- the spikes 22 of the cleaning-drum pick the cotton apart and thresh it against the screen 23, thereby effectually driving out the dirt and foreign matter lodged in it, which pass through the screen into the chamber 24, being drawn therein by the current of air established by the communication of said chamber 24 with the suction-flue 10, through the passage 25.
- valves 12, 13, and 26 are extended across the whole width of the chambers to which they give admission, and by adjusting the inlet area afiorded by their open position the results referred to may be accomplished.
- valve 26 For example, by opening the valve 26 a short distance only, according to the force of the suction in the flue 10 and the area of the screen 3, the air passing out of chamber 24 will be compelled to seek exit throughout the whole extent of the opening afforded by the valve and the air is compelled to traverse the ends of the chamber through which it passes with as much force as in the middle portion.
- This function of the valve 26 is supplemented by a suitable adjustment of the valve 139. the other end of the passage 25.
- By adjusting the valve 12 also with reference to the volume of air allowed by the valves 26 and 13 it is possible to use a screen 3 of less area than is otherwise practical.

- Fig. 5 of the accompanying drawings I have given a diagrammatic illustration of the complete apparatus by showing a working plant in operation. It will be observed that the fan 68, which exhausts air from the conveyer and elevating-pipe,is placed behind the gin and upon the same floor and connects with the suction-flue 10 by an air-conduit 69, which enters one side of the flue.
- the latter has communication with a plurality of exhaust-chambers, there being one complete mechanism similar to that shown in Figs. 1, 2, and 3 for each gin.

ROBERT S. MUNGER, OF BIRMINGHAM, ALABAMA.
COTTON ELEVATOR, CLEANER, AND FEEDER.
SPECIFICATION forming part of Letters Patent No. 680,165, dated August 6, 1901.
Application filed February 3, 1899. Renewed September 10, 1900, Serial No. 29,587. (No model.)
To all whom it may concern: 1
Be it known that 1, ROBERT S.'MUNGER, a citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented new and useful Improvements in Cotton Elevators, Cleaners, and Feeders, of which the following is a specification.
It is the purpose of my invention to provide mechanism for elevating, conveying, and
dental to a pneumatic conveyer or elevator may be much more thoroughly and perfectly accomplished, while the cotton is materially improved in quality and the period of useful service of the ginning devices is prolonged sufficiently to effect a marked economy as one of the advantages of my invention, these results being increased by the saving in time due to themore rapid action of which the gins are capable, when the grit and other foreign matters liable to clog, break, and rapidly wear away the gin-saws are practically eliminated.
It is my further purpose to so organize an elevator, conveyer, and cleaner for seed-cotton that the latter may be fed therefrom directly to the gins without the intervention of a distributer.
My invention also comprises other novel and useful features, all of which will be fully described hereinafter and then particularly pointed out and defined in the claims at the close of this specification.
For the purposes of said description reference is had to the accompanying drawings, in which- Figure 1 is a vertical section through the exhaust-chamber, feed-chamber, and clean ing-throat of an apparatus constructed in accordance with my invention, the section being taken upon the line 1 1 in Fig. 2. Fig. 2
is a front elevation of the parts shown in Fig. 1. Fig. 3 is a side elevation of the same, the point of view being at the right hand of the apparatus in Fig. 2, part of the lower portion being in section,'with the top of a gin indicated by dotted lines beneath. Fig. 4 is a detail perspective View of a part removed from the mechanism. Fig. 5 is a diagrammatic elevation showing a ginning house equipped with my invention, the Walls of the structure being broken away to disclose the interior. v
I In the following description I will first explain the construction, arrangement, and operation of the elevating, conveying, feeding, and cleaning apparatus and will then point out the arrangement and relations of the same to the ginning mechanisms.
The reference-numeral 1 in said drawings indicates a pneumatic conveyor, through which cotton is carried by an eXhaust-blastthat is to say, a blast orcurrent of air which is produced by exhausting or withdrawing the air from said conveyor at one end or point and admitting air from the exterior at another point, the cotton being carried by the air-current last referred to. The conveyer 1 extends or passes over the top of an exhaust-chamber, the latter being separated into two parts 2 and 2 by a vertical foraminous partition or wire screen 3. The chamber 2 opens directly into a feed-chamber at, in which is arranged a feeding roll or drum 5, having flexible or elastic wings 6 projecting in radial lines from the periphery of said drum. The edges of these wings pass, when the drum revolves, close to or in contact with a curved partition or wall 7, concentric with the drum 5. This partition forms part of the inclosing structure of an air-flue or air-chamber 8, which has communication with a chamber 9, forming one of the two chambers into which the exhaust-chamber 2 is divided by the wire screen 3. The chamber 8 also communicates with an exhaust-passage or suction-flue'lO by means ofa port which is controlled by a valve 12, (shown in Fig. 1,) the valve-shaft 13 being operated by a lever 14:,having a thumb-screw 15 mount- ,ed thereon. The end of the screw engages 'with a curved slot 16 in a plate 17, so that by turning it the valve-shaft can be locked with the valve in any desired position.
. communicates.
1 leads to the exhaust-conduit or suction-flue The valve-wings 6 are usually made either wholly or in part of rubber, so that they are elastic, and have a close fit upon the wall or curved partition 7 to prevent the passage of air between said partition and the drum 5.
The feed-drum 5 is so arranged that a passage 18 is formed between said drum and a curved breast or wall 19, which is practically a continuation of the front wall of the exhaust-chamber 2, with which said passage 18 The breast or wall 19 curves slightly downward and rearward or toward the drum 5, so that a gradual contraction is produced in the width of the passage 18, as shown in Fig.' 1. The passage terminates at a; point 20 just below the drum 5, or thereabout, this being its narrowest point or throat. Immediately below this throat is placed a drum 21, having cleaner and picker spikes or teeth 22 projecting from its cylindrical face and of such length that their ends or points revolve in closeproximity to the throat 20 and quite near the lower edge of the curved wall 19 and the edges of the valve-wings 6 on the lower side of the drum 5.
Behind and beneath the drum 21 is a screen or foraminous partition 23, which extends from the lower edge of the curved wall 7 and inclines in a plane which is nearly tangential to the ends of the spikes upon the rearward side of the drum and thence curves conce ntrically beneath the said drum, with a narrow space between it and the ends of the spikes 22. In the rear of the screen 23 and beneath it is a chamber 24, from which a passage 25 10. Said passage is provided with" a valve at each of its ends having any suitable form that will admit of an independent adjustment of said valves. stance, the inlet-valve 26 is hinged to one wall of the chamber 2-1 and maybe regulated by a rod 27, having one end hooked into a staple or eye upon the valve, while the other end projects through a Wall of the chamber and is threaded to receive a thumb-nut 28, by turning which in one direction the valve is opened, while by turning it in the opposite direction the valveis permitted to close. The other or outlet valve 13" at the exit end of the passage 25 is similar in construction to the valve 12. Upon one end of the valveshaft 29, which projects outside the wall inclosing said passage, is mounted a lever-plate 30, as seen in Fig. 3, by which the valveshaft can be turned to give any required adjustment of the valve 13 A screw 31 passes through a curved slot 32 in the lever-plate and enters the outer face of the wall, a thumbnut 33 being turned upon the threaded and shouldered outerend of the screw to lock the lever-plate at any point to which it may be turned.
I It will aid in arriving at a clear understanding of the invention if I describe at this point the functions of the parts thus far mentioned and their method of operation when com- As shown in this inbined and arranged in the manner shown. It will be understood that the conveyer 1 is so arranged as to take cotton from any point, and in this instance I have shown it in Fig. 5 in the act of taking cotton from a wagon 34 by means of a telescoping drop-pipe 35, which enters or has communication with the conveyer. This pipe is jointed and is flexible and constitutes in the present illustration of the invention the means for elevating the cotton. It needs no specific description, being shown, described, and claimed in Letters Patent No. 308,790, issued to me December 2, 1884. The drop-pipe is connected to the conveyor 1 by a curved section 1, and that portionof the conveyer which connects directly to the elevator enters or communicates withthe portion 1, lying at a right angle, by means of a similar curved section,whereby the direction of movement is changed gradually.
It should be noted that these constructional features are all subject to a wide variation without any departure from my invention.
As a simple example of such modification I will mention that the cotton-conveyors may enter the front of the exhaust-chamber 2 instead of the top, and when two or more are I erable.
connected such a construction will be pref- Any' other point of entrance which will permit of the contemplated operation may be used also as well as those specified.
IA second elbow is also employed communieating with a conveyor leading from a cottonhouse where the raw fiber is stored, as shown -in my Letters Patent already mentioned.
The mechanism for producing the necessary exhaustion of air will be referred to hereinafter, it being sufficient for the present to understand that there is a partial exhaustion of air established in the suction-fine 10, the
. valves 12, 13 and 26 being suitably adjusted to give the necessary com munication between the flue 10, the exhaust-chamber 2, and the chamber 24.
The feed-drum 5 is given a revolution from right to left at a slow speed, as shown by the arrow in Fig. 1, and the cleaning-drum 21 is I shown in the present instance as if it were :rotated in the opposite direct-ion with a comparatively high speed, this direction of moveinent being-shown by an arrow in Fig. 1.
It is not indispensable, however, that this direc- 1 tion of construction be followed, since I may drive the cleaning drum in either direction without affecting the operation of the other parts or the result arrived at.
The cotton which is drawn into the mouth of the jointed Etelescoping elevator or drop-pipe is carried up therein, passes into the conveyer 1, and
thence into the exhaust-chamber 2.
The
so far as they are removed, pass through the screen 3 and into the chamber 2- behind it,
building, as explained hereinafter.
The exhaust-chamber 2 is preferably arranged so that the cotton coming into it from the conveyer 1 will pass by its own gravity to the feed-chamber 4 and into the broad mouth of the passage l8,where it is subjected to the action of the feeding-drum 5. This drum having a comparatively slow rotation, its speed being perhaps one complete revolution per minute, or thereabout, takes the cotton in the upper part of the feed-chamber and by its fluted or corrugated surface and projecting wings, which turn over toward the wall 19 and downward, it rolls the cotton, and as it travels down in the passage 18 it is slowly compressed into a mass of constantly increasing density owing to the gradual contraction of the passage. In this manner a closely-compacted body of cotton is maintained in the throat 20 and above the same, by which any material leakage of air is prevented, leakage on the other side of the feeddrum being cutoff by the wings 6 and the curved partition 7. Upon passing the throat 20 the bat of cotton is subjected to the action of the spiked cleaning-drum 21, which is driven at high speed in a direction from left to right, or vice versa. Thus whether its rotary movement is opposite that of the drum 5 or in the same direction the spikes 22 upon its upper side act upon the compacted mass of cotton near the lower or adjacent side of the feed-drum, so that they practically assist the onward movement of the cotton in the throat 20 and its uniform removal from that point to make room for the constantly-advancing mass behind. It accomplishes this result without such action as would tend to produce a leakage of air through the throat 20. In one direction of revolution the cotton will be simply disintegrated from the compressed bat lying in the throat 20 and carried over the screen 23, as shown in Fig. 1. When the feed-drum is rotated in the opposite direction, the cotton will simply be thrown into the chamber 36 and go to the gin without passing over the screen 23. The spikes 22 of the cleaning-drum pick the cotton apart and thresh it against the screen 23, thereby effectually driving out the dirt and foreign matter lodged in it, which pass through the screen into the chamber 24, being drawn therein by the current of air established by the communication of said chamber 24 with the suction-flue 10, through the passage 25.
In order that there may be a substantially uniform action of the air-current upon every part of the screen or as nearly so as possible and to permit such a regulation of the aircurrent drawn through the screens 3 and 23 as may be necessary relatively to the air pass- ,ing the screen 23, the valves 12, 13, and 26 are extended across the whole width of the chambers to which they give admission, and by adjusting the inlet area afiorded by their open position the results referred to may be accomplished. For example, by opening the valve 26 a short distance only, according to the force of the suction in the flue 10 and the area of the screen 3, the air passing out of chamber 24 will be compelled to seek exit throughout the whole extent of the opening afforded by the valve and the air is compelled to traverse the ends of the chamber through which it passes with as much force as in the middle portion. This function of the valve 26 is supplemented by a suitable adjustment of the valve 139. the other end of the passage 25. By adjusting the valve 12 also with reference to the volume of air allowed by the valves 26 and 13 it is possible to use a screen 3 of less area than is otherwise practical. Moreover, by closing the valve 12 the whole force of the current may be thrown upon the screen 23 and the cotton in the feed-chamber 18 and throat 20. After passing off the screen 23 the cleansed cotton goes into a passage 36, by which it is delivered directly to the ginning apparatus, the latter being indicated in dot ted lines in Fig. 3.
The shaft of the cleaning-drum 21 is provided with a loose pulley 37, (shown in Figs. 2 and 3,) which is belted to a pulley 38 on the shaft carrying the gin-saws. A clutch-box 39 is keyed upon the drum-shaft, Fig. 2, and adapted to engage with and bedisengaged from a clutch-section on the hub of the pulley 37. A lever 40, fulcrumed upon a bracket 41, serves to operate the clutch-box and bring the cleansing-drum into and out of operation. The shaft of said cleaning-drum also has a friction-disk 42, which is adapted to drive a second friction-disk 43, the latter of which also carries a spur-gear 44, the gear 44 having mesh with a larger gear 44, supported by a stud on the frame. A pitman 45, having one end engaged with a wrist upon the gear 44, has its other end adjustably connected to the slotted end of a pivoted lever 46. Upon each side of the pivotal bearing for the latter a push-rod 47 is connected, a pawl upon its free end enga ing a ratchet 48, having a pinion 49 upon its shaft. This pin ion meshes with a spur-gear 50 on the shaft of the feed-drum 5, revolving the latter with the proper direction and speed.
The friction-disk 43 is mounted upon a stud 51, projecting from a plate 52. A11 eye or loop 53 projects from the center of the plate and the stud 51 passes through it, said eye having a short bar 54 extending from it. The plate 52 is mounted upon a pivot which passes through a hole 55, Fig. 4, eccentric to the stud, and enters the wall of the machine-casing. A rod 56 passes through a slot 57 in the end of the bar 54 and has a spring 58 coiled upon it between the bar and a nut 59, adjustable upon the threaded cnd of the rod.. The
come to a stop.
tension of the spring 58 swings the plate 52 upon its pivot and pushes the frictiondisk 43 away from or in a direction to remove it from contact with the disk 42 when held in such contact by the operation of the rod 56. The spring 58 insures a yielding contact. Acollar 60, loose and adjustable upon'the rod 56 on the other side of the bar 54, engages the latter when the rod is moved longitudinally against the tension of the spring 58, swings the plate 52 in the opposite direction,and separates the friction-disks, causing the feeding-drum 5 to The rod 56 extends to the front of the machine and has a knob or handle 61 and is provided with a series of teeth 62 to engage a detent 63, so that the frictiondisk 43 may, if desired, be held fora time out of engagement with the friction-disk'4c2. By these means the operation of the feed-drum 5 may be arrested at any moment and caused to remain inoperative, according to the requirements of the gin. The cleaning-drum will be independently controlled by the clutch-operating lever 40.
The breast-wall 19, which forms one side of the passage 18, is not only removable, but is made adjustable in such manner as to regulate the width of the passage 18 and of the opening or throat 20. For this purpose the wall is pivoted at its upper edge and is provided with leaf-springs 64, the tension of the latter being increased or diminished by means of cams 65, mounted on a cam-shaft 66,which is turned in its bearings by levers 67, projecting from the ends of the shaft, as shown in Figs. 1, 2, and 3.
In Fig. 5 of the accompanying drawings I have given a diagrammatic illustration of the complete apparatus by showing a working plant in operation. It will be observed that the fan 68, which exhausts air from the conveyer and elevating-pipe,is placed behind the gin and upon the same floor and connects with the suction-flue 10 by an air-conduit 69, which enters one side of the flue. The latter, as will readily be understood, has communication with a plurality of exhaust-chambers, there being one complete mechanism similar to that shown in Figs. 1, 2, and 3 for each gin. As each mechanism is practically independent of all the others, I dispense with all devices between the same and the gin and deliver the clean seed-cotton to the latter apparatus directly from the cleaningdrum. The air-exhausting fan may of course be located elsewhere and at any convenient point, provided that the suction-flue 10 communicates with the chamber 2 behind the screen 3 and with the dust-chamber 24 by independent air-passages, the passage leading out of the latter chamber being preferably caused to take the air therefrom at a point beneath the cleaning-drum 21, or nearly so. The air-exit from the fan-casing 68 enters or communicates witha chimney 71, by which the dust, dirt, leaf-trash, and other foreign matters removed from the cotton are blown out of the gin-house andpass off without any portion of the same being driven into the ginning-room to affect the health of the operatives and become deposited upon the cotton. The conveyerl, as shown in Fig. 5, is carried along at a point where it can have suitable communication with the exhaust chamber 2 of each machine. 7
To show a complete plant, I have included inFig. 5 the seed-handling mechanism,which,- however, forms no part of my present invention. The reference-numeral 72 indicates the seed-hopper, and 73 the blast-flue or air-box, which receives the seed from a due beneath the hoppers 72 and carries it to any point desired as, for example, a wagon 74, outside the building. The air-box 7 3 receives a forced blast of air through a conduit'75, which receives airfrom the exit-passage 70, that leads from the casing of the fan 68 to the chimney 71. This arrangement will necessarily result in driving off more or less of the dust, leaftrash, and other refuse withdrawn from the chamber 24 through the fan-casing 68 and thence through the exit passage 70 from said easing into the blast-flue 73. After traversing the latter it will be driven off through a chimney 76, which also carries off the dust which had become mingled with the seed, leaving the latter clean.
