A recent example is afforded by the machine shown in Fig. 3, designed and built by the same corporation to be used in drawing the common kitchen sink out of sheet steel, instead of casting, as has hitherto been the practice. The machine is remarkable in respect to the size of blank it will work; its great power and strength; in having an engine directly attached for driving, and in many of its features of construction. Fig. 2 gives a general view of the machine, and Figs. 3 and 4 show some of the details of construction and method of operation; Fig. 3 being a side view and Fig. 4 a front view from the left of the machine. The machine consists essentially of a heavy base in two parts, upon one of which is the upright engine for driving, and the clutch mechanism, while from the other portion rise the uprights upon which are the guides for the blank-holder, and which support the crank shaft and other mechanism seen at the top of the machine. The uprights are connected at the top by a heavy beam, which crosses from one to the other above the crank-shaft. They are not subjected to tensile stress during the working of the machine, this stress being borne by the four bolts, which arc 5 in. diameter, and pass through the uprights from the base of the machine to the top, nuts being fitted at top and bottom. The engraving shows the machine with the die removed, but it will be understood that this is secured to the base of the machine between the uprights, and may be of any desired form for the work to be done, and blanks up to 60 in. by 38 in. can be worked. |
