then moved into place beneath thesheet as will hereinafter be explained, and simultaneously with this positioning of the feet beneath the sheet, a clapper mechanism interposed in the suction hose releases the vacuum action and permits the sheet to drop on to the separating feet. H

The clapper mechanism shown in Fig.3,

consists of a flat plate or clapper 16 positioned at the end of an arm which is raised and lowered by means of the cam 17 mounted upon the shaft 12 and operating against the roller 18 on the clapperarm. The cam is so set upon the shaft-that the clapper func-' tions at the time when the suction head has 2. sheet in a raised position, and the, separat- 1 ing feet are in place beneath the sheet. The

clapper 'merely opens aivalve in the hose line and releases the vacuum action or suction upon the suction head permitting the sheet to drop on to the separating feet.

Explaining now the functioning of the V separating feet, the feet proper are two in number, shown in Figs. '2, 3, 4 and 5. The feet are pivoted at 19 to the hangers 20 wvhich give them their forward and backward movement. In addition to this moveber 23 havinga bifurcated lower extremity shown at 23. To this member 23 is pivoted a-roller 24 which contacts with a cam 25" mounted upon the rotating shaft 12. This mechanism is bestshown in Fig. 2. vl/Vith the rotation of the shaft, the cam recipro-.

V cates the member 23, and oscillates'the shaft 21 to move the. feet backward or forward against the tension of thesprings 26 attached to the rear extremities of the separating feet,

and also to the hangers 20. In orderto give the feet the raising and lowering movement, there are the crank arms 27 and 27 and supporting right arms 28 pivoted to the arms 27 at 29, and the supporting arms 28 to the separating feet by slidable'pivot pins 30 functioning in the slots 31. best shown in Figs. 4 and 5. The crank arms 27* are fixedly mounted on the oscillating shaft 32, while fixed to the same shaft is the arm 27. 'At the free end of the arm 27 is a cam roller 33 contacted by'the cam 34 also fixed to the rotating shaft 12. As

thecam 34 rotates with the shaft, it rocks the crank arm 27, thereby raising and lowering the separating feet while the previous mechanism explained in connection with the hangers 20. give the feet their forward and backward 'movementifl Thus the feet are actuated to be lowered beneath the paper The details of this mechanism are sheet as it is raised by the suction head and hold the remaining stock} in position while the single'separated sheet is moved forward by the rubber'pushers 35. v The rubber pushers as shown in detail in Fig. 6, consists of rollers 35 bearing in the supports 36 which are positioned atthe end of arms 37 pivoted at 38 to the horizontal stub shafts 39. A coilspring 40 on the shafts 39 give the arms 37 a constant downward tension against the paper stock, the travel of the arms being limited by the stops 41. These stops eliminate undue friction between the roller and paper. Knives 42 are positioned against the rubber pushers 35 so that they are rotatable only in a reverse direction, that is, they rotate when they. are being oscillated in an opposed direction to the travel of the paper sheets.

The stub shafts39 are carried by the arms 43 fixed to the shaft 44 oscillated by arms 45and46 connected by the member 47 to the outside driving mechanism shown in Fig. 3.

The pushers are thus oscillated backward to engage the front'edge of the paper sheet, and asthe pivoted shaft again moves the pushers 35 forward, they are prevented from rotation by the knives 42, and frictionally engage the surface of the sheet, drawing the sheet with them. The sheet is taken up by drop rollers 48 hearing in the'arms 49 which are pivoted on the oscillating shaft 50,

shown in Fig. 3. It is unnecessary to explain the details of the operation of the drop rollers, as they merely assist in feeding the sheets on to the traveling tapes 51 where they are carried along to the impression rolls. I

Immediately in front of the paper stock lating finger 52 shown in Figs. 7 and '9. This load regulating finger is pivoted at 53. and is held in position against the front of the oncoming paper sheet by a weight 54 ing the cam mounted on the shaft 87 The cam roller is held in contact with the cam by means of a spring 61;

When the stock is'in a position so as to hold the load regulating finger in a position shown in full lines in Fig. 7. the stop 56 will contact the notch 52*" and prevent the crank arm from oscillating when the low side of the cam 60 has rotated to contact with the cam roller 59. If however, the front end of the stock recedes so as to permit the weight 54 to move the finger on its pivot so as to assumea position shown in dotted lines in Fig. 7, it will then be in a position where the notch 52'"? Will not support the stop, and

as it is advanced to the'feed is a load reguthereto.

reiagees consequently with. the-.1-.-@tanm-oa the can't the crank arm with assume apositi'onfishown in the dotted lines. Figs? due-.to the. ac-

This rocker arm is loosely moipnted upon theifeed roller shaft 66;wliiel'1-also car lies a ratchet- (57' which i's'fi ned l y attached AI dog 68 is, pivots to ti l-crochet arm, A constant downward rotative tension is kept-upon the arm means of ai spring 69? The rocker arm is connected 'by means" of a connecting rod to ap'i'n 7 1 offset-from the; centerof'tlle gear wheel 72 so that 't-l'ie gear wheel in its rotation will rock the rocker: armu-pon its pivot due to the recipe rocating movement of'the connecting"; rod-70.

Normally the reciprocatory monementof the connecting rod;'du'e to the rotation; of

the gear, is taken up by the'slot the conne cti ng' rodi Thus, it is' obvious that as long as the front edge; of the stock holds the load regulating finger in position;- sliown= infull lines in the crank arm 57' is; prevented from actuating, but as; soon asthe stocl'rdoes not advance tothi'sposifiionsufiicientlyto port the' st'op positioned at the. end; of' -the crank' 57,! the cr a -nlg willbe 'actuatedl due to the: spring tension and will fim otioir the iii-m 6 so that the loclg 64L release-the rocker-arm: The rocker arm will be rocked by the spring 69, and the dog 68 will engage the ratchet and the ratchet will in turn be drawn by the reciprocation of the connecting rod 70 whereby the feed shaft 66 will be rotated and the load advanced.

After passing the load regulating finger, the sheets are engaged by the pushers as explained, and are contacted by the drop rollers 48 which are raised and lowered by cams 7 4 contacting with the rollers rotatably positioned on the arms 7 6. which are in turn fixed to the oscillating shaft 50.

Tension is kept upon the arms 49 which carry the rollers by springs'77. These rolls advance the sheets on to the tapes 51 as explained. The drive to the gear 72 is shown in Fig. 2, power being transmitted from the press through the chain 78 to the sprocket 7 9 mounted on the shaft 80, thence through a gear 81 carried upon the same shaft. This gear meshes with the gear 82 mounted on the shaft 88 which is in turn meshed with the gears 84 and the latter meshed with the gear 85 mounted upon the feed roll shaft 86 over which the feeding tapes 51 pass; The gear far 851is mesheclzwith the lla-rgerggeair 'fi.
