Spray apparatus for metal forming and glassware forming machines

Claim 2

A lubricant spraying apparatus for metal forming and glassware forming machines of the type having a forming cavity into which the material to be formed is placed, and a plurality of nozzle means arranged to discharge fluid lubricant into the cavity prior to each forming operation such that the walls of the cavity and parts associated therewith in the forming operation are properly coated with the lubricant, said apparatus being comprised of, a spray ring means which is positioned generally around the opening of the cavity, said plurality of nozzle means being positioned on the spray ring and being operative to discharge fluid lubricant into the cavity in a helical tangential flow pattern, conduit means for connecting the nozzle means and spray ring means to a source of fluid lubricant whereby a predetermined amount of lubricant can be supplied to the cavity at desired intervals of operation.

Claim 3

Claim 4

The apparatus according to claim 1 wherein, said nozzle means also operate to provide a lubricant coating on a punch member associated with the cavity which is used to knock out the part after it is formed.

Claim 5

The apparatus according to claim 1 wherein, said nozzle means are comprised of at least three or more nozzles positioned generally on the inner periphery of the spray ring means.

Claim 6

The apparatus according to claim 1 wherein, said fluid lubricant is inter-mixed with air such that the lubricant when sprayed through said nozzle means operates to generally uniformly coat the lubricant on the desired surfaces inside the cavity.
