Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a feeder, a rotary feeding head, a flattened portion on the periphery thereof said head having -supplementary suction passageways communicating with said fiattened portion, a main suction passageway communicating with the periphery of the feeder head, al suction means adapted to apply suction to said passageways whereby the leading edge of a sheet to be fed will be drawn against the flattened portion of the feeder head and bent at an angle to the sheets upon which it rests.

2. In a feeder, a rotary feeder head a flat-- tened portion on the periphery thereof, said head having suction passagevvays a portion of 'which communicate with the flattened portion of the periphery and a portion of which communicate with the rounded portion of the preiphery, means to applysuction to such passageways, said feeder head having a suction groove on the side thereof adapted to release the suction of the suction means. .i g f 3. In a feeder, a rotary feeder head a flattened ortion on the periphery thereof, said head avin suction passageways al portion of whic communicate with the fiattened Aportion of the peripher land aA portion of means, means to move a sheet to be fed in the reverse direction to that in which it is to be fed to buckle the sheet, said means'having a suction passageway therethrough, and said feeder head having means to coincide thereoint adjacent the flattened portion of perlphery on the feeder head to cause said bucklin just prior to bendin the sheet against the iattened portion of t e periphery of the feeder head. 1 y

4. In combination in a feeder ofy a. rotary feeder head having a flattened portion on the periphery arid a plurality of suction apertures communicating with thev periphery andthe side of the feeder head, a portion of said passages communicating with the flattened portion ofthe periphery and a portion with the curved 'part of the periphery; suction means adapted to be intermittently connected4 to the apertures on the side of the feeder head, said feederhead having a4 suction relief groove on the side-thereof, meanstion means adapted to be intermitten y con nected to the apertures on the side of the feeder head, said feeder head havin a suction relief groove on the side thereo means to flutter the sheets being fed Aby the feeder head, suction means movin in the reverse direction to the direction o rotation of said feeder head, a common ower means for operating the feeder hea and the reverse mechanism, said reverse mechanism havin the same suction means as the feeder hea said feeder head having a passageway therethrough for communicating the suction from the suction means to the reverse means.

6. In a feeder, a disc having an aperture therethrough from side to side and a plurality of apertures on the side thereof coma portion of said apertures communicating with the rounded portion of the periphery and another portion communicating with the flattened portion of the peri hery the flattened portion of, the perip ery shoulder at, one end and suction means adapted to slidably engage the side of said feeder head over said apertures, said feeder head .having means to release said suction when the suction means has'been dl laced from the a ertures on the side ofthe head.

7. Infa ceder, a disc havin an aperture therethrough from side to si e and a pluralit of apertures on the side thereof communicating with the periphery of the disc, a portion of said apertures communicating with the rounded portion of the periphery and another portion communicating with the flattened portion of the periphe a flattened portion of the periphery aving a shoulder, at one end and suction means adapted to slidably engage the side of said .fee er head over said apertures, said feeder head having means to release said suction when the suction means has been displaced from the apertures on the side of the head, a buckling disc slidably engaginer the side of the feeder head o posite to the suction means, said buckling disc havin an a erture through the side tp the periphery t ereof, i

municating with the periphery of the disc, v

having a the side aperture being adapted to engage with the first-mentioned side aperture through the feeder head, and a common driv-` 'ing means for the feeder head and the reverse means whereby said feeder head and reverse means operate in opposite direction and are intermittently and successively operated with said suction means to buckle and inject a sheet. A

8. A new article of manufacture for use as v a feeder head, consisting of a disc having a periphery with fiat-tened portions and' shoulders ad'acent said Hattened portions and aplurallty of suction passageways, a y

portion of which connect with the flattened periphery and a ortion with the rounded periphery of theieeder, al1 of said passagel0 ways communicating with apertures on the side ofthe feeder'.

In testimony whereof, I aflix my signature.
