TRAVELING LAWN-SPRINKLER.

Specification of Letters Iaten't.

Application'med April 20, 1916. Serial No. 92,473.

To all whom it may concern: Be it known. that we, WILLIAM C. Tom) and JAMES W. PoMnRoY, citizens of the D- minion of Canada, residing at Victoria, in the Province of British Columbia,'Canada, have invented certain new and useful improvements in Traveling Lawn-Sprinklers, of which the following is a specification.

This invention relates to a rotatable sprinkler of that class wherein the water is delivered in a free end of a pipe which travels in a circular path about a central standard to which a ed by a small impact water service is connected.

The device is an improvement on that on which Patent No. 1,108,528 was granted to us on the 25th August, 1914, and the improvement is directed to the use of a rotatable inclined spraying nozzle instead of a rotatable reaction sprinkler such as is set forth in the aforeme'nt'gmed patent, rotation of the inclined nozzle ibout it's axisand rotation of the wheel which supports the free end of the radial pipe and carries it in a circle around the central standard, being efiectturbine through which the water passes to the spraying nozzle.

It is found that the nozzle will deliver the spray of water to a greater distance than it can be thrown by the use of a rotatable "sprinkler and this rotatable spraying nozzle mounted. on the end of the radial pipe gives a considerably increased radius of action.

eral incidental features to which attention is drawn in the following specification, reference being made to the drawings by which it igsaccompanied, in which:

1 kler complete showing the as mounted on the free end of the central standard about which it circles.

Fig. 2 is a part section through the axis of the water delivery to the turbine and therefrom to the spraying nozzle.

Fig. 3 is a plan of the same, and Fig. 4, a side elevation looking in the direction of the arrows 4. V

In these drawings 2 represents the tubular central standard which is connected at 3 to a water service which may either be a permanent connection to an underground water distribution pipe or may be made by means of an ordinary garden hose pipe. About on the pipe itself between collars. 'plpe 4 is finely divided state from thea pinion 14, the teeth of teeth formed in the edge of the rim of the gure 1 1s a side elevation of the sp'rinspraying device this central standard 2 the horizontally disposed pipe 4 of any convenient length is radially movable, and the free end of it is supported on a wheel 5 preferably mounted If the of any considerable length the same :may be trussed to impart the required rlgldlty, or it may have an intermediate sup.- port wheel 6 to sustain its weight.

The free end of the radial pipe 4 is upturned as at 7 outside the supportwheel 5, and secured on the .upper end of the upturned portion 7 is a light metal casing 8 within which is rotatably mounted a turbine wheel 9. The shaft 10 of this turbine has a worm 11 secured on it outside the easing, which worm meshes in the teeth of a worm wheel 12 secured on a shaft 13 rotatable in a bearing secured or integral with the casing 8. v f On the lower end of the shaft 13 is secured which mesh with support wheel 5.

I The direction of the upturned portion 7 of the radial pipe is approximately tangential to the periphery of the turbine and the water delivers to the vanes or buekets'of the turbine through a, conical delivery jet 15.

.The water delivery from the turbine 1s parallel to the axis of the jet 15 and in a bushmg 21 secured in it is rotatably mounted a delivery pipe 16 which is gland-packed or The present invention also comprises sevhas other provision to avoid leakage.

On this rotatable pipe 16 a small gear wheel 17 is secured,- the gear wheel having a diametrically elongated aperture 18 in which it is adjustably secured on the pipe 16 between nuts threaded thereon, so that any desired measure of eccentricity within the scope ofv the elongation 18 may be imparted to the periphery of the gear. The teeth of this gear wheel 17 mesh with those of a corresponding wheel 19 secured in a similar manner upon the upper end of the worm-wheel shaft 13.

On the upper end of the delivery pipe 16 is secured by a ball and socket connection a bent nozzle pipe 20, so that the angle of deliver the water from the nozzle may be -varie to suit the requirementsof the pres- Patented Feb. h, limit.

pipe 4, 7 and through the turbine 9, not only directly rotates the nozzle 20 about the axis on which it is mounted but through the worm, 11 and worm wheel 12 slowly drives the support wheel 5 and thereby carries the rotating sprinkler around a circular path about the standard 2.

If rotation of the Water distributing nozzle 20 is uniformit will obviously bestow the same amount of water within the circle of its path, as it does outside the same, although the area to be sprinkled outside. is much greater than that Within. It is to correct this that the gears 17, 19 are eccentrically mounted on their axes, so that the rotational velocity of the nozzle is reduced during the outer part of its movement and increased during the inner part.

aving now particularly described our invention, we hereby declare that what w e claim as new and desire to be protected in by Letters Patent, is:
