FLEXIBLE METALLIC TUBE,
APPLICATION FILED NOV. 21. 1904.
UNITED STATES Patented January 31, 1905.
PATENT OFFICE.
THOMAS J. CARROLL, OF HAMILTON, CANADA.
FLEXIBLE METALLIC TUBE- SPECIFICATION forming part 01 Letters Patent No. 780,974, dated January 31, 1905.
v Application filed November 21, 1904:. SerialNo. 283,596. a
To all whom it may concern.-
Be it known that I, THoMAs J. CARROLL, a citizen of'Canada, and a resident of Hamilton, in the county of Wentworth and Province of Ontario, Canada, have invented new and useful Improvements in Flexible Metallic Tubes, of which the following is a specification.
My invention relates to improvements in flexible metallic tubes in which a tin tube hav- IO ing a continuous even bore is provided with a flexible metallic and spirally-jointed covering having outwardly-extending flanges and a secondary flexible metallic strand having inwardly-extending flanges and a fabric packing between said flanges and winding spirally around the flanges and the sides of the flanges of the first cover and around a part of the body thereof.
The objects of my invention are, first, to
provide a flexible metallic tube having an even and smooth bore or interior throughout the tube; second, to provide a tin tube having an even bore or interior throughout and a flexible metallic covering in two parts or 2 5 strands, one said part spirally covering the tube and the other said strand winding spirally around and partially covering the spiral cover of the tube to give flexibility to the tube; third, to provide a tin tube having an 0 even and smooth interior adapted to bend circularly and retain its proper circular shape, and, fourth, to provide a flexible tin tube having an even interior adapted to convey beer, spirits, and other liquids without affecting 5 the taste and quality of beer and the like;
which- Figure 1 is an enlarged elevation of my improved flexible tube, showing the inner tin tube and the next spiral metallic coveringstrand protruding at each end thereof. Fig.
2 is an elevation of the same, showing a part of the outer strand on the upper and the lower part thereof and broken and partially removed from the tube-covering, the tube-covering broken and brought downward from off 5 the even exterior of the tin tube, which protrudes at each end and broken. Fig. 3 is a detail elevation of the same, the outer metallic strand being entirely removed, a portion of the spiral cover of the tube on the central part thereof, and both ends of the said spiral cover broken and unwound from off the end parts of the tin tube. Fig. 4 is a sectional end elevation of the tin tube, which is even throughout its entire length. Fig. 5 is a sectional end elevation of the spiral cover of the tube, showing its outer flange. Fig. 6 is a sectional end elevation of the outer strand. showing its fabric packing and its inwardlyextending flange. The spiral metallic cover and the outer metallic strand referred to have side flanges, as shown. The said spiral tubecover has external side flanges and the said outer metallic strand has internal side flanges. Fig. 7 is a sectional end elevation of the component parts of the flexible tube together and in order through the joining part of the spiral cover of the tube and the outer spiral strand.
The'tin tube referred to has a continuous even and smooth surface throughout the interior and exterior thereof and should be made of pure tin throughout.
The spiral cover and the outer strand referred to are preferably made of sheet-copper.
Similar letters or characters of reference refer to similar parts throughout the several views.
In the drawings the tin tube is indicated by A, the spiral copper cover by B, and the outer spiral copper strand by 'C. The tin tube A is preferably even and smooth throughout its interior and exterior surfaces. The next spiral cover B has outwardly-extending side flanges 2 and spirally Winds or coils around the tin tube A, the body part B of the cover being next to the tube A and hugs the same very closely. The flanges 2 when in position on the tube A adjoin each other when brought together by the flanges 3 of the strand C when winding said strand to position. It is not absolutely essential that the flanges 2 should be in contact and in close proximity to each other. If slightly apart, the flexibility of the tube would be more pronounced. The outer strand C has inwardly-extending side flanges 3 (shown veryfully in Figs. 2 and 6 of the drawings) and is provided with afabric packingl: between the flanges. The body part of the outer strand C, together with the fabric packing 4, winds spirally around the outer part of the spiral flanges 2, and the internal flanges 3- of the strand C fit closely against the sides of the two joining flanges 2 of the spiral cover B, thereby rendering the tin tube A flexible, together with the tube as a whole. hen in the act of winding the cover B spirally on the tin tube A, the body part B adheres very closely and firmly on the tube A by the inherent nature of the copper cover B. The same may be said of the outer strand C in its inherent adherence to the spiral cover B. It will be noticed that the strand C winds spirally and apart and is provided with a fabric packing in its interior and which fits close to the inner body part of the strand and around the outer part of the flanges of the cover to prevent possible leakage should the tin tube become injured by kinks of any kind through improper usage.
VVhatI claim as my invention, and desire to secure by Letters Patent, is-
1. A flexible metallic tube, comprising a tin tube having a continuous and even bore, a metallic cover, spirally Winding around said tube, and flanges outwardly extending from the cover.
2. A flexible metallic tube, comprising a tin tube having a continuous even inner surface, a metallic cover with outwardly-extending and continuous flanges spirally winding around the tube, a metallic strand with inwardlyextending and continuous flanges winding around and covering the flanges of the cover.
3. A flexible metallic tube, comprising a tin tube having a continuous even inner surface, a metallic cover spirally winding around the tube, side flanges outwardly extending from the cover, and continuous therewith, a metallic strand with inwardly-extemling and continuous flanges winding around and covering the flanges of the cover, and fitting on the body of the cover.
i. A flexible metallic tube comprising a tin tube with inner and outer even surfaces, a metallic cover spirally winding around the tube, side flanges outwardly extending from the cover and continuous therewith, a metallic strand with inwardly-extending and continuous flanges winding around and covering the flanges of the cover and a continuous fabrie packing between the flanges of the strand.
