Abstract

An apparatus for passing heated fluid onto a material sheet and moving said fluid along the sheet to carve a pathway on said sheet.

Claims

1. An apparatus for carving a material sheet, said material sheet having material that is deformable at relatively low temperatures, comprising:

an elongated distributing element;

at least one nozzle mounted on the distributing element;

a fluid reservoir;

means for passing a carving fluid from the fluid reservoir, through the distributing element, the nozzle and to a position spaced from said nozzle; and

means for moving the distributing element and associated nozzle along a predetermined pathway relative to the material sheet.

2. An apparatus, as set forth in claim 1, including a plurality of nozzles mounted on a common side of the distributing means;

moving means for moving said material relative to the distributing element;

an actuating element connected to the distributing element for moving said distributing element in response to a received signal between a first material carving position at which the outlet ends of the nozzles are spaced a first distance from the material and a second noncarving position at which the outlet ends of the nozzles are spaced a second greater distance from the material. a detecting element in contact with the material sheet and connected to the actuating element for delivering one signal to the actuating element in response to movement of the material sheet for positioning the distributing element at the first carving position and for delivering another signal to the actuating element in response to the termination of movement of the material sheet for positioning the distributing element at the second noncarving position and terminating carving of the material.

3. An apparatus, as set forth in claim 2, wherein the actuating element comprises:

a two-way valve;

a double-acting hydraulic cylinder connected to the valve and to the distributing element;

a controlling element attached to the valve and to the detecting element for switching the valve and moving the distributing element between a first and second position in response to a signal received from the detecting element.

4. An apparatus, as set forth in claim 2, wherein the means for moving the distributing element and associated nozzle along a predetermined pathway relative to the material sheet comprises:

a power source;

a bell crank connected to the power source;

a connecting rod attached to the bell crank;

a swivel connected to the connecting rod and to one end of the distributing element for reciprocating the distributing element in one plane across a portion of the width of the material sheet.

5. An apparatus, as set forth in claim 2, wherein the means for moving the distributing element and associated nozzle along a predetermined pathway relative to the material sheet comprises:

a motor connected to a middle portion of the distributing element for rotary movement of said element in a plane substantially equidistant from the material sheet;

a controlling element connected to said motor for delivering a signal to the motor for rotating the distributing element in a clockwise and a counterclockwise direction at preselected time intervals.

6. An apparatus, as set forth in claim 2, wherein first and second shielding elements are attached to the distributing element on adjacent sides of each nozzle and extending from the distributing element into contact with the material sheet in the first position of said distributing element.
