19 Claims. 01. 282- 12 This invention relates to manifolding, and isa division of my copending application Serial No. 335,402, flled January 28, 1929, which matured into Patent Number 1,957,405, May 1, 1934, and.

forms part of the invention described and claim-- ed therein. The present application concerns the manifolding pile or pack per se.

In the art of manifolding, it is frequently desired to simultaneously feed work sheets and carbon sheets which are of indefinite length, so that the writing process might be continuous. In such work, to keep the several superposed strips in register longitudinally and transversely, it has been proposed to provide the strips with marginal rows of holes and to provide on the writing machine wheels having pins for engaging in these marginal holes to feed the sheets. To provide these marginal rows of holes in the carbon strips requires that they be passed through a printing press or similar machine equipped with punching devices. This processing of the carbon strips increases their cost and hence the cost of the supplies needed for performing the work. Yet, it is necessary to keep the carbon strips -in substantial register with the work sheet strips, for otherwise they may gradually work outwardly of the pile in the feeding operations, or be actually jogged outwardly during the return movement of the carriage when used in a' typewriter. so A feature of a portion of this invention claimed herein is the provision of a manifolding pile having the work sheet strips provided with margins extending beyond the side edges of the carbon sheet strips so that the carbon sheet strips need 5 not be engaged by the pin-wheel feeding device and so that the margins may constitute feeding bands between which no carbon or transfer material is interposed, permitting feeding or other pressure to be'applied to said side margins of the 40 work sheets without smudging of the undercopies as a result of such pressure.

Another feature is the provision of the relatively narrow carbon strips of such width that their side edges are tangential to the pin-wheel' 5 feeding apertures in the work sheet strips whereby the pins' engaging through said apertures may act as gages for the carbon strips and bring the carbon strips into desired lateral position with relation to the work sheet strips should they tend w to slip sidewise.

Other features and advantages willhereinafter appear. In the accompanying drawings, which show one form of the invention, that at present pre- Figure 1 is a sectional side view of part of a carriage of a typewriting machine, showing the device of the present invention applied thereto, and also showing a pack of stationery for use with the machine. 5

The manifolding pile of the present invention 20 may be used with various machines and, to exemplify the invention, is illustrated herein in the same connection in which it is illustrated in my said copending application, Serial No. 335,402, filed January 28, 1929, of which this is a division, 25. wherein there is shown'a typewriting machine having a. platen 10 for supporting work sheet strips ll and carbbn sheet strips I2 in position to be engaged by type bars l3 which, as indicated, swing upwardly and rearwardly against the front face of the platen to imprint characters on the uppermost work sheet strip l I by means of a rib-'- bon I4 and to cause those characters to be duplicated on the under strips H by the carbon sheet strips 12, one of which is provided for each of the under work sheet strips H. The platen I0 is mounted in a carriage I5 adapted to travel to and fro in letter-space direction. In the form shown,

the carriage slides on a square shaft l6 passing through the center of the platen l0 and serving to rotate the platen when it is rotated and has a rear guide I! upon which it rides.

The carriage I5 has a paper table 15a at the introductory side of the platen for guiding work 45 sheets thereto and the forward part of the table has an apron 15b which holds the work to the platen.

The work sheet strips ll usually contain a succession of printed forms having delineated 50 spaces IS in which indicia is to be written. Due to the proximity and restrcted area of the spaces l8, it is imperative that all the work sheet strips I I be maintained in accurate registration, so that indicia written in the delineated space of 'one 55.

strip will be located entirely within the corresponding delineated space of the other strips.

To maintain this desired registration, it has previously been proposed that, as shown in the accompanying drawings, the work sheet strips ll be provided with holes l9, arranged in succession forming rows extending longitudinally of the strips and at the side margin 2|] thereof. The holes H are adapted to be engaged by pins 2| carried by wheels 22 secured to the platen ||J so as to rotate therewith. In the feeding operation, the pins 2| being engaged with some of the holes l9 advance the strips coincidently with the rotation of the platen, and as the pins one after another engage succeeding holes at the introductory side of the platen, due to their tapered ends 23, they bring the strips into ac- .curate registration and positively advance all of the strips together without any danger of slippage between them. The paper apron |5b holds the work sheets close to the platen and the pin-wheel so that the pins will extend through the holes IS. The paper apron |5b is slotted at |5c to permit rotation of the pinwheels without interference of the apron with the pins.

Were the carbon sheet strips |2 similarly provided with holes, they too would be held in the desired relation to the work sheet strips I. But, to thus prepare the carbon sheet strips it would be required that they be passed through a machine which' would punch the holes in the side margins and this would add cost to the pack or roll of stationery.

To avoid this, the present invention provides means for guiding and controlling the positions of the carbon sheet strips so that they are maintained in the desired location between the work sheet strips without requiring that they be procarbon sheet strips by their side edges both at the platen and at a point at the introductory side of and close to the platen.

The means for accomplishing the last-named function in the form shown herein, comprises a frame24 having side plates 25 between which are secured guide rods 26 over which both the work sheet strips H and the carbon sheet strips |2 ride, one strip engaging each rod. The frame 24 is pivotally mounted in arms 21 forming part of the carriage I5, and this is done by extending one of the rods 26 from the side plates 25 to the arms 21 of the carriage. This mounting 0d the frame permits the latter to swing and assume the most natural position for guiding the strips. In loading the machine, the strips H and I2 are led from a pack P supported on a table or other convenient device and the strips are separated with one strip only passing over each rod 26.

In the .form shown, the work sheet strips are guided by directly engaging with their side edges 20 on'inside surfaces of the plates 25, and thus are kept in accurate alignment; with each other. The carbon sheet strips l2, however, which, for reasons stated below, are narrower than the work sheet strips, engage with their side edges |2a against guiding blocks 28 placed between the rods 26 which lie above and below "the, carbon strip l2. The guides 28 are each rod.

As stated, and as is customery, the work sheets are guided and held in accurate alignment at the platen by the engagement of the pins 2| on 'the pin-wheels 22 with the marginal holes l9 in the work sheet strips. To guide the carbon sheets and prevent them from shifting transversely at the platen, the present invention makes the carbon sheet strips 2 of such width or places the pins 2| in such position (according to which change is most convenient or desirable) that the side edges |2a of the carbon sheet strips i2 are in position to be engaged by the inside edges 2|a of the pins 2|, as shown in Fig. 3. The pins 2| thus hold the carbon sheets l2 captive between the work sheets at the platen and should a carbon sheet tend to skew or to creep sidewise during the rotation of the platen, the-pins 2| will cam or guide them back into position.

Of course, it is not absolutely essential that the distances between the side edges |2a of the carbon strip and between the inner edges 2 |a of the pins be absolutely the same, but when used with the mechanism described it is preferable that they be substantially the same, leaving only such clearance between the edges |2a of the carbon strip and the edges Zia of the pins as is necessary or expedient to compensate for variations in the manufacture of the parts and paper. The space, however, between the side edge |2a of the carbon strip and the inner edge 2|a of the pin must not be so great as to permit substantial movement of the carbon sheet, for otherwise should the sheets'skew for some reason between the guides 28 and the point where the pins 2| engage the work sheet strips, the carbon strip might overlie the apertures i! in the work sheet strips and be pierced by the pins. The danger of this occurring is mitigated to a great extent by the provision of the guide blocks 28 for the carbon sheets at the introductory side of the platen and taken together with the side edges of the pins 2| have been found in practice to keep the carbon sheet strip well confined and against lateral movement relatively to the work sheetstrips.

After the strips I have been fed around the platen by the pin-wheels 22,'they are stripped from the pins by a plate 3| at the delivery side of the platen. The plate 3| has slots 32 through which the pins passto lift the paper from the pins as the platen is rotated, the paper being forced to travel upwardly along the plate.

The carbon and work sheet strip controlling means of the present invention is extremely advantageous, particularly in connection with automatic or telegraph typewriters which frequently operate for relatively long periods without being observed by an .operator.

The frame 24, instead of being arranged so that the side edges 20 of the work sheet strips engage the plates 25, as shown in Fig. 6, has other blocks 28;: for guiding the work sheet strips and these may be adjustable as in the case of the blocks 28. v

From the above, it will be seen that the proper relationship between the pins 2| and the side edges |2a of the carbon sheet strips may be obtained by either changing the positions of the pins or making the carbon sheet strips wider, that is, changing the machine or the pack of stationery. Accordingly, the present invention be jointly divided into a plurality of multiplicate contemplates and embraces not only the mechanism disclosed and claimed in my copending application aforesaid, but also a. mani'folding pile claimed per se herein.
