Patented Feb. 27, 1934 UNITED STATES TYPEWRITING MACHINE Jesse A. B. Smith, Stamford, Conn., asslgnor to Underwood Elliott Fisher Company, New York, N.- Y., a corporation of Delaware Application October 20, 1931. Serial No. 569,915

20 Claims.

, This invention relates to work-holders and 3, sheet-interleaving means for front-strike typewritlng machines having round platens.

In my pending application No. 549,812, iiled 713"- July ,10, 1931, superposed carbon-sheets lie flat upon a work-table at the delivery side of the I platen. A line oi stitching connects the carbonsheets at their lower ends. The work-sheets are inserted one under another edgewise and between the carbons as they lie upon the paper-shelf.

The work-sheets rest upon the line of stitching.

Said stitching connects the carbons to a flexible binder-sheet, which extends from said table down around the front of theplaten, and is gripped by the feed-rolls, the latter holding the carbons steady while the work-sheets are being inserted. Each work-sheet is thrust in between the car- ,bons and merely dropped upon the stitches, and

is thrust to the left to a side-gage. go The uppermost work-sheet overlies the uppermost carbon, and'its lower edge is inserted under a tongue which extends up from the flexible binder-sheet.

An object of the present improvements is to provide for ready front-insertion of envelopes into the machine. This is done without having to remove the pack of carbons or subjecting them towear.

The flexible binder-strip carries a transverse flap some distance below the aforesaid stitching. This flap receives the work-envelop, the flap being placed at a point sufliciently low so that the typing on the envelop does not reach .up and overlap the carbons.

The binding trailer and envelop-carrier is reeniorced at a point below the envelop, to save it from injury to prevent wrinkling and creasing when fed around the platen. The binder-sheet is transversely doubled and stitched across, so as to form an upwardlydirected tongue serving as the envelop-clip. The latterextends about half an inch above the line of stitching.

During typing of an envelop, the accompanying work-sheet, just typed, may lie flat upon the table, in sight of the operator. The operator may copy the envelop directly from the heading on the letter.

When the gathering table, which is adjustably 5o pivoted, is swung down to the rear of themachine, the carbon-set with its binding trailer or coupling-flap and its two clips may be inserted, top first, at the rear of the platen by the aid of the usual paper-table, in the same manner as an ordinary work-sheet. The platen is rotated, thus (or. 197-126) g bringing the carbons up in front and entirely above the platen. The interleaving table is then restored to its operative position, and the carbons recline against said gathering table behind and above the platen. Then the sheets are inserted, Bil and the platen is rotated backward to bring the pack into typing position.

When the work-sheet clip is about even with the lower edge of the gathering table, the envelopclip projects somewhat above the usual front 65 wing-scale, so that the operator may easily thrust an envelop down in said clip, to rest upon the row of binding stitches. The platen may now rotate backwardly to bring the envelop to typing position.

Another feature is that the backing-sheet projects slightly beyond the right-hand side-edge oi the carbon-sheets, to Iacilitate the interleaving oi work-sheets between said carbons.

The gathering table is mounted upon the non- Ill shiftable carriage-frame of the machine, and is preferably hinged behind the platen upon said carriage-frame, so that it can be moved to a po- 'sition back of the typewriter. The hinged table tering-scale marked at its bottom, to facilitate the centering oi the heading of the letters to be manifolded.

Other features and advantages will hereinafter appear.

Fig. 8 shows in perspective the carbon-set element with the novel envelop-clip applied theretor Figure '1 is a sectional side-view showing the no t pack of carbon-sheets and interleaved worksheets in printing position around the platen.

Figure 8 is a sectional detail view showing the -the line of stitching 14 (Figure 6).

The right-hand upper corners of the carbons 10 are cut off and graded so as to form overlapping lips or margins 15, acting as guides for facilitating the interleaving of the work-sheet. A cutaway 16 is likewise made in the backingsheet 11 for simultaneous withdrawal of the typed sheets by grasping the corners thereof left exposed by said cutaway 16.

The right-hand edge of the backing-sheet 11' projects beyond the corresponding edge of the carbons 10 so as to form a right margin 17 facilitating the interleaving and gaging of the worksheets, as will be more completely described hereinafter. I

The lower part of the binding'trailer 12 is transversely folded at 18 and is stitched to itself at 19 so as to form above the lower transverse line of stitching 19 an upwardly projecting tongue or border 20 and a doubled trailing or coupling reinforced portion 21 under said lower line of stitching. This reinforced lower portion 21 of the binding trailer 12 is made wider on both sides of the carbon-set to accommodate envelopes wider than the work-sheet. The shoulders 22 thus formed, as well as the overlapping ends of the tongue 20, are preferably rounded toprevent their catching the paper-fingers of the machine. It will be noted that the shoulders 22 which may be spaced above the top of the tongue 20 form with said top a graduated page-end indicator co-operative with the wing-scale to indicate when the typing is approaching the bottom of a work-piece held by the tongue 20.

By first swinging a sheet-gathering table 31 rearwardly to the vertical position shown in dotted lines at Figure 5, the operator may insert the. described carbon-set containing any desired number of carbon-sheets 10 downwardly (top first) at the back of a platen 23 over a papertable 24 until its upper edge engages rear feedrolls 25. The platen 23 is then rotated by means of one of the usual knobs 26 fastened at both ends of a platen-shaft 27 to feed said carbon-set into the feeding path formed around the front part of said platen, said carbon-set being guided by an arcuate apron 28 forming a continuation of the paper-table 24, front feed-rolls 29 and the usual wing-scale 30.

When the envelop-clip 20 emerges from the wing-scale 30 and reaches in front of the printing line, its normal position, shown in Figure 5, the operator stops this rotation of the platen, lifts the table 31 to the position shown in full line in Figure 1, and throws back upon said table the carbon-sheets 10 and their backing 11, which recline in front of the platen over the keyboard of the machine. The carbon-set now lies flat on the gathering table with its work-sheet clip 18 about even with the lower edge of the gathering table 31 and ready for interleaving the worksheets 32 to be manifolded.

As shown in Figure 5, in this position the oubled part 21 of the trailer or flap 12 is still gripped between the platen and the feed-rolls 25,29, thus'establishing a mechanical coupling between the carbon-set and said platen and insuring the parallelism of the stitching- lines 14, 19, and therefore of the clips 13, 20, with the platen-axis.

The feed-rolls 25, 29 now co-operate with the trailer or flap 12 to hold the carbons 10 steady on the gathering table 31, while blank worksheets 32 are inserted edgewise'one by one to interleave with said stationary carbons 10, as described in my said co-pending application Serial No. 549,812. The bottom edges of said worksheets descend first to a line of rest upon the row of binding stitches 14, and the sheets are then gathered against a pair of side- gage plates 33, 34, arranged at the left-hand side of the interleaving table 31. This gathering operation is done merely by pressing the sheets to the left as far as they will go with the aid of the margin 17 which prevents the interference with the right edges of the carbons.

The right-hand side of the table 31 is clear for the operators hand.

The last blank work-sheet 32 is placed upon the uppermost carbon 10 with its lower edge caught and clipped by the work-sheet clip 13.

When the work-sheets 32 have been interleaved with the stationary carbons 10, the platen is rotated backwardly in the usual manner to pull the manifolding pack thus formed down into the machine into position for the typing of the first line thereon.

The usual swingable center paper-finger 35 is then swung in operative position to deflect the top edge of said pack back against the platen, so that it will fall down by gravity on the gathering table 31, as it is progressively brought back upon said latter to its initial position by the linespacing operations. The backing-sheet 11 is, though flexible, sufliciently stiff to insure that the pack will automatically bridge the gap existing between the lower edge of the table 31 and the top of the platen (as shown in Figure 7).

To aid the operator in centering the heading of the letter to be manifolded, a rear scale 36 is marked on the lower edge of the gathering table 31.

After typing, the paper-finger 35 is released and the manifolding pack is run further up by rotating the knob 26 until it reaches the position shown in Figure 5, in which the upper work-sheet clip 13 is about even with the lower edge of the gathering table 31, while the lower envelop-clip 20 emerges above the wing-scale 30, and the lower line of stitches 19 is still engaged behind said wing-scale.

In this position the operator may easily insert in front of the platen an envelop 37 down into said clip 20 until the bottom edge of said enveloprests upon the stitching-line 19, the top edge of the wing-scale aiding to clamp said bottom edge of the envelop in said clip 20.

The platen is now rotated backwardly to bring said envelop to typing position, the envelop being preferably held against the platen by means of -the paper-finger 35. v

The heading of the letter typed, readable on the top work-sheet 32, is thus brought down on the table 31 nearer the platen and well in sight of the operator, who has then merely to copy the address to be typed on said heading, as shown in Figure 1 After typing of said envelop, the operator releases the paper-finger 35, withdraws the envelop and grasps the upper right-hand corners of the typed work-sheets 32 between her thumb and her forefinger, and withdraws them from the I carbon-set by one stroke of her hand, due to the cutaway 16, provided in the backing-sheet 11. This easy and rapid removal of the work-sheet leaves the carbon-sheets in then-normal position assembled and flat upon the gathering table.

31, ready to receive a new set of blanks.

The platen-shaft 2'7 is journaled in two endplates 38 forming with cross-bars and operating levers (not shown) the shiftable platen-frame of the machine;

To avoid increasing the weight and momentum of said shiftable platen-frame which would result from mounting the gathering table Ell-directly thereon, said table is mounted instead on the non-shiftable carriage-frame 39, which is slidably mounted by means of guides 40 on the usual rails 41.

To mount the table 31 upon said carriageframe, use is made of two brackets 42, fastened to the cross-bar 39 under the paper-table 24 by means of screws 43, and projecting to the rear of said paper-table.

The board forming the table 31 is provided with two lateral downwardly-projecting flanges 44, a top flange 45, and a bottom flange 46, on which is marked the scale 36. These flanges serve as reinforcing ribs, suppress'the sharp edges of the table, and give to the same a neat appearance.

Integral with the two lateral flanges 44 are two downwardly-projecting ears 47 which are pivotally mounted between and in abutting rela-' tion with said brackets 42 on two collar-s rews 48. In a. circular opening 49 of theleft-hand side bracket 42 is riveted or otherwise fastened a socket 50, in which is guided the. rod or stem 51 of a plunger 52.v This rod 51 projects inwardly so as to form a cylindrical lug 53 and socket to hold the lug 53 engaged in either oi; H

' wardly from said platen and provided with an adjustable sheet-gathering side-gage, a manisaid holes 55, 58.

The lateral flanges 44 of the table 31 are fur thermore provided at each end with ears 58. in which are mounted two ilxed rods 59, lying unider the table close and parallel tothe top and bottom edges thereof. Each of said rods has on its under side a longitudinal groove or key way co-operating with key-projections 61 about the rods 59. The arcuate portion 63-of.

each gage 33, 34 acts as a spring to press the bot-. tom or body-portion 64 of the gage against the upper face of the table 31, while said ears 62 act as slidesto guide the gages along the rods 59 when it is desired to adjust said gages in position across the table. Springs 65, having U- shaped profile, are mounted upon the rods 59, between and in abutting relation with the ears 62 of each gage 33, 34, so as to press against said rods and to hold the gages in their adjusted position. v

When it is not desired to use the gathering and interleaving table, the plunger 52 may be easily pulled out'so as to unlockthe table 31, and this latter may be then swung downwardly in its abased position (shown in dotted line in Figure l) back of the typewriter for convenience in for supporting a work-sheet in flat condition, said around the platenthe lower edge of an extra mally held flat upon said table and coupled to said dropp said latter into the 'usual typewriter desk 9 Variations may be resorted to within the scope of the invention, and portions of the improve- I ments may be used without others.
