UNITED STATES I Patented July 12, 1904.
PATENT OFFICE.
ANTON AAGAARD, OF EVERETT, IVASHINGTON.
SPECIFICATION forming part of Letters Patent No. 764,97 1, dated July 12, 1904, Application filed January 27, 1904. Serial No. 190,876. (No specimens.)
To all whom, it natty concern.
Be it known thatI, ANTONAAGAARD, a citizen of the United States, residing at Everett, in the county of Snohomish and State of ashington, have invented certain new and useful Improvements in Waterproof Leather Dressings and Preservatives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in waterproof leather dressing and preservative, admirably adapted to preserve and render soft, pliable, and waterproof the leather to which it is applied.
In manufacturing my new composition I use tar made from the roots of pine trees, preferably the so-called Stockholm or Nor- Wegian tar, dogfish-oil, (Squalus sucklcyi) and turpentine in the following proportions: five parts pine-root tar, fourteen parts dogfish-oil, one parttu rpentine. These are mixed well together and boiled, as follows: If the dogfish-oil (Sq wales suclzlcyz') has been procured by trying out the livers by heat, then the compound need be boiled but from fifteen to twenty-five minutes. If the dogfish-oil is raw -thatis, oil drawn from the livers without heatthen the whole mixture must be boiled from thirty to forty-five minutes. The duration of the boiling period is material, as if the mixture is boiled for a less time than is required there will not be a thorough mixture of the ingredients, whereas if boiled for too long a period of time the mixture will become hard and brittle and of little value as a leather-dressing, and the exact time of boiling must be determined by the results thereby obtained, as determined by the tests.
The pine-root tar is commonly called Stockholm or Norwegian tar and differs from the tar procured from the Carolinas in that the Stockholm tar does not contain any granular substance which would tend to injure the leather.
It is desirable to use the turpentine, as thereby better results are obtained; but the proportion of turpentine may be varied greatly and in some instances entirely omitted without material loss of efficiency.
The oil employed in the present process for making waterproof leather-dressing is obtained from the liver of a fish commonly known as dogfish, (Squalus suckleg z'.) I preferably procure the oil from the liver by steam heat .while the liver is fresh, the oil thus containing no granulous substances and no harsh fish odor, and by boiling this oil together with the tar above specified the compound becomes very thin, so that when it is applied to leather it is absorbed thereby into the pores, and there remains no greasy matter on the surface of the leather, thereby producing results of material advantage to the leather, such as the softening and preservation thereof.
The mixture when properly boiled and cooled serves as a waterproof preservative dressing for leather which is unexcelled in efficiency. Owing to the nature of the ingredients,'wl1en the mixture is applied to the leather the oil will soften the same and the tar, filling the pores of the leather, will render it impervious to moisture.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A leather-dressing comprising amixture of dogfish-oil and pine tar.
2. A leather-dressing comprising amixture of dogfish-oil and pine-root tar.
3. A leather-dressing comprising a mixture of dogfish-oil, pine-root tar and turpentine.
4. A leather-dressing comprising a mixture of dogfish-oil, from live to fourteen parts, pine-root tar, from one to five parts, and turpentine.
5. A leather-dressing comprising a mixture of fourteen parts dogfish-oil, and live parts pine-root tar substantially free from granular material.
6. A leather-dressing, comprising a mixture of dogfisli-oil and tar.
7. A leather-dressing, comprising a mixture of dogfish-oil, turpentine, and tar.
