Supported between the frame members I2 in any preferred manner is the platen Il shown as being of the flat type and arranged for supporting the record strips S in smooth flat condition for the recep` tion of the impressions of the type of the typewriting machine (not shown) which is mounted upon the rails I2 for movement over the platen in a well known manner. y

Appropriate supporting means is provided for supporting the transfer or carbon sheets C in interleaved position withthe record strips S over the platen i4. Any preferred supporting means may be provided for this purpose, a carbon sheet roll i! being shown as mounted at one side of one oi' the rails i2, the sheets C being wound thereon whereby they may be unrolled to extend trans` versely of the platen I4 to the opposite side of the latter where they may be secured in any appropriate manner.

'Ihe record strips S are of the continuous traveler type and as many strips as desired may. be arranged in relatively superposed manifolding relation and led forwardly together from the supply into writing position upon the platen. These record strips may be conveniently folded along successive transverse lines into a zigzag folded supply pack such as indicated at S which is supported in any appropriate manner. Each of the record strips is provided with strip controlling apertures S2 preferably arranged in two longitudinal series along the strips. Also each strip is preferably provided with a longitudinal series of blank forms or spaces for receiving the written data and each strip may also be divided into a longitudinal series of record leaves or pad leaves S3 conveniently separated from each other by transverse lines S4 which mayfconveniently be.

weakened severance lines arranged or spaced coincidently with the fold lines of the supply pack S.

The record strips S may be restrained or held at the forward end of the machine beyond the platen Il by means of an appropriate strip securing device -indicated generally at Il, an illustrative form of which is shown in Fig. 6. As shown there is a transverse strip guiding plate i1 mounted in which are strip engaging pins Il spaced to correspond with the lateral spacing of thestrip apertures S2 so as to enter the latter when the strips are forwardly fed. These pins are preferably stationary as shown, the forward or strip engaging faces or sides being constructed or provided with an overhanging lip I9 so as to provide retaining lugs adapted to overlie the strips at the forward edges of the apertures thus avoiding accidental disengagement of the strips after the pins have been placed in position in the apertures. 'lhe top face or surface of the pins I8 may, as shown, be rearwardly and downwardly inclined in a continuously inclined surface 20 from the lip Il to the forward terminal of the pins which is preferably at or near the base. of the pin adjacent to the guiding and supporting plate i1. When the strips are fed forwardly, they will be carried upwardly over this inclined surface 20, thus moving them to disengaged position with the pin; but when they are moved rearwardly, the lip portion will enter the apertures, thus guiding the pin into aperture engaging position, holding the strips securely against rearward movement and resisting strip disengagement.

A strip restraining bar or clamp 2i cooperates in conjunction with the pins Il to retain or hold the strips against displacement at their forward endst` This clamping bar may be provided with a recess at its under side for the reception of the pins i 8 and it may be controlled or operated manually byvmeans of the mechanism diagrammatically shown in Fig. '1. supporting levers 22 pivoted at 22. to one end each of which the bar 2I is attached. The operating link 24 controlled by the pedal 25 is connected to the opposite end of the levers 22, while a tensioned spring 2| is connected to the levers to hold the clamping bar 2i normally in strip restraining position. The release of the bar will :bus be eilected by manual operation of the pedal Spaced rearwardly of the bed of the machine from the strip securing device I8 and preferably to the rearward of the platen il is a second strip restraining and controlling mechanism indicated generally at 21. This controlling mechanism may be in the form of an attachment applicable in operative position to completed billing or like machines.

'I'his Icontrolling mechanism 21 includes-a suitable supporting frame 22 adapted to be attached to the frame of the machine and arranged to support the operating parts of the mechanism. Spaced parallel guiding track rails or hars 2l are carried by the frame 2l extending longitudinally of the machine. A carriage I is supported for longitudinal reciprocationl upon the rails 29 through g'rooved rollers 2|. The carriage 20 is thus' restrained for longitudinal reciprocation adjacent to and substantially parallel to the path of the record strips. An adjustable tensioned spring 32 is connected to the carriage and anchored as at 2l, being normally tensioned to urge the carriage in a rearward direction.

Strip engaging pins Il are mounted upon the carriage 20 for longitudinal reciprocation therewith, there preferably being two such pins mounted upon a unitary supporting bar Il and spaced apart laterally the same as the spacing of the strip apertures S2. 'Ihe supporting bar 25 is provided with a rearwardly extending arm Il pivotally mounted as at l1 upon the carriage lil to the rearward of the pins Il. Thus, the pins may be swung upwardly and downwardly upon the mounting pivot I1 into and away from strip engaging position. The carriage plate 30 is preferably provided with elongated apertures 2l for the reception of the pins 2l. 'I'he path of the record strips lies immediately above the carriage l0 as clearly shown in Fig. 4, so that the aligning pins 34, when protruding upwardly tnrough the apertures 2l. will lie immediately lin the strip path in position to contact with the strips and to enter the apertures B2 thereof when the latter are brought into alignment withthe pins.

Each of the strip aperture engaging pins Il is provided at the rearwardly facing aperture engaging side thereof with a lip or extension 3l preferably as shown inclining upwardly and rearwardly from the body of the pin which is preferably cylindrical presenting a cylindrical aperture engaging surface disposed beneath the protruding lip 29. This upwardly rearwardly inclining lip is preferably quite thin or chisel-edged-at its strip engaging edge and is preferably rounded so as to present a convex engaging edge, or is similarly shaped to adapt it to readily enter strip apertures when the latter are advanced into engagement with the lip.

The forwardly facing side of each pin Il is Preferably formed to provide the rearwardly and This includes pivotedl upwardly inclined surface 4I).0 This surface preferably converges with that at the opposite side of thepin so as topresent the chisel-edged strip engaging lip 39. 'I'he surface 4U is preferably sloped off quite considerably toward the base of the pin as shown so asv to adapt it to swing out of aperture-engaging position Without injury to the aperture walls. For this purpose surface 40may be curved substantially concentric with the pivot mounting 31. rounded transversely of the pin axis so 4as to'present a surface which is convex transversely of the strip path this formation `also enabling the pin to engage or disengage smoothly with the strip apertures, and without injury to the walls of' the latter. The pins are preferably provided with threaded supporting shanks 4I whereby they are firmly attached `in correctly aligned position to supporting bar 35.

A stressed spring 42 normally urges the pin supporting bar 35 into normal position shown in Figs. 2 and 4, and the pins may be retracted by a manually operated mechanism. For this purpose, an operating lug 43 is mounted for longitudinal reciprocation in a supporting bracket 44 attached to the bar 35, said lug being yieldingly urged into extended or operative position by means of a compression spring 45. 'Ihe upper side of the lug 43 is fiat, while its underside has an inclined surface 46 adapted to engage with the operating plunger 41 mountedfor vertical movement in a supporting bracket 4,8 carried by the framework 2li.v A spring 49 is connected to the operating plunger 41 normally urging the latter into. its upper operative position as shown in Figs. 2 and 4. This operating plunger is connected-by an adjustable link with the operating pedal 25. The operating plunger is' thus positioned for engagement with the upper fiat face of the retractable lug 43 when the carriag'e3 is moved forwardly with the record strips against the tension of spring 32 tothe position shown in Fig. 4. -Forward movement of the carriage may be limited by the brackets 51vwhich thus function as stop lugs andl may be providedwith cushion bumpers. When thus positioned, depression of the plunger 41 by operation ofthe pedal 25 will swing the pins 34 downwardly about the pivotal point 31 as an axis.`

Guiding means are preferably provided vto guide-the` record strips yieldingly into engagement with'the aligning pinsthe strip guiding tensioned spiral springs 53 being very convenient anddesirablefor this purpose. These guiding springs 53 are preferably mounted in operative position Iby suspending them in tensioned condition upon a jmovablesupporting 'frame 54 pivotally mounted for swinging movement at 55 near one side of the carriage.

Although the strip guiding and supporting frame 54 does not form a part of the present invention except in combination, it may be noted that the side bars extend transversely of the record lstrip path immediately` above the latter, whereby it may be swung upwardly upon its pivotal supvpor't 55 away from operative position.. Spring their longitudinal dimensions extending substantially longitudinally of the strippath and they are positioned adjacent to the strip controlling pins 134 so as to yieldingly position the record strips This` surface `is also preferablyv in their feeding movements in position for proper cooperation with said pins.

The objectsand nature of the invention having been set forth and an illustrative embodiment described in detail, the operation of the improved device, embodied in largedegreein the above description, will now be clear and may be brieiiy summarized as follows:

Any desiredvnumber of record strips may be assembledand fed forwardly into writing position upon the platen I4 either by hand,l or if desired, by an appropriate feeding mechanism. Prior to this feeding movement', the record strip controlling device including the pins 34 will'occupy the position shown in Fig. 2, the controlling carriage 30 then being in its rearward retracted position in which it is yieldingly held bythe spring 32.

As'the record strips are thus fed forwardly, l

they 'are yieldingly urged by the pliable guide springs 53 into cooperative relation with' the controlling pins 34. Thus, the pins occupy an advantageous position for seeking out and'entering the controlling apertures S2.

If the strips are slightly out of alignment with each other either transversely or longitudinally thereof, the novel pin structure described including the lip portion 39 is especially well adapted to .seek and enter the apertures even though said apertures maybe obstructed by thetransverse or longitudinal disalignment of the strips. Even when the apertures are nearly or fully closed by such disalignment, these pins are very efficient inv finding their way into all of the apertures, thus aiding greatly in bringing the strips into correctly aligned superposed vrelation with each other.

Continued advancement of the strips after the pins have entered the apertures will cause the controlling carriage 30 to move forwardly against the tension of spring 32 until'the forward strip apertures are brought a short distance in advance of the forward pins I8 before being checked by ,the brackets 51. 'The strips are then allowed to retract'rearwardly slightly by virtue of the tensioned spring 32, causing the hooked ends of the pins to be entered in the strip apertures and bringing said apertures against the forward lipped side ofthe forward pins I8. The record `strips are aligned, tensioned, and smoothed in` correct writing position over the platen I 4, whereupon the inscription may beinade.

When the record strips are fed forwardly as just described,A it will be understood that the pedal 25 is depressed, thus raising the front strip retaining bar I6 to release the forward ends of the strips, and at the same time depressing the operating plunger 41. Therefore, when the carriage 30 movesl forwardly with the advancing strips, the operating lug 43 for the pins :I4`

will be positioned to directly overlie the operating plunger 41. Upon release of the pedal, the

plunger 41 is moved upwardly by spring 49 engaging the inclined surface'46 to cause retrac` tion of the lug 43 until the plunger 41 occupies the operative overlying position as shown in Fig.

4. The parts occupy this position during the writing operation. After completion of the writing, the next operative cycle may be initiated. That is, the inscribed parts of the record strips are fed forwardly as above described, 'whereupon they may be torn off across the forward edge of the bar l5, or they may be severed in any other preferred manner. As the pedal 25 is depressed preceding this strip feeding action,v descent of the plunger 41 carries the pin supporting bar 35 downwardly about the pivotal support 31 thereof. This pivotal movement causes the controlling pins 34 to descend with a pivotal or rotary motion about the point 3l so as to carry the aperture engaging side of the pins slightly forwardly longitudinally whereby the pins are caused to disengage the apertures with an aperture freeing action. By virtue of this action the lipped strip engaging portions I9 of the pins are carried forwardly to a sufficient extent to free the walls of the apertures, thus avoiding obstruction to pin withdrawal, or tearing or otherwise marring the aperture walls. Also, during this aperture disengaging movement of the controlling pins, the convexed or curved surfaces 4l of the pins are effectual in avoiding any obstruction or injurious engagement of this side of the pins with the opposite or forward walls of the strip apertures. Therefore, by virtue of this arrangement, the pins mayreadily be withdrawn vfrom aperture engagement without any obstruction whatsoever and without any tearing or marring of the strips. At the same time the lipped construction 39 of the controlling pins not only greatly aids entry of the pins into aligning and controlling position in the apertures, as above described, but it also aids very materially in retaining the strips in controlling engagement with the pins, largely because of the strip overlying lips or extensions When the pins are fully withdrawn from the aperture as shown in Fig. 5, the carriage is freed from the strips S and is returned by the spring nto its initial position, as shown in Fig. 2.

In order further to facilitate the withdrawal of the controlling pins Il from engagement with the strip apertures, the lugs $2 are placed upon the plunger 41 in position to engage with the' v bifurcated bracket Il when said plunger is being elevated upon pedal release and the controlling carriage 30 is in its forwardly moved position as shown in Fig. 4. As the plunger 41 is thus raised by action of the spring 40, the pins or lugs l2, as they engage with the convexly curved surfaces of the bracket il, will impart a slight forward movement to the carriage Il, thus moving the pins Il slightly away from engagement with the adjacent rear walls of the strip apertures S2.

However, lust prior to this forward movement of the controlling carriage, the strip gripping clamps Il' positioned to the rearward of the writing area of the platen I4 will have been set so as to clamp the strips in smoothed writing position on the platen while said strips are still under the smoothing and tensioning influence of the controlling carriage. It will be understood that the strip clamping device Il' may be similar to those commonly used in machines of this type and therefore are herein disclosed diagrammatically merely. As shown thus diagrammatically in Fig. 7, the clamping device Il is released from strip clamping position when the pedal is depressed as for example by depressing the rearward edge or end of the platen I4 slightly by means of the operating connection 2l between the operating link 2l and the platen. The

rstrip supporting surfacev of the platen is thus moved slightly away from clamping members I4" l which may be stationary, thus releasing the grip at theopposite edges of the strips. K

Thus, when the controlling carriage I0 is forwardly moved as just described by actuation of the plunger l1, the strips have already become clamped at their forward end by the clamp 2| and at the rear end of the platen by the clamping devices Il'. The forward movement of the carriage therefore moves the pins 34 away from the strip aperture walls as described. Being thus freed from engagement with the aperture walls the pins 34 may move freely to disengaging position as the plunger I1 descends thus further insuring that no tearing or other damage to the strip apertures will be caused when the pins are withdrawn. Also, it will be observed that the rearward movement of the carriage after withdrawal of the pins I4 from strip engaging posi tion cannot be initiated until the lugs l! have passed downwardly beyond the end of the bracket BI. This prevents any premature movement of the carriage which might result in damage to the strips or to the walls of the strip apertures.

Since certain changes may be made in the above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that al1 matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
