OF NEW YORK, N. Y.
QPECIPICATION forming part of Letters Patent No. 352,512, dated November 16, 1886.
Application filed May 4, 1886. Serial No. 201,091. (No model.)
To all whom it'may concern.-
Be it known that I, CARL F. 'W. BoDEoKER, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Differential Motion- Transmitters, of which the following is a specification.
My invention relates to improvements in mechanical devices or machinery for the transmission of force or motion at different velocities; and the object of my invention is that,
or a fixed number of revolutions per minute, a variable speed can be obtained and graduated in such a manner that there will be no fixed changes between the two extremes of motion, and that will be perfectly under the control of the operator. I obtain this result by the interposition between the prime mover and the machine or instrument to be driven of what I call a reversible differential motion-transmitter, (placed on a stand or table in a position to be driven by the prime mover,) which is made in the following manner:
Upon a stationary bed are erected two uprights or standards having bearings, in which is secured a shaft in an inclined position, upon which is mounted a truncated conical-shaped drum which is free to turn on the shaft, and the form of the cone is completed by a section with it, is stationary, for the purpose hereinafter described. This drum, together with the shaft, is preferably arranged so that its upper or driving side shall have a horizontal position.
At the large or lower end of the conical drum are arranged three miter-gears, one of which is attached to the drum, and the other two are mounted and free to turn on a driving-shaft which is supported in bearings at each end formed in the uprights. Between these two miter-wheels upon this shaft is placed a sleeve free to move lengthwise of the shaft, but which is made to revolve by means of a feather and spline in the sleeve and shaft. Upon each end of this sleeve is formed a friction-clutch, which engages alternately, as occasion may require, with the miter-wheels on either side, causing them to rotate, and with them the drum. By
a change of position of the clutch from one wheel to the other the direction of rotation is reversed,'and when the clutch is placed centrally between the wheels and disengaged from both, the wheels, together with the drum, will be at rest.
In the upper ends of the uprights are formed bearings, adjustable by screws, carrying a horizontal shaft which is parallel with the upper surface of the conical drum. Upon this shaft is mounted a small drum, the external surface of which is covered with vulcanized rubber, and is free to be moved lengthwise of the shaft, and turns the shaft by means of a feather fixed in the drum working in aspline cut thelength of the shaft.
Motion is communicated to the small drum and shaft from the conical drum by frictional contact, the necessary pressure being regulated by the adjustable bearings. The speed of the conical drum being regular, the motion transmitted to the small drum will be proportional to the diameters of the drums at any point in the length of the conical drum where they maybe in contact, thus securing a graduated variable speed of the upper drum and shaft.
The position of the small drum with refererenee to the conical drum is regulated by means of a yoke mounted on a small guideshal't supported by brackets formed on the side of the uprights and parallel with the shaft carrying thesmall drum. This yoke, together with the small drum, is moved in the direction of the small end of the conical drum by the tension of a coil-spring connected by a cord passing over a small pulley connected with a larger pulley, which is in turn connected by a cord to the yoke. By this means the small drum can be moved over the length of the conical drum by a small extension or contraction of the coil-spring. Thesmall drum, when not in use or not required to revolve, is retained by the spring at the small end (if the cone resting on the small stationary section before described, and at rest.
Attached to the above-described yoke is a cord to act in the opposite directionto that of the spring, passing horizontally to a directionpnlley, thence downward and attached to a treadle, (arranged in the floor,) hereinafter described. By the depression of this treadle the tension of the spring is overcome, and the small drum is moved to any point on the conical drum which will give the required speed.
Motion is taken from the small drum by means of a round belt passing over a grooved pulley formed in connection with the drum, and is also taken from the end of the shaft driven by the small drum. The reversalof motion is accomplished by means of a clutchlever pivoted at the center, which is actuated by a cam-shaft in connection with reversinglevers and balance-Wei ght, the reversing-levers being connected by cords to treadles arranged alongside of the one above mentioned. These treadles are arranged in a group on the under side of an iron plate which is let into the floor, forming a level surface covering an opening through which they areintroduced, and hinged at one end to studs extending downward from the plate. About midway of their length are attached by links vertical slides extending upward,supported by guidesthrough the floorplate, terminating in a flat head or button. On one side of these-vertical slides are formed notches or detents, which engage with a projecting portion of the floor-plate, and are held in contact by a flat spring arranged at their back, and which allows of suflicient clearance to disengage the detents and permit the slides to move up and down in a'vertical direction, and be held in any portion of their travel by allowing the detents to engage by the action of the spring at their back. The upward motion of these treadles is efi'eeted by means of spiral springs,and the downward by the pressure of the foot, by which their action is controlled. They may be placed under the motion-transmitter, in which position they can be connected direct to the transmitter, or in any place most convenient to the operator, by introducing bell-cranks or direction-pulleys, making connections under the floor, and when not in use the slides can be pressed down and secured by the detents, so as not to form obstructions in the room on the floor. By this arrangement the operator can at any time reverse the position of the clutches, and by it the direction of motion or rotation, and can change the speed or can stop the entire machine Without interfering with the motion of the prime mover.
In order that my invention may be made more clear and better understood, .reference is had to the accompanying drawings, in which- Figure 1 represents a plan of the transmitter; Fig. 2, a side elevation; Fig. 3, an end view with one of the miter-wheels and a portion of the friction-clutch in section, showing their construction; and Figs. 4, 5, and 6 are views in detail of different portions of the machine. Fig. 7 is a vertical section showing the construction and arrangement of the treadle, and Fig. 8 a pulley to give direction to the transmission-cord.
Similar figures refer to similar parts in all of the views. j

I am aware that prior to my invention conical drums have been employed for transmitting a changeable motion, and that miter-gears, in
connection with clutches for the reversal of motion, have been in use and not new, none of which do I broadly claim; but
What I do claim as new and of my invention, and-what I desire to secure by Letters Patent, is
