, particularly to means for piling cold rolled metal sheets, and has for one of its objects the provision of means for edging the sheets as they are piled so as to form an accurate pile and eliminate protruding edges which would 1 be burned during annealing of the piled sheets.

Another object is to provide a piling mechanism that Y,may be adjusted to pile various sizes of sheets. i

In the drawings:

Figure 1 is a plan View of a piling apparatus embodyingour invention.

Figure 2 is a side elevation thereof.

Figure 3 is a sectional elevation taken on the line lll-HI of Figure 1.

Figure 4 is a sectional elevation taken on the line lV-IV of Figure 2.

Referring more particularly to the drawings, the numeral 2 designates a belt conveyer which delivers a succession of rolled sheets A into the bite of a air of concave and convex feed-rollers 3, which rollers feed the sheets into the piling mechanism (to be described) and onto an annealin base B.

The belt conveyer 2 is traine over suitable head pulleys 4 mounted on a head shaft 5 which is journaled in suitable bearings in a supporting frame 6. The feed-rollers 3 are also journaled in the frame 6.

A pair of supporting shafts or bars 7 and 8 are secured in the :frame 6 and a screw adjusting bar 9 is journaled in the frame 6 between the bars 7 and 8.

A stationary side guide-plate 10 is carried by the bars 7 and 8 and an L-shaped guidecarrying frame 12 is slidably mounted on the bars 7 and 8 and has a threaded engagement with the screw-bar 9 so that it may be adjusted toward and away from the stationary idegguide-plate 1Q by rotating the screw- A normally stationary end guide-plate 14 having a stem 15 is adgustably secured in a sleeve 16 on the frame 12 and is locked in position by a set-screw 17 The head shaft 5 is a driven shaft and is provided v'ith a sprocket 18 which is con- 1929. v Serial No. 380,046.

nected to a sprocket 19 on the lower feed-` pivotally connected to said slide bar and their other ends connected by links 26y to respective ones of said guide fingers 22 so that reciprocatory movement of said slide bar will cause a swinging movement of said fingers.

The bar 23-is-reciprocated by means of a crank-gear 27 which is meshed with an elongated gear 28 formed'on the lower or driven roller of the feed-rollers 3. The gear 27 is carried by a bracket 29 on the frame 12 and has an eccentric connection with a connecting' 36 has one end eccentrically connected with x the crank-gear 35 and its other end is connected with a crank-arm 37 on a shaft` 38. Suitable crank-arms 39 are secured to the shaft 38 and are connected to the-respective end guide fingers 32 by links 40 so that oscillation of the shaft 38=Will cause the fingers 32 to swing or move toward and away from the stationary guide-plate 14.

In operation, the sheets' A are fed through the rollers 3 and, due to the shape of the rollers 3, the sheets willbe curved transversely so as to render them stiff andlcause them to be fed into the piling mechanism in a horizontal plane. The sheets A will be fed into' the piling mechanism with enough force to cause them to engage the end guideplate ory stop 14'. rlhe swinging side guide lingers 22 and theend guide fingers 32 will be constantly movmg in and out while the sheets are being piled and consequently willimpart a succession of blows to the sheets as they settle between the guides, thus forcing said sheets in against the stationary guide-plates 10 and 14 which form a right angle.

In addition to edging the sheets the

guide fingers

22 and 32, due to their movement, serve to provide increasedclearance between the guides when they swing outwardly so as to permit unrestricted fall of the sheets, thus` facilitating the settling of the sheets.

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

We claim: t

1. A sheet piling mechanism comprising in combination a pair of supporting bars, a stationary side guide member mounted on said bars, an L-shaped guide-carrying frame slidably mounted on' said bars for movement toward and away from said stationary side guide member, means fuor moving said frame on said bars, a normally stationary end guideplate carried by said frame 'and adjustable toward and away-from said frame, a plural- .ity of side guide fingers hingedly mounted onsaidframe so as to depend therefrom vopposite said stationary side guide member, bearings on said frame, a slide bar mounted for reciprocatory movement in said bearings, bell-crank levers pivotally mounted intermediate their ends on said frame, said levers having one end pivotally connected tosaid slide bar and their other connected by links to respective ones of said guide fingers, power means for reciprocating said slide bar tol member mounted on said bars, .an L-shaped guide-carrying frame slidably'mounted on said bars for movement toward and away `from said stationary side guide member,

means for moving said frame on said bars, a normally stationary end guide-plate carried by said frame and adjustable towardand awa from Vsaid frame, a plurality of side gui e iingers hingedly mounted on said frame so as to depend therefrom opposite said stationary side guide member, bearings on said frame, a slide bar mounted for reciprocatory movement insaid bearings, bellcrank levers pivotally mounted intermediate their ends on said frame, said levers having one end pivotally connected to said slide bar and their other end connected by links to respective ones of said guide fingers, and power means for. reciprocating said slide bar to cause a swinging movement of said side guide' fingers. Y

In testimony. whereof, We have hereunto set our hands.,
