RECEIVING AND FILING PAPER.'

To all whom it may concern:

Be it known that I, JEPTHA AVERY WIL- KINSON, of Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use certain new and useful improvements in means for receiving and packing sheets of paper or other material as delivered from a printing-press or from a cutter that divides such material into sheets; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, making part of this specication, wherein- Figure 1, is a vertical section of the said means or apparatus, and Fig. 2, is a plan of the same.

Similar marks of reference denote the same parts.

My said invention consists in projecting the sheets through the air in such a manner that they fall in regular succession onto each other, and are taken away by an endless apron or equivalent device to be stacked up in reams, or folded ready for use.

The drawing represents a device at h, for separating the sheets from an endless web, but the sheets may be delivered from any suitable cutter' or printing press.

0, is an inclined table onto which the sheet is delivered and passes between endless bands p, and 293, formed in ranges of any desired number and passing around the rollers and drums p, p2, 33, and 34. These rollers and drums are so located as seen in Fig. l, relatively with the table 0, that the bands p3 travel on the surface of the able 0, and then have an upward direction given to them as they pass below the drum p, and up over the drum 222 whence they return over the roller 3%. The endless bands p, pass direct from the drum p, around the roller 33. The effect of this part of the packing apparatus is to receive the sheet between the bands p and p3 that gradually approach each other, and then impart to said sheet a slightly upward movement as it is projected rapidly from between the bands and drums p and 793 so that the sheets fall successively between the vertical sides ([2 in the manner represented by red lines Fig. l, onto the table or apron u.

In order to prevent the sheets flying upward by any current of air as projected I make use of a series of'belts g, intermediate to the belts 7) on the drum p, said belts g passing around a roller or drum r, that is set in journal boxes on the vertical sides g2. This roller r, as well as the rollers r', r2, r3 and r* are turned with alternating small and large parts or pulleys, so as to receive the endless bands s, in series as shown and said bands pass from the smaller part of one roller to the larger part of the next whereby the speed of the bands is gradually lessened, and if any sheet travels against these bands its momentum will be checked until it finally subsides.

The vertical sides g2 give direction to the sheet and keep it in position widthways and also carry the rollers (A) and bands (8,) forming thereby a trunk or receiver. The bands (s) are kept tight by the weight 35, with a cord over the pulley 36, to the shaft of the roller fr't that revolves in slotted journal boxes, and Q is a weighted roller to keep the bands g tight.

I prefer that the bands 29 and p3 travel faster than the sheet is delivered in order to accelerate its speed and separate one sheet from the next, and to aid in so doing I employ narrow rollers t, t, of india rubber on a cross shaft acting against the outer and center bands Q, g, g, as seen by dotted lines in Fig. 2, to confine the paper to these bands in passing under the drum 79.

By giving motion to the endless apron u, the sheets fall shingling, or one slightly behind the preceding, so that the handling is greatly facilitated and said apron may be conveyed away any desired distance to accommodate folders or packers who may be located at tables on each side thereof. To give motion to this endless apron I use a wheel u2, driven by a band from the shaft of the drum 29, and pinions 37 give motion to the roller u, around which said apron passes and a is a roller at the other end of the table over which the apron passes, said roller being fitted in adjustable bearings for tightening the apron.

IVhat I claim as my invention and desire to secure by Letters Patent, is-

l. The accelerating bands y2 793 and table 0, arranged and acting as set forth to project the sheets of paper successively over each other as they subside in the air, and in In Witness whereof I have hereunto setl my signature this tenth day of June 1859.

JEPTHA A. WILKINSON.
