5 cut to me No. 1,999,535, issued April 30, 1935,

wherein a comparatively inexpensive box or casing made of cardboard, chip board, or other paper material is employed for containing permanently sealed within the same a pile of zigzag l folded continuous writing strips. In this type of register, which is to be discarded or destroyed as soon as its contained writing strips have all been used up, the box comprises telescoping upper and lower sectionssecured together to prevent the 15 box being opened without substantial destruction thereof. Such box or casing has a writing opening in its top and carries a platen or writing bed in the form of a shaped plate of metal or other relatively hard material below such openso ing; the manufacture of the casing being conducted and completed in such a way that when the box parts have been permanently joined as by cementing together the vertical walls of the 7 two telescoping sections, the work sheets of the as leading set extend over such plate and are exposed through such opening. The result is that when this once-use casing is delivered to the purchaser, the work sheets last mentioned are ready I for use and the leading edges thereof can be read- 80 ily grasped and advanced to bring a follower set of work sheets into writing position and, at the same time, to advance the work sheets of said leading set to severing position. i

One of the objects of the present invention is 35 to provide an improved metal writing plate having, among other advantages, novel cooperant re,- lations with other parts of the casing.

Another object is to provide a writing plate as' aforesaid, which also serves to provide means for 46 properly placing in the casing the required number of carbon or transfer sheets and for holding these sheets in such manner that the width of the casing need not be increased anywhere along its length beyond that of the width of the pile 48 of writing strips.

Still another object of the invention, aimed at the provision of a casing which will be less expensive but more rigid and rugged than heretofore, is to provide a novel type of lower section 50 for the casing such that the same requires a relatively small total weight of material, yet with this material so distributed that surprising strength and stiffness results in the finished lower section and particularly in the complete casing when the 55' other parts thereof are added, even when, as is now preferred, the upper section has all its walls merely single-ply sheets of fairly light weight chip board. In attaining this object in a. way now-preferred, the walls of the lower section are formed of corrugated paper board; these walls are all parts of a single folded blank wherein the corrugations run in the same direction; and yet each of the two side walls, both of which are of two-ply thickness, is so established from said blank that the corrugations of one of its plies run at right angles to the corrugations of the other of its plies.

Other features and advantages will hereinafter appear. I

In the accompanying drawings which show the form of this invention at present preferred- Figure 1 is a top plan view of an assembly as manufactured and shipped to the consumer for use, but with various parts variously broken away to illustrate details of construction.

Fig. 6 is a plan view of the blank and corrugated board which is folded up to establish all the walls of the lower section, but with the corrugations not shown. I

Fig. 7 is a fragmentary sectional view taken on the line 1-1 of Fig. 1 showing a detail of construction.

Fig. 8 is an enlarged detail view, showing con- 7 structionally certain elements omitted from Fig. 2 to simplify the latter where lines are necessarily placed very close together.

The device of the present invention, in the exemplifying embodiment thereof illustrated in the drawings, included a container or box having upper and lower telescoping sections In and II, the former being folded up from a single blank of chip board and the latter folded up from a single blank of corrugated board. This container, when the invention is carried out in the preferred way, has a width whichdepends upon the width of the forms, tickets, or other work sheets which are to be packed therein, the inner width of the lower section corresponding very closely to that of the width of such work sheets. ,Thus, the pile of zigzag folded continuous work or writing strips when the device is finally manufactured will be disposed in the box as indicated at I2 in Figs. 2 u

and 3, except that ordinarily the height of the pile will be considerably greater than that shown in these views to flll completely the storage capacity of the box.

Referring to the lower section ii, the same is folded up from a single blank of corrugated board. In Fig. 6, this blank is shown, so far as the outline thereof, cuts i3 therein, and scorings in thereon, are concerned. The direction in which the corrugations extend over the blank, when the walls of the lower section have their corrugations run as shown in Figs. 1 to 4, is that indicated by the double line ilb in Fig. 6. This blank is preferably so designed that when the portions H are folded up to form the end walls of the lower section, and the portions i5 are folded up to form one ply of the side walls of the lower section, thereby to establish the bottom wall ii of the lower section, and the four sections I'I at the four corners of the blank are folded up inside the side wall plies just mentioned and placed parallel therewith, to give each of said side walls a two-ply structure, edges of the two sections I! at one side of the blank will meet at the dot-and-dash line I511 in Fig. 6 and edges of the two sections I! at the other side of the blank will meet at the dot-and-dash line IS!) in Fig. 5. Then the corrugations of the inner plies of the side walls of the lower section II will run horizontally, while the corrugations of the outer plies of these walls, that is, of the plies furnished by the sections I1, will run vertically.

When these two plies of each side wall are secured together all over by a suitable adhesive, as is preferred, exceedingly strong and stiff yet light-weight side walls are provided. .In the lower section thus formed, the corrugations of the bottom wall It run longitudinally thereof as shown in Fig. 3, and the corrugations of the end walls ll run vertically as shown in Fig. 4.

Referring to the upper section Hi, the papermaterial walls thereof are desirably formed from a cruciform blank (not shown) of ordinary chip board to provide a top wall l8, end walls I 9, and side walls 20, all of single ply thickness.

As will be seen from a comparison of Figs. 1 and 3, box corner metal fasteners strips 21 are applied along the corner edges between the top and side walls of the upper section, these to act as longitudinal bracing ribs for that section; and similar metal strips, as shown also at 2| in Figs. 1 and 3, are applied along the four vertical corner edges of said upper section, these latter strips acting not only to establish the upper section as such by binding together the meeting edges of its side and walls, but, also, to incorporate vertical bracing ribs for the section. These fasteners carry a plurality of integral prongs (not shown) struck out from their metal incident to the formation of their lightener holes 2la, and these prongs are sent through the paper material of the walls of the section and clenched tight against the inner sides thereof.

Reverting now to the lower section III, in which connection see Fig. 4, similar metal fastener strips 2l' are applied to the four vertical corner edges of that section and similarly secured to the paper material of the walls thereof. Thus, the lower section Ii, like the upper section III. is provided with vertical bracing ribs along its four vertical corner edges.

a small half-round opening cut away at about the center of its upper edge, and the inner plies I! of the side walls of the lower section which are most remote from said half-round opening have portions cut away to provide very small rectangular recesses at the inner sides of these side walls. In Figs. 1 and 4, such half-round cutout is marked 22, and such rectangular cutouts are marked 23. These last will hereinafter be called the carbon holder pockets.

Such cutouts, which have to do with the facilities provided for the feeding of work sheets to writing position as hereinafter explained, are so located and are so relatively small that, as will be understood, their presence has no appreciable weakening effect on the lower section II.

The upper section H) has its top wall I8 cut away to provide a fairly long writing opening 24, which opening 24 is continued as a shorter and wider feeder opening 25. The opening 25 extends all the way to the top edge of the adjacent end wall IQ of the upper section 10, the central upper portion of which end wall has a cutout 26. This cutout 26 matches the half-round cutout 22 in the lower section II when the two sections are fully telescoped to complete the box.

It will be noted, referring to Fig. 1, that the right-hand limit of the writing opening 24 in the top wall l8 of the upper section is such that this opening is wholly to the left of the carbon holder pockets 23. It will be seen, also, that the writing opening 24 is of sufficiently less width than said top wall l8 to provide that fairly wide strips of such top wall, marked [8a, and stiffened by the metal corner fasteners 2| running therealong, extend not only lengthwise of the writing opening but also lengthwise of the feeder opening 25, to merge with the side portions of the adjacent end wall I! of the top section and thus provide top corner edges at opposite sides of said end wall.

Supported onthe lower section II, so as toextend under the writing opening 24 and the feeder opening 25 in the top section I0, is a writing plate 21 of metal or other relatively hard material. This plate is desirably made of light gage metal only about as heavy as that ordinarily used for the making of so-called tin cans.

As illustrated most clearly in Fig. 5, the writing plate comprises a main portion or writing plate proper 21a having a downwardly inclined ramp 2") over which the .work sheets pass toward writing position, this ramp terminating at its lower work sheet-receiving end in an undercurled edge portion 210. Along each of its sides the writing plate has dependent flanges 21d and 212, these flanges being staggered as shown best in Fig. 5, but so disposed that when the flanges 21d are close against the outer surfaces of the side walls of the lower section, the flanges 210 are snugly engaged with the inner surfaces of said side walls. Similarly staggered flanges 21d and 21h depend from the front end of the writing plate, these for seizing between them the inner and outer surfaces of the end wall of the lower section which has therein the half-round opening 22. Partially in the writing plate proper 21a and partially in the flange 21g is a substantially circular opening 211, the lower portion of which matches with said opening 22, as shown in Fig. 4, when the parts are arranged as there illustrated.

Registration of the forms on the writing plate may be accomplished in any suitable or desirable way. As here shown, each form is provided with 7 a pair ofform-registering apertures, and, for coaction with these apertures, the delivery end of the writing plate 21 is provided with a pair-of stopping and aligning pins '22. These pins, and also that part of the opening 211 ofthe writing section; this half-round opening 22 then matching as aforesaid the similar opening 28in the.

upper section III. 1 Y Referring to the carbon sheet equipment, the carbon sheet employed isa true or precut sheet 29. Fig. 1 shows two of these sheets in use. These sheets trail toward the delivery end of the writing plate away from their ends which are anchored to the plate near the receiving end of the latter. As shown in Figs. 1 and 8, each anchored end of a carbon sheet 29 is held between two leaves of a longitudinally folded thin metal strip 30, said end being tightly gripped between these leaves by indentations made in the upper leaf as seen in Fig. 1. The lower leaf of eachof. these holder strips is prolonged beyond the ends of the upper leaf, and each of these prolongations has a thin elongated slot a therein. These slots take small extensions 2': upstanding from the ramp 21b of the writing plate. These extensions have oppositely located ears 21m at elevated points thereon. In assembling the device, when the carbon sheet holders have been mounted to string their slots about the lower portions of these extension 211:, the ears of each such extension are oppositely twisted as indicated in Fig. 1, thus permanently to secure the carbon sheets in place. The prolongations of the carbon holders 30 which carry the slots 30a, are at their extreme ends beyond such slots accommodated in the carbon-holder pockets 23 in theside walls of. the lower section.

It will be noted that the fltments just described are located beyond the side edges of the work sheets so that, as one set of work sheets is drawn forward after, another over the writing plate, following the initial properinterleaving of the work sheets of the leading set with the carbon sheets in assembling the device, there is no interference between these work sheets and the carbon sheets,

and the carbon sheets are always in working position relative to their-appointed work sheets. These carbon sheets are of such lengths forward of their points of anchorage that they extend over all the parts of the work sheets on which entries will be made; the writing capacity of .the. carbonsheets .being suflicient to take care or all the car-' bon copies which can be 'made. onthetotal'number of work sheets tobe stored in the casing when finished at the factory of the maker.

Somewhat ahead of the pins 28, the device is provided with a transverse member 3| to hold the leading ends 32a of the leading set 32 of work sheets down-toward the writing plate and so that the apertures in the sheets of such set cannot become accidentally detached from said pins. Here, however, this member 3| is mounted on the top wall of the upper section I0. Said member is merely a transversely rounded metal strip having reduced ends or terminal tabs 3| a sent through holes 2 In of the corner fasteners 2| running along the sides of the top wall l8 of the upper section and through holes in said wall matching these holes 2|a. These holes 2|a are desirably so located that-they are in a line crossing the device perpendicular to the line of travel ofithe work I sheets over the writing plate. Said tabs lla, after being sentthrough the holes 2 la, are bent toward eachothe net-then squeezed tight against the undeesurfaee offsaidtop wall (see Fig. 7). By a construction of this ;kind, not only is the writing platesimpliiid and cheapened, but the least vstrong'pa'rt of the upper section is strengthened andbraced where such strengthening and bracing is most needed; the member 3| acting as an important bracing and stiflening member.

In assembling the device, the pile of zigzag folded work sheets, desirably printed and provided with transverse lines of perforations 33 between forms, is placed in the lower section II and the leading length of the pile is looped as indicated at 24 in Fig. 2. Then, with the forms of the leading set properly interleaved with the carbon sheets 29 and with all these sheets lying on the writing plate 21, and with the carbon sheet holders 38 secured permanently in place as above explained, the writing plate is mounted on the side walls of said lower section II and on the end wall thereof which has the half-round opening 22. The dependent flanges of the writing plate for embracing these walls immovably and solidly set the writing plate in' the intended position; an accompanying result being that this plate acts as a tieplate, rigid in its own main or horizontal plane, to hold the major lengths of the two side walls of the lower section rigid and parallel and to hold the intervening end wall of said section rigidly perpendicular to such two side walls, thereby causing these three casing walls to brace and stiffen each other and in turn to brace and stiffen all the five walls of the lower section.

The form-registering apertures of the work sheets on the writing plate having been engaged I with the stopping and aligning pins 28, the upper section I U is telescoped over the lower section Ii.

. narrow and fairly thick cardboard or wood strips cemented or otherwise suitably fastened in place along the under surface of the top wall of the upper section close up against the side walls iof thatflsection. As indicated in Fig. 2, these j -.strips35 extend from. the delivery end of the casing back to the carbon holder pockets 23.

Finally, the upper and lower'sections of the casing are secured together by a suitable adhesivewater glass for instance--the intention being that these parts It and II shall be held together against separation without destruction. I

The operations described above are intended to be performed at the factory.

In use, the operator makes the desired entries upon the uppermost of the set of forms in place on the writing plate, grasps the end of these sheets by way of the thumb-opening afiorded by the cutout 217' at thedelivery end of the writing plate, advances them one form-length by manual pull, and severs the same'by holding the strips now on the writing plate and snapping the advanced sheets therefrom along a line of per- .forations 33. These operations are continued from time to time as required until all the forms are used up and the casing ready to be destroyed or discarded, whereupon a new container with a similar preloaded supply of work sheets and carbon sheets is put into use.

The term chip board as used herein should be understood to include pressboard or cardboard of various kinds, as well as-other equivalents thereof, and the term "paper material" as used herein should be understood to include chip board or corrugated board or equivalents.

Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
