PAPER-MAKING MACHINERY.
SPECIFICATION forming part of Letters Patent No. 231,169, dated August 17, 1880.
Application filed July 13, 1880. (No model.) Patented in England January 5, 1876.
To all whom t may concern:
Beit known that I, GEORGE HoLLowAY, of Chartham, near Canterbury, in the county of Kent, in England, have invented certain new and useful Improvementsin Paper-Making-Machines, of which the following is a specitlcation.
My invention pertains to Fourdrinier papermachines, and applies particularly to the location of the slices which control the dow of the pulp to the wire, to the arrangement of the apron whereby no adjustment ot' it is required when changes in width of paper are to be made, and tothe arrangement ofthe deckles and their accessories.
By a combination of the improvements superior paper is produced, and no stoppage of the machine need occur as widths are changed.
In the accompanying drawings, Figure l is a side elevation of a Fourdrinier paper-torming machine with my improvements attached. Fig. 2 is a vertical longitudinal section of the receiving-trough anditsii'nmediate accessories; Fig. 3, a perspective view, part longitudinal vertical section, of the parts in the immediate neighborhood ofthe receiving-trough; Fig. 4., an elevation of the forward or second slice, E 5 and Fig. 5, an elevation of the packing-piece S, which prevents the side ow of pulp at the breast-roll, together with some of its adjuncts.
Ais the breast-roll, and G the receivingtrough. The front of the receiving-trough is provided with a flow-lip, W, whose edge forms a clamp, I. In this clamp is held the apron Q, which is of thin doubled sheet-rubber or other suitable material. This apron projects a quarter of an inch or so,and bears nicely on thebreast-roll A, or upon the wire, rather, upon the breast -roll. Fig. 5 shows these parts plainly. The lip and the apron extend from end to end of the receiving-trough, and are never disturbed when altering the width of paper. The apron will need renewal about as often as the wire does.
As shown in Fig. 2, two slices, D and E, are placed in the receiving-trough C, one of them, E, being very near the dow-lip apron. These slices control the flow of4 pulp to the wire, and theusual slices forward ofthe breastroll are dispensed with. This avoids the disturbance of the pulp after it has reached the wire, and allows a superior quality of paper to be made. The two slices D andE are adjustable vertically, as usual, by set-screws or any suitable means; and in practice I prefer to provide the forward slice, E, with means for adjusting different portions of its edge independently. This allows natural sag to be corrected, and gives complete control ofthe whole length of its edge.
In order to effect this adjustment of the edge of this slice, I provide the body of the slice with a blade, f, as shown in Figs. 2 and 4, fixed to the body of the slice at each end, as at Z in Fig. 4, and supported intermediately by screws d. These screws, being properly adjusted, cause the blade f to be exed vertically at any point and to any proper degree required. To render the blade j more flexible vertically, notches are cut in its upper edge to weakenit.
In all of the figures where shown, L is one ofthe deelde-frames for supporting the deeldepulley, Src. These frames are to be provided with any usual or suitable means for adjusting them sidewise in altering the width of4 paper.
F is a head decirle-pulley; B, a deelde-strap 5 l?, the table-rolls, N, the save-all, and O a scraper bearing upon the breast-roll A and draining into the save-all. The scraper O is removable, being attached to the edge of the save-all, and by its location is rendered selfwashing.
As shown in Fig. 3, the deckle-frame L has attached to its end an 'elbow-piece, Gr. This elbow is bolted to the frame at lVI, and after reaching around the pulley F, Ste., its long arm takes a bottom bearing tightly against the flow-lip W, being held down snugly by the spring H, or by any other suitable means.'
The face of the long' arm of the elbow bears nicely against the end V of the receivingtrough C, being pressed snugly by the spring K. .The joint-surfaces of the elbow-piece G may be padded to insure water-tight fits. The elbow G is seen to form a part of the deelde-frame L, and to be capable of moving with the deckle-frame as the latter 4is adjusted for different widths of paper. The elbowpieces form the water-tight front of the receiving-trough and allow the passage of pulp IOO to the wire only through the regular channel between the deckles and elbows.
After the top of the breast-roll is reached by the pulp the deckle-straps, of course, prevent improper side iiow; but between the top of theloreast-roll and the apron Q there are points where side flow may occur, and it becomes imperative that means be providedforclosingall side passages between the points named. This I accomplish by causing the short arm U of the elbow-piece to make a close joint on the wire from the front of the lip W to the point at the top of the breast-roll, where the decklestrap becomes effective.
The long arm G of the elbow-piece makes a close bottom joint with the iiow-lip, as previously mentioned and as shown in Fig. 5.
From theedge of the flow-lip to the edge of the apron Q side flowis prevented by the cushioned block J, whose bottom rests delicately upon the apron. This block may be affixed to the elbow in any suitable manner. From the edge of the apron to the point where the decklestrap becomes effective side iiow is prevented by the block S, which lits the wire neatly. The forward end of this block is thin and delicate, and is lightly pressed' against the decklestrap by the spring T.
The block S is best made of gutta-percha or some similar substance. As theblock Sis subject to wear at its lower edge, it should be provided with means for vertical adjustment.
In practice I render the block S self-adjustable vertically by affixing a weight, R, to it and itting the weight to slide in a mortise in the elbow-piece. By this plan a self-adjustin g water-tight joint is formed at all required points.
The blocks J and S'may, ofcourse, be in one piece, and may be said to form a packing for the short arm of the elbow, and the short arm of the elbow may, in fact, form the blocks or their substitute 5 but in practice I find the construction specified to be the most perfect.
The whole of the elbow-piece and its accessories are rendered more adaptable if pivoted at M, instead of rigidly bolted.
My improvements have been practically tested in the every-day work of the paper-mill, and it is found that owing to manner of slicing the owing pulp a superior quality of paper is produced, and that hourly alterations in the width of paper being made involve no stoppage or trouble.
I claim as my inventionl. The combination, with the receivingtrough, of two slices arranged within the trough and adapted to control the iiow of pulp to the 4. The combination, with a decirle-frame, a
breast-roll, and a receivin g-trou gh, of an elbowextension of the deelde-frame, adapted to'iit and form a water-tight joint upon the wire, upon the flow-lip of the receiving-trough, and against the end of the receiving-trough, and arranged to operate substantially as set forth.
5. Thecombination', with an elbow-extension of a decirle-frame adapted to prevent undesired side flow of pulp, of a packing-block adapted to f1t upon and adjust itself vertically upon the wire, substantially as set forth.
6. The combination, with a deckle-strap and a block adapted to fit the wire and prevent improper side flow of pulp, of a spring arranged to press upon and hold said block, or a portion of it, against the deelde-strap, substantially as set forth.
7. The combination, with a deckle-frame and a receiving-trough, of an elbow-extension of the decirle-frame, a spring to press said elbow-extension downward upon the receivingtrough, and a spring to press said elbow-eX-l tension against the end ofthe receiving-trough, substantially as set forth.
GEORGE HOLLOWAY.
