DETAILED DESCRIPTION OF THE INVENTION

Various embodiments of the invention are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without parting from the spirit and scope of the invention.

The present invention comprises several embodiments including, but not limited to, a compressed brick, a system for generating a compressed brick, an operating system for controlling a machine to compress brick, and a method of generating a compressed brick.

The '675 patent incorporated above discloses and claims an orthogonal breech, a press foot, a feed drawer, and a bucking foot and a surface coplanar with the feed drawer open lower end. The feed drawers as shown in FIG. 12 each require a hinged wall 41 following the fixed wall with a lower edge for screeding along the breech open upper end during the rearward motion of the feed drawer and for clearing above the three dimensional surface of the press foot during forward motion of the feed drawer. FIG. 12 of the '675 patent shows the hinge 42 and the hinged wall 41. They also include a roller 47 which enables the hinged wall 41 to pivot towards the inner part of the feed drawer when the feed drawer is moved into registration with the breech.

The present inventor has improved upon the prior art by removing the hinged wall and replace it with a flexible wall such as a nylon wall, rubber wall, a wall having bristles like a broom, or any other kind of flexible material. It is preferably that the new wall be attached to the fixed wall 39 (see FIGS. 12 and 13 of the '675 patent). This may be done via any structure such as screws, glue, spot welding, or any other known method of fixing the new wall to wall 39. In another preferred embodiment, the wall is fixed and has a notch at the bottom. This configuration is shown in FIG. 5 of the '675 patent.

Generally, the figures referenced next will be those in the present application. FIG. 1-3 provide some details regarding the overall structure of compressed brick machines according to the invention. Further details will be described in the following information. For example, the tongue may be different shapes such as curved or jagged, or so forth. Preferably, the tongue 402 on the deck, lower press plate tongue 604A and the notch in the tray 502 showed to be mirror images or be able to integrate with each other. The tray matches the tongue so that when the soil comes out, it only comes out to a certain point, the slide tray comes out to that point and on the next cycle, the lower plate shifts down and the soil tray would track and it doesn't leave any debris, so the preferred embodiment does not need to sweep because the bottom plate has been lowered so there is no reason to screed across the plate. The lower plate is then lowered and ready to fill up again with the soil mixture.

FIG. 4C illustrates the wall 39 with a flexible wall 100 also shown in a flexed position 102. In this configuration, as the feed drawer (not shown) is moved into position over the breech, the lower edge 102A of the flexible wall 100 strikes the three dimensional portions of the upper face of the press foot 20. The wall 102 flexes rearwardly so that the lower edge of the wall 102 rides on the uppermost portion of the press foot. When the feed drawer 30 is withdrawn to registration with the hopper 60, the rearward motion of the feed drawer 30 together with the excess material in the feed drawer 30 causes the flexible wall 100 to return to its normal vertical position to screed along the planar surface during withdrawal. Because the wall 100 is flexible, as it returns back over the press foot, if the press foot is a little high, the wall will flex rather than break as it engages with the press foot. The flexible wall provides an aspect of the present invention.

Another embodiment of the invention does not need to use the flexible wall. A preferred embodiment of the invention is shown in FIGS. 4A and 4B. These figures show a compressed brick machine having a deck 404, a tongue 402 and a completed compressed brick 408. The compression chamber where the compression of soils occurs to make the brick is shown as chamber 412. Hydraulics 414, 410 or some other type of mechanism may be used to raise and lower plates for compression. A control system 416 is manipulated by an operator.

The preferred embodiment of the invention simplifies the feeder tray such that it does not need a hinged plate. An example feeder tray 502 is shown in FIG. 5 having a groove 504 that mirrors the shape of the tongue 402. The tray 502 preferably does not have a bottom surface such that as it moves over a compression chamber when a lower plate is down, the soil will drop down into the chamber, as will be shown below.

FIGS. 6A-6E show the cycle. In FIG. 6A, the feeder tray 502 is positioned over a hopper (not shown) such that new soil 602 can be introduced into the tray 502. A compressed block from a previous cycle is shown 408. A lower plate 604 includes a tongue 604A that matches tongue 402 such that when it is elevated, the deck 404 and tongue 402 continue with the same surface arrangement as corresponding surfaces in the lower plate 604 and tongue 604A. FIG. 6B shows the tray 502 pushing to the left and forcing block 408 to the left and onto the deck 404. Because the wall and notch 504 of the tray 502 match the deck 404 and tongue 402 surfaces as well as the lower plate 604 and tongue 604A, and because the compressed brick also has a groove along its lower surface that is shown in FIG. 4A, as the tray 502 pushes the block to the left, tongue 402 prevents soil 602 from being pushed out onto the deck 404. In this regard, there is no need for the hinged wall of the prior art, thus simplifying the design and down-time of the machine.

FIG. 6C shows the lower plate 604 dropping into a lower position with the soil 602 dropping as well. This moves the soil into a compression chamber position. See FIG. 4B412. The tray 502 then retreats back to the right. FIG. 6D shows the top compression plate 606 coming down to complete the compression chamber and to compress the soil 602 into a brick 408. FIG. 6E shows the lower plate 604 raising to position the compressed brick 408 into a position where the tray 502 having a new supply of soil 608 can push the compressed brick 408 out onto the deck 404 while simultaneously providing new soil for the next block.

The feeder tray 502 is a simple tray—there is no need for a baffle on top of the feeder tray as is in the prior art patents for attaching a hinge. In the prior art, there is no tongue on the deck, so when the bottom plate is up and the block is being pushed out, the tongue on the lower plate is above the flat, planar deck. Thus the prior art needed the sweep to bring the soil back off the deck. With the preferred embodiment, without the tongue on the deck, a trail of soil would be left and need to be brought back. With the modification disclosed herein, the soil 602 does not escape onto the deck 404 as a block 408 is pushed from the chamber.

The method aspect of the invention is shown in FIG. 7 which shows comprises receiving soil into a tray having a first wall with a notch (702), the tray being at a first position, moving the tray into a second position wherein moving the tray causes a first compressed brick to be pushed onto a deck having a tongue that integrates with a groove in the brick (704), lowering a lower plate to create a portion of a compression chamber that receives the soil (706), lowering a compression plate in a vertical position over the lower plate to create a compression chamber (708), compressing the soil in the compression chamber to create a second compression brick (710), raising the compression plate (712), and raising the lower plate to lift the second compressed brick into a level position with the deck (714).

There are advantages to this approach. As has been discussed, the design of the compressed block system requires a person to shovel the sand and cement mixture into a feeder bucket that delivers the mixture to the feed drawer. That feeder bucket is elevated in the air. By lowering the compression plate, there will not be as much movement in the pressing foot or lower plate since it is no longer raised to a third level for compression, the X-axis movement of the feed drawer may be lowered and thus the feeder bucket into which the mixture is shoveled may be lowered. Therefore, there are several advantages to lowering the bucking foot into the compression chamber to compress the soil mixture.

The system operating according to the principles of the invention will have a known engine, controls and hydraulic system to complete the steps and structure described herein. Examples of such features are shown in FIGS. 4A and 4B.

The system preferably uses proximity switches, and it can be called a bucking cylinder. The height of the compressed brick is adjustable if one wants to make brick or pavers by changing how much compression is done. Preferably, the bricks are 4 inches tall by 8 inches wide by 12 inches deep. Those of skill in the art will understand the basic control mechanisms for the moderation and for compression. A control system 416 utilizes known as basic features to control a hydraulic or other network to move the various components such as the compression plate, lower plate, the tray and so forth. Furthermore, typically the control system will receive input from a human operator to either initialize the movement of various plates and tray according the steps set forth herein or in a manual fashion according to the capabilities and programming of the control system. The control system 316 includes various modules programmed according to principles known to those of skill in the art. The various modules will manage both the interaction of an operator with the system such as to receive input from the user as well as to control the hydraulics or the other types of systems within a compressed brick system to manage and control the various functions in order to compress brick according to the principles in the invention. For example, various modules will be programmed to control the movement of tray 502 in a preferable horizontal left and right movement into a first position and a second position. A module will be configured to manage the up and down movement of a top compression plate into its appropriate positions. Further a module will be configured to control the movement of the lower plate into its various positions so that it can receive soil and with the top compression plate create a compression chamber for compressing the brick and in connection with the horizontal movement of the tray 502 being able to raise the compressed brick into the appropriate position to be pushed out onto the deck 404.

Embodiments within the scope of the present invention may also include computer-readable media for carrying or having computer-executable instructions or data structures stored thereon. Such computer-readable media can be any available media that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to carry or store desired program code means in the form of computer-executable instructions or data structures. When information is transferred or provided over a network or another communications connection (either hardwired, wireless, or combination thereof) to a computer, the computer properly views the connection as a computer-readable medium. Thus, any such connection is properly termed a computer-readable medium. Combinations of the above should also be included within the scope of the computer-readable media.

Computer-executable instructions include, for example, instructions and data which cause a general purpose computer, special purpose computer, or special purpose processing device to perform a certain function or group of functions. Computer-executable instructions also include program modules that are executed by computers in stand-alone or network environments. Generally, program modules include routines, programs, objects, components, and data structures, etc. that perform particular tasks or implement particular abstract data types. Computer-executable instructions, associated data structures, and program modules represent examples of the program code means for executing steps of the methods disclosed herein. The particular sequence of such executable instructions or associated data structures represents examples of corresponding acts for implementing the functions described in such steps.

Those of skill in the art will appreciate that other embodiments of the invention may be practiced in network computing environments with many types of computer system configurations, including personal computers, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, network PCs, minicomputers, mainframe computers, and the like. Embodiments may also be practiced in distributed computing environments where tasks are performed by local and remote processing devices that are linked (either by hardwired links, wireless links, or by a combination thereof) through a communications network. In a distributed computing environment, program modules may be located in both local and remote memory storage devices.

Although the above description may contain specific details, they should not be construed as limiting the claims in any way. Other configurations of the described embodiments of the invention are part of the scope of this invention. For example, the control system of the machine may be operated manually or automatically via computer controls. A computer may be programmed with sensors to handle the operation and function of the machine as set forth above, wherein a user may only have to monitor the machine as it cycles through to create compressed bricks. Accordingly, the appended claims and their legal equivalents should only define the invention, rather than any specific examples given.
