To all whom; it may concern: V

Be itlniovvnthat I, CHAnLns L. MdDo AL, a citizen of theUnited' States,- residing at Monticello, in the county ot'Law'rence and State of Mississippi, have invented certain new and useful Improvements in Springminimizing the heretofore laborious Work associated With the operation of snch deintention is 'disclosedrbrthe' purpose-o1": im-r vices.-

The invention contemplates a main drive shaft having: positioned thereupon and aflixed thereto the 'propellmg spring,vsaid drive shaft having keyed thereto, a master,

or drive gear, which is, through the medium of a trainof gears, adapted to impart'a rotary motion to a vertically disposed shaft, which is adapted to .rece ivefthe npper end of the 'chu'rn' operating handle; further, to mount upon one of the horizontally arranged 'shafts u'sed'in conjunction Withthe gearing, arotary fan, for thec'onvenien'ce of the operator. V r

It' is also amongthe aim's'and-"olojects of the invention to provide a signal or alarm mechanism, which mechanism i's'so actnahle as to operate a signal when the propelling spring has'unw'oundto a predeterminedoex tent; also, to provide a controlling handle whereby the movement of the pro elling springmay be'minutel rewlated; v a

[Arranged adjacent the "side pieces 2 and, affixed thereto; reverti Cally disposed gearing supporting" standards 5 'and6 while s'e'ic-nre'd to andis pportedny one of the side pieces 2" is a right angularly disposed bracket arm" 7; the purp'o e' of whichshall be hereinafterjdescribed; Posi timed between: the -vjertica1 ,sap orting tandards 5 and: 6 a d 1'p'ut' nal a in suitable bearings, provided forjin the sitlepieeesiajs atran'sversely arranged shaft 8, s'a'id sha'ft having a sqnar'edend portion, as 'at 9. and having arrangedthereupon andkeyedthere to a driving gear: 10, which g ar has 'posi tio'n'ed adjacent thereto and ecured" to the same; the conventional manner, as ommon to this particular art, a

propelling sprin 111; which m y be in the form of the ordinary coiled sp'ri'ng' inaho'v'e said transverse shaft 8 and -prefe'rahly in vertical ali nefment the with, is a trans verse Shaft"12',,Which shaft; has arranged var-iat'ly sed forstchtpa poses, Arranged there'on andkey'ed thereto driven ear 13 and a drivin gear 1'4; the latter being f diameter greater". the former; [The shaft; 12 is provided with an elongated' x tension, as designated 1 at '15; which shan'be e subsequently described. Positioned above the shaft 12 and journaled within the supporting standards 5 and 6 is a similar shaft 16, which shaft has arranged thereon and keyed thereto driven and driving gears 17 and 18, constructed in accordance with the gears 13 and 14, while arranged above the shaft 16 and also journaled within suitable bearings in the supporting standards 5 and 6 is a transversely arranged shaft 19, this shaft being of a greater length than the shafts 12 and 16 and having keyed thereto a driven gear 20, a balance wheel 21, a beveled gear 22, and a rotary fan 23, the fan being positioned at the extereme outer end of said shaft.

In order to provide for auxiliary supporting means whereby the beveled gears 22 may be rigidly supported, I provide an angularly disposed bracket 24, which is secured to the vertical supporting standard 6, by suitable fastening devices. Positioned on a suitable bearing arranged in the bracket arm 7 is a vertically disposedshaft 25, which shaft extends upwardly and has arranged on its upper end and keyed thereto a beveled gear 26, which is constantly meshed with the beveled gear 22, while the lower end of the shaft 25 has arranged thereon a circular member 27, which serves to support flexible members 28, these members serving as means for shooing flies away, while the end of the shaft is preferably made hollow, to receive the operating handle 29 of a churn dasher 30, which dasher is mounted within the usual receptacle 31, used in conjunction with churns. The operating handle or rod 29 is secured within the hollow or socket portion of the shaft 25 by means of a cotter pin 32, which is passed therethrough. Pivotally supported as at 33, upon one of the side members 2, is a controlling arm 34, which normally engages with the gear teeth of the driving gear 10, and is provided with a handle portion 35, which portion is acljustably received by the teeth of a rack 36 which is secured to one of the end pieces 3 as at 37.

In devices of this character, it is highly desirable to provide for signaling means for indicating when the spring motor has become unwound, and to this end I provide a substantially bell crank lever 38, which is pivotally mounted between ears 39' carried by the vertical supporting standard 6, and extends through an opening 40 arranged adjacent thereto in the said standard 6 into 7 close proximity with the driving spring 11,

while the upper end of the lever 38 is provided with a right angularly distended arm 41, having a portion 42 bent at angles thereto as shown to advantage in Fig. 5, which portion 41 is adapted to engage with a star wheel 43, splined to the elongated extension of the shaft 12, as at 44, thereby causing sprlng.

said star wheel to be'moved outwardly. Arranged above the shaft 12 and supported by the vertical standard 6, is a distended supporting arm 45, which arm has pivotally secured thereto a bell striking hammer 46, which is adapted to strike a bell 47, also suitably mounted upon the vertical supporting standard 6.

Means may be provided whereby the shaft 8 may be rotated so as to wind the spring 11, thereby providing for the necessary tension, in form of a crank handle 48.

The operation of the device is as follows: assuming that the spring 11 has been wound and that the controlling lever 34 has been disengaged from the driving gear 10, it will be seen that motion will be imparted to the shaft 19 by means of the train of gearing, thus rotating the fan-23 and the beveled gear 22, which gear due to the fact that it is meshed with the beveled gear 26 upon the vertically disposed shaft 25, will rotate said shaft 25, which motion will be imparted to the dasher 30 also causing the fiy shooing arrangement to be operated. Upon continued rotation of the driving wheel pin the spring 11 will be unwound, consequently causing the same to expand and to engage that portion of the bell crank lever 38 which extends into its path, causing the bell crank lever with its projection 41 to be moved forwardly, thus moving the star wheel 43 and causing the same to engage with the bell striking hammer 46, intermittently 0 erating the same and causing the bell 4 to be rung, whereby the attention of the operator may be attracted and thecrank 48 may be applied to the square end of the shaft 8 whereby the spring 11 may be rewound for a subsequent operation.

In accordance with the provisions of the patent statutes, I have described the preferred embodiment of my invention, together with apparatus which I now consider to represent the preferred form of my invention, but I desire to have it understood that the same is only illustrative and that different arrangement of the parts from those shown and described may be resorted to together with mechanical equivalents for some or all of said parts as may be in keeping with the hereto appended claims.

I claim:

1. In a spring motor, a counter-shaft arranged adjacent the driving shaft of the motor and intergeared therewith, an audible signal arranged'in proximity with said counter-shaft, signal operating means movably mounted upon the counter-shaft, and

a lever arranged upon the'motor frame en- 5 gageable with said operatingmeans and the motor spring for moving the operating means into position for operating the audible signal upon expansion of the motor 2. In a spring motor having a countershaft arranged adjacent the driving shaft thereof and intergeared therewith, an audible signal arranged in proximity to said counter-shaft, a hammer for said signal, a star Wheel slidably mounted uponthe counter-shaft engageable at times With said hammer, and a lever arranged upon the motor frame engageable With said star Wheel and the motor spring for moving the Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

In testimony whereof I aflix my signature in presence of two Witnesses.
