To all whom it may concern: 7

Be it known that I, LEWIS L. RosnRs, a citizen of the United States, and resident of Orange, in the county of Franklinand State of Massachusetts, have invented certain new and useful Improvements in Sheet- Gages for Printing-Presses, Of\Vl1lCl1 the following is a specification.

The present invention relates to gages for printing presses and particularly to an endgage for a one-cylinder, two-revolution press in which the cylinder is movable up and down relatively to a horizontally reciprocating form and bed. In presses of this type, the individual sheets tobe printed are usually fed by hand on a feed table against an end-gage, the sheets usually being fed in a direction substantially parallel to the axis of the cylinder, and the end-gage being so disposed as to gage the front end of the sheet, that is, the edge of the sheet which is disposed at right angles to the direction of feed of the sheet. Such a gage is, therefore, termed herein an end-gage.' In a 7 press of this type, there are also provided suitable side gages which are designed to gage the side of the sheet, or that edge of the sheet which is parallel to the direction of feed and substantially at right angles to the edge of the sheet gaged by the endgage. v The principal object of the invention to provide a novel form of end-gage which is automatically movable to its working po sition and which is capable during its movement of so shifting the position of the sheet that it will be brought into contact witl all of the side gages, thereby producing perfect registry of the sheet.

A further object of the invention is to provide an end-gage, the parts of which are constructed in a novel manner to effect the automatic movement of the gage in a simple and effective manner. Furthermore, the

parts of the gage are so constructed as to render the gage reversible, that is, the gage may be used at either side of-the feed table by changing the position of certain parts of the gage to adapt the same for use at the other side of the press.

The invention is illustrated in the accomported thereby; Fig. 2 is a broken transverse section taken on the line22 of Fig. 1;

Fig. 3 is a planview of the end-gage; Fig. 4 is a side elevation of the construction shown in Fig. 8; and Fig. 5 is a horizontal section taken ,on the line 55 of Fig. 4, illustrating a detail of construction.

In the drawing, the letter A indicates a portion of the feed table of the press, the cylinder of whichis indicated at B. In the type of press illustrated, that is, a one-cylinder, two-revolution press, the cylinder'B moves bodily up and down, in the wellknown manner, to cooperate with a horizontally reciprocating form and bed. Mounted in the cylinder is the usual rock shaft C carrying a series'of grippers. D for gripping the edge of the sheet and carrying it around with the cylinder, inthe usual manner. The grippers D are actuated by the customary cam E carried by the end of the rock shaft and the sliding pin F actuated by the cam G. i

The side gages of the press are indicated at H, and so far as the present invention is concerned, it is immaterial what the specific construction of these gages is. As the improved end-gage may be used in combination with any type of side gage, whether.

the same be stationary or automatically movable, the specific construction of the gages H will not be described.

In the type of press herein illustrated,

the cylinder B moves up and down, as hereinbefore stated, and moves bodily with a frame I, in which is mounted the press-rod J running transversely across the press longitudinally of thecylinder. Relatively stationary upstanding portions K, of a suitable part of the press frame, carries a pressrod L, and the relative movement between the press-rod J and the pressrod L, caused by the vertical movement of the cylinder and frame I, is utilized for actuating the end-gage, as will hereinafter appear.

The end-gage itself comprises abase-plate 1 having several longitudinally disposed slots or openings 2, by means. of which the base-plate 1 may be secured to the feed table by means of bolts or other suitable fastening devices 3. The slots 2 permit bodily adjustment of the base-plate 1 on the feed table A, in an obvious manner.

The base-plate 1 has cast integral therewith,-

a couple of upstandingportions L servingas bearings for a cylindrical sleeve 5, which longitudinally slidable in openings 6 provided in said upstanding portions 4. The

sleeve 5 carries a collar 7 which is rigidly fastened to said sleeve by means of a set screw 8. The collar 7 carries an upstanding portion 9, which is centrally perforated to permit passage therethrough of a threaded adjusting rod 10, the purpose of which will be presently described. The collar 7 also carries a depending lug 11 having an opening therein through which a guide rigidly carried by the rear upstanding bearing portion 4, passes. In the present instance, this guide comprises a small cylindrical pin 12, on which the lug 11 is adapted to slide. By this construction, the sleeve 5 and collar 7 are absolutely held against turning move ments about the axis of the sleeve 5.

Passing through the sleeve 5 and co-aXially disposed with respect thereto is a stem 13, which carries, at its forward end, a block 14:, through which passes a gage-rod 15 disposed substantially at right angles to the stem 13. The gagerod 15 is adjustably mounted in the block 1st and may be shifted longitudinally of itself in said block. It is held in its adjusted position by means of a set screw 16. The adjusting rod 10, hereinbefore mentioned, has a horizontally disposed portion which passes through the upward extension 9 of the collar 7, as above stated, and a downwardly directed extremital portion 17, which is rigidly secured to the block 14. Adjusting and lock nuts 18 are threaded on the adjusting rod 10 and cooperate with the adjacent faces of the upstanding portion 9 to adjust the position of the rod 10 and to lock the same in adjusted position, in an obvious manner. When the rod 10 is so adjusted, it obviously adjusts the, position of the stem 13 in the sleeve 5, and when the rod 10 is locked to the upstanding portion 9, the stem 13 is in locked relation with the sleeve 5. Under these conditions, the sleeve 5, stem 13, collar 7, rod 10 and gage-rod 15 will all move bodily in unison in the upstanding bearing portions 14.

The gage-rod 15 carries, at one side of the block 14, the gage proper 19, which may be of any suitable construction, but preferably consists of a block 20 through which the gage-rod 10 passes, and to which it is adjustably secured by means of the set screw 21. The block 20 has secured thereto, the gage face 22'and the customary spring guard 23. The other end of the gage-rod 15 carries a block 24 adjustably secured to the gagerod by means of a set screw 25 and carrying a roller 26, which rolls along the surface of the feed table and supports the adjacent end of the gage-rod in a suiiiciently elevated position to assure the gage 19 at the opposite end thereof being held in close contact with the feed table to prevent accidental slipping of the sheets under said gage. In order to assure such contact of the gage with the feed table under varying conditions, there is preferably provided a vertically adj ustable connection between the block 2& and the roller 26, this connection as here shown comprising a stem 26 carrying the roller 26 and being adjustably secured to the block 24 within a vertical opening therein by means of a set-screw 26". It will be noted that the gage 19 and the roller block 24& may not only be adjusted to any position along the gage-rod, but they may be entirely removed and interchanged, in the manner hereinafter described.

The movement of the gage 19 to its working position is preferably effected as follows. The base-plate 1 of the gage pivotally carries a bell -crank lever 27 pivotally mounted on the base-plate bymeans of the removable screw 28. One arm of the bell-crank lever 27 engages behind the depending lug 11 of the sleeve 7, as best shown in Figs. 3 and 5, and the extremity of the other arm of the bell-crank lever lies adjacent the extremity of a guide 29, through which passes an actuating rod 30. When the rod 30 is moved longitudinally, it is obvious that the bellcrank lever will be swung around its pivot and the depending lug 11 moved to the dotted line position shown in Fig. 5. This effects a unitary movement of the collar 7, sleeve 5, rod 10 and stem 13, together with the gage-rod 15 and the gage proper 19. This movement is yieldingly resisted, however, by means of a coil spring 31 interposed between the forward upstanding portion l of the baseplate 1 and the collar 7. This spring serves to return the parts to their normal position after each actuation of the gage.

.The actuating rod 30 is pivotally connected at 32, (Fig. l), to a stem 33 which telescopes in'to the main actuating rod 3-1 and is adjustably held therein by means of the set screw 35. Referring particularly to Fig. 2, it will be seen that the main actuating rod 34- is pivotally connected at 36 to a sleeve 37 loosely mounted upon the pressrod L. The relatively movable press-rod J carries a sleeve 38, which is rigidly secured to its press-rod by means of a set screw 39. The collar 38 is provided with two for wardly projecting cheeks 39 between which passes a pin or roller 40, which engages in a slot 41 provided in a rearwardly projecting portion on the sleeve 37. By this construction, it is obvious that as the cylinder B and frame I, together with the movable press-rod J, move from the dotted line position shown in Fig. 2, to the full line position, the sleeve 37 will be rocked or shifted from its dotted line position shown in Fig. 2 to the full line position, and the actuating rod 34: will, therefore, be shifted longitudinally to the right in the drawings. This will produce a longitudinal movement of the actuating rod 30 in the guide 29 and a movement of the bellcran-k lever 27 to effect the movement of the gage, in the manner hereinbefore described.

In operation, a sheet is fed in. a direction substantially parallel to the axis of the cylinder toward the end-gage until the front edge of the sheet comes into contact with the gage face of the gage. As thecylinder rises, the parts of the end gage are actuated, as above described, so that the end-gage is shifted toits working position. It will be noted that the end-gage is so positioned as to engage either to one side. or the other of the central longitudinal axis of the sheet. As the gage, however, is adjustable with re spect to the gage-rod 15 and interchangeable with respect to the roller block 24, it may be made to engage with the sheet at any point along the front edge thereof. When it is made to engage with one side or the other of the front edge of the sheet, the sheet will not only be removed bodily backward, but one end thereof will be shifted in a lateral direction, so that if the side edge of the sheet is not engaging with all of the side gages, the movement of the end gage will shift the sheet into proper engagement with all of the side gages. In other words, as the sheet is moved by the end-gage, it has imparted thereto a slight turning move- .ment which has the effect of bringing the side edge of the sheet into engagement with all of the side gages. It will be found that there exists a certain point along the front edge of the sheet where the end-gage, if made to contact with the sheet at this point, will produce just enough turning movement of the sheet to bring the same into proper contact with the side gages.

The construction of the end-gage above described not only permits of numerous adjustments, but the entire gage is reversible, that is, it may be used at the other side of the food table when it is desired to feed the sheets in a direction opposite to the direc tion of feed indicated by the arrow, in Fig. 1. For this purpose, the bell-crank lever 27 is made reversible, so that it can be mounted at the other side of the base-plate 1., a second opening 42 being provided in the baseplate for this purpose. Fig. 5 shows, in

dotted lines, the position which the bell-.

crank lever will assume when pivotally mounted at 42. The actuating rod 30 will then, of course, be made to enter the guide 29 from the other side thereof, as further i11- dicated in dotted lines at 30 in Fig. 5,. When the position of the base-plate 1 is so transferred from one side of the feed table to the other, as indicated in dotted lines in Fig. 1, it will also be necessary to interchange the gage 19 and roller block 24, if it is still desirable to have the gage 1 9 engage with the edge of the sheet to the press side of the longitudinal center line of the sheet.

The actuating

sleeves

37 and 38 mounted on the press-rods .may be readily shifted to their new positions indicated in dotted lines in Fig. 1, or, if desired, additional sleeves may be provided at this side of the press and the

original sleeves

37 and 38 left undisturbed.

Although the improved end-gage has been illustrated and described in combine tion with a printing-press of the one-cylinder, two revelution type, it is obvious. that it may be as satisfactorily used on other types of presses, and on machines other than printing presses where a proper registry of the sheet is necessary. Furthermore, the gage need not necessarily beused as an endgage, as obviously it will functionin the 7 same manner if used in other relations.

Numerous modifications and changes may be made in the details of construction and operation without departing from the spirit or scope of the, invention, asdefined in the accompanying claims.
