IMPROVEMENT IN MACHINES FOR WATER-MARKING PAPER.
Specification forming part of Letters Patent No. 166,122, dated July 27,` 1875 5 .application filed February 21, 1874.
To all whom it may concern:
Beit known that I, MATHEW MATHEWS,y
-invented certain Improvements in Apparatus for Water-Marking Paper,` of Which the following is a specification:
The object of my invention is to so construct the Water-marlrin g appliances of paper-makin g machines as to insure the rotation of the marking-roll at the same surface speed as the Wire-cloth While the water-mark is being imparted to the paper. This object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in Which- 4Figure l is a plan view of part of a papermaking machine With my improvements attached. Figs. 2 and 3 are enlarged sectional views, showing modes of attaching the designplate to the skeleton-roll; and Fig. 4, an enlarged View of part of my invention.
The usual method of making the Watermarking device is to form it of Wire and sew it on the dandy-roller; but this necessitates a separate roller for each design, and it will be evident that in large manufactories the cost and bulkiness of the many rolls required is a serious objection. y
On this account I prefer to employ, in conjunction With a plain dandy-roll, B, a skeleton-roll, A, to which marking-plates are attached, as shown in Figs. 2 and 3. These rolls turn in suitable bearings in the frame Y ofthe machine, and the roll A I prefer to operate from the decirle-shaft D, through the medium of a belt, w, passing over* a loose pulley` a', on the end of the said roll A. A pin, y, on the pulley x bears against a stud, z, keyed on the end ofthe skeleton-roll, which is thus rotated (hiring the operation of the machine. The plates a, bearing the Watermarking design are mad-e in the arc of a circle of the proper diameter, and attached to the anges b of the skeleton-roll A, so as to be readily detachable therefrom, as shown in Fig. 2. In the modication, Fig. 3, the plates are made straight and attached to flanges on the arms b of the roll, the surface of the design or lettering being rounded oli' to the marked by the plate a ou the skeleton-roll,
and thence it passes to the couching-rolls. The diameter ofthe loose pulley a is made proportionate to the size of the proposed sheet of paper, so that the Water-marker may be brought round at the proper moment through the medium ofthe pin y and stud z. In case the pulley x should notoperate the roll A at the same speed as the surface speed of the Wire-cloth, I arrange the rounded portion f of the segment E on a line with the y marking-plate a., so that from the moment the said portion f comes in contact with the Wirecloth W,'Fig. 4, the roll must move at the lsame surface speed as the said Wire-cloth.
When the said rounded portion of the segment passes out of contact with the Wire-cloth,
'the roll A ceases to move until the loose pulley .r brings the pin y again in contact with the pin z. Thus the marking-plate a is caused to rotate at the same surface speed as lthe Wirecloth during the formation of the Water-mark, While, at the same time, the marking-plate is brought round at the proper moment to corre-` spond with the size of the sheet to be made.
I claim as my invention- The segments Eon the skeleton-roll, and having rounded portions f on line With the marking-plates a, in combination avith the Wire-cloth W, whereby the said plates a are caused to move at exactly the same surface speed as the said Wire-cloth during the formation ofthe Water-mark.
MATHEW MATHEWS.
In presence of- THOMAS MURPHY, J. NoDHEN.
