TYPE-WRITING- MACHINE.

7 To all whom it may concern:

This inventlon relates to typewriting machines, and is especially adapted to be used in a front-strike typewriting machine, to enable work-sheets to be collated or adjusted relatively to'one another at the position most convenient tothe typist, namely, the front of the machine.

The invention is herein disclosed as applied to an Underwood typewriting machine. The platen is thrown up clear of the feed rolls, so that a work-sheet horizontally inserted may pass straight beneath the platen. The platen is thrown up rearwardly, thus providing ample space in which the typist may inspect and handle the work-sheets. The platen may normally tend to swing into its upper position, so that the typist may make ready the machine for the insertion of work-sheets by the mere release of a latch, which normally holds the platen down .to cooperate with the feed rolls in holding the work-sheets.

There may be provided one or more gages in the form of impaling .pins mounted on the front of the typewriter carriage, to cooperate with perforations in the work-sheets. The gage or pin may be located where it will not interfere with the manipulation of work-sheets in the ordinary manner in a typewriting machine.

The sheets one by one are laid face down upon a table or rest at the front of the carriage, with their rear portions extending under the platen. The sheets are collated in various relationships by means of the collating pins which rise from said table, to engage holes punched in the side margins of the sheets. Usually one .pin at each side of the table will be suflicient. After the sheets are collated, and while they remain engaged by the pins, the platen is swung :down to printing position, carrying down with it the rear portions of the sheets, until the latter are gripped between the platen and the usual bottom feed rolls. The sheets are thus always under control, and .may now be released from the plus.

Specification of Letters Patent.

The usual Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure '1 is a plan view of part of an Underwood typewriting machine, showing my invention as applied thereto.

Fig. 2 is a sectional end view thereof, the section being taken along the line 22 of Fig. 1. I i

Fig. 3 is a view similar to Fig. 2, the section, however, being partly taken nearer the center of the machine, and the platen being thrown up to enable a work-sheet, shown therein, to be adjusted on the collating pins.

Fig. 4 is a diagrammatic perspective view, showing a work-sheet adjusted on the platen.

Fig. 5 is a diagrammatic plan view, showing how a pliirality of work-sheets may be adjusted. v a

Underwood typewriting machine is provided with rails 1 and 2 on which slides the carriage frame 3', said frame forming a mounting for the platen 4, which platen is adapted to be rotated by the usual line-space lever 5 effective on the usual slide 6.

As shown in Figs. 1, 2 and 3, the platen is mounted on stub shafts 7 and 8, which are journaled in a swing frame, which includes feed rolls 15 and 16, into the upper position.

Application filed October 16, 1917. Serial No. 196,779.

seen in Fig. 3, in which latter position a,

work-sheet 17 is adapted to be passed horizontally beneath the platen.

When the platen 4 is swung up to the Fig. 3 position, one or more work-sheets 17 may be adjusted on a vertical pin 18, which is mounted on a work-adjusting table in the form of a plate 19 fast to the frame of the carriage, said pin being placed well inwardly from the frame so as to bring the pin as close to the printing line as may be without bringing the pin into a position where it will be awkward to adjust a work-sheet thereon. Y a

As shown in Fig. 3, the work-sheet 17, when impaled on the pin 18, will extend nearly horizontally rearwardly so that the farther end 20 thereof, which is the lower end of the work-sheet, may .reach toward and even beyond the usual paper table 21, rest- 'mounted on said side plate 10. *VVhen thus ing on the rear end thereof, as shown in .Fig, 3, To enable work-sheets to beaccurately adjusted, there may be provided a margin gage, which may take the form of a second pin 22 alined with the pin 18.

After the work-sheet 17has been adjusted to the desired printing line, the platen 4 is swung downwardly by drawing on a handle 23 formed as an extension of the side plate 10, and the platen-may be caught in "this lower position by a spring-actuated catch 24, which is adapted to catch over a pin 25 drawn down, the platen 4 holds the works sheet against the usual feed rolls. 15 and 16. During the operation of drawing down the platen'from its Fig. 3 positionfthe typist' may holdthework-sheet in position by placing a thumb or finger upon the plate 19. To .20

do this most conveniently, the handle23'is placed at the right-hand side of the machine to be manipulated by the right'.' hand, and

- the thumb or finger of the left hand may hold the work-sheet. I

After the platen has gripped. the work sheet against the feed rolls, the typ-ist may remove the finger or thumb from the plate 19, thus permitting the work-sheet to assume an upright position where it may be detained by abar '26. This bar is mounted near the platen and made, fast'in' the plate;

' 19 and supported at its right-hand end in an extension 27 of the plate 19, the bar 26 being sopositioned that it-is above the usual type guide 28 into which'the type-bars 29 (Flg; 4) strike,, and also above the wing asc ales 30, with the result that. the bar 26,

tending to bend them.

protects. both the wing scales and the ribbon vibrator (not shown), which is adja cent the type guide 28, in such away that even if the work-sheet is stiff, 'it will "not in- ]urethe'wing scales or ribbon vibrator by I 'In order that the bar may obstruct the new of the work-sheet as little as possible after be ng written upon, the bar 26 is madeas small as is consistent with the necessary strength, and may be in the form of a heavy wire having reduced ends '31, which are engaged by the turned-up ends 32 'of the plate 19 and of the extension 27.

The pin-18 is advantageously placed well within the carriage on a horizontal portion swings up and down in its. swing frame,

against overthrow when released from the swing frame.

'wardly under the pressure 0 'with the pins 18 and 22, and these pins 33,-

34' may serve either as impaling'pins or as margin gages. For removing or adjusting work-sheets, the feed rolls 15. and 16 may be provided with the usual casting-off mechanism 35.

To rotate the platen, there may be provided the usual knobs 36, which, in .the present invention, are usually 'mounted on stub shafts 37, and to enable both the knobs 36 and the line-space lever 5 to always have the platen under control, the platen may be 1 'constantly gearedthereto by mechanism somewhat analogous to the mechanism of the I usual fan-fold typewriting machines. :For this purpose, a stub shaft 37, which is conj nected both to a knob 36 and to the line- 1 space mechanism, is provided with a gear wheel 38 constantly in mesh with an idle pinion 39 journaled on the stub shaft 14, .8 and the platen shaft 7 is'provided with a gear Wheel 41, which is also constantly in mesh with the idle pinion 39. The connections, therefore, are such that .as the platen 9 the side plates thereof always hold the pinions 38, 39 and 41 in mesh with each other, thus keeping the platen always under the control of the rotating mechanism.

At the opposite end f l he carriage a similar idle pinion 42 may mesh with a gear Wheel 43 fast to the platen shaft 8 and with a gear wheel 44 fast to the usual other knoh-(notshown), thus preserving the symmetry of construction which conduces to the.

accuracy of the machine.

To facilitate-the operative in rapldly adjusting and -removing work-sheets, the

platen swing frame is adapted to be swung up vertically andjautomatically by means 'of spring 45, which bears against the slde pla 10, and may be coiled around the stub shaft 13. andanchored against a. pin 46 in the platen shift frame.

In order toprevent the platen from be-,

ing thrown too far over, the side plate 10 may be extended rearwardly at 47, forming an extension which strikes against the pin 46 to "limit the throw of the swing frame. The catch 24 may be operated by a fingerpiece 48, which is conveniently located I at the right-hand of the machine, and 006perates with a stop 48 to hold the catch By having the pin or pins 18, 22, 33 and 34 mounted on the typewriter carriage it ispossi-ble to locate'work-sheetson the platen, whatever the position of the typewriter carriage may, be along the usual scale plate 49. This makes it possible to utilize the bent portion 50 of the plate 19 as a rest for the finger and as a curve to guide thework-sheet when it is bein bent down the platen,

thus avoiding any tendency to form a sharp bend or ridge over the bar 26, with the reing pins at both sides of, the machine it becomes possible to collate work-sheets extending only part way across as is shown in said Fig.5, the sheet 51 extending only part way from the left, and the sheet 52 extending only part way from the right. It is possible for the typist to hold both these sheets against slipping whilethe platen is swinging down by resting the fingers of one or both hands 'on the upper part of the plate 19.

In order to enable the work-sheets to be rapidly and accurately adjusted without the need of the typist turning them over to inspect them, the lines on which writing is to be done below the usual cross rulings 54, maybe numbered as shown at 55,and

the perforations may j be correspondingly numbered on the back of the sheet, as shown at 56. It will be noted thatthe numberings 55 do not coincide with the numberings 56.

.The numberings on the back of the sheet are so placed that when a given numbering is at the pin l8, the corresponding numbering 55 on the front of the sheet will be atthe printing point when the platen is swung to its home position where the type 29- will write on the'face thereof. The worksheet s'hownin Fig. 4 is als shown provided with the usual, rulings 57, but the typist needpay no visual attention I to the adjustment of-said rulings with ref- 'erence to the scales on the wing scales of the I typewriten'if the machine is properly adjusted, and the perforations 58 of the worksheet are properly adjusted with reference thereto, since such proper adjustment brings f-it about that the impaling of a sheet on the pin 18 will bring the rulings onthe face of-the sheet in proper relations to thescal'es and escapement' mechanism of the type- I writer, a

The usual knob 59 on which the pointer 60 is mounted is preferably cut down to a i to. coijper-ate wlth a work-sheet adjusted on said pin, to enable the operative to adjust the I level with the top of the plate 19,- thus permitting a work-sheet to lie smoothly on said table.

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