STRIP FEEDING DEVICE Filed Jan. 12, 1950 INVENTO JOHN 2'. DAV/05f Patented Dec. 22, 1953 STRIP FEEDING DEVICE John '1. Davidson, Dayton, Ohio, assignor to The Standard Register Company, Dayton, Ohio, a

corporation of Ohio Application January 12, 1950, Serial No. 138,226

lIThis invention relates to pin type stripfeeding devices, and more particularly to a retractible pin type strip feeding device in which the individual feeding pins are simultaneously withdrawn or retracted within the periphery of the feeding device.

Positive pin type strip feeding devices embodying a plurality of pin wheels are now commonly used and generally well known. There are two common types of pin wheel employed, one having reciprocating pins and the other having fixed pins. In the first type, the pins are progressively projected from within'the periphery of the wheel as it passes during its rotation at specified point. In the second type, the pins are fixed relative to the wheel, being in effect a solid integral part thereof and projecting from the periphery of the wheel throughout its entire periphery.

The present invention is related in a general way to this second type of pin wheel, but provides a means for simultaneously retracting all of the pins within the periphery of the wheel, or simultaneously projecting all of the pins therefrom. In certain applications pin wheels of the fixed pin type, i. e., a wheel wherein all ofthe pins simultaneously project from the periphery of the wheel, are quite satisfactory while using the positive pin type feeding means, but during certain intervals of use it is desirable to retract all of'the pins within the periphery where they will be concealed and out of the way. Heretofore in applications requiring a movement of the pins to inoperative (non-feeding) positions it has been necessary to use the reciprocating pin type of pin wheel.

The present invention. provides a positive pin type feeding device which has all of the advantages of a fixed pin type feeding device, and also the further advantage of a construction permitting the complete retraction of all the pins within the surface of the feeding device when it is desired to utilize other feeding devices. Thus the object of the present invention is to simplify the construction as well as the means and mode of operation of a pin type feeding device as disclosed herein, whereby such devices may not only be economically manufactured but will be more efiicient and satisfactory in use, adaptable to a wide variety of applications,.havingrelatively few parts, and be unlikely to. get out of repair.

.Afurther object of the invention is to provide 16 Claims. (01, 74-243) V a pin type feeding device in which the pins are I movably, mounted. so that they may be either extended or retracted relative to the surface of the feeding device.

A further object of the invention is toprovide in a pin type feeding device of the character described, a simple and efficient means of simultaneously adjusting all of the individual pins from operative to inoperative position and vice Versa.

A further object of the invention is to provide an oscillatory mounting for the individual pins.

A further object of the invention is to provide an oscillatory control member for simultaneously adjusting the pins upon their individual mountings.

A further object of the invention is to provide a pin type feeding device possessing the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein mentioned. H

With the above primary and other incidental objects in view as will'more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Referring 'to the accompanying drawing, wherein is found the preferred but obviously not necessarily the only form of embodiment of the invention,

Fig. 10 is a cross sectional view on line I!li0 of Fig. 5; and v Fig. 11 is a fragmentary view partially broken away of the bottom of the assembly shown in Fig. 5.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawing, there is shown in Fig. 1 an assembled strip feeding device. embodying the present invention. In this particular form the strip feeding device comprising a pin carrying body I is mounted for axial adjustment longitudinally of a rotary supporting shaft 2, the body I being locked in adjusted position by a set screw 3. Although being longitudinally adjustable upon the shaft 2, the body I is locked thereto for unison rotary motion therewith by means of a key '4 engageable in opposed complementary portions of a keyway formed in both the body I and shaft 2. The key 2 is retained against axial the body I (Fig. 4).

To control the pins I in their oscillatory move ment and maintain them in adjusted position is a collar 8 having a series of equally spaced lugs 9 extending axially therefrom toward the pin supporting body I. The spacing intermediate the lugs 9 is of such size as to permit the entry of a pin 1 therein. Thus, the individual pins I are each supported by the lugs s on opposite sides thereof, and by engagement with such lugs the positioning of the pin is controlled.

Collar t is supported for rotation upon draw nut Iil which has threaded engagement with an axially extending portion of the body I and bears not only upon the outer transverse face of collar 8, but also upon an interiorly projecting flange I I of the collar 8.

To oscillate the pin from operative position (Fig. 3) to inoperative position (Fig. 4) it is only necessary to loosen the draw nut It, and manually rotate the collar 8 a short distance thereby rocking the pins I upon their mounting studs 6. Rotary motion of the collar 8 is limited by engagement of the pins I with the lugs 9 on opposite sides of the pins as shown in Fig. 4. The collar 8 is locked in either operative or inoperative position by bringing draw nut II] into engagement therewith, thereby clamping the collar intermediate the draw nut Iii and body I with which the lugs 9 are in contact.

Should the collar 5 be moved axially of the unit an excessive distance, the lugs 9 would be withdrawn from between the pins I, thereby freeing the pins resulting in disarrangement thereof. To prevent this occurrence, the upturned flanges 5 of the key 4 are so spaced that the draw nut It cannot be loosened or moved axially of the unit a distance sufficient to permit withdrawal of the lugs 9 from between the pins I. Before such excess motion of the collar 3 and lugs 9 can occur, the draw nut It! comes into contact with the upturned flange 5 of the key 4, thereby limiting the axial movement of the draw nut.

Referring to Figs. 5 to 11, there is shown therein a slightly modified structure, which however embodies the same inventive concept heretofore described. bodily movable relative to their mount rather than being mounted for simple oscillatory movement as in Figs. 1 to 4, inclusive.

Referring to Figs. 5 to 11, inclusive, the pin wheel unit comprises a mounting hub I5 keyed to a rotary supporting shaft I6. As clearly seen in Fig. 9, the hub I5 supports in fixed relation In this form the pins are r by the lock collar 25 and extending supporting shaft It.

therewith a guide collar II, in the outer face of which is a series of angularly disposed guide slots I3 (Fig. '7).

The feeding pins it have a pair of studs 2@2I projecting from the shanks thereof in opposite directions (Fig. 9). The stud 28 extend within the guide slots I8 thereby controlling the path through which the pins I5 are moved. The oppositely directed studs 2| extend within an adjusting collar 22 rotatably mounted upon the longitudinally extending shank of hub I5. As will be understood from Figs. '7 and 9, movement of collar 22 causes a shifting of the bottom of the pins I9, thereby pushing the pins upwardly and outwardly, the pins being guided by studs 20 within slots I8, while the studs 2! pivot within collar 22.

The adjusting collar 22 has a plurality of recesses 232 i in its radial face contiguous to a lock collar 25. The recesse 23 indicate operative position of the feeding pins I9, while recesses 24 are indicative of inoperative position of the feeding pins I9. Cooperating with the recesses 23 24 are a pair of spring biased plungers 26 carried herefrcrn for engagement within the pairs of recesses 23 or 24. Overthrow of the adjusting collar 22 is prevented by shoulders 2? located on opposite sides of each pair/of recesses 232 i, the plungers 25 coming into engagement therewith should the collar be rotated too far. Lock collar 25 is fixed on hub I5 by set screw 28 which passes through hub I5 into frictional engagement with the periphery of the rotary Longitudinal movement of the pin Wheel assembly along shaft I6 is thereby prevented. Relative rotary motion between the lock collar 25 and shaft I6 is prevented by key 29 held in place by set screw 36. As shown in Figs. 9 and 11, the inner end of key 29 i provided with a laterally extending projection 3| which overhangs the edge of the lock collar 25 thereby retaining the key in position. The ad justing collar 22 is recessed to clear the projection 3| (Fig. 11) which recess also serves as an overthrow limit for the adjusting collar.

The entire unit is assembled with the adjusting collar 22 under sufficient pressure to create some frictional resistance to idle or free rotation thereof. The plungers 26 of course add additional resistance to rotation of the collar 22, thereby insuring that the collar will not slip or rotate idly during operation of the pin wheel unit. To adjust the collar from operative to inoperative position or vice versa, a spanner wrench is uti lized, notches 52 being provided in the periphery of the collar for engagement of the spanner wrench.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts wthout departing from the principle involved or sacrificing any of its advantages.
