' i This invention relates .to a horizontal Ltype ofumachin e ifor WIZLPPlIlQ gummed fabric aboutsafbead such as Scam constructing pneumaticv tires.

It is an ob'ect of this invention.'to provide "amachineof the class Eidenti'fied eapa-ble 'of rapid operation Without. handlingfithe ifabrio' on:its coated side.- I I It is also: anobj ect OfitlllSdIlVBlltlOIl to providexa special form of folder "that will auto matically bend the fabric about the sides of the bead. a

It is:a further object of thisinvention to provide amachine whereinfhalf-of the operating parts are arranged as a work'supporb. mg surface,the remalmngparts beingadapt ed'ito be simultaneously brought against'and lifted fromi'theworking surface.

It is another object of this invention to "provide a motorfdrive with a sensitiveiicontrol'by the operator. I i

Figure? is a fragmentary detail of the {friction driving mechanism.

'Asshown onthedrawings': This machine was designedto wrap a strip of rubberized fabric around the bead *ring or corefor an automobile tire,-in su'cha wayas to leave flipper strips projecting at the de-.

sired angle tobe built directly-into a tire carcassj The machine porting a vertical shaft IS carrying a frio tion disc'14. An electric motor is mounted is an enlarged section onthe line proper comprises "a tablelO with suitable legs 11 and a low shelf 12 sup-- onralbalanceplate 16 carried bya shaft 1'7-t0 whicha foot lever 18 is secured. "The motor is provided with a friction'pulley 19 to engage the disc l twhen the foot lever is deis necessary because oftheveryrtacky nature of the rubberized. fabric and bead "handled by the machine.

The upper end of the vertical shaft 113 pr-ojectsabove the topv of theitable and carries a gear .19 which meshes with a larger gear20 secured to a fluted bevel wheel 21 rotating about a tube 22iprojecting down'lthrou'ghthe table top for a purposeto bebroughtouthereinafter- For the sake oford'erliness in rth'e presentation of the subject, the various ifeatures of the machine will, be :taken up in the orderthey affect the work. i

A flanged .roller'23 is adjustablyimounted in a bracket 24. This roller feedsthegummed fabric under the bead, and the flange on the roller determines the overlap between the two edges ofthe fabric after it has been wrapped aroundthe bead. AZSIIIZLll-IOHBI 25 The "motor is so arranged that its above theifianged roller conformsito .theshape of the bead and presses the head into ifirm contact with the fabric passing over the flangedroller 23. Theroller 25 .i-smounted on one end of a bar 26, the other end of which carries .a folding plate27. From the rollers 2 iand .25, the bead, pullingthe fabric which has been tacked thereto on the undersideby the previous operation, enter-s ahemmer or folder comprising asupporting plate 28 below the fabric, a bracket-29 secured :there'to having a series-of rollers 29 andan initial I rake 3Oto lift the fabric inside the bead .into

contact with the vertical inner edge thereof and finally the folding p1ate27 which bends 'over the upstanding edge of fabric into contact with the top of the bead into a shape suOhasshOWn in Figure 5.

From the folder, the bead and enoompassing fiipper strip pass to the power driven fiuted bevel wheel 21. Because ofthegreater circumference of the edges of the flipper strips as compared to the bead diameter, the edges must be stretched to cause them to ice flat in a position to be built into a tire carcass.

An idler fluted wheel 32 meshes with the fluted wheel 21 to perform this stretching operation. The two fluted wheels intermesh like gears to stretch the fabric over the convolutions, or if desired separate gears may ,Above the arm a spring 37 and nut 38 serve to give an elastic load on the arm when the rod is drawn downwardly by an eccentric 38 on crank operated shaft 39 below the table. When the rod is pushed up, it lifts the arm and the fluted wheel 32 to allow removal of the completed bead. The bar 26 also has a downwardly projecting rod 40 actuated by a cam 41 on the shaft 39 which serves to lift the roller 25 and folder off the bead simultaneously with a similar movement of the fluted wheel 32. A spring 42 serves to give a proper working pressure on the bar 26.

In am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. A bead flipping machine comprising a pair ofrollers adapted to cause initial contact between the bead and fabric on one side of the bead, means for folding the fabric into contact with the other sides of said beads and a pair of fluted wheels adapted to stretch the outstanding edges of the fabric into a smooth surface.

2. In a bead flipping machine, a pair of fluted bevel wheels adapted to stretch the edges of the fabric into a smooth flange, and means for driving one of said Wheels.

3. In a bead flipping machine, a longitudinally adjustable flanged roll for feeding the fabric beneath the bead, a folder comprising a supporting plate, a bracket secured thereto adapted to lift the flat fabric into a vertical position in contact with the side of the bead, and a folding plate adapted to bend over the vertical fabric into contact with the remaining side of the bead and with the other or fiat edge of the fabric.

4. In a machine of the class described, a pair of fluted bevel wheels adapted to stretch and pull the material through the machine,

and a folder for folding the material about a bead.

tioned between said plates for engaging the portion of the strip applied to said first mentioned side of the bead.

6. In a bead wrapping machine, means for applying a strip of material to one side of the bead, and means for folding a margin of the strip over. said bead comprising a folding plate, and a roller having its axis disposed at substantially right angles to said plate for engaging the portion of the strip applied to said first mentioned side of the bead during said folding operation.

7. In a bead wrapping machine, means for applyin a strip of material to one side of the bea and means for folding the margins of said strip over other sides of said bead comprising a pair of spaced folding plates for engaging said marginsand a roller positioned between said plates for engaging the portion of the strip applied to said first mentioned side of the bead, said plates including parallel and laterally projecting portions ex-- tending diagonally from said roller.

8. In an apparatus for beads, means for supporting and rotating the beads, and means for applying a strip of fabric to the inner circumference of the bead and turning devices for the margins of said fabric comprising two spaced substantially parallel plates arranged to fold said margins over the sides of the beads.

9. In an apparatus for'beads, .means for supporting and rotating the beads, means for appl ing a strip of fabric to the inner circum erence of the bead and turning devices for the margins of said fabric comprising two spaced substantially parallel plates arranged to fold said margins over the sides of the beads, and means for rolling the margins of the fabric into adhesive contact With the sides of the beads.

10. In an apparatus for beads, means for supporting and rotating the beads, means for applying a strip of fabric to the inner circumference of the bead and turning devices for the margins of said fabric comprising two spaced substantially parallel plates arranged to fold said margins over the sides of the beads, and a roller positioned between said plates for holding the fabric in engagement with said circumference of the bead during the folding of said margins of the fabric.

In testimony whereof I have hereunto subscribed my name at Cudahy, Milwaukee County, Wis, Nov. 12, 1928.

EDWARD HUTCHENS.
