DETAILED DESCRIPTION

[0025] In the following detailed description, numerous specific details are set forth to provide a thorough understanding of the present invention. The disclosed embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, or structures may not have been described in detail so as not to obscure the present invention.

[0026] The invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0027] Certain features of the invention that are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention that are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination.

[0028] In accordance with FIGS. 1-6, a storage rack 10 is provided for storing one or more mine tools for being connected to a mining machine 12. The mining machine may be, for example, a vehicle with wheels or tracks including a boom 14 with the ability to raise and maneuver the mine tool when connected thereto. The mine tools may comprise any desired type of tools or implements for being used during a mining operation, such as for example a scaler or pick 16, a cutter 18, or any other item useful for dislodging materials from a face of a mine location, such as an underground passage, but possibly at above-ground locations as well (such as pit or strip mines).

[0029] Each of the mining tools 16, 18 includes a connector 20, as indicated in FIG. 6. In the illustrated example, this connector 20 comprises a pair of generally parallel, horizontal bars 20a, 20b. These bars 20a, 20b may be sized, shaped and otherwise arranged for engaging a connector having corresponding receivers or hooks 22a, 22b associated with and forming a means of connection on a head end of the boom 14 to form a selective engagement with the tool when desired for use. One or more of the tools 16, 18 may also include an auxiliary connector 24 for establishing a powered (hydraulic) connection with the mining machine 12 to facilitate movement of the tool relative to the boom 14 (e.g., including rotation of a cutting head in the case of the cutter 18). The particular types or arrangement of connectors 20, 24 is not considered essential to the practice of the invention disclosed.

[0030] According to one aspect of the disclosure, the storage rack 10 is adapted for supporting the tools, such as pick 16 and cutter 18, in a manner that facilitates establishing a quick and reliable connection with the mining machine 12. Specifically, as perhaps best understood from FIGS. 1, 2 and 3, the tools 16, 18 are supported within distinct compartments 10a, 10b of the rack with the respective connectors facing upwardly and at an angle, thus facilitating establishment of the connection from above when the boom 14 is oriented above the rack 10 and lowered into position in engagement with the tool 16, 18 (such that the corresponding connectors, in this example bars 20a, 20b and receivers or hooks 22a, 22b, may engage and establish a secure, but releasable connection). Withdrawal of the boom 14 once connected thus allows the tool 16 or 18 to be freely lifted from the storage rack 10 for use (such as cutter 18 in FIG. 7), and then returned in a similar manner for exchange, as necessary or desired for a particular mining operation.

[0031] In the particular embodiment illustrated, it can be understood that each compartment 10a, 10b is adapted for receiving a differently shaped tool, yet holds it in an orientation such that the associated connector 20 is presented at the same position (e.g., height and angle) for connection, which helps to speed connection time and ensure repeatability. In the version shown, the first compartment 10a is adapted for receiving a scaler 16, which is a relatively squat tool with a majority of it extending in a generally vertical direction. Thus, as shown in FIG. 3, this portion of the rack 10 includes generally angled, laterally spaced supports 10c, 10d for engaging and supporting the scaler 16 in an upright condition, with the associated connector 20 extending at an angle relative to the vertical and horizontal planes.

[0032] In the illustrated example, the other compartment 10b is adapted for receiving a cutter 18, which as shown in an elongated tool. Thus, the rack 10 includes longitudinally spaced shelves 10e, 10f for supporting upper and lower portions of the cutter 18 forward of the connector 20. Still, as can be appreciated, the same general orientation of the connector 20 is achieved. Of course, it is possible to provide different arrangements for different tools, or the same arrangement for a variety of similar tools (e.g., multiple cutters or scalers having different working implements).

[0033] According to a further aspect of the disclosure, the storage rack 10 itself is adapted for forming a connection with the mining machine 12. As perhaps best understood from FIGS. 1, 3, and 4, this may be achieved by providing the rack 10 with an integral connector 26 for connecting to the boom 14 in the same or a similar manner as each of the mining tools the storage rack is adapted to receive. Specifically, the connector 26 includes a pair of generally parallel, horizontal bars 26a, 26b for connecting with the receivers or hooks 22a, 22b, as shown in FIG. 6, which connector may be oriented in the same manner as the connector(s) 20, 24 of the associated tools, as illustrated.

[0034] The connection once established between the mining machine 12 and connector 26 thus allows for the entire storage rack 10 including the tools to be carried about for relocation, as desired. The mining machine 12, such as via the receiver 22 of the boom 14, may then be disconnected and reconnected to a particular tool in a quick fashion, avoiding the need for a separate vehicle to transport the tools to the location of the mining machine 12 (but in this regard, it is noted that the rack 10 may be provided with tubular members or receivers 28, such as along a base thereof, for receiving the forks of a forklift to facilitate raising or lowering the rack, as may be desired).

[0035] Summarizing the disclosure, a storage rack 10 is providing for storing a plurality of mining tools, each adapted for connecting to a mining machine, and the storage rack itself is also itself adapted for connecting with the mining machine. In this manner, a single mining machine may be used to not only readily connect with the different tools being stored, but may also be used to transport the tools about to different locations for use as desired. Enhanced efficiency and profitability of the mining operation may thus result.

[0036] Each of the following terms written in singular grammatical form: a, an, and the, as used herein, means at least one, or one or more. Use of the phrase One or more herein does not alter this intended meaning of a, an, or the. Accordingly, the terms a, an, and the, as used herein, may also refer to, and encompass, a plurality of the stated entity or object, unless otherwise specifically defined or stated herein, or, unless the context clearly dictates otherwise. For example, the phrases: a unit, a device, an assembly, a mechanism, a component, an element, and a step or procedure, as used herein, may also refer to, and encompass, a plurality of units, a plurality of devices, a plurality of assemblies, a plurality of mechanisms, a plurality of components, a plurality of elements, and, a plurality of steps or procedures, respectively.

[0037] Each of the following terms: includes, including, has, having, comprises, and comprising, and, their linguistic/grammatical variants, derivatives, or/and conjugates, as used herein, means including, but not limited to, and is to be taken as specifying the stated components), feature(s), characteristic(s), parameter(s), integer(s), or step(s), and does not preclude addition of one or more additional components), feature(s), characteristic(s), parameter(s), integer(s), step(s), or groups thereof. Each of these terms is considered equivalent in meaning to the phrase consisting essentially of. Each of the phrases consisting of and consists of, as used herein, means including and limited to.

[0038] The phrase consisting essentially of, as used herein, means that the stated entity or item (system, system unit, system sub-unit device, assembly, sub-assembly, mechanism, structure, component element or, peripheral equipment utility, accessory, or material, method or process, step or procedure, sub-step or sub-procedure), which is an entirety or part of an exemplary embodiment of the disclosed invention, or/and which is used for implementing an exemplary embodiment of the disclosed invention, may include at least one additional feature or characteristic being a system unit system sub-unit device, assembly, sub-assembly, mechanism, structure, component or element or, peripheral equipment utility, accessory, or material, step or procedure, sub-step or sub-procedure), but only if each such additional feature or characteristic does not materially alter the basic novel and inventive characteristics or special technical features, of the claimed item.

[0039] The term method, as used herein, refers to steps, procedures, manners, means, or/and techniques, for accomplishing a given task including, but not limited to, those steps, procedures, manners, means, or/and techniques, either known to, or readily developed from known steps, procedures, manners, means, or/and techniques, by practitioners in the relevant field(s) of the disclosed invention.

[0040] Throughout this disclosure, a numerical value of a parameter, feature, characteristic, object or dimension, may be stated or described in terms of a numerical range format. Such a numerical range format, as used herein, illustrates implementation of some exemplary embodiments of the invention, and does not inflexibly limit the scope of the exemplary embodiments of the invention. Accordingly, a stated or described numerical range also refers to, and encompasses, all possible sub-ranges and individual numerical values (where a numerical value may be expressed as a whole, integral, or fractional number) within that stated or described numerical range. For example, a stated or described numerical range from 1 to 6 also refers to, and encompasses, all possible sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and individual numerical values, such as 1.3, 2, 2.8, 3, 3.5, 4, 4.6, 5, 5.2, and 6, within the stated or described numerical range of from 1 to 6. This applies regardless of the numerical breadth, extent or size, of the stated numerical range.

[0041] Moreover, for stating or describing a numerical range, the phrase in a range of between about a first numerical value and about a second numerical value, is considered equivalent to, and meaning the same as, the phrase in a range of from about a first numerical value to about a second numerical value, and, thus, the two equivalents meaning phrases may be used interchangeably. For example, for stating or describing the numerical range of room temperature, the phrase room temperature refers to a temperature in a range of between about 20 C. and about 25 C., and is considered equivalent to, and meaning the same as, the phrase room temperature refers to a temperature in a range of from about 20 C. to about 25 C.

[0042] Terms of approximation, such as the terms about, substantially, approximately, etc., as used herein, refers to 10% of the stated numerical value. Generally polygonal means that the shape has flat surfaces, as with a polygon, but may have rounded corners connecting these surfaces.

[0043] The phrase operatively connected, as used herein, equivalently refers to the corresponding synonymous phrases operatively joined, and operatively attached, where the operative connection, operative joint or operative attachment, is according to a physical, or/and electrical, or/and electronic, or/and mechanical, or/and electro-mechanical, manner or nature, involving various types and kinds of hardware or/and software equipment and components.

[0044] It is to be fully understood that certain aspects, characteristics, and features, of the invention, which are, for clarity, illustratively described and presented in the context or format of a plurality of separate embodiments, may also be illustratively described and presented in any suitable combination or sub-combination in the context or format of a single embodiment. Conversely, various aspects, characteristics, and features, of the invention which are illustratively described and presented in combination or sub-combination in the context or format of a single embodiment may also be illustratively described and presented in the context or format of a plurality of separate embodiments.
