LAWN-SPRINKLER.

srncxrrcnrron forming part of Letters Patent 115,586,161, dated July 3, 189w.

Application filed August 10, 1396. Serial No. 602,315. .(No modelfl To all 1072,0121 it may concern:

Be it known that I, Isaac WILLIAM PLEAS- ANT BUCHANAN, a resident of Lebanon, in the county of-Wilson and State of Tennessee-,have

invented certain new and useful Improvements in Lawn-Sprinklers; and I do hereby .declare the following to be a full, clear, and exaetdeseription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to an improvement in lawn-sprinklers, the object of the invention being to construct a lawn-sprinkler which shall be automatic in operation and by means of which a considerable area can be watered effectually and in acomparatively short-space of time.

A further object is to produce a sprinkler, which shall be simple in construction, by means of which a large quantity of water can be evenly distributed over a correspondingly large area of ground, said sprinkler being so constructed as to be ornamental in appear ance and effectual in all respects in the per formance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a structure embodying my invention. Figs. 2, 3, and i are views showing dilferent positions which the parts assume during the operation of the apparatus. Fig. 5 is a view of a modification, and Fig. 6 is a detail view. I

A represents a frame, which may be made of metallic rods or tubing and may also, if desired, be nickel-plated or otherwise ornamented. The base portion of the frame or stand A comprises three legs 1 2 3, united at their upper ends to the corners of a triangular frame 4. The leg 3 will preferably be made in two sections normally sccured'together by means of a suitable clamp 5, whereby said leg can be adjusted as to length so as to permit the apparatus to stand level when used on uneven-ground.

A triangular frame 6 is disposed below the frame 4 and secured at its corners to the legs 1 2 3. The body portion of the stand comprises three upright rods or bars 9 10 secured at their lower ends to the corners of the triangular frame 4 and having secured to their upper ends a ring B, of hard metal, such as steel, the rods or bars 9 being preferably continuations'of the legs 1 2. The bar or upright 10 may be made somewhat larger'than the bars or uprights 9 and is made with a vertical slot 12 for the accommodation of the screw of aclamp 13. This elampcomprises 'a plate a, disposed against the bar or upright 10, a post I), projecting from said plate, clamping-arms 15, projecting from said post and adapted to receive and hold a hose-pipe 14,

a screw c',passing through the slot 12 in the baror upright 10 and entering said plate, and a shoulder d on said screw to bear against the outer face of the bar or upright 10. The ring B is made in its upper edge with a groove g, in which an endless series of ratcl1etteeth h are located, the height of these teeth being somewhat less than the depth of the groove 9.-

Upon the ring B a movable device which for convenience I will term a rotator is disposed. The rotator 0 comprises in its structure a rectangular frame16, supported on said ring by means of arms 0 cl e f. The frame 16 is preferably of such size that its longest diameter will be about one-half the diameter of the ring B, and at each end said rectangular frame is provided with collars 18, having angular openings, and through said collars a transverse bar 19 is adapted to pass loosely. The transverse bar 1'9 is provided between its ends with a ring 20, through which-the hosefpipeis adapted to pass. Stops 21 21 are attached to the arms 0 d and adapt ed to engage the inner face of the ring B, said stops being preferably made adjustable.

Stops 22 23 are adj ustably attached to the arms e f and are normally disposed on said arms at points intermediate of the ring B and the rectangular frame 16.- A'collart' is loosely mounted on each arm 0 d and prevented from lateral displacement by the walls of the groove g. From each collar i a dog j projects and engages the ratchet-teeth h. I

The hose 14 is passed up through the ring 20 of the rotator, which is of such diameter asito permit the hose to pass through it loosely, so as to avoid any binding between said hose and ring. The hose will be pulled has made a portion of a revolution.

through the ring 20 untildhe nozzle at the end of said hose will be about one foot (more or less) from the ring. The clamp 13 will be made to grasp th'ehose. \Vhen the hose has been thus attached to the apparatus, the free ornozzle end thereof will hang loosely over the top of the stand or frame A. Should the water-supply be now turned on, the frictional contact of the water against the curved free end of the hose will cause it to rise. The force of the water which thus caused the free end of the hose to rise will also cause it to move backwardly, this backward movement being permitted by the sliding transverse rod or bar 19. of its movement, the ring in the center thereof will strike the end of the rectangularframe -16, and by the jar th-us caused the free end of the hose will be thrown over, as indicated by dotted lines in Fig. 1. The jar caused by the engagement of the ring 20 with the end of the rectangular frame will also cause saidframe to move on one of the stops or pins 21 as a pivot until the adjustable stop 22 or 23 engages the ring B. By this time the free end of the hose will have completed its oscillatory movement in the arc of a circle and will be thrown back by theaction of the force of the water in the same manner as above explained, but now a new portion of the ground will be watered, as the rectangular frame 16 This action of the apparatus will continue, the nozzle end of the hose oscillating back and forth in the arc of a circle and the rectangular frame making a slight movement at each oscillation of the end of the hose, until the frame 16 has made a complete revolution and a circular path of ground has been watered.

By providing the ratchet device above'described all lost motion when the rotator turns on the pivot pins orjstops will be prevented.

Without the ratchetdevice little irregularities of trend or flexibility of the hose-pipe would tend to interfere with perfect rotation of therotator, but with said ratchet devices the operation of the rotator will be uniform regardless of the irregularities above mentioned. I I

I have demonstrated byactual experiment that by means of my improved apparatus-I am enabled to thoroughly water a very large area of ground in a comparatively short space of time.

It will be observed that the movements of the hose are above the clamp 13, and thisclamp'ismade adjustable, as above explained, to accommodate the apparatus to hose-pipes of different degrees of flexibility and different pressures of water. In order to insure the accurate operation of the devices above described, at the upper end of the stand the apparatus should be level, and for this purpose one of the legs is made adjustable, as above described.

When it is desired to water a rectangular piece of ground, the stops 22 23 will be move When the bar 19 reaches the 'end'.

out on the arms ef until they engage the ring 13, so as to prevent the rotation of the rectangular frame ll).

The hose-pipe used may be flexible throughout or it may be made of flexible and rigid sections, if desired.

Where the-pressu re is more severe than ordinary the free or nozzle end of the hosepipe might vibrate so rapidly as to cause un" necessary friction, the full throw of the hose: pipe would not be utilized and the diameter of the watered area would be shortened. To insure the proper vibration of the nozzle end of the hose-pipe under varying, pressures of water, I prefer to i'u'ljustably attach a weight 26 to said hose-pipe between the rotator (3 and the nozzle.

Instead of the transverse sliding bar 10, above described, the recta'ngularframe 16 may be made withan elongated slot 27, in which the hose can move back and forth, as shown in Fig. 5

My improvements are simple in construe: tion, comprise few parts, are ornamental in appearance, will operate to distribute water thoroughly over a large area, and are eifcctu'al in all respects in the performance of their functions.

.Various slight changes might be made in the details'of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not-wish to limit myself to the precise details of construe Patent, is-
