DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
For purposes of description herein, the terms “upper”, “lower”, “left”, “rear”, “right”, “front”, “vertical”, “horizontal”, and derivatives thereof shall relate to the invention as oriented in FIG. 2. However, one will understand that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
An exemplary embodiment of a fish scale removing rotary apparatus 100 is presented herein, best presented in FIGS. 1 and 2. The fish scale removing rotary apparatus 100 comprises two (2) primary components, a fish scale removing rotary handpiece 102 and a scale removing blade assembly 120. The fish scale removing rotary handpiece 102 is cylindrical in shape and of a size for one-handed use. The fish scale removing rotary handpiece 102 includes a rotary motor (not shown but well understood) and a power control switch such as a slide power control 106. The slide power control 106 utilizes a sliding switch. The slide control 106 generally includes a variable speed control provided via a detent respective to each optional predetermined speed setting. Another optional power control system can include a separate variable speed controller and an On-Off power switch (both are understood and well known for use on other applications, but not shown). The fish scale removing rotary handpiece 102 incorporates a blade coupling member 104 for removably coupling the scale removing blade assembly 120 to the motor of the fish scale removing rotary handpiece 102. The blade coupling member 104 can be a commonly known key chuck, a keyless chuck (as illustrated), a non-circular quick disconnect design, and the like. A scale removing blade shield 110 is preferably removably assembled to the fish scale removing rotary handpiece 102 providing protection to the user from the blades and any debris such as scales 142. The scale removing blade shield 110 is preferably of a transparent or translucent material and secured to the fish scale removing rotary handpiece 102 via a blade shield coupler 112. The blade shield coupler 112 is essentially a band clamp placed about the circumference of the fish scale removing rotary handpiece 102 and fastened via a shield coupler fastener 114. The exemplary embodiment of the scale removing blade shield 110 provides a protection apparatus about the upper half (non contacting side) of the scale removing blade assembly 120. The fish scale removing rotary apparatus 100 is designed to rotate the blade coupling member 104 at a rate ranging between 1,500 and 2,500 RPMs. The blade coupling member 104 can be coupled either directly or via a plurality of gears to the rotary motor. A scale removing edge 129 (FIG. 6) of the scale removing blade assembly 120 brushes against fish scales 142 of a scaly fish 140, thus removing the fish scales 142 from the scaly fish 140. The user passes the scale removing blade assembly 120 across the scaly fish 140 via a tool motion 132. The blade rotation 130 and the tool motion 132 are each preferably oriented counter the scale direction 144.
Details of the scale removing blade assembly 120 are presented in FIGS. 3 through 7. The scale removing blade assembly 120 is fabricated having a blade shaft 122 having a plurality of planar blade 124 disposed thereon. The preferred embodiment is a scaling blade assembly having four (4) planar blades 124 equally spaced about the blade shaft 122. For reference, the blade shaft 122 is defined as having a coupling end 126 and a distal end 128. The coupling end 126 can incorporate features such as a plurality of flat sections 123, a tab (not shown), and any other feature which defines a non-circular cross sectional shape of the blade shaft 122, thus aiding in the transfer of the applied torque from the blade coupling member 104 to the blade shaft 122. The torque causes the scale removing blade assembly 120 to move as described via a blade rotation 130. The blades 124 are of a rubber or other flexible material providing flexure during use. The blades 124 are of a dimension allowing the blades 124 to flex when rotating and contacting the fish scales 142. Friction and the flexure increase the efficiency of the scale removal process. Additionally, the blade design allows for increased rotational speed of the apparatus 100. The planar blade 124 flexes based upon several factors: the dimensions and the material. The material is non-rigid, such as rubber, nylon, plastic, dense cardboard, and the like. The blade 124 is of a width W that is significantly greater than the thickness T proximate the coupling end 126 of the blade assembly. A preferable length to width ratio would be between 2:1 and 4:1, but can easily be as great as 10:1. The greater the width W to thickness T ratio, the more flexure of the blade 124′ (FIG. 7) is achieved by geometry. The fish contacting surface is defined by a scale removing edge 129 and finished to avoid sharp edges, such as by chamfering, rounding, and the like as illustrated in FIG. 6. The contacting surface is continuous along the length L of the blade 124. The contacting surface can be linear or curved. The end of the blade 124 tapers towards the blade shaft 122 proximate the distal end 128 for safety.
The previously presented embodiments utilize batteries for power. Alternate power scenarios are presented in FIGS. 8 and 9. The fish scale removing rotary apparatus 100 can be powered by AC via an AC power connector 116 (FIG. 8) or by DC via a DC power connector 118 (FIG. 9). The plug 116, 118 is in electrical communication with rotary motor of fish scale removing rotary handpiece 102 via a power cord 108. A levered power control 107 is incorporated providing a trigger or levered style power control providing the user with a fixed (On-Off) or variable switch. The levered power control 107 requires that the operator continuously hold the switch for operation, providing an additional safety feature. The illustration presents an alternate scale removing blade assembly 150, being an alternate to the scale removing blade assembly 120 previously presented.
Details of the scale removing blade assembly 150 are presented in FIGS. 10 through 13. The scale removing blade assembly 150 is fabricated having a blade shaft 152 having a plurality of blades 154 disposed thereon. The blade 154 is similar to the blade 124, whereas the blade 154 provides a triangular shape, as opposed to the polygon shape of the blade 124. For reference, the blade shaft 152 is defined as having a coupling end 156 and a distal end 158. The coupling end 156 can incorporate features such as a plurality of flat sections 153, a tab (not shown), and any other feature providing the same benefits as the torque features of the coupling end 126 previously presented. The planar blade 154 comprising the same features and dimensions as presented respective to the blade 124 previously presented. The contacting surface is defined by a scale removing edge 159 and finished to avoid sharp edges, such as by chamfering, rounding, and the like as illustrated in FIG. 13. The contacting surface is continuous along the length L of the blade 154. The contacting surface can be linear, chamfered, or curved.
Details of an alternate exemplary scale removing blade assembly 160 are presented in FIGS. 14 through 17. The scale removing blade assembly 160 is fabricated having a blade shaft 162 having a plurality of blades 164 disposed thereon. The blade 164 is similar to the blade 124, whereas the blade 164 provides a rectangular shape having a curved distal end, as opposed to the polygon shape of the blade 124. For reference, the blade shaft 162 is defined as having a coupling end 166 and a distal end 168. The coupling end 166 can incorporate features such as a plurality of flat sections 163, a tab (not shown), and any other feature providing the same benefits as the torque features of the coupling end 126 previously presented. The planar blade 164 comprising the same features and dimensions as presented respective to the blade 124 previously presented. The contacting surface is defined by a scale removing edge 169 and finished to avoid sharp edges, such as by chamfering, rounding, and the like as illustrated in FIG. 17. The contacting surface is continuous along the length L of the blade 164. The contacting surface can be linear, chamfered, or curved.
