COTTON ELEVATOR AND LDISTRIBIII'IEJRI.
Application filed April 6, 1912. Serial No. 688,876.
To all whom it may concern:
Be it known that we,JosnP1-r N. ELLEN- BURG and ALEXANDER NELSON, citizens of the United States, residing at McKinney, in the county of Collin and State of Texas, have invented certain new and useful lmprovement-s in Cotton Elevators and Distributors,
of which the followi-ng'is a specification.
Our invention relates to new and useful improvements in cotton elevators and dis tributers, and relates more particularly to such devices of this class as depend for the production of a vacuum.
The object of the invention is to provide a vacuum-operated cotton elevator and d1stributer so constructed'that the cotton will have no tendency to clog the screen through which air is withdrawn from the cotton conveying pipe.-
Another object of the invention isto pro vide an improved form of vacuum box, forming part of a combined elevator and distributor, a means being provided within said box "to accurately regulate the intensity discharged cotton from the outlet of the discharge pipe.
Finally, the object of the invention is to provide a device of the character described that will be strong, durable, simple and efficient, and comparatively easy to construct and also one, the various parts of which will not be likely to get out of working order.
With these and various other objects in view, our invention has relation to certain novel features of theconstruction and operation, an example of which is described in the following specification, and illustrated in the accompanying drawings, wherein:
Figure] is a view of the combined elevator and distributer in side elevation, the cotton inlet pipe and air exhaust pipe being both broken away and a conveyor casing being shown in dash lines, which may be substituted tor the swivel discharge pipe shown in full lines. Fig. 2 is a vertical, axial, sectional elevation of the same. Fig. 3 is .a

horizontal, sectional view taken upon the line of Fig. 2. Fig. 4c is a detail, perspective view showing a novel form of slide valve employed to control the passage of air from the exhaustchamber into the exhaust pipe.
Referring now more particularly to the drawings, wherein like reference characters designate similar parts'in all the figures, the numeral 1 denotes a frusto-conical exhaust chamber, preferably of sheet metal can st-ruction, the top of said-chamber having communication with a vertical inlet pipe 2, and the bottom thereof having communication with a vertical outlet pipe 3. The pipe 2 communicates through a suitable elbow with a horizontal pipe 4 oxteruling to and coimnunica'ting with some receptacle for cotton, as for example, a wagon box. The pipe 3 extends upwardly for some distance into the casing, as clearly shown in 2, and its upper extremity is connected with the lower extremity of the pipe 2 by a frustoconical wire screen 5. An air exhaust pipe, having a valve member 7, communicates with the lower extremity oi. the casing 1 at some point between the vacuum box 1 and the tan or similar device (not shown) by which suction is created. By opening the valve 7, the suction within the box 1 may be destroyed at any time, thus permitting any cotton in the discharge pipe to escape. A horizontal partition 8 divides the exhaust box into a large upper compartment A and a small lower compartment B, the upper end of the pipe 3 being passed through said partition and terminating just above the same. As is'elearly shown in'Fig. Q, the exhaust pipe 6 communicates with the compartment 13 of the exhaust box just below'the partition. The larger compartment A of the vacuum box is divided into three equal minor compartments by the same number of vertical partitions 9, said partitions extending between the inner surface of the casing 1 and the outer ot" the screen 5 and being perpendicular to both of said surfaces. Communication is established between the compartments A and B through twelve circular apertures 10, four of which communicate with each of said three minor compartments. A sliding valve formed by a metal. plate 11, and provided with two circular apertures 12, is adapted to o en or close two otthe apertures 10 throng a sliding adjustment. One extremity of said valve member is bent over, as indicated at 13, to form a handle by which the valve may be conveniently slid back and forth. Each of the sliding valve members 11 are guided during their sliding adjustment by a pair of curved metal strips 14, said strips transcribing fragmentary arcs having their centers upon the central axis of the casingl. The side wall of the casing 1 is provided with three equidistantapertures 15, each communicating with one of the minor compartments of the large compartment A. Each aperture 15 is adapted to be closed by a vertically sliding door 16,.havinga handle member 18 at its top and received by guiding strips 17 rigid with the casing at each side of the door. Normally the doors 16 oocupy positions closing the apertures 15.
The lower extremity of the discharge pipe 3 communicates withdan inclined pipe 19 through a swivel elbow. The lower extremity of the pipe 19 is at an elevation above the floor upon which cotton is to be discharged. A fabric sleeve 20 has its upper end mounted upon the lower end of the pipe '19, being held securely in such a ositi'on by means of a clamping ring 21. aid sleeve depends for some distance below the lower end of the pipe 19. The inclined pipe 19 is supported by a vertical rod 22 axial with the pipe 3, the lower end of said rod being received by a thrust bearing 23 resting upon the floor, and its upper end being received by an angular bracket 24 secured to the 7,
upper portion of said pipe 19. The lower end of the pipe 19 is further supported by a horizontal brace member 25, one end of which is mounted upon the rod 2 2 and the other end received by an angular bracket 26 secured to the lower extremity of the pipe 19.
The operation and advantageous features of the above-described invention will now be more fully discussed.
- In all types of cotton elevators now commonly used, considerable trouble and annoyance is occasioned by the tendency of the cotton to clog up the screen through which air is withdrawn from the vacuum box. In the" above-described invention this annoy- I ance is eliminated by providing a comparativel large screen area, through which the air is uniformly withdrawn at all sides. The strength of suction at any one point of the screen is thus sufiioiently reduced to prevent the cotton being deflected laterally from the natural path in which it falls through the vacuum box. The trusts-conical shape of the screen 5 is a very important conslderation in preventing the cot-ton from clogging the screen, since it spaces the screen from the falling cotton and thereby weakens. the effect of the suction in its tendencyto draw the cptton toward the screen.
*"at the foot of the rod 22.
It is also apparent that a ver uniform suction may be secured by divi ing the larger compartment A of the vacuum box into minor compartments with each of which several valve-controlled apertures communicate, through which apertures the air is Withdrawn. Obviously, such an arrangement makes it quite impossible for the suction to act at any one side of the screen 5.
It may further be observed that, since the suction acts through the screen 5 equally' from all sides, any tendency that may arise to move the-cotton laterally toward the" be sufficiently opened to permit the force of suction to be modified by a certain amount of air entering through said valve.
The novel feature of the discharge pipe 19 lies in its swivetconnection to the pipe 3, said discharge pipe being "pivotally supported by'the rod 22, may be swung about its swivel connection and made to assume various positions lying in acircle centered cotton accumulates sufiiciently on the floor to'block the outlet of the pipe 19, said pipe may be readily adjusted so that itmay (llS- charge upon a clear floor space, and this adjustment may be repeated a large number of times without making it necessaryto remove the discharged cotton.
In case it is desired to gin the cotton immediately after its discharge from the elevator, an ordinary conveyer casing 27 may be substituted for the discharge pipe 19, said eonveyer casingbeing made toconnect with a gin (not shown).
Thus when the It is obvious that various changes and 3 modifications may be made in the form and proportions of parts in the above-described invention without departing from the spirit or sacrificing the advantages thereof, and said invention is presented as including all such changes and modifications. as come.
within the scope of the following claims.
