2 Claims. (Cl. 74-432) This invention relates to an improved means for transmitting power from a drive to a driven shaft. More particularly, th invention relates to a means whereby power is transmitted from a drive shaft to a driven shaft by means of a plurality of spokes constituting levers.

An important object of the invention is to provide a means of the type stated wherein power can be transmitted between the drive and driven shafts by a more simple method than the conventional meshing large and small gears.

Another type of object is to provide a means of th type stated which will effect the power transmission without loss of speed, as compared to power transmission means of conventional types.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is a section through a power gear constructed in accordance with the invention, taken substantially on line Ii of Figure 2.

Figure 2 is a section substantially on line 2-2 hollow shaft or bushing I I]. The bushing I is mounted in a suitable bearing or support I l.

Diametrically opposing and in line with the spoke I, is the extension I 2, which like the spoke, is preferably integral with the collar 9.

The extension I2 is secured by pin Hi to a small wheel l4, slotted as at IE to receive the pin, thus to allow a free action connection. A spacer sleeve I6 is interposed between the extension 12 and wheel 14.

Wheel i4 is fixedly secured to a power shaft l8, as by a key I], and drives said shaft.

A spoke i9 is secured to thering gear 5 in the same manner as spoke 'l, and has a collar 20 underlying the collar 9. Spoke I9 is formed with an extension secured to the wheel l4. Another spoke 2| is also secured to the ring gear and has a collar and extension like the spokes previously described. It also is secured to the wheel II.

The power shaft l8, for purposes of illustration, is shown as having mounted thereon a pulley 23, to which rotation can be transmitted.

In operation, on rotation of the ring gear 5 by th drive gear 6, power is transmitted through the spokes I, I9 and 2| to the small wheel II. By reason of the construction illustrated and described, the spokes act as levers. with the power being transmitted to the wheel I4, and thence to the power shaft 18. The small wheel and power shaft l8 thus turn the same number 01 revolutions as the ring gear 5, and the power is transmitted with case because of the leverage exerted through the spokes. Each spoke. as will be apparent, transmits power through and beyond the axis ,of the power shaft l8, before impres ing its power on the marginal portion of the wheel 14.

In conventional gear arrangement, there is a drive shaft which is driven by a power sou cc such as an internal combustion motor. Through the gears, power is transmitted from the driv to a driven shaft. Still considering conventional structures, assume that the motor while operating at a certain speed is accelerated to speed up the rotation of the drive shaft, for the purpose of speeding up the rotation of the driven shaft. There is a time and power loss, perhaps infinitesimal, before the driven shaft is operating at the increased speed.

The gear structure illustrated and described herein is intended to make it easier to impart the higher speed rotation to the driven shaft.

What is claimed is:

1. In a gear wheel structure a toohed ring, spokes connected at one end to the ring, collars on the other ends of the spokes, said collars being superposed and concentric with the ring, extensions on the collars aligned longitudinally with and diametrically opposing the respective spokes, and a wheel movably connected at locations upon its face spaced circumferentially of said wheel to th respective extensions, said wheel being concentric with the ring.

2. In a gear wheel structure a, toothed ring, spokes connected at their outer ends to the rin and extended inwardly and radially thereof, superposed collars concentric with the ring and integrally formed on the respective spokes intermediate the ends of the spokes, said collars being closer to the inner ends of the spokes than to the outer end, a wheel concentric with the ring and collars, and connections between the inner ends wheel.
