Specification of Letters Patent.

' Patented Feb. 15, 1916.

Application filed February 17, 1913. Serial No. 749,022.

'0 (ZZZ 101mm it 2;: 1y concern Be it known that I, FRANK GATES Forum, a citizen of the Commonwealth of Australia residing at Glenmona, WVarrigal Road, Oakleigh, near Melbourne, in the State of Victoria and said Commonwealth, haveinvented new and useful Improvements in and Relating to Alarm-Clocks, of which the following is a specification.

This invention relates to devices for sounding alarm bells and the like and particularly to such devices of the kind in which at a single setting of the operating mechanism for a pre-determined time or times any number of alarms may be given during the complete travel of the hour hand once around the dial of a clock. In devices of this kind as heretofore proposed, the alarm for any setting could only be sounded for a predetermined interval.

The object of the present invention is to provide an improved alarm device of the above kind whereby alarms of varying duration can be given at will.

With this objectin view the invention consists in providing means whereby any number of alarms may be set at a single operation in such manner that a short ring, a continuous ring. or a repeat ring may be given for each alarm. In the case of a continuous signal it would. of course, be necessary to rewind the alarm train before a further signal. could be given.

The invention also consists in the novel features as hereinafter more particularly described and claimed.

A clock fitted with a reminder alarm constructed according to the present invention is particularly useful to commercial and other business men as well as for domestic, theatrical. scholastic, or other purposes, where an alarm or signal is required at predetermined intervals and during a period of twelve hours which period comprises the complete revolution of the hour hand arbor of an ordinary clock.

Furthcn'more the device according to the present invention may be fitted to any clock of ordinal-v construction, or clocks may be constructed specially to suit the alarm devices embodied in the present invention.

The accompanying drawings illustrate the present invention embodied in a clock of ord nary construction and in which:

Fig. 26 is also a View illustrating a constructional detail.

Like reference numerals indicate the same i or corresponding parts in all the figures.

According to this invention the face of the clock is of special construction and consists of a ring 1 having two inwardly projecting flanges around the circumference thereof. The inner flange 2 is the larger and is adapted to receive around the inside thereof a disk 3 of suitable material having the clock dial 4; attached thereto.

The inner and outer flanges 2, 5 are provided with a series of slots or holes 6 around the circumference thereof, of a number suflicient to indicate every five minutes of the hours indicated on the dial 4:, thus in a twelve hour dial as illustrated, the ring 1 would be provided with one hundred and forty-four holes 6 as illustrated in F ig. 1 of the drawings. Alternatively, the holes 6 may be distanced at an interval of ten minutes relative to the dial as illustrated in Fig. 2 but it will be readily understood that the number of holes could be confined to any other periods of time and may be indicated as desired. A pin 7 is adapted to pass within each corresponding hole 6 in the flanges 2 5 the pin being provided with an enlarged head 7 similar to an ordinary pin head positioned outside the flange v5. These pins 7 are frictionally held in their normal or inoperative position by ribs 8 formed around the periphcry of the disk 3 which act in the manner of a flat spring, one rib being provided for each pin used.

The disk 3 and the dial 4 are centrally slotted to receive the end of the hands arbor 9 and the dial is indicated by the hours and .ininutes as ordinarily. Around the edge of the minute indicator is a second indicator 10 preferably printed in a different color and which indicates the five or ten minute or longer intervals as required relatively to the period of time indicated on the face of the dial. A ring 11 held tightly in position is provided. to inclose the ribs 8 and this ring is provided with a flange 12 to allow of a better fit against the outer ring 1 carryingthe pins 7 and to allow of the easy movement of the glass 14.

The arbor 9 carries the hands 13 as usual and the glass 14: is also positioned upon the face of the clock, being loosely held by means of the flange 15 formed on the front edge of the cover or case 16. The glass 14 is adapted to be rotated being loosely mounted upon the ring 11 and held in position by the flange 15 above described. The glass is of suitable thickness and is provided on its edge with a groove 17 having parallel faces adapted to receive a mechanism for regi lating the position of the pins or pintles 7. This regulating mechanism consists of a case, the body 18 of which projects outwardly from the glass while its inner end 19 is squared to engage with the parallel faces of the groove 17 and fits flush therein. A pointer 20 projects within the glass along the edge of the ring 11 and is'bent clownwardly at its end at approximately right angles to loosely engage the face of the dial 4 while at the same time. the end of the pointer is in line with the indicator 10 on the face of the dial 1. Lugs or cars 21 are formed on the outer end of the body 18 which rest against the glass face to retain the device in position.

The outer end of the body 18 is formed with a slot to accommodate a small tube 2 1 the outer flange 25 of which is of greater diameter and projects bcyoi'id the body 18, being used as a grip for the fingers when adjusting or cutting out the device. This tube 24rhas a flattened projection 26 projecting through a rectangular or squared slot 27 formed in the inner end of ti e body, the end of the projection being formed with an upwardly projecting hool adapted to engage the head of any of the pins 7. Projecting centrally through the body and the tube 24 is a pin 29 passing through a slot 27 in the inner end of the body 18 and adapted to engage or contact with the pins 7 arranged in and around the ring 1. A small pin 30 passes vertically through the pin 29 to limit the outward movement there of and normally rests against the inner end of the tube 24- within the body of the device, while a spring 31 passes around the pin and the projection 26 and is adapted to re turn it and the pin 29 to their normal or inoperative positions. The projection is formed on one side with a lug 26 adapted to engage one end of the spring 31 the other end of the spring being arranged to bear against the body 18. After the pin 7 has been returned to the normal or inoperative position by the projection. the tube 24 owing to the flange being gripped and pulled outvmrdly against the spring 31 which is consequently broughtinto compression by the lug 26 the spring 81 is freed and returns to the normal or extended posi tion carrying the true and projection 2- to the normal position by acting against he lug 26 on the projection 26.

When setting the alarm for various "aredetermined intervals during a period of twelve or twenty-four hours the setting for the various times throughout the day is com pleted in one operation. This is effected by the device fitted to the glass face 14 of the clock, which device is moved around to the points indicated at 10 corresponding to the time required and the desired pin 7 is then forced inwardly by the pin 29 thereby allowing the inner point to project past the flange 2 of the ring 1.

Should the device be set for one or sevperiods through the day and it is def' l to reset the clock the flanged tube ying he hook 28 is pulled outwardly Jay causes the particular projecting lls T to be moved into the ino aeraosition.

keyed noon the hour hand arbor immediately inside the disk 3, is a radial arm extending to a point near the edge of the ring 1, the outer end 33 of tl radial. arm being bent at right angles to receive the spincle o't rotating roller 3e adapted to direction of the hands arbor rotate in the along the path of the holes 6 through which the pins 7 are adapted to project when set :licating an alarm. A pivoted catch consisting of a bent arm 85 is pivotally mounted at or near its center to a projection 3a of the "adial arm 32. the outer end 37 of the pivoted catch being bent to lie adjacent to the flange 2 of the ring 1, in order that the point suitably tapered may enwith any of the pins 7 which are set to project past the surface of the flange 2 of i. A lat or other spring is led by the radial arm 32 and is adapted make contact with the catch 36 on its 'earward movement the spring not controlthe forward movement in any way. This spring makes contact with the catch tne rear the pivot on any backward movement of the radial arm 32, should the catch engage with a pin 7, and returns the earth to the normal position. As the radial arm rotates with the hour hand arbor and the catch 35 engages a particular projectirg or operative pin 7 in order to permit an alari to be given in the manner hereinto after dc. bed, the roller 3% is adapted to .tly return the particular operapin T o the normal position upon the rotation of the arm 32 and thereis pin ready for resetting. The the bent arm engages another arm 4H pivoted to a boss 42 on the arm which in turn is adapted to age by means of a lip d4; with a trip arm e pivoted at to a boss 46 on the dial arm 32, these arms el and 43 a. movement somewhat similar to a The inner end of the trip arm is at L7 in order to engage with the l of a pivoted controlling arm 4-8. end of this controlling arm 48 is tormec uth a hook or eye #29 passing around the hands arbor and around the collar of the wheel 30 outside the front plate The controlling arm 48 is twisted in or- 60 der to enable it to be pivoted at 51 upon ti o pivot arm fitted to the front plate The upper end 5% of the controlling arm pivotally connected to a sliding rod 55 projecting through the plates 53 and 56 and arranged at approximately right an their normal positions gles to the said controlling arm. At a suitable distance from the plate 56 a collar or button is formed upon or fitted to the guide rod while a second button is fitted to and near the outer end of said rod and rests normally a ainst the inside of the pl ate 526. This latter button is cut away as illustrated in Fig. to form a seat for a spring catch hereinafter referred to. The button 07 is provided at its upper edge with a tapering lip 59 adapted to engage and hold a locking pin 60 fitted to the rocking spindle 51 carrying the trembler or hammer c2 oi? the bell 63. For the purposes of this invention, this locking pin is not in its ordinary position, being placed to the rear of the anchor (A of the alarm escapement wheel 65. and being so placed, the devices embodied in this invention are enabled to control the relase or locking thereof.

A helical spring 66 is fitted around the guide rod and returns the whole of the parts immediately the pivoted catch released. from contact with one of the pins 7.

The combined movements necessary in the operation of the rod arm 48, lever l3 and pivoted catch tend to cause an outward movement to the hour hand arbor owing to the limited movement of the upper cnd 47' of the arm which tends to force the hour hand arbor outwardly but in order to limit any such movement of the roar hand arbor a washer 67 is fixed between the hands of the clock on the minute hand spindle. The washer 67 only allows ot' a slight movement to the hour hand arbor and such movement being limited is not suliicicnt to be of any detriment to the effective operation of the mecha nism.

The wheel working from the minute arbor and controlling the i'novemcnt of the hour hand arbor according to this invention is positioned on the opposite side of J the arbor to that position in an ordinary cloclc, the pinion 50 being also arranged to allow of freedom for the radial arm 32 in its movement around the flange 2 of the ring 1.

A spring catch 68 is adapted to seat upon the ledge formed by the cut away portion of the rear button 58 and projects from a fixed pin or rivet 68 itted to the rear plate. T his spring catch 68 preferably projects upwardly at a slight angle and is formed at its free end with a lug 69 bent over parallel with the llat portion 70 of the rear button 58 toward and approximately in line with the lip on the button That portion of the spring catch (38 formed with the lug 69 is approximately in line with the locking pin 0 on the rocking spindle (31 of the trcmbler 62 when the pin is in the locked position. The free end or slight outward of the pin 60 is provided with a flat face 60 as illustrated in Fig. 10, which is adapted to be engaged by the lug 69 of the spring catch for stopping the alarm train when giving a short signal in the manner hereinbefore described. Normally, that is to say, when the alarm is inoperative, the spring catch 68 does not engage this flat face 60 of the pin 60.

The free end of the locking pin 60 is formed as illustrated in Fig. 10, being pro vided with a flat obliquely disposed face 71 which is adapted to be engaged by the tapered lip 59 of the button 57 when this button and the several other elements of the releasing mechanism are in their normal positions before an alarm is sounded and as illustrated in Figs. 8 10 and 18 of the draw ings. When the parts are in this position the alarm train is locked.

As the spring catch 68 is normally out of contact with the locking pin 60, then when the catch engages one of the operative pins 7, the button 5'? will be disengaged from the locking pin 66 through the medium of the mechanism previously described and the alarm train consequently released to enable a short signal or alarm to be given by the subsequent stopping of the alarm train by the spring catch 68 which is now rendered operative by the means to be shortly ClQSCIllLQL. It should be noted that second and lower locking. pin 89, illustrated in Fig. 16, the control and purpose of which will be hereinafter described with reference to the continuous and repeat alarms, is rendered free to oscillate with the locking pin 60 at this time. i

A locking arm 72 is pivoted intermediate the upper and lower ends to the rear plate 56 at the point 73 and 1s fitted with a distance washer. 'lhepurpose of this arm 72 is to control the operation of the spring catch 68 from the winding spindle of the alarm train as hereinafter described. A spring '75 serves to urg the upper end of the locking arm 72, into engagement with the spring catch 68 and the lower end against a collar 742 of square or otier configuration which 's rigidly nounted upon the winding spindle of the alarm train and is provided for the purpose of regulating the length of the'short ring according to the shape and size of the collar.

The upper end of the arm 72 is bent rearwardly and bears lightly against the rear plate 56, while the lower end is bent inwardly and is adapted to engage the collar 7% at certain periods during the operation of the device at a point a short distance from the edge of the rear plate 56.

The end of the spring catch 68 is formed with a projecting lip 71 which is bent slightly toward the locking pin 6O and is adapted to be engaged by the upper end of the locking arm 72 to urge the spring catch 68 against the pin 60 and thereby retain the latter in the locked position when giving a short signal.

The portion of the locking arm 72 that is adapted to engage the lip 71 is ta iered to a knife edge, the face toward the rear plate 56 however being in the same plane as the remainder of the arm and is perfectly flat. Upon release of the alarm train as above described, the pivoted locking arm 72 is operated, this being effected and controlled by the collar 74 and during this operation, the arm 72 is caused the rear plate 56 out of engagement with the spring catch 68. The precise operation and position of the parts to obtain a short alarm or signal will be hereinafter particularly described.

In order to obtain the continuous and re peat alarms the following means are employed in addition to those described above. The second or lower locking pin 89 referred to above is rigidly secured to the trembler 62. This locking pin 86 is adapted to be re tained in the locked position by means of a pin 87 arranged to be engaged with the lower or free end of the locking pin 89 at certain periods to lock the alarm train as hereinafter described. The pin 87 is carried by a plate 88 'and projects therefrom toward the front of the clock, the plate 88 being slidably mounted upon arranged obliquely thereto as illustrated in Figs. 17 and 18. The plate 88 and the locking pin 89 are approximately in line with each other so as to allow the pin 87 to readily hold. the lower locking pin 89 con trolling the trembler when a repeat signal is being given. The plate 88 is constantly urged in an upward direction under the action of a spring 100 secured at one end to the rear plate 56 and at the other end to a lug 101 provided upon the slidable plate 68. Slots 90 are provided at the upper and lower ends of the plate 68 and through these slots pins 91 are passed. These pins are secured to the rear plate at the inner face thereof illustrated in F 18 and serve as the means upon which the plate 88 can slide at certain periods to effect the release or locking of the alarm train. The enlarged heads of the pins 91 engaging the face of the plate 88 around the slots, retain the plate 86 in position relatively to the rear plate during the sliding movement.

The pin 87 upon the slidable plate 88 is adapted to operate a bent lever 94L at certain periods during the operation of the alarm mechanism as hereinafter described. This lever is pivoted at the bend 95 to the rear plate a ainst which it bears closely while the lower end of one arm of the lever is formed with an eye 96 which is adapted to receive the pin 87, the internal dimensions of the to move across the face of the rear plate 56 and eye being greater than the diameter of the pin 87 so that there is a predetermined amount of play between these two members to permit the necessary relative movement between the pin 87 and the bent lever owing to the fact that the plate 88 and the pin 87 are restrained to move in a straight line, while the end of the lower arm of the bent lever J4 moves in the arc of a circle about the point at which it is pivoted.

T lower arm of the bent lever 94 is raised for a portion of the length at 95 as illustrated in Fig. 21 to permit the plate 88 to passed beneath it, while the upper arm is adapted to be passed between the rear plate and the button 58 at certain periduring the operation of the alarm mechanism to give a continuous or repeat signal as hereinafter described. A pin 92 is also .iounted upon the slidable plate 88 and is adapted to engage the teeth of a wheel 93 on the arbor of one of the wheels of the he train mechanism for controlling the during the repeat signal as here- The pin 92 does not lock 1e :in, but is merely held by the e of the spring 100 against the teeth The slidable plate 88 also a n 98 which projects therefrom the roar of the clock and is adapted to be en iged by means to be shortly des beu for they purpose of ad ustmg the on of the slidable plate 88. The pin 1 arranged to slide in a slot 99 formed the rear plate 58.

In order to regulate and control the length the alarm or signal a regulator 79 is provided which is disposed upon the outer face of the rear plate 56 and pivoted at the point 81. The regulator comprises a cam 80 arranged at the lower end and an arm 79 which is bent and is adapted to project outwardly through a slot 82 formed in the removable cover of the clock casing for manipulation by the operator.

The cam 80 is provided with two worksurfaces 84- and 85 respectively, the surface 84 being a lapted to engage a pin 86 on the locking arm 7 according to the position of the regulator, and consequently remove the loc ing arm 72 from engagement with the sprmg catch 68 and from the collar-upon the winding spindle of the alarm i 7 G, 78 for a purpose to be hereinafter set forth. The pin 98 is adapted to be engaged by both cam surfaces 84 and 85 according to the position of the regulator for the purpose of controlling the position of the pin 87 carried by the slidable plate 88 and also controlling the position and movements of the bent arm 94 as well as efi'ectengagement or disengagement of the pin 9 with or from the toothed wheel 93.

The regulator 7 9 is adapted to be moved by the operator into one of three positions designated a, b, and a in order to control the mechanism to obtain a short signal or alarm, a continuous signal and a repeat signal respectively. When the regulator is moved into the position designated a the mechanism is so controlled by the cam 80 that a short signal can be given. The cam surface 84 then engages the pin 98 upon the slidable plate 88 and moves the latter in a downward direction determined by the guide pins 91 and in a line extending from the top to the bottom of the plate 88. The extent of this downward movement is such that the pin 92 is disengaged from the Wheel 93 of the clockwork train and the pin 87 disengaged from the lower locking pin 89 of the trembler 62. As the movements of the bent lever 94 are controlled by the movements of the slidable plate 88, the upper arm of the bent lever 94 will now be retained below the button 58. At the same time the upper end of the locking arm 72 is urged into contact with the spring catch 68 under the action of the spring 75 as the cam surface 84 of the regulator cam 80 is not in engagement with the pin 86 upon the locking arm 72 as will be clearly understood from Fig. 17 of the drawings, the lower end of the arm 72 simultaneously engaging the collar 7 4 upon the winding spindle of the alarm train as hereinbefore described. Further, it should be noted that the locking pin 60 is locked by the lug 59 of the button 57 this alone preventing operation of the alarm train.

The several parts of the mechanism being in the positions described above for the short signal position, the operation of the device from the dial of the clock for giving the short signal or alarm will now be described.

lVhen the pivoted catch 35 engages one of the projectingpins 7 set to give the desired short signal or alarm at a predetermined time, the intermediate levers, hereinbefore described, which are connected to the catch are actuated and this causes the pivoted arm 48 to be moved into an approximately vertical position as illustrated in chain lines in Fig. 10. Simultaneously with this movement of the arm 48 the rod 55 carrying the buttons 57 and 58 is moved in a direction longitudinally of the rod 55 to the right (see Fig. 10) for a short distance and consequently effects the disengagement of the button 57 from the locking arm 60. Immediately this occurs the trembler 62 and consequently the alarm train is released and the alarm sounded. The collar 74 immediately commences to rotate and continue to rotate slowly during the time that the alarm train is released to give the short signal or alarm.

Assuming the controlling collar 74 to be of square configuration as illustrated, then during rotation, one of the corners engages the lower end of the pivoted locking arm 72 and forces the upper end thereof out of engagement with the spring catch 68. Upon the continued rotation of the collar 7%, as the corner thereof passes the lower end of the arm 72, the latter moves over one of the flat faces of the collar while the upper end of the arm 72 is swung back again into on gagcment with the spring catch 68 under the action of the spring 75.

For a collar of square configuration the arm 72 would be caused to engage the spring catch 68 every quarter of a revolution of the collar and consequently also of the winding spindle of the alarm train. The time occupied during one revolution of the toothed wheel 76 is approximately ninety seconds and the period of ring is limited by the number of sides on the collar 7st, for instance, a five sided collar would give a ring lasting eighteen seconds, while a four sided collar as illustrated would give a ring lasting 22-1; seconds. It is, of course, to be understood that the collars are interchangeable. It should be observed that when the arm 72 is thus moved to engagethe spring catch (38, the button 58 being new in short distance from the rear plate 56, the arm "('2 passes between the rear plate and the button 58 and thrusts against the lip 71 of the spring catch thereupon forcing the latter into engagement with the face 60 of the locking pin 60, the position of the button 58 upon displacement to the right (see Fig. 10) permitting this action to be effected. The locking pin 60 and consequently the alarm train is thus locked again, thereby causing the bell to cease ringing until the pivoted catch 35 engages another operative pin 7.

As soon as the catch 35 has passed the particular projecting pin giving the desired short alarm, the button 57 and rod together with the other cooperating levers hereinbefore described are returned by the spring 66 to their normal position in which the button 57 is again in engagement with the locking pin thereby locking the trembler and alarm train, while the spring catch 68 is moved out of engagement with the flat face 60 of the locking pin 60 by the button 58 upon movement to the left (see Fig. 10) simultaneously with the movement of the button 57, and the spring catch is forced against the rear plate 56. During this operation the arm 72 is swung sli htly away from the spring catch 68 by the pressure exerted upon the spring catch when the button thrusts it toward the rear plate and is returned by the spring into engagement with and at the front of the spring catch, thereby permitting the lug 59 of the button 57 to hold the locking pin 60 until released again by the catch 35 engaging another operative pin 7.

a position a l i hen the regulator is moved by the operator into the position designated 7) for a continuous alarm or signal, the upper end of the locking arm 72 is forced out of the normal position in engagement with the spring catch 68 and the lower end out of engagement with the collar 7%, as hereinbefore described, by the cam surface 8i of the regulator which surface now engages the pin 86 upon the arm 72 (see Fig. 17). Simultaneously with this movement of the rogu later the slidable plate 88 is urged upwardly toward the cam surface under the action of the spring 100. The cam surface 85 is so shaped that the pin 87 is now moved u}- wardly with the plate 88 to such an extent that the pin 87 still does not engage the free end of the locking arm 89. he lower arm of the bent lever 94 is also moved upwardly and causes the upper arm to be moved "ito contact with the button 58 which will be observed is in close contact with the rear plate. The pin 92 is also out of engagement with the toothed wheel 93. ll hcn the parts are in this position the pin 98 on the slidable plate 88 is not in engagement with the am surface 85 of the regulator. A continuous alarm or signal can now be given through the medium of one of the projecting pins 7 engaging with the cat-ch the release of the alarm train being effected in the same manner as for the short alarm or signal. in order that this operation may effected it is pointed out that the locking pin 60 is locked normally that is to say, be fore the alarm is given, by the lip 59 of the utton 57., the parts coo; erating with this locking pin taking up positions exactly the same as the normal positions for the short alarm or signal. As the locking arm 89 is now free, then immediately the locking arm 60 is released the alarm is sounded. For a continuous ring the alarm is sounded. until the spring runs down. In order ther fore to prevent the alarm being stopped when the catch 35 passes th particular oro-jecting pin 7 with which it is in engagement, the bent arm 94: automatically becomes operative the instant the alarm train is released.

immediately the rod and butons and 58 are moved to the right (see the button 58 is moved a short di. tance i the face of the rear plate 56 as pre 7 on lv fron f s described. This enables the upper arm of the bent lever to move farther upwardly to a position between the rear plate am. the button and so pre the re urn of the butten 58 and consequently of the rod 55 and the locking button 57 when the catch 35 passes the particular operatiie pin 7 with .ch it is in engagemt thereb aintaining the locking pin 60 to oscillate with the trembler. This movement of the bent lever 9-1- is adapted to be effected owing to a further slight upward movement of the slidable plate 88 which can take place under the action of the spring 100 until the pin 98 upon the plate 88 engages the cam surface 85 of the regulator. It should be observed that this further movement imparted to the plate 88 is such that the pin 87 still does not engage the lower free end of the locking pin 89. The alarm is therefore permitted to be sounded until the spring runs down completely notwithstanding that the catch has mssed one of the operating pins 7. If a further continuous alarm is to be sounded by a further projecting pin 7 already adjusted for engagement with the catch 35, then, of course, the alarm train would have to be rewound before this can take place. It will, of course, be necessary to remove the upper end of the bent arm from the position between the rear plate and the button 58 in order that the several parts of the mechanism may be returned to their normal positions ready for a further alarm to be given. This may be effected by moving the regulator into the position designated a, so that the pin 87 is then moved in a downward direction with the plate 88 as hereinbefore described and simultaneously draws the upper end of the bent lever 9a to a position .below the button 58, thereby enabling the buttons 57 and and cooperating members to be re turned to their normal position by the spring 66.

Then the regulator is moved by the operator into the position designated a for a repeat signal or alarm, the locking arm 72 is still disengaged from the spring catch 68 and the collar 74 upon the winding spindle of the alarm train by engagement of the cam surface 84 of the regulator with the pin 86 of the locking arm 7 2. In this case also the locking pin 60 and cooperating parts are normally in the same positions as for the short signal or the continuous signal and is adapted to be released in precisely the same manner as in these cases. The slidable plate 88 still remains in the position occupied by it during the inoperative stage for giving the continuous alarm or ring and the pin 87 is out of engagement with the lower end of the locking arm 89. The parts being in this position, the repeat alarm can now be given when the locking pin 0 is released through the medium of the catch 35 and one of the projecting pins 7 in the same manner as in the case of the short and continuous signals. Immediately the button 58 moves to the "ight (see Fig. 10) upon this operation the upper arm of the bent lever 94 moves upwardly between the rear plate and the button 58, but owing to the position of the regulator, it moves a greater distance than for the continuous ring position. The extent of this movement is controlled by the slidable plate 88 which also moves upwardly to such an extent that the pin 87 now engages the free end of the locking arm 89, the pin 98 preferably engaging the cam portion of the regulator. Simultaneously with this movement the pin 92 engages the teeth of the wheel 93 (see Figs. 17 and 18) provided on one of the arbors of the time train, and together act as an escapement device as and Ior the purpose hereinafter described. As the wheel 93 rotates with the time train by reason of the pin 92 engaging one of the teeth thereof and the plate 88 carrying this pin being restrained to move in a predetermined path by the guide pins 91, the plate 88 is drawn downwardly independently of the cam of the regulator to such an extent that the locking pin 87 becomes disengaged from the locking pin 89, the pin 98 it should be noticed being free to move toward the lower end of the slot 99. The alarm is thereby permitted to be given, the locking pin 60 being maintained disengaged from the button 5'; irrespective oi" the engagement of the catch 35 with one oi the projecting pins 7 by the bent lever 9% as hereinbefore described with reference to the sounding of a continuous alarm. As soon as the particular tooth of the wheel 93 passes the pin 92, the plate 88 is urged upwardly under the action of the spring 100, so that the pin 87 again engages the lower end of the locking arm 89 and again locks the alarm train until another tooth of the wheel 93 engaging the pin 92 again draws the plate 88 downwardly. In this manner it will be observed a series of intermittent or repeat rings can be given until the spring runs down.

The withdrawal of the bent arm 9i from the position between the rear plate and the button 58 may be effected in a similar manner as in connection with the sounding of the continuous alarm.

The wheel train and mechanism of the alarm train referred to above consists of the winding spindle and gear wheel carrying the usual spring 77 (see Fig. 17) and also the usual intermediate train of gear wheels 78 for actuating the alarm escapement wheeel 05, which in turn actuates the trembler 62 by means of the U-shaped anchor '64 on the rocking spindle (31 upon release of the locking pin 60.

The supports 102 for the clock (see Fig.

1) are attached to the case 16 in any desired manner but preferably by soldering. They may, however, be secured to a strengthening ring 103 (see Fig. 3) fitted inside the case 16 in any suitable manner. Bearers 104 which project from the edge of the ring 1 are provided and connect with angle arms supports 105 (see Fig. 17) carrying the plates 53 and 56 supporting the clock mechanism. The whole of these parts are clamped in' position by screws 100 (see Fig. 3).

It is to be understood that the mechanicalalarm device according to this invention can be applied to all forms of clocks and the details of construction can be modified as desired without departing from the principle underlying the invention.
