3 Claims. (Cl. 197126) This invention relates to speed feed manifolding attachment for typewriters and other typewriting machines having a movable carriage provided with a platen for translation past a fixed typing location.

More particularly, the present invention deals with a manifolding attachment adapted for use with various types and makes of typewriters, and so arranged that it may be easily attached and detached whereby a given typewriter or other typewriting machine may be made available for manifolding and/ or other work.

The manifolding attachment of this invention is particularly characterized by the fact that it does not interfere in any way with operational parts of the typewriting machine, it being attachable to a reciprocating portion or member of the typewriting machine which is not an operational part.

The invention resides in a mounting structure for supporting the manifolding attachment in cooperating relationship with the carriage of a typewriter or similar machine, the manifolding attachment being supported independently of the typewriter but connected to the carriage for translation in unison with it; moreover, the

mounting structure is so arranged that the manifolding attachment may be disconnected from the carriage and lowered to an inoperative position in order that the typewriter may be utilized for normal typing operations when the manifolding apparatus is not required.

These advantages are brought about by providing a base member which is arranged to be placed upon the surface of the typewriter desk withthe typewriter resting upon it so that the weight of. the typewriter itself holds the base and manifolding attachment firmly in position. The base structure rises upwardly at the rear of the typewriter, adjacent its carriage, and is provided with a pair of spaced horizontal tracks which support a horizontally movable manifold carriage, the manifold attachment being mounted upon the carriage and rising above the platen of the typewriter so as to guide and feed the manifold sheets downwardly to the platen The manifold carriage at opposite ends includes releasable contact arms which extend toward and contact the opposite ends of the typewriter carriage so that the translatory movements of the typewriter carriage are transmitted directly to the manifold carriage, causing the manifolding apparatus to move in unison with the carriage during the typing operations.

standard typewriters vary from model to model in-the width dimension of the machine or its carriage and also as to the spacing or depth-of the carriage with respect to the rearward edgeof the machine frame. A distinctive feature of the present structure resides in provisions by which the manifolding attachment can be made to accommodate such factors by suitable adjustments but without any refabrication. In other words by making certain adjustments in the width of the attachment and its connection to the type.- writer carriage, the attachmentis capable of being applied to practically any commercial typ e-' writer. I

The objects and advantages of the present invention will be readily apparent to those skilled in the art; however, the nature and scope of the present invention and a manner in which it may be employed advantageously in a typical em bodiment thereof will be fully understood from the following description taken in connection with the annexed drawings, wherein:

In the drawings, like numerals refer to like parts throughout.

Referring to the drawings in more detail, it will be noted that the manifolding frame consists of two lateral members 2| which have internally directed flanges "22 which act as supports and guides for the carbon carrier plate (Fig. 6). These lateral members are connected by two transverse members 23, connected to the lateral members by bolts 24.

For the purpose of attaching the transverse members to the lateral members the ends of the transversemembers are turned in to engage the lateral members. These transverse members are braced by means of two diagonal braces 25, each having its ends riveted by rivets 26 to the transverse members as in Fig. 14 or, alternatively di rectly to the lateral members, as in Fig. 3. Where these-braces cross they are connected by a rivet 21 (Fig. '18), or they-may be brought together and spot welded as in Fig. 1,

On the lower end of each lateral member is a bracket -28 having a rearwardly extending portion 29, and said portion '29 is attached to an upright 30 mounted on the carriage 84 (Fig. 5). The upright 30 mounted on the right side of the carriage 84 (as viewed in Fig. 5) is provided with an outwardly turned ear 3| provided with a stop 3|aand adapted to be engaged by a hook 32 which is swingably mounted on the portion 29 of the bracket 28 by a stud 33. The hook 32 prevents back-tilting of theframe during use, but may be easily released to permit tilting back of the frame when not in use. The stud 34 mounts the portion 29 of the bracket 28 on the upright 30, and acts as-a fulcrum or bearing to permit tilting of the frame when desired. A two-piece shaft 35 telescopes -within -a hollow shaft 35a which extends across the back of the frame from the brackets 28, 29 mounted on each lateral member (Fig. 3). Each end of the shaft 35a is provided with a bushing 36 and wing nut 36a arranged to maintain the sections of the shaft '35 in predetermined extension according to the width of the body of the typewriting machine on which the frame is to beuse'd.

The typewriter illustrated has the usual platen 31a and the usualpaper release rollers 31b (Fig. 7) On the-lower endof the frame and supported by the lateral members is a shaft 38 (Fig. 14) which has thereon two spaced sprocket wheels 39. In the upper end of the frame and supported by the lateral members is a shaft 40 which has thereon two spaced sprocket wheels 4|. The sprocket wheels on the shaft 38 are connected to the sprocket wheels on the shaft 40 by means of sprocket chains 42.

Between the sprocket wheels 4! is a drum 43 forming a roller over which superimposed strips of paper pass. On each end of the drum adjacent a sprocket wheel 4| is a guide disc 43a which aids in aligning the strips of paper and holding them in alignment laterally as they pass over the roller during the operation of the typewriter. On the upper end of one of the lateral members is a housing or casing 44 which fits over one end of the shaft 40. This housing is supported on the lateral member by means of screws 45, and has therein a spring 46,. one end of which is attached to the housing while the other end is attached to the shaft 40.

A carrier plate 41 extends across the front of the frame and is supported by the inturned flanges 22 and is attached to the chains by means of bolts 48. On each end of the carrier plate is a bracket 49 attached thereto by means of a rivet which fits behind the inturned flange and prevents the carrier plate from leaving the frame (Fig. 12). Between each bracket 49 and the carrier plate is a spacer 5|. On each spacer, the carrier plate and the bracket 49 is a pin 52. lhese pins serve to support carbon carriers 53, each of which has at each end a hole surrounded by reenforcing material 54 to prevent wear due to engagement with the pin.

There may be any desired number of these carbon carriers, which are held in position by means of a spring plate 56, which has in each end a notch 51 adapted to engage in suitable notches 58 in the pins 52. As shown in Figs. 11 and 12, each of these pins has a plurality of these notches, whereas in the form shown in Figs. 6 and 15 each pin has one notch, and in order to take up the slack between the spring plate 56 and the outer carbon carrier, a sleeve 55 is provided for each pin. It is found more desirable, however, to use the plurality of notches rather than to use one notch with the sleeve 55.

The strips of paper are indicated by the numeral 59 and may be fed from a pile located at some suitable point behind the typewriter, and fed over the top of the drum or roller and beneath the platen of the typewriter. The carbon sheets 60 interleaved between the strips of paper are supported by means of the carbon carriers 53, one carbon sheet for each carbon carrier. On each lateral member, near the typewriter, is a guide plate 6| to prevent lateral movement of the sheets of paper as they are fed to the typewriter.

Attached to the chains at the back of the frame is a plate 62, which has at each end, at its upper edge, an ear 63 (Figs. 7 and 9). These ears are connected by a rod 64 which serves to hold the sheets of paper in assembled condition. At each end and intermediate the lateral edges of the plate 62 is an ear 65. These ears are connected by a rod 66, similar to the rod 64 and used for a similar purpose. At each end and at the lower edge of the plate 62 is an ear 61, to which is attached one end of a lever 68 by means of an ear 10 formed on a lateral flange 69, and a bolt ll passing :through the ears 6'! and 10.

The other end of this lever is bent to form a 513 flange 12, which engages the plate 62'when abet 525 the aligning pins 14 are in the holes in the paper for aligning the strips of paper. There are-two of these'levers, one at each end of the frame and at the rear thereof, connected by means of an angle bar '13 which extends to each side of the frame and may be gripped for releasing the pins from the holes in the strips of paper. The holes in the strips of paper are indicated by the nu merals 15. v

In the form shown in Figs. 11 and 12 there is provided at each side of the frame a guide plate 16 attached at each end to one of the transverse members 23. In order to hold the plate 62 against the guide plates there is provided at eachend of the plate 62 a clip TI which fits in front of the guide plate and holds the plate-62 in contact with the back surfaces of these guide plates. A spring 18 is provided for holding the pins against the sheets of paper or in the holes in which they project for aligning purposes. Thesesprings are attached to-the angle bar 13 and the guide plate 15. i

There is also provided in-one' of the lateral members an adjustable clip 8!) for use in determining when the holes in the strips ofpaper are in a position to receive the aligning pins. The strips of paper areseparated into separate tearoff sheets by means of creases or perforations 81, extending transversely across the strips of paper. "Each strip of paper is divided into sheets of the samesize by the transverse creases. The distance between the upper edge of each sheet of paper and the aligning holes is the same-for, all sheets and for all strips of paper composed of sheets. Instead of using aligning pins for entering the aligning holes 1'5 there may be provided on the angle bar 13, fingers 82 which will engage the strips in the creases (Fig. 13). 1

The numeral 83 represents a box of paper rest: ingon a table at the rear of the typewriter.- While a box is illustrated, none is required',,.and the paper stack may rest on the table top after being removed from its shipping box; Thispaper is composed of a plurality of superimposed strips folded along the creases. These superimposed,- strips of paper are fed over the roller or drum and beneath the platen of the typewriter; The aligning pins and the plate carrying these pins are located on the sprocket chains at the rear of the manifolding frame, so that the aligning is accomplished before the strips pass over the roller or drum, at the upper end of the frame.

In passing over the roller or drur njat' the upper end of the frame the strips become partially out of alignment, due to the variation in thediameters or curvatures of the strips. Howeveni-this lack of alignment is removed or compensated for by passingthe strips beneath the platen of the typewriter, where the curvature of the strips varies inversely as they vary in passing over the drum. By this means theholes of the strips are in alignment after the strips have been fed around the platen. This isillustrated in'Fi'g. ll, which shows the holes in the strips in perfect alignment after the strips have passed beneath the platen.

The purpose of this accurate alignment is that the writing on each superimposed sheet of the various strips corresponds in place and position to that of each of the others. During the process of writing the strips with the interleaved carbon sheets therebetween are fed for writing purposes. The free ends of the strips of paper, as shown in Fig. 11, move upwardly during the process of writing. After writing has been finished the while the strips of paper are in a position to be gripped and held against the platen. The paper release is brought into a position to hold the strips of paper against the platen. The angle bar 13 pushed backwardly to withdraw the pins from'the holes in the strips of paper. The platen is rotated to feed the strips of paper forwardly. This feeding operation continues until the creases at the lower ends of the next sections of the strips to be written on have reached the point indicated by the clip 80, at which time the bar 13 is released and the pins drop into the holes of the strips. Any further rotation of the platen will not only cause the strips of paper to be ad' vanced, but also the sheets of carbon interleaved therebetween. When the platen has been ro'- tated sufficiently to bring the creases onto the platen, the writing parts of the strips of paper are" torn ofi. The platen is further rotatedto adjust the oncoming sections of the strips of paper for writing purposes.

During this entire operation the paper has been touched by the hand of the operator only for the'purpose of severing the used sections from the strips. By adjusting the stops [9 and the clip'flll, the strips of paper divided into sheets ofvarious lengths may be used. v

As will be'noted by reference to Fig. l, the

frame is mounted by means of the brackets 28, 29 and the upright 30 on a movable carriage 84 arranged to move from side to side in unison with the carriage of the typewriter. Two-piece extensible contact arms 84a are provided at each end of the extensible shaft 35. A wing nut 84b fixes' 'the relationship 'of the two parts of the arm 8411. These contact arms, as shown in Fig. 2 are fixed bycontact against a non-operational portion of" the typewriter carriage, so that while thereby the carriage 84 and frame mounted thereon are caused to move from side to side accordingtolike movement of the typewriter carriage, there is no interference with any operational part of the typewriter.

As shown in Fig. 5, the carriage 84 is mounted on a-pair'of tracks 85 by means of wheels 86. The tracks 85 are supported on an X-frame B'i which'is' mounted on a pair of posts 88 arranged slidably to move through bushings 89, each of which is provided with a lock screw (not shown). Thebushings '89 are mounted on upwardly extending-wings 90 .of the base member or apron 9| which is arranged to receive the base of the typewriterand to be held in position thereby. 5:.Fig. lillustrates the manner in which theframe mayxbe. separated from the typewriter without necessarily disturbing either the frame or the typewriter. The wing nuts 84b are loosened, thus permitting thecontact arms 84a to move away from the carriage of the typewriter in the position or direction desired. This disengages the frame from the typewriter. The hook 32 is then lifted to disengage it from the ear 3| of the upright 30, whereupon the frame may be caused to tilt backward by swinging the brackets 28, 29 upwardly and thence backwardly using the stud 34 as fulcrum, until the lip 29a of the bracket portion 29 comes in contact with the stop .3la, whereby the frame will be held in an inclined positionextending outwardly to the rear of the typewriter and above the desk top, where it will not interfere in any way with the operation of the typewriter or the use of the desk. When it is desired again to make use of the frame, it is moved upwardly and thence-frontwise from its inclined position using the stud 34 as fulcrum, and then brought into position where the hook 32 again engages the ear 3|. The contact arms are then extended and brought into contact with the carriage of the typewriter, the wing nuts MD are made tight, and the frame is ready for use.

Referring again to Fig. 5, it will be noted that the frame 84 is provided with two protrusions 92 adapted to act as stops to prevent overriding. A latch 93 is affixed along the bottom surface of the lower track 85, and this latch will prevent over-riding by stopping travel of the frame 84 in either direction when travel has reached the point indicated by the corresponding protrusion 92. By moving the latch backward, either of the protrusions 92 may be permitted to pass, thus providing means for removing the carriage 84 from the tracks 85 when such removal is desired.

As those skilled in the art will fully comprehend, the combination of the base member or apron 9| and carriage 84 finds application, with or without the frame of this invention, in many other combinations than with a typewriter; however, such other uses need not be discussed here.

Those skilled in the art will also appreciate fully that the present invention provides an economical, practical, flexible, new and novel attachment for speed feed manifolding; and they will understand the many advantages which the present invention offers as compared with previous attempts to solve the problems here involved.

While the present invention has been described herein in certain specific embodiments, it has not been intended thereby to have the present invention limited to or circumscribed by the specific details of construction, arrangement of parts, operation, procedures, materials and the like herein described or illustrated in the annexed drawings; it being understood that the present invention is susceptible to modification according to individual conditions and preference without necessarily departing from the spirit of this disclosure and the scope of the appended claims.
