FEEDER.

Application filed January 3, 1925. Serial No. 405.

rlilhis invention relates to a feeding device, the general object of the invention being to provide means for feeding a very small quantity of material from a receptacle containing the same so that this material can be mixed with other material.

Another object of the invention is to pro vide means for regulating the amount of material fed by the device.

1U `While the invention is mainly designed for feeding bleaching material to liour it will of course be understood that the apparatus can be used for other purposes.

This invention also' consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, il lustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in det-ail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which z- Figure l is an elevation of t-he improved apparatus.

Figure Q thereof.

Figure 3 is an enlarged sectional 'View through the drum or receptacle for containing the material to be fed.

Figure l is a detail sectional view througl'i the drum.

Figure 5 is a view of one of the gates.

In these views, l indicates a supporting` member which has the bearings 2 at its upper end for the horizontally arranged hollow shaft 3. A pulley 4 is Connected with one end of said shaft so that the same can be rotated from any suitable source and a drum 5 is connected with the other end of the shaft. This drum is of substantially elliptical shape in vcross section and has a -circumferentially arranged rih G which has grooves 7 in its sides and perforations are formed in the drum and pass through the center of said rib, these perforations permitting the material to pass from the is a longitudinal sectional view CIL drum into a chute 8 which is supported by the extension 9 of the support l. An opening lO is formed at the center of the outer side face of the drum so that the material can he placed in the drum, this opening bemg closed by a cover 11. D

In order to insure the passage of the material through the small perforations I place a presser foot l2 on an arm 13 which is secured to a shaft 14 by a set screw 15, said shaft passingthrough the hollow shaft is il and having its end bent twice at right angles and secured to a projection 16 on the base or support l so that the shaft lilis held against rotation. A spring 17 presses the enlarged end of the foot against the perfo- G5 rated part of the drum so that this part 'of the foot prevents clogging and insures the passage of the material through the perforations as the drum is being rotated. rlhe parts are so set that the foot always engages that part of the drum which is lowerinost so that the material passing through the perforations will drop into the chute and thus pass to the point where it will mix with the other material.

In order to regulate the amount of material fed from the drum I provide a plurality of gates 18, each gate being' of channel shape so that it will embrace the rib with its eX- tremities engaging the groove 7. Thus the gates are slidably mounted on the rib and can be manually adjusted to cover or uncover the perforations so that a number ot' perforations can be covered to cause the device to feed the correct amount of material.

lWith this invention a small amount ot' material is fed from the drinn and by moving the gates the amount of material can be varied to suit conditions.

It thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the G5 several parts, provided that such Changes fall within the scope of the appended claim.

What I claim is A device of the character described comprising a supporting base, a hollow shaftthereon, an elliptical shaped drum attached to one end o1 the shaft and having a plurality of ercmnferentally arranged perforatons, a rib exending around the drum in alignment with the perforatlons, grooves on opposite sides of the rib, channel Shaped gates embracing the rib and movable n said grooves, Said gates adapted to be manually moved over the rib to open and close sad perfor-ations, said gates being 'rotonally retained against accidental movement and a spring pressed foot Supported by the slla' having engagement with the perforated part of the drum to assure of passage through the peror'ations.
