18 Claims. (01. 271-59) My invention relates generally to paper feeding machines, and more' particularly to certain improvements in sheetregistering devices especially side-register guides for gaging the position of the successive sheets accurately in such machines.

The objects of my invention are, among other things, to provide an improved sideregister guide movable bar until the sheet strikes the fixed side gage where it is held flat and supported at the point of contact with this gage while the movable bar slides under such sheet.

My improved sheet-register embodies other features of novelty and improvement whereby the device is rendered simpler and otherwise better adapted and more convenient for use, all of which will be hereinafter described and claimed.

In the accompanying drawings illustrating a preferred embodiment of my invention, Fig. 1 is an end elevation of the imp roved sheet register looking down the feeder 'and's'howing the cam connection in operative position; f

- Fig. 2 is a side elevation looking fromthe right of Fig. 1 and showing the cam operating mechanism and the position of the side guide to the paper feed line; 7

Fig. 3 is an enlarged viewon the line 3-3 of Fig. 1;

Fig. 4 is an enlarged detail section on the line 40' 4 4 of Fig. 1 showing the adjustments for different widths of sheets;

Fig. 5 is an enlarged section on the line 5-5 of Fig.3; and Fig. 6 is a View similar to Fig. 1

showing the parts as the sliding bar is moving 45 to the right beneath the sheet registered against the side gage. i

Similar numerals refer to similar parts throughout the several figures. V 4 Referring to the figures, the side-frame 6 of the feeder supports the register sideguide as a whole along with the bar '7 extending across the width of themachine and. carrying the side register'mechanis'm. The shaft 8 (driven from any suitable source of power) is timed to revolve one 55 for one with the setting of the successive sheets.-

Keyed to the shaft 8 is the side-guide cam 9 that actuates the mechanism for reciprocating the side guide back and forth across the path of the sheets to bring same into proper side registry.

Such mechanism comprisesthe cam-rollers and 11 pinned to the arm 12 whichis pivoted:

on the bracket 12 fast to the side-frame 6, the arm '12 being interchangeably connected to the arm 13 by the pawl 14 pinned to the arm 13 with the pawl 14 engaging the ends of the notch 15 cut in the upper end of the arm 12 (Figfil) The arm 13 is connected to the sliding bar 16 carried. in the bar '7 by the bracket 17 and pin 18 carried at the end of the arm 13. The spring 19 con-j nected to the arm 13 pulls this mechanismin' one direction to cause the roller 11 to follow the, cam 9 with the sheet registered against the fixed, side-gage 20 as shownin Fig. 1.

When the pawl 14; is shifted to theleft end; of the notch 15 (Fig. 1), the rol1er10 is brought into contact with the cam 9 (the roller 11 being then disengaged), and the spring 19 is shifted toconnect with the pin 21 so'thatthe sheets may be registered against the opposite left hand gage (not shown) in the same manner as against the gage 20. V Y i The cam-shaft 22 (Figs. '1 and 2) is rotated once for each operation of the side guide devices and carries the cam 23 which engages the. cam-roller 24 pinned to the arm 25 pivoted tothe. bracket 26 secured to the bar 7. The upper end of the arm 25 is connected by thelink 27 to the rock arm 28 carried by the rock-shaft 29on which is adjustably secured the lever 30 whichengages; the lever 31 Which actuates the upper plate 32 of the register mechanism arranged abovethe path of the sheets. The lever 31 is provided with-the pin-33 (Figs. 1 and 2) I that may be engaged by the hook 34 to lock the lever 31 in inoperative position when desired. The register mechanism? is operated by the arm 25 in one direction while the spring 35 causes the cam-roller 24"t'o follow the cam 23 to operate the arm 25 in the opposite direction. The spring 35 is fastened to the lever 36 keyed to the rock-shaft 29 as shownin Fig. 2 Referring to Fig. 2, when the shaft 29 is'rocked in a counter clockwise direction by the cam 23, the lever 31 fulcrumed on the pin 3 7 (Fig. '1) through the link 38 actuates the sliding member 39 carried in the bracket 40 movably aflixed to the bar '7. This sliding member 39 carries apair of pull wheels 40 having rounded peripheral edges and are journalled in the movable block 41 (Fig. 5) whichis adapted to be raised 'andlcwered in-the pocket 42 and is heldin positionby the plate 43 tension of the spring 47 is. regulated by the screws 50 (Figs. 1 and 2) The coil spring 46 tends to keep the block 41 seated in contact with the top sure. face of the extension 44 (Fig. 5)., but does not tend to make the plate 32 contact with the sheet of paper. The heavier coil spring 47 serves to force this plate 32 into contact with the sheet when the spring 46 is compressed thereby unseat ing or separating the block 41 from the extension 44. Hence as such block 41 is unseated from its contacting position with the extension 44, the plate 32 comes into contact with the sheet S,

but only with a pressure that is the difference between the respective tensions of the two springs 46-, and 4'7. Since these spring tensions are both adiustablethrough the screws 45 and 50, the pressure of the plate 32 on the sheet can be delicately regulatedor controlled so that such plate 32 may make a very light contact with the sheet, while the wheels40 can be made to contact with the sheet S with the full tension of the coil spring 46.

When the sliding member 39 is raised away fromthe bar 16 by the rock-shaft 29 along with the-block 41, wheels 40 and plate 32 (Fig. 5) the two springs 46 and 47 are compressed but with different tensions. As the rock-shaft 29 is moved in. a. clockwise direction (Fig. 2), the sliding mem: ber 39 is lowered with the pull wheels 40 and plate 32 to contact with the sheet S positioned between the plate 32 and the under sliding bar 16, as shown in Fig. 1. Since the spring 47 is stronger than the spring 46, the pull wheels 40 will engage the sheet and sliding bar 16 and the spring 41 continue the lowering movement of the plate 32 while the block 41moves upwardly inthe pocket 42 so as to bring the plate 32 intocontact with: the sliding bar 16 but with less pressure than the pull wheels 40.

The gage 20 against whichthe sheet Sis registered by the bar 16 is set so that it contacts with the bar 16 to prevent thesheet S from entering between the gage 20 and bar- 1-6 (Fig. 5). side, guide mechanism carried by the bracket 40? may be adjusted transversely of the feeder by the bracket 51 clamped to the bar 7' by the wedge block 52 and cap-screw 53 (Fig. 4). The bracket 40 *v may be moved in either direction relatively to the clamped bracket 51 by the knurled nuts 54 (Fig. 1). The sheets S are advanced to this sheet-register mechanism overthe feed rollers55 in the direction of the arrow shown in Fig. 2 by any suitable means.

The operation of this sheet-register mechanism is, substantially as follows: The sheet S is forwarded .by the rollers 55 until itreachestheposition shown in Fig. 5 between the sliding bar 16 andthe superposed plate 32 and pull wheels 40; then in timed relation with the cam 23, the wheels 40' and plate 32 drop intocontact with the sheet by the action of the .springs46 and 47 The wheels 40 will makecontact first and then the heayier tension of the spring 47 will lower the plate- 32 until it also bears on the sheet S with a. pressurelsubstantially equal to the difference intherespectiye tensions of these springs. 46, and

This

47. Thereafter the sliding bar 16 is moved to the right (Figs. 1 and 5) by the cam 9 acting through the arm 12 and the sheet S will be carried against the side gage 20 and registered. As the sheet strikes this gage 20 the bar 16 will continue its movement to the right and slide under the sheet as shown in Fig. 6. By this mechanism each sheet S is held perfectly flat against the gageZO by the plate 32' and bar 16 thereby preventing any curling or wrinkling of the sheet margins and also avoiding any bruising or tearing of the edges. The rounded edges of the pull wheels 40 do not 'interfere with the front or leading edges of the sheets. as they aresuccessively advanced by the rollers 55.

While it is preferred to use the specific construction and arrangement of parts as shown and describedfit will: be understood that such construction is not essential and may be varied and modified as may he found desirable or best suited to the machine in which my improved sheetregister is to beemployed.
