FRANCIS M. BOOKWALTER, OF SPRINGFIELD, OHIO.
HYDRAUUC NozzLE.
SPECIFICATION forming part of Letters Patent No. 551,575, dated December 17, 1895.
Application filed March 2 7, 1895.
.To all whom, itmwy concern:
Be it known that I, FRANCIS M. BooKwAL- TER, a citizen of the United States, residing at Springiielchin the county of Clark and State of Ohio, have invented certain new and useful Improvements in Hydraulic Nozzles, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to certain new and useful improvements in hydraulic nozzles, and it is especially designed for use in connection with hurdy-gurdy water-wheels, though applicable to other purposes.
My improvements have reference to a waterjoint between the fixed and movable sections of the nozzle and to central columns forming the point of bearing between the two sections, and to a central pivot through-bolt, and also preferably a spring to maintain and regulate the bearing between the sections, all as hereinafter more fully described.
In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure 1 .represents a longitudinal axial section of my improved nozzle; Fig.' 9, a partial elevation and partial section on the line a: of Fig. l, looking in the direction of the arrow; and Fig. 3, a like view to Fig. l with the central bearing-columns in contact at one side of the division-line instead of on said line, as in Fig l.
The letter A -designates what I term the iixed section of my nozzle,which has a flange B forl connection with the pipe that conducts the water. This section has an annular facedoft part forming a plate C, provided with a series,three in the present instance, of annular grooves I). It is further provided with a column E whose axis is coincident with the axis of the grooves D. 'A stuffing-box F is formed on the outer side of the section A, and a central pivot through-bolt G is fitted to the column E and provided with a shoulder which forms a gland H to pack the stufiing in the box F.
The other section of the nozzle, which I term the discharge-sectiom7 is shown at I, and is provided with a faced-off part consti- 5o tuting a plate J, corresponding with the plate O. The plate J has a series, three in the pres- Serial No. 543,372. (No model.)
ent instance,of ribs or beads K, which are annular and match with the grooves D in shape and position, but are slightly smaller, so as to leave the merest space between the ribs and the grooves into which the water fills and forms a water-joint or packing. IIhis space is marked L and is shown as existing between the plates O and J, both inside and outside of the grooves and ribs. It will be observed that the ribs and grooves give the space L atortuous path with right-angle turns or changes of direction. Such sharp turns prevent the water from flowing and leaking, while the water constitutes a self-packing as well as practically frictionless joint between the stationary and discharge sections of the nozzle. The section is further provided with a column M corresponding in position with the column E, and fitting end to end against it, and forming what I term the central bearing between the two nozzle-sections. In Fig. l I have shown the point of bearing in line with the division between the nozzle-sections, while in Fig. 3 the point of bearing is at one side of such division-line, rendering one column longer than the other. Accordingly I wish it to be understood that this central bearing may be located at any point within the interior of the nozzlesections, but preferably as shown in Fig. l. The axial line of this point of bearing is always,however, coincident with the center from which the ribs and grooves are struck. A stuffing-box O is formed on the outer side of the section I, and a gland P is fitted to it to bear upon the stuffing and also to resist one end of a spring Q which encircles the pivotal through-bolt G, and is more or less compressed by a nut R on said bolt, with an intervening washer S. Thus the degree of pressure between the columns at the bearing-point is regulated by the tension to which the spring is subjected, while the spring affords a constant and uniform pressure, 4automatically taking up the wear and also sufficiently yielding to permit of the ready turning of the section I to change the direction of the stream.
Thus my improved adjustable nozzle has a IOO shoulder on the bolt to form a gland for one box, a separate gland on the bolt forthe other box, a spiral spring on the bolt and fitting against the latter gland, and a nut on the bolt acting against the spring, there being a thin space between the meeting faces of the plates and the grooves and ribs.
In testimony whereof I my signature in presence of two witnesses.
