To all whom; t may concern: l
Be it known that I, MILLER L. MELBERG, citizen of the United States, residing at Bloomer, in the county of Chippewa and State of Wisconsin, have invented certain new and useful ImprovementsV in Soil- Testers, of which the following is a specification.
This invention relates to new and useful.
improvements in soil testers, and has particular reference to that type of suchv devices which are provided with soil receiving receptacles such as permit the samples of the earth or soil to be hermetically sealed and placed in storage until such time as it is desired to analyze the samples.
As its principal object, the presentA invention aims .to 'provide a soil tester co-nsisting essentially in a cylindrical body tube which is tapered at its lower terminal and carries thereat a sharpened mouth-piece which may be bored into the ground so that a cylindrical filler of earth will be projected upwardly into the body tube and into a glass tube or magazine which is removably placed in the body tube.
A further object is to construct the soil tester of the present invention with such regard to proportion, number and arrangement of parts that it may be cheaply manufactured, will be- .durable and efficient in its action, and will permit the operator to obtain the sample of soil with-a minimum qexpenditure of time and labor. y
A still further object isto construct the body tu-be of the tester in such manner that a soil receiving magazine or tube may be quickly inserted or withdrawn, thus making it possible to collect a relatively large number of samples in a comparatively short time. l( p The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out inthe claims which are appended hereto and form a part of this application.
I Vith reference to thel drawings,V wherein there has been illustrated .the preferred embodiment of this invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a longitudinal section taken through the device, illustrating the various elements in complete assembled relation; Fig. 2 is a detail view illustrating a magazine which has been filled with soil and is corked at each end; Fig. 8 is a detail View showing an en larged sectional Viewv of the lower terminal of the instrument. This figure discloses particularly the manner in which the cutting element is secured to the body tube; and Fig. 4 is an enlarged perspective view illustrating in detail the manner in which the lower terminal of the body tube is formed.
Proceeding now to the description of the drawings, the preferred embodiment of this invention, as best illustrated in Fig. 1, includes a metallic .body shell or cylinder, a removable handle, a removable magazine arranged within the body shell, and a soil cut- 'ting member carried by the body cylinder.
The body cylinder, as illustrated in Fig. 1, is preferably cylindrical in shape, being formed in the nature of an elongated tube which may be of any suitable diameter or length, although in practice it has been found expedient to employ a tube approximately twelve (12) inches inlength and one and -one-eighth (1%) inches in diameter. This body member 10 is preferably constructed from a drawn nickeled brass tube, although, if so desired, relatively thin steel tubing or any other metal may be employedv without departing from the spirit of this invention, it being perfectly obvious that the material from which the member 10 is constructed is a purely arbitrary matter, and oneto be governed solely by the conditions under which the device is manufactured.
The upper terminal of the member 10 is formed with diametrically' opposed bayonet slots 11 which are designed to receive the studs 12 o-f the handle 13. In passing it may be well to mention the fact that the handle 13 inthe preferred embodiment is greatly .similar to an ordinary shovel or spade handle and carries a tubular extension 14 interiorly of which at diametrically opposed points are disposed the studs 12 above mentioned. The purpose for which ythe handle 13 is detachable from the body .member 10 will be hereinafter more fully fdisclosed in that portion of the specification devoted to the description of the operation of the device.-
p The lower terminal of the'body member A10 is incised a number of places, as at 15. These incisions extend longitudinally of the body member and are V-shaped so that the four tongues l'which are produced by lby employing the novel form of structure A making the incisions may be bent inwardly so as to engage at their lower ends against a cutting tube 17. This cutting tube 17 extends into the body tube 10 a considerable distance and also projects exteriorly of the tongues 16. As will be observed upon reference to Fig. 1, a filler of solder is poured between the tongues 16 and the inwardly projecting portion of the cutting member 17, as indicated at 18, This solder filling 18 terminates a slight distance short of the inner edge of the member 17 and is adapted toserve as a supporting base for the glass cylinder or soil magazine which is placed in the body member 10 when a sample of soil is to be collected, as will be hereinafter explained. It will be noted u on .reference to Fig. l that an annular cham er 1s formed between the inner end of the cutting tube 17 and the body tube l0, a solder ller constitutin the bottom wall of this chamber. It has geen found necessary in practice to lsharpen the lower edge ofthe cutting tube 17 so that the tester may be quickly inserted in the ground.l The soil magazine, 1nd1- cated at 19, is, as previously set forth, preferably formed from a length of glass tubing. If desired, however, a metallic tube ma of course, be employed.
Clbming now to the description of the manner in which the tester of this invention is employedzThe operator first inserts the glass tube 19 in the body member 10. When the tube has been inserted, its lower terminal will be disposed between the body member 10 and the inner terminal of the vcutting tube 17, its lower edge being supported on the solder filler. A cork is then placed in the upper terminal of the glass tube, and the handle 13 is applied by inserting the studs in the bayonet slots and giving the handle a quarter turn. The device is then ready for use. The cutting tube 17 is inserted in the ground and the body tube 10 rotated during the insertion of the cutting member, that is, if such manipulation be necessary, as when the round is hard and packed. After the bc y tube 10 has been inserted in the ground the desired distance, the operator pulls the tube out of the ground and in inverting it forces the earthfrom the cutting member 17 into the.
magazine. Thehandle is then removed an the magazine withdrawn. It then remains to insert a cork or a similar sealing device in the open end of the glass tube, and the soil may then be stored away for any desired length of time.
Relative to the many advantages obtained hereinbefore described, it is desired to first direct particular attention to the formation of the lower terminal of the body tube 10. By bending the tongues 16 inwardly and soldering them to the cutting member 17,
as in Fig. l, there is Aproduced a substan- In reduction to practice, it has been found that the form of this inventienillustrated .in the drawings, and referred to in the above description as the preferred embodiment, is the most efiicient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desired to emphasize the fact that various'minor changes in details of constrguction, uproportion and arrangement yof parts may be resorted to, when required,
without sacrificing any of the advantages of this invention, as defined in the appended claims. c
