39 designates a pin which is carried by the bar 26 and which engages with the lower portion of the pawl 30 to lift the same when the arm 26 is lifted, and 40 designates a pivoted stop situated at a suitable point above the pawl 30 in order to prevent the improper upward movement thereof, said stop 40 being suitably rotated on its pivot by means of a pin 41 also carried by the bar 26 and which is in en agement with an ofiset on the stop 40, in orcl er to lift the end of the latter and to remove it out of the path of the pawl 30 at the proper time.

42 designates an adjustable weight on the ofi'set of the stop 40 which controls the speed of the return movement of the said stop 40 after it has been rotated as above described and then released.

43 designates a spring, one end of which is in suitable connection with a stationary point. and the oppositeend of which is connected with the lever 32 which tends to draw the same into such position as to return the owl 30 to its normal position, as illustrated in full lines in Fig. 11 and parts in dotted lines in Fig. 9. 4:4 designates another sprin which is connected with the pawl 30 itself and also a suitable stationary point, which also tends to draw down or return the pawl 30 to its proper position to engage one of the arms 45 as illustrated in dotted lines in Fig. 9.

.45 designates arms which are mounted on the governor shaft 46 which is suitably supported, said arms being adapted atthe proper time to be engaged by the pawl 30 to hold the same and prevent rotation thereof and so the governor shaft 46. Also carried on the governor shaft 46 is a disk 47 having the pins 48 therern. said pins being in the path of movement of the are 28 of the lever 27, whereby it will be understood. when the. arc lever 27 elevated by the arm '26 being: 'aised by the lever 2:? due to engagement of the latter with one of the cams on the star wheel 24-. that the pawl 30 is elevated and so released from its enqnqemcut from one of the arms 45, meanwhile the arm lever 27 moves upwardly so that the an: 93 is placed in the path of movement of the p ns 49, llnieh will contact therewith and so be held against rotation until the end of the cam on the star wheel .24 with which the lever 23 is in engagement is reached, immediately upon l Y one which the lever 25 falls, lowerin the bar 26 and. the arc lever 27, whereby t 1e are 28 is removed from engagement with one of the pins 48 and the (llSk 47 is released and with it the governor shaft 46 which is free to retatc. The actuation of the shaft 46 is accomplished by mechanism as will be hereinafter described.

It will be understood that when the bar 26 is raised the pawl 30 is raised, rotating the lever 32 on its pivot and moving the lever 33 from its position seen in Figs. 9 and 10 to the left in said figures and so causing the notch 35 to be engaged by the tooth 37 thus holding the lever 33 and so the pawl 30 in elevated position, the end of the stop l0 being removed from the path of movement of the pawl 30 by the upward movement of the bar 26 as previously stated.

49 designates a plate shaft which is suitably supported and is in suitable connection with the governor shaft 46 by means of a train of gears, whereby it will be understood that when the governor shaft 46 is permitted to rot-ate it will actuate the plate shaft 4.9 to rotate the same.

50 designates a round plate mounted on the plate shaft 49, which plate is provided with a cut-away portion or notch 51 in which is normally seated the end of a dog 52 pivotally mounted. and it will be understood that when the plate 50 is rotated with the shaft 49, the dog 52 will be elevated out of the notch 51 and will cause an extension 53 thereon to engage the notch on the lever 33 at the same time lifting the latter and releasing the notch from engagement with the tooth 37 but as the dog is held in elevated position while it contacts with the edge of the rotating plate 50, the pawl 30 will be held in its elevated position, that is, until the dog 52 is returned to the notch 51 immediately upon which the springs 43 and ii act to return the pawl 30 to engage with one of the arms 45 on the shaft 46 and so stop the rotation of said shaft.

From the above it will be understood that I have provided means for locking the governor shaft against rotation and for releas ing the same automatically at predetermined times, the parts being actuated by the clock mechanism, so that. as the hands of the clock rotate. the govemor shaft will be actuated at the proper time and for the proper amount of time all of which. as neviously stated, being controlled by the clock mech- "Hi3!"- i will now describe the indicator and the connections between the. some and a governor shaft in order that the indicator will in! intermittently and autonmticallv controlled hv the clock mechanism.

Each plate or link of the inclicator represents, in the present instance, fifteen. minutes of time, this being more 'fthis norement-"resultsand to more the which-is in suitable connection with {thandle G 6 forrotating the same, said pin fifiihavand further-in order to control the rotation understood from Figs. 1 and-ft, and referring to the latter it will be seen that the next 11 :15, the next. 11:30. the neat 119:5 and then 1:2 :00 and so on, and as will be seen from Fig. 1., that twenty-four hours are always represented by the links in the open ing. that is, from twelve o'clock midnightto twelve oclock midnight and that. the chain is nrorided with two hundred and days time.

It will he understood that the indicator is adapted to be intermittently actuated and in such a manner that at each movement the distance of one divisional line is moved. that is to say, referring to Fig. l, that where the link with 11:00 thereon appears. over the divisional line to the left of the figure a. rer 'thesnid line and ingflinksgwill be moved in'e,*and it is-nceessary tii'atqthe chain in order that e-vdis tn nc'e b lap y s. c'hainjorindicator at the )roper time with 70 respect tojthe' movenient oi the hands of the clock 1.; -To accomplish this result I have niounted'tlie drumlfi'l' upon a shaft 60 shit ably supported and WllICh has one end of asprin I61 connected therewitm the opposite on of which is eonnectedwith a barrel (32 which is provided with a gear G3which meshes witha gear 64 carried on a pin 65 'ingfsnitably connected therewith a ratchet li'i, 'thelteeth of,which engage a pawl 68, to prerent impropera'etnrn movement of the "pin '65, it being 'nnderstood that by the proper rotation-hf the'handle'66 the pin (lo-is: rotated whichthus rotates thege'a'r-fi andsorotates' the barrel 62 in order to wind up the spring" 61 which will thus impart motion through the shaft 60 at the proper 'ti1ne,"to the drain 57, in order to rotate the same and so move theindicator 54.

Inorder to provide an even rotation to the drum 57 and thus to the indicator 54 of the drum 57, starting and Stopping the same at the proper'time, I provide a beveled gear 69 which meshes withabeveled gear 70 on said drum-5T, said'bevele'dgear 69 being mounted on a shaft 71 which'carries a gear 7 -2- which is in suitable connection with a train of gears between it and the governor shaft 46.

In the present instance I have shown the gear 72 meshing with the ear 73 which is in mesh with the gear 74 w \ich meshes with gear 75, said gear 75 meshing with the large gear 76, which gear meshes with a gear 77 which is carried on the plate shaft 49. Also meshing with the gear 76 is a small gear 78 carried by agear 7 9 which meshes with a small gear 80 carried by a gear 81 which meshes with a small gear 82 carried by the gear 83- which meshes with the gear 84: which is mounted on the governor shaft 46. 85 designates a governonwhich may be of any suitable style or arrmigement and which is mounted on said shaft 46. From this it will be understood that while the governor shaft 46 is prevented from rotation by means of the mechanism previously described no motion is imparted to the train of gears nor to the indicator 54., As there is a steady tension on the train of gears due to the STJIll'HI 61, the drum 5? will immediately he rotated when the pawl 30 releasii the govern r haft 4-6 and will continue t rota e until the pawl 30 again locks in one that the indicator will be moved so that the link with the numeral 15 thereon will be governor shaft 46, whereby it will be seen that intermittentmotion, every fifteen minutes, in the present in ance, will. he impart.- edv to the indicator 5% and. the some will be moved, the distance of one division on the chart at each actuation thereof, in order to properly indicate the t me at one of the division hues corresponding to the tune on the clock.

It will be understood that one revolution of the minute shaft 3 represents an hour and that the four cams thereon represent the movement or the actuation of the indicator four times every hour or every fifteen mmutes.

From the above it will be seen that I provide the indicator with means for actuating the same and connections between the indicator and-the governor shaft 1n order that the said indicator will be actuated at the proper time in order to move the links carrying the numerals into the proper position to indicate the time of the places on the table or chart beneath the same or in line therewith corresponding to the local tin 1e.

8G designates a winding stem which 15 1n suitable connection with the springs 12 of the clock, said stem as best understood from Fig. 4 extending completely across the machine in order that the clock may be wound from the rear.

I desire further to call attention to the construction of the idlers 3S and of the (ll-1111157, in which the portion of the same engaged by the indicator or chain being octagonal and being provided w1th grooves or recesses 87, at suitable pointstherearound, in order to receive the extending portions 88 of the indicator 54, which in portions, in the present instance, form the connections between the various links, it being understood that by this means the indicator is actuated by the drum 5? and is always maintained in proper position as it passes around the various idlers.

It will be noted more particularly from Fig. 7 that the portions 88. extend equally each side of the links or, in other words, each link extends centrally from its joint.

In the construction shown in Fig. 16, I have shown a preferred form or one manner in which I can am'ange the plates, forming the indicator. in order to show the difference thereon between the night and day time.

Referring to Fig. I it will be understood that the opening 55 permits a full day to appear on the indicator and that the indicator is there placed in position to show from twclrc o'clock midnight to twelve oclock n'iidnight. In order to have a uniformitv' of arrangcmcut of the plaics I have provided that from six o'clock in thc mornng to six oclock at night shall be considered day hours and that from six oclock at night to six oclock in the morning shall be considered night hours. The plates havmg the time indications fr m six oclock in the morning to six oclock at night I have shown with a white background and the others from six oclock at night to six oclock in thc morning I have shown with a blue backgromid so that it will be very easy to read the hour. I have also arranged that the hour numerals are in red and the minute numerals in black in order to make a clear distinction between the same and so that the time canbe easily determined.

The operation of the device is as follows: The clock having been wound and the spring 61 having been properly wound by the actuation of the handle 66 the parts are ready for movement, it being understood that the position of the indicator (and the links composing the same) is properly placed or adjusted in order to correspond to the local time indicated on the clock, for example, rcferring to Fig. 1, it will be understood that if it is seven oclock a. m. by the local Philadelphia clock 1 the link having seven thereon will be on the divisional line of the chart on which, say Philadel )hia is situated, when the times at the ot 1er places will be automatically and properly indicated by the numerals 011 the links of the indicator, for example, if it is seven oclock a. m. in Philadelphia and it is desired to know the time at London by following up the line on which London is indicated it will be seen that it is twelve oclock noon there and the time of any other place on the chart will alsodbe correctly and synchronously indicate.

Itwill be understood that the governor shaft -16 is held against rotation by the pawl 30, the arts being in the position seen in Fig. 9 and that as the clock 1 continues in its movement the minute hand shaft 3 is rotated, carrying with it the star wheel and causing one of the cams thereof to elevate the lever 25 which raises the bar 26 elevating the pawl 30 to release the arms 45, atthe same time moves the end of the stop 40 from its position to prevent the upward movement. of the pawl 30, and, at the same time, forcing over the lever 33 by reason of its connection with the lever 32 and causing the notch 35 to be engaged by the tooth 37 3 so that the lever 33, the lever 32 and pawl 30 will be held in elevated position with the latter out of the path of movement of. the arms -15. hen the end of one of the cams is reached the bar 26 falls and will be drawn down by the springs connected therewith, immediately upon which the governor f shaft 46 is released and is permitted to r0- tato by reason of the tension of the spring 61 on the train of gears in connection with i the governor shaft and the drum 5? is im- I' mediatcly caused to rotate and move the indicator 54 so that a link is moved from one divisional line to the next, at which time the mechanism operates to stop the further movement of the indicator for a certain time when it is again actuated as previously described.

It will be understood that at the some time the governor shaft 46 is rotated the plate shaft 49 will also be rotated by reason of the train of gearing between the same. This will carry with it the plate 50 and will elevate the dog 52 causing the extension 53 on the dog to engage with the notch 34 on the lever 32 and at the same time elevating the said lever 33 and removing the notch from engagement with the tooth 37. The pawl 30 will be held, however, in elevated position until a complete revolution of the plate 50 occurs, since the dog being in enga emcnt with the edge of said plate 'lll be hel d in elevated position, until it again enters the recess 51, in said plate, immediately upon which the lever 33 is released and permits the pawl 30 to fall to enga e again with one of the arms 45 on the governor shaft 46 and thus sto ping rotation thereof. By this means it will be seen that the indicator is moved every fifteen minutes at the pro er time with respect to the movement 0 the hands of the clock and is controlled by the clock mcchanisn'i while the actuation thereof occurs through the medium of the spring motor.

As previously stated, it may be necessary to set the clock from the back and applicant has provided the structure more particularly seen in Fig. 14 for this purpose, since it would be impossible in some instances to have access to the front or face of the clock. By grasping the handle 3* on the shaft 3 the said shaft can be moved in the direction indicated by the arrow in Fig. 14 a suitable distance to release the pins 14 from engagement with the openings in the disk 15 at. which time it will be seen that the shaft 3 is disengaged from the hollow shaft 10 which is in suitabl connection with the springs of the clock, and the said shaft 3 can be independcntlv rotated by hand to set the clock. As the shaft is moved over, the groove 21 therein is brought into line with the pin 22 which immediately enters the same and prevents rotation of the shaft. 3 until the rod is removed from said groove 21 at which time the pins 14 will again engage with three of the openings in the disk 15 so that the shaft 3 will again be locked with respect to the hollow shaft 10 and so to the clock mechanism and will be actuated thereby.

From the above it will be seen that 1 cm- I ploy an ordinary clock face adjacent to the chart and show on its dial twelve hours. which being of u ual construction can easily be read by the observer.

I also desire to call attention to the use i of a divisional table, plan or chart by which I can sl'iowthcrcon every important city properly located as to time position that touches or comes near any divisional line, whereby I can thus easily group all the big cities in the United States and in Europe etc., while if I employ a regular or true mcridiuually divided chart, plan or table with a map I could only show a few cities. By arranging the cities in groups alpha betically any city is easily located and its correct position as to international time located, so that the reading of the device is very simple to understand, involving no calculations, being all readable at a glance, and impossible of misinterpretation.

It will of course be understood'that if desired I can employ a true outline map of the world on the chart without alphabetical arrangement of names but with the places in their true geographical position. By this method I could not provide as many names on the chart and it would further need a knowledge of geography to locate the names whereas by the alphabetical arran 'ement of the names, as previously set forth, it is only necessary to know how to read. Thus at any time one may look, local time can be seen by the ordinary clock on top and any leading citys time throughout the world by locating that city on the chart and following the divisional line nearest it, at the top of which on the indicator will be shown the correct time in that city.

The indicator may-be subdivided as desired although I have shown, in the mascot instance, the quarter hours and a so by shading the 111 ht and day hours. The spaces between t 1e divisional lines as shown may be further subdivided if desired.

1tv will be further understood that it is only necessary to have the local time on the divisional chart to correspond with the time on the ordinary clock and as the clock and the indicator travel properly with respect to each other vthc time of practically the world or the whole twenty-four hours will be shown correctly at any pointand continuously at any time it may be. inspected, the daylight hours and the night hours being clearly distinguished by the shadings on the background of the indicator.
