4 Claims. (01. 2n-'-s4) The present invention relates to sorting machines of the type employed in connection with the sorting of cards used in tabuiating machines such as, for example, the well known Hollerith type of machine.

The invention contemplates theprovisionof a sorting machine wherein two or more sets card receiving pockets are arranged in superimposed relationship in the same machine framework and in which the various operative machine parts, such as card impelling rolls, analyzing devices, and picker mechanisms are all driven from a common'driving motor.

According to the present invention, it is contemplated that the use of superimposed sorting pockets shall materially conserve the space limitations of a single sorting machine of conventlonal design capable of accommodating the same amount of work, as well as to eliminate considerable waste motion on the part of the operator. In such an instance, the superimposed sets of cardreceiving pockets are served from a single card hopper by a single analyzing mechanism and by a single picker and feed mechanism. A sorting machine of this type is admirably adapted for use where alphabetic or alphabetic and numeric sorting operations are resorted to, especially the former.. .In suchan instance, a very material saving in space and in the distance the operator is obliged'to travel to service the machine during v-ope'ration is-obtained. I I -:The provision of a machine of this character 'which is-extremely simple in its construction, one by. means of which it has been possible to eliminate a-large'number of moving parts, one which consequently. is unlikely to get out of order, one

i which is {rugged and durable, one which may be manufactured at a low cost, one which'is of pleasing appearance and design, and one which otherwise is well adapted to perform the services re-- quired of it, are further desiderata that have been borne in mind in the production and development of the presentinvention.

The provision or a machine such as has been briefly outlined above being the principal object of the invention, other objects of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, theprinciple of the invention and the best mode. which hasbeen contemplated, of applying that principle.

In the accompanying drawings forming a part or this specification two embodiments vention have been shown.

or the in- Fig. 4 is a sectional viewv taken substantially substantially along the line 4-4 of Fig. 3.

Fig. 5 is. a sectional view taken along the line 5-E of Fig. 2.

Figs. 6 andGa are detailed views, somewhat schematic in their representation, showing the forward ends of the chute blades as viewed from go the section lines 6-6 of Fig. 5. In these views legends have been applied to illustrate certain principles associated with the invention.

In all of the above described views, like characters of reference are employed to designate like gs parts throughout.

Referring now to the drawings in detail and particularly to Fig. 1,v the. sorting machine'involv'es in its general organization an upper tier 2M and a-lower tier 292 of sorting;' pockets it. These two tiers arearranged in thevmachine framework in-superimposed relationship and are served by a single card magazine or feed hopper 82'. The feed hopper $2 is adapted to receive therein a stack 83' of record cards with a card plate 86' resting on top thereof. A conventional picker-mechanism designated in its entirety at 88' serves to pick upthe cards in the stack 86' one at a time from the bottom thereof and feed them in'succession through an adjustable throat mechanism. 98'. from whence the cards are passed to a sensing mechanism-including a contact roll 92' and a sensing brush 94'. Thereafter the cards are admitted to a cam controlled'analyzing or distributing mechanism 96' by means of which selection of the .variouspockets is made.

Theanalyzlngor distributing mechanism 3% v j e per se forms no part or the present invention and reference may be had to my copendin application, Serial No. 744,144, filed April 26, 1947, for J Card distributing mechanism for sorting machines for a full disclosure of such a mechanism. Likewise, the picker mechanism 88' per se forms no part of this invention and reference may be had to my copending application, Serial No. 745,-

884, now Patent 2,464,569 filed May 3, 1947, for

I Card feeding mechanism for accounting machines for a full disclosure of this device.

The pockets in the upper tier are labeled, reading from right to left, R, (special character), A, B, C, D, E, F, G, H, I, J, K, L, M, N, 0, P, Q. The pockets in the lower tier are labeled, reading from right to left, R, S, T, U, V, W, X, Y, Z, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0. In the drawing in Fig. 4, the medial region of the machine has been deleted by broken lines and, as a consequence, certain of the pockets are not shown, but their existence should be apparent.

The hopper 82, picker mechanism 88. sensing mechanism 92', 94', and analyzing mechanism 96' form no part of the present invention and reference may be had to my above mentioned co-pending applications for a full disclosure of these instrumentalities.

Referring now specifically to Figs. 1 and 3,

upper and lower card supports 16' respectively provide respective superimposed card paths extending longitudinally of the machine. Each card path has associated therewith a series of chute blades, those blades associated with the upper card path being designated at 2H1, while those associated with the lower card path are shown at 2l2. Both sets of chute blades 2 l8 and 2 l2 are loosely disposed on the upper surfaces of their respective card supports and each blade is anchored at one end thereof by spot welding or the like to a respective support. These chute blades are relatively narrow, and are arranged in parallelism along the upper surfaces of their respective supports. The blades 2H] and 2I2 are of successive lengths and terminate at their respective card-receiving stations or pockets to direct the record cards thereinto.

The upper set of blades 2! are designed to accommodate the pockets labeled A to Q in= elusive, as well as the R pocket and .the special character pocket, while the lower blades are designed to accommodate the pockets R to Z inclusive and to 9 inclusive.

The lower blades 212 rest loosely upon the upper surface of the lower set of card supports 16' and are substantially straight throughout their entire length. Their forward ends terminate in the vicinity of the analyzing instrumentalities 86' (Fig. 3). These blades 2 l2, together with the supports 16, follow a substantially straight lower card path extending longitudinally of the machine.

The upper blades 2" rest loosely upon the upper card support 16' and are substantially straight throughout a major portion of their lengths but are curved downwardly as at 214 (Fig. 3), extend vertically as at M6 for a short distance and are curved as at H8 in such a. manner that the forward ends of these blades merge into the plane of the lower blades 2l2. Both sets of blades 210 and M2 terminate at their forward ends in the same transverse line across the card path in the vicinity of the analyzing instrumentalities 96'.

After the cards have passed the analyzing station and selection thereof has been made by the various chute blades 2l0 or 2i2, as the case may be, they are engaged by, a pair of feed rolls including an upper roller 228 and a lower roller 222, from whence the cards are conducted either directly rearwardly along the lower card path or of feed rollers 224, 226 and 228 are mounted on transverse shafts 282, 284 and 236 respectively. These shafts have their ends rotatably journaled in a pair of swingin rame members 256. These members 256 constitute the side pieces of a lad der-like framework unit or structure designated in its entirety at 258. The frame-like structure 258 invloves in its general organization, in addition to the members 256, a plurality of cross members or tiers 260, one of which is located adjacent the top of the framework and the other of which is located adjacent the bottom thereof. The members 256 are substantially of reverse s-shape configuration and the upper ends thereof are secured to a rock shaft 262, the opposite ends of which are journaled in blocks 264 secured to the front and rear plates 54', 56'. The rollers 224, 226 and 228 are designed for respective cooperation with a series of rollers 248, 221, and 228 carried on transverse shafts 242 extending between the front and rear plates 54' and 56.

At latch rod 268 extends across the lower ends of the members 256 and the extreme ends of the latch rod are formed with latching elements 218 which are designed for reception in respective latch plates 212 secured as at 214 to the front and rear plates 54, 56. An operating handle 216 is secured in any suitable manner to the latch rod 268 in the medial regions thereof and is designed for manipulation in order that the latching elements 218 may be secured in or withdrawn from the latch plates 212. From the above description it will be seen that the entire framelike structure 258 is capable of being swung about the axis of the rock shaft 262 from an inoperative position wherein the rollers 224, 226 and 228 are out of cooperation with their counterparts 248, 221 and 229, to an operative position wherein these various pairs of rollers are in close proximity to each other for card impelling purposes.

To provide a positive card path leading from the analyzing unit 96 to the path afforded by the pairs of rolls 18', 18', a plurality of stationary guide elements 218, 288 and 282 are mounted upon cross rods 284 and 286 extending between the front and rear plates 54', 56'. The guide member 218 is located adjacent the front of the framework 258 and the guide member 282 is located at the rear of the framework, while the guide member 280 is disposed centrally of the framework. These three guide members are substantially identical in shape and conform to the curvature of the card path. The guide members 218 and 282 are designed for cooperation with the lower edges of the side members 256, these latter members occupying a position in close proximity but slightly spaced from their counterpart guide members when the framework 258 is in its operative position. A central guide member 288 is fixedly secured to the cross tiers 268 and cooperate with the guide member 280 to provide a curved card path. The space existin between the various cooperating guide members repre- 5 sents the card path leading from the analyzer to upwardly along the curved card path leading to the upper set of card feeding rolls.

In order to securely hold the upper card blades 2l8 in their respective positions of parallelism, the shafts 232 and 236 are formed with central enlarged body portions 286 in which there are formed a series of annular grooves 288 providing a series of ribs therebetween. Each of the grooves 288 is adapted to receive therein one of the chute blades 2"], while the ribs serve to maintain the chute blades slightly spaced from each other. In a similar manner the shafts 242 are likewise provhorizontal card path for selective reception in the'pockets designated R to Z inclusive and to 9 inclusive. If, however, one or more of the chute blades 2H1 underlies any particular card leaving the analyzing stationli, this particular card will be guided upwardly along the path provided for it by the guides 218, 280 and 282, the card being j impelled by means of the positively driven rollers '20, 221 and 229. As the card reaches the upper regions of the framework 256, it will be engaged by the'rolls 18', I9 and conducted to one of the pockets designated A to Q inclusive.

The driving instrumentalities for the sorter are best illustrated in Fig. 1 and include a motor M mounted on a motor platform 22' suitably supported in the machine framework III. The motor M operates through a gear reduction device 42' to drive a belt H8 which passes around the puiieys I24 and I26 mounted on respective driving shafts H2 and '3' respectively. Additional pulleys I20 and I22 are mounted on the shafts i I2 and I I3 and constitute the driving elements of the upper and lower card impelling instrumentalities.

Upper and lower feed rollers 18', 19 mounted on transverse shafts 80', 8|, extending between the front and rear plates 54', 56', are driven by means of friction belts I24" and I36" respectively, these latter belts passing around the respective pulleys 620', M2, HI and I32. The upper belt passes over a pair of pulleys 300, 302 mounted on the shafts 2 12 outside of the framework at the rear oi. the machine to provide a positive cardimpelilng drive for the cards as they move upwardly along the path 2I8, M6 and 2 leading from the lower card line to the upper card line.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to a preferred embodiment, it will be understood that various omissions and substitutions and changes in the form and details of the apparatus illustrated and in its operation may be made by those skilled in the art,
