LAWN-FAN.

SPECIFICATION forming of Letters Patent No. 537,087, dated April 9, 1895. Application filed August 16,1894. Serial No. 520,443. on. model.)

To all whom it may concern:

Be it known that LOHARLES LESLIE TRAVIS, of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new and Improved Lawn-Fan, of which the following is a specification. The object of this invention is to provide a power operated fan thatis especially adapted for being set up by the side of a porch or piazza, or before an open window, for the purpose of creating a current of air across the porch or piazza or through the open window,

and thereby cooling the temperature of. the

air and making it more comfortable for the persons seated within the reach of the fan. The fan may, however, be arranged to be used in houses, offices or other places, and in factalmostany position in which it is desired to use a fan of this class.

The invention consists generally in the construction and combinations all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of a fan embodying my invention. Fig. 2 is an enlarged vertical section of the lower part of the device, showing one construction of motor. Fig. 3 is a transverse vertical section on the line xx of Fig. 2. Figs. 4. and 5 are obverse and reverse perspective views of the flights of the motor. Figs. 6 and 7 are sectional views of the shaft arrangement of the motor and fan respectively. Figs. 8 and 9 are respectively front and side views of a modified form of my device.

- In the drawings, 2 represents a suitable standard provided with a base or spreading feet 3, said standard being preferably hollow, and usually formed of a suitable le ngthof hollow pipe threaded at each end, as shown in Fig. 2, and provided with the" discharge nozzle 5secured thereto by a suitable coupling 7.

9 represents the casing of the water motor, which is provided with an opening 11 in its bottom and is secured upon the upper end of the pipe 2, the end of said pipe being screwed into the opening 11 in the bottom of said casing. When a rotative adjustment of the motor and fan with respect to the base is desired, the motor is turned down on the threaded end See Figs. 2 and 3.

Secured upon the casing 9 are the two bearings l7 and 19, arranged outside of the walls of the casing and constructed to support the shaft 21 which extends centrally through said casing. Upon said shaft 21 is the hollow or tubular shaft 23, to which is secured the water wheel 13, said hollow shaft and said wheel rotating together upon said shaft 21. The shaft 23 is provided with an opening 25, and it is also provided at'each end with a Y plug 27 formed of brass or other suitable material. This plug completely fills the end of the shaft or sleeve 23 and is provided with an opening in its center sufficiently large to permit the shaft 21 to extend through it. Oil is supplied to the hollow shaft 23 through the opening 25 so as to completely fill the inside of the shaft, and'it keeps the bearing of said shaft in the plugs 27. completely lubricated.

The bearing 17 before referred to is formed by the wall of the casing itself, said casing being thicker at this point and provided with an opening extending through it, and with a set screw 29 by means of which said shaft 21 is held in position." When it is desired to remove the wheel the shaft 21 is withdrawn and the wheel, tubular shaft 23 and the forked arm may be then removed. The upper part ofthe casing 9 above the shaft 21 is secured in position in any desired manner.

Arranged in the side of theca'sing 9 is a nozzle 31 arranged, as a screw to'permit longitudinal adjustment, by means of which the stream may be directed as required upon the flights. -A couplingl33 is provided on the nozzle by means of which suitable hose 35 may be secured thereto. The nozzle 31 is preferably arranged so as to direct the water passing through it directly toward the center of the opening 11 in the bottom of the casing,

whereby the stream of water from said nozzle strikes each bucket or fioat on the wheel firmly and moves it sufficiently to bring the next bucket under the end of the stream. In this way the stream strikes firmly upon each bucket or float and impinges upon one before it ceases to act upon the one preceding.

By means of the coupling 33 a suitable hose 35 may be connected to the casing for the purpose of leading the water thereto. A suitable hose may also be connected to the outlet end or coupling 5 for the purpose of direct ing the waste water to any convenient point. This will preferably. in practice, be directed onto the lawn, and the water which runs the motor and operates the fan will at the same time be used for watering the lawn.

Mounted upon the shaft 21 outside of the

bearings

17 and 19 is the fork 37, which is arranged to swing freely upon said shaft 21 as a center. To the upper end of the fork 37 is connected the tubular standard or arm 39, to the other end of which is connected a fork 41 carrying the shaft 43, and upon this shaft is mounted a tubular shaft 45 having secured thereon the fan wheel 47. The shaft 45 is provided with the, preferably brass, plugs 49 at its end, and with an oil hole 51, by means of which oil may be supplied to the interior of the shaft, while the plugs 49 form bearings upon the shaft 43 for the tubular shaft and fan to rotate upon. The tubular shaft 23 is provided outside of the casing 9 with a suitable wheel or pulley 53, and the shaft 45 is also preferably provided with a similar though smaller pulley 55. A belt 57 extends around these pulleys 53 and 55 so that when the mofor wheel is driven by the passage of water through the casing, the wheel 53 will be rotated, and through the medium of the belt the pulley 55 will drive the fan wheel 47 at a high rate of speed.

One arm of the yoke 37 is provided with the quadrant shaped plate 57 which is concentric with the casing 9. The edge of said plate passes between the end of the stationary lug 59 and the inner surface of the threaded thumb-nut 61. The nut 61 is arranged to screw upon a stud projecting from the end of the lug 59 and through the interior of the quadrantshaped plate 57 but close to the edge thereof, so that by turning up the nut 61 at any time the plate 57 may be clamped between the inner surface of the nut-61 and the tightening the nut 61 said plate may be fasi tened and thereby fasten the said fan support in any desired position.

In some instances I prefer to provide modified means for adjusting the fan, adapted (as pecially for adjusting it in a vertical position I where such adjustment is desired. In this instance (see Figs. 8 and 9) a vertical rod 63 is secured to the water motor and extends to any desired height. The shaft 4-3 which supports the tubular shaft upon which the fan is mounted is in the form of a stud pin secured to a sliding bearing 67 supported upon the rod 63 by means of the collars 09. A set screw 71 is arranged upon one of said collars and provides means for securing said hearing at any desired height. This bearing and the rod upon which it is located form a substantial support for the shaft of the fan. The belt wheel or pulley 55 is mounted upon the tubular fan shaft, preferably near the sliding bearing 67.

An arm or connecting rod 75 is connected to the shaft or stud pin 43 so as to turn freely thereon. The lower end of said arm is pivotally connected to the upper end of an arm 77 by a stud pin 74. A double pulley 83 is mounted on the stud pin 74. The lower end of the arm 77is provided with afork 79 which is mounted on the shaft 21 of the water motor. One belt runs from the wheel upon the water motor shaft to one of the grooves in the wheel 83, and the other belt extends around the wheel 83 in its other groove and extends around the wheel upon the fan shaft, so that said fan is driven in substantially the same way as before described by the rotation of the shaft of the water motor.

\Vith this construction the fan may be vertically adjusted to any desired height within the limits of the rod 63, and the driving belts are always kept taut and in position for running the fan.

I do not wish to limit myself Lto the construction of the water motor herein shown and described, as I may use any suitable motor for operating the driving shaft from which power is transmitted to the fan shaft. 13y standing the fan by the end of a porch or piazza it is found that a current of air is created that will extend the full length of an ordinary piazza, orby standing the fan outside of an open window upon a hot day air may be circulated throughout the entire house, and the only power required to operate the device is obtained by means of an ordinary lawn hose, and the water after being used for driving the water motor and fan may be conveyed back upon the lawn for the purpose of keeping it thoroughly watered. It will be seen therefore that the device is exceedingly simple in construction, easy of operation and that it is adapted for general use wherever a small power or a pressure of water may be obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. Thecombination, with the hollow standard, mounted upon a suitable base, of the water motor casing secured upon the upper end of said standard and communicating therewith, the wheel arranged in said casing, the inlet nozzle for directing a stream of water against said wheel and thereby rotating the same,
