Is a side elevation: the end* of the impression rod, its mmingfilate and -purts di-- rect-ly associat erew .h. Fig. 12' is a sectional elevation of one set of grippers. Fig. 13 is a horizontal sectional view, v ewed from above, of the rod carrying the gripper the turning of the same.

In the machine shown in the drawings the lsten 1 forms art of a frame or stretcher which is ri id y attached to the standards 8 and 4. T e type bed 5 is adjustably attached to the type bed i 6 which are fitted to oscillate on an ax e 7 and at the back form bearings for a shaft 8 which has axles 9 eccentric thereto. These sales are connected b lmks 10 to axles 11 and 12 on the whee s 18 and 14 which are mounted on a shaft 18 and driven from the driving shaft 16'. through a pinion 17 which engages with the wheel 13. The shaft 8 is so arranged that the impression is normally in its on position andou one end of the shaft there is an impression arm '18 by which the shaft 8 is turned through the imression rod 10 to throw the Impression oil by hand or automatically as hereinafter explained.

Fitted to oscillate on the shaft 8 are the ink roller arms 20 carrying the ink rollers 21 Fig. 1., and connected by a link 22 Fig. 8 to the standard 4 by which arran ement the arms 20 are actuated in the neon manner. The ink plate 23 Fi 1 is fitted to rotate in a bracket 24 whic is pivotally connected to the top of the tyB: bed or to a bracket carried b the type d legs 6, and the back end of t e bracket 24 is connected by a link so to an arm 26 which is carried by the tie bar between the ink roller arms 20. The pawl 27, for intermittently rotating the ink plate 28, is carried by a lever 2 which is pivoted on the-bracket 2s and is actuated as it comes into eontact with the cam surface 29 on the bracket 26. B this arrangement the back end of the ink p ate is lowered as the ink rollers '21 move toward.

the ink duct roller 80 and is raised as the ink rollers move in the opposite direction whereby a minimum variation in the tension of the mk roller sprin is obtained. When the impression is on one of the ink rollers comes into contact with the ink duct s typo these rings respectively there are the gripr carrying rings 33 and 34 which are rigidly connected together by the fixed grippers 35. The movable r i pers 36 are carried by side levers 37 w icli are centered at 38 on the gripper rings 33 and 34, and normally the gr: pers are held closed by suitably arranger s rings 88'. The gri per ring 33 is rovi ed with gear teeth w nch enyiage wit a pinion carried by a shaft 39 an on the same shaft there is a second pinion which is engaged intermittently with a rack 40. This,rack is pivotall connected at 41 to a slotted lever 42 w ieh is fulcrumed at 43 and is actuated by a crank pin 44 on a disk 45 which is fixed u on a shaft 46 and driven by a claw finger 4 on a gear wheel 48 which is loosely mounted on the shaft 46 and is driven from the wheel 13, throu h which arrangement the shaft 46 and t e cams upon it are also driven, while the use of a slotted link 42 for driving the rack 40 gives a quick return motion to the rack. At the end of each forward movement of the rack it is raised out of ear with its pinion and at the end of each ack stroke the rack is lowered into gear with its pinion by which arrangement an intermittent rotation is given to the grippers. To enable this to be effected the rpck is fitted to slide horizontally in a guide 49 which is slotted to slide vertically on a die 50 encircling the shaft 80 and is raised and lowcred from a cam 51 on the shaft 46 through a lever 52, rocking shaft 53 and lever 54. For locking the gripper rings in position after each movement and for making sure that the grippers have been moved to their printing an registering position the ripper ring 38 is provided with looking ugs :55 Figs. 1 and 2 and working to con'unction therewith there is a fork 56 carried )y a bar 56' which is titted to slide in brackets 57 011 the .-.tandards 3 and prevented from turning by arms 56, Figs. 1 and 13, which slide in contact with the face of the standard. The f0l'l '5ti is actuated from the cam 59 on the shaft- 46 through a lever 60 and a buffer s )ring 61 which is introduced to insure that t to fork 56 is positively raised to its locking position. The end of the lever 61- hos between a pair of collars 160, 161, the former of which is fast and the latter loose upon the bar 56; and the spring (it, wlueh surrounds the bar 56', bears at one and against the loose collar 161 and at its other and against a collar 156 fast upon thebar. The spring is strong enouigh to support the weight of the fork 56 an the rod 56', and is somewhat compressed when the fork is lifted to its locking position. This arran cment insures an accurate operation of tie locking fork even should the cam by which the movements are controlled become worn.

The frisket irons 62 for holding the s'lcet on the platen are adjustably attached to a bar 63 which is carried by levers 64 from a rocking shaft 65, and ti idly connected to one end of the bar 63 here is a lever 66, the face of which slides in a guide 67 whereby the position of the frisket irons 62 is controlled as they are moved to and from the platen. For actuating the shaft it is titted with a lever 68 which is coupled by a link 69 to a lever 70 which is actuated by the cam 71 on the shaft 46, see Figs. 2 and 4. The end 72 of the impression rod 19 slides upon a plate 73 which is pivoted on the standard 3, and normally this plate is so held b a wedge on the spring 71 that the end of tie rod 72 is directed over the impression stop 75, but when the impression is thrown otl' the wedge is withdrawn from under the plate 73 and the weight of the rod tips the late and the end of the rod strikes against t e sto 75 and the shaft 8 is thereby turned. en the impression is thrown off it is necessary that the motion of the grippers be arrested also, and this is done by raising the claw 47 out of the notch in the disk 45 whereby the shaft 46 is disconnected from the wheel 48 and the shaft is held at rest and always brought to rest in the same position by a lever 76 Fig. 9 which is pulled into a recess m a disk 77, fixed upon the shaft 46 by means of a spring 78.

For actuating the claw 47 the machine is titted with a bar 7. Fig. 4 which can slide in the standards and is prov ded with a truck 80 which is normally held in its inoperative position by a spring 81 and when so bold acts upon the spring 74 to hold its wedge under the plate 73. Pivoted on the outside face of the standard 4 there is a lever 82 which is provided with a recessed end 84 and is actuated by a cam on a wheel 83 which is driven from the wheel 14. Pivotcd on the bar 79 there is a lever 85 carrying a V-ended strip 86 which is designed to be acted upon by the end 84 of the lever 82 but normally is held clear of the end 84 by suitably urrauged springs. Above the end of the lever 85 there is a lever 87 wlleh is connected by a spring to the band im )ression throw oll' lever 88 to allow of the ever 88 being operated atauy time. and when the end 8-1 is clear of the piece 86 the connecting s )ring forces the piece 36 into the path of the end 81 and the rod 79 is moved cudwise at tl'c next inward motion of the lever 92. 'lhis brings the truckt-lo into the path of a lever Ht carried by the. same axle as the claw 47 and the claw is then raised out of the. notch in the disk 45. The s )ring 74 is also liberated and draws its wet gc from under the plate 73 and the impression rod strikes the stop 75 so that whenever the handle 88 is operated the impression is thrown oil and the grippers brought to rest at the same no I time. After the impreuion has been taken the printedsheet iscarried bythe ippers in the direction of the arrow 89 ig. 8 and these grippers are o mad as the tru k 90 on Q the gripper lever 8 sees the cam 01 and the motion of the sheet is arrested by coming into contact with fixed fingers 99 while the 'ppera complete their motion. The sheet as falls on to a set of tapes 93 which are 10 carried by rollers 94 and extend from the right hand side of the machine through the grip ri 89 at the left hand side of the inac ine a any suitable distance beyond. The tapes 98 may have a slow continuous movement or be moved intermittently for each sheet delivered, or they may be moved any desired distance after any desired numbe! of sheets have been delivered to them. In the arrangement shown the left hand end of the shaft 46 is fitted with a disk 95 ca i a cam-96 which fives motion to a rate t. ver 9?. The rite et timing wheel 98 actuated he: the lever 97, is carried by a lever 90 and fitted with one or more nose 8 pieces 100 so arranged that when a nose piece is broufiinto contact with a fixed stud 101 the. ion pulley 102 at the end of the lever 90 is bro t into contact with the disk 93 and th the pulleys 103 and 80 104 and a drivinfico the tapes 93 are actuated tom t printed sheet from under the grippers the outside of the machine. For 0 the grip rs to receive the sheet at bleeding tion there is a lever 86 105 Fif, C which is ruined on the inside face 0 the. standard 8 and provided with a lug 10$ which acts upon the truck 90 when the grippers, are. in the feeding position. For actuat the lever 105 the shaft 16 is rovidicd vi a cam. 10! and the lever has a oiig axle which profects through a slot in the standardud carries a cam truck.

The tablewhich is described more fully hereafteris fitted to oscillate on axles I 108 and is actuated by a cam 109 Fig 8 on the shaft 16 through a lever 110, and axle 111 which has a bearing in the standard 4, a lever 118 inside the standard and a link 114 which is attached to the side frame 120 l of the table.. The surface of the table consists of anuniber of tapes which are continuously rotated from a pulley on the shaft 16' through the driving cord 114', 115 and 116 and suitable pulleys 117, 118 and 119 see u e construction and arrangement of the mechanism for feeding the sheets to the grippers and for automatically stopping the motion of the ippers and throwing the ini reseion of! are shown more particular'y in Figs. 7. 8, 9 and 10. The feeding tab e which is carried and actuated as hereinbefore described is built up of side frames .120 and 121 which are suitably connected together. At the upper end of the table there is a tape roller 12! and at the lower end of the table there is an axle lL'Zl provided with a separate roller lll for can of the tapes ice. Theo tape rollers art in clined to the sides of the table so that the slim-ts fed at lllt' upper end of tlutapes are carried forward and toward the side In 127. At the lower end of the table there is a set of fixed stop pins 128 and ulso a set of liioi'ablc stop pins 12!) which are fixed to a rod 130. iiiid'are normally held in their highest position b a spring. The pins 129 are also connectc by a wire I32 to some lixcd part of the machine so that as the table rises to its highest position the motion of the pins 129 is arrested. The side lay 127 is ad ustably mounted on a frame 133 which is free to more without turning on a rod 134 carried by lllt side frames 120 and 121. Between the frame 120 and the end of the side 35 lay frame I33 there is ii spring 135 by which the side lay is pressed toward the frame 121 and at thcother eiil of the frame 133 there is a wedge shaped collar 130 which is counccted by a link 137 to a lever on the rod 130 and is fitted to work between inclined faces on the end of the frame 133 and on the side frame 121, by and through which the side lay receives a small moti n toward the side frame 120 as the table coin letcs its upward 96 movement and the sheet is t irrcby positively moved to its side registering position. When the table is in its highest sition a sheet is placed upon the tapes an carried by them up to the fingers 138. As the table islowcrcd these fingers are turned with their carrying axle through'a lever 139 which comes into contact with a fixed stop 140 The tapes then carry the sheet up to the pins 129 and into contact with the side lay 127 by which 106 time the table is partly raised and such sheet is smoothed and held in contact with s by fingers 141 carried by a spindle 142 w iich may he fixed or free to turn in arms carried by the sides and 121. The 110 upward movement of the pins 29 is arrested relatively to the movement of the table when the upper end of the pins is just below or about level with the edge of the tlllt'll gripper 3t; and the side lay is also actuated 116 as the table completes its upward movement. through the turning of the shaft 130 uml moves the sheet to its side registering poi-aition. Siinultniioously with this action the tapes carry the sheet toward the pins 128 12 and between the grippers, which are then closed so that the movable gripper 36 follows the sheet as it is lifted by the rising table into contact with the fixed u-ippci' 35 and the sheet is gripped just aitcr it; has been moved into contact with the fixed pin 128. The automatic throw out mechanism is brought into action through a feelei- 143. This feeler is inside the path of the gri ipers as shown in'hig. 7 when the sheet is ed to the and when the rs hare closcfi t imeeler is allowed If it rests on a sheet of paper then the lever 144 is held clear of the grooved end of a lever a 145 and the motions of the machine are eontinued.'hut if no sheet is fed to the gri pers then the t'eeler falls to the position sworn in Fig. 9 and the lever I44 comes into position to engage tln lever H and the rod to 79 is moved endmse by the lever 82 Fi 5. The fceier 143 is mounted on a li ht a unit Htl which is carried by bearings mm the stretcher 2. At one end of the shaft there is the lever H4 and also another lever 14?. 1s livoted at 148 on the standard 4 there is a three armed lever the end a of which carries a cam truck which passes through the standard 4 and is operated by a cam 150 on the inner face of the wheel 83. Figs. 3 and 9 and when so operated its end 6 actsupon the lever 14? to turn the shaft 146 and raise the feeler 148 to the position shown in Fig. 1'. -lhe third arm n of the three armed lever carries an axle for the lever 14a and if the 28 upper eml of this lcvcr comes into contact with the lever 1-H the lever H5 is turned on its axle as this axle moves arouml the center 148 and the lower arm of the lever 145 then depresses the lever 85, Figs. 4 and 9 whereby 30 the stop mechanism is automatically brought into action as previouslv explained. (onnected to the lever H5 there is a spring 155 by which the lever is normally held in contact with a fixed stop 15! and which also 86 arts to hold the three armed lever in contact Willi its actuating cam.
