VISIBLE-CARD-FEEDING MECHANISM.

application filed June 25, 1926. Serial No. 118,510.

The present invention relates to card-controlled machines and equipment related thereto, and more particularly to an improved card feeding mechanism.

In card-controlled and card punching machines,.(as well as other machines to which cards are fed) in present-day usetrouble and delays are caused by the failure of cards to enter the card passage of such machines correctly aligned and consequently being out of register with the analyzing pins there is, in some cases, incorrect analyzing where the machine is a tabulator, wrong punching where the machine is a punch, and often jamming and interruption of the feeding.

Also no provision is made in such machines for inspecting the cards or reading the data thereon while the cards are being fed to the machine which is .to operate upon them.

Some of the objects of the present invention are to provide an improved card-feeding mechanism for record cards; to provide means for automatically delivering cards to a machine in accurate aligned relation for correct registration in such machine; to provide means whereby each card can be inspected just rior to its delivery to the machine whic is to operate upon it; to provide a delayed feeding mechanism forl record cards whereby the rate of card travel is varied to cause cards to pass an inspection point so that data thereon can be intelligently seen 3 to provide means, operative between a card receiving machine and the magazine from which the cards are fed, for rendering each card visible for inspection purposes;

to provide means exposing each card of a series of cards to view during the feeding of such cards and automatically interrupting the feed to allow each card to be inspected; and to provide other improvements as will hereinafter appear.

In the accompanying drawings Fig. 1 represents a sectional elevation taken longitudinally of a card punching machine including one form of the present invention; Fig. 2 represents a plan of the same; and Fig. 3 represents a section of the card tray looking toward the left, Fi ure 1.-

Referring to the rawings one form of the present invention is shown as incorporated in a punching machine of the keyboard operated type such for example .as illustrated in U. S. Letters Patent, No. 1,307,682,

for inspection prior to enterin and to which reference may be had for de talls not here deemed necessary to describe.

Generally considered such a machine comtively set by a travelling carriage 14 con taining generally one row of selecting pins 15 which are actuated by the operation of the keys 16 of a keyboard 17. Wires 18 or other suitable means transmit the movement of the keys 16 to the corresponding pins 15.

Operation of the die 11 takes place through the rocking of an arm 19 in timed relation to the cycle by a cam 20 of the main shaft or spindle 21. As customary in such machines, a card stop 22 is provided which rises to stop each card in registered position and falls to release each card after the punching operation, and is raised by a pivoted arm 23 having a roller 24 at one end engaging a cam 25 on the shaft 21, and lowered by a spring 26 stretched to the other .end of the arm 23 and serving also to hold the roller 24 in contact with its cam 25. The cards leave the punch passage 12 by reason of the upper and lower feed rolls 27 as will be understood.

In this type of machine, the cards are fed automatically one at a time from a magazine 28, in which they are stacked, by way of a throat gap or slot 30 throu h the action of a magazine slide 31 and pi er knife 32. The slide 3l'isarranged to be reciprocated actuated from the shaft 21 and connected to a rock arm 34 by which the motion is transmitted to the'slide 31.

For the purpose 'of presenting the cards the punch passage 12, a receiving tray 35 1s interposed between the card delivery side of the mag!!- zine 28 and the card receiving side of the passage 12, the position of the tray 35 being such that its card supportin surface 36 lies substantially in theplane o the so that its card delivery slot 3 re'glsters with the passage 12. The receivin side of the tray 35 is preferably spaced rom the assa e12 .in timed relation by a rod 33 eocentrically magazine 28 toaccommodate a pair of feed rolls 38 by which the cards are fed in the proper direction after leaving the maga-' zine 28.

In order to ensure correct alignment of .each card as delivered to the passage 12, that is to position the card so that its front or leading edge is at a right angle to its path of travel, the tray 35 is formed with walls 40 on its ends and card receiving side, and with a wall 41 on its card discharge side, the latter extending ,above the walls 40 to serve as a stop or abutment for the entering cards. The

walls

40 and 41 are arranged to conform to the shape of the cards and intercept the surface of the tray to bound a space which is substantially of the same dimensions as the card yet allows the card to seat readily therein; Also the walls 40 slope upwardly and outwardly as shown at 42 with a rather even curvature so that each card is guided and settles naturally into its aligned position upon the tray 35. The upper portion of the wall 41 is likewise sloped as shown at 43 so that the front edge of the card, when it is in more elevated position than the cards usually take, rides down its face to take its correct position.

In thepresent construction, the plane of delivery of the cards from the feed rolls 38 is slightly above the juxtaposed side wall 40 of the tray 35 in order that the cards, upon leaving the feed rolls 38,'can be properly delivered to the tray'35, their projection beyond the tray being prevented by the wall 41.

. In order to deliver each card from the tray 35 to the passa e 12 of the punching mechamsm, a trans er knife 44 is provided to project through slots 45 extending-transversely' across the bottom of the tray 35 and receives its motion from links 46 connected to a rod 47 which is oscillated by a rocker arm 48 controlled by-a cam 50 upon the main shaft 21. In rest position the transfer knife 44 lies' just behind the rear edge of a card in the tray 35 so that its actuation ejects or feeds the card out of the tray.

The operation of the device in the resent form of the invention is as follows: t e machlne 18 3.3 rest while the operator makes the punch set up by actuatin the keys 16 and when this is completed t e machine is started ,to make one revolution of the main shaft 21. The cams on this shaft time the movement of the card stop 22 to locate the card which has been ejected from the tray 35 by the tuned action of the transfer knife 44, and the die 11 uses to perform the punchlng step and falls to allow the dischar e of the perforated card. The timing 0 the transfer knife 44 is such thatit reaches its return or rest. position near the end of the punchlng cycle before the nextcard ejected rom the magazine 28 falls face upinto inspection positionin thetray 35. The operais completed the machine is started and the transfer knife 44 projects the card into the passage 12 Where it is gripped by the intermediate feed rolls 27 and brought agalnst the card stop 22 which has been raised to its operating position.

Having thus described my invention, I claim:

1. A card feeding mechanism comprising a magazine for cards, means for feeding said cards from said magazine in the direction of a card machine, and immovably means between said magazine and said machme for temporarily arresting each card for inspecp tion purposes.
