Abstract
Abstract An elastomeric hose is encased in a lead sheath and continuously wound in a coil over a drum rotating about a vertical axis, heated to vulcanizing temperature while thereon and leaves the drum in the cured state. The cured hose leaves the drum continuously at a level lower than that at which it enters whereby the lead covered coil drops one pitch with each revolution of the drum such that the position of the hose coil on the drum remains substantially fixed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
An apparatus for vulcanizing elastomeric hose comprising: a. means for axially moving a length of said hose; b. means providing said hose with a lead covering as it is axially moved; c. means to cause said covered hose to move in a helical path about a vertical axis such that the hose enters said helical path at a vertical position above the position at which it leaves said helical path; d. means to heat said hose to a curing temperature while moving in said helical path; e. means to remove said lead covering from the hose after passage from said helical path. f. said means to move said hose includes an enclosure having apertures through which said hose is passed to and from and means within said enclosure to maintain said hose in an annular path while there.
Claim 2
Independent Claim
138 words
An apparatus for vulcanizing elastomeric hose comprising: a. means for axially moving a length of said hose; b. means providing said hose with a lead covering as it is axially moved; c. means to cause said covered hose to move in a helical path about a vertical axis such that the hose enters said helical path at a vertical position above the position at which it leaves said helical path; d. means to heat said hose to a curing temperature while moving in said helical path; e. means to remove said lead covering from the hose after passage from said helical path. f. said means to move said hose includes an enclosure having apertures through which said hose is passed to and from and means within said enclosure to maintain said hose in an annular path while there.
Claim 3
Dependent Claim
58 words
An apparatus as defiNed in claim 1, wherein said means for moving the hose in a helical path comprises an enclosure, a rotatable drum within the said enclosure, and the said enclosure has apertures adjacent the opposite ends of said drum through which apertures the hose is passed to and from a helical coiled condition about said drum.
Claim 4
Dependent Claim
54 words
An apparatus as defined in claim 2, wherein said drum is disposed with its axis vertically and said inlet aperture for introduction of the hose into said enclosure is adjacent the upper portion of the latter and the said aperture for exit of the hose from the enclosure is adjacent the lower end thereof.
Claim 5
Dependent Claim
20 words
An apparatus as defined in claim 2, wherein means are provided for circulating heated fluid to and from said enclosure.
