4 Claims.

My invention relates to typewriters and more particularly to an attachment therefor for carrying a supply of manifolding material to and fro in unison with the travel of the platen carriage 5 of the typewriter.

While it reciprocatory carrier operatively connected with the platen invention typewriter connecting justable to is quite old in this art to provide a carriage for unison travel, the present provides adjustable coupling means for interconnecting such traveling carrier with platens of different sizes, such intermotion transmitting means being adcompensate for different relative spacing between the traveling carrier and the typewriter platen carriage, and to further enable relative adjustment of the carrier and carriage longitudinally of their paths of travel and also provides an adjustable mounting for the travel-- ing carrier having improved anti-friction bearings.

The object of the invention is to simplify the structure as well as the means and mode of op eration of traveling carriers for manifolding ma terial whereby they will not only be cheapened positive in controlled of repair.

in construction but will be more eflicient in use,

operation, uniform in action, easily and adjusted and unlikely to get out A further object of the invention is to provide improved coupling means between the carrier and the traveling platen carriage of the typewriter.

A further object of the invention is to provide adjust able coupling means between the carrier and the typewriter platen carriage to enable the manifolding material carrier to be universally applicable to typewriters of different manufacture and of different sizes.

A further object of the inventionis to provide adjustable coupling or motion transmitting means by which different relative spacing between the carrier and the typewriter may be compensated;

A further object of the invention is to provide adjustable typewriter motion transmitting means whichwill enable relative adjustment of the carrier-and platen carriage longitudinally of their paths of travel preparatory to unison. reciprocation.

sizes. a I A furthe pedestal l for Nertical adjustment. The pedestal *1 is. slotted at 8 through which slot extends a clamp screws engaging with the rearwardly extending divergent supporting wings 6. The pedbase ill for to and fro sliding adjustment toward r objectof the invention is .toprovide --frameby means of an anti-friction mounting for the traveling carrier which will be economical in manufacture and which will enable freedom of movement whereby a minimum load or strain is imposed upon the typewriter platen carriage.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

Referring to the accompanying drawings wherein is shown the preferred but obviously not necessarily the only form of the embodiment of the invention, Fig. 1 is a perspective view of the typewriter attachment including the reciprocatory carrier, its mounting or support, and the adjustable coupling arms, forming the subject matter hereof.

Fig. 2 is a side elevation of a typewriter to which the manifolding material carrier forming the subject matter hereof has been applied. Fig. 3 is a detail side elevation and Fig. 4 an end elevation of the anti-friction bearing members and 25 their carrier or spacer member. Fig. 5 is adetail perspective view of the anti-friction connection between the reciprocatory carrier and its support,

Fig. 6 is an enlarged detailed fragmentary view of the carrier support. 30

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the accompanying drawings, I indicates a conventional form of typewriter of which 2 is the reciprocatory platen carriage. Mounted in the rear of the typewriter I for to and fro motion in unison with the travel of the typewriter platen carriage 2, is a basket or carrier 3 for a packet of manifolding material 4 which is progressively fed from the basket or carrier to the platen roll of the typewriter. The carrier 3 is mounted for reciprocatory motion upon a track member 5 supported upon rearwardly extending divergent wings 6 mounted upon a estal 1 is inturn' adjustably supported upon a and from the typewritten The pedestal is secured in its adjusted position upon the base it by the clamp bolt. The base It is detachably engageable with the rear portion of the typewriter *1 hooks i2 ,engageable This construction enables the manifolding material carrier or basket 3 to be adjusted both vertically and hori base l6 of the basket or carrier 3 is provided with similar dependent V grooved flanges II extending in complementary relation with the up-standing flanges it of the track member 5. For economy of manufacture the V grooved flanges l4 and I! are preferably though not necessarily of identical formation and are spot welded or otherwise secured to the track member 5 and to the base iii of the carrier or basket in reverse relation.

Interposed between the complementary flanges and seating within the registering v grooves thereof are anti-friction members It which may be either balls or rollers. Also interposed between the complementary flanges l4 and I! are perforated spacer bars IS, the apertures of which are located at spaced intervals with the antifriction members It projecting through such apertures into engagement with the v grooves of the flanges at opposite sides of the bars I 9. These bars l9 are free for longitudinal floating movement in unison with the travel of the carrier but at a different rate of speed.

To interconnect the reciprocatory carrier with the platen carriage of the typewriter for unison travel, jointed arms 20 are provided at each side of the traveling carrier for contact engage-' ment with the opposite sides of the platen carriage. The arms 20 are formed of interpivoted sections connected by clamp bolts 2| by which the sections of the arms 20 may be fixedly locked in adjusted relation. The arms 20 are also pivotally connected to longitudinally sliding bars 22 mounted in suitable guides on the under side of the base ii of the carrier or basket and adapted to be locked in their adjusted position by set screws 23. The arms 20 are fixedly looked upon the terminal trunnions of the sliding bars 22 in their pivotally adjusted positions by means of clamp screws 24. By releasing the clamp bolts 2| and screws 24 the arms 20 may be extended or retracted relative to the carrier 3 to accommodate the attachment to diiferent relative spacing between the carrier and the typewriter. After being adjusted to proper extended relation the bolts 2| and screws 24 are again tightened to hold the arms in such adjusted position. The arms 20 carry at their extremities fiber or other non-metallic contact heads 25 ,which have free sliding engagement with the lateral faces of the typewriter platen carriage. These contact heads 25 bear upon the lateral faces of the t'ypewriteg carriage and transmit the reclprocatory m'otio of the carriage to the manifolding material carrier. However the typewriter platen carriage is free for vertical movement independently of the arms 2| to enable the writing of capital letters in which case it is customary for the typewriter platen to be elevated.

The longitudinally adjustable bars 22, having sliding adjustment with the base it of the carrier enable the adjustment of the motion transmitting arms 20 toward and from each other and relative I with the typewriter frame and tightened thereon by the adjusting screws l3.

to the carrier to accommodate the device to typewriters having platen carriages of different width. This relative adjustment of the arms and carrier by sliding movement of the bars 22 upon release of the set screws also enables the carrier to be adjusted relative to the typewriter platen carriage longitudinally of their paths of travel and thus permits the carrier to be more accurately aligned with the writing position upon the platen of the typewriter.

These various adjustments of the arms 20 relative to each other and relative to the carrier, and the capability of the arms 20 for extension and retraction together with the vertical and lateral adjustment of the carrier support render the attachment universally applicable to typewriters of a wide range of sizes and proportions and of many difierent styles.

In the modification disclosed in Fig. 6, the bracket 6 is mounted upon a pedestal I for vertical adjustment. The pedestal I has a vertical slot 8' laterally enlarged at spaced intervals through which slot extends a pair of clamping screws 9' engaging with the rearwardly extending bracket 6. This arrangement permits the use of a straight bracket 6 instead of the wing bracket disclosed in Fig. l. The spaced headed studs 9 carried by the support bracket are insertable through the enlargements of the slot.

From the above description (it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement or parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect and the invention is therefore claimed in any of its forms or.modifications within the legitimate and valid scope of the appended claims. 1
