This is, in fact, three separate lines, each having an independent engine,but all so arranged that by means of friction cut-ofF couplings the three lines canbe connected into one, and driven by either of the engines. It will be noticedthat these lines are supported and their clutches operated by the pedestal-bearing,floor-stand, and shifting device more fully shown in Plate No. 261, on page 325. Wm.

The special feature in this view is the mounting of the receiving pullej ona sleeve or quill, which is entirely independent of and apart from the lineshaft which runs through it. The two are connected or disconnected by a frictioncut-oflT coupling, so that either can be in motion while the other is at rest, andneither will be exerting any wearing strain upon the other. 338 Wm. Seli,ers & Co., Incorporated, Philadelphia, Pa. Injectors. IN i860, the exclusive rights for the manufacture of the Giffard Injector in thiscountry were obtained by our House, and constructive changes were intro-duced to increase its durability and efficiency and to adapt it to Americanpractice. The most radical of these changes was due to the invention, by WilliamSellers, of the self-adjusting combining tube. This improvement was the chieffeature of our Injector of 1865, which passed through a number of subsequentmodifications, and found its final development i
