ELECTRIC PROGRAM-CLOCK.

SPECIFICATION forming part of Letters Fatent No. 563,052, dated June 30, 1896.

Application filed October 12,1895.

1'0 all whom it may concern.-

Be it known that I, DORA OGDEN, a citizen of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented a new and useful Automatic Time-Signal, of which the following is a specification.

My invention relates to means for operating a steam or other whistle or signal, automatically, by means of a standard or master clock.

The object of this invention is to provide means whereby the whistle or other signal used by a factory for indicating the time for beginning and quitting work may be automatically operated by a clock located at said factory; and my further object is to provide means whereby the whistles or signals of a series of factories, each having a clock forming a part of a system of time-regulation controlled by a central regulating-clock, may be automatically operated by said central clock.

The accompanying drawings illustrate my invention.

Figure 1 is a view of the face of the local clock used in my device, a portion of the face having been broken away. Fig. 2 is an elevati on of the portions of my device other than the regulating-clock, the signal being shown on a smaller scale. Fig. 3 is a view on line 3 3 of Fig. 1. Fig. et is a view on line et a of Fig. 2, and Fig. 5 is a side elevation on line 5 5 of Fig. 2.

In the drawings, 6 indicates the framework of the clock mechanism, 7 the hour shaft thereof, and 8 a gear-wheel carried by said hour-shaft and actuated by the clock-train. Secured to gear 8 and projecting from the face thereof is a pin 9, the purpose of which will be hereinafter described. Securedto the hour-shaft is a disk provided with a series of radial contact-points 10, which are adapted to be engaged by the terminal 11, secured to the pivoted arm 12. Arm 12 is pivoted to the frame 6 and is adapted to be drawn up into the position indicated by dotted lines by means of the electromagnet 13, said magnet being energized by the operation of a master clock (not shown) at stated periods in the o'r dinary manner.

Terminal 11 may be fixed in position to en- Serial No. 565,442. (No model) gage with points 10, if so desired, and this construction is the one used when the signal is not to be controlled, together with others, by a master-clock.

Mounted on frame (5 is a shaft ll, to which are secured wheels 15 and 10, wheel 16 being provided with a series of teeth adapted to be engaged by pin 9. lVheel 15 is composed of a series of metallic segments 17 and a series of non-metallic or non-conducting segments 18, the segments alternating around the periphery of the wheel, except in one place, where three non-conducting segments are placed in succession. The total number of segments is equal to the number of days and nights in a week, a metallic segment being provided for each day of the week except Sunday, for which, together with each night, a non-conducting segment is provided.

19 indicates an insulated standard secured to frame 6, and to this standard is secured a spring-terminal 20, said terminal engaging with the periphery of wheel 15.

33 is an ordinary volute spring, one end of which is secured to the shaft and the other end of which is secured to the frame 26.

3'11: indicates an arm secured to shaft 27 and adapted to engage with the adjustable stop 35,seeured to frame 26. An arm 36 is mounted upon shaft 27 and is adapted to turn the shaft and thereby wind up spring Arm 36 is allowed a certain freedom of movement on shaft 27 by means of a pin 37 and slot 38, as shown in Fig. 2, and is kept in a position to move shaft 27 forward by means of a spring 39, one end of which is secured to the arm and the other end of which is secured to the shaft. Shaft 28 is provided with a gear, which engages with gear 32, and is also provided ICO with an escapement-wheel 40, which is e11- gaged by pallet 41, said pallet being pro vided with a pendulum-rod 42 and adjustable weight 43. Shaft 29 is provided with a gear 44, which meshes with gear 32, and is also provided with a disk 45, provided with a notch 46 in its periphery.

47 is a cam adj ustably mounted on shaft 29, provided with slot 48, and secured to disk 45 by means of screw 49 passing through said slot.

50 indicates a spring-terminal, the free end of which rests upon the periphery of disk 45.

51 indicates a terminal which lies in front of spring-terminal 50 and is so placed that it will be engaged by terminal 50 when the free end of said terminal falls into notch 46, but will be out of engagement therewith when the free end of said terminal rests upon the periphery of said disk.

52 indicates a pivoted arm supported by a spring 53' and provided with a pin 54, which is adapted to engage arm 36. A cord or chain 55 is secured at one end to the free end of arm 52 and at the other end is secured to cord 23.

Pivoted at 50 is an insulated arm 57, one end of which engages cam 47 and the other end of which is provided with two terminals 58 and 59, said terminals being insulated from each other. The free ends of terminals 58 and 59 play between terminal points 60, 61, and 62, terminal 58 engaging either terminal 60 or 61, and terminal 59 engaging either terminal 61 or 62, for a purpose hereinafter eX- plained.

63 indicates a metallic switch-lever, pivoted at 04 and provided with a spring 65, which tends to throw the switch-lever upward into engagement with terminal 66. Lever 63 is provided with an extending armature 67, which overhangs the cores of the electromagnets 68. The free end of lever 63 is adapted to be engaged. by the metallic hook 69, pivoted at 7 O. Said hook is provided with an armature 71, which overhangs the core of an electromagnet 72, and is also provided With an arm 73, to which is secured one end of spring 74, the other end of said spring being secured to some stationary part. A. stop is provided to limit the operation of spring 74, said spring operating to place hook 69 in a position to engage lever (33.

79 indicates a conductor leading from terminal 11 to one terminal of the cut-out 7 S, 80 a conductor leading from the same terminal of the cut-out to the metallic frame 26, and 81 indicates a conductor leading from the opposite terminal of the cut-out to the terminal 58.

82 indicates a conductor leading from terminal 20 to the coil of magnet 72, and 83 illdicates a conductor leading from the said coil through pivot 70 to hook 69.

84 indicates a conductor leading from terminal 50 to one pole of the battery 76, and 85 indicates a conductor leading from the other pole of the battery to lever (53.

86 indicates a conductor leading from lever 63 to the coils of magnets 68, and 87 indicates a conductor leading from said coils to terminal 51.

88 indicates conductors leading from terminals 00 and 62 to one terminal of the 1110- tor-armature, and 89 indicates a conductor leading from terminal 61 to the other terminal of the motor-armature.

90 indicates a conductor leading from terminal 59 to one terminal of the field-magnet of the motor, and 91 indicates a conductor leading from the other terminal of the fieldmagnet to terminal 60.

92 indicates a conductor connected to conductor 82, at a point intermediate its length, and leading to one terminal of push-button 77, and 93 indicates a conductor connected to conductor 79, at a point intermediate its length, and leading to the other terminal of the pushbutton.

Supposing that it is desired that the signal be sounded or made at seven a. 111., twelve 111., and one and six p. 111., all except four of the contact-points 10 are bent outward, as shown in Fig. 3, so that their ends lie out of reach of terminal 11, the four points which are not so bentbeing those which lie opposite terminal 11 at the hours indicated. Starting with the clock at 6.55 a. 1n., as shown, the operation is as follows: lVhen the clock has advanced so as to indicate seven a. 111., the hourhand, terminals 10, and gear 8 moving forward together, a current is sent from the standard clock (not shown) through the coil of magnet 13. The magnet, when thus energized, draws arm 12 up to the position indi cated in dotted lines, terminal 11 is thereby thrown down to the position indicated and comes into contact with one of the points 10. Then the magnet 13 is energized at hours other than those named above, terminal 11 is thrown down, but fails to make contact with one of the points 10 owing to the fact that those particular points have been bent out of the way, as described above. At the instant that contact is made between one of points 10 and terminal 11 the following circuit is completed: from the battery through conductor 84, terminal 5(), disk 45, frame 26, conductors 80, conductors 79, terminal 11, contactpoint-10, frame 6, shaft 14, one of segments 17, terminal 20, conductor 82, the coil of magnet 72, conductor 83, pivot 70 and hook 69, lever 63, and conductor 85 back to the battery. The completion of this circuit energizes magnet 7 2'and causes hook 69 to be drawn away from the end of lever 63. Lever 63 is thereby freed, and, on account of the action of spring 65, flies upward and comes into contact with terminal 66, this movement of lever 63 at the same time breaking the circuit described above, depriving magnet 72 of its power and IIO allowing hook 69 to be drawn back into place by spring 74. When lever 63 comes into contact with terminal 66, a circuit is completed through the motor through the following parts: from the battery through conductor 84, terminal 50, disk 45, frame 26, conductor 80, cut-out 7S, conductor 81, terminals 58, terminals 61, conductor 89 to one terminal of the motor-armature, from the other terminal of the motor-armature through conductor 88, terminals 62, terminals 59, conductor 90, through the field-coil of the motor, conductor 91, terminal 66, lever 63, and conductor 85 back to the battery. The completion of this circuit through themotor causes it to revolve in the proper direction to cause cord 23 to be wound upon drum 22. The winding up of cord 23 upon drum 22 causes arm 24 of the signal device to be drawn down and the signal is thus sounded and continues until arm 24 is released in a manner to be explained. Cord 55 being secured to cord 23 advances with it, thus drawing down arm 52 against the action of spring 53. Pin 54 of said arm engages the outer portion of arm 36 and causes said arm to move downward to the position indicated in dotted lines in Fig. 2, pin 54 slipping from the end of arm 36 when this position is reached. The downward movement of arm 36 winds up spring 33. Spring 33 then causes gear 32 to move in the direction indicated by the arrow thereon, said motion continuing until arm 34 comes into contact with stop 35. The forward movement of gear 32 is regulated and controlled by means of escapement-wheel 40, pallet 41, and pendulum 42 43, and said movement of gear 32, through gear 44, causes disk 45 and cam 47 to move in the direction indicated by the arrow thereon. ward movement of cam 47 continues, said camv comes into contact with arm 57, cansing said arm to swing upon its pivot. This movement of arm 57 first causes the 1notorcircuit to be broken, terminals 58 61 and 59 62 being separated, and the motor is therefore stopped, and then a new circuit is established as follows: from the battery through conductor 84, terminal 50, disk 45, frame 26, conductor 80, cut-out 78, conductor 81, terminals 58 and 60, conductor 88, through the motor-armature, conductor 89, terminals 61, terminals 59, conductor 90, through the fieldmagnet of the motor, conductor 91, terminal 66, lever 63, and conductor 85 back to the battery, thus reversing the motor and cansing cords 23 and to be unwound from drum 22, arm 52 returning to its original position and the signal being released. Pin 54 is enabled to pass the end of arm 36, owing to the arrangement of slot 38 in said arm and pin 37 in shaft 27, as is clearly apparent from Fig. 2. During the entire movement of the motor, both in the forward and in the back ward direction, disk 45 and cam 47 are constantly advancing, and when notch 46 of disk 45 reaches a point opposite the free end of As the for-' terminal 50 the said end of said terminal springs down into the notch and thus c0111- pletes the following circuit by bringing terminals 50 and 51 together: from the battery through conductor 84, terminals 50, terminals 51, conductor 87, through the coils of magnets 68, conductors S6 and 85, back to the battery. The completion of the above-mentioned circuit causes the magnets 68 to be energized, these in turn drawing down armature 67, thus breaking the contact between lever 63 and terminal 66, and thus stopping the motor, and this movement brings the free end of lever 63 into engagement with hook 69. As disk 45 continues to advance, notch 46 is moved away from the free end of terminal 56 and said free end is forced out upon the periphery of the disk, thus breaking the contact between terminals 50 and 51. Disk 45 and cam 47 continue to advance until arm 34 comes into contact with stop 35, cam 47 at the same time reaching a position which will allow arm 57 to return to the position shown in Fig. 2. The entire apparatus is then in its original position and is ready to be again operated in the manner described above.

(Jam 47 is made adjustable in order to regulate the reversing mechanism of the motor.

The time consumed in one revolution of disk 45, and the consequent length of signal, is regulated by pendulum 42 43.

\Vhen the clock has advanced to a position indicating about 6.30 p. 111., pin 9 has reached a position where it will engage one of the teeth of wheel 16, and a further advance of the hour-shaft causes said wheel to be advanced one division, the movement of said wheel causing a similar movement of wheel 15, thus bringing one of the non-conducting segments 18 opposite terminal 20. The mechanism shown in Fig. 2 therefore remains in.- operative during the night, owing to the fact that no ciurent can pass through the coil of magnet 7 2. At 6.30 a. 1n. pin 9 again causes wheels 16 and 15 to advance one segment, thus bringing terminal 20 into engagement with one of the conducting-segments 17,unless the day happens to be Sunday, a non-conduetin g segment being introduced for the daytime of Sunday. Out-out 78 is provided so that the mechanism may be made inoperative upon any days on which the factory is not running, and button 77 is provided so that if it is desired to operate the signal at some unusual hour it may be done.
