ASS IGNOR TO MALVIN LIGHTER IIlTC A CORPORATION OF NEW YORK MECHANICAL MEMORANDUM AND METHOD OF MAKING THE SAME Application filed August 13, 1928. Serial No. 299,274.

My invention relates to structural improve-- ments in mechanical memorandums of the kind just mentioned, for improving the efliciency thereof, by giving to the construction an arrangement of the various parts certain points of mechanical advantage.

My invention further relates to an improved method for shaping certain of the parts and for fitting them into position, with a minimum expenditure of time and labor.

Further purposes and objects of my invention are brought out in the descriptive matter set forth below.

drawings forming a part of this specification, and in which like reference characters indicate like parts throughout the several figures.

Figure 1 is a fragmentary plan of one of the blanks used in making my improved mechanical memorandum, and it is cut from sheet material, preferably card-board or the like. I

Figure 2 is a fragmentary plan of another blank used in the construction of my device,

' and having the form of a serrated strip made of sheet material, such as card-board.

Figure 3 is a fragmentary plan of still another blank having the form of a serrated strip made of sheet material such as cardboard, and used in my construction.

Figure 4 is a fragmentary plan showing the blank appearing in Figure 1, and a pair of strips of the kind shown in Figure 2, as assembled and fitted together during the manufacture of my device.

Figure 5 is a fragmentary plan indicating a further step in manufacture, the two strips just mentioned having been cut into small pieces, each having the form of a slide.

Figure (5 is a plan view of the finished art cle, certain parts being broken away.

l igure '1' is a section on the line 77 of Figure 6, looking in the direction indicated by thearrows.

A blank 7, made of sheet material such as card-board, paste board, celluloid, thin leather or leatheroid, tough paper or the like, is cut out and rorined as indicated more particulariy in Figure l. I

lhe blank '2 is provided with flanges 8 and 9, and with end naps l0 and 11, these all being preferably integral as shown.

'ine blank is i'urther provided with score lines l2, l2, 13, 13, and is adapted to be folded or bent, upon these score lines.

The blank is further provided with two rows of circular openings 14; and 15, coinciding in general direction with the score lines 12, 12, and is further provided with two rows of openings, 16, 17, carried by the flanges 8 and 9, and having the form of arcuate slots. The purpose or the openings 14, 15, 16, and 17,

t 1 is explained below. Relerence is made to the accompanying In connection with the blank 71 use two smaller blanks having the form of strips 18 and 19, of the kind shown in Figures 2 and 8, respectively,'and made of sheet material, in this instance card-board. During the manufacture of my device these twostrips are each connected with and fitted upon the blank 7, as indicated in Figure 1, but in the finished article the two strips no longer appear as strips, they having been cut into pieces each having the form of a slide, as may be understood by contrasting Figure t with Figures 5 and 6. l p The strip 18 is provided with tongues 20, 21 and 22 integral with it, the tongues 20 being somewhat longer than the tongues 21, and the tongues 22 being of substantially the same length as the tongues 21.

The strip 19 is provided with tongues 23 exactly like the tongues 22, and is further provided with tongues 24, having the same form as the tongues 21 and being of the same length thereor".

in practice the two strips 18 and 19 are each laid upon the blank 7, and for the time being secured thereto as above described. For this purpose the tongues 20 and 21 are tucked through the openin s 16, having the form of slots, and the tongues 22 are tucked through the circular openings 1 Similarly the tongues 23 are tucked through the circular openings 15, and the tongues 2a are tuck-ct through the slots 17.

This leaves the blank 7 with the strips and 19 in the condition indicated in Figur Next the two strips 18 and 19 are each cut crosswise, so as to form from it a numberot separate pieces 25 and 26, each having the form of a slide, the slides being arrange 1 in two rowsparallel with each otner, as indicated in Figure 5.

The step of cutting the strips crosswise i preferably effected by scans of cutting machinery adapted for the purpose, but may be done by hand. The main requirement in this all be severe respect is that each strip s a sufiicient number of places to co into slides, care being exercised to make cuts in the right places in or ler to ren ler slides of proper form.

The next step in manufacture to b the flanges 8 and J upon the score ll 12; and this done, to next bend over fhips 10 and ll, so as to cause them to overlap the adjacent POTLTO:.1S.OID the flanges 8 and 9.

A'guide sheet 2. made of card-board. or other appropriate sheet material, is next 1 l in position, so that i n To LS ends overlap the cent or inner portions of the end flaps l0 and 11, the sides of the guide sheet overlapping the exposed portions of the tonges or slides 25 and 26. Thus the two edges of guide sheet 27 slightly overlap and en directly the adjacent portions of the 8 and 9.

The guide sheet 27 is provided wit cirlar holes 28, so located that with the sheet in position these openings are in registry with the tongues of the slides 22, if this instance four in number, as indicated in the upper left-hand corner of Figure 6.

Up to this in the manufacture there s no occasion for the use of r adhesive any special mechanism, aside irom the respective terms given to the vari parts, and the connection or" the various parts, as thus fitted together.

The next step of manuitact the other parts, as partially relation inst described, face sheet is other approp vided with circular holes 30 positioned to re v above described with retere so to the holes 4.

sheet 1 and thus to register with the tongues of the adjacent slides.

The face sheet 29 has a pair of oppositely disposed edge portions 31 and 32, integral with it. These edge portions 31 and 32, shown more particularl' in Figure 7, are glued or pasted firmly down upon the underlying portions or the flanges 8 and 9, and are thus firmly secu ed in position. 7

The only pasting or gluin required in my device or in the manufacture thereof, is between these edge portions 31 and 32 and the ent underlying portions of the flanges No casting or gluing is necessary for one "uide sheet 2?, it being held in posiw itting into and among the other parts. l ce sheet 29 is provided with graphic shown, such as the words Butter, Tea, Tomatoes, etc, represent various items concerning which the ually a housewife, seeks to be These legends are so located as in immediate association with the varil the slides are so arranged and other parts that, by drawing ber oi? the slides, appropriate indications can be made.

Tt will be noted from Figures 2 and 6 that some of tslides are provided with longer tongues th 1 others, the slides with the long tongues b PlOTlClQLl with legencs 1 and 2. These par icular slides are used as indicated in the upper left-hand corn r of Figure 6 By pulling either of the slides outwardly the appropriate legend 1 or 2 is exposed to view through the holes 28 and 30. The face sheet has lLS upper left-hand corner, accord ire 6, a number of legends wuer 1, Yeast- 2; Bacon 1, Ham 1 Lentils 2; Bread 1, Crullers 2. oned legends are so arranged van. ms represented by the legends can be indicated by the positions into which the slides are drawn out.

The various upper slides shown each has only two normal positions ;,one being when the slide is pushed inwardly to the limit of its travel, so as to register no indication, the other being when the slide is drawn outwardly to the limit or its travel, in which event it makes onl single indication, this indication being associated with a single one of the various legends above mentioned.

lily device being new practically completed, the last step is to 1 eke a hole 33 through it at its top, to facilitate hanging it upon a nail or a hook. T 1 ole can be made by a punch applied to the finished article; or may, if desired, be produced by perforating the various cardboard members before they are assembled.

The operation of my device may be understood from the foregoing description. The device as a whole serves the purpose of a mechanical memorandum, and with the slides once arranged to make appropriate indications of the items concerning which the operator desires to be reminded, it will stay in that position for any length of time. I

The operator, in using the mechanical memorandum, first pushes all of the slides inwardly, the net result being that for the moment the memorandum registers no indications. Next the various slides, or such of them as are required, are drawn out as above described, so as to make the appropriate indication.

I do not limit myself to the particular steps of the method above described,or to the precise mechanism illustrated and described, the scope of my invention being commensurate with my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:
