LOUIS HOLLAND-LETZ, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNA- TIONAL HARVESTER COMPANY, OF CHICAGO, ILLINOIS, A CORPORA- TION OF NEW JERSEY.

GRAIN-CLEANER.

SPECIFICATION forming part of Letters Patent-No. 778,970, dated January 3, 1905.

Application filed September 6, 1904. Serial No. 223,319.

To all whom, it may concern: I

Beit known that I, LoUIs HoLLAND-LETZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Cleaners, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The invention relates to corn huskers and shredders, and more particularly to a graincleaning mechanism for that class of machines.

The object of the invention is to provide a cleaning mechanism ldesigned to separate the grain from the shredded fodder, and is particularly applicable to machines of the class described when used for shredding Kafir corn.

In the drawings illustrating the invention, Figure 1 is a partial side elevation of a corn husker and shredder embodying my improvements. Fig. 2 represents a section in part on line A B of Fig. 1. Fig. 3 represents an enlarged side elevation of the cleaning mechanism from the side opposite to that shown in Fig. 1. Fig. 4 is a sectional elevation of a part of Fig. 3. Fig. 5 is a section on line C D of Fig. 3.

The same reference-numerals designate like parts throughout the various figures.

1 represents the body of the machine having the usual feed-table, snapping and husking rolls, and shredder-head, also any of the common cleaning devices located in the body of the machine and designed to separate the shelled corn from the shredded fodder and deliver it into the lower end of the elevator 2, having the endless carrier 3 to convey the grain upward to the bagging attachment,

In machines of the above type it has been found that when they are operating on Kaiir corn the cleaning and separating has not been as complete as desired, and the purpose of this improvement is to provide an auxiliary cleaning attachment at the upper end of the elevator to operate upon the grain before it is conducted to the bagging mechanism.

The mechanism consists of a suitable casing 4, attached to the body of the machine and to the elevator. Within the casing is mounted a fan 5, having the ends of its supporting-shaft journaled in the opposite sides of the casing. The shaft that supports the sprocket-wheel at the upper end of the elevator 2 and over which the endless carrier is run projects beyond its journal at one end and is provided with a band-pulley 6. On the corresponding end of the fan-shaft there is mounted a pulley 7, and a belt 8 passes around the two pulleys and transmits motion to the fan-shaft.

A supplemental casing 9 partially surrounds the fan, and above the supplemental casing is mounted a vibrating sieve 10. The sieve is provided with side bars that bend upward at their inner ends, as shown in Fig. 4, and the perforations are in what may be called the horizontal part, the upturned portion operating as a chute to conduct the grain over the top of the fan. The sieve is supported at its rear end by the U-shaped rod 11, that has its upper member journaled in the sides of the casing 4, with the sieve resting upon the lower member, as shown in Figs. 2 and 3. A lever 12 is secured to theprojecting ends of the rod, and an eccentric 18 is secured to the fanshaft adjacent the driving-pulley or the eccentric may be integral with the pulley. The sides of the casing4 are provided with slots for the reception of the lower member of the U- shaped rod 11 that are concentric with the axis of its upper member. The lever 12 embraces the eccentric in a manner to receive a vibratory movement through the operation of the'latter and transmits such movement to the sieve by means of the U-shaped rod. The outer end of the sieve is adjustably supported by means of flexible U-shaped links 14, having their longer ends attached to the frame of the sieve and their shorter ends doubled to.- gether, forming a lengthwise slot through which the fastening means passes and secures the links to the sides of the casing 4. By means of-these adjustable links the outer end of the sieve may be adjusted upward or downward, as required.

15 designates the opening at the upper end of the elevator 2, through which the material is delivered to the sieve l0. The casing 4 is covered for a portion in front of the deliveryopening, and depending from said cover is a xed curtain 16, located a shortdistancefrom the delivery-opening between the sides of the casing and adapted to deflect the material toward the sieve, and a flap-curtain 17 is hung upon the lower end of the fixed curtain for the purpose of retarding the flow of material upon the sieve. The material is delivered to the sieve, and by the vibrating motion thereof and the blast from the fan the grain is separated from the remainder and falling through the sieve is conducted to the spout 18 to be conducted into bags or otherwise disposed of.

What I claim, and desire to secure by Let-v ters Patent, is-

1. In a machine of the class described, the combination of an endless elevator-carrier that receives the shelled grain from the machine, a cleaning mechanism mounted at the delivery end of the elevator comprising a casing, a fan mounted to rotate therein, a sieve located above said fan, said sieve being supported by a U-shaped rod having its legs passing through the sides of the casing, an arm secured to the projecting ends of the legs, and means connected with the fan for vibrating said arm.

2. In a machine of the class described, the combination of an elevator that receives the shelled grain from the machine, a cleaning mechanism mounted at the delivery end of the elevator comprising a fan having' its axle journaled in the sides of a suitable casing, a vibrating sieve mounted above said fan and adapted to receive the grain from said elevator, said sieve being supported adjacent the elevator in a manner to swing with the supporting member, and its opposite end supported by U-shaped flexible members having one leg of each pivotally connected with the sieve upon opposite sides, and the other leg of each secured to the sides of the casing.

3. In a machine of the class described, the combination of an elevator that receives the shelled grain from the machine, a cleaning device mounted at the delivery end of the elevator comprising a fan having its axle journaled in the sides of a suitable casing, a vibrating sieve mounted above said fan and adapted to receive the grain from said elevator, said sieve being supported adjacent the elevator in a manner to swing with the supporting member, and its opposite end supported by U-shaped exible members having one leg of each pivotally connected with the sieve upon opposite sides, and the other leg of each member adjustably secured to the sides ot' the casing.

4. In a machine of the class described, a secondary cleaning device located to receive the grain after it has passed through the primary cleaning devices, comprising a fan mounted upon an axle, a fan-casing, said axle journaledv in the sides of said fan-casing, a vibrating sieve suitably mounted above said fan, an eccentric mounted on the axle of the fan, a lever pivoted on the side 'of the casing, and connected with the said eccentric and with said sieve, in a manner to vibrate said lever when the fan is operated.

In witness whereof I hereto aix my signature in presence of two witnesses.

LOUIS HOLLAND-LEITZ.
