to the ram body 10 using bolts or similar connectors and reduces the number of parts required for the assembly referring to fig4 and as briefly described above there is shown the boltless bonnet assembly 14 including the bonnet latch 24 the engagement disengagement screw 26 and the bonnet 12 in fig4 the bonnet latch 24 is disengaged from the body latch 22 attached to the ram body 10 the toothed bonnet latch 24 and body latch 22 in addition to reducing the requisite number of parts associated with the boltless bonnet assembly 14 and the ram body 10 advantageously decrease the human operator time and effort required for disengagement of the boltless bonnet assembly 14 from the ram body 10 for example a traditional bonnet assembly where the bonnet is bolted directly to the ram body 10 may require 30 50 minutes or more to disassemble from a ram body 10 this is because each individual bolt must be removed before the bonnet can be separated from the ram body the boltless bonnet assembly 14 of the present invention however may be removed from a ram body 10 in approximately 10 minutes this is because all that is required is to rotate the engagement disengagement screw 26 until the bonnet latch teeth 28 disengage from the body latch teeth 30 rotation of the engagement disengagement screw 26 can be accomplished by any method including for example using a remotely operated device rov referring to fig5 to better understand the spatial arrangement of the components there is shown a perspective cutaway view of a boltless ram blowout preventer according to an embodiment of the present technology as shown the bonnet latch 24 is engaged with the body latch.
