JERSEY, ASSIGNOR T UNDERWOOD TYPEWRITER COMPANY, OF NEW YORK, N. Y., A CQBJPORATION OF DELAWARE TYPEWRITING MACHINE; I

Application filed September 27, 1920. Serial No. 413,035.

To all whom it may concern:

Be it known that I, BURNHAM C. STICK- NEY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention, in typewriting machines, relates to means for retaining 1n place in the machine a single general or condensed record-sheet, while permitting individual statements or bill sheets to be typed, withdrawn and others inserted and positioned in the machine relatively to the record-sheet, and has for its objects an inexpensive device simple in construction, which may be readily incorporated in an ordinary typewriting machine to a daptit for billing, purposes, and which will require only a minimum number of movements on the part of the operator to change the individual sheets, and which will assure a performance of the required successive operations automatically in proper sequence, thereby to accomplish the desired results While avoiding the liability of error.

In accordance with the present invention, preparatory to withdrawing the typed individual sheet and replacing it by another individual sheet, three distinct butcorrelated and interdependent operations are performed automatically and in proper sequence, by a single movement of a singlehandlemember. At a single stroke of the handlemember, first the platen is line-spaced to line-spacethe record-sheet, then a normally released gripping device is caused to grip and hold'stationary the line-spaced recordsheet independently of the bill or individual sheet, and then by the same continued movement or stroke of the handle-member the usual releasable feed-rolls are cast off from the plateh to release the bill'or individual sheet, while the record-sheet remains gripped, thereby providing for the removal or withdrawal of the-bill or individual sheet and its replacement by another such sheet, which may then be positioned relatively to the station-a record-sheet, which is held by the gripping device. The return movement of the same handle-member, at a single return stroke, operates to restore all of the parts of the machine-to their normal or typewriting position, and the automatic lineto perform any one or another of the required operations.

Other features and advantages will hereinafter appear.

In the accompanyin drawings,

Figure 1 is a plan view of a platen frame, and parts carried thereby, of an Underwood typewriting, machine embodying the present invention.

Figure 2 is' a front elevation of the same.

Figure 3 is an enlarged transverse section, with parts in elevation, on a vertical plane indicated by the line 3-3 of Figure 1 as viewed from the right with the parts in the normal position corresponding'to Figures 1 and2.

Figure 4 is a similar view at an intermediate phase of operation, in which the linespacing mechanism has been operated while the feed-rolls are still in their normal effective position, and the gripping device for the record-sheet is still in its normal ineffective position.

Figure 5 is a similar View in the final position of operation, showingthe gripping de vice in its gripping positio'n; -fo r holding the record-sheet stationary while the feed-rolls are cast off to provide for thefreplacement and positioning of the statement or bill sheet.

Figure 6 shows the manner of arranging the sheets when it is desired to have the type impressions from the ribbon fall upon the bill-sheet.

In the embodiment of the invention illustrated in the accompanying drawings, the usual rotative platen 1 has an axle 2 journaled in end walls 3 of the platen frame shown as of the usual Underwood type, and further comprising at the rear or introductory side of the platen 1 an inclined paper chute or paper-table 4,

shown as continued around below the platen 1 to form a curved platen shield or paperapron 5, a tiered 6 connecting the end walls 3 below the platen 1, and a transverse bar 7 extendii'ig between the end walls 3 above the paper-table 4: at the rear of the platen 1. Finger wheels or handle knobs are provided on the outer ends of the platen axle 2 for conveniently rotating the platen 1, which also may be fed in line-space direction by means of suitable line-spacing mechanism which may be and is shown as of the usual Underwood type. This line-spacin'g mechanism includes a slide 9 guided in its line-spacing movement to slide rearwardly on the left end wall 3, and which may be spring-pressed to its forward position by the usual spring, not shown. The slide 9 carries a line-spacing pawl 10 engageable with a line-space wheel 11 fixed on the platen axle 2 Line-spacing may be effected in the usual Way by means of the usual line-space lever or handle 12 pivoted at 13 on the typewriter carriage, of which a fragment is shown at 14, and having an actuating toe 15 engage-able with the forward end of the linespacing slide 9. The extent of the line-spacing movement of the platen 1 may be determined in the usual way by means including the usual upstanding adjusting lever 15.

v Below the platen 1, there is provided a rear set of feed-rolls 16, shown as three in number, and a forward set offeed-rolls 17, also shown as'three in number, co-operative with the platen 1 through openings shown as provided in the curved paper-apron 5. The rear feed-rolls 16 are mounted on a feed-roll shaft 18, and the forward feed-r0lls 17 are mounted on a feed-roll shaft 19. The rear feed-roll shaft 18 is carried by a pair of lever arms 20 pivoted on and projecting rearwardly from the tie-rod 6, and the forward feedroll shaft 19 is similarly carried by a pair of lever arms 21 pivoted on and projecting forwardly and upwardly from the tie-rod 6 in diverging relation to the rear lever arms 20. All of the feed-rolls 16 and 17 are normally pressed towards and into effective feeding relation with the platen 1 by means of springs 22 acting upon the lever arms 20 and 21, two of such springs 22 being shown in Figure 2 for the forward lever arms 21, and it being understood that similar springs, not shown, are provided for the rear lever arms 20, according to the usual Underwood constructiom A cast-off erlevice is provided for releasing the feed-rolls 16 and 17, and comprises a cam shaft 23 iournaled in bearings 21 on the tie-rod 6 and providedwith cams 25 en gageable with downwardly-projecting actuating lugs 27 on the rear lever arms 20 and similar actuating lugs 28 on the forward lever arms 21 as in the usual Underwood construction. At its right end the cam shaft- 23 is provided with a forwardly-extending cranlcarm 29 connected by a link 30 to a similar rearwardly-extending crank-arm 31 at the inner end of a short shaft 32 pivoted on the right end wall 3 of the platen frame, and provided at its outer end with the usual forwardly-projecting finger-piece The construction hereinbeforedescribed,

and to retain in the machine in stationary position a single general sheet or condensed record-sheet 3 1, while a statement, or bill,

or item sheet may be removed and re-' placed by another similar sheet and'each of these individual sheets 35 successively positioned relatively to the condensedrecordsheet 34, and it is highly desirable for convenience and saving of time that these changes may be made quickly and with as few operations or movements by the operator as possible. In the drawings the bill or item sheet is shown next to the platen 1, while the condensed record-sheet 3415 at the outside of an interleaved carbon-sheet 36 to be written upon directly by the usual types 37, as shown in Figure 3, by means of a usual interposed ribbon, not shown.

In accordance with the present invention, and as now to be described more particularly, it is only necessary to move a single handle member in one direction in order, by the single stroke of the handle-member, to line-space the platen, for producing automatically a blank space between the items or groups of items on the record-sheet 34, and, by a continuation of the same movement or stroke of the handle-member, to grip independently and separately hold stationary the record-sheet 34: in, the machine, and to cast off the feed-rolls 16 and 17 from the platen 1, while the record-sheet 34 remains gripped, so that the bill oritem sheet 35 is left free to be withdrawn from the machine and replaced by another similar sheet,

is securely retained in stationary position in the machine.

A single operating member or handlemember 38, provided with a normally upstanding handle-lever 39, is pivoted by means of a stud 40 on a forwardly and upwardly inclined supporting bracket 41, secured on the top and front of the platen frame end wall '3 at the left of the machine. Means operated by the handle-member 38 for automatically line-spacing the platen 1 to linefeed the record-sheet 34, thereby to produce automatically a blank space between the successive records thereon, will now be described. An operatin arm or lever 42 is pivoted at its upper en on the supporting bracket 41 by means of a pivot-pin 43 above and at the front of the pivot-stud 40, and at its lower end the operating lever 42 is rounded and bent slightly-backward and is I normally positioned just in front of the projecting end of the line-spacing slide 9, as shown in Figure 3, in position for operating the latter. The upper end of the piv oted operating lever lies between the supporting bracket 41 and the pivoted handlemember 38. At a point near its middle, this operating lever 42 is provided with a camstud or pin 44 which projects through a camslot formed in the handle-member 38, this cam-slot extending in a generally vertical direction in front of the pivot when the handle-member 38 is in the normal position, shown in Figure 3. This cam-slot has a lower straight inclined active or operating part 45 and a longer upper curved part 46 which is concentric with the pivot 40, so as thereby to form a dwell in the cam formed by the slot.

By moving forward the upstanding handle-lever 39 from the normal position thereof, shown in Figure 3, to the slightly inclined position thereof, shown in Figure 4, the straight or active part 45 of the above described cam-slot will act upon the pin 44 to swing the operatin lever 42 rearward from the inclined position thereof, shown in Figure 3, to the substantially vertical position thereof, shown in Figure 4, so that the lower free rounded end of this operating lever will push the line-spacing slide 9 rearward, thereby to effect line-spacing movement of the platen 1 automatically inde-' pendently of the usual line-spacing handle 12, and without the necessity of operating the latter, and which the typist would be liable to forget to do. Also it is clear that the usual linespacing lever 12 may be operated in the usual way to effect line-spacing movement of the platen 1 independently of thepperation of the handle-member 38. In

her"case, the extent of line-spacing move- ':of the platen 1 will be the same and is etennined in the usual way by the position of the line-space adjusting lever 15, and also, in either case, the record-sheet 34, the bill-sheet 35 and the interleaved carbonsheet 36 will be correspondingly fed forward. That is to say, all the sheets in the machine will be line-fed, although when the handle 39 is operated, the advancing of the bill-sheet 35 is merely incidental and is im material and of no consequence. During the operation of writing on the superposed sheets, the handle-member 38 and all of the parts controlled thereby are left in the normal position thereof, shown in Figure 3, and line-spacing between the successive typewrittemlines is effected in the usual way by operating the usual line-spacing handle 12. The handle-lever 39 is employed for line spacing when it is desired to move up the record-sheet 34, preparatory to replacing the bill-sheet 35 with another similar bill-sheet, so as to leave blank spaces on the record-sheet 34 between the successive items, 'or groups of items, corresponding to the different billsheets. The line-spacing movement of the handle-member 38 comprises about one-third of the. complete extent of movement provided for this member, and, at the completion of this one-third or first part of the movement of the handle-member 38, the con-.

centrically curved part 46 of the cam-slot will come'into engagement with the cam-pin 44, thereby permitting further or continued movement of the operating member 38 after the completion of the line-spacing operation as above described.

Means, now to be described, are provided to be operated, following the line-spacing operation, and by the further movement at the same stroke of the handle-member 38, for

automatically independently gripping and separately holding the line-spaced recordsheet 34 stationary and for concomitantly casting 0d the releasable feed-rolls 16 and 17, thereby to permit the bill-sheet 35, which has been written upon, to be removed and another bill-sheet to be inserted and correctly positioned relatively to the stationary record-sheet 34, which remains gripped.

The normally released, automatically operated, gripping device, or sheet-clip for holding stationary th record-sheet 34, will be next described. A rock-shaft 47, at therear of and below the upper downwardlycurved edge of the paper-table 4, is pivoted at its ends in bearing brackets 48 secured upon the top of the end walls 30f the platen frame. The rock-shaft 47 carries spring gripping fingers 49, shown as two in number, and positioned adjacent to the ends of the rock-shaft 47, opposite to the end parts of the platen 1, although, obviously, a

greater number of these gripping fingers resiliency, and thence each of these gripping fingers extends forward and downward below the upper part of the paper-table 4, and, adjacent to its lower end, is upwardl curved in rounded form, so as to be capab e ion I low the axis of, the pivot-stud 4:0 in the nor;-

is fixed on and extends downward from the rock-shaft 17, and is pivotally connected by a forwardly-extending operating link 52 to the pivoted handle-member or operating member 38 at a point rearward of, and bemal position of the operating member 38, appearing in Figure 3. Also it is to be noted that the pivot-point 53 on the operating member 38 for the link 52 is slightly below a line joining the axis of the pivot-stud 40 and the pivot-point 54 for the link 52 on the crank-arm 51, so that the operating member 38 forms a toggle with the link 52, It is alsoito benoted, from Figure v4:, that, after the operating member 38 has been rocked sufficiently to effect the line-spacing operation, as above described and as shown in Figure 4, the pivot-point 53 for the link 52 on the operating member 38 will be about as much displaced above a line joining the axis of the pivot-stud 40 and the pivot-point 5 1 on the crank-arm 51 as it was below this line in the normal position of the parts shown in Figure 3. By reason of this arrangement of theoperating link. 52, the gripping fingers as will not be moved to their gripping position during the movement of the operating member 38 to effect line-spacing, but will only be moved slightly downward and then back again substantially to the original position, while the pivotpoint 53 on the operating member 38 is moved past the center line of the toggle formed with the link 52, thereby assuring that line-spacing by movement of the handle-lever 39 will be completed before the gripping fingers 49 are brought into' gripping relation with the transverse bar 7 Further or continued forward and down ward movement at the same stroke of the handle-lever 39 through about another onethird of the complete movement provided,

therefor ,will result in elevating the upwardl -curved grippin ends of the gri ping 'ngers 19 througi the slots in t, e paper-table 4 into frictional gripping relation with the bar 7, with the record-sheet 341 rip ed and frictionally held against the ar by the gripping fingers'49. Yet further or continued forward and downward movement at the same stroke of the lever 39 will impart further clockwise rotation to the rock-shaft 47, as viewed from the right in Figures 1 and 2 and as seen in Figures 3, 4 and 5, and will press the yielding spring fingers 49 with greater force against the record-sheet 34, for clamping it more securely against the transverse bar 7, as shown in Figure '5.

' \Vhen the severalparts of the device are in the normal position, shown in Figures 1,

2 and 3, the gripping fingers 49 will be maintained at the ineffective or released position by the link 52. Preferably, the gripping fingers 49 should have a normal tendency to move to the released or ineffective position, and, for this purpose, a spring 55 is provided and is shown as a torsion springcoiled about the rock-shaft 4E7, this spring being anchored at one of its ends to the adjacent bearing bracket 48 and at its other end be- -ing connected to a collar 56, adjustably fixed upon the rock-shaft 47' by means of a set screw 57.

During the above-noted last part or substantially last one-third extent of forward and downward movement in the single stroke of-the handle 39, the previously effective releasable feed-rolls16 and 17 will be cast off automatically independently of and without the necessity of operating the usual finger-piece 33 of the cast-off device. The means for thus automatically casting off the feed-rolls 16 and 17 during the lastpart of the movement of the operating member 38 will nowbe described.

At its left end the cam-shaft 23 is provided with a forwardly and downwardly extending crank-arm or operating arm 58 to which is pivoted the lower end of an upwardly-extending operating link 59, the upper end of which is provided with a slot 60, forming a lost-motion connection with an operating stud 61, carried by the handlemember or operating member 38. The stud 61.is located farther from the pivot 40 of the member 38 than is the pivot 53 for operating the gripping fingers 49, and also it it to be noted, 1n the normal position of the operating member 38 and other parts of the device, as shown in Figure 3, that the operating stud 61 is' positioned at about the middle of the slot 60 of the link 59, and is located substantially in a straight line between the pivot-stud 40 and the pivot-point 62 of the lower end of the link 59 on the crank-arm 58. The lost motion thus provided in the slot 60 below the operating stud 61 provides for the casting oil of the feed-rolls 16 and 17 independ ently of the handle-member 38 and other parts in the usual way by means of the tinger-piece 33, as above described. The lost tion of the line-spacing movement, as illustrated in Figure 4, it will be noted that there is still a space above the operating stud 61 in the slot 60, and this further lost motion provides for the bringing of the gripping fingers 49 into effective gripping relation to hold the record-sheet 34 stationary, while the feed-rolls 16 and 1? are still ef fective, thereby preventing any accidental displacement of the record-sheet 34, which otherwise -might take place were the feedrolls cast off prematurely. During about the middle one-third part of the continued movementof the handle-lever 39, away from the position shown in Figure 4, the gripping fingers 49 will be elevated to the gripping position, as hereinbefore described, and also at the same time the remaining lost motion in the upper part of the slot 60 will be taken up.

Further continued forward and downward movement of the handle-lever 39, through about the last one-third part of its movement'and to the final position thereof shown in Figure 5, will lift the link 59 and rock the cam-shaft 23 to cast olf the feed-rolls 16 and 17, as shown in Figure 5.

I The statement or bill sheet 35 which, to-

gether with the record-sheet 34, has been written upon by the types 37, as indicated in Figure'3, is now free to be removed and may be replaced by a succeeding statement or bill sheet to "be likewise written upon, and so on for succeeding bill-sheets, the several items, or groups of items, corresponding t the different bill-sheets appearing upon the single, general or condensed record-sheet 34 in spaced relation by reason of the automatic line-spacing eifected through the operation of the handle-member 38, and

. the record-sheet 34 being securely held in stationary position in the machine during the replacing and positioning of the success1ve bill-sheets.

The swinging movement of the handle member or operating member 38 is limited by the ends of the cam-slot therein coming in contact with the cam-pin 44 at the initial and final positions, as shown in Figures 3 and 5. After each bill-sheet 35 has been inserted and positioned, then the handle 39 may be moved back from the final position shown in Figure 5 to the initialposition ment of the handle-lever 39, the operating lever 42 will be retracted by thelower part 45 of the cam-slot from the position of this lever appearing in Figure 4 to that shown in Figure 3,'there by permitting the linespacing slide 9 to be returned by its usual spring to the normal position. The feed It will be noted, from Figure 5, that, in

the gripping position, the spring gripping fingers 49 and also the return sprin 55 therefor will exert a tension on the linr 52, which will have a tendency to rock the loans die-member 38 away from its final position, there appearing, and towards its normal position. In this position of the several parts, illustrated in Figure 5, the operator should have bothv hands free for inserting and positioning the bill-sheet 35. A detent 63 is provided for holding the operating member 38 at its initial or normal position, shown in Figure 3, and also at its final position, shown in Figure 5. This detent 63 is shown as in the form of a fiat spring secured at its lower end to the supporting bracket 41, and, at its upper end, provided with a projection 64 engageable in recesses 65 formed in the adjacent face of the operating member '38.

38, either byactuation of the handlelever 39 or of the finger-piece 33 to release the member 38 from the detent 33, whereupon the spring 55 will return the handle-member 38 and other connected parts toward their .initial positions. It is apparent that the elfectiveness of the spring 55 will gradually decrease and become non-existent be fore the completion of the return movement, due to the downward movement of the pivotpoint 53 at the forward end of the link 52. The latter part of this return movement, after the handle-member 38 has reached the position shown in Figure 4, will be efi'ected chiefly by the forward pressure of the spring-retracted line-spacing slide 9 acting upon the lower end of the operating lever 42, as will be readily understood by a comparison of Figures 4 and 3. The spring detent 63 will retain the operating member 38 and its adjuncts in normal position and against accidental displacement therefrom, particularly during the independent linespacing movement of the line-space slide 9, efi'ected -in the. usual manner by the linesnace handle 12.

In carrying out the invention, as illustrated in Figures 1 to 5, the interleaved carbon-sheet 36 is'shown as passing above the transverse bar 7, so as to accompany the bill-sheet 35 to be released and removed therewith, to prevent smudging of the billsheet by the carbon. Also, in the form of the invention as shown in these figures, the

arrangement is such that the record-sheet (Figure 6) that the bill-sheet 35 wouldv be the outer sheet to receive the type-impressions from the ribbon, while the recordsheet 34 would be a carbon-copy underlying the bill-sheet. In the construction shown in the drawings, it is to be noted that there is one gripping finger 49 adjacent to each end of the platen 1 for engagin the recordsheet 34, which maybe wider than the billsheet 35, as shown in Figure ,2. With this construction, it is obvious that, if desired, the bill-sheet 35 could be passed down along the upper surface of the paper-table 4-and around the platen at the outside of the recoi'd-sheet 34 between and, because of its narrowness, so as not to be engaged by the gripping fingers 49, so that then the bill-sheet 35 would form a ribbon-copy. In that case, also the carbon-sheet 36 could be wide enough to be engaged by the gripping fingers 49' and held in the machine along with the record-sheet 34, which then would be a carbon-copy underlying the bill-sheet 35.

Also, the transverse bar 7 could be spaced farther above the paper-table 4, and the gripping fingers 49, together with their shaft 47, could be positioned above the paper-table 4, so that the bill-sheet 35 would then pass below the rock-shaft 47 and along the upper surface of the paper-table 4.

In view of the fact that the normally released sheet-gripping device, comprising the gripping fingers 49 and the bar'7, is independent of the platen, it is obvious that the individual bill sheets, such as 35, could be wide sheets of the same width or of greater widththan the record-sheet 34. Also, the independence of the gripping device from the platen provides for the insertion of the successive individual bill sheets to underlie the record-sheet 34 on the platen, as shown in the drawings.

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