BLAISDELL, OF BROOKLYN, NEW YORK, ASSIGNOR TO UNIOERWOOD PATENT OFFICE ELLIOTT FISHER COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE 'rvrnwnrrme MACHINE Application filed October 11, 1921' Serial No. 225,450.

The present invention relates to devices for inserting and gaging work-sheets to typing position at the front of a typewriter-platen. It may be advantageously applied to bookkeeping machines for making a condensed record of statement-sheets.

This invention relates to typewriting machines, and more particularly front-insertion devices used therefor. In the present invention there is provided a paper-table at the front of the platen, which, when in one posi-' tion, will aid in the insertion of a work-sheet downwardly into the typewriter at the front thereof. The'top edge of the sheet is fed down below a pair of normally disappearing pins mounted at the front of the typewriter, after which the table is pressed down a short distance so that the pins protrude therethrough, and the inserted work-sheet is pulled up against the pins for the purpose of aligning and collating the sheet with respect to the record-sheet. The work-sheet then being in position, the table is swung about its pivot to lie close against the platen. The swinging of this paper-table to its other position enables an operator to see the typing line clearly while typing, and also to hold the work-sheet against the platen and guide the same during line-spacing and prevent it from fallingforward;

Another feature of the invention is that,

during the swinging motion of the'papertable, the feed-rolls are either moved to their effective or ineffective position so that, after having typed a sheet, the paper-table is swung forward, thereby releasing the feedrolls, and the typed sheet removed and a fresh sheet quickly inserted at the front and aligned against the aligning pins, after which the paper-table is swung back against the plalten, simultaneously restoring the feedro s.

In carrying out my invention, there ispro-. vided at the front of the platen a slotted paper-table pivotally mounted on the opposite sides of the carriage. A plate mounted on the carriage-rail supports the table in a forwardly-inclined sheet-inserting position, slightly above its extreme forward position,

for inserting a statement-sheet and under lying carbon over the top of the downwardly-inclined table between a record-sheet previously fed around the 'platen from the rear, and a usual front apron of a rear paper-table, a fixed deflector-plate being disposed between' the bottom edge of the pivoted paper-table and the top edge of the apron. An operative. connection between the table and the usual lower feed-roll is eifective for releasing the feed-rolls when the paper-table'is disposed in its sheet-inserting position. \After the stateinent-sheet has been inserted around the.

platen, the table may be easily pushed down to its extreme forward position by pressure of the operatives fingers, while still gripping the leading'end of the statement-sheet. Upon the last-named movement of the paper-table two gage-pins, which are mounted on the r Y plate on the front rail of the carriage, project upwardly through the slots in the papertable. By pulling the leading edge of the statement-sheet up against the gage-pins,

and gaging its right-hand side edge against a side-edge gage fast on the paper-table, the first writing line of the statement-sheet is positioned to be subsequently disposed at the printing line of the platen, and the statementsheet is collated with respect to the record sheet. Then, while the operative gripsthe statement-sheet against the pivoted papertable, the latter is swung'to its rearmost position, which brings its lower edge above the printing line-and out of the paths of usual types moving to'strike against the platen. Upon rearward movement of the paper-table the above-noted connection between the table andthe lower feed-rolls causes the latter to be made effective. '1 A featureof the present invention resides in an arrangement of the operative connection between the pivoted paper-table and the lower feed-rolls whereby the connection is released when the paper-table isin its rearmost position, the feed-rolls being left free for operation by the usual feed-roll release lever independently of the paper-table.

v Another feature resides in the provision of means for inserting wide statement-sheets from the forwardly inclined paper-table without colliding with the usual type-guide.

- printing point with its top edge disposed as in its extreme forward These means include making the fixed deflector-plate substantially as long as the platen and positioning the plate at one side of the high as possible without interfering'with the lateral movement of the side bars of the carriage-frame. The platen will be moved alongside the deflector-plate for inserting thedstatement-sheet at one side of the type- Another feature is the provision of means mounted on the forward side of the pivoted paper-table for engaging a plate carrying the gage-pins and 'eldingly holding the papertable in its worl gsheet feeding position above the pins.

Other features and advantages will hereinafter appear.

Figure 7 is a diagrammatic view of a carriage of an Underwood typewriting machine havin my invention applied thereto, the carriage shown disposed in its extreme rightmost position for co-operation with the deflector-plate mounted at the right of the printing point for inserting a work-sheet at the front of theplaten from the forwardlyinclined front paper-table without fouling the typeide.

In an nderwood billing typewriting machine, types 10 strike against a platen 11 on a platemshaft 12 journaled in sides 13 of a platen-frame 14. A carriage 15 has side bars 16 and a front rail 17, the latter disposed forwardly from the platen. A segment 18 is fastened rigidly on the main frame members 18 and carries-a type-guide 19. A papertable 20 extends between the sides 16 of the platen-frame at the receiving side of the platen and has a forwardly-extending apron 21 which is provided with cutouts through which front feed-rolls 22 and rear feed-rolls 23 may engage against the bottom side of the platen. To release the feed-rolls, i. e., swing them away from the platen, a cross-rod 24 extends between the sides of the platenframe 14 and serves as a fulcrum for a pair of lever-arms 25 and 26, which are springpressed toward the platen and have their outer ends arranged for supporting axles of the feed-rolls. The arms 25 and .26 have integral, depending extensions 27, 28 which engage against the rear and front sides respectively of flat cam-elements 29 of a feed-rollrelease rock-shaft 30, mounted below the rod 24 andhaving a crank-arm 30' connected by link 31 to a feed-roll-release lever 32. I

In one use of the typewriting machine embodying the present invention, a record-sheet 34 is inserted over the paper-table 20 around the platen 11, and its first line of writing gaged to the printing line in a way to presently appear, and may be held against the platen at the delivery side by paper-fingers 35. mounted on a paper-finger rod 36'and carrying pressure-rolls 37. The record-sheet may be line-spaced around theplaten by means of finger-wheels 38 or line-spacing instrumentalities, not shown, which engage a ratchet-wheel 39 fast on the platen-shaft 12. The parts mentioned hereinbefore may be the same as in an Underwood billing typewriting machine, except as hereinafter noted.

For convenience in inserting and'collating a statement-sheet 40 and an underlying carbon-sheet 41' at the front of the platen with respect to the record-sheet 34, a front paper or collating table, generally designated as 42, has integral rearwardly-extending le 43 pivoted on inreaching studs 44 in the si e bars 16 of the carriage. These studs may also serve to hold usual sto s 44 which arrest the upward movement 0 the platenshift-frame and may be threaded in the usual tapped holes for fastenin carriage. To fasten the ta 1e 42 against lateral movement relative to the carriage, while permitting lateral adjustment for a purpose to presently appear, a collar 45 may be fastened by a set-screw 46 on each stud 44 and be disposed against the outer face of the adjacent leg 43. There is provided in the table 42 two elongated parallel slots 47 whose axes lie in planes that intersect at right angles the axis of the pivoted table 42. Two brackets 48, each having an inverted V-shape, are fastened tothe front carriage-rail 17 by screws 49 and support a plate or bar'50 in which are fastened two gage-pins 51 spaced apart the same distance as the slots 47, and are sitioned so that, when the front paper-ta- Eli) 42 is swung to'its extreme forward position, the pins will project upwardly through the slots 47. To provide for adj ustably moving the pins toward or away from the platen.

the stops to the the plate 50 is fastened by screws 52 which pass through elongated slots v53 in said plate 50 to be threaded in tapped holes in the brackets 48.

For inserting the statement-sheet 40 andits underlying carbon-sheet 41 at the front of the platen, the work-face of the paper-table 42 is held in operative position slightly above the tops of the pins 51 (Figure 3) by a cushioning leaf-spring 54-fastened by screws at the center portion of the spring to the opposite side of the table from its work-face. The spring has both ends bent away from the table 42 for yielding engagement against the plate 50. In the work-sheet feeding position of the paper-table, the plane of its work-face is forwardly inclined a large angular degree froma vertical plane to be disposed in a convenient position for manipulating worksheets thereon, and a. forwardly-extending finger-rest or shelf 55 is then disposed substantially horizontally. While the paper-table 42 is in its worksheet feeding position, the plane of its workface intersects the upper end of the typeguide 19 and intersects the platen below the printing line. The lower portion of the table 42 is disposed in the paths of the types 10. To enable a work-sheet to be fed over sheet to typing position.

the table without colliding with the typeguide, it isa feature of my invention to move the carriage rightwardly to the end ofits travel and provide means at the right of the printing point for guiding the statementsheet behind the apron 21 after the sheet' leaves the table. To this end,a sheet-metal deflector-plate 56 is preferably mounted at the right of the typeide 19, and has a portion 57 curved para el withthe periphery,

of the platen and disposed closely adjacent thereto, and extends downwardly from adj acent the printing line to within close proximity of the top of the apron 21. A horizontal flange 58, integral with the curved portions 57, extends forwardly beyond the rear or inner edge of the table 42 when the latter is in .its forward position. The top of the flange may be used for gaging the recorddepending ear 59 at the left end of the deflector-plate is fastened to the segment 18, and a depending car 60, intermediate the ends of the deflectorin the form of an angle-plate 62, which may be riveted on the table 42 and have an u right flange 63 transversely disposed tot e feed-roll release-lever to be 0 table 42.. The inner orlower end of the flange' 63 is concavely tapered to have a slightlylarger radius than the platen and the tapered portion is positioned'to be disposed parallel to and within close proximity to the peripher of the platen upon swinging the paper-tab e to its-rearmost position. It can be readily seen that the side-edge gage may be made laterally adjustable, if desired, without adversely affecting any advantageous feature of the present invention.

It is usual, in inserting work-pieces at the front of the revoluble platen 11, to release the feed-rolls, as is illustrated in Figure 3. It is therefore also a feature of the present invention to provide an operative connection 7 between .the pivotally-mounted paper-table 42 and the feed-rolls 22 and 23, whereby swinging the table forwardly to work-sheet feeding position will automatically release the feed-rolls, and swinging the table to its rearmost position will first cause the feedrolls to be moved to normal efii'ective position and thereafter to be disconnected from the table 42, but still connected with the usual rated at will by the latter independently o the table. To this end, a stud-screw 65, having a reduced end portion 66, passes loosely through a hole in the lower end of the link 31 and is threaded into a tapped hole in the end of the crankarm 30, the reduced portion extending inwardly a short distance past the arm. The

right-hand leg 43 of the table 42 is provided I with an angular integral rearward extension 67, which may have an inverted V -shaped form, and which may include a forward member 68 and a rear member 69 of the extension (see Figure 3) The rear end of the member 69 has a short, integral, inreaching lug 70 which is arranged for engaging against the rear side of a link 71, whose upper end is pivotally fastened on a 'pin 7 2 fast in the extension 67. The lower end of the link,71 has a rearwardly-opening, upwardl -inclined rear end fastened to a pin 75 in the platenframe 14 and its front end to the link 71 a short distance below the pin 72. After the statement-sheet 40 has been gaged on the table'42, and the latter swung to its rearmost position, the link-71 and -the screw-portion 66 are disposed in the osition illustrated in .Figure 4. In this positlon, the weight of the table 42 acting downwardly about the pivotstuds 44 is suflicien-t toovercome the force of the light spring 74, which tends to swing the table clockwise by pulling the link 71 against the lug 70. I

' Upon initial forward movement of the table 42, to position it for removing atyped statement-sheet and inserting a new one, the

lug 70 and link 71 are swung upwardly, and,

at the same time, the link is pulled rearwardly by the spring 74. The joint action of the 110 notch 73, A light tensile spring 4 has its pin 72 and lug 70, coacting with the spring 74, is efi'ective to cause' the notch 73 to be moved into engagement withthe, reaching screw-portion 66. Further forward movement of the table 42 to its work-sheet-feeding position, causes the link 71 to rise and swing the crank-arm 30 and rock-shaft 30 counterclockwise, which is effective to release the feed-rolls 22 and 23.

.When a typed statement-sheet has been removed and a new one is inserted and gaged,

as described above, the operative, while grip ping the new statement-sheet 40 and carbonsheet 41 against the table 42 with one hand, as illustrated in the dot-and-dash representation of the table in Figure 3, will move with her other hand the table rearwardly. This movement is effective to swing downwardly the link 71, whose notched lower end is held by the spring in engagement with the screwportion 66, and is thereby effective for rotating the rock-shaft 30 clockwise and permitting the spring-pressed feed-ro ls to be moved to grip the statement-sheet against the platen before the sheet is released from the grip of the operatives hand on the table 42. A further continuous rearward movement of the table 42 swings the link 71 downwardly an additional amount, and the upwardly-im,

clined notch 73 rides off the'screw-portion 66. Upon further continuous movement of the table to its extreme rearward position, which is determined by" a lateral pin 7 7 in an upright integral car 78 on the right side of the table 42 striking a usual top flange-member 79 of the platen-frame 14, the link 71 is swung to the Figure 4 posit-ion by the lug 70.

Inthe last-named position of the notched link 71, the latter will not interfere in any way with the control of the feed-rolls by operation of the usual feed-roll release-lever, which arrangement is desirable for adjustingthe record-sheet to the printing line of the platen, a better view. .of the printing line '45 being had when the table'42 is inits rearmost position.

It isdesirable to provide that "in any position it may be disposed, the link 71, which is supported on the laterally-movable carriage 15, will not strike against the fixed deflectorplate 56, which is disposed closely adjacent the platen. To this end, the link 71 does not extend in a straight line from the srew-portion 66 to the pin 72, but is bent rearwa'rdly at 80 (Figure 3). It can be readilyseen that the rear extension 67 of the right leg 43 and the link 71 mayhave diiferentforms from thoseillustrated in the drawings without departing from the scope of my invention.

The pressure-rolls 37 are effective for holding the record-sheet 34 against displacement on the platen when the lower feed-rolls'are released. Sincethe pressure-rools are preferably disposed adjacent the side edges of the record-sheet, which is usually considerably wider than the statement-sheet, it' is desirable to have means for holding the leading end portionof the statement-sheet 40 against the platen above the printing line to assure good typing impressions and to keep the statement-sheet from falling forwardly. To this end, the paper-table 42, while in its rearmost position, is held by engagement of the pin 7 7 on the platen-frame in a position which brings the work-face of the papertable slightly above the platen in a plane substantially tangent thereto with the lower edge of the table positioned a short distance above the printing line, approximately in line with the lower edges of, the pressure-rolls 37, which engage in rectangular notches or cutouts 81 in the lower edge ofthe table 42. The

notches are made extra wide to permit latdered by this construction of the deflectorplate, however, since the top edge of the latter is low enough to clear the bottom edge of the adjacent side bar 16 (Figure 4): By proper adjustment of the usual carriagestops' (not shown), the platen 11 may be moved laterally alongside the right end portion of the deflector-plate 56, when desired, for inserting a wide statement-sheet at the front of the platen without colliding with,

the type-guide 19.

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