BEAN -ASSORTING MACHINE.

To all whom it may concern:

Be it known that I, AUGUsTUs A. MARTUS, a citizen of the United States, residing at Brown City, in the county of Sanilac and State of Michigan, have invented certain new and useful Improvements in Assorting Machines, of which the following is a specification, reference being had to the drawings.

This invention relates to certain improvements in bean assorting machines and it is an object of the invention to provide a device of this general character having novel and improved means whereby the bad or cull beans may be readily separated.

It is also an object of the invention to provide a device of this general character including a hopper discharging .upon an endless carrier and wherein said carrier comprises a plurality of flexible strands through which the bad or cull beans may be readily forced therebetween by a slight pressure thereon.

The invention also has for an object to provide a novel and improved device of this general character including a hopper discharging upon an endless separating member together with means for controlling the discharge of the beans upon the member.

The invention consists in the details of construction and in the combination and arrengement of the several parts of my improved bean assor-ting machine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in side elevation of a bean assorting machine constructed in accordance with an embodiment of my invention;

Fig. 2 is a view in front elevation of the device as herein disclosed;

Fig. 3 is a vertical longitudinal sectional view of the device as herein embodied;

Fig. 4; is a sectional view taken substan- 'tially on the line 4-4: of Fig. 3;

the assorting member as herein employed;

Fig. 6 is a fragmentary view in top plan of the assorting member as disclosed in Fig. 5; and

Fig. 7 is an enlarged fragmentary detail illustrating the mounting of the valve coacting with the hopper.

As disclosed in the accompanying drawings H denotes a hopper supported by two sills 2 arranged substantially in horizontal alinement'and in predetegpined spaced] relation. The sills 2 are supported at the desired elevation through the medium of the side frames 3. Coacting with the side frames 3 are the horizontally disposed brace members 4. The hopper H comprises the end members 5, the side members 6 and the downwardly and inwardly inclined bottom member 7 which terminates inwardly of the side member 6. The lower portion of the side member 6 is provided with the opening 8 through which the beans to be assorted are discharged. The end members 5 adjacent the side member 6 are provided in their opposed faces with the inwardly and downwardly inclined grooves 9 in which tions of the valve 10 which is preferably maintained in various elevations by friction.

Supported by the end members 5 of the hopper H below the lower or forward marginal portion of the inclined bottom 7 is the rod 11 and pivotally, engaged with the rod 11 is a chute 12 of a width to eX- tend through the opening 8 in the side member 6 and the forward marginal portion of the chute 12 contacts by gravity with the periphery of the ratchet member 14: fixed to the shaft 15. The shaft 15 is rotatably supported by the forwardly directed exten sion 16 carried by the hopper H. As the shaft 15 is rotated the ratchet member 14: carried thereby will vibrate the chute 12 whereby the discharge of the beans from said chute is effected and which also results in an effective distribution of the beans so that the same will be received to best advantage by the separating member M to'be' hereinafter more particularly referred to.

The chute 12 is of a length substantially equal to the space between the end walls 5 of the hopper H and the end marginal portions of said chute are provided with the upstanding flanges 17 whereby the beans delivered to the chute from the hopper H are prevented from obstructing or interfering with the required vibration of the chute.

As herein disclosed an end portion of the shaft 15 is provided with a pulley 18 around which is directed a belt 19 and the belt 19 isalso directed around a pulley 20 fixed to the shaft 21 disposed transversely of and rotatably supported by a rear portion of the frame F. The frame F has the hopper H resting directly upon the rear portion thereof and said frame F is secured to the sills 2 hereinbefore referred to.- The shaft 21 adjacent the pulley 20- is provided with a balance wheel 22 and operatively connected sprocket wheels 25 and disposed over said sprockets are the endless chains 26. The chains. 26'also pass over the pulleys 27 carried by the shaft 28 disposed transversely of and supported by the forward end portion of the frame F. The chains then extend downwardly and over the pulleys 29 carried by the shaft 28 rotatably supported by the side frames 3. By this arrangement, the upper stretches of the chain travel-in substantially a horizontal path and in a direction away from the hopper H.

Transversely alined links of chains 26 are connected by the rods 30 and encircling each of said rods is a coil spring 31 of an expansible' type.

'Overlying the rods 30 is a plurality of flexible strands 32 preferably cord and which are arranged in substantial parallelism. These strands 32 are threaded through the convolutions of the springs 31 and overlie the rods 30. The strands between adjacent rods may be readily forced apart by im- 'posing slight pressure upon the beans supported between adjacent strands.

In practice the beans are discharged over 7 the chute 12 and as the same are carried forwardly it is only necessary for the operator to-impose a slight pressure by a finger upon a bad "or cull bean and the same will be forced between adjacent strands 32 and thereby separated from the prime or good beans. Positioned between the stretches of v the chains26 is the collecting chamber C provided with the laterally directed discharge spout 33 through which the separated culls or beans are delivered.

34: denotes the downwardly and rear- Wardly inclined chute disposed in a direction longitudinally of the frame F and the prime or good beans are, delivered into the upper end thereof from the upper stretch of the assortingmember as afforded by the chains 26 and the elements carried thereby.

Also positioned between the stretches of the chains 26 is a hopper 35. This hopper 35 is also positioned directly below the discharge end of the chute 12 so that as the beans are delivered upon the strands 32,

sand and other small matter will pass between the strands 32 and' be collected within the hopper 35. The hopper 35 is provided with the discharge chute 36 which extends downwardly on a predetermined incline and preferably in a direction away from the spout 33 hereinbefore referred to.

I also find it of advantage to arrange within the hopper H above the valve 10 a stationary guide plate 37 delivering upon the inclined bottom 7. The guide plate 37 serves to relieve the valve 10 of the weight of the beans within the hopper H so that the valve 10 may be manipulated with facility.

From the foregoing description, it is thought to be obvious that a bean assorting machine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my in vention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:
