*GINNING.

Specification of Letters Patent.

Patented Aug. 28, 1911?.

Application filed September 8, 1914. Serial No. 860,806.

To all whom it may concern:

Be it known that I, l/VIIJJAM D. MCCOY, a citizen of the United States of America, and residing at Brooklyn, in the county of Kings and State of New York, have invent- I ed new and useful Improvements in Ginning, of which the following is a specification.

My invention relates particularly to improvements in methods and apparatus for the ginning of cotton.

The main object is to provide a method and apparatus for the separation of the seed from. the fiber with great rapidity and without injury to the fiber, and at a minimum of expense. One object is to avoid the use of complicated or expensive machinery. Another object is to utilize a method which will require a minimum of space for the apparatus. Another object is to provide a method which is suitable for the ginning of either long or short fiber cotton.

In the drawings I have illustrated one form of apparatus for'carrying out my invention. The invention, viewed from dillerent standpoints, contemplates the interaction of various forces and mechanisms and these may be combined in various ways, and

sure and the fibers pass out between the ribsc The ribs are then closed or brought into contact relation, at which time the seeds are removed by a stripping action of interior blades." The ribs are then opened allowing the fibers to be drawn out by an air current into the outer chamber through which they pass from the machine. The seeds fall down into a hopper and are wlthdrawn from the bottom of the machine. The stripping action is in-the direction of the joints between the ribs which may be termed a longitudinal action as distinguished from the ginning cylinder.

an action otherwise transverse to the joints between the ribs.

The ribbed wall of the inner chamber is preferably in two sections and the ribs of one section are opened while the others are closed. This provides openings from the iiiner chamber at all times, and thus prevents stagnation and increases the speed of o eration. The action of the stripping bla es in one section is continuous in one direction while the ribs are closed, and as the blades are arranged in a set all around the interior of the ribs and the action is rotary, there is no possibility of the seed or fiber being clogged as there would be if the action were continued in the same direction during the period of openness between the ribs. The mass of cotton and seed within the interior chamber is kept in constant motion by a series of paddlelike devices which assist in separating the difl'erent fibers. The wall of the inner chamber may properly be termed By having the ribs run continuousl around this cylinder they support each ot er and thus the adjoining ribs overcome any tendency to lateral flexure of the individual ribs, inasmuch as the ripping relation is continuous throughout the entire circumference. This also r0 vides a very extensive gripping area in a single cylinder so that even in a machine of very moderate dimensions a very extensive gripping area is provided. The process affords a practically continuous circulation of the entire mass of seed cotton. This not only prevents clogging of the machine, but insures great rapidity of operation. Air may be introduced into the bottom of the ginning cylinder to prevent fiber from fallingout with the seed.

I consider this process of drawing the seed-cotton intothe interior chamber, and drawing the fibers out into the outer chamber through the intermittent gripping of the ribs of the inner chamber to be of very great importance. The construction is such that the fibercannot escape from the machine until it is freed from the seed.

Figure 1 is a side view of the machine embodying the improvement of my inven tion.

Fig. 9 is a view in partial section on the central plane of Fig. 1 taken at right angles to the position shown in Fig. 1.

Fig. 3 is a plan and horizontal sectional view showing the interior construction and arrangement for oscillating the strippers.

Fig. 4 is an enlarged detailed sectional view of the gripping ribs and their connections.

Fig. 5 is a view on a similar scale of fragments of ribs showing part of their connections, the view being at right angles to that of Fig. 4.

Fig. 6 shows two views of part of one of the stripping members.

The seed cotton, or mixture of fiber and seed, enters the machine through the inlet 10 and the separated fiber leaves the machine through the exit 11. The separated seed passes to the bottom and is removed through the exit 12. The machine may be connected with the ordinary blower or flue system commonly used in a modern ginnery for the purpose of moving the seed cotton and fiber.

The wall of the ginning cylinder is formed of a plurality of ribs 13, either helical or merely annular in form, which extend around the shaft 14. A single strip formed into a helix making several turns around the axis serves as a readily supported and expandible member with openings between the convolutions adapted to be closed by pressure. Each convolution in effect constitutes an annular ring. In the form shown, the ribs-are arranged in two sets and the lower is supported by the ring 15. The upper rib of the lower set is held in place by the member 16, the perimeter of which is also in the form of a ring, and adapted to be moved up and down with the shaft 14. The upper set of ribs is supported by this member 16, and the upper rib of the upper set is held in place by the stationary ring 17. In the form shown the ribs are provided with spring members. 18 (see Fig. 4) which tend to separate the adjacent ribs. The adjacent ribs may also be connected by ties 19 and 20 to limit their separating movement. Preferably each rib; is provided with a facing of a suitable gripping material such as leather or wood so as not to injure the fibers which are gripped between the ribs. In the position shown in Fig. 2 the member 16 is holding the ribs of the lower set closed together in their gripping position while the ribs of the upper set are separated leaving openings between them for the fibers to pass through. By lifting the shaft 14 and the member 16 the upper ribs are closed together while the lower ribs are allowed to separate. One set of ribs may be formed by a helix and the other set by separate annular rings.

Inside the ginning cylinder is arranged a series ,of stripping members 25 for each set of ribs. These stripping members extend vertically in the cylinder and trans-v move the strippers in a direction longitudinal of the openings between the ribs. The upper frame 26 has a hub 27 mounted the sleeves 28 on the shaft 14..

Power is furnished to the machine through the medium of the fast and loose pulleys 30 on the shaft 31'. A bell crank lever 32 has one arm engaging the cam 33 on the shaft 31 and the other arm connect ed to the upper end of the shaft 14 so tha'-- as the shaft 31 is rotated the shaft 14 oscillated or reciprocated up and down and alternately raises and lowers the member 16. A vertical shaft 35 is driven from the shaft 31 by means of gears 36. The upper frame 26 carrying the upper series of strippers 25 is oscillated by means of a rod 37 connected to the crank v38 on the shaft 35 so that as the shaft 35 rotates the frame 26 1s oscillated or reciprocated back and forth. The lower frame 26 is oscillated in a similar manner by the crank 38 and rod 37. By reason of the two cranks 38 and 38 being at right angles to each other, the upper and lower series of strippers oscillate in opposite directions and their movement is timed to correspond withthe opening and closing of the ribs.

I also prefer to provide a fan having one or more vanes, such as 40, carried by' the sleeve 28 rotated continuously, for instance, by means of the rope drive 41 ,passing around the pulleys 42, 43 and 44. This fan serves as a distributer and opener for the seed fiber facilitating the action of the air currents in drawing the fibers out between the gripping ribs. The fan tends to throw the seed fiber out against the strippers and the inner wall v.of the ginning cylinder between the strippers and thus performs a function somewhat similar to that of a heater which is commonly an entirely separate machine and operation. The fan also generates air pres-' sure and assists in moving the seed cotton and fiberthrough the machine. A spring such as 46 may be provided for yieldingly holding the shaft 14 in position and thus compensate or balance the weight of the shaft and the parts supported by it: Springs such as 47 and 48 may be provided and held under compression between collars 47 and 48 rigid with the shaft 14, thus firmly yet yieldingly holding the annular member 16. This avoids shock' in the operation of closing the gripping ribs and prevents damage to the parts in case of the entry of any foreign substance beaces-as uniform alinement and operation of the parts.

The outer chamber for the fiber surrounds the outer wall of the inner chamber and lies between the ribs and the casing 50. The

'facilitate the distribution and passage of the seeds and the separation of the fibers.

A certain amount of air may be forced in or simply allowed to leak into the-bottom of the inner chamber through the passage 12, and up through the seed outlets 52, so

that if any fiber tends to pass out through the outlets 52 the air will draw the light fiber upward into thee-ginning cylinder and cause it to pass. outwardly from between the ribs. Partially ginned seed may be ocassionally borne down on to the plate 51 i by the .mass of falling seed incident to an' excess of seed cotton being fed to the machine. ,Such seed upon reaching the restricted seed discharge passage 52, are met by a strong air current by which they are freed. from the ginned seed and returned to the ginning members. The outlet 12 may be provided with a gate 12' for varying and controlling the inflow of air at the bottom of the machine.

One form of stripper is shown in Fig. 6. The relatively broad face 53 is preferably provided with serrated teeth 54 for better coiiperating with the seed and the fiber and insuring the separating of the seed with the minimum of injury to the fiber. It will be noted that by reason of the construction and arrangement of arts the strippers act as a skeleton hub or rame to assist in holding the ribs in their proper position.

The operation is substantially as follows The seed cotton, or mixed fiber and seed, are introduced at the top and circulated by the fan-vanes 40 at the top of the ginning cylinder. Some of the fibers immediately pass through between the open ribs of the upper or lower set of ribs dependingupon which set is o en. The rotation of the shaft 31 very quick y reciprocates or oscillates the shaft 14, and closes the open ribs and opens the closed ribs. As soon as the previously opened ribs have been closed the strippers which coiipera-te therewith are reciprocated or oscillated and the seeds knocked off. At the same time the air is drawing the fibers through the openings between the other ribs and the operation is repeated for each rotation of the shaft 31. It will thus be seen that there is alwa s one set of ribs open for the passage 0 fiber and another set of ribs closed in the stripping action, the two sets of ribs alternating in their respective functions. The fiber and seed are thus separated in what is practically a continuous operation, the cotton being drawn or'forced by air pressure through the outer chamber and the flue 11 and the seed passing through the openings 52 and out from the exit 12 to a Suitable receptacle. The seed cotton has practically instant and direct access to all parts of the ginning cylinder. By maintain ing a substantially constant suction or air pressurewith this apparatus I am enabled to get a uniform ginning action throughout the entire area of the cylinder. The advantage of this apparatus and method of ginning have been indicated herein, and will be apparent to those skilled in this art.

It will be noted the ribs when pressed together in gripping relation reinforce each other, each rib being in contact at both sides with the adjoining ribs. This insures a uniform gripping action throughout the entire area of the gripping cylinder. I wish it understood that the terms employed in the claims are of description rather than of limitation.
