In the views A, A; are a series of upright frames rigidly7 mounted upon a common level, and regularly spaced apart. Upon each of these'frames is securely clamped a horizontal tube or sleeve A by means of a suitable cap A2 bolted upon the frame. The mandrel A3 passes through this sleeve without touching.

Upon the opposite ends of each sleeve A are journaled the reels B, B, which rotate in opposite directions, and upon these reels,

rotatably mounted upon shafts ll?, B3, are

the spools B, B3. B3, on which the fabric bands C are stored for use.

The spools (three in number) are regularly spaced upon the reels, and since the fabric bands stored thereon are coated with adhesive material the coils are separated by means of a ribbon C of Holland cloth or y aluminum` or other substance to which the coating will not readily adhere, and when the bands are unwound from the spools, the noiradhesive bands are wound up upon separate spools ll, ll; pivotally mounted'upon thereel and operated to wind up the nonadhesive bands as fast as they are unwound from contact with the fabrio bands by means of the belts B", B5, and pulleys B, B7, upon the respective spool shafts.

The fabric bands pass over pivoted guid-A ing rollers B8, BB, and over adjustably mounted inner guide rollers B", B, to the mandrel A3. and as the mandrel advances, 126 they are laid at a predetermined angle thereon, the movement of the bands serving 'to ro'- tatc the spools B and thereby the spools B* so long as any part of the bands remain on the spools. 130

A are applied tothe mandrel varies With the.

rare mounted upon separate supports B1", r`B1, which are pivoted at B11, B11 for angular adjustment relative to the axis of the mandrel upon radially movable supports e mandrel.

B12, B18. The supports B1", B10 are fixed vin the angularposition desired by tightening the screws B12, B12. `Radial slots B13, B13 in the supports B18, B1B', and screws B14, B14, permlt of adapting the guide rollers'to varying sizes'of cured upon the rings B15, B15, Which'are maderotatablyadjustable upon the reel, by means of the slots B1, B1, and screws B12, B1'I so as to adjust the relative positions` of the bands upon each reel to those upon other reels, so that the edges of parallel bands will not overlap when Wound upon the. mandrel butwill lit closely together, i e

Asmany reels are employed as may be required to produce a fabric of one or more layers and -the rates of speed and revolution of the sets of reels employed in forming the different layers can also be dilereiit if desired. y

A compression lever D (see Figs. 9 and 11), having a handle D and a roller D2 rotatably mounted in the forked extremity D, is secured to the shaft Dtmounted on the reel., The roller D2 is pressed upon the band stored4 on the spool B3 by means of the coledspring D5'adjustably secured to the 'reel'by the 'threaded rod D, nut D1 `and to the leverD upon the shaft D4, `The tension 'upon the spring D, and the pressure of thc roller,D2, is greatest when' the diameter ofthe coil of bands on the spool isgreatest. But ,in this case the pull on the band necessary to rotate the spool B3 has the greatest leverage, and as the diameter of the coil of bands yupon the spool decreases, both the pressure of the roller D2 and the leverage of the band decreases thereby, forming a vpractically constant tension or pull on theand.

e The tension on the band from thep'ressure` roller D2 serves'to prevent the band 4from `getting off the guiding rolls B23 and B2.

,l The means for, rotating the reels on each frame in oppositedirections to interlay the bands as 'described in the `above mentioned Letters Patent are shown `in Figs. 1, 5, 11 yand `12, and comprise change speed gears arranged in trains, one train on each side of the frame.

These supports B12, B18 arese e pulleys B", B7 is shown.

Here a sprmg pressed bar B20 provides In these figures E is the main shaft from i which all the movements of the mandrel and reels are obtained. F, F, F2, F2', F1, F, F6 and F7 are a train of spur gears which provide for the `movements of one reel B' and Gr. `Gr', G2, G3, G4, G5, and G `are a train of gears which provide for the move ment of the reel B in the reverse direction.

`ln Fig. '11 the gear F' is so mounted upon y theiin G8 on the movable arm G2 as to per,- m1 ,of bemg easily removed and anotherk gear,l substituted when a change ot' speed is 85 In Fig. 13 the manner of securing the gears F and G upon the main shaft is shown'.

andin Fig. 161 the mannerA of detachably securing the spools B1, B1 upon the hubs of the friction which enables the pulley to drive the spool but will slip when the tension pro-,

duced. becomes too great, and thus preventy disarrangmg the band. A depresslble spring hook B21 provides a detachablemeans for securing the spool upon the hub of the pulley. f f

In4 Fig. 10 the manner of detachably securing the spools B1 to the reels is shown. Here B2 is the axial shaft, P is a spring` pressed pin slidingly movable in an opening P2 in the shaft. l is a holding dog or latch pivoted in the slotted projecting end of the shaft at l"1 and l" is a flattened' head upon the pin l which engages and holds thc latch firmly in place to retain the spool B, which can be readily released by s'uingingthe pin lf into a. position axial with the shaft. y

'lhe means for propelling the longitudinally movable mandrel are shown in Figs. 1, 5, 17, and 18, and coml'irise the bevel gear M upon the main shaft E the bevelgears M2 and M" upon the short shaft M1', bevel gears M, and M" upon the shaft M1, the vertical shafts or shafts M", MS, having mounted thereon the bevel gears M, M" an d spul' gears M10, M1, arms M12, M1, pivoted on shaft Ml`3 and pin M11 respectively, spur gear h 15 on shalt lV 1G driving' roller M17 mounted thereon. also gear 'MHg pivoted on pin .M11 engaging gear M1 on shaft M20 mounted on arm i 1 and driving roller M21. The oppositely placed rollers M11. and M21, grlp the mandrel A by means ol the tension rod `M22 which is secured ,to arm'vM12 and engaged by arm M12, exerting pressure thereon by spring M2H and .nut-M2"` The speed of rotation of these gripping rollers M and M21, driven by the train of gears, as described, determines the speed of propulsion of the mandi-els. The arm M12 is adjustable for different sizes of mandrels and is locked in place by the screw M25 in the slot M2.

The main shaft E as described furnishes the source of power for driving the mandrel and the reels, and in addition to the adjustments for the control of the speed of the reels the speed of propulsion of the shaft can be controlled by the substitution of other gears for the bevel gears M1 and M", or the gears M and M can be changed to gears ol' larger or smaller diameter it' desired.

In this manner a complete control of the relative rates of speed of the mandrel and reels and of the relative rates or' speed ot the several sets of reels can be obtained, that is the reels employed in winding the separate layers.

Before windingthe fabric bands upon the mandrel it is preferably coated with powdered soapstone or other non-adhesive material to prevent the tube ol adhesive mate rial romsticking thereto. and supplied by means of a receptacle H through which the mandrel passes.

At suitable intervals frames l, I, are provided. upon which guiding and supporting rollers l', l", l'. are mounted equally spaced about the mandrel. A. tube ot adhesive matcrial is next formed upon the mandrel malring the lining for the fabric tubing and is applied by passing the mandrel through the annular receptacle .l which contains the tubing material in a fluid or plastic condition under pressure.

The tubing material (lows under applied pressure through an annular opening formed between a annularlip .l of the receptacle and a screw threaded annular closure .l2 which can be advanced or withdrawn to reduce or enlarge the opening.

The lip J is ot conical 'form and the closure corresponds in shape so that an adjustment of the size oi? the opening can be obtained. i

A lock nut l is ennjiloyed to secure the closure in place.

The mandrel A is formed in detachable sections S as shown in Figs. 1,2, 13, Lt, l?, and 18, which are attached in a progressive or continuous manner. one at a time as 'the mandrel is propelled through the machine.

,The mandrel sections S are united together temporarily by means 'of double ended plugs S prevented from turning by means of keys S2 adapted to it in diametrically opposite kcyways S3 in each end of the sections which are bored out to receive the plugs and are cylindrical and accurately fitted.

-Each plug is provided with an enlarged central cylindrical portion S* which is of the saine diameter as the mandrel and separates the two sections when they are attached together, and its ends formv shoulders vSs against which the mandrel sections closely abut. l f

After the fabric tube is completed on the mandrels it is cut transversely at one of the shoulders S5 and the mandrel sections are then separated. The `length of hose formed upon each section is then approximately the length required for thathosc.

In Fig. 4 one mandrel section is shown att-er it has been detached from the accompanylug mandrel section and the ends closed so that the fabric can be vulcanized. In this figure S, S are closures for the inner openingr spaced from each end and provided with screw threaded openings S7, S". One end of each mandrel section is closedl before vulcanizing by means of a screw threaded rod passing through a flanged plug S", the flange Sw oi which covers that end ofthe mandrel and supports a washer Sn of rubber. A flanged ring S12 is next employed Ato extend over the end ofthe fabric, and the unvulcanized rubber washer or cap S11 is compressed thereby upon t-he end of the hose S.

The parts are finally clamped together by means of the washer S" and nut S15 screwed upon the outer end of the rod Ss. v

ln the other end of the mandrel section the plug which joins the mandrel sections t0- gether is retained and a rod Sm longer than the rod S8 is employed to secure the parts together and asses through a central' opening S17 in the p ug.

A; ring S19 is sleeved over the outer end of the plug attached thereto by a set screw S" screwed into one of the closures S and S20, and serves as a seat for and to compress a rubber washer S upon the end of the hose so that the ends of the hose are sealed at this end with rubber. The similar ring Sl? at the other end has the same function. A nutSn on the rod S1G and washer S22 finally secure the parts together for vulcanization.

To permit the stripping of the hose from the mandrel by means of air or fluid under pressure applied between the hose and man` drel each plug is externally grooved at S'4 for the passage of compressed air, an an.- nular external groove S25 at the side of the shoulder S5 permits the air to circulate around the lug and it passes around the end of the man rel where the clamping ring S" prevents it from escaping at that point. The air is introduced throu h the central opening S17 after-the rod 1 is removed, and screw threads S2 permit the attachmentof. an air pump nozzle thereto. The clamp S" prevents the plug S fram being driven out.

The devices employed for slitting und flat tenin thetubular fabric formed u n the machiney are shown in Figs. 1,15, 6, 8,' 22, 23, and' 24, where Krepresents s circular knife mounted upon a journal bearing K which is vertically adjustable upon a frame T he knife K is` adjusted to bear upon fand cut through the fabric upon the center `line, as themandrel progresses, and is rotatedbymeans of a band wheelK3 upon the A 'fshaft K4. :Since the fabric tubing' when cut l open loses its .frictional contact with the mandrel a separate means yis provided for ,.10 `propel]ing the same and this is shown' to be fafpair of endless propellingchains L, L, one on ,each side of the mandrel. kThe links of these chains are providedv with serrations L, which engage with thefabric.v .15 .The chains areA kept in contact withthe fabric by means of the'guide7bars.L2, L2, which'- are, mounted in the "lidjustable brackets L3, L3, and are ,pressed by springs JL?, L4, as shown in Figs. 2 0 vof pressure being regulated by means of the justed by slots LG, L? and screws L7, L7.

. The chains are propelled by means of 'the sprocket-wheels N, N, anda train of bevelv v.a-ndfspur gears N, N2. N3, N4, N5, N `and jg spiral gears N7 and N8 operated by the main I shaftll. The sprocket wheels N9 are idlers.

Without departing from the spirit of the invention or scope of the claims.

It is also obvious that the rubber or other allies/ive material may be forced through the annular opening, formed by the conical lip J and closure J? by anydesired means, such as a rotating screw 'W encircling the mandrel fitting in an annular chamber and havinga changing' lead, (see Fig. 173)" without de-.
