When it comes to steam locomotives, "gearing" became an important consideration. It's usually done with drive wheel diameter. Locomotives with smaller diameter drive wheels were primarily used for pulling heavy freight trains or for yard switching, where as the large diameter drive wheels were typically utilized for passenger train service.
The heavier freight trains needed more pulling power, so smaller diameter drive wheels (and more of them) was the answer. The added locomotive weight provided more "tractive effort" (or traction). Passenger trains were faster than freights, and needed larger drive wheels...
This group of glass plate negatives was owned by someone who owned or worked for a company that imported straw plait, (used to make straw hats)or a hat manufacturer. The negatives are all held apart by old forms from Maclay & Co. Straw Plait Exporters to America and Europe, who imported from Tientsin, China. The forms are dated 189_, and at least 2 of the photos were taken between 1925 and 1932 so he was using up scrap paper he had saved for about 30 years. The photographer was interested in aviation. He took photos of a plane that was used in Byrd's Antarctic expedition, a Ford Trimotor, possibly the Floyd Bennet, and Eddie Stinson, an early aviator. A note saying" He flies with a straw hat" is still with the negatives. There are also pictures of factories and a group of Chinese men, who must be business partners.

That house was moved there. My only question is: Why? I'm also curious to know what the banner across the porch says. I would really like to see the completed project...if that ever happened.
Lewislynn, I blew up my original picture of the negative, and the banner is readable, and I actually found info about the John Eichleay Jr.Co. from Wikipedia In 1875, an innovative building inspector named John P. Eichleay, Jr. founded a structural moving business that would soon become renowned for completing projects believed by many to be impossible. The advent of the industrial age brought with it profound changes in urban landscapes of America. This transformation was perhaps no more evident than in John's hometown of Pittsburgh, Pennsylvania. As the preeminent center of industry and technology at the time, small houses and buildings were being torn down to make room for larger ones, industrial plants were pushing residential neighborhoods outward from the rivers and railroads, and street railways permitted people to live further from their places of work. Believing that structures could be moved for only a fraction of the cost of demolishing and rebuilding them, John felt that all of these factors made for a lucrative business. They did! Although the projects undertaken during the early years were quite modest, they became increasingly bold and impressive as techniques were perfected and the reputation of the company grew. [1] In 2002, the firm was placed into receivership due to financial problems. Split into two divisions, the assets of the firm were purchased by SNC-Lavalin and Pittsburgh-based S/D Engineers.[2]
Thanks for that. That is very interesting. It's a wonder the company lasted that long if there were many of those kinds of jobs.
