T0 a/ZZ whom, t may concern:
Be it known that I, FREDERICK S. KEYES, a citizen of the United States, and a resident of Warren, in the county of Worcester and State ot' Massachusetts, have invented a new and Improved Transmitting Mechanism, of which the following is a full, clear, and exact description.
My invention relates to mechanisms for transmitting power, and more particularly to those by which the energy may be stored and its action modiiied.
It consists in the various features and combinations hereinafter described and more particularly claimed.
Reference is to be had to the accompanying drawings, forming a part of this specification,
in which similar characters ot' reference indicate corresponding parts in all the views.
Figure 1 is a top plan View of one embodiment of my invention, parts being in section. Fig. 2 is a transverse section therethrough on the line 2 2 of Fig. l. Figs. 3 and 4 are perspective views of opposite sides of one of the transmitting members, and Fig. 5 is a diagrammatic view illustrating an application of my invention.
I have here shown a shaft 10 rotatable in bearings 11 and carrying a driving member in the form ot' a wheel l2. This wheel may receive power through a belt-surface 13, projecting from its outer side, and over which passes a belt 14 to a pulley 15, fast upon a driving-shaft 16. The wheel 12 has a central hub 17, which may turn loosely upon the shaft, it being' prevented from moving longitudinally thereof by collars 18, fast upon the shaft at its opposite sides. This hub, as illustrated, projects from the wheel at the opposite side from the belt-surface and has at its outer extremity with respect to the Wheel itself and its inner with respect to the system as a whole an annular flange 19. Connecting this flange and the wheel is a cylindrical wall 20, which is divided near its center by a continuous opening 21, leading to a chamber 22, formed by the liange and wall about th hub.
At 23 the iange 19 projects beyond the Wall 21 to furnish a contact-surface.
At the outer edge ofl the wheel surrounding the hub is a peripheral flange 24, and at the extremity of this flange in alinement with the flange 1 9 and projecting toward it is a iange 25, furnishing a contact-surface and forming, With the body of the wheel, a
channel. Between the hub and ange 24 is a generally radial abutment 26, which may becast integrally with or fixed to the wheel and which projects inwardly from the periphery, it terminating outside the hub. This abutment may be braced at one side by a series ot' Webs 27.
Extending in substantially radial lines from the hu b are a plurality of movable abutments 28, projecting into the peripheral channel, and
each having a reduced portion 29, which enters the opening 21. These abutments also serve as connecting members between the sections of circularly-arranged spiral springs 30, lying concentric to the hub. It should be noted that the division of the springs into comparatively short sections connected by the guided abutments, while not very materially decreasing their length, retains them in position and prevents their displacement or buckling and their thus oiiering frictional resistance tomovement. These springs extend between and are supported by oppositely-placed bosses 31, which project toward one another from the adjacent faces of the abutments. The abutments 28 are guided in their movement without introducing appreciable friction by rolls 32, mounted to lrotate upon projections at each side of the inner and outer extremities of the main portions of said abutments and contacting with the inner face of the wheel and with the flange 25 and the portion 23 ot' the inner Harige. The outer rolls at each side are in pairs, they being supported upon lateral extensions 33. Their separated points of contact serve to prevent their turning axially under the stress of the springs. At opposite sides of each abutment extension 29 are rolls 34 34, which contact With the inner surface of the wall 2O and hold the abutments against outward displacement, they taking this component of the thrust of the springsections.
With the last of the movable abutments of ,the series, or that adjacent to the iixed abutment, contacts a set of studs or projections 35, here shown as three in numbeigcorresponding to the series of springs. They extend from the inner side of a Wheel or intermediate member 12, which at its opposite side may be in all respects similar to that just described. As illustrated, there are three of these Wheels 12a; but any greater or less number might be used. In fact, it Will be obvious that instead of cooperating with the abutment of the last Wheel 12L the driven member IOO IIO
might as well, save as to the degree of spring action secured, act directly with the wheel 12. By the Ldriven member I mean any part which is driven by the transmitting mechanism, and it may include the shaft 10 and a wheel 36, keyed to the shaft 10 by means of a suitable hub and having studs 37 projecting from its inner side and in the present instance contacting with the last movable abutment of the adjacent wheel l2, as do the projections of said wheels with those adjacent to them. The wheel 36, with its projections 37, therefore constitutes a companion member for the adjacent wheel 12a to transmit power therefrom to the shaft 10.
In Fig. 5 of the drawings is shown one application of my invention. Here the wheel 12 is provided with ratchet-teeth 38, engaged by a relatively stationary pawl 39. The direction of inclination of the teeth is such that the springs of the mechanism are prevented from reacting upon the driving member, they being capable of exerting their effective tension to rotate the driven member only. The shaft 10 is provided with a cone-pulley 40, overl which and a similar pulley 41 upon a driven shaft 42 passes a governing-belt 43. With this belt cooperates the lever 44 of a governor 45, of any convenient type and which acts to shift the belt upon the cone-pulleys to equalize the rotation of the driven shaft in the usual manner. There may also be associated with the wheel 36 a series of ratchetteeth 46, with which may cooperate a pawl 47. By throwing this pawl into engagement with the teeth the driven mechanism may be locked and the entire power of the driving member applied to compress and store the energy of the springs 30.
'Ihe connections in which my invention may be used are manifold; but among' the more useful is its employment to securea coordination of the eifects of vmotors-such as wave, wind, or explosivein which the action is irregular. Here the springs absorb the excessive impulses and enable them to be applied during periods of diminution of power. It is applicable to the coupling of motors of unequal power and is useful as a storage mechanism in connection with wind-motors and other sources of energy in which the power varies or at times ceases altogether. In -any event it will serve as a cushioning means between the driving member and that driven, taking up any shocks which would otherwise be transmitted.
Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. The combination with a driving member and a driven member, of a plurality of circularly-arranged springs for transmitting power between the members, each of said springs comprising a plurality of independent sections.
