SHEET-REGISTERING MECHANISM FOR PAPER-FEEDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 764,929, dated July 12, 1904.

Application filed August 28, 1903.

T0 (LZZ whom, it Tluty concern.-

Be it known that we, TALBOT O. DEXTER and HENRY HALLSTREAM, both citizens of the United States, and residents of Pearl River, in the county of Rockland and State of New York, have invented certain new and useful Improvements in Sheet-Registering Mechanism for Paper-Feeding Machines, of which the following is a specification.

Our present invention relates generally to improvements in mechanism for accurately moving 'or adjusting a sheet of paper into register position, and particularly to improvements in mechanism designed to be applied to a sheet-conveyer for registering the successive sheets of paper that are conveyed from an automatic paper-feeding machine to a printing-press, folding-machine, ruling-machine, or other machine designed to operate upon sheets of paper wherein it is necessary that the successive sheets should be properly positioned in transit from the feeding-machine.

Our invention comprises a sheet registering or adjusting instrument which is capable of first moving inwardly over asheet or a conveyer or other suitable support without buckling or displacing the sheet laterally, then moving outwardly upon the sheet without disturbing the sheet until it reaches its register edge, and finally accurately gripping or engaging the sheet at its extreme register edge on its outward stroke and moving the rigidly-held portion of the register edge of the sheet into engagement with the gage and there releasing the sheet. Our registering instrument is given a sufficient length of stroke to insure the engagement and registry of sheets in the extremes of their lateral positions as supplied to the conveyer or other support from the automatic feeding-machine, the point in the return stroke of the engagement or gripping of the sheet by the instrument depending upon the lateral position of the sheet with relation to the gage. The gripping or engaging of the instrument with :theextreme register edge of the sheet insures accuracy of register, for the reason that the part of the sheet which is moved against the gage is held rigidly by the instrument,

Serial No. 171,107. (No model.)

at one side of a sheet-conveying frame and arranged to guide the register edge of a sheet over it into operative relation to the registering instrument, a bifurcated or two-part registering gage or plate mounted upon the sheetsupporting plate, a reciprocatory frame upon which is pivoted a spring-pressed finger,a frictional sheet-engaging roll freely journaled upon said finger and adapted to operate in a shallow transverse groove or depression formed in the upper surface of the sheet-supporting plate, a ratchet-wheel secured to the frictional roll, and acontrolling pawl or dog pivotally mounted upon the finger in operative relation to the ratchet-wheel and formed with a depending tripping-finger which works in a transverse slot in the sheet-supporting plate, so that when a sheet of paper is presented upon the plate over said slot said tripping-finger by its support upon the sheet will hold the pawl or dog out of engagement with the ratchetto move freely over the surface of the sheet in either direction until the trippingfinger moves beyond the register edge of the sheet and falls into the slot, when the pawl or dog will engage the ratchet of the friction-roll and hold the roll against further rotation, so as to cause it to frictionally engage the sheet directly at its register edge. With this construction it will be observed that the frictional roll will engage the sheet at its extreme edge, so as to leave practically no margin projecting beyond the roll, thereby avoiding crimping or buckling the edge of the sheet between the roll and gage when the roll moves the sheet into engagement with the registering-gage.

In order that our invention may befully understood, we will first describe the same with reference to the accompanying drawings and afterward point out the novelty thereof in the appended claims.

In said drawings, Figure 1 is a detail plan view of part of the sheet-conveying frame of the automatic feeding-machine, showing the application of our improved registering mechanism thereon.

We have illustrated our invention as ap-v plied to a sheet-conveyer of an automatic pa-' filed. October 25,1902.

1 represents the impression-cylinder, 2 the front gage, 3 the under guides, and 4 the feed-board, of a printing-press.

5 represents part of the frame of an automatic paper-feeding machine.

6 is the feeding-machine tape-roller driven by a part of the feeding-machine in a manner well understood.

10 represents the side bars of the frame which supports the sheet conveying mechanism which carries the successive sheets from the feeding-machineto the printing-press or other machine. These bars 10 are pivotally mounted upon the feeding-machine frame at 11 and carry upon their forward ends the side brackets 12, upon which are mounted the side registering mechanism, hereinafter described,

and the press-controlling devices, which are partly indicated, but not described in detail, since they do not form any part of our present invention. These side brackets 12 rest upon the feed-board 4 and also carry the metal plates or bars 14, which form an incline leading to the gage end of the feed-board.

15 indicates one of a pair of adjustable brackets or carriages which are mounted upon the side bars 10 and are provided with setscrews 16 for clamping them in the desired adjusted position upon the side bars. journaled in these brackets or carriages 15 and extending from side to side of the ma Freely or carriages 23 and 24 are mounted upon the side bars 10 of the conveyer-frame, set-screws 25 being threaded into the carriages 23 toengage the side bars 10 and hold the said carriages in the desired adjusted position. Connecting-bars 26 are pivotally mounted upon the cars 27 of carriages 23 and adjustably held in sockets 28 by set-screws 29 upon the carriages 24. By adjusting the carriages 24 upon connecting-rods 26 the tape-roller 22 can be moved toward or away from the taperoller 21 for loosening or tightening the tapes 20. By means of the adjusting screw 25 both sets of carriages 23 24 can be adjusted in the plane of feed by sliding upon the side bars 10. This adjustment is for the purpose of bringing the delivery tape-roller 21. nearer to or farther from the registering-gages of the press or-other machine to which the conveying mechanism is applied.

The tapes 20 are driven by means of a band or tape 30, passing around the roller 22 and roller 6, the intermediate pulleys 31 32, and belt-tightening pulley 33, carrying the weight 34. The upper carrying portion of tapes 20 is in the same plane as the carrying portion of tapes 18, and the tape-roller 22 is arranged between tape-rollers 6 and 17, so that tapes 20 are interlapped with tapes l8 and can be adjusted in the plane of feed without interfering with the feeding relation between the tapes.

Parallel sheet-supporting bars 60 are mount ed at their opposite ends upon transverse rods 61 62, which are secured between the side bars 10 of the conveyer-frame. These main sheet-supporting bars 60, which are formed with angular upper faces, rest in a plane lower than the feeding-plane of the sheet-carrying tapes 18 and 20 and extend from a point a little in front of the tape-roller 17 to a point a little beyond the limit of forward adjustment of the delivery-roller 21 of the second set of tapes 20. These sheet-supporting bars 60 are adapted to receive the successive sheets from the carrying-tapes and deliver them to the final feeding and transferring devices hereinafter described.

65 represents barsor fingers having angular upper faces corresponding to the upper faces or bars 60 and angular grooves 66 in the under faces of their forward ends, which fit snugly over and slide upon bars 60. These fingers 65 arepivotally mounted upon therod 67, supported in the adjustable carriages 23 of the second set of tapes. Two complete side registering mechanisms are employed on a conveying-machine, one of which is arranged at or adjacent to each side. The structure of each is the same, and but one will be specifically referred to. The operating means for the two mechanisms are independent, and one is disconnected while the other is operating.

Mounted in the side brackets 12 of the conveyer-frame and extending from side to side thereof is a rigid supporting-bar 75. Adjustably mounted upon this supporting-bar at each side of the machine is a registeringbracket 76, which may be clamped in any desired adjusted position by the clamping-screw 77, passing through the integral lugs 78 of the split collar portion 79 of the bracket. This bracket 76 has formed integrally with it the rearwardly-projecting guide- lugs 80 and 81, in which slides the operating-bar 82 of the registering mechanism. J ournaled in a suitable socket 83 is a pinion 84, mounted on a vertical pin 85, provided with a milled wheel 86. This pinion 83 meshes with a rack 87, cut in the face of the supporting-bar 75. By loosening up the clamp-screw 77 and rotating the pinion 83 the registering-bracket 76 may be adjusted upon the supporting-bar 75 to any desired position transversely of the machine.

is the sheet supporting or registering plate, formed with an integral lateral projection 90, which is rigidly secured to the bracket 76 by suitable means, such as the screws 91. This sheet-supporting plate 90 extends longitudinally of the conveyer-frame and is formed with a slot 92 in its rear end to enable it to fit over one of the sheet supporting and guiding fingers 65, as shown in Fig. 1 of the drawings. The ends of the sheet-supporting plate 90 are deflected downwardly to facilitate the passage of the sheet over the plate, the rear slotted end of the plate being bent downwardly sufficiently to intersect the plane of the sheetsupporting fingers 65 to insure the passage of the successive sheets over the plate.

The plate 90 is formed with a shallow transverse groove or depression 95 for the purpose presently to be explained. Rigidly attached to the lateral extension 90 of the plate is the bifurcated registering-plate 100, formed with the two registering arms or shoulders and the central slot or recess 100", having inclined portion 100". The two shoulders 100 are arranged upon opposite sides of thetransverse groove or depression 95 of the sheet-supporting plate for the purpose which will presently be explained. The plate 90 is cut away or slotted at 90 in line with the shallow depres sion 95 and directly behind the registeringfaces of the arms 100. The purpose of the slot 90 is to receive the auxiliary registering-plate 102, which is secured at 103 to the outer edge of the registering-plate 100 and projects inwardly with its registering-face in the same vertical plane as the registeringfaces of the arms 100. This registeringplate 102 may be adjusted by a screw 104 to bring its registering edge more or less above the surface of the bottom of shallow recess or groove 95 of the sheet-supporting plate.

105 is a cylindrical head formed with a longitudinal bore which fits upon the reciprocatory operating-bar 82. The head 105 is provided with an internal spline 106, which fits in the longitudinal groove 107 of the bar 82, so that the head 105 can slide upon the bar 82, but cannot turn thereon. The head 105 is confined between the lugs 80 and 81 of the bracket 76, said lugs 80 and'81 being a sufficient distance apart to allow for the working stroke of the bar 82.

Formed integrally with and projecting laterally from the head 105 is a centrally-bored cylindrical lug 110, in which is mounted a frictional block 111, shaped to fit snugly against the bar 82, and a spring 112, engaging the block 111 and adjustably confined within the lug by means of a disk 113 and a screw-plug 114:, the latter of which is threaded into the open-threaded end of the lug 110. The purpose of the spring-pressed frictional block 111 is to yieldingly secure the head 105 to the bar 82, so that the head and attached parts, hereinafter referred to, will reciprocate with the bar 82 within the limits of the bracket- lugs 80 and 81. The head 105 is also formed with a horizontal flange 115, formed in its upper face with a square groove or recess 116, in which fits a square key or shoulder 117, formed on the lower face of an angular bracket 118. A screw-post 119 passes through a suitable opening in the angular bracket 118 and is threaded into the flange 115 for detachably securing the bracket to the head 105.

Projecting forwardly from the upright arm of the augular bracket 118 is a pivot-pin 120, upon which is pivoted the inwardly-projecting finger 121. Secured to the upper end of the Vertical arm of the angular bracket 118 is a leaf-spring 125, which projects over into engagement with a pin 126, projecting laterally from the pivoted finger 121. A screw 127, threaded through a rigid plate 128 of the bracket 118, engages the spring for adjusting its tension. The spring 125 tends to force the pivoted finger 121 downwardly for holding the sheet-engaging friction-roller in engagement with the sheet-supporting plate to cause it to operate properly.

is a frictional sheet-engaging roll freely journaled upon the pin 131, projecting laterally from the finger 121. This friction-roll 130 is-formed, preferably, of a suitable rubber which will possess the necessary frictional quality to engage and move a sheet of paper.

Upon one side of the roll 130 is secured the ratchet-wheel 132, by which the rotation of the roll is controlled.

The sheet-engaging roll 130 is supported in line with the shallow groove or recess 95 of the sheet-supporting plate, so that in its travel inwardly and outwardly over the plate it will operate in said groove or recess or upon the portion of a sheet which is supported over said groove or recess. The cut-out portion 100 between the arms 100 of the registering-plate 100 being also in line with the groove 95 of the sheet-supporting plate will allow the friction-roll 130 to move outwardly beyond the registering-faces of the registering-plate and up upon the inclined portion 100 of the registering-plate to raise the roll out of contact with the sheet of paper immediately after the sheet has been registered.

Projecting from the pivoted finger 121 from the side opposite to the friction-roll 130 is a pin 14:0, upon. which is journaled a trippingfinger 14:1, to the upwardly-projecting flange 1 12 of which is rigidly secured a pawl or dog 1 13, which is supported in operative relation to the ratchet-wheel 132 of the sheet-eng aging roll 130.

The sheet-supporting plate 90 is formed with a transverse slot 150, into which the trippingfinger 1 11 projects when said slot is not covered by a sheet in transit through the machine. WVhen the tripping finger projects into theslot 150, the pawl or dog 1 13 will be allowed to engage the ratchet-wheel 132 to thereby hold the friction-roll against rotation.

.The operating-bar 82 is reeiprocated inwardly and outwardly through its supportinglugs by means of a horizontally-movable bellcrank lever 175, journaled upon the side bracket 12 and connected with the yoked head 176 through the link 177. The head 176 is rigidly secured to the outer end of the reciprocating bar 82 by means of a set-screw 178, said head 17 6 sliding upon the supportingshaft to assist in guiding the bar 82 in its movement. The bell-crank lever 175 is conneeted through a rod 180 with the lower end of the lever 181, journaled to the feeding-machine frame at 182 and carrying in its upper end an antifriction-roller 183, which operates upon the periphery of a rotary cam 184E, driven from the feeding-machine. A separate operating mechanism is provided for each registering device, as stated above.

The operation of the device will be clear from the following brief explanation. By loosening the clamping-screw 77 and adjusting the main bracket 76 through the means of the pinion 84 and rack 87 the registering device is placed in proper position to suit the size of sheets to be fed through the machine. The clamping-screw 77 is then again tightened up for holding the mechanism in its adjusted position. When the operation has started, the

change in position of the main bracket will necessitate the adjustment of the sliding head 105 upon its operating bar 82. This is accomplished automatically by reason of the described frictional connection between the head 105 and the bar 82, the engagement of the head 105 with either of the shoulders 80 or 81 causing the head to shift to the required position upon its operating-bar. In the reciprocation inwardly and outwardly of the operating-bar 82 the head 105 carries the sheet-engaging roll, controlling-dog, and tripping-finger inwardly and outwardly over the sheet-supporting plate and sheet which is to be registered. As the mechanism moves inwardly the roll 130 will rotate freely over the supporting-plate and sheet either by reason of the slipping of the ratchet under the pawl or by reason of the disengagementof the pawl from the ratchet by the supporting of the tripping-finger on the sheet. The engagement of the roll with the sheet over the supporting-plate will depress a portion of the sheet into the shallow groove or recess of the plate, thereby enabling the roll to get a better frictional hold upon the sheet when its rotation is arrested upon the return stroke and also serving to stiffen the register edge of the sheet at the point of registry. Upon the outward movement of the mechanism the friction-roll will continue to rotate freely upon the sheet without moving it so long as the tripping-finger is in engagement with and slides upon the sheet; but the instant that the lower edge of the trippingfinger reaches the register edge of the sheet it will descend into the slot 150, and thereby lower the pawl or dog 1 13 into engagement with the ratchet 132, thus preventing the further rotation of the friction-roll. The shape of the tripping-finger and its arrangement with relation to the roll are such that this frictional. hold upon the sheet will take place when the register edge of the sheet is approximately vertically beneath the axis of rotation of the roll. In other words, the roll will frictionally grip a sheet directly at the edge which is to be registered. The device then continues to move outwardly, sliding the sheet transversely across the supporting-plate by reason of the grip of the roll upon the sheet until the register edge of the sheet comes into contact with the registering-arms and the registering-plate 102. The plate 102 projects above the lower surface of the depression 95 about the thickness of the sheet, or just enough to engage the register edge of the sheet directly beneath the periphery of the frictionroll, and by reason of the engagement of the sheet with the register- faces 100 and 102, further assisted by the movement of the frietion-roll up the incline 100 of the registeringplate, the sheet will be freed from the registering-roll and allowed to rest in proper register position. The front guides of the press ICC is out of operation, it is preferable to remove such inactive mechanism from the machine. This is provided for by the screw 119, which detachably secures the bracket 118 of the registering device to the registering-head 105.
