I, HIS ATTORNEYS United States Patent 3,196,229 CORE BOX Theodore D. Glass, 355 Phoenix Ave, Ehester, W. Va. Fiied Mar. 28, 1%3, Ser. No. 269,342 Claims. (Cl. 2l665) This application is a continuation-in-part of my application Serial No. 112,042, filed May 23, 1961, now abandoned and relating to a core box.
This invention relates to boxes, and more particularly to core boxes for storing and maintaining therein core produced by test drilling and expoloration of deposits of ores, minerals and the like.
In test boring for ores, minerals and the like, it is frequently necessary to bore into the earth for many hundreds of feet. These test borings are made with well-known equipment and it is necessary that the test boring, known as the core, be saved for subsequent analysis. The core is a continuous cylinder composed of the transverse strata of the earth. It is necessary that the core be withdrawn from the test hole and maintained in storage in the sequence in which it is withdrawn so that the depth will be known from which a particular part of the core was cut. Conventional wood core boxes are presently widely used for storing the core removed from the test hole. These boxes consist of a conventional multisided box into which the core is placed in proper sequence with wooden dividers inserted randomly transversely of the core and marked with the footage depths from which the core was out. These known wooden core boxes are expensive, bulky, lack the desired durability for their intended use, and have only a limited life.
My invention overcomes the deficiencies and shortcomings of the conventional wooden core boxes and provides a durable, rigid, weather resistant, compact core box which requires a minimum of storage space while greatly increasing core storage capacity for the space required by the box. Specifically, my invention is a box comprising a first divider which has integral end and side walls forming a polygon. A continuous, rigid separator within the polygon is afiixed to the walls thereof and is corrugated with ridges and valleys on the top and undersides thereof. The valleys hold the core and one of the end and side walls closes the ends of each valley for the depth thereof. The ridges separate the valleys from one another and the top surface of each ridge for the length thereof is disposed in the same plane as the top and underside surfaces of that one of the end and side walls which closes the ends of the valleys. A second divider identical to the first one is positioned over the first divider with the Walls of the dividers in alignment and with the valley on the underside of the second divider positioned over the valleys on the top side of the first divider. Thus, the ridges and the top and bottom surfaces of the dividers meet in an abutting engagement to form a plurality of closed chambers for containing the core. The first and second dividers form the box.
In one embodiment of the box, the top surface of each ridge'for the length thereof is substantially fiat.
Preferably, the dividers are held together as a unit by a locking means.
By adding a third divider identical to the first two, and positioning it over the second divider with the walls of the dividers in alignment, I double the capacity of the box formed by two dividers. Disposition of the third divider over the second one is such that the valleys on the underside of the third divider are over the valleys on the top side of the second divider and the ridges of the second and third dividers meet to form a second row of a plurality of closed chambers. The first, second and third dividers then form the core box.
In the drawings, I have shown present preferred embodiments of my invention, in which:
FIGURE 1 is an isometric view of one embodiment of my invention;
FIGURE 2 is a sectional view taken on line IIII of FIGURE 1;
FIGURE 3 is a sectional view taken on line IIIIII of FIGURE 1;
FIGURE 4 is a sectional view taken on line IV--IV of FIGURE 1;
FIGURE 5 is a side elevation view of my core box;
FIGURE 6 is a cross-sectional view similar to FIG- URE 2 showing a second embodiment of my core box adapted to store various sizes of core;
FIGURE 7 is a cross-sectional view similar to FIG URE 6;
FIGURE 8 is a cross-sectional view similar to FIG- URE 6;
FIGURE 9 is a section view similar to FIGURE 6 but with the upper divider reversed and turned 180 about its horizontal axis disposed perpendicularly to the ridges and valleys thereof;
FIGURE 10 is a fragmentary vertical section view of a third embodiment of my invention; and
FIGURE 11 is a view similar to FIGURE 10 but with the top divider reversed and turned 180 about its horizontal axis disposed perpendicularly to the ridges and valleys thereof. Referring to FIGURES 1-5, inclusive, my core box comprises a first divider 10 which is assembled with a second identical divider 11 to form the box. Additional dividers such as the third identical divider shown assembled with dividers 10 and 11 can be combined to increase storage capacity. The addition of the third divider doubles the storage capacity of the box formed by dividers 1t and 11 while increasing storage requirements for the box of the three dividers by 50%.
Each divider includes side walls 12 and 13, and end walls 14 and 15. A corrugated separator 16 is positioned within and molded integral with the walls. Thus each side of the dividers presents ridges and valleys which run for the extent thereof.
The core to be stored in the core box is in three basic sizes: 1% inch diameter which is known as AX core, 1% inch diameter which is known as BX core, and 2% inch diameter core which is known as NX core.
The BX core is the most popular and accounts for approximately of the boring. Thus, my box is primarilyconstructed to store the BX core.
For a box for storing 1% inch diameter BX core, the box is approximately 15 /4 inches wide (the front face of FIGURE 1) and 30 inches long (the right side face of FIGURE 1). The walls of the separator 16 at the point 17 separating the various core samples are about Ms inch thick when fabricated from a durable plastic. The dimensions of the box vary with the size core being stored and the rigidity desired in the box. I have found the dimensions stated herein to be desirable and accomplish the purpose for which the box is intended.
A pair of outwardly extending tongues 18 are affixed to each side wall 12 and 13. Each tongue contains a pair of spaced openings 19 and 20. As shown in FIG URES 2 and 5, a bolt 23 is positioned in one of the holes in a tongue of divider l0 and an aligned hole in divider 11. A square or wing nut 22 is threaded on the bottom of the bolt and maintains the dividers in locked relationship to each other. A single bolt is inserted through the aligned holes in each of the four tongues spaced around the divider periphery. When As additional dividers are added to the box, this staggered arrangement of the bolts is continued. This arrangement of the bolts permits removal of only one of the dividers at a time while maintaining other dividers in locked relationship to each other. The spaced holes 19 and 20 also provide at least one extra hole at each corner in the event that one of the holes becomes unusable.
My invention also is usable by inserting a long bolt through three or more aligned holes at each corner and threading a nut on the bottom of the bolt.
The nuts 22 are located sufficiently near the walls 125 and 13 so that one side of the nut engages the wall to prevent turning of the nut while the bolt is being tightened or loosened. V
The divider 16 is basically a corrugated sheet but has fiat areas 24 at the top of the ridges and bottom of the valleys as shown in FIGURE 2, and these fiat areas extend across the divider for the length of the ridges and valleys. Each flat area has a wide groove 25 extending along the ridge of the corrugated sheet. A tape 26 is glued in each groove and appropriate markings recorded on the tape 26 to indicate the depth from which the 'adjoining core was taken.
I have shown the core 27 completely enclosed in FIG- URE 2 between corrugated sheets 16 of three separate dividers. The core 27 shown in FIGURE 2 is of any desired diameter such as the AX, BX or NX core described above. I have shown small spaces 28 above and below the cores and, although these spaces are desirable, they are not absolutely necessary in my box. Therefore, the spaces 28 may be rounded to conform to the shape of the core 27.
The flat areas 24 are in abutting relationship as shown in FIGURE 2 when the dividers are assembled. Likewise, theend walls of the dividers meet in abutting relationship thereby maintaining the core 27. Within a closed chamber within the divider. The end Walls 14 and 15 close the ends of the chamber for the depth of the valleys (FIG- URE 1) so that the core is maintained dry and undisturbed by the completely enclosed chamber.
I also provide a wide groove 29 in one or more of the outside walls of the dividers. A tape 30 is positioned in the recess and data relating to the cores within the di vider is recorded on the tape. This data may include hole number, feet of core, etc. The tape 39 is protected from the weather by being recessed into the wall.
-With'a 30-inch long box, each pairs of dividers will hold 12 /2 feet of core or three dividers, as shown in FIGURE 2, will hold 25 feet of core. This is substantially more core per unit volume of core box than couldbe stored in the wooden core boxes.
i In FIGURE 6, I have shown a second embodiment of my core box which is basically the same configuration as described in FIGURE 2 with the exception that the corrugated dividers are constructed to hold two sizes of core 31 and 32. The dividers have large valleys. on one side and small valleys on the other side. As shown in FIG- URE 6, the large valleys are aligned to form chambers for big diameter core, and the small valleys are aligned to form chambers for small diameter core. This configuration accomplishes maximum. core storage in minimum core box volume; The boxes shown in FIGURES 6,.7
and 8 are fastened together in the same manneras described with respect to the box of FIGURES land 2. I
of the core. The elimination of spaces 34 around core 31 is also possible as explained above.
The advantage of the core box shown in FIGURE 6 is that it provides for storage of various sizes of cores. The upper smaller chambers shown in FIGURE 6 are specifically adapted to receive a 1% inch diameter core (BX) but will also hold a 1%. inch diameter core (AX). The lower larger chambers are adapted to receive a 2 /8 inch diameter core (NX). v
The tops of the ridges of the embodiment of FIGURES 6-9 have flat areas 24a the same as the tops of the ridges of the embodiment of FIGURES 1 5 and these flat areas 24a extend across the divider for the length of the ridges. As shown in FIGURES 69, these flat areas 24a are in abutting relationship when the dividers are assembled and these areas are located in the same plane as the top and underside surfaces (FIGURE9) of the side and end walls of the dividers HM and 11a with side wall 13a and its top surface 40 and underside surface'l being shown. The ilat areas24 of the embodiment of FIGURES 1-5 have the same disposition relative to the top and underside surfaces of the side and end walls 12, 13, Hand 15 of the dividers Ill and 11 and of the third divider.
Disposition of the top surfaces of the ridges in the same plane as the top and underside surfaces of the end and side walls of each divider permits the divider to be reversed and turned about that horizontal axis thereof disposed transversely of the ridges and valleys thereof or about that horizontal axis disposedparallel to the ridges and valleys. This is shown by FIGURE 9 wherein divider 10a haslbeen reversed so that the divider Ilia receives support in its reversed position from cooperation between the top and underside surfaces of the end and side walls for maintaining it in the reversed position. Such a disposition also imparts to the core box ability for two dividers to form the box without use of a frame, any additional supports or other members.
FIGURE 7 illustrates the second embodiment of my core box which is used to store only the smaller cores 32. The empty chambers are not used at all; however, the box shown in FIGURE 7 is not as economical to use as the boxes shown in FIGURES 2 and 6. V
FIGURE 8 illlustrates the box of FIGURE 6 used for storing only the larger core .31. Likewise, this box is not as economical to use as that shown in FIGURES 2' and 6.
FIGURES 10 and 11 Sl'lOW a third embodiment of my invention comprising dividers 42 and 43 and 44, each of which is identical to one another and includes side walls and end walls (only sidewall being shown) for forming a polygon. Also, each divider. has a corrugated separator 46 which defines ridges 47 and valleys 48 on both the top and undersides thereof. The top surface of each ridge has a fiat area 49 which extends acrossthe divider for the length'of the ridges. Like the embodiment of FIGURES 15, the end walls and the flatareas of this embodiment abut when the dividers are assembled with the walls in alignment to form closed chambers 59 witliin the box composed of the dividers. The end walls also close the ends of the chambers. for the depth of the valleys as is the case with theembodiment of FIGURES 15 to completely enclose the chambers iiil. v
For those valleys such as valley' lda of divider 42 positioned adjacent the side wall 45 of the divider, such side wvall 45 forms an outer wall 51 of the valley As shown in FIGURES l0 and .11, in the plane of the top surface of each ridge the Width of each ridge throughout its length is greater than the Width of the opening of each valley into the plane or" the top surface of each ridge. In fact, the top'surface of each ridge is wider than any Width of each valley-for the depth thereof. Additionally, and like the other two embodiments of FIG URES 1-5 and 6 9, the top surface of each ridge on the top and 'undersides of each separator 46 is in the same plane as the top and underside surfaces of the side and end walls of each divider, top surface 52 and underside surface 53 of side Wall 45 being shown. Such an arrangement not only imparts reversibility to each divider, but also, when a divider is reversed, it provides a closed chamber 54 of substantially one-half the volume of the chambers 59 formed by the combination of two dividers. Thus one-half the core can be used for chemical analysis and the remainder stored in closed cha nbers 5d of the divider 43 and formed by the combination of the dividers 2-2 and 43 with the divider reversed and turned 180 about its horizontal axis disposed transversely of the ridges and valleys thereof from the position of FIGURE to the position of PEGURE ll.
I prefer to fabricate my box from a natural or synthetic plastic material of either the thermoplastic or thermosetting type. The primary requirement of the material is that it form a rigid box which is strong and weather resistant. I prefer to use a clear transparent plastic material which provides a good view of the inside core materials. A specific example of the material which 1 can use is polyethylene or hard rubber. Any of the plastic materials which I use can be reinforced with glass fiber or a similar reinforcement. The many synthetic plastics which I can use are well-known and are set forth on page 665 of Eackhs Chemical Dictionary Julius Grant, published by the Blalriston Company in 1950, which is incorporated by reference herein. Since the time of ub lication of this book, there has been developed many new new plastic materials which are equally suitable for my box. My box can also be made from metal, wood, glass fibers bonded together by a suitable resin, etc.
My invention has important advantages which include formation of a core box by a combination of two or more dividers positioned over one another with their walls in alignment. Two such dividers require no other piece, frame or member to form the core box, and three such dividers comprise a core box with the same capacity as two conventional core boxes, but at substantially less cost and with a requirement for about 50% less storage space. Furthermore, the structure of my core box is stronger, more durable and more rugged and enjoys a greater service life than that of the known core boxes.
Also, some of the embodiments of my invention have a reversible feature wherein one divider is turned 180 about one horizontal axis disposed perpendicularly to the ridges and valleys thereof or about a second horizontal axis disposed parallel to the ridges and valleys. After such reversal, the core box has twice as many chambers and, in some cases, twice as many completely enclosed chambers and two such dividers form a complete box.
Additionally, the core box lends itself to low cost manufacture, namely, production of a single divider which is usable in one of two reversible positions with one or more additional identical dividers to form a core box composed of the two or more dividers and Without requirement for an additional frame, member, part, etc.
