Application filed November 4, 1918. Serial No. 261,110.

To all whom it may concern Be it known that we, ROBERT FrNs'rnR an PERCY WILSON, citizens of the United States, residing at Erie, in the county of Erie and Stateof Pennsylvania, have jointly invented certain new and useful Improvements in Paper-Sorting Machines; and we 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, reference being had to the accompanying draw ing, and to the letters of reference marked thereon, forming part of this specification.

Our invention relates to paper sorting machines and has for its ob ect the construction of a machine whereby sheets of'paper can be readily inspected for defects .and delivered into difierent receptacles according to the perfection existing in the sheets.

To accomplish this result we have devised a machine. in which the paper sheets are delivered-to traveling carrier tapes and during its traverse over the tapes the operator can inspect it and speedily detect de ects in the sheet, and at the-end of such traverse there is provided manually operated deflectors, whereby 'the further travel of the sheet may be deflected into one path or another as said inspection has shown to be necessary; and

beyond these deflectors suitable rolls and tape carrier mechanism areprovided to carry the sheets along the pathsto which they have been deflected, and deposit them in suitable receptacles provided therefor. For aiding the operator to more speedily de" tect defects in the sheets passing over the tapes,-we preferably provide our device with an illuminating device consisting substan tially of suitable lights located under the path of the sheet as it moves forward.

The features 'of our invention are hereinafter fully set forth and described, and diagrammatically illustrated in the accompanying drawing in which The figure isa diagrammatic side view in elevation illustrating the features of our invention.

In the drawing the carrier tape mechanism A and A and their driving rolls A, A and A are of the usual type and operated .in the usual manner as are such tapes and rolls in the common type in sheet conveying machines, ruling machines and other machines of that character, and are-simply utilized in combination with the features of our invention hereinafter described.

As shown diagrammatically, the tapes A lead from sheet delivery mechanism of any of the usual types (not shown) adapted to deliver sheets one at a time to said tapes, and preferably spaced a short distance therefrom and in line therewith there is 'a second set of conveyor tapes A supported on rolls A and A and preferably between the rolls A and A there is a reflecting mechanism F provided with suitable lights F, and on top of this reflector there is a plate of glass f in line with the carrying surface of the tapes 'A and A the reflector F operating to throw a strong light from the lights F upon the under surface'of the sheet passing over the glass F so that the operator can quickly detect any defects in such sheet; the mechanism can, however, if desired, be used without the lights F with good results.

Between the roll A and the rolls C, C

and the .rolls E, E there are mounted hinged deflectors H and I. These deflectors H and l[ normally lie in a horizontal position, as illustrated in full lines in the drawing, and when inthat position a sheet passes from the tapes A on through and on to the carrier tapes B, B and is by them delivered .into the receptacle 1.

These deflectors H and I are provided at their ends with pins 71. and i, which extend outwardly so as to be engaged'by arms J, J", on a hand lever K mounted at its lower end on a bearing 1L and adapted to be rocked right and left thereon- Under the deflector H there are sheet guides m,-m, leading to the carrier tapes D, D, adapted to direct sheets deflected by the deflector H to said carrier tapes, by which such sheets are con-- and. its supporting roll mechanism E, E,

E E and the receptacle 2 for receiving sheets delivered by the carrier tape mechanism D, D, are of the usual and common type used and operated in sheet conveying machines, such as ruling machines and machines of that character, and the rolls and tapes are driven in the usual manner in and therefore further description of their constructlon and operation such machines,

p then in their normal horizontal positions,

' nism adjacent to the rear side of and sheets from the carrier tapes A pass over them to the carrier tapes B, B; when, however, theoperator discovers slight'imperfections in asheet as it is conveyed by the tapes A, he at once moves left, whichoperates to raise the front edge of the deflector H and deflects such sheet downward between the guides at, m, to the carrier tapes I), I), by which it is delivered in receptacle 2. If, however, the sheet as it passes overthe tapes A, is shown to be more seriously defective, then the lever K 1s moved to the right, which operates to ra1se the front edge of the deflector I above the path of travel of the approaching sheet, and deflects such sheet downward against the guide N, and to the waste, not shown.

It is believed from that from the foregodescription of the features of our invention and its operation, that others conversant with the art can fully understand and utilize the same; therefore what We claim as new and desire to secure by Letters- Patent is 1. In a sheet sorting mechanism comprising spaced tapes adapted to carry sheets, two deflectors, one behind the other adjacent to the delivery end of said carrier-tape mechanism, an oscillating lever, arms thereon for engaging and operating said defiectors, and duplicate carrier tape mechasaid deflectors, one of which is adapted to continue the travel of the sheet in a. continuous direction, and the other in a deflected direction, substantially as set forth.

2. In a sheet sorting machine, comprising spaced tapes adapted to receive and convey sheets of paper thereon, lighting mechanism between said carrier tape mechanism, a movthe lever K to the able sheet deflectmg device for changing the line oftravel of the sheet adjacent to thedelivery end of said carrier tape mechanism, and means for operating said deflector, substantially as setforth.

3. In a sheet sorting mechanism, comprising s aced tapes adapted to convey sheets, mova le deflectors ad acent to the delivery end of said-carrier tape mechanism, a manually operative lever for operating one of said deflectors at a time, carrier tape mechanism at the rear side of said deflectors adapted to receive and continue the travel of the sheet either in its direct or deflected line of travel, substantially as set forth.

, 4. In a sheet sorting mechanism, comprisingspaced tapes adapted to receive and convey sheets, of paper thereon, a lighting mechanism between said carrier tape mechanism, a reflector under said lighting mechanism for directing the light againstthe un der surface of sheets passing over said carriertape mechanism, a deflector adjacent to the delivery end of said carrier tape mechanism, a manually operated lever at one side I of the machine adapted to engage and op-' crate said deflector, -substantially as set forth. v

- 5. In a sheet sorting machine, comprising spaced tapes adapted to receive and convey sheets of paper thereon, a lighting mechanism between Said carrier tape mechanism,- duplicate movable deflectin devices adjacent to the delivery end of said carrier tape-mechanism, a manually operative lee ver adapted to operate one of said deflecting devices at a time toch-ange the line of travel of the sheets into one of two paths of travel, carrier tape mechanism to convey the sheets either in their direct line of travel, or in their deflected line of travel, and receptacles at the .delivery endsof said carrier tape mechanism to receive sheets delivered therefrom, substantially as set forth.

- In testimony whereof we afiix our signatures.
