To -'aZZ whom it may concern:

Be it known that I, FRANK M. WA'rnns, a citizen of the United States, residing at Springfield, in the county Ohio, have invented a new and useful Mechanical Movement, of which the following is a specification.

ot larger diameter than itsel gear in turn meshes into a My invention relates to an improvement in that class of devices for eonvertinga slow rotary movement into a fast one or a fast rotary movement into a slow one with the aid of but one shaft or stud in connection with the gearing by which this result is accomplished.

It consists of a webbed internally-geared in the center bored to receive the shaft, which rotates freely in it. Upon the shaft is keyed or otherwise fastened a spur-gear having a pitch-diameter something less than the pitch-diameter of the internal gear, and when in proper position resting upon or against the web of the internal gear, thus bringing the sides of both upon or nearly so the same line, and leaving a space between the faces of the two gears snfficient to admit a cogged spur-pinion having the same pitch of teeth as the annular and spur gear, and properly meshing into both at the same time. Thespur-pinion is part of aspur-gear f, to which it is fastened on the side, or may more properly form part of the same casting, and this spursmaller gear or which is bored through its center to allow it to run freely upon the shaft, and may be part of or connected to either a with eccentric, crank with crank-pin, pulley, spur, annular or bevel gearing for transmitting motion to other mechanism. The internally-geared wheel may, and in this case does, form part of a casing in which the gearing is protected from dirt or other foreign substances which might interfere with its proper working, the other part of the casing being bolted or otherwise fastened to it sufficiently close to allow the free movement of the combined gear and pinion, and to prevent at the same time any tendency to dip or rotate in any direction other than that desired, and in which it is further assisted by having upon the side of the shaft-pinion a flange or extension of the casting above the tops of the pinion,

cogs. While this movement may be accomplished by using only one intcrmeshing combined spur and pinion, the result will be the same it two or more are used at the same time, with the advantage of equalizing the pressure of the pinion upon the shaft on all sides. It will now readily be seen that by turning the shaft upon which the spur-gear is fastened, and allowing the annular gear to remain fixed, the combined spur-gear and pinion will revolve upon its own axis and at the same time move in. a circle around the shaft. The advantages derived by allowing the pinion of the combined or double gear to run free between the annular and spur, instead of upon a stud or shaft, are, to lubricate at that point, and the required motion gotten with less cost and fewer pieces in building it.

To better ill is had to th Whi011- Figure 1 is a cross-section with the casing partly removed, in which.

Fig. 4 is a side elevation of the central or shaft pinion, c, with projection b, which can be made part of fly-wheel, pulley, spur, bevel, or annular gear, for transmitting the motion, as may be desired.

The mechanism may ustrate my invention, reference e accompanying drawings, in

be employed to produce anyrapid or slow movement, and maybe operated by manual or other power. Numerous obvious applications of the device may be it requires no oil made-such as to mowing and reaping ma- 1 ing into pinion a, with casing A and B, hav- :0 chines, lawn-mowers, and horsc-powers ing' projections E, as shown. Where an accelerated motion is required, and In testimony of which I hereunto set my in traction-engines, hoisting machinery, &c., hand. where a slow motion is needed.
