(01. 40-111) This invention relates generally to perpetual of the invention shown in the accompanying draw desk calendars and similar devices. ings, my invention resides in the novel elements, Perpetual desk calendars have, heretofore, been features of construction and arrangement of , provided with more or less complex automatic parts in cooperative relationship, as hereinafter '5- movements in which a series of cooperating cal more particularly pointed ‘out in the claims. . endar indices and their associated drums progres In the drawings: sively function to indicate successive days upon Figure 1 is a perspective view of the invention; operation of a single control member. The com Fig. 2 is a top plan View of the device shown in plexity of such structures, along with an accom Fig. 1; 10 panying inherent bulkiness, has apparently ef Fig. 3 is a front elevation of the device of Fig. 1; Fig. 4 is a vertical longitudinal section, looking fected the result that devices of this type receive a more or less indifferent reception from the trade in general. from the front, and taken on a line passing through the axis of the device; In the case of those perpetual calendars in - which the various indicating units are independ ently operable, the positioning or placing of the index manipulating members has been so conspic uous as well as so inept as to‘ destroy the sym metrical appearance and consequently, the. aes 20 thetic appeal to the intended purchaser or user of the device. One object of my invention is to produce a perpetual calendar of novel construction, and one in which the above recited detrimental features 25 are obviated. ' It is also an object of this invention to produce a device of this type which is simple and durable in construction, and which ‘can be cheaply manu factured. Another object is to provide a device of this character‘ with a novel arrangement of control members which can be quickly and easily oper ated. A further object is to provide, in such a device, ' means to simultaneously yieldingly position one or more rotative calendar units and ?xedly de— termine the axial positioning of said units. Still another object of this invention is to pro-. vide a novel perpetual ‘calendar, presenting a sym metrical, carefully balanced appearance to the eye, and one having a relatively smooth contour with no exposed awkward moving parts, and a certain part, or parts, of which may be either stamped or cast in metal or even pressed or cast from any one of a number of phenolic condensa tion products, thereby further enhancing its ar tistic as well as utilitarian advantages. With this in mind, other and further attendant advantages will be possible by providing for the accessory utilitarian elements of pen or pencil holding grooves, and the like, in ‘connection with addition ally suggested uses. With these and other objects in View which will readily become apparent from the following de tailed description of an illustrative embodiment Fig. 5 is a vertical transverse sectional view taken on the line 5-5, Fig. 4; 15 Fig. 6 is also a vertical transverse sectional view similar to Fig. 5, taken, however, on the line 6-4, Fig. 4.; and Fig. 7 is an enlarged perspective view of one of the date-indicating indices or drums removed 20 from the casing, with a portion broken away and in section to more clearly disclose its construction. For purposes of convenience and in order to more clearly bring out some of the various advan tages of this invention, it is hereinafter described 25 as substantially consisting of a cast plastic or phe nolic vcondensation product, but it will be under stood that the method of operation of the device and the utility thereof is equally eiifective when cast or pressed from other materials, such for example, as metal. In all of the drawings, corresponding parts have been similarly numbered, the respective numbers being duplicated in order to indicate similar ele ments and in order that they may more clearly indicate the relationships and facilitate the asso ciation of those parts in the cli?‘erent drawings wherein the embodiments herein are speci?cally described. ' The embodiment of the invention herein illus trated comprises a unitary base structure con taining a cylindrical housing for telescopically and rotatably supporting a plurality of date-indi~ eating drums or character wheels juxtaposed in end-to-end relationship. The drums are manu ally operable by means of respective knurled knob members positioned at the extremities of the drum housing. These drums or indices have a distinc tive series of date-indicating characters either formed on or aflixed to their respective periph eries. The date-indicating characters of each series are successively visible through suitable window openings or sight apertures formed in the cylindrical portion of the housing shell. These characters are changed by manipulation of the 55 2 2,110,668 respective knob members. Individual knobs, or the like, are associated with each of the date indi'cating drums to permit independent manipu lation thereof, while spring-actuated detents are utilized for cooperation with notched indentations and grooves of suitable annular con?guration cut in the periphery of the drums‘ in order to more accurately and ?xedly position the index cylinders in their housing. Referring now to the drawings, the invention comprises a unitary base structure It! in which a pen and/or pencil receiving groove I2 is formed, cidental rotation of their immediately associated calendar drums. The windows or sight apertures 3| and 31, formed in the base l0, Figs. 1, 2 and 3, are pro vided for exposing successive printed characters, in the series carried by the drums l6 and I1, progressively into view, upon turning the respec tive knob members l8 and 19. The window open ings or sight apertures 3! and 31 are preferably arranged in a position for the best possible 10 visibility, giving a convenient selective observa and which likewise includes a hollow cylindrical tion of the symbols on the rotating drums. The number of spaced detent-receiving notches on opening i3, Fig. 5, which provides a housing for telescopically supporting the vrotary date-desig nating cylindrical index units generally indicated words or numeral characters on the drums; thus 15 the spacing of the notches on each drum is direct at M and 15, Fig. 4. The right calendar unit designated by numeral l5 comprises a pair of drums l6 and I"! which are ?xedly connected to and each individually oper ated by the knurled knobs l8 and i9, respec tively. The knobs‘ may, most conveniently, be positioned co-axially adjacent each other, as at the right end of the cylindrical housing 13 of base structure l8, Fig. ll. The knob i9 is rigidly se cured either by frictional support or other en gagement to the drum [1, whereas the knob i8 is connected to the drum It by means of an inter mediate axial stud or driving shaft 22, one end of 30 which may be imbedded or threaded into the knob i8, while its other end is secured to the drum it by nut 23, washer 24 and a spacer sleeve 25. The sleeve 25 loosely telescopes the stud 22 and is provided for spacing the drum “5 sufficiently as from the knob 48 to allow the drums l5 and IT to rotate independently. Date-designating wrap pers 26, are tautly drawn over the outside of cylindrical drums 56, l? and are maintained in annular recessed or grooved portions 2'! and 28 49 which are formed on the outer surfaces of the drums it and Ill respectively, substantially as illustrated in connection with the drum l6, Fig. '7. The ends of the wrapper 26 are inserted into the hollow interior of the drum it through an open slot 29, and are securely clamped against the inner surface of the drum 56 by an expander ring or spring clip 30. A spring-pressed detent 32 car ried by the base it, Figs. 4 and 6, cooperates with an annular groove 33 in the drum ll to ?x the axial position of the drum l‘! and indirectly of unit l5 relative to the cylindrical housing l3 of the base it, while still allowing the drums l6 and H to rotate freely about their common axis. In addition, a series of detent-receiving openings 55 3% are formed in the base of the groove 33 and equally spaced, in sequence, corresponding to the spacing of the printed characters on the drum wrapper 26, for successively seating the resilient spring-pressed detent 32. This provides means for accurately ?xing the rotational position of the drum I‘! by equal operative movements of its as sociated knob. A ball detent 35, Figs. 4 and 5, somewhat similarly coacts with complementary notches 36 in the drum it for accurately ?xing the rotational positioning of this drum coincident with the day-by-day movement of successive date-designating characters into alignment with the sight aperture or window 31. The detents 32 and 35 are resiliently biased into engagement 70 with their respective drums by individual springs 33. The amount of biasing action is controlled 75 by set screws 3% carried by the base H3, Figs. 4, 5 and 6. The detents 32 and 35, by suitable ad justment, are particularly adapted to prevent ac each drum corresponds to the number of printed ly proportionate to the spacing of the words or characters thereon. It is obvious that a de?nite alignment of the respective spring-pressed de tents with successive detent-receiving notches is 20 desirable coincident with the progressive posi tioning of the date-designating characters into alignment with their respective windows or aper tures. The progressive seating of the detents by the notches in the drum simultaneously aids in the positioning of the drum and centralizes the date-designating characters relative to the respec~ tive index or symbol exposed in the windows. A plate lit, secured to the base ill by screw members 52, has a series of openings 43 formed therein which are respectively aligned with the spring-pressed detents 32 and 35. The openings 43 permit the adjustment of the detent control screws 39 without necessitating the removal of plate 48. A felt pad 44 may, preferably, be se 35 cured to the plate llil, Figs. Ll, 5 and 6, to prevent scratching of the desk or supporting element upon which the calendar may rest. Inasmuch as the left and right calendar units l4 and I5 embody identical features of construc tion and operate in a correspondingly similar manner, it is believed that the above description relating to the unit i5 will likewise suffice to en able those versed in the related arts to thoroughly understand the construction and operation of unit I4; however, in order to further assist one in understanding the entire invention, similar reference numerals have been employed to desig nate corresponding parts of each unit. Thus 40 there are two center drums which are designated by the numeral l5, and two outer drums which are designated by the numeral ll. It follows that the left calendar unit Hi, see Fig. 4, includes the left end drum l1 and the left center drum l6, 55 whereas the right calendar unit l5 comprises the right center drum l6 and the right end drum IT. The right center drum it of unit i5 is illustrated in Fig. 7. As previously stated an end of the pin detent 32 acts as a position determining device in coop eration with the notches 34 of the drum 5'! for de?nitely fixing the rotative positioning of the drum l1 and preventing any accidental rotation of the drum. At the same time, the body por 65 tion of the pin 32 cooperates with the sides of the annular groove or guide track 33 of the drum I‘! to ?x the axial position of the unit £5. The ball detent 35 cooperates with complementary notches 3% formed or cut in the drum IE to inde pendently determine the position of the drum l6 and prevent its accidental rotation. In the preferred embodiment of the invention, as depicted in Figs. 1, 2 and 3, index characters 70 one to zero, inclusive, are printed on a Wrapper 75 2,110,668 or indicator sheet 26 secured to the drum l6 and are successively visible through the window 31 upon turning of the knob Hi. The drum it of unit M, Fig. 4, may have thereon the numbers one to zero inclusive, also, although, it is prefer able that numbers one to three, inclusive, be used as these alone are necessary. The numbers are successively aligned with the window 3i, Fig. 3, upon manipulating its corresponding knob H3. 10 The characters on the drum 16 of unit it are changed every tenth day and are used for indi cating the ?rst digit of compound numbered days, a blank space being aligned with window 3'! dur ing the ?rst nine days of each month. The char 15 acters on the drum it‘ of unit l 5 are progressively employed to designate dates from the ?rst to the ninth day of the month, following which they are progressively employed to indicate. the second digit of the compound numbers employed to indicate 20 the dates from the tenth to the last day of the month. Thus one drum l6, e. g. that of unit it, is used independently of the other drum e. g. that of unit ill, to indicate the days of the month from the ?rst to the ninth thereof, and both drums it 25 are used in combination to indicate the dates from the tenth to the end of the month. The months of the year, indicated on a wrapper se cured to the drum ll of unit it, are successively visible through the window 3! upon manipulation of the corresponding knob i9. The days of the week which are indicated on a wrapper carried by the drum ll of unit l5 are successively brought into alignment with the window 3i upon manipu lation of the associated knob ill. 35 The invention has been described in speci?c terms, but, the details of structure may be varied Without departing from the spirit of the invention. 'Thus, this invention is not limited to any particu~ lar method of, or product for, forming the base, 40 and, as is obvious to those familiar with the re— lated art, a number of striking and beautiful hues and color combinations are possible and can be produced consistently in the ?nished product by casting the article with any one of a number of phenolic or other condensation products. The result is an enhanced and very striking, as well as a very different and more useful, product than any heretofore possible. I claim: 1.
