MANUFACTURE OF EM BOSSED- LACE-PAPER.
SPECIFICATION forming part of Letters Patent No. 247,368, dated September 20, 1881.
Application filed May 11, 1881. (ModeL) To all whom it may concern Be it known that I, CHARLES LANG, a citizen or" the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in the Manufacture of Embossed Lace- Paper, of which the following is a specification.
My invention consists in embossed lace-paper the perforations of which have smooth edges on both sides of the paper, also, in producing the perforations in lace-paper by an abrading or rubbing action instead of by means of punches; further, in the combination, with a properly-engraved roller, of a brush which acts on the paper passing over theengraved roller, so as to produce the desired perforations; also, in the combination, with the engraved roller and the brush, of mechanism for imparting to said brush a lateral as well as a rotating motion; further, in the combination, with the engraved roller and the brush, of an embossing-roller, whereby a continuous strip of paper can be perforated and embossed at 2 5 one operation.
This invention is illustrated in the accompanying drawings, in which Figure 1 represents a sectional side view of my machine, the line :10 :r, Fig. 2, indicating the plane of section.
Fig. 2 is a front view of the same. Fig.3 is a transverse vertical section in the plane 3/ Fig. 2.
Similar letters indicate corresponding parts.
In the drawings, the letter A designates a frame, which forms the bearings for a shaft, B, on which is mounted a brush, 0; also for a shaft, D, on which is mounted an engraved roller, E, and fora shaft, F, on which is mounted an embossing-roller, G. The journal-boxes a,
a, which form the bearings for theshaft B of the brush, are adjustable by means of set-screws b b, so that the brush can be brought into the proper positidn in relation to the engraved roller, and the journal-boxes c c, which form the bearings for the shaft D of the engraved roller, are adjustable by set screws d (I, so that said engraved roller can be brought into the proper position in regard to the embossingroller. The shafts of the engraved roller and of the embossing-roller are geared together, so that these two rollers revolve with precisely the same superficial velocity. On the shaftB of the brush is mounted a small pulley, e, by means of which a rapid revolving motion is imparted to the said brush, and the shaft B slides in its bearings and receives a slow reciprocating motion in the direction of its length by means of a cam, j, which is mounted on the shaft D of the engraved roller, and acts on the end of the shaft B, which is pressed up against it by spring 9.
The paper which is to be manufactured into lace-paper is cut into strips of the desired width, and of any desired length, and these strips of paper are passed one after the other through my machine, (as indicated by a dotand stroke line in Fig. 3,) being drawn in by the action of the two rollers E and G. As the paper passes over the engraved roller E it is exposed to the action of the brush (J, and all those portions of the paper which bear upon the elevated parts of the engraved roller are rubbed or abraded, so that perforations are produced in the paper, which correspond to the design of the engraved roller. After the paper 7 5 has been perforated by the rubbing action of the brush it passes down between the engraved roller E and the embossing'roller G, and by the combined action of these two rollers it is embossed.
The brush 0, which I use by preference, is made of bunches of fine steel-wire, and I, im-- part to the brush a reciprocating motion in the direction of its axis, so that its points will wear off uniformly. The perforations produced in the paper by the rubbing action of the brush can readily be distinguished from perforations produced by punches orother equivalent means heretofore used in the manufacture of lace-paper, since the perforations produced by punches show burrs or beards on one side,while the perforations produced by the rubbing action are perfectly smooth on both sides.
Instead of the brush which I have shown in the drawings, 1 can use a drum covered with 5 sand, ground glass, or emery, or any equivalent material, or as above, and the brush may be made of iron wire, brass wire, or of any metal wire suitable for the purpose.
that I claim as new, and desire to secure 00 roller, the brush, and mechanism for imparting a lateral as well as a revolving motion to this brush.
5. The combination, substantially as hereinbefore described, of the engraved roller, the brush, the embossing-roller, and mechanism for imparting a revolving motion to each of said devices.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
