Referring to the drawings in detail, a casing I including a rear wall 2 and a front wall 3 supports and houses the clock mechanism for rotating the hour and minute hands 4 and 5, respectively. This mechanism is the conventional electric clock mechanism and is shown more fully and described in my aforesaid application. The mechanism includes a magnetic coil 6 which is connected to the motor (not shown). When the coil is energized, its Acore I transmits impulses to armature members 8 connected thereto which impulses are transmitted byY said armature members to a laminated'disc member -S positioned between them whereby said disc member is ro rated. Disc member 9 is fastened to a shaft I0 carrying a worm l I which is operatively connectked by a gear I2 to ashaft I3 disposed rat'right f Cil angles to shaft iii. Shaft I3 carries a worm I4 which meshes with a gear I5 on a shaft I6 disposed at right angles to shaft I3. Shaft I6 caru ries a Worm i7 meshing with a gear is fastened to a shaft or arbor i9 for driving the vhour and minute hands. The hour hand 4 is fastened to a bushing or sleeve 20 loosely mounted on the arbor i9 adjacent its outer end, and minute hand 5 is secured to a bushing 2| fastened to the outer end of the arbor.
'A disc member or plate 22 is secured to the exterior of the front wall 3 of the casing Vby screws (not shown). Suitably fastened to the outer surface of the front Wall 3 is the clock face or dial 2li. interposed between the inner periphery of the outer disc and the clock vdial is a'ring member Z. The disc member, ring member and clock dial are disposed in the same plane. The ring member '25 is divided into twenty-four sections Y25 representing the twenty-four hours of the day and this ring member moves only onetWenty-fourth as fast as the minute hand 5 of the clock dial.
The sections of the ring member are marked to indicate the hours of the day. The hour` of midday or noon is marked with the representation of the sun as indicated at 25x and the hour of midnight is marked with the representation of the moon as indicated at 25". Reading antilclockwise from noon as viewed in Fig. l, the sections 25 representing the hours of one oclock p. In. :to four oclock p. m. inclusive are marked with the numerals L IL IIL and IIIL and the sections representing the hours from five oclock p. mj to eleven oclock p. m. inclusive 'are marked by the roman numerals V to XI inelusive, midnight being represented by the representation of the moon. The sections representing the hours'from twelve oclock midnight to four oclock a. in. are marked with the numerals 1, IL III and III'L The sections representing the hours from fiveoclock a. m. to eleven oclock a. m. are marked with roman numerals V to XF inclusive, said sections with the eX- ception of the section representing the hour Iof ten oclock a. m. and p. m. being divided into outer and inner sections by a line running -across the center of said sections, with the roman nin merals appearing above and below the lines inr reversed positionsas seen in Fig; l. The section-2E' representing the p. m. hours are also divided into outer and inner sections thesanre as a. m. The
p. m. numerals are whiteon blackb'ackground and the a. m. numerals are black on white background forV night and day, respectively.
Disc member 22 is divided into twenty-four sections or segments 22 by radial lines 22:1: in line with the sections 25' and form continuations thereof. The segments bear the names or initials of the countries, principal cities and islands of the world located in the same time belt or zone, for example, U. S. S. R., Kiev etc. The segments bear only a portion of such names as it is believed that this is sufficient for illustration purposes.
The mechanism for rotating the ring member 25 at the -calculated speed is fully disclosed in my aforesaid copending application and only a part of same is shown herein including an internal gear member disposed between the ring member 25 and the front Wall 3 of the casing and is fastened by bolts -21. This gear member comprises an outer ring member with teeth 28 on its inner periphery and an inner ring member with teeth `29 on its inner periphery. A shaft 3B is journaled in the walls of the casing parallel to the arbor i9 and is divided into a front shaft section 3| rotatably mounted in the front wall 3 and a rear shaft section 32 slidably and rotatably mounted in the rear wall of the casing and in the wall of a bracket 33 secured to the rear wall. The inner end of the shaft section 32 has a keyway coacting with a key on a coupling member v35 fastened on front section 3l whereby the c sections 3l and 32 are connected for rotation in unison. Loose on shaft section 32 is a gear `36 mesh-ing with gear 31 on shaft I9. Gear 36 has a, wedge-shaped socket portion 38 supported by a U-shaped plate or support 39 secured in the casing. Fastened to the shaft section 32 adjacent the gear 36 is a clutch member 40 movable into and out of engagement with said socket portion whereby said gear 36 is made fast and loose respectively on said shaft section 32. A coil spring 4l urges the clutch member 4!! into engagement with the socket portion 38. A pinion or gear 42 is fastened to the front shaft section 3l adjacent the front of said shaft section, and loosely mounted on said shaft section in front of the gear 42 is a gear 43 having an elongated hub portion extending toward the outer end of the shaft section. Fastened to the front face of the gear 43 is a large cam member 44 and in front of said cam member 44 is another smaller cam member 46 fastened to the larger cam member. The gear 43 and the cam members rotate in unison loosely around the shaft section 3l inside the casing. The cam members are adapted to actuate a lever 41 which is operatively connected to the internal gear member for moving said gear member only one-twenty-fourth as fast as the minute hand 5.
The present invention is concerned with mechanism for adjusting the hands of the clock and the other shafts from the front of the clock independently of the mechanism for moving said hands and shafts. For this purpose, the bushing members 2c and 2l supporting the hour and minute hands respectively are formed with an aligned socket portion 48 having opposed slots 49 on its outer edge.
'Ihe front shaft section 3l of shaft 30 has a socket portion 5U extending through the clock face 24 which socket has opposed slots 5| in its outer edge. The clutch member is formed with an annular groove 52 and a bracket 53 on the plate 39 adjacent the rear wa'll 2 of the casing has a bifurcated end portion for supporting a pin 54 and pivotally mounted on this pin is a lever member 55 having a bifurcated end 56 engaging the grooved portion of the clutch member 40. The other end of the lever member is pivotally connected to one end of a rod member 51 which extends to the front wall of the casing. The other end of rod 51 has a socket portion 58 which slides in a sleeve member 59 supported in aligned openings in the front wall of the casing and the clock face. Secured in the socket portion 58 of the rod by a bolt 6U is a bushing member 6|. The bushing member carries a protruding pin 62 and has opposed slots 63 formed in its outer edge. The sleeve member 59 is formed With a bayonet slot 64 adapted to receive the pin 62 and hold the socket portion and bushing meinber in inward position.
Shaft I0 has a tubular extension 65 similar to the tubular extension 53 of front section 3i of shaft 30 extending through the clock face and provided with opposed slots 66.
For adjusting the parts of the clock, a key member 61 illustrated in Fig. 8 is provided. This key has a cylindrical handle portion 68 and a reduced cylindrical portion 65 on said handle and a cross pin 10. For adjusting the hands of the clock, the cylindrical extension 69 is inserted into the socket portion 48 with the cross pin 10 positioned in the opposed slots 49. By turning the key member the bushing members 2U and 2| and shaft are turned thereby turning the hands for necessary adjustment.
To adjust the ring member 25, the clutch member 40 must be moved out of engagement with the socket portion 38 of gear 36. This is done by inserting the key member into the bushing member 6I with its cross pin in the opposed slots 63 of said bushing member. The bushing member is pushed inwardly by the key member which moves the rod member 51 inwardly thereby rocking the lever member 55 on its pivot pin 54 which will move its bifurcated end 56 outwardly carrying the clutch member 46 along With it away from the gear 36 thereby disconnecting said members. When the bushing member 6l is moved inwardly its pin 62 Will move into the bayonet slot and thus hold the lever 55 in rocked position. When the clutch member is thus disconnected, the key member may be inserted into the slotted tubular extension 5G on shaft section 32 and the shaft turned as desired.
For adjusting shaft H3, the key member is inserted into the tubular extension 65 on said shaft and the extension turned for turning the shaft.
