CONSTRUCTIONAL MATERIAL Filed Dec. 12, 1927 Jae/W:
Patented Aug. 1, 1939 UNITED STATES PATENT OFFICE CONSTRUCTION AL MATERIAL poration of Ohio Application December 12, 1927, Serial No. 239,567
11' Claims.
My invention relates to an improvement in ductile constructional material, especially such constructional material as expansion joint, rail filler, blocks, sheet material etc. My invention relates to the utilization of a water-proofed binder, preferably a bituminous, blown asphalt, although any combination of asphalts may be utilized, a resin, rubber or oil compound, or other suitable waterproofing material as the binder and preponderant material in the mixture. The filler relates to burlap strands utilized as reinforcement, and to accomplish this I take burlap either in bag or sheet form and cut the burlap into squares or other suitable shape with the proper cutting apparatus. I heat the binder to a liquid state and utilize a steam-heated mixer for the purpose of incorporating the burlap sections into the binder, preferably utilizing a kneading machine 20 and then incorporating fifteen per cent of these burlap sections. Burlap is especially adapted for this purpose because the strands readily unravel in the kneading action and separate out into individual strands throughout the mass. I then take the mixture thus prepared and present same to pressing rolls or other sheet forming machines, such as an extruder, and reduce the same to the proper shape and dimension.
I may add finely divided fibrous material to add bulk to the mixture, such as, roofing felt, cotton fiber and other finely divided fiber, and depend upon the strong strands of the burlap for internal reinforcement.
I may simply take a measured quantity of the burlap scrap, from ten to twenty-five per cent, and introduce it into the mixer, or utilize a smaller proportion, any five per cent of burlap scrap and twenty to thirty per cent of finely divided linear fiber, or I may utilize granular fibrous material.
My process relates to the mixing of a waterproofed binder and burlap sections, reducing the burlap sections to separate, individual strands as reinforcing elements in the binder.
45 Referring to the drawing:
Figure 1 represents a section of burlap strands A.
Figure 2 shows a cross section of a constructional sheet having a waterproofed binder B and burlap strands A interspersed therethru.
Figure 3 illustrates a section of constructional material composed of burlap strands A and waterproofed binder B. It is to be particularly noted how the burlap strands appear as veins 55 upon the surface of the constructional material.
Figure 4 illustrates a cross-section of constructional material in which A represents the burlap strands, B the waterproofed binder and C finely divided linear fiber.
Where the material is used for expansion joint 5 purposes I prefer a preponderant binder, ranging from 65 to 80 per cent, the balance being burlap strands and finely divided linear fiber. Where ductility is of less importance in other constructional materials I prefer to use a preponderant finely. divided fiber and a lesserproportion of burlap strands.
I prepare this constructional material by first cutting the burlap bags or sheets into small sections, heating a waterproofed binder, loading same into a steam-heated mixer, adding the burlap sections and thoroughly kneading the mixture until the burlap sections have unraveled and separated from the woven fabric. I then present said mixture to sheet forming means, either in the shape of an extrusion press or pressing rolls, and reduce same to proper form; or I first prepare the burlap sections by cutting up the burlap bags or cloth into small sections, and. prepare a liquid binder, load same into a steamheated mixer and either incorporate the burlap sections or finely divided, linear fiber at different times or the same time, and continue the mixing process until the burlap fabric has been separated or been shredded into individual strands and dispersed itself thru the mixture.
I then present same to either an extrusion machine or pressing rolls and reduce same to the proper form.
The burlap sections are produced from bags 85 which are available on the market and unfit for use otherwise, or other burlap or closely woven fabric of various kinds which readily unravel from the woven state. I depend upon the adhesiveness of the binder and the pulling apart thereof, as well as the kneading action of the machine in separating the individual strands from the woven state. The finely divided linear fiber may be in the shape of cotton, cotton linters, roofing scrap, waste felt, or other materials containing short length and individual fibrous elements. I thus secure a combination of long strands ofhemp or jute, from which the burlap bags are made, and finely divided fiber.
I claim:
