A. c. FISCHER IETHOD 0F PREPARING EXPANSION JOINT COMPOSITION Filed Hay 10, 1922 INVE OR Patented Aug. 7, 1928.
UNITED STATES PATENT OFFICE.
METHOD OF PREPARING EXPANSION-JOINT COMPOSITION.
Application filed May 10,
The invention relates to improvement in expansion joints and to the method of the construction of same, as more fully described hereinafter and particularly pointed out in the claims.
Heretofore it has been the practice in the manufacture of expansion joints to impregnate felt strips and build them into layers or reinforce asphalt mixtures with saturated felt sides, also the prior art teaches fibrous matter mixed withtar, pitch or bituminous substances.
In all the instances known to me the fibrous matter has been impregnated with the water-proofing mass to an extent which defeats the purposes of the present invention; that is to say the mixtures have been effected with materials heated to such a consistency that the contents are saturated thoroughly and the mass becomes a saturated mixture and consequently contains few if any air cells. On the other hand the rigidity of the fibre for structural purposes is destroyed, and it does not act as a separate structural skeleton for the surrounding mass. Consequently, in warm weather expansion joints made by the old method become limp and flabby, because of their lack of structural framework acting independently of the surroundin mass.
By my method 0 mixing cellular granules, unsaturated fibrous matter and other like substances such as excelsior cut in small lengths, stiff fibrous flax, etc. and incorporating same in the mixture while the .bituminous matrix is merely plastic as distinguished from liquid and therefore lacking in penetration power, I am able to effect a structural skeleton within the matrix which supports the matrix in warmer temperatures; and because of the inherent physical properties of the granules, fibrous matter, or the like.
I am also able to eflect cells or pockets in the structure which allow for compressibility, and because of the unsaturated materials or cellular granules the walls of the bituminous matrix which surrounds the particles cannot adhere together upon compression and will therefore respond to expansion upon release of the compression. Certain fi res, such as, mineral wool cause the walls of the matrix to harden immediately where in contact, which also make for a stronger structure, so that there is a structural strengthening both by chemical action and 1922. Serial No. 559,908.
by preserved rigidit in the fibrous matter which is unsaturate I have afforded through this method the possibility of effecting several types of structure, namely a bituminous and fibrous mixture effecting a chemical change strengthening the structure, a bituminous and fibrous mixture strengthening the structure due to unsaturated brous matter; a bituminous cellular structure containing within the cells granules, such as, cork, which in itself is cellular, screened mineral wool granules, which are also cellular, treated wool granules in a cellular state and any other like form of cellular or fibrous matted matter, such as, excelsior, digested straw, flax, etc. in an unsaturated state, or at least not solidly saturated by penetration of the bituminous matrix.
In the drawings, Figure 1 represents an expansion joint containing bituminous material (a) and mineral wool fibre (b) the chemical action of the fibre having strengthened the bituminous wall immediately about them.
Figure 2 illustrates an expansion joint consisting of bituminous material (a) having incorporated therein granules for the purpose of forming cells (a) or pockets (0) and the cells or pockets in turn filled wlth cellular matter (d unsaturated, but which may be waterproo ed with a non-sticky substance, so that the bituminous walls of the enclosing cells or pockets cannot adhere when compressed, at the same time retarding heat penetration and thus strengthening the structure.
' Figure 3 illustrates the combination of Lbituminous material (a) and cells (0) or pockets containing granules or pellets (d) of cellular matter, such as, screened wool pellets, waterproof cellular mineral wool granules, cork granules and the like; also, distributed through this structure, unsaturated fibrous matter 12, such as, excelsior, digested fiax, straw, dry wool, in fact any fibrous unsaturated substance which may impart rigidity when left unsaturated in a surrounding bituminous mass or cellular structure.
An expansion joint as outlined above will have the following properties:
It will resist heat penetration.
It will contain a skeleton structure to give it strength before installation in the crevice.
It will be subject to considerable compression and will re-expand with much less resistance.
It will compress without elongation.
What I claim as my invention is:
1. The method of preparing expansion joint composition, which consists in mixing fibrous material, having inherent rigidity, with bituminous matter while the bituminous matter is at a consistency below that at which it will saturate the fibrous material.
2. The method of preparing expansion joint composition, which cons sts in mixing fibrous material of cellular structure with bituminous matter, while the bituminous matter is of a consistency below that at which it will saturate fibrous material.
3. The method of preparing an expansion joint composition, which consists in mixing cellular material with bituminous matter while the latter is of a consistency below that at which it will saturate the cellular material.
4. The method of preparing an expansion joint composition. which consists in mixing fibrous and granules or pellets of a material having a cellular structure, with bituminous matter, while the latter is of a consistency below that at which it will saturate the cellular material.
