Kits and methods for installing a light source on a tool rest

Abstract

A kit and method for installing a light source onto a lathe tool rest for improving the illumination of the workpiece is described. The kit includes a rectangular array of two or more LED light sources on a front side of a strip and a power source comprising a cord having one end connected to a rear side of the strip. Methods for installing the kit may include drilling a hole through a tool rest so that the cord extends through the rear side to avoid obstructing the lathe.

DETAILED DESCRIPTION OF THE INVENTION

(12) In the following description, terms such as horizontal, upright, vertical, above, below, beneath, and the like, are used solely for the purpose of clarity in illustrating the invention, and should not be taken as words of limitation. The drawings are for the purpose of illustrating the invention and are not intended to be to scale.

(13) Numerous tool rest designs are used with lathes depending on the work to be performed. It will be understood that the present invention is applicable to all tool rest configurations, the only requirement being that the tool rest includes a front surface upon which an LED light source large enough to provide the desired illumination can be mounted. The tool rest may be sold as new equipment or as a retrofit to existing lathes. The lighting source may be sold pre-installed on a tool rest, or may be sold as a retrofit kit that can be installed on a tool rest already owned by a user.

(14) The accompanying drawings are intended to illustrate two tool rest designs upon which the LED strip is attached. It will be understood that the shape of the tool rest is not critical to the invention, and that the light strip can be attached to the front surface of a wide variety of tool rests.

(15) FIGS. 1-3 illustrate a first type of tool rest, generally 10, comprised of a straight tool rest arm 12 supported on post 14. FIGS. 1 and 2 illustrate modification of this type of tool rest by attachment of LED strip 16 within horizontal recess 18. Alternatively, strip 16 can be mounted on the front surface of arm 12 as shown in FIG. 3. Strip 16 can be attached to arm 12 by various known means, such as fasteners, but will normally be attached with adhesive. Preferably, strip 16 extends substantially the width of arm 12. It will be understood, however, that a shorter LED strip is also contemplated. Strip 16 is connected to an electrical power source, not shown, by wire 20.

(16) FIGS. 4-5 illustrate another tool rest, generally 30, having a curved arm 32 with a round cross-section mounted on post 34. LED strip 36 is mounted within recess 38 and connected to an electrical power source via wire 40.

(17) FIG. 6 illustrates tool rest 10 mounted on a wood lathe, generally 50. Lathe 50 includes a bed 52, a headstock 54, a tailstock 56, and a saddle or banjo 58.

(18) FIG. 7 illustrates one embodiment of a kit 60 that can be used to install an LED light strip 62 onto a tool rest. LED light strip 62 is a generally rectangular array of one or more LEDs, and may be flexible to accommodate a variety of tool rest shapes. LED light strip 62 may be mounted on the front side of a tool rest by any number of means, including fastening the strip onto the tool rest using a bolt or strap. As depicted in FIG. 7, LED light strip 62 includes an adhesive backing 66 to adhere onto the front side of a tool rest.

(19) The kit 60 also includes a cord 64 used to supply power to LED light strip 62. Cord 64 is preferably placed on the rear of LED light strip 62. As shown in FIG. 7, cord 64 is located centrally in relation to LED light strip 62. Yet in other embodiments, cord 64 may be located away from the center of LED light strip 62. Alternatively, cord 64 may be found on an end of LED light strip 62, such as the left or right sides.

(20) In some embodiments, cord 64 may be a unitary item affixed to LED light strip 62 at one end and having a power plug at the opposing end. In yet other embodiments, however, cord 64 is a two-unit cord with a male connector and female receiver. Two-unit cords may be useful to eliminate a portion of the cord when light is not needed and for easier storage when LED light strip 62 is not in use. Cord 64 may comprise additional units depending on the number of components used for the power source. For instance, the kit may further include a transformer or other power supply 68. Cord 64 may be integrally affixed or separately detachable from power supply 68.

(21) Power supply 68 may be a low voltage transformer that decreases the supply voltage coming from the power outlet to LED light strip 62 when LED light strip 62 uses a low voltage circuit. For example, the kit may include a 12 volt LED light strip 62 with an accompanying low voltage transformer.

(22) In the embodiment shown in FIG. 7, the kit includes a cord 64 with a transformer 68 and a coaxial power connector having a first portion 70 and a second portion 72. First portion 70 is attached to the strip at one end and has a male connector 71 at its opposing end. Second portion 72 includes a female receiver 73 at one end adapted to receive male connector 71. The other end of second portion 72 is connected to transformer 68. Transformer 68 connects to cord 64 having a power plug 74 at the opposing end to be received by a power socket. Cord 64 supplies power to LED light strip 62 once the power plug 74 is connected to a power socket and female receiver 73 is connected to male connector 71. Transformer 68 may further include an on/off switch 69 for LED light strip 62. When not in use, male connector 71 can be disconnected to female receiver 73 so that second portion 72 and other components may be stowed away.

(23) Other embodiments of cord 64 and transformer 68 may include detachable unitary cords such as an AC adapter or multiple component cords such as an AC adapter including a power brick, and are not limited to the examples disclosed above. FIG. 7 shows first portion 70 soldered onto a center tapped LED light strip 62. However, cord 64 may be installed onto LED light strip 62 using any number of means, including plugging into a connector on the LED strip.

(24) FIGS. 8A and 8B illustrate a tool rest 80 adapted for installing a kit as described above. Tool rest 80 comprises a horizontal tool arm 82 attached to the upper end of a vertical support member 84. As shown in FIG. 8A, the front side of horizontal tool arm 82 may include a recess 86 to mount LED light strip 62. When installing the kit, a user may be instructed to drill a hole 90 through horizontal tool arm 82. Hole 90 allows cord 64 to pass through so that cord 64 extends from the back side of tool rest 80 to avoid obstructing the lathe or tool rest while in operation. Although hole 90 is shown at the intersection of horizontal tool arm 82 and vertical support member 84, hole 90 may be placed anywhere along horizontal tool arm 82 depending on where cord 64 is connected to LED light strip 62 or how tool rest 80 is shaped. A user may also be instructed to drill niche 92 to create additional space for the power components.

(25) FIG. 8B shows a close-up view of hole 90 from the rear side of tool rest 80. In this embodiment, the user is instructed to use a larger drill bit to create a countersink in the form of an optional recess 94 of a suggested depth to receive the female receiver 73 of second portion 72. This provides a slight ridge 96 inside the bore of the hole 90 to act as a stop that prevents pushing male connector 71 through the hole when plugging in female receiver 73 into the tool rest 80.

(26) FIG. 9A shows tool rest 80 with LED light strip 62 installed on the front side of horizontal tool arm 82. FIG. 9B shows the rear side of tool rest 80, where male connector 71 is seen protruding out of hole 90. Preferably, a sealing compound is applied around the connector 71 to hold it in place within the recess 94.

(27) The kit can be installed in other ways, as well. For example, instead of a hole through the tool rest, a groove or notch can be cut to fit the power cord. Clips can be added to retain the power cord in place on the tool rest.

(28) Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. By way of example, other types of light sources may be mounted onto the front side of the tool rest. Also, the size and shape of the tool rest may dictate whether a hole is needed to prevent cord obstruction, and where the hole should ideally be located. The overall size and shape of the hole may also depend on the type of power cord used with the kit. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
