AIR GIN Filed June 9. 1956 av @ywl ATTORN EVS Patented Oct. 18, 1938 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to gins wherein pneumatic means and centrifugal force is employed to bring about separation of the motes and other foreign matter from the lint and the conveying of the latter to condensers. In gins of this character, the pneumatic means causes a vacuum to be developed which aiects the centrifugal force and interferes with the separation of the motes from the lint. The present invention has for the primary object the provision of pneumatic means for destroying the vacuum and thereby permit the centrifugal force to function to the maximum for bringing about a thorough separation of the motes from the lint and consequently permit lint to be obtained in a cleaner state.
With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a transverse sectional View illustrating my invention adapted to a gin.
Figure 2 is a fragmentary transverse sectional view drawn on an enlarged scale showing the pneumatic means for destroying the vacuum.
Figure 3 is a fragmentary sectional view taken on the line 3-3 of Figure 2.
Referring in detail to the drawing, the numeral I indicates a gin employing centrifugal force for the separation of motes and other foreign matter from the lint and also employing pneumatic means for collecting and conveying the lint from the saws 2 and delivering said lint to condensers (not shown). In gins of this character the velocity of the air employed for conveying the lint from the saws to the condensers is so great as to create a vacuum in the upper portion of the gin. This vacuum aifects the centrifugal force preventing the latter from thoroughly separating the motes and foreign matter from the lint. My invention when adapted to a gin of the character described will break up or destroy this vacuum and includes in its construction a duct 3 employed for conveying the lint from the saws to the condensers. The duct 3 is formed in a casing 4 easily adaptable to the Igin I and the air blast pipe 5 thereof. The casing terminates at the rear of the saws in the form of an elongated nozzle 6. One end of the duct 3 is spaced a considerable distance from the nozzle 6 so that the lint collected by the saws will be removed from the latter by the air blast from the air blast pipe 5 passing the saws into the'duct 3. A duct 1 is formed in the casing 4 and communicates at one end with the air blast pipe 5 and at the other end with the nozzle 6. The ducts 3 and I are separated from each other by a wall 8 and one end of the wall 8 terminates within the nozzle 6 and is spaced from avwall 9 of said nozzle to form an air outlet 9 to the nozzle for discharging air blasts against the saws and to the duct 3. This air travels at a high velocity and will develop a vacuum in the upper portion of the gin.
Secured to the nozzle 6 is a hood IB including a wall II. The free end of the wall II is spaced from the wall 9 providing an intermediate air outlet I2. Formed in the wall 9 is a series of ports I3 permitting some of the air passing through the duct 'I to escape into the chamber I4 formed between the hood Ill and the nozzle. Some of this air escapes by Way of the outlet I2 having the effect of partially destroying the Vacuum. The wall II of the hood has a series of ports I5 communicating with the chamber I4 so that some of the air from the chamber I4 may escape cooperating with the air from the intermediate outlet I2 in completely breaking up or destroying the vacuum. The air leaving the outlet I2 is in the form of a column. Also the air leaving the outlet 9 is in the form of a column. The column of air leaving the outlet 9 has a greater velocity than the air leaving the outlet I2. The air leaving the ports I5 are in the form of a series of columns of less velocity than the column of air leaving the outlet I2. The combined area of the outlets I2 and I5 is greater than the combined area of the ports I3 so that when the air passes from the outlets I2 and I5 the velocity of such air will be materially reduced. To further aid in reducing .the velocity of air leaving the outlets I2 and I5, the chamber I4 will permit an expansion of the air as it leaves the ports I3. Thus it will be seen that the same air pressure employed for conveying the lint from the saws to the condensers is also employed for creating columns of air to destroy vacuum set up by the column of air used in'conveying the lint to the condensers by way of the duct. 3.
A device of the character described is simple in construction and operation and may be readily adapted to a gin now in use and will permit the gin to more thoroughly perform its function of separating motes and foreign matter from the lint, consequently permitting lint to be obtained in a cleaner state.
