1. Detailed Description of the Figures

(12) Referring now to FIG. 1, a side view of the rock breaking attachment 10, according to the preferred embodiment of the present invention is disclosed. The rock breaking attachment 10 (herein also described as the “attachment”) 10, provides an attachment 10 for a hydraulic tamp 65 to assist in the breaking of obstructions 125, such as rock and other obstacles. The attachment 10 is provided in a desired embodiment (herein referred to as a first embodiment 15 and a second embodiment 20) perform fracturing and breaking of obstructions 125 such as rock, bedrock, concrete and other obstacles not normally penetrated by backhoes, shovels, picks and the like, but also where the use of a larger jack hammer is not feasible, warranted, or cost-effective

(13) The first embodiment 15 provides for a first main body 25 and a first cutting edge 30 that are in the overall shape reminiscent of a shark's tooth. Various first reinforcements 35 provide for structural strength and rigidity during use. A polymer bushing 40 provides a contact surface for attachment to the tamping foot 70 of the hydraulic tamp 65 as will be shown below. Two (2) clamp fasteners 45 allow for securement of the first embodiment 15. Further description of the operation of the clamp fasteners 45 will be shown herein below. It is envisioned that the first main body 25, the first cutting edge 30, and the first reinforcements 35 would be made of a high-grade silicon and/or boron steel.

(14) Referring next to FIG. 2, a side view of the attachment 10, according to the preferred embodiment of the present invention is depicted. The second embodiment 20 provides for a second main body 50 and a second cutting edge 55 that are in the overall shape reminiscent of a Philips screwdriver bit. Various second reinforcements 60 provide for structural strength and rigidity during use. As before, the polymer bushing 40 provides a contact surface for attachment to the tamping foot 70 of the hydraulic tamp 65 as will be shown below. The two (2) clamp fasteners 45 allow for securement of the second embodiment 20. Further description of the operation of the clamp fasteners 45 will be shown herein below. It is envisioned that the second main body 50, the second cutting edge 55, and the second reinforcements 60 would be made of a high-grade silicon and/or boron steel.

(15) Referring now to FIG. 3, an end view of the attachment 10, according to the first embodiment 15 of the present invention is shown. This view provides clarification on the first embodiment 15, the first cutting edge 30 and its symmetrical arrangement with the first main body 25 and the first reinforcements 35, providing the general appearance of a shark's tooth. The outer portion of the clamp fasteners 45 remain visible.

(16) Referring next to FIG. 4, an end view of the attachment 10, according to the preferred embodiment of the present invention is disclosed. This view provides clarification on the second embodiment 20, the second cutting edge 55 and its symmetrical arrangement with the second main body 50 and the second reinforcements 60, providing the general appearance of a Philips screwdriver when viewed from the end. The outer portion of the clamp fasteners 45 remain visible.

(17) Referring now to FIG. 5, a perspective view of the attachment 10 installed on a hydraulic tamp 65 according to the first embodiment of the present invention is depicted. The hydraulic tamp 65 is typical in nature and provides for a tamping foot 70, a reciprocating mechanism 75, a shaft handle 80 and connection hoses 85. The tamping foot 70 is provided with a downward facing curved shape, reminiscent to the shape of a kidney bean. The first embodiment 15 is mechanically coupled to friction fit by the two (2) clamp fasteners 45. It is noted that the attachment method for the second embodiment 20 (as shown in FIG. 2 and FIG. 4) is identical in nature to that shown here.

(18) Referring next to FIG. 6, a side view of the attachment 10, as seen along a line I-I, as shown in FIG. 5; according to the first embodiment 15 of the present invention is shown. The first embodiment 15, including the first main body 25 and the first cutting edge 30 is coupled against the polymer bushing 40 and the tamping foot 70 and secured with the two (2) clamp fasteners 45 (of which only one (1) is shown due to illustrative limitations. The clamp fasteners 45 have a main clamp body 90 which extends over the top of the tamping foot 70 and is secured on the distal side of the polymer bushing 40 with a first securing brace 95 via an auxiliary brace 100. A finger snap clamp 105 locks the auxiliary brace 100 to the first securing brace 100 using a snap hinge 108 with spring pressure. The opposite side of the of the main clamp body 90 is provided with a second securing brace 110 connected through a pivot fastener 115 on the top and a fixed block 118 on the bottom. This arrangement allows for firm and locking securement of the first embodiment 15 or the second embodiment 20 (as shown in FIG. 2 and FIG. 4) without the use of tools in a quick and secure manner. With the first embodiment 15 and the second embodiment 20 removed, the tamping foot 70 can be quickly returned to use as a conventional tamp with no permanent modifications.

(19) Referring to FIG. 7, a perspective view of the attachment 10, shown in a utilized state, according to the second embodiment 20 of the present invention is disclosed. A user 120 operates a hydraulic tamp 65 with the second embodiment 20 attached to the tamping foot 70 via the clamp fasteners 45. The second embodiment 20 is placed against an obstruction 125 such as a rock, boulder, or the like in the way of an excavation, drilled hole, trench or the like in the grade 130. After several blows from the above described process, the obstruction 125 will be shattered into smaller pieces that can be more easily moved by shovels, excavators, powered equipment, drilling rigs, or the like.

2. Operation of the Preferred Embodiment

(20) The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. It is envisioned that the attachment 10 would be constructed in general accordance with FIG. 1 through FIG. 5. The user 120 would procure either embodiment 15, 20 of the attachment 10 from conventional procurement channels such as industrial supply houses, construction equipment suppliers, mechanical supply houses, mail order and internet supply houses and the like.

(21) After procurement and prior to utilization, either the first embodiment 15 or the second embodiment 20 would be chosen based upon the specific need; the second embodiment 20 would provide for a more concentrated impact for use in breaking larger and more resilient obstructions 125; the first embodiment 15 would provide for shaping and removing obstructions 125 such as bedrock, concrete and the like, where portions of the underground obstruction 125 would remain behind and openings or channels would be made; the polymer bushing 40 would be placed against the tamping foot 70; the main clamp body 90 would be hooked over the first securing brace 95; and the finger snap clamp 105 would be pushed downward for both clamp fasteners 45. At this point in time, the attachment 10 is ready for use.

(22) During utilization of the attachment 10, the following procedure would be initiated: the first cutting edge 30 of the first embodiment 15 or the second cutting edge 55 of the second embodiment 20 would be placed against the obstruction 125; the hydraulic tamp 65 would be operated for a period of time until the obstruction 125 is broken or cleared.

(23) After use of the attachment 10, the first embodiment 15 or the second embodiment 20 can be removed by disconnecting the two (2) clamp fasteners 45 by reversing the above described process to allow use of the hydraulic tamp 65 in a conventional manner.

(24) The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.
