IMPROVEMENT IN THRASHlNG-MACHINES.
Specification tbrniing part of Letters Patent No. 29,095, dated July it). lslit Reissue No. 1.2 I 8. dated August lit, ltjtil.
To all whom, it may concern:
Be it known that l, S. E. UVIAT'I, of Rich- Improvements in (lrain-Thrashing Machines;
and I do hereby declare that the following is l a full, clear, and exact description of the j the pulleys also extend across the month of same, reference being bad to the annexed drawings, making part of this specification, in
1 of the flue.
Figure 1 is a side elevation of a grain thrasher and separator combined, with my I improvements attached; Fig. top view of the same; Fig. 3, a rear end view of the same, and Fig. 4 a front end view of the same.
Similar letters of reference indicate corresponding parts in the several figures.
a plan or j flue and the top ofthe eylimler-ease. Above the cylinder is placed the mouth I of the tine, in which revolves the screen J. This screen consists of rods, or their equivalents, extending across the mouth of the tlue, and are attached to the belts K K, which pass over the pulleys L L L L. The shafts oi the flue, and have their hearings in the sides This revolvingscreen is operated bya belt from the cylinder-shaft to the pulley M. The screen J is for the purpose of preventing straw and chat! from passinginto the flue and pipes as it is thrown up when teed ing-a result which would tend to clog up the This invention consists in applying a suc- 1 tion tube or tubes to a grain-thrashing machine in such relation with the heater or thrashing cylinder that all dust evolved by I the operation of thrashing will be drawn into the suction tube or tubes and expelled from the machine in such a manner that the operator cannot inhale any portion of the dust, nor be in the least exposed to the same.
The invention further consists in the employment or use of a feeding-apron or guardscreen arranged in such relation with the heater or thrashing cylinder as to greatly facilitate the manual operation of feeding the r and chaff are more or less tilled up with grain to the machine, and also preventing the tlue and pipes thereof.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A indicates the general view of a thrasher and separator combined, with the usual appendages belonging to such a machine. I attach two side pipes, O G, the lower ends of which connect with and terminate in the fan-case D, Figs. 1, 2, and 3. At the lower ends of the pipes are doors or slides E, for the convenience of oiling the fan-shaft bearings. The upper ends of the pipes U 0 connect with the transverse pipe F, Figs. 2 and 4, and this transverse pipe connects with and opens into the flue H, under which revolves the thrashing cylinder, (indicated at G, Fig. 1.) Directly over the cylinder is the floor of the manner.
pipes. The screen revolves in the direction to convey the straw down toward the cylinder G.
The wheat is placed upon the table N and fed into the machine, where it is thrashed, and the grain, straw,and chal't' separated and discharged from the machine in the ordinary During the operation a strong cur rent of air is produced by the great velocity with which the cylinder (l is required to re- "0] ve. This strong current ot" air causes the dust produced in thrashing to envelop the whole machine and the persons attending it, and consequently the attending of a thrashing-machine is not only disagre able, but highly preiudical to health. As the passages f'roni the cylinder (l for straw, grain,
material when the machine is at work, the current of air produced by the cylinder cannot therefore cseape through these passages, but will rush out directly from the cylinder close to the persons feeding the machine, and the faster the machine is worked the more are the passages tilled up and consequently more dust raised or evolved, and it requires high speed to thrash with the desired effect. The dust raised or evolved in thrashing is produced by the cylinder G and the teeth near which the attendants are constantly employed in feeding the machine; and as the dust issues from the eylindeucase it gives and is conveyed by a current ot'air into the month l of the tine, thence to the crosspipe l'], and through the side pipcs,UG, into the fan-case l), as indicated by the arrows. From the case 1) the dust is blown out to the end oi the machinebythe fan 0. (Seen in Fig. Ii.) This inductioncurrentoi. air, which passes into the month of the line, is caused by the fan. Consequently all the dust which arises is carried ott' through the tine, so that the persons attending the machine are in no way inconvenienced by the dust, as has been t'ound by practical tests. It is also found that when thrashing in a building the room is free from dust when compared with the old practice.
\\'ith my improvement the dust may be conveyed outside of the building by having the proper draft, so that all persons in the building are benetitted.
\Vith slight changes in regard to the arrangement of the pipes my improvement may be applied to all kinds of machines used for 1 this purpose.
In the tine H is placed a damper or valve, as indicated at P in Figs. 1 and 2, which works or turns upon a hinge or joint on each end in the sides of the tine, as indicated at (i. This valve will till the whole aperture of the tine when closed. The cord It is attached to the valve for the purpose of operating it.
Thus with my improvement the evil and inconvenience arising from the dust in thrashing are removed, aml the dust is diseharged from the machine with the chat't', tve. Also the regulation ot the dral't o1 wind t'or cleaning the grain is more readily and etl'eetnally accomplished than by the ordinary means.
1 The feeding-apron or sereen J is also an imin the dust evolved during the operation of t thrashing, and discharging the same. at any convenient point, tree from the operators or atl tendants, when arranged and operatingsnb Bv means of this valve the person tending the machine can easily control the quantity ot" draft required to clean the grain by a slight movement of the cord on a word from the lneasnrer. The draft is easily and quickly gaged by the feeder. In the old way the draft is gaged by the measnrer passing from one side ot the machine to theother and moving the shutters at the ends of the tan case.
stantially as set forth.
