SPRING DRIVE MECHANISM.

and the invention has for its objects to pro vide a driving mechanism of the type set forth, 1n a manner as hereinafter referred to, which is comparatively simple in its construction and arrangement, strong, durable and efficlent 1n its use, and inexpensive to y manufacture.

- To the accomplishmentl of these and such other objects as may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts herein specifically described and illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that the device shown is merely illustrative and that various changes in the form, proportion and minor details of construction may be resorted to, without departing from the principle or sacrificing any of the advantages of the invention, which come within the scope of the claim hereunto appended. v

In the drawing forming a portion of this specification and wherein like numerals designate corresponding parts throughout the several views:

Figure 1 is a top plan view of a spring drive mechanism in accordance with this invention.

Fig. 2 is a sectional view of the device on line II-IL Fig. Y1. Y

Referring in detail to the drawing, the

- spring drive mechanism, in accordance with Specification of Letters Patent.y Patented Oct.' 12, 1920 Application medrnsembef 2e, 1919. seriarNo. 346,353. Y

y A pair of integrally formed gears 6 vand 7 'are mounted forrotation on the bearing 4 within the gear casing 1. VThe top gear-6 is of less diameter than the bottom gear 7.

Rotatably mounted on the shaft`5 and seated on top of the bearing 4 is the spring casing 8, in 'which a coil spring 9 is carried.

One end Vof the spring 9 is connected,vas at 10, to the shaft'5,'while the other endth'ereof 1s connected, as at 11, to the spring casing 8. The spring casing 8 is further provided with a suitable cover plate 12.

A gear ring 13, having teeth formed on its inner periphery, is mounted on top. of the flange 3, of the gear casing 1, and mounted on the gear ring 13 is a casing ring 14, which latter surrounds the spring casing 8, and is provided with the top plate 15.

The gear casing 1, gear ring 13, casing rlng 14, and the top plate 15 are securely connected together by means of the bolts 16, as clearly shown in Fig. 2,v of the drawing.

The upper end of the shaft 5 is suitably journaled, as at 17, in the top plate 15, and carries the operating gear 18 iXedly mounted thereon. by means of the screw 19. A winding gear 20, provided with a hand-hold turning bar 21, is Vsuitably journaled in the .top plate 15 and meshes with the operating gear 18.

To prevent the return movement of the shaft 5 when the spring 9 thereof is wound,

is rotatably mounted on the i shaft 28, which latter is fXed to the bottom Y of the spring casing 8 adjacent the outer edge thereof. The pinion 27 is positioned intermediate of the top gear 6 and the gear.

ring 13 and is in mesh with both.

A vertical shaft 29, suitably journaled in the casing of the mechanism in any desired manner, carries the pinion' 30 at its lower end and the transmission gear 31 at its upper end, both of which are fixed to the shaft 29 to turn therewith. The pinion 30 meshes with the bottom gear 7 to drive the transmission gear 31 which connects to any appl'b ance ,it may be desired to operate. A

` tensioned around the shaft 5 and attachedl catch22willho1d thespring 9 in the ten.

sioned position. The spring 9 now being to the latter and to the spring casing 8, will cause" the s ring casing 8 to rotate on theV shaft 5. pon such rotationl the pinion 27 will be rotated by itswengagement with'the stationarygear ring 13 and rotate the gear v6 with which the pinion 27 also meshes. The gear 7 being'integral with gear 6 will alsoy be rotated and causethe'rotation ofthe pinion 30, shaft 2491and thetransmission gear 31.

`What I claim is: .Y i A dr1v1ng mechamsm compr1s1ng Ya power transmitting spring, .a casing connected 20' therewith and revolved thereby, a gear casing having a stationary gear rackxed thereto, apinion carried by the spring cas ing and operated by said gear rack during the revolution of said spring casing, a gear 25 gear mechanism,'said shaft further consti; 30

tuting a winding element'forsaidspring. Intestimony whereof I aix my signature.
