Specification of Letters Patent.
Patented July 27, 1909.
Application filed. October 4, 1905. Serial No. 281,310.
To all whom ii-may concern:
Be itv known that we, Ronnn'r ll'IOFARLAND DOBLE and Am nnn ROSEN'IHAL, both citizens of the United States, and residing at San "Francisco, in the county of San Francisco motors in which a jet is thrown against the blades of an impact. wheel, and our invention consists in the constructimi and arrangement of the dcflector by means of which the jet is controlled to regulate the speed, as fully set forth hereinafter, and as shown in the accompanying drawing in which-- Figure l is tllI-QlQVtltiOIl, in part section, of suflicient of an impact motor to illustrate our invention; Fig. 2, part of the same, the parts in a different position; Fig. 3, an end view of the nozzle and deflector; Fig. 4, a
sectional view showing a deflector in the form of a. grooved block instead of a tube; Fig. 5, an end View of the deflector of Fig. 4.
The wheel A, its blades a, the nozzle B, and the governor G, may all be of usual or any suitable construction. The deflector C, instead of presenting a flat face as in some other constructions has a face curved or grooved transversely that is, (JOI'I'QSPOIKliIIg as nearly may be to the cross sectional form of the As a result of this construction the said face instead of spreading or dispersing the jet. has the effect of preserving to a greater' degree the proper form thereof. :It is important that the curved face of the deflector should correspond to a cylinder; that is, it should be of such a form as to present a straight line in longitudinal section as otherwise, instead of deflectii'ig th stream, it would cause it to spread beyond the deflectorto a fan shape, a result which would render it. absolutely inoperative for p Tactical purposes. \Vhilo a block with a groove of proper form and size may be used,
as the jet contacts with the deflector at only one half its circumference, it, is preferable to form the deflector in the form of a hollow cylinder, or sleeve or tube, as this permits the tube to be turned in its support. to present different parts of its face to the et, and when onc.part is worn another can be brought into position and the tube can be thus utilized until worn away. A further and even greater advantage is that the deflector of cylindrical form can be made of special hard material, such for instance as manganese steel, capable of resisting corrosion to a great degree, and as-such hard material can be machined practically only by grinding. the hollow cylindrical form lends itself to this mode of manufacture.
' 'hile the grooved or hollow deflector may be supported and adjusted in different ways it is preferably secured in a pivoted arm or support E, so as to occupy a position with its axis ct-iinciding with that of the jet when the latter is not deflected, the deflecting face being carried into the jet at an angle to deflcct the As shown the deflector is carricd into the jet from above, so that its edge verges from the nozzle and meets the jet, and therefore it has no tendency to fall away fronrthc jet in case of lost motion, or to be drawn into the jet by the action of the latter. As shown, the deflector fits a socket in the arm E and the latter is carried by a rock shaft /1 the arm or support E bcing'operatively yonnected with the governor in any suitable manner so that on an increase of speed the deflector will be carried at an ngle into the jet. The rock shaft is shown as mounted in a bracket which is bolted to the nozzle.
'0 do not claim as our-joint invention a deflector carried from above so that the edge farthest from the nozzle first meets the jet.
\Vithout limiting ourselves to the construction shown, we claim 1. The combination with the Wheel and its bucket of an impact water motor, of a nozzle and a deflector having a transversely curved deflecting face, and a support pivoted below the jet and adjustable to-carry the deflector into and across the jet at an angle thereto, substantially as set forth.
2. The combination with the wheel and its bucket of an impact water meter, of a nozzle, and a deflector having a face curved to conform to a cylinder, and a support for the deflector supporting it movably in a position for the curved face to be brought from abovc'the jet at an angle thereto to deflect the same downward.
i E). The combination with the nozzle of an impact motor, of a movable deflector support and a deflector carried thereby and separable therefrom and having a cylindrical opening thcrcin, substantially as sci forth.
4. The combination with the nozzle of an impact motor, of a movable deflector sup-,
, port and a deflector carried thereby and having a circular orifice and .rotatabiy' adjustable in the support, substantially as set forth.
The combination with the Wheel and its bucket of an impact Water motor, of a nozzle, and a deflector having a face curved to conform to a cylinder, a support for the deflector supporting it movably in a osition for the curved face to be brought rom above the 'et at an angle thereto to deflect the same ownward, and. a governor connected to swing the deflector to, yary its an 1e 5-,- to the jet according to the variations oft 6 load. v
6. The combination with the nozzle of an impact motor, of a bracket connected thereto, a deflector support pivoted to said bracket,
seams angle thereto for the'purpos eset orth.
in testimonyfwhereof we have signed our 2 names to this specification in the presence of- 4 two subscribing witnesses.
