VILLIAM MAIN, OF BROOKLYN, NEW YORK.
POWER-TRANSMITTING DEVICE.
SPECIFICATION forming part of Letters Patent No. 407,091, dated July 16, 1889.
Application filed June 13, 1888. Serial No. 276,986. (No model.)
To all whom it may concern.-
Be it known that 1, WILLIAM MAIN, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Power-Transmitting Devices, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.
The object of my invention is to provide a simple and compact device for transmitting motion from a power-shaft or the like to mechanism to be driven thereby.
My invention relates to the application for the transmission of power of what is known as the \Vatt sun-andplanet gear by means of mechanically-praetical mountings and 0011- nections in such manner as to impart motion to the driven mechanism only when the oscillating member of said gear is restrained to constant parallelism by means of a connec tion or guide extending from the oscillating gear to aguide-bearing, which guide-bearing moves with it when the power is not to be transmitted, but may be arrested or retarded, so as to throw the driving and driven mechanism into operative connection, and in such manner that uniformity of speed shall be imparted to the driven mechanism.
In another application, filed June 13,1888, Serial No. 276,082, I have shown and described a variety of mechanisms embodying my invention, and have explained at length the character of the said mechanism, generically considered.
My present application has for its object the protection by Letters Patent of my invention embodied in mechanism wherein the connection or guide governing the action of the oscillating gear-wheel consists of parts in which a swinging motion is combined with a sliding motion, both in a plane parallel to the axis of rotation of the driving-gear.
In other applications filed of even date herewith I have described and claimed specifically my invention applied in connection with the other types of guides mentioned in said generic application No. 276,982, and in still an other application, filed of even date herewith, I have claimed the method involved in the practice of my invention. The above-mentioned subject-matters I therefore do not claim in this application.
An important part of my invention, generically considered, and which I claim here in combination with the particular form of guide herein shown and claimed, consists of a bearing for the guide, which moves in unison with the driving-gear of the sun-and-planet series of gear-wheels, but which may be restrained or retarded, so as to throw the driving and driven mechanism into operative connection. The restraint or retardation of this hearing may be gradually accomplished by a frictionbrake or othersuitable device, and the power of the shaft and the momentum stored up in its rotating connections may be thus gradually and without shock or jar transferred to the driven mechanism.
111 the drawin forming a partof this specification and illustrating one general type of my invention, Figure l is a side elevation partly in section. Fig. 2 is a plan View partly in section. Fig. is a cross-section on the line A 13 of Figs. 1 and 2, and Fig. 4 is a crosssection on the line C I) of Figs. 1 and 2.
The shaft 1 is a driving-shaft adapted to be operated from any convenient source of power, and it carries fast upon it an eccentric 2, which moves freely within a circular opening in the oscillating gear-wheel 3,Which constitutes the initial member of the sun-andplanet series. Outside of and about this gearwheel is an annular gear-wheel 1, concentric with the driving-shaft 1 and rigidly bolted to a flange 5 upon the driven shaft 6, from which power is conveyed by any appropriate connection to the driven machinery,whieh driven shaft and connected driven machinery I term herein driven mechanism, the driven shaft being herein shown as illustrative of any form of driven machinery, to which the power conveyed through the gear-wheels may be applied. The oscillating gear-wheel 3 is provided at its outer end with a basal projection 7, carrying trunnion-pins 8. These trunnionpins have a bearing within lugs 9, projecting from a hollow two-part sleeve 10, said sleeve being provided at its outer end with lugs 11, swinging upon trunnion-pins 12, which have their bearings in the pulley 13. The trunnions permit the necessary swinging motion in one direction and also a sliding motion at right angles thereto. The oscillating gearwheel and the pulley 13 will maintain fixed positions relative to each other as regards rotation, their absolute relative positions changing as the shaft 1 revolves to the extent of'the swinging and sliding motions referred to by reason of the eccentric position of the gear 3 with reference to the axis of the pulley 13. The sleeve 10 constitutes in this mechanism the guide by which the oscillating gear-wh eel is connected to the guide-bearing represented in this mechanism by pulley 13, by the restraint of which guide-bearing the control of the oscillating gear-wheel is effected. Vhen thepulley 13 is free to revolve about its axis, the gear 3 is also free, and will convey no power from the shaft 1 to the outer gear 4. hen, however, the pulley is locked or held fast in one position, the gear 3 will be carried about by the eccentric in a position constantly parallel to itself, and will communicate to the outer geara rotating motion reduced to an extent dependent upon the ratio bet-ween the two gears. The amount of this reduction may be readily calculated according to well-known rules, which require no special explanation here.
In addition to the motions above referred to, therewilltake place also a longitudinal sliding motion of the oscillating gear itself equal to the distance between the middle point of the arc of swinging motion of the sleeve and the chord of said are. The movement of the oscillating gear will therefore be a'resultant of a movement in 'three planes. The line of the governing-points of the gear 3,Which in this case we may conceive to be the trunnions 8, is constrained to always maintain, as the gear 3 oscillates, positions of parallelism with reference to a fixed line, (represented in this case by the guides 14 ofthe pulley 13,) the mechanism effecting the constraint being the swinging sleeve 10 and its connections respectively to the oscillating gear-wheel and to the pulley.
Brakes of any suitable construction are required to control the pulley 13, in order to effect transmission of power through the gears, and I have shown two brake-shoes 16 applied to the pulley in Fig. 1.
It is true that that part of the mechanism which represents the line fixed in space, and which, for convenience,I will term a guidebearing, may be absolutely so fixed instead of having a motion; but it is desirable that it should be movable, in order that the power may be imparted to the driven machinery gradually and without jar. The preferable sort of motion for this part of it permits a convenient application of bralces, and thereby the speed of power-transmission may be varied within wide limits, depending upon the amount of pressure applied to the brakes. I
do not confine myself, however, in claiming this invention, to a movable or rotary guidebearing or the use of friction-brakes, but
have shown these several devices as convenient forms of construction. Neither do I confine myself to the particular form of those parts which constitute the connections between the oscillating gear and the guidebearing, since these forms maybe indefinitely varied while maintaining the double swinging and sliding motion in a plane parallel with the axis of rotation of the oscillating gear-wheel I wish it understood that my invention, claimed in the present application, embraces any form of mechanism constituting a guide, the parts thereof having a swinging motion in one direction and a sliding motion in one or more other directions, all of said motions being in a plane parallel with the axis of rotation of the oscillating member of a series of gear wheels, and connecting that member with a restrainable guide-bearing. I do not confine myself to that form of sun-and-planet gear in which the driving member is within the driven member. The driving member may be without, as in the original invention of YVatt. ted with an increase as well as with a reduction of speed, and the oscillating member may be the driven instead of the driving gear; nor do I limit myself to a sun-and-planet system in which there are but two gears. There may be intermediate gear wheels between the driving and driven gears, and the restraining mechanism may be applied to any one of these gear-Wheels.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
