Patent Application

The embodiments herein relate generally to table saws and other equipment used in woodworking applications such as the construction of cabinet drawers.
Table saws and other equipment such as routers used in woodworking are useful for cutting and/or shaping plywood to help a user to build finished products such as drawers, tables, shelves, other structures, or the like. Individuals may cut the plywood to a desired size, create a groove within the plywood and/or shape the plywood by creating a bullnose on an edge.
Several saw devices for use in woodworking are disclosed in U.S. Pat. Nos. 8,539,870, 8,746,668 and 4,445,412. These devices comprise at least one blade that is designed to cut a piece of plywood. However, these devices are limited because they do not permit a user to perform different woodworking tasks simultaneously such as cutting the plywood, creating a groove in the plywood and carving an edge to create a bullnose. Current woodworking devices and methods require a user to perform these different tasks separately with multiple pieces of equipment. This is inefficient and creates significant burdens on the user.
As such, there is a need in the industry for a multiple blade table saw with an adjustable router attachment that addresses the limitations of the prior art, which permits a user to perform different woodworking tasks at one time to improve efficiency in completing a project.
A multiple blade table saw for use with an adjustable tool attachment assembly is provided. The multiple blade table saw is configured to enable a user to perform different woodworking tasks simultaneously on plywood to enhance efficiency. The multiple blade table saw assembly comprises a housing configured to store a blade assembly comprising a plurality of blades operably connected to a motor, a tabletop coupled to a top of the housing and comprising a first slot and a second slot, the first slot configured to permit portions of the plurality of blades to extend therethrough to be exposed above the tabletop, and a carriage slidably mounted to the housing and configured to secure the tool attachment assembly thereto, the tool attachment assembly comprising a cutting member that is positioned within the second slot of the tabletop, wherein the carriage is slidably adjusted to place the cutting member at a desired location, wherein a user maneuvers a plywood sheet on the tabletop to permit the blade assembly and cutting member to cut the plywood sheet.
The detailed description of some embodiments of the invention will be made below with reference to the accompanying figures, wherein the figures disclose one or more embodiments of the present invention.
As depicted in
The multiple blade table saw comprises a housing with a plurality of supporting legs, tabletop 10, table plate 44, circular blade 26, a pair of dado blades 28, router 22 and router bullnose bit 24. Table plate 44 is disposed on top of the housing and tabletop 10 is placed on top of table plate 44. Tabletop 10 serves as a generally flat work surface and comprises blade slot 12 and router slot 14.
Router 22 comprises any type of router known in the field and is slidably mounted to the housing by router carriage 16, router bracket 18 and carriage rails 20. Specifically, router carriage 16 is slidably mounted to carriage rails 20, which are affixed to opposing sides of the housing. Router bracket 18 is coupled to an intermediate portion of router carriage 16 proximate router slot 14. Router 22 is disposed within an opening in router bracket 18 and is configured to receive a bit such as bullnose bit 24. Once the components are secured together, bullnose bit 24 is positioned within router slot 14. In this configuration, a user can slidably adjust router carriage 16 along carriage rails 20 to position bullnose bit 24 in a desired position anywhere within router slot 14. In one embodiment, a locking handle-type mechanism is used to secure router carriage 16 to carriage rails 20 in a stationary position once the desired position is achieved.
Circular blade 26, and dado blades 28 are operably connected to a motor (not shown) within the housing. Circular blade 26 is preferably a 10″ saw blade and each dado blade 28 is preferably an 8″ saw blade. However, alternative sized blades may be used instead. As depicted in
To operate the multiple blade table saw, a user slidably adjusts router carriage 16 to a desired position. Router carriage 16 is locked into place. In a preferred embodiment, router carriage 16 may be adjusted such that the distance between circular blade 26 and the side edge of router carriage 16 is anywhere between 3½″ to 15″. However, an alternative distance range may be permitted for adjustments. The motor is enabled to permit blades 26, 28 to rotate. Router 22 is enabled to permit router bullnose bit 24 to rotate. As depicted in
It shall be appreciated that the components of the multiple blade table saw described in several embodiments herein may comprise any alternative known materials in the field and be of any color, size and/or dimensions. Although the figures depict a router attached to the carriage, it shall be appreciated that alternative tools known in the field may be secured thereto instead. It shall be appreciated that the components of the multiple blade table saw described herein may be manufactured and assembled using any known techniques in the field.
Persons of ordinary skill in the art may appreciate that numerous design configurations may be possible to enjoy the functional benefits of the inventive systems. Thus, given the wide variety of configurations and arrangements of embodiments of the present invention the scope of the invention is reflected by the breadth of the claims below rather than narrowed by the embodiments described above.
