Be it known thatI, lVIIiLIaM ljlsrnn MER- RYMANyWCltiZIl of thejUnited States, re-

siding in the city 'of Richmond, in the county of Wayne, State offlndiana, have invented anew and us'efulCon struction for Spring-lli'otors, of' which the following is a full, clear, and comprehensive specification,

the same being such as will enable others' to make and vuse the'same withexactitude in order to attain 'the highest degree ofeihciency. a

The object of this invention is toproduce a springemotorwhich is especially intended for driving light weight machinery such a for instance, as phonographsorthe l1ke, t0

provide a construction which will be light in weight, imple in constructlon, and winch can be manufactured and sold a compar provide. a springmotor which Will be practically silent or noiseless in operation, and having an lantoinatic governor incorporated therewith. U I a Other objectsq and particular advantages of the invention will 1 suggest themselves in the course'of the following description, and that which is new will be correlatedinthe pp nd d a ms The preferred cans for carrying outmy invention in practical and a mechanical manner is shown infthe accompanyingdrawings, in which- Figure 1 1s 2t' S1Cle 6lEY2ll'/ l() 11 of the mechanlsm ofthel. motor. a F1gL2 1s aplan viewiitaken partly in horizontal section on the line, 2--2 of Fig. 1; Fig. is an end elevationpas taken fromthe right of Fig.1; AndfFig. ljisa detail perspec tivevi'ew of the regulator hanger.

Similar indices denote like partsthroughout the SBVGlTillQVlBWSQ 1110111811 "thatthe construction, the operation, and the advantages of the invention may be more fully understood and appreciatedl will now take up a detailed descriptionthereof inrwlnch I will set forththe several features thereof as fully and as comprehensively asI may. The body of theinotor comprises a frame including the top plate 1 and the bottom plate 2, which are substantially identical with each other, and they are spaced apart by a-plurality of round posts 3,14: and 5, and by the posts 6 and 7 which are oblong 1n cross section. The posts 6 and 7 are arrangedin line with one edge of the plates Specifieatioh of LetteisIPatiit, j 7 Patented ADI". 23, Application filed October 15,1917. Sean; n6, 196,565.

1 and 2, as shown inFig. 2. All of said posts are connected at each end to said plates by screws orthe'like, asthe screws 8 for lnstance.

Thegearing comprises the driving shaft 9 which ispivoted into the plates 1 and2 and it carriesthe two spring'barrels 10 and a 11, each of which contains the usual driving spring. 'The said springs andthe spring barrelsfare so mounted on the shaft 9 that the springs act conjointlyonthe shaft 9,

whereby they act as a continuousfspring fondriving the shaft 9 for a longer' time than a singlesp'ring. Integralwiththe peripheryofthe barrel 10 is the gear 12;"and r integral with theperiphery of the barrel is "the gear .13. Numeral 14 denotes the i in termediate shaft, which is also pivoted in theplates 1 and2. Carriedby-theshaft l l is the pinion 15which meshes with the gear 13. Numeral 16 denotes theintermedi'ate gear wheel which isjalso secured on] the shaft 14. "Numeral" 17 denotes the driven shaft which is pivoted in; the platesl and; 2 and it extends above the plate 1 and carries on itsupper end the turntable 18v Secured around thelower portion, of theshaftlT- it is the pinion 19 which meshes with the gear 16. Also" secured around the shaft 17 is the major fiangedpulley 20 whose function will be hereinafter explained.

" The gooernor.'llie hanger forthe governor is composed of-a central portion2l \vhose length is slightlyless than the distanoe between theplates 1 and 2; Extending in the same direction with relation to each other from. and at right-angles to the d 7 ends offthe member 21 are the arms 22 and 23 which areidentical with each other and each jhason its freeend portion abcaring 24; and 25,- respectively, which are oppositely near the member 21 there areapertures 26 and 27 formed through the respective arms 22 and 23.

secured;- and by which the hanger may be revolved around on] the bolt 28: a

The governorproper comprises the shaft 29 which has its ends pivoted in the'bea-rings 241 and 25. Rigidly securedaround the lower portion of the shaft 29 is the head 30. Slidably mounted on the shaft 29 isthe brake disk 31 which has a disk 32 on its upa per end. Two pairs of ears 83 and 3-1 ex- A bolt28 is inserted through a the apertures 26 and27 and through similar apertures in the plates 1 and 2;where itis disposed with relation to each other. Also i arms 35 and 36 respectively. \Veights '37 tend down from the brake disk 31. Pivoted between the members of said: ears, and 'BX- tending downward and outward, are the and-as are secured on the lower ends of the respective'arms35- and '36.

The-brake comprises the contact 4,2,,whichis carried by the arm 43,. which in turn-:is carried bythe collar 44, the latter surrounds thepost 5. Said collar is adaptedtotbesecured; at anyheight along said 'postia'sby the thumb screw 45, whereby the r "Contact d2. may be secured atfany distance .rromane disk132as desired. ;A spring 4-6 is attachedtoathechanger-and to the plate 1,

belt e8. ;.connects,the pulleys 20 and 47, and

{it is -;,1: re ented-1from getting out of place by thezflanges of; said pulleys. I 1

Thewindingjmechanism comprises a shaft 'springifil' which-is. coiled around the said shaftaone. endvof said spring being secured, asftothe post/Z, andithe other end being unsecured; wh erebyv' it may grasp said "shaft when the shaft is turned in v one direction.

.It1is,apparentthat by placinga crank on the projecting end of the shaft 4:9 and turni I Ein'g the same to-theright that the springs in thefbanrelslO and 11 will bewound' in the usual nianner.-.-..The tension of said springs [will-revolve the barrel ll thereby rotating ,thepinion'ilfi, the shaft 14:,andthegear- .wheeli16;,-. the latter operating on-the pinion -:l 9 ,w;ill;revolye the shaft 17;which W111 ro- :tate the turn-table; 18 in the usual manner. Now as theturnstable speedsgup it isevident that th'e'beltz 4:8, connecting the pulleys 20 and 47 ,ywill-rotate. the shaft 29. Then asthe shaft-29 speeds up it will cause the weights 37. and 38 to swing, outward and apart, thereby drawingthe brake disk 31 downward until the disk 32 contacts with the brake contact 42 which, manifestly, will slow up the speed, and thereby maintaining the speed constant at a predetermined rate to whichthe contact has been Or to which it may be set as required.

. By means of the belt' l8 which connects the driving gea'r'aiidthe governor I eliminate practically all noise ofoperation. By reason of the means I provide for ma1nta1nmaintain the belt at the desired degree of tension at all times. I

I I desire that it be understood that various changes may'be'inade in the several details'o'f construction from that'herein shown and -descr1bed without departlng from the spirit of the invention and without sacrificing any ofjthe' advantages thereof. I
