ALARM-CLOCK.

To all whom it may concern:

Be it known that I, Aoi-num AISERMAN, a citizen of the United States, and a resident of Kankakee, in the county of Kankakee and State ot Illinois, have invented a new and Improved Alarm-Clock, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a mechanism embodying a bell ringing alarm operatable by the time actuating mechanism of the clock; to provide a mechanism wherein the setting of the time for the alarm is operated simply and accurately to the minute; to provide a mechanism whereby the reversing of the alarm mechanism is prevented; to provide a mechanism whereby the operation of the alarm is prevented; to provide a structure for carrying the alarm bell on the frame of the clock; and to provide a combined time winding` and time setting device wit-hin one and the same structure.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters ot reference denote corresponding parts in all the views, and in which- Figure 1 is a vertical longitudinal section of a clock constructed in accordance with the present invention; Fig. 2 is a front elevation of a clock constructed in accordance with the present invention; Fig. 3 is a cross section taken on the line 3 3 in Fig. 1; Eig. 4 is a cross section taken on the line 4 4 in Fig. 1; and Fig. 5 is a longitudinal vertical section of the spring arbor and the power transmission wheel connected therewith; Eig. is a detail view in diagrammatic arrangement ot the alarm operating mechanism; Fig. 7 is a front view of the alarm setting and operating mechanism; Fig. 8 is a detail view showing the hammer-releasing device and the engaging wheel therefor; and Fig. 9 is a detail view of the time setting wheel and the alarm-releasing attachment connected therewith.

In the present invention, which pertains more particularly to the equipment of a clock with an alarm attachment, no alteration is made in the time mechanism. rThe gear 'l' is ixedly attached to a spring barrel` 9. The spring barrel 9 contains a spiral spring 10, to which it is connected by the end 11 of the said spring. The opposite Specification of Letters Patent.

Application filed July 15, 1909.

Serial No. 507,713.

end of the spring is anchored to an arbor 6, as shown at 12 in Fig. 5 of the drawings.

Fixedly mounted on the arbor G is a winding gear 13, which is held in toothed engagement with a gear 14 ixedly mounted upon a winding stem 15, upon which a winding handle 16 is mounted.

The stem is loosely mounted about an arbor 17, carrying the minute hand of the clock. The arbor 17 is provided at the end opposite that carrying the hand 18 with a squared extension 19 to receive a time-setting key 20. The key 20 is provided with a knurled head 21 adapted to rest within theloop of the handle 16. The loop of the handle 16 normally rests over the head 21 of the key, and prevents the withdrawal of the same from engagement with the squared extension 19 of the arbor 17. By turning the handle 16 to one side the key 2O may be withdrawn from the stem 15.

Then winding, the spring 10 exerts an expansion force upon the spring barrel 9 and upon the arbor 6. To the spring barrel 9 is lixedly attached the gear wheel 7, which is connected to the 'time operating mechanism ot the clock, The gear wheel S is xedly mounted upon the arbor G.

In winding the spring 10, the stem 15 is rotated by the handle 1G rotating the gear wheels 13 and 14, thereby revolving 't-he arbor 0 and winding the sprino' l() thereon.

The spring barrel 9 is held against moving, in answer to the pull of the spring, by the gear 7, and the time operating mechanism connected therewith. When, however, the alarm operating mechanism is released, 'the spring 10 is permitted to expand and rotate the gear S. The spring 10 then drives the alarm operating mechanism. This action is controlled by the upturned extensions 22, 22, which are projected from 'the gear wheel 8 into the path oit the teeth (35, (35 oiB the cam 9.4.

The cam Q11 is formed oi' the shape substantially as shown in Figs. -le and G or' the drawings, having circular cams 25 and gear teeth 65, G5. It is the engagement by a head 27 ot a lever Z8 with the body of the cam 2a which arrests the winding action ot the arbor (3 for the purpose oi ringing the alarm. The lever 2S is provided with a spring section i9, at 'the end ot which is located the head 2T. The lever 28 is pivoted at in the movement frame of the clock. The lever 2S has a circular section 31, which extends around the arbor 6, and is provided with a straight extension 32, upon the end of which is mounted a small gear wheel 33. The gear wheel 33 is pivoted at within a slot formed in the end of the straight extension 32. The purpose of this mounting is that when the gear 8 is rotated in 'the direction impelled by the winding of the spring 10, the wheel 33, which normally rests in toothed engagement with a small pinion 36, is carried out of engagement therewith by moving in the direction of the arrow shown in Fig. 6. Vhen, however, the expansion of the spring is exerted to rotate the gear 8 backward, the wheel 33 is moved toward and into engagement with the said wheel 36.

The wheel 36 is mounted on an arbor 37, upon the opposite end of which is iixedly mounted a wheel 38. The wheel 38 is in toothed engagement with a small pinion 39, which is mounted upon a shaft 40, whereon is fixedly mounted a star wheel 41. The star wheel 41 is engaged and controlled by an oscillator 44, the tail 45 whereof is operatively engaged by the time train gears 23, whereby the said oscillator, 'the hammer arm 42 and the hammer 43 are held as each tooth of the time controlled wheel passes under the tail 45. As a rule it requires sixteen seconds for each of the said teeth to pass under 'the said tail 45. The intervals between the teeth may be arranged to suit. This construction and arrangement produce an intermittent ring of the alarm.

The expansion of the spring 10, operating upon 'the spring barrel 9 when the gear 8 is held stationary, transmits the power of the said spring to t-he train of gears constituting the time mechanism, which forms no part of the present invention except in so far that the time setting device for the alarm is controlled thereby. This control is effected by means of wheels 46 and 47 The wheel 47 is in toothed engagement with a small pinion 48 constituting one of the train 4 of gears forming the time mechanism for operating the alarm. rlhe wheel 47 is slidably mounted upon the arbor 17, and is forced out-ward thereon by a leaf spring 49. In 'the upper side of the wheel 47 are pro vided teeth 50, 50 which ride upon the under surface of the wheel 46. rThe wheel 46 has formed on the under side a raised crown 51, in which is formed indentations 26, 26 to receive the teeth 50 when alined therewith. The teeth 50 ride out of the indentations 26 by inclined surfaces 51a provided therein, and fall into the same perpendicularly. The wheel 47 is operated in time relation with the arbor carrying the hour hand of the clock.

Vhen the teeth 50, 50 over-ride and fall into the slots provided therefor, the leaf spring 49 is permitted to throw outward, re-

leasing the upturned lip 52, fixedly mounted upon and controlling the operation of the arbor 53 upon which the oscillator 44 is mounted. The leaf spring 49 is provided with fingers 54, which are adapted to extend over and surround the lip 52. Then the lip 52 is thus engaged it will be observed that the arbor cannot oscillate, thus imprisoning and holding rigid the wheel 41, and with it the arbor 4() and train of gears connected therewith back to the main spring 10.

By setting the wheel 46 with reference to the time dial, the slots into which the teeth 50 are inserted by the spring 49, is arranged. The wheel 46 is mounted upon a short shaft 55, at the outer end whereof is carried an index hand 56. The index hand 56 bears a fixed relation with the slots formed in the wheel 46, hence by moving the hand 56 to any fixed position upon the dial, the wheel 46 is compelled to assume a certain position relative to the wheel 47.

It is to regulate the position of the hand more accurately upon the dial that there is provided a smaller dial 57, imprinted upon the main dial, and wherein is mounted a small index hand 58. The index. hand 58 is rigidly connected with a small pinion 59, which is held in toothed engagement with the wheel 46. The arrangement between the wheel 46 and the pinion 59 is such that the hand 56 bears the relation to the hand 58 that the hour hand of the clock bears to the minute hand thereof. Hence, as the hand 56 is moved on the main dial of the clock, the hand 58 is moved by this smaller dial at a rate twelve times faster. That is to say, for each minute division that the hour hand is moved on the dial the smaller hand 58 is moved twelve of its subdivisions, which indicate the sixty minutes of the hour. By this arrangement the operator can bring the hour hand to a position on the main dial so that the alarm may bc set for such a time as nineteen min utes past the hour, with the certainty of having the alarm operate on that division of time.

The hand 56 is shifted by means of the rotary frame 61 of the crystal 6() of the clock. The rotary frame 61, wherein the crystal 60 is held, is held in the casing of the clock by the ridge formed by spinning inward the metal of the casing at 62. The frame is provided with a series of dogs 63, 63 set out from the inner face to extend into the path of the hand 56, to move the same about the dial when the frame 61 is rotated. It is to provide against undertaking to move t-he hand 56 backward that I have fixed the dogs 63 so as to under-act and lift by cam action the hand in the event of the frame being turned backward. The front face of the dogs 63, 63 are disposed to engage the end of the hand 56 and move the same positively to the clock face.

lt will be seen that a clock constructed in accordance with this invention, and as above described, is at all times ready to be wound, this being accomplished by grasping the handle 16 and rotating the same, transmiting the rotary action through the gears 13 and 14, the opposite ends of the springs 10 being anchored to the arbor 6 upon which the gear 13 is fixedly mounted, and the spring barrel 9 to which the wheel 7 of the time mechanism is fxedly attached. Then the spring is thus wound it is relatively anchored to the slow moving time mechanism. Then t-he winding mechanism is released by the hand of the operator, the spring immediately tends to unwind or expand backward through the gear 8. This action is prevented by the engagement of the leaf spring 49 with the lip 52, the leaf spring being held in a depressed position, as shown in Fig. 1 of the drawings. Hence it is, that the winding of the spring by the handle 16 at one operation winds the spring which is ready at all times to operate the time mechanism, and when permitted, the alarm mechanism.

The winding of the spring is accomplished without operating the alarm operating mechanism connected with the wheel 86, by the avoidance of the wheel 83, which is moved backward out of engagement with the wheel 66, as above set forth, when the gear 8 is rotated in a manner t0 wind the spring 10. rThis is the purpose of the loose mounting of the wheel 33 above described, and as shown in Figs. 4 and 6 of the drawings.

The alarm mechanism operates only when the teeth 59 aline with the indentations 26 provided in the wheel 46 to receive them. Then this alinement occurs the leaf spring 49 forces the wheel 47 outward until the lingers 54 release the lip 52, permitting the train of gears operating the star wheel 41 and the hammer 43 to operate the same. This operation continues, repeatedly striking the bell 64 and sounding an alarm until the body portion of the cam 24 strikes against the head 27 of the lever 28. Then this conjunction occurs the cam 24 is arrested, and with it the power transmission train operating the said alarm.

The body portion is brought into contact with the head 27 by reason of the extensions 22, 22 having engaged the teeth 65, 65, as in the manner of gear teeth, moving the cam 24 and the cams 25 past the head 27 during one complete rotation of theV gear 8, there being three of the teeth 65 and three of the extensions 22.

Then the alarm operating mechanism is released, the gear wheel 8 is rotated in the direction shown by the arrow in Fig. 6. For

each alarm the gear 8 rotates one complete rotation. In this revolution the three exten sions 22, 22 engage the teeth 65, 65 of the cam 24 successively, moving the cam in the direction opposite the rotation of the gear S. For each movement of the cam 24 by the extensions 22, the head 27 of the lever 28 is lifted over the cam 25, the spring section 29 of the lever 28 permitting the head 27 to thus rise. The head 27 strikes into the recess between the next succeeding cam 25 to aline and hold the cam 24 after being disengaged by one of the extensions 29. This action holds the cam 24 in position so that the fo-llowing tooth 65 is in the path of the following extension 22. The operation of the second extension 22, in moving the cam 24, is the same as above described. This ac` tion is repeated by the three extensions 22 in their engagement with the teeth 65, 65, the last extension 22 placing the head 27 in the recess between the last cam 25 and the end 67. Then now the next extension 22 impinges upon the cam 24, it strikes upon the body portion in which there are no teeth, and which arrests the movement of the gear 8, and the extensions 22 carried thereby.

Then the spring 10 is re-wound, the gear 8 is moved by the arbor 6 in the direction opposite that shown by the arrow in Fig. 6. As above stated, this movement of the gear S does not operate the train of gears connectw ing the same with the alarm, by reason of the fact that the gear 38 is moved out of conta ct with the pinion 36. In thus rewinding the spring 10, the extensions 22, 22 reverse the cam 24 engaging the teeth 65, 65 from the direction opposite that previously described. The extensions 22, 22 place the cam 24 and the head 27 in the position shown in Fig. 6 of the drawings. The gear S is arrested in this position by the extension 22 striking upon the side of the cam 24 between the first tooth 65 and the end 67 ln this position the gear 8 remains stationary until the alarm operating mechanism is released.

It will be noticed that during the operation, and at the beginning of the winding operation just above described, the wheel 3?, is forced out of engagement with the wheel 36, thereby avoiding the operating of the stai' wheel 41 and hammer 43 through the train of gears connected therewith. This operation is repeated for each winding of the clock, the winding having the effect of winding the main spring to operate both the time mechanism and the alarm mechanism.

lf it is desired that the alarm be not operated, the hand 56 is moved until it passes over and impinge upon the end of the extension 66 set up from the end of the spring 49. The hand 56 being thus set over and resting upon the spring 49, it is not permitted to rise when the teeth 50, 50 aline with the indentations 26 formed in the wheel 46, and being thus controlled the lip 52 of the oscillator 44 is imprisoned, and the alarm mechanism prevented from operating. Thus, by moving the hand 5G the alarm may be adj usted to occur at any minute desired by the operator, and by the further movement of the said hand the alarm may be prevented from operating.
