FLEXIBLE INTERLOCKING SPRING-TUBE.
Application filed may 12, 1913, Serial No. 767,200. Renewed August Interlocking Spring-Tube, of'which I hereby declare the following to be a full, clear, and exactdescription, such as will enable others skilled in the art to which it appertains to make and use the same.
The object of the invention is to provide a flexible spring tube or casing provided with interlocking coils which can also be employed as a simple and easily applied form of armor for hose pipe, such as a pneumatic'orrailway brake hose, and a pressure or suction hose of all sorts.
.The invention also provides a. form of tube composed of overlapping and interlocking elements and in "hioh the joints are practically .waternnd dust proof.
The invention comprises the combination of the ,coils or turns of a spirally wound wire'or band enlarged and having preferably rounded edges arranged at ditfcrent levels, and in which the enlarged edges are I connected by a thinner web or member, with an adjoining coil or turn similar in shape and C(ll'lSillllCtl'OIl and in which the ei'ilarged edges interlock with those of the first named coil or turn. All the interlocking coils or turns may be component parts of one integral coil, or the tube may be composed of a multiple number of coils. The invention comprises the combination and arrangement of parts to permit of a limited amount of stretching and compres sion of the coils upon each other, and further consists in the details of construction, hereinafter described and shown in the drawings, and specilically pointed out in the claims. H
In the accompanying drawings Figure 1 is a longitudinal section of a hose incased by this tubular armor and bent into a curve h owing the action of the component parts of the armor u on each other in expansion and contraction; Fig. 2 is a side elevation of a portion of the interlocking spring tube showing a method of formation and of constructing the interlocking joint; l ig. 3 is an enlarged section of a portion of one side of a straight piece of interlocking spring tube showing a portion thereof completed; Fig. l shows the interlocking spring tubc Specification of Letters Patent.
' interlocking with the same, and
side of the curve and to outer side oi the curve, but the tube as a Patented Mar. 23, 1915., 19, 1914. Serial No. 857,607.-
' as applied to the exterior and interior of a.
flexible hose fabric.
In these views Ads a band of metal or other suitable substance preferably formed with a body or stem portion 1 having forked extremities 2, 2, integrally connected together. The extreme edges of the body portion and forked extremities are enlarged at 3, 4: and 4, respcctively'arrd also pref-' erably smoothly rounded to permit (if the easy action of one coil upon anotherl 'when they are associated together in the.completed tube In Fig. 3 the manner of interlocking the coils together is shown clearly, the enlarged edge of the body portion of one coil being inclosed between the forks of the next adjacent coil, thus allowing only a predetermined amount of lateral or longitudinal separation of the coils. The enlarged extremities 4, 4', are shown upon different levels, and each extremity 4, l is at a different level from the extremity 3, which is inserted between the extremities 4, 4:, thus preventing the complete separation of the coils, under working conditions.
.A limited movement longitudinally of the hose is permitted by giving a predetermined width to the web forming the body portion 1, and to the webs forming the forks 2 and 2. This limited movement is essential to permit the flexure of the hose as shown in Fig. 1, the coils being permitted to approach closely to each other on the inner separate at the whole is only slightly extensible as predetermincd accmrding to the amount of flexibilit v required, nor can the coils become entirely separated, since it is not desirable. to have the tube stretch unduly or torted in such a. manner as to be impracticable or decrease the life of the hose or other substance inclosed therein.
The bands with their enlarged .ends are magnified iii-size in the drawings and the actual bands can ordinarily be constructed by drawing them through dies having openings of suitable shape, or by passing through suitablv shaped pressure rolls. AtC and D,
Figs. 2 and a form of F shape is shown which is suitable for this purpose. The edges and 4 lie in their proper positions become dis loo . 3 upon the adjacent coil, While the coils being wound upon the mandrel, as shown is dotted lines in 3. In l ig. 2 l5 is si'icli e mandrel and the edge 4: is shown at G being formed over the edge 3 upon the body portion. in Fig. 4.: the tube is shown applied as e protective casing both to the interior and exterior of o llexible hose or other suitable materi l which may thus be used for section purpo the hose fabric being protected by the. inner flexible metallic tube from the matter passing therethrougli, and the outer ornior shielding the exterior of the hose from injury. 'lhis inner :liexible tube also serves to prevent collapsco't' the intermediate fabric when in service for suction purposes,
1 do not confine myself to the use of this flexible poses clone since by the introduction oif suitable elastic and adhesive substance Yen at H in Fig". 5, among the interlockcoils ri. thereof, the tube might constio complete tube or hose in itself with lin' or eorering of any sortv A (:lizin'l lined between the forks in euch coil .nich the said elastic substance is,in-
closed. Tl his material can be introduced l are being; constructed upon the mandrel.
The above described coils being made of spring material will always resume their origimrl positions when the tube is elongated or flexed, and hence no cramping or binding of the ports on themselves will occur under ordinary conditions.
Having thus described the invention Whzit l cliiini new and desire to secure by Lettors Patent is:
i In 21, flexible armor, a coiled bend hav- Webbed body portion with an en-- i terlocliing spring tube for zirinor one the aforesaid chamber While the coils lerged single edge, and an integral webbed l'orli, extending from the opposite edge thereof, said fork provided with enlarged edges the enlarged edges of the fork in one spiral coil ot'suid bend inclosing betvwen .tlieni the enlarged edge of the webbed body portion of the adjacent coil. V
5%. .ln :1 flexible inetnl armor, a coiled bond comprising a tnvebbed body portion and fol-lied eiitreiiiities, and enlarged edges for said webbed body and l'iorhetl extremities, the said torkeih extremities inclosing; the body portion of the adjacent coil between them, said enlargedsedges of said iorlied portions of one coil adopted to emerge and ioclose the enlarged edge of the bod portion oi the adjacent coil. 9
