One object ofv the-inv ention is to provide simple,..eiiicientand.reliable side guide meansv Y which may be used interchangeahlyfor reg-- istermg purposes at either side of the press.

Another object is to provide. side register 1 means having a member. for preventing 1Duckling during theregistering operation of a fed sheet.

Another object is to provide a side guide mechanisnifor printing presses adapted tof meet the various reqnirements for Successful commercial nsef Y. f y

n Referring to the figures of the drawings, it will he noted tha-t lhave disclosed my invention in connection w ith a vertical Ytype of printing press, including the main' frame l0 Awhich supports all of the other parts of the press. It might bestated that this printing'press.includes a type carrying bed and wcylinder, both -of which have simultan'con's verticall movementsin opposite directions, as disclosed in the Cheshire application, Seria-l1 No... 329,976, tiled October 11, 1919, 'theV cylinder being carried in a frame including frame members'y l2V and 13 The side guide mechanism Vincludes a shaft 11 which is supported by Vsa-id cylinder frame memioersl2 andv 13'. the left end of the shaft a sleeve lllwhich is Vsnrrouv 1.51 mounted in the frame bushing 15 has a shoulder More speciiicall, 11 is mounted in, nded by a bushing member l2.

are twoarms 27 d located near opfh'esef afrms 2 at ted. by a rod 21T gage 28y so is given: a lateral.v 2S likewise willhe given a lateral movement and when the shaft is given a rotary movement the side guide 28 will be given an oscillatory or dipping movement in a manner such that it will side register a sheet which is being fed progressively to the impression means of the press. The member 27 is adjust-ably clamped on the cross-bar 27 and provided with a tightening thumbV screw 29 whereby the side guide 28 may be secured to the bar 27 in any adjusted position.

In connection with setting the side guide member 28 it may be given a general adjustment or setting whereby the thumb screw 29 will be tightened for fixing the side guide 28 on the bar 27. The side guide member 28 may then be given a micrometer adjustment by the sleeve is moved to the right for turning the knurled head 30 which is pinned to the micrometer screw 24, thereby causing the shaft 11 as a whole, together with the arms 27, rod 27 and side guide member 28, to be adjusted endwise for giving such register member 28 its final setting.

A spring31 is mounted in a pocket 32 of the sleeve member 14 and interposed between a shoulder 33 of the sleeve and one end of the shaft 11 for taking up any lost motion between the threaded parts of the micrometer screw 24 and the shaft 11.

A coiled springr35 surrounding the sleeve 14 is interposed between andV engages the collar 22 and the washer 19 so that when positioning the side register member 28 for side registering a sheet of material, the spring 35v will be compressed so that when the sleeve 14 and the shaft 11 are released the spring 35 -will return the parts to their normal positions. Secured to the inner end of the sleeve 14 is a collar 36 between which andV thewasher 2O is mounted a coiled spring 37 which surrounds the right-hand end of the sleeve 14. vSuch coiled spring 37 is not compressed during the right-hand movement of the shaft 11, but i1; is compressed when the side register member 28 is used for registering a sheet at the opposite side of the'press and the shaft 1 1 is given a left-V Vhand movement from its normal position shown in Figure 3, the compression in said coiled spring 37 then being used for returning the shaft 11 and accordingly the side register member 28 to their normal positions, as shown in Figure 3.

Referring to Figure 1 of the drawings, it will be noted that secured to the frame 10 is a control member 38 having a guide groove 39 set atan angle for the reception of the roller 23 so that as the cylinder frame members 12 and13 are moved downwardly, carrying the shaft 11 and all of its associated parts, the roller 23 will enter the guideway 39 and cause the shaft 11 to be moved to the right for side registering a sheet of material at one side of the machine` During this movement the left-hand coiled spring 35 will be pressed, and as soon as the cylinder frame members 12 and 13 with the shaft 11 are again moved in an upward direction, the spring 35 will return the shaft 11 to its normal position, as shown in Figures 1 and 3. If it is desired to side register a sheet of material from the opposite side of the press, the same may be done by loosening the thumb screw 29 and shifting the side gauge member to the right, as shown in dotted lines in Figures 1 and 2, where said member may be secured by tightening the thumb screw, and by swinging the control member 38 into the dotted line position shown in Figure 1, whereupon when the roller 23 is 'moved downwardly into the guide'way 39, the shaft 11, arms 27, rod 27 and side guide member 28 will be moved to the'lelft for rside registering a sheet of material and compressing the other coiled spring 37. As soon as permitted, this coiled spring will return the shaft l1, arms 27, bar 27 and the side register member 28 to their normal position. lThe control member 38 may be secured in either of its operative positions by a screw or bolt 40.

When the side register member is in an inoperative or raised position, it is lifted above the table 41 on which the sheet material is side registered, and when the member 28 is in its operative position for side registering a sheet, it is lowered, as shown in dotted lines in Figure 5. The enlarged or lower portion 42 of the side register member moves into the groove 43 in the table or support 41 and the laterally extending rod 27 lies just over a sheet of material 45 for holding the latter in position and for preventing same from buckling. It pre vents bucklingvnot only transversely across the sheet as it is being it also prevents buckling of the sheet longitudinally thereof. This rod 27', which eX- tends completely across and over a sheet lof paper being fed, is particularly valuable as an anti-buckling device in cases where relatively thin` and flexible paper is being side registered, in which case there is a natural tendency for the paper to buckle longitudinally in the direction of the feed when the side guide member 28 engages the side of the sheet and pushes the latter sidewise on the table or support 41. However, such buckling is positively prevented by means of the rod 27, which extends across the entire sheet and directly thereabove.

The shaft 11 is given a rotary oscillatory movement for dipping or swinging the side register member 28, by means of a cam member 46 secured to the frame 10 of thev press and a roller 47 mounted in a collar 48 secured to a sleeve 49 which in turn is sesecured to the shaft 11 by a key 50. It is apparent, therefore, that when the roller fed forwardly, but

47 moving downwardly rides over the cam 46', the sleeve v49 and shaft -11 will be given a countercloclwise movement, as viewed in Figure 6, for causing the side register member 28 to dip into side registering position. During such rotative movement of the sleeve 49, acoiled spring 5,1 surrounding the sleeve and anchored at one end to the collar 48 and at its other end to a .bushing 52 surrounding the sleeve 49 in the framemember 13, is wound up, storing energy therein for returning the sleeve 49 and roller 47 in a clockwise rotative movement, vas viewed in Figure 6, to the normal position of such parts, as shown in said ligure. It will be understood that the bushing 52 is anchored in the cylinder framemember 13.

Not only is the shaft 11 given a rotative movem'nt as a result ofthe roller 47 riding downwardly over the cam 46, but also the sleeve 14 and collar 22 are rotated at the same time by virtue of the keyed connection 53 between the shaft 11 and sleeve 14 for bodily moving the rollerI 23 for placing itin the proper plane for cooperation vith the slot 39 in the control member 38. In other words, thecam 46 and roller 47 do two things; they dip the member 28 into a Ygiven horizontal position preparatory to accurately side registering a sheet of'material and ca use the roller 23 to take a position whereby it may be received .in vthe gnideway 39 of control member 38 whereby the side register mmber 28 may be moved sidewise to accurately side, regigster the sheet of paper.

All of the parts of this side register mechanism are simple and cooperate in Va novel manner, and are all arranged accessibly to meet all of the requirements. for successful commercial operation.

A bar 54 is carriedby the table 41Jat the front indV thereof and is given the usual up and down movement. The bar is down in engage-ment with a sheet on the table at the time the sheet is front registered with the cylinder grippers for the purpose of Vholding the front edge of the sheet down in a position to be gripped.
