To all whom it may concern Be it known that I, )LiLCoLu L. L' ossrr'r,

a citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful improvements in Manifolding Attachments for Typewriting Machines and the like, of which the following is a specification. My invention relates to manifolding attachments to type-impression machines comprising typewriters, calculating machines and the like, and its object is to provide a simple, cheap and eli'ective device adapted both for single and plural copies upon loose sheets of paper, without the use of ordinary carbon sheets, said attachment employing one or more manifolding members of approximately the length of the platen, and adapted to be either independently or collectively carried from an inoperative position into functional position between adjacent Sheets of loose paper, in the line or re gion of type impact.

Another object of my invention is to lock said manifolding members independently or collectively both in inoperative and in functional position. by means requiring such deliberate operation, as will insure safety both in and out of use.

Another object is to control the movement of the manifolding. members in their path to the line or region of type impact, so that they may reach their functional position and depart therefrom without interference with fixed parts of the machine.

Another object is to provide for the movement of the manifolding member with each line spacing movement of the'platen, in order to change its position with each line with respect to the line of type impact, thereby lengthening the life of said member.

Xnother object is to provide simple and efl'ective means for attaching and detaching the manifolding members to and from the r carrying members.

With these and other objects in view my invention consists in the novel manifoliling attachment which I rlltlll hereinafter fully describe. by reference to the accompanying drawings. in which- Fig. l is a top plan view of a portion of a tvpewriting machinm showing my attachment applied thereto, the manifolding mem' bers being in normal position of rest, out of use.

Fig. 2 is an end view from the left of my mamfolding attachment, the position being one of locked rest, out of use.

Fig. 3 is a similar view, showing the initial unlocking of the manifolding members.

Fig. 4 is a similar view showing the several members progressively moved forward about their respective individual axes.

Fig. 5 is a similar view showing all said members fully moved about their dual axes to reach a locked functional position in the line of type-impact Fig. 6 is an end view from the right of my attachment showing the manifolding members at locked rest, out of use.

Fig. 7 is a similar view showing said members unlocked and'progressively started towards their functional position.

Fig. 8 is a detail plan view, broken and partly in section, of one end of the machine platen and of my attachment.

Fig. 9 is a detail showing the attachment of the manifolding member to the carrying arm.

Fig. 10 is asection of the same on the line 10-10 of Fig. 9.

To avoid confusion, I shall first describe my attachment independent of the machine with which it is associated.

1 are-brackets, one at each end, Fig. 1. These brackets are formed with feet 2 adapted by means of screws 3 to be secured to the machine.

In the top of the bracket at the right, Figs. 6, T and 8, is journaled a short shaft 4, upon the outer end of which, as shown in Figs. 1 and 8. is fitted a hand wheel 6,to turn the shaft on its axis. The inner end of the shaft l carries a crank 5.

In the top of the bracket at the left -Figs. :2 to 5. journaled a short shaft 4. which at its inner end has a crank 5'. Between these two cranks 5 and 5' is carried l rod 7.

(p011 rod T as an axis is journaled a sleeve one or more, here shown as a nest of three. Fig. s. The innermost sleeve 8 is journaled directly on the rod, the next sleeve 5' is journaled on sleeve and the outermost sleeve 8" is journaled on sleeve 8'. Fuel: sleeve is in dependently turnable on its axis. The in nerinost sleeve 5 has liscd at each end an which a spring arm 9' and the has an arm 9". These arms for the sake of compactness as well as stiffness are angled, as seen in Fig. 1, and those at each end are nested respectively, the arms 9 lying outside, the arms 9" inside and the arms 9 between. A small finger-grip handle 10 is secured to the arm 9 at the right, another handle 10 to the arm 9' and another handle 10" to the arm 9", as shown in Fig. 1, the last named two handles fittin in open grooves 11, Figs. 6 and 7, in the middle and innermost arms respectively, so that the three arms lie nested snugly together when not in use.

Between the outer extremities of the arms 9 and carried thereby is a manifolding member, say, for example, a section of manifolding ribbon 12, a. similar section of manifolding ribbon 12' being carried by and between the arms 9' and a similar ribbon section 12" bein carried by and between the arms 9". See Ti 1.

It wfil now be seen that these manifolding ribbon sections are adapted, individually and collectively, to describe movements in s ace on arcs of two centers, one, indirectly, a out the short shafts 4 and 4 journaled in the brackets 1, and the other directly, about the rod 7 carried between the cranks 5 and 5'.

The former movement, namely that with the shafts 4 and 4' for an axis is effected by operatin the hand wheel 6; and in order to limit an define this movement at eachend thereof, there is secured to the short shaft 4 a two-notched stop 13, Figs. 6 and 7, with dctent l4 coacts. The upper notch of the stop limits the upward and backward movement of the shaft 4. as in Fig. 7, and the lower notch limits the forward and downward movement, as in Fig. 6. The second movement of the ribbon sections. namel that having the rod 7 for an axis is contro led by stop fingers 15, 15' and 15". Figs. 2 to l the finger 15 being secured to or formed with the arm 9, the finger 15' with the arm 9' and the finger 15 with the arm 9" (see Fig. 4) all at the left hand end. These fingers onset with a fixed stop member 16 carried by or formed with the left hand bracket 1, said member having an up per open ended guard groove 17 and a lower open ended guard groove 18. Figs. 2 to 5.

Journaled on a short stud 19 carried by and projecting inwardly from the right hand bracket 1 is a pinion 20, Figs. 6 and T. which carries on one side a cam 21. This cam operates within a yoke 22 pivotully carried upon and depending from the short shaft 4. The movement of the pinion is adapted, through the cam 21, yoke 22. spring detcnt 14 and notched stop 13, to impart a slightaxial oscillatory movement to the short shaft 4, for a purpose hereinafter made clear. The spring detent 14 is carried by the yoke 22, as seen in Figs. 6 and 7.

outermost sleeve at each end In order to rovide a simple and eflective means for readily attaching the ribbon sections to the arms and releasing them therefrom, there is, as shown in Figs. 9 and 10, a metallic clip 23 which at one side has a fold 24 which is pressed or crimped down u n the folded end of the ribbon section, an at the other side is provided with a bent tongue 25 which lies within and engages a notch 26 in the outer side of the arm. There is one of these clips at each end of the ribbon section, and the connection with the arms is made by slipping the tongue 25 either over or around the arm until it lies in the notch 26. The ribbon section is to be held under proper tension by any suitable means; in practice, a feasible way is by a slight yieldmg or resiliency of the arms so that by pressing them towards each other, the attachment of the clips may be made, and upon the release of pressure, the arms, springing back, will hold the ribbon taut.

his completes the description of my manifolding attachment. By now following its assemblage with the machine and its 0 eration in detail, the attachment itself will be more completely understood.

In Fig. 1 I have illustrated such portion of a typewriter as will sulfice for a proper understanding. 27 is the frame of the machine; 28 are some of the keys: 29 is the platen with shaft 30 and hand wheel 31 all mounted on the usual platen carriage; 32 is the spacing ratchet of the platen: 33 is the spacing; and carriage-returning lever; 3- is the pawl operated by said lever and engaging the spacing ratchet; 35 is the regular typing ribbon of the machine; 36 are the ribbon drums: 37 is the index pointer; and 38 is the paper guide-apron. In fitting my attachmentto any given machine the connecting members will be of such nature as to effect a proper union. It must therefore be understood that in the present case I illustrate and describe but one form of the structure and connections adapted for the union. n this case therefore. I remove the top bearings which hold down the platen shaft 30, and substitute therefor the feet 2 of the brackets 1 of my attachment, and I secure said feet to the platen carriage of the machine by the screws 3. as seen in Fig. 1. This simple connection completes the union of my attachment with the machine. As thus asscmbled. it will be especially noted. as seen in Figs. 6 and 7. that the pin on 20 of the attachment meshes with the spacing ratchet 32 of the machine.

It will also be noted by reference to Fig. 1. that the manifolding ribbons are independent single length sections of approximately the length of the platen and lie parallel therewith. and their dual axes of movement are parallel with the axis of the platen. The normal rest position of the parts, by

ber 16, as seen in Fig. 2, and this engagement locks all the arms and their ribbon sections from movement either forward or baclg, on the. rod 7 as an axis. Thus the ribbon sections lie parallel and close together, in an elevated, out of the way position; their carrying arms bein sn'ugdly nested as in Fig. 1. and all parts oek'e against any inadvertent movement.

Now let us suppose but a single carbon copy or duplicate be required. Two loose sheets of pa r, not shown, are ut in the machine, an turned about the lp ten until their upper edges are sufficient y advanced in front to be readily separated by hand.

Then the hand wheel 6 is turned backward thereby rotating short shaft 4, as in Fig. 7, which movement through the crank 5 and the corresponding crank 5' at the other end lifts the rod 7, with the arms and manifolding ribbons it carries This withdraws thestop fingers 15, 15 and 15" from the upper guide groove 17. of the stop member 16, as seen in Fig. 3, and this movement is limited by the upper-notch of the stop 13 engaging this s ring detent 14:. as in Fig. 7, w ile the ri bon sections are still su ported and revented from falling bao ward about tieir axis on rod 7, by the sto fingers resting on the" stop member 16 on sidethe guide roove 17. See Fig. Now the ribbon sections are all free to be brought into play, but as we are assuming that only one 18 required, the operator takes hold of the handle 10 of the arms 9" of the front ribbon section 12". This ribbon section is then turned forwardly and downwardly on its own axis on rod 7, describing an air which carries it down close to the front of the platen, and in a plane well inside and clear of the index pointer 37 of the machine, as seen in Figs. 4 and 7. which thus pre- 'scnts no interference; but its position just described is still above its functional position. The operator in thus bringing the ribbon section to its first position with reference to the platen. separates the advance edges of the two sheets of paper in the machine, so that the ribbon section 12" passes down between them.

Now the hand wheel (3 is turned forwardly again, until its short crank shaft 4 is limited b the lower notch of its stop l3 engaging tlie spring detcnt 14. This movement of the shaft 4 swings the rod 7 down again. with two effects. One ellci-t is to carry tluribbon suction stili further down etween the papersheetato its functional position in the: line of. type impact, as-seen in Fig. 5, and in this movement. it will be observed that as its axis .i's'the short crank shaft 4,

'said ribbon is caused to move slightly outwardly, thereby, as it moves down, well clearing the platen and affording room enough for the free line spacing movement of the paper sheets. In this final or func' tional osition the ribbon section 12" is locked y its stop finger 15 entering and engaging the lower guard groove 18 of the fixed stop member 16,. as seen in Fi 5. The other efi'ect of the movemcntof the shaft land the downward movement of the rod 7, still assnmingthat only the one ribbon section 12'' is to be used. is to return the stop lingers 15 and'l5' of the arms 9 and E) of the other two ribbon sections 12 and 12' down'a 'ain into engagement with the upper guarc groove 17 of the fixed stop 16, so that said'sections are still locked securely out of the we. while-the ribbon section 12" is in use. T is eflectcan be readily seen from Figs. 3 and 2, for if we assume that only the ribbon section 12 of Fig. 3 has been turned down to the position it occupies in Fig. i, then the turning of rod 7 to carrysaid section to the functional position of l ig. 5, will carry the other two ribbon sectionsof Fig. 3 down to the positionsthey occupy in Fig. 2.

A reversal of these several operations re sults in returning the ribbon section 12" to the position from which it started.

If two copies'ar'c to be made, three sheets of paper are put in the machine, and the operations above described are gone through with, except that the two ribbon sections IE and 12' are brought down and fitted between successive sheets, while ribbon section .2 is held locked up out oi use. So. likewise. if three copies are to be made. all three ribbon sections are thrown into functional position simultaneously. usscen in Fig. 5. in order to extend the life of the manifoldiug ribbon sections, provision is works (he y ke '3'. on lt pivotal connection 5th shaft -l. and lhis rocking of the yoke n.-(l|l;lll::' tlushort vl'unlc shut! 4 through the spring ill-tout l-l .(uriicil by said yoke. and llullflltlllll stop 1 on the Shufl. Suiil ilvlrnt and stop lll'lllll as u pnwl and Michel.

\l'ln-u rlw l'llllllll) sci-Linn is in use. this move-' meat of the crank shaft 4, has the eil'ect of changing the position of the rod 7 and thus changi the. position of the ribbon section with re ation to the type-im act line. By proper contour of the cam, e ribbon section may be raised slightly a few times at each successive line spacing, and than lowered slightly a few times and then raised again and so on, thus presentin eventually the whole surface area of the ri heir to the ty e impact.

n termin the manifolding members, ribbons" it is to be understood that said term refers to and includes'strips having a general'ribbon shape. They may be of any suitable material, and their preparation may vary. as. for example, they may have an im pression or ink surface on one side only, the other side being a non-impression one; or if it be desired to make one ribbon produce two copies one of which is a tissue paper sheet to be read by transmitted light, the ribbon may have both sides inked in the for oing description of the operation. it wil be noted that the swing of the mam-folding member, in describing its initial downward movement. is such as to carry its stop finger into position above the entrance to the lower uide groove 18 of the stop member 16, there y permitting its soonncl or final movement to 1 nctiona position relatively to the platen and to the line of type impact. Thus the manifolding member, to be used at all. must be brought into its positions correctly for if by chance, the stop finger should be bron ht down to lie outside the. aide groove 18, t c manifolding ribbon mm d be held out away from the platen and could not reach its proper place.
