This invention relates to stripffeeding means for advancing superposedwebs of manifolding` material or the like intov writing position .and more particularly to a pin type feeding and aligning device adapted to maintain the registry of superposed forms while in writing position. In the use of printed forms for manifolding purposes it is highly important and desirable that the forms be presented in exact alignment and registry at the writing position and equally important that they be so held while being inscribed.

To provide for unison advancement of the superposed strips of series connected forms from a, source of supply to the writing position the strips are marginally punched at spaced intervals for engagement of the pins or studs of a travelling pin type feeding member which may b`e either a rotary wheel or a travelling endless belt provided with studs or pins at spaced intervels corresponding to the spacing of the marginal feed holes in the strips.

Although great care is exercised in the manufacture of such marginally punched material wherein the marginal holes are punched in predetermined fixed relation with .succeeding printed forms, errors and ununiformity of spacing incident to inaccuracy of the feeding movement Aof the strips through the press and to ununiform stretch and shrinkage of the material, is quite likely to occur.

Such ununiformity of spacing of the forms and accompanying holes necessitates slight relativeshifting motion of the superposed strips as they approach the writing position. The necessary shifting motion is effected by the entrance of succeeding studs or pins of the pin type element into the overlapped holes of the superposed strips, which if not in registry will be brought into registry by the entrance of thestuds or pins. In order that the pins may enter the holes easily and afford clearance for such relative movement of the superposed strips as may be necessary, the holes are of larger size than the cross sectional area of the travelling pins. By their engagement with the forward margins of the holes the pins first advance one strip relative the other until the margins of the corresponding holes of different strips are in registry after which the strips are further advanced in unison. This is found a quite satisfactory and thoroughly prac-- tical method of aligning and registering the form of succeeding strips as they approach the writing position. However when arrested at the writing position the feed holes being larger than the pins there necessarily remains the possibility and opportunityfor the. forms to be acidrenlly Shifted out ofregistrywithewhf other duringthe writing operation. fichas-,heretofore beencus-k tornary to provideclamp bars, weights, ,ory other holding devices for preventingsuchslippage., The present invention provides for automatically retaining-the, aligned ,and .resisteredamns mmh relation -while-finvr writing position by providing in association with the successionof feeding pins.. of smaller size than the feed holes, an additional holding pin which by substantially fittingfthe reg-.g

istering holes of the vsuperposed stripsk willpref.' vent their relative shifting movement.

The object of the present invention is to improve the construction as well as the means -and mode of operation of pin type feeding devices for superposed strips whereby they may not only be economically manufactured but will be more efcient in use, automatic in action, uniform in operation, insure increased accuracy and be un likely to get out of repair.

A further object of the invention is to provide means for automatically holding the superposed forms in their aligned and registering relation which will engage the superposed strips after the corresponding forms thereof have been aligned and registered and which will release the strips preparatory to further relative adjustment of the strips as may be required to register the next succeeding set of forms. i

A further object of the inventionis to provide an improved pin type feeding device embodying in association with each other both adjusting and holding pins or studs. f l

A further object of the invention is to provide a pin type feeding device for use with marginally punched marial which during a portion of Vits travel movement will effect suchl relative adjust-` ment of superposed strips as may be required to bring them into registry and thereafter hold such strips in their adjusted relation. y

A further object of the invention is to provide automatic form holding means possessing the structural features of advantage and meritorious characteristics hereinafter mentioned.

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

Referring to the drawings, I is the cabinet or housing of a portable manifolding register having therein a compartment for a supply of interfolded continuous series-connected printed forms which are advanced from said supply compartment about suitable guides and over a writing tablet 2 forming the top of such cabinet into writing position beneath an opening 3 in the hinged lid or cover I of the cabinet I`. The record strips are marginally punched at 6 for engagement of .the pins or studs of a suitable' pin type feeding device which project through slots 1 adjacent one end of the writing tablet 2 into engagement with the marginal holes 6 of the record strips 5. Interleaved between the record strips 5 at the writing position is a length of carbon or transfer material 8 extending transversely of the record strips 5 and supplied from a roll 9 located at one side of the writing tablet 2. The pin type feeding device is actuated to advance the record strips i over the writing tablet by the rotation of an operating disc III which carries a crank handle II located at one side of the cabinet I.

In the present instance the feeding device comprises a pair of pin wheel units I2 mounted upon a shaft Il extending transversely of the cabinet I adjacent to one end thereof and to the extremity of which the actuating vdisc Il is connected. The pin wheel units I2 are of such size and so located that as they are rotated by manual rotation of the disc I l the radially projecting studs or pins I4 thereof are successively projected through the slots 1 in the writing tablet 2 and through the overlapping holes 0 of superposed record strips 5. Due to inaccuracies of manufacture, irregularity in the punching of the strips, or unequal expansion and contraction thereof, the overlapping holes C of the superposed strips may be slightly oil'set or in eccentric relation as shown at I5 in Fig. 'I. The feeding pins Il are of tapered or conical form and are of somewhat less diameter at their bases than the diameters of the feed holes i. Therefore such conical feeding pins I l will enter easily into the slightly offset or eccentric 75 holes l and by the engagement of the stud or pin with the margin of the hole of one strip in advance of that of the other strip, the strip first engaged will be advanced slightly until the holes are in conformity with each other beyond which point the strips will be advanced in unison by the continuous feeding movement of the pins. The differential size of the holes '6 and pins I4 and clearance afforded thereby-is such that after`having been brought into exact registry the superposed forms may be thereafter relatively shifted out of their registered and aligned relation within the limit of the clearance afforded by the increased size of the holes 6 relative to that of th pins o:- studs Il.

Ordinarily although not necessarily the pin type units I2 are so proportioned that a complete rotation of the pin wheel unit is necessary to advance the strips 5 one form length. Such being the case there is provided in association with the series of feeding pins I4 an additional holding pin or stud Ii the size of which is substantially equal to that of the feed holes 6. 'I'his additional locating or holding pin or stud I6 is brought into engagement with the superposed strips 5 at the completion of each feeding operation to hold the next succeeding set of forms stationary upon the writing tablet 2. 'I'he locating or holding stud or pin I6 will substantially completely fill the engaged registering hole 6 in the strip and by obviating any clearance between the pin or stud I6 and the margins of the holes will eliminate any shifting movement of'the strips relative to the pin or to each other, thereby maintaining the strips in their aligned and registered relation to which they have been previously adjusted by the action of the feeding pins I4.

It will be obvious that in the.event short length forms are to be fed or that the pin wheel unit I2` is so proportioned that it will advance the strips 5 the desired form length during a partial rotation of the pin wheel unit additional locating or holding studs or pins I6 may be provided at spaced intervals corresponding to the length of the form to be issued. In any event the construction and arrangement will be such that at the limit of the advance movement of the strips a predetermined distance a locating or holding stud or pin I8 of larger size than the feeding pins or studs I4 will be left in engagement in the registering feed holes 6 of the strips when the succeeding forms to be inscribed are in writing position upon the tablet 2.

Ihis construction'although extremely simple y and necessitating no additional parts is found to be quite effective and efilcient in stationarily holding the strips 5 during the writing operation, and possesses the advantage of being entirely automatic. It engages the strips at the limit of each advance movement and dlsengages the'strips at the initiation of the succeeding advance movement entirely without attention of the operator and without the manipulation of any control device.

While for illustrative purposes the invention has been shown as applied to a portable autographic register it is to be understood that the invention is equally applicable to pin type feeding devices of other mechanisms such as writing machines, computing and recording machines, imprintingv apparatus, pin type platens for typewriters, or other installation wherein it may be desirable to positively advance strips of material and hold such strips accurately in their advanced position while being operated upon. Although primarily intended for insuring registry and augment of superposed strips of record material of the manifolding assembly it is to be understood that the invention is not limited thereto, but may be employed for feeding single strips of material wherein it 'is desired to definitely locate the strip in a particular position of adjustment; asior example, in feeding moving picture film.

While for illustrative purposes, but with no intent to unduly limit the scope or application of the invention the locating pin I6 has been described as larger than the pins Il and engageable in a hole the same size as those engaged by the pins I4, it is to be understood that the same result may be achieved by making the pins I4 and I6 all the same size and varying the size of the holes 6 so that at the end of a form a hole of smaller size which will substantially fit one of the pins will be encountered thereby and such smaller hole lacking clearance will prevent the relative shifting motion of the strip.

Thus the same result may be had by varying the size of the holes for use with pins of equal size or by varying the size of the pins for use with holes of uniform size.

In Fig. 8 there is shown a fragment of record strip having therein a succession of spaced feed holes 6, one of which adjacent to each of the transverse weakened lines I'I on which the strip is. divisible into forms, is of smaller size as shown at 8a. For use with such strip having a succession of holes of dierent sizes there is shown in Fig. 9 a pin wheel the pins I4 of which are of uniform size, smaller than the holes 6 but substantially equal to the size of the smaller holes 6a. and the feeding pins permits relative shifting motion of the strip, while the engagement of one of the pins in a hole B'a, of substantially the same size as the pin will restrain such relative shifting motion of the strip.

For feeding short length forms, which are known as "split tickets the pin wheel unit may be provided with multiple larger teeth I6 as is shown in Fig. 10. If the Wheel has an even number of teeth the larger locating teeth I6 will be located diametrically opposite each other. However the length of forms and spacing of the feed holes which has been adopted as standard necessitates an uneven number of teeth in the pin wheel. Therefore it has been found expedient to provide two adjacent large pins I6 at one side of the wheel and a single large pin I6 at the opposite side of the wheel as is shown in Fig. 10. When the single pin is uppermost it will extend perpendicular to the engaged strips upon-the perpendicular diameter of the wheel. Upon a half rotation of the wheel the pair of pins I6 will be uppermost but the Wheel Will come to rest with the pins disposed at opposite sides of the perpendicular diameter of the wheel. The purpose and function of the pins, and the result accomplished is the same as before described.

. 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 suceptible of modiflcation in its form, proportions, detail construction and arrangement of parts `without departing from the principle involved or sacrificing any of its advantages. 4

While in order'to comply with the statute, the invention has been described in ,language more or less specific as to structural features,

The difference in the size of the holes 6 it is to be understood that the inventioin is not limited tothe specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention 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. y
