ALBERT C. FISCHER, OF CHICAGO, ILLINOIE.
PBEFORMED RAIL FILLER.
Application filed June 30, 1927. Serial No. 203,678.
My invention relates to a preformed rail I filler comprising a prepared strip of waterproofing material, preferably bituminous material or other suitable binder shaped to conform to the outline of the rail on one side and suitably faced for Contact with the paving on theother side, the strip being adapted to act as insulating, sound deadening and expansion material, deadening the sound of the car upon the rail and insulating the track from the adjacent paving material and taking up expansion and contraction between them..
My invention is concerned more with the substance out of which the strips are made than to their particular form.
One of the objects of my invention resides in providing a preformed rail tiller comprising a waterproofing binder and flakes homogeneously disposed therein,
whereby not only to t in the insulating and sound deadening characteristics of the strip, and also providing an ollicient tlow retarder for the compressible waterproofing binder, but also providing an el'licient structural reinforcing for the rail filler, and in addition augmenting the expansibility and compressibility and sound deadening elliciency of the strip.
These and other objects of my invention will be apparent from a perusal of the following spe il" ation when taken in connec tion with the accompanying drawings, wherein,
Figures 1 to 6 inclusive illustrate various designs of strips which may be used singly or collectively in connection with a rail after the manner illustrated and claimed in an application filed January (3, 1926, by ll. lV. Ilcrbst, Serial No. 79,543.
It is understood that any of the blocks or strips shown in the aforesaid application, or any other type of strip may be availed of, the present invention being concerned with the material of which the rail tiller strips are composed.
1n the present invention I propose to form my rail tiller of a homogeneous mixture of waterproofing material, such as bituminous material, preferably blown bituminous material and reinforcing flakes. These flakes may be any desired type, such for instance as, mica flakes, shale flakes, slate flakes, treated vegetable flakes, treated parchments, papier mach, and other stiffening means in flaked formation, or any type of vegetable or mineral flakes provided they are hat and have perceptible length. Mica is well suited because of the tenacity of the flake, and the fact that the asphaltic material cannot penetrate the mica, nor would the oil be apt to aii'eet it and destroy its stiffening quality, while the stiflcning means in itself would not be subject to decay. There is also a resiliency in layer mica which might be utilized to advantage. Roasted peanut shells or flat, cellularfibrous matter is acceptable, particularly excelsior ribbon flakes, wherein the excelsior ribbon is broken up into relatively long Ilake-like coarseness.
In certain instances I can. incorporate with thetlake elements relatively long fibres which have not only length but toughness and inherent rigidity. Certain of these fibres may be cellular in nature if desired, and they are, therefore, pronounccdly compressible. The pin-pose of the incorporation of the cellular fibres is to secure greater reexpansibility and also to act as an additional strengthening means and to prevent the sagging of the bituminous or waterproofing binder.
T he flakes, and the fibres it'desired, are suitably mixed with the bituminous material when the latter is in a liquid state in a suit-- able power mixer, and the mixture is then preferably rolled, while plastic, according to the process set forth in an application tiled January 29, 1926, Serial No. 84,605. wherein the linear fibres mixed in the plastic bituminous mass are caused to How in the mass and align or stratify themselves lengthwise of the strip to provide stratified, overlapping. reinforcing flakes, or in other words to provide shale-like layers of the flakes within the. bituminous binder, which provides not only a very pronoum'ed rcint'orcing means for the strip, which gives it rigidity, acts as an cfiieicnt llow retarder fothe bituminous binder, but also adds com n'cssibility and recxpansibility and pronounced sound deadening qualities.
In certain instances where the flaked elements are of ccllula r nature I may mix them with the, bituminous matter at a sufiicicntly' low ttllll'HflntlU'tt and for a sulliciently short time to prevent the saturation of the cells of the flakes with the bituminous material, .whe 'by the flakes retain their full c0mpressible qualities. In other instances I contemplate mixing the cellular flakes with the bituminous material whilc in a suiticiently heated condition and for a suflicient length oi time to cause the cells of the cellular flakes to become saturated with. the biluminous n'iaterial.
The formation of my improved. rail filler is somewhat the same as pieces of shale or slate which have partly separated, or resemble in the structure more or less the structure of mica itself, except that the sealing means between the flakes consists entirely of biprovidiag' separately acting strengthening parts, the flakes being distributed thru the asphaltic material in substantially parallel strata, and the majority of the flakes being separated one from another a substantial thickness oi the asphaltic i ieitenial.
:2, A preformed rail tiller adapted as an expansion joint sound deadener and 1nsulatmg material, comprising a homogeneous mixture of bituminous material and reinforcing elements in the form of segregated flakes arranged in substantially parallel strata and in overlapping relation, and separated by a bituminous substance.
A rail tiller comprising a preformed body oi bituminous .naterial having homo geneously distributed theretliru reinforcing flake-like elements arranged in substantially parallel strata, said strip also having dis: tributed tlieretliru linear fibres.
4. A rail filler of the character described, comprising a preformed strip of bituminous material having incorporated therein cellular flakes arrangci'l in spaced apart stratilied lUi'lll and overlapping, with bituminous material between the separate flakes, said flakes having their cells un'penetrated by the bituminous material.
A rail filler of the character described, comprising a preformed strip of bituminous material having incorporated therein cellular flakes arranged in substantially parallel strata and spaced apart, with bituminous material therebetweon.
