i To all whom lit mayoncern Be it known thatii, EDMUND KEITH, of the city of4 ment, with one-half the caseremoved, to showthe interior. p i
Figure 2 is a section in planea x`of fiv. 1. Figure 3 is a perspective view of' one-half the case y and one of the revolving wings for paddles.l
Like letters of reference indicatecorresponding parts inall the ligureS.
improvement belongs to that class where wings or paddles, situated in a case, lturn broadwise when just 'forward ot'A the induetionnlet, but turn tlatwise when just past the eduction-outlet, to" allowthem' to` pass the butinent- `that arrests the revolution of water.
My invention consists in imparting to the wings or paddles `a vconstant forward revolution, by means i hele-titer` described, in'steadzof` an alternate `vibrating movement, back andv forth, duced in pumps of this kind.
1n the drawingr- A indicates a case, made `of halves, suitably bolted together, and provided with induction and yeductionpipes b c. p
One-half of vthis case has formed on the inside, between the pipes, an extended llat bntment, d, as clearly shown,` and also around the centre, two concentric such as is usually procam-waysf f', opposite each other, occupying respectively the segment of circles, the one being of larger diameter than the other.
` Oloselyinside the case fits acylindrical piston-head, B, with shaft g, bywhi'oltit is operated.
This head has a central hub, h, and a concentric` flange/5, which stands outside the cani-ways ff', thus enclosing them closely, and leaving an openannular space, k, between the hub andilange.
W'ingsor paddles C (l, tilling the cross-area of` the space ofthe case, are connected with the piston-head, so as to turn freelyon their axes. i
To secure this result properly, the axis 1 of" each, passes. through ilange t and enters hub h, as clearly shown in fig. 2. A
This axis has two cross-arms, m m', resting in annular space k, and coincidingiin position respectively with cam-ways f f', which they strike in their passage.
I t will belseen that the butment is of such an extent thatsone wing does not leave it until the next comes on, so that the open space over the top of the butment, through which the wings pass flatwise, is kept closed at all times against the unnecessary escape of water. v
, Before one wing leaves, the next strikes on, and
the only escape of water is' the small space intervening between the wings.
The wings in section are wedge-shaped, by which they tit more accuratel y between the butment and case ,in passing iiatwise.
The operation will be readily understood.. As the piston-head is turned, the cross-arm m,
.striking the corresponding'way f, causes the wing to turn broadwise across the area of the ease, just past the induction-pipe b,fin which position it remains till" `therevolution carries it just pastthe ednction-fpipe,
lwhen armmV frees from Way F, and the other arm,
m', then strikes corresponding way f', and the/wing or paddle consequently turns forward a quarter revotion i'latwise, in position to pass over dat butment ll.
The axial revolution of the wings is constantly for-V ward, and never backward.
Itnnatters not, however, which way the piston is turned, as the action isth'e same either way.
I am aware that in rotary pumps there are cases in which the wings t-urn tothe right-angled position, to accomplish the saine general object as' above indicated, but in such cases, so far as I am aware, the' Wings do not have a constantly forward revolving n1otion on their axes, but-rather an alternately vibrating forward-and-back action, lirst turning up to close-the passage, and then turning down to open it'. Such is `the case in patent No. 56,627, of 1866. l
The great diilicnlty in such cases is, thatpif the wings get clogged with sediment or other matter, in breweries, for example, they cannoigby having only a partial movement, free themselves, but hold the clogging-matter and carry it around andaronnd. i Another diflieulty is, that in changing position the back motion acts against thc current, andselves to check it, whereby there is loss of power, aswell as eiiect. f 1
lhe particular arrangement of. the cross-,arms m m vand cam-ways f f are eli'ective in producing this result, and asV these parts are very simple `in their construction, and are not liable todisarrangement,.and
being perfectly enclosed by the piston, they cannot become obstructed.
This invention' is e ual-llr a licable'to )um )s Wa- D l l i What I claim as my invention, and desire to secure by Letters Patent, is-
The nrrmigement with the case A and pafddlesC, of the enclosing piston-head B, with the ange i, enclosing fthe operating-parts, consisting of the eamvwnys ff :md cross-arms m m', the whole operating in the mamner z und for the purpose specified.
Also, the combination, with the case A and paddles C, of the Het extended butment d, on one side of the case, and serving the double purpose of aiv stop to the water and a guide to the paddles, as described.
In witness whereof, I have hereunto signed my naine, in the presence of two subscribing witnesses.
