MEANS FOR PREVENTING OR REDUCING THE TRANSMISSION 1'0 BUILDINGS OF VIBRATIONS CAUSED BY ROAD TRAFFIC Filed April 15, 1927 Patented Sept. 17, 1929 UNHTEE STATES PATENT OFFICE,
PERCY FRANK SHERGOLD, F, LUTON, ENGLAND MEANS FOR PREVENTING 0E REDUCING THE TRANSMISSION TO BUILDINGS O VIBEAEIONS CAUfiED BY ROAD TRAFFIC Application filed April 15, 192-7, Serial No. 183
The object of this invention is to provide means for preventing or reducing the trans mission to buildings of vibrations caused by road trafiic (which vibrations are especially objectionable where the vehicles passing along the road or street are numerous or heavy) thus eliminating or partially eliminating structural strain.
Accordingto this invention sheets or small blocks of material of a resilient or shock absorbing nature and possessing great durability under conditions of varying temperature and moisture are placed at or below the level of the pavement or road surface, either between the curbstone and the gutter or close to the sunken part of the building, in such a manner that while not normally in compression to any considerable extent they cannot be readily displaced either mischievmisly or accidentally. Suitable materials for the purpose of my invention are rubber, asbestos or compressed cork covered with rubber. Ordinary bricks coated with rubber, and reinforced concrete blocks coated with rubber have also been :lound suitable. lChus the vi brations produced by vehicles travelling on the roadway will be to a great extent intercepted or cushioned by the material.
In order that the said invention may be clearly understood and readily carried into ettect, the same will now be more fully de scribed with reference to the accompanying drawings or diagrams illustrating for exemplilications oi the said invention.
Figure 1 represents in. cross section a roadway having; sidewalks at each side and a house or other building at one side.
liig'ure 2 represents on. a larger scale an alternative arrangement of similar vibration intercepting devices placed under the sidcwalk at the inner side thereof.
Figure 3 represents a modification in which a sheet of resilient material is placed between the sidewalk and the house Hi 42 represents another modification ,986, and in Great Britain September 18, 1926.
in which a block of resilient material is fitted in recesses formed respectively in the pavement of the sidewalk and in an underground part of the house Wall.
Figure represents a resilient component. A represents the house Wall, B thepavement of the sidewalk, C the roadway, D (Figures l and 2) blocks or bricks of resilient material arranged in column alternately with ordinary bricks E or blocks of building stone or the like. The column of blocks may however be all rubber, whichmay if desired be of difierent degrees of hardness in the alternating blocks; or alternatively bricks coated with rubber H as in Figure 5 may be used. The resilient material may in some cases be laid outside the wall in thin sheets as at F, Figure 3, or may be arranged in single blocks G, Figure 4, of somewhat larger dimensions at the ground level along a wall which encloses a cellar or otherwise enters the ground. The inner walls or partitions of a building as well as the outer ones may be provided with such resilient devices. In this case, when the invention is applied to an existing inner wall, the base or underground part of the wall would be laid bare to an extent determined in accordance with the periodicity of the vibrations expected, the wall cleaned and any considerable irregularities of surface removed therefrom, and a layer of a bitumastic compound, rubber ceniient, or composition of a like nature applied to the exposed wall surface. Sheets, slabs, or bricks oi a resilient material or laminated with a resilient material would then be built up vertically against the wall. In the case of using laminated bricks or blocks this would complete the process but when using resilient sheets, slabs, or bricks another coat of a bitumastic compound, rubber cement. or composition of a like nature would be added outside the resilient structure, and an outerwall of cement, bricks,- or any other suitable building? material. built up to enclose the said resilient structure. The screen thus formed becomes an integral portion of the building itself.
It is obvious that the arrangement may be varied in many ways, and should be chosen to suit the peculiarities of any local conditions, having regard to the direction of the vibratory waves experienced.
Vhat I claim and desire to secure by Letters Patent of the United States is 1. Means for intercepting the transmission to a wall of a building of vibrations in an approximately horizontal direction caused by tralfic, wherein laminated resilient materials are built up vertically in contact with said wall, extending below the ground level, and an exterior structure is provided to preserve the formation of the laminated structure, said laminated structure comprising different materials possessing different degrees of resiliency.
2. Means for intercepting the transmission to buildings of vibrations caused by road traffic, wherein resilient materials are built up in a column comprising bricks coated with rubber located below the level of the surface adjacent to the building in such a manner that while not normally in compression to any considerable extent they cannot be readily displaced PERCY FRANK SHERGOLD.
