MASSACHUSETTS, ASSIGNOR OFVONE HALF TO L. DEWART APSLEY AND JUDSON H. COFFIN, BOTH OF SAME KNIFE FOR FINISHlNG WATER-PROOF FABRICS.
SPECIFICATION forming part of Letters Patent No. 375,305, dated December 20, 18H87.
Originalapplication filed October (i, 1886, Serial No. 215,442. Divided and this application filed October G, 1987. Serial No. 251,054.
l (No model.)
To all whom it may concern.-
Bc it known that I, THEODOR H. VIDETo, of Hudson, in the county of Middlesex and State of Massachusetts, have inventedV certain new and useful Improvements in a Knife for Finishing Tater-Proof Fabrics, of which'the following, taken in connection with the accomr set forth in my application No. 210,892, filed August 14, 1886.
. The main feature of novelty of my presen invention consists in a trough-shaped vessel, technically termed a knife,,7 having at its lower angle o-rbearing-face a series of perforations, each ,perforation entering a groove running across the knife.
An additional feature' of the invention consists in such trough-knife provided with one or more partitions.
By these improvements thesemi-lquid com pound placed in the trough may be deposited upon the contrastingly-coated surface ofthe fabric drawn beneath it and forml stripes of two or more colors.
In the drawings, Figure 1 is a perspective view of the trough-shaped knife, showing the perforations and grooves. Figs. 2 and 3 are sections of the same. Fig. 4 is a plan of my trough-shaped knife with a longitudinal partition.
Heretofore in themanufacture of gossamer I employ this apparatus and proceed in this manner to apply to the fabric all the coatings except the last; but the finishing-film I apply now be described. y
F indicates the thin textile fabric, coated onone side, as described, and to be striped with a rubber compound in solution. The fabric isin the form of an endless belt and is supported and moved by the rollers, as stated, both in applying the successive foundation-films and the finishing-stripes. After the foundation vulcanizing, the straight-edge knife is removed tion.
adapted to receive the semiliquid rubbercompound andA deliver the same in stripes upon the fabric through the perforations E, formed in the bearing face or edge of the trough. These ,running transversely across the loweredge of the trough.v vThe number and width and distance apart of the grooves determine the numbel-.and width and distance apartof thestripes. The edge walls of the grooves are well defined, so as to deliver vthe compound smoothly in stripes having a finished appearance.
f XVithout the grooves the rubbercompound in solution will not form the stripes properly, as the cloth with its foundation-coatings vis sagged by the pressure of the knife upon it and hugs up so close under the edge of the troughknife as to prevent the proper escape of the compound through the perforations; but with the shallow grooves H this difficulty is obviated.- 4The several perforations and grooves may of course be of different widths to form wide and narrow stripes. p
G is a partition, represented as running lonand atlixed or fitting snugly toits inner bottom surface, to permit the plaeingof two different striping compounds therein, one on each side of the partition". The .per-forations E are rubber coatings are spread evenly, and before D indicates my trough-shapedknife mounted I and held firmly in suitable supports and" perforations extend into shallow grooves H,v
shown in Fig. 4 as placed on each side of the in stripes upon the surface so prepared,as will v and my trough-shaped knife is substituted to form the stripes of rubber compound in soln- 65' gitudinally along the center of the trough D v partition alternately, with an unperforated space between them. NVith this plan the fabric produced willhave in its stripes three different colors or shades, one being that of the last foundation-coating; butpartitions may be otherwise arranged to enable the operator to apply more than two different-colored stripes as the finishing-film of rubber compound.
The trough-knife will be held firmly in the frame by suitable means, with its lower angle bearing on the fabric during one complete movement of the endless belt longitudinally through the machine, after which the fabric is treated in the usual way for such curing as may be required.
I claim as my invention- 1. In a knife coatingmachine, the troughknife D7 with perforations in its lower edge,
and shallow grooves extending from said perforations at right angles to the length of the 2o trough-knife, substantially as and for the purpose specified.
2. In a knife coating-machine, the troughknife D, with perforations and grooves, as described, and one or more partitions separating 25 itinto separate chambers, substantiallyas and for the purpose specified.
Intestimony whereofI have signed my name to thisspecifcation, in the presence of two subseribing witnesses, on this 4th day of October, 3o A. D. 1887.
