EDGE-PUNCIIED DATA CARD SORTER BRIEF DESCRIPTION In data processing there has long been a need for compact, low-cost equipment that can be used on an individual basis to quickly and easily sort data-punched cards. Many card sorting machines have been developed in the past. Some have been inexpensive and others have been easy and quick to operate. The conventional needle sorting machines are usually inexpensive to construct, for example, and provide effective sorting of many types of centrally punched cards, but they are slow to use. Other machines are faster and some will sort edge notched cards. However, so far as I am aware, there has not heretofore been available a compact machine that can be easily and economically operated at the user's desk and that will quickly and accurately separate one or more data processing cards that have been programmed by a particular notching of the card edges, from a deck of such cards.

Principal objects of the present invention are to provide a machine that can be built for a relatively low cost, in comparison to presently available machines; that is compact enough to be used at an operator's desk; and that will quickly sort edge-notched cards and separate out those code notched with desired information.

An alignment panel allows a selector to be set such that only those cards in a deck that have a sought-after code notching will be separated out.

Principal features of the invention include a rack that is resiliently mounted with respect to its housing so that a vibrator mounted thereon will vibrate the rack and any card supported thereby, without significantly vibrating the housing. A guide rack having notches corresponding to the notch locations at the edge of a data processing card and arranged to hold a representative or key card, cooperates with a selector that is moved with respect to the guide rack and that is positioned to correspond to notch positions in the cards to be sorted. Once the selector has been positioned, a knife-edge is elevated and the machine is operated such that cards having coded notches positioned immediately above the knife-edge fall from the deck to be separated from those cards held up by the knife-edge.

Other features include the special short, quick vibratory movements introduced into the frame through modifying the current to a conventional-type vibrator.

Additional objects and features will become apparent from the following detailed description and drawings, disclosing what is presently contemplated as being the best mode of the invention.

DETAILED DESCRIPTION Referring now to the drawings:

In the illustrated preferred embodiment, the invention includes a housing 10 having a front wall 11 and a rear wall 12, interconnected by sidewalls l3 and 14. Front wall I] is cut away at to provide for travel of a sliding selector, shown generally at 16.

A pair of parallel and horizontal slide rods 17 and 18 are each inserted through both end walls 13 and 14 and are welded or otherwise fixed in place. The rods 17 and 18 are highly polished so that tubular members 19 and 20, respectively, telescoped thereon, can freely slide therealong.

A leg 21 (FIG. 6) extends upwardly from the member 19 and a similar leg 22 extends upwardly from member 20. The legs 21 and 22, support a platform 23, having parallel, upstanding walls 24 and 25.

A pair of rings 26 are also slidably fitted over the member 20 and the rings are afiixed to an arm 28. As thus mounted, arm 28 can be raised or lowered, with the rings 26 then rotating around the member 20. A tooth 29 is affixed to the bottom of arm 28 and is adapted to fit into any of the teeth 30 of a rack 31.

Rack 31 forms the upper part of a frame 32 that also includes a backing plate 33 and upper and lower guide troughs 34 and 35, respectively.

Screws 36 and 37, passed through the ends of the rack and threaded into holes provided therefore in the end walls 13 and 14 support the frame in its set position.

A data processing card such as is shown at 38 (FIG. 1) will slide into the frame, with its side edges fitting in the guide troughs, until the numbers or other data indicating segments of one edge of the card are aligned with the grooves between teeth 30 of the rack 31.

Raising of arm 28 allows the members 19 and 20 to be moved along the rods 17 and 18 to a desired position and thereafter lowering of the arm will position tooth 29 in a groove between teeth 31 to fix the position of the sliding selector 16.

The sliding selector 16 further includes a bottom wedge 40 (FIG. 6) and an upper wedge 41, both arranged to travel between the upstanding walls 24 and 25. Wedge 40 has a pin 42 extending therethrough and the pin is positioned to reciprocate in oppositely positioned, horizontal slots 43 through the walls 24 and 25. A handle 44, fixed to wedge 40, projects through the cut away portion 15 of front 11, above the arm 28.

Wedge 41 has its inclined cam face 41a resting on the inclined cam face 40a of wedge 40 and has an elongate, vertical slot 45, through which a pin 46 interconnecting the sidewalls 24 and 25 is inserted. The top edge of wedge 41 is made horizontal, when the sorter is in its normal use position, and has a knife-edge 41b. As seen best in FIG. 6, pulling of handle 44 so that wedge 40 is moved toward opening 15, with pin 42 travelling in slot 43, will cause the inclined cam face 40a to act on the inversely inclined cam face 41a and thereby raise the wedge 41. The wedge 41 is held against longitudinal travel and is guided in its vertical travel by pin 46. Conversely, pushing of handle 44 to move wedge 40 away from opening 15 will allow the wedge 41 to drop.

With the arrangement above described, arm 28 can be raised and the selector can be moved sideways and be positioned, as desired, above the card 38, or along the rack 31. The arm 28 can then be lowered and tooth 29 will mesh with the rack to lock the selector against further sideways movement. Thereafter, handle 44 can be pulled to raise wedge 41 or pushed to lower it, all as will be further described.

A pair of boxlike spacers 46 and 47, having bottom support arms 48 projecting therefrom, are respectively welded or otherwise affixed to inner surfaces of sidewalls 13 and 14.

A vibrator plate 49, having upstanding end walls 50 and 51 (FIG. 5) and inwardly turned support frames, shown generally at 52, FIGS. 3 and 5) at the top thereof, is positioned to be supported on the bottom support arms 48 and between the spacers 46 and 47. The vibrator plate is separated from the spacers by resilient members 53, and bolts 54 inserted through the upstanding end walls 50 and 51, the resilient members 53 and sidewalls l3 and 14 have nuts 55 threaded thereon to secure the vibrator plate to the spacers. The resilient members 53 may be pads of rubber, or the like.

The inwardly turned support frames 52 each include parallel arms 52a and 52b extending inwardly from the upstanding end walls and a crosspiece 52c interconnecting the ends of the parallel arms. The crosspieces are each of small cross section and are positioned such that they will not impede upward movement of wedge 41 as it is moved upwardly therepast on either side thereof as the tooth 29 is positioned in adjacent notches of the rack 31. The arms 52a and 52b are spaced sufficiently far apart that the wedge 41 can move upwardly between them.

A vibrator unit 56 is fixed to the underside of vibrator plate 49, and when connected to a suitable power source, through cord 57, and, if desired, a transformer 58, (P16. 1) will operate to vibrate the entire plate 49. It has been found desirable to utilize the transformer since the current operation to the vibrator unit is thus smoothed out-resulting in more rapid, shorter vibrations that more effectively separates the cards. The amount of vibration, with respect to the housing can be regulated by the extent to which nuts 55 are tightened onto bolts 54.

A vertical plate 59 is fixed between the end walls 13 and 14, above one of the ends of the crosspiece 52c and one end of the wedge 41 and forms a barrier against which an outer card of a deck of data processing cards that is placed on the crosspieces 52c rests.

A pair of vertical sideplates 60 and 61 extend from the vertical plate 59 to form end guides for the deck of cards. Thus, they are positioned between the vertical plate and the rear wall 12, and generally above the upstanding end walls 50 and 51.

Another plate 62 is suspended between the vertical plate 59 and the rear wall 12 by a pair of crank arms 63 and 64 that are respectively fixed at one of their ends to blocks 65 and 66 at the top of the plate 62.

The other ends of the crank arms extend through elongate horizontal slots in the sidewalls and are threaded to receive knurled nuts 67. The threads are such that as the nuts 67 are tightened thereon the cranks are turned to pivot the suspended plate 62 towards plate 59. Thus, when a deck of data processing cards, such as is shown at 68, FIGS. 4a and 4b, has been placed between the plates 59, 60 and 62 and is resting on crosspieces 52c, nuts 67 can be released, plate 62 can be moved against the deck and turning of nuts 67 to tighten them will pivot the plate 62 against the deck to apply an increased compression thereto that tends to hold the cards of the deck in a slightly compacted arrangement. As so held, the cards are positioned such that the notches or spaces provided for notches in the sides of the cards are aligned with notches in the rack 31. As has been noted, the notches can also be in alignment with a reference card 38 held in the frame 32.

In any event, once the deck has been properly placed between the plates 59, 60 and 62, the sliding selector is moved sideways, as described, to a notch in the rack 31 corresponding to a notch representing particular data on those cards to be separated from the deck. The handle 44 is pulled to move wedge 40 and thereby raise wedge 41. The knife-edge 41b of wedge 41 will contact the lowermost edges of the cards of the deck and will raise the deck from one of the crosspieces 52c depending upon the positioning of the wedge 41 with respect to the centerlines of the cards.

Vibrator unit 56 is then operated to vibrate the vibrator plate and this vibration is transmitted through the crosspiece 520 on which they rest to the cards of the deck. This causes the cards to separate sufficiently for those having notches positioned above the knife-edge 41b of wedge 41 fall down, with the notch straddling the wedge and the card then resting on both of the crosspieces 520.

It is a simple matter to then hold the cards that have fallen while removing the rest.

With the present invention it is easy to sort edge-notched cards. The equipment is compact, not complex and can be made relatively inexpensively.

Although a preferred form of my invention has been herein disclosed, it is to be understood that variations are possible within the scope of the invention.
