PILINQ; AND PACKING APPARATUS Application m d September as, 1927. Serial "Ne. 222,680;

This invention relates to packing and piling apparatus for packing and piling sheets and b plates in connection with tin mill apparatus piled by hand on an annealing stand or other support in readiness for the next operation which generally s an annealing operation. Thepresent invention provides an automatic packer and piler which entirely dispenses with the manual labor hertofore used to pack and pile the'sheets and plates.

In the drawings Figure 1 is a plan view of a packer and piler constructed in accordance with this invention.

Figure 2 is a side elevation thereof. 1 Figure 3 is a perspective elevation of a modified form of stop and guide member.

Referring more particularly to the drawings, the numeral 2 designates a conveyer for delivering the sheets and plates to be packed and piled.

. The packer and piler comprises a frame 3 in which is journaled a concave feed roller 4. A convex feed roller 5 is journaled .in a pair of arms 5 pivotally secured to the frame 3.

A screw shaft 6 is journaled in the frame 3 and is provided with a crank handle 7 by which it may be rotated. A pair of right and left-hand threaded nuts 8 and 9, respectively,

1 are threaded on the shaft 6 and are. supported by a rest bar or rail 10. c

A pair of

side bars

12 and 13 are secured to the nuts 8 and 9, respectively. Each of the

bars

12 and 13 is provided with a side guideplate 15 which is flared outwardly at its upper edge, as at 16.

A mounting disk 17 is provided with diametrically opposite screw threaded arms 18, which arms project through apertures adj acent the rear ends of the

side bars

12 and 13, and are held in place by jam-nuts 19.

The disk 17 is provided with a centrally disposed aperture in which a threaded bar 20 is slidably mounted." A pair of jam-nuts 21 ar .in position in said disk.

.A combined stop and guide-plate 22 is -secured to the inner end of the bar 20 and comprises a vertical pile forming portion a,and a curved guide portion 6. The curved guide portion b of the plate 22 is bent forwardly in the direction of travel of the sheets and plates, from the upper end of the vertical pile forming portion a, and then .curved rearwardly and upwardly so as to extend materially rearward of the vertical plane of the 7 vertical portion a.

are provided on the bar 20 for locking said I A rearpile guide 24 is secured to the frame 3 to guide the rear end of the sheets and plates. An annealing box base 25 or other support is adapted to be located below the packing and piling mechanism to receive the pile of sheets or plates. In operation the sheets or plates, designated by the letter. Y, are fed into the bite of the

feed rollers

4 and 5 of the packer and piler. The rollers ,4 and 5, due to their respective concave and convex shape, will bend the sheets or plates transversely as they pass between the rollers, thereby stiffening the sheets and plates so as to prevent them dipping or sagging." The

rollers

4 and 5 will project the sheets or plates forwardly against the stop-plate 22 at a point adjacent its upper end and due to the novel curved shape of the stop-plate 22, the forward end of the sheet or plate will be guided downwardly while it is still being projected forward. The curve of the stop-plate 22 is suflicient to permit'the sheets or plates being piled to pass from between the

rollers

4 and 5, and after the sheet or plate leaves the rollers 4 and tated by means of the handle 7 so as to cause the nuts 8 and 9, to travel along the shaft 6, either toward or away from each other, as desired. i

Since the side bars 12 are secured to the nuts 8 and 9, the bars 12 and side-guides 15 will be movedwith the nuts 8 and 9. After the side-guides 15 are correctly positioned the jam-nuts 19 will be tightened so as to center the shaft or bar 20 carrying the stop and guide-plate 22. The bar or shaft 20 will then be moved forward or rearward, as desired, to correct position and the j am-nuts 21 tightened to lock the plate 22 in position.

In Figure 3 we have shown a slightly modified form of stop and guide-member 22, composed of a plurality of bars or fingers 30 mounted in a base 31 and having the guideportion 6 and pile forming portion a.

While we have shown and described one embodiment of our invention it will be understood that we do not wish to be limited thereto since various modifications may be made without departing from the scope of our invention as defined in the. appende claims.

We claim- 1. In a sheet mill apparatus, means for feeding sheets and lates out over a support, and a stop for limiting the movement of said sheets and plates and for causing said sheets and plates to descend by gravity in an orderly manner forming a pile, said sto comprising a wall member having a straig t vertical pile forming portion and a curved guide portion, said curved guide portion bein bent forwardly from the upper end of sai vertical portion in the direction of travel of said sheets and plates and then rearwardly and upwardly, said curved guide portion being adapted to engage the forward ends of the plates and sheets and direct said sheets and plates downwardly toward said support.

2. In a sheet mill apparatus, a pair of feed rollers adapted to project sheets and plates to be piled out over a support and a stop for limiting the movement of said sheets and plates and for causing said sheets and plates to descend by gravity in an orderly manner forming a pile on said support, said stop being adjustable toward and away from said rolls, said stop comprising a wall member having a straight vertical pile forming portion and a curved guide portion, said curved guide portion being bent forwardly from the upper end of said vertical portion in the direction of travel of said sheets and plates and then rearwardly and upwardly, said curved guide portion being adapted to engage the forward ends of the sheets and plates and direct said sheets and plates downwardly toward said support.

3. In a sheet mill apparatus, a pair of feed rollers adapted to project sheets and plates to be piled out over a support, one of said rollers being convex and the other of said rollers being concave whereby said sheets and plates are curved transversely so as to stiffen them and cause them .to be projected over said support without dipping or bending, and a stop for limiting the movement of said sheets and plates and for causing said sheets and plates to descend by gravity in an orderly manner forming a pile on said support, said stop being adjustable toward and away from said rolls, said stop comprising a wall member having a straight vertical pile forming portion and a curved guide portion, said curved guide portion being bent forwardly from the upper end of said vertical {portion in the direction of travel of said sheets and plates and then rearwardl and u wardly, said curved guide portion being adapted to engage the forward ends of the plates and sheets and direct said sheets and plates downwardlgntoward said support.
