The Fitzhenry machine has also been constructed so as to work in any direction over a fixed table, being driven by a small direct-acting steam-cylinder supplied by jointed pipes. But probably the most perfect scouring and setting machine which has yet been introduced is the Lockwood Automatic Scourer, which may also be regarded as a development of the Fitzhenry machine. This has been some years in use in America with great success, and has received considerable improvements, but has only very recently been introduced into England by Messrs. Schrader and Mitchell of Glasgow, who have kindly furnished the annexed illustration ([Fig. 56]). In this machine the table is fixed, and the tool-carriage can be moved over it in every direction. The large projecting carriage, or cross-head, which supports it, travels on a horizontal rail, which may be observed below and behind the table. Motion is given to it by a screw which is driven in either direction by the pulleys at each side of the cross-head. In a similar way the tool-carriage is traversed forwards or backwards by a second screw at right angles to the first, and by a most ingenious interlocking arrangement both screws are controlled by a single handle. The tool-carriage or "trundle frame" can also be turned like a turntable, so as to deliver its stroke in any direction, the tool-holder being driven by a horizontal crank in the centre of the frame, and immediately above the tools. Though the machine is complicated, and necessarily expensive, it has not been found either in America or Scotland difficult to work or liable to get out of order, while both the quantity and quality of its work are all that can be desired. [Fig. 55] is Gläser's scouring machine. [Fig. 57] illustrates the latest English scouring machine, Messrs. Haley and Co.'s Climax Scourer, which is also ingenious and effective. In it the table instead of the tool-holder is movable by screws driven by belts thrown into gear by a handle, and it is provided with two tables of which one is in work while the hides are being changed and spread on the other. The oscillating tool-holder, instead of being actuated by the rise and fall of the connecting-rod, is moved by an adjustable eccentric.
