CLEANING AND FSORCLINGr DEVICE FOR THRESHING-MACHINES.

Specification of Letters Patent.

Patented oct. 26, 1909.

Application led January 13, 1909. Serial No. 471,995.

To all whom fit may concern:v

Be it known that I, GUSTAV ERLINGER, J r., a subject of the Austro-Hungarian Empire, residing at Plank, Kamptal, Austria-IIungary, have invented a certain new and Improved Cleaning and Sorting Device for Threshing-Machines, of which the following is a specication.

The present invention has relation to a new or improved cleaning and sorting device for use with threshing machines, the object of the present improvements being to dispense with t-he use of fans, elevators, and sorting cylinders, thereby rendering the machine less complicated and more effective than hitherto.

In order that this invention may be clearly understood and more easily carried into practice, reference may be had to the appended explanatory sheet of drawings, on which Figure l is a longitudinal section of the device. Fig. 2 is a transverse section, the plane of section corresponding to the line B-B of F ig. l.

In an embodiment of the present device as arranged to clean the grain and sort the same into two grades or sizes, the grain is passed down an inclined chute a to a sieve c, such sieve being suspended by means of the pivoted links andreciprocated by any suitable means.

One portion c of the reciprocating sieve is provided with meshes corresponding to the larger grain, while the other portion Z consists of smaller meshes corresponding to the finer grain. The grain passing through the meshes c and CZ of the sieve, are collected and retained in the funnels e and f respectively, from which they are removed at intervals, or the funnels may have sacks attached thereto for the reception of the grain.

The sieve sections are made interchangeable in order that various sizes of grain may be sorted. The frame Z2 of the reciprocating sieve is arranged to fit closely or fairly so upon the bottom of the chambers 71, and z' the upper opening of which adjoins the suction chamber which communicates with a suction fan Z or its equivalent.

At the openings of the chambers h and c' are provided adjustable flap-valves a and a, the object of which is to regulate the velocity or suctionof the air passing through the chambers 7L and z'.

Above the sieve meshes Z and supported on the sides of the vibrating frame b are conducting channels o which communicate with an opening p at the extremity of the device, while the channels 0 also decrease the passage for the air current and thereby increase the velocity for the purpose herein after explained.

In the upper outlet passage to the suction device is arranged an air valve r controlled by a weight adjustably secured upon a pivoted lever, such valve being opened by an increase in the velocity of the induced air current, in order to regulate the current in the chambers to a constant velocity.

The device as hereinafter -described operates as follows The current of air induced by the fan Z being compelled to pass through the reciprocating sieve c by the grain which forms a oint, carries the finer waste into the chamber L and outlet pipe la and the small Train passes through the meshes c into the funnel c, the larger grain and waste being carried by the vibration of the sieve to the coarser meshes CZ where, by reason of the restricted area of the passage, and the consequent higher velocity of the air current the coarse waste is carried into the chamber c', in which the air expands and allows the waste to fall into the channels 0 while the grain falls through the meshes CZ of the reciprocating sieve and into the funnel. The reciprocation of the channels causes the large waste to be brought to the outlet p where it is discharged. If the suction should suddenlyl increase by reason of a variation in the speed of the fan, the air inlet valve 1' opens and thereby regulates the air current, preventing any grain being carried into the waste.

Having now described my invention, I declare that what I claim is In a cleaning and sorting device for use with threshing machines, the combination of sieve sections, means for reciprocating said sieve sections, means for producing a suction for cleaning the grain, a chamber which fits closely around said sieve so as to compel the air Current to pass therethrough7` means for feedlng and recelvlng the gram,Y

a member which s secured above one of the screen Sections and which has an aperture through which the coarse Waste is drawn, said member having also side portions onto which' thek Waste falls as the result of the decreased velocity of the air current brought about by increased areaV of the Chamber.` 10

Vlax-'witness whereof I have hereunto set my hand in the presence of tWo Witnesses.
