SHEET-FEEDING DEVICE.

Specification of Letters Patent.

Patented Aug. 25. 1914.

Application filed February 17, 1908. Serial No. 416,203.

T all whom it may concern Be it known that I, LEWIS E. MORRISON, a citizen of the United States of America, and

a resident of Newark, Essex county, New

Jersey, have invented certain new and useful Improvements in Sheet-Feedin Devices, of which the following is a specification.

This invention relates to sheet feeding mechanisms for feeding paper to the platen on a platen press, and the object of the invention is to provide a feed for handling sheets, envelops or other matter in such a manner as to enable the press to be run at greater speed, than when fed by hand, and also remove the dangers accompanying this latter method of feeding.

My feeding mechanism may, of course, be used on other machines than platen presses, but in this instance and in its preferred form it is shown applied to a so called job press. and one of the new, novel and useful features of this invention is, that it may be put on an ordinary platen press in a few minutes, and by means of no other tool but a wrench, and that no change or alteration of any kind is necessary in the construction of the press. Besides this obviously great advantage, my improved paper feed comprises a simple and convenient construction containing the necessary elements for register and adaptability for operation at different speed and for handling different sizes of paper. Further. While in this instance it is shown as receiving the single sheet or envelop from an operator, it will be seen that any suitable automatic separating mecha nism may be used for presenting the single sheet to this feeding device. After the sheet has been printed between the form and the platen, it may be removed by any suitable means.

Further objects and novel features of this invention will appear as the specification proceeds, setting forth the detailed construction, while reference is had to the accompanying drawings, in which- Figure 1 is a side elevation of a job press equipped with my improved paper feed, with parts left out. Fig. 2 is a detail perspective view of the feed proper, Fig. 3 is a detail view of a tape positioning means and Fig. 4 is a detail view of a corner of the platen.

Referring now to Fig. 1 the reference numeral 1 denotes the frame of an ordinary and well known type of job press; 2 is the platen and 3 the form. which latter is carried by the form carrying member l pivoted at 5 and oscillated by means of connecting rods Gonly one of which is shoyxnand gear 7 driven from pinion on main shaft 9. The platen is of the oscillating type, and I do not need to go into detail about the operation or construction of a press of this character, which is so well known in the art, further than to say. that the numeral ill indicates the platen locking cam found on all presses of this kind for locking the platen while the printing is being done.

Referring now more particularly to Fig.

2, it will be seen that my feeding device is carried between and by two brackets 11. ll which are fastened to the frame 1 by ordinary bolts 12, see Fig. 1. l pause here to point out that in Fig. 2 the platen is shown in its retracted position ready to receive the paper. and that in this figure I have shown all the parts in dotted lines. which do not constitute a part of my invention. bore the brackets ll I place a table 1 for receiving the pile of paper 14 which in this in stance is supposed to be separated by band and the single sheet 13 fed against a side registering guide It and then pushed onto the feed. The side guide is adjustable as shown and may be used for feeding to either side. Pivoted in the brackets is the upper tape shaft 17 and journalcd on this are the two swinging arms l8, 18. in the free ends of which the lower tape shaft in is journaled; tapes 20 pass over and around these two shafts. The shaft 17 passes through the one bracket 11 and carries on the outside thereof a gear .21. which is driven from gear 7 on the press through the gears 22. J3 and .24. the latter of these meshing with gear T. The gears '22, 23 and ll are carried on studs on the bracket 11. The single sheet is pushed out over the shaft 17 and onto the tapes '20 and by these latter is carried down and dropped on the platen at the proper time. \Vhile passing on the tapes the sheet is side registered by the guides l5. 25. carried by rods 21'. 26, which latter are ad- ]ustably fixed in posts 27, 27. The passage of the sheet from the tapes to the platen is timed by means of the stops 28 adiustably fixed on rockshaft 29. The stops rest on the cam roll shaft 19 and are held down by spring 30. At the proper moment, the stops are raised by the shaft 29 being rocked upwardly through the inst-rumentality of lever 31, link 32, bell crank 33 pivoted at 34, link 35 and lever 36, which latter is pivoted at 3? and carries a cam roll 38 cooperating with the platen locking cam 10. The rotary movement of the shaft 29 causes the stops 28 to be lifted out of the way of the sheet, which then passes out over the shaft 19 and drops on the platen, where its position is determined in the usual manner. The stripper fingers or platen grippers are not shown.

After the sheet is dropped on the platen, the latter moves down into printing position, consequently it is necessary to move the feed upward out of the way. This is accomplished in the following manner. Pivoted at 39 on the brackets 11 are two levers 40, one on either side, each of which cooperate with rollers 41, which latter are fastened to the platen as seen in Fig. 4. These two lovers 40 each carry a cam roll 42, which 00- acts with the cams 43 mounted on arms 18. The levers 40 rest constantly on the rollers 41 in the platen, hence any movement of the latter affects the position of the levers and thee in turn constantly support the feeding device through the rollers 42 and cams 43.

As shown in Fig. 2 the platen is in position to receive the paper from the tapes. Immediately after the paper reaches the stops 28 these latter are moved upby the 38 coacting with the low part of the platen locking cam 10, while the tapes, of course, rotate all the time. When the stops 23 are up the paper passes onto the platen, and the latter now moves downward to printing, position, and during this movement the rollers 41 lift. the levers 40 up and they in turn lift the feed as seen in Fig. 1, where the platen is shown in its highest position with the feed high enough to let the platen pass under it. The further movement of the platen simply causes the feed again to be lowered. After the printing is done, the platen again moves up, lifts the feed out of way, passes under it and is ready to receive the next sheet, which in the meantime has been placed on the tapes by the operator or a separating mechanism. Lever 31 is joined to the link 32 by a pin and slot connection, so that when the feed is swung up, the spring 30 is free to act to close the stops on shaft 19 in time to arrest the passage of the next sheet on the tapes.

The above is thought to clearly set forth the construction and operation of my invention. It will be noticed that the feeding mechanism is one unit as shown in full lines in Fig. 2, and that this unit is complete and may be readily placed on or removed from the press. The rollers 41 need in most instances never be removed from the platen.

Further, the mechanism may readily be made to fit any width of the press and can as readily be adjusted to suit any size sheet, as the stops and side guides are adjustable sideways. The brackets are joined by suitable rods or bars 44 and one other rod 45 is provided, which carry clips 46 for adjusting the position of the tapes. Only one of the clips is shown in Fig. 2 for the sake of clearness.

Fig. 3 shows a detail view of a clip, which is made of springy metal and is )rovided with spring positions 47 and 48 or grip ping the rod 45 and has depending Wings 49 for guiding the tape. By sliding these clips on the bar 45 the tapes are prevented from moving sideways after once being positioned.

Another feature which that the feed is operated by parts which belong to the press proper and that no connections or extra parts are added.

The construction may of course vary considerably within the scope of the claims and I do not wish to be limited to the precise form shown.
