ADOLPH WAHLE, OF DAVENPORT, IOWA.

MECHANICAL MOVEMENT.

Application filed January 2, 1908.

T o all whom it may concern:

Be it known that I, ADOLPH l/VAHLE, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a clear, full, and exact description.

My invention relates to mechanical movements for use in washing machines, mangles, churns, and other machinery where it is desired to convert a continuous rotary motion of a drive-shaft into a rotary Areciprocal motion of the driven-shaft.

The object of my invention is to utilize the force or momentum of a rapidly revolving` fly-wheel to assist in moving the parts past the point of reversal or dead-center, and thereby continue the operation of reversal with the expenditure of less energy on the part of the operator than would be required if the fly-wheel were dispensed with or not used. This I accomplish by the means hereinafter fully described and as more particularly pointed out in the claims.

In the drawings Figure 1 is a side elevation showing my invention applied, in this particular instance, to the top or cover por tion of a laundry tub. Fig. 2 is a central vertical section taken through the vertical plane of the operating shafts. Fig. 3 is a top plan view of the same. Fig. 4 is a view similar to Fig. 3 having the gear easing removed to expose the parts below the same. Fig. 5 is a detail view of the inner end of the frame -work and the easing showing the manner of disposing` the operating lever.

The supporting-frame for my improved mechanical movement consists of a baseplate 1, and a casing 2 removably mounted upon the same. At the outer end of the base-plate are located suitable horizontal bearings 3, in which a continuously revoluble shaft 4 is journaled. This shaft is provided on its outer end with a balance-wheel 5, while on its inner end a small bevel-pinion 6 is mounted, that meshes with a bevel-gear 7 secured on a short vertical spindle 8 arising from the base-plate. The upwardly extending boss of bevel-gear 7 is provided with a small straight toothed pinion 9 that is fast thereon and rotates therewith. Mounted in vertical bearings in the base-plate, preferably in the same vertical plane with shaft 4, is a suitable rotary reciprocal shaft 10, that derives its motion from the continuously rev- Specication ,of Letters Patent.

oluble shaft 4, through the medium of suitable transforming mechanism that will hereinafter be described. A large gear 11 that has a downwardly elongated journaling sleeve 12, is loosely mounted on this rotary reciprocal shaft 10 in such manner, that, while it engages with pinion 9, and is rotated continuously thereby, its movementis independent of the reciprocal motion of said shaft. Pivoted to a stud projecting up from the top of bearing 3, at one end, is a hori- Zontally reciprocal rack-lever 13, that extends over all of the before mentioned gearing, and has its free end resting upon the smooth upper face of gear 11. substantially T-shaped and is provided at the intersection of its branches with a crossshaped opening, the transverse slot 14 of which is in the same transverse plane as, and is adapted to accommodate the passage therethrough of the rotary reciprocal shaft 10. The longitudinally disposed slot 15 of 4this opening affords a guide for a suitable roller-pin 16, that projects vertically from the upper face of gear 11. The slotted end of this lever extends under a pinion 17 fast on shaft 10, and. the outer extremity thereof is provided with a segmental-rack 1S that engages said pinion 17 and turns the sameA and shaft 10 in a rotary reciprocal manner as it is moved from side to side on its pivot.l A suitable arm 19 projects laterally from the back of rack 17, and extends through an opening in a vibratory operating or hand lever 20, which latter is, preferably, provided with an enlarged ball-shaped head 2l on its lower end, that is adapted to be seated and journaled in a suitably shaped socket 22 cast integral with and arising from the inner end of the base-plate.

In order to provide a covering for the gears, the base-plate 2 is provided, between the two shafts, with an integral mutilated shell 23, that rises, preferably, to the height This lever is llf) gearing. Said band rests at its smaller end on the upper face of gear 7, While its outer or larger portion is provided with a transverse bracket 28 that is seated on the rim of the socket 22. In addition to this protection the upper member 2 of the supporting-frame is provided on each side of the central dome 26 With upturned lips 29, that guard the face of the rack 18 on the reciprocal arm 13.

In operation, the operating lever 2() is reciprocated and moves the segmental rack 18 back and forth, which latter meshes With pinion 17 and causes a reciprocal rotating .movement of the shaft 10. This back and forth movement of the rack moves the roller pin 16 alternately from one end to the other.

of slot 15, thus imparting a rotating movement to the large gear 11, and the latter, through the medium of pinion 9, bevel-gear 7 and bevel-pinion 6 revolves the balance-Wheel suitable sup orting frame, a rotary reciprocalA shaft journa ed therein, a gear loose on said shaft, a pinion secured to said shaft, a continuously revoluble shaft, a pivoted segmental rack engaging both said pinion and gear, and means for transmitting the motion of said rack through the medium of said gear to the last mentioned shaft.
