Application October 4, 1950,.Serial No. 188,399
10 Claims.
1 The. invention relates to improvements in fiber transfer and cleaning, means. They present invention is a continuation-im art of my pending application Serial No. 598,043,, filed June 7, 1945,,
now abandoned, entitled Cotton Picker, and as to some of the features hereindisclosed is an improvement on the disclosure of my prior Patents Nos. 1,961,447 and 2,484,524.
In accordance withthe disclosure of the aforesaidv application Serial No. 598,043, and of my Patent No. 2,484,524, a powerful air blast is employed for blowing the bolls of growing cotton against a toothed picker unit located at or near the inlet, of a fiber transfer passage. The cotton picking unit is of such construction that it will strip the-fibers from the cotton bolls and deliver the fibers to the transfer passage, and will at the same time allow the air blast to pass freely through the unit into the transfer passage, where such blast serves as a. medium for conveying the cotton fibers to another location, such as a storage, hopper carried by the vehicle on which the cotton picker is mounted.
While a powerful, air blast is required for blowing the cotton bolls against the picking unit, it is desirable to release some of the air pressure during transfer of the fibers to their destination, and accordingly the transfer passage may be open at the top, bottom and both ends, and, if desired, relief openings may also be provided in the side walls of the transfer passage. While passing through the passage a portion of the trash may be separated from the fibers and allowed to drop by gravity as the air blast diminishes in intensity.
As disclosed in my aforesaid application Serial No... 5%,043, and. in.l2atent ,l lo. 2,434,524,, the cotton,flb rs,, after moving a su stantially hor .zont l. direction hrough. t etr n f r p ss are brought into contact with a rotatable spirally spoked centrifugal transfer member which, is so formed and operated as to permit particles of dust and trash to pass therethrough while retaining the fibers, and then centrifugally discharging them at a high rate of speed through a delivery passage extending at an angle to the first or inlet portion of the transfer passage, said delivery portion of the transfer passage leading to any suitable location, such as a storage hopper.
Thefibers, driven by, the original air l enga the centrifugal transfer and, cleaning; membersubstantially axially and are discharged peripherally by said transfer member into thesecond or delivery portion of the, transfer passage. This centr f l t a s er s feni gmgmber co stitutes an important feature of the present invention.
While the invention is applicable to the particular co'ton picker disclosed in my prior application and in Patent- No. 2,484,524, it will. be apparent that the invention is of more general application and that the centrifugal transfer and cleaning member may be used in other connections where it is desired to change the direction of movement of air-borne fibers or the like while at the same time separating therefrom particles of dust, trash and the like.
The invention will be more readily understood by reference to the accompanying drawings and the following detailed description, in which specifio embodiments of the inventive thought are set forth by way of illustration rather than by way of limitation.
In the drawings:
Fig. 1 is a diagrammatic view showing a fiber transfer passage including an inlet portion and a delivery portion extending at an angle thereto, with my improved centrifugal transfer and cleaning unit;
Fig. 2 is a side elevational view of the centriugal transfer and cleaning unit. v a
Fig. 3 is a front view of thecentrifugal transfer and cleaning unit, a portion only of the spiral spokes being shown;
Fig. 4 is a detail on the line 4-4 of Fig. 3;
Fig. 5 is a top plan view largely diagrammatic in character showing the application of the invention to a cotton picker similar to that shown in my Patent No. 2,484,524, parts being shown in section;
Fig. 6 is a central vertical section of the same, partsbeing shown in elevation;
Fig. '7 is a view similar to Fig. 6 suggesting the application of the invention to a cotton picker of the type disclosed in my prior Patent No. 1,961,447, part of the transfer passage being broken away.
To illustrate the invention in its simplest terms as diagrammatically shown in Fig. 1 it may be assumed that fibers of cotton or the like are being conveyed by means of an air blast through an inlet or feeding portion A of a suitable transfer passage, which is also provided with a delivery portion or cotton receiver B- extending at an angle to the inlet portion. Mounted at the end ofthe inlet. portion of. the transfer passage is a centrifugal transfer and cleaning member C mounted facing the inlet passage A and arranged to receive fibers approaching the member C' in an axial direction butbeing adapted to deliver them peripherally through the outlet passage or receiver B. The member C comprising a spiral grill wheel and collector may be mounted in any suitable frame member but it will be understood that the wall portion in rear of the member C is preferably open to permit air from the inlet portion A of the transfer passage to pass therethrough, carrying with it trash which is passed axially through the centrifugal transfer and cleaning member C.
As shown in Figs. 2, 3 and 4, the centrifugal transfer and cleaning member C comprises a plurality of spiral spokes l secured at the center to a suitable shaft H and curving outwardly therefrom. The curvature may be that of an involute curve. Successive spokes may be connected to the adjacent spokes near their peripheries by suitable connecting means 12 which lend a certain degree of rigidity to the structure. A conical cap I3 may be provided at the front of the device, being preferably secured to the shaft II. The shaft ll maybe driven by any suitable means in a direction to deliver the fibers peripherally through the delivery passage or receiver B. Dirt and trash pass through the member C between the spiral spokes thereof and are discharged in the direction of the original air blast, as indicated at D. The spirally spoked transfer member C acts as a blower and creates an air blast in the direction of the outlet passage or receiver B which assists in the delivery of the fibers .through such passage, and corresponds generally with the member 28 of my prior Patent No. 2,484,524.
It will be apparent that the feed or inlet portion A of the transfer passage may be provided with any suitable cleaning or separating means as disclosed, for example, in my prior application Serial No. 598,043, and Patent No. 2,484,524, and that a fiber picker unit maybe provided adjacent the inlet of such passage as disclosed in the aforesaid application. It will be further apparent that the air blast which serves to transfer the cotton fibers through the passage A may also serve to direct cotton bolls on growing plants against rotary picker units in accordance with the disclosure of my aforesaid application and patent. The delivery or outlet passage B may, if desired, be connected with suction means which assists in the transfer of fibers through such passage, as described in said application and patent, but the use of such additional means has been found to be unnecessary since the centrifugal member C functions'as a blower. While the centrifugal transfer and delivery member C is particularly adapted for use in connection with the system disclosed in my application Serial No. 598,043, and Patent No. 2,484,524, it will be apparent that it may also be used in other connections as, for example, in the delivery of cotton fibers to a cotton gin or the like where it may be desirable to change the direction of movement of the fibers and also to remove, so far as possible, the dirt and trash which may have accumulated in the cotton which is to be delivered to the gin.
In Figs. 5 and 6 the invention is disclosed in connection with a cotton picker similar to that set forth in my application Serial No. 598,043 and in my Patent No. 2,484,524, dated October 11, 1949, except that in the present instance the picking units are set to rotate in the opposite direction from that in which the saws rotate in the aforesaid application and patent, while in Fig. 7 the invention is shown illustrated n.
4 connection with a rotating mesh picker of the type disclosed in my earlier Patent No. 1,961,447, dated June 5, 1934.
Referring particularly to Fig. 5 the fiber transfer and cleaning mechanism, including the feed and receiving passages A and B and the centrifugal transfer and cleaning member C, form part of a cotton picker carried by a vehicle adapted to move in the direction of the arrow E through a field of cotton. The vehicle is only diagrammatically illustrated and as shown is provided with a pair of forwardly projecting guide members l5 which serve to direct the plants of a row of cotton into a plant picking passage l6 where cotton bolls carried by said plants are adapted to be forcibly directed by means of a powerful air blast emerging through nozzle out let I! across the plant passage [6, against a rotary picking unit l8 located adjacent the inlet end of the cotton transfer passage in the form of spaced saws separated by guide disks of larger diameter than the saws, which picking units may be of the type disclosed in my Patent No. 2,484,524, except that in accordance with the present disclosure the picker unit is rotated in a direction opposite to that disclosed in the said patent. This arrangement has been found to be particularly desirable in that by causing the picker unit to rotate in a direction opposite to the direction of movement of the vehicle the cotton bolls themselves are not damaged and only the lint is removed, whereby much cleaner cotton is obtained than was heretofore possible.
The air blast from the nozzle l1 passes through the picker unit It and causes the lint together with some trash to pass through the inlet portion A of the transfer passage, in which portion are mounted suitable transfer and cleaning elements such as are set forth and claimed in my application Serial No. 598,043. These include a preliminary cleaning unit l9 having relatively widely spaced horizontally mounted saws and a second transfer and cleaning unit 28 having a larger number of more closely spaced toothed disks or saws. At the bottom of the inlet portion A of the transfer passage there may be provided sets of upwardly and forwardly inclined fingers 2| and 22 which allow trash to pass therethrough and fall through the open bottom of the passage but serve to direct the lint upwardly against the .teeth of the rotary units 19 and 28 under the influence of the powerful air blast passing through the transfer passage. The second transfer member 20 is arranged to direct lint against the centrifugal transfer and cleaning unit C substantially centrally thereof, which unit C serves to change the direction of movement of the lint and pass the same through the outlet or fiber receiving portion B of the transfer passage while. permitting .most of the remaining trash to pass out at D along with the major por tion of the air blast.
A similar arrangement is diagrammatically illustrated in Fig. '7, in which a reticulated picker unit I8 similar to the picker unit disclosed in my Patent No. 1,961,447 is substituted for the saw unit I8 of Figs. 5 and 6. In this arrangement the picker unit is likewise driven in a direction reverse to the direction of movement .of the vehicle upon which the device isfmounted. The reticulated picker [8 may, if desired, be provided with small teeth or hooks to aid in the removal of the lint, such hooks being preferably rearwardly directed similarly to the saw teeth of picker unit l8 shown in Figs. 5 and 6. In the anemia modification shdwn inFig'. '7 the transfer passage A is, onlypartially shown, it being: understood that the remaining portion may be the same as that. disclosedin Figs; 5 and 6' with the inclusion of the centrifugal cleaning and transfer unit 0 .at the end of such passage arranged to deliver the fiber to a cotton receiving portion B.
The reverse rotation of the picker units [8 and I8 per se is not my invention but is the invention of Alexander R. Nisbet, Jr., as set forth in his application Serial No. 215,763, filed March 15, 1951, entitled. Cotton Picking Machine.
The invention has been described in detail for the purpose of illustration butit will be obvious that numerous modifications and variations may be resorted to without departing from the spirit of the invention.
It will be understood that any desired type of receiver may be employed in connection with this apparatus, and if desired auxiliary means may beprovided, either pneumatic. or mechanical as desired, to assistin the delivery of the fiber to the final receiver.
