GEO. C. KELLOGG AND PHINEAS GlLLET, OF NEW HARTFORD, CONNECTICUT.

MACHINE FOR PICKING AND OPENING WOOL, COTTON, AND OTHER FIBROUS SUBSTANCES.

Specification of Letters Patent No. 1,575, dated April 30, 1840.

T0 all whom, t may concern Be it known that we, GEC. C. KELLOGG and PHINnAs GILLET, of New Hartford, in the County of Litcheld and State of Connecticut, have invented new and useful improvements in the Picking and Opening of iVool, Cotto-n, and other Fibrous Substances Preparatory to Manufacturing Them; and we do hereby declare that the following is a full and exact description.

The nature of our invention consists in an improved mode of feeding the wool or other fibrous substances into the picking machine, and an improved mode of setting and holding firmly the picker teeth into the bags of the main cylinder.

To enable others skilled in the art to make and use our improvements we will proceed to describe them, and also .the old method which has been more commonly used, and the comparative operation of the old and new; and in order to make the description as plain and concise as possible we will refer directly to the drawings, which represent the most common form with our improvements attached.

le build them in all the Variety of forms and sizes to suit the order, or magnitude of the work required, and our improvements are applicable to old and new pickers of every form. y

Figure l represents a picking machine with the internal bands on, and ready to receive the main belt on the opposite side to connect it, with the mill or motive power.

A is a Creeper cloth which is moved by a gear on the end of the Creeper cloth roll, which matches with and is moved by the gear wheel B which is fastened on to the end of the feeder shaft. rThese gears should be of such diameter as to give the Creeper cloth nearly the same superficial speed of the feeder. rThe wool, cotton, or other substance to be picked is spread upon said Creeper cloth. i

G is one feeder weighted down having a concave metallic shell placed under it (which occupies the place of another feeder in the old form). The underside of said feeeder moves with th Creeper cloth, and both to ward the machine, or picker Cylinder, which is inclosed in a bonnet or covering on the top. and a grating underneath to let the metes and dust escape, and open at D where the wool, Cotton, or other substance is dis- Charged.

In order more easily to explain the position and manner of constructing the several parts, we will present an end view of the feeder and shell, together with an end view of a picker cylinder, and of the rollers which move the Creeper cloth, each part in its relative position, detachable from the bonnet or covering within which it operates.

At E, Fig. 2, is a picker Cylinder with ten lags which contain the teeth. Said lags are bolted on to two iron rings (if over 30 inches long three rings will be needed). Into these lags we insert teeth one and onehalf inch apart (either more or less 'to order,) and so set in the different lags that only one tooth follows in the same track each revolution of the Cylinder.

At F is a picker tooth of cast-steel fr@ of an inch in diameter and about 5 inches long from the lag tapering inches to a round point vhich is tempered.

At G, is a short bolt with a screw and init at one end, and a hole at the other, which passes through the lag and against the piCker tooth at rightangles. Through said hole in the end of said bolt said picker tooth passes, as it is slipped easily through said lag against a gage stick represented at L, Fig. 3, which stick is removed after the teeth are set fast by t@ ling the screw nut, and by so progressinf tl e teeth are all set with accuracy and despatch.

F ig. 8 represents a gage stick which is made temporarily fast across the picker frame-and a lag with the teeth in Contact with it when said screw nut mC yes them fast. The picker teeth we set pitching forward in their whole length about of an inch, or as much as possible ani permit them to run clear by the Centrifugal force throwing eli1 the fibers. lt is well to have lthe teeth project inward an extra length which in time `will be used up by repeated sharpening. See those teeth in lag H Fig. 3.

At l Fig. 2 is seen the end of a feeder. At J is seen the end of a shell placed under it. Said feeder re fes the wool or cotton from" the Creeper cloth A., and causes it to slide on the shell J, un 'i it is brought in Contact with the teeth on the cylinder/E, at which time the tee h on the feeder have pierced through the locks or fibers to be picked at the point K, where the locks are gradually and slowly presented and combed or picked over the edge of the shell at K. Said locks are kept in picking Contact by the back of the shell which is made 5 or 6 inches wide, and in a concave form to suit the circumstances of the picker cylinder. The concave side of the shell toward the feeder is made more open onthe side toward the creeper cloth, say from half toy three fourths of an inch according to the material to be picked. The edge lying nearly in contact with thecreeper cloth as it passes over the roller should be nearly to an edge.

`The edge of the shell at K, may be as near an edge as possible and no-t cut the fibers say lg of an inch thick.

It is common to move a picker cylinder with a superficial speed from 36 to 46 feet per second, and the feeders as the pulleys indicate, say one revolution of feeder to 16 revolutions of the picker cylinder. The speed and comparative motions admit of great variations as the work may require.

The feeder and shell may be made of any smooth and solid material. lVe have used cast iron for the shell grinding it smooth on the two concave sides. We have used cast and wrought iron for the spur wheels which constitute the feeder-the latter is preferable for most kinds of work. l/Ve stamp them out of sheetV iron nearly lU of an inch thick. The precise diameter is not important. 7e have made them between 3 and et inches in diameter, including the spurs or teeth, with a hole in the center 1PZ inches in diameter, which nearly resemble circularv saws with teeth near -2- of an inch in length. These saws, or spur wheels are slipped on to an arbor or shaft against a shoulder with metal or wooden collars of about E; of an inch thick' between each until the whole length required is obtained. VVhenfthey are all made fast by a screw `nut pressing them against said shoulderY the collars be-v Y tween said saws or spurs ought to comeout to the Vroo-ts of the teeth.

rPhe teeth of the feeder on the side next to the picker cylinder should pitch downward, and the teeth o-n the picker cylinder next to the feeder should also pitch downward. The top of said cylinder moves toward said feeder.

In the operation of the improved picker the picking is better done because very small mattedlocks are not permitted to escape without being` opened and separated, they being held within lg of an inch of the picker teeth before they are disengaged from the teethof thefeeder, and the shell holds the fibers suspendedagainst the teeth ofthe picker cylinder and effectually prevents them from winding around an under feeder (there being none in our improved kind).

The improvement in setting and holding the picker teeth over the old plan is great, as they can be easily taken out and repointed and again set with accuracy and despatch by the picker tender or a small lad.

VThe objections to the old plan of having two feeders, are, that theycannot be made to hold the wool at a point sufliciently near the points of the picker teeth as to be sure to separate small matted lockis-and not nearer than the semidiameter` of the feeders-and if they are small will be extremely troublecome by the above named improvements.

' What we claim as our invention and desire to secure by Letters Patent is 1. The combination of thefeeder and shell,

and valso their combination with the picker y cylinder as described.`

2. We alsov claim the method of holding and setting the teeth `in the lags by means of the screw staples or bolts as described.
