DIAGRAM OF THE BUFFALO PITTS 
THRESHER. 
The accompanying diagram of the Buffalo 
Pitta Thresher, made 
by Pitts Agl. Works at 
Buffalo, N. Y., will 
give a clear idea of 
the mechanism of 
this well-known ma¬ 
chine, and its mode 
of operation. 
A is the feed-board 
on which the grain 
is spread and passed 
to the cylinder, R. B 
is the threshing cylin¬ 
der with iron spikes 
or teeth a, fixed at 
certain distances from 
each other through¬ 
out its length and cir¬ 
cumference. C is the 
concave, also having 
iron spikes or teeth a 
set in it. 
The concave is 
fixed ; the cylinder re¬ 
volves rapidly on its 
shaft. As the graiu 
is fed into the cylin- -- 
der, the cylinder teeth 
catch it and drag it 
at great speed between the rows of concave 
teeth,—literally combing the graiu out of the 
straw. 
J) is the grain belt,—an endless belt of stout 
duck on which are nailed wooden buckets or 
cells b. This grain belt rnns on the rolls, c, and 
over tbe pulleys, d d, and receives from the 
cylinder tbe straw and threshed grain and car¬ 
ries it away,—the straw ridiDg on top and the 
grain di opping into the cells. 
Tbe rol's, c are hexagonal (not circular as er¬ 
roneously shown in drawiug) and thus constantly 
agitate tbe belt and promote the separation of 
grain from the straw. 
F. is the beater—four wings, with iron fingers 
e, revolving on a shaft. These wmgs constantly 
beat the straw as it passes under them and thus 
further assist to dislodge any loose grain from 
the straw. F is the picker. 
G is the straw belt — an endless belt— made 
of slats of wood nailed, at short distances from 
each other, to two leather belts, farming an 
endless ladder. This belt runs over the pulleys 
ff- 
E is tbe agitator—a bar rooking on its cen¬ 
ter—so that tbe ends h h alternately strike tbe 
belt and shake the straw 7 is a tight floor. K is 
a wire riddle (or siev ) in the shoe. N size of 
mesh vanes according to the kind of grain to be 
threshed. M is an opening for discharge of straw. 
As Die grain belt I) tnrns over the pulley d, 
the threshed grain 
drops ont of tbe 
cells b on to tbe 
ridd'e E. At the 
same time the pick¬ 
er F tosses the 
straw over to the 
straw belt <?, and 
by this tbe straw 
is carried to the 
aperture M, and 
discharged. 
Tbe ends h of 
the agitator 77 
striking the straw 
belt c a u s e any 
grain still lodged 
in tbe straw to 
drop between tbe 
slats on the floor 7. 
and by tbe re turn- 
ing (linger) Side of 
the lelt this g-nin 
is swept on to tbe 
riddle E 
E is tbe shoe, 
having longitudi 
nal motion. O is 
an eccentric, giv 
ing motion to the 
shoe P is tbe fan. 
(j is the drum en¬ 
closing it. It is a 
fine sieve forming 
part of the bottom 
of the shoe. S is 
the grain conveyor 
—a screw working 
in a trough. T is 
the tailings oon- 
veyor—similar to graiu conveyor. V boards 
guiding the grain in its fall on to the sieve E. 
W, concave raiser to regulate distance between 
cylinder and concave. As the grain falls from 
the grain belt cells b, and from the floors I, 
toward the siove, K, the blast from the fan, P, 
blows the chaff over the end of the shoe, AT. 
The grain is sifted through the riddle K on 
to the shoo floor (which is sharply inclined) and 
rolls into tbe conveyer /? by which it is delivered 
to the receptacle at side of machine-perfectly 
clean. 
Any fine seeds which pass through the riddle 
K with the grain, fall through the fine screen R 
into the box beneath. 
Whatever falls on tbe riddle and does not sift 
through it is, by the longitudinal motion of the 
features. The facilities of this Company for pro¬ 
ducing high-class work are ample, and embrace 
not only the farm engines under notice, but sta¬ 
tionary and portable engines of most of tbe ap¬ 
proved designs, including the Corliss model. In 
the material used throughout the work considera¬ 
tions of price are subordinated to quality. The 
castiugs arc made of charcoal iron, and the minor 
parts, such as pumps, governors and safety- 
valves (of which there are two on each of the 
engines illustrated), spark-arresters, safety-

AMERICAN FARM ENGINES. 
The use of steam engines for farm purposes 
is of quite recent date in the United States, but 
THE ‘'BOSS CLIPPER” VERTICAL ENGINE 
so rapidly are they growing in favor that a num¬ 
ber of large manufacturing concerns find this 
Bpeoial industry a lucrative business. The com¬ 
petition has led to ceaseless efforts in the pro¬ 
plugs, etc., are finished thoroughly, and com¬ 
bine some of the latest improvements. 
The novel features of the horizontal engine 
are, the manner of staying the crown sheet, and 
the device for supplying dry steam to the cylin¬ 
der. Trusses of wrought angle iron exteudiug 
the whole width of the crown sheet, with the 
ends turned down and resting on the edges of 
the side Bbeeta of the fire box, and placed four 
inches apart the whole length, are additionally 
strengthened by two braces fastened from the 
outside shell of the boiler to each truss. The 
“throat,” or connecting sheet of the boiler, is 
also fastened by a double row of rivets. The 
stay holts in the sides of the lire box are close 
together, and washers placed between the trusses 
and the crown sheet, leave spice for the circu¬ 
lation of the water and prevent sediment col¬ 
lecting. 
The cylinder is worked inside the cast iron 
steam dome, and is constantly surrounded with 
steam of the same temperature as that, generated 
in the boiler. This arrangement obviates con¬ 
densation, and secures a strong, elastic force. 
This feature constitutes the dry steam patent. 
In the vertical engine, the flues of the boiler 
are always below the water line, and by the shape 
of the dome aud fire box, which are narrow at 
the top and wide at tbe base, a direct heating 
surface is attained. It is claimed that this ar¬ 
rangement prevents the flues from being injured 
ated more rapidly, and that the flues can he 
quickly repaired at will without damage to fire 
box or boiler. 
Tbe engine works in a solid cast frame of the 
Corlies pattern, and the manner of mounting 
combines rigidity and simplicity, as will ho seen 
by a reference to the cut. 
In the horizontal, the engine is so placed as to 
avoid strain, and the cylinder being inside the 
dome, the pressure on the piston, it is said, is 
uniform with that shown on the steam-gauge. 
Economy in water 
and fuel, good wear¬ 
ing qualities, and 
careful workmanship, 
commend these en¬ 
gines for all purposes 
for which they are 
adapted.

POLAND CHINAS. 
This breed of swine variously known ub Magie, 
Poland-China and Butler Co., was originated by 
Mr. D. M. Magie, the present manager of the 
D. M. Magif. Co., 
Oxford, Ohio, and 
is the outcome of 
four distinct 
breeds, the Poland 
Big China. Irish 
Grazier and By- 
field. Their chief 
excellencies c o n- 
sist in their sus¬ 
ceptibility of be¬ 
ing well fattened 
at any age ; large 
growth when de¬ 
sirable, and the 
great amount of 
flesh laid on iu 
proportion to tbe 
food consumed. 
They sometimes 
dress 850 pouuds 
when n o older 
than ten or twelve 
months. The illus¬ 
tration conveys a 
just idea of these 
swine. They have 
long bodies, short 
legs, broad, 
Straight backs, and 
deep sides with 
square heavy hams 
and shoulders. 
They are large, 
dark in color, and 
the ears project 
over the eyea. 
Mr. Magie com¬ 
menced his exper¬ 
iments in 1837, 
and for thirty-five years the Poland Chinas nave 
been a distinct breed, and one of the most pop¬ 
ular in the States devoted to pork producing as a 
leading industry. 
These animals have of late attracted the at¬ 
tention of foreign breeders, and Mr J. Mcsson
