A. C. FISCHER EXPANS ION JOINT May 2, 1933.
Original Filed May 25, 1921 Patented May 2, 1933 UNITED STATES PATENT OFFICE ALBERT G. FISCHER, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE PHILIB CAREY MANUFACTURING COMPANY, .A CORPORATION OF OHIO EXPANSION JOINT Original application filed May 25, 1921, Serial No. 472,319, now Patent No. 1,662,567, dated March 18,1928. Divided and this application filed April 14, 1926. Serial No. 101,942.
\ This application is a division of my application Serial No. 472,319, filed May 25, 1921, which matured into Patent No 1,662,567 March 13, 1928.
This invention relates to improvement in expansion joints used for paving and construction purposes, and any situation where expansion and contraction must be provided for. s
This invention relates particularly to a flexible, boardlike structure in contra-distinction to, a rigid, boardlike structure, and .is composed of vegetable fibres of various kinds, such as, flax, hemp, straw or any other to ingredients which may be suitably matte-d together in felted form, or otherwise interwoven as is customary in forming such fibrous material into continuous sheets. This vegetable material may be waterproofed or not,
as is preferred, by injecting therein any bituminous or saturants adapted thereto, thus making the material waterproofbut not destroying the :5 felted, mattedform, which gives to the expansion joint the inherent power of compressionwithin itself and the power to re-expand of its own accord. The use of such fibrous material prevents breakage of the joint, thus a enabling it to be handled in a rough manner and still not be destroyed, whereas all solid bituminous joints, whether provided with felt sides or otherwise, become very brittle in cold weather and a minimum shock breaks or cracks the entire joint. i U
Another object of my invention is to prepare a joint which is lighter in structure than solid bituminous joints, thus effecting economy in transportation and efi'ecting 40 economy in the necessary amount of solid material needed for the expansion joint.
. Heretofore, the solid bituminous joints when under compression inwarm weather have always oozed out of the crevlce a'ndhave been flattened on the pavement by the passing trafiic. so that the bituminous matter could not get back into the crevice, thus making a defective joint. By using a fibrous body of the type described this cannot happen, as the material is both compressible within itself and re-expansive when the pressure is repetroleum waterproofingleased, without oozing out of the crevice. The material of the present invention may be waterproofed, as stated before, and suitably coated in various ways to preserve its body and protect it against the wear of the trafiic.
The particular feature of this expansion joint, as shown in the figure of the accompanying drawing, is that it is a compressible waterproofed material adapted to lie between paving slabs, and of a flexible boardlike nature having horizontal channels or corrugations formed therein, against which the plastic material can mould itself, and after the concrete has set in this moulded form one slab is prevented rising above the other into a wedge formation, due to pres sure or other causes.
The tongues and grooves formed by the plastic mass set against an expansion joint of this shape interlock the slabs, and the joint itself furnishes expansion and contraction means, due to movement of the adjacent slabs under temperature change. This structure is best described in the figure, in which an expansion joint is illustrated composed of terial is compressible and elastic, particular- 1y so when waterproofed with a plastic, ductile bituminous material or like waterproofing substance.
I claim:
1. An expansion joint consisting of a board-like plastic body and flexible elastic compressible means associated with the plastic body to reenforce same,
series of grooves.
{2. An expansion oint conslstmg' of a board-like plastic body and flexible elastic compressible means associated with the plasthe reenforced structure being provided on one face with a F9 tic body to reenforce same, the reenforced tic body to reenforce same, the reenforced structure being provided on one face with a series of parallel grooves.
3 An expansion joint consisting of a board-like plastic body and flexible elastic compressible means associated with the plastic bodyto reenforce same, the reenforced structure being provided on both faces with a series of grooves.
4. An expansion joint consisting of a board-like body and flexible elastic. compressible means associatedwith the plastic body to reenforce same, the reenforced structure being provided on one face with a projection and on the opposite side With a corresponding depression.
5. An expansion joint consisting of a board-like plastic body and flexible-elastic compressible means associated with the plasstructure being provided on one face with alternating projections and depressions.
6. An expansion joint consisting of a board-like body of plastic material and inj, terlaced fibers incorporated in the plastic material for reenforcing same, said body having a tongue on one face and a corresponding groove on the opposite face.
expansion joint consisting of a preformed board-like body of plastic material having one face provided with a groove for interlocking with paving material laid adjacently and in contact with the grooved face of the joint.
8. An expansion joint consisting of a preformed board-like body of plastic material having one face provided with a series of grooves for interlocking with paving material laid adj acently and in contact with the grooved face of the joint.
9. An expansion joint consisting of a board-like body of plastic material and flexible elastic compressible means incorporated in the plastic body to reenforce same, the reenforced structure having one face provided with a groove for interlocking with adj acently laidpaving material.
. 10. An expansion joint consisting of a preformed board-like body of waterproof plastic material having one face provided with a groove for interlocking with paving material laid adj acently and in contact with thegrooved face of the joint.
11. An expansion joint consisting of a preformed board-like'body of waterproof plastic material having one face provided with a series of grooves for interlocking with paving material laid adjacently and in contact with the grooved face of the joint.
