Abstract
Abstract In an apparatus with rotary jets of the kind wherein the jet unit is rotatably carried by a support which rotates about an axis perpendicular to the axis of the said unit (as for instance, the axis of the jet unit being horizontal and the axis of the support vertical), the support drives the jet unit through a speed reducing gearing with perpendicular axes (as for instance a worm gearing) which receives its motion from a planet pinion carried by the support and in mesh with a fixed crown gear, the number of teeth on the pinion and on the crown gear being incommensurable so that the jet unit is at different angular positions after each full revolution of the support.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
202 words
A vat descaling apparatus of the type comprising: a stationary hollow column adapted to be inserted into a vat to be descaled; a stationary annular gear provided at the lower end of said column; a driven support mounted on the lower end of said column and adapted to rotate coaxially with respect to said annular gear; means for driving said driven support; a jet carrying shaft in said driven support adapted to rotate about an axis perpendicular to the axis of said annular gear; and a gear mechanism disposed between said annular gear and said jet-carrying shaft, whereby rotation of the driven support with respect to the stationary annular gear will cause rotation of said jet-carrying shaft; said gear mechanism including a planetary pinion supported by the driven support and meshing with the stationery annular gear, the number of teeth on the said planetary pinion and said annular gear being such that an angular shifting is induced on said pinion after each complete revolution of the driven support; and further including a worm angularly locked with said planetary pinion and meshing with a worm wheel keyed onto the jet-carrying shaft, said worm and said worm wheel further dividing the said angular shifting.
Claim 2
Dependent Claim
202 words
A vat descaling apparatus of the type comprising: a stationary hollow column adapted to be inserted into a vat to be descaled; a stationary annular gear provided at the lower end of said column; a driven support mounted on the lower end of said column and adapted to rotate coaxially with respect to said annular gear; means for driving said driven support; a jet carrying shaft in said driven support adapted to rotate about an axis perpendicular to the axis of said annular gear; and a gear mechanism disposed between said annular gear and said jet-carrying shaft, whereby rotation of the driven support with respect to the stationary annular gear will cause rotation of said jet-carrying shaft; said gear mechanism including a planetary pinion supported by the driven support and meshing with the stationery annular gear, the number of teeth on the said planetary pinion and said annular gear being such that an angular shifting is induced on said pinion after each complete revolution of the driven support; and further including a worm angularly locked with said planetary pinion and meshing with a worm wheel keyed onto the jet-carrying shaft, said worm and said worm wheel further dividing the said angular shifting.
Claim 3
Dependent Claim
59 words
In apparatus as set forth in claim 1, said driving means comprising a shaft housed within the hollow column; a drive motor for said shaft at the upper end of the column; reduction gearing disposed between the motor and shaft; a cylindrical hub carried by the lower end of said shaft, said hub having journaled therein the said worm.
Claim 4
Dependent Claim
40 words
In apparatus as set forth in claim 2, an annular flange fixed to the lower end of the hollow column; and a ring gear fixedly mounted on the lower end of said annular flange and forming said stationary annular gear.
Claim 5
Dependent Claim
140 words
In apparatus as set forth in claim 2, said shaft of the driving means being hollow below the motor and being connected to a supply of fluid under pressure, the lower end of said shaft communicating with a fluid duct extending downwardly into said hub; said hub having a cylindrical part in which the jet-carrying shaft is journaled in spaced relation to the walls thereof; an annular sleeve in said cylindrical part disposed around said jet-carrying shaft and communicating with the said duct of the hub for confining fluid from the said duct around said jet-carrying shaft; said jet-carrying shaft being hollow from said annular sleeve to the outer end of said shaft, and having ports therearound in way of the sleeve for conducting said fluid from said ports to the outer end of the jet-carrying shaft for spraying purposes.
