MEANS FOR OPERATING DRIVEN MECHANISMS.

Specification of Letters Patent.

Patented Jan. 30, 1917.

Original application filed December 7, 1914, Serial No. 875,860. Divided. and this application filed April 5-,

To all whom it may concern:

Be it known that I, Ronnn'r T. JENNEY, a citizen of the United States, and a resident of Monticello, in the county of Jones and State of Iowa, have invented a new and useful Means for Operating Driven Mechanisms, of which the following is a specification.

The invention relates to friction-clutches, to the. means for operating them, and to mechanism operable by or from the clutch members.

The primary object of the invention is to generally improve the construction and to increase the capacity, utility and efiiciency of devices of the same or a similar nature.

Other objects will presently appear. Some of these will be obvious and others will be specifically pointed out.

The invention consists, substantially, in the constructions and combinations shown in the accompanying drawings and herein described.

The above noted objects I attain by means, a preferred form of which is illustrated in said drawings, said form being identical with that shown and described in my c0- pending application, filed December 7, 1914, No. 875,860, for patent for corn-husker, ensilage-cutter, and silo-filler, of which the present application is a division.

It is to be understood, however, that while I have in the foregoing named application shown the herein described improvements in connection with Or embodied in a machine for performing certain operations on corn, the herein described means is applicable to any mechanism with which it may be operatively connected.

In the drawings above referred to: Figure l is a top plan; Fig. 2, an enlarged sectional I detail, partly in elevation; Fig. 3, an enlarged end detail, the pulley 9 removed and the shaft portion 6 shown in section; and Fig. 1, a detail of the yoke.

The exact construction of the preferred form of my improvements will be described in full herein, but I do not intend by describing the details thereof to be understood as limiting my claims in any way or manner thereto, the scope of the invention being pointed out in the claims hereto appended.

Considering the drawings in detail, and referring to each element and, where required, to each part thereof, by a distin-' Serial No. 19,386.

guishing numeral, uniformly employed, 22 indicate frame-bars which, it may be assumed, are parts of any suitable machine.

3 indicates a drive shaft mounted in bearings a secured by bolts 5 to said bars 2. One of its end portions is reduced or constructed, as indicated at 6.

7 designates the drive-pulley fixed on and driving said shaft, and 8 designates the drive-belt embracing said pulley and driven from any suitable source of power.

9 indicates a driven pulley constitutingone member of a frictionclutch presently more fully described. It is fixed by a key 10 on the constricted portion 6 of the shaft 3. The internal. and, relatively to the frame, inner face of its rim is beveled or flared, as clearly shown in Fig. 2.

On the reduced portion of the shaft 3 and bearing against the. shoulder 11 provided by reducing its end portion 6 is rotatively mounted a pinion 12 which is integral with an elongated sleeve 13 to which is secured by a spline 1d a friction-clutch head 15 the neck of which is provided with an annular groove 16. F riction-shoes 17 having each a beveled and rounded face 18 adapted to conform to the contour of and to friction ally engage the beveled. and rounded inner face of the rim of the pulley 9, are secured by bolts 19 and nuts 20 to the head 15.

20--20 indicate slots, one in the outer end portion of each of the arms of the head 15, and are adapted for the reception of the bolts 19, whereby the shoes 17 may be adi'usted relatively to the flange of the pul- 2121 designate adjusting screws, threaded each through and engaging the threads of a boss 22 and adapted to bear against the shoes 17.

23 indicates an expansion spring encir- 31 indicates a link crossing the frame 2 and pivotally connected at its ends to the shift lever 27 and bell crank 29.

32 designates a driven shaft mounted in bearings 36 secured by bolts 35 to the frame bars 2.

33 represents 'a spur gear wheel fixed on said shaft 32, and 34 indicates a s rocket or other wheel fixed on the same sha t. The wheel 34: is merely illustrative, and any other medium for transmitting motion from the shaft 32 may be substituted therefor.

Assume the parts to be in the relative positions shown in Figs. 1 and 2, in which the shoes 17 are in frictional engagement with the beveled concave face of the rim of the pulley or belt-wheel 9 and the wheels 12 and 33 in mesh. In this position the shaft 3 will transmit motion to the belt-wheel 9 (from which a driving-belt may be actuated) and the pinion 12 will drive the spur 33 and thereby the shaft 32 and wheel 34.

In order to stop the rotation of the wheel 9 the operator will throw the lever 29 to the dotted line position indicated in Fig. 1 to draw on the link 31 and thereby cause the lever 27 and collar 26 (through the medium of the pins 25) to shift the yoke 24: inwardly, to thereby retract the head 15 and shoes 17 in the same direction, overcoming the resistance of the spring 23 and withdrawing said shoes from their frictional engagement with the rim of the wheel 9. The portion 6 of the shaft 3 will revolve freely in the bore of the sleeve 13, and the movement of the pinion 12 will cease, thereby stopping the movement of the wheels 33 and 34 and the shaft 32, and, of course, any mechanism driven thereby.

The shoes 17 may be adjusted toward or from the inner face of the rim of the wheel 9 by suitable adjustments of the screws 21, and after such adjustments they may be locked by means of the bolts 19 and nuts 20. By moving the lever 29 but a short distance the shoes 17 will be drawn but slightly from the rim of the wheel 9, and the shoes will then act as a brake. It will be understood, of course. that any other driving means may be substituted for the belt-wheel 9 or the pinion 12, and that other driven mechanism may be substituted for the wheels 33 and 34 and the shaft 32.
