W. MANGELSDORF in LAUBAN. Potato harvesting machine.

Patented in the German Empire on September 6, 1877. Longest duration: June 27, 1892.

The new potato harvesting machine is, like all agricultural machinery, the same or built with a similar name for the purpose of lifting the potatoes out of the ground, the same to free from the attached earth and to lay it down on the 'surface of the arable land so that the tubers are collected by few human hands in the least possible time can be.

To achieve this, the machine has the drawings on the enclosed 2 sheets of paper and in the form and arrangement shown in the description below.

It shows:

Sheet I a longitudinal section and side view.

Sheet II shows the basic outline of the machine with a view of the endless chain from below and above.

Sheet II, Fig. 1, the front view; Fig. 2, a cross section through the coulter; Fig. 3 and 4, the endless chain.

The same letters always denote the. same organs. .

The machine, which rests on four wheels, has a track width of 65 cm and is used for Time only one potato dam.

The latter is constructed in a peculiar manner by means of one The crowd broke up and the earth of it with its contents, the potatoes, opened a rising, rust-like, openwork, endless chain is pushed, the latter by sprockets driven, the earth together with the potatoes carried to a certain height in order to keep them from to drop from here onto a swinging sieve mechanism.

In this way a great part of the earth is already through the openings of the chain removed, while the last remainder of it is removed by the vibrating sieve, so that the cleaned potato tubers fall down from the latter and onto the surface of the earth come to rest together in a narrow strip.

Serves as a connecting member of the front wheels A with the rear wheels B and B ', and as a carrier of other parts of a strong, wrought iron frame C, which is closed at the front end by a gufseisernen web D and receives the traction device in its vertical axis.

This pulling device consists of a vertical round iron rod E to which the wrought-iron axis F of the front running wheels A is attached.

The rod E is surrounded by a tubular rotating rack G and is encompassed by the sleeves of the tension bracket H above and below the latter.

The drawbar is with seven, in a vertical provided holes in which the tow hook is hung.

A small toothed wheel g works together with the toothed rack G , which sits with the hand wheel J on the shaft i.

By means of this device one is able to raise or lower the front part of the whole machine as required, whereby a shallower or deeper engagement of the blade K, or a complete raising of it for the transport, is achieved.

To lock the machine at the set height and to relieve the gear mechanism g , the pins g ¹ , which are inserted into corresponding holes in the web D and are arranged so that the rack and with it the front end can rotate freely.

The coulter K, which is attached to two bent-down arms of the frame C , is provided at its front end with a point k which can easily be exchanged and for this purpose is only held by a wooden stake /.

At its rear end, the coulter has four movable flaps m, which transfer the soil and the potato tubers to the endless chain M.

The flaps m are broken so that earth can fall through here.

The flock is specially designed to prevent damage to the potato tubers are excluded as far as possible.

The endless chain is composed of 28 rust-like openwork plates, which are attached to each end have a tenon and here with the help of wrought-iron pins with the two related panels.

Claims (1)

The pins mentioned lie in the gaps between the teeth of the four chain wheels h on the shafts η and ο. The chain wheels on the shaft ο drive the chain, while the wheels on the shaft 11 only serve to guide the chain. The operation of the shaft ο is caused by the gears ede and /, from the rear impeller B of the machine, to which the gear c is firmly connected. During the transport of the machine, the chain is switched off by bringing the angle lever / gear wheel d out of engagement with gear wheel c . The locking of the angle lever p in the correct position takes place by pins, as shown on sheet II. The gears d and e sit on the shaft g, the bearings of which, like those of the shafts ο and η, are screwed to the frame C. The bearings of the shaft ti have slidable inserts which can be adjusted by means of screws and thus allow the chain to be inserted and tensioned. So that the potatoes cannot fall sideways from the chain and no earth gets between the drive pins of the chain, the chain is limited on both sides by angled sheets r. As mentioned above, the potatoes and the earth still adhering to them get from the chain to the vibrating sieve N, which is suspended from the cross pieces t of the frame C by four steel springs ί and is set in oscillating motion by the eccentric O sitting on the shaft u . The shaft u rests in bearings also attached to the frame C and carries a gear d, which can be disengaged by the lever / * and is driven by the gear c located on the rear running wheel B. Patent claim: The production of a potato harvesting machine, which by means of a peculiarly constructed flock breaks open the potato dam, the contents of it, earth and Potato tubers on a peculiarly constructed, endless chain, the potatoes here freed from the adhering earth and the cleaning process on a vibrating sieve finished, from which the cleaned tubers fall to the ground in a narrow strip. For this purpose 2 sheets of drawings.
