To al l zchom it may concern: ,Be it known that I, CAnL'AUEn, a citizen .of' the United States, and, a resident of I ragaria; in the county of Kitsap and State 5 ofzlvashington, have invented a new and ImprovedClock'Rewinding Device, of which the following is afnll, clear, and exact de- SCL'IPUOD. 1 v

has for an object the provision of an im-' proved arrangement whereby the'motor for moving the power weight of the clock is arranged onsa d power weight and forms part of same.

Another object in view is to providea inotor or power member 011 theweight of a clock together-with associated mechanism,

, whereby the weight will be caused to climb the chain oi-cableconnected withthe clock 'fo'r operating the same, said climbing act on restoring the weight toits wound posi- A still further object in view is to provide a power ineans'for a traveling weight which actsas .tlie weightof a clock, the arrangement being suchthat when the weight is in its highest position the-power will be turned off and when in its lowest position the power .vill be turned on. so that the weight is raised by the actuation of power means and is allowed to move downwardly by the ac tion of gravity. tlie'downward movement of the weight causing the usual movement of the power chain for rotating the clock.

shifting the switch When-the weight of theclock has reachedits highest point; Fig. 10 1 is a view ofthe opposite side of the'meChanism shown in Fig.9; g i

In constructing a devicerembodyi-ngthe,

invent-ion means have been provided which I will notaffect the construction of the clock and which forms parts of theweight opj eratingtlie 'clock; The-construction isv an addition to the weightnow commonly used in master clocks and other similar clocks and.

is mounted principally on the weight soas to form part of the weight though certain connecting parts are provided so that'eleo tricalcurrent may be supplied to the motor for operating the niovingparts In clocks run by weights, as for: instance, master clocks and the like, a power or driving'chain isnsed forrotating the partsof the clockwork and a weight is mounted so astomov-e the chain. The we ght Just referred ito,-,by

the present invention, ;acts in the usualway of moving a weight underthe actionlof gray lty but as soon as the weight; reaches ,its lowermost position the motorand associated parts are immediately started sohthat the weight of the clock will automatically be raised by the climbingaction of theweight,

the same acting on the chain so that there. will be a continual tension onthe chain not only during the downward movement of the weight but during the rewinding thereof. Referring to the accompanying drawings by numerals, 1 indicates the usilia lframe for a clock, which clock is. provided with a power pulley 2 and a master shaft Pass ing over the power pulleyQ: 1s a power 2 chain 4 which is operated a weight but which is of th'e endless Yttrietygfind passes over a pulley 6 at thebottoni of tliefr-ame l. The frame 7 is providedwith ajbase B and uprights 9 and 1.0,. said. uprights being I connected withwhat may be termed atop 11; on ,which the clock ,framework 1,,is

- inountedhi'l his fra neii ork providesa space or compartment in wh ch the weight may move up and vdow,n., Connected; withj-the framework I are uprights 12 and .13 which are provided I with insirl-ating stripsgltaiid 15 earr y-'ii igmetallic conductors lGfia-nd 17. The conductor ltiis connected through wire 18to abattery 19 whil the oppositc side of battery 19 is connected to conductor 17 by a wire 20. It is of course evident that the battery 19. could be grounded on the frame 7 reached.

intermediate the ends. adapted to engage certain mechanism mounton one side while the opposite side couldlibe connected to conductor 16, though prefer with current. from battery or source of sup-- ply 19; .Arri lnge on the upright 13 are stops 24 and 25 adj cent the lower and upper ends respectively and a stop or abutment 26 These steps are ed on the-weight 5 hereinafter fully described; 'sothat the current for motor 27 on weight 5 will be switched off when the weight has been lnovedto its highest position and, will be switched on to the motor when the weight has reached its lowest position. The stop 26 actuates certain mechanism hereinafter described for setting the operating mechanism in proper position for actuation when either stop 24 or stop 25 is As shown in Figs. 5, 6 and 7 the operating parts are arranged at one side of the weight 5 and in a casing or housing 28; Fig.- 5 shows one side of a part of the weight with part of the operating mechanism, while Fig.

7 shows the opposite side. A switch 29 is provided formed with

segments

30 and 31, said segment 30 being connected to one of the bolts of motor 27 while segment :31 is connected with 'a contact shoe 32 engaging the conductor 17. A pivotally mounted arm 33'is arranged on plate 30 and carries a friction member v34 adaptedto pass over the air .to the conductor 16'.- It will be observed that arm.33 is progap 35; When the parts are in the position ,shown in Fig.5 current is flowing from conductor'lZ to shoe 32- and from thence'to plate 31 over arm 33, plate 30, wire, 36 and the motor 27 and after passing through the motor the current passes through. wire 37 vided with a rearwardly. extending lever 38 so as to engage a projection: 39 of'the pivotally mounted arm 40. Arm 40 is pivotally mounted upon'a slidingplate 41 held in place on the weight 5 by suitable pins 42 and 43'extend1ng through

slots

44 and 45. The 1 plate 41 'is cut away at 46 so as to allow afree pivotal movement. of arm 40, *said pivotal movement being caused by a guid-. ing member 47 having the ends-turned in opposite directions so that when the parts move from the position shown in Fig. 5

downwardly the pin 48 extending from arm 40 will strike the guide 47 and be moved to the right in s'aid. figure until the plate. 41 has reached" its extreme lower: position and has allowed the catch 49 to snap into notch .50. The pin 48 operates in a hollowed-out portion 51 in the weight 5 and guide 47 is also arranged in this hollowed-out portion and connected to the weight 5 in any suitable manner. The guide is bent at the lower end in such direction as. to cause the pin '48 to move to the left as the plate 41 moves up- .wardly,,whi1e the pin 48 will move to the right when plate 41 moves downwardly. By this construction and arrangement the downward movement of plate 41 and arm 40 will not. affect the lever38 as the lug or extension 39 is moved away fronnsaid lever. .However, when the plate 41 moves upwardly the extension 39 will strike the lever 38, which is in the dotted position shown in Fig. 9 and move the lever and associated parts to the full line position shown 1n Fig. 5.

I The plate 41 is urged by spring 52 in an upward direction by reason of the fact that the spring surrounds a guiding pin- 53 and presses against a lug 54-iipstanding from plate'41 and against a stop 55 rigidly secured to the weight The stop- 55 forms part of a supporting and guiding plate 56 which supports and guides the plate 41, as shown more particularly in. Fig. 6. The catch .49 which snaps into notch 50 of plate 41 continually presses against the edge of plate-41 by reason of the action of spring 57.. The catch 49 forms part of a bell crank lever 58 which has an extension or projec:

tion 59 adapted to strike the stop 24 at the lower end of the frame 7 whereby plate 41 is released and is caused to move upwardly quickly by spring 52 and thereby turn the switch'29 toethe position shown in Fig. 5..

When the weight 5.is moving upwardly thepin 60 (Fig. 5) strikes'the stop 26 and as the weight continues. to move. upwardly the 'pin 60 together with the bell shaped lever 61 will be pulled or moved downwardly. The lever 61 is. pivotally mounted upon a bracket 62 which is slidably mounted upon a guide rod 63' held in place by suitable 64 is also connected with sleeve or bracket main stationary'as the weight and associated parts move'upwardly. Rod 64 is pivotally mounted to'a double lever 65 which in turn,

is'pivotally mounted at 66 on weight 5in aperture 67. The double lever 65 is provided with an. arm connected with rod 64 and with-a second arm connected with" spring 68, said spr ng being also connected brackets mounted in the casing 28. A rod '62 so that the lever 61 and-rod 64 will rewith a pin 69 whereby the double leyer' is normallydield in'the position shown in" Fig. i 4 6. However, as the weight 5 moves up-' -wardly the lever will be gradually turned and as it begins to 'turn the section 70 of arm 65 will strike pin 71 rigidly secured'to plate 41 and will gradually move plate 41 downwardly T against the action of spring 52. -r'lhismovement.continuesyuntit catchi 4:9; has snapped-into :notch150. i As soonws' r: thlsmbas been:accomplished the cam edge 72. on the l'evewfil: strikes thez rcammeniber r7 3 8 so asftoacausethepin or lug 60m her-disengage"d from step 26. The weight continues to. move upwardly until it reaches its extreme ,upper position, I whereupon certain parts will be operated, hereinafter fully described. Asthe lever 65isturned not only will'section 70 move pin 71-downwardly but the opposite section, namely, section 74, will engage pin'75 rigidly connected with a sliding plate 76 and will move said sliding plate, upwardly against the action of spring-78 which is mounted and arranged in a similar manner to spring 52 except to cause. the plate 76 to move downwardly instead of upwardly. Theimovement of'plate 76 .istconnotchwhich will -take place simultaneous'ly with-the engagement of catch 49 v withno'tch' 50.;- m

It will be observed thatboth the sliding plates-41 and 76 will movesimultaneously and, consequently, will be locked in their upper and lower positions, respectively, simultaneously with orslightly before the lug or'pinGO is disengaged from stop 26. The size of the

notches

50 and 50. is such as to allow a slight movement sons to insure the engagement of the catches before the pin orlugtSO is released Upon the releasing of pin orlug the lever 'will be re-.

' leased and will return to the position shown in 6; under the action of spring 68. -Wh'en-the leveg 65 is moving under the action of rod (ii-the plate 76 will be moving upwardly. and as it moves-upwardly the arm 79 carrying. the IprojectionSO is swung away iifrom the'arm .181 by theguide82 which is if constructedsimilar to guide 49 shown in 3 Fig. 5. The arm 79 is provided with a pin 83 ,whichdirectly engages the guide 82 and which operates in -a recess similar to recess 5 1', while thearm 79'operates in thecutaway portion 84. The guide 82 is bent at the upper end so that when the slide '76 moves downwardly pin 83 will be moved to the 50 right in Fig. K so that the lug or projection 80 will strike the arm 83 and move the shaft and. as said shaft is'rigidly connected 55 g-ddtted lines in F 1g. 9. However, as the sliding plate-7,6 moves upwardly tthezicflt h 49 r engages notch 50 and locks or iliold's plate 76, in itsra'ised position untilthe-.pin 8($-extending fl'lomi't lever 87? carrying: catch j 49 istri'kes the step 125, and T is moved thereby I as the weight; 5, moves-upwardly This will cause the catch;=,49f to be. disengaged and 1 allow spring. {Z8 to quickly forceslide 76 downwardly to the position shown Fig. 65 7, said downward movement causing the wm'aster shaft 3.

tinueduntil thecatch- 49' has engaged the Y movement: of arnr 81. and associated parts as I i above ,;described. uVVhen this has beenacr complishe'd .the -upward movement ofethe weightaxwill be stopped as thepcurrentfrom ba ttery.;19 willbe switched ofi ,The weight then acts in. the usual capacity of a weight communicated to the clockworks through the.

The chain and associatedvparts maybe made of such len ward movementof the weight; I However, as soon as the weight. 5 .reaches'near the bottom of the-framework 7. t he pin 59 on lever 58 strikes stop 24 which willcause h as-to cause the clock, to-run for any desired time upon one down-,

hecatch 49 to move out of not h 50 d thereby release the slide 51 which-.willbe moved upwardly quickly by spring 52 until the parts assume the position shown 7 in ,Fi g. 5.: .As the slide 41 movesl upwardly pin 48 and guide47 swingarmg lO to the right ,(Fig' 5) and cause the projection 39 to strike the extension 38, whereupon the switch arm 33 is moved totfitsnclosedposi-t tion, as shown in Fig. 5, and current is again turned on to motor; 27. This will cause the motor to operate without affecting the direction of movement of the gchain 4 asthe weight continues to act on the chain, though the weightis caused toclimb-thechain by c mechanlsm 7 These up and downrinov'ements are con:

hereinafter fully" described.

tinned as soon as the Current issupplied f by any suitable source. It will be observed that the current is suppliedonly whilefthe motor is tra veling upwardly and preferably such upward movement iscomparatively fast while the downward movement of the weight is regulated by the particular make of clock and other considerations,

In order that the motor QTmay cause may engagethe chain and cau'seua: more )ositive action; Pulley 2 may also be madein the form of a sprocket wheel if desired The pulley or sprocketwheel SS'is rigidly connected with a shaft 89. mounted in suit: able bear1ngs on a bracketQO. A worm gear 91 is, also rigidly secured. to shaft 89, said worm gear meshing" witlila livornihi ijwliich worm isrigidly connected -with;a gear wheel- I 93;]118Slllllg withva pin on 94.. The p nion tH i.

is connected to a shaft 95,015 the armatureo i'f .motor 27. whereby whenever motor 27is operated the power will be 1 transmitted 88 and thereby cause. the weighti') to climb of the clock, a driving mechanism engaging said chain so as to the weight to move upwardly over theazhain, aimotor for oper-' ating said driving mechanism, a-source of IV hen the weight has beeninoved 09318 fextreme, upward position and the sWitclrl-QQ has been opened theweight will naturally rest on the chain but sheave 88 cannot rotate by reason of the worm 92-. This will cause the weight to be locked to one of the sections of the chain, namely, the section 4, assaid section is looped overthe

sprockets

87 and 88. By arranging the rewinding mechanisnr on the weight itself said rewinding mechanisn i' formspart of the weight and does not interfere with the proper operationof the clock as there is always a continuouspul'l on the section ,4-

of chain 4 even though the weight 5 is inov ingupwardly'. q
