COTTON- GRADEB.

Specification of Letters Patent.

Application filedjune 7, 1909. Serial No. 500,624.

T 0 all whom it may concern:

lle it, known that l LEMI'AL A. GREENE, a citizen of the United States. residing at Grcenville, in the county of (ircenville and State of South Carolina, have invented certain new and useful Improvements in Cotton-Graders: and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will 011-. able others skilled in the art to which it appert aius to make and use the same.

M y invention relates to cotton graders ot' the type shown and described in U. S. Patent No. 499,358, issued on June 13, 189?). and No. 935,149 issued September 28, 1909,

wherein a variety of samples of cotton of known quality are arried in a case under a transparent cover which maybe extended beyond saidcase so that a sample of unknown quality may be placed below it and compared with those in the case.

The case disclosed in the-patents referred to is capable of conveniently carrying only a limited number of samples. If it is desired to have more samples, it would be necessary to lengthen the case which would tend to make it inconvenientto handle.

The principal objects of my present invention are to provide for carrying a large number of samples of determined grades; to make the device more compact; and to arrange the samples so that a quantity of cotton of unknown grade may simultaneously be compared with a large number of samles of predetermined grade.

. The invention consists primarily of a case containing a receptacle for receiving a sample of cotton of unknown grade, and a plurality of compartments arranged around the receptacle. A

The invention also consists of the generic and specific features of construction and arrangement of parts, substantially as hereinafter described and claimed.

In the accompanying drawing illustrating two embodiments of my invention, Figure 1 is a plan view of a cotton grader of rectangular {form constructed in accordance with my invention; Fig. 2 is a central longitudinal section of the grader shown in Fig.

1. and. Figs. 3 and 4 are similar views of a circular form of grader.

In Figs. 1 and 2 of the drawing, 1 desig- 4 if iised, conforms to the sha nates a case which is made rect-angular'in form and contains the compartments 2 arranged around an opening 3 which is pretcrably without a bottom. The compartments 2, each of which is intended to contain a sample of cotton of determined grade and of a grade different from that of the other compartments, and the opening 3 are preferably though not necessarily covered by a. transparent cover 4. which if desired may 'be of niagnifyingglass.

A transparent cover admits of samples in the case being viewed without opening the con'ipartmcnts. and also protects said Samples from dust or other foreign substances which would change their appearance if allowed to collect on them. Again, if it is desired to seal the *ases so that the samples contained therein cannot be removed or changed the transparent cover. may be permanently attached to the casing for this purpose.

The construction illustrated in Figs. 3 and l: involves a circular case 1 containing radial compartments 2 arranged around a circular opening 3. The transparentcover e of the case and preferably extends over t e opening 3 as well as over the various compartments.

Itis dilticult to determine the grade of a sample of cotton when the sample is to be compared with cotton of various predetermined grades which is subject to dilter'ent lights or conditions of light. Inasmuch as by my'device. the cotton of known grades and the sample to be tested are compactly held. they are all in the same light and therefore an accurate comparison is easily made. I

The greater facility and convenience in handling either of the forms of cotton Patented Mar. 22, Milt).

Having thus described my invention, Wbzfl; I claim as new, and desire to secure by Let tors Potent, is:-

1., A. cotton grader comprising; a case hovixig on ogenimg therein, arm? a series-oi comartments for containing samples of cotton surrounding the opening.

esases partments being :n'ymnged in close pr imit to the opening, hoth the case and open- 'mg eing covered by transparent material. 5. A. cotton grader compnsing av case hav ing a bottozmess opening therein, and u series of compartments for containing samples of cotton sumouning the opening.

6, A comm grader comprising a case having a bottomless opening therein, and a series of compartmem's for containing Sam ples of cotton surrounding the opening, both the opening and the compartments being covered. by transgmrentmaterial.

in testlmoiny whereof, I aifix my sign ture, in presence of two witnesses.
