- Patented Jwry arose;-

u'sual, is blocked or in any other suitable way made immovable, the type bed 3 which carries the type or printing form remaining movable in the ordinary Way. It will be understood, however, that the particular type'or' style of printing press is immaterial and that my invention, as 'hereinbefore st'ated,- 1nay be built as an integral part of the printing press structure or as'anvattachwent, but for the purposes of an under stmiding of my invention I will proceed to" describe the same as herein illustrated and as these-me is-used in practice, that is as an attachment to :1 Gordon press modified slightly in the" manner stated My attachment is provided witha nain frame't forming a support for the different working'parts of the attachment and secured in any suitable manner to the printing press frame 1. At the upper end of this-frame 4' I mount an endless conveyor comprising a pair of transverse rollers 5 and 6 and 1 suitable endless belt 7. By preference this belt is made continuous from side' to side and as clearly shown in Fig. the same slides upon the upper surface of a support 8 located between said rollers alongthe toprea'eh of the belt. This belt is adapted to receive and to slowly feed as required the pile of paper which is placed thereupon in combed-form and kept in that condition and fedby such belt. For the purpose of properly feeding the paper, the endless belt is moved as required, and in suitable manner,

for'instance; by means of the-ratchet wheel 9 operntivelyconnected with the front roller and cooperating with the pawl 10 which is mounted upon the pawl carrier 11 whose oscillation and proper timing as to" movement will be hereinafter describedl The front edge of the pa-p'er is stop )'ed"l)y means of n cross bar 12 having a seriesof rearwardly-e-Xtend-ing fingers 13 which are formed separately or integral therewith and adapted to liei'in grooves 1 formed "in the belt by'reason ofthe fact that the front roller Gisitself provided with :1 series of elm-umfere'n tial grooves 6 ns'clearlyshown in Fig. 5. It will beunderstood that owing to the tension and pliable nature of the belt. the latter will assume the some surfer-e" characteras the frontroller (i.- lly this means the paper will beproperly received and stopped by the fingers l3 and be prevented from following the belt.

For the purpose of separating the top sheets one at a time from the pile of sheets a transverse roller 14, preferably corrugated and of suitable material, such as rubber, is provided. This roller is arranged to be os cillated in contact with the top sheet of paper first in one direction and then in the other and to be slightly raised during the time that such sheet is being pulled from the pile by the feed rolls hereinafter described. In one of said oscillations this roller 14 causes the paper to buckle and because of this function I will hereinafter refer to the same as the buckling roller. This roller is journaled at its ends in bearings 15 and provided with the central shaft or axis 16. In practice this shaft is connected at one end with a bevel gear 17 adapted to mesh with a corresponding bevel gear 18 (Figs. 2 and 6) mounted on and driven by the vertical shaft 19 carrying at its lower end a similar bevel gear 20. This latter gear is I adapted to mesh with another bevel gear 21 I roller is to cause the to which isoperative'ly connected an oscillating crank arm 22 driven by means of op erating connections hereinafter described. In .order to prbvide for a slightvertical movement of the buckling roller a sliding connmtion is provided between the shaft 19 and either one of its bevel gears in the present instance bevel gear 18.

The buckling roller cooperates in the huekling operation with a normally fixed but adjustable transverse bar 23, extending across the pile of sheets and in proximity to the top sheet thereof. The object of this aper to buckle or move upwardly when the buckling roller is oscil lated in a direction to move'the top sheet rearwardly as to its-front portion. In order to accommodate sheets of different thickness this roller 23 is adapted to be adjusted toward or awa from the buckling roller. To thisend an as a means for supporting such roller, the latter is rotatably mounted on a shaft 24 which is adjustably secured in longitudinal slots 25 formed in blocks 26 at each side of the machine, all as clearly indi bated in Figs.'5 and 6. These blocks are carried by andextend forwardly from 'a cross frame comprising the cross bar; 27, preferably having on its underside a sup plemental bar or piece 28 of suitable material, such as wood, adapted to press direct-ly upon the pile of sheets. Said frame also comprises upright ortions 29 located at the ends thereof an connectedby the cross shaft 30. This shaft extends through and is guided by substantially vertical slots 31 in an upward extension of the attachment frame 4 and the same, together with the entire cross frame, is held downwardly upon the paperwith a yield ing pressure b means of springs 32 arranged. in said slots 31. These springs may be adjustable in tension in any suitable i'nanner as by means of the adjusting screws 33. Tu the present instance the roller 23 is held in adjusted position by the bearing shaft 24 adjustable in the slots 25 and held in adjustedposition by means of the clamping bolts St, the ends of the blocks 26 being properly slitted as clearly shown in Fig. 5 to provide for such clamping.

The cross bar 28 and the roller 23 are adapted to press upon the pile of sheets with a yielding pressure but arranged to be slightly withdrawn therefrom at the time when the top sheet after being buckled is being fed forwardly into'the machine by the feed rolls in the manner hereinafter explaincd. To this end I provide a pair of oscillating levers 35 arranged at opposite sides of the machine as indicated in Figs. 5 and 6 with their rearward ends in contact with the underside of the vertically movable boxes or blocks 36 which slide in the slots 31 with the result that when said levers 35 are oscillated upwardly the cross bar 28 and roller-'23 will be slightly raised against the tension of the springs 32. T0 afford proper movement to said levers, the latter are secured to the cross shaft 37, one of said levers, as shown in Figs. 4, 5 and 6, being connected by means of the link 38 to an oscillating bell crank 89 pivoted on the main frame 4. This bell-crank has a cam roller 39 which is so arranged as to cooperate with a cam 39 secured to the cross shaft 48, thereby giving the roller 14 a positive movement to and from the paper.

In front of the buckling roller is arranged a series of rearwardlyeatending fingers 40 whose rearward ends extend downwardly in contact with the top sheet of paper and whose forward ends are. secured to or form a part of a transverse rod or shaft 41 having an oscillating movement. During the time when the buckling roller is moving in its clockwise direction (Fig. 5) for the purpose of moving the front end of the top sheet of paper rcarwardly and buckling the same, the fingers 40 are slightly raised to remove any interference with said operation but after the front edge of said top sheet of paper so being acted upon has passed to the rear of these fingers, the latter are moved downwardly upon the second sheet of paper which will subsequently become the uppermost one, with the resultthat in the movement of the buckling roller in the opposite direction, the front edge of the top sheet will be directed and deflected by said fingers in an upward direction and free from the pile of paper. These fingers 40 are oscillated in proper time with the other mechaend of a lever 44. i This lever, which is pivoted at 45, is provided at its Eenter with a cam roller 46 adapted to cotiperate with and be actuated by a=cam 47, secured to bne of the, main driving'shafts 48 of the machine. In order-to autom'aticaliy keep a uniform depth of paper underneath the buckling roller, that is a uniform thickness of paper between the lower' surface of such roller and the upper surface of the feed 'belt 7, I provide suitable means which, in the present instance, consists of nechanism controlled by the relative position of. the buckling roller' for actuating the feed belt. As

shown, a vertical link 49 is connected at its upper end'with bell crank 39, Figs. 4 and 15, while its lower end is pivoted to the lever 50, the extreme end of -which is connected by means of a link 51 to the outer end the buckling roller is lowered from its normal position, the link 49 is forced slightly downwardly, by reason. of its connections {gs With the bell crank 39 and link 38, with the result that .the lever 50 is slightly oscillated in a clockwise direction, (Fig. 4) so that, a cam roller 52 is brought into the path of travel of the cam 58 secured to the driving shaft 48. When, in its rotation, this cam contacts the'cam roller 52, the pawl-carrier .11 is moved upward by reason of its connection with the lever 50 through the link 51 and the pawl 10 will be caused to en 5 gage a tooth or teeth as the case may be on the ratchet 9 and move the feed belt for- .wardly in slight degree but sufficient to move the pile. of paper forwardly to provide the uniform depth. of paper underneath the bucklingroller.

Vihen the top-most sheet of paper is fed forwardly by the buckling roller and tie flected upwardlyhy the fingers 40, the same will be directed between the two feed rolls 54 and 55, of which the former is positively driven as hereinafter explained, and of which the latter is an idler, b and 6. From these feed rolls the sheet of paper passes between a second pair of feed rolls 56 56 and 57, the former being a positively driven roll and the latter an idler. This idler is spring-pressed toward the feed rolls 56 by means of a spring 58, whose tension may be regulated by the adjusting screw 5%).

The paper is uided to the first set of feed rolls by fingers 40 and into the second set of feed rolls by means oi'guides 60. Figs. 4 an,d 5. From the latter set of feed. rolls the paper passes downwardly in an inclined 60 direction between the carrying tapes 61, the

paper being presented to a transfer frame and presented thereby to the printing mechanism and subsequently delivered from the machine.

I will now proceed to describe the means whereby the machine is automatically stopped whenever the feed of paper is for any reason interrupted or if the paper should be stopped or clogged in its feeding or improperly fed. Speaking generally, such stop mechanism consists of a control; ling means placed in the path of the sheets of paper between the feed tapes for controlling ,the stop mechanism proper which, in the present instance, operates an electric switch controlling the power of the machine and also operates a brake which here acts uponthe fiy-wheel of the press.

Describing the present embodiment of my stop mechanism as herein shown, (Fig. 7), I secure upon a transverse stationary shaft (32 a double lever 63 which is connected with a bell-crank gear 64 by means of link 63*.

I This bell-crank gear 64 is secured to a trans- 20 of i; the pawl carrier 11 hereinbefore' described. -When in the feeding of the paper verse rock shaft 65 and meshes with the gear portion of a segmental gear 66 which is secured to a rock shaft (57. These gears and pinion are located adjacent among the feed tapes, near the lower end thereof, the gears being. arranged at one side of such tapes. The double lever 63 is provided with a camroller 68 which coiiperates with the cam wheel (39 as hereinafter explained. Upon the rock shaft 67 is loosely mounted a bell crank 70 which has a yielding driving connection with such shaftby means of the spring 71 and the arm 72, the spring being connected by studs 73*with said arm and bell crank respectively. Such construction thus provides for a yielding lost motion. The forward end of the bell-crank 70 is hollow or bifurcated '(Fig. 3) and there provided with a detent 74 of irregular shape and pivoted at its central portion at 75. This detent is bell-crank shaped as to its main portion, but provided at one end with a hook 76, the other end being properly weighted, as by means of the slotted arm 77 to keep the same in a normal position. The limits of movement of this detent are defined by'means of the stop pin 78 received by the slot in said arm. This arm is of such a length as to present the detentto the paper being fed through the machine and to cause it to contact such paper and to be oscillated thereby independently -of the bell-crank 70, in the manner hereinafter described. This detent adapted to coiiperate with a disk 79 loosely mounted upon the rock-shaft 65 and of the peculiar shape illustrated in detail in Fig. .13. This disk is provided upon one side with a hook portion 80 and also with a substantially righhanglcd notch 81, while the other side of such cam is cut away or reduced at 82 for a. purpose hereinafter made apparent. Such disk is kept in a normal position relative to its shaft or axis with a yielding pressure, as by means of a. sprin-g. 83 secured at one end to a pin 84, and at its other end to a pin which is mounted on a fixed bracket 86. Upon the rock shaft 65 is mounted a second disk 87 which I will herein refer to as the positive or ratchet disk. This disk, which is illustrated in detail in Fig. 14, is loosely mounted upon this rock shaft or axis 65 and adapted to cooperate with the spring-pressed pawl 88 pivoted upon a pawl-carrier 89 thatis secured in suitable manner to said rock shaft 65, detail of which pawl and pawl carrier are shown in Figs. 10 and 1'2. This pawl 88 is adapted to engage the notch 90 in the ratchet disk 87when. permitted to do so by the disk 79, as hereinafter explained, and to this end this pawl 88 is of sufiicient width to cooperate with both disks 79 and-87 as indicated in Fig. 12. The tendency of this pawl is to engage said notch 90 but it is prevented from doing so whenever the paper is being fed and also being fed in pro er manner by means of the other disk 79 w ichacts as an interference to the action of said pawl and therefore controls the same,for which reason I will refer to the disk 7'9 as the controlling disk. i f

Referring to the operation of the mechanism as thus far described, and assuming first that the paper is being fed properly to the machine, the parts are so timed that when the gears 4 and 66 are actuated in the manner described a sheet of paper is then being fed along the feed tapes in proximity to the bell crank 70 and its detcnt 74. During the feeding of this sheet the segmental gear 66 is moved in clockwise direction, that is in the direction of the arrow in Fig. 8 and the bell crank 70 is moved in-the same direction. During this movement the free end of the hook 76 will come into contact with the sheet of paper and the detent, being very light in weight, will be rocked by the paper during the continued movement of the bell crank 70 as shown in Fi 8, with the result that such detent will ti: retracted as to its hook end and will move upwardly to a plane above or coincident with the notch 81 of the controlling disk 79. Just as soon as the top edge of the sheet of paper has passed by said plane, the hook end of the detent will drop into said notch 81 and take its position therein as indicated in Fig. 9. Thereupon, during the reverse of the oscillation of the bell crank 70 such detent will move the controlling disk in a clockwise direction against the tension of its spring 83. During the first described movement of the segmental gear 66 the rock shaft (55 being oscillated in an anti-clockwise direction (Fig. 8) the pawl carrier 89 and its pawl 88 are oscillated correspondingly, at which time the pawl will ride upon the peripheries of both disks. In the reverse oscillation of the papts hercinhcfore referred to the pawl carrier and its pawl will move In a clockwise direction and the controlling disk 79 will be moved in unison by the detent in the manner already explained, with the result that the pawl 88 will be disabled or rendered inoperative as shown in Fig. 9in other words such pawl will be prevented from engaging in the notch 90 of the ratchet disk and the latter will therefore not be operated. The parts of the stop tnechanism now being described are the controlling elements and the parts hereinafter described will not bedisturbed in their said position.

Now assuming that for some reason the feeding of the paper has been interrupted and no paper is running or being fed by the feed tapes, the detent 74 will not be moved outwardly on the upward movement of the bell crank 70, as hereinbefore described, inasnnleh as no paper is now running, with the result that the hook end 76 of the detentwill engage the hook S0 of the controlling disk which, in the present instance, is held by spring 83 against adjustable screw 91, and the arm 72 continues to oscillate by virtue of the yielding driv ing connection 71. In the succeeding movements, the controlling disk 79 will not be oscillated by the detent but will be held in no mal position by the spring 83 so that in the return movement of the rock shaft 65 the pawl 88 will not be interfered with by the controlling disk but at the proper time will drop into the notch 90 and in its continued movement will slightly oscillate the ratchet disk 87. As a result, the link 92 which is pivotally connected to such ratchet disk will he moved in the direction of its arrow shown in Fig. 11. This link 92 is pivotally connected at its lower end to a bell crank pawl 93, which acts as a trigger holding a lever 94 and its associated parts in the. position indicated in Fig. 7.v This lever and its associated parts are mounted to oscillate on the shaft 62 as an axis and the same is provided at one end with a depending lug 95 which directly cooperates with the trigger 93. This lever 94 is suitably secured to a rock shaft 96 whose upper end is provided with a lateral extension 97 carrying at its free end a stud 98 and a cam roller 99, said stud and roller'being on axes at right angles to each other, Fig. 15. The cam .roller 99 is located on one side ofthe stud 98, in position to cooperate with the eriphcry of thecam 100, while the stu 98 is located on the under side of extension 97 in position to cooperate withiia projecting portion 101 of said cam, Figs. 7 and 15. Vthen the trigger is operated in the manner explained the resistance againstthe move ment of the bearing frame 102 in a clock-v wise direction (Fig. .7) is removed, and the same will be caused to move in such direction as soon as the cavity 103 in the earn wheel is presented to the cam roller 99.

the bottom edge of same will be gripped the cam 15st for producing the desired move cross strip 155 constitutes one of the grip ping aws for engaging the bottom edge of the paper, the second jaw consisting of a strip 158 pivoted upon said cross strip and 2 having projections 15$) forming the jaws proper adapted to cooperate with similar projections or jaw members 160 on the cross strip. The pivoted cross strip is held pressed with. a yielding pressure against the other strip by means ofsprings it'll with the result that the gripping jaws are closed under normal conditions. The lower members of the jaws are provided with a series of pins 162 acting as registering pins for the paper so that the and held by the transfer device in proper registered position.

For deflecting the paper from the plane of its travel to the printing mechanism in order that it. may be delivered at an angle to the delivery inecl'iai'iisni, I employ substantially the same deflect n fingers as shown in my prior application, but I so arrange and adapt the same that such fingers are given an additional function, to-wit the stripping of the paper from the platen. As shown more particularly in Figs. 1, 3 and l, the series of fingers which. are here three in number comprise two portions, :1 main portion 103 and a longitudinal portion 164-, which is adjustable in the base portion for shortening or lengthening the fingers quired. in practice the base portions 163 .are provided with longitudinal channels to receive the portions 164 which are 111 the form of thin strips, the same being clamped in proper adjusted position by means of the clamping screws 165. The fingers are secured to a hollow cross shaft.- 166 which is loosely mounted on shaft 166 and at Whose ends are secured the hell cranks 1(31' held spriug- )rcssed by means of the springs 168. The tinge-rs, as well' as the shaft 166, are providod with a parallel ruler motion by reason of the provision of the two similar arms H39 and lit) and the connecting link 171 the arms H39 being; pivotally connected at their lower end with the cross shaftltiti and at their upper ends to the fixed point: 172. The upper arm W0 is secured to the cross shaft l7?) which is provided with a crank arm 1.74 connected by means of the linlt'175 l which is pivotally connected to the operatmg lever 176. For the purpose of imparting j the necessary rocking movement to such latter lever, the same is provided with a cam j roller 17? adapted to cotipe ate with the cam j wheel 178. By means of this operating connection deflecting fingers are given the del sired movement toward and away from the j platen, the innermost position of such 3 lingers being illustrated by the dotted lines l in Fig. 4. To obtain the additional or l clamping function I provide a spring l pressed plunger 179 which is adapted to be projected at the proper moment against one of the arms of the bell crank 16?, with the result that the fingers will be moved farther to the left (Fig. 4:) and against the paper, 1' thereby clamping the same against. the platen to strip the paper from the type bed or form. in the present instance these plungcrs 1.7.) are actuated by means oflho bell cranks 180 having pin and slot engagement therewith and provided with cam rollers-1S1 cooperating with the cam wheel 182. The desired adjustment of the clamping action is obtained by means of the adjusting screws 183 as well as the adjustable abutment 184.. The movement of the plungers i s outwardly against the tension of the springs 185 which restore the same to normal position. IAs the transfer frame moves upwardly and is in proximity to said defiectii lingers, the latter move outwardly, to the position shown in full lines in Fig. 4 and such frame continues the position to receive and grip the bottom edge of the sheet. of paper. In this upward movement of the transfer frame, the jaws thereof are opened by contact with the cam plates i813 and with. the rollers 18? mounted upon the movable members of the jaws. After the transfer frame has moved below the range of the dedotted line position indicated in Fig. 4 and the plungers 179 thereupon rock such fingers inwardly as to their lower ends and thereby clamp the paper against the platen to strip I it at the proper time. After the paper has thus been stripped from the form, the de fleeting fingers are released from their clamping or stripping position and upon the continued upward movement of the transfer frame such fingers are moved outwardly to a position of non-interference, as already explained. In the forward movement of the transfer frame the top edge of the paper is deflected laterally to the left (Fig. 4-) to the delivery mechanism by means of the inclincd projecting portions 188. The deliv cry mechanism comprises in the present instance endless belts or tapes 18%) and 190 and suitable pairs of rollers 19.1 and 192.

The transfer frame is operated in the present instance from the cross shaft through a series of operating conncrtimis fleeting fingers the latter is moved to the now to be described. To said shaft 48 is secured. a crank arm 193 to which a link 194 is pivotally and adjustably connected. The upper end of the link is slotted and provided therein with a sliding bearing box 195 held in its upper position by means of the spring 196. The upward limit of movement of the box is adjustable by means of the adjusting screw 197. This bearing box is pivotally connected to a vertically movable rack guide 198 sliding on a guide bar 199 and meshing with a pinion 200 which in turn meshes with and drives a pinion 201 secured to a trans verse shaft 202. To this shaft near its ends are secured two pinions 203 which are adapted to engage the rack bar portions 204 of the transfer frame. The degree of movement of the transfer frame is adjustable to a n'icety by means of the stops 205 which are adjustable up and down upon the rack bars 204. The sliding bearing box 195 in connection with the spring 196 forms a yielding driving connection for following up or compensating for the movementof the operating connections after the stops 205 have come in contact with and have been arrested by a fixed part of the machine frame, in the present instance the bearings 157 of the rack bars.

lVhen my invention is made as an attachment to the usual Gordon press I provide suitable means for securing the same thereto and for adjusting it in proper position and in Fig. i I have shown a simple and efficientmeans to this end.--- As shown I provide a metallic frame 206which is secured to the usual feed board support 1 of the press by means of the screw bolts 207. For the purpose of adjusting or leveling the parts 206 and 1. I provide adjusting screws 208. The attachment is connected to and supported by the frame 206 by a parallel ruler motion which not only permits the attachment to ,be

moved outwardly from its operative position but also is adapted to maintain the attachment in working position to which it is adjustable. As shown, parallel links 209 are pivotally connected at their lower ends to the frame 206 and at their upper ends to the main frame 4 of the'attachment. When the attachment is in proper working position it is secured to the 7 thereof;

rame 206 by means of the screw bolt 210 having the hand wheel 211. The attachment is properly leveled or adjusted by means of the adjusting screws 212. l
