Capstan "The capstan is a familiar example of this form of wheel and axle. It is used by sailors for warping vessels up to a dock, raising anchors, &c.; and consists of a massive piece of timber, round which ... |
 |
Gear train "A combination of wheels and axles, as shown, is called a train. The wheel in a train to which motion is imparted from a wheel on another shaft by such means as a belt or gearing, is called the driven... |
 |
Rope machine "The large wheel a, is supposed to stand over the well, and b, a smaller wheel, is fixed in the water. The rope is extended between the two wheels, and rises on one side in a perpendicular disrection.... |
 |
Savart wheel "The Savart wheel consists of a heavy metal toothed wheel that may be put in rapid revolution by pulling a cord wound upon its axis. Set such a wheel in rapid motion and hold the edge of a card again... |
 |
Spinning Jenny "This machine carried a number of spindles turned by cords or belts from the same wheel, and operated by hand. It was a very simple affair, but it spun at first eight threads then sixteen, and within... |
 |
Spinning Machine, Arkwright's A spinning machine which produced a stronger thread than the spinning jenny. ... |
 |
Spinning Mule A spinning machine invented by Samuel Crompton. It spins textile fibers into yarn by an intermittent process. ... |
 |
Spinning Wheel "A band or cord (E) connected the large wheel with the small wheel (D). Another cord (F) connected the small wheel with the grooved pulley, or wharve, on the spindle (C). The revolutions of the large ... |
 |
Spinning Wheel An early spinning wheel.... |
 |
System of Wheels "System of Wheels.—As the wheel and axle is only a modification of the simple lever, so a system of wheels acting on each other, and transmitting the power to the resistance, is only another for... |
 |
Vertical wheel and axle "[This illustration] shows a third form of the wheel and axle. Here the axle A is vertical, instead of horizontal. A bar inserted in its head, at the extremity of which the hand is applied, takes the ... |
 |
Wheel A wheel is a circular device that is capable of rotating on its axis, facilitating movement or transportation.... |
 |
Wheel and axle "The wheel and axle consists of a wheel united to a cylinder in such a way that they may turn together on a common axis. It is a modified lever of the first or second class." — Avery, 1895... |
 |
Wheel and Axle "The wheel and axle consists of two cylinders of different diameters, rigidly connected, so that they turn together about a common axis." — Hallock, 1905... |
 |
Wheel and axle "It consists of two wheels, one of which is larger than the other, but the small one passes through the larger, and hence both have a common centre, on which they turn." -Comstock 1850... |
 |
Wheel and axle "This figure represents the machine endwise, so as to show in what manner the lever operates. The two weights hanging in opposition to each other, the one on the wheel at a, and the other on the axle ... |
 |
Wheel and axle "To change the direction, it is only necessary that the rope by which the weight is to be raised, should be carried in a line perpendicular to the axis of the machine, sto the place below where the we... |
 |
Wheel and axle "The wheel and axle consists of a wheel united to a cylinder in such a way that they may turn together on a common axis. It is a modified lever of the first or second class." -Avery 1895... |
 |
Wheel and axle "Considered as a lever, the fulcrum is at the common axis, while the arms of the lever are the radii of the wheel and of the axle. The usual arrangement is to take ac, the radius of the wheel, as the ... |
 |
Wheel and axle "...the mechanical advantage of this machine (wheel and axle) equal the ratio between the radii, diameters, or circumferences of the wheel and of the axle." -Avery 1895... |
 |
Wheel and axle "The wheel and axle is simply a revolving lever of the first kind. One application of the lever can not move a body any great distance; but, by means of the wheel and axle, the action of the lever is ... |
 |
Wheel and axle "Instead of having a rope attached to it, the wheel is often provided with projecting pins, as shown, to which the hand is directly applied." —Quackenbos 1859... |
 |
Wheel, Crown A wheel having cogs or teeth set at right angles with its plane. Commonly used in watches. ... |
 |
Winch "A still more common form, much used in drawing water from wells and loaded buckets from mines, is shown [here]. Instead of a wheel, we have here a winch, or handle, attached to the axle." —Quac... |
 |
Windlass A cylinder or roller for raising weights, turned by a crank or lever, with a rope or chain attached to the weight.... |
