accompanying drawings, and to the letters of reference marked thereon. p Like letters in the figures indicate the same parts.

Figure 1 shows a side view or elevation of my improved apparatus. Fig. 2 shows a, top

or plan view of the same. Fig. 3 shows the same view as Fig. 1, with the front half of the revolving chamber removed to showthe The object'of my invention is to arrange screw-blanks or other similar articles, and

convey them to a machine where some further operation is to be performed upon them, in a'more uniform and certain manner thanis generally done.

A is a revolving hollow drum'or chamber, of a cylindrical or oblate spheroidal form, one side of which has the circular opening a a a, for the purpose hereinafter described. The other side has the axis attached to its center, on which the drum turns.

y Around the circumference is a slot, '1) b b,

of sufficient width to allow the bodies of the blanks to pass through, but not the heads. This slot is, not continuous, but is broken at the points 0 c c, where the two halves of the drum are united. At these points there are interior radial arms, dd d, attached to the inside of the drum, which have a slot in them, lengthwise, of the same width as that in the circumferenceof the chamber above described. The junction of these radial arms with the drum is curved,'so that blanks, resting in the circumferential slot by their heads, can pass around the curve, and out upon the radial arm.

'- B is a shield attached to astandard, C,

passing through the openingaa a, and is stationary, and does not move with the revolving chamber A. This shield has a curved surface, 0 0, along which" the ends of the radial arms pass close without touching it..-" The Witnesses:

etandard 0 also supports the inclined conforms part of the shield B. These ways curve round, and lead through the opening a a a' to any point where it is desired to deliver the blanks to a machine.

E is a plate attached to the conductingways, for the purpose of ,catchin g and returning to the drum any blanks whichfall from above as thedrum revolves.

The operation of my invention is as follows: The blanks are placed in the drum or chamber A, which is slowly revolved with either a continuous or an intermittent motion, communicated by a belt or ratchet, or any other convenient means. As the drum revolves, the arms (l pass through .the blanks, which fall over and over to the bottom of the chamber. Such of the blanks as fall into the slot b at the bottom, and such as are caught by .the arm d asitpasses through, are forced out upon the arm, resting by their heads in the slot as the arms rises, and fall against the] shield B, which retains them in the arm untilit rises sufliciently high to have its slot correspond with that of the conveyingtrough B, when the blanks pass into it, and are carried forward down the incline. As each successive arm d passes through the blanks in the bottom of the drum it brings up blanks,

as above described, and delivers them into the conveying-trough.

The'curved surface 0 e of the shield-extends down sufliciently far to prevent any blanks which may be taken up by the arms d from being caught drum revolves.

The interior of the drum may be of any form that will conduct the blanks into the slot b.

Claims.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arrangement of the revolving drum 7 A, with its slot b, arms d, and the shield B,- substantially as described.

2. The revolving drum A, with its slot b,

arms 11, and shield B, in combination with the conducting ways D, substantially as described. I
