R87458, 14Dec51, The Singer Manufacturing Co. (PWH) Instructions for using Singer sewing machines 108W20 and 108W21 cylinder bed, by Archibald Tregaskis.

Its construction is such as to require the best grade of cylinder oil, and without this it is very unsatisfactory, (not because the valves of other valve-motions will do with a poorer grade of oil) but because its construction is such that as soon as the valve becomes dry it causes the link to jump and pound, and very soon requires repairing.

A rapid deflection increases the amount of the deflection as well as the amount of the strain, as is seen in the cylinder cover of a Cornish pumping engine, into which the steam is suddenly admitted, and in which the momentum of the particles of the metal put into motion increases the deflection to an extent such as the mere pressure of the steam could not produce. 74.

A four-cylinder motor is practically putting forth power continuously, since one of the four pistons is always at work.

In some cases a double cylinder engine is used, in which the steam, after having given motion to a small piston on the principle of a high pressure engine, passes into a larger cylinder, where it operates on the principle of a condensing engine; but there is no superior effect gained by the use of two cylinders, and there is greater complexity in the apparatus.

"The cylinder-heads were almost opposite a high rock at the turns.

In the Munsey historical tour of 1910 a Brush single-cylinder car covered the 1,550 miles of a schedule designed for big cars and came through with a perfect score.

The grate area is 20.65 square feet, and the tractive power per pound of mean cylinder pressure is 111 lb.

33, which consists of a brass or iron box set over the two ports or openings into the cylinder, and a central port which conducts away the steam to the atmosphere or condenser; but the length of the box is so adjusted that it can only cover one of the cylinder ports and the central or eduction port at the same time.

The sum of all improvements in this department of mechanical invention is seen in the great cylinder-presses now in general use, especially the one known as the web perfecting press.

Chip the cylinder bottom fair; set it in its place, plumb the cylinder very carefully with a straight edge and silk thread, and scribe it so as to bring the cylinder mouth to the right height, then chip the sole plate to suit that height.

Holding strongly that single engines are more economical not only in running, but in repairs, and that cylinder power is generally inadequate to the adhesion, he has designed his magnificent well-known class of express engines.

The projection of the outer face of the trunnion flange from the side of the cylinder is 6-1/2 inches; the thickness of the flange round the mouth of the cylinder is 3/4 of an inch, and its projection 1-3/8 inch; the height of the cylinder stuffing box above the cylinder cover is 4-1/8 inches, and its external diameter 4-3/8 inchesthe diameter of the piston rod being 2-1/8 inches.

Inside cylinder locomotives.

If you thoroughly understand the working of the steam, you can readily detect any defect in your cylinder or steam chest, by the use of your cylinder cocks.

They immediately put in order an old squirrel cage with a little green house and a wire-cylinder wheel.

Hawthorn, in 1843, employed as an expansion valve a species of frame lying on the ordinary cylinder face upon the outside of the valve, and working up against the steam side of the valve at each end so as to cut off the steam.

Six cylinder love.

It was exactly 12:00 o'clock, and I was in the middle of the sentence, "How beautiful these bells chime," when a boy motioned me to come quickly to a certain place where I could see the cylinder revolve which communicates with the peal of bells.

If the steam is seen to blow out of the port at open end of cylinder, then the trouble is in the valve, but if not, you will see it blowing through from forward end of cylinder, and the trouble is in the cylinder rings.

In a car shaped like a motor-boat and as low to the ground Mr. Charley Cox turned in and with a great throttling and choking of engine drew up among the dim-eyed monsters of the grove and directly alongside an eight-cylinder roadster with a snout like a greyhound.

A.In well formed bolts, the spiral groove penetrates about one twelfth of the diameter of the cylinder round which it winds, so that the diameter of the solid cylinder which remains is five sixths of the diameter over the thread.

It is not an uncommon thing for an engineer (I don't like to call him an engineer either) to fill his sight feed lubricator with ordinary engine oil, and then wonder why his cylinder squeaks.

If you are carrying 90 pounds of steam you have about 320 degrees of heat in your cylinder, with I20 to I25 pounds you will have about 350 degrees of heat, and in order to lubricate your valve and valve-seat, and also the cylinder surface, you must use an oil, that will not only stand this heat but considerable more so that it will have some staying qualities.

The steam-cylinders act on the boiler a good deal as a lung-tester acts on a human being; the cylinders draw out the steam from the boiler, requiring a roaring fire to make the vapour rapidly enough and keep up the pressure.
