D II. F. CASE. WATER BOX FOR PAPER FINISHING ROLLS.
No. 430,112. Patented June 17, 1890.
A c A UNITED STATES ATENT QFFICE.
HENRY F. CASE, OF SOUTH MANCHESTER, CONNECTICUT.
SPECIFICATION forming part of Letters Patent No. 430,112, dated June 17, 1890.
Application filed August 27, 1889. Serial No. 322,152. (No model.)
To all whom it may concern:
Be it known that- I, HENRY F. CASE, of South Manchester, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in WVater- Boxes for Paper-Finishing Rolls, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.
The object of my invention is to provide a devicefor use in giving paper a waterfinisl1,
as it is called; and the device is preferably used in connection with and forms an attachment of a stack of calender-rolls.
To this end my invention consists in the combination of the finishing-roll and an inclined water-box with its delivery edges held in yielding contact with the roll, and provided with the adjustable outlet, as more particularly hereinafter described, and pointed out in the claims.
Referring to the drawings, Figure 1 is a detail face view, in elevation, of a stack of calender-rolls, illustrating the manner of embodying my improvement. Fig. 2 is a detail end view of part of the frame, the finishing-roll, and the water-box on an enlarged scale. Fig. 3 is a detail top or plan View, on an enlarged scale, of the water-box and the finishing-roll. Fig. 4 is a detail view,'in transverse section, of the water-box and the finishing-roll.
In the accompanying drawings, the letter (t denotes the frame of a stack of calender-rolls; b, the rolls, and 0 one form of water-box. The stack and its rolls are of ordinary construction, and the water-box c is of any suitable material, (metal preferred,) and it is pivotally supported in bearings secured to or formed in the uprights of the frame, the bearings being formed near the back of the box, so that the greater part of the Weight is in advance of the bearings on which it is free to turn. The underneath part of the front edge of the box rests directly upon the surface of a roll at a point above the horizontal plane of the center of the roll. As a result of such a method of suspension with respect to the roll, the box has a yielding contact and follows closely any play of the roll in either a horizontal or vertical direction.
The water-box is preferably formed with a rear wall 0 and end walls 0 the front side of the box or working edge in the form herein illustrated having preferably no wall. In its normal position this water-box is located with its bottom out of level to such an extent as to retain a certain quantity of water in the box, the water being deepest, of course, near the back end of the box and becoming rapidly shallower as the front edge is approached. It is desirable that means should be provided so that the-exact quantity of water flowing in a given time upon the roll, and by this means supplied to the paper, may be controlled, and to this end'I have provided the adjustable outlet d. In the bottom of the box a tubular outlet e is secured, that is connected with a pipe e, leading to any suitable outlet where the surplus water may be either allowed to accumulate or to run to waste. In this outlet is formed a threaded socket 6, into which the threaded stem of the valve d is fitted in such manner that the upper end of this valve may be raised or lowered with respect to the bottom of the box. My main object to be ac complished by the use of this adjustable outlet is to be able to control with all practical precision the depth at which the water will flow from the front edge of the box onto the roll, and in this way the quantity of water that will flow, and this adjustment is made within the box and at a point where the flow can be best controlled and the result of the adjust: ment immediately observed.
The water is supplied to the box through a supply pipe f, leading from any suitable source of supply. A portion of the water flows onto the roll and is used for finishing purposes, while the surplus overflows from the waste-pipe e.
In case the paper is of a thickness that requires the water to be applied to both sides in order to properly finish it, then two such water-boxes may be provided on opposite sides of the stack, but for ordinary purposes a single box on one side has been found sufficient.
Although my improvement has been described as particularly intended for use in water-finishing, it may obviously be equally well used for the purpose of sizing or supplying to the paper any other fluid for finishing purposes-as, for example, a coloring or a sizing fluid may be used in one of these boxesand my improvement is obviously not limited to the use of any particular fluid for finishing purposes. Nor is my invention limited to any specific form or arrangement of finishing-roll in any particular machine, as it is equally capable of embodiment in machines other than calenders. As the paper is liable to vary in Width, this is provided for by using an extensible dam adjacent to one or both ends of the front edge, the dam projecting along the edge from the side Wall and leaving an opening between the adjacent edges of the dam substantially equal to the with of the paper passing over the rolls. I have found it convenient to use a dam of plastic material that can be readily made and applied. Such adjustable outlet, whereby the depth of the fluid on the front edge of the box may be regulated, all substantially as described.
2. In combination With a paper-finishing roll, the Water-box pivotally supported on the frame of the roll, the said box having the rearward inclined bottom and an open front edge, the latter resting upon the finishing-roll above the level of its center, all substantially as described.
3. In combination with the stack of calender-rolls Z), the Water-box c, pivoted at its rear end to a bracket on the frame of the stack and having the inclined bottom and the open front edge resting with a yielding pressure on the surface of the finishing-roll, the outlet e,
with the threaded socket, and the tubular valve cl, fitted in said socket, all substantially as described. 7
