Description
rHoMAs HUNTER, or' PHILADELPHIA, PENNSYLVANIA. y
Letters Patent No. 111,749, dated February 14, 1871.
lMPROVEMENT IN LITHOGRAPHIC PRESSES.
The Schedule referred to in these Letters 'Patent andvmaking part of the same.
Be it known that I, TnoMAs HUNTER, ofthe city and county of Philadelphia, in the State of Pennsylvania, have -invented a new and useful Improvement in Lithographie Presses; and I do hereby deelarethe following to be :t full, clear, and exact description thereof, which will enable any person s liilleclin the art to which it appertains to malte and use my invention, reference being had to the accompanying drawing which forms a part of this specification, and which is a side view of so much of a lithographie press as is neeessary to show my invention.
A in the drawing represents the stone;
B, the distributing-table; and
G C, the damping-rollers by which the stone is moistened with water at each stroke, so as to prevent transmission of the ink to sneh parts' of the stone as retain the water.
Heretofore, so far as I am awa-re, it has been necessary for the pressman to dampen the rollers by wetting the distributing-table at intervals of from ten to fifteen minntes during the operation ofthe press.
The object of my improvement is Vtol replaec this labor ot the pressman by an automatic device; and
My improvement consists in the trough or fountain D, which is set in the reciprocating frame or bedvplate that carries the stone and distributing-table, and contains a-sponge. This fountain isftillerl with water enough to saturate the sponge, and at each stroke of the press it passes under the damping-rollers and moistens them slightly.
The tabledistribntes the moisture evenly on the rollers, and as the stone passes under them it receives the moist-nre.
That I claim esk my invention, and ldesire to secure by `Letters Patent of the United States, is-
rlhe reciprocating damping-fountain D, operetin g as described.
THOS. HUNTER.
Witnesses:
WM. 1t. WRIGHT, GEORGE E. BUCKLEY.
