T0 all whom t may concern.'

Be it known that I, JOHN 1/VOOLDRIDGE, a citizen of the United States, residing at Moody, in the county of McLennan and State of Texas, have invented a new and useful Cotton Gin, of which the following is a specification. y

This invention relates to cotton gins of the double type, wherein the seed treated is acted upon by two sets of saws.

One of the objects of the invention is to so construct a gin of this type that it will have a maximum speed and eiiiciency with a minimum use of power.

Another object is to provide a one man gin of this character which will produce a good grade of cotton, take oft more cotton from the seed, and operate with extreme rapidity.

Another object is to provide a cotton gin in which two sets of saws are employed and equipped with means operable to take the seed from the first set of saws when one half ginned and feed them to the second set for completion, thereby producing a very fine grade of lint cotton.

Another object is to provide a gin of this character with means for parting the liber and straightening it out on the gin saw before it passes out between the ribs, thereby preventing breakage of the staple.

Another object is to provide a gin of this character equipped with a knee rib so positioned as to direct the partially ginned seed in its passage between the saws to the lower breast of the gin.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described, and claimed it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention, can be made without departingfrom the spirit of the invention.

The accompanying drawing representsa transverse vertical section of the gin constructed in accordance with this invention.

In the embodiment illustrated, the upper roll box of the gin is shown at l under which is arranged the set of saws 2 ordinarily employed in machines of this character.

A knee rib 3 is arranged at the lower part of the box l opposite the inturned end 5 of the front board. The sharp point 4 of this rib operates to direct the seed which pass between the saws into the lower breast of the lower roll box 7. j

A delivery hopper 6 is employed in connection with box'l to assist knee rib 3 in directing the seed passing from said box.

The lower roll box 7 is of ordinary construction, being arranged below the roll box l in the usual manner and has located below it the usual gin saws 8.

A doiiing brush 9 is located at the rear of and adjacent to the two sets of saws 2 and 8 and operates to clean both saws 2 and 8 and to deliver the cotton through flue 13 from which it is conducted to a suitable place of deposit.

Another set of saws 10 is mounted to rotate on a shaft ll in box l and each carries a plurality of large teeth 12, four of which are here shown, and which are designed to pass between the saws of set 2 and operate to part the liber delivered by said saws and to straighten it out before it passes out between the ribs, thus preventing all possibility of breakage of the staple.

The gist of this invention is to remove the seeds from the first set of saws 2 when only half ginned, and pass them on to the set of saws 8 for completion, whereby a very fine grade of lint cotton is produced. This operation also effects the taking off of more cotton from the seed as well as to promote speed in ginning while consuming a minimum amount of power only. This is accomplished owing to the fact that the upper roll is run loosely so that the cotton is not held tight enough against the first set of saws a sufficient time to clean the seed and by the assistance of the knee rib 3 the cotton is carried t-o the second set of saws. The first set of saws Vinstead of cutting the cotton into bits as it would do if operated with a tight roll takes the cotton olf unbroken. Since the half ginned seed are taken out of the top roll box by the knee rib it leaves the top roll box with a soft roll of good long staple cotton which is sent to the press in perfect shape. The staple that is left on the seed is also unbroken and passes to the second set of saws for ginning. The second set of saws being comparatively clean of cotton the unginned seed reaching them is also ginned r`infine-shape. Y

Fromrithe above yf'o'les'oription fit will be iobvious'that Ya gin constructed as herein shown andfdeseribed may be manufactured ,at a veryeismall costaud ,it may be operated by one man.

'- I claim In a cotton gin, the combination With a roll rInox and saws, of #an auxiliary isetoi saws having large teeth operable between the saws irst mentioned, and adapted to part and straighten out fthe fiber :to prevent breakage of the staple.l Y A In testimony that I claim the foregoing as' my own, I havehereto affixed mysignature inthe presence of two Witnesses. v
