LITTLE LOCOMOTIVES.
FINE MODEL MACHINES COSTING
HUNDREDS or DOLLARS.

Pretty Fine Toy Engine-Some of Then
work and Some by Electricity on Il
Third-RaiI system--Toy RAILROAD
Equipment i'm Great Variety.
Modern locomotives complete, o.
parts with which such locomotives
may be built, are nowadays sold II
such numbers that the production con
Stitutes a branch of manufacture by
itself. The locomotives are made il
four standard sizes, of which the three
smaller are those more commonly sold
The largest of all is as likely to be sole
for business uses as for the purposes OF
a model.
No. /, the smallest of them, has a
length over all, engine and tank, oil
thirty-nine inches, runs on track OF
three and a half inches gauge, and is
of three-eighths of horse power. 1t is
sold for one hundred dollars. No is
of half horse power and hfty-elght
inches over all, runs on track of i've
and quarter inches gauge, and sells
1 for one hundred and fifty dollars. No.
3 is of one horse power, and seventy
EIGHT inches over all, runs on a seven
inch track and sells for two hundred
and fifty dollars. No, 4, Of two and a
half horse power, is one hundred and
eight inches in length over all, runs on
a track of twelve inches gauge, and is
sold for five hundred dollars
These are all copies of a heavy pas
senger locomotive of modern type, and
made to scale. They are complete
working locomotives in miniature.
/ There is also made model locomotive
/ engine of the type used on the eleva-
ted railroad in this city. 1t is twenty
six inches in length over all and sells
for fifty dollars.
The model locomotive, handsomely
nickel-plated, is sometimes sold to be
placed in the office of some railroad
company Inventors buy these locomo-
tives upon which to display to the best
advantage new and improved appli-
ances: and, sometimes, for the better IL
Illustration of improvements in track
equipments, as in frogs and switches,
the model locomotive Is shown in mo-
ton Technical schools buy them to IL
lustrate the valve motions. Youths
about to take up the study of me"han-
ical engineering buy them, as do young
men already engaged in such study or
Just graduated from it, as a practical
aid in their pursuit of knowledge Of the
mechanisms involved. Such engines
are sold to be given away, as for in
stance by some generous giver to boy
or young man who was interested in To-
comotives Such an engine as the No.
8 has been put to actual use In the OPP
Grafton of a railroad In back yard
and hauls little cars carrying children.
In large room in house, here in the
city, there has been put down minia-
ture railroad system, tracks and
switches and so on, upon which mod
ell locomotive is operated; In this case,
however, not for amusement but for
purposes Of experiment and observa-
ton; this installation having been
made, as all changes in it from time to
time are, by the experimental.
But while the number of model loco
motives sold complete is considerable,
there are sold more parts from which
like locomotives may be constructed,
These parts are sold in the rough, to be
worked up and finished by the person
who thus devotes himself to the build
ing of a locomotive. They are fur
nished for all the different sizes of en-
gines. The cost of any set of parts Is
of course very much less than that Of
the finished engine. The total number
of parts supplied in a set for the engine
of the smallest size is upward Of one
hundred and fifty, including such
things as cylinders and pistons. slide
valves and valse stems, knuckle joints
and rocker boxes, links and link lifters
tumblng shaft and reverse lever truck
frame and center bearing, and eccen-
tries connecting rods, side rods, head
light, smokestack, bell, sand box, and
so on The diameter of this engines
cylinders Is three -fourths of an inch,
stroke Of cylinders one and three
eighth inches. The diameter of the |
driving wheels is four and one-fourth |
inches, and of the truck wheels one and |
inches. Length of boilers
seventeen inches diameter three and |
three-e eighth inches; height of stack |
above rails nine and five-eigth inches. |
The castings for various parts of |
these engines, such as cylinders steam |
chests, main frames, tall piece and |
wheels, are supplied in brass, in iron,
and in aluminium alloy, as may be pre-
ferred; the other parts being of brass
Or iron or of steel. For the use to
which it Is here put the aluminium al
oy is well adapted on account of its
Iightness the ease with which it can
be worked in lathe or palmer, and it's
hardness and beauty of finish. Driving
wheels of this material, for example,
night be painted as locomotive wheels
would be, with their rims left implanted
% stand for the steel tires.
Not everybody has the tools and the
machines that would be required to
inish all the several parts of the en-
zine, and people often, this of course,
adding something to their cost, get
more or less of the parts in a finished
tate, SC that the fitting remaining to
,e done shall be such as can be done
With comparatively few and simple
ools. Most people buy the boiler COM
,lete, many get the cylinders bored, the
'iston rod fitted to cylinder and so on
'ome buy many parts finished and
ONE have one thing finished and some
mother. And some take all the parts
