US Patent:

40118339, Mar 15, 1977

Filed:

Aug 18, 1975

Appl. No.:

5/605475

Inventors:

Charles T. Hawkins - Verona PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

B05B 300

US Classification:

118323

Abstract:

A reciprocating spray device is provided with means for reducing vibration associated with reversal of motion at the end of each path of reciprocation. The vibration reducing means includes accelerative force transfer means which are contacted by the reciprocating spray apparatus at the points of reversal of its motion for transfer of substantially all of the reciprocating spray device accelerative forces to a spray bridge which is rigidly mounted to a carriage having shock absorbing means connected thereto and movably mounted on support means so that transferred accelerative forces from the reciprocating spray apparatus cause the carriage to move substantially parallel to and in an opposite direction from the motion of the reciprocating spray apparatus, and providing for the shock absorber to contact a fixed stop mounted in fixed relation to the supporting beam.

Abstract:

In the operation of a regenerative glass melting furnace to which glass batch materials are either continuously or intermittently fed as a layer onto the surface of molten glass in the furnace, a plow blade is periodically forced transversely across the width of the furnace at a location such that transverse grooves or depressions are plowed in the floating layer of glass batch materials. This provides for a floating layer of glass batch which is sufficiently contoured to efficiently receive heat from overhead heaters, such as flames from burners, in order to efficiently melt the batch making molten glass for forming.
