FLEXIBLE HOSE Filed Janfz, 1957 5 LLQ l Of/L.
G. KAKA/4Q 2,870,619 y FLEXIBLE HosE John Greczin, Philadelphia, Pa., assigner to Fidelity Machine Company, Inc., Philadelphia, Pa., a corporation of Pennsylvania This invention relates to exible hose, primarily of garden type, the invention having application to all types of hose employing knitted fabric as a wall-reinforcing medium. y
One object of the invention is to provide a hose of the broad type set forth exhibiting an extraordinarily high burst strength conferred by the peculiar and novel character of the wall-reinforcing fabric.
Another object isv to provide a hose wherein superior burst strength may be achieved without increased pro duction cost.
Still another important object is to provide a hose composed of transparent plastic and containing a knitted reinforcing fabric which shall be characterized by a desirably ornamental appearance.
A further object of the invention is to provide a tubular knitted fabric which by reason of certain inherent structural characteristics is capable of conferring the several aforesaid advantages when employed as a wall reinforcing element in hose.
In the attached drawings:
Fig. 1 shows a section of hose composed of transparent plastic and containing a tubular knitted fabric according to the present invention;
Fig. 2 is a sectional view on the line 2-2, Fig. 1, and
Fig. -3 is a diagrammatic development of the tubular reinforcing fabric shown in Fig. 1.
With reference to the drawings, the reference numeral 1 indicates the plastic tubular wall of the hose which is transparent in the present instance to expose the embedded tubular knitted fabric 2 which constitutes the wall-reinforcing medium. As clearly apparent in Fig. 1 the fabric 2 departs from the conventional in several respects including the relative widths of the Wale loops relative to the lateral spacing of the wales and the characteristic crossing of the strands in the spaces between the wales.
The structural form of the fabric is 'shown in detail in Fig. 3. The fabric is composite of two tubular fabrics knitted from separate yarns and separate sets of needles. In their cylinder or cylinders the needles are arranged so that those of one set alternate with those of the other set. Consequently the walesof one fabric component alternate with the wales of the other component. In the drawing, the wales of one component are identitied by the numerals 1, 2 and 3, and those of the other component by the numerals 4, 5 and 6. The loops 7 of the wales 1, 2 and 3 are aligned coursewise with the loops 8 of the wales 4, 5 and 6. Each of the sections 9 of yarn which connects the loops 7 in the adjoining pairs of the wales 1, 2 and 3, instead of extending coursewise across the intervening wales 4, 5 or 6, as the case may be, is diverted to the next adjoining course in order United States Patent()l ice I Patented Jan. 2,7, 19,5 9
of'ffo'rmation and inthe latter course is tucked behind the pbasev of the loop 8 of the said intervening wale. Each of the sections 11 of yarn which connects the loops 8 in the adjoiningpairs of the'wal'es 4, 5 and 6 is similarly diverted from a normal coursewise path across the intervening wales 1, 2 or 3 to the adjoining course and in the latter is tucked behind the base of the loop 7 of the said intervening wale. This is shown clearly in Fig. 3 wherein the one course is indicated by the reference numeral 12 and the succeeding course by the numeral 13.
With this formation the yarns 9 and 11 of the two fabric components are crossed diagonally between theadjoining wales of the composite fabrics and in the present instance the individual crosses are confined to and are aligned with the individual courses of loops. This is a preferred arrangement for reasons hereinafter appearing.
In accordance further with the invention, each of the loops 7 and 8 is made abnormally wide coursewise, and in the present instance the width of the individual loop is approximately equal to its length. Preferably and as illustrated, the width of the loops 7 and 8, and therefore of the wales, is approximately the same as the spaces between adjoining wales occupied by the aforedescribed crossed yarns, so that the interstices of the composite fabric, i. e. those embraced by the loops 7 and 8, and those defined in partby the crossing yarns 9 and l1, will approach uniformity. By this means the fabric is made to exhibit a substantially uniform strength throughout particularly in its function in the hose to resist radial expansion due to internal fluid pressures. Also the lines defined by the Walewise portions of the wale loops are substantially uniformly spaced around the entire circumference of the hose, and this coupled with the presence of the crossed yarns previously referred to in the spaces between the wales tends to preserve the wall of the hose in its original true cylindrical form against both internal and external pressures.
It will be apparent that for any given strength, a fabric of the uniform properties described above will require a lesser weight of yarn than one wherein a lack of uniformity entails use in all parts of a weight of yarn adequate to give "the required strength in the weaker portions. In this respect, therefore, the invention affords a material economy in hose production. The invention achieves also a fabric pattern of improved appearance which is a factor of importance in hose composed of transparent plastic, as set forth above.
I claim:
l. A tubular knitted reinforcing fabric for flexible hose, said fabric being made up of individual mutually overlying knitted webs relatively arranged so that the wales of one web lie in parallel alignment with and within the spaces between the wales of the other web and with the Wale loops of both webs in coursewise alignment, the yarn connecting the loops of each adjoining pair of wales of each web in any one course being tucked behind a loop of the intervening Wale of the other web in a succeeding course so that in the spaces between the wales of the said fabric the yarns of the v Webs intersect each other on lines diagonal to the said coursewise direction.
2. A tubular knitted hose-,reinforcing fabric according to claim 1 wherein the said wale loops have a course- Wise width approximating the coursewise width of the spaces between the wales of the fabric.
3. A tubular knitted reinforcing fabric for flexible hose,
3 said fabric being made up of individual mutually overlying knitted webs relatively arranged so that the wales of one web lie in parallel alignment with, and within the spaces between the wales of the other web, and with the Wale loops of both Webs in coursewise alignment, said Wale loops having a coursewise width approximating the coursewise width of the spaces between the wales of the fabric, `the yarn connecting the loops of each 'adjoining pair of wales of each web in any one'course being tucked behind a loop of the intervening Wale of the other web in the next succeeding course, so that in the` aetzols spaces between .the Wales of the v.said fabric, the yarns of the webs intersect each other on lines dagonalto the g said coursewise direction.
