To all whom t may. concern: Y

\ Be it known that I, CHARLES GRANT HAR- RIs, of Niles, in the county of Trumbull and State of Ohio, have invented certain new and I useful Improvements in Deliverers for Printing-Presses; and l 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.

The object of this invention is to automat--V ically regulate the discharge of stock, such as bags, from a printing-press onto areceiving-table in suchmanner that it will be gradually piled onsuch table without rubbing or smearing and from which'it may be readily The invention will be hereinafter fully set forth, and particularly pointed out in the claims. v

1n the accompanying drawings, Figure 1 is a plan-view. Fig. 2 is a side elevation. Fig. 3 is a similar view showing the retardingwheels raised in dotted lines. Fig. 4L is a diagrammatic view.

Referring to the drawings, 1 designatesa' eonveyer composed of a series of endless bands or tapes onto which bags are discharged vas they leave the press impression-cylinder,

a portion only of which is outlined at 2. These tapes are caused to travel in the direction of arrow 'w by any suitable connection with the press-gearing. At their louter or rear ends these tapes overlap a second conveyer, likewise composed of a series of tapes 3, extended rearwardly some distance from the rst series, and preferably on an incline toward the rear. These tapes 3 engage rollers-4 and 5, the former mounted in brackets secured to a crossrod 6, While rollers 5 are fast on a shaft 7, to which power is intermittently applied to effect the gradual advance of the. tapes.

` lby ak swinging arm 9 and engaging aratchet This is- .preferably accomplished by a pawl 8, carried is secured to a rock-arm 13, which is actuated by a rotary cam 14'. The rotation of the latter imparts, through the means described, agradual rearward travel to the upper iiight of the series of tapes 3.

111 14 designate two retarding-stops in the form of wheels or rollers on ashaft 15, which at its Iends is loosely fitted in vertically-slotted bearings 16, wherein it is free to rise and lower. These bearings are adjustably mounted on rods 17, secu red to brackets 18 on'crossrod 6, so that the distance of the wheels from the delivery end of the initially-acting tapes 1 may be increased or lessened, according to the stock being printed. These retardingwheels are directly above two of the tapes, and they rotate under the frictional contact therewith or with the interposed stock. The location ofthese wheels relatively to the discharge end of tapes 1 is controlled by the width' of the articles being printed. For instance, in printing bags the wheels are so located that the first one discharged from tapes 1 will at its forward longitudinal edge register against the lower edges of the retarding-wheels, whereupon the tapes 3 will be slightly advanced-say about one-half inchthe wheels 14 revolving to that extent, so that the forward edge of the next succeeding bag upon engaging the wheels will be prevented from overtaking the forward edge of the first bag. InV rthis way the bags are shingledou't on' the tapes in approximate fan fashion, the wheelslll and their shaft gradually rising under the increased thickness of the bags thereunder. The wheels insure sufficient friction between the tapes and the lowermost bag and betweenthe vseveral succeeding superposed bags toL maintain their relative positions in travel. The depth of the slots in the opposite bearings permits the retarding-wheels to accommodate themselves words, when the eXtent of the projection of ing the passage of each sheet and of the pile all the bags equals the width of one.

As the bags pass from the tapes 3 they go onto a lay-boy 20, having a vertically-disposed adjustable stop-gage 21. This lay-boy may be inclined, as shown in dotted lines, Fig. 4. As the forward edges of the bags contact one at a time with the stop-gage the bags are automatically piled with even edges one above the other. From the lay-boy, as well as from the outer ends of the tapes 3, the bags may be readily gathered up and removed by an attendant, care being taken, however, not to take up any bag any portion whereof is still beneath the retarding-wheels.

It will be noted that although the retardingwheels engage each bag as it is delivered from the press they cannot directly contact with the print on the face thereof, save in the case of the last bag fed from the press. This is due to the fact that before any one bag is moved forward sufficient to bring its print beneath the wheels the next succeeding bag is brought into position. Hence not only are the bags discharged onto the table without danger of smearing, but the means whereby they are retained in proper relation until arrested by the stop-gage will not come into Contact with the fresh ink of the print. As a bag contacts with the retarding-wheels the tapes are fed forward a short distance, which represents the extent to which such bag will protrude beyond the one next following. As the bags reach the stop-gage of the lay-boy they lose the shingling, and may then be removed in stacks with but little, if any, danger of smearing.

Although this invention has been found specially applicablein the printing of bags, owing to their size and the multieoloring of their print, yet it is obvious that it may be employed in the delivery of various kinds of stock.

I claim as my invention 1. A printing-press deliverer comprising a conveyer whereon the stock is designed to pile as it is discharged from the press, means for uniformly engaging each sheet as it falls on the conveyer for retarding the passage thereof and of the pile as a whole, and means for actuating the conveyer. l

2. A printing-press deliverer comprising a conveyer whereon the stock is designed to pile as it is discharged from the press, means within the length of the conveyer for retarding the passage of each sheet and of the pile as a whole, and means for actuating the conveyer.

3. A printing-press deliverer comprising a conveyer whereon the stock is designed to pile as it is discharged from the press, means within the length of the conveyer for retardas a whole, and means for actuating the conveyer as each additional sheet is added tothe pile.

4. A printing-press deliverer comprising a conveyer whereon the stock is designed to pile as it is discharged from the press, verticallymovable rotary wheels located above said conveyer intermediate the ends thereof and with which each sheet is designed to contact as it is discharged from the press, said wheels rising as the number of sheets thereunder increases, and means for intermittently advancing the conveyer and maintaining the relative arrangement of the sheets.

5. A printing-press deliverer comprising a conveyer vertically -movablc wheels above said conveyer for temporarily retarding the passage of stoel; thereon, a shaft for said wheels, vertically-slotted bearings for said shaft, and means for intermittently advancing said conveyer.

6. A printing-press deliverer comprising` a con veyer whereon the stock is designed to pile as it is discharged from the press, means located above the conveyer within the length thereof for temporarily retarding each sheet of stock as it contacts therewith, such means being free to rise as the extent of the pile thereunder increases, each sheet and the pile as a whole being uniformly maintained, and a lay-boy beyond the discharge end of the conveyer having a vertically-disposed stop-gage with which the sheets successively engage.

7. ln a printing-press deliverer, in combination, an initially-acting delivery-conveyer, a second conveyer onto which the former conveyer discharges and whereon the stock is designed to pile, rotary wheels above said seeond conveyer with which each sheet of stock engages as it is deposited on the pile thereof, means for permitting said wheels to rise and lower so as to conform to the thickness of the pile, means for intermittently advancing said conveyer, such pile moving therewith, and a lay-boy onto which said second conveyer discharges, said lay-boy having a stop-gage.

8. ln a printing-press deliverer, in combination, an initially-acting delivery-eonveyer, a second conveyer onto which the former conveyer discharges, rotary wheels above said second conveyer and designed to be actuated thereby, a shaft for said wheels, verticallyslotted bearings forsaid shaft, supports whereon said bearings are adjustably held, and a lay-boy onto which said second conveyer discharges, said lay-boy having a. stop-gage, as set forth.

9. In a printing-press deliverer, in combination, a series of initially-acting deliverytapes, a second series of tapes, rollers therefor, means intermittently.actuated for moving said second series of tapes, a. shaft extend- In testimony whereof I have signed this ed transversely of said tapes, vertically-slot'- speoifeation in the pr'esenoe of tWo subscrib- TO ted bearings 01' saiishaft, Wifieels onfthe lating Witnesses. y ter above saic secon series 0 tapes or teInf w s porarily retarding stock, and a lay-boy be- QHARLE GRANT HARRIS' neath and beyond said second series of tapes -Witnessesz having a vertically-'disposed stop-gage, as set lD.
