Application tiled March 9, 19009.' Serial No. 482,214.

To all whom it may concern:

Be it known that l.' ARTHUR J. Honor., a citizen of the United States, residing at lasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Printing-Presses, of which the following is a specification.

This inventionrelates to a press of a gen. eral character and operation shown and de scribed in Patents Nos. 867,634 and 872,108 issued to The Mills Automatic Press Company on Oct. 8th, 1907 and November 26th, 1907; andy it consists in generalvimprovements in the mode of operation of the different parts and in the construction of the same to make a more eflicient press. In the latter mentioned patent, which is the basis of the former, a small printing cylinder is utilized, the paperbeing held on the cylinder by suction after being fed thereto by an appropriate feeding means. At the end of the printing operation the suction is released and the paper passes to a collection box 'over a ldelivery apron. The Cylinder is solid in its peripheral portions and is of such a size that it Willaccommodate around its circumferencel the largest sized sheet to -pbc printed. In order to keep the type in the form box from contacting with the' cylinder except when it is desired to printupon the sheet of paper, a mechanism is employed to lower the box duringall but a small portion of its movement, this portion being on the up stroke of the type When the; type has-v reached a position adjacent the`cylinder which at this time has a sheet of the clean paper around it. In this form of press the cylinder rotates during all the timethat the form box on the bed is moving.

.ln the present invention 1t is that the bed and the form box shall reciprocate in a single plane. rather than move in one directizm in one plane and in the other direction in another plane. After being once adjusted so 'that the type bears against the cylinder with the correct 'pressure the type moves in a simple motion of reciprocation. 'lhisinoti'm is supplied by .the same means as in the above mentioned patentsbut it will be obvious that it maybe supplied in any approved manner. ln the present n1a` (chine the cylinder does not rotate `all the time but remainsat rest during the mot-ion of thle bed in oneldirection, which I may call tie arranged feeding and inking motion of the` form suction the edge ofthe sheet for its' removal. When of the machine.

.cross section taken on line 5 5 of Thus alternate quarters of the periphery of the cylinder are cut away and the operation of the whole mechanism is so arranged that when the bed travels back on its inking .movement and the cylinder is stationary one or the other of these cut away portions is over the. type 4in the form box. In this man# ner it is provided that the type does not come into contact With thevcylinder or with any part thereof except when it is desired to print upon the sheet held upon and supported by the cylinder. Upon the back or in'king movement .of the bed and the type in the form box thereon, the feeding mechanism lof the press is arranged and timed to deliver a sheetof paper to the stationary cylinder. This feeding mechanism may be of any preferred form, the construction illustrated being' the one now in use on the press shown.4 Although it does not enter into the presentinvention in its particular formflt is included in the showing so that be complete. In the .present means are employed to engage the same may clear of the pile the sheetv is l dropped into the feed box lof the machine where it is registered'or alinedl accurately just before beingv placedon the cylinder.' p

In the drawings designates the frame of the Fmachine which is rovided with ways 31 for the support of bed) box 33 therein. In the present form the bed plate is shown as being supported on an ineline but this is not necessary to the etlicient working of the press. In the lower-part ofv the frame-is. ournaled a` main shaft 34 carrying a crank 35 which is connected through a connecting rod 3G toa bracket 37 secured to the under` side of the bed plate. The throw of this crank is such that the travel of the bed plate and the type thereon is just suflicient for the operations to vbe hereinafter described. The main shaft isldriven through the agency of a counter shaft 38 to which itis connected by gears 39.,v The counter shaft is providedvvith' a driving pulley 4.0 and la clutch-41 for connecting it to the shaft, the clutchand also a brake 42 being operated by a foot'lever 43 mounted on' the opposite side of the machineand operatv 'ing through a shaft 44. 4By this mechanism the operation of the press may be controlled. Located on the frame at the upper part thereof-,and in proper .relation to .the bed plate, is a .set of inkmg feeders and rolls 45.

As this arrangement is of ordinary construction and has no bearing on 'the present invention it will suffice to say that thefaee of the type in the form box is .inked upon its passage under rolls 46 at the upper end of the stroke. y i l The feeding mechanisms-The sheets are placed ina pile on a tray 50 and the 'mechani'sm 1s arranged to feed the lowermost sheet( from the pile into chute 92. The for* ward edge ofthe lowermost sheet'is bent down by appropriate action of suction apron F55, a valve 114 controlling the suction supply. Fingers 81 then enter4 the pile above the lower sheet and remove that sheet upon their outward movement, the fingers being hollon7 with suction ports at their ends for engagement with the sheet. The fingers are mounted on a reciprocating frame 72 which moves 1n-a cam groove 70 on the frame,

. Amovement being imparted through connecting 'od73farms 74 and 7 6 pivoted at 75,v

and nnecting rod'77 secured to crank 78 on the main shaft 34. Suction is supplied :to the mechanism by a pump 100, operated plate 32 having form from shaft 34. Valves 114 and 113, controlling the' suction supply to the apron and thf` fingers respectively, are' operated lfrom cam shaft through the medium of cams 122..

The alm'ng mechanism-Upon passing into chute 92 the sheet falls to the lower end thereof and rests .upon pins which are set in the. ilnpression'cylinder and which are at rest in the position shown in Fig..

Chute 92 is formed on one'side by a. solid Figi 13. The member which is upon the left in Fig. 5is provided with the alining -mechanism`136 while the member-137 upon the rightA in that figure is not provided with the alining mechanism but consists mainly of curved vwalls 138 and a lateral wall 139. This lateral Wall 13.9 of member 137 forms the gage against which 'the sheets Vare moved by mechanism 136. The alining mechanism consists of a pivoted arm 140 mounted on bracket 141 vby which member 135 is secured'on rods 134, the lower end of this arm carrying portion 142 of lateral wall 139. A spring 143 tends to hold portion 142 inits. normal position but a cam 144 on cam shaft 120 engages a roller 145 to prevent the inward movement of the lower 'end of the varm except when cut away portion.146of reaches the rollerat .the time when the sheet of paper is standing in the lowerend 'of the chute, and portion 142 of the lateral 1111.139 of member 135 then contacts with the edge of the paper and forces the paper against member137.` By this means the sheet is perfectly registered in both directions and is then ready to be taken onto the cylinder.

The cylinder mechanism .-long each `side of. bed plate 32 a rack 150'is placed, this rack being. so designed that its pitch line comes in the same plane as the faces ot' the type on the, bed plate. Each of these racks meshesl with a sector 151 loosely mountedabout hub 152 of impression cylinder 153. -By the'reciprocation of the bed plate the'sectors are continually oscillated through a half revolution. Cylinder 153 is loosely n'iountedon a shaft 154 which' ex-l tends across the frame.

Ou one of its hubs 152 outside of the sector thereon a disk 155 is, rigidlysecured, :this disk beine provided with'two V-shaped notches 151i arranged 4dialnetrically opposite each other. MountedllO on an extension 157 of the main trame is a detent 158 whose spring pressed plunger 152) is ada ted to enter the notches in the, periphery o disk 155 and to thereby resilienlly and yieldix'lgly stop the diskandthe cylinder at the exact position desired without nndue shock. Thedisk is so set on the cylinder that the cylinder-is stopped in the exact position shown. in Figs. 4 and 6, while the spring is so set behind `the plunger thatit may be forced out of the notch at the beginf end of cylinder 153. I The ends of the cylin der are each provided with two apertures 1(52 which are arranged'diametrically opposite each other and 1n the path which 1s Atraversed bypins 1GO so `that the pins will pressed intothe apertures bv normally be n springs 191. This action normally takes place each time the bed plate'reaches the upper end of its travel with the sectors in the position shown in Fig. G. Upon the downward movement of the bed plate the sectors and the cylinder' are rotated in the direction indicated by the arrow until nearly a halfrevolution is completed. Just before the half revolution is completed the cylinder.

is released from'the sectors and isthen carrie'd on by its own momentum until plunger, 159 enters notch 156 andthus stops the cylremoved from its last position. The disengagement .ofpins 160 from' the cylinder is accomplished .up over these wedges and the pins arethere.- by moved outwardly. This, action takes place at the time. above noted, the cylinder Dassin0-` on b its own momentum toits )osin .Y

. `tion of rest so that when the sector moves V the 4 cylinder is back to its original position the pins will not engagewiththe apertures in the cylinder. The cylinder is thusleft in its final position while the-sector moves back to its Vinitial position'.l- .t i

operation of the machine moved as above described upon each downward movement ofthe bed plate. Means are providedhowever foral- In thel normal lowing the bed plate to reciprocate without: d

. the movement of the cylinder. This means is comprised in a'l small shaft 180 extending across the frame abovethe cylinder, this shaft having arms 181 thereon which are connected to depending fingers 182. These fingers are formedvas is shown in Fig. 9 and their lowerdiagonal ends are so placed that by a. rotation \of shaft 180 they thrown into engag ment with heads 1 71of pins 160 when vthe pins are in the position shown in Fig. 3. Thus by rotating shaft 189 by handle 183 in the proper direction the lingers are thrown into such a position that v the pins ride up on 'them and are thus prepressed lbefore referred to, are located.

by meansi of wedges 170l Vmounted on'extension-l. In the course of their'rotation heads 171 of the pins ride may be* vented from making connection with the apertures: in the cylinder. Thus the sectors may be allowed to move without moving the cylinder. y l

Referring particularly to Fig. 6 it will be seen that'portions of the cylinder surface are cut away, only about two'opposite quarters 190 remaining. Over these portions provision 191 is made for stretching a stiff backing -sheet 192 for the support of the sheets t-o be printed upon. Atl one edge of each of the cylindrical surfaces pins 130, Vi'thin the cylinder two longitudinal shafts 193 are placed and a series of spring fingers 194 on each of the shafts presses against one edge of each of the cylindrical faces of the cylin der between the pins 130. A spring 195 connected to each of the shafts provides means for holding the 4lingers 'tightly against the l cylinder.

As before stated, the cylinder is loosely mounted on shaft 154. n one'end of this shaft an arm 196 is mounted, a rod 197 being secured to the arm. This rod extends.

along the side of the press as is shown in 1g.,3 and is provided on its end with a block `198 which is adapted to engage with the .upper end of bed plate 32 at the upper extremityof its motion, so that the shaft and the attached parts are held in the position shown in Fig. G while the bedis-in its extreme upper position'. A spring 199 holds rod 197 and shaft 154 normally in a position rotated ,in the direction indicated by the arrow in Fig. 6 from the position shown in that figure. Mounted on shaft 154 is a disk 200 carrying pins 201 and 202 on its periphery. .At all times when `the cylinder is stationary and except when the bed is at its upper position, as-shown in Fig. 6, these pins stand under arms 203 which are secured on Shafts 193. Shafts 193 are thereby held in sucha position that fingers 194 are moved outwardly from engagement with the surface of the cylinder and are in a position to receive a. sheet between them and the cylinder or torelease a sheet from that position. The position for the fingers which are taking the sheet is shown in F ig. 12, the sheet ropping down chute 92 onto pins 130 in-l side of fingers 194. It will be seen that the pins 130 pass into slots in the ends of lingers 205, these fingers preventing the sheet from sliding olf the ends of the pins. Fingers 194 are moved outwardly between fingers 205. J ust as the'b'ed plate reaches its upper position, shaft 154 is rotated froin its normal position to -the'position shown in Fig. 6 and fingers 194 are thereby allowed to press against the edge of the sheet resting on thel pins 130 and the sheet is thereby rnily held on the cylinder to be carriedharound with it. On the downward motion of the bed shaft 154 is carried again `to its normal iso . hang from4 a stationary support 207.

position, but in the meantime the cylinder he apertures in the cylinder, the wedges behas started torotate, so that arms 203 areging so located that the pins are disengaged carried away from pins 201 and 202 and arenot engaged by them to again lift fingers.

194. To keep the rear' portion of the sheet up against the cylinder inthe movement thereof, long fingers Q06 are provided which The half revolution of the cylinder carries the sheet, which has been printed by impression upon` the type in the form boX, to a. position opposite that from which it started. When in this position arms 203 ride upover pins 202 and fingers 194 releasethe sheet to Afall onto a set of belts 210 which are continuously driven in the direction indicated by the ar- 'row through the medium of gear and belt f collection boX 214k at the lowerI end of the machine.
