The front panel 22 is shown having a selecting lever guide 24 secured on the outer surface thereof with slots, such as 25, formed therein to permit movement of the selecting levers, such as 26, which levers are used for selecting any pair of complementary spindles of which there are two main groups. One group of spindles are referred to as the holding spindles, are given character references from I to 8, while the complementary set of spindles, referred to as pulling spindles,

are given character references IA to 8A, respectively. There is a complementary sliding lever 26 for each of the cooperating pair of spindles,

given character references IE to 83, respectively.

For example, operation of the lowest selecting 'lever B shown in Fig. 1 would simultaneously cause holding spindle l and pulling spindle i A to be urged upwardly through their respective aper tures in the front panel. There is one aperture in the front panel for each of the holding spindles of which a representative aperture 21 is shown 'in Fig. 3.

Thefront panel, likewise, has formed therein apertures 28 which are in the form of transverse slots to permit lateral movement of the pulling spindles, such as 3A, shown in Fig. 1.

Referring particularly to Fig. 1, there is shown an end adjustment guide 29 and a bottom adjustrow of holding spindles l to 8, respectively. The

bottom adjusting guide 30 is used to lower and raise the stack on the inclined front panel 22 so that the holding spindles and pulling spindles -will be properly aligned with their respective holes or slots for proper selection and sorting of the forms.

The pulling spindles IA to 8A, respectively, are

'carried by a movable carriage 3| supported in a 'slidable carriage cradle 32 between opposing angular cradle guides 33.

The operating lever 34 when moved downwardly as shown by arrow X will cause the carriage to to each of the selecting levers, is secured to the bracket with the upper portion being bent to permit said guide plate 38 to be secured to the upper surface of the bracket by means of screws, such as 39. There is a plurality of apertures formed in the upper portion of the latch guide plate 38 to permit the holding spindles to be movably inserted therethrough. The lower portion of the latch guide plate 38 is secured to one side move to the right as may be seen in Figs. 1 and 3, so that any one or more of the pulling spindles will likewise be caused to move to the right 'and withdraw the corresponding selected forms from the stack, as shown inFig. 1. At the completion of the downward movement of the operating lever 34, a spring 35 (Fig. 3) causes the carriage 3| to be moved to the left or restored to its normal position, and the operating lever 34 The operation of any one of these selecting Therefore, the operation A bracket 36 is secured in an inclined position between the base and back portions of the suption of the front holding spindles, such as hold-- ing spindle 5, shown in Fig. 3,

A latch guide plate 38, having a plurality of elongated slots therein, one slot corresponding of the bracket 36 by means of screws 40. The lower ends of the latch guide plate 38 are bent inwardly to form stopmeans 4! for the spindle latch 42. The lower end of each of these spindles has a reduced portion 43 which has the spindle latch 42 secured thereon and with a rubber stop 44 frictionally held on the end of each of the reduced portions 43.

An expansion spring 45 is movably disposed on each of the holding spindles with the upper end of the spring engaging the bent portion of the latch guide plate 38, while the lower portion of the spring engages the upper surface of the spindle latch 42. The purpose of the spring is to normally hold the spindle in its retracted or inoperative position, as shown in Fig. 3.

The rubber stop 44 engages the guide pin control bar 46 and is intended to provide noiseless contact for engagement with the guide pin control bar 46. The latch bar 41 has a pair of slots 48 formed therein to permit headed studs 49 to be inserted therethrough and secured to the bracket 36, to permit lateral motion of the-latch bar.

A spring 53 has one end thereof connected to one of the studs 48 (Fig. 4) with the opposing end thereof connected to a flange 5| formed on the latch bar. Latch tongues, such as 52, having camming surfaces as shown, are formed on the lower portion of the latch bar with one tongue being positioned for holding each of its respective spindle latches '42. When the guide pin control bar 46 is moved upwardly, the rubber stop 44 is engaged by said control bar and urges the spindle latch 42 upwardly until it engages the camming surface formed on the lower portion of the latch tongue 52, causing the latch bar to be moved to the left, as shown in Fig. 4, until the spindle latch 42 slides off of the camming surface and rests on the upper portion of the latch tongue 52, at which time the latch bar 41 will be urged to the right (Fig. 4) under influence of the spring 56 to cause the spindle latch to be retained in its uppermost position and locked in this uppermost or operative position by the latch bar.

: then each spindle, as it is moved, will release the preceding spindle so that only the last actuated spindle will remainin the upper position. However, if for any reason it is desired to restore all of the holding spindles to their normal inoperative position, the latch bar release 54 may be pressed inwardly to cause operation of the latch bar and thereby release any spindle or spindles 5 so that they restate their normal operating positibn:

The latch guide p1ate-3'3'forth'eholding spindles and'thepulling spindles has theslots for the spindlelatohes open to the-bottom thereoi so that the guide pin control bar @6' may engage the-lower end of both-the holding spindlesian'd the pulling spindles with the'upper portion of opposing ends of theguide pin control-bar being inserted inthe slots provided for the spindle latches to'act a's-a guide meanstherefor. Each of the selecting levers 2B is l '-'shaped,having-one end thereof terminating in a handle portion -55, whichextends throughthe slots" 56" formed in the" selecting lever guideM. The opposing: end of eachof said-selecting levers=is 'pivotally' connected by a pin 51*to theguide' pincontrol bar somewhere in the middle portionthe-reof approximately asshown' vin-Fi'g. 3; A stop pin 8 4 is secured to each of the-selecting levers 2S and affords a-limitin'g-"means for the left end of each of theguidepincontrol bars-d5. A rubber stop 58 is piaced on the lower portion of the carriage 32-so-that ail of'the-gu'ide pin control bars at will noiselessly engage and-rest thereon when the control bars are in the-position as shown in Fig. 3.

A shaft 59 has'o'pposing ends thereof-heldby a pair of arms Bil-which areformed on the leftside 0f the bracket 36; Cotter pins Bi' are used on opposing end of the shaft; on the-Router surfaces of the arms SE to hold the shaft=59 in place. Spacers-62 (Fig; 6) are positioned be'tween'the adjacent selecting'levers 265110 properly position and align said selecting-levers inthe machine; The selecting levers as are freely movable on the shaft 59, and under influence of springs =63'whioh are connected to the supportingstructure and the selectinglever 2E, assist in returning the selecting levers 26 to the normal positionas shown in Fig. 3, at which time theguide pin control bar- 46 is also returned to its normal position by gravity actuation, assisted by the influence of the spindle springs such as-45. There is one spring,

suchas 63; for each of the-selectingleverszfi.

Thecarriage 3| has channel-portions E4 formed longitudinally on opposingsides thereof-,andeach of said channels ,rideson its-respective guide-rail 65 a tokeep the carriage properly aligned and to permit-said carriage *to be moved-fromleft to right so-that the-pulling spindle or spindles may be moved in their transverse slots 28 during-the sorting and separating operation.

Further, there are adjustment guides for engagement with one edge of the stack of forms and for engagement with the bottom of the stack of forms. vBoth of said adjustment means being variable positionally to adapt them to the particular forms to be separated. It is also pointed out that the inclination of the front panel while shown at one angle may vary'in difierent adaptations of the machine, depending upon dimensional characteristics of the sheets or forms to be sorted or selected.

Further, from the foregoing, it will be seen that the machine for sorting and selecting forms utilizes a holding spindle mechanism and a pulling spindle mechanism, each of which has a plurality of spindles. Any pair of spindles consisting of one of the holding spindles and a complementary pulling spindle maybe simultaneously operated by a selecting means which operates a control bar for urging the said pair of spindles upwardly to an operative position for .engaging the forms selected to permit the pulling spindle to at least partially withdraw the selected forms from the'stack of forms. The selected forms which may be selected by the simultaneous operation of two or more .of the selecting levers permits multiple operation for sorting and selecting the particular forms or groups of forms desired. While the drawing of Fig. 1 shows the selected forms partially withdrawn from the stack of forms, it is to be understood that the selected forms may be completely withdrawn from the stack of forms, de-

pending on the physical characteristics of the forms and/or the physical characteristics of the machine embodying the invention. The inclined supporting member or front panel 22, objectively set forth, is actually a loading rack or platform which may have any angular inclination or tilt to facilitate and assure proper registration or alignment of the apertures, such as slots and perforations in the forms, for the insertion of the holding and pulling spindles therethrough.
