Abstract
Abstract A burner for metal coating by means of an electric arc in which the fusible arc electrodes rest against a stable support, against which they are pressed by first spring loaded chucks. Second spring loaded chucks act on the fusible arc electrodes close to the arc. In case of irregularities of the arc electrodes, maintain thus the arc at a constant place even if the arc electrodes are bent or of irregular thickness.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
An arrangement for guiding a pair of wire electrodes connected to driving means and electric terminals of a burner for metal coating by means of an electric arc comprising in combination: a burner body, an insulating guiding insert mounted in said burner body with guiding grooves for guiding said wire electrodes at an angle to each other, a pair of first spring loaded insulated chucks positioned to urge both wire electrodes against the guiding insert, a pair of second spring loaded insulated chucks close to the fusing ends of the wire electrodes, securing the correct position of the fusing ends of the electrodes, and stop means positioned to determine the initial position of said second chucks.
Claim 2
Dependent Claim
116 words
An arrangement for guiding a pair of wire electrodes connected to driving means and electric terminals of a burner for metal coating by means of an electric arc comprising in combination: a burner body, an insulating guiding insert mounted in said burner body with guiding grooves for guiding said wire electrodes at an angle to each other, a pair of first spring loaded insulated chucks positioned to urge both wire electrodes against the guiding insert, a pair of second spring loaded insulated chucks close to the fusing ends of the wire electrodes, securing the correct position of the fusing ends of the electrodes, and stop means positioned to determine the initial position of said second chucks.
Claim 3
Dependent Claim
204 words
An arrangement for guiding a pair of wire electrodes connected to driving means and electric terminals of a burner for metal coating by means of an electric arc comprising in combination: a burner body, an insulating guide insert mounted in said burner body and having guiding grooves for guiding said wire electrodes at an angle to each other, a plurality of bolts mounted in fixed positions Within said burner body, first and second pairs of insulated chucks pivotally mounted on said bolts, said chucks being positioned with each group of one first and one second chuck engageable with a separate electrode and the second chucks being closer to the fusing ends of said electrodes than said first chucks; a recess in each said chuck on the side thereof toward the other chuck of the same group of first and second chucks; spring means extending between the recesses of each group of first and second chucks, said recesses being spaced from the bolts on which the respective chucks are pivotally mounted whereby said spring means urges both chucks of each group of chucks into engagement with the respective wire electrode; and stop means positioned to limit the displacement of said second chucks toward said electrodes.
Claim 4
Dependent Claim
204 words
An arrangement for guiding a pair of wire electrodes connected to driving means and electric terminals of a burner for metal coating by means of an electric arc comprising in combination: a burner body, an insulating guide insert mounted in said burner body and having guiding grooves for guiding said wire electrodes at an angle to each other, a plurality of bolts mounted in fixed positions Within said burner body, first and second pairs of insulated chucks pivotally mounted on said bolts, said chucks being positioned with each group of one first and one second chuck engageable with a separate electrode and the second chucks being closer to the fusing ends of said electrodes than said first chucks; a recess in each said chuck on the side thereof toward the other chuck of the same group of first and second chucks; spring means extending between the recesses of each group of first and second chucks, said recesses being spaced from the bolts on which the respective chucks are pivotally mounted whereby said spring means urges both chucks of each group of chucks into engagement with the respective wire electrode; and stop means positioned to limit the displacement of said second chucks toward said electrodes.
Claim 5
Dependent Claim
59 words
The arrangement of claim 2 further comprising a covering nut pivotable on said burner body and having an aperture through which said electrodes are adapted to extend, said stop means comprising a bevelled surface on the inside of said cover nut, said second chucks being positioned to engage said surface to limit the displacement thereof toward said wire electrodes.
Claim 6
Dependent Claim
33 words
The arrangement of claim 2 further comprising a supporting piece mounted within said burner body, said bolt being mounted on said supporting piece, said guiding insert being centrally mounted on said supporting piece.
Claim 7
Dependent Claim
24 words
The arrangement of claim 4 further comprising a covering nut threaded on said burner body for holding said supporting piece within said burner body.
