Application July: 21, 1941, Serial N0. 403,311 Claims... (01. 197 133) This inventionpertains to strip feeding and aligning devices for manifolding assemblies and 5 more particularly to a demountable attachment k for a writing or imprinting apparatus for advancing superposed strips of continuous series connected printed form stationery past the impres--- sion receiving position thereof and arresting. the strips with corresponding prescribed record re- 1 ceiving areas thereof in registry with each other and with the imprinting position of such apparatus.

The use of continuous series connected printed form stationery on typewriters, tabulatin'g, bookkeeping and addressing machines and analogous recording apparatus has become quite general. Such writing and imprinting apparatus is ordinarily equipped with .frictional feeding means for the record material and a rotary platen about which the stationery is advanced thereby.

However, modern commercial requirements, and

use of printed form stationery having restricted imprint receiving areas, necessitates positive control of the stationery and its arrest with preapparatus already in use, by which such machines may be adapted to alternate feeding operations.

A further object of the invention is to provide a pin type feeding attachment for writing and imprinting apparatus which is simple and compact in construction, of unitary form, and which may not only be economically manufactured, but

means may be employed successively upon the same manifolding assembly, and wherein the present pin type feeding unit is 50 disposed that neither the frictional feeding means nor the present pin type feeding device will interfere with norimpede the operation of the other, and will permit ready change from one feeding device to the other, whereby they may conjointly contribute to the strip feeding operation.

A further object of the invention is to provide adjustable record material guiding means by which the path of advancement of the record material may be varied either into or out of relation for engagement by the pin type feeding member.

A further object of the invention is to provide strip feeding means by which the course of the advancingstrip may be laterally varied and the device readily adapted to feeding record material of different widths.

A further object of the invention is to provide a strip feeding device having the advantageous structural. features and inherent meritorious characteristics and mode of operation herein mentioned.

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, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

In the accompanying drawings,' wherein is shown the preferred but obviously not the only forms of embodiment of the invention,

f 'The present unit Fig. 6 is atop plan view of e the mechanism shown in Fig. 5.

Fig. 7 illustrates a modification of the path of travel of the record strips past the imprinting position.

Fig.8 is a'perspective view of a modified form of the strip feeding unit.

. 9 is ayertical sectional view of the form of embodiment of the invention illustrated in Fig. 8.

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

The installation of the present pin type feeding unit upon a writing or printing machine havin conventional frictional record material feeding means enables the material to be advanced past the imprinting position, either positively with superposed plies of material in close registry and alignment with each other and with the imprint- J ingpositionjorimpositively without particular regard to registry and alignment.

There is thus provided optionally selective pin alone was utilized and it was necessary to engage the advance end of the record strip withthe pin type feedingdevice in the first instance. This is hum-- quite important when using consecutively bered record forms.

Likewise, when retracting the advanced strips as may be necessary to make corrections, the

strips-tend to buckle about the platen roll if the 'pin type-devicelocated beyond the platen roll alone is employed. Therefore, the frictional feeding means is eifectively used for such purpose:

and also to hold the record strips in adjusted re 1 lation while the advanced portions are disengaged from the pin type feeding device for purpose of making erasures. I w

Referring to the drawings, 1 is a typical tabulating machine, of which 2 is the platen roll andsuch size that the peripheral speed of the pin I and rearwardly of the platen roll 2, and the record strips 5 after passing about the platen roll and '1' the imprinting position, travel in an upwardly and rearwardly inclined path substantially tangential 3 indicates a series of frictional pressure rollers V which are manually adjustable into and out of cooperative relation with the platen roll. Such machines are motor equipped for continuous pow- .er operation. Back of the platen roll is theusual paper guide 4 over which the record material 5 is directed beneathand around the platen roll.2.f

The latter is-mountedfor bodily swinging move- Y ment into. and out of operative position, as shown m'Figs. 1 and 2. "It is to be understood that the out of engagement with the other studs, the frame may be bodily lifted from the machine.

, Mounted upon the transverse rotary shaft I is a pair of pin wheels [2, each having a complement of. radially disposed spaced pins II which are progressively engageable in marginal punched holes M in the record material 5. The pin wheels I: are axially adjustable upon the shaft 3 to vary their, relationv to accommodate record material of different widths, or to laterally change the path of travel of record material of a given width and effect alignment of prescribed areas with the imprinting position as may be desirable. The pin wheels are preferably, but not necessarily, secured in their adjusted positions by set screws II in the pin wheel hubs,,which engage in a spline or groove 16 in the shaft 9 and thereby not only lock the wheels in adjusted positions, but also maintain the pins l3 of the respective pin wheels in proper alignment. The shaft 9 and pin wheels 12 are rotated in unison with the platen 2.

' At one end. thereof inside the end plate 6, the shaft 9 carries" asprocket wheel l'l driven by a chain belt'llfroma corresponding sprocket I! mounted on the end plate 6 of the frame. The

second-sprocket I9 is connected to a gear 20 for unison rotation. The.gear20 meshes with an idler pinion 21 mounted on the frame of the imprinting machine, which in turn intermeshes with a driving gear" 22' upon the shaft of the rotary platen 2. The arrangement is such that the rotation of the platen roll-2 is transmitted to the shaft Sand pin wheels l2 thereon, which are of wheels and that of the platen roll are substantially equal, and the record material may be advanced by either at the same rate of speed.

The shaft {and pin wheels l2 are located above to the platen roll. To confine the record material to a path substantially tangential to the pin The of the wheels 12, project through the slots 24 of th plates into operative engagement in the marginal holes. in the. strips 5. The guide plates I 23 are movable laterally with the wheels l2 ,to different positions along the shaft 8. When the 7 record materialis to be advanced by the frictional feeding means independently of the pin tabulating machine I ishere shown merely for illustrative purposes, and per seforms no partof the present invention, and that the present pin type feeding unit is readily applicable "to other recording machines,'including typewriters, bill-' ing and addressing machines, and analogous mechanisms, and is not, therefore, limited in this relatively spacedend plates 6 interconlocking "engagenient with studs l l located upon the frame of the imprinting machine I. The

I arrangement is such that by oscillating the-unit I frame upwardly about one pair of studs and comprises a unitary frame their connection upon the tie rod I to a position above the path of rotation of the pins l3, whereby the record material is held out of engagement therewith. In order to confine the record material to a path of travel coincident with the guide plates 23, slotted retainer arms 25, which like the said guide plates, are mounted on the tiered l for to and from sliding adjustment and. for oscillatory motion thereabout. when in their adjusted positions, both-the guide plates and the retainer arms are secured'upon the tie rod 1 by set screws 21. when in normal operative position, the retainer arms 25,0verlie the guide plates 23 with their slots 7 26 in registry with the slots 24 of the guide plates. The pins I: of the pin wheels l2 project through the guide plate slots 24 and thence through the marginal holes I in the record misterial and into the slots 28 of the retainer Interconnecting the end plates 8 of the frame beneath the pin wheels I2 is an arcuate guard plate or pan 28 which prevents interference of the incoming record material and the bottoms of the pin wheels, and also provides a stop or rest against which the free ends of the record material guides 23 engage when in position to enable the material to be fed by the pin wheels I2. Mounted on the transverse tie rod 8 beneath the guard plate 28 are laterally adjustable fingers "secured in adjusted position by set screws 30,

by which the incoming record material is, confined to a prescribed path of travel.

The overlying strip retaining arm 25 is provided with a terminal enlargement or lug 3| engageable with the guide plate 23 beyond the mar-- gin of the record material to hold the retainer in spaced relation suflicient to permit free movement of the record material intermediate the guide plate 23 and retainer arm 25.

Instead of directing the incoming record material'over the usual paper guide 4, it may be more desirable and convenient to direct the record material supply beneath the paper guide, as shown in Fig. 7..

In Fig. 8 is illustrated a modification wherein a single continuous slotted record material guide plate 23a performs substantially all the-functions and serves approximately all purposes of the separate laterally adjustable strip guides 23. The plate 23a of Fig. 8 extends approximately the full width of the feeding unit frame and like the separate guide plates 23 is pivoted upon the transverse tie rod l 'for oscillatory adjustment,

and when in operative relation with the pin wheels the guide plate rests upon the'margin of relation with-the pin wheel, through the slot of Having thus described my invention, I claim:
