I'o all whom' it may concern:
Be-itkuown thatI,- WI'LLrAM H. GUILD, of l'Brokflym E. D., in the county of Kings and State of New York, `have invented a new and linproved RotaryfPump; and I do hereby de- `following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a' part Vof this speeilication, in which- Figure 1 is alongitudinal vertical'secton of myiuvention, `taken in the 4liuc x fr, Fig. 2.
` Fig.l 2` is an end viewof the same, Fig. 3, a
transverse vertical section of' thc same, taken Similar letters ol reference indicate jeorre- -spondingparts' inthe several figures.
This inventioncons'istsin the'employnient 4or usent awheel provided with spiral iangesz in the lineyy,Fig. 1. v
ora'rmsand fitted on a horiaontalshaft,which fisplahjedwtbin a cylindrical rase, and with h@ Wheel .arranged in such a manner that both have-a'proper-beariug and suitable pro- "sl-o'n; allowed 'fcr wear, so that the wheel .will
ffrtgtewithout-`anyloss from back action or`- -gl'eakage, and a very efficient, (simple, and c.c`o. n oinifc'al` pu mp obtained-one capable ofliftin g '.an'dlgforcing the water and operating.` without Ltheliability of-bceoming choked or clogged bysubsta'nces which maybe held in suspension in thewa'ter` or drawn up with it. 'To enable thoseskilled in the art to fully understand and coustr'uctvrny invention, lwi'll- -p'r0ceed to describe it.
-, A represents a horizontal cylindrical case -whiichis provided Witha proper base, B, and
has a cylindricaliange, C, at its upper part 'lt'o receive an eduction-pipe. The case Ais of cast metal, and itis not .of equal diameter throughout,'its induction end albeing smaller than the other part audadmitting of a shoulder, b, being within the cylinder, said shoulder extending circumfereutially all around the case.`
L J Yun. a snafu which is" fared longitudinally and centrally within the case'A, one end of theshaft-paSsingth-rough the head @which issecured to thelarge end of the case. The
opposite end of the shaft is fitted in ahead, `which is secured tothe smaller and indd ftion endfcf thccaseand works-ou a screw` renter, F, which passesr into aghub, e, at the center of the head d. The head c, at' the larger end of the case, is solid, so as to close it 'perfectlytight; but the smaller head, d, at the opposite end, is open to allow the water to pass freely into the' case.
On the shaft E there is placed'a wheel, G, which is formed of a hub, e', connected to a rim, f, by spiral flanges or-arms g. Three of these flanges are shown in the drawings, Figs.- 2 and 3; but more or less may be us'edj. The rim f is slightly inclined, and itssmaller end bears' against the shoulder b, asshown clearly in Fig. 1. The end-of the shaft E projects through the head c sufficiently farto adrnitof 'a'driving-pulley, g', being placed on it, and a lshoulder, h, is formed on the shaft,\vhich bears The operation is as follows: The shaft E is rol-ated by any convenient power,- and the case Amay be either submerged in the water to be elevated or an induction ppamay be attached to its smallerl'end. -The eduction-pi pe, which is attached to. the flange C, s hould first be fil-led with water, and. when the wheel G is rotated the suck-ing and forcing action cour lnences. The wheel in forcing the water through the'eduetion-pipe of course induces a suction in the induction-pipe or induction end of the case A. In consequence ot' the end ofthe rim f of the wheel bearing. against the shoulder b Within the case A, a complete eut-ofi' or partition is obtained-betwecugthe,induction and power or,e`ect in the operation by reaction or leakage is avoided, and in case' of -wear the shoulder the' screw point or center F being screwed a little'outward, and washers,if desirable, placedl on the 4shaft E adjoining the shoulder h. The action of the wheel itself, however, will have al tendency to keep its rim f in close contact with b.
I am aware that spiral or screw flanges have been used 4for raising water; but I am not aware that the same have ever been applied to orused in awheel arranged within a case 'having two different diameters, so as to form 'a 'shoulderro'r 4 I )cariug for the wheel, as herein against theiuner side of the head c, as shown ednction' parts of the case, and all loss of end. of the rim may be snugly adjusted to the I dolndtclaimtherefore, the employment or use of screw o r. spiral anges for thepu'r f'degi bearing;
