The view shows the hoist in the act oflifting an engine truck center casting. Aswill be noted, the cylinder of the hoist isbolted to one of the pillars, and pullsdown on the chain; it is made of seven10 x 14-inch coach-brake cylinders, whichhad been discarded on account of brokenflanges. These cylinders are arranged inline, and held together by rods, with nutson each end. As you will see, this makes a cheap,convenient and powerful hoist, with about8 feet lift, and is an example of what can old material w-as used; and they are muchadmired. For the benefit of any wishing to makeuse of such cylinders for this purpose, Iwill state t
