' Be it known that 1, MICHAEL A. Dnorrnew and useful Improvements in Mechanism fo'r Registeri'n Sheets; and I hereby lowing is a full, clear, and exact description =thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in mechanisms for registering sheets of paper and the like in position to be fed to mechanism for operating thereon; such as printing presses; and the invention has particular reference to means for registering the sheets fed to such presses in position to be seized by the grippers of the impression cylinders. v 1 I My invention provides means for both side registering and front registering the sheets; and for supporting the main operative parts of such mechanism and operatively connecting same in such manner thatthey cannot get out of time; such register operating mechanisms being practically movable as a unit and being preferably mounted in a support or frame which can,

be moved or swung up out of the way at any time, if the operator for any reason wishes it. Heretofore the front registering devices and the side registering devices have been usually separately supported and operated so that they are liable to become disarranged or thrown out of time when one or the other or both are moved out of the way; but in my invention the registering V mechanisms are kept in' time both when in o erative position and when out of such posltion, so that in all positions the register actuating mechanismswhether raised. or lowered, or in operative or inoperative positionswill remain in time, and thus save time and annoyance in adjusting the various registers to act in proper time asrequired for feeding of the sheets. I

The invention includes novel means for operating the side registering devices and the front registering devices; also novel means whereby the sheets may be registered either on the right hand or feeder side, or on the left hand or gear side, of the press as may be desired; novel means whereby the sheet registering devices can be readily swung up or'moved out of the way as a unit Specification of Letters Patent.

whenever it is desired to make ready, the" press, or get at the sheet gages, or cylinder,

or to raise the feed table, without destroylng the time relation or drivin means of such regulating mechanisms; a so certain mlnor novel features of construction and novel combinations of parts hereinafter explained. v v

I will explain the invention with reference to the accompanyin drawings which illustrate one practical embodiment thereof;

but I do not consider the invention restricted to the particular construction of parts illustrated in said drawings, as thesev may be varled while retaining the essential novelcharacteristic features and advantages of the invention; and I therefore refer to the claims for'summaries of the essentials of the invention and novel combinations and novel constructions of parts for which protection is desired.

Figs. 10 and 11 are enlarged top and end views of one of the side registering gages.

I will explain the invention as employed in connection with a sheet printing press having a rotatable impression cylinder to which the sheets are supplied over a feed table, and their forward edges are alined against front sheet gages in position to be taken by the grippers on the cylinder by front registering devices substantially in the manner described in my Patent #1,196,934 of Sept. 5,1916. Obviously, however, the invention is usable in connection with other kinds of presses and machines to which it is desired to supply sheets in a uniform accurately positioned manner. 7

Various mechanisms have been heretofore employed for front registerin the sheets against the front gages, and various means have been used to register the sheets against either right or left hand side gages, and effective front and side registering means are shown in my said patent. My present invention therefore has particular reference to the means whereby the sheets may be alined against both front gages and right or left side gages, as may be desired or required by the work being performed on the press, and to render all such mechanisms easily adjustable as a unit into and out of operative position without disturbing their relative adjustment or time.

As conventionally illustrated in Fig. 1, the impression cylinder C is provided with usual grippers c, and the sheets are supplied thereto from a table T, which may be of any desired construction, and the sheets may be fed forward over said table, either automatically or by hand. The front edge of each sheet is arrested by front sheet gages of any suitable kind(preferably like those shown in my aforesaid patent, and indicated at G in the drawings)u ntil the sheet is taken by the grippers 0. These parts may all be of any desired construction, and arranged to operate in the usual manner and,

per 86 form no part of the present invention.

In order to properly position the sheet S on the table T, it is not only desirable that the forward end of the sheet be alined against the gages G by suitable front registering devices, preferably such as are described in my aforesaid patent, but it is also desirable that the sheet be alined against side gages indicated at g, which may be also of any suitable desiredl construction, but preferably such as are hereinafter described, and it is desirable in some cases to aline the sheets against side gages at the right-hand of feeder side of the press, and in other cases desirable to aline the sheets against like gages at the left hand or gear side of the press.

In the embodiment of the invention illustrated in the drawings the main operative arts of the registering devices are mounted in a tiltable frame or support arranged above the cylinder.

As shown, this supporter frame preferably comprises a centrally disposed member 1 and two end members 1", substantially similar to member 1, which members may be cast; and each member 1, 1*, is fastened at one end upon a shaft 1 journaled in brackets 1 of any suitable kind attached to the side frames of the press, as indicated in Flg. 1; the other ends of the members are connected by a tie rod 1 and a pair of parallel rods 1.

A shaft 2 is journaled in members 1, 1" intermediate the shaft 1 and rods 1, and on said shaft is fixed a gear 2 which may be if the invention is applied to a two revolution printing press the shaft 2 will be turned oncecfor each two revolutions of the cylinder On the shaft 2, preferably adjacent the intermediate'member 1, is keyed a disk 3, which has two diametrically opposite notches 3 and 3 in its periphery, either of which may be engaged by a dog 4 pivoted on a cam-member 4 that is loosely mounted on the shaft 2 beside the disk 3. Said cam member has on its face opposite the disk 3 an eccentrically disposed race-cam'portion 4 which is engaged by a roller 4 on a slidable rack bar 4 that has a bifurcated end 4 loosely embracing the shaft 2, and its toothed portion is guided by a bracket 4 attached to the rod 1 adjacent the cam.

The rack 4 meshes with a segment 5 piv oted on a stud 5, attached to member 1; and oscillates this segment as rack i is reciprocated by the cam 49. Pivoted on stud 5 and attached to the segment 5 is a second segment 5 which meshes with a rack 5 on a casting 5 attached to a rod 5 which is slidably mounted in the end castings 1* and lies parallel with and intermediate the rods 1, (see Figs. 4 and 6). This rack 5 and rod 5 will be reciprocated endwise when rack 4 oscillates the segments upon the rotation of cam 4 Upon the rods 1 are mounted the actuating members of devices for side registering the sheets, and to enable the sheets to be registered at either side of the machine I provide two sets of side registering devices, one adjacent each member 1*.

As shown more particularly in Figs. 5, 6 and 8 each of such devices comprises an H-s'haped casting 6 having opposite sleeves slidably mounted upon the bars 1 and connected by a bridge piece 6. Pivotally suspended from and between the sleeves 6 at opposite sides of the bridge piece 6. are double inverted U-shaped members 6 and 6 which are pivoted at their upper ends on pins 6 and 6 to ears on sleeves 6. The legs of members 6 6 depend between the sleeves 6 and below the rods 1 and are pivotally connected at their lower ends to a brush-member 6 which is suspended thereby.

Slidably mounted upon the rods 1 is a Tshaped member 6 which is adj ustably con: nected with the rod 5 by a set screw 6 so that it will be reciprocated by and with the rod 5. This member 6 has a central extension 6 that extends between the sleeves 6 and between the arms of the levers 6 and this extension has pins 6 on its sides which enga e inclined slots 6 in the legs of the mem ers 6", see Fig. 5.

As a result of this construction when the member 6 is moved toward the member 6 the pins 6 engaging the slots 6 cause the members 6", 6 to swing so as to lower the brush-member 6 into engagement with a sheet of paper S lying upon the bar 7 and move the sheet sidewise into engagement with the side register gages. v When the rod 5 moves the casting 6 away from the casting 6 the pins 6 within slot 6 swing the lever 6 and bar 6 upward and disengage same from the sheet.

The extent of lowering of the brush-member 6 or the pressure thereof upon the sheet S. can be regulated by means of a screw 6? which is tapped through an angular extension 6 on the upper endlof the member 6 overlying the bar 6 and screw 6 is provided with a lock nut 6". When the rod 5 is moved so as to cause the lowering'of the brush-member 6', as described, it can be lowered until the screw 6 engages the member 6 and then further movement of the bar will cause the brush-member to travel lineally with the bar 5.

' The lower surface of the brush-member 6 may be provided with any suitably frictional rubbing or sheet engaging surface, preferably a brush 6 as indicated in the drawings. Two sets of such sheet engaging devices are mounted on the rods 1 at opposite sides of the central member 1; and either of these can be adjusted toward or away from the member 1. Either of such sheet engaging'devices can be operated, according to whether the sheet is to be registered at the right or left hand side.

The members may be adjusted to any de-- sired position on the bars 1 and rod 5; and

then member 6 fastened to the rod 5, when adjusted, by means of thumb-screw 6*.

The casting 6 may be provided with a yielding frictional device (such as spring 63 shown in my aforesaid patent) to prevent its moving with the casting 6 until after the brush-member has been either varied or lowered, then it will move with the cast-,

To assist the said devices in side registering the sheets I preferably use a transverse slide bar 7 underlying the sheet and set in a channel in the table T. This bar 7 may also be operated by and from the rod 5, as indicated in Figs. 5 and 7. For this purpose an upstanding bracket 7 a is attached to the bar 7 near one end thereof to which is pivoted a finger 7", which projects above the rod 5 and is adapted 'to engage a notch 5 in the rod 5, the finger being yieldingly pressed toward the rod and into engagement with said notch by spring 7 If, for any reason, the bar 7 shouldbe slightly displaced relatively to the rod 5 when the registering devices areraised, (as hereinafter explained)' w ward, and the latter finger would ride yieldingly' against the rod.5 until the notch 5 therein engages the finger; then the slide 7 would be locked to and move with the rod 5' and properly coact with the brush 6 in side registering the sheet. The sheet is lightly grasped by and between the brush member and bar when the latter are moved in the proper direction and drawn up against the proper side guide and registered thereagainst.

If the sheets are to be registered against the right hand side gages the set of left hand members can be moved out of operative position and disengaged from rod 5by loosening screw 6*. If the sheet is to be registered against the left hand sidegages, the right hand members could be similarly adjusted out of operative position and disengaged from rod 5.

Side register gages g of any suitable kind may be used to properly position the side edge of a sheet brought thereagainst relative to the printing surface on the cylinder, as described in my Patent #1496334. Preferably I employ side registering gages, shown in Figs. 3, 10 and 11. Each side registering gage comprises a slotted plate 9 adjustably attached to the table T by suitable screws 9 and having a pair of side lugs 9 in which is rotatably mounted a screw rod 9 which can be turned by hand.

Threaded on this screw is a stud 9 on a member 9 which projects across the bar 7 and has attached to its upper side parallel arms or strips 9 carrying sheet stops 9 on their outer ends. A side guide adjusting fork 9 attached to the stud 9 provides a double bearing on screw rod 9 for the member 9 thereby causing a more positive positioning of the sheet stop 9?.

Right and left hand side gages are provided but when one is used the other may be removed out of the way. Such gages can be easily attached or detached from the table as required. The member 9 and the parts attached thereto can be longitudinally adjusted by loosening screws 9 as is obvious;

in my aforesaid patent; and accordingly segmental brushes 31 are shown mounted on shaft 2 and adapted to coact with the segmental brushes 20 attached to the cylinder C; see Fig. 1. -The said brushes are preferably constructed and adapted to coact and front register the sheet against the gages G substantially as described in my aforesaid patent. I do not herein claim the front registering devices per 86.

It will be observed that I .haveprovided mechanisms whereby the sheet may be registered both against the front gages and against the desired side gages; and that such mechanisms are so mounted that they can be moved out of the way as a unit when making ready, or for any other desired reason, such as for inspection or adjustment'of the parts, and without any of the parts becomin disarranged or out of time.

hen the parts are in the position shown in full lines in Fig. 1, dog 4 being engaged with the notch 3*; the rod 5 and the connected members 6 will be reciprocated as shaft 2 is revolved; and the gear and parts are so timed and adjusted, that after a sheet S has been-fed forward on the table T to the front gages G and after it is positioned against such gages by the front registering devices; the proper side registering device is moved and draws the sheet either toright or left against the proper side registering gage, as may be desired.

As stated when the sheet ward by the tapes it is first registered against the front gages by means of one of the brushes 2 contacting with one of the brushes 31, which in co-action with the brush 20 moves the sheet up against the front gages G, then the sheet is moved by the brushes 6 and plate 7 against the side gages and thereafter is again front registered by the action of the second brush 31 with the brush 20; so that each sheet is first front registered, then side registered, and then again front registered before it is taken by the cylinder grippers; substantially as described in my aforesaid patent.

Assuming that when dog 4 is in engagement with the notch 3* in disk 3 the right hand side member will be operated to register the sheet against the right hand side gage. If itshould afterward be desired to register the sheets against the left hand side gages; the operator should disengage the right hand side registering brush member from rod 5 and move the same to one side out of the way; then move the left hand brush member into operative position and fasten it to rod 5 then disengage the dog 4 from notch 3*, and turn the cam disk 4 manually a one-half revolution until the dog 4 engages with the notch 3". Then when the machine is again started in operation the devices will register the sheets against the left hand side gage. If it be afterward desired to again register sheets a ainst the right hand side ga e the left hand side registering member shou d be disconnected from 'rod 5 and the right hand side registering member connected therewith; then dog 4 should be disengaged from thenotch 3 and the cam S is brought fordisk 4 turned until the dog 4 engages with The frame carrying the registering devicesl may be supported in proper operative position by any suitable means. As shown bolts 1 are'tapped through lugs 1 on the side members 1 and engage the, top of the caps which fit over the jaws on the'adjacent side frames of the machine. When it is desired to make ready the machine or to pack the cylinder, or to raise the table T, the frame and all the registering mechanisms thereon as a unit can be bodily moved out of the way by swinging the frame back upon the shaft 1* as a hinge; and as in my invention all the effective operating parts of such mechanisms above the sheet are mounted upon the movable frame and depend for their operation upon the same mechanisms; they can be handled as a unit, and may be moved with the frame into or out of operative position without becoming relatively displaced or out of time.
