PACKING.
SPECIFICATION forming part of Letters Patent No. 513,273, dated January 23, 1894.
Application iiled April 4,'1893. Serial No.469,031. (No model.)
To' @ZZ whom t may concern,.-
Be it known that I, JOHN MURPHY, of Brooklyn,county of Kings, and State of New York, have invented a new and useful Improvement in Packing, of which the following is a specification.
Figure 1 shows a perspective view of the packing. Fig. 2 is a cross section of a part of the'same showing the 4internal construction when completed. Fig. 3 is a cross section showing the construction when partially completed. Fig. 4 is a perspective View of the material partially complete from which the packing is cut.
In constructing my packing, I first take sufficient fibrous material of the kind which is ordinarily used in manufacturing packing, as for instance duck, and having properly coatedfit on each side with rubber, I place a number of Alayers of it together in the ordinary manner and powerfully compress between rolls so that the various layers are made to adhere by the coating of rubber which they have received. In the drawings, these layers are lettered a, b, @,d, c, and f. I then pass transversely through these layers, stays g preferably coated by or run through a solution of rubber or rubber cement. I next pass the article between rollers where it isfagain strongly compressed and where the projecting ends of the stays are pressed down and embedded into the rubber coating of the duck, as shown in Fig. 4. I then place upon the exterior of the article shown in Fig. 4, the usual envelope h h of rubber in the ordinarygmanner and then vulcanize the whole. Out of the material thus formed, I cut an annular ring, as shown in Fig. 4, and slit the same diagonally as at t', whereupon the packing is complete and may be submitted to any of the known lubricating` processes before use.
The stays g may be4 applied in various ways. Thus, they may be applied by sewing lines of stitching Vacross the material after which the thread or cord or other material used in sewing may be cut at intervals between each stitch or left without cutting. In Fig. 3 is shown a series of ordinary running stitches j, j', t7'2 which have not been cut, and at another part a series of similar stitches 7c lo' which have been cut. I prefer the cut form because I believe that the raw ends of the cord form a more secure union with the vulcanized rubber on opposite sides of the duck. Instead of the running stitches, machine stitches -may be employed and for this purpose Il prefer to use the machine de scribed in Patent No. 383,248, dated December 29, 1885; or, instead of using any connected line of stitches atall, the stays might be separately inserted, when, without the necessity of cutting, they would be represented by the stays la k in Fig. 3. As the material for the stays I prefer cotton or linen cord.
The improvement introduced into packing by my invention consists in its ability to withstand wear without separating between the several layers. The stays that I have described, form a secure reinforcement against such separation.
I am aware of Letters Patent No. 314,848, dated March 31, 1885, and make no claim to the packing there shown in which to the completed packing are added pins, barbs or staples`o`f soft metal. In contradistinction to this, in my packing, it will befobserved that the stays are applied to a sheet of the raw material before it is cut into the form of a packing and before the application of the usual rubber envelope heh and beforevulcanization, so that the stays which connect Ythe layers of textile material are secreted beneath the' rubber envelope and are fixed in position by the vulcanization.
I claim-- Y 1. As an article of manufacture, an annular packing composed of Iinterior layers of fibrous material laid at right angles to the axis of the annulus and an exterior envelope of rubber, in combination with rubber intermediate the layers of fibrous material and stays beneath the rubber envelope whereby the union between the layers of fibrous material is reinforced; the bond between all parts being made by vulcanization, substantially as described.
2. The process of making annular packing which consists in uniting sheets of iibrous material by rubber reinforced by transverse stays, then enveloping the same on each side by a -sheet of rubber, then vulcanizing the material thus formed, then stamping an annular ring from the same, substantially as described.
p JOHN MURPHY.
