FEEDING MECHANISM FOR WOOL-WASHlNG MACH-INIES.

SPECIFICATION forming part of Letters Patent No. 411,534, dated September 24,1889.

Application filed January 17, 1887. $erial No. 224,649. (No model.)

To ctZZ whom it may concern:

Be it known that we, FREDERICK G. SAR- ennr and ALLAN O. SARGENT, of Graniteville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Feeding Mechanism for oolashing Machines, of which the following is a specification.

Our invention relates to feed mechanism especially adapted for feeding wool and other similar fibers to washing-machines; and it consists in certain new and useful constructions and combinations of the several parts thereof, substantially as herein after described and claimed.

In the drawings, Figure l is a side elevation of a feedingmachine constructed according to our invention with a portion of one of the sides broken away to show the construction of the operating mechanism. Fig. 2, is an end view of the same.

A A is the casing of the machine, which is constructed in the general form of two sides and an end of a box. upon feet. An apron 0 forms the bottom of the box and runs over rollers c c. The ends of the shaft of roller 0 are mounted in boxes in the side casing A, and on the projecting end of one of them is attached the pulley p,by which it is driven from any suitable counter-shaft. The apron 0 runs in the direction indicated by the arrow, and with many kinds of long wool it is found necessary to incline it upward toward the vertical face of the toothed apron a in order to prevent the wool piling up against the latter too much and choking and ologgin g the action of it and undue felting of the wool. The apron (L runs over the rollers a a a and takes up the wool brought against its lower vertical face by apron 0. These aprons are shown in our Patent No. 266,900, granted to us October 31, 1882 but in that patent the apron 0 did not incline upward toward apron a, as above described, and consequently with long wool too great a mass or body of it lay against the vertical face of the apron a, while with the apron O inclined upward, as described, the excess of wool dropping from apron Ct continually rolls away from it to the lower end of apron C and is brought up again by the latter in the proper quantity as wanted.

To adapt the mechanism to feed forward different lengths of wool, the apron C has its roller 0' made adjustable up and down, as follows: The shaft of this roller projects at each end beyond the faces of casingA and is mounted at each end in a box m. A slot '8, curved in an arc of which the axis of roller 0 is the center, is made through the face of easing A on each side. Each box or has an ear overlapping the slot 3 on its side, and bolts and nuts m m pass throughslot sand this car and secure the box at in any desired position. The length of slot 8 is such that the roller 0' and its end of the apron may be raised to or above a level with the roller 0 or lowered, so that the apron will incline upward toward the latter roller, as may be required by the length of wool being fed forward. A doffer B knocks the excess of wool off of apron Ct back upon apron C. It is covered with projecting pins Z), covered with copper, on part of its surface and inclined pins 1) 011 other parts for that purpose. The inclined pins 1) are set in the same transverse plane to the axis of the doifer as the pins b part way round the same. The apron a is driven by a pulley 13, attached to the end of the shaft of roller a A pulley p 011 the same shaftis belted to the pulley p on the shaft of the doifer D by a cross-belt. Another pulley p" on the other end of the shaft of roller a is belted to pulley p on the shaft of doffcr B, and pulley p 011 the latter shaft is belted to pulley p on the shaft of the roller c of apron E.

The apron E is employed to carry away the wool as it drops from the reversed teeth of apron a, and to facilitate this delivery of the wool from apron a a doffer D is employed, which has a faster surface speed than that of apron a and is provided with teeth or fingers inclining backward from the direction of rotation of the dofier, as shown, to prevent the winding of the fiber upon said teeth or fingers. The apron E revolves upon rollers e e and is inclined upward to carry the fiber over the edge of the bowl of the washing-machine and deliver it into said bowl directly from the apron a.

To enable the apron E to take any wool from the teeth of the apron a which has not been knocked off by doifer D or previously fallen from the teeth, the apron E has its roller e so set as to bring it at that point contiguous to the apron a, where the latter passes its roller a and changes its direction of incline from forward and downward to backward and downward, thus causing its teeth to open or draw apart at that point and allowing the frictional contact of apron E to easily withdraw the wool from between the teeth.

The operation of the mechanism is as fol lows: The dry wool is thrown into the box on top of apron O, which carries it forward to apron a, and the latter constantly takes up on its teeth a certain quantity of the wool and carries it upward past doffer B. Any excess of fiber is knocked oif by the doffer B or falls off of the surface of apron a back onto the apron C. On passing over roller a the teeth of apron a are reversed, and the doffer D, working against them and against the inclined surface of apron a, shoots the sheet of fiber evenly forward upon apron E to be fed to the next machine. This feed mechanism thus delivers an evener quantity of fiber to the washer in a given time than can be done by hand and without the use of skilled labor and judg ment in supplying the same to the machine in an even quantity.

If desired, the doffer D may be dispensed with; but the operation of the feed is more certain when it is used.

What we claim as new and of our invention 1sthe feeding-apron a, provided with teeth or spurs andarranged to move vertically upward over roller a and thence downward over roller a and the apron -O, forming the bottom of the receiving-box and arranged with one end adjacent to the vertical face of apron a and with its upper surface inclining upward from the opposite end toward the former from a horizontal plane, whereby the surplus wool 1. The combination of the receiving-box,

dropping thereon from apron a will tend to roll away from the foot of the latter by the action of gravity toward the farther side of the receiving-box, substantially as described.

2. The combination of the receiving-box, the apron O, forming the bottom thereof and having its roller 0 adjustable up and down therein and adapted to incline the upper surface of the apron downward toward the same with relation to a horizontal plane, and the apron a, provided with teeth or spurs and arranged to move vertically upward over roller (1 and downward over roller a substantially as described.

3. The combination of the receiving-box, the apron C, forming the bottom thereof, the apron a, provided with teeth or spurs and arranged to move vertically upward over roller a and thence downward over roller a and over the intermediate roller a which latter is arranged to bring the faces of the apron on each side of it at an angle with each other in passing over it and to open its teeth apart, and the apron E, revolving contiguous to and taking the fiber directly from said opened teeth of aprona and opposite to said intermediate roller, substantially as described.

4. The combination of the receiving-box, the apron C, forming the bottom thereof, the apron (1, provided with teeth' or spurs and arranged to move vertically upward over roller a and thence downward over roller a and over the intermediate roller a which latter is arranged to bring the faces of the apron on each side of it at an angle with each other in passing over it and to open its teeth apart, the doifer D, arranged to act upon the fiber carried by apron a above said roller a and the apron E, revolving below said doifer and contiguous to and taking the fiber directly from said teeth of apron a, where so opened apart and opposite to said intermediate roller a substantially as described.
