16? Claims.

invention relates to pin type. strip. feeding, devices,v and. more particularly to a. retractible pin type strip feeding device in which the individual, feeding pinsare simultaneously withdrawn or." retracted within the periphery of the feeding device.

Positivepin type stripf-eedingdevices. 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 av specified point. In the second type, the pins. arefixed 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 resilient mounting for: the individual pins, movement of which mounting. simultaneously retracts. all. of the: pins within the periphery of the pin. wheel, or simultaneously projects.- all ofthe: pins. therefrom. During. certain: periods of use of such positive pin type strip feeding devices it is desirable to. retract. all of. the pins within the periphery of thefeeding device where. they will be concealed and out of. the; way. Here. tofore, all applications requirinaperiodic move.- ment of the feeding pins to inoperative:- position necessitated thereciproca-ting type of pin wheel.

The present; invention provides a positive. pin type feeding. device incorporating not only all-f the advantages of. a fixed: pin. type of feeding de. vice, but all the further advantage." of a. construction permitting the complete retraction of all the pins within the surface of the feeding. device when. such withdrawal or retraction isv desired in connection with: the particular; use. to: which the. strip. feeding device is put;

The object of the present; invention. isto simplify the construction: as; well as: the means and modev of operation ofa pin. type. feeding device as disclosed herein, whereby such devices may not only be economically manufactured but will be more. efficient and satisfactory inuse, adaptable to a wide variety of. applications, having relatively few parts and be unlikely to getout of repair.

A further object of the. invention is to; provide a pin type feeding device inwhich the pins; are. both. movable and resiliently mounted. so that they may be either extended or retracted relative to. thesurface. ofv the feeding device A further object of the invention, is toprovide. in.- a pin type feeding deviceof the character described, a simple andefficient means of simulta: neously adjusting all of the individual pins from operative to inoperative position and viceversa.

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

A further object of the inventionis to provide. an oscillatory control member for theindividual resilient mountings for simultaneously adjusting the individual pins relative to the. periphery of the strip feeding device.

A further object of the invention is to provide a pin type. feeding device possessing the advan tageousstructuralfeatures, the inherent meri toriou-s characteristics and the mode of operation herein mentioned.

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

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

lfteferring to the drawing, there is shown in Fig. 1. an assembled strip. feeding device embodying thepresent invention. In this form, thefeed s... dev c mpr s ng a pin carry body I. is secured to a rotary; supporting shaft. 2 for unison.

feeding device.

rotation therewith by a key 3 having a press fit within the body and engageable within an aligned complementary keyway within the periphcry of the shaft The body i is mounted for longitudinal sliding motion upon the shaft 2, it being retained in adjusted position thereon by means of a latch d, pivotally mounted to the body at 5 for removable engagement within a selected notch 5 on the side of the supporting shaft 2.

A series of individual feeding pins 1 are slidingly carried within individual grooves 8 arranged in radially spaced relation about the main body i. As shown in Figs. 5 and 6, the pins 1 are mounted for radial reciprocatory movement into and out of the supporting body I. When extended from the periphery of the body I, the pins l engage spaced perforations in a record strip a to advance the strip in unison with the rotation of the strip When the pins are withdrawn as in Fig. 6, the strip may be advanced by other feeding means.

The pins '5 are retracted and expelled relative to the body l by rotary adjustment of a control knob H3 supported by the body I intermediate a centrally extending hub portion 5! of the body and a peripheral flange i2 thereof. The knob H3 is maintained in position relative to the body I by means of a nut i3, recessed within the knob and having threaded engagement with the end of hub portion ii.

concentrically arranged upon the inner surface of the knob to is a series of holes i l (Fig. 7) through which extend ends iii of flexible resilient mounting wires 16. The opposite ends H of the wires it are seated within the ends of the individual pins l in axial alignment therewith. The mounting Wires are free to oscillate within the holes M upon rotation of the control knob id.

Referring to Fig. 5, counterclockwise rotation of knob is from the position shown therein to the position shown in Fig. 6 retracts the resilient wires it and with them the individual feeding pins 1, the wires it being in effect wound about the hub H in a tight spiral. Such movement of the support wires is permitted by freely mounting the wires i *5 in the retaining holes i l for limited oscillatory motion. Upon rotation of the control knob I ii in a clockwise direction, the resilient wires are immediately expanded, thereby pushing the pins f outwardly or upwardly relative to the periphery of the body I.

To locate the control knob It in either of its adjusted positions, there is provided in the extending flange it a pair of indexing holes 18 and is, representing respectively operative (extended) position and inoperative (retracted) position of the pins 1. Cooperating with the indexing holes i8 and i c is a spring biased plunger 28 carried by control knob is so as to normally project from the periphery thereof. Movement of the plunger 2b is controlled by a projecting finger operated stud 2| extending through an elongated guide slot 22 adjacent the periphery of the control knob Iii. Upon depression of the stud 2!, the plunger 25 is Withdrawn from either indexing hole It or iii, whereupon control knob I0 is free for rotative movement relative to the body I to either extend or retract the feeding pins l.

Control knob so is removable from the unit for servicing and the like by removal of the nut IS. A pair of recesses 23 are provided in the outer surface of the nut for engagement of a spanner wrench therewith to facilitate such removal. Upon withdrawal of control knob H3, however, the inherent resiliency of the pin supporting wires it results in immediate disarrangement thereof upon being freed of the restraint imposed by the knob to and its retaining holes it. To prevent such disarrangement and facilitate the reassembly of the unit, an auxiliary anchoring ring 24 is passed over the ends id of the support wires l6, thereby maintaining the wires in proper spaced relation for engagement by the knob it. Such auxiliary anchor ring is supported by the Wires and is positioned immediately adjacent the inner face of control knob it in contacting relation therewith when the unit is assembled. See Fi 4.

The present structure presents a relatively simple, but nonetheless efficient and satisfactory means of resiliently and individually mounting a series of feeding pinsfor simultaneous movement either into or out of the periphery of a pin supporting body. For other means of achieving a substantially similar result by use of another structure, reference is made to copending application Serial No. 138,226, filed of even date herewith.

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 without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into efiect.
