Application filed April 2l, 1923,

To all inkom. t may concevoir:

Be it known that l, PrnoY F. SUCH, a subject oit the King ot Great Britain, and a resident of the city, county, and State ot New York, have invented certain new and useful improvements in Shopping Lists, ot which the iollowing is a specilication, reference being had to the accompanying drawing.

My invention relates to that class ot devices intended to serve primarily as reminders that certain articles are to be inspected or purchased during a shopping expedition, a principal object of the invention being to provide a device ot this character which is neat, compact and attractive in appearance, arranged so to exhibit the naines ot a comprehensive listot articles and embodying mea-ns whereby any desired number ot said articles may be selectively designated in such manner as to clearly bringl them to the attention ot the person carrying the device upon an inspection thereof.

A. further object of the invention is to provide a shopping list embodying means by the convenientmanual adjustment ot which any article on the list may be distinctively designated when desired, said means being, however, so arranged as to avoid liability oi accidental movement to or trom such designating position.

A still further object of the invention is to provide a shopping list on which may be printed or otherwise displayed the names ot a relatively large number ot dilterent articles without making the device too large or cumbersome to be conveniently carried in a. iadys hand bag or in the pocket and embodying means readily operable by one hand and from adjacent one edge ot the device to selectively designate such of the articles on the list as may be desired and similarly operable by the same or the other hand and from the same or the. other edge ot the device to withdraw the distinctive designation of any article when desired.

A still further object of my invention is to provide a shopping list ot the character aforesaid which is durable and not liable to become damaged or mutilated in ordinary use, which may be manufactured at a relatively low cost and which may be conveniently employed to perform its intended function.

Serial No. 538,575.

The toregoing, as well as various other objects and novel features of construction and arrangement comprehended by my invention, will more fully appear from the following description of the embodiments thereolE taken in connection with the accompanying drawings forming a part hereof.

ln the said drawings, Figs. l to illustrat-e one embodiment ot my invention, and Figs. 'T to l5 illustrate a second form of my invention.

Referring iirst to the preferred form as illustra-ted in Figs. l to 6 inclusive, Fig. l is a perspective view of the front or side member of the device; Fig. 2 is a similar perspective view of the intermediate member; and Fig. 3 is a perspective view of the back or rear side member, these three views showing the several parts separated but in the relative position in which they are assembled in the completed device.

Figure d is a perspective view of one ol the indicator slides, including the projection by means of which it may be longitudinally moved and the colored portions which are arranged to be displayed through the windows in the front or side member as the slide is moved longitudinally thereunder.

Fig. is an enlarged fragmentary front view or elevation ot the assembled list, the iront member and the intermediate member being partially broken away so as to clearly disclose the details oit the construction and certain oi the indicator slides being' iragmentarily shown or entirely omitted.

Fig. 6 is a transverse sectional view on the line 6 6 ot Fig. 5, looking in the direction of the arrows.

Fig. form ot side member with certain of the indicating means in place; Fig. 8 is a similar view ot' the separator or interniediate member; and Fig. 9 is a perspective View of the rear or opposite side member which in this case is like the side member shown in Fig. T except that it is turned around. These three views. T, 8 and 9, show the several parts separated but in the relative position in which they are assembled in the completed device.

Fig. l() is a perspective view of one ot the indicating tapes with its various adjunctive parts in position thereon.

Fig. ll is an enlarged fragmentary side 7 is a perspective view ot' a modified lll!) elevation of the modified device, one ot the side vmembers and the separator being partially broken away to better show details ot' construction and certain of the indicating tapes being ra-gment-arily shown or beinv entirely omitted.

Fig. 12 is a transverse sectional view on the line lf2-12 of Fig. 11 looking in the direction of the arrows.

Fig. 13 is an elevation et one of the tape ends or tips in assembled position on the end of the tape.

Fig. 14 is a sectional view on the line 14-14 ot' Fig. 13; and Fig. 15 is a plan view ot a tip clamp prior to its being assembled on the tape.

In the embodiment ot' my invention as illustrated in Figs. 1 to 6, the front member 1, the internilediate member Q, and the back or rearmember 3, are preferably all of the same size and rectangular, and are formed ot' any suitable sheet material, such. as celluleid, cardboard or the like. They are relaw tively thin and o't' non-transparent material. The front side member 1 is provided adjacent one ot its side edges 4 with a row of relatively horizontally disposed narrow slots 5, preferably equally spaced from and parallel to veach other. On the face ot the tront member 1 are arranged in two vertical colunms 6 and 7, the names oi the diti'en ent articles. These lists may be grouped in accordance with their different characteristics or their likelihood of being obtained at a single store. Thus, the three articles grouped in the upper part of the left hand column l6, namely, teaf coffee and cocoa. naturally fall into the same category; and similarly, butterf eggs and cheese7 at the top of the right hand column 7 are more or less related and are usually purchased atthe same store. The grouping ot' the different articles in this manner aids materially to the convenience oi the shopping list, particularly if the name o'l' the tirst article in each list be printed or otherwise displayed in a colo-r contrasting with the other articles in that group, but it will be understood that any other manner ot' grouping or displaying the names o't' the articles may be utilizedit desired. At the right of the articles enumerated in column is a, vertical row o't preferably circular pertorations 8 forming windows, one tor each "article in column G, preferably arranged in alinement therewith, and to theV right ot' the articles contained in column 7 is a similar vertical row of spaced perforations 9, one-tor each otl the articles listed in column 7 and in alinement therewith. These perforations 8 and 9 toi-m windows through which the colored portion of the indicator slides may be displayed as will be referred to and explained below. As clearly shown in Figs. 1 and 5, an'article listed in column 6 will be in alinement lwith an article listed in column 7 and the opening or perforation 8 'for the article listed in column 6 will also be in alinement with the perforation S ot' the article listed in column 7.

The intermediate member 2 is preferably provided with t'our vertical rows ot vertical slots 10, 11, l2 and 13. Preferably the distance between the slots in any one row is equa-l to the height of the slot `and thereforeV the slots in the two adjacent rows 10 and 12 are arranged in a staggered relation so that the sheet 2 is not materially weakened and so that the indicator slides adapted to pass therethrough may be arranged in close vertical relation. Thus, a slot in the row 10 will be in transverse alinement with a slot 12 in the third row and a slot 'l1 of the second row will be in transverse alinement with a slot in the .'t'ourth row. rl`hese tour series ol slots 10, 11, 12 and 13 are vpreferably so disposed on the intermediate sheet 2 that they will be in the space between the vertical rows oi' pertorations 8 and 9 ot the l'ront side member 1 when the rectangular margins ot the front member l and intermediate member 2 are in alinement with each other.

Adjacent and to the let't of the vertical row ot' pertorations 10, I preferably provide a thin strip 15 ot soft fabric or leather adhesively secured to the member 2 to proV vide a surface which will aiord some little :triction or resistance to an article slid thereover, and on the rear side of the intermediate member Q and between the vertical rows ot slots 11 and 12 l provide a similar strip 16 ior the same purpose.

ln Fig. el is illustrated a perspective view of one indicator slide 17, ot which there will be in a completed device Vas niiany as there are articles enumerated in a vertical column 6 or 7. This indicator slide 17 is preterably provided at one end with a tab or projection 1S preferably bent up at right angles out of the strip `oi' celluloid or other suitable "iaterial out of which the indicator slide 17 is made. All the indicator slides employed in the device are exactly alike so that this vdescription o't one will sul'iice for all. rlghe projecting tab 18 is arranged to be projected through one of the horizontal slots 5 and it is also adapted `to be insertediirom the 'trout side o'i the intermediate member 2 through one ot the vertical slots, as Yfor instance, one oli the slots 10 ot the iirst vertical row ot slot4 and then passing on the rear side ot the intern'iediate member 2 is projected through the corresponding alined slot v12 of the third vertical row otl slots. By so insertinp, an indicator slidethrough said slots it will be plain that it will rest or bear on the vertical strip 15 on the front Vof the intermediate member 2 and will bearron the vertical strip 16 on the rear side ot the intermediate member 2. The above description of the indicator slide 17 would apply to the top indicator slide shown in Fig. 2. After that indicator slide has been inserted another slide exactly like it would be inserted through a vertical slot 11 and an alined vertical slot 13 and so on throughout the series of slots until there are as many slides 17 as there are articles listed in a vertical column 6 or 7. These slides 17 are so arrangedon the intermediate member 2 that each slide 17 will lie directly under one article listed in column 6, its windows 8, the alined article in column 7 and its window 9. Then the intermediate member 2 has thus been filled with slides 17 it will generally be provided with a flexed or bent portion 14; and the slides 17 will be generally slightly bent, particularly when the slides are of celluloid or other resilient material.

The member 2 is then placed against the rear side of the front member 1 and the tabs or projections 18 are inserted through the parallel elongated slots rEhen the rear or back member 3 is placed against the rear side of the member Q and the three members, 1, 2 and 3, may be permanently secured together in any suitable manner, as by a metallic edge or binding 19.

Now on each indicator slide 17 are arranged three patches of a color contrasting with the color of the material out of which the slide is made. Preferably the slide is white, and the patches 20, 21 and 22 are of red or some otherv contrasting color. The size and arrangement of these spots of color 20, 21 and 22 with respect to the slides and to the windows 8 and 9 will be best understood from Fig. 5, wherein the device is shown as assembled. hen the tab or projection 1S is at the right hand end of its slot 6, no colored port-ion of the indicator slide will be in alinelnent with either perforation 8 or 9 but the spot 21 will be positioned just to the left of the perforation 8. As the slide 17 is now moved to the right, the spot 21 will first be brought into registration with the perforation 8 and that will produce the effect of a round red spot opposite an article listed in column 6. Then so moved the shopper shall have used the indicator to indicate that she wishes to make a purchase of say coffee as shown in the second line of the articles listed in Fig. 5. The next move to the right will bring the spot 21 out of alinement with its window or perforation 8 and will bring the longer spot 2O under its corresponding perforation in column 9. This position is shown in the third line of the list of articles shown in Fig. 5 and indicates that cheese is the article to be purchased. The next movement of the indicator slide to the right will bring the color patch Q0 into registration with the perforation 8 and the long patch or spot 22 will still remain in registration with its perforation 9. Such a position shown in the fourth line of the articles listed in Fig. 5.

Then the indicator slide is .in the last posit-ion above described, the projecting tab 1S will abut against the right hand end of the slot 5.

Thus, by moving the tab 18 from left to right, a red spot may be displayed to the right of either of the alined articles listed in columns t3 and 7, or both articles may be indicated by proper adjustment of the slide 17.

rPhe projections or tabs 1S extend only f slightly above the top or front surface of the sheet 1. They are readily moved longitudinally of the slots 5 by a slight pressure and corresponding movement of a thumb or finger placed thereon and when once adjusted there is no tendency to become displaced or moved from the position to which it is so adjusted. An inspection of Fig. 2 will mal-:e it plain that in weaving the indicator strip back and forth thro-ugh the appropriate slots and over the broken strips 15 and 1G, a slight bend or buckle may be imparted to that portion of the intern'iediate member 2, particularly between the two vertical rows or slots 11 and 12 and when the margins of these three sheets 1, 2 and 3 are tightly bound together in any suitable binding, as for instance, by the metallic binding 19, there will be sufiicient friction upon the indicator slides to prevent any accidental movement of them under ordinary conditions.

In the drawings the space between two adjacent indicator slides is greatly exaggerated. As above stated, the top of one set of vertical slots, e. g., 11 and 13, are in alineinent with the bottoms of the adjacent vertical slots 10 and 12 so that really the adjacent edges of two adjacent indicator slides are substantially in contact with each other. For the sake of clearness, in Figs. 2 and 5, the strips are shown slightly spaced.

In the embodiment of my invention as il- `lustrated in Figs. 7 to 15, the vertical rows of vertical slots 10 and 1 1 are arranged adjacent the left hand vertical edge et of the front member 1 and the third and fourth rows of vertical slots 12 andl are arranged adjacent the right hand edge of the front member 1 and the indicator slides 17 are made of narrow ribbon. In this embodiment of my invention, for selectively designating any .of the different articles whose names are displayed upon the front side of the front sheet 1, manually operable means are provided, comprising said tapes or ribbons 17', one of which is clearly illustrated in Fig. 10. These tapes, which may be of any suitable flexible material, are in width substantially equal to the length of the slots l0 or ll or l2 or 13 so as to readily pass therethrough, but they are slightly longer than twice the width of the front side member l so that when doubled over on themselves'at the center and threaded through vertically adjacent pairs of slots, the ends of each tape and the loop formed at its center will respectively project for a short distance beyond the opposite edges of the front member l.

Each tape is preferably provided at its center with a clip 23 conveniently made of wire, which is bent in such a manner as to securely grip the tape whereby longitudinal movement of the clip with respect to the tape is prevented, this clip preferably comprising an outwardly extending ear 24 which may be readily grasped by the lingers. These clips may be made from a wire ring of suitable size, passed over the tape and then bent substantially in the manner illustrated in Figs. 7 and il so as togrip the tape to provide the ear 2iand also to act as a stop to prevent the tape from being drawn to the right bevond a predetermined point. Any suitable Iorm of clip may be utilized for this purpose. Each tape is preferably provided with bands of a color suitably contrasting with the color of the tape and spaced in definite relation along the body thereof so as to be capable of suitable registration with the` windows of the members when the-tape is assembled therewith. More particularly and considering a tape as extended and shown in Fig. l0 and as divided at its center by the clip 23, a band or area 2O of such contrasting color is disposed on each side of the center at a distance therefrom, a little greateiI than the distance from the windows 8 to the left hand edge of the front member, the width of this band measured along the top being substantially equal to the width of the tape. A second band or patch 2l of color of similar size is disposed more nearly adjacent each end of the tape, this band being outwardly spaced from the bands 2O for a distance equal to the Width of the bands, thus leaving an uncolored area 25 between them. Still more nearly adjacent each end of the tape than the bands 21 is another colored band 22 in width prefe ably twice that of the other band and so spaced on the tape that its inner edge, that is, its edge most nearly adjacent the center of the tape, is disposed at a distance from the corresponding edge of the band 2O Vand is substantially equal to the distance between the centers ofthe windows 7 and 9 measured in a horizontal direction.

While I may apply the bands of contrast- 'ing Vcolor to the tape in any other suitable lmanner, I may,l in certain instances weave Vand show similarly on both sides thereof with the result that when each tape is doubled over at its center and its ends passed respectively through two vertical adjacent pairs of slots, the necessity of twisting the tape upon itself to bring the colored bands on .the outside of each part of the tape is avoided. The several parts hitherto d escribed may be assembled by inserting Athe ends of one of the tapes through each vertieally adjacent pair of slots l0 and llf from the outer side of a member toward its inner side or face, then carrying the ends along the inner face of the member and bringing them out' through the corresponding horizontally alined slots 12 and 13 on the other side of the member in a manner clearly shown in Fig. 7. Preferably, the tape is inserted from the left hand edge el an d carried toward the right when viewed as in Fig. 7, that portion of the tape adjacent the center and which carries the clip being allowed to remain as a loop extending from the slots Iadjacent the left hand edge of the member, for the free ends of the tapes project from the. slots 12, 13 adjacent the right hand-edge. Inthis lembodiment of my invention, the front member l and the rear member 3. are alike and the intern'iediate member 2 is a plain sheet which is inserted between the front and rear members when the outeredges of the three members are brought into alinement close together and bound by the metallic binding 19.

After the tapes have been insert-ed in the several slots in both of the members l and Y 3 or at any other convenient point during the assembly operation, preferably attach suitable tips 2G to the free ends of the tapes, the function of these tips being to prevent theV fraying of the tapes and to guard against the latter being drawn back through the slots or to the left beyond a predetermined point when the device is being operated. These tapes may comprise a wire loop 27 through which the end of the tape is passed and folded back on itself and a T- shaped clamp 26 (see Fig. l5) of sheet metal having laterally extending arms 28 and a longitudinally extending armr29, the former being adapted to be bent about and flattened down on the folded over end of the tape and the latter being adapted top-ass through the loop 27 and bent down over the tape as shown in Figs. 13 and let. As the clamp is preferably so proportioned that when assembled on the tape it will be somewhat wider than the length of the slots, it thus forms a stop to prevent the tape ends from being drawn into the adjacent slots when the tape is pulled to the leftwhile additionally the tips are of a nature to be conveniently grasped by the fingers when drawing the tape to the right.

The tapes having been assembled in the elements and the tips attached, `the side members are then brought together in such a manner that theirI inner faces are in proximity to each other andA with their outer faces oppositely disposed and a separator 2, which may be formed of any suitable sheet material and preferably of the same size and shape as the members, will be disposed between them. The several parts are then firmly permanently7 secured together in any suitable manner, preferably by means of a narrow metallic binding 19 suitably bent over and clamped around the edges of the members l, 2, 3', or, in certain cases, by gluing` the edges together or in any other suitable way so that preferably there will be no adherence between the members and the separator or intermediate member save adjacent the marginal edges thereof. It will be apparent, however, that as the major portions of the inner faces of the members and the outer faces of the separator or inner member are maintained in close proximity, those portions of the tubes lying be-k tween will be frictionally engaged thereby but will be capable of relative transverse movement with respect thereto when either the free ends of the tapes at the right hand` edge of the device or the loops at the left hand edge thereof are pulled and that either the upper or lower length of any tape may be moved in this manner through its slots without disurbing the other sections of that tape.

In making use of a shopping list constructed in a manner last above described, all of the tapes are preferably first brought t0 an initial or non-designating position by holding the device with either side uppermost and drawing the several tapes whose loops are then at the left hand side of the device toward the left as far as they will go, the device is then turned over and all the loops then at the left hand side thereof are also pulled to the left as far as they will go in a similar manner. These operations or manipulations result in bringing an uncolored portion of each tape beneath all four of the windows adjacent to which it passes so that the same will appear therethrough as shown in the windows in the upper horizontal line of Fig.' ll adjacent the words tea, and butter. With all of the tapes thus set in an initial or nondesignating position, if it be desired to designate any article in the left hand column on either side of the list viewed as in Fig. 11, the'tape passing beneath the window to the right of that article is drawn to the right and from the right hand side of the list until the band 21 of contrasting color on that tape registers with that window 8 so as to appear therethrough and thus serve to visibly designate the article, the name of which appears to the left thereof. Obviously, by reason of the spacing of the bands as `hitherto described,

the other window in the .same horizontal col.- umn will continue to show merely the uncolored body 17 of the tape, the parts being now in the position illustrated in the second line of Fig. l1 in which the word coffee is designated by the color in the adjacent window 8, while an uncolored part of the ribbon registers with the window 9 adjacent the word eggs,

Assuming, however. that it be desired to designate an article whose name appears in the right hand side of the list such as cheese in Fig. l1, the adjacent tape is drawn still farther toward the right until the color band 22 shows beneath the window 9 to the right of the name which operation is effective to bring the uncolored space 25 between the bands 2O and 2l under the other window 8 in that horizontal line as shown in the third line from the top in Fig. l1 and then prevent the designation of the article (in this instance cocoa) in the left hand column of that line.

Should it be desired to designate both of the articles listed in any given horizontal. line, for example, flour and bread7 as in the fourth line from the top in Fig. ll, the proper tape is drawn still farther to the right until both colored bands 20 and 22 are in registry with the adjacent windows so as to show therethrough in the manner illustrated thereby, simultaneously calling attention to both of the articles listed in that horizontal line.

After any given designation has served its purpose, the tape may, of course, be wholly or partially returned to its initial position by drawing on the loop at the left hand side of the shopping list by means of the clip 24, either or both parts of the tape being drawn baclr as may be desired, the adherence of the clip to the tape enabling convenient manipulation of the latter for this purpose.

lt will thus be apparent that I have provided a convenient and readily operable shopping list which is capable of containing a relatively large list of articles without being too cumbersone for the purpose for which it is desired, as the names of the articles are arranged in double columns and by a suitable manipulation of the slides shown in Fig. l or the tapes, shown in Fig. 10, any one or more of the articles so listed may be designated when desired. Moreover, by reason of the frictional engagement between the indicator slides o-r the tapes between the elements and the separators, the tapes are prevented from accidental displacement from their initial or adjusted positions, thus assuring that the desired designations will remain on the list until the indicators or tapes are manually operated to remove or alter them.

While I have thus deslbed two forms or l GU.

embodiments ot my invention, it is to be- 2l has been drawn clear and to the lett ot the perforation or Window 8. Similarly, the looped ends ot the ribbon or tape are made ot'such a length that the clamps 2S also serve as stops to prevent the further movement ot the ribbon to the right atter the colored portion 20 has been brought into tall registration With the window or opening 8. In the preferred `torni or embodiment ot .my invention, the engagement ot the tab or projection 18 with the lett hand side ott-he slot 5 is ope itive to limit the movement ot the indicator slide to the left and its similar engagen'ient with the righthand end of the slot operates as a stop to limit the motion oi the strip in the right hand direction.

Having thus described my invention, I claim and desire to protect by Letters Patent ot the United States;
