Blaisdell's Large Variety Molder.
The accompanying engraving illustrates an improved variety molding machine, patented by J. H. Blaisdell, of 107 Liberty street, New York, who is also the inventor of the single-spindle variety molder which is so well known among wood-workers as the Blaisdell Single-Spindle Molder. It is claimed to be the strongest and heaviest machine of its class ever offered to the public, its weight being 2,000 pounds, with table 4 by 7 feet; diameter of journals, 2 1/2 inches, running in self-oiling brass boxes on top, with hardened cast-steel steps floated with oil.
Much difficulty is always experienced in making running parts of machinery at once perfectly firm and at the same time run easy and accurately adjusted. Although this may be accomplished when the work is new, trouble invariably occurs when the parts become somewhat worn. In the present invention the spindles are placed in taper boxes inside the adjustable frame, which is turned to a true and perfect fit, and is raised or lowered by means of a hand-wheel nut with a corresponding thread to that on the spindleframe, as shown in the engraving. In this particular the device is excellent, as it gives stability to the revolving shaft, and at the same time positive and accurate adjustment of the spindle-frame, (which is not the case with the old style hand-wheel and bevel gear, as it is impossible to do away with the lost motion); besides, the spindles are always kept in line and in the same position, which is sure proof that the machine will do perfect woik at all times. The main spindles are 1 3/4 inches in diameter, with three false spindles - 3/8, 5/8 and 1 inch in diameter, fitted by a new and peculiar device never heretofore employed, and on which special claims have been allowed, making the machine capable of adaptation to the lightest or heaviest work, and obviating much difficulty formerly experienced. It is claimed that this molder, from the fact of its frame being cast in one piece, its simplicity, durability, accurate adjustment, and performing every variety of work, is superior to any in the market. Counter-shaft and pulleys are furnished with each machine.
