RAILROAD-TIE COM'POSITION AND PROCESS! NoJDrawing.
To all whom-it wu'qz concern:
Be it known that I, HENRY GEORGE JAE- ;nn, a citizen of the United States, residing at Rose Hill, in the county of Los Angeles and Statesofr'Galifornia, have invented new and useful Improvementsin a RailroadTie Compositionna'ndcProcess, of which the following is a specification.
My present invention relates to composi- Lions and processes for use in the production of railroad ties or the like, and particu larly in the production of railroad ties or similar structural units, such as fence posts, barges or the like, for use in tropical climates, one object of my invention being the production of an inexpensive material, relatively light and relatively permanent, which shall be resistant not only to the action of fire and water, but resistant also to the attacks of ants or other pests which render the use of lumber unsatisfactory in tropical climates.
Further objects of my invention are the production of a composition of the general character indicated which shall be of low conductivity to heat, sound and electricity, and which shall undergo little expansion or contraction or warping as a result of thermal or climatic changes.
A further object of my invention is the production of products of the general character indicated which can be worked with ordinary wood working tools, and which can be flexed, and which shall have superior tensile strength whether cast or molded, and which can be nailed, screwed or spiked in the manner of lumber, and which can be permanently colored to any desired shade by means of such coloring agents as are not adversely affected by contact with lime.
Further objects of my invention will appear from the following description and the claims appended thereto, the shock absorbing qualities being important in certain uses of my invention, as when the same is used in the construction of docks, or the like.
In a preferred embodiment of my process, I admix or saturate about seven parts of loose organic fibrous material, such as wood shavings, with. sufficient of a preservative liquid, such as crude carbonic acid, and
Application fi1ed:0ctober 4, 1922. Seria1No.-592,42 1-i preferably comprising a phenol, to com pletely permeate the same, and then permit thismaterial'to'drain untilrit shall be substa-ntially .dry; The employment of crude carbolic'acid isadvantageous not only on ac count; of its. preservative action but: on ac count of the aversion of ants thereto, this aversion being attributed by me to the presence of carbolic acid.
Separately from the above, I prefer to form a mixture of one part by volume of finely powdered calcined magnesite with one part by volume of silica so finely pulverized as to pass 200 meshes to the inch. Having added to seven parts of the fibrous material conditioned as above suflicient of a 12 Be. solution of magnesium chloride to saturate the same, I permit this material to drain and then add one part of finely powdered calcined magnesite thereto, after which I thoroughly mix together all of the materials above mentioned and saturate the same with a 22 B. solution of magnesium chloride in sufficient quantity to form a plastic mass. The whole may then be molded into the desired shapes in suitably prepared forms, in which it should be permitted to undergo a recrystallization while drying, sufficient heat to effect this drying being generated by the chemical interaction of the materials mentioned.
lVhile I have above described in detail one preferred embodiment of my invention, it will be understood that certain features thereof may be independently employed, and that various modifications may be made therein, without departure from the scope of the invention as indicated above and as set forth in the appended claims. In particular, it should be observed that the organic fibrous material employed in my process may be any one of a great variety of substances selected according to conven-.
ience in the locality where my process is used. Pampas grass, rice roots, sugar cane, and even the brush or scrub of the region through which a railroad is to pass, may advantageously be employed, according to local conditions.-
lVhatI claim is: 1. A composition Suitable for the P ant:
iacture of railroad ties comprising about seven parts of an organic fibrous material conditioned by saturation with a preservalive liquid comprising a phenol, then dried, saturated with a solution of magnesium chloride, and admixed with about one part of powdered calcined magnesite.
2 A composition suitable for the manu-- iatture of railroad ties comprising about so en parts of an organic fibrous material conditioned by satu *ation with a preservative liquid comprising a phenol, then dried, saturated with a solution of magnesium chloride, admixed with powdered calcined ma gnesite the fibrous material being used in the ratio of about seven parts by weight to one part of magnesite and the Whole being then admixed with a preparation comprising one part of silica and one part of magnesite (be whole being thereafter moistened with sufficient of a 22 B6. solution of magnesium chloride to give the same a plastic consistency.
2-3. In the process of preparing from plastic materials structural units such as rail road ties especially suitable for use in tropical climates the steps which comprise conditioning a loose fibrous organic material by saturating the same with a preservative comprising a phenol, drying the same, saturating the product with a solution of magnesium chloride, adding calcined magnesite thereto, separately preparing a mixture of finely powdered silica and linely powered calcined magnesite, associating all the materials above re'terred to, and moistening the whole with sufiicient of a solution of magnesium chlorideto give the same a plastic consistency.
In testimony whereof I have signed my name to this specification.
H. G. J AEGER.
