11 Claims.

Thisi-nvention relates to improvements in statistical card machines andhas particular reference to-a card: feeding mechanism therefor.

object of the inventionisto provide an improvedmechanismwherein the feeding of cards, seriatim; from a stack maybe interrupted during the continuous operation of said mechanism.

Another object is to providefor the shifting of a continuously operable'card picker member between-inoperative and operative positions with respect to cardsto be-fedthereby-while said member is being operated.

A further obj-ect is to control the feed of cards from a stackiby-moving a. stop into the-path of acetate-positively prevent its-feed While the picker memberis-being continuously driven in its inoperative position and-by retracting said stop from saidpatlr-when said picker-member is ren-' dered operative to feed the cards. r

A still further object is to mount the'continuonsly operated cardpicker member for rotative movement upon the first of two telescoping elements, and toreciprocally drive thefirst element relative tothe second element and mount the sameandsaid picker member for movement, under control" ofsaid second element, to and from operative position relative to cards to be fed.

and c p ocates with th latt r, a so has secured thereto at 2.4 a cardsupportingplate 25. that con.-. stantly engages the lowermost card 1 and moves with-the head I] so as to reduce friction. as said cards are stripped, from; the stack.

The mechanism for controlling the lateral movements of, the two. heads I1 between operative. and inoperative positions will now be described,

This mechanism comprises a rock shaft 26 supported in

brackets

21 and 28 secured to the side plates 5, and said bracket 2? also has fastened thereto a solenoid 29 the operation of which may be controlled, by any desired circuit, to rock said shaft 26 and thereby accomplish the shifting of the picker heads ll from inoperative to operative positions, or vice versa. The core of the solenoid is joined to one end 30 of a lever secured on the shaft 26, the other end 3| of said lever being connected by a retractile spring 32 to the bracket 21 so as to rock the shaft 26 clockwise, when the solenoid 29 is de-energized, to shift the parts to the position of Fig. 4 wherein the picker heads are reciprocated in their inoperative positions. Secured to the shaft 28 directly above each picker head is an arm 33 carrying a pin 34 connected, by a spring 31, to one arm 35 of a bell crank 36 loose on said shaft. The lower extremity of the other arm 38 of said bell crank is pivotally connected to a head 39 secured to the upper end of the guide 22 so that motion transmitted to the bell crank 36 will be imparted to the head 39 to shift the guide rod 22 and, consequently, the head, I! between the inoperative and operative positions thereof. When the solenoid 29 is energized to move the heads H to their operative position of Fig. 3, the counterclockwise rotation of the shaft 26 will cause the arm 33 associated with each picker head to move in a similar direction and thus, through the tension spring 31, exert a pull upon the connected arm 35 of the bell crank 36 to turn the same on the shaft 26 so that the head 39 and guide 22 will be moved forwardly toward the cards with the result that each guide 22 will shift its associated head I! to engage the latter with the bottom card of the stack, whereupon reciprocation of the heads will strip said card and feed it to the rollers 9. After the head I! is engaged with the card, each arm 33 has a slight additional movement which spaces its pin 34 from the adjacent edge of the arm 38 of said bell crank 36, as shown in Fig. 3, and this additional movement places the spring 31 under sufficient tension so that it will have a tendency to constantly urge the picker head I? in the direction of the card and thus permit it, by reason of its rotative movement on the sleeve, to accommodate itself to any possible slight curvature in the card which it contacts so as to assure proper engagement of the picker knife 2| with the top edge of the card preparatory to feeding the same downwardly.

Upon de-energization of the solenoid 29, the spring 32 becomes effective to rock the

lever

30, 3| and the shaft 26 clockwise and this movement is also imparted to the arms 33 secured on said shaft so that the pins 34 will re-engage the arms 38 and rock the bell cranks 36 in the same direction to shift the guides 22 of the two picker heads I! to the position of Fig. 4 wherein said heads will continue their reciprocation in an inoperative position so as not to feed cards from the magazine.

During the reciprocation of the heads I! in their inoperative position itis desirable to positively prevent feed of the cards from the magazine which might otherwise occur by reason of the continuous reciprocation of the supporting plate 25 in contact with the bottom card of the stack. For this purpose there is provided two stop members 40 each pivotally mounted adjacent its lower end upon the casting l and movable into and out of the path of the bottom card in the. magazine. When the solenoid 29 is energized for the feed of said cards said stops are adjusted to their inoperative position of Fig. 3, and when said solenoid is de-energized said stops are adjusted to their operative position of Fig. 4. This adjustment of the stops is accomplished by a solenoid 4| mounted upon a bracket 42 secured to the casting I0 and having its core connected to one end of a lever 43 the other end of which is joined to a link 44 having a pin and slot connection 45 with the upper end of one of the pivoted stops 43 which, in the illustration, is the one shown in Fig. 3. The lever 43 is secured to one end of a rock shaft 43 supported at the rear of the casting I0 and the other end of said shaft has fixed thereon an arm 4'! to which is connected a link 43 like the link 44 and similarly connected to the other stop 43. With this construction, motion imparted to the lever 43 to operate the stop 43 shown in Fig. 3 is also transmitted through the shaft 45 to likewise control the other stop 40.

Energization of the solenoid 4| is controlled by any desired circuit and occurs simultaneously with the energization of the solenoid 29. When so energized, the solenoid 4| rocks the lever 43 and arm 4? counterclockwise and through the links 44 and 48, adjusts the stops 40 to their inoperative position. A spring 49 connecting the iever 43 with the bracket 42 is placed under tension by the energization of the solenoid 4| and upon de-energization thereof acts to rock the lever 43 and arm 41 clockwise. Tension springs 38 and 5| (Fig. 1) connecting the lever 43 and arm 47 with the upper ends of the stops 40 act, upon de-energization of solenoid 4|, to assist in the movement of the stops to their operative position beneath the lower edge of the bottom card in the stack and thus prevent any possibility of it being fed from the magazine while the picker heads are reciprocating in their inoperative positions.
