ROTARY PUMP.

tending slightly beyond. the ends of the buckets proper and engaging recesses 24: formed in the discs 9. By virtue of this construction the buckets are allowed; to swing into and out of the pockets of the rotor while at the same time they arevretaine'd in proper relation to the rotor and the casing when the pump is in use. The discs 9 are secured to the rotor by suitable fastening devices as stud bolts 25. Each bucket is pro vided with a bolt 26 which is fast therein and extends through the slot 27 formed in a web 28 of the rotor which separates the pocketl9from a coredout place 29 in the rotor. Each of these bolts is threaded at its extremity remote from the bucket and provided with a nut 30 for purposes of adjustment whereby the outer edge 31 of each bucket is prevented from l'a'earing against the adjacent wall of the casing to produce undue friction.
My improvement consists in applying to the bolts 26 betwee'nthe buckets and the webs 28 of the rotor, spiral springs which are under tension to positively move the buckets out of the pockets into the space between the rotorand the inner surface of the casing, as soon as the buckets leave the abut- From the foregoing it will be understood that by the employment of the bolts and the springs, the buckets. are prevented from being moved outwardly against the inner surfaceof the casing with sufficient force to produce undue friction, while at the same time the sarings 32 act upon the buckets to liquid or fluid to move them outwardly and cause them to properlyperform their function even thoi 'l. therotor might be moving so slowly that the buckets would not open automatically by gravity and centrifugal force.
From the foregoing description the use and operation of my improvementwill be readily understood When the pump is in use it is so located that the water or other be pumped, enters the rotor chamber through the opening 10 and is discharged through the opening 12. lVhen the pump is in use the rotor is moving in the direction indicated by the large arrow in Fig. 7. As each bucket leaves the abutment 1d, it is caused to gradually open as the space between the rotor and the inner surface of the casing enlarges, this opening movement being positively effected by the spring 32, the bucket, however, being held by its bolt 26 in proper position with reference to the rotor and the inner surface of the casing to prevent undue friction as heretofore described. As the bucket leaves the inlet openings lO, it carries the liquid with it and finally forces it out of the opening 12 which is in communication with the conduit through which the water acted on by the pump is to be discharged or raised As soon as any bucket reaches the extremities of the crescent shaped members 13 adjacent the discharge opening of the casing, the bucket-s will be gradually moved inwardly into the pockets until the abutmentreached, and as any bucket passes the abutment it begins to open again by virtue of the recoil of its spring 32. It will be understood that the springs 82 might be employed to open the buckets in the absence of the bolts 26, in which event it would he nec-. essary to have recesses formed in the buckets of the adjacent webs 26 in which the extremities of the spiral springs could be seated. It is preferred, however, to use the springs in connection with the bolts for the reasons heretofore given.
I claim: I
1. A rotary pump comprising a casing a rotor therein having pockets, oscillatory buckets connected with the rotor to move into and out of said pockets, means for positively imparting the outward movement to the buckets and cooperating means for limiting their outward travel comprising bolts anchored in the buckets. and movable in an opening formed in the rotor.
2. A rotary pump cou'iprising a casing a rotor mounted therein having pockets oscillatory buckets mounted tb move in and out of said pockets and means for controlling the outward movement of the buckets comprising bolts anchored in the buckets and movable in openings formed in the rotor; means applied to the bolts for limiting the outward movement of the buckets and springs mounted on the bolts between the buckets and the walls of the potl'ets for positively in'iparting the outward i oveinent.
In testimony whereof I my signature.
