Abstract
Abstract A magnetic seam tracking device designed to orientate the feed or forward motion of a soldering tool along the edges of metal sheets disposed head against head and to be submitted to the soldering operaion. The device comprises a carriage or truck B capable of retaining the soldering tool A, said carriage or truck being provided with track-chains (30), the articulated elements whereof have permanent magnets (40-42) which co-operate with metal sheets (D1) and (D2) to be soldered.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
A magnetic crawler vehicle especially adapted for running soldering apparatus along a joint between metal members to be solder-joined, the vehicle being provided with member-engaging endless crawler track means, and means for driving the track means, said track means comprising: magnetic shoe units which have respective pairs of spaced generally coextensive magnetic pole plates; said shoe units being articulated in spaced relation in an endless chain disposed inwardly relative to said units and including links; respective permanent magnets fixed between the pole plates; said plates having traction shoe surfaces projecting beyond the respective magnets and operable in magnetic traction along said joint; and means pivotally connecting said links to the shoe units generally in the planes of said plates.
Claim 2
Dependent Claim
119 words
A magnetic crawler vehicle especially adapted for running soldering apparatus along a joint between metal members to be solder-joined, the vehicle being provided with member-engaging endless crawler track means, and means for driving the track means, said track means comprising: magnetic shoe units which have respective pairs of spaced generally coextensive magnetic pole plates; said shoe units being articulated in spaced relation in an endless chain disposed inwardly relative to said units and including links; respective permanent magnets fixed between the pole plates; said plates having traction shoe surfaces projecting beyond the respective magnets and operable in magnetic traction along said joint; and means pivotally connecting said links to the shoe units generally in the planes of said plates.
Claim 3
Dependent Claim
29 words
A magnetic crawler vehicle according to claim 1, wherein said shoe surfaces comprise edge portions of said plates of substantial length projecting in parallel relation beyond the respective magnets.
Claim 4
Dependent Claim
30 words
A magnetic crawler vehicle according to claim 1, including attachment plates secured to proximal portions of said pole plates, and said connecting means connecting said links to said attachment plates.
Claim 5
Dependent Claim
22 words
A magnetic crawler vehicle according to claim 3, wherein distal portions of said magnetic unit plates project substantially beyond the respective magnets.
Claim 6
Dependent Claim
16 words
A vehicle according to claim 3, including laterally extending guide surfaces structure on said attachment plates.
Claim 7
Dependent Claim
40 words
A magnetic crawler vehicle according to claim 1, wherein said plates have proximal portions which project beyond the respective magnets and distal portions projecting beyond the magnets and providing said traction surfaces, and means securing the plates to the magnets.
Claim 8
Dependent Claim
60 words
A magnetic crawler vehicle according to claim 1, including a frame providing support for the endless track means, guide structure on the track means, and adjustable guide means on the frame coacting with the guide structure on the track means for controlling orientation of the track means with respect to the profile of surface along which the track means travels.
Claim 9
Dependent Claim
133 words
A magnetic crawler vehicle especially adapted for running soldering apparatus along a joint between metal members to be solder-joined, the vehicle being provided with member-engaging endless crawler track means, and means for driving the track means, said track means comprising: articulated magnetic shoe units which have respective pairs of spaced generally coextensive magnetic pole plates; respective permanent magnets fixed between the pole plates; said plates having traction shoe surfaces projecting beyond the respective magnets and operable in magnetic traction along said joint; a frame providing support for the endless track means; guide structure on the track means; and adjustable guide means on the frame coacting with the guide structure on the track means for controlling orientation of the track means with respect to the profile of surface along which the track means travel.
Claim 10
Dependent Claim
133 words
A magnetic crawler vehicle especially adapted for running soldering apparatus along a joint between metal members to be solder-joined, the vehicle being provided with member-engaging endless crawler track means, and means for driving the track means, said track means comprising: articulated magnetic shoe units which have respective pairs of spaced generally coextensive magnetic pole plates; respective permanent magnets fixed between the pole plates; said plates having traction shoe surfaces projecting beyond the respective magnets and operable in magnetic traction along said joint; a frame providing support for the endless track means; guide structure on the track means; and adjustable guide means on the frame coacting with the guide structure on the track means for controlling orientation of the track means with respect to the profile of surface along which the track means travel.
Claim 11
Dependent Claim
44 words
