Abstract
Abstract A gas cutting device for severing horizontally delivered material, comprising a longitudinal carriage travelling with the material to be cut, and a transverse carriage carrying clamping means and cutting burners, the transverse carriage being supported by bearing balls, the lower ball races of which are mounted upon transverse members extending over the track width of the longitudinal carriage, and the upper ball races being arranged on the transverse carriage, and at least either the upper ball races or the lower ball races being plane and comparatively broad.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A gas cutting device for severing horizontally delivered material, comprising: a longitudinal carriage capable of travelling at the speed of delivery of the material to be severed on a track extending in the direction of delivery, a transverse carriage supported upon the longitudinal carriage, clamping levers for gripping the material to be severed and burners for cutting it, carried by the transversely movable carriage, crossbars forming part of the longitudinal carriage and extending over the track width of the longitudinal carriage, lower ball races on the longitudinal carriage, upper ball races on the underside of the transverse carriage; and bearing balls interposed between the lower and upper ball races, the upper and lower ball races differing from one another in width, and at least the wider ball races being plane.
Claim 2
Dependent Claim
130 words
A gas cutting device for severing horizontally delivered material, comprising: a longitudinal carriage capable of travelling at the speed of delivery of the material to be severed on a track extending in the direction of delivery, a transverse carriage supported upon the longitudinal carriage, clamping levers for gripping the material to be severed and burners for cutting it, carried by the transversely movable carriage, crossbars forming part of the longitudinal carriage and extending over the track width of the longitudinal carriage, lower ball races on the longitudinal carriage, upper ball races on the underside of the transverse carriage; and bearing balls interposed between the lower and upper ball races, the upper and lower ball races differing from one another in width, and at least the wider ball races being plane.
Claim 3
Dependent Claim
44 words
A gas cutting device as claimed in claim 1, further comprising: ball cages, one for each of the said bearing balls, The ball cages being displaceable between the upper and lower ball races in the direction of movement of the material to be severed.
Claim 4
Dependent Claim
82 words
A gas cutting device as claimed in claim 2, wherein all the ball races are plane, and the upper ball races are wider than the lower ones, each ball cage consisting of a guide bar formed with a hole the diameter of which is equal to the diameter of the ball, and the device further comprising blocks arranged at both ends of the lower bearing races, the guide bars being displaceable upon the said blocks, and sidewalls laterally guiding the guide bars.
Claim 5
Dependent Claim
37 words
A gas cutting device as claimed in claim 3, further comprising a cylindrical casing mounted on each guide bar just above the hole containing the bearing ball, and substantially covering the upper half of the bearing ball.
Claim 6
Dependent Claim
36 words
A gas cutting device as claimed in claim 1, the transverse carriage being so mounted on the longitudinal carriage as to be capable of turning through a small angle relatively thereto about its central vertical axis.
Claim 7
Dependent Claim
37 words
A gas cutting device as claimed in claim 5, further comprising guiding rollers rotatable about vertical axes in opposite longitudinal sides of the transverse carriage, and bearing surfaces on the longitudinal carriage engaging the said guiding rollers.
Claim 8
Dependent Claim
25 words
A gas cutting device as claimed in claim 6, the engagement between the said guiding rollers and bearing surfaces being yieldable in the longitudinal direction.
Claim 9
Dependent Claim
20 words
A gas cutting device as claimed in claim 1, further comprising coupling means connecting the clamping levers with one another.
Claim 10
Dependent Claim
27 words
A gas cutting device as claimed in claim 8, further comprising pressure means freely engaging opposite sides of the transverse carriage and urging it into its midposition.
