiving sleeve. This is as applied to the soil sampling field. Once the sampling sleeve has been injected into the soil, the user then may retract the cylindrical sleeve to obtain the sample of material. In this arrangement, the user must essentially destroy the integrity of the sampled material in order to remove it from the sampling sleeve.
As a variation on the soil sampling aLL~II; t.s, U.S.
Patent No. 3,162,256, issued to MPin~r~k~, issued December 22, 1964, provides a boring apparatus for removing undisturbed test samples of soil. In the M~;n~ apparatus, the user must rotate the apparatus in order for the same to penetrate the soil and therefore result in the collection of a sample. Similar to the above-mentioned arr~n~, L, thi6 arrangement is limited in that nlf~c~nt intervention is required in order to remove the sample from the sample container.
Prost, in U.S. Patent No. 4,633,957, issued January 6, 1987, provides a 80il plugger with a plug ej ector . In this aLLa..~ ~~ L, the apparatus includes an elongate tubular body having a cutting edge on one end. In order to insert the 10 apparatu~ into the soil, the user must apply force to the end portion of the apparatus and forcibly drive the apparatus into the 80il. In order to discharge the plug of soil, from the interior of the elongate tubular body, the apparatus is provided with a source of pressurized fluid to assist in ejection.
15 Although this aLLal~y nt is useful and may result in the sampling of an intact soil plug, it is clear that it is somewhat hindered by the fact that a pressurized fluid is required to remove the plug and therefore, the utility of this apparatus is somewhat limited when one is desirous of using the apparatus in 20 the field without the ~nl ' ances of a fluid pressure line or source of pressurized fluid therefore.
U.S. Patent No. 4,881,602, Hansen et al., issued November 21, 1989, provides a turf aerating tine. The coring 25 tine is provided with a penetrating end and has a core gripping configuration, for which the patentee provides ~ ~.us different embodiments. The core gripping configuration is adapted to retain a core of, for example, soil, however this aLLa~
although useful for the purpose of aerating the soil does not 30 address the needs of the user wishing to obtain a sample core in an intact consolidated form while at the same time having immediate and easy access to the core without having to disrupt the same. It would appear that the core simply remains in the end portion of this arrangement.
A further variation on this type of apparatus is illustrated in U.S. Patent No. 5,337,831, issued to Chopp, August 16, 1994.
~ 21477~1 The Chopp arrangement has a motorized system which provides a slidable cutting device for cutting a cup opening in a golf green. The ability for this apparatus to remove an intact and consolidated core is dependant on the properties of the soil and 5 is therefore not attributed to the apparatus.
Additional prior art which is relevant from an overall point of view to the apparatus of the preæent invention includes U. S .
Patent Nos. 3,480,093; 3,872,935; 3,915,245; 4,884,638;
g, 947, 938; 3, 047, 081 and 4, 930, 587 .
In view of what the prior art has proposed and the solutions the arrangement in the prior art have set forth, it is clear that there still exists a need for a simple mechanical arri3n~ for 15 sampling a material which does not result in the user having to disrupt the sample as collected and further a system is easily adapted to field use.
One feature of the present invention is to provide an 20 i _~ved sampling device for removing a sample of material in an efficient and expedited manner.
A further feature of the present invention is to provide a sampling device for removing a sample of a material to be 25 sampled, comprising: a frame means; a moveable sampling means for removing a sample of material, the sampling means including a first and a second body member together forming a hollow chamber adapted to receive a sample of material to be sampled, at least one of the body members being pivotally moveable relative to the 30 frame from a sampling position where the body members are positioned to form the hollow chamber to a sample releasing position where the moveable body member is pivoted away from the second body member; and means for releasibly urging the body members together.
~ 21~771~1 Where the apparatus iB applied to the 80il 5: ,1 ;n~ field, the apparatus advantageously permits the reception of an intact, contained and undisturbed soil sample for analysis.
A further significant feature attributed to the apparatus according to the present invention is the 5;gn;~icAnt time reduction required to obtain a high quality soil sample when compared to that previously provided by the prior art aSLally e-lts. This feature is attractive since a true representative sample is provided substantially all of the time and further that the sample releasing time is significantly reduced .
In one possible: '; ~ t, the apparatus will include a pivotally removable body member associated with the sampling chamber. By making use of a pivoting section on the sampling chamber, the result is that the user simply lifts the pivoting body away for its non-pivoting counterpart in order to gain access to a consolidated undisturbed sample. The sample can then be easily removed without having to disrupt or otherwise destroy the sample contained therein. This feature is particularly useful in the food industry where, for example, chee~e i~i sampled. Due to the texture and inherent consolidation of the cheese, the pivotally removable sampling body member permits ~auick and easy access to a core of cheese. Further, the consideration is important when rh~m;cAl representativeness of the sample is required as in pesticide s l; n~.
In a further possible : - ~ nt, the hollow sampling chamber may be ~ -sed of two pivotally moveable body members, if desired. In this arrangement, an attractive feature of the apparatus is the provision of an abutment on each one of the sleeves, which abutment is in contact with a pressure application member, such as a foot pedal forcibly urged against the individual sleeves or other such force applying means such as a hydraulic arrangement, a pressurized fluid aLLc~ilg -- t, ele~lL~ tic system, etc. It will be appreciated by those _ _ _ _ _ . ,, . , ,, . , _, ., . _ ... ...
skilled in the art that there are numerous possible: - '; r ts for the application of pressure to the pivoting body members.
Regarding the abutments, the same may be pivotally connected 5 to a frame of the apparatus in an off-centre relati~nch;r in order that the pivoting members have a proclivity to maintain a close relat;~n~h;r with one another. This is an attractive feature since under the application of ~r~s,,u.~, the pivoting members will, of course, be forcibly urged together which, in 10 turn, permits easy penetration of the members into the material to be sampled.
Where the apparatus is employed for soil extraction, the apparatus may include a hollow open-ended soil receptacle for 15 receiving a charge of soil therein. By making use of the pivoting members, the latter can act as a ground breaking system with the soil being received within the sleeve. Due to the fact that the pivoting members are moveable away from one another, the user may then simply effect movement and therefore be left with 20 a cfn~ol ;~lAted soil sample within a sleeve.
Where the material to be sampled is, for example, liquid, the apparatus can easily be modified to extract a liquid sample.
This may be achieved by making use of an evacuated hollow 25 cylinder or other such suitable means. A further feature of the present invention is to provide a soil sampling device for removing a sample of soil, the sampling device comprising: a frame; a moveable sampling means movably mounted to the frame, the sampling means comprising a first and a second body member, 30 the body members together forming a hollow chamber adapted to receive a sample of soil, the first and second body members being pivotally moveable relative to one another i~rom a sampling position wherein the members are positioned to form a hollow sample receiving chamber to a sample releasing position where the 35 moveable first and second members are pivoted away from one another; and means for releasibly urging the first and second body member towards one another.
21477~1 In addition to the aforementioned features of the present invention, numerous advantageous benefits flow from the design of the apparatus. These include, for example, the following: the design features a feature to quickly change the ~a~;r-n~inn~: of the 5 split s _ 1 in~ cylinder and related hardware; use of material such a6 aluminum, brass, stainless steel, composites or reinforced plastics contributes to a lightweight and corrosion resistant --h:~nl rm which is particularly useful for field use over long periods of time; and the applicability of the apparatus 10 to a host of technical fields.
A still further feature of the present invention is to provide a method of removing a sample of material from a material to be sampled, comprising: the steps of providing a hollow coring 15 body with a moveable body member; inserting the coring body into a material to be sampled; removing the coring apparatus; and moving the moveable body member to provide a sample core.
Having thus generally described the invention, reference 20 will now be made to the ~c~ ying drawings, illustrating preferred _a; Ls and in which:
Figure 1 is a perspective view of the apparatus according to one: ;r ~L of the present invention;
Figure 2 is an exploded view of the apparatus of Figure 1;
Figure 3 is a sectional view on line 3-3 of Figure 2;
3 0 Figure 4 is an alternative ' ~ t of Figure 3; and Figure 5 is a cross-sectional view of a receptacle for use with the present invention.
Referring now to Figures 1 and 2, shown i5 an embodiment o~
the present invention in which the overall s~mrlin~ apparatus is denoted by numeral 10.
2147~0~
In the example, the apparatus 10 includes an open frame 12, which frame includes a pair of spaced apart side walls 14 and 16 and a top wall 18 having an opening 20 therethrough, which opening is in ~ i ration with the interior of frame 12 . Two 5 spaced apart support members 22 and 24 are positioned in spaced relation, each connected to walls 14 and 16 of frame 12.
Positioned within frame 12 is a ~el :~UL~ application assembly 26, which assembly includes a pair of spaced apart discs 10 28 and 30, the discs being connected in spaced relation by a vertical support member 32. Disc 28 is normally positioned to reside on the top surface of plate 18 with the vertical support 32 slidably moveable within opening 20 of plate 18. In this manner, disc 30 is adapted to seat on spaced apart support members 22 and 24. The assembly 26 is freely vertically moveable within the frame 12.
Support member 22 and 24 not only impart structural integrity to the frame 12, but also serve to receive the sampling 20 assembly, broadly denoted by numeral 34. In this manner, support me_bers 22 and 24 each include registering apertures 36 therethrough. The support members 22 and 24 are spaced apart sufficiently to ~ te two ;n~pen~nt pivoting blocks 38 and 40 which blocks are positioned between support members 22 and 25 24 and are pivotally connected therebetween by registration of apertures 36 with c~LL~ n~lin~ ~peL~ULeS 42 ~Yt~n~;n~ through each of the pivoting blocks 38 and 40. Pins 44 movably mount the blocks 38 and 40 between the support members 22 and 24.
With greater specificity concerning the blocks 38 and 40, in one possible embodiment, the blocks each include an .omho~lir 46 and 48 and a recessed segment 50 and 52. The recessed ~gr CS 50 and 52 are each configured to receive a portion 54 and 56 of the example ~: 1 in~ injection member. Each portion 54 and 56 subscribes to a generally half cylinder form with the extreme ends of each member 54 and 56 including a chamfered or otherwise angled segment 58 and 60, which permits easy penetration through a material to be sampled. The opposed ends of each of the members 54 and 56 includes a removed segment 62 for permitting pivoting r v~c ~ of each section 54 and 56 away rrom one another. Optionally ~ r~ d within each member 54 and 56 is a support 64 and 66 each of which includes a aperture 68 extending therethrough and for registration with apertures 70 and 72 on members 54 and 56.
once each member 5g and 56 is positioned within its respective recess 50 or 52 of blocks 38 and 40 respectively, apertures 74 and 76 of blocks 38 and 40 respectively register with apertures 70 and 72. An adjustable bolt or other suitable fastener 80 is then positioned through the apertures to retain the members 54 and 56 within the blocks 38 and 40.
In operation, when one i8 desirous of obtaining a sample from, for example, a soil, the apparatus is simply positioned above the soil, and the operator applies a pressure to disc 28, which in turn transmits the force thereon to disc 30. This so applied force is realized by the abutment 46 and 48 on pivoting blocks 38 and 40, which are connected to the g 1 in~ half cylinders 54 and 56. As the force is applied to the abutments 46 and 48, members 54 and 56 are urged together to therefore make the penetration into the soil relatively rapid and smooth due to the semi-cylindrical shape of each of the members.
once the soil or other material has been penetrated, the operator wishes to remove the assembly 10 from within the material, a lifting assembly 82 is employed to lift assembly 26 and therefore remove the assembly 34 from within the sample.
Lifting assembly 82 is pivotally connected to frame 12 by the cooperation of supports 84 and 86 each having apertures 88 therethrough. The lifting assembly includes a U-shaped handle member 90 having two spaced apart lifters 92 and 94, each having apertures 96 for registration with ~peL~uL~s 88. A pin 98 mounts the lifting assembly 82 to frame 12. The two lifter members are positioned so that they are beneath the surface of disc 28 and g therefore, when one desires to remove the assembly 34 from within the sample, the user simply urges lifters 92 and 94 into contact with the underside of disc 28 which therefore results in the remove of assembly 34 from within the sample. An additional 5 handle 100 may be positioned on the apparatus 10 as shown in the drawings or in another convenient location.
~ rurning to Figure 3, shown is a sectional view of one of the sleeves 54 and 56, which includes internally and spaced from the bottom portion 58 and a lip 104. Lip 104 is useful to relieve the internal diameter of the hollow sampler above the cutting edge to facilitate quick sample release. Sleeve 56 includes 6imilar features.
Figure 4 illustrates a further possible 'i L
c~n~Drnin~ the lip arrangement and in the embodiment shown, each half cylinder 54 and 56 (54 shown only), includes a further lip 108 spaced from the corresponding lip 104. In this manner, a retaining area 112 is provided to receive a sample receptacle 20 (shown in chain line), an example of which is shown in Figure 5 and denoted by numeral 114. Deron~inq on the nature of the material to be sampled, for eYample, soil, it may be desirable to have the sampled material within a small open-ended hollow receptacle so that the entire sample can be readily removed from 25 between sleeves 54 and 56 for simple and easy removal and 8~lhq~ nt study of the sampled material.
Although a specific ~ -nt of the arr~n5~ ~ has been shown, it will be readily apparent that the length of the half 30 cylinders 54 and 56 can be any suitable length and that the entire apparatus may be power assisted or otherwise mechanically driven thus avoiding the use of user applied force.
Although: ~ Ls of the invention have been described 35 above, it is not limited thereto and it will be apparent to those skilled in the art that numerous modifications form part of the present invention in~ofar as they do not depart from the spirit, nature and scope of the claimed and described invention.
The present invention relates to a sampling device and more particularly, the present invention relates to an improved sampler which can be used in, for example, the soil sampling f ield .

The support members 22 and 24 are spaced apart sufficiently to ~ te two ;n~pen~nt pivoting blocks 38 and 40 which blocks are positioned between support members 22 and 25 24 and are pivotally connected therebetween by registration of apertures 36 with c~LL~ n~lin~ ~peL~ULeS 42 ~Yt~n~;n~ through each of the pivoting blocks 38 and 40. Pins 44 movably mount the blocks 38 and 40 between the support members 22 and 24.
With greater specificity concerning the blocks 38 and 40, in one possible embodiment, the blocks each include an .omho~lir 46 and 48 and a recessed segment 50 and 52. The recessed ~gr CS 50 and 52 are each configured to receive a portion 54 and 56 of the example ~: 1 in~ injection member. Each portion 54 and 56 subscribes to a generally half cylinder form with the extreme ends of each member 54 and 56 including a chamfered or otherwise angled segment 58 and 60, which permits easy penetration through a material to be sampled. The opposed ends of each of the members 54 and 56 includes a removed segment 62 for permitting pivoting r v~c ~ of each section 54 and 56 away rrom one another. Optionally ~ r~ d within each member 54 and 56 is a support 64 and 66 each of which includes a aperture 68 extending therethrough and for registration with apertures 70 and 72 on members 54 and 56.
once each member 5g and 56 is positioned within its respective recess 50 or 52 of blocks 38 and 40 respectively, apertures 74 and 76 of blocks 38 and 40 respectively register with apertures 70 and 72. An adjustable bolt or other suitable fastener 80 is then positioned through the apertures to retain the members 54 and 56 within the blocks 38 and 40.
In operation, when one i8 desirous of obtaining a sample from, for example, a soil, the apparatus is simply positioned above the soil, and the operator applies a pressure to disc 28, which in turn transmits the force thereon to disc 30. This so applied force is realized by the abutment 46 and 48 on pivoting blocks 38 and 40, which are connected to the g 1 in~ half cylinders 54 and 56. As the force is applied to the abutments 46 and 48, members 54 and 56 are urged together to therefore make the penetration into the soil relatively rapid and smooth due to the semi-cylindrical shape of each of the members.
once the soil or other material has been penetrated, the operator wishes to remove the assembly 10 from within the material, a lifting assembly 82 is employed to lift assembly 26 and therefore remove the assembly 34 from within the sample.
Lifting assembly 82 is pivotally connected to frame 12 by the cooperation of supports 84 and 86 each having apertures 88 therethrough. The lifting assembly includes a U-shaped handle member 90 having two spaced apart lifters 92 and 94, each having apertures 96 for registration with ~peL~uL~s 88. A pin 98 mounts the lifting assembly 82 to frame 12. The two lifter members are positioned so that they are beneath the surface of disc 28 and g therefore, when one desires to remove the assembly 34 from within the sample, the user simply urges lifters 92 and 94 into contact with the underside of disc 28 which therefore results in the remove of assembly 34 from within the sample. An additional 5 handle 100 may be positioned on the apparatus 10 as shown in the drawings or in another convenient location.
~ rurning to Figure 3, shown is a sectional view of one of the sleeves 54 and 56, which includes internally and spaced from the bottom portion 58 and a lip 104. Lip 104 is useful to relieve the internal diameter of the hollow sampler above the cutting edge to facilitate quick sample release. Sleeve 56 includes 6imilar features.
Figure 4 illustrates a further possible 'i L
c~n~Drnin~ the lip arrangement and in the embodiment shown, each half cylinder 54 and 56 (54 shown only), includes a further lip 108 spaced from the corresponding lip 104. In this manner, a retaining area 112 is provided to receive a sample receptacle 20 (shown in chain line), an example of which is shown in Figure 5 and denoted by numeral 114. Deron~inq on the nature of the material to be sampled, for eYample, soil, it may be desirable to have the sampled material within a small open-ended hollow receptacle so that the entire sample can be readily removed from 25 between sleeves 54 and 56 for simple and easy removal and 8~lhq~ nt study of the sampled material.
Although a specific ~ -nt of the arr~n5~ ~ has been shown, it will be readily apparent that the length of the half 30 cylinders 54 and 56 can be any suitable length and that the entire apparatus may be power assisted or otherwise mechanically driven thus avoiding the use of user applied force.
Although: ~ Ls of the invention have been described 35 above, it is not limited thereto and it will be apparent to those skilled in the art that numerous modifications form part of the present invention in~ofar as they do not depart from the spirit, nature and scope of the claimed and described invention.
