citizen of the United States, residing at Green Mountain, in the county of Marshall and State of Iowa, have invented certain new and usefnl Improvements in Governors for Stacker- Blowers; and l do declare the following to be avfull, clear, and exact description of the invention, such as will enable others skilled in the art to wh ich it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters of reference marked there on, which form a part of this specification.

My invention relates to anew and novel sufficient toforce the straw therefrom. This` disadvantage frequently necessitated the `clearing of the fan-box or premature stopping of the'niachine.r l

The primary object of the present invention isthe provision of mechanism whereby the fan at the starting or slowing up of the operation is caused to rotate through the medium of intermediate mechanism relatively faster than the pulleythrough which the power is transmitted and in the provision of additional mechanism whereby such intermediate mechanismmay be automatically thrown out of operation When'the fan has reached a certain velocity, so that the fan will be caused to rotate lat the samespeed as the power-transmitting pulley. 'In the accompanying drawings an embodiment of the invention is delineated for-the mere sake of illustration, and when the same is hereinafter referred to like letters of reference will designate corresponding parts in the several views. Y

Figure l is a plan view of a construction AReferring morespecitically to the'drawings,A designates a suitable frame, upon whichthe fan-governing mechanism `hereinafter described issupported, such. frame being suitably attached to the side of a stacker, as shown in Fig. 5, in such position that it maybe operated by a belt running froma cylinder-shaft or other portion of the main machinery on the stacker.

`B is a horizontally-disposed shaft mounted in suitable boxings at opposite sides of the frameworkl A and having an elongated por.- tion extending outwardly from one end and carrying afan C ot' any suitable or preferred construction, which is located and operated in u the stacker-bodyy in the usual manner. Upon this shaft is loosely mounted a pulley D, which I will term the power-transmitting pulley. This `pulley is Vdesigned to impart motionto the shaft B through the medium of a clutch D', the pawls or dogs d of said clutch being carried on the side of said pulley and the ratchet or toothed portion d' of the same being keyed to the shaft in a casing Zand adapted at all times to turn with said shaft.

At the endof the framework opposite that in which the pulley C is mountedis rotatably mounted in similar boxings a thegoveiner-shaft E, upon which is mounted the governor E', comprising a pulley e, springarms e', balls e2, connecting-links e3, and the sliding sleeve e4. The pulleyof the governor is adapted to contact with and be operated by the same belt that operates the pulley D, Fig. 5. The sleeve e4 is provided with a peripheral groove e5, which is engaged by the end of a lever F, pivoted at f to the brace-rod G. At

, a point intermediateits ends the lever F carries a pivoted link F', which link in turn is pivoted at its opposite end to a second lever F2, which is pivotally secured to the bracerod G2 and extends rearwardly and is formed into the bifurcated portion f2. cated portion of the link F2 engages a peripheral groove h in a clutch-carrying sleeve H2,

This bifurl IOO loosely engaging the shaft B and keyed to the gear H', which. is also loose upon the shaft l2.`

From opposite points. on the clutch-sleeve project pivoted clutch-shoes h', adapted to contact when in operative position withjhe Y.

To the side ofthe gear II" is a relabe rotated at a speed' much greater than that ofthe operatingpulley and sufficient pneu. maticlforce` created thereby to, at all times keep itself and its box clear of anystraw or other,.material which would ordinarily accumulate and clog or interfere with the oper- A- ation of the fan in its-initial or slow-down movement tively-smaller gear H, loosely mounted on the shaft B and capable, of rotation independ# entiy of the gear H. Located forwardly of the gears .H and H are gears K K', secured' together andiadapted` toturn"simultaneously.,

The gears K K" are adapted to.mesh,1:espec tively, with the gears H H", the gear K' being relatively larger than the gear K'. These gears are suspendedinithe proper positionby' the bracket L, which` is in turnf bolted or4 otherwise secured to the brace-rods fGr' and'- Gr.21A The gear H' has formed'i-ntegral therewith a cup k, carrying pawls or dogslc', simi:-y
