The present invention relates generally to methods and means by which cuts, including approximately circular cuts, can be made in a vessel such as a plate metal or a metal sheet, and in a specific though non-limiting embodiment, to a plate burner system having improved performance characteristics relative to the circle burners presently known in the prior art.
Previously, circle burners have been limited in that there are well-understood, practical limits to the sizes and shapes of the cuts produced by the devices. For example, most known hand-tool type circle burners, which currently sell for around one hundred dollars, create only straight cuts of either nine inches or fifteen inches, and lack the capacity to bevel the boundary surface of the plate being modified. Moreover, the smallest diameter burn is only around two inches, and the device is fitted with a number of ball bearings in the tip head, which, when heated, tend to become fouled and impair the functionality of the device.
While commercial units are available to create beveled cuts, they are very large and bulky, and are also very expensive as compared to the hand tool variety. For example, a known circle burner capable of creating beveled cuts exists in which the apparatus is several feet tall and weighs between sixty-five pounds and one hundred pounds. The device currently sells for around two thousand dollars.
Accordingly, Applicant has invented a new and non-obvious hand tool that incorporates some of the beneficial features of the larger, stand-alone units, in a manner in which welders and other operators can quickly, easily and accurately cut plate steel, plate metal, metal sheet and the like, so that the resulting port is smooth around the edges, very nearly uniformly circular, and beveled using either an inside or outside cutting technique.
The invention at its core comprises an adjustable pivoting member and a cutting tip. In a presently preferred embodiment, however, the system includes both an adjustable torch stabilizer and an adjustable leveling member, so that the welder's torch is held steady, and the entire device is securely and reliably stabilized while cuts are being burned.
According to one example of the invention, there is provided a multipurpose plate burner system comprising: a shaft, whereby a beam is formed; at least one sleeve movably attached to the shaft, the sleeve having a receiving channel disposed offset from the shaft; an object disposed in the receiving channel, whereby the object is operable to position a contact location with a workpiece. The system further comprises: a torch head receptacle attached to the shaft; wherein an object disposed in the receiving channel is selected from the group comprising: a pivot, a pivot arm having an offset pivot point, a leveling wheel, a roller bearing leveler, a trammel point, a soapstone holder, a torch nozzle holder, a table support, a torch saddle, and a flat bottomed pin. Further, the torch head receptacle may be a torch-nozzle receiving orifice integrated on an end of the shaft, or may be a torch nozzle holder affixed to a sleeve movably attached to the shaft. The torch head receptacle is operable to be positioned a fixed distance from the workpiece.
In another example, the shaft is comprised of one or more beam sections further comprising means for fitting said beam sections together.
In another example, at least one sleeve comprises: a first channel for receiving the beam of the shaft; and a second channel disposed offset from the first channel for receiving at least one object. In another example, at least one sleeve comprises a first locking means for affixing the sleeve to a position on said shaft. In another example, at least one sleeve comprises a second locking means for affixing at least one object to the sleeve.
In another example, the second channel of at least one sleeve comprises a substantially circular opening, whereby an object inserted there through may freely rotate therein. In another example, the second channel of at least one sleeve is disposed substantially perpendicular to the first channel.
In another example, at least one sleeve further comprises: a third channel, for receiving at least one object, the third channel disposed offset from the first channel and opposite the second channel, the third channel having an axial orientation similar to the axial orientation of the second channel; and a third locking means for affixing an object to the sleeve. In a further example, the axial orientation of the second channel and the axial orientation of the third channel are approximately fifty-five degrees relative to the axial direction of the first channel.
In another example, the torch nozzle holder comprises: a first attachment arm, having a first end; a torch head arm, having a first end, disposed adjacent and parallel to the first attachment arm, the first end of the first attachment arm connected to the first end of the torch head arm; a second attachment arm, having a first end, disposed adjacent and parallel to the torch head arm, the first end of the torch head arm connected to the first end of the second attachment arm; and a torch head receptacle disposed on a second end of the torch head arm, the torch head receptacle having a torch receiving orifice positioned perpendicular to the length of the torch head arm. The first attachment arm and the torch head arm and the second attachment arm are coplanar with respect to the perpendicularly positioned torch-receiving orifice. Further, the length of the first attachment arm is less than the length of the second attachment arm.
In another set of examples of the present invention, there is provided a multipurpose plate burner system comprising: a means for positioning a burning apparatus over a workpiece; a means for remotely guiding the burning apparatus; a first means for pivoting the positioning means about a first axis of rotation; a second means for pivoting the positioning means about a second axis of rotation; and a means for stabilizing the burning apparatus over the workpiece.
In another example, the means for remotely guiding comprises a shaft. In a further example, the shaft is comprised of one or more beam-sections further comprising means for fitting the beam sections together
In another example, the means for positioning comprises at least one sleeve movably attached to the remote guiding means, the sleeve having a receiving channel disposed offset from the remote guiding means; and at least one object disposed in the receiving channel, whereby the object is operable to position a location of contact with the workpiece.
In another example, the first means for pivoting comprises: one sleeve wherein the receiving channel comprises a substantially circular opening, whereby an object inserted there through may freely rotate therein. The inserted object may be a pivot, or a pivot arm.
In another example, the second means for pivoting comprises: a pivot arm disposed in the receiving channel of one sleeve; and a pivot attached to the pivot arm. In further example, the second means for pivoting comprises: a pivot arm; and a pivot disposed on the pivot arm, the pivot arm disposed in the first means for pivoting.
In another example, the means for stabilizing the burning apparatus comprises at least one sleeve movably attached to the remote guiding means, the sleeve having a receiving channel disposed offset from the remote guiding means; and at least one object disposed in the receiving channel, whereby the object is operable to position a location of contact with the workpiece. In a further example, the means for stabilizing the burning apparatus comprises at least one sleeve movably attached to the remote guiding means, the sleeve further comprising a location of contact with the burning apparatus.
According to one example of the invention, there is provided a multipurpose plate burner system comprising: a shaft for deploying a burning apparatus over a workpiece; a support movably attached to the shaft, the support providing a selected distance between the shaft and the workpiece; and a torch head receptacle attached to the shaft, the torch head receptacle providing a selected distance between the burning apparatus and the workpiece.
In a further example, the support may be a fixed support. The support may be a pivotal support. The support may be a multiple pivotal support.
Various aspects of the invention, including alternative embodiments and the various functionalities associated therewith, are disclosed with particularity in the attached drawings,
As an example of the present invention, a multipurpose radius plate burner system is presented where a collection of components may be selected in combination to configure the system to achieve one of a selection of purposes. As illustrated in
In the corner burner configuration, this example of the present invention allows variable setting of hole radius without the need to change the length of the shaft. Further, guidance of the tool may be accomplished from a more convenient location, as the longer shaft can be used to control cutting of smaller diameter holes, such as in corners or underneath obstacles. The use of a roller bearing for a leveler, along with the offset afforded by the pivot arm, in this configuration provides necessary freedom of movement to accomplish this remote hole cutting capability.
As illustrated in
Sleeves of various configurations are illustrated in
Torch saddle 3, shown in
The angled torch head sleeve 5, shown in
Additional objects held by the sleeves, of various configurations, are illustrated in
In another example, the system may be configured as a protractor, typically by selecting an adjustable pivot with locking sleeve and a soapstone holder (or trammel point) with locking sleeve, all mounted on a shaft.
In another example, the system may be configured as a scribing device, typically by selecting an adjustable pivot with locking sleeve and a trammel point with locking sleeve, all mounted on a shaft.
In another example, the system may be configured as a track burner, typically by selecting a slidable ninety-degree or angled/beveling torch sleeve, and a shaft stabilizer with locking sleeve, both mounted on a shaft.
From the foregoing illustrated examples, it can be seen that other system configurations may be assembled from the described components. In one further example, the system may be configured to accommodate lengths exceeding approximately one arm span, approximately six feet or greater, typically by selecting a round pivot with locking sleeve, the round pivot spot-tacked to the workpiece, leveling wheel with locking sleeve, and torch head sleeve, all mounted on a shaft. The system may also be configured as a mini-burner, typically by selecting an adjustable pivot with locking sleeve, leveling wheel with locking sleeve, and a R.H./L.H. angled torch head sleeve, all mounted on a shortened, approximately one foot, shaft. The mini-burner configuration can accommodate the mini-burner torch size. In a still further examples, the tool system provided by the present invention burns ninety degree and bevels I.D. and O.D. on a radius. It also performs as a corner burner, burning a radius in a corner or under obstacles. As a track burner, it will burn a straight line at ninety degree or bevel, up to six feet long or as far as the shaft will permit. The tool system can also be used as trammel points or as a protractor. It can also be used as a mini-burner with application of a shorter shaft, still providing the ability to burn ninety degree and bevels. Thus, these examples of the present invention provide at least four burning tools, a mini-burner, a set of trammel points, and a protractor all in one tool system.
In the foregoing, the term ninety-degree as used in practice encompasses various degrees of tolerance and is to be applied as a term representing a substantially straight cut. The terms “burn”, “burner”, and “burning” are typically used in the subject art to describe the apparatus or act of cutting, marking, or depositing on, substances such as metal by the use of a heat source, such as a flame torch or electrical arc. It can be appreciated that the term “torch” may apply to heat sources such as a flame torch or arc.
The foregoing is provided for illustrative purposes only, and is not intended to describe all possible aspects of the present invention. Those of ordinary skill in the pertinent arts will appreciate that minor changes to the description, and various other modifications, omissions and additions can be made without departing from either the spirit or scope of the invention as claimed.
