MECHANICAL MOVEMENT.
Application sled :mnu-ary '23, l1922, seriai No. 53151241 Renewed rune 2e, 19a-5.
`To all whom t may concern Be it lino-wn that I, ELWERT '-CorrMAN, a citizen of the United States, residing at Lorain, in the county of Lorrain and State of Ohio, have -invenatedcertain new and rangements Iof parte, hereinafter fully described yand.particularly pointed out in the appended claims.
In the accompanying drawings: Figure 1 is a side elevation ofthe device,
`lonelset ofcover plates ybeing removed.
Figure 2 is a vertical transverse sectional view ftalren lon tlfreline 2-2 of Figure 1.
`Figure 3 is `a vertical section on the line 3-3of Figure-2'.
Figure 4 is a detail view of the operating lever.
Referring more particularly to the details of thetinvention, 'the numeral 1 designates' a suitable base which includes spaced vertical bearings 2 `and 3f. Projecting inwardly from the bearing 2 is a stud 8, which is employed to constitute a pivotal mounting or horizontal axis for the reception of an operating lever 10. This lever is adapted to be oscillated about the stud 8 in any suit-able manner either by manual ormechanical means. The ends of the bearing 2 are also formed to include studs 11 vertically spaced from the stud 8, and the inner ends of the studs 11 are positioned within arcuate slots 12, formed in the lo-wer part of the lever 10, said slots being on a radius struck from the center of the stud 8 and are situated in relative offset relationship, permitting of the oscillation of the lever within prescribed limits.
` The studs 11 project through the slots 12 and comprise axles or gears 13 and 14, the lower gear 14 having the spur teeth thereof arranged for engagement with a cog 15, mounted upon driven shaft 16, which is journaled in connection with the bearings 2 and 3, and by the provision of the movement, mechanism is provided for rotating the shaft 16 in a single specilied direction, irrespective o1 the direction of "oscillation of the main actua-ting lever 1'0. To eitect this result, the backs of the gears 13 and 14 include studs or pins 17, whichare received within vertically extending slots 18 formed in the lower enlarged part of the lever 10. It will be observed that the pins 17 are 'eccentrically mounted on the gears 13and 14 with respect to their true axial-centers, and therefore upon the oscillation of the leverv 10, rotary movement will be imparted to the gears.
To cause the gears 14 and 15 to rotate in predetermined directions, each oit' the gears 13 and 14 is formed to include inner and outer sections 19 and 20 respectively.- These sections are concentrically' situated, ythe inner section receiving the studs 11, while the outer sections are provided with the gear teeth and will rota-te independently of the inner sections. The inner sections 'are provided contiguous to' the peripheries thereof with inclined slots 21, in which are posi-- tioned roller elements 22, normally 'forced toward the reduced ends of said slots by meansof springs 23. To retain the inner sections 19 within the sections 2O cover plates 24 are provided, as clearly shown in Figure 2.
By the instrumentality lof this construction, it willbe seen. that in operation when the lever 10 is oscill-ated, the inner sections of the gear elements will be caused to revolve in unison with the lever by reason of the positive connections existing therebetween provided by the pins 17 and the lever slots 18. However, when the lever is oscillated in the direction indicated by the arrow B, the rollers 22 in the slots 21 provided in the upper of the gear elements will be forced toward the reduced ends of said slots, thereby frictionally uniting the inner and outer sections of the gear element so as to cause said sections to rotate unitarily. This results in imparting power to the lower Agear 14, causing its outer section tio rotate independently of the inner section, this function being admitted because of the fact that the slots 21 in t-he lower gear element are reversely disposed with respect to the same slotsin the upper gear element. Now, when the lever is oscillated in the opposite direcf by the arrow B. This construction provides a simple, powerful and effective means forV eii'ect-ing the rotation of the shaft or other body in a predetermined direction by means of an oscillatory lever.
What is claimed is: Y
1. A mechanical movement including a pair ot gears, each of said gears including inner and outer sections, axial supports for said inner sections, pins projecting from said inner sections and disposed eccentrically of said supports, an oscillating lever, a pivotal mounting for said lever disposed equidist-antly between said supports, said lever having slots therein for the reception of said pins and means situated between the inner and outer sections of said gears for selectively rotating said gears in accordance with the direction of oscillation of said lever. y
2. In a mechanical movement, an oscillatory lever, a pivotal mountingfor said lever, said lever having slots formed there-in on opposite sides of the pivotal mounting therefor, gear elements including independently rotatable inner and outer sections, said outer sections including gear teeth arranged for intermeshing engagement, axial supports for the inner sections of said gears, said supports extending through slots provided in said lever, rigidly mounted pins projecting eccentrically from the inner sections of said gears and arranged to be received within the iirst named slots provided in said' lever, and clutch devices situated between the inner and outer sections of said gears and operative to alternately impart power to said gears upon the oscillation of said lever.
3. In a mechanical movement, a pivotally mounted operating lever, a pair of wheels, each of said wheels including inner and outer independently rotatable sections, the peripheries of said outer sections being disposed in engagement with one another, studs extending axially through said inner sections and arranged to be received within slots formed in said lever, pins eccentricallyV carried by said inner sections and received within a second pair of slots formed in said lever, and reversely operating clutch devices situated between said inner and outer sections and operating in accordance with the direction of oscillation of said lever to alternately apply power to said wheels.
4. In a mechanical movement, a pair of wheels including inner and outer sections, the outer sections having the peripheries thereof disposed in driving engagement with one another, relatively stantionery supports extending axially through said inner sections and serving to vrotatably support the latter, an operating lever pivoted between said supports, pins provided eccentrically upon said inner sections and received ywithin slot-s formed in said lever, saidV inner sections having the peripheries thereof formed to include reversely arranged tapering slots, and roller elements positioned within said slots and operating upon the oscillation of said lever to be alternately forced into and out or' the restricted ends of said slots, said 'elements serving when .in the restricted ends of said slots to unite the inner and outer sections of the wheel in whichV they are situated cr unitary rotary movement, and when in the enlarged extremities of said slots, to admit of reverselyV rotative movement of the inner and outer sections of the wheel in which the said elements are situated.
In testimony whereof I afiix my signature.
