Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed December 19,1905. Serial No- 292 521| It consists in combinations of parts and indetails of construction, which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a side view of a press having the attachment applied. Fig. 2 is a detail view of the feed-rolls, and Fig. 3 a detail view of Fi 4 is a detail showand 7 and platen.

It is the object of our invention to make an attachment for what are known as latenpresses, either having a slot made t rough the platen or a double platen whereby paper of an width u to the capacity of the ress ma e taken om a suitable'journale roll through the slot, thence over the face of the laten, and printed, and afterward being Hrawn ofl", cut, and delivered upon a receiving-table.

We have onlyshown so much of the press in the drawings as will enable our attachment to be intelligently understood.

A is a roll of paper of suitable size, the shaft of the drum being journaled in the frame 2, which is secured to the press for that purpose and in rear of the platen 3.

The platen has a slot or channel made through it, as shown at 4, of sufficient width to allow the paper to pass through this slot.

5 is a guide-roller at the u per end of the slot, over which the paper rom the roll A passes, thence through the slot or channel 4 and over the guide-roll 6 at the lower end of the slot. From this point the paper passes up across the face of the platen, thence over the roll 7 and between this roll 7 and the,

sleeves or rolls 8, which are adjustable upon a journaled shaft 9. The rolls 8 are slidable upon their shaft 9 and are so fixed that they will press upon the edges of the sheet which is passing between them and the roll 7. The printed matter passes between the rolls 8, not

eing pressed upon by them. It will be seen that b movin these rolls outward or inward t ey may e adjusted to suit any width of aper which is to be taken from the roll an printed.

Upon the end of the shaft of the roll 7 is a loosely-mounted gear-wheel 10, and this gear-wheelengages a curved rack 11, which is carried upon a similarl -curved support 12. Upon the outer end of t e shaft of the gearw eel 10 is a ratchet-wheel 13, and this is engaged by pawls, as at 14, the object of which is to prevent the rotation of the roller 7 While the platen is moving in one direction and engaging with the ratchet-wheel so as to revolve the roller when moving in the opposite direction.

The action will then be as follows: When the platen moves to the rear, the engagement oft e gear-wheel 10 with the rack 11 will cause the roller 7 and the contacting rolls 8 to revolve, thus drawing the paper of! of the roll A, over the guide-rollers 5 and 6, and through the slot 4 inthe laten, thence over the face of the platen and etween the rollers 7 and 8. When the platen moves forward, the pawls will move freely ovefthe ratchetwheel and the gear-wheel 10 will turn loosel on the shaft of the roller 7 and will not ad vance the paper during this movement, which carries the platen to the point where the paper, which extends across its face, is impressed and printed in the usual manner for this class of machines. When the platen again moves back, the paper will then be advanced by the action of the pawl on the rack, the turmng of the rolls 7 and 8, and the printed portion of the paper will be drawn off and assed between cutting-shears to be hereina ter described.

As previously described, the rolls 8 may be adjusted to press upon the edges of the paper whatever may be its width, and thus insure its advancing at each backward movement of the platen and without any pressure being brought upon the printed portion.

The length of the paper to be printed will be regulated by the position of the curved rack 1 1. This rack is fixed upon its support 12 by locking-screws 11 so that it may be moved forward or back. Thus if moved to such a point that the gear-wheel will engage it at once when the platen commences to move back it will be understood that the greatest amount of paper will be drawn through the feed apparatus; but if a shorter amount is desired the rack is moved upon the support 12, so that the pinion 10 will not engage with the rack until the platen has moved over a considerable portion of the distance in its backward movement, and the paper willnot commence to move over the platen until such engagement of the pinion with the rack takes place.

1 5 represents cutting-blades normal] separated by springs 16. These blades ave a 7 length equal to the width of the apparatus and are'actuated by coming in contact with an extension 2 of the frame 2, the carrier of the blades 15 being attached to and carried with the platen, and when the platen returns to its rearmost position the blades contact with the extension 2 and are thus closed and the paper out off. When thus cut, it drops upon the table or sup ort 17, suitably located beneath the disc arge portion of the ap aratus.

11 order to insure the proper movement of the aper, we have shown guide-arms 18 extending in line with the feed-rolls '8 and across the face of the platen and adjustable in unison with these rolls, so that whatever width of pap er may be fed between the rolls 7 and 8 the guides '18 will be adjusted to correspond with the rolls 8, so that the edges of the paper willpass between the guides and the platen and be properly delivered to pass over the rollers. I

Having thus described our invention, what we claim, and desire to secure by'Letters Patent, is

7 1. The combination with a platen-press of a roll-paper support, mechanism by which a portion of the paper is advanced across the ace of the platen at each oscillation thereof, and mechanism by which the printed portion is subsequentl severedfrom the roll and delivered, said ast-named mechanism being carried withjthe platenand the severing de vices thereof being actuated by contact with a sto at the termination of the rearward movement of the platen.

2. The combination with'a press having a reciprocating platen of a roll-paper su port, a

platen with a slot or channel throug which the paper passes before passing across the face ofthe platen, mechanism by which the paper is drawn through said slot and across the face of the'platen during the backward movementof said platen, said paper remaining stationa during the forward movement and impression, and cutters b which the paper is severed and. discharge at the culmination of the backward movement.
