HENRY M. HUNT, OF INDIANAPOLIS, INDIANA.

STRlKlNG-CLOCK.

$PEGIFIGATION forming part of Letters Patent No. 735,261, dated August 4, 1903.

Application filed December 1,1899. Serial No. 738,852. (No model.)

To alt whom it may concern:

Be it known that I, HENRY M. HUNT, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Striking- Clock, of which the following is a specification.

My invention relates to an improvement in mechanical movements particularly adapted for use in striking-clocks.

The object of my invention is to produce a simple but effective mechanical movement by means of which a series of signals may be operated so as to indicate successive instants of time.

In the drawings I have shown my device as applied to a clock in such manner as to indicate each minute by an audible signal which maybe readily distinguished from each preceding and succeeding signal.

The accompanying drawings illustrate my invention. v

Figure 1 is a view of the face of a clock embodying my invention. Fig. 2 is a front elevation thereof with the face removed. Fig. 3 is a plan. Fig. 4 is a perspective view of my improved mechanical movement. Fig. 5 is a section, on a larger scale, on line 5 5 of Fig. 2. Fig. 6 is an enlarged elevation of a portion of the mechanism. Fig. 7 is an elevation of a modification. Fig. 8 is a section on line 8 8 of Fig. 7. Fig. 9 is an elevation of-a further modification, showing electrical connections. Fig. 10 is a rear view of disk 20. Fig. 11 is a similar view of disk 24. Fig. 12 is a side elevation. Fig. 13 is asectional detail on a line drawn between teeth 43 and 44 in a plane parallel with Fig. 2.

In the drawings,12 indicates the main shaft, which projects through the face-plate 12 and is provided at its end with a portion 12", to which the minute-hand 13 may be secured. Rotatably mounted upon shaft 12 is a sleeve 14, on the outer end of which is secured the five-minute hand 15 and to the inner end of which is secured a disk 16. Rotatably mounted upon sleeve 14 is a sleeve 17, to the outer end of which is secured an hour-hand 18 and to the inner end of which is secured a disk 19.

Secured to shaft 12, so as to rotate said shaft, is a disk 20, the periphery of which is center than do pins or teeth 25.

divided into ten equal spaces, Fig. 10. Each of the first nine spaces is provided with one or more projecting pins 21, which pins are varied in number in regular succession from 1 to 9. The remaining space on this disk is left blank. Projecting from one face of disk 20 are two pins 22, which are fourtenths of a revolution apart. Projecting from the other face of said disk is a series of ten pins or teeth 23, by means of which the said disk may be driven, Figs. 3 and 5. Betatably'moun ted upon shaft 12 is a second plate or disk 24, Figs. 5 and 11, from one face of which projects a series of twelveequally- 'spaced pins or teeth and a single pin 26,

which pin lies at a greater distance from the Projecting from the opposite face of disk 24 is a series of twelve pins or teeth 27. Projecting from this face of disk 24 is a pin 28, which extends into a slot 29, formed in disk 16, Fig. 5 and dotted in Fig. 4. Slot 29 is concentric with the shaft 12 and is alittle more than thirty degrees in length, the arrangement being such that disk 24 may be given a reciprocating movement of one-twelfth of a revolution without moving disk 16.

Rotatabl-y mounted upon sleeve 14 is a disk or plate 30. Projecting from one face of the disk 30 is a series of twelve pins or teeth 31, and extending from the opposite face is a similar series of pins or teeth 32., Projecting from this face of disk 30 is a pin 33, which pin projects into a slot 34, Fig. 4, similar to slot 29, formed in disk 19.

It will be readily understood that an arm or segment of sufficient width to carry a slot of a little more than thirty degrees in length might be substituted for either one of the disks 16'and 19.

The periphery of disk 24 is divided into twelve equal parts, and the first two of the portions are left blank, Fig. 11. Projecting from each of the second two portions is a single pin 35. From each of the third pair of portions two pins project, and each of the succeeding pair of portions is provided with an additional pin, so that each of the last pair of portions is provided with five pins. The periphery of disk 30 is divided into twelve equal portions, from each of which projects one or more pins 36,Fig. 4, the numher of pins in each section varying in regular order from 1 to 12. The several disks and hands operated thereby are driven by means of a suitable spring or other motor 37, controlled by the usual pallet 38 and escapement-wheel 39, which are connected to said motor by means of the usual train of gears. Said train of gears, Fig. 12 and dotted in Fig. 2,drives a shaft 40, which in turn by means of a pair of equal gears 41 and 42 drives a shaft 43 in the opposite direction. Secured to shaft are two driving- teeth 44 and 45, Fig. 4. Tooth 44 is arranged to engage pins or teeth 27 of disk 24, and tooth 45 is arranged to engage pins or teeth 31 of disk 30. Secured to shaft 43 are three drivingteeth 46, 47, and 43, Figs. 4, 5, 6, the arrangement of said teeth being such that tooth 46 may engage pins 23 of disk 20, tooth 47 may engage pins 27 of disk 24, and tooth 48 may engage pins 31 of disk 30. Tooth 45 is arranged slightly in advance of tooth 44, and shaft 40 rotates so that said teeth will drive the disks 24 and 30, respectively, backward.

Teeth 46, 47, and 43 are arranged in the order named around shaft 43, which rotates so as to cause said teeth to drive disks 20, 24, and 30, respectively, forward. Mounted in suitable bearings parallel to the several shafts already mentioned is a shaft 49, Figs. 3, 4, 6, upon which is secured a pair of gears 50 and 50'. Gear 50- is arranged to be engaged by pin 26 of disk 24, and gear 50 is arranged to engage any one of pins 32 of disk 30 when gear 50 is rotated, and thus drive said disk in a clockwise direction. Revolubly mounted on shaft 49, but secured so as to rotate together, is a pair of gears 51 and 51. Gear 51 is so arranged as to be engaged by either one of pins 22 of disk 20 and gear 51 is arranged to engage any one of pins 25 of disk 24. The teeth of gears 50 and 51 are so spaced that after either has operated to advance its adjacent disk 30 or 24, respectively, the said disks may be freely rotated in either direction without engaging the said teeth. The teeth 21, 35, and 36 of disks 20, 24, and 30, respectively, may be caused to operate any one of a number of convenient forms of alarm or signal mechanisms. In Figs. 2, 3, 5, and 6 I have illustrated a form in which I provide three bells 52, 53, and 54, the said bells having tones easily distinguishable one from the other. Bell 52 may be struck by a hammer of any well-known form, said hammer having an arm 56, the end of which may be caused to lie in the path of movement of pins 36. Bell 53 may be struck by a similar hammer 57, having an operating-arm 58, which may be made to lie in the path of movement of pins 35. A similar hammer 59 is arranged to strike bell 54, and the end of its operatingarm may be caused to lie in the path of movement of pins 21. Each of the said hammers may be drawn down to striking position by a suitable spring or otherwise. As will appear in the description of the operation,

disks 24 and 30 are intermittently oscillated in both directions, and in order to prevent the pins 35 and 36 from engaging arms 58 and 56, respectively, during the forward oscillation of said disks I mount upon shaft 43 a cam 61, Figs. 6, 9, which is adapted to engage an arm 62, which in turn engages arms 63, secured to hammers 55 and 57, so that during that portion of the revolution of shaft 43 which coincides with the forward oscillation of said disks arms 56 and 58 are lifted out'of the paths of movement of pins 36 and 35, respectiveiy. The cam 61 and connected portions perform a double function. Shaft 43 is so connected to the train of driving-gears as to make a complete revolution each minute, and said shaft carries upon its face end a seconds-hand 64, Figs. 1,12. Cam 61 is provided with a sudden drop 65, Fig. 6, which is so arranged that as soon as the disks 24 and 30 have completed their reverse or clockwise oscillation arm 62 is withdrawn from arms 63 with sufficient suddenness to cause hammers 55 and 57 to strike simultaneously their respective bells 52 and 53, thus causing once each minute an easily-distinguishable signal, which I will hereinafter designate as the counting-signal. At the same time arms 56 and drop down into paths of movement of the pins 36 and 35, respectively.

The operation is as follows: Starting with the hands in the position shown in Fig. l, which indicates twenty minutes past eight, the parts will then be in the position shown in Fig. 6. Just as the seconds-hand 64 is brought to the position shown in Fig. 1 the mechanism has operated so as to strike eight, two, or 8.20. An advance of shaft 43 about one-half of a revolution, or thirty seconds, then brings shoulder 65 of cam 61 beneath arm 62, and thus allows hammers 55 and 57 to drop simultaneously into engagement with bells 52 and 53, thus sounding the counting-signal and indicating that the parts are in position for the listener to begin the count. At this time disk 30 is in such position that the group of pins 36 immediately to the right of arm 56 is composed of eight pins, disk 24 is in such position that the first group of two pins 35 lies to the right of arm 58, and disk 20 is in such position that the first group of pins 21 (composed of one pin) lies to the left of arm 60. Immediately following the simultaneous dropping of hammers 55 and 57 tooth 45 comes into engagement with one of pins 31 of disk 30 and drives said disk backward through one-twelfth of a revolution, thus drawing the adjacent pins 36 beneath arm 56 and causing hammer 55 to strike bell 52 eight times, and thereby indicating the hour. A continued advancement of shaft 43 brings tooth 44 into engagement with pins 27 of disk 24, the said disk being driven backward through one-twelfth of a revolution and drawing the two adjacent pins 35 beneath arm 58, so as to cause hammer 57 to strike bell 53 two times, and thereby indieating the number of ten-minute groups. A continued advancement of the shaft 43 brings tooth 46 into engagement with one of pins 23 of disk 20 and drives disk 20 forward through one-tenth of a revolution, so as to draw pin 21 beneath arm 60 and cause hammer 59 to strike bell 54 one time, thus indicating the minutes past the ten-minute period indicated by the bell 53. At the same time hand 13 is moved forward to the one minute mark and the group of two pins 21 is brought to the left of arm 60., At this time the seconds-hand again reaches its starting-point. As shaft 43 advances to indicate the first part of the following minute tooth 47 is brought into engagement with one of pins 27 and oscil-' lates disk 24 forward through one-twelfth of a revolution, thus returning the same group of pins 35 to the right of arm 58. Immediately following the action of tooth 47 tooth 48 is brought into engagement with one of pins 31 of disk 30 and drives said disk in a return or forward direction, so as to return the eighth group of pins 36 to the right of arm'56.

When the parts have reached the positions just described, the teeth 44, 45, 46, 47, and 48 are in such positions that the several disks may be freely rotated in either direction. The teeth of gears 51, 50, and also lie insuch position that they will not be engaged by any of the pins of theadjacent disks, so that by lifting hammers and 57 and by any suitable means, such as aseries of fingers 66, the hands 13, 15, and 18 may be set at any desired point. Up to this point the oscillation of disks 24 and 30 have produced no efiect upon the hands 15 and 18, respectively, because pins 28 and 33 have been merely oscillated from one end to the other of their respective slots 29 and 34 in disks 16 and 19,respectively. The operation just described is repeated each minute for four minutes, the disks 24 and 30 being oscillated first backward and then forward through one-twelfth of a revolution and disk 20 being advanced one-tenth of a revolution each minute. When the hands stand so as to indicate 8.24 and thirty seconds,the countingsignal has been sounded by the simultaneous action of hammers 55 and 57, the eighth group of pins 36 lies to the right of arm 56, the first group of two of pins 35 lies to the right of arm 58, the group of five pins 21 lies to the left of arm 60, and one of pins 22 is just coming into engagement with one of the teeth of gear 51. An advancement of shaft 43 from this position brings tooth 45 into engagement with one of pins 31, so as to drive disk 30 backward and cause hammer 55 to strike bell 52 eight times. Tooth 44 then engages one ofpins 27 and drives disk 24 backward, so as to cause hammer 57 to strike bell 53 two times. In this position pins 28 and 33 of disks 24 and 30, respectively, lie at the extreme left or rear ends of slots 29 and 34, respectively, of the disks 16 and 19. Tooth 46 then comes into engagement with one of pins 23 of disk 20 and drives said disk forward, so as to cause hammer 59 to strike bell 54 five times. At the same time pin 22 comes into engagement with one of the teeth of gear 51 and causes saidgear and .gear 51 to rotate, thus bringing one of the teeth of gear 51 into engagement with one of pins 25 of disk 24, so as to advance said disk through one-twelfth of a revolution forward. This advancement of disk 24 by gear 51 so shifts the disk 24 that when tooth 47 comes into position to engage one of pins 27 the disk is one-twelfth of a revolution in advance of what it would have been had gear5l' remained stationary, and pin 28 lies at the extreme right or forward end of the slot 29 of disk 16. A continued advancement of shaft 43 causes tooth 47 to engage the proper pin 27, so as to advance disk 24 forward through another one-twelfth of a revolution. This movement of disk 24 causes pin 28 to drive disk 16 through one-twelfth of a revolution,

thus advancing hand 15 from IV to V on the face of the clock,this additional movement of disk 24 bringing the second group of two pins 35 to the right ofarm 58. Disk 30 is then returned forward by tooth 48 through onetwelfth of a revolution, and the parts are in position to strike eight, two, six, or 8.26. The operation previously described is repeated each minute until 8.28 and thirty seconds, at which time hand 18 still remains opposite VIII, hand 15 stands at V, hand 13 stands at 8, and hand 64 stands at 30. At this ti me the counting-signal is again given and the eighth group of pins 36 lies to the right of arm 56, the second group of two pins 35 lies to the right of arm 58, the group of nine pins 21 lies to the left of arm 60, and the second one of pins 22 is coming into engagement with one of teeth on gear 51. As the several parts are ad vancing in the manner already described and cause the several bells to sound the disk 24 is again advanced onetwelfth of a revolution by the action of gears 51 and 51, and the action of tooth 47 on said disk advances hand 15 to VI. The operations already described are continued in proper sequence each minute, the disk 20 being advanced forward one-tenth of a revolution each minute and disk 24 being advanced forward one-twelfth of a revolution twice in every ten minutes, this movement being addition to the backward and forward oscillations of one-twelfth of a revolution each min-v ute. At 8.58 and thirty seconds we have the following conditions: Hand 18 remains opposite VIII, with disk 30, so that the eighth group of pins 36 lies to the right of arm 56 and pin 33 at the forward end ofslot 34, hand 15 stands opposite XI, and the second group of five of pins 35 lies to the right of arm 58, with pin 28 at the forward end of slot 29, and the group of nine pins 21 of disk 20 lies to the left of arm 60. At this time one of pins 22 is coming into engagement with one of the teeth of gear 51. When the parts have reached these positions, the counting-signal has just sounded, disk 30 is driven backward through end of slot 29. ward one-tenth of a revolution, thus striking one-twelfth of a revolution, thus striking bell 52 eight times, and pin 33 lies at the rear end of the slot 34. Disk 24 is then driven backward one-twelfth of a revolution, thus striking bell 53 five times and bringing pin 28 to the rear Disk 20 is then driven forbell 54 nine times. The advancement of disk 20 at this point causes one of pins 22 to rotate gears 51 and 51, the gear 51 thus operating to advance disk 24 forward one-twelfth of a revolution, so as to bring pin 28 to the forward end of slot 29. As soon as this occurs tooth 47 engages one of pins 27 and continues the advance of disk 24 through another one-twelfth of a revolution, said advance moving hand 15 to XII. During this last forward advancement of disk 24 pin 26 thereof drives gears 50 and 50 so as to cause gear 50 to engage one of pins 32 and advance disk 30 forward one-twelfth of a revolution, thus bringing pin 33 thereof to the forward end of slot 34. As soon as this advancement of disk 30 is completed tooth 48 comes into engagement with one of pins 31 thereof and continues the forward advancement of head 30 another one-twelfth of a revolution, thus bringing the ninth group of pins 36 to the right of arm 56 and hand 18 opposite IX. At 8:59 and thirty seconds, hand 18 is opposite IX, the ninth group of pins 36 lies to the right of arm 56, and pin 33 lies at the forward end of slot 34 5 hand 15 stands opposite XII, the first blank space of the periphery of disk 24 stands to the right of arm 58, and pin 28 lies at the forward end of slot 29; hand 13 stands opposite 9, and the blank portion of the periphery of disk 20 lies immediately to the left of arm 60. The countingsignal is then given, after which disk 30 is driven backward one-twelfth of a revolution, so as to strike bell 52 nine times. Disk 24 is driven backward to carry the first blank portion of the periphery of disk 24 beneath arm 58, so that bell 52 is not sounded, and the blank portion of the periphery of disk 20 is driven forward beneath arm and bell 54 is not sounded. Each succeeding minute is indicated, as already described.

It will be readily understood that many different forms of sounding mechanisms or signals may be used in connection with and operated by the mechanical movement just described. In Figs. 7 and 8 I haveshown a construction in which I provide a series of vibrating tongues 68, 69, and 70, the said tongues being in positions to be engaged by the projecting pins 36, 35, and 21, respectively. In order to withdraw tongues 68 and 69 during the return oscillation of disks 24 and 30, the said tongues may be mounted upon a pivoted frame 71, which may be swung at the proper time once each minute by means of an arm 72, operated upon by cam 61.

The mechanical movement just described may be also used to operate electrically a purnber of signals which may be placed at widely separated points. A construction such as is shown in Fig. 9 would be applicable in this case. I provide a series of terminals 73, 74, 75, and 76, which are insulated from the frame of the movement and which are arranged to be engaged by pins 36, 35, and 21, respectively. For reasons already stated terminals 73 and 74 should be intermittently withdrawn from the paths of movement of the pins 36 and 35. Said terminals may therefore be carried by a pivoted frame 77, which may be properly swung by a lever 78, acted upon by cam 61.

Suitable holding means may be provided to prevent the parts from becoming accidentally misplaced; but for the sake of clearness such means have been omitted from the drawings, as any desired form may be used.

It will be readily understood that disks 20, 24, and 30 may be provided with any desirable forms of operating means other and equivalent to the several sets of pins mentioned without departing from my invention.
