In the following description similar characters of reference indicate like parts in the several figures of the drawings.

Although the main frame of this clock may be of any suitable construction the same, as shown in Figs. 1, 2, and 8,-preferably comprises upright front and rear main plates 20, 21 which are connected with each other by horizontal bars or posts 22, two front and rear side brackets 28, 24 secured to the front and rear main frame plates and projecting laterally therefrom, a horizontal bracket bar or post 25 connecting the outer upper parts of the side brackets 23, 24, front and rear auxiliary frame bars 26, 27 arranged in rear of the rear main plate, horizontal upper and lower posts 28, 29 connecting the upper and lower ends of the frame bars, and a bolt 30 connecting the front frame bar 26 with the rear frame plate 21.

The numeral 3l represents the tubular hour shaft which carries the hour hand 32 at its front end and which is journaled in suitable bearings on the front main frame plate. Within this tubular shaft is arranged derived from the time motor which includes a coil spring 35 having its outer end connected with the main frame and transmitting motion from its inner end to the hour shaft by a train of gearing operating to turn the hour hand once during every twelve hours and the minute hand once during each hour, this gearing including a main gear wheel 36 operatively connected with the inner end of the Vtime spring 85, a gear pinion 37 meshing with the winding wheel 36 and connected with a gear wheel 38, a gear wheel 39 secured to the minute shaft and meshing with the gear wheel '36, a gear pinion 40 secured to the minute shaft 33 and meshing with a gear wheel 41, a gear pinion 42 connected with the gear wheel 41 and meshing with a gear wheel 43 on the hour shaft 31, as shown in Figs. 1, 3 and 13. The gears 41 and 42 are mounted on an intermediate shaft 44 which is journalcd in bearings on the front and rear plates of the main frame, as shown in Fig. 13. Y

Retarding of the motion of this train of gearing is effected by the usual retarding mechanism consisting of a gear pinion 45 meshing with the intermediate gear wheel 38 and connected with a gear wheel 46, a gear .pinion 47 meshing with the gear wheel 46 and connected with a gear wheel 46, a pinion v49 meshing with the gear wheel 48 and connected with an escapenient wheel 56, and an oscillating pallet 51 engaging with the escapement wheel.

At its rear end the main or minute shaft 33 is provided with a shifting cam 52 and within the main frame this shaft is provided with a star or tappet wheel having four equidistant teeth, one of which 53 is comparatively long and the remaining three 54, being comparatively short, as shown in Figs. 1, 12 and 13.

On the tubular hour sha-ft 31 is arranged an hour striking or main snail 57 having twelve stops or steps arranged progressively further from the axis of this snail and corresponding to twelve hours of a day; and rotatable about the minute and hour shafts is an auxiliary or chime snail 56 which has four equidistant stop faces arranged progressively further from the axis of these shafts. These snails are operated so that the'chime snail 58 turns once during each hour and the striking snail 57 turns once during every twelve hours, this being preferably accomplished by a gear wheel 59 secured to the intermediate shaft 44 and meshing with a pinion 60 secured to the chime snail 5S, as shown in Fig. 13.

The numeral 61 represents the main hori- Zontal driving shaft of the chime andY striking mechanism which is journaled lengthwise in bearings on the front and rear plates of the main frame and is driven by a motor preferably including a spring 62 connected at lts outer end with the main frame and a train of gearing consisting of a main gear wheel 63 operatively connected with the inner end of this spring 62 and meshing with a gear pinion 64, a gea-r wheel 65 connected with the pinion 64 and meshing with a gear pinion 66 on the main driving shaft 61, as Chewn in Figs. 1, 2 and 3. letarding the motion of this train of gears is preferably effected by the usual brake device consisting of a gear wheel 67 connected with the main shaft 61 and meshing with a gear pinion 68, a gear wheel 69 connected with the pinion 68 and meshing with a gear pinion 70, a gear wheel 71 connected with the pinion and meshino' with a gear pinion 72, and a rotary fly .vheei 7 3 connected with the pinion 72.

The bracket plates 23, 24 carry the bearings for the shaft 55 upon which the gear wheel 65 and pinion 64 are mounted, and is journaled in bearings in the outer parts of the bracket plates 23, 24, and the main shaft 61 has its central part journaled in a bearing formed in the rear main frame plate 21 and the rear bracket plate 24 while the front end of this shaft is only journaled in a bearing in the front bracket plate 23, as shown in Fig. 1S. As these brackets are connected at their upper outer ends by a horizontal post 25, the latter and thesebrackets form a separate side frame unit on which. the shafts and gear wheels and pinions just described can be readily assembled and then this side frame can be connected with the main frame and the gear wheel 65 placed in mesh with the pinion 66 on the main shaft 61, thereby facilitating assembling of the clock and reducing its cost of manufacture. The horizontal post, pillar or rod 25 prevents the plates 28, 24 of the side frame from being pressed together or spread apart, thereby avoiding cramping as well as loosening of the shaft 55 in its bea-rings on these plates.

The gear pinion 68 and gear wheel 69 are beth mounted on the same liftingshaft 74 journaled on the main frame and forming part of the mechanism for operating the chimes and striking mechanism.

The main spring 62 at times is prevented from turning` by a locking disk 75 secured to the shaft 74 and a locking arm 76 having a locking linger 77 adapted to engage either one or the other of two equidistant notches 78 in the pe iphery of this disk. Liftingof this locking arm 76 to permit the locking disk 75 to turn is effected by a releasing shaft 7S), which carries the arm 76, a releasing arm 8O connected with the releasing shaft 79 and provpided with a forwardly projecting releasing linger 8l, a controlling shaft 82 provided with a tappet arm S3 adapted to be engaged by the teeth 58, 54 of the tappet or star wheel, a trip arm 84 arranged on the controlling shaft 82 and having a forwardly projecting trip finger 85, and a vertically swinging detent arm 86 pivoted on the frame and arranged betw-een the releasing and trip fingers 81, 85 and forming part of the counting device ofthe chime and hour striking mechanism as will presently appear.

At the end of every quarter hour one of the teeth of the star wheel engages with the tappet arm 83 and turns the same so as to lift the arms 84, 86, 80, thereby disengaging the locking arm 76 from the locking disk 75 preparatory to permitting the spring 62 to turn the sha-ft 61 and the parts geared thereto. Upon releasing the locking arm 70 from the locking wheel 75 a warning stop arm 87 on the controlling shaft 82 engages with a. warning pin 88 on the gear wheel 71, whereby the gearing is only permitted to advance far enough to carry the respective notch 7 8 in the locking disk out of register from the locking lever 76, but when the respective tooth 53 or 54 of the star wheel clears the tappet arm 83 and the latter swings back so as to disengage the warning arm 87 from the warning pin 88 and the train of gearing associated therewith are permitted to turn forwardly the required extent. TWhen the main shaft 61 has completed its rotary movement the locking arm 76, as will later' appear, is permitted to drop and engage with the next following notch 78 in the locking disk 75 and therebyarrest the operation of the chime and striking mechanism.

The means for controlling the chime mechanism at the end of each quarter of each hour and the striking mechanism in accordance with the position of the chime and striking snails is construct-ed as follows:

The numerals 89 and 90 represent main and auxiliary counting racks having the form of toothed segments which are are anged side by side below the detent arm 86 and pivoted coaxially on the adjacent front plate of the main frame by a pivot 91. The main rack is comparatively long and has at least twelve teeth 92 and preferably more, of which the first twelve serve as counting teeth and the remainder serve merely as lifting teeth. The auxiliary rack has at least four teeth 93 and preferably more, of which the iirst four serve 'as counting teeth and the remainder serve as lifting teeth. In the present case the radial distance of the two counting racks is the saine and the teeth of the same are of equal length, but this is not essential inasmuch as this distance and length can be varied and still permit of obtaining the advantageous results of this invention. The main counting rack 89 is provided with a snail 4arm 95rwhich is adapted to engage the steps or stops of the hour snail 57 and the auxiliary rack is provided with a snail arm 95 which is adapted to engage with the steps or stops of the quarter hour snail 58. These racks when free are turned in the direction for engaging their snail arms with the registering steps of the main and 'auxiliary snails, respectively, by gravity aided by means of springs 96, 97 connecting these arms with the adjacent part of the frame. The free end of the detent arm 8G is preferably arranged ina plane passing between the main and auxiliary racks and is provided on its opposite sides with detent pawls or jaws 98, 99 the former being set forward of the latter or nearer the axes f the gear racks so that when the main pawl 98 engages with an intermediate tooth of the main rack then the auxiliary pawl 99 will be held out of the path of the teeth of the auxiliary rack but after all the teeth of the main rack have passed the main pawl then the detent arm 86 can drop or move farther toward the racks and engage the auxiliary pawl 99 with the teeth of the auxiliary rack.

After the racks have been released by the detent arm and have moved forwardly by gravity and spring means, the same are again moved backwardly the same extent corresponding to the position of the respective snails. This backward movement is produced by a rotary lifting wheel 100 mounted on the front end of the lifting shaft 7 1i and provided with two diametrically opposite teeth or pins 101 which are adapted to engage successively with the teeth of the counting racks and return them step by step into their rearmost position.

By arranging the detent arm 86 above the counting racks and engaging the underside of the same by the trip 'arm 84 while the upper side of the detent arm engages the under side of the releasing arm 80, the counting mechanism is materially simpliiied and less power is required to operate the chiming and striking mechanism.

Arranged in the rear of the lower part of the main frame is a chime ,player drum consisting of four chiming wheels er player disks i02, 108, 10ft, 105 and a striking wheel or disk 106 arranged side by side, the chiming wheels being to the main frame and the striking wheel being in rear of the chiiring wheels. T he chiming wheels are slidable lengthwise on the main shaft 61 and at times turn with said shaft and at other times are held against t rning therewith. Each chiming disk or wheel is preferably made of flat metal and provided on its peripheral edge with an annular row of player pins, tappets, or teeth 107. rlhe several chiming disks are mounted on a hub which consists of a central bushing or tube 108 upon the periphery of which three collars are mounted, a central collar 109, a front collar 110, and a rear collar 111, these collars and bushing being held together by a friction or driving lit and also by peening or upsetting slightly the front and rear ends of the bushing against the foremost and rearmost faces of said collars. The

fin

central collar is provided at its opposite ends with annular' shoulders 118 which are formed by reducing these ends and upon which the intermediate two chiming wheels 103, 104 are seated with a driving lit, and the front and rear collars 110, 111 are provided on their front and rear ends, respectively, with annular shoulders 112 upon which the front and rear chii'ning wheels 102, 105 are securely ield by a driving tit and also by peening or upsetting the end collars 110, 111 against the end chiming disks or player wheels.

The striking disk or wheel 106 is provided with an annular row of ten equidistant striking pins, teeth or tappets 114 and is mounted by a driving tit on an annular shoulder 115 on the rear end of a tubular hub 110 slidable lengthwise on the adjacent rear part et the driving sha'it 61. rllhis construction of the disks or wheels and hub of the chimes drum and the disk and hub of the striking wheel is very simple, strong and durable and can be easily and economically manufactured.

The striking disk is always compelled to turn with the shaft 61 and at times the chimes 1isks are compelled to turn with the striking disk while at other times the chimes disks are held against turning therewith.

Turning of the striking disk 108 with the driving shaft is eiizected by a driving arm or index arm 117 secured to the rear end off this shaft and provided at its outer end with a forwardly projecting chime wheel driving pin 218 ol' tubular form which constantly engages slidingly with a driving opening 11.9 in the striking disk 106 adj acent to the periphery thereof, as best shown in Figs. 12 and 1-1. Slidable or iloating lengthwise in the chime driving pin 218 is a player wheel driving` pin 118 adapted to engage Vith one or another oi a plura ity o1'l coupling or driving openings 120 in the rearinost chiming disk or player wheel 105. rllhe chime wheel driving pin 118 is yieldingly held in its toremost position relative to the striking wheel driving pin 218 by a spring 210 arranged in rear of the driving arm 117 and secured at its inner end to the hub ot the same while its outer end presses forwardly against the rear end oit the ehiming wheel driving pin 118. The orward movement oit the latter is limited by a stop 21'? having preferably the Jforni ci a disk secured. to the rear end of the pin 118 and adapted to engage the rear end et the tubular driving pin 218.

ln the toi-mer construction the pin 118 was rigidly attached to the index or driving arm 117 and thereby liable to cause stubbing or ainming` et' the mechanism if the hole 120 in the rearmost player wheel 105 did not line up exactly with the driving pin 118 when the player wheels were moved rearwardly for ei"- iecting ehiming action. l/Vith this new construction the pin 118, being yieldingly mounted, will recede it a solid part ot the rearmost player wheel 105 durino' the'rearward movement of the player wheels engages the pin 118 inasmuch as the spring 219 will give way, but when the pin 118 during its rotation with the shaft 61 comes into alf nement with a hole 120 then the pin 118 will be shot forwardly into engagement therewith by the spring 219 and cause the player drinn to be coupled with the shaft for producing a chiming action.

This organi tion therefore permits the wheels to be turned at random without liabilitj7 of amming the pin 118 because eventually a hole 120 will line up with this pin and permit the latter to shoot into the same with p certainty and thus insure proper functioning of the hour striking and quarter hour chimiug mechanism.

By driving the chimes drinn an d the striking disk or wheel adjacent to their peripherios through tl'ie i -ediui'n ci the driving pins 118 and 218 a greater amount of space is available for locating the coupling openings 120 in the ehiming nis I 105, the j )arts are more accessible and more easily assembled, estreme j accuracy in workma ship is not required, power for driving the driuns and striking wheel is applied more ellectively so thatl a lighter spring motor can be used, and the hammers oi the chimes and striking mechanism are not liable to become hung7 or stuck halt way during the chiming or strikopcration due to the lack ol power applied to the chiming and striking wheel, as would be the case ir" wheels were turned by power applied adjacent to the hubs thereof. inasmuch as the linear distance of a circumferential line becomes shorte the radius of the same decreases any inaccuracy in the location of; the coupling` openings 120 are multiplied as the distance of the same from these openings to the axis oit' 'he disk 105 is reduced and it is therefore apparent that greater latitude is permitted in the 'formation of these openings without liability oi" unfavorably a'llecting the working` ot the chiining` mechanism. The several disks are yieidingly held in their foremost position when tree by a spring 121 surrounding the driving shaft (S1 and interposed bet veen the lront side of the driving arm and the hub of the striking disk. In the foremost position of the chiming drum the same is uncoupled trom the main shaft G1, :is shown in Fig. 14, and at this time the drum is locked against turning by a locking pin 122 projecting rearwardly from the rear plate of the main frame and engagino with a locking opening or slot 128 in the Ioremost chiming disk 102. In order to permit o'f readily adjusting the position oi"- the locking pin. 122 to the locking open' this pin is mounted on an adjusting arm 1.2/1 which is capable ot swingtransversely acres the front end of the drum and has its outer end pivoted by rivet 125 to the adjacent part of the rear plate oi the drum and striking the main frame. By turning this arm on its pivot the locking pin 122 can be readily and easily adjusted to the path of the locking opening 123 without requiring extreme accuracy in manufacture in order to insure engaging this opening with said pin the instant this opening and pin are in register at which time the spring 121 pushes the several disk forwardly and causes the chiming drum to be uncoupled from the shaft 61 but maintains the coupling between the striking disk and the driving shaft 61. The rivet 125 which connects the arm 124 with the main frame is preferably made suiiiciently tight so that these parts will remain frictionally in their adjusted position, thereby materially si1nplifying the construction and reducing the cost of manufacture.

The rearward movement of the chiming drum and the striking 4disk is effected by a horizontal rock shaft 126 journaled transversely on the rear plate of the main frame and provided at its inner end with an inner depending cam arm 127 which engages with the cam 52 and at its outer end with a forked arm 128 which engages with the front end of the drum hub on opposite sides of the driving shaft 61. The cam 52 is so constructed that during the first quarter following each hour the same will move the chiming and striking disks rearwardly so that they are coupled by the pin 118 and held in this position long enough for the locking opening 123 to move out of register with the locking pin 122 after which the inner arm 127 drops oif from this cam 52 and the imperforated rear face portion of the foremost chiming disk 102 rides on the end of the locking pin 122 until the opening 123 again presents itself at the end of a rotation and the chiming drum is again moved forwardly into a locked position by the spring 121.

After the cam arm 127 drops off from the cam 52 the same hangs by gravity in a pendant position and its movement toward th-e low part of this cam is limited so that it cannot engage the same by a stop 129 arranged on the rear side of the rear main frame plate which is adapted to be engaged by said cam arm 127 as shown in Fig. 14. By this means frictional engagement of the cam arm 127 with the low; part of the face of the cam 52 is prevented thereby avoiding wear on these parts and also eliminating unnecessary friction which would cause a drag on the mechanism and waste some of the power of the chime and striking spring and otherwise require making the latter more powerful to properly operate the chime and striking mechanism. Y

Below the chimes drum and the striking wheel is arranged a set of bell rods, in the present case live in number comprising four chiming rods 130 and a striking rod 131. These rods are arranged preferablyY horizontally and parallel and mounted at one end on a stationary stand 132 which is supported on the clock case containing the clock mechanism. rilhese bell rods are sounded by a hammer mechanism which is actuated by the chimes drum and the striking wheel in accordance with the present improvement which is construct-ed as follows:

rlhe numeral 133 represents a lower pivot rod mounted horizontally and lengthwise on the lower part of the upright bars 26, 27 of the rear or hammer frame; Upon this pivot rod is arranged a longitudinal row of ha1nmer hubs 134, each of which turns on this rod and is provid-ed with an annular groove 136.

Associated with the disks of the chimes drum and striking wheel and the bell rods are five hammer levers each of which is constructed of a single piece of wire and bent to form a central semi-circular loop 137 which is seated in one half of the groove of one of the hammer hubs and is secured therein by peening or riveting the adjacent parts of the edges of this groove over the loop, as shown at 138 in Figs. 14 and 15, an L shaped lower arm 139 extending downwardly from the lower end of the loop and provided with a hammer head 140 adapted to strike one of the bell rods, and an upper arm 141 projecting upwardly from the upper end of said loop and terminating in a brake finger 142 which is adapted to yieldingly engage a hub or collar 143 on an upper horizontal longitudinal pivot rod 144 mounted on the upper parts of the hammer frame bars.

On the upper pivot rod are fulcrumed a plurality of intermediate hammer lifting levers each of which is secured to one of said hubs 143 and has a lower arm 146 provided with a laterally projecting pin 147 adapted to engage the upper arm of one of the hammer levers and an upper arm 148 having a laterally projecting pin 149 adapted to be engaged by the teeth of one of the disks of the striking wheel or chimes drum. Whenever a tootn of one of these disks, during rotation of the drum or the striking wheel, engages the upper pin 149 of a hammer lifting lever the upper arm of the latter is deflected in one direction and the lower arm in the opposite direction so that the lower pin 147 of the same, by engaging` the upper arm 141 of the respective hammer lever will cause the hammer to be lifted and when the tooth of the respective disk clears said upper pin of this lifting lever the respective hammer drops into engagement with the companion bell rod and sounds the saine. As the hammer hits the bell rod th-e brake linger 142 on the upper arm of the respective hammer lever strikes the adjacent collar or hub 143 and is yieldinglyarrested so that the hammer strikes the bell rod with a springing blow, and as the lifting lever drops back into its normal position the same engages a rubber bumper 150 having the form of a sleeve mounted on a horizontal rod 151 which is supported lengthwise on the bars 26, 27 of the sounding frame, as shown in Figs. 3, 11 and 14.

' In this hammer mechanism each hammer lever is made from a single piece of wire and no counter weights are employed, thereby simplifying the construction, and enabling a better blow against the bell rods to be obtained. Due'to the use of side pins 147 149 on the upper and lower arms of the intermediate levers an easier sliding action of the same on the hammer levers is secured.

The operation of this clock is fully described in the pending application above referred to and the following brief review of the same will therefore answer present reor count-ing racks 89, 90 at which time the chiming and striking mechanism is at rest. The descent of the detent arm at this time is limited by engagement of the main pawl 98 with an upwardly facing shoulder 152 on the front end of the main counting rack.

Upon reaching the first quarter of an hour the first short tooth or tappet 54 of the star wheel will engage the tappet arm 83 and lift the arms 88, 84, 80, and 76 so as to release the locking arm 76 from the locking disk 75 and also lifting the detent arm 86 far enough to disengage the auxiliary counting pawl 99 from the front end of the auxiliary counting yrack 90 but not far enough to disengage the its spring 97 until its gage finger 95 engages the highest face or step of the auxiliary or chiming snail 58, and also permitting the main shaft 61 and the lifting wheel 100 to turn. The instant this occurs the chime drum will turn far enough to produce four strokes on the respective bell rods and then be arrested by the locking arm 7 6 engaging with the next notch 78 of the locking disk 7 5. While thus released the lifting wheel 100 makes a half turn and one of its pins 101 engages one of the adjacent teeth of the auxiliary counting rack 90 and moves the same backwardly one tooth, space or step so that the auxiliary detent pawl 99 can again drop into engagement with the front end of this rack. Dropping of the detent arm so that its auxiliaryV pawl 99 engages with the front end of the auxiliary counting rack also permits the ylocking arm 76 to, drop into the next notch 78 in the disk and stop its rotation, thereby arresting the operation of the chiming mechstar wheel release the locking arm 7 6 from i the locking disk 7 5 and permit the auxiliary counting rack to move forwardly two and three steps in accordance with the second and third higher steps of the auxiliary snail but Still holding the main rack in its rearmost position, whereupon the chimes are sounded twice and thrice, respectively, and the auriliary counting rack is moved step by step back into its rearward position and then the chiming mechanism is stopped. After each backward step of the auxiliary rack 90 due to the rotation of the lifting wheel 100 the pawl 99 engages with the adjacent tooth 93 of the auxiliary counting rack, as shown in Fig. 7 and prevents the same from moving forward while the lifting wheel is out of engagement with this rack.

At the end of the first hour the fourth or long tooth 58 of the star wheel turns the arms 76, 86, 84, and 89 a greater extent so as to first operate the chiming mechanism for sounding the chime rods four times and then operate the striking mechanism for sounding the striking rod once. Then the detent arm 86 is raised at this time both the main pawl 98 and the auxiliary pawl 99 are moved .out of the path of the main and auxiliary counting racks 89, 90, as shown in Fig. 9, thereby permitting the auxiliary rack to move forwardly four spaces or teeth and the main rack to move forwardly one space or tooth in accordance with the position of the auxiliary and main snails at this time. After the counting racks have been thus moved forwardly the detent arm 86 drops and engages its main pawl 98 with the main rack between the first and second tooth thereof for holding the main rack, while the auxiliary pawl 99 is-out of engagement from the auxiliary rack, as shown in Figs. 5 and 8. As the lifting wheel 100 now turns it first moves the main rack backwardly one step during which the chimes are sounded for the first quarter hour, and the auxiliary rack is moved idly. Following this the detent arm drops sufficiently to move its main pawl98 into engagement with the front end of the main rack and also engages its auxiliary pawl 99 with the space between the fourth and fifth tooth of the auxiliary rack. The rotation of the lifting wheel now moves the auxiliary rack back four teeth during which the first, second and third tooth cause the chimes to be sounded for the second, third and fourth quarters of the hour, and then the auxiliary rack is moved backwardly its fourth and last tooth or space during which the striking mechanism is operated to sound one oclock.

During the first, second, third and fourth quarters of the hour the chiming disks 102,

103, 10st and 105 and the striking disk 106 are held in their rearmost position by the locking pin 122 engaging with the imperforate portion of the foremost disk 102, during which time the chiming disks operate their respective hammers but the striking disk 10G is moved away from the pin 11'9 of the intermediate lever associated with the hammer of the hour striking mechanism, as shown in Figs. 3 and le so that the latter is not operated. After the chiming disks have turned far 'enough at the end of the hour to c sound the chimes four times, the locking opening 123 of the foremost chiming disk 102 registers with the locking pin 122 and is instantly engaged therewith by the pressure of the spring 121 which pushes all of the chiming and striking disks or wheels i'orwffirdly, thereby holding the chiming disks against turning but bringing the striking disk into line with the upper' pin 149 of the intermediate lever 1li-6 of the striking mechanism and causing the latter to be operated by the rotation of this striking disk 100.

At the completion of each additional hour the main counting rack advances one step further and therefore has to be moved backwardly a correspondingly increased number of steps in order to return the same to its home position by means of the lifting wheel, but the auxiliary rack at the end of each hour always advances four steps. As the main rack increases the number of its forward steps the first four return steps are always taken o the main counting rack to operate the four quarters of the chiming mechanism and the remaining return steps for operating the striking mechanism are partly taken olf from the main counting rack and then always completed by counting the last four steps olf the auxiliary counting rack. For exa-mple, when the time is nine oclock, as shown in Fig. 4, the auxiliary rack moves forwardly four steps and the main rack moves forwardly nine steps at the end of this hour and in operating the chiming and striking mechanism the iirst four counts are taken off the main rack for sounding the four quarters of the hour, then the striking mechanism is operated nine times by taking the remaining tive counts from the main rack and adding thereto the four counts of the auxiliary rack.

This organization of chimes clock is materially simplified in construction as compared with the structure shown in the application above mentioned, the same can be manufactured more economically, and it is not liable to get out of order.

The net result of all of these improvements combined is to prevent, as far as possible, jamming of the striking mechanism and the bending of parts and lockwork by the pushing of the minute hand against resistance in attempting to reset or restart the clock, and with these improvements it is possible to turn the minute hand at random backwards or forwards at any time, even during the process of striking of the clock, without meeting with resistance or jamming, and demonstrations have shown that it is practically impossible to disarrange the striking mechanism through manipulation of the minute hand with these improvements.
