Description
- of bituminous material Patented Jan. 14, 1930 ALBERT G. FTSCHER, OF CHICAGO, ILL INOIS, ASSIGNOR TO THE EHILIP GARE! FACTUBING COMPANY, A CORPORATION OF OHIO No Drawing. Application filed May 5,
This invention relates to composition constructional units composed of a mixture of ductile waterproofing material and animal hair, these units comprising such articles as expansion joint roofing, planking, siding, floor covering, rail filler, protection course for pavin and tne like.
Heretofore it has been customary to manufacture felts, running them thru a saturating vat, pressing out the excess saturation an then coating the saturated felts with an asphalt coating, using a suitable mineral material to prevent adhesion in the process of rolling or packing.
Other methods followed have been to mix the fibres of the felt with the asphalt in a heated state and then roll to the proper thickness while in a heated plastic state. Felt fibres, as known in the roofing art, are ultimate fibres of cotton rags, linters etc., which have no extended binding strength.
Because of the heavier body structure of an expansion joint, and the fact that it must be made up in thicknesses from A, to 1 inch, and in lengths of 5 feet, which are standard up to 15 feet, and from 3 to 12 inches or more in width, it is exceedingly important that the expansion strip have suflicient tensile strength to withstand excess warpage and being poured on eit er side. known in the art.
This invention relates more particularly to.
an elastic compressible body of elongated fibres, especially animal fibres, which are coat ed and pressed into a felted sheet, adding much greater tensile strength thereto than the short fibres, and in this particular instance alludes particularly to the strength of animal hair, together with its unpenetrable nature, its rounded form and adaptability to interlacing, thus extending thru a considerable mass and binding the material together over an extended area, and has to do particularly with the process as described in'the original case in its relation to the paragraph reciting the following:
Another purpose of this invention is to provide a material for the purposes described in may be as elastic binding 1926. Serial no. waste.
sheets with considerably longer fibres than is v i usually provided in soft felt roofing sheets and felts as heretofore manufactured, the fibres of the roofing sheets being very small and short. Thefibres of the material used in the present invention in some instances long as 2 or 3 inches. Flax, hemp, sisal and other vegetable fibres are preferable, although other mineral or animal fibres may also be employed in mixing fibrous matter with bituminous material, taught by me, is familiar with the fact that the mass cannot be formed in a sheet for expansion joint purposes unless the mass of bituminous material or binder is considerably greater than the fibrous material, and proportions exceeding thirty per. cent of fibrous matter are not desirable because of the interference with the binding of the mass, thus making the mass unsatisfactory for expansion joint purposes. This fact distinguishes material for expansion joint requirements as against merely coated fibres, which are made in sheet form forfthe purpose of insulating,

binding material.
Animal fibre is-particularly resilient when mixed with a bulk of bituminous material or material and relates particularly to thoroughly waterproofing the animal hair in the proper mixing contrivance an matting same together under pressure to effeet a continuous sheet suitable for use as an expansion joint and distinguishes as against what is known as a bat of hair felt, known to the art, which is dense by reason of its requirements being primarily for insulating purposes that it is undesirable as an expansion joint, would not be economical because of the tremendous costof treated hair i felt, andbecause the larger volume of the mass is constituted of the hairlike fibres densely matted even in the dry state. This is not the case in the use of animal hair as devised by me for expan ion joints.
Powerful mixers are employed, in which tic, flexible, animal fiber not exceeding thirty heatedasphalt is placed and the animal hair per cent. is thrown into the mixture in the proper pro- Signed at Ch cago, Ill1no1s, this th day portions, thoroughly mixed, and'the entire of April, 1926. mass thus subjected to pressure, in which the ALBERT C. FISCHER.
fibrous material thus coated with bituminous binder is compressed and matted together by passing same thru suitable pressure rolls. This effects a very economical and efiective m expansion joint because the animal hair ex- 75 erts its influence in preventing an excess of rapid oozing of the bituminous binder under pressure, yet in practise the passing trafiic, because of the preponderance of binder, would 15 press the material back into the crevice if any 8o undue elongation occurred. e
e distinguishing feature in this invention is the long filament of animal hair em ployed because of its peculiar functioning 9 and binding power, as distinguished over 85 other vegetable or mineral fibres.
