manner to facilitate the rotation of the drums to expose portions thereof in the window openings.

Still further it is proposed to imprint the drums with a certain calendar material for the purpose of indicating the day of the week, the day of the month, the month of the year, and the year in a manner to permit the drums to be selectively aligned for indicating a predetermined day.

Still further it is proposed to individually mount the drums upon rotatively supported shafts which also carry complementary wheels projected through other openings formed in the front wall of said casing in a manner to facilitate the rotation of the shafts to change the exposed portions of the drums.

Still further it is proposed to provide a means for releasably holding the drums in various fixed positions in which the imprinted matter of the drums will be properly aligned with the window openings. 7

A further object of this invention proposes the provision of a flat edge portion on each of the control wheels which is adapted to be brought into position with the front wall of the casin in a manner to prevent the'projection and exposure of portions of these wheels when not being used to shift the position of the drums.

For further comprehension of the invention, and of the objects and. advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

'Fig Lia a front elevational view of'a new day calendar constructed in accordance with this invention.

Fig. 2 is a vertical sectional view taken substantially on the line 2-2 of Fig. 1.

Fig. 3 is'a horizontal sectional view taken on V the line :4 of Fig. 1.

Fig. 4 is a horizontal sectional view taken on the line H of Fig. 1.

but illustrating a modification of the invention. Fig. 6 is a vertical sectional view taken on the line 66 of Fig. 5.

The new day calendar, according to this'in vention. includes a hollow nickel plated casing I0. shell H having its axis extended substantially horizontal to a surface upon which the device is to be rested. The back of the tubular shell is closed by means of a back wall l2 and a front wall l3 closes the front of the tubular shell H. These walls 12 and I3 are fixedly maintained in position by means of screws M. The front wall i3 is formed with a plurality of window openings i5'in predetermined spaced positions with relation to each other. There is one window opening I5 at a point above the center of the front wall l3 and a plurality of window openings i5 arranged one adjacent each other on a line extending substantially through the center of the front wall. The window openings l5 are preferably four in number.

A tubular rod I6 is extended horizontally to the rear of the window opening l5 and a similar tubular rod I1 is extended horizontally to the rear of the line of window openings I5 These tubular rods l6 and II are adapted to act as supporting axles and are themselves fixedly supportedin brackets l8 provided with openings for receiving the ends of these tubular rods. The brackets l8 extend rearwards and are provided with pairs of bosses l6 through which set screws [9 are adapted to pass. These set screws l9 also threadedly engage the back wall l2 of the hollow casing for fixedly attaching the brackets l8 to this back wall.

The tubular r'od l6 carries a drum 2!! in an aligned position with the window opening I 5*.

The drum 20 is imprinted upon its face with gressively rotated. The drum 2! isv fixed to a tubular shaft 2| which is rotatively positioned on the rod l6. One end of thetubular shaft 2| is provided with a control wheel 22 which extends through an opening 23 formed in the front wall ii of the casing. The wheel 22 is provided witha knurled periphery which'permits the same drum 20,.

Fig. 5 ma view similar to a portion of Fig. v1 5 There is a drum 24 provided for each of This casing is characterized by a tubular" follows 2, 3-blank. The next drum to the right is imprinted upon its face with the numbers from zero to 9, and the last drum to the right is imprinted with twelve year numbers arranged in chronological order. Each of the drums 24 is fixedly attached to a tubular shaft 25 which rotatively engages the tubular rod I! which acts as a support therefor. The tubular shafts 25 have certain projected portions upon which control wheels 26 are fixedly mounted. These control wheels 26 are projected through complementary openings 21 formed to the right and left of the line of window openings l5 and in the front wall I3 of the casing. It is thus possible to selectively rotate the wheels 25 to retate their complementary shafts 25 and drums 24 carried by these shafts to align different portions of the drums with the window openings IS".

A means is provided for releasably holding the drums in various fixed positions in which the calendar material imprinted thereon will be properly aligned with the window openings I5 and HP. This means is alike for all the drums 20 and 24 and is characterized by a ratchet wheel 28 each of which is provided with a plurality of. teeth. The teeth formed in these ratchet wheels correspond in number to the number of impressions made on the faces of their respective drums. That is, the drum 2!! which is used to indicate the day of the week has seven impressions and its respective ratchet wheel is preferably provided with seven teeth.. The drum ,2! for indicating the month of the year is provided with twelve impressions and its respective ratchet wheel 28 has twelve teeth. Each of the drums 24 has its respective ratchet wheel formed in a similar manner.

A' pawl 29 is extended rearwards from the ratchet wheels 28 and is pivotally supported upon a bracket 30 which is mounted upon the rear wall I 2 of the casing Each of the brackets 30 is provided with bosses through which'set screws 3| are engaged. These set screws 3| also threadedly engage the rear wall H of the casing v for fixedly maintaining the brackets in position thereon. Each of the pawls 29 has a hook portion 29 which engages the teeth of its respective ratchet wheel 28.

A leaf spring 32 is fixedly mounted upon the top of the bracket 30 by means of a screw 33. The free end of the leaf spring 32 bears against the free end of the pawl 29 for urging the pawl into a position in which its hook portion 29 will be engaged with the teeth of its respective ratchet wheel28. The ratchet teeth andthe hook portions 129 are-arranged in such a manner as to limit rotation of the drums 24 in a" clockwise direction and restrain movement in the opposite direction. I

of. this form of the device is as The operation After the newtdayicalendar has-been properly assembled it is possible to indicate any'predetermined day of the'year by rotating the proper wheels or to cause the respective drums 20 or -24 to" rotate therewith and bring the proper predetermined calendar material in position with engage the teeth of the ratchet wheels 28 will slip over these teeth permitting a free rotation in a clockwise direction and will also limit rotation in the opposite direction and act to hold the I drums in-a position in which the respective calendar material will be properly aligned with the window openings.

According to the modification'of the invention shown in Figs. 5 and 6 the construction of the new day calendar is similar to that previously described except for the provision of a means are attached. In this form of the invention each of the wheels 26' is formed with a flat edge portlon 25' which when aligned with the face of the front wall l3 of the casing prevents the wheel from having a portion projected beyond this face. Means is provided for locking the wheels 16' to their respective shafts when turned in a clockflat side to be aligned with the face of the casing irrespective of the position of its drum. This means comprises a clutch characterized by a pair of oppositely disposed balls 35 located within cutouts 36 formed in the inside surface of the wheels 25' and adjacent their respective shafts.

The openings 36 are of a particular nature and have an enlarged end 36 and a reduced end 36'. When the wheels 26' are rotated in a clockwise direction the balls 35 will be moved to engage within the reduced portions 36" of the openings and act to lock the wheels 26' to their respective shafts to cause the same to be turned. However, when an attempt is made to rotate the wheels 26' in an anti-clockwise direction the balls 35 will be positioned within the enlarged portions 36' of'the openin s 36 to permit the wheels 26' shafts. When the wheels 26' have their flat edge portions 26* aligned with the face of the casing as shown in Fig. 6, and to start rotation thereof in a clockwise direction, it is merely necessary to press inwards upon the top of this flat portion which will cause the bottom to be exposed tobe conveniently gripped in ones fingers.
