,SPRING-Moron SPECIFICATION forming part of Letters Patent No. $67,215, dated February 5, 191,

Application iiled February 1'7, 1900. Serial No.\`5,616. (No modelo "To all whom timmy concern,.-

Be it known that I, OSCAR A. GILBERT, a citizen of the United States, residing at Floyd, in the county offDane andl State of Wisconsin, have inventeda new and useful Spring- Motor, oi-whif-,h the following is a specifica-` tion.

This invention relates to spring-motors,and hasfor one object to provide an improved device of this character for supplying power for any desired purpose.""" `lt is furthermore designed to provide an improved arrangement of governor and brake devices which are applied to the y-wheel of the motor in a`posi tion for convenientadjustment to control the speed of the motor, and, nally, to provide an adjustable winding device which may be thrown out of operative connection with-the motor, so as to remain inactiveduringthe operation of the latter.

with these-and other objects in viewtht4 present invention Consists in the combination after more fullydescribed, shownfin the accompanying drawings, and particularly point-'- ed out in the appended claims, it being understood that changes in the form, proper-- tion, size, and minor details may be made within the scope'of thel -clai'ms without departing from the spirit oI"sacI'iflcingv any of the advantages of the invention.-

In 'the drawings, Figure l' is a Side 'eleva tion of a spring-motor constructed in accordance with the presen-tinvention.4 Fig. 2 is an enlarged transverse sectional view there of. Fig. 3 is a detail plan view pf the winding device. l v

Corresponding parts in the several figures of the drawings are designated by like charactors of reference.

l In carrying out the present invention I provide a frame comprising uprights or cornerposts 1 and the cross-bars 2, connectingthe 'uprights and completing the frame for supwith the ily-Wheel 4. and thefdrive-- wheel- 5,; which:` latter mayberprovided with a wrs'tnpin connecting rod, or it. may be a sprocket wheel for drivinga sprocket chain or belt, as maybe desired or convenient. The lfly-wheel `4 is mounted to turn loosely upon the shaft in a direction opposite to that of the hands of a Clock,-as indicatedby the arrow in Fig. l of the drawings, and is locked withthe shaft for motion in the opposite direction' by means of a ratchetpawl 4, carried by the outer end of the hub of the fly-wheel, and aixed ratchetwheel 3 upon the outer end of the shaft.

Located between the ily-wheeler mastergear 4 and the adjacent side of the supporting-frame is a coiled power-'spring 7, which has its opposite ends connectedto thefy- Vwheel and the fra-Ine of the 'motoigrespectively. ,.This master-gear 4is provided with a peripheral series of..ge'ar'teeth.8 to mesh with v the teethof a smaller winding-gear 9, which ,isflocated-in rear ofthe master-gear and mounted upon' the frame. "of the'winding-goar is carried by a-,slidable Y and arrangement of parts, as will be herein-f. f'-

The stub-shaft lOl bearing'fplate 11, which is slotted longitudi nally and provided with` fastenngs 12,'whichextend through `the -slotted Vportions of the plate to slidably'secur'e the latter to the frame. Any suitable4 operating crank or handle 13 vmay be removably'tted to the outer end of the stub-shaft, so as to provide means for conveniently winding thepowe'r-spring upon the powershaft. It will be'understood that the bearing-plate 11 isadjustable toward andA away from the mastengear, so that the wind'- ing-gear may be brought into mesh with the master-gear to Wind up the spring and also moved out of operative connection therewith.,

so as to remain inactive, when the motor is` in operation. A pawl 14: which is adjacent to the'master-gear and also ismounted upon the uprightV located below the latter, so as to engage the I toothed periphery thereof. This pawl is normally held in engagement with the mastergear by means of a weighted gravity-'deteut 15, which is pivoted intermediate of ltts ends to the adjacent upright, so that its upper light end is in frictional engagement with the under side' of the pawl and is designed Vto be disengaged therefrom by raising the weighted end-of thedetent, so'that the spring 16 may IOO ma@ the WW1 away fromitb masterfgear dur.-

ing' the operation of the motor.

' sion 17, which projects a suitable distance master-gearoriy-wheel. The governor-shaft .ceives said shank. It will of course be unpost, and is provided at its lower end with a governing device comprising a fixed sleeve or The outer ends of these arms are provided with hollow casings 25 to loosely contain the l'fixed s leeve by means of links 28, which have Vslidable sleeve 23 and i's'screw-threaded to ner of any ordinary governor. derstood-.that the governor acts merely in the The upright or end post which is adjacent to the master-gear is provided with an extenabove the master-gear, so as to carry an up-l right governor-shaft 1S, which is mounted in suitable l'iearing-brackets 1,9,Y carried by the pinion 20, which is in mesh with a laterallydisposed series of marginal gear-teeth 21, provided upon the adjacent side of the mastergear and which project outwardly in planes substantially at right angles to that of the extends above the upper end of the post or upright 17 and is provided with a centrifugal collar 22, and a superposed movable sleeve 23, which is slidable upon the governor-shaft and provided with a pair of diametrically opposite radial arms 24, which have their inner ends pivotally connected to the slidable sleeve.

balls-26. Interposedbetween the opposite` sleeves, embracing the shaft and bearing in opposite directions against saidsleeves, is a coiled spring 27 to normally urge the slidable sleeve upwardly and away from the xed sleeve. The radial arms-are connected to the their opposite ends pivoted to the sleeve and to intermediatel points of the arms, respectively. The upperextremityof the governorshaft extends above the upper limit of the receive a suitable nut 29, which is designed to form an adjustable stop for adjusting the limit of the movement of the sliding sleeve. By reason of `this arrangement the governor-4 shaft is operated through the pinion 20, which is in mesh with the master-gear, -whereby the radial governor-arms are elevated 'by centrifugal force against the tension of the spring 27 to govern the operation of the motor and insure a steady movement thereof'in the man- It will be uncapacity of a fly-wheel, as the arms 24 form fans to retard the motion of the motor-'Wheny it is first started, and when friction is sud`` denly removed therefrom.

In order that the speed of the motor may" be controlled,therc is provided a hook-shaped brake-arm or friction-clutch 30, which has a scre\ vthread ed shank or stem 3l, carried by a bracket 32, fixed to the upright 1,7. The upper end of the screw-threaded shank of the brake-arm is provided with a suitable handle 33, whereby the shank may beturned to feed the lattery longitudinally through the screwthreaded opening in the bracket which rederstood that the ybrake-arm has a swiveled connection 34 with the shank, so that the same may turn independently of the latter when it is'desired to longitudinally adjust the device. As best shown in Fig.` 2 of the drawings, the brake or clutch arm islocated at Vthe outer side of the master-gear, and lthe stopped, as'will be readily understood.v It

willalso be observed that the brake and the governor-shaft arel in engagement with o'pposite sides of the (1y-wheel, so as to brace the latter in opposite directions, and thereby prevent twisting of the wheel by the action of either the brake or the governor.

In the operation of the motor the windinggear is turned by means of the crank or handle 13 in a direction to the right or to the movement-of the hands of a clock, thereby turning the master-gear in the opposite direction to wind up the power-spring. It will .nowbe apparent that the pawl or ratchet device 14 is designed to prevent backward lrotation of the power-shaft and mastergear during the -winding` ofthe spring. After the spring has been wound up the brake-arm 30 is adjusted so as to bind the brake -shoe 35 Aagainst the Hange 36 of the -master-gear, so

as tohold the latter against turning, whereby the winding device may be disengaged from the master-gear andthe pawl 14 maybe t rown out of engagement therewith, when the motor is in readiness to be thrown into operation by releasing the brake-shoe 35 from the master-gear.

It will now be understood that the fly-wheel is loosely mounted upon the power-shaft, so as to turn to the left thereon in winding up the spring without turning the shaft, while it is interlocked with the latter by means ,of the ratchet device to impart motion to said shaft when the fly-wheel is being turned-to theright under the influence of the unwinding-spring.

From the foregoing description it will be seen that the present invention provides an exceedingly simple and inexpensive device, in which the parts are'compactly assembled, so as to take up comparatively small space, arm the parts are in position forconvenient access, so that the motor maybe under complete control of the attendant. Moreover, the winding device may be thrown outof operative connection with the master-gear, so as to rid the motor of the unnecessary friction of such winding device when the motor is in operation.

What is claimed isl. In a motor, a spring-actuatcdpowershaft, a fly-wheel carried thereby, a governor, having a shaft, which is in engagement with and driven byoneside of the fly-wheel, and

By this arrangement the y IOO a brake in frictional engagement with the opposite side of the wheel, the governor-shaft and the brake forming opposite braces for the Wheel, whereby the latter is prevented from being twisted by the action of either the brake or the governor-shaft.
