The present invention eliminates the difficulties encountered heretofore by providing a sheet aligning device in which there is a pair of horizontal members between which the sheets are adapted to pass edgewise disposed thereto and these members are interconnected so that when reciprocated they engage the opposite edges of the sheets alternately and move them into their correct positions. All forces are applied to the edges of the sheets and in the plane of the sheets. The buckling oi oversized sheets is eliminated since they are free to move under the action of either of the positioning members because the member-sengage the opposite edges of the sheets alternately. The present device is adapted to align sheets which vary from their correct position on a conveyor a maximum amount, sinee the positioning members are recipro cated toward and away from the respective sheets. i

Referring more particularly to the drawings, there is shown a pair of base members 1 and .2, which may or convenience be a part of the machine to which the device is attached, or they may be secured to a suitable foundationadjacent a conveyor. Suitable extensions or supporting members i and 5 arebolted at their lower ends to the

members

1 and 2. respectively and have their upper ends pivotallysecured to the center portion to a pair ofupright members 6; and 7. l The upper ends of the upright members have suitable sleeves, formed there in adapted to accommodate a pair. of

arms

8 and 9 which are held in position by the bolts 10 :and which likewise have sleeves termed at their ends to accommodate the sheet engaging members 14 and 15fsecurely held in position the bolts 16. The lower. ends of the iipright members are pivotally connected to the rod17. which correlates the moyements of the sheet engaging members so. that the opposite edges of the respective sheets are engaged alternately thereby.

' The supporting member a is extended beyond and' downwardly from the pivot 18; until it is substantally. U-shaped, and

suitable bearings

20 and 21 are formed in the legs of the U to accommodate a shaft 22 eX- tending therebetween. A earn 2% is mounted on the sha'tt 22 and is adapted to engage a cam follower 26 mounted on the lower end of the upright member 6 and held in contact with the cam by means of the spring 28 attached to the upright member, 7 and support The rotation of the shaft 22, oscillates the upright members and the sheet engaging members 12 and 15 by means of the cam 24 to properly position the sheets. A gear 30 on shaft 22 meshes with gear 31 on shaft 32 to rotate the cam and to operate the device. The shaft 32 may be mounted in suitable bearings M on the

members

1 and 2 and may be operatively connected to a driving mechanism through the gear 36 thereon.

It will be noted that the sheet engaging members 1 1 and 15 are bent outwardly t'o afford a greater distance between the forward ends thereof than between the other portions of the members. The reason for this'is to accommodate sheets varying from their correct position a considerable amount. Such sheets will be engaged by the flared ends of the members 1% and 15 and pressedinwzrd-ly by successive engagements of thesemembers therewith, until the sheets are sufl iciently near their correct position to be" aligned by the straight portions of the members 14; and 15. Iii this way sheets may be positioned without any tendency V to buckle them.

In Figures 5 and 6 of the drawings, the present invention is shown applied to. the de livery end of an 'ovenO from which sheets are about to be transferred to the conveying mechanism a1 and to the lacquering ma: chine 42. The oven 40 comprises generally a conveyor H having U-shaped supporting wires adapted to convey metallic sheets in an upright position past the

sheet engaging members

14 and 15 of the sheet aligning device which is. designated as a whole by 39. After being aligned, the sheets are laid flat upon the conveyor 41 whichdelivers them to a suitable lacquering machine. Both'the conveyor andthe; sheet positioning device are actuated by the gear seeperaav'ei con nected to the motor 43 through the worm gear 46, shaft ll, gears 48 and 49 and shaft 50. The sheets resting upon the supporting members ll) are engaged by the reciprocating positioning members 14 and 15' and pressed into correct alignment prior to their delivcry to the conveyor 41 and as a result they reach the machine'42 in correct alignment, and each sheet isin' position to receive designs or advertising matterin predetermined rotation to other designs thereon or to the edges of the sheets.

lVhile the preferred embodiment of the invention is described in detail'with reter ence to th e'drawings herein, i t is notintended to limit the invention to the present disclosure, as'm'any'changes can be made without departing from the spirit of the invention, andtheretore the description is to be taken as illustrative and not in a limiting sense, as the scope of the invention is defined in the claims.
