SENECA L. BERRY, OF SUNNYVALE, CALIFORNIA.

HYDRAULIC GIANT.

Specification of Letters Patent.

Application filed January 24, 1910.

' To all whom it may concern:

Be it known that I, SENECA L. BERRY, citizen of the United States, residing at Sunnyvale, in the county of Santa Clara and State of California, have invented new and useful Improvements in Hydraulic Giants, of which the following is a specification.

This invention relates to hydraulic giants. Its object is to so design and construct water nozzles of this class that a much more effecthe construction and combinations of parts in section.

as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a side elevation of the monitor. Fig. 2 is a plan view of the ball-joint partly in section. Fig. 3 is a side elevation Fig. 4 is a cross section of the nozzle.

2 is a stationary elbow section; 3 is a complementary elbow, .turnable horizontally about avertical pivot or king bolt 4, and having a ball and socket connection with the nozzle 5, which latter turns in a vertical plane about horizontal pivots 6. The base of the section or elbow 3 has an outwardly projecting flange-7, against which a packing ring 8 is held by a clamp ring 9 adapted to rest upon a complementary annulus or shoulder 10 formed upon the horizontal edge of the stationary elbow 2. Preferably the lnner surface of the flange 7 is turned off so as to form a recess 11, and the ring 8 being of sufficient width to cover the ridge 12 of the section 2 when the giant is in use, water pressure will force the gasket down tightly upon the ridge 12, thus effectively preventing leakage at this joint.

In order to facilitate horizontal turning about the king bolt 4, suitable anti-friction frustro-conoidal rollers 13, Fig. 3, are intro- .duced between rings 14 and 15 surrounding the bolt 4 and just beneath nut 16. Thus the thrust of water pressure in the elbow 3 is borne by the conical rollers 13 and the nozzle may be easily turned from side to side.

Serial No. 539,808.

An important feature of myv invention resides in the particular means and method of connecting the nozzle 5 to the elbow 3 so as to greatly reduce the tendency of the water entering the nozzle to form eddies, which latter greatly lessen the speed of discharge as well as cause the water to swirl and separate as it leaves the nozzle.

It is essential in hydraulic giants to provide means whereby the nozzle may be moved in a vertical plane in conjunction with the horizontal swing, and this is commonly accomplished by securing the nozzle to the elbow by a ball and socket joint in which the socket is formed on the nozzle and the complementary ball is made on the elbow, which thus produces an enlarged chamber at the inner end of the nozzle into which the water is discharged from the comparatively smaller passage in the globular elbow. By this old construction the water forms numerous eddies and counter-currents which check the flow and cause it to swirl and separate immediately upon leaving the nozzle. It is to improve .on this very defective form of joint or connection and to prevent the formation of eddies and obtain a more compact jet of water, that I have clesigned and employ a ball-shaped joint section 17 removably attached or in any suit able manner united to the nozzle 5 and fitting a corresponding ball-seat 18 on elbow 3. That is to say, in my construction my nozzle fits into the elbow, while in the old style giant the elbow fitted into the nozzle. The nozzle is movable upon the pivot pins 6, which screw into lugs on a metal ring 19 bolted to a flange 20 on the socket-elbow 3 and clamping thereon a packing-ring 21, Fig. 2. The bore of the nozzle 5 is practically of the same diameter throughout its entire length, and therefore the water is permitted to flow evenly, smoothly and unchecked through the joint from the elbow 3, and no detrimental currents are set 11) in the nozzle to reduce the effectiveness 0 the jet issuing from the nozzle, which may be tapered if desired. To assist in overcoming the thrust due to the use of water under high pressure, appropriate means are employed to partly relieve the pins 6; straps 22 being secured rigidly to a flange 24 on the nozzle and pivoting about the pins 6, and U-bolts 25, secured in the elbow flange 20, are passed through ring 19 and around the lugs in ring 19 into which the pivots 6 screw.

The several oints of the sections are suitably packed by the gaskets 8 and 21; and a particularly efficient means of packing against leakage at the king-bolt in the elbow 3 comprises an inverted flexible ring 25, Fig. 3, of suitable packing material of inverted U-shape, the outer side of which seats in an annular recess 26, and the inner side bears upon the bolt 4. Consequently, water under pressure may reach the under side of the ring 25 and expand the ring sufficiently to snugly seat upon the supporting surfaces and so prevent leakage at this juncture; and to further insure against leakage here a gasket 27 is interposed between the roller bearing-ring 15 and the top of the elbow 3.

In connection with the interior ball and socket arrangement of the nozzle, I so construct the nozzle that no rivets are presented on the interior, and there are no lap seams exposed; this smoothness and freedom of projections being accomplished by forming the nozzle 5 of a plurality of longitudinal cylindrical or tapering segments 28 of curved crosssection and having radial flanges 29 projecting exteriorly and riveted together, reinforcing strips 30 being adopt ed when desired.

As a further means of preventing swirling and eddying of water in the nozzle 5, I insert the longitudinal strips or vanes 31 between the adjacent flanges 29; these vanes extending parallel to the flow of water and projecting radially into the nozzle bore so that they act effectually to prevent the formation of counter-currents and also serve to stiffen the nozzles.

One very important point of this invention is the arrangement of the ball socket in a double jointed giant. It has been customary to put the ball on the upper casting. This passes the swiftly moving water from a smaller to a larger section suddenly, resulting in eddies and stream disturbance which seriously affect the jet issuing from the nozzle. In the arrangement shown it is easy to arrange a good waterway and to make whatever section changes that are necessary from the larger to the smaller, which is attended with less loss and disturbance to the stream. The second point is the spout construction shown. The object is to obtain smooth surfaces inside, free from rivets and with straight, true vanes, the latter being required to prevent any tendency to swirl which may arise when the water makes the turns through the elbows. These vanes are usually made of angle iron and riveted inside of the spout, and the spout is usually of the same construction as riveted steel pipe and more or less rough. Beyond these two main features are the features of the ball section 17 fulcrum pin, its U-bolts 25, the supporting straps 22, and the roller bearings on the king-bolt.

Having thus described my invention, what I claim-and desire to secure by Letters-Patent, is:

1. In a hydraulic giant, the combination of an elbow section having a socket, a nozzle with a ball to fit the socket, the socket having an outside annular flange, a ring bolted to the flange with a packing secured therebetween, which packing bears on the periphery of the ball, the ball having recesses and pivot pins fitting said recesses and screwing into said ring which is secured to the flange, and U-bolts passed through'the ring vand flange and embracing said pivot pins.

2. In a hydraulic giant, the combination of an elbow section having a socket, anozzle witha ball to fit the socket,the socket having an outside annular flange, a ring therebetween, which packing bears on the periphery of the ball, the ball having recesses and pivot pins fitting said recesses and screwing into said ring which is secured to the flange, U-bolts passed through the ring and flange and embracing said pivot pins, and straps on the outer ends-of said 3. In a hydraulic giant and in combination with the elbow section thereof, a-nozzle made up of a plurality of longitudinal cyradial vanes within the nozzle.

In-testimony whereof I have hereunto set my hand in the presence of two subscribing 'wltnesses.
