CARL FRIEDRICH AUGUST GItAMKE, OF STETTIN, GERMANY.

POTATO CLEANl NG AND SORTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 340,572, dated April 27, 1886.

Application filed May 9, 1883. Serial No. 94,454. (No model.) Patentediu Germany, April 22, 1881, No. 16,542, and in England April 28, 188?, No. 2,007.

To aZZ whom it may concern.-

Be it known that I, CARL FRIEDRICH AU? cus'r GRAMKE, a subject of the Emperor of Germany, residing at Stettin, in the German Empire, have invented a new and useful Potato Cleaning and Sorting Machine, (and for whichI have obtained a patent in Germany, N0.16,542, hearing date April 22, 1881, and in England, N 0. 2,007, hearing date April 28, 1882) of which the following is a specifica' tion.

The invention relates to improvements in machinery or apparatus for cleaning and sorting potatoes; and the objects of my improvements are to provide improved apparatus for the purpose. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 represents a plan of the entire machine. Fig. 2 is a side view. Fig. 3 represents the lifting device and hinged flaps. Fig. 4 is a sectional view of the hinged sieve e in Figs. 1 and 2. Figs. 5211(16 represent,on alarger scale, a front and side view of the hinged flaps. Fig. 7 shows a detached view of the screens, and Fig. 8 a cross-section thereof.

The hopper I), carried by the frame a of the apparatus, has a discharge-opening governed by a slide, at, actuated by a lever, 0, the position of which is fixed by means of the toothed segment 1). From the top of the frame a is suspended an inclined frame, a, by means of four rods, f. To this frame 0 a vibrating motion is imparted by means of the crank-handle t" and wheel h, imparting motion to the pinion k on the shaft 1, which actuates the bevel-pinions on, and thereby imparts a reciprocating motion to the frame 0 through the rods a and w, worked by the eccentrics r and s. I

The frame 0 is provided with a screen having meshes of two different degrees of fineness, as shown in Fig. 1, the finer meshes being next the hopper, so that on the potatoes falling from the latter onto the screen the smaller ones first pass through the screen, while the larger ones pass over and fall through the larger meshes, and those that are too large to pass through these roll down onto the table d. The screen has suspended from its under side a series of hinged flaps, g, which are pressed upward against the screen from time to time by means of the blocks h, carried by the traveling and endless band i passing around the small pulleys j, Fig. 3, carried by the spindles Z and m. This contrivance forces out any potatoes that may have stuck fast in the meshes.

Beneath the frame a is a second, 13, which is made to vibrate on a central pivot,k', by means of the rod 11, actuated by the aforesaid gearing i 9 h l and shaft 1). This frame contains two screens, 13 B", carried therein on pivots k k, so that they can be turned thereon into aninclined position by means of the hand-straps Z, whereby the potatoes are caused to roll into the bags I) on this or the other side of the apparatus, as may be desired, being discharged into the sacks through the spouts o". For holding the screens B B in an inclined position for this purpose weights m are connected to the hand-straps Z. The screens B B" act to remove any dirt from the potatoes, which dirt will fall onto the floor. The potatoes that do not pass through the meshes of the top screen are collected on the table d, having a perforated bottom, through which any dirt may fall. At the end of the table are open ings, through which the potatoes fall into sacks b.

The table (1 maybe adjusted to any desired inclined position by means of the quadrant strut'r. The charge of potatoes being placed in the hopper Z), passes through the regulated opening thereof onto the screens 0, on passing over which they are sorted, as described, and they pass to the lower screens and table d, and then into sacks b,supported by frames 0, having hooks d and chain c to supportthe frame 0.

Iclaiml. The combination, with the frame a, the spouts 0 and the screen for sorting, of the additional screens B B, provided with pivots k whereby they are capable of being inclined to either side in order to discharge the potatoes through said spouts.

2. The combination, with the frame a and provided with the flaps g, of the travelingthe sorting-screen provided with pivoted or band & and projections h, for the purpose hinged flaps g, of means for pressing said flaps specified.

upward against the under side of the screen, CARL FRIEDRICH AUGUST GRAMKE. 5 so as to force out any potatoes that may have Witnesses:

stuck fast in the meshes. PAUL DERRLICH,
