CLOCK Filed may 10. 1926 5 Sheets-Sheet 5 Patented Dec. 22, 1931 i UNITED STATES PATENT OFFICE SAMUEL MAZUR, OF BUFFALO, NEW YORK, ASSIGNOR TO THE'SESSIONS CLOCK COM- PANY, OF FORESTVILLE, CONNECTICUT, A CORPORATION 'OF CONNECTICUT CLOCK This invention relates to a clock which strikes the hours and also chimes the four quarters of each hour.

Heretofore clocks having this capacity employed three distinct sources of power, usually springs, one of which furnished the power for the time mechanism, another the power for the hour striking mechanism, and still another for operating the chime mechanism every quarter of an hour. Clocks of this type were therefore quite elaborate and expensive which limited their use to persons of ample means.

It is the object of this invention to provide a clock in which the striking mechanism and the chime mechanism are driven from the same prime mover, in this instance a single spring, thereby not only simplifying the construction and rendering the same more compact, but also materially reducing the cost and the liability of derangement and enabling such clocks to come into more general use.

In the accompanying drawings Figure 1 is a front elevation of a clock embodying an approved form of my invention and showing the parts in the position which they occupy when the time mechanism only is in operation.

The main frame of this clock may be of any suitable construction to support the various working parts but in the preferred construction shown in the drawings, the same comprises upright front and

rear plates

20, 21 which are connected by horizontal rods or posts 22, and an upright auxiliary plate 24 arranged in rear ofplate 21 and connected with the latter by horizontal posts 25. The numeral 26 represents the tubular shaft or socket which carries at its front end the hour hand 27 and which is journaled in a suitable bearing in the front plate in the frame. Turning within this hour shaft 26 and also journaled on the rear plate 21 is a center post or minute shaft 28 which carries at its front end the minute hand 29 of the clock. Motion for driving the hour and minute shafts 2G and 28 is derived from the main or time spring 30 and 's transmitted to these s 1 ""s for turning the minute shaft twelve times duri one rotation of the hour share, the means for this purpose being well known and consistingenerally of winding gear wheel 31 oneratively connecteo with the nrin or time sprin a gear piniOn Q meshing with the winding); gear wheel 31 and connected with a gear wheel 33, a gear 3% secured to the minute shaft 98 and meshing with the rear wheel 33, a gear pinion secured to the minute shaft and meshing with a gear wheel 36, ant

These means which will now he n itioned but oescribed more fully iatei. on consint a shifting ii! secur-ed to the rear on .i of the minute sh so as to turn therewith once per hour; a tappet or star wheel 1 iounted on the minute shaft and having three tappets or short teeth 4f) a .d a lore tappet or teeth .31 arranged equidistant .ro-uud the axis of the minute shai t on the di tie-rent quarters tlnreof; a striking; snail 52 arranged on the tub or hour sha t and havinej twelve W h COTFQ spend to twelve hours of the da and are ranged successivelv nearer to tl a:.' shaft m l ing with t turningabout nteshaft and of this hour 3 {1X18 of th l vular hour shat in Fig. 6; and a gear wheel 54; secured to the front end of the intermediate son "5 so as to turn with he goers 36 and 2-37 s.

from the main spring 57 to the main sh 1s so organized that a greater in' nh oi turns are obtained for o -ieratin the striking and chime mechanism than are usually obtained for operating the striln mecha only, and for this purpose this speed in easing train of gearing; preferaliily comprises a main. or winding gear wheel 58 connectedv with the main spring 57 and in shine; with a gear pinion 59, and awiieel (30 connected with the pinion 59 and meshing with a near pinion 61 on the main driving haft shown in l, 2, and at. i. pose of retarding the motion of th s gears under the action of the main spring; 5'7, a retarding or brake device is provided which preferably consists of a gear wheel (32 oonnected with the pinion 61 and meshing; with a rear pinion G3, a near wheel Gel: councied with the pinion 63 and meshing with a rear pinion 65 a gear wheel 66 connected with the pinion 65 and meshing with a gear pinion 67, and a rotary fly or fan blade 68 connected. with the pinion (37 and adapted to produce a resistance when rotating in the air.

The gear pinion 63 and gear whee] (3+? are mounted on lifting: shaft 69 which jo rnaled in the main frame and which forms parts of the mechanism for operating the chimes and the strokes of the clock.

l Vhen the chime and strikingmechanism are not in operation the main spring 57 is prevented from turning the shaft 69 and the parts geared therewith, this beine: acconinlished in the present case by a locking; disk 70 secured to the shaft 69, and a vertically swinging lockinn: arm 71 having a lock ng finger 72 adapted to engage with one or the other of two notches 73 formed in the pe riphery of the locking; disk 70, as shown by dotted lines in Fig. 11. Upon raisino; the locking arm 71 the disk 70 is r leased and the mechanism geared to the shaft 9 is no mitted to operate as will presently aopea'z'. The lifting of the lockino; arm 7 is oft-acted by a lifting; shaft 74!: to which it is connected and which is journaled on the main frame, a lifting: arm 75 connected w th the l ftinoi shaft and provided with a lifting iii ,ror 76, a controlling rock shaft 77 journalcd on the main frame and provided with a COl'li'lVflllTlfZ' arm 78 adapted to engage with the underdo of the lifting linger 76 and lift the some and a tappet arm 79 secured at its upper end .ntermediate lover aivoted on the main frame to-the controllingrock shaft 77 and provided at its lower end with a laterally projectingj mitting the spring. 57 to turn the shaft 69 and.

the parts geared therewith. Atv this time however the shaft 69 is only permitted to turn for a short time to put the mechanism in warning condition preparatory to actually sounding the chimes alone. at the first, second and third quarters of the hour, or sounding the chimes four times and following the same with the sounding of thestrike at the end of each hour.

This warning. control is effected in the usual and well known manner by a warning pin 81 on the gear wheel66 which is] engaged by a warning stop arm 82 on the controlling. shaft 77 When therefore, the locking arm 71 is released from the locking disk 7 O the warning arm 82 at the same time moves across the path of he warning pin 81 whereby the gearing. is only permitted to advance far enough to carry the respective notch 73 of the locking disk out of register from the ringing 72 of the locking lever. When therefore the respective tooth of the star wheel again clears the tappet arm the latter can swing backwardly for disengaging the warning arm 82 to release the warning pin and permit the train of gearing associated therewith to advance as far as required, because at this time the respective locking notch notch 7 3 has moved forwardly out of register with the locking lug 72.

inasmuch as the locking disk at times is obliged to makeone or more complete rotations in order to properly sound the chimes and strike the hour, means are provided for preventing the locking arm for re-engaging a notch 7 until after the required number of quarter chimes and hour strikes have been given. This it accomplished by means which operate to hold the locking arm 71 out'of operative engagement as as required and these inc-ans, in the present device comprise a trip arm 83 connected with the controlling shaft 7 7, detent arm 8 1 which performsan' additional function to he described later on, 1H- 1' Ll I01 inc present purpose is pivoted onthe 1 frame and engaged by the trip arm, an

and having a lower arm 86 adapted to be engaged by the detentarm 84, a cam arm 87 pi oted on the main frame and adapted'to be engaged by the upper arm 88 of the intermediate lever, and a cam- 89 formed in the lower end of said cam arm and adapted to control no. engagement of the locking arm 71 with the notches of the locking disk 70.

emmas The intermediatexlever 86, 88has a weight 90 which operatesto turn the same by gravity in the direction for engaging its lower arm. 86 with the detent arm. When therefore the locking arm 71 is raised by the star wheel to release the locking disk the cam 89 holds the locking arm in its inoperative position until the detent arm returns to its normal position, as will be described later on, thereby insuring turning ofthe locking disk and the-parts associated therewith the requisite extent.

When the detent-arm 84 returns to its normal position after the chime and stroke operations h'avebeen effected, the cam 89 is moved by gravityjn' the direction for permitting. the locking arm 71 to reengage the locking.

disk 70 and stop the counting device associated with the chime and striking mechanisms and the sounding operations of the latter.

If desired, an auxiliary stop may be provided for directly arresting. the rotation of the fanblades 68,. this heingfaccomplished by a: stop arm 91 arranged on the shaft 92 which carries the fan gear wheel 66 and a shoulder 98 arranged onthe cam arm 87 and movable out of the path of. the stop arm 91 to permit the fan to turn when the chiming and striking mechanismsare released for operation a-ndto move into the path and arrest the rotation of said stop arm when the rocking arm 71 is re-engaged with the locking disk and'stop the operation of the chiming and striking 'mechanisms.

These parts of this invention whereby each quarter hour and each hour is sounded are constructed as follows Slidable lengthwise on the main shaft 56 between the rear frame plate 21 and the auxiliary frame plate 24is a chime drum which may be variously constructed but which as shown in thedrawings, see particularly Figs. 2, 5 and 7, comprises a hub 94. mounted on the shaft: 56 so as to be capable of sliding lengthwise and also at times turning therewith and at times held against turning with the same, two'disks 95 and 96 carried by said hub, and four annular rows of tappets or pins 97, 98,99 and 100 carried by said disks, the two

rows

97 and 98 being preferably mounted on opposite sides of. the front disk and the two rows 99 and 100 being arranged onopposite sides of the rear disk 96.

In the rear of the chime drum is arranged a striking disk 101 which is provided on its front side with an annular row of ten striking pins *or tappets 201, and which is the main shaft 56, see i 7. On its front side the striking dish DTOVlClGCl with an annular row of tappets On its rear end the hub oil. the chime dru is provided with an annular row of coupliiig openin s 20a whici are on a pitch line mare/spending to the positions of the coupling opening 102 in the striking disk so that the chime drum can be coupled vith the main shaft upon moving the chime drum ha 'wardly when ever one of its coupling oaenings 20 1 in line with the pin 103, at which time the latter will enter the respective opening 20% in the chime drum and couple the same with the shaft so that these members turn as shown in Fig. 111 the foremost pos' tion of the drum, the same is uncoupled fro: the main shaft :36, as shown in '4', and at this time the chime drum is locked. o i turning by a locl ziug pin 105 projecting rcarwardly from rear "frame plate and engaging with a locking opening 106 in the chime drum. ll hcn drum moved rwardly it is first disengaged from the look ing pin 105 so that it is free and then the same is interhiclie-rl with the coupling pin 103 to connect wnh the rain shaft 56. l'hc forward movement of both the chime cram and the strikin disk limited by nient ol' the front side of the urum a shoulder 10'? on the locking pin 105, and "his drum and the striling dis; are yield ingly held in this "foremost position by a spring 108 surrounding the shaft between the rear side of the striking disk and the collar 10-l. The rear.vard movement of the chime drum and the striking disk is el'iected by means of a rock shaft 105;) journaled r the rear plate of the main i arm 110 engaging with the trout drum rad an inner arm 111 en i the cam 1'? on the main driving sl' 1..

The cam ll is so constructed and positioned that during the first fifteen mimites the hour the same shifts the chime drum bacl-2- \vardly into engagement with the coupling pin 103 so to cause the drum to turn with this shalt. As soon as the drum i far enough to ca" y its locking opeuz.

of ro ter with the locl'i g pin, then the salient are of the cam l? clears the arm 131, but the front of the drum at this time is riding on the rear end of the lacking pin 105, the drum and .13.; disk cannot again move forwardly under the pres sure of the spring 108 until the 6 made a complete etation and the lo opening 100 has again come into with the pin 10?).

By this means the drum will be locked against rotation a tlu: cl'iiming of the rour (pier of each hour and during the hour. The chime drum leased by the cam 17 during t. 1 ol" the new hour.

be locked against turning only in one position, any accidental displacement of the drum on the driving shaft will be automatically corrected so that the drum will always start oil at the same point and thus insure unifo unity in the sounding ot the chimes of the four quarters and the strokes of the hours.

The several annular rows of tappets on the chiming drum and striking dish are adapted to engage successively with the upper arms of trip or bell levers 112, 113, 114;, 115, 116 respectively, which are mounted to turn about a longitudinal horizontal rod 117. lhe lower arms of the hell or trip levers 112, 113, 11 1 and 11.5 associated with the tappets of the chime drum are provided with pins 118 engaging with the upper arms of elbow shaped hammer levers 119, 120, 121, 122 which are pivoted co-axially on a horizontal longitudinal rod 123, each of which has its lower arm connected by a hammer rod 124 with a hamm r head 125 which is adapted to strike a hell rod 126 so as to produce the ell'ect of a chime or gong. Each of the bell rods mounted at one end on a stand 127 which in turn is supported on the casing of the clock in any desired manner. As the drum rotates, the bell tappets in each of its rows turn the respective trip lever in the direction for raising the companion hammer, and as each bell tappetclears the respective trip lever, the corresponding hammer drops and delivers a blow against the bell. rod below the same. he tappets of the several rows on the chime drum are so arranged that bell rods of different tones are struck in the proper se quence to produce the effect of ringing chimes in a manner well known in this art.

In order to avoid increasing the nmnbcr of hell rods beyond those required for the chimes, one of the chime rods, preferably the foremost one is also utilized as the bell for striking or sounding the hours. This is accomplished by providing a yoke 128 which extends lengthwise ol the several trip levers and is adapted to be enc ed by a pin 120 or. the lower arm of the striking trip lever, and the front end of this yoke being connected with the foremost hell hammer elbow level; and the rear end of the yoke being pivoted on the auxiliary frame plate, as shown in Figs. 2 and 5.

During the first quarter of each hour the cam 17 pushes the chimes drum backwardly so s to become interlocked and turn with the main shaft 56 without shi ting the ta pets thereof beyond their respective hell trio levers, but at the same time the chime disk is moved backwardly so that its bell tanpcts clear the striking bell lever 116. It tollopn frou'i this that the drum and striking dish will turn in unison but only the chimes levers will he tripped by the chimes tappets and ause their respective bell rods to sound while the tappets of the striking; disk will witht rotate idly without actuating the bell striking lever.

Immediately after the ringing of the fourth quarter of the chimes rods has been completed by the completion of a rotation of the main shaft, the chimes drum is moved forward"? and locked against further turning but the striking disk continues its rotation and as its bell tappets are now in line armcst bell trip lever 116, the latter is tripped and its motion isltransmitted by the yoke 128 to the foremost bell lever 119 so that the hell or gong of the latter is now 1 structed as follows The

numerals

130 and 131 represent two counting gear racks which are preferably in the form of segments arranged side by side and axially in line and having teeth of ratchet form. The rack 130 is the main rack and works primarily in connection with the. striking mechanism and. the rack 131 is the auxiliary rack which works primarily in connection with the chime mechanism. The main rack is comparatively long and. has over twelve teeth, preferablysixteen, the lower twelve 1532 serving as counting teeth while the teeth 133 above the counting teeth, serve solely as lifting teeth. The auxiliary rack 131113.5- in excess of four teeth, preferably six in number, the lowermost four 134 of which serve as counting teeth while those teeth 135 arranged above the counting teeth 134 serve lifting teeth. The teeth of the main rack are comparatively long and those of the auxiliary rack comparatively short. The main gear rack is provided with a snail arm 136 i'rhich rocks therewith and is provided with a gage finger 137 adapted to engage one or another of the steps of the main or striking snail 52. The auxiliary gear rack is provid ed with a snail arm138, which rocks with the same and is provided. with a gage, finger 139 adapted to engage with one or another of the steps of the auxiliary snail 53. 7

At the free or upper end of the detent arm 84 the same is provided with main and

auxiliary detent pawls

240, 140 see Figs. 16-19, the latter being short and adapted to engage with r the teeth of the auxiliary rack and the former same are lifted in accordance with the position of the main and auxiliary snails, and

finally engage with the lower ends of these racks and hold the same in their highest or foremost position after a chiming operation has been, completed at the end of the first, second and third quarters of each hour, and the rhimin g and striking operations have been completed at the end of each hour.

Means are provided whereby the gear racks after being released and moved backwardly in accordance with their respective snails, are r-sed step by step until the same reach highest or foremost position. The means for this purpose comprise a lifter which engages with the teeth of the gear racks. This lifter has the form of a rotary gear pinion141 mounted on the lifting shaft (59 and provided with teeth 142, 143 adapted to engage with the teeth of the main and auxiliary gear racks respectively. As the pitch of the teeth on the main gear rack is relatively of larger diameterthan the pitch of the teeth of the auxiliary gear rack, the pitch diameter of the teeth 142 of the lifting pinion engaging with the main gear rack is smaller than the pitch diameter of the teeth 143 of the lifting pinion engaging with the teeth of the auxiliary gear rack, thereby causing the auxiliary gear rack-to always move slightly in. advance of the main gear rack during each stepof the lifting operation, and thereby easing this operation of lifting the gear racks.

As shown in Fig. 1,.the detent arm 84 has dropped to its innermost positionin which its

pawls

240, 140 engage with the lower ends of both-the main and auxiliary gear racks 130,

131 respectively, at which time the chiming and striking mechanism is at rest. The detent arm84 is limited in its movement in this direction by engaging a stop 144 on the main frame.

Assuming that the time mechanism of the clock arrives at the first quarter past an hour, the operation of the chime mechanism will be as follows Upon reaching the first quarter of an hour, the first short tooth or tappet 48 of the star wheel will en the lug 80 of the tappet arm 79 and turn the trip arms in the direction for releasing the locking arm 71 from the locking disk 70 and moving the auxiliary detent pawl 140 far enough to disengage the same from the lowerend of the auxiliary counting gear rack 131 but not far enough to disengage the pawl 240 from the lower end of the main counting gear rack, thereby permitting the auxiliary coimtingrackto drop until its gage finger 139 engages the highest face of the auxiliary or chime snail and also permitting the main shaft 56 and the lifting pinion 141 to turn. The instantthis occurs, the chime drum will be turned far enough to produce four strokes on the hell or chime rods and then be stopped by the stop arm 71 engaging with the next notch 7 3 of the locking disk 70. The stop arm 71 is permitted to thus engage this locking disk due to the fact that the lifter 141 during its first half rotation upon being released engages one of its auxiliary lifting teeth or pins 143 with an adjacent tooth of the auxiliary counting rack and raises the latter one space, tooth or step so that the detent pawl 14-0 can again drop fully back into engagement with the lower end of the auxiliary rack and prevent the latter from falling back when the litter is disengaged from the auxiliary rack. As the detent arm 84: moves back fully and engages its pawl. with the lower end of the auxiliary rack, the detent arm also permits the weight 90 to turn the

intermediate levers

86, 88, in the direction for permitting the cam arm 87 to swing back and cause its cam slot 89 to lower the lifting wire and the locking arm 71 to drop its finger 7 into the next notch 73 of the locking disk, thereby arresting the operation of the chime mechanism after the san e has sounded the chimes but once. While the litter is turning and engaging the adja cent tooth of the auxiliary rack for raising the same one step, one of the main pins 142 of the lifter also engages the adjacent tooth of the main rack and lifts the same, but as the main detent pawl 2&0 only engages the lower end of the main rack at this time the latter is raised idly and simply drops back into its normal position after the lifter lets go of it. This idle motion is imparted to the main rack during all subsequent operations on the same by the lifter whenever the main rack is in its highest position and the litter is acting on the auxiliary rack for raising the same.

At the end of the second quarter hour or half hour the second tappet 49 of the star wheel again releases the locking arm 71 from the locking disk 7 0 and the detent pawl 141-0 from the lower end of the auxiliary rack, and permits the latter to drop two steps because the gage finger 189 at this time is arrested by the second highest face of the auxiliary snail. It therefore requires two operations of the teeth or pins 14:3 of the litter on the teeth of the auxiliary rack for raising the latter two steps before the same has been again returned to its highest or home position where the auxiliary (letent pawl 140 can again drop back fully into engagementwith the lower end of the auxiliary gear rack and stop the operation oi? the train of gearing forming part of the bell mechanism. As the auxiliary rack is raised a step the detent arm is moved outwardly su'liicien tly by the tooth oi the auxiliary rack engaging with the any iliary pawl 140 but the latter engages under-- neath each succeeding tooth of the auxiliary rack as the latter is raised step by step, during the turning of the litter 141 and therefore acts like a detent ratchet to hold the auxiliary rack at the end of every upward step which is gained.

Vhile this gearing is thus in operation for two steps ot the auxiliary counting racl-t, the chime drum turned. t ro and causes the chime or hell rods to sound the first and second quarters or the halt of the hour and then come to rest.

In like manner the bell gearing will be re leased by the third short tappet 50, at the end of the third quarter of the hour and the auxiliary counting racl: ill be permitted to drop three spaces by engagement oi its linger 139 with the third highest face 0 auxiliary snail, thereby IIQCGSSlLfilJlZlg' tnree lifting steps or operations Oil the litter 14-1 on the auxiliary rack before the latte is again restored to its normal or home position which the detent pawl 141:0 again engages fully with its lower end and the operati on of the bell mechanism has been arrested. During these three lifting steps on the auxiliary rack, the chime drun turns three steps and causes the chimes to sound thrice denoting the third quarter of the hour and then stops.

At the end of the first hour the long fourth tooth or tappet 51 of the star wheol eugages the lug oi? the tappetarm 79 and turns the trip arms a greater extent than that which effected by the short eth 4:8, 49, 50 there by releasing the train 01 bell operating gearing and moving not only the auxiliary detent pawl. l l0 from underneath the au; iliary counting raclr but also moving the main detent pawl 2410 from underneath the main counting raclr, as shown in Figs. 3 and 1f), Yvhen this occurs the auxiliary rack drops tour spaces until its gage finger 130 engages with the lowest quarter face (if the auxiliary snail which is i'nored. into this position by the time mechanism, and the mai u counting rack drops one step, its downward movement being arrested a is time by engagement of its gage linger 137 with the highest ht the twelve faces on the main snail. which is turned into this position by the time mechanism.

After the detent pawls M0 and 24.0 have been thus disengaged from the aioziliary and main racks by the long tooth. 51 of the star wheel and this tooth again clears the tappet arm 79 of the trip arms during its continued rotation, the detent arm S-l mores forwardly or inwardly but new only engages its main pawl 24-0 with the teeth of the main raclr while the auxiliary pawl l-l0 is held out of engagement with the teeth of the an u raclt, as shown in Fig. 18. As the litter new turns with the bell mechanism, the lirst tooth 14-2 engaging with the teeth of the main rack raises the same one space and then the main detentpawl 24:0 passes underneath the lower end of this rack and olds it in its highest position. \Vhile the latter thus operating on the main rack, the same does not operate on the auxiliary rack because the teeth of the auxiliary rack and the auxiliary pawl 140 are too short to permit of engagement for this purpose,- as shown in Fig. 18, and the auxiliary rack therefore remains at rest in its lowermost position while the main rack is be ing raised by the lifter and held by the main pawl 240. While the main gear rack is being lifted by the lifting pinion or wheel, the latter also operates on the teeth of the auxiliary rack and raises the same but since the auxiliary pawl 140 does not engage the auxiliary rack at this time, this movement of the latter is idle and the same drops back after each lifting operation. The instant how- 1' ever, that the main rack has reached its hi ghest position and the main pawl has moved fully in its innermost position underneath the main rack, then the auxiliary pawl 1-10 is permitted to engage with the teeth of the auxiliary'rack, as shown in Fig. 17. As

the lifter new raises the auxiliary rack, the same is caught at the end of each step by the detent pawl 1 10 and prevented from falling back and after the same has been raised four steps to its highest position, the detent arm moves forwardly into its foremost position in which both the main and auxiliary pawls 2 1-0, 140 engage with the lower ends of the main and auxiliary racks. During the one step which the main rack isbeing raised, the

bell mechanism operates to chime the first quarter, during the first upward step of the H auxiliary rack the chimes are operated for the second quarter, during the second upward step of the auxiliary rack the chimes are operated for the third qu'arter,-during the third upward step of theauxlliary rack the chimes are operated for the fourth quarter, and during the last or fourth upward step of the auxiliary rack the striking mechanism is operated to strike one oclock.. For this pur pose the timing, chiming andstriking mechanisms are so timed that the timing drum remains coupled with the main shaft 56 from a period in advance of the first quarter until the end of the hour so as to chime each of the four quarters and immediately after the fourth chime at the end of the hour has been completed, the opening 106 in the drum registers with the pm 105, thereby causing the drum to be uncoupled from the shaft 56 and discontinue the chimes and then bringing the striking disk into its forward position, whereby the same can strike the hour.

After the clock strikes one and some time before reaching quarter after one, the constantly rotating cam 47 pushes the chime drum and striking disk backward from the position shown in Fig. 7 to a position shown in Fig. 5, whereby the chime drum is cou pled with the main shaft 56 but the striking disk is moved out of operative relation to the striking lever 116. The result is that at the end of the first quarter of the hour the chimes because it is held back by the drum riding on the rear end of the pin 105 until the four quarters of the hour have been completed, and then the drum is again pressed forward by the spring 108 to lock the same against turning and bring thestriking disk into position for operating thestriking lever 116, as shown in Fig. 7. The operation of chiming the first, second and third quarters of each hour are repeated continuously in the manner just described with reference to the chiming, before the striking of one oclock.

When the clock reaches two o=clock, the long tappet 51 again turns the 'detent arm 84 outwardly its fullextent so as to permit both the main and auxiliary counting racks to drop, the auxiliary rack dropping four steps as is usual at the end of each hour, but the main rack dropping two steps, inasmuch as the main snail at this time presents its next lower face to the gage finger 137 of the main rack. As'the lifter 141 begins to turn, the pins 142 of the same successively engage the teeth of the main rack and lift the same two successive steps to its highest position where it is held bythe main detent pawl 240, and

then the auxiliary rack is raised four steps to its highest position and held there bythe auxiliary detent pawl 1&0. The two upward steps of the main rack and the first two upward or return steps of the auxiliary rack are used for counting the four quarter chime A actions, and the last two upward steps of the auxiliary rack are used for counting the two strokes representing two oclock.

As the time reaches three oclock the auxiliary rack drops four steps and the main rack drops'three steps, and subsequently the main rack is fi'rst'lifted three steps to its home position and then the auxiliary rack is lifted to its home position. During this lifting operation, the three upward steps of the main rack and the first upward step of the auxiliary rack are utilized for operating the four quarters of the chimes, and the remaining three upward steps of the auxiliary rack are utilized for operating the striking mechanism three times.

Upon arriving at four oclock the auxiliary rack drops four steps and the main rack also drops four steps. The lifting mechanism now first lifts the main rack four steps and then lifts the auxiliary rack four steps. The four return steps in this instance are utilized to-count the four actions of the chime mechanism for the several quarters, and the four return steps of the auxiliary rack are T utilized. to count the four actions of the mechanism which strikes four oclock.

.it the end of the fifth hour the auxil rac lrops four steps on to the lowest of the snail and the main rack drops five steps on to the fifth face of the main snail. As the main and auxiliary racks are successively raised step by step thereafter. the first four upward or return steps of the main rack are utilized for counting the tour chiming actions corresponding to the four quarters of the hour, and the fifth or upward step of the main rack and the four upward or return steps of the auxiliary rack are utilized to count the five striking actions corresponding to five oclock.

At the completion of each additional hour the main counting rack drops one step turther and therefore has to be lifted a correspondingly increased number of steps in order to return the same to its home position by means of the lifter, but the auxiliary racl: at the end of each hour always drops four steps representing the tour chiming operations at the four quarters of the hour. lira the main rack progressively increases the extent of its drop and therefore also increases the extent of its return movement in the same measure, the first four lifting steps of the main rack are always taken out to operate the four quarters of the chime mechanism and the remaining litting' steps of the main rack are added to the four litting steps of the aut iliary rack to complete the counts required for striking a particular hour. In other words, whci'i the time is four oclocl: or more, then the tour counts taken oil from the advancing end of the main rack for operating the chiming mechanism are always added by the auxiliary rack to the trailing end of the main rack so that the combined count equals the tour chime operations and the strokes of the particular hour. t is only when the time or the hour is below tour ocloclc that the tour chiming steps are counted, partly on the main rack and partly on the auxiliary rack, as previously described. At all other hours the chiming is always counted wholly on the main rack and the striking is counted partly on the main racl: and then finished on the auxiliary rack.

In Fig. 1 the main and auxiliary racks are both raised to their highest position, the main snail stands in a poi'ition in which the same presents its ninth space to the main gage finger 137 and therefore would cause the striking mechanism to announce nine oclock, and the auxiliary snail is in the position for arresting the auxiliary gage finger so that the chimes will play the quarter.

Figure 3 shows the main racl: dropped to the twelve oclock striking position on the main snail and the auxiliary rack dropped to the first quarter chiming position on the auxiliary snail.

The parts are shown in Fig. 14 in the position in which the auxiliary rack h 011 dropped to the four quarter chiming position on the lowestface of the an iary snail, and the main rack has been droppec to the seven ocloclr strilfng position on the main snail, but has already been raised six steps, our of which were used for the four cnin'ie quarters, and two for striking, leaving one more on the main rac and tour on the auxiliary rack for striking seven ocloclr.

In Fig. 15 the parts a e wn in the position in. which the aux ry racl: 1 been drotjipcd to the tour ouarac f ch tion on the auxiliary snail aud the oil is shown in a position in which it h eviously permitted the main racl d twelve oclock striking position but the iillljtl has already lifted the main rach five steps. oi which four were utilized to count the tour quarter actions of the chiming mechanism and the I -I'll ,jQiVOtl to count the first stroke of twelve oclock leaving tie remaining seven steps on the main rack and the four steps on the auxiliary racl: to complete the remaining eleven counts for twelve ocloclr.

From. the iioregoing desmxiption in connection with the accompanying drawi it will now be apparent that this inviition provides a tour quarter chimiz. and hourly striking clock in whic the same motor such as a spring or the like, serves to op rate both. the chiming mechanism and the striking mechanism.

By this means the cost of a clock which chimes the four quarters of each hour and strikes each hour, materially reduced. Moreover the cost of manutacturin the clock and ocnse of repairins the 11110 is les- H more com- 7 the same require,- wiinling of but two springs instead of three the mine can be taken care of more ea ii? desired a separate striking hell rod may he cmploycd which is struck by 21 sep: rate bell harnmer, having a hammer head 225 and a rod 224i connecting the Same with the pivoted yoke 128 which is operated by the bell lever 116 of the striking mechanism as shown by dotted lines in F 13, but in such modified construction-the longitudinal bar ol? yolre 128 not connected with the foremost chiming bell lever 119.
