FINISHIN GrMACHI NE FOR PRESS-BOARDS.
SPECIFICATION forming part of Letters Patent No. 295,521, dated March 25, 1884.
Application filed November 15, 1883. (N model.)
To all whom it may concern:
Be it known that I, FREDERICK L. CASE, of Chaplin, in the county of Windham and State of Connecticut, have invented certain new and chine embodying my improvement.
aview of the bed-plate in vertical section through the inlet-pipe. Fig. 3 is a view of the same in horizontal section through the chambers.
My invention relates to the class of devices used for finishing the surface of press-boards, binders board, and the like; and it consists in the use of the improved bed-plate, made hollow, and heated by steam or the like, that circulates through suitable inlets and outlets of the bed.
1n finishing press-boards (thick sheets of paper of ordinary material) they are subjected to heavy pressure on a bed and rolling friction under a roller attached to the lower end of a vibrating arm. To obtain the required finish and hardness of surface, the action of the roller is continued, in many instances to the great injury of the board, the fiber being broken and rendered so brittlethat the board breaks and crumbles under ordinary handling. By-means of my improvement I obtain the best results in firmness of stock, hardness of surface, and dryness of the board, with no injury to the fiber or stock.
In the accompanying drawings, the letter a denotes the frame of a finishing-machine, of
, usual construction and material; b, a bed of cast-iron; c, a vibrating arm pivoted to the vertical partition h. The bottom of one of the chambers, as f, pitches from the inlet of the steam-pipe t to the opening, and the other slopes from there to the outlet j, so that any water of condensation may flow out by the re- I turn-pipe 7c. The steam-pipe leads from any suitable source of supply, and the steam heats the bed-plate to any desired degree. When it is heated, the boards are place-d on the bed in the usual manner and passed between it and.
the roller, which, soon becoming heated by radiation, quickly finishes the board.
The advantages gained by my improve ment are marked in saving in time and labor of manufacture and in the quality of the product. 7
I am aware that paper-pulp has been formed to'shape, and that paper has been polished by the application of pressure and heat, and these I do not broadly claim.
I claim as my invention 1. In a finishing-machine for press-boards, in combination, the frame, the vibrating arm bearing the roller, and the bed-plate heated by steam, hot air, or the like, all substantially as described.
2. In afinishing-machine, the bed-plate with chambers f and 9, connected by opening 9,
FREDERICK L. CASE.
