RESILIENT GASKET FORMING MATERIAL AND METHOD OF PRODUCING SAME Filed Sept. 17, 1955 2 Shee tsSheet 2 IN V EN TOR. may Mp6 5?- United States atent This invention relates to fabricated resilient material from WhlOll gaskets and like articles can be formed, and to method of producing said material.
The invention has for an object to provide a resilient metallic material from which gaskets and like articles can be formed, which material, although it readily yields to compression, will, when compressing pressure is relaxed, possess marked ability to recover its normal cross-sectional shape; in other words, a resilient compressible metallic material having a high coeflicient of recovery so that, in use, it will not crush or mat down into a permanently deformed or flattened condition but, on the contrary, will quickly respond to effects of expansion and contraction of parts between which it is engaged, and will therefore maintain complete and constant contact with said parts at all times.
The invention has for a further object to provide a resilient metallic gasket or like article forming material, characterized as above stated, which can be used to form an all metallic gasket or like article, or can be used as a core to yieldably support an enclosing fluid impervious jacket, a fire resistant jacket, or jacket providing other desired characteristics, whereby to provide gaskets or like articles having such desired characteristics.
The invention has for another object to provide method procedure by which to fabricate the resilient metallic material having the above stated characteristics.
The above and other objects will be understood from. a reading of the following detailed description of this invention in connection with the accompanying drawings, in which: i
Fig. 1 is a face view of a flattened strip of tubular knit hard metallic wire which provides the base stock from which the resilient gasket forming material of this invention is produced.
Fig. 2 is a face view of the flattened stock strip of Fig. 1 after the same has been treated to form therein corrugations extending diagonally across its width.
Fig. 3 is a side elevational view, in part longitudinal section, showing the corrugated stock strip helically wound and lapped upon itself to form a running length of tubular resilient gasket forming material providing 01156111- bodiment of this invention, wherein the corrugations of the helically wound stock strip are disposed oblique to the longitudinal axis of the material.
Fig. 4 is a side elevational view of the tubular resilient gasket forming material of Fig. 3 enclosed in an external covering sleeve of tubular knit wire.
Fig. 5 is a View similar to that of Fig. 4 but showing the tubular resilient gasket forming material further provided with an internal lining sleeve of tubular knit wire.
Fig. 6 is also a View similar to that of Fig. 4, but showing the resilient gasket forming material used to provide a corefor the support of an external jacket of selected desired characteristics.
Fig. 7 is a view similar to that of Fig. 3 but showing the corrugated stock strip so helically wound and lapped upon itself as to produce a running tubular length of resilient gasket forming material providing a modified embodiment of the invention, wherein the corrugations of the helically wound stock strip are disposed parallel to the longitudinal axis of the material; and Fig. 8 shows the material of Fig. 7 enclosed in an external covering sleeve of tubular knit wire.
In fabricating the resilient metallic gasket forming material of this invention, an indeterminate length of tubular knit metallic fabric is produced on a circular knitting machine. The tubular fabric is knitted from a hard metallic wire, such as nickel-steel wire of suitable gauge, in such manner as to form a knitted mesh of comparatively small loop size, and a tubular body of such diameter that when it is flattened an indeterminate running length of stock strip 16 of selected width will be provided (see Fig. 1).
After the tubular body of knit fabric is flattened to form the stock strip 10, said stock strip is run through suitable corrugating rolls whereby to provide the same with successive corrugations 11 extending \diagonally across its width (see Fig. 2). l
The body of the resilient gasket forming material is produced by helically winding the corrugated stock strip ill-11 about a mandrel of selected rdiameter (not shown), along which mandrel the helically wound formation is advanced, and from which it is continuously discharged. The corrugated stock strip ill-11 is led to the mandrel at a predetermined angle, so that, as revolved around said mandrel, each successive helical convolution formed around the mandrel will lap a preceding formed convolution, preferably in extent of half the length thereof more or less. By this procedure, a tubular body 12 of indeterminate length, comprising a succession of lapped helical convolutions 13 is formed. Preferably the corrugated stock strip ltl-11, as fe d onto the mandrel for winding about the same, is so disposed that the corrugations 11 of the formed convolutio-ns 13 will extend oblique to the longitudinal axis of the mandrel and therefore oblique to the longitudinal axis of the helically Wound body of the resultant gasket forming material (see Fig. 3).
Since the corrugated stock strip comprises two plies, the overlapping of successively wound helical convolutions thereof will build a wall comprising four corrugate plies of the knitted wire mesh, with the corrugations thereof substantially intermeshed or nested one in another in such interlocking relation as to form a comparatively dense and springy wall structure. Such Wall structure will yield to pressure substantially perpendicular to the longitudinal axis of the formed tubular body, but in so doing will set up such reactionary internal tensional stresses in the wall structure as to assure recovery of the laterally depressed tubular body to its normal crosssectional shape when pressure is relaxed. The diagonal disposition of the interlocked corrugations further promote resistance to lateral pressure so as to increase reactionary tension in the wall structure when the tubular body is subjected to lateral compression.
The resilient metallic gasket forming material, characterized as above set forth, can be wrought into an annular or other desired gasket formation suitable formany uses where an all metallic, elastically compressible gasket or like article is required. In many cases, however, it is desirable to enclose the resilient metallic gasket forming material in an external enveloping sleeve of tubular knit mesh, knit from a suitable wire or other strand, whereby to better hold the helical convolutions of the tubular body against relative displacement, and to facilitate handling of the gasket forming material in bulk. This is shown in Fig. 4 wherein the material is provided with a covering sleeve 14 of tubular knit wire, said sleeve being partially broken away in this view to disclose the underlying tubular body 12 of the gasket forming material. It is sometimes also desirable, as shown in Fig. 5, to provide the tubular body 12 of the gasket forming material with an internal supporting sleeve or lining 15 of tubular knit springy wire. Such provision enhances the tensional resiliency of the material. It will be understood that the internal supporting sleeve or lining 15 may be used without the external covering sleeve 14, and vice versa, accordingly as circumstances of use of a gasket or like article formed from the material may dictate. I
If it is desired that a gasket or like article formed from the resilient metallic material be impervious to fluid, or that it be fire proof or fire resistant, then said material may be encased in an external jacket 16 of a suitable fluid impervious material in the one case, or of fire proof or fire resistant material, e. g. an asbestos fabric, in the other case (see Fig. 6). It will be understood that the jacket 16 may be of selected material providing both the fluid impervious and the fire proof characteristics if this be desired.
Referring now to Fig. 7, a modified embodiment of the resilient metallic gasket forming material of this in vention is shown therein. This modified form of the material is also produced from the corrugated knitted wire stock strip 10-1l by helically winding the same around a mandrel, to which said stock strip is led at a predetermined angle, so that, as revolved around the mandrel, each successive helical convolution will lap a preceding convolution, whereby to produce a tubular body 12 of indeterminate length. In this case, the stock 's'trip, as fed ontothe mandrel for winding about the same, is so disposed that the corrugations 11 of the formed convolutions 13 will extend parallel to the longitudinal axis of the mandrel, and therefore parallel to the longitudinal axis of the helically wound tubular body formation. The corrugations of contiguous plies of the wound strip Will become substantially intermeshed or nested one in another, but owing to the disposition thereof parallel to the longitudinal axis of the tubular body, said body will be somewhat softer and less resistant to compression, although still possessing a high coefficient of recovery from compression. This modfied embodiment of the material may also be enclosed within an external tubular knit covering sleeve 14 (see Fig. 8). It will also be obvious that this modified form of the material may be provided with the internal supporting or lining of tubular knit wire 15 if desired. It will also be understood that this modified form of the material may be encased in the fluid impervious or fire proof or fire resistant jacket 16 if desired.
It is also pointed out that a composite structure which combines both above described embodiments of the helically convolute bodies may be produced by superposing wound convolutions of one upon the wound convolutions of the other, with a selected one of the forms being disposed as the inner winding while the other is superposed as the outer winding.
It will also be understood that a multiple of windings of either or both types of the helically convolute bodies may be wound one upon another to build up the material to desired body thickness. This may be done in such manner that the corrugations of contiguous windings either nest together or cross one another, according to the degree of density and resiliency desired to characterize the finished product.
The composite structures above mentioned may be provided with an external covering sleeve 14, an internal supporting or lining sleeve 15, or both, and, if desired, with the fluid impervious or fireproof or fire resistant jacket 16.
