advantages will hereinperspective the carbon-ele- Figure 9 is an enlarged view of a part of Figure 5.

The drawings show an ordinary platen i ll journaled in end plates ll of its frame by means of a shaft l2 and operated by the ordinary knob it]. There is shown also the usual wing-scale M (Figure 5) and the usual paper-table l5, having an apron-extension iii. ll indicates the feedrolls and it a type-bar. According to the invention, a gathering table-element i9 is mounted on the end plates l l of the platen-frame by means of a hinge 2iiand brackets 2 l, removably secured to said plates ill by screws 22.

The box l 9 is held rearwardly and tangentially inclined above the front portion of the platen ill by means of lock-nuts 23.

The left-hand side 25, with sliders clasping the horizontal edges of the table it, is frictionally. mounted on the left-hand portion of the bottom of the box, and may thus be adjusted in parallelism.

Three carbon-leaves are illustrated in Figure 6, viz., 26, 27, 28, also a backing sheet 29, all being bound near their lower edges by means of a line of stitching 36, which secures the leaves to the top of a driving flap or tongue 31!, made of flexible but relatively stiff material.

This flap or tongue is substantially as wide as the carbons, and projects above the line of stitching, so as to form a clip or tab The right-hand upper corners of the carbons 26, 2?, 28 and backing sheet 29 are cut ofi and graded so as to form three overlapping lips or margins 3G, 35, acting as guides or insertionslots facilitating the interleaving of the worksheets. A triangular cutaway 36 is made in the backing sheets 29, for simultaneous withdrawal of the typed sheets.

The carbon-set, with its driving flap 3i, as

shown in Figure 6, is attached to the platen by introducing the device permanently between the platen and the feed rolls. It lies fiat, and may abut the gage 241. As shown in Figures 1 and 5, in this position thestitching is slightly above the lower edge of said box 09, and the driving flap 3i is still gripped between the platen and the feed-rolls ill, thus establishing a mechanical coupling between the carbon-set and said platen, and insuring the parallelism of the stitching 393 with the platen-axis.

The machine is now ready for the interleaving of the blank work-sheets. Presented by its lower left-hand corner, the bottom blank 37 is first inserted edgewise through the slot between the lowermost carbon 28 and the backing 29, and is simultaneously gathered to the left against thegage 2 5, and is also pressed down as far as it will go, i. e., until it is gathered against the line of stitching 30. A second blank 38 (see Figure 2) is then likewise introduced through the slot 34 between the carbons 2i and 28, and so on. The top blank' 40 is slipped under the clip 32 and laid directly upon the uppermost carbon 26, and is passed laterally and down until it abuts simultaneously the gage 2G and the line of stitching 30.

The blank work-sheets being thus gathered upon the carbons, the platen may be rotated in counterclockwise direction in the usual manner, whereby the assemblage of carbons and work-sheets is pulled down into the r'nachine, first by means of the driving-flap 3i, then by direct contact with the platen and the feed-rolls ll, until it reaches the printing position shown in Figure 7. During said movement, the top worksheet ill is kept in its registered position by the clip 32, which moreover facilitates the running of the manifolding pack between the platen and the feed-rolls ll.

After typing, the assemblage is again run up on the table, and the four printed work-sheets 3i,

38, 39, (iii are grasped between the thumb and the forefinger at their upper right-hand corners, and withdrawn as a unit from the carbon-set by one stroke of the hand, due to the cutaway 36, provided in the backing sheet 29.

This easy and quick removal of the printed sheets leaves the carbon-sheets still connected to the platen and in their original positions upon the interleaving table i9, ready to receive a new set of blanks. as the carbons endure.

When it is not desired to use the device, the lock-nuts 23 may be unlocked and the table it swung downwardly in a position (shown in dotted lines in Figure 5) back of the typewriter, more convenient for the dropping of the typewriter into the usual typewriter-desk; or the table element 59, with its attached parts 20, 2i, 23 and 24, may be easily removed from the platen-frame M by merely unscrewing the four thumb-screws 22 (Figure 3).

The backing sheet, which is numbered 29, aids in giving body to the assemblage, having some stifiness and thickness, and tends to keep the carbons from wrinkling and creasing, and also protects the platen from injury from the typeblows.

If desired, the carbon element may be inserted downwardly (flap first) in the machine at the front, by a suitable lip 29 provided upon the machine below the printing line, as seen at Figure 5, and shown in Patent No. 1,489,224.

The clip 32 holds the outer worksheet, and is convenient when inserting the device bottom end first at the front-downwardly around the platen, since said clip holds the bottom edge of the main work-sheet against displacement during this operation.

The carbon-element, however, may be inserted downwardly at the back of the platen, by first swinging the box or table-element rearwardly about its hinge, until the box takes the dottedline vertical position at Figure 5. This uncovers the ordinary work table at the rear of the platen,

The operation is repeated as long a and permits the ready insertion of the carbons, head first, downwardly at the back of the platen, and forwardly and up around the same.

One of the carbons 4| may be about two-thirds the width of the others, Figure 8, so that when typing a bill, the column of amounts will not be typed upon the underlying carbon-copy.

The clip has a further advantage, as it enables the operator, in case an extra carbon-copy is required, to insert and gather an extra worksheet with its loose carbon beneath the main work-sheet, so that all three of said sheets will be retained by said clip. Thus the capacity of the carbon-element may be temporarily increased as occasion requires, while it remains permanently connected to the platen for co-operation with the platen and gathering table.

The clip 32 forming a pocket in which the bottom of a work-sheet is seated, and being coupled to the platen by the flap 3|, constitutes an efficient page-end indicator to gage the untyped margin at the bottom of the work-sheets. In thus functioning the clip 3| co-operates with the printing-line scale l4. When the top of the clip M, which may extend substantially above the line of stitching 30, and thus above the bottom edge of the work-sheet, shows above or somewhat below the top of said scale, as may be easily discerned either at the usual printing-point gap (not shown), at the center of said scale M, or at either end of said scale, the operator is apprised thereby that the limit of typing which the work-sheet seated in the clip may hold has been reached or is about to be reached. Thus, there is obviated the liability of the typing running in unsightly proximity to the bottom edge of the sheet, The bottom untyped margins of the worksheets are neatly and uniformly gaged. It will be obvious that the device may function as a page-end indicator in the typing of single worksheets without manifolding, and that, for such use, the carbon-sheets may be omitted, the trail or flap 3i being in this case stitched directly to the backing sheet 29 to form the work-sheetseating and page-end-indicatin'g pocket or clip 32.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
