Claim 3

A closure cap construction according to claim 1 in which guiding means includes an axial slot provided in said lower cap section and extending radially therethrough and a portion of the body of said upper cap section extending through said axial slot, said axial slot terminating subjacent the upper end of said lower section, and said body portion being deformed to prevent withdrawal thereof through said slot.

Claim 4

Apparatus as set forth in claim 1 in which said latching means includes a deformable element secured to said upper section body, a circumferentially and radially extending slot in said lower section, said element having a tab engageable in said slot, and manually engageable means on said element extending through said upper section body and displaceable radially inwardly to disengage said tab from said circumferential slot.

Claim 5

Apparatus as set forth in claim 1 in which the lower end portion of said lower cap section is internally threaded for attaching the same to said cylinder, and means are provided independently of said threads for locking said lower cap section to said cylinder.

Claim 6

Apparatus as set forth in claim 1 wherein said latching means comprises a spring-pressed latch pivotally mounted at the inside of said upper section and releasably engaging an edge of an opening formed in said lower section.

Claim 7

Apparatus as set forth in claim 1 wherein said lower section is substantially tubular and is provided in the side thereof opposite said guiding means with an opening for gaining access laterally to the inside of the tubular lower section, said latching means comprising a spring-pressed latch pivotally mounted at the inside of said upper section above the lower section, said latch releasably engaging the upper edge of said opening.

Claim 8

Apparatus as set forth in claim 6 wherein said upper section is provided with a recess having a portion of said latch exposed therethrough.

Claim 9

A closure cap construction for cylinders containing oxygen or other gases under pressure comprising a lower cap section of annular form, means on said section for attaching the same to the upper end of a cylinder, an upper cap sectiOn having a tubular body provided with a top wall, said upper section being telescopically axially slidable over said lower section, means for guiding said upper section during said sliding movement, and means for releasably latching said sections against relative axial movement displacement when said upper section is in a downward position on said lower section, said guiding means including a laterally outwardly open channel extending longitudinally in one side of said lower section, and a guide member provided at the lower edge of said upper section, said guide member being slidable in said channel.

Claim 10

A closure cap construction for cylinders containing oxygen or other gases under pressure comprising a lower cap section of annular form, means on said section for attaching the same to the upper end of a cylinder, an upper cap sectiOn having a tubular body provided with a top wall, said upper section being telescopically axially slidable over said lower section, means for guiding said upper section during said sliding movement, and means for releasably latching said sections against relative axial movement displacement when said upper section is in a downward position on said lower section, said guiding means including a laterally outwardly open channel extending longitudinally in one side of said lower section, and a guide member provided at the lower edge of said upper section, said guide member being slidable in said channel.

Claim 11

Apparatus as set in claim 8 together with fulcrum means on said lower section engageable by said guide member, when the latter is slid upwardly in the channel, for swingably connecting the upper section to the lower section and permitting the upper section to be swung laterally to an open position outside of the lower section while still retaining the two sections connected together.

Claim 12

Apparatus as set forth in claim 9 wherein said fulcrum means comprises a fulcrum bar provided on said lower section adjacent the upper end of said channel and extending transversely of the channel, said guide member being hook-shaped and rotatably engageable with said fulcrum bar.

Claim 13

A closure cap construction for cylinders comprising a lower cap section of tubular form and of substantial height to protect a valve mechanism, means on said lower cap section for attaching the same to the upper end of a cylinder, an upper cap section having a tubular body provided with a top wall, said upper section being telescopically axially slidable over said lower section, the lower section and the upper section having cooperating surfaces for guiding said upper section during telescopic sliding movement, said lower section having an opening of substantial size therein extending from adjacent the means for attaching the lower section to the upper end of the cylinder to substantially the top of the lower section for accommodating a hose, said lower section being provided with a pivot receiving slot opposite said hose accommodating opening and extending radially through said lower section from substantially the top of the lower section to the means for attaching the lower section to the cylinder, said pivot receiving slot being closed at its upper end providing fulcrum means, said upper section having a tongue extending radially inwardly therefrom and received in said pivot receiving slot whereby said upper section may pivot about said fulcrum means of said lower section when said upper section is raised to its uppermost position, and means for releasably latching said sections against relative axial displacement when said upper section is in a downward position on said lower section.

Claim 14

A closure cap construction for cylinders comprising a lower cap section of tubular form and of substantial height to protect a valve mechanism, means on said lower cap section for attaching the same to the upper end of a cylinder, an upper cap section having a tubular body provided with a top wall, said upper section being telescopically axially slidable over said lower section, the lower section and the upper section having cooperating surfaces for guiding said upper section during telescopic sliding movement, said lower section having an opening of substantial size therein extending from adjacent the means for attaching the lower section to the upper end of the cylinder to substantially the top of the lower section for accommodating a hose, said lower section being provided with a pivot receiving slot opposite said hose accommodating opening and extending radially through said lower section from substantially the top of the lower section to the means for attaching the lower section to the cylinder, said pivot receiving slot being closed at its upper end providing fulcrum means, said upper section having a tongue extending radially inwardly therefrom and received in said pivot receiving slot whereby said upper section may pivot about said fulcrum means of said lower section when said upper section is raised to its uppermost position, and means for releasably latching said sections against relative axial displacement when said upper section is in a downward position on said lower section.
