A Practical Traction Engine,
(Written for the Press.)
The subject of transportation by means of
the road-locomotive, or traction-engine as it is
called, has occupied the attention of engineers
in all parts of the world. lt is believed that
California has produced a machine that stands
among the best forms of the road-locomotive ;
from late tests it appears to be one of the most
practicable engines of this class that has ever
been introduced.
The accompanying engraving represents one
of these machines, on three wheels, all of which
are propelled hy beveled gearing.
The following are the principal dimensions :
Boiler—length over all, 10 feet; boiler, diameter of shell, 48 inches; hoiler, thickness of
shell, } inch; boiler, fire box sheets, § inch;
load on driving wheels, 2,300 pounds; steain
cylinders, diameter, 8 inches; stroke of pistons, 12 iuches; revolutions of crank to one
of driving wheels, 10; driving
wheels, diameter 72 inches;
driving wheels, breadth of tire,
12 inches.
The boiler is a new and peeuliar miultitubular arrangement, which makes steam as
fast as required, from a comparatively small amonnt of
water, doing away with considerable bulk and weight.
There are two engines mounted
ou top of the boiler; the crankshafts are coupled and the
cranks are set quartering to
avoid the possibility of ever
stopping on tho center; the
bed plates have the cross-head
guides cast solid with the bed;
and the cylinders are secured.
in sliding hearings fastened by
flanges to boiler-bracketa; hy
this means the expansion and
coutraction of the hoiler is acecommodated, avoiding a considerable strain on the engines. The driving-gears or
angle-shafts, are on each side
of the machine as shown, and
are driven by the beveled
pinions on each end of the
engine shaft. The angle-shafts
ruu in angle hracket-boxes, so
that one pair of shafts having
beveled pinions run the forward wheel-gears, andthe other
pair of angle-shafts also have
heveled pinions that drive
beveled wheels sccured’ to the rear traction
wheels, The forward driving gears are keyed
to the outer ends of the forward axle, or
driving shaft, more properly speaking,
as the latter drives the forward or steering
wheel, but at the same time allowing it to be
moved in au are of a circle sideways at any
angle desired for steering the machines. This
is accomplished by means of a ball and socket
joint in tbe huhof this wheel.
This ball and socket joint is the most ingenious part of the whole machine, and to accom. .
plish the work of driving the wheel in all positions, a numher of steel keys are fitted in the
Hi
ball, aud projecting to work in slots cut in the. ing 35 tons at a speed of three miles per
shell or casing of the ball,
__ This casing has projecting faces with revolying rings on each side of the wheel, and to
these rings are bolted arms on each side running back toa gear segment, operated by a
pinion on the end of an upright spindle or shaft
with a hand-wheel at the top, just in front of
the steersinan’s seat; here the man piloting the
machine has control of the throttle valve and
reverse lever.
This is the firstinstance in which the steering
wheel has been made to propel tbe machine;
and it can be made to do the work independent
of the bind wheels, in case of necessity; as for
instance when both hind wheels become mired,
or get into quicksand, or deep ruts in the road.
This is accomplished by haying self-adjustable
clutches on the hind wheel shaft, also for backing ete.
all of the traction engines heretofore built,
only two wheels have been employed to propel
the macbine, but in this invention all of the
wheels on which it rung are traction wheels,
and more than three may be employed if desired. This machiue was used for a consider.
able length of time in the State of Nevada,
hauling ore and other freight from mines to
mills, etc., running np mountainous roads
(where mule teama had Seat used); the grade
being in some instances 530 feet to the mile,
and hauling ten tons on wagons ata speed of
two and one-half miles per hour. After working for one company until their mines gave out,
the machine was brought to Sacramento, where
it was employed in house moving and other
heavy work.
The Sacramento Wood Co. have recently
bonght a Pacific coast interest in this invention,
and have put the machine to a very severe
test, showing its ability to haul heavy freight
in a successful manner. Capt. J. Roberts, the
leading spirit of the company, took this machine up the Sacramento river on one of their
steamers, and landing in Colusa county, where
clusions: A traction engine, or road locomotive,
may be constructed upon this plan, so as to be
easily and rapidly manceuvred, hauling a long
line of freight wagons on the ordinary roads,
and turning without difficulty on a circle suoh
as are common at all cross-roads,
A locomotive weighing six tons is capabic of
haubng 25,000 pounds up a grade of 525 feet to
the mile at a speed of 34 miles an hour. The
traction-power of the machine tested was eqnal
to 30 horses.
The coeflicient of traction was shown to be
about 0.5; the weight that could be drawn on
a perfectly smooth and level road was 175,000
pounds; this is exclusive of the weight of the
engine, and the amount of fuel required is estimated at 500 pounds afday. In handling the
machine the most experienced and skillful men
are required. The difference between the performances of the same engine in different hands
was 127.
It is estimated that the expense in heavy
hauling hy steam is 25% less than the cost of
horse-power on an ordinary road. A much
The Bodie Claims,
The Bodie mines were taken up under United
States law, and held as from the United States,
But now it transpires that tho United States
did not own the land occupied by many of the
chief mines; on the contrary, the State ownedthem, and the United States conld not allow
any one to hold them either by yearly work or
by purchase—in fact, bad no claim on them
whatever. The State owns the 16th and 36th
sections of every township, She was granted
them for school purposes, Owning them she
has a right to sell them, This she has done ia
the preseut case, and there was no stay in her
proceedings, because the 16th section of one
township contained some of Bodie’s richest
mines. The plat of survey of the land in question was filed on March 16th, 1878. At that
time those who were located on the 16th secthey run regular trips back into the country, 2! larger and more powerful machine is now being . tion might have known how they were situated,

distance of 16 miles, taking freight from the
steamer, and bringiug wheat hack, they loaded
six Bain header wagons with 300 sacks of grain,
also hauling one extra Bain beader wagon contaiuing a tank in which they took 615 gallons
of water, besides 14 tons of coal, making over
24 tons total freight in wagons; tbe machine
also carried tanks secured at each side of the
hoiler, these bolding 250 gallons of water.
Five miles of the road was very dusty, and full
of ruts, we had several sloughs to cross, making
a very severe test of the traction power of the
machine. But if the roads are level, hard and
free from ruts, the machine is capable of haulhour.
The machine works admirably as to pulling
or traction qualities. The machine weighed
on the scales—haying steam up and 250 gallous
af water in the tanks, also coal in the cab—114
tuna total weight.
Capt. Roberts’ Company has plenty of work
for a large number of these machines, as they
haul freight from various points throughout the
Sacramento and San Joaquin valleys to their
steamboats and harges on the rivers.
This traction engine will run over any kind
of ground; it can enter any farmer’s field, plow
his ground, and at the proper time haul away
his grain or other freight, running in any direc.
tion without reference to depots or tracks that!
at present are so necessary for tbe transporta-.
tion business of the country. /
From the recent trial of this engine, the constructing engineer deduced the following con-.
built for the company by Root, Neilsou & Co.,
Sacrameuto. The inventor is Mr. R. R. Doan,
who commenced many years ago to study the
problem of substituting steam power for auimal
power on the highways and for farm use.
After years of toil and the expenditure of a
large amount of moncy, buildiug the machine
in several styles, he has profited by the experience, and we believe that he has accomplished
the desired result, in the road locomotive
represented by our engraving. Cc. W. M
Bosweit Fruit Drrer.—We call attention
to the advertisement of the Boswell heater!
oompany on page 16 of this issue. The principle of deflected heat as applied to drying fruit
seems to he worthy the attention of all interestedin that branch of industry. The combined ‘apparatus for cooking, baking, beating,
drying, etc., is a great auxilliary to the econ.
omy of housekeeping, and the apparatus is also
claimed to he the most economical as well as
the hest arrangement for drying fruit, etc.,
that is now before the public. Mr. E. L. Sullivan, an old and well-known citizen of the State,
is at the head of the company.
Tue Salt River Herald says: Messrs. I. N.
Cohen & Co. have received 30,000 pounds of
copper from the Longfellow oompany during the
past week; shipping 20,000 to the railroad dnring the same time.
Work progresses favorably at the Black
Jack, Idaho.
From that date they were allowed the refnsal of the land
for six months. Those six
months have passed. The locators bave not purchased from
the State. Others have taken
advantage of this negligence,
and bave bought the land and
hold a State title to it. The
title seems to be good, and all
that Bodie can do is to compromise. The interested mines

Bodie stock has been surprisingly low for some weeks
past. It has exhihited a
deaduess which grew, perhaps, out of some premonition,
if not positive knowledge, of this trouble. It
will be a great pity if this flourishing town is
to receive 2 set: back here ou the very threshold
of so promising a career. Mining towns in the
first few years of their growth are particularly
liahle to such disorders, “But perhaps none
other ever received such an aggravating blow
as this that has been dealt Bodie.
