TYPEWRITING MACHINE.

Application filed March 14, 1923. Serial No. 624,889.

To all whom it may concern: I

Be it known that I, JEssE A. B. SMITH,

a citizen of the United States, residing in' Stamford, in the county of Fairfield and 6 State 'of Connecticut, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines of the fan-fold or continuous billing type, such as is illustrated in the Wernery and Smith Patent No. 1,132,055, dated March 16, 1915.

For use in connection with a continuous billing machine, in practice, it is sometimes desirable to have similar forms printed on different weights, colors and textures of paper. When this is done, it is obvious that the advantage is lost which might have been derived from printing the forms in repeated transverse rows on a single web, each row containing the same number of forms as there are copies desired; this lost advantage being the positive registration of all parts of the forms at all times when superimposed -over one another, due to their super-imposition being accomplished by longitudinally fan-folding the web on the longitudinal lines dividing the forms.

The use of different weights and textures of paper for making the work-sheets of a pack, and the absence of connection between the work-sheets along their longitudinal edges, which is'present in the longitudinally fan-folded pack, permits the work-sheets of a pack to creep on one another or to be fed unequally around the platen, thus throwing the forms out of registration.

One feature of this invention is the provision of means for initially registering and subsequently re-registering the forms on the continuous work-sheets of a pack at the conclusion of each typing operation that com pletes one of the forms, using the regular binding holes in the margins or edgesof the forms for that purpose, at the same time that the work-sheets are being gaged forsevering the leading forms therefrom.

Other features and advantages will here ina-fter appear.

In the accompanying drawings,

Figure l'is a front elevation of the platen and carriage of a continuous billing machine, which shows my invention mounte on the left of the paper-table.

to act as a pin 2 is a sectional view through the carriage of a continuous billing machine, showing the platen displaced in the usual manner, to allow the work-sheets to be straightened out for re-registration and gaging, and illustrates the manner of using myinvention to accomplish that re-registra- 1 igure 'tion.

Figure 3 is a perspective view of my reregistering device.

Figure 4 is a diagrammatic view of the leading edge portion of a continuous worksheet, showing how it is divided into sections bearing forms that have binding holes in their left edges.

As is usual in a typewriting machine of the continuous billing type, a platen 5 is mounted on a platen-shaft 6 which is journaled in a swing-frame 7 mounted in a movable carriage 8.. The usual feed-rolls 9 and 10 co-operate with a rear paper-table 11 to guide work-sheets underneath and around the platen 5. mounted on the swing-frame 7 serves to support the work-sheets as they emerge from the machine. Mounted on the rear of the carriage 8 is the forward end of a workpresenting frame 13 over which the worksheets are led to the entry or feed side of the platen.

Fastened near the center of the papertable 12, to move therewith, is a gage-bar 14 which carries an adjustable form-measuring and pin-finding gage 15. The gage 15 has a long leg 16 against which the leading edges of the work-sheets may be drawn, while in straightened position, to gage them for severing the leading forms therefrom, and finder for a ice-registering pin later to be described. The gage 15 may be fastened in various positions on the gagebar 14 by a thumb-screw 17. Fastened near A paper-table 12 I the side edge of the paper-table 12, to move therewith, is a supporting bar 18' similar to the gage-bar 14. Adjustably mounted on the supporting bar 18 is a re-registering pin-carrier device 19 having a long leg 20,

bent over near its end to form a projection d re-registering pin-carrier 19 may be fastened in various positlons on the supporting bar gularly to afford a positioned that it will be in 18 by a thumb-screw 25-. A web-severing knife 26 is fastened as usual in the swingframe 7.

The bar 18 supporting the pin-carrier 19 and pin 22 is mounted on a side gage bracket 35. One end of this bracket is bent anbase 36 to which the bar 18 may be attached. The bar 18 is held in fixed relation to the bracket by screws, rivets J or any other suitable fastening means, seated in the corresponding apertures 37 in the bar and bracket. The opposite end of the bracket 35 has an enlarged portion or foot 38, on the opposite ends of one edge of which are arranged angularly disposed fingers 39. These fingers aid in holding the supporting bracket 35 in fixed operative relation to its supporting member, when the stud bolt 40 or other fastening means is inserted into an aperture 41 provided for that purpose, in the bracket foot 38. The bracket 35 itself is mounted upon a connecting bar 42 oining the opposite ends of the swing-frame 7, and is in the position usually occupied by the ordinary paper side guide, the bracket 35 being in fact the usual side guide with its end laterally bent to provide the supporting base 36. The bracket 35, although acting as a support for the'bar 18, also performs its usual function of guide to the side edges of the paper pack, and thus has a double duty of side guide and support. By utilizing this bracket to carry the bar 18 with its adjustable re-registering pin, this pin is so accurate alignment with the perforations on the left marginal edge of the work-sheets, and will when adjusted properly function to effect the re-registering of the work-sheets expeditiously.

In operation, a pack 27 made up of worksheets 28, 29 and 30 is fed into the machine from the work-presenting frame 13. The work- sheets 28, 29 and 30 have forms 31 printed thereon which have binding holes 32 and 33 punched in one side near its margin or left edge, as shoWn in Figure 4. The worksheets 28, 29 and 30 may all be of different colors and textures of paper and have no connection with one another.

It will he understood that the work-webs are interleaved with carb n-sheets in any usual and convenient manner. But since the work-webs are provided with a series of perorations near one marginal edge thereof for reception of the re-registering pin, it is necessary to interleave the carbon-sheets between the work-webs, so that the body of the carbon-sheets will be to the right, of, or at least free from, these perforations. This is necessary in order to keep the perforations unobstructed and permit the reception of the re-registering pin therein and thereby permit the oamming action of the conicalshaped portion of the pin.

Assuming that this is to be an initial typing operation, and that the leading edges of the work- sheets 28, 29v and 30 are all selvage edges of fresh rolls of Worksl1eets, the leading edges are brought into registration and alignment and the platen lowered. The binding holes 32 and 33 of the first forms 31 will also be brought into registration by this operation and, of course, the forms 31 will be in alignment and register with one another too. The operator now advances the pack 27 until the first writing line of the first forms 31 is opposite the printing point of the machine, when the typing operation is begun. As the typing operation progresses, V. the operator linespaces the pack 27 until the matter is completely typed and the first forms 31 finished. The operator now releases the swing-frame 7 and lifts the platen 5 until the pack 27 can be straightened out and drawn forward. The leading edges of the work- sheets 28, 29 and 30 will have been shifted out of registration a trifle by the creeping of the sheets resulting from the line-spacing operation, but this is disregarded until the leading edge of the pack 27 gages the long leg 16 of the form-measuring and pin-finding gage 15. The operator holds the leading edge of the pack 27 against the leg 16 with the first finger and thumb of one hand and runs the thumb of the other hand along the edge of the pack 27 until the edges of the top binding holes 32 of the first forms 31 of the worksheets 28, 29 and 30' engage the conical surface 24 of the re-registering pin 22. The fact that the gage 15 and the structure 19 carrying the re-registering pin 22 are adjustable with relation to both the cutting knife 26 and to eachother enabled the operator previously to so position the gage 15 and the carrying structure 19 with relation to the various distances involved that, after the thumb has finished its stroke and after the conical surface 24 of the re-registering pin 22 has completed its camming' action against the edges of the top binding holes 32, the work- sheets 28, 29 and 30' will be firmly seated on the cylindrical portion 23 of the re-registering pin 22, with their leading edges all in registration again againt the leg 16, and, of course, with the forms 31 on all of the work-sheets also in registration with one another, as shown in Figure 2. The platen 5 is again swung to normal position in engagement with the feed-rolls 9 and 10 and the first forms 31 severed from the pack 27, after which the operation may be repeated.

Although the gage 15 and the carrier 19 with the re-registering pin 22' thereon are slidably adjustable on their respective supporting bars, and therefore to each other and to the web-severing device, it is to be clearly understood that during the typing web-severing gage operation the re-registering pin 22 and structure immediately carrying it is normally in a stationar Y or locked relation to its supporting bar. It is not used to draw the leading edges of the work-sheets to the gage 15. after the typing of each work-sheet form, but is set and locked in adjusted position and so remains until readjustment becomes necessary because of the change in size of the work-sheet form or the location of perforations thereon. In this respect the function and operation of the re-registering pin in the. present invention is in marked difference to that in my Patent No. 1,304,213, dated May 20, 1919. The re-registering pin device of that patent is specifically the means by which the work-sheets are drawn to the therein, and given their severing positions after the completion of the typing operation on each form. The reregistering pin device of that patent is not locked, and no provision is made for looking it. But after the movement of each form, following the typing operation, the reregistering pin device by gravity action automatically assumes its normal position at the base of its supporting or carrying arm, ready to effect another movement of the typed forms.

If the initial registration of the forms 31 is to be accomplished with Work-sheets from which the selvage edges have been torn, the leading ends of the Work-sheeets 28; 29 and '30 are brought into registration by cen tering the holes 32 of the leading forms 31 of those work-sheets on the re-registering pin 22, while the sheets are straightened out. This will bring the dividing line between the first and second of the forms 31 at the severing knife 26. The platen 5 may then be lowered to its normal position and the first forms 31 severed from thework- sheets 28, 29 and 30 and thrown away. operation may then be begun and be continued as outlined above.

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