BACKGROUND OF THE INVENTION

This invention relates generally to the field of mechanical devices for polishing purposes and more specifically to a machine for polishing submerged surfaces, i.e. a pool.

Polishing procedures are based on friction of abrasive material between the polished surface and an auxiliary surface that can be the supportive media for the abrasive materials. The abrasive material is always harder than the surface to be polished and the auxiliary surface must be resistant to the abrasive material. As a general rule, the size of the grain of the abrasive material would dictate the polishing effect.

At first the process was a manual one involving a hand tool to apply the polishing material against the surface to be polished. Later on the abrasive material was glued to a hard surface creating in this way a polishing tool that required no abrasive material to operate. The limitation was that in time the tool would be worn out of the glued or fixed abrasive material reducing first the efficiency and then the utility of the same.

A new improvement was to fix the abrasive material to flexible surfaces such as paper or cloth allowing it to be used on its own or attached to a tool. In this way the tool becomes reusable with new abrasive attachments.

The next step was to design and produce hand tools powered by an external source, mainly electrical power but also pneumatically operated.

The invention introduces the hydraulic power to operate these polishing devices.

Rotating abrasive polishing tools are widely used in the industry but some limitations apply to their use on submerged surfaces. The first and most important is the nature of the power for the tool. Electric power makes it unsafe to operate under water, specially salt water. Pneumatic power can be used but introduces the problem of bubbles which cannot be avoided and must be diverted.

The limitations in the present technology specially for submerged surfaces can be overcomed by this invention.

BRIEF SUMMARY OF THE INVENTION

The primary object of the invention is that it is a hand held device.

Another object of the invention is to use hydraulic power.

Another object of the invention is that it operates both submerged and non submerged.

Another object of the invention is that is powered by pressurized water, i.e. by a pressure cleaning pump.

A further object of the invention is to allow exchangeable polishing disks.

Yet another object of the invention is that it does not overload the pressure pump.

Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

In accordance with a preferred embodiment of the invention, there is disclosed a machine for polishing submerged surfaces, i.e. a pool comprising: hydraulic power, only one rotating element, a two part casing, a pressure connector, and standard commercial polishing disks.

BRIEF DESCRIPTION OF THE DRAWINGS

The drawings constitute a part of this specification and include exemplary embodiments to the invention, which may be embodied in various forms. It is to be understood that in some instances various aspects of the invention may be shown exaggerated or enlarged to facilitate an understanding of the invention.

FIG. 1 is a perspective view of the invention showing the external casing indicated 1a in which the channel 1b has been prepared to allow the pressurized water into the machine. Reference 1c indicates the rotating axle to which the may be attached.

FIG. 2 is a perspective view of the invention from the bottom. Reference 2a indicates the external casing. The bottom closing of the machine is indicated 2b and the rotating axle referenced 2c goes through it to transmit the motion to the rotating disks. Reference 2d indicates the outlets for water that has already circulated through the turbine.

FIG. 3 is a perspective view of the invention in which the external casing has been removed to show the disposition of the turbine and it's attachment to the rotating axle. Reference 3a represents the turbine while reference 3b indicates the bottom closing of the machine through which the rotating axle indicated 3c transfers motion to the disks.

FIG. 4 is a top view of a section of the invention perpendicular to the rotating axle and through the turbine. Reference 4a indicates the external casing. The rotating axle is referenced by 4b and is attached to the turbine indicated 4c. References 4d indicate the outlets for water that has already circulated through the turbine. The channel indicated 4e allows the pressurized water to enter the turbine as indicated by the arrow 4f.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

A machine comprising a two part casing enclosing a low speed hydraulic turbine fixed to the only rotating axle. This axle rotates by means of the motion generated by the turbine while receiving the pressurized water injected through the pressure connector. Attached to the termination of the axle is a fixed disk that allows the attachment of the abrasive material disks.

The incoming pressurized water forces the turbine to rotate with the axle generating the rotary motion of the disk. The water is then discharged at low pressure towards the rotating disk.

The abrasive disks can be changed in accordance to the surface and polishing needs and standard commercial abrasive elements can be used. The machine can be used on submerged surfaces i. e. a pool.

While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
