Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
"A trough is made like that of the ordinary straw cutting machine; in this, the straw to be cut or thrashed is placed, and carried towards one end, by a feeding cloth upon revolving rollers; a drum or cylinder, of from one to two feet in diameter, and from two to four feet in length, according to the width of the trough, to which its length must be equal, is made to revolve rapidly: the axis of this cylinder stands parallel to the end of the trough, and its periphery nearly touching it. When cutting is to be effected, knives reaching from end to end of the cylinder, are fixed at suitable distances upon it, and cut the straw as it is drawn forward; an iron or steel bar across the end of the trough sustaining it, and re-acting against the knives.
When wheat, &c., is to be thrashed, the cylinder with knives is removed, and one having beaters, formed of bars about an inch square, is substituted. These beaters form ridges upon and extend from end to end of the cylinder. Upon the shaft or axis of the cylinder, a heavy flywheel may be placed, which accelerates the motion of the cylinder.” When used for thrashing, screens, a winnower, &c. are appended, to operate in the usual manner.
The two operations by the one machine, your petitioner claims to be the sole inventor of. He also claims to be the sole inventor of the machine for cutting straw; and he also claims to be an improver on the machine for thrashing, by the application of the balance wheel, and the application of the screen and winnower."
Excepting in extraordinary cases, we intend hereafter to present the outlines of thrashing and washing machines, without making unwelcome reflections and invidious comparisons; as, were we freely to tell our thoughts in all instances, we are apprehensive that their projectors would frequently be inclined to try the operation of lathering, thrashing, and beating upon ourselves; and as, our intentions being always good, we should deprecate such a consummation, we are determined to pursue a prudent course, and avoid exciting the ire of the testy corps of inventors."
