EMERY'S PATENT 
TWO-ECORSE RAILROAD DE»O^W3ESH., 
IN OPERATION "WITH THE 
OVERSHOT THRESHER AND CLEANER COMBINED. 
Plate I. 
Section 1. The Proprietors having been for Twenty Years engaged in the manufacture and 
sale of Agricultural Implements and Machinery, and by traveling, exhibiting and attending 
Exhibitions, become familiar with the customs and necessities of the agricultural commu- 
nity throughout this country, as well as that of all parts of the world, new suggestions have 
continually presented themselves for improvements in many departments, and they have 
as constantly endeavored to Invent and Improve, as well as to Introduce, better Agricultural 
Machines, with what success it is needless here to enumerate. 
§ 2. It is but just to say that of all the numerous inventions and improvements made by 
them, the application of the Power of Horses, Oxen, &c, to the various purposes where 
heretofore only manual labor was considered available, has attracted and received much the 
greatest share of attention, and especially the so-called Horse Power on the Endless 
Chain principle. This, as in the engraving, is operated by the gravity and travel of the 
Horses alone ; and when once accustomed to them, no harness should ever be used. 
§ 3. This Power having gained a world-wide reputation and introduction, it would 
seem almost useless to enter into detail of its construction, and in doing so only some of the 
prominent features which characterize it from all others will be referred to. 
§ 4. Among the principal improvements over others before in use are the application of 
wheels of greater diameter, which generate the force and motion, and using connecting and 
multiplying cog wheels and shafts, by which an indefinite variety of forces and velocities of 
the band wheel may be obtained, while the travel and labor of the horses remain unchanged ; 
and at the same time the several gears and shafts having a corresponding strength to each 
other, as the ratio of the squares of their several velocities require, thereby securing the 
greatest ease in working, greater durability, and at the same time adapting them to every 
possible want of the farmer, planter or mechanic. 
§ 5. The perfect and at the same time simple adjustability of all the working parts of the 
Horse Power, by which the best possible results may be obtained at all times, without regard 
to amount of use or wear, is superior to that of any others ever made, as nearly ten years' 
constant and extensive use has demonstrated, not an instance being known where they have 
become useless and inefficient from any amount of wear of the several working parts. 
j 6. In this Power all the gearing is removed from under the horses, and inside the 
power to the outside, where it can at all times be seen and cared for, and readily attached 
or transposed for the various purposes for which it is to be used, as also from side to side 
of the Power, as is desired. 
§ 7. All the several gear and band wheels are held firmly upon their shafts by means of 
strong coupling fittings and heavy screw nuts on the ends of the shafts themselves, similar 
to the nuts used to confine the wheel of a wagon to its axle, thereby avoiding the necessity 
of ever removing, changing or transposing the shafts themselves. 
§ 8. All the small shafts which carry the links and small wheels of the endless platform 
are carefully turned to fit closely in them ; and at the same time the fitting in the wheel 
being smaller than in the link, a shoulder is formed on the shafts, which allows the wheels 
to fit flush on the shafts, and no more, thereby insuring the exact position of the wheels on 
the tracks and the small shafts themselves, and at the same time allowing all the freedom 
requisite to the links and flooring planks, which are fitted into them loosely, and avoid any 
binding and friction of the links of the chain upon themselves, the shafts or wheels. 
§ 9. The Powers also are the only ones provided with heavy cast iron flanged track 
throughout the entire circuit of the small wheels, both last features being of great utility. 
§ 10. As these Horse Powers have gained an enviable position and reputation, they are very 
closely imitated by several other manufacturers, and ottered to the public, and are not un- 
frequentiy represented as the genuine Power, which has in many instances had the intended 
effect to palm off a much inferior article. Again, by a cheaper cost of construction, and 
holding out greater inducements to dealers and agents, in the way of larger commissions, &c, 
than the profits of the genuine Power can afford, induce them to purchase the inferior and 
infringing machines, to sell to their unsuspecting customers. Therefore, in order to enable 
any person to distinguish the genuine Power, it is only necessary to examine if the letters or 
words " Emery," or " Emery's Patent," are in raised letters on the castings of the hubs of 
the band wheel, on the links and wheels of the endless chain and other castings; also if the 
small shafts of the chain have a smaller bearing in the wheels than in the links, with a 
shoulder for the wheels to run against ; that the several gears and pulleys are confined by 
means of large nuts and screws on the ends of the main shafts, outside the said pulleys and 
gears ; that all the four couplings of both main shafts, also of band and gear wheels, are 
uniform, admitting of all being transposed for different degrees of force and velocity, and 
from side to side, and without removing the main shafts, by simply removing their nuts ; and 
that the cast iron flange tracks upon which the wheels travel are continued the whole length 
of their lower or return circuit., 
Price of Two Horse Power and Pulley with extras for renewing same, $120. 
One do do do 90.
