To all whom it may concern:

Be it known that I, JOSEPH KLEIDMANN, 1: sobject of the Czar of Russia, and resident oi the city of New York, in the county of New York and State of New York, have inand useful Improvements in Feeding-Machine Attachments for Printing-Presses, of which the following is a speci fication.

The present invention relates to improvements in feeding machine attachments for printing presses, and is adapted to be attached to any well known form of feeding machine for printing presses, ruling machines and the like. More particularly, the invention relates to means for registering the sheets of paper as the same are fed on the feedingfisable to the press cylinder of the printing presses.

The registering devices, heretofore in use, may be divided into two general classes, that is, first, such devices which push the sheet of paper into its proper position, and, second, devices which'pul the sheet into its iroper place. The first class is objectionable imthe reason that the sheet is very often, due to the adhesion of the paper to the feeding board waved or buckled, and, when consequently released from the re istering apparatus, springs sidewisc, whereby it is brou ht out of its registering position. These eviccs, heretofore in use, which pull thesheet into its registering Iposition, are defective for the reason that w ien the re istering apparatus is about to release the s ieet of paper to be fed. into the printing press, the movable part of the registering apparatus very often pulls the sheet out of its registering position.

It is now the object of the resent invention to obviate the aforesaid efects; and to that'end the invention consists in the combination, with a. printing press and mechanisms automatically supydying the aper to said press, of a registering device, t 1e sheet gri ping part-of which is slidably and resiliently supported by ti 1c swinging portion of the apparat'us, and is caused by suitable means to inove in a substantially vertical line when disengaging the sheet, wliorel'iythe same is pt in its registc'rin osition.

Other ob'octs wil 1e apparent from a reading of t e specification and an examination of the drawings, forming part of the present application.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a paper feeding a paratus, having the attachment, forming tie subject matter of the present ap 11ication, attached thereto, 2 a top-plan F1 view of about one-half of the attachment,

Fig. 3 is a side elevation of the re istering device, showing the position of the sheet grippin part, when about to engage the sheet 0 paper, Fig. 4 is a similar view of the apparatus, showing the registering device in a position, whereby the sheet of paper is engaged and drawn into the registeringpositiou, and Fig. 5 is asiinilar view, the sieet gripping part moving upward, whereby the sheet is disengaged. Fig. 6 is a top View of the registering device, while Fig. 7 is a perspective view of a detail of construction.

It it ill be observed that in Figs. 1 and 2 of the drawings, only those parts of the feeding machine are shown, which are necessary to understand the operation of the registering apparatus, and as shown in Fig. 2 of tho. drawings, about one-half of the operating mechanism of the registering device is illustratcd, it being understood that the same arts and devices are applied on the other iiall of the :ittaclnncnt.

In the drawings, 1 designates one of a pair of the side frames of the feeding machine, connected to the side frame 2 of the printing press. -T he stack of paper is indicated in the drawin s at 3 and is supported by a table 4, prefera )ly automatically raised as the sheets are fed from the same.

T he sheets are brought by the feedin mechanism unto a forwardly bcnt lip 6 am thus u .101! the feed table 7, wherefroni they are fe unto the press cylinder 8, suitably geared with the main shaft 9 of the feeding apparatus, which main shaft governs the motion of the feeding mechanism 5 and of the registering apparatus, hereinafter to be described.

- Attention is called to the manna a registering device for the paper is arranged on each side of'the machine and'obvioiislv one i of those devices is used when one side (if the paper is being printed, while the other is made use of when printing the reverse side of g the sheets. In describing theselegistering devices, it isthought that only' one of the same is to be considered, the other being which rests on the feeding table 7, and the respectively.

t er

leg 12, arranged at right angles to the leg 11, serves as a guide for the sheets. Dbviously the leg 12 is arranged at right angles to the main shaft 9 of the ap aratus and thus parallel to the side edges oi the sheets, moving onthe feed table 7. The frame 10 is secured to a substantially square block 13 by means of screws 14, which square block is ada ted to reciprocate inguiding slots 15 of the eed table 7, which guiding slots run parallel with the axis of the press cylinder 8. The frame 10 supports the re istering apparatus, here inafter to be descri bed.

The registering apparatus, as will be seen, moves to and fro the center of the feed table, and for that purpose the square block 13 is adjustably mounted upon a rod 16, arranged parallel to the axis of the press cylinder, and engaged by a bellcrank 17, fulcrumed at 18 to the upper side of the table; the free end of the bellcrank is engaged by a connecting rod 19, which in turn is pivotally'connected to the arm 20 of a two-armed lever 21, ivoted to the frame of the machine at 22. he free end of the arm 23 of this lever carries a roller 24, engaging a cam 25, arranged on the main shaft 9 of the feeding a paratu's, and controlling the movement 0 the registering device. To impart the reciproc ting motion of the rod 16 to the r ten (i evic'e arranged on the other side 0 the ta lo, a two-armed lever'26 is mounted on the feed table 7 and connected by means of connecting rods 27 and 28 with the

alternating rods

16 and 16,

The registering device comprises fur more the register arm 29 pivoted to a bracket 30, arranged on the vertical leg 12 of thesupport or frame 1.0.1 The free end of this arm 29 carries slidabl'. arranged thereon a block 31, adapted 'to slide in the plane of the arm 29 in a direction at right angles to the s indle 32 updn which the arm 29 oscillates. or this purpose the 'block 31 is bifurcated at 33 and engages the arm 29, which is provided at its lower portion with a slot 34 e aged by a-pin 35, arranged on the bifurca-t'e portion of the block 31. To more safel guide the block 31 the latter is provide with a hole 36 in its upper extension 37, and engaged by a s indle- 38,, secured to the arm 29 and provide with a head 39, between which and the extension 37 j of the block 81 is arranged a helical spring 40, normally keeping the block 31 in its inner position upon the arm 29. A roller 41, having preferably a rnugh covering, such as rubber, is arranged on t e block 31 on a spindle 42,

whereby the roller ma revolve in the direction of the travel of t e sheets. This roller 41 may be kept in contact with the sheet 43, resting on the leg 11 of the frame, by means of a spring 44, en aging the arm .29 at 45 and wound around t e spindle 32, upon which the arm 29 oscillates. The arm 29 is furthermore provided near to its front end with a hole 46, in which is arranged a pin 47, .carried b a spring 48, arranged on the arm 29, whereliy the pin is forcedto protrude through said opening, but at the same time is adapted to be ressed inwardly by the block 49, arranged on the table 7 of the ap aratus; This block 49 is adjustably arrange 'in the slot 15 of the table and is provided with a' sto 50 in the path of the block Sfl, carried by t e arm "29 of the ap aratus. The pin 47 protrudes through the ole 46 of the lever 29, and, obvionsly, in the backward movement the ap- Earatus would be prevented in its movement y the block 4'9, arranged in the path of the pin, were it not for the tapering oove 51 in this block, in which the pin s des and is pressed against the tension of the sprin out-' wardly, so that it comes to contact wit the inner side of the block.

The operation of the registerin device is as follows: First the block 13 and thus the 'moving part of the re ister is'arranged in its proper osition upon t 6 rod 16, corresponde' width of the sheets to be fed; then the block 49 is moved in the slot and secured against movement at a place where it is intended to disengage the sheet of paper, that is where the sheet is 111 its register ng position. When the registering device is in its outermost position the pin47 rests upon the inclined upper surface'52 of the bloc 49, as will be hereinafter described; thereby the roller 41 is kept at 'a certain distance from the leg 1 l of the frame 10. I As the registering device new moves toward the center of the table-to engage a sheet, thesheet will be brought,to ay-. a ainst theviertical leg 12 of the frame 10 an thusbe in a position to be gripped. The registering device having moved forward, the roller is caused to engage the sheet of page! by the spring 44, as soon as the pin. is 'sen aged withthe inclined surface 52, or in o't or words when the pin arrivesat the front ed e of the block 49. It is obvious that the re e1'41hand the leg -11 of the frame 10 form coacting grip ing jaws, engaging the sheet. Thecam 25 t en causes the registering ap aratus to move outward fremt epenter o the table and pull thus the sheet in a predetermined registering position. The tapering groove 51'allows the registeringlapparatus to move backward, by pressing t efpin 47 inward! so that itemtacts with the inner side 0 the wall of the block 49. As soon as the forked end 33 of block 31 comes in contact with the stop 50.,

or in other'words, into the position in which the sheet should be releas d, the roller 41 .moves upward by sliding upon the curved surface of the stop 50, whereby the sheet is disengaged and allowed to pass unto the press cylinder of the printing press.

It will be seen that, since t e block 31 is slidably arranged on the arm 29,- and although the arm 29 moves further outward, the block 31 will be allowed to stop for a time and then move for a predetermined time in a vertical line upwards, or in other words, will move with a speed equal to zero in the direction of travel of the registering device for a predetermined time, by reason of the stop 50, whereby the sheet of paper is properly disengaged in its registering position. The arm 29 swings further upward, whereby the pin 47 engages the taperingsurface 52. The cam 25 forces the reci n'ocating rod 16 then again toward the center of the table to carry the registeringdevice forward in the position to engage the next sheet of paper.

It is obvious that the apparatus can be rdapted to operate on paper of different widths by adjusting the movable element and the stationary element of the same on the reciprocating rod 16 and in the slot 15, respectively. It is obvious furthermore that various minor changes may be made in the construction of the device and al'scin the arrangement of several parts without departing from the spirit and scope of the present invention.
