The rest of the negatives in box 94 are all of the Machine Shop of the Stockton College.
Most likely this was a class assignment. Joel focussed on two pieces of equipment. In both cases, he made sure to include an operator at least in a few images. Gives perspective and intent.
The first piece of equipment slots a key groove in round stock. These grooves receive a spline so they can’t rotate when mated with the receiver. Heavy duty electrical motor shafts have these key slots.
The second piece of equipment is a Kearney and Trecker, a 3HP universal horizontal milling machine, Model 2E. This milling machine must have been very new to the machine shop as this particular model is from 1948/
As usual, Joel makes sure he doubles his shots up to get at least a good one. The above images also show an indexer installed on the horizontal milling machine for more complex operations.
We’ve now looked through some 94 press format black and white images that Joel photographed from 1942 through 1949. The only break was his service in WWII. We’ve seen well over 2,500 images over 163 blog posts, just to give some perspective.
Although there are other press size negatives, these come much later and we’ll talk about possible hypothesis in the next blog post.
