MECHANISM FOR EVENING SHEETS OF PAPER N FLY-BOARDS OF PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 316,329, dated April 21, 1885.

Application filed October 17, 1883.

To all whom it may concern:

Be it known that we, M. WAGNER BRUSH, of Hyde Park, in the county of Norfolk and State of Massachusetts, and MIroHELL A.

SALoMoNs, of Boston, in the county of Suffolk and State aforesaid, citizens of the United States, have invented certain Improvements in Mechanism for Evening Sheets of Paper on Fly-Boards of Printing-Presses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective View of the fly- I 5 board of aprinting-press having our improved sheet-evener applied thereto. Fig. 2 is a plan of the under side of the same. Fig. 3 is a vertical section of the same on the line at w of Fig. 2. Fig. Iis a vertical section on the line y y of Fig. 2.

Our invention has for its object to provide a simple and reliable device for evenly piling sheets of paper as they are delivered from a printing-press ontothefly-board; andit consists in the combination, with the fly board or table of a printing-press, of two or more adjustable corner pieces or gages adapted to be simultaneously moved diagonally by suitable mechanismtoward and frorna common center,

0 whereby each sheet as it is deposited by the fly upon the pile is jogged at the corners to cause it to lie evenly with respect to the preceding sheets, as hereinafter more particular ly set forth; and our invention also consists in 5 certain details of construction, as hereinafter set forth and specifically claimed.

In the said, drawings, A represents the fly or delivery board or table of a printing-press, upon which the printed sheets are deposited 0 by the fly of the press in the ordinary manner.

At or near each corner of the table A, on the upper surface thereof, is placed atriangular corner piece or gage, B, composed prefer- 5 ably of sheet metal, of the form shown, each gage B having two vertical sides, 6 8, at right angles to each other, and being provided at its bottom,on the outer side, with alip or flange,

(No model.)

a, having a slot, 12, through which passes a thumb-screw, c, by means of which the corner- 5 gage is adj ustably secured to a bar, D, adapted to slide within a guiding-groove, e, in the upper surface of the table A, and lying flush therewith, or nearly so, as seen in Figs. 3 and 4, this. .capability of being adj usted on the bars .55 D enabling the corner pieces to be placed in the exactposition required to suit the shape or size of the sheets of paper delivered from the press. The bars D extend from points near the corners of the boardA diagonally toward the center thereof, and are each provided with a series of holes, f, for the reception of the thumb-screw c of the corner-piece B, whereby the latter can be adjusted to vary its distance from the center of the board A, as may be required for sheets of paper of different sizes. The inner ends of the barsD are covered and confined in place by a plate, (I, secured to the center of theupper surface of the board A.

From the under side of each bar D projects a pin or bolt, 9, which passesthrough a slot, h, in the board A, in line with the groove 6, and carries at its lower end a friction-roll, t, which fits within a curved slot or camway, k, in a circular cam-plate, G, secured to the under side of the board A by means of a screwbolt, Z, around which the cam-plate oscillates.

The cam-plate G is .provided with an arm, m, having at its outer end a slot, 10, in which fits a friction-roll,12-, on a stud projecting from a lever, H, fulcrumed at n, and extending out beyond the edge of the board A, where it is intended to be connected preferably with a strap passing over a pulley on the oscillating flyshaft of the press, whereby it is operated in one direction against the resistance of aspiral spring, I, by which it is returned to its normal position. If preferred, however, the leverH may be connected with and operated by any other portion of the mechanism of the press 0 having the necessary movement at the proper time.

The corner pieces or gages B nearest to the shaft of the fly are provided with notches or open slots 15, to allow the 'fly-fingers .to de- 5 scend without coming into contact therewith.

The operation is as follows: The partsheing in the position seen in Figs. 1 and 2, with the corner gages -B thrust outward to their full extent, the sheet -of paper is thrown over by the fly onto the board A, or the pile of sheets previously deposited thereon, and while the air is beneath the sheet,and before it has had time to settle on the pile, the corner-gages B are simultaneously advanced diagonally toward the center of the board with a quick movement by the oscillation of the camplate G through the connections described, which causes the sides 6 8 of the corner-gages B to strike the corners of the sheet of paper and jog it into a position exactly over the preceding sheet, on which it is thus caused to lie evenly, as required, to produce a perfectly even pile of sheets on the board A. As the fly rises to take another sheet the cam-plate is'oscillated in the opposite direction by the spring I, and the corner gages B thrust outward to their full extent to enlarge the space inclosed thereby. in order to prevent any portion of the following sheets from dropping over the upwardlyprojecting edges of the corner-gagesB.

We do not confine ourselves to the employment of four corner gages B, as shown, as a single pair of these corner-gages arranged to operate simultaneously upon opposite diagonal corners of the sheet may be used in some cases with good results. Neither do we wish to confine ourselves to the precise construction of the mechanism for producing the simultaneous diagonal movement of the corner pieces or gages B toward and from a common center upon the upper surface of the board or table A, as it is evident that these movements may be produced by other suitable mechanism without departing from the spirit of our in vention.

e donot claim a table with gages mounted to slide thereon on four sides of the center, with mechanism, substantially as described, connected therewith for automatically and simultaneously moving said gages toward and from the center. Neither do we claim a delivery-table provided with stop-cleats, an adjuster constructed to embrace two sides of the angle of the sheet diagonally opposite said cleats, and means for reciprocating said adjuster diagonally, and such we hereby disclaim.

WVhat we claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, with the fly-board of a printing-press, of the adjustable corner-gages, the diagonally-arranged sliding bars, and their actuating mechanism, whereby the sheets are adjusted at the corners as they are successively laid, substantially as specified.

2. The combination, with the diagonallymoving slides havinga series of apertures near the ends, of the corner-pieces having vertical sides at right angles to each other, and longitudinally-slotted bases, and the pins and nuts whereby the gages may be adjusted in two directions, substantially as and for the purposes specified.

3. The combination, with the fly-board, of the diagonal ly-moving slides, the corn er-pieces having vertical sides, the cam-wheel whereby the slides are advanced or retracted diagonally, and the lever by which motion is imparted to the cam-wheel, substantially as specified.

Witness our hands this 3d day of September, A.-D. 1883.
