THE GENESEE FAEMEE. 



EMERY & CO.'S 



Oversiiot Threshing Machirit, Vi'Itli Vibrating 



and revolving Separators. 



THE above Threshers have been extensively manufactured 

 and sold by us for the past six years, and with a steadily in- 

 creasing demand. During the two years last past, and with 

 our latest Improved Railroad Powers, their sale has more 

 than doubled over the same length of time before. 



Although over two thousand of these Threshers have 

 been sold by us up to this time, and without exception have 

 given the fullest satisfaction as heretofore made, we can 

 safely say they are, as now made, worth at least 5(» per cent, 

 more than heretofore, and without any increase in prices 

 being charged for them. 



Their construction is such that the grain and straw are 

 carried by the cylinder from a level feeding-table, over and 

 between it and the concave, which is placed above instead 

 of below as is generally done in others. The cylinders being 

 26 to 30 inches long, and 14 inches diameter, are much 

 longer but smaller than those generally in use^giving more 

 room for feeding, in proportion to work done, and doing it 

 nearer the center of motion, and working easier, as the 

 smaller the diameter the greater the power. Again, we 

 require but about half the number of Spikes in the cylinder, 

 and an increased motion, so that the spikes may pass 

 through with a velocity sufBcient to take off all the grain. 



The concaves have an increased number of spikes, which 

 fiir both cylinder and concave are swedged into uniform 

 shape and size, from the best Swedes Iron. They are set 

 with an ineUnation which admits the straw and grain to 

 pass freely, and with as little breaking of the straw as is 

 consistent with a perfect separation of the grain — thus pro- 

 ducing a sort of stripping or carding process. The concave 

 is so confined as to be readily adjusted and present any de- 

 sired angle of the spikes to the grain, and also increase or 

 decrease the capacitj- of the throat, thereby retaining the 

 straw a longer or shorter space of time in passing, as the 

 condition and kinds of grain may require. By this arrange- 

 ment, there is a saving of power of from 30 to 50 per cent. 

 over the ordinary Threshers, whose spikes pass each other 

 at right angles, which operation necessarily breaks the 

 straw into many pieces at the expense of much power — a 

 process much more easily done with a good hay cutter with 

 sharp knives, than with the rounded edges which well 

 formed spikes present to the straw. The feeding-table is 

 level, allowing the feeder to stand upright and be little an- 

 noyed by dust, dirt, &c. The overshot'motion avoids acci- 

 dents to men or machine, (by preventing any stones, sticks, 

 &c., getting into it in feeding,) which frequently occur with 

 the inclined feeding-board. The grain by this motion is 

 elevated sufficiently to be thrown upon a large seive or sep- 

 arator, where it is separated from the straw arid falls through 

 upon the ground or floor, together with the fine chaff, dust, 

 &c., while the straw is discharged at the end of the separa- 

 tor, ready for stacking or binding. 



The shafts of our cylinders are made of solid cast steel, 

 manufactured and imported for us expressly for the purpose ; 

 and all tlie boxes or bearings are made of or lined with 

 Babbet metal. The boxes used by us are always of two 

 parts, in order to be adjusted as they may wear, or to vary 

 the position of the cylinder, as well as to allow them to be 

 removed, if necessary for cleaning or repair, without remov- 

 ing the pulleys or other parts of the machine. This is an 

 important advantage over those boxes which are made of a 

 sort of tube, and only removed by first removing the pulleys, 

 &c., &c., and are never adjustable to accommodate them- 

 selves to any wearing. 



The pulleys are polished and fitted to both ends of the 

 shaft and confined by nuts and screws, and with our India 

 nibbcr band, which we invariably use, form a perfectly air- 

 tight connection ; thereby bringing the atmospheric pres- 

 sure to our aid, and preventing any slipping of the band. 

 A band of this kind, say 30 feet long 3X inches wide, will 

 drive equally strong when four inches looser than if made 

 of leather. This kind of band requires little care, compared 

 with leather, is equally pliable in all temperatures, and is 

 not affected by dryness or wet, grease, acid, or dust It is 

 made with but one joint, and that smoothly cemented and 

 copper riveted, and is equally durable for straight bands as 

 leather, the difference in cost being a little in f;'ivor of India 

 rubber. The chief advantage of using these bands, is caus- 

 ing less stress upon the shafts, allowing them to run with 

 less friction and wear on bbth shafts and boxes. 



Cleaner and ThresUer, Combined. 



Diiring the past three years we have spared neither time 

 nor money in endeavoring to produce, at one and the same 

 time, a CLEANING THRESHER, which will perform as 

 well and rapidly as our Thresher and Separator, with the 



same force of men and team to operate it, while the increased 

 cost of such combination should not exceed the value of a 

 good fanning mill, say $'25 to $30. During the past two 

 seasons we have succeeded to our entire satisfaction in aU 

 respects excepting cost of construction, the increased ex- 

 pense of manufacturing being some fifty to seventy-five 

 doUars, and bringing the price fully up to that of Pitts' 

 celebrated Patent Thresher and Cleaner, which has been 

 extensively and favorably known throughout the whole 

 country for the past fifteen years; and when adapted for 

 two horses, well made, and driven by our two-horse power, 

 will do as well as any now in use, our own not excepted, 

 setting aside perhaps something in quantity of work done. 



The great excess of the demand being for our Threshers 

 and Separators instead of Cleaners, we are compelled to 

 confine ourselves and facilities chiefly to the former, making 

 Cleaners only to order, and at the price of one hundred dol- 

 lars each, instead of seventy-five, as heretofore advertised 

 by us. 



From our own observations, and the slow adoption of the 

 Cleaner combined, when used by farmers with bams, and 

 for their own purposes, we would not recommend them on 

 the ground of economy, as the grain can generally be 

 threshed better and faster with the Separator ; and the sim- 

 plicity of the one as compared with the other, together with 

 the difference of skill required in those attending both kinds, 

 is vastly in favor of the Thresher and Separator. Those 

 farmers using their straw for feeding, or selling in m.arket, 

 find it much more valuable when threshed with a Separa- 

 tor. It is entirely free from the dust, dirt, and fine chaflT 

 which is mixed thoroughly through the whole mass by the 

 current of air thrown from a Cleaner. 



In field threshing, and where time is of the greatest con- 

 sideration, and there is risk from exposure to weather, the 

 straw of little value, large Cleaners, with more men and 

 horses, are often preferable. 



We have received many complimentary letters concern- 

 ing our Thresher and Separator, and in every instance 

 where both have been used, the preference for economy has 

 been given the Thresher and Separator for farmers own use. 



We can not better express the general feeling among the 

 farmers concerning the relative advantages of Threshers 

 and Separators, and Threshers and Cleaners, than by giving 

 extracts from several correspondents who have seen and 

 used both. 



Extract from letter of Russel KUlioiirne, of Paris mil, 

 Oneida Co., N. Y. 



" Sirs — Since the first two hundred bushels of wheat 

 threshed witii your latest improved Railroad Horse Power 

 and Threshing Machine and Separator, they have per- 

 formed well. Two or three farmers, neighbors near me, 

 desire machines for their o-wn use. How soon can you ship 

 them after they are ordered, and can you sell them any less 

 on account of the lateness of the season ? I wish very much 

 to sell two or three of them here, if possible ; not only be- 

 cause I think the purchasers would be better pleased with 

 them, but because Mr. Osbom, Wheeler's agent, and who 

 has one of Wheeler's Two-Horse Power Threshers and 

 Winnower's here, is determined that none of yours shall be 

 sold if he can prevent it." 



In a subsequent letter, he again WTites us: "The more I 

 see of Wheeler's Power and Winnower, the more I don't 

 like it. They can thresh just about seventy-five bushels of 

 first rate wheat per day." 



Extra<rt of letter front' Wm. H. Chalmers, of West Oahcay, 

 Saratoga Co., N. Y. 



" Gentlemen — I have a small team, and with moderate 

 elevation, and without their drawing in harness, I put 

 through large sheaves of wheat at the'rate of one hundred 

 every ten minutes, threshing it thoroughlv. Much more 

 could be done for a short time; but I mean with the eleva- 

 tion and labor of team as I use in following threshing. I 

 firmly believe your improved Power Thresher and Separa- 

 tor will sujiersede anything I have seen. Many farmers 

 prefiT the Thresher and Separator to the Winnowers, as 

 grain can be threshed faster and better wlhout them— re- 

 quiring less men, thereby saving suf3cient time for cleaning 

 with a good Fanning Mill. I have seen one of Wheeler's 

 Horse Powers, with Thresher and Winnower, at work here, 

 threshing but one quarter as fast as I do with your machines. 

 An Eight-Horse Power, with Thresher and Cleaner, work- 

 ing in this vicinity, requiring twice as many men, is pro- 

 nounced, by those taking away the straw from both, to 

 thresh less per day than mine. I wish you to write me if 

 you have made any improvements since mine, and have 

 you Powers, &c., on hand, as I expect to sell some."
