PRINTING. PRESS.

To all whom it may concern.'

Be it known thatl, EDWARD CHESLTIR'E,

a citizen of the United States, residing at Presses, of. which the following isaspecifii' cation.

This invention relates to a printlng press, and more particularly to means for position@ receives an impression.

ing and registering sheet material, before it.

One object of the invent-ion is to provide.

a simple, suitable and readily adjustable side guide which is particularly adapted' to accurately register sheets ofinaterial being fed, and particularly automaticallyfed to a vertical cylinder j ob press, such as that disclosed in' my copending application, Seria-l No. 929,976, filed October 11, 1919. A

Another object is to"accuratelyfdetermine the position of the pile on the stocktable as a result of the adjusted position of a side register which registers the' sheet with respect to the printing form.

Another object is -to make ,it possible to register interchangeably on either side of the press, particularly in the type of press hereinabove referred to. A

Another object is to provide a simple and eflicient side register for'printing presses adapted to meet the various requirements for successful commercial operation. y

The various novel features of my invent1on will vbe apparent from the following descriptionanddrawin s and will be'particularlyl pointed out in t e appended claims. 'I ln's invention' 1s illustrated preferably in "connection withithety-pe of printing press shown in my copending application, Serial No. 329,976, filed October 11, 1919, said' printing press, among other things, including 'a main frame 10 1n which the printing forni is reciprocated in a Vvertical plane, as' also 1s the cylinder, said printing' form andl cylinder moving 'in opposite senses for reasnns nientionedin said copending appli-y from the main frame is cation. Extendin an arm .11, to which is' pivotally connected at 12a stock table frame 13 carrying a stock table 14, on which the sheet material to be fed tothe press is placed. It-will be vunderstood that the frame 15, in which the.cy1in-' der 4'16 is rotatably mounted, isreciprocated vertically, said frame 15 being actuated -by f any suitable mechanism, which may be connected thereto at theV point 17. A transfer table 18 at opposite sides is secured to arms 19, which in turn are piviotally connected at 20 to the cylinder frame 15. Accordingly,

as the cylinder frame moves upwardly. and downwardly, so does the transfer table;

' Thisl particular invention has to do prima rily with side registering the sheets of material which' are to receive an impression, the accurate positioning of the stock on the table with reference to the side register means after the latter has been'accurately positioned, and the relation between the side register-means, transfer table and the stock table.-

With these points in view,'it will be noted that secured to the cylinder frame 15 at opposite sides of the cylinder are supporting brackets 21, in each of which is mounted a pin 22. Upon each of sai'dpins 22 is pivotally supported a carrier arm 23 normally pressed upwardly by an associated torsion spring 24, as shown in Figures 1 and 3, the spring 24 being connected to the arm 23 and pin 22. The tension of the sprmg in 'groove' 27 (see Figures 3 and 4) .in the earrier arm 23, and is clamped 1n adjusted posil tion by an overlying plate 28 and screw 29.

which passes through the plate and into the arm 23. Preferably, and as shown 1n F1 ures 1 and 2, thebar 26 has an integr-al y formed arm 27 extending at right angles thereto and provided with a tapped opening 68 into which is threaded for rotatlon a cupshaped member 69, which may be secured in any adjusted osition by a nut 30. Saul cup-shaped mem er has an opening there-- through for the reception of a rotatably and longitudinally movable pin 31 havmg an enlarged head 32 with an aperture therethrough for slidably receiving the side register bar 33.l The cup member 69 hasfa diametrically extending slot 34 therein 'for accurately positioning the bar 33 with'I -respect to the level ofthe transfertable for maintaining the` adjusted posltlon, even though the bar is removed from the groove,

in a manner to be referred to later. In thisl connection a spring 35 is coiled around the outer end of thepin 31 and is interposed between one end of the member 69 and a washer 36 secured to one end of the pin 31,

.whereby the bar 33 is yieldably clamped or retained in the slot 34 of the member 69. If, however, it is desired to rotate the register bar 33 from its normal functioning position, fo-r example, when it is desired to remove the transfer table, the same may be accomplishedby forcing the bar 33 laterally (using a screw driver fulcrumed in an adjacent notch 70), compressing the spring 35 unt-il the bar 33 is beyondH the confines of the slot 34, whereupon the bar may be rotated the desired amount. However, the position of the slot remains unaltered. When the bar 33 is rotated back to its original position, it will re-enter the slot 34 to occupy the positionit had prior to its withdrawal, without any variations with respect to its position relative to the upper surface of the transfer table. With the portion of the `head 32 locatedin the cupportion of member 69 and the bar 33 in the slot 34 of member 69, the bar 33 is clamped sccurely vby the action' of the spring 35. One

end of the register bar 33 is provided with a tapped portion .for the reception of an adjustable stop member 37 and terminates in a pin 38, said 'stop member 37 and its pin 38 during the actlon of registering passing into one of a plurality of grooves 39 in the transfer table. The stop member 37 is threaded into the bar 33 for making the final minor or delicate adjustment inconnection with registering the sheet material,

and is held in adjusted position by a pin cured to the bar by any suitable means 42. Y

In connection with the operation of the i sidel register mechanism, after make-ready it becomes necessary to locate or side register the sheet with reference to the printing form. In this connection a sheet of paper 43 is placed on the transfer table 18, usually by hand, in approximate location and the adjustable side guideor bar 33 with its attached parts is adjusted to stop the sheet (when the cylinder is at the lower end of its travel) for a trial impression. Error in the location as revealed by the trial impression, maybe corrected by the further adjustment of the side register, that is, by moving the graduated bar 26, which is connected to the side bar 3.3, longitudinally in the groove 27 of the carrier arm 23, whereupon the graduated bar 26 and its associated parts will be again clamped in position by the screw 29. It may be necessary to make a finer adjustment. This may be doneby rotating the stop button 37 one way or the other, whereupon it will be held in adjusted position by the spring-pressed pin 40. It will be understoodkv that the bar 33 is adjustable with respect to the graduated bar 26, and also with respect to the transfer table 18, so that the stop button 37 and pin 38 may` occupy any one of the grooves 39 in the transfer table 18, so that the stop button 37 will be approximately in the middle of the side edge of any sheet used. As soon as the sheet is definitelyu located on the transfer table, the indication on the slidably adjustable graduated bar 26 will be observed, and this indicates and determines the location of the stock pile 44 on the stock table 14, as it is now only necessary to adjust the stock guide 45 and its attached block 46 to 'the same reading on the scale 47 as indicated by the scale on the. graduated bar 26. Accordingly, stock may then be placed against the guide 45 and the other threeguides 48, 49 and 50 adjust to retain the stock pile in contact with the pile guide 45. A sheet now taken from the stock pile by automatic means and deposited on the transfer table will be off side register by a predetermined amount, as indicated at 51. The dipping motion of the transfer table from the position shown in Figure 3 to the position shown in Figure 4, it being understood that the transfer table is dipped by any suitable mechanism through a connection, as at 52, first registers the sheet against the cylinder grippers 71 and then a sidewise movement of the transfer table as described in my said copending application) carries .the sheet .against the side regisllo . in Figure 3, to its functioning position, as

' 'shown in Figure 4, by a cam 52 cooperating t with a member 53 secured to the carrier.l Assoon as thesheet has reached its limit of sidewise movement, it is seized by the A bracket 21;

cylinder grippers 71, and as it is withdrawn from the transfer table, the side register bar 33 moves upwardly out of engagement with the sheet, under the intluenceiof the coiled spring 24, the upward movement of the side registering'mechanism being limited by a projection 54 on the carrier member 23 passing int engagement with a stop on the It is important that the l'side register bar be raised before the paper is drawn from the transfer table by the cylinder, because the side register stop button 37 would soon become marked and rendered inaccurate. The pin 38 serves the function of carrying the sheet down with it at .the instant of side registering and insures `perfeet register by bringing the sheet into correct alignment at the required time, thepin being especially valuable in case that the I sheet is bent or curly.

If desired to have the sheets register at the opposite side of the press, the same may be done by removing the graduated'slide bar 26 and its attached parts, from the carrier arm 23 at the left-hand side and placed in position in Vthe carrier arm 23 at the rightlhand side of the machine, in which event the guide: 48 on the stock table would be the pilot guide. I p

' A modification of the side register mechanism is shown 'in Figures 6 and 7, in which the side register bar 56 has secured at its outer end a fixed stop butt-on 57 and pin58, the minor or line adiustmentbelng made by adjusting the pivotally mounted bar carrier 59 with respect'to the graduated laterally slidable bar 60. through the actuation of a nut 61 threaded on a stud 62, around which is coiled a spring 63 located intermediate the bar 60 and an arm of the bar carrier 59. The side register bar 56 is adj ustably held in position by means of a clamp 64 associated with the bar carrier 59, which is pivotally connected at 65 to the graduated slide har 60. The other parts are the same as that shown in the main figures of the drawing which disclose the preferred form.

It is apparent that there may be various other modifications of the invention as here- Vin particularly shown and described, and it in a relative movement cooperating with said transfer table for' registering a sheet of material on said transfer table. i
