SPECIFICATION formingpart of Letters Patent N0. 777,663, dated December 20, 1904:.
Application filed May 4, 1904:. Serial No. 206,422.
To all whom it may concern.-
Be it known that I, ELZA J. CHRISTIE, a citizen of the United States, residing at Marion, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Motion-Transmitters, of which the following is a specification.
This invention relates to mechanism for transmitting motion,especially rotary motion, at any desired change in speed and without shock in starting or stopping.
This invention embodies certain novel means for transmitting motion from one cone to another, changing the relative speeds at will, and reversing the movement of the driven as respects the driving cone.
The full nature of the invention will clearly appear in the description and claims following, reference being had to the accompanying drawing, which shows in one plan View all the essential features of the present invention.
In the drawing, A designates a rectangular frame in which is mounted a pair of alternately-disposed cones B and O on suitable axes D and E, respectively journaled in bearings F. The axes of the cones are parallel and the cones of the same pitch as here represented. In any case the center line of the cone-faces nearest each other should be parallel.
In suitable bracket-arms G is mounted a guide-rod H, and on this is mounted to slide endwise and also to turn a limited distance a hanger I. In this hanger is journaled a pair of conical-faced friction-Wheels J, to which motion is positively imparted from one to the other by gears K. When in working position, one of these conical wheels bears against the face of the cone B and the other against the corresponding face of the cone 0. It is evident that the rotation of the respective cones by contact with said friction-Wheels is in opposite directions.
By shifting the hanger endwise on the shaft the relative speed of the cones may be varied at will. This may be done in a simple way by loosening the setscrew L, raising the hanger, so as to free the friction-wheels from contact with the cones, and then moving endwise as far as desired, again depressing the hanger, and setting it in position.
The invention seeks, in so far as possible, to secure theoretical concurrence of movement between the cones and the engaging frictionwheels. This is not quite possible practically in a speed-shifter; but this invention illustrates a satisfactory approach to it. tention is called to the fact that the friction- Wheels are parts of cones whose taper is in the same direction as that of the cones which they engage. It follows that when set at some point along the cone the projected angles of the cone and friction-Wheel will exactly coincide when the action of thecone and wheel are theoretically correct-that is to say, they roll on each other without slippage in any part of the periphery of either. This condition of course changes to some extent as the friction-wheel is moved along the cone in either direction from this point; but for all practical purposes the twisting slip is so slight as to be disregarded. The practical result of the construction is to secure the maximum of frictional surface with the minimum of this twisting slip.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a motion-transmitter, the combination of a pair of cones alternately disposed, and a pair of conical-faced friction-Wheels, mutually engaged, and revolving in opposite directions, mounted between said cones, each wheel engaging a cone, whereby the cones are made to revolve in opposite directions.
2. In a motion-transmitter, the combination of a pair of oppositely-revolving,oonical-faced friction-wheels provided with intermeshing gearing, and alternately-disposed cones engaging each the outer face of one frictionwheel, substantially as and for the purpose set forth.
3. In a motion-transmitter, the combination ner faces of the cones, whereby the frictionof a pair of alternatelydisp0se :l cones, a pair wheels may be shifted, as described. IQ of alternate]y-disposed, conical-faced friction- In testimony whereof I affix my signature in wheels, mutually engaging, and revolving in presence of two witnesses.

and a hanger in which the wheels are mount- JACOB R. CHRISTIE,
