A TTORIVEY ornion OTTO RIEKE, OF CHICAGO, ILLINOIS.

SPRING-WINDING MECHANISM.

Application filed March 29, 1915.

To all whom it may concern:

Be it known that I, OTTO RIEKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Winding Mechanism, of which the following is a specification.

The winding mechanism which is, the subject-matter of the present application for patent is designed more particularly for Winding the spring motor of talking machines, a reciprocatory lever being employed in the place of the usual crank handle.

The invention has for its object to provide a winding mechanism of the kind stated embodying certain novel and improved features of construction and arrangement of parts to be hereinafter. described and claimed, reference being had to the accompanying drawing in which- Figure l is an elevation of a fragment of a talking machine to which the invention is applied, and Fig. 2 is a plan view of the winding mechanism.

Referring specifically to the drawing, 5 denotes the box of a talking machine in which is housed the spring motor 6 which drives the turntable 7 supporting the record disk. The spring of the motor has a winding shaft 8 provided with a suitable pawland-ratchet mechanism 9 to prevent the shaft from slipping back. The outer end of the shaft carries two clutch members 10 and 11, respectively, the same being disks having their contiguous faces toothed to intermesh, the teeth being arranged to transmit motion in one direction and to slip in the opposite direction. The disk 10 is fast on the shaft, and the disk 11 is loose and slidable thereon. Integral with the disk 11, or separate and made fast thereto, is a bevel pinion 12. A spring13 holds the disks in mesh and yields to allow the same to separate. The spring is coiled around the shaft between the bevel pinion and a bearing lat supporting the outer end of the shaft.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Serial No. 17,739.

In mesh with the bevel pinion 12 is a curved rack bar 15 connected at one end to a hand lever 16 which is fulcrumed at its inner end, as indicated at 17, to a suitable support in the box 5. The lever and the rack bar swing in a horizontal plane. The free end of the lever extends out of the boX through a side slot 18, and is shaped into a handle 19.

It will be evident from the foregoing that when the lever 16 is swung back and forth, the rack bar 15 rotates the pinion 12 alternately in opposite directions, and when turning in one direction the clutch disk 11 of said pinion is locked to the clutch disk 10 and thus imparts a rotary movement to the shaft 8 in the same direction. When the pinion turns 1n the opposite direction, no motion is transmitted to the shaft as the pinion slips back and the diskll does not take hold of the disk 10, the pawl-andratchet mechanism 9 holding the shaft against slipping back.

I claim The combination with .a spring motor; of a rotary shaft for winding the motor spring, cooperating clutch members on the shaft, one of said members being fast on the shaft and the other member being loose and slidable on the shaft, a pinion fast on the lastmentioned clutch member, yielding means for holding the clutch members locked together, a rack bar in mesh with the pinion, and a lever extending in the direction of vthe shaft and connected to the rack bar,

said rack bar extending from one side of the lever, and the latter being mounted to swing toward and from the shaft.

In testimony whereof I affix my signature in presence of two witnesses.

OTTO RIEKE.

Witnesses I S. J. LEHRER, H. G. BATCHELOR.
