With remarkable exactness the emery wheel has been described as “a rotary file, whose cutting points never grow dull; and what the circular saw is to the hand saw, the emery wheel is to the file."Nay, more than file, or saw, or grindstone, for numerous uses, inasmuch as it is immaterial whether the application be wet or dry, coarse or smooth, the emery wheel is equally, and under all circumstances an easy, cheap, and quick
mode of surfacing or grinding down metals. Slack's Emery Wheel and Machine Co., Limited, Lime Bank Works, Ashton, Old Road, Manchester, are the manufacturers of the improved patent consolidated emery wheels, and they are likewise of eminence in the engineering world as the manufacturers of improved emery wheel machinery. By them the grains of emery are consolidated into wheels of all sizes by a special composition and process. He was a great benefactor to his kind, and a true friend to all workers in metals, who first devised this method of vastly enhancing the cutting powers and also the durability of the material. But is not the emery wheel another illustration of the old Cornish axiom, that “there is tin for all time, though not for all men?" Before the world had the great engineering concerns, and the vast foundries which are characteristic of modern times, the grindstone and the file answered men's purpose; but with the occasion came the tool, and the emery wheel followed upon the steam engine, which was at hand to rotate it.
The worker in the useful metals, who does not yet possess an emery wheel, is indeed in the rear. The more the progress which the foremost of his order make, the more hopelessly he is struggling in the backwater of that progress. To attempt to compete with the American manufacturers in numerous processes will he certainly attended with discomfiture; to attempt to compete with many manufacturers who are his own countrymen will with equal certainty result in unsuccess. Much keener in its cutting powers than anything at present known, the emery wheel is made of all diameters up to 36 in., and from i in. to 6 in. in thickness, and it can be turned to any shape that may be required. Machinery and castings, implements and tools of whatever metal, and of whatever hardness, can be fretted by the emery wheel into any shape desired. For cutting brass special wheels are made.
As the brilliancy of the diamond is greatly increased by its setting—and diamonds are necessary for the turning of the emery wheel—so the efficiency of the emery wheel depends in much part upon the machinery in connection with which it is made to operate. Engineers and metal workers have great cause for satisfaction that the company we have named have made not only emery wheel, but likewise emery wheel machine making peculiarly their own. To the Lime Bank Works resort may now be had by anyone requiring emery wheels suitably set in appropriate machinery, whatever may be the duties which it is designed the wheels shall fulfill. And the buyer may resort to them with all the confidence with which one is accustomed to consult those who have made any branch of science or manufacturers their especial study, and in that branch has won distinction and fame.
We illustrate three out of the many emery wheel machines, which, from our own knowledge of their excellence, we are able readily to commend to buyers.
No. A machine should have a very wide constituency of buyers; for it is a simple and very useful application of the 1 wheel to the general purposes of a fitting shop. It will at once l appear that it can be readily fixed on a bench or other convenient stand. As the manufacturers explain, it is fitted with 1¼ in. steel shaft, extra long bearings, lubricators, adjustable rests, pulley, &c. The two wheels shown upon it are those known as improved consolidated. They are of the 12 in. size, one is 1½ in., and the other 1 in. thick. Especially adaptable to the fettling and the dressing of castings, and to the filing up of wrought iron forgings, it is to be had at as low a figure as £6 10s. Only £1 more is needed to purchase the same machine fitted with two 14 in. wheels, one of them 2 in., and the other 1 in. thick.
The roller machine has been devised for bush bearing, or fulcrum grinding. It is fitted with five emery rollers, 6 in. long, assorted from 1 in. to 3 in. diam., and one wheel 5 in. diam. by 2 in. wide. Of this the price is £7 10s.
No. AA machine, on stand, and with countershaft, pulleys, and strap motion, is certainly in this especial class the most convenient and complete arrangement, since it enables the speed to be obtained without any difficulty. No. AA has all the apparatus and wheels described in respect of No. A. Its price, complete as we illustrate it, is £12 10s., or £13 10s., with the two 14 in. wheels of 2 in. and 1 in. thickness respectively. |
