2,809,829 STRIP FEEDING DEVICE Tom Turner, Dayton, Ohio, assignor to The Standard Register Company, Dayton, Ohio, a corporation of Ohio 7 Application October 28, 1954, Serial No. 465,351 Claims. (Cl. 271-2.3)

atent movement in feeding pin mechanisms of the kind described to a general utility.

Another object of the invention is to enable feeding pins in a movement as described to be set to operating and non-operating positions, it being contemplated that in the operating position thereof the feeding pins will occupy an erect position and that in the non-operating position thereof the feeding pins will be cocked or tumbled angularly from their operating positions.

A further object of the invention is to provide for angular tilting of the feeding pins for better feeding of a larger number of forms. In collating work, for example, multi-part forms sometimes are run in two sets and then placed together. With the pins tilted slightly forward giving a slightly hooked condition all of the parts of the strip can be collated at once. Also, in the event of a slight discrepancy in the printing of a set of forms a compensating adjustment can be made by tilting the feeding pins slightly one way or the other, realigning or reregistering the forms while they are being fed.

A still further object of the invention is to provide a generally new feeding device which is improved in respect of compactness and simplicity and which offers advantages of use, for example in that the pins may project a greater distance through and beyond the determined plane of the strip for greater feeding efiiciency.

A further object of the invention is to provide a strip feeding device embodying the advantageous structural features, the inherent meritorious characteristics and the mode of operation herein set forth, or their equivalents.

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, after described or illustrated in the accompanying drawings, or their equivalents.

In the accompanying drawing, wherein is shown one but obviously not necessarily the only form of embodiment of the invention,

Fig. l is a view in top plan of a strip feeding device in accordance with the instant invention, shown in connection with elements of an autographic'register or like machine;

Fig. 2 is a fragmentary view in side elevation, showing the pin feeding device of Fig. 1 installed in an autographic register or like machine and in an operating position;

as herein- "ice Fig. 3 is a view like Fig. 2, showing the feeding pins in a relatively tilted position; and

Fig. 4 is a view similar to Figs. 1 and 2, showing the feeding pins adjusted to a non-operating position.

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

Referring 'to the drawing, the pin feeding device of the invention is disclosed as embodied in a machine presenting a flat bed or table 10 supported on frames 11 and on which the strip material rests as it is advanced in a plane parallel to the table. In transverse underlying relation to the table 10 is a rotary shaft12 having its ends journaled in the frames 11. On the shaft 12 is a pin feed device 13, of which there may be two or more, having feeding pins extensible through an opening 14 in the table 10 to engage marginal perforations in the overlying strip.

The pin feeding device 13 comprises a disc 15 formed integrally with or suitably secured to a sleeve 16, the latter being mounted on the shaft 12 and secured thereto for unison rotation, as by a stake 17.

Spaced longitudinally along the sleeve 16 from the disc 15 is a control plate 18 rotatably mounted on such sleeve and having a hub 19. A retaining ring 21 acting on the hub 19 holds the control plate 18 from axial movement in one direction. The plate 18 is eccentrically disposed" on the sleeve 16, and, on that side thereof facing the plate 15, is a hub or bearing member 22. .The hub 22 is eccentrically disposed relative to the shaft 12 and to the disc 15 and is secured to the control plate 18 by rivets 23. Rotatably mounted on the hub 22 is a second disc element 24 having the shape of a ring and a circumferential series of holes 25 therein. I

The holes 25 receive pivot pins 26 on the base portions 27 of feeding pins 28. The opposite ends of the base portions 27 are connected to the disc 15 by pivot pins 29. Standing erect on said opposite end of each of the base portions 27, and in perpendicular relation to the

pivot pins

26 and 29, are pin portions 31. The feeding pins 28 are arranged in circular series and connected as described to cause successive pins progressively to enter, to

pass through, and to be withdrawn from the opening 14 of the table 10. Thus, the feeding pins have a circumferential area of projectionof the pin portions 31 which coincides with the location of opening 14. Moreover, it will be noted that the construction and arrangement of parts is such that the pin portions enter and leave the slot 14 along substantially straight line paths and so are similarly engaged and disengaged with respect to strip perforations.

The control plate 18 has an outer free end in which is located a fork or recess 32. A roller member 33 is received in the slot or recess 32 and a rod 34 is passed through the roller 33, in eccentric relation thereto. The ends of the rod 34 are received in curved slots 35 in the side frames 11, and one such end may conveniently be extended outside such frame for manual manipulation. The roller 33 and rod 34 tend normally to be a relatively stationary means, forming a part of the machine frame. So disposed, they prevent a rotary movement of the. control plate 18 about the shaft 12 and the controlplate and hub 22 thereon thus become reactant means about which the disc or ring 24 may freely rotate. It will be understood in this connection that the shaft 12 represents a means for action of the pin feeding device, the shaft being suitably turned or rotated intermittently by hand or by power means. The disc 15, being connected to the shaft 12 for unison movement, rotates with the shaft. Through Patented Oct. 15, 1957 3. allel' relation to one another throughout rotation of the discs:

Rotary adjustment of the shaft 34 serves to move the roller 33,, eccentrically in either. a clockwise or; counterclockwise direction. moves the control plate 18iarelatively slight distan'ce, as for-examplefrom the of Fig. v3. "In so moving, the control plate 18'through the hub 22'there0n depresses or rocks downwardly the. base portions 27 of.the-feeding ,pins 28, so tiltingjhe pinpoitions 31' thereof. In the illustrated instance the rotary motion'of" shaft 34has been in a direction to tilt the feeding pins to the rightas viewed in the drawing. Itiwill be app arent, however, thatj an opposite direction of rotary ad justment of? the rod 34'would result in an opposed or leftwardftilting movement of the feeding .pins.

Greater extremes Qfmovement'of'the control ,plate 18 are possib'le by a bodily. shifting motion of the rod 34; Thus, movementofthe rod '34from-the position shown in Fig. Zatthe bottom "slot 35' to the position shown in Fig 4 atthe top of the slot. effects a substantially-90 change in theposition of the hub 22" on plate 185 The feeding pins 23 are thus tumbledor cocked so that the pin portions 31* occupy a horizontal position parallel to the table and are. unable to enter the opening 14' therein.- It-may be said thatthe feeding pins or the feedingdeviceof which they, are a parthavebeen adjusted to'vary the circumferential area of projection of'the. pins. Withrespect toopening 14 and, the strip materialpassing thereover, it maybe said-,that with the rod 34 adjusted 'as seenin Fig. lthe pin'feeding device is in an operating position and that with'therod-adjustedas shown in Fig. 4 the pinfeeding-device is in a non-operating position.

From the above description" it} will be apparent that there is thusprovided'a device of the character, described of advantage before;

possessing the particular; featuresenumerated as desirable; but-which obviously is suscepti-bleof modification in-itsform, proportions, detail ,constructionand arrangement of parts without departing from the principle involvedor sacrificing any of its advantages.-

While in order to comply with the statute the invention has been described in language more. or less specific astostructural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction hereindisclosed comprise but one of the several'modes of putting the in vention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and, valid scope of the appended claims.

Having thus described my invention, I'clairn:
