Rock tumblers are devices that provide a way to smooth and polish irregularly shaped hard objects, such as stones. A grinding medium, sometimes comprising an aqueous solution of water and an abrasive, are enclosed in a container, such as a barrel, along with the irregularly shaped hard objects. As the apparatus tumbles or is agitated, the abrasive makes repeated contact with the hard objects and over time, smooths and polishes the objects.

In addition to the example, aspects and embodiments described above, further aspects and embodiments will become apparent by study of the following descriptions. The summary above is a list of example implementations, not a limiting statement of the scope of the disclosure.
The accompanying figures, which are incorporated herein and form a part of the specification, illustrate some, but not the only or exclusive, example embodiments and/or features. It is intended that the embodiments and figures disclosed herein are to be considered illustrative rather than limiting.
The drawings have not necessarily been drawn to scale. Similarly, some components and/or operations may be separated into different blocks or combined into a single block for the purposes of discussion of some of the embodiments of the present technology. Moreover, while the technology is amenable to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are described in detail below. The intention, however, is not to limit the technology to the particular embodiments described. On the contrary, the technology is intended to cover all modifications, equivalents, and alternatives falling within the scope of the technology as defined by the appended claims.
One or more embodiments of the present disclosure provide a rock tumbler apparatus. As will be discussed in more detail, the rock tumbler apparatus functions to smooth and polish irregularly shaped hard objects. The rock tumbler may be operably attached to a programming system, which may include a sound dampening cover. The rock tumbler may be programmed, for example, to tumble during certain times of day, continually, to pause at various time intervals, and to tumble in one direction or another.
Some embodiments include a scheduling feature that allows the tumbling action to be paused or activated during certain times of the day. For example, a user could program the rock tumbler to tumble during the day when people are out of the house. As another example, the user could program the rock tumbler to tumble at night when people are sleeping. Some embodiments use a barrel wheel having inner and outer walls with energy absorbing air gaps disposed therebetween. The air gaps serve to dampen sound waves from the crashing rocks inside the barrel to mitigate transmission of the sound waves to the rest of the tumbler base.
Some embodiments may use metal, plastic or foam rollers. The driving rollers may be made or lined with thick foam or rubber-like material in some embodiments. The rollers can also provide sound reduction as the sound waves from the barrel will be absorbed through the foam/rubber roller and not transmit to the rest of the tumbler base. In some embodiments a sound dampening cover may be present. Some embodiments may use a dual- or vacuum-sealed cover that will limit sound of the tumbler. In some embodiments, the cover may be a single wall cover, a dual wall cover, a dual wall cover that is vacuum-sealed, and/or other variation.
Some embodiments may operate in a continual mode that when the tumbler is paused or completed, it will tumble or tum the barrel a few revolutions at a certain time frequency (e.g., every 30 minutes). This can be beneficial if you leave a barrel full of rocks and water and grit over a long period of time (e.g., 3+ weeks) the water and grit will start to harden not unlike concrete. But having a continual movement can avoid that result. Some embodiments may also include an agitate mode that would cause the tumbler to spin in one direction for a short time (e.g., 0.5 seconds) and then switch to the opposite direction for equal time, and back again. This mode could be used for quieter tumbling (however it would take a lot longer), or used on softer rocks, or if you want to keep the rocks more whole during the process (normally the rocks will shard off and make smaller rocks during normal tumbling processing). This mode of operation may provide an overall sound that is quieter and more pleasant and could be used to tumble softer rocks. That would normally not work in traditional tumblers because they would become too small over time. Using this for all stages will take longer, but is quieter and gentler on tumbling. Thus, the user will get less rock fracturing, keeping your rocks larger than traditional tumbling.
Various embodiments of the present technology provide for a wide range of technical effects, advantages, and/or improvements. For example, various embodiments include one or more of the following technical effects, advantages, and/or improvements: 1) rock tumbler with multiple operating modes of operation; 2) integrated use of sound dampening features and operational modes to create a quieter rock tumbler; 3) use of unconventional and non-routine computer operations to allow for customized rock tumbling experience; and/or 4) dynamic user interface system allowing user to set operational modes and tumbling restrictions, as well as to provide a speaker with music or a noise cancelling microphone to further reduce noise.
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the present technology. It will be apparent, however, to one skilled in the art that embodiments of the present technology may be practiced without some of these specific details.

The sound dampening cover may be dual- or vacuum-sealable to limit the sound of the tumbler. As will be understood by one skilled in the art, the sound dampening cover may comprise, for example, one or more single panes of glass, polycarbonate, acrylic, or equivalent materials thereof.
In accordance with various embodiments, a variety of materials may be used for different parts of the tumbler. The materials may be selected based on a number of different factors (e.g., strength, durability, color, etc.). For example, in some embodiments, the materials for the cover may be clear, while in other embodiments the materials for the cover may be opaque (e.g., black). In addition, the sizes and shapes of various components may vary depending on the specific embodiment. For example, the size shape and configuration of the “tweel” ribs are noted. However, other configurations are possible including, but not limited to those shown in the Appendices. For example, in some embodiments, the shape of the ribs may be straight, V-shaped, waved, hexed, or the like with varying frequency patterns and rib thickness to those illustrated herein.
The following examples are provided to illustrate further the various applications of the present disclosure and are not intended to limit beyond the limitations set forth in the appended claims.
The rock tumbler as disclosed herein may be used to smooth and polish irregularly shaped hard objects, such as stones. A grinding medium, sometimes comprising an aqueous solution of water and an abrasive, may be added to the inner barrel, along with the irregularly shaped hard objects. As the rock tumbler is agitated or tumbles, the abrasive makes repeated contact with the hard objects and over time, smooths and polishes the objects. The programming unit 303 allows the user to schedule the rock tumbler to operate, for example, during a certain time of day or night.
In one example, the user may program the rock tumbler to operate in a continual mode. This is a mode that when the tumbler is paused or the program has completed, it will tumble or tum the barrel a few revolutions at a certain time frequency, for example, every 30 minutes. This prevents the composition inside the barrel, for example rocks, water, and grit, from hardening. As will be understood by one skilled in the art, the time frequency and length of tumbles or turns in this mode will vary depending on the composition inside the rock tumbler.
In another example, the user may program the rock tumbler to operate in an agitate mode. In this mode the rock tumbler would spin in one direction for a short period of time (example 0.5 second) and then switch to the opposite direction for equal time, and back again. This mode would provide quieter tumbling, and may be used on softer rocks, or to keep the rocks from breaking into smaller pieces during the tumbling process. Thus there is less rock fracturing, keeping the rocks larger than traditional rock tumbling.
