'- Application filed November 3, 1904. Serial No. 231,284.

To aZZ whom it may concern.'

Be it known that I, JAMES T. CoxEN, a citiz en of the United States, residing at Sidburn, in the county of Fairfax and State, of Virginia, have invented new and useful Improvements in Spring-Motors, of which the followembodying an auxiliary spring for actuating motor constituting the present and preferred a fan or other extraneous device, and a connection intermediate the device that is vibrated and the said auxiliary spring for placing and maintaining the latter under tension while the motor is in operation, and thereby rendering it unnecessary for the operator to wind said auxiliary spring,

Other advantageous features of the invention will be fully understood from the following descriptionand claims when taken in connection with the accompanying drawings, formlng part of this speclfication, in which- Figure l -is a side elevation illustrating the embodiment of my invention as connected to a spring-supported'body to be vibrated. Fig. 2, is an enlarged vertical section of the novel motor per se, the pallet-lever of'said motor being shown by full lines in its idle 'position and by dotted lines in its active position. Fig. 3 is a transverse'section taken in theplane indicated by the line 3 3 of Fig. 2, and Fig. 4 is a detail section illustrative of the auxiliary spring and the appurtenances thereof. Fig. 5 is a detail view illustrating the relative arrangement of one of the side' plates of the main frame, the perimeter of one of the springhousings, and one of the lateral arms for-connecting the latter to the former.

Similar letters designate corresponding parts in all of the views of the drawings, referring to which- A is a spring-supported device, preferably the spring-supported body of a baby-carriage.

B is my novel motor as a whole, and C is the support on which the motor is mounted. The said support when the motor is used in connection with the spring-supported body of a baby-carriage may be and preferably is formed by the frame of the carriage.

As best shown in Figs. 2 to 4 of the drawings, the motor comprises a frame having side plates a; circular housings b, arranged at the outer sides of the said plates and connected thereto through the medium of lateral arms o, fixedly connected to the side plates and the perimeters of the housings; a transverse primary shaft OZ, journaled in the side plates and extending into the housings, Fig. 3; spurgears e, fixed on the shaft Z and interposed between the inner edges of the housings b and the outer sides of the frame-plates af a transversel shaft f, journaled in the said frameplates and having pinions g intermeshed with the gears e and also having, by preference, an angular end 7L to receive a crank orother device for turning the shaft; coiled springs c', nested in the housings and connected at one end to the shaft oZandiat their opposite ends tothe housings b; a ratchet-wheel j, fixed` through the medium of a set-screw or other means, on the shaft d; a spur-gear Z, loosely mounted on the shaft d alongside the ratchet- Wheel j and carrying one or. a plurality of nected by one or more gears with the shaft d,

preferably through the medium of a gear 2o and the before-described gear Z, anda toothed 'wheel g, fixed on the shaft a and forming part of an escapernent/which 1 will now describe. In addition to the toothed wheel q the said escapement comprises a lever e, fulc'rumed .at a so as to oscillate vertically; a pallet arranged on the short arm of the lever and hav- Aingends which alternately engage with teeth at o pposite sides of a line extending diametricallyacross'the toothed wheel q; ashaft o', journaled in .the frame; an arm d, fixed on one end of the shaft and having a lateral projectione arranged to be thrown into and out of engagement with the lever z after the mannershownby full and dotted lines, respectively, in Fig. 2, and anlarm f', fixed on the opposite end of the shaft c and having a projection g', the said projection g being adapted when the lever or arm f is sprung'away from an upright it on the frame to be moved across the face of said upright and engaged with the IlO IOO

opposite vertical edges thereof. By reference to Fig. 2 it will be seen that when the projection g is in the position shown by full lines at one edge of the upright 7L' the projection e on the arm d' will bear on the palletlever z and lock the same against oscillation or other movement, while when the said lug or projection g is in the position shown by dotted lines the lug or projection e will'be secured out of engagement with the lever e, so as to leave the latter free to oscillate under the action of the springs t'.- By springing the lever f laterally away from the upright t the lug g may be readily disengaged from either edge of the said upright, and the lever may then be moved from the position shown by full lines in Fig. 2 to that shown by dotted lines, and vice versa.

D is 'a connection, preferably a link, which is interposedbetween and connected to the long arm of the lever 2 and the spring-supported device A. The said connection D is designed when the motor is in operation to rapidly move the device A up and down. This movement of the device A when the said device is the spring-supported body of a baby'- carriage will obviously amuse and tend to lull a child i-n the body to sleep.

r is a transverse shaft journaled in the frame-plates a and bearing a gear-wheel s. t is a ratchet-wheel loosely mounted on said shaft adjacent to one of the frame-plates.

u is a pawl connected to one of the frameplates and engaging the teeth of the wheel t, so as to hold the latter against retrograde movement.

c is a spring coiled about the shaft r and connected at one end to the wheel t and at its opposite end to the shaft r.

w is a bar pivotally connected to the springsupported device A and guided by means on one of the frame-plates a.

is a dog carried by the bar w and arranged to engage the teeth of the wheel t on the downward movement of the bar and to ride idly over said teeth on the upward movement of the bar, and a3 is a dog mounted between the frame-plates ct and adapted in the position shown by full lines in Fig. 2 to hold the gear s against rotation and in the position shown by dotted lines in said figure to permit rotation of said gear.

Incident to the up-and-down movements of the device A the bar w will be rectilinearly reciprocated, and the dog carried thereby will rotate the ratchet-wheel t step by step, with the result that the spring 'u will be placed under tension. The gear s is designed to be connected with a fan or other rotary device, (not shown,) and hence it Will be observed that when the dog a is disengaged from the gear .sj the contracted spring e' may be utilized to rotate said rotary fan or device. In virtue of this latter construction it will be observed that the necessity of the operator winding the spring e at intervals is obviated, which is an important desideratum.

As will be readily appreciated by reference to Fig. 3, the arrangement of the mainsprings a' in the rhousings and the interposition of the gears e between the inner edges of the housings and the outer sides of the frameplates @render the construction compact and strong and durable; also, that the shaft f, pinions g, and gears e enable the operator to exert great leverage in winding the shaft d for the purpose of winding or placing the mainsprings under tension.

I have specifically described the construction and relative arrangement of the parts in the present and preferred embodiment of my invention in order to impart a definite understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangementof parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a spring-motor the combination of a suitable frame, a shaft journaled therein, one or more springs for rotating said shaft, an escapement comprising atoothed wheel mounted in the frame, a lever also mounted in the frame, and a pallet carried by the lever and having ends arranged to alternately engage a tooth of the wheel, a driving connection intermediate the spring-actuated shaft and the toothed wheel of the escapement, a bar fixed with respect to the frame, a shaft journaled in the said bar, an arm carried by said shaft and arranged to be moved into and out of engagement with the lever of the escapement, and an arm carried by the shaft and having a projection adapted to be sprung into and out of engagement with the opposite edges of the bar.
