CORPORATION OF ILLINOIS STAGKING MECHANISM Application filed October 25, 1928.

The main objects of this invention are to provide an improved form of stacking mechanism; to provide a stacking mechanism having improved means for supporting a removable tray in position to receive articles from a guideway along which the articles are fed; to provide improved means for guiding the articles into the tray; and to provide a stacking mechanism of this kind which is particularly adapted for use in addressing machines for stacking stencil cards in removable storage trays at the ejecting end of the guideway.

An illustrative embodiment of this invention is shown in the accompanying drawings, wherein Figure 1 is a vertical central section of an improved stacking mechanism applied to an addressing machine.

Fig. 2 is a section taken on the line 22 of Fig. 1, and showing one of the detents for preventing backward movement of the cards.

Fig. 3 is a vertical section, taken on the line 33 of Fig. 1.

Fig. 4 is a fragmentary top plan of the improved stacking mechanism.

An improved stacking mechanism to which this invention is applied is adapted for use in connection with various types of machines but, in the embodiment herein shown, it is applied to an addressing machine. Inasmuch as the present invention relates partic ularly to the stacking mechanism, certain parts of the addressing machine not relating thereto and believed unnecessary to a complete understanding of the invention have been omitted from the drawings.

In the form shown, the improved stacking mechanism is applied to an addressing machine having a horizontal guideway along which the stencils and cards are fed in a stepb-y-ste'p movement to a printing mechanism, which is controlled in its operation by a suitable selector mechanism arranged to coact with the stencils.

An ejector is located adjacent the discharge end of the guideway and includes an oscillating arm or sweep movable through a quadrant and arranged to engage the stencils seriatim for sweeping them downwardly into an Serial No. 314,913.

upright position on a second guideway forming part of the improved stacking mechanism. Located adjacent the discharge end of the second guideway, is an improved support adapted to hold a tray in position to receive stencils directly from the second guideway.

In the form shown, the addressing machine comprises a frame 1 having an endless chain conveyer 2 provided with spaced lugs adapted to engage apertures in cards and stencils 3 for moving the cards and stencils edgewise along a horizontal guideway 4 formed by spaced guide rails 5 and 6. Suitable mechanism, not shown, is provided for moving the conveyor 2 step-by-step to feed the stencils seriatim to the printing mechanism and to the ejector at the discharge end of the guideway.

Adjacent the discharge end of the guideway 4, is a recess 7, to permit the stencil cards to be swept downwardly from the guideway 4 by an ejector 8.

In the form shown, the ejector 8 includes a sweep 9, which is pivotally mounted adjacent the rail 6, so as to permit the sweep to move downwardly into engagement with the upper face of a card. The sweep 9 is connected to a crank 10, which is adapted to be intermittently actuated by suitable mechanism for imparting an intermittent oscillation to the sweep.

The specific structural details of the guideway 4 and ejector 8 form no part of this invention and are more fully shown and described in application Serial No. 215,924, filed August 27 1927, in the names of Paul A. Gollnick, John J. Toolan and George Harred.

The sweep 9 is adapted to be rocked downwardly through a quadrant for sweeping the card from its horizontal position in the guideway 4 to an upright position in the improved stacking mechanism.

In the form shown, the improved stacking mechanism includes a horizontal guideway 11, and supporting arm 12 adapted to support a removable tray 13 in position to receive cards from the guideway 11.

The guideway 11 is located below the guide way 4 and is dispose at substantially right angles thereto. In the form shown, the guideway 11 comprises a bottom 14, and a pair of side walls 15 provided with rails 16 adapted to slidably support a vertical follower 17.

Formed at one end of the bottom 14, adj acent the guideway 4, is an arcuate approach 18, along which the cards 3 are swept by the ejector 8.

Formed in the side walls 15 adjacent the approach 18, are openings in which are pivotally mounted detents 19 having tips 20 adapted to project int-o the guideway 11 for securing the stencils against any backward movement upon the rip-stroke of the sweep 9-. Bearing against the detents 19, are springs 21 adapted to permit retraction of the tips 20 to enable the stencil to pass the detents upon the down-stroke of the sweep.

Located adjacent the outer end of the guideway 11, is a discharge opening 22, through which the cards 3 pass to the tray 13.

Arranged at the discharge end of the guide way 11, is an inclined runway 23 forming a continuation of the bottom 14 for guiding the stencils and cards into the tray 13 resting on the improved bracket arm 12, below the runway. Mounted on the walls 15 above the runway 23, is a pair of guides 24: adapted to engage the upper edges of the stencils for securing them against forward tilting during their passage down the runway 23.

The rails 16 extend beyond the runway 23, so as to permit the follower 17 to move outwardly a suflicient distance to enable the stenoils to travel below the follower. Outward movement of the follower 17 is limited by stops 25 formed on the extremities of the rails 16.

Slidably mounted in the tray 13, is a follower 26 which is adapted to be moved along the tray by the advancing stack of stencils.

The tray 13 is not connected to the runway 23, but merely rests upon the bracket 12.

In the specific form shown, the bracket 12 comprises an arcuate bottom 27 having side flanges 28 for retaining the tray on the bracket. Located at the inner end of the bracket 12, is a bearing or shoulder 29 for supporting the inner end of the tray. The

outer end of the tray rests upon the forward extremity of the bottom 27. The bottom 27 is curved so as to permit the tray to be slid rearwardly below the runway 23 and into engagement with the bearing 29. The bracket 12 is spaced from the runway 23 so as to permit the tray to be inserted between the runway and the bracket.

In operation, the stencils 3 are fed stepby step along the guideway 4 while the sweep 9 is oscillated intermittently.

Upon each down stroke of the sweep '9, a card is moved downwardly "along the approach 1'8 and is pushed past the detents 19 into a vertical position. Upon the forward movement of the cards 3, the follower 17 is pushed toward the discharge end of the guideway 11, and the cards move down the runway 23.

/Vhen the cards reach the lower end of the runway 23 they pass below the follower 17 and then enter the tray 13.

To remove or insert a tray, it is tilted to the position shown in dotted outline in Fig. 1 so as to enable it to clear the runway 23.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
