Description
JAMES MOINTOSH, OF NORRISTOWN, PENNSYLVANIA, ASSIGNOR T DIAMOND STATE FIBRE COMPANY, OF BRIDGEPORT, PENNSYLVANIA, A CORPORATION OF DELA- Patented June Elli, 1918.
WARE.
. INDUTEID PRODUCT.
1,2 2 92 Specification of Letters Patent. I
No Drawing.
i To all whom it may concern:
. Be it known that I, JAMES MoIN'rosH, a citizen of the United States, and a resident of Norristown, Montgomery county, Penn sylvania, have invented an lndurated Product, of which the following is a specification.
One object of my invention is to provide a product particularly adapted for use in the manufacture of so-called noiseless gears, valves and the like, which shall be not only hard, tough and mechanically strong but in addition shall be impervious to oil, Water and moisture and a good insulator.
It is further desired to provide a-product of the above noted class which shall have as its base a membraneous animal substance mechanically worked and polished.
In carrying out my invention I saturate leather with a liquid, such as acetone, which is a solvent of synthetic resins such as those condensation products of phenol and for maldehyde known as condensite and backelite, and in the case of ordinary tanned leather varying from a quarter to threeeights of an inch in thickness, an immersion of thirty-six hours in this liquid is suficient. The saturated leather is then placed in condensite, baekelite or other liquid synthetic resin for about twenty-four hours in which time the acetone is displaced by such liquid ;it being noted however that this time as well as that required for the saturation with acetone maybe considerably varied without departing from myinvention, since it is dependent upon such variable factors as the nature and thickness of the leather as well as on the temperature, etc. I V i v The displacement of the acetone by the Application filed January 26, 1917. Serial No, 144,761.
liquid resin may be materially hastened by agitation, by subjectin the liquid to vacuum which removes t e acetone and by slightly heating the liquid, say to about 30 C. After the removal of the acetone, the leather, parchment or other animal membrane is dried at a temperature of from 100-150 C., for a time suflicient to cause the condensite or other synthetic resin to assume its solid form.
' The-product. resulting from the above described process is hard, tough and closegrained, being readily operated on by tools and capable of taking a high polish. It is moreover water and oil proof and is particularly fitted for use in hot, moist situations where it successfully resists disintegration and maintains its good electrical insulating properties.
If desired, after the leather or other animal fiber has been impregnated with the condensite or other synthetic resin, it may be built up in a series of layers to form a structure of any desired dimensions and thereafter be subjected to pressure and heat whereby such layers are caused to adhere at the same time that the synthetic resin becomes solidified. The resultant product, as in the case of a single layer, is homogeneous and capable of being mechanically worked into such structures as gears and valves.
I claim p 1. As a new article of manufacture an animal membrane impregnated with solidified synthetic resin. 2. As a new article of manufacture, leather impregnated with solidified synthentic resin. r
3. As a new article of manufacture, leather impregnated with solidified condensite.
'In witness whereof I affix my signature.
, A JAMES ncrnrosn.
