Application l'ed .Tune 2*?, 1913. Serial No. 776,166.
.To all whom it may concer?. I
Be it known that I, WILLIAM F. MINNICK, of Niles, in the county of Trumbull and .State of Ohio, have invented certain'new and useful Improvements in Sheet Feeds or Separatore; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same.
This invention relates to sheet-eeds or separators, and is especially designed for handling glazed or coated maternal and also comparatively thick stock, such as cardboard or pasteboard.
ln. the accompanying drawings, Figure ll is an elevation showing a portion of afeeder equipped with my improvements. Fig. 2 is a view in perspective of a portion of the separator. Fig. 3 is a plan view thereof. Fig. 4 is a section on line LL--filfig 3.
The distinguishing characteristic of my present invention resides in effecting the bucklingr of sheets from opposite corners toward each other b reciprocating means designed to engage t e edges of the sheets andy to be moved inwardly overtlie pile suilicientlyto buckle the topmost sheet so that it may be removed by any preferred 'meansl In the drawings l have shown Amy invention applied to a feeder of the type disclosed in the application for patent or Charles Harris, filed February 19, 1910, Serial No. 544,753, and my improvements may readily be applied to the' Harris feederv vwithout involving any material change 'inl The parts are du licated at construction. U each side of a ile of stock and t e description of one series of elements will apply to l have shown a'verticallymovable suctionn separator 1 carried by an arm 2; an air eject ing presser-foot 3 carried by'an arm li; and
a buckler 5 which iscontrolled by an arm 6,I
alici which arms are engaged by suitable earnsl mounted on a common operating shaft which may be driven by any suitable agency. lt is not necessary to refer in detail to the construction of either the suction-separator or the presserdoot and blower.
The buckler 5 is in effect a pusher. llt rests upon a pile of stock, near its edge,
`is provided on its under surface with a protruding edge or progcetion which is de projectin signed to engage the edge of the stock. lt is only necessary that the buekler be reciprocated inwardly, transversely of the pile, suflicientl y to buckle the top sheet, and when the latter is taken 'up by the separator the buckler is returned to its startin point, be`
ing moved suciently far to ena levits edge or projection 7 to clear and engage the edge of the top sheet. rlhe particular formation of the buckler is immaterial. In general, it is substantially the pusher of patent to John F. McNutt, No. 605,328, of June 7, 1898, with the difference in construction that the projection is o n the underside instead of on v mounted on the lower end of an outwardly 'Il arm of a lever 10.l A post 12 of the stud 1s connected by a springl to a post leextending outwardly from the lever, said spring tending to always hold the buckler under sufficient ,tension against the top of the pile.
The lever 10 is l'ulcrumed at l5 on the front face oi' a vertically-disposed plate i6 secured to a frame 17 which carries the several units composingvthe separating device. The lever l0 has a slot 18 extending longh tudinally therein but at aslight angle to the axis of the lever, and into this slot projects the end'of a rod or shaft 19 which is also.l projected through a straight slot 20 in the' supporting plate 16. The rod or shaft 19 is carried by the arm' 6. I have shown this rod or shaft as mounted in a bearing 2l pivf oted concentrically to the operating shaft 22 on which the several cams are located, and as having a friction roller 25. The bearing '21 is connected to the arm@ by means of a rod v26 so that as said arm is raised by its respective cam 27 the rod or shaft 1i? will r f upwardly in the slotso the lever. l@ ar plate i6, and by reason ci the pitch ci? slot in the lever will cause the latter to move outwardly and carry the bucklervvvith it. As the cut-out or 'depression @e oiy com is brought beneath the friction roller 29 of arm 6 the latter will be immediately lowered, causing the quick descent of the rod or-shaft 19, and the consequent quick inward movement of lever 10 and with it the buckler. To insure the quick downward movement of arm S I preferably connect to rod 26 a spring' moved inwardly by the lowering of the actuating rod or shaft 19 will through the projecting edges on their under surfaces engage the opposite edges of'tlie topmost sheet at opposite sides of the pile, and being moved inwardly will effect the necessary vbuckling to permit suchsheet to be taken up by the separator and removed from the pile by any suitable means, not shown. In this connection it will be understood that the presserfoot is raised from the pile and moved outwardly and then forwardly to eject air beneath the topmost sheet and to re-engage the pile. On the return movements of the `actuating rods of 'shafts 19,-'effected by the raising of their carrying arms 6, the bucklers will be moved outwardly to permit the edges or projections 7 to clear the edges of the pile and be in position to engage the topmost member thereof when again moved inwardly.
The advantages of the present invention will readily be appreciated by those skilled in the art.

I claim as my invention:
