Mills for Farm lise. 
Of late years many improvements have been made 
Fig. 1.—HARRISON’S STANDARD MILL. 
in mills for farm use, and a large variety of them 
have been constructed for different purposes, such 
as grinding flour and meal, feed for stock, bones 
for fertilizing, and other similar uses. More recent¬ 
ly, however, as manufacturers have learned precise¬ 
ly what their customers require, and the purchasers 
have learned to appreciate the conveniences offer¬ 
ed by the various mills, the increasing business has 
led the manufacturers to make still further im¬ 
provements, and to offer very complete machines 
at very reasonable prices. To meet the numerous 
enquiries which are continually made about mills 
for various purposes, we here describe and illustrate 
some of the most valuable of them. Iu figure 1 
we have a complete grain cleaning, grinding, and 
bolting mill, in one machine, with which the whole 
process may be brought within a very small com¬ 
pass, and completed upon a barn floor, if needed, 
with no more power than can be furnished by the 
farm teams or steam engine, or which may be set 
up in a couutry mill with the greatest economy of 
space, power and yield. For instance, the machine 
illustrated in fig. 1 has a pair of burr-stones of 20 inch¬ 
es diameter, weighs 1,200 lbs., takes up a space of 
only 4x9feet, or 36 square feet, requires 3 to 6 horse¬ 
power, makes 500 to 700 revolutions per minute, 
grinds 3 to 7 bushels per hour, according to the 
power employed, and costs at the factory $450. Un¬ 
cleaned grain, direct from the thrashing machine, 
may be used with this mill, and the work is so 
as to separate the Dour into different grades. The 
cold air blast carries off all the vapor and damp¬ 
ness which arises during the grinding, and prevents 
clogging or pasting 
of the bolting cloth. 
The ordinary eleva¬ 
tors or spouts used 
iu a grist-mill may 
be applied to this 
machine, or the sim¬ 
ple flour chest as 
shown may be used. 
This mill, which is 
known as “Har¬ 
rison’s Standard 
Mill,” is made by- 
Edward Harrison, of 
New Haven, Conn. 
A mill that can be 
used for grinding 
every thing that is 
ever ground at all, 
corn, corn ears, 
bones, horns, hoofs, 
plaster, shells, paint, 
ores of different 
kinds, fertilizers, sumach, and any material, whether 
hard or soft, is shown at figure 2. This is known as

simple that any person of ordinary common sense 
may, after a little practice, set up and work the

mill with success. The grain having been put into 
the hopper, which holds 2 bushels, or an ordinary 
bagful, passes into the cleaner J, and is scoured 
and freed from all dust. From the cleaner it goes 
to the stones and is ground. As the meal leaves 
the stones it is thrown, by a strong blast of cold 
air, from the double door A, through a wire screen 
against the bolt cloth, O, (covered by the door Q), 
by which it is separated into fine flour, (at F,) mid¬ 
dlings, (at M), and bran, (at B). At J is an adjust¬ 
able feeder, which regulates the supply of grain to 
the stones. The bolt is made of the usual silk 
bolting cloth, of different degrees of fineness, so 
the “Bogardus Eccentric Mill” and is made by John 
W. Thomson, corner White and Elm streets, New 
York City. The complete mill is shown at figure 2 ; 
a section of the mill at figure 3, and the grinding 
plates at figure 4. The peculiarity of the mill con¬ 
sists in the plates. These are made with a number 
of cutting edges, and as they revolve on centers 
differently placed, the cutting edges cross each 
other and form the most powerful and effective 
grinding machine that we know of. For grinding 
bones for use as fertilizers, corn, corn ears, or 
whole corn fodder with ears in the husk for fodder, 
for grinding plaster, and other similar uses, this 
mill is of very great value to farmers, or country 
millers, who by running one of these mills could 
serve their customers in grinding plaster, bones, 
horns, hoofs, shells, oil-cakes, and other such ar¬ 
ticles^ service which is frequently required of them. 
At figure 5, is the Farm Feed-mill of Wm. L. Boy¬ 
er &Co., of Philadelphia, a very convenient mill to 
be run by a two-horse tread-power. This mill is

called the “Premium Farm Grist-Mill.” The 
grinding parts are of cast-steel. It was tested at 
the Centennial Exposition, and we are informed 
that it received an award for superiority. 
A mill for a similar purpose, shown at figure 
6, is made by the Bradford Mill Company of Cincin¬

nati, Ohio. This mill is intended to grind corn, 
feed, plaster, cement, and spices. It is under-run¬ 
ning, very strong and compact, and quite portable. 
At figure 7 is a mill made by the Straub Mill 
Company, also of Cincinnati, intended for grinding 
corn and stock feed by the ordinary horse-power, 
such as most farmers have, or by steam. 
In addition to these there are several others 
which are equally serviceable, such as the “Conical 
French Burr Mill” of L. 
J. Miller, of Cincinnati, 
made for grinding wheat, 
com, and feed; the mills 
made by the Blymyer Man¬ 
ufacturing Co., of Cin¬ 
cinnati, which seems to 
be the headquarters for 
this class of machinery 
and others, the particular ^ st AAUB mill. 
locality of whose place of manufacture will make 
them conveniently reached by intending purchasers. 
From our own experience with portable mills we 
are satisfied that a very great saving in feed may be 
effected by their use. In our own experience our 
feed-mill paid for its entire cost the first year. 
A New Double Carriage Spring. 
Some time ago, when being driven over a road so 
rough as to be impassible to an ordinary vehicle, 
we noticed that the carriage passed over the ob¬ 
structions in a remarkably easy manner, without any 
damage to the springs. We were led to inquire iuto 
the character of the springs and the mode in which 
they supported the body of the carriage, and found 
that they were known as the “Dexter Springs.” 
Few if any other springs could have endured the 
test to which these were so successfully submitted. 
Their construction, which is peculiar, may be under¬ 
stood by reference to the accompanying engraving. 
They are seen to be double, and braced in the centers 
in such a way as to throw any strain upon each one' 
equally and at the same moment. This giyes 
strength and durability to them. Their form is very 
graceful, and adds beauty to the vehicle; theit
