[...] of Trade will make an effort to have the works locate here.”{Reference:The Leetonia Reporter, August 9, 1894, 1.} A week later, a front page story in the Leetonia Reporter gave in detail an account of the deal worked out to entice the new company to locate their business in Leetonia rather than Columbiana. In exchange for locating in Leetonia, the Leetonia Board of Trade would donate a site, picked out by the owners of Crescent, for the new business. The three partners selected a tract of land located on Front Street with railroad tracks on the rear of the property [...]
[...] The Universal Grinding-machine
Universal Grinding-machine
This machine (Fig. 9) has importantly modified machine-shop practice, as by grinding it readily gives an accuracy in finish previously considered commercially impracticable, and, moreover, demonstrates that most conical and cylindrical surfaces, soft or hard, can be better and more economically finished by grinding than by any other process. In many kinds of work it takes the place of a lathe, which it supplements by finishing other work previously roughed out. It does both internal and [...]
[...] Both spindles are driven at the same speed, by one belt, with ten variations in speed, ranging from 9 to 32 revolutions per minute. The spindle heads are adjustable, horizontally, to and from the table and can be set to a minimum distance of 4 inches and a maximum distance of 48 inches between the ends of the spindles. The table has a longitudinal screw feed of 48 inches, is carried by a vertically adjustable knee providing 11 inches vertical adjustment, and the rate of feed can be varied from 1 to 6 inches per minute.

Mann & Charlesworth, of Leeds, possesses several novel features.

This enables one eccentric and rod to do all that is required in working expansively when running forward or backward, and for reversing the [...]
[...] electric current increases as the square of the current. For example, suppose the normal current is 9 amperes and is increased to 10 amperes. The relative heating effect will be 9 2 as compared with 10 2, or as 81 is to 100. It is readily seen that, if the motor is designed to dissipate heat only as rapidly as it is generated under normal full-load conditions, a drop in voltage requiring an increase in current to maintain power will result in an overheated motor. An increase in voltage is serious only because of its effect [...]

It used the upper parts (knives, carriage, bridge, posts, guards, and handle) of the No. 1, and the lower parts (table and gauges) of the No. 6. The final entry in Oliver’s line of trimmers was the big No. 10.

Vic Thole recalls that at Mangolds Foundry they would often see warped manhole covers being straightened out with 4lb hammers! Subsequent castings were produced by LM Gateley in East London. They used fine grained cast iron. To assist in the manufacture [...]

It is clear then that if all the air could be removed from the inside of a pipe which is closed at one end while the other end is submerged in water, that the pressure of the air on the outside would force water up in the pipe until the weight of water in the pipe exactly balances the air pressure on the surface of the water. If there is some air trapped above the water in the pipe, the water will rise only to such a height as is necessary [...]
