[...] horse-power, double tandem compound engine, built by Messrs. McIntosh, Seymour & Co. , of Auburn, N. Y. The high pressure cylinders of this engine measure eighteen, and the low pressure cylinders, thirty-two inches in diameter, while the stroke amounts to three feet. A speed of 112 revolutions per minute is maintained. The sectional view, which is given of one of the pairs of cylinders, will help to give a better idea of some of the principal details of the design. Between the high and low pressure cylinders there is what [...]
[...] inches in diameter, and the exhaust pipe to the condenser measures ten inches. The steam ports in the high-pressure cylinders are seven-eighth inches, and the exhaust ports 1 7/16 inches wide, and both are sixteen inches long. The steam and exhaust ports of the low pressure cylinders are respectively 1 15/16 and two and a quarter inches wide and thirty inches long. The crank pins are 4 7/16 inches in diameter and five inches long. The tandem engine, of which an illustration is shown, is made from the old patterns. The cylinders are sixteen inches in [...]
[...] compressed in the engine cylinder to such a great pressure that the temperature resulting is sufficiently high to ignite the fuel automatically, as it is sprayed by an auxiliary pump into the engine cylinder. The compression pressures carried in engines working on the Diesel cycle are about 500 lb. per square inch, while those carried in engines working on the Otto cycle and with the same fuels are 55 to 90 lb. per square inch. Classification of Gas Engines Gas engines are divided into two classes, according to the number of piston strokes [...]
[...] greaser or a full bath oiler. Jointers are also a natural for this type of bearing and it works great.
High Speed Bearings Run-of-the-mill sealed bearing have contacting seals which generate heat due to friction. Some manufacturers such as Koyo make a non-contacting seal that will allow higher speed operation without as much heat buildup.
The problem gets worth considering when you are running in the 10-20,000 rpm range which for most of us means shapers.
In these higher speed ranges, the cage material becomes critical. Regular old motor bearings have steel cages. [...]

[...] compendious form of engine to plough ground without horses or oxen, to raise water from any low place to high places for well-watering cities, towns, and gentlemen's houses, and to make boats run upon the water as swift in calms and more safe in storms than boats full-sailed in great winds. In 1630, Ramsey took out another patent of nine claims, the second of which reads, "To raise water from lowe pittes by fire;" and this is considered the earliest notice of an engine for raising water by fire in England.

[...] under somewhat less favorable conditions. Certain types of loads require motors with high starting torque. A deep-well plunger pump is an example of this type of load. When the water column is high the motor must not only overcome its own inertia but that of the pump mechanism and the water as well. It must really start more than its full load. The same thing may be said of any positive-action pump but not of the centrifugal pump. The centrifugal pump assumes its full load as operating speed is approached. [...]
THE PORTER ENGINE Porter-Allen High Speed Engine
In 1862 Charles T. Porter exhibited at the International Exhibition, London, an 8 x 24-inch engine running at what seemed then a fearful speed, 150 revolutions per minute. This was afterward set up in London and ran 225 revolutions. While I was there and saw this engine in the exhibition of 1862, my mind was occupied in other directions, and I paid very little attention to it. I did, however, see Mr. Porter, and copied for him the drawings of the Richards indicator on parchment for his patent [...]
[...] current input, but the operating speed is subject to greater variation. They should be applied where high starting torque is desired and where moderate speed variations with change of load are not objectionable, or where starting is frequent. Series-wound d-c. motors develop higher starting and maximum torque than either the shunt or compound types, but while operating the speed varies considerably with the load, increasing as the load is decreased. Because of this fact they should be used only where they may be geared or directly connected to the load, [...]

[...] the air. A column of air one inch square extending from the surface of the earth, at sea level, as high as the air reaches, weighs 14.7 pounds. If we go up on a high mountain or up in a balloon, the air presses upon us with less weight because there is not so much above us. The weight of the air does not hinder us from moving because it is equal on all sides and hence all pressures are balanced. A column of water one inch square and one foot high weighs 0.434 pound; consequently it would require [...]
[...] made to the existing record. I had seen old Oliver catalogs and was amazed by the size, features, and quality of their products. One type of machine that especially intrigued me was the mysterious Universal Trimmer. The larger versions, with their capstan wheel operating mechanism, looked like something you’d find on board a sailing ship. I was presented with the opportunity to purchase one in 1999. The seller told me it was marked “American Machinery Works - New Haven, Conn.”. I was aware that Oliver had initially been known as the American Machinery Company. I also [...]

[...] is a softer, non-conductive material called "mica". In order to ensure clean contact between carbon brush surfaces and the copper bars, the top surface of the mica should be slightly recessed below the surface of the commutator bars. After turning the bars down, a user often needs to remove a small top layer of the mica to create that recess. This process is called undercutting the mica. Here is the commutator end of the rotor from a 1hp RI bullet motor. The carbon build-up on the copper surface is obvious, and it's also apparent that the commutator has been turned [...]

[...] sixty years. Owning and using so many of these machines has provided me with insight regarding the true quality of the machines—how they were made and, importantly, how easily they can be restored. This history of the Crescent Machine Company is my first real attempt to share the results of my research to date. I doubt that I will ever quit collecting information on Crescent and adding to my database, but I feel that the time is right to publish what I know and have learned.

[...] brass or babbitt boxes, runs with much less friction than in iron boxes however well made, and here the quality of the brass or babbitt becomes another important factor. To illustrate the great advancement made in reducing friction in engine building, the following is pertinent. A well-known authority says the internal friction of engines twenty years ago ran as high as fifteen or twenty per cent. On some recent tests of traction engines at the plant of one of the great thresher houses, the internal friction ran as low as [...]

[...] worried about doing this brazing job. The last time I brazed anything was back in my sophomore year of high school when I took a metals technology class. That was in 1982. I did a little reading to before hand to refresh my memory and just got in there and started brazing. It did not take long and it was all coming back to me. In the end, I got the three parts brazed back together and I thought that the brazing job was pretty good - epically since it has been 22 years since the last time! Picture below. 8 - Friday, October 8, 2004 Not much time today to do anything [...]

It is not suitable for belt stock. Figure 65 Single belting is made from a single thickness of skin. To make a long belt the strips of leather are glued together. Care is taken to make the belt perfectly straight. If it is only slightly crooked it will never run straight on the pulleys. Double belting consists of a double thickness of skin glued [...]
[...] parts of a steam engine are illustrated in Figs. 33 and 34. Steam from the boiler at high pressure enters the steam chest A , Fig. 33, and is admitted through the ports BB alternately to either end of the cylinder by the valve C . The same valve also releases and exhausts the steam used in pushing the piston D . E is the cylinder in which the steam is expanded. The motion of the piston D , Fig. 34, is transmitted through the piston rod F to the cross-head G , and through the connecting rod H to the crank I , which is keyed to the shaft [...]

ANS. Upon the matter of its " running" quality. Ques. What could be considered a fair "running" requirement in a new engine, in the hands of a first-class engineer?
ANS. A satisfactory running engine is one which has the stationary parts of such strength and security that there is absolutely no movement at any point due to the reciprocating of the moving pieces. In an engine which is perfectly satisfactory in this respect, a slender rod with a squared end, such as a common lead pencil, can be placed in a [...]

Babbitting High Speed Bearings taken from Machine Moulder Practice, by W. H. Rohr, 1919. Babbitting the boxes, which carry high-speed spindles, is very particular work and calls for the exercise of both skill and good judgment. On some machines there is a brass name-plate bearing the words, "Never babbitt on a cutterhead journal; you may spring it, and once sprung it cannot be permanently repaired ; use a babbitting mandrel." This is good advice and should always be followed when possible. The greatest danger in springing a journal is [...]
