To a u'lmnt it may concern:

Be it known that I, GEORGE W. DUNNING, a citizen of the United States, residing at East Orange, in the county of Essex and 5 State of New Jersey; have invented certain new and nsefill Improvements in Carbon Holders and Separato s; and I do hereby cleclare the following to be a full, clesr, snrl ere act description of the invention, such as will enable others skilled in the art to which it epperteins to make and use the same.

This invention relates to flat-pletei1 type writing machines, And more particularly to devices for holding and lifting or separating one or more carbon-sheets from the leten or work and-for clamping the paper W lch is to receive the impression to the platen, these parts being connected and heving operating mechanism by means of which they may be simultaneously raised for permitting arrangement of the work or lowered and held down while the impression is being made.

The invention also relates to certain details of construction for facilitating and perfooting the operation of the above devices and greatly expediting the work of the operator. 1

The object of my invention is to provide simple end effective devices for holding one ed e of the carbon-sheet, for clamping and holding the work on the platen, and for simultaneously raising seicl devices and separating the carboh-sheet through the medium of a foottrea.clle, a connecting-rod, crank levers, and other connections, for permitting the work, such as e statement-blank, to be conveniently removed from or applied to the piston in proper relation to the carbon-sheet without the necessity of handling the carbon sheet, whereb the work is expedited ens soiling of the ngers and the pa er are avoid ed and generally improved resu ts secured.

Another object of my invention is to pro vide for simultaneously raising and sepersti inggtwo cerbonsheets to different heights from the platen or papers which re'ceivethe pression to facilitate the insertion or removal of work/ 7 Another object of my invention is to pro vide for sup lying and clemping on the platen a thir carbon-sheet, preferably in a transverse direction in regard to the other carbon-sheets and the paper.

"Another object of my invention is to' provide for winding up and removing the carbonsheet from the face of the platen, so that the 7 letter may he used temporarily for other work.

Anotherobject is to provide for conveniently inserting or removing work or paper without the disadvantage of pushing the writing mechanism hecirte the rear of the track-frame.

Another object is to provizie for vertically and simultaneously moving the tape workhoirler and the (lemon-sheets to di'll'ercnt heights, so as to facilitate the insertion an}? removal of work, endrneens for keeping the tape worleholrlcr tent when it is soraised from the printing-surface.

Another object is to provide for the 35ltioning and movement of thecerh'on-slieet, which may be a. manifoliling paper or ribbon carbonized or otherwise provided with a transferring lnctlium of the some color or of different colors arranged in columns or pet-he, or where a. plurality of sheets are employed they each to heel dilferent colors, or have their surfaces provided with columns or paths of varying colors.

I preferablysupport the carbon-paper or other inenifohling material in a permanent fixture, such as a roll Inountei on the trecl frame, the platen, or table, and provide speciel devices, as above indicated, for holding, raising, and separating the free edge of the cerbornsheet for permitting the 4. Hick insertion and removal of the paper which receives the im )ressicn. The mper placed beneath therein oil-sheet, us well as that placed thereonto receive the lirst impression -mnst be firmly held to the platen before being written upon. For this purpose I provide certain paper-clamps, which will be hereinafter fully described. J

Figs. 15 and 16 represent detai views, on enlarged scale, of the lower and upper clamps or holders for the edges of the carbon-sheets; and Fig. 17 is,a detail sectional view of the spring-actuated spool for the work-holding tape.

My invention in its more sim 1e form enibraces in a machine a single 0 amp for the ed e of the carbon-sheet and suitable mechanism for lifting such clamp and at the same time liftin a paper-clamp from the platen or work whic is placed on the platen. This form of machine is illustrated in Figs. 1 to 5, inclusive.

The track-frame A (on which travels the writing mechanism B, having a forward and backward movement for line-spacing and also lateral movement for letter-spacing) is disposed upon the hinged plate a, which rests upon the table, (the sides of the said frame being perforated to receive a pin a .which passes through a standard a as shown in I igs. 1 and 2,) and within the frame A the platen U, is hin ed at c and otherwise supportthereof.

the platen and is held at itsfront free edge by the clamping device D, which is shown in perspective in Fig. 16, and is composed of the relatively stationary member (1 and the swinging member (1', which parts are pivotally connected or hinged at (l The opposite ends may be hinged or locked by the spring-catch d. "The swinging member (1 is preferably provided at its inner face with the inward-projecting pins or teeth d, and the other member d may have holes or de pressions, as shown in Fig. 16, for adapting the parts to better hold the carbon-sheet. The stationary member cl of the clamp D is connected to the outer end of the crank arm or lever F, as shown in. Figs. 1, 3, and 4. The carbon clamping and holding device D is located at or above the plane of the upper surface of the platen in order to prevent the carbon from being drawn down sharply over the front end of the laten, and to this end the clamp is preferabl disposed upon the platen. The mechanism for raising the clam J D and the paper-clamp K will now be described.

The crank arms or levers F and f forming one iece, are mounted on a rock-shaft f, whic is su ported in a suitable fulcrum member or )earing f, as shown in. Fig. 1. To the rear end of the arm f is pivotally connected the connectin -rod G, which at its lower end is connecte by a hook-and-staple connection 9 tothe treadle H, which is hinged A s ring f", connecting with the lever F an the platenor other ap ropriate part, tends to exert a pull u on t e lever F to reposition it een operated. The crank-arm F extends forward and parallel to the side of the platen and is made one of the members of a pair of lazy-tongs. The second mem ber I of this device is provided near the middle with an elongated opening or slot, (see Fig. 1 through which is assed a rivet f secured in the crank-arm Y The forward end of the member I is passed through an opening in the post 'i, which is secured to the table and is provided at its lower end with a coiled spring and at its upper end with an adjusting-screw for supporting the outer end of the member either in a higher or lower position. To the ends of the members F and I is connected pivotally at 'i and f the angular clamping device K, which fits over the edge of the platen, (as shown more clearly in Fig 5. This clamp K is L-shaped in cross-section, and the horizontal portion thereof is provided at its under side with flat spring-pressers k for more securely holding the papers in the clamp K is provided with inward-pro- 'ecting stop-pins k, as shown in Fig. 5, for bearing against the under side of the platen when the clamp is raised. The vertical portion of the clamp K may also be utilized as a Work stop or guide for feeding work up against it to insure perfect alinement.

The lazy-tongs device above described may be omitted and the clamp-piece K connected directly to the lever-arm F, as shown in Figs. 3 and 4. In this construction the outer end of the lever-arm is curved inward and has connected to it the carbon-paper clemp D. In this construction the swin ing member of the clamp D is ivoted at $1 to the fixed member, so as to e swung outward in a horiand the outer end of said member is slotted and engaged by a pin (F, as shown iIrFigl 3. In this construction also the flat pressens rings is, applied to the under side of the c snip K, come more prominently-into use that is, the resser-springs 7c are moreedvantageous in this construction of the riciinneetion from the lever-arm F to the In addition to the clampin devices above described I provide work-ho ding tapesL, which are connected at their inner ends to sleeves Z, arranged to slide transversely on the rods 1 which are secured inthe side brackets a, as shown in F i s. 2 and The By means of the statement-blank W is ir cartedin position.

Ths'second carbon-roller E is mounted by i'ts'shsft e in the side brackets e", as shown in Figs. 6, 8, 9; end 10, and has wound upon it a. second carbonsheet, which at its front edge is held by the lower clamp M, Figs. 7 and 15. This lower clamp, like the chimp l), is located in the general region of the surface ol' the platen in order to obviate the sharp bending of the carbomweh, which occurs at the front of the platen when the front holder is disposed helow the platen. In case two ce rhom rollers are used both sheets of carbon-paper are drawn over the platen and are held at their front free edges in the clamps l.) and M. Certain tension devices 15*, preferohl in the nature of adjustable coneshaped hearingintles provided with lock-nuts, are provided or the shafts e and e of the carbon-rollers, as shown in Fig. 8 and more particularly disclosed in my concurrently-pending applies tion, Serial No. 143,421, filed February 14, 1903. The upper carboinpapcr clamp D is substantially the same in construction as that chose described and shown in Fig. 16. The lower cerbom aper clamp M is shown on enler ed scale in lg. 15 and is composed of the re etiveiy fixed member m and the swingi'ng member m, which is pivotaily connected or hinged at m to the fixed member, as sh'crsn in Fi s S and 15. A sliding collerrn is adapted or sliding over and holding the swinging member m to the fixed member. M is in the nature ot a s )lit rod. to the forward end of the crank-arm P, as shown in Figs. 7 and 14. The omnk-srms P and in are fixed'on a. rock-shaft p, as shown in Figs. 8 and 9, and in prsctice'ere pivotelly connected'h s; pin to a. eonnectingguide p, which wi i" connect with the foot-treadle I, "ivotcd to a. fioonhraclret G, as shown in Edge. 1 and 2. The lever erm P is provided at the front end with a turned-up portion p, in the upper end of which is provided a s ot 'p for receivin the outer end of the clamp M. A post p is a. 0 secured to the forward end of the lever-arm P for connecting with one end of the clemp'l); as shown in lug; 7. As

the rock-shaft p is pertlyroteted'by pressure on .the feot treedletheouter end 0 the lever-arm? will first raising the clamp D, while at the same time the other until the'tcrned-np enddp; of the lever P has been forced upwarda tcnce equal to the hei ht of the slot p,

be forced upward. It will be understood that be forced upward, thereby when the clamp M will clemp M remains stationery the cllamp M is not raised until the bottom of the s ot p bears against it, when it will be raised a suffioierrt distance to separate the lower carbonsheet from the paper and platen. The 11 per carbon-sheet engaged by the clamp D wi lbe raised to a greater height than the lower carbon-sheet en aged by the clamp M, so that both carb0ns eets will be separated from each other and from the paper, thereby permitting the sheets of paper to be readily removed or inserted between.

and below the carbon-sheets.

At the left-hand side of the platen, Figs. 8 and 13, are suitably mounted the spring paper-clamps N, which are secured to-therod n, having coiled springs n for forcing" the edges of the clampin -plates N in contact with the paper. A suitable handle for operating the clamp N is provided at the front end of the platen, as shown in Figs. 8 and13. The work-holding tape L, Fig. 8, s supported and operated as above described.

As'shown in Fig. 6, the carbonized sheet may be in different colorsthat is to say, each sheet may have a column or columns of color different from that of the body of the sheetor there may be transverse paths of different colors. There may be stripes of different colors lengthwise or crosswise of the sheet. In other words, it may for billing work, for instance, be desirable to have a narrow red stripe located approximately where it will be upon the credit-column of the statement-blank. By this means the credit amounts would appear in red on the duplicate sheet of the statement-blank just as on the original, as produced by the red ribbon of the type-writer.

It may be that-sometimes an extra carbon copy would be desired, as wliere billing is being done in connection with a statementblank, and a third cop is required. To this end a second carbonheet may be used, operating the same as the first, as described, and a paper-roller.

A paper-roller R may be secured to a shaft 1'', Figs. 8, 10, 11, 12, and-13, which is suitably The sup o'rted in the journal-bearin s s s.

sha t nmay be made hollow an will be supported at one end on the tapering pintle s in the journal-box or bracket .5, as shown in Fig. 12. The other end of the shaft T has seated in it a screw s*,upon which is placed a This sleeve rests in the journalr, into which is placed a set-screw s for providin the proper tension on the shaft 1'. A

thum -nut s is applied to the outer end of the screw 8. By removingthe thumb-hilt and the set-screw s the shaft r maybe re moved from its bearings for winding upon it a sheet of paper or carbonprfor removing from it the old sheet. reference to Fi s. 8 and 10, theroller R is placed at one side of the platen and parallel surface of the platen.

As it will be seen 1) to the edge thereof, so that the sheet may be drawn transversely across theplaten, and in practice it will be the. lowermost sheet which is used in connection with the carboh-sheets, which are wound upon the rollers E and E. The sheet Y, Fi s. 8 and 13, is drawn transversely across t e'platen, and its outer free edge is held down on the platen by the clamp ing-plate T, which is secured to a rod t, supportedfiin the bearings a, and which is provided with coiled springs t for pressin the plate down upon the platen or carbon-s eet'. The rod t is provided at one end with a handle tlor raising the clamp-plate. -The edge of this plate is made sharp, so that the sheet may be readily torn oil, and detached. The sheet V may at any time be drawn forward across the platen by hand for exposing fresh surfaces thereof to the ty e. The clamp T, being at one edge of the aten, is out of the way 'of the longitudinal carbon sheets, a statement-blank, or other paper which is inserted on the platen.

The parts being constructed and arrangedas above described, the operation is very simple, and most of the parts will be operated by the feet through the medium of the treadle H, the connecting-rod G, and the lever-arms mounted u on the rock-shaft, as above described. I required,- the carbon-sheets when worn out or deteriorated maybe released from the clamping-lever D and slightly drawn forward and again secured in the clamps, so as to present fresh. surfaces to the type, the forward edges of the sheets; which project slightly by having been thus, drawn forward, being cut off at the clamps. Very little handling of the carbon-sheets.will b1. required, and since they are raised audiosered by foot-power the hands of the operator will be free for handling the statement-blanks or other pa ers to be remo. ed and inserted in .osition or receiving the impression.

' Ks shown in Figs. 1, 2, and 3, the statement-blank W is a loose unattached folded sheet comprising an upper and a lower meniber and is inserted by hand, the up er member being se aratedjfrorneits attac edlower member so icient to permit of its being positioned over the 11 per surface of the carbonsheet X, while t 1e lower member is posi tioned below this, the carbon-sheet this being interposed between the two members. To permit of this being done, the forward end of carbon-sheet is. raised by the mechanism above described,-as well the retaining device for holding the statement-blankagainst the {YVith the forr n of de- 7. and 8 this (inatvice illustrator in Figs...

the carbon-paper clamp D (carrying the carbon-sheet which is to be interposed between the two members of the billing-form W} are so arranged as to hove their forward ends raised to different heights, so that the upper carbon-shcet is positioned higher than the lower. This crmits the free insertion and withdrawn] 0 the billing-form W inoperative relation to the upper carbon-sheet with out disturbing the lower C8.Il)OIl-Sll88b.

By menus of these devices and the method of operating them the operator is saved the inconvenience of soiling his lingers and from soiling the paper sheets, and. his work is greatly expedited.
