- My invention relates to improvements in alarm-clocks of that class wherein the spring of the alarm-striking mechanism may be wound once in eight days or with more or less frequency, as desired, for the purpose of actuating the hammer of an alarm bell or gong at the required period once in every twelve or twenty-four hours of each of a number of days, thus dispensing with the labor of winding the alarm mechanism every day and enabling said alarm mechanism to be used to good advantage in connection with that style of clocks which are wound once in eight days, whereby the clock-train and the alarm mechanism may each be wound at the required intervals of eight days.
- the invention also includes means by which the alarm mechanism may be set or adjusted to release the striker once in every twelve hours instead of once in every twenty-four hours, although for ordinary purposes it is sufficient to use the alarm mechanism once in the stated interval of twenty-four hours.
- I also contemplate the employment of a throw-off lever by which a member of the alarm mechanism may be adjusted out of the path of a rotating finger on the revoluble sleeve of a setting-dial, thus throwing the alarm mechanism out of service while retaining the spring of such mechanism in a woundup condition ready for service again by the simple adjustment of said throw-off lever back to its operative position.

EIGHT-DAY ALARM-CLOCK.
SPECIFICATION forming part of Letters Patent No. 772,165, dated October 11, 1904.
Application filed February 12, 1904. Serial No. 193,250. \No model.)
To all 712720117 7125 may concern.-
Be it known that I, JOHN l IATZINGER, a citizen of the United States, residing in the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and useful Improvements in Eight- Day Alarm-Clocks, of which the following is a specification.
My invention relates to improvements in alarm-clocks of that class wherein the spring of the alarm-striking mechanism may be wound once in eight days or with more or less frequency, as desired, for the purpose of actuating the hammer of an alarm bell or gong at the required period once in every twelve or twenty-four hours of each of a number of days, thus dispensing with the labor of winding the alarm mechanism every day and enabling said alarm mechanism to be used to good advantage in connection with that style of clocks which are wound once in eight days, whereby the clock-train and the alarm mechanism may each be wound at the required intervals of eight days.
In my invention provision is made for automatically releasing the striker of the alarmtrain at the proper hour or fraction thereof at which it is desired to set off the alarm, but an element of the controlling or setting devices of the alarm mechanism is exposed for ready access in order that it may be adjusted easily by hand for the purpose of releasing the alarm-train at any predetermined hour or fraction thereof.
The invention also includes means by which the alarm mechanism may be set or adjusted to release the striker once in every twelve hours instead of once in every twenty-four hours, although for ordinary purposes it is sufficient to use the alarm mechanism once in the stated interval of twenty-four hours.
I also contemplate the employment of a throw-off lever by which a member of the alarm mechanism may be adjusted out of the path of a rotating finger on the revoluble sleeve of a setting-dial, thus throwing the alarm mechanism out of service while retaining the spring of such mechanism in a woundup condition ready for service again by the simple adjustment of said throw-off lever back to its operative position.
Further objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope of the invention will be defined by the annexed claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which like characters of reference are used to indicate corresponding parts in all the figures.
Figure 1 is a front elevation of a portion of a clock, partially broken away and showing my improved alarm mechanism. Fig. 2 is a front elevation of the alarm mechanism, on an enlarged scale, removed from the clockcasing. Fig. 3 is a side elevation of the alarm mechanism shown by Fig. 2. Fig. 4 is a detail sectional elevation, the plane of the section being indicated by the dotted line 4: 4 of Fig. 3. Fig. 5 is a cross-section through the arbors for the hour and minute hands of the clock, showing the alarm-dial and its sleeve for controlling the releasing devices of the alarm-train. Fig. 6 is a detail view of a divided adjustable cam by which the frequency of operation of the alarm-train may be increased or diminished, the dotted lines illustrating an adjusted position of one member of said cam.
To enable others to understand my invention, I have shown it applied to an ordinary form of eight-day clock by Fig. 1 of the drawings. Within the casing Ais installed an ordinary time-train B for driving the arbor a of the minute-hand C and the tubular arbor b of the hour-hand D. The clock may be of the usual or any preferred construction; but as my invention may be used in connection with any style of clock I do not consider it necessary to enter into a detailed description of the construction and mode of operation of the clock mechanism.
An important feature of my alarm mechanism is a revoluble sleeve 5 in one with an alarm-dial 6 and provided with an actuatingfinger 7. The sleeve and the alarm-dial are made rigid one with the other, and they may be made integral, the inner end of said sleeve being split or divided at 8 to give a certain amount of elasticity thereto. The finger 7 may be provided on the sleeve in any suitable way, but, as shown by Fig. 5, the finger is attached to a collar 9, integral with the sleeve at one side of the split portion thereof. Said sleeve is slipped over the tubular arbor b of the hour-hand to have tight frictional engagement With the arbor for rotation therewith; but the alarmdial and the sleeve may be adjusted by hand inorder to vary the position of the actuating-finger with respect to the releasing device of the alarm-train. The sleeve passes through the clock-dial, and the alarmdial is arranged compactly between the clockdial and the hands in order to expose it to convenient access for manipulation by the operator, for which purpose the alarm-dial has a milled edge. As shown by Fig. 1, the hourhand D has a pointy (Z, which extends across the alarm-dial, the exposed face of which is inscribed with numbers and designations to indicate the hours and the fractions thereof.
As shown by Fig. 1, an alarm-train is disposed within the clock-casing, the frame 10 of said train being fastened to said casing. The alarm-train 11 may be of any suitable type adapted to be propelled by a motor-spring 12 on a winding-arbor 13, that passes through the clock-dial. A pinion-shaft 1 1 of the alarmtrain carries an anchor-wheel or pallet-wheel 15, and a pinion 16 on the pinion-shaft 1st is driven by a gear 17 of the train, said gear being provided with a laterally-extending stud 0r pin 18. In the path of rotation of this pin or stud is the beveled face 19 of a locking-lever 20, the latter being disposed in an upright position on one side of the alarm-train and being made fast with a rock-shaft 21, that is mounted in the lower part of the frame 10. This lever is normally impelled toward the path of the rotating stud 18 by a spring 22, coiled around the shaft 21, said spring being anchored at one end on the frame 10 and acting at its other end against the shaft 21 or the lever 20. The pallet-wheel is provided with a stud 23, which rotates therewith and projects toward the lever 20, and said lever is equippedwith two pins or studs 24: 25, the same being of unequal lengths and projecting in opposite directions from the respective sides of the lever. The short stud 24 extends toward the pallet-wheel 15, and normally it lies in the path of the rotating stud 23 on said wheel, so that the two studs 23 2t have cooperative engagement when the parts are at rest in order that the stud and the lever may lock the alarm-train from movement under the energy of the motor-spring 12.
The pallet-wheel 15 is engaged by an anchor 0r pallet 26, fast with a striker-shaft 27, mounted in the frame 10, and secured firmly to this striker-shaft is a hammer-arm 28, the latter being actuated by the shaft and the anchor when the teeth of the revoluble pallet-wheel 15 impart vibratory movement to the anchor on the release of the alarm-train from the restraint of the stud 24, that is carried by the locking-lever 20. This hammer-arm strikes a bell or gong, (indicated by dotted lines at 29 in Fig. 1,) said gong being located, preferably, outside of the clock-casing, and to enable the hammer to strike the gong it passes through the clock-casing, although it should be understood that the particular location of the gong and the arrangement of the hammer is not material.
The long stud or arm of the locking-lever projects into the path of a controllingcam, (shown by Figs. 2, 3, and 6 of the drawings,) said cam consisting of complemental members 30 31, clamped adjustably one to the other and each provided with a plurality of projections 82, herein shown as three in number, although this may be varied. The clamping means are embodied in the form of a screw 33, which passes through a slot 3 1 in one member and is threaded into the other member, although the particular clamping device is not essential. In Figs. 3 and 6 the members of the cam are shown as being adjusted to corresponding positions, wherein the three projections 32 of one member register with the similar projections of the other member for making the two members serve as one in releasing the alarm-train once in twenty-four hours for three successive days; but in case it is desired to release the alarmtrain twice in twenty-four hours the clamping-screw may be slackened, one member of the cam turned to a position wherein the projections thereof alternate with those of the other member, and the clamp retightened to make the members turn as one part, thus affording means by which the stud or arm and the lever 20 may be operated at intervals of twelve hours. The cam has a sleeve 35 made fast with one of its members, on which sleeve is adapted to be adjusted the other cam member, and said sleeve carries a ratchet 36, the latter being one element or member of a stepby-step feed device that is actuated by the rotating finger 7 of the alarm-dial sleeve 5. The cam and its sleeve 35 are mounted idly on a short post 37, projecting from the frame 10. \Vith the ratchet 36 cooperates a beveled lip 38 of a spring-pawl 39, said lip and pawl being shown more clearly by Fig. 3 and said pawl being compactly arranged against one arm of an angular feed-lever lO. Said springpawl is fastened to the lever, and the lip of the pawl plays in a slotted or forked end 41 of the lever, said forked end of the lever being clearly shown by Fig. 2, thus bringing an arm of the lever and the pawl into overlapping relation to the ratchet, as in Fig. 2, so as to make the lip 38 assume a position wherein it will engage with the teeth of the ratchet successively on the repeated move- IIO ments of the lever. Said lever is fulcrumed at its knee by mounting it loosely on an end portion of the rock-shaft 21, and it is normally drawn in one direction by a spring 42, shown as a coiled spring anchored on the frame 10, the movement of the lever under the energy of the spring being arrested by a stop 43 on said frame. One arm of the angular feed-lever is arranged in the path of the finger 7 which rotates with the tubular arbor of the hourhand, and at the proper time this finger engages with said arm of the feed-lever in a way to move it against the tension of the spring 42. This movement of the lever turns it to make the spring-pawl travel with the other arm, so that the lip 38 will ride over one tooth of the ratchet and snap into engagement therewith. The spring 42 pulls said lever and the 5m back to the position where the stop 43 arrests the travel of thelever, thus making the pawl turn the ratchet one tooth. Assuming that the cam is adjusted to operate the locking-lever once in twenty-four hours, the feed-pawl turns the ratchet and the cam at the end of twelve hours to a position where on the first operation the long stud or arm 25 will lie between two of the projections 32 of said cam, thus allowing the alarm-train to remain at rest; but on the next rotation of the hour-hand, the sleeve 5, and the finger 7 the latter again moves the feed-lever for the pawl to again turn the ratchet and the cam, thus bringing one projection 32 of said cam against the lever 20, whereby the latter is pressed back against the tension of the spring 22 a sufficient distance to make the stud 24 clear the stud 23 of the pallet-wheel. This releases the alarm-train for the spring 12 to' drive the gear 17 and cause the pallet-wheel to actuate the hammer through the medium of the anchor and the striker-shaft, thereby sounding the alarm. Ordinarily the rotation of the gear 17 when it makes one complete turn will cause the stud 18 of said gear to press the lever back to normal position and interpose the stud 24 in the path of the stud 23 and stop the operation of the alarm-train and the alarm; but to increase the length of operation of the alarm I make the number of teeth in the gear 17 in unequal proportion to the teeth of the pinion 16 and the rest of the gears of the train, whereby on the operation of the alarm the stud 18 will ride at the end of the first revolution of the gear 17 against the end 19 of the lever 20 at a time when the stud 23 of the pallet-wheel is at quite a distance from the stud 24 of the lever, thus allowing the stud 18 to move and ride past the lever 20 before the stud 23 of the pallet reaches the path of the stud 24. This permits the alarm to run for an increased length of time until the gear 17 makes another complete turn, at which time the stud 18 rides against the end 19 of the lever and moves the latter to place its stud 24 in the path of the alarm-train.
which is fulcrumed at 45 on the clock-casing and has one end extended through said casing for access outside of the same. The inner end of this lever 44 has an angular arm 46 arranged to press against that arm of the lever 40 which is in the path of the rotating finger 7. The lever 44 normally occupies a position wherein its arm 46 is free from the feed-lever 40 to allow the latter to be operated at the required time by the rotating finger 7 but to throw the alarm mechanism out of service the operator merely pulls down on the outer end of the lever, thus moving the end 46 against one arm of the feed-lever 40 to shift the latter out of the path of the finger 7, the lever 44 being held in the desired position by any form of catch or fastener. (Not shown.)
To prevent backward movement of the ratchet 36 when it is turned by the pawl 38 and the feed-lever 40, I provide the checkspring 47, which is attached to the frame 10 and engages with a tooth of the ratchet 36 in a way to allow the latter to be turned freely in one direction while holding it against rotation in the opposite direction.
It is evident that the operator can easily turn the alarm-dial 6 to make the pointer (Z indicate any number on said alarm-dial, and this operation of the dial shifts the position of the finger 7, which determines the period of time that the alarm is to be operated.
Changes in the size, proportion, form, and minor details of construction may be made without departing from the spirit of the invention, and I therefore reserve the right to make such alterations as fairly fall within the scope of the invention as defined by the annexed claims.
