THE ARCHIBALD WHEELS FOR FIRE APPARATUS.
We illustrate on this page the machine employed by the Archibald Wheel Company, Lawrence, Mass., in the manufacture of their Improved Metallic Hubbed Wheels. Few of our readers but have seen these wheels, as nearly all the steam fire engines built in the United States within the past five years are furnished with them. We presume, however, that very few may know why they stand the severest Fire Department service, as none others can. Surely nothing but the best stock known can stand what these do, yet wheels of equal quality stock fail where these stand firm. We take pleasure in presenting, so far as we may, the method of manufacture that centers in this patent press, which may be described as follows :
The machine acts to force into close contact the flat surfaces of the spokes at their inner ends, and thus compact them, so that their faces form true circular planes, upon which the inner faces of the hub flanges rest.
