CONSTRUCTIONAL UNIT AND METHOD OF MAKING SAME A. c. FISCHER Filed April 16, 1928 til Patented Jan. 21, 1930 I UNITED STATES PATENT OFFICE ALBERT G. FISCHER, OF CHICAGO, ILLINOIE, ASSIGNOR TO THE PHILIP CAREY MANU- FAGTURIHG COMPANY, A CORPORATION OF OHIO @ONSTBUOTIONAL UNIT AND METHOD OF HAKING SAME Application filed April 16,
This application relates to subject-matter shown and described in my Patent No. 1,591,670, issued July 6, 1926 and particularly pertains to constructional units of cellular, sponge-like structure and the method of makmg same.
The invention is typified by a rail filler which is adapted to be inserted in the cavities of car rails and separate them from the pavement structure.
A rail filler of sponge-like structure may be fabricated from a bituminous mixture in which an air-pocketing ingredient has been incorporated to distribute air cells through; out the bituminous mass.
A suitable air-pocketing ingredient is a degummed fibrous material. lFlbIOllS material, such as, hemp, fiax, straw, and the like, is treated with caustic soda to remove the gummy matter and increase its capillary attraction, after which it is immersed in a mass of heated bituminous material. The degummed fibers absorb and draw the heated bituminous material through the structure, thereby forming a bituminous wall about the numerous air pockets, and creating a spongy cellular body. In this condition the mixture is formed in constructional units of any desired form, and suddenly chilled as by immersing in cold water.
Various chemicals used in the treatment of rubber, sponge rubber and its pre aration tor vulcanization may be employe to further provide toughness and a rubbery character to the fibrated bituminous mass.
This cellular structure diders greatly trom that shown in previous inventions, in that the air pockets are closed and sealed.
Where solid bituminous matter has been used under pressure, tor instance the pressure upon'it of adjoining paving sections incident to its use as a paving joint, there is an elongation or lengthening of the mass and'an 0ozing out from the packed space, which conclusively shows that the body is not inherently compressible. Likewise with laminated joints where the felt has been saturated and squeezed between rollers, then laid together with a solid asphalt layer, there is no inherent compressibility.
1928. serial at. 270,519.
Where hemp, rope, and other packing materials are used they are immersed in a light waterproofing material or solidly saturated so no cellular structure exists, as herein described. Under pressure most oi? the joints ooze out of the crevice and lie over on the pavement, thus preventing the substance reentering the crevice.
By inherently compressible paving joint, ll mean one which can be compacted into a lesser space without elongation or displacement of its contained bituminous matter or equivalent waterproofing and air pocketing ingredient. Such a joint is caused to adhere to the faces of the opposing pavement slabs, and its expansion in response to contraction of the slabs is more real and rapid than is possible with a solid orboardlike structure.
This invention relates to constructional material comprising a preformed matted structure having capillary action, immersed in bituminous material, said bituminous material being carried thru the fibrous matted structure by the capillary action and permeated therewith.
Figure 1 represents a mass of the material, (2 illustrating the waterprooted fiber, and b the air spaces between the fiber.
Figure 2 represents the material formed into rail filler, (1 representing the filled degummed fiber, and b the air spaces between the fiber.
l claim:
1. Constructional material comprising a preformed, degummed, matted structure having capillary power, treated with a bituminous material and permeated therewith.
2. @onstructional material comprising a pretormed, degummed, matted fibrous structure permeated with bituminous material thru the capillary action of the degummed fibrous structure.
3. Rail filler comprising a preformed, 'degummed, matted structure having capillary power, treated with a bituminous material and permeated therewith.
t. Rail filler comprising a preformed, dcgummed, matted fibrous structure permeated with bituminous material thru the capillary action of the degummed fibrous structure.
