VINFIELD O. GUNCKEL, OF TERRE HAUTE, INDIANA.

Speccaton of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 26,1906. Serial No. 308,109.

To all whom t may concern.-

Beit known that I, WINFIELD O. GUNCKEL, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have linvented certain new and useful Improvements in Coal-Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to mechanism for separating coal and other similar material into various grades-such as lump coal, nut coal, and pea coal and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the end portions of the separator. Fig. 2 is a plan view of the same. plan view showing a modification in the arrangement of the rolls in the separator and showing one of the said rolls in longitudinal section. Figs. 4 and 5 are respectively an end view and a longitudinal section of one of the spring distance-rings.

A is the frame of the separator.

B represents the separating-rolls. These rolls are journaled in the frame in a series parallel with each other.

The separator is preferably arranged in an inclined position, although shown in a hori- Zontal position in the drawings. The material is discharged onto one end portion A2 of the separator, which is its upper end. The rollers nearest this end A2 are spaced close together, so that there are very narrow openings between them, and the rolls at the other end portion of the separator are spaced farther apart, so that the material may be separated into different grades. Suitable means are provided for discharging the material onto the upper end portions of the separator and for receiving the different grades of separated material. These means are of any approved. construction and are not shown in the drawings.

Each roll B consists of a hollow cylindrical shell mounted on a shaft b or having shaft ends b projecting from it.

The rolls are all revolved continuously in the directions of the arrows in Fig. I, and they all revolve in the same direction.

C represents sprocket-wheels secured to the shaft ends t at one end of the rolls. Every alternate roll is provided with a sprocket-wheel C. D is a drive-chain which Fig. 3 is also a passes around all the sprocket-Wheels C and causes the rolls connected to them to revolve in the same direction. E represents guidebars which hold the intermediate portions of the upper bight of the drive-chain in engagement with the sprocket-wheels, so that the chain is prevented. from jumping or slipping. The guides may be single continuous bars, or they may be formed in sections, or any other approved guiding devices, such as uidesheaves, may be used. C represents similar sprocket-wheels secured to the shaft ends of the remaining rolls at the other ends of the rolls from the sprocket-wheels C. i

D is a drive-chain which passes over the sprocket-wheels C and drives them all in the same direction. The drive-chain D/ is provided with a guide-bar E, the same as the drive-chain D.

The sprocket-wheels are all considerably larger than the rolls which they drive, so that ample power is provided, and each sprocketwheel overlaps the shaft ends of the two adjacent rolls, the said rolls being spaced near together, so as to be effective in screening or separating coal. i

.The shaft on one of the rolls is provided with a driving wheel or pulley F, and G represents driving connections operatively connecting two of the rolls, so that all the rolls revolve in the same direction.

In the modil'ication shown in Fig. 3 the rolls are arranged the other way-about from the positions shown in Fig. 2 and so that the material is discharged onto the end portions of the rolls. In order to separate the coal into different grades, the centers of all the rolls are arranged at the same distance apart, and the rolls are made of different diameter at different parts of their length. Each roll B is provided with a shaft or shaft ends t', secured in any approved manner into a tube g'. Gr is an outer tube or shell at one end portion of the tube g, and h represents spring distance-rings between the two tubes. The spring distance-rings 7L are split upon one side, and they are tapered externally. The internal end portions of the outer tubes G are preferably slightly tapered also, so that when the spring distance-rings are driven forcibly into the spaces between the end portions of the tubes they are clamped to both tubes, and the tubes are held concentric with' each other. Rivets or pins 'i are driven through holes in the said tubes and rings, so as to secure them permanently in position.

ICO

Y What I'claim isl. In a separatorfthe combination, with a series of smooth cylindrical rolls arranged with narrow screening-spaces betweenthem,

of drivingwheels secured to the alternate rolls of thesaid series zand at one end of the said rolls, driving-wheels secured to the remaining rolls of the series and at the other ends of the said rolls, iieXible driving devices passing 'around each series of driving-wheels and arranged with their lower bights clear of the intermediate wh eels of each series, means forholiding the upper bights oi' the said drive ing 'devices in engagement with all the' driving-wheels, and means for revolving both series'of driving-wheels in the same direction.

2. In afseparator, the combination7 with a series I of vsmooth vcylindrical rolls :arranged withn'arrow screening-spaces between them, of sprocket-wheels secured tO the alternate rolls f the said series and at one end of the saidrollsjsprocket-wheels secured to the' remaining rolls 'of the series and at the other end `of the said rolls, drive-chains passing around eachV series of sprocket-wheels and arranged with their lower bights clear of the in termediatewheels of each series, means for holding the upper bights of the 'said drivechains in engagement with all the sprocketwheels', and means for revolving both series of sprocket-wheels in the'same direction.

3. In a separator, the combination,- with two series of smooth cylindrical rolls, the rolls of oneseries being arranged alternately of the rolls of the other series, and driving-wheels secured to the rolls of one series and arranged at one end of the said rolls, driving-wheels secured to the rolls of the other series and ar- `.ranged at the other end of the said rolls, al1

'driving-wheels, and driving devices which connect two of the said rolls Vso that all the rolls are constrained to revolveI in the same direction.

4. In a separator, the combination, with a supporting-frame, a driving mechanism; of

a series of sep arator-rolls journaled inthe said frame, and provided withmain tubes having projecting shaft endssecured to them, outer f tubes of larger diameterthan the said main tubes and arranged over portions of the said main tubes at one end of the said frame, and;

distance-pieces secured between the said main tubes and the end portions-of the said outer f tubes, said outer tubes and the exposed portions of the said inner tubes forming'sepa'iating-spaces of diierent width for grading the material.

In testimony whereof I have affixed my signature in the' presence of two witnesses.
