Potato-Digger.
Patented Dec. 9, 1851.
UNITED STATES PATENT UEEICE.
DANIEL D. BELL, 0F WAVARSING, NEI/V YORK.
IMPROVEMENT IN POTATO-DIGGERS.
Specification forming part of Letters Patent No. 8,574, dated December 9,1851.
To all 'whom it may concern:
v Be it known that'I, DANIEL D. BELL, ot' Wawarsing, in the county of Ulster and State of New York, have invented a new Machine for Digging Potatoes, Src.; and I do hereby declare the following to be a full, clear, and exact description ot' the same, reference being had to the annexed drawing, making a part of this specification, in which the figure is a view in perspective of my machine.
My invention consists in a machine for digging potatoes from the eld by horse or other power. In the old methods ot' harvesting the loss is very considerable, as the potatoes after being plowed up are still commingled with the earth to such a degree that the ground must be gone over several times in order to secure a fair proportion. A very considerable number are always left scattered about, as more minute gathering would not pay for the time consumed in effecting it.
My machine consists of a frame-work supported on four wheels. Upon this, inthe lirst place, is a cutting-cylinder to cutoff the tops. A diggin gcylinder follows, which throws the potatoes up out ofthe ground mixed with the earth, stubble, Ste., to some degree, and discharges the whole upon a set ofriddles or other sifting arrangements, by which the dirt is separated and the clear potatoes discharged at the back end into a trough, or are allowed to fall back upon the ground completely divested ot' dirt and stalks, whence they are easily gathered into the cart following the machine.
The machine is constructed as follows: A frame-work of two parts isfirst formed, on which all the working parts are supported, A representing the front frame and B the back frame. These two frames are attached together by a bolt similar to aking-boltin a common wagon. All the wheels are connected to the axles, so that the axle will revolve with them. The revolution ofthe fore wheels gives motion to the cutting-cylinder and digging-cylinder before mentioned, and the rotation of the hind wheels gives motion to shake the riddles or sieves.
The cutting-cylinder is seen at D. It is a drum shaped like two frusta of cones joined at their larger bases. Upon this a series of blades is put parallel to each other, as shown. A pinion gearing into a spur-wheel upon the axle of the fore wheels gives it motion as the machine travels along. The blades cut oft' the roots bytwo motions-viz., that caused by the onward motion ofthe machine and also by the rotary motion of the euttingcylinder. The cutting-cylinder is supported upon two arms or levers, E E, having their fulcra coincident with the fore axle, as shown. A bent bar, a, passing over the top, connects the two ends together, so that by operating this end of thelevers or arms the cutting-cylinder can be elevated or depressed as may be required.
At G is the diggin g-cylinder. On the circumference a series offorks are arranged, as shown. rlhe number of teeth in the forks, as well as the velocity of the cylinder itself', is so calculated that all the potatoes will be taken up and thrown over upon the riddles. Immediately over the diggin g-cylinder a platform is raised, supported upon four posts and cross-pieces, l). The top ooring is removed in order to show other parts. Upon this platform the driver.
stands.
H represents a series ot' bars placed between the cutting and digging cylinders. They are movable up and down by a cross-bar, c, and springs d. When they are to be used the driver puts his` feet upon the bar c and presses all the bars down, the pointed ends going to the ground. The use of these is to catch anything which the driver may seein the path of the machine calculated to interfere with the diggin gcylinder.
I are the riddles, the top one shown inclined toward the back. They are agitated by cams or other suitable projections at e upon the back axle.
It was before remarked that the two frames A and B were kept togetherV by a king-bolt, so thatinstead of the fore axle turning, as is usual, the bend for turning is formed here. It is evident that some other means must be employed to sustain the frame, as otherwise the strain the frame can be raised or lowered within cer-l tain limits. The supporting of the frame and the raising orlowerin g are effected by connecting the two parts by a rigid support or pole This pole is seen extending over the whole.
at K, and is attached to the forward crosspiece of the platform b by a bolt. The back end rests upon a cross-bar, t', which bar is capable of being raised or lowered on the two vcrtical supports shown. The cross-bar b then becomes the fulcrum, and it will be seen that the whole weight of the two inner ends of the frame A Bis sustained by the cross-bar b and the pole K, the king-bolt keeping the two parts together and the other supporting the weight. The raising or lowering of the back end of lthe pole K gives the whole adjustment referred to`viz., the np-and-down motionsand these are very important, for by lowering the movable end of the pole K the depth of immersion of the forks of the diggin g-cylinder is increased, and, vice versa, by raising it that also is raised out of the ground. The permanent set is made by the bar i; but an attendant following the machine can, in the case ot' any obstruction, raise the cylinder as may be required to clear it. The raising or lowering of the digging-cylinder, however, slightly acts upon the cuttingcylinder. This, however, is
kept at the proper adjustment bythe driver standing upon the staging, who raises orlowers the bar a as required.
In operation the machine is drawn over the hills or rows according tothe manner in which the potatoes were planted, the forks in the digging-cylinder being set so as to take up an entire hill in the distance passed over. It should be remarked that in turning, the pole K being hinged at the front end, the free movement of the two parts Yis not affected, as the bar b slides along over a friction-roller placed in the pole, as shown.
What I claim as of my own invention, and desire to secure by Letters Patent of the United States, `is
The arrangement and combination of the cutting and digging cylinders with riddles, in the manner herein set forth.-
DANIEL D. BELL.
