LAWNSPRiNKLER.

SPECIFICATION forming part of Letters Patent No. 494,847, dated April 4, 1893.

Application filed September 22, 1892. Serial No. 446,574. (No model.)

To all whom it may concern..-

Be it known that l, RoBEET P. CREED, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Lawn-Sprinklers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. i

My invention relates to improvements in lawn-sprinklers; and it consists more especially in a lawn-sprinkler adapted to automatically direct its stream to every side, and that, during its operation, will continually change the direction of the stream.

My invention consists also in certain features of construction and in combination of parts hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation, partly in central Vertical section, of a lawn-sprinkler embodying my invention. Figs. 2 and 3 are top plans showing the moving parts in different positions, respectively, assumed in the operation of the device, the position of parts in solid lines, Fig. 2, corresponding to that shown in Fig. l. Figs. 4 and 5 are transverse sections, on line 4 5, Fig. 1, excepting that the position of parts in Fig. 5 correspond to that in Fig. 3. Fig. 6 is a left hand side elevation of members E and e relative to Figs. l and 2.

Referring to the drawings, A represents a supporting-frame or stand adapted to be placed upon the lawn to be sprinkled and comprises a centrally located upright member, a, that, at its upper end, has rotatably mounted thereon a waterchamber, B. A preferable construction is shown in Fig. l of the drawings, wherein the casin g of the waterchamber has an annularly and downwardly hanged opening at the bottom, the iange b whereof is internally threaded to engage corresponding threads on the upper end of member a, of the supporting-frame or stand and wherein said mem ber of the supporting-stand is no more than a pipe in open relation with the aforesaid water-chamber and terminates, at its lower end, in a water-chamber, a', that is provided with a nozzle, a2, for the attachment of the water-supply hose or pipe (not shown).

The casing of the water-chamber, at diametrically opposite sides, has annnlarly and outwardly flanged openings, the flanges b whereof are internally threaded and aord bearing for a horizontal correspondingly externally threaded pipe-section, C. Pipe C is closed at one end preferably by means of an elbow, C', that has connected therewith a depending arm d, terminating in a weight or poise D.

Pipe C, at suitable intervals, has lateral ports, C2, for establishing open communication between said pipe and water-chamber B. At the opposite or discharging-end, pipe C is in open relation with an upright pipe, E, that is rigidly connected with pipe C preferably by means of an elbow, C3, pipe E and weight or poise D projecting or extending in diametrically opposite directions. To the upper end of pipe E is attached a piece of bent or curved hose or flexible tube, e, that, at its upper or free end, terminates in a discharging nozzle, e. Member b of the casing of water-chamber B has a depending projection, b2, and pipe a is provided with a laterally-projecting pin, lug or member a3 adapted to be engaged by projection b2, and serve as a stop to limit the rotation of the water-chamber and attachments in either direction.

The bend or curvature in tube e is of the greatest importance as will hereinafter more fully appear. Pipe E, is preferably somewhat curved at its upper end, as at E', Fig. l, and the curvature or bend in flexible tube e constitutes a continuation of curve or bend E. Pipe E and weight or poise D being rigidly connected with horizontal pipe C it follows that said parts will oscillate together.

The operation of the device is as follows:- Suppose that when the water-supply is turned on the parts are thrown or actuated into the position shown in Fig. l and in solid lines Figs. 2 and 4, wherein pipe E and weight or poise D are tilted as shown, and wherein said iiexible tube e is curved or bent so as to inoline upwardly and to the right, that is, more or less in the direction of the length of the axis of oscillating'pipe C, (see Figs. l and 2) and is also curved or bent so as to incline IOO more or less laterally away from said pipe in a direction opposite to that of the location of weight or poise D. (See Figs. 2 and 6.) The bend or curvature affording the first mentioned inclination is preferably in the piece of hose or flexible tube before its application, but a piece of straight hose or flexible tubing may be used and given the desired curvature or inclination after it has been attached to pipe E. The other inclination of said hose or flexible tube, hereinbefore referred to, that is, the inclination in a direction opposite to the location of weight or poise D, is obtained from the weight of the hose or tube and the nozzle thereto attached.

ln the operation of the device the escape of the water at the discharging-nozzle, creates an unbalanced or back-pressure, that, owing to the inclination of hose or tube e upward and in the direction of the length of the axis of tube C, will cause pipe E and attachments to revolve in a direction opposite to the di,- rection in which the discharging-nozzle presents,and referring to Fig. 1 and to solid lines Figs. 2 and 4:, wherein projection h2 of flange b of casing B is at the left of stop 0.3, the parts will be revolved in the direction indicated by arrow Z until projection b2 of the casing of water-chamber B comesinto engagement with the right-hand side of stop 01.3. (See dotted lines Figs. 2 and 4.) It will, therefore, be observed that in the movement-of the parts just described pipe-section C will have made the greater part of a rotation in a horizontal plane, arm d with weight or poise D will have described a truncated cone and pipe C will have described an inverted truncated cone. The revolution of the parts in the direction indicated by arrow Z having been stopped by the engagement of member b2 with stop a3, the partswill not cease to be active, for, owing to theinclination of hose or liexible tube @and attachednozzleinthedirectionupwardandlaterally of horizontal pipe C, opposite to the `location of weight or poise D, resulting from the weight of said hose or flexible tube and attached nozzle, in addition to the action of weight or poise D, it follows that said parts will be oscillated in the direction indicated by arrow Z', Fig. 2, to the position shown in solid lines Fig. 3, whereupon the parts will again revolve but ofcourse in a direction indicated by arrow Z2, Fig. 3, the reverse or opposite direction of that first taken because the inclination of hose or tube e and attached nozzle is in the opposite direction, until projection or member b2 of flange b of the casing of chamber B will again have engaged the left-hand side of stop a3 (see dotted lines Figs. 3 and 5), and arm d with weight or poise D will have again described a truncated cone and pipe E will have again described an inverted trunoscillate, viz., in the direction indicated by arrow Z3, Fig. 3, to the position shown in Figs. 1, 2 and 4, and so on, the parts alternately revolving and oscillating, and continually changing the direction of the stream.

I would here remark that when the parts are free both to revolve and oscillate, they will revolve owing to the predomination of their tendency to revolve.

It is, of course, apparent that the oliice of weight or poise D is that of a counterbalance to maintain the device properly bal.- anced so that the device, when in operation, will not be knocked down by the unbalanced or back-pressure of the water hereinbefore referred to.

Flange b of the casing of water-chamber B, adjacent stationary pipe a, is preferably provided with a lateral screwthreaded hole (not shown) for the reception of a set-screw F that is adapted to engage pipe a and securely lock the parts as against revolving about said pipe in case it is desired to have the parts merely oscillate in a vertical plane as shown and described, and as indicated by arrows Z and Z3.

What I claim isl. The combination with a supporting stand, and a water chamber constructed to turn thereon, of an oscillating pipe located in the water chamber and in communication therewith, said pipe having an outlet projecting in one direction and a counterpoise in an approximately opposite direction, substantially as set forth.
