To all whom 'it may concern:

Be it known. that l, W'mnn CLAUDE JOHN` son, subject of the of Great- Britain,

residing at Brofldstone Ferm, Colemans hiffh velocity' throiwh a nozzle which is so` b l? y mounted as to be adapted to undergo ffradn ual angular deviation, alternately-ir .n 'and' 20 towards a vertical lino, while tipe piane ci .iangular movement oi the axis of the nozzle rotates continuously about a vertical airis at the centerof the. oi distribution. On the ratio adopted of the period'occupied by the swing to that of the rotation, will depend the form of the path wetted by the continuous stream yoi' water. -rlhat which will elieet 'the gradual covering Voi the en` tire area or surface to be watered, in e mann ner involving the leastv movement of the 'parts of the machine will. be such that the wetted path isa spiralot gradually increas ing, alternated with gradually diminishing radius, in which case the periodi` of the 'swing will vbe considerable, relativelyA to the periodA occupied by the rotation. 'ln the examples show-n lon the accompanying drewings such a peridic ratio has been adopted.

The desired change of position and direction of the nozzle is effected by a portion oi the energy of 1h e water supplied for distribution, operated by a smellvane-carrying wheel through the medium of spur-wheels and a worm and wornrwheel.`

The accompanying drawings show two constructional modifications.

'ln these drawings :-l.i`igures 1-3 are a verticel section, a plan and apart end. elevation respectively of one form of construction. Fig. si is e diagram showing the spiral path which is watered, und Fig. 5 is a ver tical section of .a 'modiied form of constructionwhich is adapted to water ereas which have a noncircular boundary line.

vReferring first to Figs. the water is conducted under pressure 'to the distributer through a hose which is connected to the admission pipe fr from which it flows through a turbine wheel I) formed with inclined venes. Before, reaching the wheel Y), the water passes between inclined guide-blades al formed within the admission pipe c which guiden blades give a twist to the water flowing between them, .the twist being utilized in driving the wheel, and taken outof the water by the lire-action thereof, so that the further progress ci the water is with little or no whirl. On leaving the wheel the water enters a casing ein which the spindle b1 of the wheel bv is mounted and from c the water flows through a vertical pipe l rotatably mounted within a 'bush el which passes through a central aperture in the base plete 'f1 The hush c being; screwed tightly intc'tl'te c will serve to tasten c and 'to the hase plate f and provide a vertical hearing .tor the pipe al. 'Lo the up 3er end et the vertical pipe o5 is secured an elbow g directed radially, and.l projecting JErom this is an ei;- tension it which carries, pivotally mounted thereon, the socket i oi'- an upward project in@a converging nelzzle j through which the issuing stream-of water is directed.

The motive power for deviating the petit of the projected. stream is derived from the f wheel :b by means of the rotating spindle b1 which emergesthrough the casing c and hes secured to itsl extremity e worm which gears with e. wormwheel m keyed. to a spinelle n which is mounted in a bearing provided in the buse f. To the upper end of the spindle n is keyed a pinion o which gears simultaneously with tw. spur-wheels i and Q one of which has one or more teeth in eX- cess of the other. The wheel ,e is secured to the before mentioned vertical pipe d, which thereby is caused to rotate. The other wheel Q'cerries a rollenface 1* whereby the angle of elevation of the axis of the nozzle undergoes a gradual change, causing the projectedv stream of water to `drop onto the surface oi' the ground in s. spiral path the radius of which gradually increases up to e limit and then gradually diminishes toL e minimum, and so on successively.

rlhe gradual change oi' the 'angle oit' elevation or' the nozzle 1s derived from its slow angular displacement relatively to the race 1", which is due to the difference in the number of teeth in the wheels p and g. The mechanism for varying the angle oi elevation of the nozzle is constructed as follows Formed in 011e with the before mentioned elbow g 1s a bearing;` ior a horizontal spindle ed not only to distribute water over an open area for cooling or cultivation purposes, but

a to which, at one end, is secured a lever arm it can also be employed as a re extinguisher t carrying a roller tl which traverses the race fr and, at the other end, a lever-arm u connected by a link fu to the delivery nozzle 0n the spindle s is a. sprinl w so strained as to press the roller on to the race r. The 'vertical contour of the race 'r is such as to cause the angle oi elevation of the axis of the nozzle to diminish from being exactly or approximately a ,right-angle, to such a degrec as would eil'ect the desired range oi' distribution ol the stream of water and subsequently cause a gradual increase oi. the angle and so on repeatedly. ',lhe radial died tance from the center of rotation oil the roller't is made adjustable by means of the pinching screw 1`- and thereby the area Vof the ground watered can be regulated as de# sired. The time or-upied by a rotation 0i 4the nozzle around the central vertical axis ot the machine. will be normally the same at all angles of elevation. Accordmgly 1n order to compensate for the'greater lengthv olf surface over which the water is distributed as the radins increases, the roller race 1s so shaped that the nicrement per revolution of whereby the water will automatically be directed so as to impinge in turn over every portion of the ceiling, wallsv and door oit a surrounding;` building, or alternatively the water distributer may bel affixed in an in- 'verted manner to the center of the ceiling oi' a large room.v When used for tire extinguishing it will be desirable that it be automatically started into action by some ager t' -communicating with said pipe,

the radius oi' the spiral gradually diminishes as shown in Fig.

lfig. 5 shows a moditication of the coustruction. In this a device is added whereby, in addition to the regular and gradual tilting' oi' the nozzle etiected by the race i, a secondary tilting action is superposed. ly this means the contrirane can be adapted to water a non-circular arca, such as a rectangular grass-plot for example. secondary tilting device comprises a camplate a, the plan of which is an annular ring having four elevated portions situated on radial lilies which lie in the directions oi the sides of the rectangular area to be watered, therebcing depressions between the elevations the lowest portion ot' which are situated on radial lines directed towards the corners or' the rectangle, `the elevations in the direction of the shorter side being higher than the two intermediate elevations. 1- loose pin 1 1/ mounted in the before mentioned wheel p rides on this cam-plate and by pressing' upwards beneaththe wheel q alternatively raises and lowersthe race 1" increasing'V the angle of elevation of the" nozzle when raised and diminishing the range of The which under the influence of an abrupt ine of temperature would be set into operation.
