To all whom it may concern:

s y j fi@ Becitknown that-wc, HENRY E. PHELPS,

Bnazrnnn, T1... KIRK, and JOSEPH CoMsToCK, citizens.' ofthelnited States of America, rey-s1ding at Rifle; 1n .the county of Garfield .and Statev of fCfoloi'ados have invented cer-- tain new and iuseful Improvements in Springfll/Iotors, ofwhich -the following is a 1 speciiication, reference being had therein to the accompanying drawing.

This invention relates to a spring motor and has special reference to divisional sub- ]ect-imatter.contained 1n our prior appheaz tion, Serial Number 60,927, iledNovemher 15,711; Vv1915.1'and which is now U. S. Patent V;f11,239,037,,issued Sept. 4, 1917. .One object of this invention is the pro- .'rduction lofia spring mot-or which is so con- .structed as to intermittently rotate a shaft @connected-thereto.,`

`Another .objecty of this invention is the .1'productionofv aspring motor wherein a chccl'c mechanismA is employed for holding -:,-fti ie1o.peratmg n'iechanlsm of the shaft for 2.5lpnedetrniined 'A intervals whereby as thecheckmechanism releases the operating v. .'mechanisnnthe.shaft will be rotated.

`lYith these and other' objects in view this .:ifinvention consists in general of certain novel 3.0.. combinati ons, constructions and arrangements of-p'arts as' will be hereinafter. fully i :described and claimed. In the drawing: Figure 1 is a side elevation of the spring motor. Figi '2.isaatop plan view of the spring motor, the .casing being removed. "fjFigxSlis a. side elevation of a portion of the spring motor. $0 Fig. 1 is a side elevation of the check Wheel. y

Fig. t5 is a detail perspective view of the check lever. l

Referring to the accompanying drawings: by numerals, it will be seen that the frame comprises an inner side section 1 and an outer side section 2. These side sections 1 and 2 are held in spaced relation by means of the straps 3 which have feet 4 extending from their inner ends so as to permit the intended to carry .a disk or anyl other oper.-

,ating device 7 desired upon4 its outerend,

as shown in' Fig. 2.' This shaftcvisprovided with a collar 8 hearing againstthe inner side section 1, as shown in Fig.'2, while adjacent its-opposite end it .carries a pinion 9 shrunk thereon or otherwise secured thereto, and on Shaft 6 there iscarried a ratchet 10. Thespring .11` is carried Iupon the frame 1 and is retained in aset.`

spring 11 will cause rotary `motion to be imparted througlrthe. pinion -141v and the gears 15l and 9 to the shaft swhenxthese.t gears are released.

1 t -:1-.A 75 In order to'checlt the operation offthe spring 11,'however, thereis provided agpinion 16 carried upon theshaft 1,7 mounted upon the sections 1 and 2, and -lthis; shaft-,17v is also ,provided vwith a gear18.1Thef` U- 80 .Shaped pawl 19 is secured Ymeans ,of the rivet 2O to the rotatable shaft`21 also- ,ear-

- ried by' the hennep-This paw] :1W- engages the gear 18 and, therefore, .holds thefgearg; against rotation, thus holding lthe spring from operating until the pawl 19rreleases the gear 18. In order to hold the-pawlf'flt) 4in such engagement with the gear 18 V sol as to prevent the same from Acontinuously rotating, thereis provided a strand22 having 90 an offset end- 23'.l and `this strand 22 iscarried by the rotatable shaft 2 1. as shown in Fig. 2. The manner in which this strand 22 is held ina releasable set position .will

be hereinafter set forth.

It will also be noted that the outer section 2 of the frame is provided with a strap 24 carried thereon and spaced therefrom, as shown in Figs, 1 and 2, so as to 'permit the lever 25 to be pivotally mounted thereon.` 100 This lever is provided with a pawl 26 which engages the ratchet 10, and this ratchet 10 is provided with spaced teeth as shown clearly in Fig. 1. -A coil spring 27 is connected to the forward end of this lever 25 and is also connected to the shaft of the spring 11. Asa consequence, the pawl 26 is normally held in engagement with the gear f 16. This lever is also provided withy a lug 28' formed thireon for purposes to be hereinafter set forth. Y

.Adjacent the opposite end of. the frame there is carried a shaft 29 having a spring 30 vkeyed thereto in any suitable manner, this Spring'30 being Wound by the key 31 carrled upon the outer end of the shaft 29. This spring 30 has the large gear 32 fastened thereto; gear 32 meshes with the pinion 33. The gear 34 meshes with the pinion 35. suitable manner to the pinion 35 While the dog 37- is pivotally mounted upon the'shaft 38 carried upon'the upper portions of the frame. lThe counter-balancing strand 39 is connected to the dog 3f?. as 'shown' in Figs. 1 and 2, so that the counterbalancing strand will cause the dog 37 to swing back and forth, thus permitting the gear 36 to rotate with a checked action, thus permitting the y,shaft 41 has a cam 42 keyed upon its outer` 'endfso that as the shaft 4l is rotated the nam gaat" 34 to impart a rotary lmotion to the gearv carried vupon thev shaft 41. This will come int-o engagement With the lugs' 25 ofthe lever 25 for swinging the pawl 26v and` this lever from engagement With the ratchet :10 at intermittent intervals.

keyed the check Wheel 43 which has a notch 44 formed in its periphery, as shownin Fig. 4. As a consequence, as the paWl 42 is rotated it will also be seen that the check seen that the tension of the spring 11 Will cause rotary motion to be imparted to the shaft 6, although after a short portion 0f the revelationof the shaft l 6 .the movement vmoving the pawl 19 into The gear 36 is also connected in any` Adjacent theoppositeend of this shaft 41 there is also Meehan Vratchet l0 for checking .the action of thel shaft independent of the checking action imparted by 'the paWl 19 upon the gear 1.8. It

is obvious that as the check Wheel 43V continues to rotate, theoiset end 23 of the check strand 22 will move out of the notch 44, thus checking engagement with the gear 18.

From the foregoing description it Will be ,seen that at intermittent intervals the lever and checking strand Will be operated so as to release their checking action upon the tension of the spring` 11, thus permitting the shaft 6 to rotate fora predetermined interval after Which the] checking action is -again assumed, thus causing the shaft to be again held 'for a predetermined interval Without moving. WVhat iscl'aimed is Tn a device off-'the class described, the combination With a supporting frame, driving means carried by said frame, of a shaft carried upon said frame, a-gea'l` carried by said shaft and driven by said driving means whereby said 'shaft will be actuated., a check# ing Wheel carried upon saidshaft and hav.
