SPECIFICATION forming part of Letters Patent No. 606, 158, dated June 21, 1898. Application filed December 28,1896f Serial No. 617,302. (No model.)
sufficiently full, clear, and exact to enable those skilled in the art to which it appertains or with which it is most nearly connected to to make and use the same. The object of the invention is to provide a change-gearing or arrangement of gearing capable of being so operated or manipulated that the initial power employed to manipu I late the same may be multiplied at the expense of but slight loss of speed and in which is embodied means for rendering the gearing inoperative, or, in other'words, means whereby the power and speed as applied may be ac utilized without change.
To these ends the invention consists in certain new and improved features of construction and arrangement of parts, all as ishere inafter morefully set forth and described in the following description, the novel features of which are particularly set forth and ascertained in the claims at the close hereof.
Of the drawings, Figure 1 is a central ver tical section of my improved change-gearing. 0 Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 shows view of the balls detached. Fig. 4 is a modification. Fig. 5 is a detail.
Referring to the drawings, A represents the prime power-shaft, which may be driven from 3 5 any suitable power source and by any means from which it may be desired to transmit power to other mechanisms or devices. Upon the shaft A is fixed a pinion B, which meshes with the internal gear 0, formed upon the in- 0 ner side of a sleeve D, which surrounds the pinion B. The sleeve D has formed thereon the exterior gear-teeth E, which mesh with the internal gear F, formed upon the inner side of a ring d, which is secured within a 5 drum 6 by being forced therein or otherwise.
their circumference, and the diameters of the pit-ch circles of the gear E and F are preferably of the relative sizes shown, and they in turn engage practically at one point in their circumference.
The sleeveD. has formed therein the groove 6 for the reception of the balls a, Z), I), and c. A ring f, externally threaded and applied to the interiorly-threaded mouth or opening of the drum 6, is formed with a cut-away orbeveled face f, which, together with thebeveled face dof the ring d, also servesas a bearing for the balls at, Z), I), and c. The construction and arrangement of the ring f permits of ad justment of the latter as the bearing for the balls is worn away. Between the rings d and f and encircling the sleeve D, I provide a separator g, (shown in detail in Fig. 5,) which is notched at a, h, b, and c for the reception of the graded ballsc, b, b, and 0, respectively. The object of providing or employing the separator g is to maintain the balls in their proper relative positions as they travel around the groove or hearing within which they lie, they being moved or caused to travel around the sleeve D, within said groove or bearing through the movement of rotation imparted to them by reason of their contact with said sleeve, which is itself revolved by the en gagement of the gear 13 therewith.
The maintenance of the balls in their proper relative positions causes the sleeve D to be kept in engagement with the pinion B and gear F by reason of its eccentric positionwith relation to both said gears. Thus during the operation of the device not only is the speed and power of the rotation of the sleeve D upon its own axis communicated to the gear F, but additional speed is imparted to the gear F through rotation of the said sleeve D around the axis of the shaft Acaused by the travel of the balls around their groove or bearing.
The drum 6 has formed thereon the boss 6 which has formed therein the cone-shaped socket 6 which constitutes one member of a clutch mechanism. The other (shown at 6 is formed with a cone e fitting in the socket 6 The member 6 is splined to the shaft A and may by any suitable means be moved into engagement with the socket 6 By this means the drum may be locked to the shaft A and my change-gearing thrown out of operation and the initial power utilized as applied by transmission through the medium of a belt, chain, or gearing engaging the drum 6 or otherwise.
In Fig. 3 are shown in detail the relative sizes of the balls a, b, and c. The said balls being arranged around the sleeve D equidistant and within the groove or bearing provided for their reception, with the balls at and c diametrically opposite each other, the sleeve D is held in the desired eccentric position with relation to the pinion B and gear I In Fig. i I have shown a modification in which I employ two series of balls at, b, b, and c, by which construction the liability of binding or unequal wear of the parts may be obviated.
Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, it is declared that what is claimed is- 1. In combination, a driving-pinion, an internally and externally toothed eccentric sleeve meshing with said pinion, a driven internally-toothed ring concentric with the pinion and meshing with the said sleeve, and graded balls for maintaining said sleeve in its eccentric relation to the said pinion and rin 2. In combination a driving-pinion, a 0011- centric driven internally-toothed ring, an intermediate internally and externally toothed eccentric sleeve, graded balls for maintaining the eccentric relation of the said sleeve, and
a drum for supporting'the graded balls.
3. Gearing comprising in its construction a pinion; driving means for said pinion; a sleeve encircling said pinion formed with an internal gear, and having gear-teeth formed upon the exterior thereof arranged to engage with the teeth of an internal gear; graded balls interposed between the sleeve and a ring; means for maintaining the balls in their proper relative positions, and a ring concentric with the pinion and encircling the sleeve formed with internal gear-teeth, substantially as described.
4:. Gearing comprising in its construction a pinion; a driven internally-toothed ring; driving means for said pinion; a sleeve encircling said pinion formed with an internal gear, and having gear-teeth formed upon the exterior thereof arranged to engage with the teeth of an internally-toothed ring; graded balls interposed between the sleeve and a ring; a separator formed with notches for the reception of the balls, each notch of a size to accommodate its respective ball; and a ring concentric with the pinion and encircling the sleeve formed with internal gear-teeth, substantially as described.
5. Gearing comprising, a driving-pinion, a driven internally-toothed ring, an eccentric internally and externally toothed sleeve meshing with said pinion and said ring, a rotary drum, graded balls, between said drum and said sleeve, and a separator formed with notches to receive the balls.
I11 testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 14th day of November, A. D. 1896.
