Description: |
| "The invention relates to hand hammers generally, and more particularly to an improved hammer for sheet metalworking. The general object of the invention is to, provide a hammer especially suited for the various operations, involved in the fabrication and erection of sheet metal structures and which is constructed so as to afford a feeling of balance and a resiliency or bounce that makes it easier and less fatiguing in use.
A more specific object is to provide a hammer particularly well adapted for completing Pittsburgh joints in sheet metal structures, which can be used effectively in confined spaces and which is universally adaptable for seating the driven flanges of either right or left-hand joints or other joint finishing operations such as the lapping over of the second or locking flange."
A family member "reminisce" explains the origin of the tool. Trade journal listings show Hexdall marketing the hammer. |
