OF PRODUCING Patented Oct. 27, m s;
Application ma January 25, 190a. Serial No. 412,546.
To all whom it my camera:
Beit known that I, JAMES Os'rnANDnR, a citizen of the United States, residing at Indiana olis, in the county of Marion and St ate of In iana, have invented certain new and useful Improvements in Packing and Process of Producing the Same, of which the follow- 1s a s ecification.
t has eretofore been customary to pro duce a packing, for piston rods and other similarparts, by taking a plurality of sheets or strips of fabric, such as canvas, asbestos, etc., coating the same with rubber or other suitable composition, and sticking together the several sheets or stri s into a pile or sheet which is then vul'canize cured or otherwise treated to bring it to the proper condition. This sheet is then cutinto strips or strings having a cross section which is-substantially square and in use-the box or gland is filled withrin formed from such strips and then subjecte to a compressive force in that direction of the cross section atright angles to the planes of the fabric laminae. A number of different formations have been proposed for the purpose of increasing the amount of transverseexpansion which may be accomplished by .the compressive to, such for instance, as that shown in my Patent No. 808,775. In the actual manufacture of the packingsuch as that shown in my above mentioned patent, ifthe laminae of fabric are regularly corrugatedor ly displaced before they are brought together, some difficulty is experienced in the commercial productionof such packing and the object of my present invention is to provide an improved process of producing packing having the fundamental characteristic of the aforesaid packing.
The accompany g drawings illustrate my invention.
Figure 1 is a perspective view of a. strip of laminated packing in process of production of my improved packing produced in acrove cordance wlth my im method; i, a similar view of a pac mg having the characteristics of that shown in Fig. 2 but having in addition a topand bottom plate or lamina of which is more uniformly corrugated and applied to the main body of the packing strip a perspective view illustrating the manner of improved process showing suitable means for subjecting the packing to a said strip comprising a plurality 'laminze 1 0 and inter leted it will be 2 a similar view 1 dition and con'sequei-iily l t0 tor the forming compression; F 1g. 4 a
i in that condition.
transverse compression in the line of one dimension of its cross section during curing. In order to practice my improvement in the art of producing packing I first produce a strip of material, such as is shown in Fig). l, of fa ric oscd yieldable cement 11 capable ultimat y of withstanding the temperatures to which the packing is to be subjected in actual use, such rubber. This strip maybe conveniently cut from a partially cured sheet built up as described and I prefer, in order to finally produce a packing strip of the usual dimensions harrin a cross section substantially square, to ma 0 that cross sectional dimension of the strip which is parallel with the fabric laminae somewhat greater than the cross sectional di mension atright angles to the fabric laminae. This strip is formed at a time rior to the final curing or other setting treatment and is then subjected to a transverse compression substantially parallel with the fabric laminae, thus causing a thickenin or wrinkling of the fabric laminae along 'Iines substantially parallel with the len th of the strip, the amplitude of the wrink es in the fabric as a whole or in the threads of the fabric transversely of the initial planes of the fabric being com aratively sma 1. While this wrinkled condition is extant the strip is subjected to a curing operation of such character as to set it in its.wrinklcd'condition, such for instance as by \ulcanizi ng in the usual manner.
I preferto mai tain thetransrerse compression during the curing rocess and for this reason the strip may he clamped between a pair of clamps 1.5, ll5 and held therein during the ,yulcanizihg or other curing process. After the curing has been comreadily' a parent that a coinressive force substantial iy atright angles to the original'com ressing force will tend to return the fabric iaminai to their initial conthe packing strip is capable of very considerable transverse wearing expansion, thus materially increasing its life.
If desired, after the strip has been subjected to its wrinkling compression, I may apply the top and bottom surfaces, finis nng laminae comprising fabric-stripslti 16 which have been more uniformly wrinkled and held T he application of these finishing surfaces or strips may take place for instance as substantially paral either before the curing of the main body of a plurality of fabric-laiilina and inter 'osed 5b the strip or these strips may 'be' separately; ru" ber to a distortin" pressure applieii in a cured and applied, y cementing or otherdirection, substantial y parallel with the wise, to the set strip in which the wrinkled planes of the fabric to wrinlde the Same a condition has been produced. transversely and treating the packing in its I claim as my inveiitionzfinkletl condition to a 'ciiring process to set 1.
