Patented Aug. 27, 1935 UNITED STATES WEB SUPPLY CARRIER FOR TYPEWRITING MACHINES Tim Thrift, Elmira, N. Y., assignor, by mesne assignments, to American Sales Book Company, Inc., a corporation of Delaware Application July 28, Renewed 22 Claims.

This invention relates to improvements in record controlling devices for recording machines and with reference to some of its more particular features, it relates to improvements in record supporting and guiding means for use in connection with the typewriting and similar writing machines of the type employing a movable record or platen carriage.

It is a general object of the invention to provide for machines of the class mentioned an improved record guiding and controlling mechanism whereby records of the long, continuous traveler type may be conveniently used. By means of the improvements, record supplies of the long, continuous traveler type, either with or without continuous traveler carbon sheets, may be conveniently supported and guided into writing position upon the writing carriage, and are continuously maintained in correct alignment with the platen and with each other during the operative movements of the platen carriage.

According to another feature of the invention, an improved supporting and feeding arrangement for continuous traveler records is provided, being conveniently arranged for movements with the platen carriage so as to maintain the records always in correct alignment, and being adapted for attachment to machines of different size and varying construction, and being adaptable also to various types of desks or cabinets upon which the writing machines are mounted.

Another object of the invention is to provide for machines of the class mentioned an improved supply carrier and record controlling means readily attachable for operation by the platen carriage and connected to the latter so as to avoid objectionable shocks during movements thereof.

Another object of the invention is to provide for machines of the class mentioned an improved record carrying and controlling mechanism having a simple and advantageous supporting arrangement providing for quick and easy adjustments so as to adjust it for various sizes of typewriting machines and for different mounting arrangements therefor. By means of this special mounting arrangement, the record supporting and controlling mechanism is readily adaptable for use with typewriters mounted upon desks of the drophead type or upon other types of desks. By virtue of this improved flexibility of the record supporting and controlling means, the records can be continuously maintained in correctly aligned position upon a wide variety of different typewriter structures and of different mounts therefor, thus assuring satisfactory copies and satisfactory operation generally.

Still another object of the invention is to provide for machines of the class mentioned an improved mounting for a record carrier whereby frictional resistance is minimized, thus adapting 1931, Serial No. 553,557 July 3, 1935 1 the carrier for satisfactory operating movement by the typewriter carriage. In the embodiment of the invention herein shown, this desirable result is accomplished by means of a mono-rail support for the record carrier. With this improved supporting arrangement, the balance of the record carrier may be readily maintained by providing a supporting truck which is adjustable with reference to the carrier and the weight properly distributed upon the mono-rail support, even though the loading of the carriage may vary.

Other objects of the invention will be in part pointed out in the following detailed description of an illustrative but preferred embodiment of the invention, and will be in part obvious in connection therewith.

The invention accordingly 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 will be indicated in the claims.

For a more complete understanding of the nature and objects of the invention, reference is had to the subjoined description and to the accompanying drawings, of which:

Fig. l is a fragmentary side elevation showing the invention applied for use to a typewriting machine, parts being broken away and in section for more complete disclosure of the structure;

Fig. 2 is a plan view thereof, and

Fig. 3 is a section substantially on the line 3--3 of Fig. 1, looking in the direction of the arrows.

Referring to the drawings for a detailed description of the illustrative embodiment of the invention, the improved record supply carrier and controller is shown as applied to a typewriting machine shown diagrammatically at Ill. The record carrier and controller is adaptable to writing machines of different size and make, that shown being of a well known type having a movable record or platen carriage H carrying a rotary cylindrical platen l2 and mounted for transverse movement upon the frame l3 for effecting letter spacing in a manner well known in the art. The platen or record carriage l I may also be provided with a record guiding plate or apron 14 positioned for guiding the records or workwebs into writing position upon the platen i2.

While the improved record supply carrier and controller is adaptable for various forms of typewriter supports it is herein disclosed for purpose of illustration, as being attached to a desk or table I5 and is especially well adapted for application to desks or tables of the drop-head type wherein the typewriter is supported upon a cover or platform movably mounted so as to carry the typewriter in operative position, or to be adjusted to move the typewriter into concealed or non-obstructing position with reference to the desk.

For supporting the record supply carrier uponthe typewriter desk or other support, a supporting bracket l6 of improved construction has been devised. This bracket includes a supporting clamp ll adapted to be secured in position upon the edge of the table l and having a swivel support l8 rotatably mounted in the upper end thereof and held in adjusted position by means of a set screw 9. The bracket l6 includes a supporting arm 20 attached to the swivel support or extension 3 and having a lower fiat bearing surface in bearing contact with the upper bearing contact surface of the clamp II. This supporting arm 20 has a longitudinal bore in which is seated for longitudinal adjustment therein the carrier supporting arm 2| which is preferably flattened or splined as at 22 to form a bearing seat for a set screw 23 whereby the arm 2| is locked against rotation upon its longitudinal axis. This construction also provides an effective adjusting arrangement whereby the active supporting length of the carrier arm can be adjusted at will.

This adjustable carrier arm 2| has attached to the free or swinging end thereof a mono-rail mount or supporting device for the record supply carrier proper and embodying a mono-rail 24 pivotally attached for horizontal swinging movement to the end of the supporting arm 2|. As shown, the supporting connection for the mono-rail includes a supporting lug 25 welded or otherwisefirmly attached to the rail and having a supporting bearing aperture for the reception of the supporting pivot pin or screw 26. The end of the supporting arm 2| may be split or slotted as at 21 for the more convenient adaptation of the supporting lug 25.

The supply support proper as herein shown comprises a box-like supporting structure 28 constructed of light, strong material, such as wood or metal, and supported upon the monorail 24 for translational reciprocating movements therealong. A convenient and satisfactory type of support is shown embodying the truck support 29 attached to the underside of the carrier box 28 and having preferably two supporting wheels or rollers 30 grooved for the reception of the convex supporting surface of the mono-rail. These wheels 30 are preferably provided with anti-friction bearings and are appropriately attached to the truck support by means of the inverted U-shaped truck pedestals 3|. These pedestals as shown are conveniently formed by slitting the metallic supporting plate 32 and turning the supporting parts downwardly as clearly shown in Fig. 1. A guiding and retaining plate 33 is preferably attached to the truck support adjacent each wheel lying adjacent to the monorail 24 and having an angularly disposed part underlying the same so as to prevent accidental displacement of the truck 29.

At its opposite ends the truck supporting plate or bolster 32 is provided with longitudinal supporting members 34 having elongated slots 35 receiving attaching screws or bolts 36 whereby the bolster plate 32 is attached to the underside of the carrier box 28 for longitudinal adjustment thereof. The longitudinal bolster supports 34 preferably rest upon bearing plates 31 attached to the under surface of the box 28 and extending longitudinally thereof. Guiding and retaining plates 38 are also attached to the underside of the box 28 extending parallel and adjacent to the bearing plates 31 as clearly shown in Fig. 3 and retained in position by screws extending therethrough and through the bolster plate 32. Of course it will be understood that the retaining screws need not pass through the bolster plates 32, but if desired, may pass through the retaining plates only and extend therefrom directly into the box bottom. The longitudinal bolster supports 34 preferably extend at inner edges thereof slightly beyond the inner edges of the bearing plates 31 thus providing guiding channels for the reception of the guidingand retaining plates 38. By means of this arrangement, the supporting truck 29 can readily be adjusted longitudinally of the supporting box, thus to maintain its balance and to adapt it for different character of record supplies.

While various forms of record supplies may be used with the improved record carrier and controller, it is herein shown as being used with the long continuous composite traveler type of record indicated diagrammatically at S and transversely folded at intervals into a zigzag supply pack S which is housed and supported within the supporting container 28. This composite traveler record may be composed of as many superposed traveler record strips as desired and it is convenient also to use long continuous interleaved carbon or transfer strips for transferring the inscriptions to the lower record strips, thus avoiding the use of separate carbon sheet supporting means.

While the structure of the supporting container 28 may be varied for different types of record supplies, a convenient form for the accommodation of the zigzag supply pack S is herein disclosed. This structure is made of the desired proportions for the accommodations of the supplies preferably having a bottom and side end walls and an open top as shown. Adjustable supporting guides or partitions 39 may be utilized if necessary for the accommodation of supply packs of different widths or lengths. For this purpose the inner surfaces of the container walls are formed with groooves 40 providing supporting sets for supporting the partitions 39 in different positions.

It Will also be noted that the record supporting container 28 may be shifted 90 degrees in a horizontal plane merely by changing the position of the supporting truck 29 so that the length of the container as shown in Fig. 2 becomes the breadth thereof. This feature also affords a further opportunity for ready adaptation for different size or character of record supplies. Furthermore, this type of construction is well adapted for the accommodation of a plurality of supporting containers such as the box 28 positioned one above the other whereby each container may support an independent record supply. This is of considerable advantage when it is desired to use different record supplies or forms interchangeably upon the typewriting machine and for other purposes.

For guiding the record S from the supply into writing position upon the platen l2, an improved guiding plate 4| of metal or similar strong, light material is provided, being preferably longitudinally curved or cylindrical as shown and having adjustable edge guides 42 for receiving the longitudinal edges of the record. Either one or both of the edge guides 42 may be slid upon the guide plate 4| for adjustment for records of different width.

End supporting plates 43 are provided for the record guide 4! being appropriately secured thereto and having supporting lugs 44 and 45. A supporting rod 46 is carried by the lugs 44 being attached thereto by securing nuts and carrying attaching arms. The attaching arms 41 may be swung into different angular positions upon the supporting rod 46 and locked in adjusted position by set screws 48. Each attaching arm carries at its free end a rota'tably adjustable attaching block 49 slotted for the reception of the adjacent edge of the record guiding apron l4 of the typewriter carriage. As seen in Fig. 1 the attaching arms may be angularly adjusted to align the attaching blocks 49 so that the adjacent edges of the apron l4 may be received in the block slots whereupon the attachment to the apron is completed by tightening the set screws 50. A screw secures each block 49 to the respective attaching arm 41 whereby the block may be rotated to bring it into correct attaching position. The outer end of the guiding apron l4 may be received between the supporting rod 46 and the guide plate. Attached to the lugs 45 of the guide supporting plates 43 is an attaching rod appropriately secured in position to the lugs and extending along the rearward edge of the guide plate as best seen in Fig. 3. Extending between this attaching rod 5| and the adjacent edge of the record carrier or container 28 are attaching links 52 which are preferably in the form of fairly stifi bars or struts capable of transmitting movefments between the typewriter carriage and the 'supply carrier. They are also of sufiicient stiffness to maintain the supply carrier in its correct upright position upon the mono-rail support so that tilting of the latter is avoided which (may possibly be due to slight irregularities in loading or to other causes. Said struts are also sufficiently strong and rigid laterally to transmit energy impulses incident to operation of the typewriter carriage to the movable supply carrier to cause the latter to move in unison with the typewriter carriage.

As best shown in Figs. 1 and 3, the struts 52 are formed of two cooperating plates, one as the plate 53 being screwed to the carrier container 28 and the other plate 54 being attached for pivotal movement to the near edge of the record guide plate 4|. One of the strut plates, as 53, is formed with an elongated slot 55 and a securing set screw 56 extends through this slot and is threaded into the other plate 54. Opposed marginal guides 53' on plate 53 hold the strut plates in alignment. By means of this arrangement the connecting struts 52 may readily be longitudinally adjusted for the accommodation of typewriting machines of different height, relative to the supporting container 28.

For effecting the pivotal attachment of the struts the upper ends of the strut plates 54 are shown as being looped about the attaching rod 5| so as to slide freely longitudinally thereon. Buffer springs 51 are interposed between the loops of the plates 54 and lugs 58 adjustably attached to the rod. 5| being shown as spiral springs coiled about said attaching rod. It will, therefore, be seen that impulses from the typewriter carriage will be transmitted through the buffer springs 51 to the supply carrier. In this manner all shocks due to movements between the typewriter carriage and the supply carrier will be efiectively absorbed by these springs. Also, by virtue of this yielding power transmitting connection the movement of the record supply carrier may be substantially continuous whereas the movement of the typewriter carriage ordinarily is intermittent for effecting letter spacing in a manner well known in the art. The relatively quick intermittent movements of the typewriter carriage will be partially absorbed and stored by compression of one of the springs 51. The energy thus absorbed will then be delivered by the spring to the record carrier through the connecting struts 52. By this means it is unnecessary that the supply carrier be stopped and started with each letter spacing movement of the typewriter carriage. Shocks are thus avoidedand a smoother and more satisfactory operation is achieved.

It will now be seen in view of the above disclosure that the improved record carrier and controller not only is simple and practical in construction but it may readily be applied in operative position to typewriters of different construction and size and to different forms of mounting arrangements therefor. The effective length of the supporting arm 2| may be readily varied by the adjustable connection described for the accommodation of different distances between the attaching position of the supporting clamp I! and. the typewriter carriage. Furthermore, the angular position of the supporting arm 2| can be easily varied by swinging it upon its supporting connection l8 with the supporting clamp.

Also, it will be noticed that the supply carrier proper or container 28 is supported at the free end of the supporting arm 2| for rotation? and translational movements. This is accomplished by means of the mono-rail 24 pivotally connected to the arm 2|. Due to this rotational adjustment the mono-rail 24 may also be positioned substantially parallel to the movement of the typewriter carriage irrespective of the angular position of the arm 2 l the result being that the record'supply can at all times be translated along the monorail substantially parallel to the typewriter carriage. Removable stops 24' are preferably provided for limiting the movements of the supply carrier in either direction upon the mono-rail 24.

In use it will be seen that the improved record carrier and controller is very flexible in its adaptability to difierent operating conditions. An important result is that the supply record is at all times maintained in correctly aligned position with the typewriter carriage, practically no dis-- placement from this condition being permitted. This desirable result can also be accomplished without detriment to the free feeding movements of the typewriter carriage because of the improved form of support for movably supporting the supply and due also to the improved connection between the supply carrier and the typewriter carriage.

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 all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
