This invention `relates to billing or si-milar machines and more particularly in some of its details,`it relates to improvements in mechanisms forl adjusting and aligning the paper record. strips used in such machines so as to bring said strips in correct position for the reception of an inscription, and furthermore to tension the strips for similar purposes.

4It is the 'general object of the invention to A m provide an improved practical mechanism for positioning and aligning one or a plurality of superposed record strips orV sheets to bring.

y 2.5 ing member in its aperture entering movement.

A further object is to provide, in a'machine of the class mentioned', 'an improved strip aligning mechanism` to positively align and position the strip or strips in inscription re-y ceiving position and'to positively tension said strips and clamp -them in aligning position. A further object is to provide, in a machine of the class mentioned, an improved manually operable oscillatable strip engaging member, engageable-With the strip or strips to positivelyadjust them into aligned position.

Another object is to provide, for machines of the class mentioned, an improved aligning mechanism adapted4 to engage one or a plurality of superposed record strips at parts spaced longitudinally thereof and to 'provide an improved operating mechanism to manually move one of the engaging mechanisms longitudinally with reference to the other, so as to positively move the strips into correct position,

Still another object is to provide an improved mechanismy of the `class mentioned which is simple inconstruction, positive and effective in operatiom and capable of simple and quick installation on billing or like recordingfmachines of existing construction.

Other objects Will be in" part pointed out in the following detailed description of an illustrative butppreferred embodiment of the invention, and Will be in part obvious in connection therewith.

The invention accordi-ngly'comprises the features of. construction, combinations of. elements, and arrangement of parts, which Will be exemplified in the construction hereinafter set forth and the scope of the application of which Wil-l be indicated in the claims.

For a more complete disclosure of the nature and objects of the invention, reference is had to the following detailed description, and to the accompanying dravvings in which:

Fig. 7 is a fragmentary plan of one of the record strips. l

The improved aligning and tensioning mechanism'may be embodiedv in 'Writing or like machines of different character but it is particularly adapted for application to billing machines and may be applied as an attachment to billing machines of existing construction. Y

Referring ,to the drawings for a'detailed description of the embodiment of the invention there shown, it will be observed that the improved aligning mechanism is applied to a billing machine of the flat platen type over which the Writing machine proper travels f tion,

, strips into a series of form leaves.

upon supporting rails in order to effect line spacing.

-The supporting frame for the machine may beof any preferred form, the showing Aof the drawing being somewhat diagrammatic and fragmentary for convenience of illustra- The main supporting framework or base 10 carrying the operative mechanisms of the machine may be supported in any desired manner as by a pedestal or other form of support (not shown). The framework 11 for supporting the track and the record sheets to be written upon may be supported upon the base 10, and includes two parallel longitudinal side rails or bars 12 connected byl transverse frame members or cross bars 13. The typewriting machine employed for writing upon the record strips is diagrammatically shown in dot and dash outline at 14 and is mounted upon the longitudinal side rails for movement back and forth thereon over a flat writing platen 15 which supports the record sheets or strips S in flat smooth position for receiving the impact of the type. As will be understood by those familar with this art, the general arrangement of the record strips and typewriting machine is such as topermit the type to strike upon differentpartsof the record strips S to impart printed impressions thereto, whereby blank bill forms or like forms upon the strips may be filled in with appropriate dat-a. As it is usually desired to make more than one copy, a plurality of superposed record strips may be employed as shown in the drawing, carbon sheets or similar transfer material being interposed between the adjacent superposed -sheets over the platen. If carbon paper isused to transfer the records, the supplyl thereof may l supported adjacent the platen in any preferred known manner. As many record strips S may be superposed, one on another as desired to provide the required number of copies. j

The supply of blank record strips is preferably arranged in the form of a zigzag supply pack or pad S which maybe supported and housed upon or adjacent to the machine in any convenient manner. Each of the record strips may be provided with apertures S2 therein` which are preferably arranged in two longitudinal series on each strip providing pairs of apertures disposed upon transverse lines of t-he strips as shown in lthe drawing. These apertures 'are utilized for cooperation with strip aligning and tensioning mechanism'described below, the pairs of transversely disposed apertures respectively bearing a detlnite relation to blank forms which may be printed in a longitudinal series upon each of the strips. Also it is desirable that adjacent blank forms on each of the strips be separated by transverse perforated or `similarly weakened lines, thus dividing each of the These weakened transverse lines aid in severance of the form leaves from the strips-after a record has 'been entered thereon.

In order to retain the record strips in correct position on the platen for reception of an entry or -inscript-ion thereon, and to assist in effecting alignment of the strips with reference to each other and to the writing platen, a clamp or similar holding means is provided in the vicinity of the platen. This strip retaining means may be of different preferred forms, that shown being in the form of transverse clamping bar 16 positioned to rest against a cross plate 17 mounted in forwardly inclined position at the front of the machine upon one of the cross frame members '13. This cross plate is removably clamped in position by means of clamps 18 engaging lugs 19 upon the cross plate and appropriate lugs on the frame of the machine as shown. The cross plate 17 is provided with a pair of upstanding pins vor posts 2O preferably flattenedor elliptical in cross-section and positioned to enter the apertures formed in the record strips S, and apertures 21 ofthe clamping bar 16. The major aXes of the pins 2O are aligned transversely of the frame, and the longitudinally disposed minor axes are considerably shorter than the diameters of the apertures 21, permitting longitudinal adjustment of the cross-plate 17 relatively to the clamping bar 16. Also the minor axes of the elliptical pins 2O are considerably shorter than the diameter of the strip apertures so as yto permit longitudinal adjustment of the strips when impaled by the aligning pins 20. In the illustrative embodiment disclosed, the pins 2O are rigid and stationary with reference to the cross bar 17 and with reference to the frame of the machine. The clamping bar 16 serves as a severing edgey at the forward part thereof for tearing ot'the form sheets fromA the supply strips, and the pin supporting cross plate 17 underlying the clamping bar is cut away at its forward edge to provide a recess tofacilitate grasping of the forward edges of the strip.

,-Movement of the clamping bar 16 to and ayifay from the-cross plate 17 to grip and release the underlying record strips may be provided for as shown in the drawing by means of a system' of levers controlled by a rod or link 23 connected to a manual operating member, as a pedal 24 pivoted to aA supporting standard or column 25 depending from and mounted upon the base plate 10. As shown the clamping bar 16 'at its opposite ends is connected to and supported by levers 26 pivoted to the side rails 12 by means of a transverse rod 27 extending through the levers and attached at its opposite ends to the side rails. Each of the levers 26 is furthermore articulated to the adjacent side rail by means of a link 28 loosely pivoted to the lever- 26 at 29, and pivoted to the adjacent side rail at.3(). l The rock arms or levers 26 are biased to hold the clamping bar in gripping position by means of one or a lurality of tensioning springs 31 anchored) to the frame and to the lugs 32 depending from the rock arms. A U-shaped operating vlever or yoke 33 is pivoted through-its opposite legs tothe adjacent links 28 by meansof a pivotal rod 34, the leg of the yoke extending beyond this pivotal rod to underlie and contact with the rod 27 which thus acts as an abutment or fulcrum for the lugs of the U-lever when it is rocked by the pedal to operate the clamping rod. The pedalrod 23 may be connected by means of a hook at its upper end tothe U-lever 33. By means of this mounting lfor the clamping bar 26 and ythe operating connections therefor, it `will be seen that depression of the pedal will raise the clamping bar to release its grip upon the strips, while the bar is returned to 1 gripping position by operation of the springs 3l when pressure upon the pedal is released.

Positioned rearwardly of the platen is another strip engaging mechanism which is active inA positioning and aligning the strips. This mechanism includes a rock shaft 35 extending transversely of the frame of the ma- -chine and connected to be rotated in strip aligning direction by raising of the pedal. These operating connections include a crank arm 36 secured to the rock shaft 35 andconnected by a link 37 with one arm of a bellcrank lever 38 pivotedto a bracket 39 which may be d etachably attached to one of the cross frame members 13. The opposite arm ofthebell-crank lever 38 is positioned to lie in a notch or aperture 40 formed. in a link positioned at each side of the crank pin head so as to anchor the connecting link securely to the crank pin. At its opposite end the operating link 37 is securely connected to a crank pin 45 on the bell-crank lever 38, being similar to crank pin 42 and the link being secured against longitudinal sliding movement through the crank pin by nuts 4 6 threaded yon the link and positioned at both sides of the crank pin. y

The rock shaft 35 is preferably mounted at its opposite ends in supporting plates or brackets 47 spaced apart so as to lie with their.

outer faces against the inner faces of the side bars l2. These supporting brackets are arranged to be clamped and supported in position on the machine frame by clamps 48 preferablyfattached to the brackets and lspanning the lower edges of the side rails and secured to said side rails by set screws or similar securing means. Secured also to the supportl ing brackets 47 and extending transversely of the machine frame are structural tie bars 49 and 50 which may also function as strip guiding and supporting rods, and an additional strip guiding and supporting rod 51 having edge guiding flanges 52 thereon for positioning the strips edgewiseas they pass onto the bed of the machine from the supply pad. A unitary guiding and aligning member is vt-hus provided by the bracket plates 47 and parts supported thereby which may readily be placed upon orremoved from the, billing machine. 1t will thus be seen that the entire strip aligning and tensioning attachment togetherwith operating connections therefor may readily' be applied to billing or like machines of existing construction with aminimum oflabor and effort and without alteration or impairment to the machine construction and without interruption tothe normal operative functions of the machine.

Rigid arms'53 are rigidly mounted upon the rock shaft 35for rocking motion therewith,

`said arms extending above the shaft and beingspacedfapart a distance approximately equal to the transverse spacing of the strip aligning apertures. These rock arms togetherl with therock shaft constitute a rockable ca-rrier for a pair of rigid strip engaging, strip aligning members or pins 54, each mounted on one of the arms 53 for projection into strip aperture 'engaging position and for retraction. In theembodiment shown, each of the projectable aligningpins pivoted to one of the carrier arms to effect the projection and retraction of the strip engaging part thereof, and is provided with a strip aperture engaging part or projection 55 which is preferably oblong in cross-section with the minor axis extending longitudinally of the machine frame, the forward strip engaging face thereof being rounded or cylindrical for 'contacting with the curved walls of the strip aligning apertures. Each aligning pin 54 is provided with a laterally projecting cam or lug 56 from which depends a stop lug 57 positioned for engagement with the rock arm to limit pivotal movement of the aligning pin in one direction. The rock arms are provided at their swinging ends with recesses for receiving the pivoted aligning pins and a spring pressed friction plug 58 is mounted upon the rock arm preferably at the bottom ofsaid recess and positioned so that the outer end thereof is spring pressed into frictional contact with the lower cylindrical face of the aligning pin. This friction plug thus acts as a friction brake to restrain the pin in any position to which it may have been moved.

Positioned above'the rockable ca-rrier is a transverse tie rod 59 connected at opposite ends to the bracket plates 47 and providing a support for trips or trip lugs 60 which are positioned for contact with the pin operating' l lug 56, when the aligning pins are carried bodily by the carrier, so as to effect pivotal or rocking movement of the aligning pins. The outer ends of the trip lugs are also 'positioned for contacting with the adjacent faces of the pin projections 55 to rock the aligning pins inthe opposite direction when the latter are moved by the carrier when swinging in theopposite direction. Rocking pressed to raise the clamping bar 16 and to move the aligning pins forwardly into strip disengaging position, thestrip may then be threaded over thegpide bar 5l into writing position over the platen, the forward ends of the strip being inserted under the clamping -bar with the adjacent strip aligning apertures threaded overrthe stationary aligning pins 20. Pressureiupon the pedal is then released whereupon the operating elements are positively returned to normal position under the influence of the spring 3l which is relatively heavy and of suficient' strength' to positively force all the connecting operative elements into final position.

As the pedal is returned to normal position, the aligning pin Acarrier Ais positivelyv rocked in a clockwise direction as viewed in Fig. 2, imparting movement of translation to iso the aligning pins 54, and as this movement continues the lugs or cams 56 Contact with the trips 60 effecting rotary movement of the pins in a direction counter to the -rotation of the carrier. A composite movement, that is movement of rotation and movement of translation, is thus imparted tothe strip aligning pins, and thestrip engaging projection 55 gradually swings into upright position, the end thereof wiping or' sliding over the under face as the movement continues.`

Because of the composite movement of the aligning pins, entry of strip engaging projections into the apertures is facilitated,` and to furtherfacilitate this entry into the apertures, the operating connections are preferably positioned and proportioned so that the strip engaging ends of the pin projections are givenpa slight movement forwardly of the strip as they Contact therewith, and are thfn moved rearwardly thereof. The effect of this action is oscillatory movement of the strip engaging end of the pin projection longitudinall'y of the strip while in contact with the latter, the pin projection thus functioning as asojrt of a feeler to find its way into the strip apertures. This feature is of special advantage and utility where a plurality of superposed strips are employed and the corresponding aligning apertures therein chance to be out of exact registry with each other. Due to this oscillatory action, the pin projection is enabled to thread its way into the apertures of the superposed strips. lien the projections 55 reach substantially upright position, they are stopped there by contact of the stop lugs 57 with the adjacent faces (jf. the rock arms.A This stopping action occuns some time before the carrier reaches the rearward limit of its swinging movement so that, for the remainder of the movement of said carrier, the aligning pins move as a rigid'unit therewith, the rounded or cylindrical surface of the pin projection being in engagement with the rearward walls of the aligning apertures so as to positively force the strips rearwardly into correct aligning position, and to tension and smooth them over the writing platen.

During the aligning action of the aligning pins 54 as described above, itvwill be understood that the strips areimpaled at their forward extremities Vover the stationary strip aligning pins 20, but the strip aligning apertures being of greater diameter than the minor axes of the stationary aligning pins, relative longitudinal movement ofthe strips is permitted, while at the same timethe for* ward ends of the strips are restrained within certain' limits. j

Also theoper-ating connections are so proportioned and adjusted that the clamping bar 16 is set to grip the strips only after aligning action of the pins 54 is substantially coinpleted, alignment of the strips being at that time completely effected. This function is accomplished in the embodiment of thelinvention shown by means of a connection between the upper or horizontal arm of the bell i crank lever 38 and the bracket 4l. Referring "to Fig. 2, it will be seen that said upper arm and bracket are so proportioned and relatively positioned that the arm slides out of the slot 40 at the 'instant the aligning pins 55 have reached substantially final aligning positionY but prior to setting of the clamping vbar 16 into a clamping position. The aligning pins then remain stationary in finalaligning position whileltlie clamp bar 16 descends to grip the strips thereunder. This 'permitsV free and unobstructed longitudinal aligning movement of the strips during the aligning action of the aligning pins 54. The clamping bar isset into clamping position upon the strips slightly after the aligning pins 54 reach their final rearward movement, wher-efl by the strips are gripped and positively held 1n correct position and smooth condition over `the platen for entry of an inscription thereon.

When the upper arm'of the bell crank lever 38 slides fromthe slot 40 of the bracket 41 during ascent. of the latter, the end of said arm contacts with the adjacent side'of the cam lug 40a which underlies the slot 40. This action prevents reverse movement ofthe bell crank lever thus locking the aligning pins in final aligning position. When the aligning ins are in inal aligning position one of the stop lugs or pins 61 is substantially in Contact with the adjacent bracket 48 as shown in Fig. 1 in full lines and Fig. 2 in dotted lines, so as to prevent the aligning pins from rearward movement beyond aligning position;

' this action also retains the upper bell crank lever arm in correct operative position relatively to the bracket 41. 'The other stop lug 61 as shown in full lines in Fig. 2, is positioned to contact with the .adjacent bracket A48 substantially at the opposite limit of the Arocking stroke of the carrier so as to limit A Y carrier movement in the opposite direction.'

When the entry is completed, the pedal is again depressed releasing the clamping bar and positively rocking the carrier in a counter clockwise direction as viewed in Fig, 2. As the pedal -is depressed, the end of the upper bell crank lever arm first slides idly over the side of the cam "lug 40d and subsequently the lug 4()b of the bracket 41 contacts with said upper arm to positively rock the bell crank lever counter-clockwise and thereby through the operative connections described, positively rock the aligning pins and carrier therefor forwardly from strip align-' ing position. During this movement the end of the upper arm of the bell crank lever isprojected into the recesses 4 0 in a position to overlie the cam lug 40L1 so as to be raised by the latter upon the return or upward stroke of the pedal. In this movement of the carrier, the trip contacts with the adjacent faces of the pin projections 55 so as to positively rock the aligning pins in a clockwise direction and thus positively withdraw the "pin projections from engagement with the CFI strip aligning apertures. If for any reason the strip should stick orl bind upon the pin projections, the engagement will be positively released by contact of l.the trips with the under side of the strips, that is, the trips function as strippers to positively remove the strips from engagement with the aligning ins. p The pedal being depressed, the strips mayy I then be manually pulled forwardly by grasping the forward ends thereof projecting into the aperture in the front edge of the cross plate 17, to bring fresh blank forms into position over the platen. The next successive 'strip aligning apertures are impaledv upon the aligning pins 20 and upon release of the pressure upon the pedal, the cycle of operations of aligning the strips as above describedr It is also to be understood that the-following claims are'intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
