PACKING MATERIAL Filed Jan. 5, 1929 Y Fig.1.
Patented Apr. 29, 1930- HUGO BEINZ, OF BERLIN-SPANDAU, GERMANY PACKING MATERIAL Application fled January 5, 1929, Serial No. 330,400, and in Germany October 8, 1928.
In order to roduce a packing material (especially for t e cylinder blocks of internal combustion engines operating with high compression) which will fulfill all requirements the present invention employs a fabric of asbestos and metal of perfectly compact texture, in conjunction with an impervious 'material which forms a covering or sheathing for said fabric and is combined with the fabric to form a homogeneous whole.
Preferably, the fabric, which has already been woven as closely as ossible on the loom, is first impregnated with a heatand moisture-resisting substance for instance a phenolic condensation product such as thiolite, which is a sulphur derivative of a condensation product of formaldehyde and phenol. The fabric thus treated is then united with the impervious material, for exam le, a mixture of long-sta 1e asbestos, rub r and a suitable filler. e filler may consist'of any one of a variety of suitable substances, amon which may be mentioned by way of examp e, heav spar, magnesia and silicon. Instead of rub er, thiolite ma be used in order to render the mixture 0 the fibrous asbestos with the filler impervious. The union between the treated fabric and the impervious material is effected by rolling the impervious layers on to both sides of the fabric under heavy pressure and with-the collaboration of heat. In this way a web is produced which is flexible and capable of withstanding the highest temperatures, pressures and other 7 powerful stresses, which web can be cut by stamping without any further treatment, and can thus be brought into the desired shape for any type of packing, and particularly into the shape of the usual cylinder-block packing for internal combustion engines. At the same time, the most diversified combinations of asbestos and metallic filaments can be employed in the manufacture of the fabric, such as warps of metal and asbestos wefts," also asbestos-metal doubles for the warp, and on occasion, for both warp and weft; and so on.
The invention is illustrated, diagrammatically and by way of example, on the ac- 50 companying drawing.
Fig. 1 represents the asbestos-metal fabric before treatment.
Figs. 2 and 3 are res ectivel a cross section of the fab scale than Fig. 1.
Fig. 4 represents a cross section of the finished fabric.
Fig. 5 shows a c linder block packing made from the treate or finished material.
The warp threads a 'of the fabric consist of metal (preferably hosphor bronze of high strength) whilst as stos threads I) with a metal core serve as the weft. 'These threads a b are so closely interwoven that, asshown in Figs. 2 and 3, the fabric is extremely compact and close from the outset.
The fabric is next impregnated with the previously mentioned heatand moistureresisting material (e. g., thiolite) which renders the fabric completely impervious, without loss'of flexibility and suppleness.
The fabric so pretreated is next (Fig. 4) provided on both sides with an impermeable ayer c of suitable character, as described above, in such a way that the impermeable material is completely forced into the texture of the fabric, so that the fabric a b is, as it were, encased in the impermeable material on all sides. The homogeneous union of the fabric with the impermeable material is best assured by the already mentioned rolling-on of the latter under heavy pressure and with the collaboration of heat.
The Web thus formed can then be stamped a plan and ric bot on a larger out in the form of cylinder-block packings A (Fig. 5) and these, after being coated with graphite, can be placed in packing position without any further treatment.
Experiments have shown that the packing according to the invention fulfils the most stringent requirements in respect of pressure, resistance to heat and indeed in all other respects, and that there is no fear of corrosion or penetration of the edges of the packlng, especially at the susceptible parts d, notwithstanding the absenceof any marginal protection means. Another advantage is that the new packing can be thinner in sub stance than the cylinder-block packings hitherto in use. For this reason smaller surfaces are exposed to attack, the compression space can be correspondingly reduced, and the degree of compression therein accordingly increased, whereby the output of the engine is imp'oved and the fuel more favourably utilize Despite its high content of asbestos, the paoking,,is a heat conductor, and is distinguished by a very low loss on incineration. m In accordance with its texture, its strength is very high in all directions, that is to say,
in the. longitudinal and all transverse directions, due to the high tensile strength of the metal employed and due to the closeness, density and compactness of the fabric. It
is also to be observed that thestren h of the fabric is further increased by the brous asbestos employed in the impervious material which constitutes an integral part of the finished product.
I claim 1. A packing material composed of closely woven asbestos-metal fabric and a sheatlr ing of impermeable material intimately unit- 5 ed therewith to form an inseparable whole, said impermeable material being constituted by a mixture of asbestos, a filler, and a binder therefor. 1
2. A packing material composed of closeao ly woven asbestos-metal fabric comprising metal warp threads and asbestos weft threads impregnated with heatand moisture-resisting substance, and a sheathing of impermeable material intimately united therewith to form an inseparable whole.
3. A packing material comprising a closely woven asbestos-metal fabric comprising metal warp threads and asbestos weft threads impregnated with a heat and moisture resisting product of phenolic condensation, and
a sheathing of impermeable material intimately united therewith to form an inseparable whole.
4. A packing material comprising a close- 1y woven asbestos-metal fabric impregnated with a phenolic condensation product and a sheathing of impermeable material intimately united therewith to form an inseparable whole, said impermeable material being constituted by a mixture of asbestos, a filler anda binder therefor.
In testimony whereof I afiix my signature.
