This invent-ion'relates to improvements in apparatusv for, making manifold; records and,

with respect toits more "specificfeatures, to.

the feeding and directing ofrthe record strips 8 in autogra'phic registers in which the record strips are simultaneously advanced from. a

supply ainto relative superposed position for inscription.

' One of the 'objects of the inventionis'the 10 provision of an apparatus of the character referred to wherewith the folding of a strlp in the chamber may be accomplished without the necessity of preliminarily modifying the strip for engagement with the folding device.

Another ob'ect is the provision of a practical device a apted positively to engage the strip at whatever point the strip may be presented thereto and fold and otherwise direct the strip in a predetermined manner without impairing the strip and without defacing the record on the strip. j

Another object is to provide, a simple and practical device for accomplishing the above objects while maintainingthe form reg1stering devices in efficient'operative'condlt on.

A further object is to provide means ada ted to be associated with the feeding means or engaging with certain selected record sheets to present those record strips preferably n a record compartmentgin a manner 1 d1fl"e'rent from other record strips, and in its more specific application when used, with record sheets attached together to form a continuous strip to present alternate record strips 1n reverse due direction to fold-the strip zigzag.

Other objects will appear in part obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of ele ments, and arrangement of parts, which will be exemplified in the constructions hereinafter set forth and the scope of the application of'which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a longitudinah section of a machine embodying this invention having the covers raised and a paper record strip indicated in dotted line;

Fig. 2. is a fragmental vertical cross-section along the line 22 of Fig. 1 showing the de-' tails of the feeding and selecting mechanism;

Fig. V3 is an enlarged detail of the feeding andselecting mechanism while the strip grip ping mechanism is engaging the strip; and

F g. 4 1s a View similar to Fig. 3 at a time when the gripping mechanism does not grip the strip.

It has heretofore been proposed to construct autographic registers for use with strips of record leaves, one of which is carried into a receiving chamber in which it is desired to fold it zigzag to form .a fiat package for record purposes. With such machines, however, difliculty has been experienced in lnsuring that the sheet fed into the compartment will fold flat.

It has furtherbeen proposed so to position the location of the refolded pad that the sheets normally. tend to enter the record compartment in the direction of one of the folds and to provide mechanism for definitely engaging the alternate record sheets to reverse their direction for insuring the location of each other fold.

In accordance with that construction, certam of the record sheets are modified and the mechanism is arranged so that it will respond only to the modified sheets. In accordance with the present invention, it has been found possible to utilize a strip engaging mechanism which is adapted to grip the strip at any (point with which it may come into contact an to secure the proper selecting action by timing the operation of the gripping means relative to feed.

A desirable type of machine with which this improvement maybe used comprises one in which the supply pad is in the form of a plurality of strips interfolded zigzag and provided with feed control apertures; while the feeding means is responsive to the apertures to control the length of strip fed by engagement with an aperture. This invention is accordingly illustrated as applied to a machine ofthat type commonly called the disc feed t pe.

Re erring now more specifically to the drawing:

The numeral 1 designates a'casing divided in general into two compartments 2 and 3, as by a partition 4. The compartment 2 is adapted to receive a supply pad of record strips or webs interfolded zigzag to form superposed sets of superposed record leaves while the-other compartment 3 is intende the operation of the to receive one of the strips as a permanent record refolded in zigzag manner. Interposed between the compartments 2 and 3 is a feeding means designated generally by the numeral 5. Suitable means are provided as shown at 6 for separating the strips and guiding them over a tablet 7 pivoted as at 8 above the compartment 2, and a margin frame 9 is pivotally supported at one side as id of the casing to cover the tablet. The casing may be provided with the usual receptacle at the side of the tablet for the reception of a roll of transfer material which receptacle may be adapted to be closed by the extension 11 at the side of the margin frame 9.

A cover or top 12 may be provided for the compartment 3 which cover may extend to a point adjacent to the feeding means and be adapted to separate the lowermost strip which is to be diverted into the compartment 3 from those strips which are to be delivered from the machine. The feeding mechanism comprises in general a pair of discs 15 mounted upon a shaft 16 journaled at 17 in the sides of the casing. There is a handle 18- i upon the shaft 16 for the purpose of turning the shaft while a spring stop 19 mounted on the side of the casing is in position to stop the handle 18 at the completion of a revolution.

(lo-operating with the discs 15 is a roller 20 which is shown in rear of thetop 12 and pivoted in blocks 21 sliding in grooves 22 in the cross bar 23. A spring 24 within the groove urges the blocks 21 downwardly while a pin 25 limits the downward movement. The cross-bar 23 is pivoted on one side as at 26 and held by a spring catch 27 upon the other side. The stop 25 is so adjusted that the springs 24 will, during the normal operation of the machine. urge the roll 20 toward the discs 15 to grip the paper strips between them and cooperating pinion and gear 28 and 29 are adapted to drive the roller 20 with the same peripheral speed as the discs 15.

The machine illustrated is adapted for use with strips of record sheets having lines of control apertures in definite relationto the sheets and'the discs 15 are in longitudinal alignment with the control apertures. W1th such a construction, the discs and theroller' 20 will grip the strips to feed them forward until the control apertures come oppsite the discs whereupon the feed will stop. The relation of the control apertures and the record sheets is such that the record sheets will be in registry with the writing tabletat the completion of the feed. Auxiliary lugs 30 are provided to grip the strips beside the apertures to commence the feeding movement.

The compartment 3 is so positioned relative to the feeding mechanism that a sheet fed beneath the cover 12 will normally extend and be directed toward the far end 31 near its periphery as at 34 an arm 35 carrying at one end a pin 36 and. at the other a cam surface 37'. The arm 35 is mounted upon the stud 34 for oscillatory movement through an are sufficient to cause-the pin 36 to project beyond the periphery of the disc 33 and'to be retracted completely below the disc surface, and a spring 38 is arrangcd'to'project the pin unless the arm be otherwise restrained.

A guide-38 is provided upon theunderface of the cover Hand-this guide has a cen tral slot through which, the pin 36 may project. Thus the guide 38 furnishes a support for the strip so that when the pin 36 is projected, the strip will be held in place for the pin to pierce it. 7

Also mounted'upon the disc 33 is a rotary cam 39 having one or more cam faces 40 in position to engage'the cam surface or trigger 37. This cam 39 is mo'untedfor rotation about a pin 41 and carries with it a star wheel 42. An arm or tooth'43 is supported by the casing in positionto engage the star wheel 42 and move it one notch for each revolution of the disc 33 and a spring 44 bearing upon the surface of'the disc is adapted to hold the star wheel in any position to which it may have been moved.

The mating cam surfaces 37- and 40 are so positioned relative to the star wheel that as the star wheel is moved step by step by the arm 43, the pin 36 is positively retracted by a the cam below'the surface of the disc on one revolution, and released to be projected upon the next revolution, alternating with each revolution.

In accordance with the construction out.- lined,it will be clear that the pin 36 will be released for projection when the arm 43 encounters the star wheel. In order, therefore, to delay projection of the pin until the position illustrated in Fig. 3 has been reached, a cam 45 is provided having a substantially concentric cam surface 46 and a pin 47 upon the arm 35 projects into the pathway of the cam surface 46 and the relation of these parts is such that so long as the pin 47 is in engagement. with the cam surface 46, the pin 36 is held retracted, but'as soon as the pin has passed over the heel 48 of the cam 46 substantially in. the position as shown in Fig. 3, the spring 38 may project the pin, provided it is not restrained by the cam 40. The relalows: i

ment, the cam 40 having been turn in registrywith and project through the beginning of the coming record sheet rather than the end of the previous one.

- If the strip used with the machine is biased 5 so as to refold more readily in the same direction that it was previously folded, it may be preferable under some circumstances so fold linewill fold substantially as easily in one direction as in the other. Such a strip may be used with a machine without being timed relative to the projection of the pins.

The operation of the machine is as fol- The web supply is placed in a compartment 2 and the strips are carried past the separators 6 over the tablet 7 to the feed mechanism, with the transfer sheets interleaved between them. The strip supply, if it have control apertures in it, may have the control apertures'brought into registry with pro-aligning pins 50 upon the'feed disc and the lowermost web may be carried below the guide 38 and the upper webs above the cover 12; Thereupon the cross-bar 23 may be put in place and the margin frame 9 closed. The machine-is now ready for inscription.

After inscription, to bring a new record sheet into position, the catch 19 may be depressed with the thumb and the handle 18 turned, whereupon the lugs 30 engaging the strips, feed the strips forward until the ap'- ertures are past the discs 15 whereupon the feeding is continued by the discs 15 until'the next successive control aperture is reached whereupon it ceases because of the failure of the discs to engage the strips.

Assuming that the star wheel and cam are in the position shown in Fig. 3 just after the beginning of the feeding -movement, the pin 36 will be projected through the forward end of the record sheet as soon as 0 the pin 47 haspassed over the heel 48015 the cam 46, and this pin will grip the forward end I of the sheet at a point beyond where it first separates from the other strips and carry it.

downwardly substantially to its position at tion bowed outwardly around the fee ing mechanism. As the feed continues the strip I bows more and more.

, Upon the next succeeding feedm moveas def th tion o fo1d-,---that is, so that the the end 32 of the record pad. Thereupon the forward end in position and its rearward orscribed-to the point of positively retracting the pin, it is heldretracted by the cam 40 during the beginning of the next revolution I v and hence,- when the next succeeding sheet is fed,'its forwardend will not be gripped by the pin. Thus the bowed portion of the sheet will continue-to enlarge until the next fold line; is definitely in place at-the far end 31 of the record pad, V 1 Thus it will be seen that the one fold line is put in place atthe far end of the pad by the direction of feed of the machine, while the next fold line is'drawninto place by the- "pin 36, and thus the sheet is refolded in zigzag form in the supply pad, the pin 36 engaging behind each alternate fold line.
