`In the useV 'of-.my improved controlling i mechanism, it will be noted that. vwhen the operating handle 35 is rotated the internally threaded nut'member 31, engaging'the threads formed on the cylindrical portions 29 and- 30 or-the rods .24 and 25, will react against the shoulder. 39 of the frame through -tlie'sleeve member 40 and will thus cause the rods to siinultaneouslymove in opposite directions,thereby swinging the V-shipper members and V6 about their pivots 7 and Sinopposite directions and causing one of the friction'al controlling members `tov-be released while the other is applied,
consequently;- preventing the application of both the' clutches, and consequently the fast or slow feeds, simultaneously.
As a-result of myv improved construction, it will be noted that I havev provided `an i `improved, controlling mechanism for selec- 'tively operating a`plurality of clutches and which has'a` common operating element of improved -form which is readi-lyaccessible 'Y 4from the exterior ofthe machine frame for assembly. and adjustment'. Itr` will further benotedthat I have provided an improved rcontrolling mechanism of exceedingly-siniple, rigid, and compact construction, y.which lmayVV beapplied to amining machine of 25 standard Aform with a minimum of change and eXp ense.

While I have in this applicationy specifically,` described one formwhich my invenytion may-assume in practice, it will be understood that this'formof the same is shown for purposes of illustration and that the invention may be modified and embodied in variousF other forms without departing from 'its'f spirit' orhthe. scopel of the "appended claims.l v i s What I claim as new and desire to secure by Letters Patent is:V
