i' ISii*ecifration fiLetters Patent.` i p of lllinoisglnive invented a new and-useful l ,linprovenient inft'loelis.. ot'which the t'ollowing' is a speeitieation. Y f

M v invention relatesl lo an improvement in t ze ela-ss .ol long-period clocks, meaning` thoee which are adapted' to run with afsinele manual windingl `for a year or more, in lthe easeotpendulmn-cloelts. f

A known type of .clockin the class .rc- 'terred to.l and upon which iny invention is especially designedv to atlord an"improve nient, en'iploysa Tlialul-wt-nmd primary spril'lg'anotor, o1 the tlat-coil. variety, ffor periodically winding'7 h v ,its'reeoih a similar hut relatively light spring` which drivesI the flock-train,` fthe power "of which i lighter spring is expended not only for-drivingl the train but also t'or overcomingl theresistanee ot a normally-loelieil release for the spring'- inotor lo enahle the latter to act. By this arrangement, as the unwinding' ot' the stored-po\\'er or primary motor progresses. its action heeomes retarded with the result ol varyingl and renderingI inaccurate. the time-lteepineot the eloelt.

'l'he ol ieeti ol2 my invention is to "provide a construction ot' elocl; in the aforesaid elass which shall dispense with all v'resistance' to he overcome, such as the release ahove inentioned, interposed between lihe primary motor and the ehuflg-train other than vthe resistance presented hy the. lighter traindrivingspring` to winding,` \\"he'reh'vy sui-h wiiulinu as well as the nmvinding'fotl the liohler .springshall be continuousand imit'oriu. with the advantage ot rendering' the runningot the clock regular.

.ln the accoinpanying' drawings, Figure l is a ln'ok'en sectional plan View of a ,so-called annual clock einhodyingny my improvement; 2 is* ait-enlarged broken sectional view of the train-driving spring device, showing the preferred inanner of `gearing it at; its opposite ends, respectively, to the .spring-motor and train, 'and Fig. 3 is a seetion on line File'. Q. p

.lhe 'clock-case fl, which may involv, any usual or desired general. forni and construetion, contains in one end a frame 5 for holding` thc stored-power motor, usually pro vided in clocks of the present class in the Yt'orm o't'twvo similar flat spring-coils G and ywith Patented 275, 1910.A

T carrying '."orrespoiuling gears S and 9 meshing-with afpinion l() interposed between them and adapted to he wound at keya'rl'iorsll. ill projecting through the case; and.- `detent-ineehanism l'is provided on eaehspring'. ()nl.v lawportion ot' the cloektrain 13 is illustrated, since it maybe ot' ordinary construction,4 presenting no features of novelty, and turns lin the usual way shat'ts 'A14' and 1.3 carrying, respectively, the hour and minute glass-covered vdial 1S.

Between the springs tand' there extends from the frame 5 a bearing l!) in which is rigidlycontined one end ot' a cylindrical core. 20Whieh passes centrally through and thusjournals the pinion l() and its sleeveextension eontined against longitudinal displacement hetween collarsl '21 and Q2 on v the core. Adjacent to the collar 2'2 the core has tormed upon it a eylindrieal enlarge ment'l to perform the poner-reducing function hereinafter explained; and the opposite, end of the core is rigidly supported in a hearing,` @il on the frame of the clocktrain, adjacent to which it passes centrally through and thus journals a gear-wheel littL havin;r ay sleeve-extension 132 and meshing' the tirs-t- {Ljear of the train. rlhe, core Is shown curved toward its end which engages' the wheel 13. owingte the relative disposition ot the parts to attain ycompactnessjwthough otherwise the core might,y he straight.' A eloselvwound, relatirely-light spiral-spring' Q5 surrounds the core, with one end secured to the sleeve 10 and its opposite end to the sleeve 132.- 'l

lVith the motor-springs G and 7 wound np, they eoiiperattnhy their recoil-force in l( jradually unwinding'` which may-continue for a year or more. to continuously and regularly turn they pinion in one direction. lly so turning" the pinion iti winds and tensions the spring-Q5 throughout its length about the core as far as resultant hin jgiiig it ahout. the enlargement 23 will permit.; and as the winding proceeds at the end of the spring adjacent to the pinion the tension toward the opposite end overcomes the resistance ot" and drives the clock-train hy corresl'ionding unwinding of the spring toward that end. Thus the continuous and uniform turning;` of the pinion constantly winds the relatively light, springy 25 aty one end while it. is unwindine' correspondingly at the opposite end to drive the train; and the enlargen'ient Q3 hands lt and 1T about a.

. movement and lever-movement clocks.

Thile the primary motor is herein described as a pair of coiled springs acting against a pinion 10, and might be one such spring. any suitable variety of primary motor is contemplated as being within my invention.

What I claim as new and desire to secure by Letters Patent is- 1. In'a clock of the character described, the combination With a primary motor and a clock-train, of a core, a spiral spring about the -core having one end geared to said motor, for contracting the spring to tension it about the core, and its opposite end geared to the train, and regulating means cooperating with the spring between its ends to form the train-actuating spring-section and limit the extent of tensioning said section, for the purpose set forth. v

2. In a clock of the character described, the combination with a primary motor and a clock-train, of a score provided With an [SEAL] Correction in Letters Patent No. 973,854.

enlargement between its ends and a s )iral 'spring about the core and said enlargement having one end geared to said motor and its opposite end geared to the train, for the purpose set forth.

-3. vIn a clock of the character described.,

the combination with a primary motor and a clock-train, of a rigid cylindrical core, a pinion journaled on said core and engaged by said motor to be continuously driven thereby, a spiral spring about said core havingone end connected With the pinion for contracting the spring to tension it about the core by the power of said motor, and its opposite end geared to the train, and regulating means cooperating with the spring between the ends to form the train-actuating spring-section and limit the extent of tensioning said section, for the purpose set forth:-

4. In a clock of the character described, the combination with a primary motor and a clock-train, of a stationary cylindrical core provided with an enlargementbetween its ends, a pinion journaled on said core and engaged Iby said motor to be continuously driven thereby, and a spiral spring about said core and enlargement having one end connected with the pinion and its opposite end geared to the train, for the purpose set forth.
