TYPING macnmn Application filed September 25, 1922. Serial 170. 590,268.

To all whom it may comm:

Be it known that we, Hnco A. Bunsen and AL'nnIomA. BnnrrRANn, citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Typing Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to improvements in typing machines, particularly machines of the fiat bed type.

ping machines wherein the bed or platen is flat and stationary and the typing mechanism'movable with reference thereto are applicable with peculiar advantage to use in conjunction with stationery of large size in one or more dimensions. Also, particularly where one dimension of the stationery does not exceed a given maximum value, such machines are well adapted to manifolding by means of interposed carbon or other copying sheets, webs or media. However, the full value of such machines for this purpose has not heretofore been developed due to inadequate provision for position control of the copying medium.

Thus in machines as heretofore construct ed ade uate provision has not been made for gui in or otherwise assisting in positiomng and adjustment of the copying medium in the direction of movement of the web of stationery, whereby the area covered by the copying medium is not accurately and permanently" defined. Moreover the method and means heretofore employed for securing the copying medium have been such as to require an inordinate number of time consuming operations for releasing, adjusting and resecuring the same.

An object of the present invention is that of providing in typing machines of the character aforeindicated, improved copying medium positioning and holding a paratus whereby the aforemntioned diflic ties and disadvantages are obviated.

Another and more specific object is'that of providing such apparatus w erein provision is made for insuring substantially rectilinear adjustment of the copying medium to any given or desired extent in either of two rectangularl-yrelated directions with reference to the position pf the stationery and in the corresponding reverse for directions at will, while also providin h sitioning and holding of the copying medium in relatively reduced dimensions and also in irregular shapes and sections, where re uired, with uniform results.

ther objects and advantages will hereinafter appear.

In the accompanying drawing, wherein is illustrated an embodiment of the invention.

Figure 1 is a plan view illustrating certain features thereof as applied to a standard typing machine;

Fig. 2 is a front elevational view of the same, certain portions being shown in section; while Fig. 3 is a detail view more fully illustrating certain features of the invention.

In the drawing is illustrated a typin machine bed 5 the typing mechanism ing omitted, said bed being preferably substantially flat and being assumed to be provided with one or more rolls for supplying there to in a well known manner super continuous webs 6 of stationery whic may include printed forms.-

Additional rolls 7 and 8 are carried respectively at the opposite sides of the bed 5 for holding respectively the fresh and the used or exhausted carbon paper or other copying medium, such medium being also in continuous webs and being run between the adjacent superposed webs of stationery. In practice the several webs of copying medium are preferably arranged in multiple ply relation upon the single rolls 7 and '8, whereas if desired "the various webs of stationery may be similarly arranged upon a sin 1e roll.

Said rol s 7 and 8 are preferably carried by and upon individual spools each spool having a central longitudinal bore for reception of individual supporting rods 9 and 10as'shown. In practice the spools are releasably clamped and positioned upon their respective rods for'movei'nent therewith as by the means illustrated, such means recesses in the ends of the spool in a well known manner.

The individual rods are preferably supported at terminally located portions thereof by spaced brackets 13 and 14 secured to and projecting outwardly from the bed portion of the machine and provide with suitable openings to receive the rod. The opening in the bracket 13 may preferably be circular and of a size such as to make with the rod an easy or rather loose working fit.

The opening in the bracket 14 may preferably comprise an open slot extending downward and inward with reference to the machine 'bed and having a relatively reduced transit portion 15 to permit radial passage of the rod therethrough and also having a somewhat enlarged circular portion 16 partially offset with reference to the portion 15 and arranged in coaxial relation to-the opening of the bracket 13.

Each of the rods 9 and 10 is provided with a rigidly secured handle member or portion 17 each handle further being provided upon its inner end with a counterbored portion forming an annular recess surrounding the rod. A helical spring 18 iscarr ied within eachof said recesses where as a plurality of annular spacers 19 are also strung upon each rod between the handle 17 and the adjacent collar 11, be-

ing' in practice forced against said collar by expansive force of the spring 18..

Said spacers are preferably tapered or substantially frusto-conical in form to pro vide annular partial interstices therebetween when pressed together. Moreover the size of the individual spacers is preferably so correlated with that of the enlarged portion 16 of the slot in the bracket 14; as to permit the spacer to extend partially within such opening, whereas the iat ter may if desired be flared outwardly to so receive the spacer under the force of the spring 18, such relation providing for releasable yielding locking of the rod within the enlargedrportion of the slot of said bracket and also for yielding restraint of the rod against timing movement with reference to the bracket. In practice the axial length of the individual spacers is preferably zso selected as to constitute an even multiple."

and preferably a unitmultiple, of the width of a single line of typing of the machine, although such relation is not absolutely essentlal. Thenumber of spacers employed said brackets is preferably mounted upon an elongated resilient securing element 21 and said securing elements are adapted individually to be sprung upwardly about the outer bed rails 22 of the machine as illustrated particularly in Fig. 2, for permanent retention of the brackets and their associated parts in assembled relationto the machine, such attachment and securement moreover being flCCOli'lPllSllECl without structural modification of the machine itself. Also if desired said elements 21 may be provided with suitably disposed openings to receive and fit about certain of the screws. bolts or the like, such as the screws 23 which are employed in the construction of the machine itself whereby still more positive securement may be effected but without structural modification of the standard machine parts or their assembly.

Said securing elements are provided at the lower part thereof with convexly curved surfaces 24 adapted to serve as guides for the web of copying medium passing therebelow. Here it may be observed that typing machines of the character herein contemplated are ordinarily provided with supporting feet or the like which serve to elevate the bed rails 22 sufficiently above the surface upon which the machine rests to provide ample space for the web of copying medium to pass freely between such surface and the guide surface 24. However, where such space is'insuilicientit is obvious that the same may be increased by increasing the height of such supporting feet or the like, or

optionally. feet 25 may be secured to the secured-to the lower ends of'the correspondingly disposed feet 25. thereby providing truck slots or slits for passage of the web.

In the operationofthe aforedescribed anparatus, adjustment of the copying webs laterally of the stationery is effected by simply turning the two handles 17 on the opposite sides of the machine in the proper direction, such rotation of One, handle serving to unreel the'copying medium from the fresh roll and the corresponding movement of the other handle serving to rewind the exhausted web upon the other roll, whereas,

ill?

turning of one handle alone in the proper direction provides for slack adjustment of the web and such adjustment will be maintained due to the frictional or braking interaction of the aforedescribed spring and spacers with the brackets 14. Y

Here it is to-be observed that the aforedescribed arrangement provides for accurate rectilinear lateral adjustment of the copying medium whereby the possibility of unwarranted shifting of such medium in a direction having a component parallel with the direction of movement of the stationery is prevented and the exact position of the medium with reference to the length of the stationery is definitely fixed.

Moreover particularly in the typing of forms and the like, it frequently occurs that "given areas of the copying medium are typed repeatedly whereas adjacent areas are impressed less frequently or not at all. In many instances such repeatedly typed area may comprise but a single line or a relatively small number of lines whereas under .such conditions when the copying medium corresponding to such restricted 'typed area becomes exhausted it is merely necessary to release the rods from the brackets 14 and shift the former together with the webs carried thereby axially, a distance equal to the width of one or more of the spacers 19 and thereafter re-engage the rods within the slots of said brackets. This adjustment serves to bring fresh areas of the copying medium into register without unwinding fresh medium from the roll, whereby the rate of consumption of the web is materially reduced.

Again it is to be noted that owing to the definite andaccurate control of the position of the copying medium the latter may for many purposes be employed in the form of relatively narrow webs whereby a further conservation of the medium may be effected.

In addition to the foregoing features it is also proposed herein to provide for accurate positioning and permanent retentionof separate sheets or sections of the cop ing medium. To such end are provide one or more thin supports or fingers 27, 28 extending across or substantially across the width of the stationery and adapted to carry in- 1 dividual sheets of the impression medium machine bed frame preferably in the manner illustrated in Fig. 2. Thus in practice a pair of spaced clips 29 may be sprung upwardly about'each bed rail 22 within the bent portion of the associated securing elements 21 and each provided with an upwardly and inwardly extending portion 30. Parallel rods 31 are secured to the corresponding projecting portions 30 substantially as shown. Each of the cross fingers 27, 28 is further provided with a slotted connector 32 mounted uponone of the rods 31 and normally slidable axially and angularly thereof whereas a suitable thumb screw 33 serves both to secure the finger to the connector and to clamp the latter to the rod in axially and an larly adjusted relation.

In practice t e opposite end of the cross finger is preferably free and where employed in conjunction with stationery which is open at both edges'the finger may conveniently extend an appreciable distance beyond the width of the stationery, thus affording at its free end a convenient handle whereby the finger and an stationery located thereabove may be lifte and separated from the'stationery or copying medium therebelow for. any desired purpose, such for example as the insertion of a sheet or card to prevent transmission of impressions to given areasv of the stationery located therebelow.

On the other hand the fingers such as 28 to be employed in conjunction with fan fold or other stationery which is closed upon one edge or upon both edges alternately are constructed somewhat shorter than the width of the stationery to permit the latter to pass about the former.

Thus when it is desired to transmit typed impressions to the successive layers of fan folded stationery, which form is obviously inadapted to the use of the transversely continuous web copying medium aforedescribed, it is nevertheless possible to utilize a suitable number of short cross fingers 28 extending alternately from opposite sides of the machine and each carrying an individual sheet of the copying medium folded or ed at one end about the finger, as shown in ig. 3, and extending in the direction of travel of the statione v By the a oredescribed use of the cross fingers it is apparent that'provision is made for accurate and permanent positioning of single sheets of the copying medium, whereby the same sheet when once inserted may be utilized without further attention in conjunction with a relatively large number of successive lengths of the stationery whereas heretofore in the typing of folded stationery it has been necessary following typing of each individual length to remove'the copying sheets therebetween and reinsert the same manually and individually, between the adjacent folds of the subsequent length.

Again where it is desired that the several copies be, not exact duplicates of one another, as where it is desired to suppress certain data upon individual copies, the cross fingers may be conveniently employed for carrying interrupted or mutilated sections of the copying medium, or in other cases blank sheets or cards to prevent the transill lit?
