Abstract: In this boiler the furnace and ashpit are situated in the manner common to vertical cylindrical boilers, and as we generally construct it we employ three concentric cylinders, the middle one of which constitutes the main flue immediately above the furnace, and between which and the second cylinder the main body of the water to be heated is contained. The space between the second and outer cylinder forms an exterior fine surrounding the boiler, and within it also are contained tubes leading from the upper to the lower part of the boiler for the circulation of water. Claim: The manner in which we have arranged and combined these cylinders and tubes, as herein set forth, constructing, as we believe, a boiler which is essentially new in its general character.

Manufactured by Great Neck Saw Manufacturers - Mineola NY
Assigned to Metal Engineering Company - Plano IL

The focus of the patent is the lock release which is a hinged segment of the lever handle. The specifications claim this structure generates sufficient leverage to overcome the locking force of the "over center" link. A 1954 METCOID (Metal Engineering Co.) ad for their LEVER JAW E-Z ACTION locking plier wrench shows this style of lock release, but cites patent no. 2,592,807. One known example is marked "GREAT GRIP - EASY ACTION / PAT. NO. 2705899." A 1967 HARDWARE AGE shows this as a product of Great Neck Saw Manufacturers, Mineola, NY. The patent also was used for early 1950s CRAFTSMAN plier wrenches with "EASY OPEN" handles ["CRAFTSMAN" with "circle I" manufacturer code]. The specifications note patent nos. 2,443,153, 2,532,659, 2,543,922, 2,589,511, 2,590,750, 2,592,803, and 2,604,803 as references.
