many Hall, New York, in 1835, when the radical faction, 
after their opponents had turned off the gas, relighted the 
room with candles by the aid of locofoco matches. The Loco- 
foco faction soon disappeared, but the name was long used

locomotion (lo-ko-mo'shon), n. [= F. locomo- 
tion = Sp. locoiitocion = Pg. locomo^ao = It. 
locomozione, < L. locus, a place, + motio(n-), a

from place to place ; progressive motion, as of 
a living being or a vehicle; the act of moving 
from point to point; also, the capability of 
moving in this manner. 
A clock, a mill, a lathe moves ; but, as no change of the 
place of the machine Is produced, such motion is not lo- 
comotion. Brand and Cox. 
Every act of locomotion implies the expenditure of cer- 
tain internal mechanical forces, adapted in amounts and 
directions to balance or out-balance certain external ones.

dally strain, applied to the transport of loads on land. See 
railway. Locomotive pupa. See pupa. 
II. H. A steam-engine which travels on 
wheels turned by its own power; specifically, 
an engine designed and adapted to travel on a 
railway; a railroad-engine. Locomotives designed 
to travel upon the ground or ordinary highways and to 
draw loads are more commonly called traction-engine! ; 
and those used upon common roads and designed to carry 
passengers are called steam-wayonn or tteam-carriagt*. 
(See traction-enyint and gleam-carriage.) American loco- 
motives are distinguished from those constructed in 
other countries by the exterior position of the cylinders, 
the absence of heavy framing, the use of bogies, a system 
ot suspension by means of bars or levers, and certain 
minor features, such as the cow-catcher and single head- 
light. The essential parts of a locomotive are the boiler 
(usually long, horizontal, and of the " locomotive type 
(see locomotive-boiler), with many tubes), the running-gear 
or wheel-system, ana the engine proper, this being a dou- 
ble-cylinder, reversing, high-pressure motor, of which the 
exhaust-steam is thrown Into the smoke-stack to urge the 
draft of the fire. The various wheel-systems employed 
have given rise to special types of locomotives. See 
passenger-locomotive, twitching -locomotive, tank -locomotive, 
etc., below. See also cut under paNtfnger-cngine. Back- 
truck locomotive, a locomotive having a truck with a 
pair of wheels under its rear end, as well as a truck in 
front of the driving-wheels. 8uch locomotives are used 
for sharp curves and steep grades. Belgian-tank lo- 
comotive, a locomotive having a tank on each side of the 
boiler. Compound locomotive, a form of locomotive In 
which is embodied the principle of the compound steam- 
engine. Compressed-air locomotive, a locomotive 
which is driven by compressed air carried in strong tanks 
filled by compressors at stations. In some compressed-air 
locomotives the air is heated on its way to the cylinders, 
either by the direct application of heat or by the Injection 
of steam. Such locomotives have not come into practical 
use. Consolidation locomotive. See consolidation. 
Double-ender locomotive, a locomotive which has 
the rear of the tender provided with a pilot, or cow-catcher, 
so that It may be run with either end in front. It has a 
two-wheel truck in front of the driving-wheels, the latter 
being usually two in number. Double-piston locomo- 
tive, a locomotive each cylinder of which has two pistons 
with rods projecting from each end, and working on crank- 
pins set at 180 degrees from each other. Steam is admit- 
ted alternately to and exhausted from the space between 
the pistons and the spaces between the pistons and the 
cylinder-heads. The transmission of power from the pis- 
ton-rods to the crank-pins is through cross-heads and con- 
necting-rods, and, as the crank-pins are always moving and 
receiving their increments of power in opposite directions, 
a balancing of strains results. An attempt has been made 
to remove In this way some of the Internal disturbing 
forces of the locomotive. The practical difficulties of the 
system have, however, been fatal to its extensive adoption. 
Also called double-cylinder locomotive. Double-truck 
tank-locomotive, a locomot lie which has two trucks, and 
carries boiler and tender on a single frame. The cylinders 
are attached to the truck that carries the boiler, the wheels 
of this truck being the driving-wheels. The other truck 
supports the tender. A common form has six coupled driv- 
ing-wheels on the forward truck, and a six-wheeled truck 
at the rear under the tank. Called in the United States 
Mason's locomotive. Flreless locomotive, a locomotive 
driven by steam generated from highly heated water car- 
ried in strongly constructed tanks. From such water, 
on a reduction of pressure upon it, saturated steam will 
be generated under the law of related pressure and tem- 
perature of saturated steam. The supply of heated water 
is provided and pumped into the tanks at stations, and the 
tanks are protected from rapid loss of heat by heat Insu- 
lating material. Four-cylinder locomotive, a locomo- 
tive with four cylinders ana two systems of driving-wheels. 
The four-cylinder locomotive known as Fairlie's has two 
boilers with a double fire-box between them, the two parts 
of the fire-box being separated by a water-leg, and the 
whole being carried on two center-pin trucks. Meyer's 
four-cylinder locomotive has a single boiler and fire-box, 
and the cylinders are located near the middle of the holler. 
Freight-locomotive, a locomotive for drawing freight- 
trains. Great tractive power at the sacrifice of speed is 
attained in freight-locomotives, through their adhesive 
weight, large cylinders, and driving-wheels small as com- 
pared with the driving-wheels of passenger-locomotives. 
Geared locomotive, a locomotive In which the mo- 
tion of the engine is conveyed by gearing to the traveling- 
wheels, as in many traction-engines and road-rollers. (B. 
H. Knight.) Geared locomotives having toothed driving- 
wheels, the teeth of which engage a rack, are used for steep 
grades in mountain railways. Mine-locomotive, a loco- 
motive for use in mines, and peculiarly constructed to 
adapt it to run successfully on slippery tracks. With great 
adhesive weight, it has also all its wheels coupled. Mo- 
gul locomotive, a type of freight engine with three 
coupled driving-wheels on each side, and a swinging 
two-wheeled truck in front. The front pair of drivers 
are made without a flange, to facilitate the passing of 
curves of short radius. Passenger-locomotive, a loco- 
motive for drawing passenger-cars. Speed is sought at the 
sacrifice of power in passenger-locomotives, the peculiar 
characteristics of which are large driving-wheels and en- 
gines having short strokes In comparison with the diame- 
ters of tin ir pistmis Saddle-tank locomotive, a loco- 
motive which has its tank placed upon and externling 
downward over the sides of the boiler, after the manner 
nf a saddle. Street-locomotive, a locomotive adapted 
to use in public streets. It has a short wheel-base, power- 
ful brakes, and mechanism for muffling the exhaust so as
