The invention provides a. devicefof this class, which, compared with existing types, is "distin-fguislied by greats'implicity andreliability, which isfiirther independent in'its operationfrom the height of the pile, anclcan be easily attached to any printing press "j c The main feature of the invention is theipr'o'- vision of a feed wheel which by means of a; lever and pawl is moved by the printing machine and, after a certain number of feed motions, reciprocates a gripper which in, its end'positi'on grips a-paper strip or tab and places it by 12, swinging motion on the top sheet of thepile; The pawl ofthe feed wheel can be adjusted so that it will feed, at will; 'one tooth'or several teeth so as to vary. the number of feed motions," i. e., the numher of sheets'which'can be depositedduring'one operation cycle of the gripper. The feed wheel cooperates with acutting device which separates strips of any deSiredlength from a paper reel and supplies them to the gripper by means of rollers arranged so that they convey the paper strip only for a certain period determined by the action ofthe feed wheel. The deviceis provided with a counting mechanism so as topermitthe reading of the totalnumber of deposited sheets at any time.
One form of the invention is illustrated in the accompanying drawings, in which Figure 1 is a rear side view of the feed wheel with lever and pawl; Fig. 2, a longitudinal section on the line A-A, of Fig. 5; Fig. 3, a longitudinal section on the line B--B, of, Fig. 5; Fig. 4, a longitudinal section on the line BIB, of Fig. 5, but showing the device in operating condition; and Fig. 5, a
' top view of the device.
When the rod d is displacedrelative to lever t, the distancebetween the axis of rotation ti of the lever t and pin d1 will'be varied and thus also the size of the swinging motion of the holder 01 and thereforethe number of. teeth of the feed wheel a' which are fed by the pawl 0. amount of displacement between the rod (1- and the lever t and thus the number of fed teeth of the wheel a can be alteredby the set nut e whose screw-bolt e1 is securedfto the rod d. The swin The ing'lever t is provided with a member, e. g., a
roll u, which is acted upon by the printing machine at each printing operation by suitable means, such as an electromagnet. The shaft f of the feed wheel a carries a rotatable bell crank 9 .(Fig. 2) one arm of which slides with the pin 91 on the eccentrich, and the other arm termie nates in a toothed segment Q2. The leccentric h securedto a shaft p is driven by the feed wheel a by means of a back gear i1 and i2 (Fig. 5) at a ratio or, say, 135. One arm of the bell crank which also serves as driver for the claw k1 by striking this claw andcarrying it along when the gripper returns to procure a new strip of paper andhas been opened. A braking lever a: loaded with a spring w rests on the edge of thedisc v m In the first place, it
andhas a double effect. brakes the claw k1 until the gripper opens, owing tothe rotation of the claw k2, and the screw on the shaft Z drives the claw k1; and it further limits the motion of the claw 121 when the gripper turns back to grip a new strip. Speaking more accurately, the lever :13 holds the claw In for a short time during which period the claw k1 continues to rotate. In this way, the gripper in kg opens to be able to catch the ends of the paper strip m.
The strip m is fed from a reel over two rollers 11.1 and 112 and shears 01 and Oz to the gripper k1 R2. The roller n1 is continually driven from the main shaft f or the feed wheel a by the pinion n, and the other roller n2 is disposed on an oscillating lever and periodically pressed against the continually rotating roller m by the eccentric 1' arranged on the shaft p. The result is that the paper strip m is caught only periodically by the rollers m and m and moved forward, the strip remaining stationary during the cutting step. -A third eccentric q secured to the shaft p moves the cutting device 01 and O2 in such a way that a strip of desired length is out off. The device is provided with a counter s from which the total number of sheets deposited can be read off.
The device functions as follows: a
Assumed the feed wheel a has 100 teeth, and it is desired to insert a tab after every 250 sheets. The distance between the rotary axis 251 and the pin d1 on the lever 25, d is first adjusted by-mea'nst of the screw e, e1, so that the pawl c, ateach swinging motion of the lever t, d, will move the a feed wheel a to the extent of two teeth} 'When the lever t, d has therefore been actuated 250 times, or 250 sheets have been eject,ed,;by the printing machine, the feed wheel a will have com-- pleted five revolutions. feed wheel a the sliding pin 91 secured to one arm of the freely rotatable bell cranky lies onthe eccentric h secured to the shaft p which is driven a from the'shaft at'a ratio of l:5, so that the shaft 12 completes one revolution to every five of I the shaft 7. By. means of the eccentric h the sliding pin 91 is moved outwardly, and the toothed segment g: on the'other arm of the'bell crank ,y will thus rotate the pinion on the shaft Z carryingthe'two gripper claws hi and k2, the
latter one of which being firmly connected with the shaft 1 by means of clamping screw. The
shaft] will rotate, owing to the action of the bell crank g and the toothed segment 92; Duringjthis rotation of the shaft 1, the rotation of the disc 1;
'andthus of the claw in will be stopped for a distance by the action of the braking lever 1:, so that the two claws In and k2 form a jaw opening towards the paper strip m (Fig. 3) In the' mea'ntime, the eccentric 7' has pressed the roller :12 against the roller m and thus slowly moved the strip m until the latter projects intothe' jaw formed by the gripper claws k1, k2 Thefeccentric q secured to the shaft p will then abut against theknife 02, press it against the top knife 01 and thus cut off a'strip of paper. In the meantime, the sliding pin g1 of the bell crank g has advanced on the eccentric h to a point hl permitting'approach to the shaft 10, so that the pinion on the shaft Z will slightly turn back to provide for the During motion of: the

has caught the cut paper strip, through an angle exceeding 180,and the gripper will then place thestrip on the pile of sheets and open, whereupon the operation cycle will begin again.
