SHEET-REGISTERING MECHANISM. I

Application filed May 1, 1913.

To all whom it fiiay concern:

Be it known that LVFRANK L. Cnoss, a citizen of the United States, residing at Port-Washington, in the county of Queens and State of'Ne'w York, have invented cer-' tain new and useful Improvements in'Sheet- Registering Mechanisms; and I do hereby declare the following to be a full, clear, and exact description of the'invention, suchas will enable others skilled in the art to which j it 'apperta'ins to make and use the same.

This invention relates to paper feeding machines and more particularly to the sheet registering mechanism-of such machines.

The ,object of the invention is to provide novel and improved mechanism for securing the accurate registering of the sheets in feeding the machines in which two sheets are fed side by-side to the front gages of a printing press or othermachine for acting on the sheets;' to provide novel and improved devices for sheets against the front gages which may be used in either two sheet or singlesheet feeding mechanisms;

tions of parts hereinafter illustrated therein.

" crating cams;

to provide novel a'nd improved means for securing the accurate register of one edge of automatically fed sheets against two spaced gagesg and to otherwise improve the construction and mode of'opera ion of the sheet registering mechanism of paper feeding machines.

To these ends the-invention consists in the features of construction and combinadescribed and re ferred to in the claims. I

The various features-of the invention will be readilyunderstood from an inspection of the accompanying drawings and the.follo w- 1 'ing detailed description of the mechanism I In the drawings: Figure 1 is a side elevation of so much of asheetfeeding' mechanism as is necessary to illustrate the application-of the present improvements thereto; Figs. 2 and 2 are a plan view of the registering devicesillustrated in Fig. 1; Fig. 3 is a detail elevation showing'one of the op Fig. 4 is a side elevation devices which are arranged d1.--

,ual sheets from two piles or banks arranged not shown, but may consist of combing'wheelsand sh'eet controlled cutouts such as are fuily illustrated in the patent to Cross, No. 8,152,260, February 13, 1906. The sheets are advanced by the combing wheels into, position between the delivery rolls 1' and the drop rolls 2-and are advanced over the. supporting bars 8 and supporting tongues 4 by the; delivery rolls 1 and their cooperating drop'rolls 2, and by the forwarding rolls 5 and the cooperating;

drop rolls 6. The drop rolls 2 are raised and lowered'in the usual manner by a cam (not shown) secured to the constantly run- '-ning cam shaft 7, and the drop rolls 6 are raised and lowered by a cam on the shaft engaging one end of a lever, the other end of arm on the drop roll shaftll, the. construcwhich engages-a rod 10 connected with an tion'being similar to that shown in'Fig. 3.

The delivery rolls'l are driven by the usual mechanism similar to that shown in the above patent and V driven in unison with the delivery rolls through a chain '12 which passes over a vance the sheets vto auxiliary front gages which are arranged somewhat back of the prevent theengagement of the front edges of the sheets with the front gages. "After the sheets have been thus forwarded and arrestthe. forwarding rolls 5 are wheel on the forwarding roll shaft 18, Fig.2. i

The delivery and forwarding rolls'qadprinting press and I 60' the invention is ill used they are acted upon by side registering devices'which bring the side edges of the sheets into registeragainst two side gages,

after which thesheets are advanced into base plate 16 and so arranged that the

jaws

17 and 18 of the reciprocating gripper may ;.pass between the adjacent ends of the blocks (Figs 7 to 10). The base 16' is slotted to receive the two lower jaws 7 of the gripper and is provided with a guideway for the I gripper carrying slide19. The upper. jaws lower end of the latch lever is arranged to 30 engage one or the other of two lugs 27 and '18'of the grlpper comprisetwo thin fingers pivoted to anarm 20 which is mountedupon a pivot stud 21projecting-from a standard 22 onthe gripper slide. The arm 20 is forced in a direction to close the gripper jaws 18 against the sheet by a spring 23.

The opening and closingof the gripper is controlled by a latch lever '24 pivoted to the standard 22- and provided with a roll v arranged te engage-a recess 26in the rearwa'rdly projecting end of the arm'20. The

' 2-8 which are secured upon the base plate 16.

Whenthe gripper carrying slide is advanced the jaws 18 are held in raisedposition,as indicated in Fig. 8. As the gripper completes its forward movement the lower end of the lever 24 strikes the lug 28 and disengages the roll 25 from the recess 26 so that the v jaws 18 of the gripper are forced against the sheet and form two transverse creases in its edge, as indicated in Fig. 10. The gripper slide is then retracted and the-gripper .jaws act to draw the edge of' the sheet against the fixedgage blocks 15. When the edge of the sheet strikes the gage the lateral movement of'thesheet is arrested and the gripper jaW'stslide laterally along the sheet until the lower end of the latch lever 24 strikes the lug 27 Continued movement of the gripper slide then forces the latch lever toward the left and the roll 25 rides up the inclined end of the arm 20, raising the arm and lifting the gripper jaws 18 into the position indicated in Fig. 8. If the edge of the sheet strikes one gage 15 before it does the other, the gripper engaging that part of the edge which has not been brought against the corresponding gage 15 continues to draw the edge of the sheet toward the gage until. the the gage. At the same time theother gripper is slidedge at this point is arrested by ing over the sheet and continuing to draw the edge at this point against the other age 15', thus insuring the accurate register 0 the edge against the two spaced gages.

The base plate 16 is provided with a hub which surrounds a transversely arranged supporting rod 29. and the base plate may be readily adjusted on-ethe rod by a pinion 30 .,mounted on the base plate and engaging raclrteeth formed on the rod. The p'inion is formed on a sleeve 31 moun'ted in a split boss 32 and provided with a knurled head 33. The base plate may be. secured in adjusted position by a clamping bolt 34 which passes through the sleeve 31 and is provided with a head engaging the lower section of to the end of the-clamping bolt and serves to-force the head of the bolt against the lower sideof the split boss, and a flange 36 on the sleeve 31 against the upper side of the split boss, as indicated in Fig. 7.

The base plate is held from rotation on the rod 29 by a guiding lug 37 which surrounds a rod 38. The rod 383s mounted to move longitudinally in the supporting brackets 39 and.40 and carries a collar 41 provided with a laterally projecting arm 42 arranged to fit between lugs 43 on the gripper carryin slide'19. The collar 41 is split,

.as indicate in Fig. 7, and may beclamped in adjusted position on the rod 38 by a clamping bolt 44. When the side register devices are to' be adjusted transversely of the machine the clamping bolt 44 is loosened so that the collar 41 may slide on the rod 38.

'Ifthe registering devices are to be thrown out of action the bolt 44 may be loosened and the collar 41 swung about the rod.38 to disengage the arm 42 from the lugs 43.

The rods 38 by which the side registering grippers are reciprocated are so connected that the side registering grippers at the opposite sides of the machine move inward and outward in unison. As shown, the inner ends, of the rods 38 are provided with 001- lars 38 which have sliding engagement with the rods 29 and are connected by links 45 with the opposite ends of levers 46, the collars 38 at one side of the machine are con- 'the boss 32. A knurled nut 35 is screwed on I nected'to bell crank levers 47 and 48by links .45. The bell crank lever 47 is connected by .a link'49 with one arm of a lever 50, the other arm of which carries a roll engaging a'cam 51 secured to the cam shaft 7. The link 49 is also connected through a link 52 with the lever 48 so that the levers 47 and -48 are moved in unison.

Each of the auxiliary front gages for positioning the front edge of the sheets preparatory to theoperation of the side registering devices comprises gage fingers 53 formed on the end of a lever 5-1 and arranged to straddle a' thin metal tongue which one end of The lever 54 and rolls'60- are alternately of the sheets. The lever is forced in a direction. to hold the gage fingers 53- in the path of the sheet by a spring 58 and the position of the fingers i sdetermined by a stop screw 59 against which the rear end ,of, the lever is held by the spring. The gage fingers 53 are arranged a short distance back of the front gages 14 and are held in, the path of the sheets asthey are advanced by the forwarding rolls so that the advance-of the sheet is arrested" before its front edge reaches the front gages 1f After'orduningjthe time that the side registering devices 1 are drawing the edges of the sheets against the side gages the levers 54 areraised to withdraw the gage fingers 53 from the path of the sheet, and after the side register of the sheet has been completed the sheet ismoved forward against the front gages by devices which grip the front edge of the sheet and draw the sheet forward so that accurate side and front register of the sheet is insured.

The devices'for gripping and drawing the sheet forward against. the front gages 14 comprise rolls 60 adapted to press the sheets against the tongues When the auxiliary front gages 53 are raised, and means for. ad-

vancing: the tongues 55 While the sheets are engaged by the .rolls so that the sheets gripped between the rolls andtongues are carried forward with the tongues until the" front edges of the sheets strikethe front gages, after which the tongues may slide along the under surface of thesheets. In the construction shown, each roll i's'carried' upon an arm 61 pivotally mounted upon a stud 62 projecting from the lever 54.

The arm 61 is forced in a directionto en- 4 gage the roll with Ithetongue 55 by a torsional spring 63, the tension of which may be adjusted by adjusting the collar 64 to the spring is 'attached.

raised and lowered through a rock shaft 65 to which a lever 66 is secured, One end of the lever isconnected by a link 67 with the T lever 54 and theotherarm of the'lever 66 is connected by a link 68 with the roll carrying arm 61. The upper end of. the link 68 is a connected with the. lever 66 by a pin and slot connection so that the roll 60 may .be free to move with relation to the arm 66 and its pressure upon the sheet will, therefore, de pend upon the spring 63. The rockshaft 65 is operated at-properinterv'als' fromla cam 69 secured to the cam shaft 7 and engag ing one end of a lever 70, the other end of whichis connected by a link 71 to an arm 72 on the rock shaft.

The tongue 55 is mounted to slide in a support 73 secured to atransverse rod 74 and is reciprocated from a rock shaft ,75

through an arm 76 secured to the shaft and.

'- tering devices, andthese sheets which usually have comparatively long side edges and comparatively sh'ort front edges may be quicklyand accurately registered against thefiside gages before their front edges are brought against the front gages and then drawn forward -into accurate register against the front gages without disturbing the side register.

The same machine ,may also be used to feed single sheets "to the front gages. In such "case all but one of the side'registering devices will bedisconnected or thrown out ofa'ction, two of thecomber rolls and cut-- outs will be thrown out of action, the auxili'ary front gages will be rendered inactive, and the timingof the side registering devices With relationto thedevices for ad "ancing the sheets against therfront gages will-be changed by changingor adjusting the cams for-operating the side registering devices and for'depress'ing the rolls 60 andadvancing the tongues 55. In this case the rolls 60 will be depressed and the tongues 55 advanced to draw the front edge of the sheet into accurate register against the two spaced front gages 141 before the side registering device acts to draw the sheet lat erally against the side gage. In this case either roll and tongue will'continue to draw the edgeof the sheet against the corresponding gage after the edge at that point has been arrested, and while the other roll and tongue are drawing the edge against the other front gage, in case 'theedge is out'of alinement when advanced into position between the rolls and tongues. v
