Specification of Letters Patent.

Patented Oct. 30,1906.

Original application filed July 6, 1905, Serial No. 268,453; Divided and this application filed Julie 8, 1906. Serial No. 820,800-

To all whom it may concern:

zen of the United States, residing at Lake Fores't, in the county of Lake and State of; Illinois, have invented certain new and use. ful Improvements in Sheet-Delivery Appara-E tus, of which the following is a specification.

This invention relates to sheet-delivery apparatus adapted for use in connection with such devices as printing and folding ma-' chines.

tain improvements in the construction of such apparatus, more articularl with respect to the provision 0 various a justments by means of which uniform and reliable operation can be obtained with sheets of various sizes.

I will describe my invention in connection with the accompanying drawings, which show the preferred embodiment thereof, and in Which Figure 1 is a central section of a foldingmachine provided with myimproved delivery apparatus. Fig. 2 is a transverse section thereof. Fig. 3 is a section on line 3 3 of Fig. 2, and Fi 4 is an elevation of a portion of one end of the machine.

Although I have shown my improved delivery apparatus in connection with a foldingmachine, I wish it understood that it is equally well adapted for use in connection with machines of different characteras for instance, printing-machines.

The machine consists of two side plates A A, on the upper edge of which is mounted a held in roper position by adjustable'guides N. A fiinged weight b bears on the top of the sheet-pile. Directly under this weight and mounted in bearings in. the -side frames of the machine I area separator-roll C and an idler-roll C, the

former of which is rotated by any suitable mechanism to successively buckle the sheets of the pile between it and the idler-roll C. Directly below these rolls are pressing and passing rolls D and D, rotatable in bearings A A, and directly below these rolls is another pair of pressing and assing rolls D D which receive the sheet fo ded by the rolls D D and pass it downward into the justable stop E mouth of a guide E. This guide has an adtherein, which limits the movement of the sheet into the guide, buckles the sheet, and causes it to Be it known that I, ALBERT B. DICK, a citidirectly below the The object of the inventlon is to eflect oer-i or printing machine.

ass out between the roll D and a delivery-ro ll d, arranged adjacent to the pressing and passing rollD- A guide (1 is mounted u on a shaft d and extends in proximity to tli of the rolls D and d and is arranged to guide the forward edge of a sheet passing between e point of contact those rolls downward and to be moved on its I supporting-shaft by the sheet to permit the sheet to pass beyond the guide.

end of the reciprocating guide (1 is a guide-roll d. This roll preferably has peripheral grooves therein, into which lips on the end of the reciprocating guide d can enter when the end of the guide is moved downward by a sheet. These parts of the machine are described in detail in a companion application, Serial No. 268,453, of which this application is a division, this application being limited to the delivery apparatus, which may be used with any folding Mounted'vertically directly below the delivery-roll d is a stripper-plate F, the upper edge of which terminates either in contact with or in close proximity to the roll (1.

. Mounted Formed on this plate are two vertical guides f and between these guides is a slot f The supporting-frame G for the delivery-tray has ways therein, into which the guides df extend,

and between these ways is a threa ed opening'adapted to v hand-nut f which extends, through the groove f in the stripper-plate F. In this way the frame G and theparts of the deliverytray carried thereby can be moved to any desired position of vertical adjustment and then secured in that position by tightening the hand-nut f Pivot'ally mounted in ears g, formed on frame G, are the ways H H of the delivery-tray, the rear ends of which extend through openings h in the stripperplate F and are turned upwardly. Mounted for rotation in ears g and g formed on the frame G, is a shaft 9 on which is mounted a forwarding-roll g", lying between theways receive the threaded "end of a H H. On the end of shaft 9' beyond the side plate A is a spiral gear h,

meshing with'a similar gear 79, splined. upon a shaft 'h its lower end this shaft is journaled in bearthe frame G and the ening the nut j these bearings. At its upper-end shaft 7L3 has secured thereto a spiral gear 6, lying between the arms of a yoke 71, secured on the side frame A, which arms have bearings formed therein for the shaft h meshes with a similar gear 47, secured on a stub-shaft i carrying a gear t, which meshes with a similar gear on one of the shafts of the machine. It will thus be seen that the driving connection to the forwarding-roll g is maintained in all positions of adjustment of parts carried thereby, the only effect of such adjustment, so far as this connection is concerned, being to move the spiral gear 7L2, which is splined on shaft h axially of that shaft. The periphery of the forwarding-roll 9 extends slightly above the surface of the ways H H, so as to forward on the same the folded sheets fed thereon.

Formed in each of the frame members A A is an arc-shaped slot J, curved about the pivotal axis of the ways H H as a center, and within these slots operates a cross-rod one end of which is provided with a head 3 and the other end of which is threaded and provided with a hand-nut P. This rod extends through slots formed in brackets j, each of which is secured to the under side of one of the ways H. The outer end of the ways can thus be moved to any desired position by loosening the hand-nut 3' and moving the rod j, which supports that end of the ways, to any position between the ends of the slots J, in which position the rod may be held by tight- The outer end of the delivery-tray, as well as the inner end, can thus be adjusted as desired in order to obtain the position and inclination of the ways H which will give the best results.

Mounted to slide back and forth upon the ways H is a block K, which maintains the sheets in proper position upon the ways and is moved backward by the accumulation of the sheets between it and the stripper-plate F.

In the operation of the machine the sheets which have been folded or otherwise acted upon are passed between the rolls d and d and down alongside the stripper-plate F, which in addition to guiding the sheets prevents them from being carried around by the roll d. As the sheets accumulate upon the ways H they are moved along by the forwarding-roll 9 the periphery of which is fluted or corrugated, but are always maintained in proper position by the sliding block K. The position of the end of the ways adjacent to the roll d can be readily adjusted toward and from the roll d. The best results are obtained when the delivery-tray is in such position that when the lower edge of the sheet reaches the ways H .the upper edge has just passed below the line of engagement of the rolls d and (i so that when the downward movement of the sheet is arrested by the ways the roll (P will carry the upper The spiral gear i ed e of the sheet around to the side of that roll away from the roll (1. This provides a narrow V-shaped space into which the forward edge of the next sheet brought around by roll d can enter. By means of the adustment provided for the end of the deliverytray adjacent to roll (1 this position can be obtained for sheets varying considerably in size. The forwarding of the sheets along the delivery-tray is effected more or less readily, dependent upon the character of the sheets themselves, and by adjusting the inclination. of the tray this forwarding of the sheets can be retarded or assisted. Since provision is made for the adjustment of both the inner and the outer ends of the tray, such inclination as will give the best results can be readily obtained.

Having now described my invention, What I claim as new therein, and desire to secure by Letters Patent, is as follows:

1. In sheet-delivery apparatus, the combination of a delivery-roll, a stripper-plate coacting therewith, a delivery-tray one end of which enters an opening in said stripperplate, means for adjusting the end of said tray adjacent to said delivery-roll toward and away from the roll, and means for locking the tray in any adjusted position, substantially as set forth.
