s. B. HAINSWORTH MULTIPLE FLY TEXTILE FABRIC Filed May 6, 1930 Patented Nov. 1, 1932 SYDNEY BEETHAM HAINSWORTH, 0F KINGSTON-UPON-HULL, ENGLAND, ASSIG'NOR TO 3'. H. FENNEB 8t COMPANY, LTD, 0F KENGSTGN-UPON-HULL, ENGLAND MULTIPLE ELY TEXTILE FABRIC Application filed May 6, 1930, Serial No. 450,232, and in Great Britain May 8, 1929.
The present invention relates to improvements in multiple ply textile fabrics which among other uses, are suitable for power transmission and conveyor belting.
Various suggestions have been made to cause a better adherence of a belt to driving pulleys. For this purpose it has been usual to indent the surface of a leather belt or to apply rivets or the like to this with the object of forming suction pockets in its surface.
According to the present invention however, a multiple ply textile fabric belt is woven so that warp on the driving face is brought to the surface to form closed areas enclosing spaces where all the warp is taken below the surface, thus causing the belt and this face to present a series of spaced suction pockets.
The invention is more particularly described with reference to the accompanying drawing in which Figure 1 shows diagrammatically the working face of one form of belt.
Fig. 2 is a weft sectional view correspondin to Fig. 1.
figures 3 and 4: are diagrammatic warp sectional views, on the lines 3-3 and l--4L respectively of Figure 1.
Figure 5 is a sectional view of a modified form of belting.
The warp of a textile belt is brought to the surface along the lines indicated at 1, 2, 3, 4E preferably at least three lines of adjacent warp co-operating in this manner along each line, whilst intermediate these lines of warp, warp threads 5, 6,7, 8 are depressed below the surface at points, such as 9, 10, 11, 12 to form suction pockets wholly enclosed by facing warp on all sides.
In an alternative method of forming suction cups on the face of a belt as shown diagrammatically in Figure 5, a thick weft 13 and a thick warp, yarn or braid is run at spaced intervals under the top ply which is bound down to the other plies at points between pairs of saidthick warp and weft to raise the top ply above the said warp and weft, thus leaving wholly surrounded suction cups Or pockets 14. on the face of the belt.
I declare that what I claim is i 1. A woven multiple ply textile fabric for use as a power transmission, conveyor or like belt, in which portions of the warp on at least one face thereof are brought to the surface to form closed area-s enclosing spaces where all the warp is taken below the surface to form a series of spaced suction pockets.
2. A woven multiple ply textile fabric for use as a power transmission, conveyor or like belt, in which groups of adjacent warp threads in at least one face thereof are simultaneously depressed below the weft for at least one pick, whilst groups of adjacent warp threads are raised above the same weft to form a series of spaced suction pockets completely surrounded by face warp.
8. A woven multiple ply textile fabric for use as a power transmission, conveyor or like belt, in which groups of adjacent warp threads in at least one face are simultaneously depressed below the weft for at least one pick whilst continuous lines of raised warp lie on either side of said depressed warp, thus forming a series of spaced suction pockets completely surrounded by face warp.
4:. A woven multiple ply textile fabric for use as a power transmission, conveyor or like belt, comprising a number of plies formed of warps and wefts, a number of relatively thick warps and wefts distributed at intervals in the ordinary warps and wefts of at least one outer ply and binder threads passing through the fabric and engaging said outer ply at points intermediate of said thick warps and wefts to form suction pockets in the surface thereof.
In witness whereof, I have hereunto signed my name this 17th day of April 1930.
SYDilEY BEETHAM HAINSWORTH.
