TORCH SUPPORT AND GUIDE APPARATUS, METHOD OF USING SAME, AND KIT FOR CONSTRUCTING SAME

Abstract

A torch support and guide apparatus for a plasma cutting torch, for assisting a user in beveling workpiece edges and in sectioning workpieces. The apparatus includes a main support body having a base plate and a pair of support arms extending upwardly from the base plate, the arms configured to support a handle therebetween. The base plate has a cutout notch formed therein to accommodate a clamp subassembly which includes a U-shaped swing member and a clamping bracket. The base plate has a substantially rectangular shape, and has a horizontally extending groove formed in an upper surface thereof. The apparatus also includes a fence with a guide portion and a slide arm integrally attached to the guide portion. The slide arm of the fence fits slidably in the groove of the base plate. A kit for constructing the apparatus and a method of using the apparatus are also disclosed.

Description

Claims

1. A torch support and guide apparatus for use with a plasma cutting torch, the apparatus comprising: a main support body comprising: a base plate having a substantially rectangular shape with a cutout opening formed therein at a first edge portion thereof, the base plate having a horizontally extending groove formed in an upper surface thereof, the groove extending substantially parallel to a second edge portion of the base plate, the base plate further having a threaded bore extending therethrough proximate a portion of the groove;a pair of integrally formed support arms extending upwardly from the base plate and configured to support a handle therebetween, each of the support arms having a vertically extending slot formed therethrough;a handle which extends between and connects the support arms;a pivotally adjustable clamp subassembly disposed between the support arms, the clamp subassembly comprising: a substantially U-shaped swing member having a panel portion with a notch formed therein and two upwardly extending flanges on opposite ends thereof, at least part of the swing member fitting in the cutout opening of the base plate, each of the flanges of the swing member attached to one of the support arms by a fastener at the vertically extending slot thereof so as to permit both vertical and pivotal adjustment of the swing member by selectively adjusting the fasteners;a clamping bracket adjustably attached to the front end of the swing member at a side edge of the panel portion, the clamping bracket provided for selectively clamping a working end of the plasma cutting torch to the swing member;a fence having a guide portion with an L-shaped cross section, and a slide arm integrally attached to the guide portion and having a horizontally extending slot formed therethrough, the slide arm fitting slidably in the groove of the base plate, anda threaded fastener adjustably attaching the slide arm to the base plate by passing through the slot of the slide arm and into the threaded bore of the base plate.

2. The torch support and guide apparatus of claim 1, wherein the base plate has a plurality of openings formed in a lower surface thereof, each of the openings receiving a roller bearing therein.

3. A kit usable for constructing a torch support and guide apparatus, the kit comprising: a main support body comprising a base plate and a pair of integrally formed support arms extending upwardly from the base plate,the base plate having a substantially rectangular shape with a cutout opening formed in a first edge portion thereof, and having a horizontally extending groove formed in an upper surface thereof, the groove extending substantially parallel to a second edge portion of the base plate which is perpendicular to the first edge portion, the base plate further having a threaded bore extending therethrough at a portion of the groove;the support arms configured to support a handle therebetween, each of the support arms having a vertically extending slot formed therethrough;a handle which fits between the support arms of the main support body;a substantially U-shaped swing member having a panel portion with a notch formed therein and two upwardly extending flanges on opposite ends thereof, at least part of the swing member fitting in the cutout opening of the base plate, each of the flanges of the swing member attachable to one of the support arms at the vertically extending slot in a manner to permit both vertical and pivotal adjustment of the swing member;a clamping bracket attachable to the front end of the swing member on opposite sides of the notch, the clamping bracket provided for selectively clamping a working end of the plasma cutting torch to the swing member; anda fence having a guide portion with an L-shaped cross section, and a slide arm integrally attached to the guide portion and having a horizontally extending slot formed therethrough, the slide arm fitting slidably in the groove of the base plate.

4. A method of cutting a workpiece using a plasma cutting torch and a torch support and guide apparatus, said method comprising the steps of: clamping a cutting head of a plasma cutting torch in a clamp member of a torch support and guide apparatus;adjusting a position of the clamp member for both a height and an angular orientation on the torch support and guide apparatus;contacting an edge portion of the workpiece with a fence portion of the torch support and guide apparatus;energizing the plasma cutting torch; andmoving either the workpiece or the torch support and guide apparatus, with the energized torch attached, to make the desired cut.
